Opis:
Wzrost zainteresowania żywnością tradycyjną i regionalną wpisuje się w nowe trendy zachowań konsumentów na rynku żywności. Jednak zagadnienie postaw polskich konsumentów w stosunku do żywności tradycyjnej i regionalnej, jak wynika z analizy literatury przedmiotu, nie było dotychczas przedmiotem zbyt wielu badań. Celem zrealizowanych badań było określenie czynników determinujących zachowania polskich konsumentów na rynku żywności tradycyjnej. Zakres pracy obejmował określenie: sposobu definiowania terminu „żywność tradycyjna i regionalna” przez polskich konsumentów, motywów zakupu żywności tradycyjnej i regionalnej, dostępności informacji o tej żywności, preferencji konsumentów w zakresie asortymentu, cen i miejsc zakupu tej kategorii żywności. Dokonano również ogólnej charakterystyki konsumentów deklarujących zakup żywności tradycyjnej i regionalnej. Badania przeprowadzono metodą wywiadów bezpośrednich, z wykorzystaniem kwestionariusza wywiadu, na populacji 150 mieszkańców Warszawy i okolic w czerwcu i lipcu 2007 roku. Spośród badanych konsumentów, aż 78 % zadeklarowało, że kupuje żywność tradycyjną i regionalną. Zdecydowana większość respondentów przypisała żywności tradycyjnej i regionalnej atrybuty takie, jak „zdrowa”, „mniej przetworzona” oraz „smaczna”. Pozwala to na stwierdzenie, że żywność tradycyjna i regionalna postrzegana jest w sposób pozytywny, a szczególne znaczenie mają jej walory smakowe. To z kolei znajduje odzwierciedlenie w hierarchii czynników wpływających na decyzję o zakupie tego typu żywności. Respondenci przyznali, że lubią próbować potrawy charakterystyczne dla danego regionu, gdyż odpowiada im smak i zapach tych produktów. W mniejszym stopniu o wyborze tego typu żywności decydują walory odżywcze i przekonanie o jej pozytywnym wpływie na zdrowie. Badani, którzy nie kupują żywności tradycyjnej za główny powód podają problem z dostępnością tej kategorii żywności (62 %) oraz za wysoką cenę (41 %). Wśród innych czynników wpływających na decyzję o zakupie wymieniono: brak wiedzy na temat tego typu produktów i miejsc ich sprzedaży oraz brak umiejętności odróżnienia żywności tradycyjnej od innych produktów żywnościowych. Zarówno ograniczona dostępność, mało zróżnicowany asortyment, jak i zbyt wysoki, w opinii badanych konsumentów, poziom cen żywności tradycyjnej stanowią potencjalną barierę rozwoju popytu na tę kategorię żywności. Dalszy rozwój rynku żywności tradycyjnej i regionalnej wymaga więc opracowania strategii rozwoju tego segmentu rynku żywności.
The increase in interest in the traditional and regional food has become a part of new trends in the behaviours of consumers in food market. However, the analysis of reference literature shows that, until now, not too many studies had the objective focused on the attitudes of Polish consumers to traditional and regional products. The objective of the research accomplished was to determine the factors determining behaviours of the consumers in the traditional food market. The scope of the research included the determination of the following: method used by the Polish consumers to define the term „traditional and regional food”; motives of purchasing traditional and regional food; accessibility of information on this food; consumers’ preferences in the range of assortment, prices, and places of purchasing food under this category. Moreover, a general characterization of the consumers declaring that they purchased traditional and regional food was provided. In the research, a method of direct interviews was applied with the use of questionnaires. The polled group consisted of 150 residents of Warsaw and of its environs; the interviews were performed in June and July 2006. As much as 78 % of respondents admitted they bought the traditional and regional food. The unquestionable majority of respondents attributed such qualities as „healthful”, „less processed”, and „tasty” to the traditional and regional food. Therefore, it can be concluded that the traditional and regional food is perceived in a positive way and its taste qualities are of special significance. This in turn is reflected in the hierarchy of factors impacting the decision whether or not to buy this type of food. The respondents admitted they liked trying products characteristic of a given region, since their taste and savour suited them. Nutritional values of this food and the belief of the consumers about its positive impact on their health are critical to them to a lesser extent critical when they choose those products. The polled, who do not buy the traditional food, explain that the main reasons thereof are: those products are hard to get (62 %) and their prices are too high (41 %). Among other factors impacting the purchase decision, the following were named: lack of knowledge of such products; lack of information on places where they are sold; inability to distinguish between the traditional and other food products. Both the limited accessibility and the low diversification of the assortment, as well as, in the opinion of the polled, the too high level of prices of the traditional food constitute a potential barrier to the development of demand for food under this category. Thus, for the purpose of further development of the traditional and regional food market, it is necessary to work out a developmental strategy of this market segment.

Opis:
The purpose of this paper is to prove that near infrared radiation (NIR) modifies hydrogen bonds localized in the interface of reversed micelles. The degree of modification of the hydrogen bonds was monitored by TEMPO-palmitate spin probe introduced into the structure of reverse micelles formed by cetyltrimethylammonium bromide (CTAB) (TCAB/phosphate buffer/isooctane/hexanol and TCAB/NaCl/isooctane/hexanol (W = 15)). Electron paramagnetic resonance (EPR) spectra were performed on the argonated samples. The isotropic tumbling correlation time (τc) and the hyperfine coupling constant A+ = h0 – h+1 (h+1, and h0 correspond to the low-, and centre-field lines, respectively) were determined from the EPR spectra as a quantitative measure for monitoring the action of NIR radiation. A+ values depend on the composition of the water pool (1.640 mT for phosphate buffer and 1.630 mT for NaCl). NIR irradiation led to decrease in A+. This parameter reached the same value for both solutions (1.625 ± 0.003 and 1.626 ± 0.003 mT) after exposition to NIR. The tumbling correlation time after exposure to NIR decreased for TCAB/phosphate buffer/ isooctane/hexanol reversed micelles from 2.10 × 10–10 s to 1.44 × 10–10 s but did not change for TCAB/NaCl/isooctane/ hexanol). The results obtained confirm the possibility of modification of the hydrogen bonds by NIR radiation.

Opis:
The progressive degradation of soils is a recently increasing environmental problem. The risk of soil degradation may be associated, for example, with landslides, flooding, soil erosion. However, these are relatively rare phenomena compared to the risk of chemical degradation caused by human activity. Given the limited research on the positive effect of miscanthus biochar on soil properties, a study was carried out aimed at determining changes in pH, electrical conductivity, sorption properties, and mobility of selected heavy metals in sandy soil treated with various chemicals. Biochar used in the study was produced at a temperature of 300°C. The addition of biochar to soil generally increased the pH value, regardless of the type of chemical degradation. The study revealed a decrease in the hydrolytic acidity value and, at the same time, no significant changes in the content of alkaline cations and sorption capacity of the biochar-treated soil. The best effect on reducing the mobility of trace elements was achieved by adding biochar to the soil supplemented with acidifying substances. Bearing in mind the current agricultural and environmental problems, there is a need to increase the effectiveness of biochar and to direct its action to improve specific soil properties.

Opis:
Radiocarbon dating applied on several occasions in the past to date animal bones and animal soft tissue originating from the area of the Starunia palaeontological site turned out to be very controversial. Although investigations of Pleistocene flora in the Starunia area go back to the beginning of the 20th century, no published 14C dates of such material are available to date. Sixteen boreholes drilled in the area of the Pleistocene mammals discoveries, in the framework of a multidisciplinary research project (2006-2009), have been selected for radiocarbon dating of plant macrofossils. Moreover, five samples of plant remnants extracted from two outcrops in the area were 14C-dated. The nature of the dated plant material, in some cases soaked with oil, posed specific methodological problems. Although applied chemical treatment of macrofossil samples led to complete removal of contaminating hydrocarbons in the case of small pieces, some ageing effects in terms of radiocarbon dating cannot be completely ruled out. Radiocarbon ages of macrofossil samples originating from the close neighbourhood of the location, where the "second" woolly rhinoceros was found at a depth of 12.5 m, suggest that the minimum age of sediments in which the Pleistocene mammals were found is in the range of ca. 35-40 ka BP. A broad consistency between palynological reconstruction of Younger Dryas/Preboreal boundary and the corresponding radiocarbon ages of macrofossils is observed for locations, where the natural sedimentary sequence for late Glacial and early Holocene was not disturbed by extensive mining activity in the area.

Opis:
The flux and isotopic composition of soil CO2 has been monitored at three sites located in the southern Poland, during the time period: January 1998 - December 2000. The sites represent typical ecosystems appearing in central Europe: mixed forest, cultivated agricultural field and grassland. To monitor the flux and isotopic composition of soil CO2, the method based on the inverted cup principle was used. The flux of soil CO2 reveals distinct seasonal fluctuations, with maximum values up to ca. 20 mmolźm-2 h-1 during summer and around ten times lower values during winter. Also significant differences among the monitored sites were detected, the CO2 flux being the highest for the mixed forest site and ca. two times lower for the grassland site. The 13C content of the soil CO2 flux is nearly constant throughout the year, with d13C values essentially reflecting the isotopic composition of the soil organic matter and the vegetation type. The 18O content of the soil CO2 flux shows a remarkable seasonality, with distinctly less negative d18O values recorded during summer. This seasonality is highly reduced in the CO2 sampled from different depths of the soil. The radiocarbon content of the CO2 flux turned out to be non-distinguishable, within the uncertainty of the measurements, from current 14C levels in atmospheric carbon dioxide. However, significant reduction of the radiocarbon content was measured in the soil CO2 sampled at 80 cm, when compared to the uppermost layer, reflecting increasing age of soil organic matter with depth.

Opis:
Denitrification is the only process leading to reduction of nitrate concentration in groundwater. In this paper the authors report the results of combined measurements of excess gaseous nitrogen and 18O and 15N isotope composition of dissolved nitrate in fissured-karstic Triassic aquifer located in southwestern Poland, in the vicinity of Opole. Generally, the wells located in the confined part of the aquifer reveal greatly reduced nitrate content (ca. 0.3 and 2.7 mg NO3/dm3). Such decrease of nitrate content together with δ18O and δ15N data for those wells suggest well-advanced denitrification process. Enrichment in 15N and 18O of the remaining nitrate corresponds to initial nitrate content in the order of 1.5 to 12 mg NO3/dm3. Lack of tritium in those wells suggest the pre-bomb age of water and natural range of initial nitrate content. In majority of the measured wells nitrogen excess has been below the detection limit of ca. 3.5 mg NO3/dm3. This method is not sensitive enough to detect denitrification of natural nitrate which concentrations in groundwater in the study area were generally below 10 mg NO3/dm3. The presented study demonstrated that combining isotope analyses of nitrates with tritium or other transient tracers may provide additional insights into the dynamics of water and nitrate transformation in groundwater systems.

The influence of the process temperature from 85°C to 95°C, the content of phosphates and sulphates in the wet process phosphoric acid (about 22-36 wt% P2O5 and about 2-9 wt% SO42-) and the addition of ?CaSO4ź0.5H2O crystallization nuclei (from 10% to 50% in relation to CaSO4ź2H2O) on the transformation of calcium sulphate dihydrate to hemihydrate has been determined. The wet process phosphoric acid and phosphogypsum from the industrial plant was utilized. They were produced by reacting sulphuric acid with phosphate rock (Tunisia) in the DH-process. The X-ray diffraction analysis was used to determine the phase composition and fractions of various forms of calcium sulphates in the samples and the degree of conversion of CaSO4ź2H2O to ?CaSO4ź0.5H2O and CaSO4. It was found that the transformation of CaSO4ź2H2O to ?CaSO4ź0.5H2O should be carried out in the presence of ?CaSO4ź0.5H2O crystallization nuclei as an additive (in the amount of 20% in relation to CaSO4ź2H2O), at temperatures 90š2°C, in the wet process phosphoric acid containing the sulphates and phosphates in the range of 4š1 wt% and 27š1 wt%, respectively.

Opis:
Two methods of sample preparation for isotopic analyses of nitrates dissolved in water are presented: (i) chemical conversion of NO3– to N2 and CO2, and (ii) bacterial reduction of NO3– to N2O, followed by the measurement of nitrogen and oxygen isotope composition of these gases. Both methods have been successfully used for routine isotope analyses of dissolved nitrates in different types of water. The chemical conversion method, requiring ca. 300 mi mol of NO3– yields relatively good precision, in the order of 0.3‰ for delta15N, and 0.6‰ for delta18 O. The bacterial reduction method was modified in this study to accommodate samples of intermediate size (ca. 30 mmol of NO3–) to provide sufficient amount of N2O gas for isotope analysis using conventional IRMS. The method demonstrated satisfactory results, although sample preparation was more complicated and required access to microbiological laboratory.

Opis:
A key problem to be solved during designing productive diode lasers and their lasing arrays is their proper thermal management enabling efficient high-power operation. Strictly speaking, the above demand leads to optimization of their structures to enhance lasing performance for high operation currents. It is well-known that deterioration of laser performance is mostly induced by excessive temperature increases within their volumes. In diode-laser arrays, additionally thermal crosstalk between array emitters should be taken into account. In the present paper, physics of heat-flux generation within the laser-diode volume and its extraction from it is analysed and described with the aid of our self-consistent simulation procedure. Then their thermal optimization is discussed including a proper design of a heat-flux generation within the laser volume, enhancement of its transport towards a laser heat-sink and, additionally in laser arrays, reduction of a thermal crosstalk between individual array emitters. The analysis is carried out using modern nitride edge-emitting ridge-waveguide lasers and their one-dimensional arrays as well as arsenide semiconductor disk lasers as typical examples of modern diode-laser designs. Physical processes responsible for heat-flux generation within these devices and heat-flux extraction from their volumes are analysed and an impact of some construction details on these processes is explained.

Using the same methodology, apparent hot deformation activation energy Qp and Qss values were calculated for each alloy based on peak stress and steady-state stress values. Linear dependence between quantities Qp and Qss was found, while Qp values are on average only about 6% higher. This should not be essential in predicting true stress of a specific material depending on the temperature-compensated strain rate and strain.

This paper presents the results of a numerical analysis of nitride-based edge-emitting lasers with an InGaN/GaN active region designed for continuous wave room temperature emission of green and blue light. The main goal was to investigate whether the indium thin oxide (ITO) layer can serve as an effective optical confinement improving operation of these devices. Simulations were performed with the aid of a self-consistent thermal-electrical-optical model. Results obtained for green- and blue-emitting lasers were compared. The ITO layer in the p-type cladding was found to effectively help confine the laser mode in the active regions of the devices and to decrease the threshold current density.

Opis:
As part of the tasks performed by the Polish Geological Survey (Polish Geological Institute - National Research Institute), 260 prospective maps (MOP) at a scale of 1 : 200,000 have been developed in the period of 2013-2015. These maps were designed for metal ores (Cu-Ag, Zn-Pb, Mo-W, Ni, Sn, Au, Pt, Pd and Zn oxide ore - galmans) and chemical raw materials (rock and potash salts, gypsum, anhydrite and native sulphur), in relation to the assessment of raw materials resources and environmental restrictions and land use planning. The total surface of prospective teritories projected onto the surface area is ~15.25 thousand km2 for metal ores and ca. 52.5 thousand km2 for chemical raw materials. The estimated resources of predicted ore deposits (prognostic and prospective) are approx. 42.2 million Mg of Cu and 75 thousands Mg of Ag (12 prospective areas), ca. 20 million Mg of Zn-Pb ores (in 4 prospective areas), 32 million Mg of Ni ores of weathering type (10 prospective areas), from 9.4 to 21.5 Mg of Au encountered by orogenic vein and metasomatic deposits (7 prospective areas), and ca. 22 million Mg of Sn ores. The estimated prognostic and prospective resources of chemical raw materials (at a depth of not more than 2000 m) are: ca. 4.059 trillion Mg of rock salt (68 prospective areas) and ca. 3638.1 million Mg of potash (12 prospective areas), as well as ca. 575.6 billion Mg of gypsum and anhydrite, and 202 million Mg of native sulphur (prognostic resources). In the assessment of environmental conflicts and land use planning, 125 information data sheets developed environmental conditions for prospective areas (with the exception of rock salts, which are discussed in the regional aspect). Development of the designated prospective areas may be important in the future to ensure the availability of raw material safety, not only for Poland, but also for the European Union, thus contributing positively to economic growth and prosperity of local communities.
