Opis:
The subject of the paper is the evolution of the concept of the continental shelf in international law, shown in the context of natural prolongation of the land territory of a coastal state co-creating this concept. The starting point for the analysis are the determinations of such specialised disciplines of science as: geography, oceanography and geology, and in consequence a possibly accurate topographic description of the sea and ocean floor, determination of the most important physiographic zones and of their characteristic features. This, only formally distinguished, but treated as one whole for meritoric and structural reasons three-element sequence, formed in the order: continental shelf in geographic/physical approach - continental slope -foot of continental slope, forms a common topographic feature called the continental margin. However, the reconstruction of the continental shelf concept in international law is not limited only to the description and characteristic of the continental margin in the horizontal plane. Appropriately to the needs of the paper, and to the extent the competence of the Author allowed, the margin is also described in the vertical dimension, i.e. going deeper into the essence of the natural factor, contained basically in the geomorphologic and geologic structure of the main physiographic provinces forming the continental margin. Such a view of the above problem allowed to obtain knowledge of motivations and of various arguments forming the essence and reach of the external limit of the continental shelf in the Geneva Convention on the continental shelf of I958, called further in text the GC IV ( I958). However, most important was to show and prove the thesis that it was the natural factor that dictated and shaped stipulations in international law with respect to the discussed subject, and that this factor played an extremely important role in the evolution and development of the continental shelf concept during the period after CG IV ( I958) was adopted. The principle, contained in the ITJ ruling on the continental shelf of the North Sea that the continental shelf is a natural prolongation of the territory of a coastal state, the natural prolongation principle, was well substantiated by the geomorphology and geophysical characteristics of the continental margin. This principle was also of primary importance for the shaping of the concept of the continental shelf and of its external boundary in the United Nations Convention on the Law of the Sea of 1982, called below UNCLOS (1982).

Opis:
The Tsodilo Hills Group strata exposed in the Tsodilo Hills are an association of meta-arenites, metaconglomerates, quartz-mica schists, sandstone, red siltstone and sedimentary breccia deposited on an open siliciclastic marine shelf between the Late Palaeoproterozic and Late Mesoproterozoic, and outcropping in NW Botswana. The succession is dominated by three micaceous quartzite units interlayered with subordinate lenses and wedges of other rock types. Facies gradients from S to N are expressed by: decreasing content of muscovite at all levels of metasediment organisation from thin wedge-shaped units to thick quartzite complexes, as well as a decrease in pebble content and increase in arenaceous matrix in some metaconglomerate beds, matching regional palaeotransport direction. Well-rounded pebbles of extrabasinal rocks are flat, suggesting redeposition from a beach environment. Lenticular conglomeratic bodies with erosional lower boundaries represent infills of local incisions in the sandy bottom sediments. The abundance of laterally discontinuous lithological units reflects shelf palaeotopography controlled and modified by deposition and migration of large bed forms, ranging from megaripple marks (or submarine dunes) to sand waves. Deposition was influenced by tides and two regressive events. The older regression resulted in a marker unit of tidal mudflat-related red-bed facies: mudstone, siltstone, channel-fill sandstone and sedimentary breccia. The second regression is indicated by a tabular conglomerate marker reflecting increased input of coarse terrigenous material.

Opis:
2-Dimethylaminoethyl azide (DMAZ) is a good replacement for the hydrazine family in space industries. In this article, the accelerated ageing test method was applied for predicting the shelf life of DMAZ. The effective parameters on the storage of the fuel were temperature, the type of gas atmosphere with its pressure over the liquid fuel, and moisture. Appropriate conditions for DMAZ storage were N2 at a pressure of 3 bar and a moisture content of 0.05 wt.%. The sigmoid form of the decomposition curves obtained revealed that the decomposition reaction is autocatalytic. Modelling of the decomposition rate showed that the shelf life of DMAZ was 7.73 years at 25 °C.

Opis:
Sedimentary features of the Cambrian-age succession transected in seven borehole cores sited in the Podlasie region document vertical and lateral variations of shallow-marine sedimentary facies, deposited at the rifted western margin of the Baltica Palaeocontinent. The boreholes are distributed along two lines of cross-section (E–W and NE–SW) running roughly perpendicular to the margin of the palaeocontinent. The easternmost borehole represents a proximal setting located on a relatively stable, shallow basement in the east; the remaining boreholes document conditions of deposition in the subsiding shallow-marine basin, extending towards the SW. Fourteen sedimentary facies defined on the basis of their lithological and sedimentary features are interpreted in terms of the sedimentary environments they represent. Strata deposited upon the stable craton in the east document a stratigraphically condensed succession of proximal facies, 240 m thick, whereas a sequence three times thicker is positioned distally, 170 km to the west. Facies associations in the proximal section represent the lower to upper shoreface in the lower part of the section and evolve upwards to the intermediate shoreface. Facies complexes in the remaining, intermediate and distal areas form a symmetrical megasequence, composed of a positive (i.e., fining-upwards – FU) transgressive sequence, overlain by a negative (coarsening-upwards – CU) regressive sequence. The vertical arrangement of the sedimentary subenvironments during the transgression indicates a tidally influenced shoreline followed by oscillations between the swash zone, the upper, intermediate and lower shoreface, and the offshore. The symmetry of the megasequences and the rhythmic pattern of the component facies complexes indicate that the intensity of supply in the terrigenous material and the efficiency of its reworking and redistribution within the basin were similar during the transgression and the regression. The facies types and variations within the basal part of the succession reflect syndepositional movements of tectonic blocks parallel to the rifted basin margin. Differences in total thickness and facies associations between the two lines of cross-section approximately perpendicular to the basin margin indicate that sedimentation was also influenced by a synsedimentary hinge fault, extending in a WSW–ENE direction.

Opis:
Edible flowers are food products that are usually eaten fresh without prior heat treatment. Due to their chemical composition and low degree of processing, they can be an excellent breeding ground for microorganisms, and thus a source of infection. Methods of their preservation include proper packaging and storage at low temperatures. Therefore the aim of this study was to evaluate the effect of type of packaging (vacuum-sealed polyamide/polyethylene bag and polyethylene terephthalate box) on the microbial contamination of edible flowers including nasturtium, calendula, and daisy during refrigerated storage. The counts of selected pathogenic bacteria, total yeasts and moulds on the day of harvesting and after 1–3 days of refrigerated storage were determined. The results showed that the edible flowers did not contain Salmonella sp. or Escherichia coli (except nasturtiums), while all flowers contained both yeast and moulds at counts about 4–5 log cfu/g, and Staphylococcus aureus at numbers ranging from 1.89 to 2.72 log cfu/g. The differences in the counts of moulds and S. aureus were statistically significant depending on the type of flower. Neither the type of packaging nor storage time under refrigerated conditions influenced the degree of microbial contamination of the flowers.

Opis:
In the Cambrian, the Lublin Basin was a shallow-water area, located on the western edge of the Baltica palaeocontinent. The Cambrian sedimentary sequence, forming the lower part of the sedimentary cover of the North European Platform, is lithologically diversified and reflects dynamic variation in depositional environment. This paper presents the distribution of palaeofacies and sedimentary environments in the early Lublin Basin, including changes in their lateral extent during its evolution in the Cambrian. In order to evaluate the facies architecture of the Lublin Basin, a sedimentological analysis was carried out. On the basis of the detailed logging of drill cores, lithofacies made up of conglomerates, sandstones, mudstones and heterolithic deposits were distinguished; 16 lower-rank sublithofacies were identified. Their specific assemblages are indicative of shelf-type lithofacies associations, i.e. (1) tidal flat with muddy, mixed and sandy tidal plain sublithofacies including subtidal channels; (2) barrier-lagoon; (3) shoreface with lower, middle and upper shoreface subassociations; and (4) offshore with upper and lower offshore subassociations, including sandy tidal ridges. During the early Cambrian, the lateral variability and environmental succession indicate a transgressive, long-term trend and the migration of a lagoonal environment across wide tidal plains and the shoreface up to an offshore environment. The Lublin Basin reached its greatest lateral extent and maximum depth in the upper lower Cambrian. Next, an opposite trend began and during the middle Cambrian a regression cycle is recorded in successive changes in sedimentary environments that reflect a progressive shallowing. Multiple changes in adjacent environments indicate repeated and cyclical, lower-rank ingressions.

Opis:
The Tsodilo Hills Group is an association of meta-quartzites, meta-conglomerates and quartz-mica schists altered to kyanite metamorphic grade and outcropping in NW Botswana. The unit is a part of the regional Neoproterozoic–Lower Palaeozoic succession deformed during the Pan-African orogenesis and present in the Damara belt of Namibia to the west, in which the main orogenic event occurred at ca. 534–516 Ma, and in the Katangan suite of the Lufilian arc in Zambia and the Democratic Republic of Congo to the north-east. Sedimentary structures, textures, mineral composition, facies trends and palaeocurrent patterns suggest that the deposition of the Tsodilo Hills Group strata took place on an open continental shelf influenced by tides and supplied with siliciclastic material derived from a source area elevated to the south of the depository. The ongoing sedimentation was punctuated by two regressive stages. The older one is reflected by an association of red mudstone, siltstone and sandstones/quartzites, and incised in them channel-fill sandstone bodies with bimodalbipolar palaeocurrent patterns, which are interpreted here as deposits of tidal mudflats intersected by tidal creeks. Enrichment of these rocks in phosphorous was probably caused by upwelling of deep ocean waters reflecting sea-level changes. The second regression was related to an increased input of terrigenous material and is indicated by a conglomerate marker bed. Numerous shear zones, a few small-scale reverse faults and one major thrust, displacing strata towards the south-west, deform the succession. The degree of deformation evolves laterally along the strike of this structure from a prominent thrust in the southern part of the Tsodilo Hills to a thin shear zone in the north.
Praca prezentuje w zarysie nowe wyniki badań nad grupą Tsodilo Hills, odsłaniającą się w północno-zachodniej części Botswany. Jednostka ta reprezentowana jest przez zmetamorfizowane skały terrygeniczne: kwarcyty, piaskowce, zlepieńce i łupki muskowitowe będące cześcią sukcesji deponowanych od neoproterozoiku, a następnie zdeformowanych we wczesnym paleozoiku podczas orogenezy panafrykańskiej, której maksimum w orogenie Damara w Namibii, bezposrednio na zachód od dyskutowanego obszaru, przypada na okres ok. 534-516 Ma. Skały te reprezentują kyanitową fację metamorficzną. Grupa Tsodilo Hills leży w obrębie pasma orogenicznego Damara, które ciągnie się z Namibii poprzez Botswanę. Jego przedłużenie ku północnemu wschodowi znane jest jako orogeniczny łuk lufilianski (“Lufilian arc”) rozciągający się pomiędzy Zambią na południu a Demokratyczną Republika Konga (DRC) na północy. Struktury i tekstury sedymentacyjne, systemy paleoprądów oraz kierunkowe zmiany facjalne sugerują iż depozycja grupy Tsodilo Hills przebiegała na obszarze otwartego szelfu pozostającego pod wpływami pływów i zaopatrywanego w materiał terrygeniczny dostarczany ze strefy źródlowej położonej na południe od obszaru sedymentacji. Postępująca depozycja została przerwana przez dwa epizody regresywne. Świadectwem pierwszej regresji jest kompleks czerwonych mułowców, pyłowców i piaskowców/kwarcytów erozyjnie rozciętych przez kanały wypełnione piaskowcami o dwukierunkowym warstwowaniu skośnym, interpretowane tutaj jako osady równi pływowych. Wzbogacenie tych skał w fosfor spowodowane było prawdopodobnie przez ‘upwelling’ głębinowych wód oceanicznych wywołany eustatycz nymi zmianami poziomu morza. Druga regresja, której odbiciem jest poziom zlepieńcowy, wywołana była wzrostem intensywności dostawy materiału klastycznego. Sukcesja osadowa jest zdeformowana przez liczne fałdki ciągnione, małoskalowe uskoki wsteczne oraz jedno nasunięcie. Stopień deformacji zmienia się stopniowo wzdłuż biegu tej struktury tak, że wyraźna strefa nasunięcia w południowym sektorze Tsodilo Hills ewoluuje lateralnie w cienką strefę skał nieznacznie zdeformowanych przez ścinanie w obszarze północnym. Kierunkowe struktury tektoniczne wskazują, iż lokalne ruchy nasuwcze skierowane były ku południowemu zachodowi.

Shelf space allocation
Opis:
Aim/purpose – Shelf space is one of the most important tools for attracting customers’ attention in a retail store. This paper aims to develop a practical shelf space allocation model with visible vertical and horizontal categories. and formulate it in linear and non-linear forms. Design/methodology/approach – The research is mainly based on operational research. Simulation, mathematical optimization, and linear and nonlinear programming methods are mainly used. Special attention is given to the decision variables and constraints. Changing the dimensioning of the decision variables results in an improvement in the formulation of the problem, which in turn allows for obtaining an optimal solution. Findings – A comparison of the developed shelf space allocation models with visible vertical and horizontal categories in linear and nonlinear forms is presented. The computational experiments were performed with the help of CPLEX solver, which shows that the optimal solution of the linear problem formulation was obtained within a couple of seconds. However, a nonlinear form of this problem found the optimal solution only in 19 out of 45 instances. An increase in the time limits slightly improves the performance of the solutions of the nonlinear form. Research implications/limitations – The main implication of research results for science is related to the possibility of determining an optimal solution to the initially formulated nonlinear shelf space allocation problem. The main implication for practice is to take into consideration the practical constraints based on customers’ requirements. The main limitations are the lack of storage conditions and holding time constraints. Originality/value/contribution – The main contribution is related to developing mathematical models that consider simultaneous categorization of products vertically, based on one characteristic, and horizontally, based on another characteristic. Contribution is also related to extending the shelf space allocation theory with the shelf space allocation problem model in relation to four sets of constraints: shelf constraints, product constraints, orientation constraints, and band constraints.

Opis:
The middle and upper parts of the Skały Fm, Early to Middle Givetian in age, were investigated in four sections at Miłoszów Wood in the Łysogóry Region (northern region of the Holy Cross Mountains, central Poland). The dating is based on conodonts (Polygnathus timorensis Zone to the later part of the Polygnathus varcus/Polygnathus rhenanus Zone; early Polygnathus ansatus Zone cannot be excluded) and spores (Ex1–2 subzones) and, coupled with cartographic analysis and geophysical investigation, allows correlation within the strongly faulted succession. Significant lateral facies variations within the carbonate ramp depositional system in comparison with the better studied Grzegorzowice–Skały section, about 3 km distant, are documented, thanks to conodont-based correlation of both successions. Foraminifers, fungi, sponges, rugose and tabulate corals, medusozoans, microconchids and cornulitids, polychaetes (scolecodonts), molluscs (bivalves, rostroconchs, and gastropods), arthropods (trilobites and ostracods), bryozoans, hederelloids, ascodictyids, brachiopods, echinoderms (mostly crinoids, rare echinoids, holuthurians, and ophiocistoids), conodonts, fish, plants (prasinophytes, chlorophycophytes, and land plant spores), and acritarchs are present. Brachiopods are the most diverse phylum present (68 species), other richly represented groups are bryozoans and echinoderms; in contrast, cephalopods and trilobites are low in diversity and abundance. The muddy, middle to outer ramp biota (200 marine taxa, including 170 species of marine animals, 22 photoautotrophs, 6 forams) represents a mixture of allochthonous shallower-water communities (upper BA3), including storm- and possibly tsunami-affected coral mounds, and autochthonous deep-water soft-bottom brachiopod (e.g., Bifida–Echinocoelia) communities (BA 4–5). The richness and diversity of the Miłoszów biota is relatively high, comparable with other approximately coeval pre-Taghanic ecosystems during the Devonian climatic deterioration (cooling). Preliminary data indicate that in the Holy Cross Mountains, no large-scale replacement of brachiopod (and probably many other benthic ones, like crinoids) communities took place between the Early–Middle Givetian and the Early Frasnian, in contrast to the demise of the Hamilton/Upper Tully fauna in the Appalachian Basin. Such a similarity of pre- and post-Taghanic faunas does not exclude the occurrence of environmental perturbations and transient community turnovers, caused by immigrations during the Taghanic Biocrisis, but evidences the successful recovery of the indigenous biota.

Three experiments were carried out to assess the effectiveness of the so-called new technologies in extending birch tree sap shelf life. In the first one, microfiltration of birch sap was carried out using 0.22 μm, 0.45 μm and 0.8 μm filters. In the second experiment, ultraviolet radiation was applied for 5, 15 and 45 minutes. In the third experiment ultrasound was applied with one-, two-, three- and four-fold use. Regardless of the pore diameter, all the microfiltered samples were non-perishable for at least a month at room temperature. The efficacy of ultrasound was also demonstrated. The four-fold use of ultrasound proved to be the most effective and prolonged the shelf life of birch sap from one to two days at room temperature and from four to twelve days in refrigeration conditions. In turn, the use of ultraviolet radiation did not extend the shelf life of birch sap, although in refrigeration conditions the clouding was significantly inhibited. However, there is no doubt that among the so-called new technologies, microfiltration is the most advantageous in extending shelf life of birch sap and has perspectives for use in food industry.

Opis:
Silurian strata, stretching along the western margin of the East European Platform from the Baltic to the Black Sea, represent a potential target for both conventional and unconventional hydrocarbon exploration. Distribution of the black shale facies, prospective for shale gas, and the reef facies, prospective for oil, has been studied in respect of palaeoenvironments. The Silurian sequence has been investigated in the territory of Ukraine (Volyn-Podillyan Plate, Dobrogean Foredeep) and correlated with the data on Moldova and Romania (Moldovian Platform). The occurrence of Silurian strata, their thickness, and petrographic and lithological characteristics allowed reconstructing the distribution of open-shelf, reef and lagoonal facies. The reef facies migrated during the Wenlock–Middle Pridoli, shifting towards the open sea and back towards the shore, and therefore has been termed a migrating reef facies. Correspondingly, the boundary between the open-shelf and reef facies was shifting. The facies distribution was controlled by the transgressive-regressive cycles, which caused the fluctuations of the shelf water depth in different time intervals of the Silurian. The shelf water depth of about 100 m, where the top of the oxygen-minimum layer impinged on the sea bottom, was the boundary between the open-shelf facies, represented by organic-rich sediments, and the reef buildups.

Opis:
The storage-stability of extractable colour in paprika powder is strongly influenced by the processing steps. The purpose of this research work was to decrease the degradation rate of extractable colour of paprika powders to 3-4 ASTA units/month and increase the shelf-life. Fractional factorial experimental design and desirability function-based approach was applied to moderate the adverse effect of the key-importance processing steps on colour agent content. Photochemical-accelerated shelf-life test was used for the empirically-based quality improvement. Post-harvest ripening, drying, sorting (seed content), milling and additives (paprika seed oil, tocopherol extract) were identified as important for the degradation rate of extractable colour. The colour stability was very sensitive to the milling and drying intensity, while proper setup of other processing steps compensated the adverse effect of drying and milling parameters. The supplementation with cold-pressed spice paprika seed oil was demonstrated as a natural way of colour stabilization. At the highest desirability value (0.986) the rate constant of accelerated colour stability test (k) and shelf-life time (θS[100ASTA]) were −0.494 ASTA units/day and 2326 days, respectively. Alternative factor level settings enabled taking into account processing-tradition and efficiency expectation. In these cases, desirability values and the predicted shelf-life were 0.5-0.8 and 712-918 days, respectively. Validation study showed that the real observed rate constant and shelf-life values met the predicted values and their 95% confidence interval.

Red raspberries (Rubus idaeus L.) are often chosen by consumers for their flavour, taste, and health-promoting properties A relevant issue related to these fruits is their high perishability. The aim of this study was to investigate the effect of the ultraviolet C light-emitting diode (UVC-LED) treatment on soil-grown and pot-grown raspberries in extending their shelf-life, maintaining their high quality throughout the preservation period, and improving features related to their phenolic compound content. The UVC-LED treatment increased the total phenolic content (158 to 200 mg GAE/100 g) and ferric reducing antioxidant power (55.3 to 78.6 mmol Fe2+/kg) of the pot-grown raspberries when the UVC-LED treatment was followed by storage in a climate-controlled room (20°C). Total anthocyanin content did not increase significantly compared to the control samples. Contrary to expectations, no effect of reducing the microbial count after storage was observed due to the exposure of raspberries to the UVC-LED radiation. The positive outcomes derived from the analyses of bioactive compounds may be implemented in further studies on the same matrix to better manage the treatment and its conditions, such as the exposure time, the distance from the LED lamps, and the UVC-rays’ dose, in order to find the best combination in terms of efficacy and efficiency.

Opis:
An impact of fiberglass fabric reinforcement on shelves made from particleboard. The research used two variants of shelves reinforcement: reinforcement by gluing fibreglass cloth on particleboard and reinforcement by gluing pre-tensioned fibreglass cloth. The results obtained for reinforced shelves were compared to the results obtained for non-reinforced shelves. The characteristics of particleboard and existing on the global market ways to reinforce furniture shelves are presented in the initial chapters. Further chapters contain the methodology and the results of fatigue tests, shelf stiffness tests and modulus of elasticity tests. Based on the test results, it was found that the cloth reinforcement of particleboard furniture shelves using fiberglass with and without pre-tension results in the strength of the shelves by 15–40%. Also, reinforced shelves deflect less than the shelves made of unreinforced chipboard.
Wpływ wzmocnienia tkaniną z włókna szklanego na półki z płyty wiórowej. W badaniach wykorzystano dwa warianty wzmocnienia półek: wzmocnienie poprzez podklejenie płyty wiórowej tkaniną z włókna szklanego oraz wzmocnienie poprzez podklejenie płyty wstępnie naprężoną tkaniną z włókna szklanego. Wyniki uzyskane dla półek wzmocnionych zostały porównane do wyników uzyskanych dla półek niewzmocnionych. W początkowych rozdziałach pracy przybliżono charakterystykę płyt wiórowych oraz istniejących na rynku sposobów na wzmacnianie półek meblowych. Dalsze rozdziały zawierają metodykę oraz wyniki badań takich jak badania zmęczeniowe, sztywność półek oraz badanie modułu sprężystości. Na podstawie przeprowadzonych badań stwierdzono, że wzmocnienie półek meblarskich wykonanych z płyty wiórowej tkaniną z włókna szklanego, bez i ze wstępnym naprężeniem, skutkuje wzmocnieniem płyt w granicach 15-40%. Również półki wzmocnione ulegają ugięciu w mniejszym stopniu niż półki z płyty wiórowej niewzmocnionej.

Opis:
A sediment budget for the central Vietnam shelf off Nha Trang over the last deglacial Holocene highstand period has been investigated on the basis of shallow seismic and sediment core data and empirical equations. The annual suspended sediment discharge to the Nha Trang shelf ranges from: 4.3 to 5.4 Mt/year. Estimates based on published empirical equations suggest that the sediment discharge by three main local mountainous rivers (the Cai, Dinh and Van Phong rivers) that enter the Nha Trang shelf ranges between 1.7 and 4 Mt/year, which implies that the local rivers discharge approximately 75% of the total annual sediment input to the shelf. The annual sediment supply of the Cai River is approximately 2 and 6 times higher than that of the Dinh and Van Phong rivers, respectively. The highstand sediment depocentre of the Nha Trang shelf is mostly attached to the local river outflows, indicating their importance as the principal sediment supply sources to the shelf. Additional sources of sediment supply to the Nha Trang shelf can probably be related to along-shore transport from the nearby shelves. Calculations based on seismic and sediment core data indicate that the net sediment volume storage on the Nha Trang shelf is approximately 2.15 Mt/year. Approximately 50% of the total sediment yield supplied to the shelf is probably transported along-shore to the south. The sediment budget model for highstand deposits on the Nha Trang shelf is typical for a small mountainous river basin, which is significantly different from that of the large river delta systems in Vietnam such as the Mekong and Red rivers where 90% of the river sediments are captured on the delta plain/subaqueous part and only 10% of the river sediments are transported to the nearby shelf. In contrast, most of the sediments supplied by small mountainous rivers off Nha Trang are transported to the mid-shelf, forming a shore-parallel mud depocentre.

Opis:
Shelf space is one of the essential resources in logistic decisions. Order picking is the most time-consuming and labourintensive of the distribution processes in distribution centres. Current research investigates the allocation of shelf space on a rack in a distribution centre and a retail store. The retail store, as well as the distribution centre, offers a large number of shelf storage locations. In this research, multi-orientated capping as a product of the rack allocation method is investigated. Capping allows additional product items to be placed on the rack. We show the linearisation technique with the help of which the models with capping could be linearised and, therefore, an optimal solution could be obtained. The computational experiments compare the quality of results obtained by non-linear and linear models. The proposed technique does not increase the complexity of the initial non-linear problem.

A method for estimating the water backscattering coefficient was put forward on the basis of experimental data of diffuse attenuation coefficient for downwelling irradiance and irradiance reflectance. Calculations were carried out for open sea waters of different types and the spectral dependencies were found (‘anomalous’ spectra) and explained. On this basis, a new model of light backscattering on particles in the sea is proposed. This model may be useful for modelling remote sensing reflectance spectra in order to solve the inverse problems of estimating the concentration of natural admixtures in shelf waters.

Opis:
Injera is one of the fermented foods that is made from different cereals, including sorghum, teff, maize, wheat, barley, or a combination of some of these cereals. Despite the fact that injera is a favorite staple food, mould spoilage caused by Aspergillus, Penicillium, Mucur and Rhizopus spps is a serious problem that affects the shelf life of injera, the staple Ethiopian fermented bread. There were no reports on the efficiency of spices on shelf life and sensory attributes of any of the traditional Ethiopian fermented foods especially in teff injera. Therefore, this study was carried out to evaluate the efficiency of locally available spices to enhance the shelf life and sensory attributes of teff injera. Isolation and identification of fungi that spoiled injera was carried out by standard procedures. The efficiency of spices to increase shelf life of injera was evaluated in vivo and sensory attributes of preserved injera was evaluated by 30 panelists. The results revealed that four types of fungal species belonging to the genera of Penicillium, Aspergillus, Rhizopus and Mucur species were isolated from spoiled teff injera. Teff injera containing powder and water extract of 2% N. sativa were the most preferred in terms of taste with mean rating of 6.9; ethanol extracts of 2% N. sativa was the most preferred in terms of colour and allover acceptance with mean rating of 6.9and 6.93 respectively. On the basis of the current findings, tested spices could be a good candidate to improve the shelf life and sensory attributes of teff injera. Therefore, further studies are needed to study their toxicology and isolate the bio-active components responsible for shelf life and sensory improvement from these plants.

This article is supplementary to Myrhaug (2018) and presents some probabilistic properties of the surf parameter for individual waves and the spectral surf parameter for sea states by using distributions based on data from the Norwegian continental shelf. The average statistical features given by the mean value and the standard deviation of the two surf parameters are considered. Examples of results for the surf parameter are provided for a Phillips spectrum and a family of JONSWAP spectra for wind sea, and for sea states using a joint frequency table of significant wave height and mean zero-crossing wave period for combined wind sea and swell. The spectral surf parameter results are obtained by using a joint distribution of significant wave height and spectral surf parameter, and the mean statistical properties are given for joint frequency tables of significant wave height and mean zero-crossing wave period from three deep water locations on the Norwegian continental shelf. It is also demonstrated how the results can be applied to calculate the vertical wave runup elevation for breaking waves.

Opis:
The Pelotas Basin, located on the SE Brazilian shelf, has evolved since the Aptian. Stratigraphical data from the basin can be used for delineation of the unconformity-bounded units (synthems) on the shelf, which is a first step towards a full understanding of its stratigraphic architecture, evolution, and hydrocarbon potential. Hiatuses in the Cenozoic succession of the Pelotas Basin are established with both biostratigraphic (planktonic foraminifers and calcareous nannofossils) and isotopic (87Sr/86Sr) data. The seven recognised hiatuses are dated respectively as (1) Palaeocene (Danian-Thanetian), (2) Palaeocene/Eocene boundary (Thanetian-Ypresian), (3) Eocene (Ypresian-Lutetian), (4) Eocene-Oligocene (Lutetian-Rupelian), (5) early-late Oligocene (Rupelian-Chattian), (6) early Miocene (Aquitanian-Burdigalian), and (7) middle-late Miocene (Serravallian-Tortonian). These intervals between the hiatuses are correlated with those of the Santos and Campos Basins north from the Pelotas Basin. The breaks in sedimentation that these basins have in common occurred (1) at the Palaeocene-Eocene and (2) Eocene-Oligocene transitions, (3) in the early Miocene, and (4) in the middle-late Miocene. These main unconformities outline five synthems on the SE Brazilian shelf, viz. the SEBS-1 (Palaeocene), SEBS-2 (Eocene), SEBS-3 (Oligocene), SEBS-4 (early-middle Miocene) and SEBS-5 (late Miocene-Holocene). The above unconformities are correlated with those established in the Cenozoic sedimentary successions of different regions such as Western Siberia, Arabia, NW and NE Africa, peninsular India, S Australia, the Gulf of Mexico, NW Europe, and South Africa. The only regional unconformity, near the Oligocene/Miocene boundary, coincides with the nearly-global sedimentation break. The latter was resulted from a climatic event, i.e., the ‘Mi-1 glaciation’. Thus, a eustatic origin is supposed for this regional unconformity. The other regional unconformities also correspond to global sea-level falls (probably with an exception for the Palaeocene/Eocene surface), which suggests that global eustatic movements controlled the development of the regional synthem architecture.

Opis:
Appropriate product categorization in distribution centres is important for business success because of the possibility of intuitive product finding by the picker and increased product movement. Both of these factors result in the operational efficiency of the distribution centre. The goal of this paper is to explore a model of shelf space dimensioning of storage location on a rack with vertical and horizontal product categorization in a distribution centre, where the aim is to increase total product movement/profit from all shelves of the rack. This is controlled by a packer who must complete orders by getting the goods from shelves and picking them to the container. In this problem, we develop two heuristics and compare the archived results to the CPLEX solver. The average profit ratios of both heuristics are high and approximately equal to 99%. In 10 cases, optimal solutions have been found by heuristics. The total number of possible solutions to be checked for the largest instance was reduced from 1.33 ·10156 to 1.19 ·107 thanks to the heuristic rules.

Distribution centres are the important elements of modern supply chains. A distribution centre stores and ships products. In this paper, we investigate the model of the dimensioning of shelf space on the rack with vertical and horizontal product categorisation in a distribution centre, where the objective is to maximise the total product movement/profit from all shelves of the rack which is being managed by a packer who needs to complete orders selecting the products from the shelves and picking them to the container. We apply two newly developed heuristics to this problem and compare the results to the optimal solution found by the CPLEX solver. There are 8 steering parameters that allow for reducing the search space implemented in heuristics. Among them are parameters that decrease the number of prod- ucts on the shelves, the category width range for assigning most space for the most profitable products within the category, two versions of steering parameters for the number of generated product allocations, the step parameters for the intensity of solution diversification, and the movement/profit below which the solutions are not generated. The computational results are presented and indicate that higher-quality solutions can be obtained using the new heuristics. In 10 from 15 tests, both heuristics can find optimal solutions without exploring the whole solution space. For the rest test sets, the solutions received by heuristics are not less than 92.58%.

Numerous fully cored boreholes completed in the last years in central Poland (Kleszczów Graben area, southern border of the Łódź Depression) enabled the researchers to obtain new sedimentological data on the Oxfordian-Tithonian continuous sedimentary record in the Polish part of the northern Tethys shelf. Twenty-two facies were distinguished in the sedimentological succession. The facies represent the outer-, mid- and inner-ramp environments, including evaporitic episodes and palaeosols. The facies document that the Oxfordian-Lower Kimmeridgian (up to Hypselocyclum) carbonate ramp has evolved to the Upper Kimmeridgian-Tithonian carbonate-siliciclastic ramp. Among the Kimmeridgian deposits, numerous hardgrounds, tidal channel deposits and gravity flow sediments were identified. The Kleszczów Graben sedimentary succession is discussed along with the lithostratigraphical units known from the adjacent regions of southern and central Poland.

Opis:
The growth of carbonate buildups in the northern, stable shelf of the Tethyan Ocean was the principal factor in the development of diversified sea-bottom relief in the Late Jurassic basin. Reconstruction of this relief has been a matter of numerous controversies. This paper provides an analysis of published data on elevation differences on sea bottom along the SW margin of the Holy Cross Mts. and in the Cracow-Wielun Upland. Moreover, methods of reconstruction of synsedimentary relief are presented. In the Late Oxfordian the elevations on basin floor in the Czestochowa area (Cracow-Wielun Upland) were about 100 meters at most, and were presumably even lower. The largest (over 200 meters) elevation differences of sea-bottom relief existing in the Czestochowa area at the Oxfordian/Kimmeridgian have been postulated when the recently observed differences in thickness between the deposits of carbonate buildup and of equivalent basinal facies were identified as a relief. In fact, different thickness is, in considerable part, an effect of differential compaction.
Wzrost budowli węglanowych na północnym, stabilnym szelfie Tetydy był główną przyczyną powstania urozmaiconego reliefu dna w basenie późnojurajskim. Rekonstrukcja tego reliefu jest przedmiotem licznych kontrowersji. Praca analizuje dane literaturowe o wielkości deniwelacji dna z rejonu SW-obrzeżenia Gór Świętokrzyskich i Wyżyny Krakowsko-Wieluńskiej oraz omawia metodykę rekonstrukcji reliefu synsedymentacyjnego. Deniwelacje dna basenu u schyłku oksfordu w rejonie Częstochowy wynosiły co najwyżej około 100 m a przypuszczalnie były jeszcze mniejsze. Postulowane wcześniej, ponad dwustumetrowe deniwelacje w basenie w rejonie Częstochowy na przełomie oksfordu i kimerydu były oparte na utożsamianiu z deniwelacjami dna aktualnej różnicy miąższości między utworami budowli węglanowej a ekwiwalentnymi jej utworami facji basenowej. Różnica ta jest w znacznej części wynikiem zróżnicowanej podatności osadów na kompakcję.

The problem of calcium deficiency in the diet of modern man is well known. Calcium deficiency can lead to osteoporosis and frequent bone fractures, rickets, skeletal muscle cramps, thrombosis, hypertension, allergies, and rectal cancer, etc. There is also a shortage of dietary fibre due to excessive refined products. This problem is proposed to be solved by the manufacture of a functional food product-dry-cured sausage, with the addition of biologically active chitin-mineral food supplement “Hizitel” based on dietary fibre.Thefood supplementwasobtained by processing the shell-containing raw materials in the electrolyser. The selected method does not provide for the use of aggressive substances, thereby preserving the native structure of the chitin–mineral complex of the shell. The effect of the concentration of chitin–mineral food supplement in dry-cured sausage on the acidity and solid content in the product has been studied. The optimal concentration of added hizitel has been determined to prolong the shelf life and enrich the product with minerals and vitamins.

This study used an experimental method consisting of 3 storage temperature treatments at 25 ºC, 35 ºC and 45 ºC. Observations carried out include sensory (hedonic) test, water content test, and TBA (Thiobarbituric Acid) test. For the calculation, Arrhenius model was chosen with odor as a critical parameter to determine the shelf life which had the biggest R2 value with equation Arrhenius Ln K = 1079.8 (1/T) – 5.5161, with R2 value equal to 0.9212. The shelf life of catfish skin crackers that was saved at the room temperature (25 ºC) was 39 days or 1.3 month.

Opis:
In 2009, on the initiative of PT Halmahera Perkasa the “Jayapura” exploration project was carried out in Indonesia. As part of this project, exploration of the sea bottom in the northern coast of New Guinea was carried out over a distance of ~45 km. The suction dredge collected 59 samples of loose sediments from the shelf bottom surface of the Carolinian Sea (to a depth of 60 m below the sea-floor). The extracted samples are usually poorly and moderately sorted sands (5 samples), medium-grained sands (21 samples), and fine-grained sands (33 samples). The sand composition shows, among others, a wide spectrum of heavy minerals of ultra-mafic (Cr-garnet, chromium spinel, Mg-olivine) and metamorphic (epidote, clinochlore, amphibole, titanite) origin. The content of heavy minerals in the sediments is up to 54.77 wt.%. It was found that the source of heavy fraction in the eastern and western parts of the coast is the rock of the ophiolite series building the Cyclops Mountains Massif. The mineral composition of sediments from the central coastal zone corresponds to the types of rocks building the metamorphic core of the Cyclops Mountains (amphibolite, gneisses, andesite). Three mineral-geochemical subprovinces were determined on the basis of analyses of heavy mineral decomposition and chemical analyses of sediments. Shelf sediment from the eastern part of the coast is characterized by an increased content of strategic metals (Ni up to 3560, W up to 3130 and Co up to 142 ppm). In the central zone, the V content increases up to 244 ppm and the Ag content up to 5 ppm. In the shelf sediments there is a strong depletion in the REE.

Opis:
The aim of this study was to determine the microbiological stability and changes occurring in selected physicochemical properties of raw pork sausages during hyperbaric storage at subzero temperature (HS-ST). It was shown that storage at moderate pressures (up to 111 MPa) led to a reduction in microbial populations. After 21 days of storage under these conditions, no microorganisms were detected in the samples. Additionally, the inhibition of thiobarbituric acid reactive substance (TBARS) formation was observed under HS-ST conditions. The negative effect of the storage at 111 MPa/−10℃ was the sausage colour change from pink to grey-pink or grey, visible to the naked eye. Such changes did not occur in the samples stored at 60 MPa/−5℃ for 35 days. The results showed that applying HS-ST at 60 MPa/−5℃ allowed the shelf-life of raw pork sausages to be effectively extended by at least 35 days without visible quality deterioration.

Late Jurassic is the key epoch for an idea of the existence of the southeastern segment of the Mid-Polish Trough. New data on the evolution of Upper Jurassic deposits in the Carpathian Foredeep substrate provide information that there is a complete Oxfordian through Valanginian succession in the area of thick Oxfordian and Kimmeridgian deposits, proving the occurrence of the trough. Thickness of the Oxfordian and Kimmeridgian succession is twice to three times smaller than previously assumed. The facies development patterndistinguishes this area from the rest of the Late Jurassic basin. The sponge megafacies ranges up into the lower most Tithonian in this region.Tithonian Štramberk-type reefs occur near the Carpathian thrust front and alongside. The Late Jurassic and earliest Cretaceous facies are latitudinally arranged. Starting from the latest Middle Jurassic, the study area showed strong structural and facies relations to the Tethys do main. The collected data contradict the hypothesis that the Mid-Pol ish Trough continues in the Carpathian Foredeep substrate.

Opis:
The catastrophic mine failure resulting from the inrush of water into the Wapno Salt Mine was probably caused by a fracture in the roof protection shelf. The purpose of the present study was to apply the method of the homogenization of the multi-level room-and-pillar structure in the Wapno Salt Mine for 3D+t modelling of the elastic-viscous medium to determine the distribution of stress and strain, and, on that basis, to estimate the geomechanical conditions existing in the roof shelf. This paper presents briefly the spatial development of the salt mine’s structure and the results of the surveying measurements carried out during the salt mine’s operation and after the mine was flooded. Those results constituted a basis for the verification of the introduced homogenization parameters, i.e. the time-dependent changes of the elasticity modulus and the susceptibility to creep at particular salt mine’s levels. A simulated process demonstrated the development of positive values of principle stresses, increasing with time, and of omnidirectional tensile strains. In such conditions, the cracking of the protection shelf body could proceed, also with opening of water flow paths from the dome cap into the salt mine’s workings. This paper presents a new research method, the results of its application, and the obtained distribution of stresses and strains that can be useful for the assessment of water hazard in other salt mines.
Katastrofa górnicza wywołana wdarciem wody do kopalni soli w Wapnie spowodowana była prawdopodobnie pęknięciem ochronnej półki stropowej. Celem tej pracy było zastosowanie metody homogenizacji struktury komorowo-filarowej wielopoziomowej kopalni Wapno do modelowania ośrodka sprężysto-lepkiego 3D+t dla określenia rozkładu naprężeń i odkształceń oraz na tej podstawie oszacowania warunków geomechanicznych w półce stropowej. W pracy przedstawiono krótko rozwój przestrzenny struktury kopalni oraz wyniki przeprowadzonych pomiarów geodezyjnych w czasie działalności kopalni i po jej zatopieniu. Wyniki te były podstawą do weryfikacji wprowadzanych parametrów homogenizacji, tj. zmian w czasie modułu odkształceń i podatności na pełzanie poszczególnych poziomów kopani. Symulowany proces wykazał wykształcanie się rosnących w czasie dodatnich naprężeń głównych oraz wszechstronnych odkształceń rozciągających. W takich warunkach postępować mogło spękanie calizny półki ochronnej, a także otwieranie dróg przepływu wód z zawodnionej czapy wysadu do wyrobisk. W pracy przedstawiono nową metodę badań, jej wyniki i otrzymane rozkłady naprężeń i odkształceń, która może być zastosowana w ocenie zagrożenia wodnego kopalń soli.

Opis:
The Palaeoproterozoic succession of the Singhbhum craton in E. India was hitherto considered as almost entirely siliciclastic and partly volcanogenic. Here we describe, from the fine-grained, tidally influenced shale facies of the Palaeoproterozoic Chaibasa Formation (2.1-1.6 Ga), a fine, originally more or less horizontal, wavy to strongly undulating (later locally deformed) lamination. Investigation of these laminae shows that they must be ascribed to the accumulation of fine particles on microbial mats that covered a sandy substrate. The structures must therefore be considered as stromatolites, features that are accepted as proof of the presence of micro-organisms, in this case most probably cyanobacteria. The interpretation of biogenic activity is supported by microscopic analysis. It is the first description of traces left by biogenic activity that took place in the Palaeoproterozoic of the Singhbhum craton.

Opis:
A diverse microvertebrate fauna is described from the Virgin Hills and Napier formations, Bugle Gap Limestone Canning Basin, Western Australia. Measured sections at Horse Spring and Casey Falls (Virgin Hills Formation) and South Oscar Range (Napier Formation) comprise proximal to distal slope carbonates ranging in age from the Late Devonian Frasnian to middle Famennian. A total of 18 chondrichthyan taxa are identified based on teeth, including the first record of Thrinacodus tranquillus, Cladoides wildungensis, Protacrodus serra and Lissodus lusavorichi from the Canning Basin. A new species, Diademodus dominicus sp. nov. is also described and provides the first record of this genus outside of Laurussia. In addition, the upper range of Australolepis seddoni has been extended to Late Devonian conodont Zone 11, making it the youngest known occurrence for this species. The Virgin Hills and Napier formations microvertebrate faunas show close affinities to faunas recovered from other areas of Gondwana, including eastern Australia, Iran, Morocco and South China, which is consistent with known conodont and trilobite faunas of the same age.

Opis:
The Middle to early Upper Miocene Machów Formation represents the youngest and little to non-deformed increment in the Carpathian Foredeep Basin that was initiated during the Paleocene in response to thrust loading of the North European craton. The onset of the Machów Formation was associated with the late Badenian (lateMiddle Miocene) flexural subsidence (ca 12.5 Ma BP) that resulted in underfilled-basin conditions recorded in the emplacement of submarine fans and shelf-margin deltas, up to 400 m in relief. These systems were fed from the south by a net of small, suspended-load dominated rivers, which resulted in the strongly heterolithic nature of the basin infill. There is a striking absence of large-scale traction structures, and thick sandstone/mudstone packages intercalated with thick-bedded massive sandstones provide evidence of deposition mainly from sustained turbidity currents typified by oscillations in velocity and sediment concentration within a flow. The evidence in both submarine-fan and delta-front deposits includes the abundance of climbing ripples, thick flat-laminated intervals within the otherwise massive thick-bedded sandstones, and inverse to pensymmetrical grading associated with a succession of structural divisions, which departs from that generated by harmonic energy dissipation typical for surge-type (semi-constant volume) turbidity currents. This evidence is interpreted to reflect deposition mainly from hyperpycnal flows, whose oscillatory behaviour reflected chiefly changing flood stages in the sourcing fluvial flow. The inferred semi-permanent flow feeding is also supported by the very high sedimentation rate (locally up to 24 cm/a) of the Machów Formation. Four clinoform types have been distinguished in the formation. Type 1 is most common and corresponds to platform (“shallow-water”) deltas of subseismic scale. The remaining three are shelf-margin (“deepwater”) deltas. The latter types differ one form another in the height and internal structure of clinoforms, as well as in the degree of downdip segregation of sand that either dominates in slope increments (type 2), forms shingled clinoform toes (type 3), or is concentrated in basin-floor fans in the front of a muddy clinoform slope. The basinward sand segregation is facilitated by the dissection of a clinoform’s top during the maximum fall in relative sea level and by long slopes that ease the transformation of hyperpycnal flows into high-efficiency turbidity currents. Numerous internal onlap unconformities make the shelf-margin deltas interesting targets for hydrocarbon search in stratigraphic traps. The identified type 4 clinoforms, up to 200 m high, in the Quinqueloculina reusii zone point to a major deepening in the upper part of the Machów Formation. This suggests a rise in flexural accommodation at ca 11 Ma BP, and contradicts the common view on uniform upward-shallowing throughout the formation.

Opis:
During the Devonian the sedimentation on the continental shelves of Ardenne Massif and Boulonnais has changed from a mixed siliciclastic-carbonate ramp (Eifelian), through a carbonate barrier reef (Givetian) and then to a detritic influx with local mud-mounds (Frasnian). Here we analysed the faunistic dynamics of the trilobite associations through the changing environment. We used multivariate analyses (clustering and ordering) to discriminate the trilobite associations within 67 different samples. Three previously known communities and one new were recognised: the Eifelian Mixed association, the Givetian Dechenella association and the two Frasnian Bradocryphaeus and Scutellum-Goldius associations. These trilobite faunas present a progressive ecological specialisation. The Mixed association occurs both in the ramp or carbonated (local reef developed on the ramp) facies without any significant difference in its composition. The Dechenella fauna occurs preferentially close to barrier reefs, but can also survive during short periods of detrital input. The two Frasnian communities show a strong relationship with their environment. The Scutellum-Goldius association is only found in reef systems, whereas the Bradocryphaeus flourishes exclusively in lateral facies.

Opis:
During the Rupelian–Chattian, the Qom Basin (northern seaway basin) was located between the Paratethys in the north and the southern Tethyan seaway in the south. The Oligocene deposits (Qom Formation) in the Qom Basin have been interpreted for a reconstruction of environmental conditions during deposition, as well as of the influence of local fault activities and global sea level changes expressed within the basin. We have also investigated connections between the Qom Basin and adjacent basins. Seven microfacies types have been distinguished in the former. These microfacies formed within three major depositional environments, i.e., restricted lagoon, open lagoon and open marine. Strata of the Qom Formation are suggested to have been formed in an open-shelf system. In addition, the deepening and shallowing patterns noted within the microfacies suggest the presence of three third-order sequences in the Bijegan area and two third-order depositional sequences and an incomplete depositional sequence in the Naragh area. Our analysis suggests that, during the Rupelian and Chattian stages, the depositional sequences of the Qom Basin were influenced primarily by local tectonics, while global sea level changes had a greater impact on the southern Tethyan seaway and Paratethys basins. The depositional basins of the Tethyan seaway (southern Tethyan seaway, Paratethys Basin and Qom Basin) were probably related during the Burdigalian to Langhian and early Serravallian.

Opis:
The first appearance of the brachiopod Cyrtospirifer and related forms in the Late Devonian of South China significantly postdates the beginning of the Frasnian and the entry of the group in other parts of the world. Scattered data from different sections suggest that its first entry, associated with the emergence of other plicate spiriferids, such as theodossid and conispiriferid brachiopods, was late in the Middle Frasnian. At the same time, many rhynchonellids disappeared or became extinct locally in South China. This brachiopod faunal overturn near the Palmatolepis punctata–Early Pa. hassi zonal boundary is the most significant event in the Early–Middle Frasnian of South China, characterized by about a 35% loss of existing species and the flourishing of the plicate spiriferids, which was coeval with the end of a major biogeochemical perturbation recently recognized in the Pa. punctata Zone. By contrast, atrypid brachiopods do not seem to show any significant diversity change. The brachiopod faunal change was probably related to a (local?) transgressive event in South China, which also brought new pelagic faunas northwards into some intra−shelf deeper water areas, such as the Shetianqiao area in central Hunan Province. Fifteen brachiopod species are described and illustrated, which include some taxa that are first recorded or recognized in South China, e.g., the spiriferid Pyramidaspirifer, which is now known from both North America and South China. One new species, Desquamatia qiziqiaoensis, is erected.

Opis:
An autochthonous community of benthic diatoms was discovered in June 2015 in the upper sediment layer at depths of 170, 205, and 245 m in the central Barents Sea. At least three benthic microalgae species (Gyrosigma fasciola, Pleurosigma angulatum, and Pleurosigma sp. 1) were detected in the sediment but not the upper water column. Analyses revealed that these benthic microalgae represent a depleted fragment of Arctic littoral microphytobenthos. Compared with the littoral flora, the deep-water assemblage is less diverse and displays low abundance. The data reported here challenge the generally accepted belief that the presence of certain microalgae at significant depths results from vertical or horizontal transfer.

Opis:
Apples, like other fruits, are exposed to stress during their growth and development in the field, also during harvest and the postharvest environment (processing, storage, and transportation). The refrigeration system allows for bulk handling of food products from harvest to market, ensuring that food products are maintained in their freshness and integrity for an extended period through careful management of storage temperature and humidity. This study investigated the effects of storage on the weight loss of apples (Golden Delicious fruits harvested at maturity), under refrigerated conditions at a temperature of 5 ± 0.5°C and relative humidity of 82% and under ambient storage at a temperature of 25 ± 0.5°C and relative humidity of 60%, over 3 months. The findings revealed that the two groups of apples experienced weight reduction at different levels. Apples placed at cold storage presented a loss of weight between 3.31 g and 4.49 g; however, apples stored at ambient temperature showed a significant loss of weight between 21.90 g and 31.76 g.

Wchodzi w obszar profanum. Miejsce nieodgadnione, sacrum, uświęcone przez kontakt z siłami nadprzyrodzonymi, pojawia się wobec tego, co zwykłe, a zarazem codzienne. Sklep, hipermarket traktowany przez wielu jako substytut wewnętrznych potrzeb, zajmuje miejsce obiektu kultu. Jest on dla społeczeństwa konsumentów pewnego rodzaju sacrum. Przewrót znaczeniowy spowodował traktowanie sklepu jako zlaicyzowanego obiektu kultu. Organizowanie przestrzeni strefy promocyjnej hipermarketu charakteryzuje się celowym rozmieszczeniem elementów, zaprojektowanych w myśl odpowiednich wytycznych. Sposób komponowania świątyni ducha (kościoła), czy też ciała (sklepu) cechuje ład, porządek, stosowanie nieskomplikowanych układów brył zgrupowanych i uszeregowanych. Proces projektowania strefy promocyjnej to działania wielowarstwowe, polegające na umiejętności łaczenia niejako na jednym obrazie zagadnień z zakresu wystawiennictwa, aranżacji wnętrz, szeroko rozumianych działań plastycznych, merchandisingu, psychologii konsumenta. Po zsumowaniu detale ekspozycji mają układać się w jeden, sprawnie funkcjonujący organizm naczyń połączonych. Dlatego też istotna jest całościowość koncepcji, łączącej ze sobą wszystkie aspekty omawianych zagadnień.
The space is a critical architectural form. The exhibition space over large retail outlet, understood as the temple of commerce, applicable to several places. These are: promotional zone site, exhibition inside the shop, hot shop, trading post. In the context of the traditional sense of the temple and relation to this subject, it is desacralisation. Enters into the area of the profane. Enters into the area of the profane. Place inscrutable, sacred, sanctified by contact with the supernatural, there is the face of what ordinary, and at the same time every day. Store, hypermarket regarded by many as a substitute for internal needs, takes the place of the object of worship. It is for the consumer society a kind of sacred. The coup caused the semantic treatment of the store as a secularized object of worship. Organizing the promotion zone of hypermarket has a purposeful arrangement of parts, designed in accordance with relevant guidelines. The method of composing the temple of the spirit (church) or body (shop) is characterized the order, the use of simple circuits blocks grouped and prioritized. The process of designing a promotional zone is a multi-activity, involving the skills of joining it were a single image issues of exhibitions, interior design, broadly understood artistic activities, merchandising, consumer psychology. After summing up the details of exposure they have to fall into one smoothly functioning system of connected vessels. Therefore, it is important to the concept of wholeness, linking together all aspects of the issues discussed.

Opis:
Fotogrametria z lotniczych platform bezzałogowych rozumiana jako nowe narzędzie do wykonywania pomiarów łączy możliwości wykonywania pomiarów fotogrametrycznych naziemnych, lotniczych, a nawet suborbitalnych, stanowiąc jednocześnie niskobudżetową konkurencję dla klasycznej fotogrametrii lotniczej czy teledetekcji satelitarnej. W pracy przedstawiono podstawy budowy bezzałogowego statku powietrznego przeznaczonego do lotów fotogrametrycznych (teledetekcyjnych), analizę preferowanego rodzaju platformy oraz przegląd komercyjnie dostępnych komponentów i elementów systemu. Jak pokazują wyniki przedstawionej analizy, preferowaną platformą do wykonywania lotów fotogrametrycznych z ukierunkowaniem na pomiar maksymalnie dużych powierzchni jest szybowiec z napędem elektrycznym. Platforma tego typu charakteryzuje się większą odpornością na działanie wiatru oraz pozwala wykonywać długotrwały lot, w przeciwieństwie do platform typu wielowirnikowiec.
A photogrammetry from an unmanned aerial vehicle (UAV) can be understood as a new measurement tool. It introduces low-cost alternatives for a traditional aerial photogrammetry, combining terrestrial, aerial, and satellite photogrammetry techniques. This paper presents a photogrammetric UAV construction basics, a recommended platform analysis, and a review of commercially available components and systems’ elements designed for photogrammetric UAV purposes. As the results show, a motoglider can be recommended as a platform for a photogrammetric task, where the priority is to execute the maximum area coverage during one flight. That platform type is resistant to windy conditions and is able to execute long flight, opposite to multirotor platforms.

Opis:
The problem considered in this paper is the derivation of properties of edge waves travelling along a submerged horizontal shelf. The problem is formulated within the framework of the linearized theory of water waves and Havelock expansions of water wave potentials are used in the mathematical analysis to obtain the dispersion relation for edge waves in terms of an integral. Appropriate multi-term Galerkin approximations involving ultra spherical Gegenbauer polynomials are utilized to obtain a very accurate numerical estimate for the integral and hence to derive the properties of edge waves over a shelf. The numerical results are illustrated in a table and curves are presented showing the variation of frequency of the edge waves with the width of the shelf.

Opis:
The purpose of this research is to determine the effectiveness of turmeric and its best concentration in preserving the presto of lalawak fish based on the characteristics of microbiological tests and chemical tests including checking water content and pH. The research experimental method covered five treatments by adding turmeric extract solutions of 0%, 1%, 3%, 5%, and 7%. The test parameters observed in the research were microbiological tests using the method of TPC (Total Plate Count) in duplicate and chemical tests including checking water content and pH. The results showed that all treatments by adding turmeric extract were with concentrations of 1%, 3%, 5%, and 7% able to extend the shelf life presto of lalawak fish more than two days compared to the presto of lalawak fish which were not treated with turmeric extract or control (0%) which can only last two days. The treatment of the addition of 5% turmeric extract is able to provide the long lasting strength of lalawak fish for up to five days so that the shelf life is longer than other treatments, as evidenced by the TPC (Total Plate Count) value of 5.81×105 CFU / gram on the 6th day. The water content reached 67.5% on the 6th day and the pH value reached 6.50 on the 5th day.

Opis:
Observations of the shelf environment rarely associate internal solitary waves (ISWs) with the impact of their passage. An experiment observed during the Coastal Mixing and Optics 1996( CMO ’96), a sequence of long internal waves on a coastal shelf is reported, including both mode-1 and mode-2 waves, together with evidence related to the interaction of propagating ISWs and the benthic boundary layer. The observed ISW dynamics is shown to present a repetitive pattern or ‘climate cycle’. The ISW-associated benthic signature described here occurs frequently (at least once a day) in the CMO ’96coastal area and suggests that ISWs under calm, summer-like conditions may have a decisive influence on the fate of near-bottom pollutants or biological processes in shelf regions.

Opis:
The main findings of studies of the physical oceanography of the Gulf of Finland (GoF) during 1997–2007 are reviewed. The aim is to discuss relevant updates published in international peer-reviewed research papers and monographs, bearing in mind that a comprehensive overview of the studies up to the mid-1990s is available (Alenius et al. 1998). We start the discussion with updates on the basic hydrographical and stratification conditions, and progress in the understanding of atmospheric forcing and air-sea interaction. Advances in the knowledge of basinscale and mesoscale dynamics are summarised next. Progress in circulation and water exchange dynamics has been achieved mostly by means of numerical studies. While the basic properties of circulation patterns in the gulf have been known for a century, new characteristics and tools such as water age, renewal index, and high-resolution simulations have substantially enriched our knowledge of processes in the Gulf of Finland during the last decade. We present the first overview of both status and advances in optical studies in this area. Awareness in this discipline has been significantly improved as a result of in situ measurements. Our understanding of the short- and long-term behaviour of the sea level as well as knowledge of the properties of both naturally and anthropogenically induced surface waves have expanded considerably during these ten years. Developments in understanding the ice conditions of the Gulf of Finland complete the overview, together with a short discussion of the gulf’s future, including the response to climate change. Suggestions for future work are outlined.
