Opis:
During a survey on fungi associated with decline symptoms on grapevine cultivars growing in Kurdistan region of Iraq, several isolates of Botryosphaeria species were encountered. All isolates were identified as Botryosphaeria parva Pennycook and Samuels. Pathogenicity test for isolate DKI 1 was performed on two cultivars, Taefi and Rashmew. Under greenhouse conditions, one-year grape rooted cuttings were inoculated with the pathogen isolate by two methods, injecting the spore suspension into the green shoots and by artificial inoculation of wounded shoots with mycelial mat. The highest canker length (15.0 mm) was produced after four months on the shoots of the Taife cultivar artificially inoculated with mycelial mat of the pathogen. Under field conditions, two methods of inoculation were adopted, wounding the green shoots and drilling a hole in the arms of mature vine, followed by inoculation with mycelial mat. The highest canker length (11.17 mm) was obtained after 5 months on wounded shoots of the Rashmew cultivar and with a significant difference from the Taefi cultivar. The pathogen caused a reduction in fresh and dry weight of green shoots and roots compared with the non-inoculated control. This is the first report on B. parva in Iraq.
W trakcie prowadzenia badań nad grzybami związanymi z symptomami zamierania gatunków winorośli rosnących w regionie Kurdystan w Iraku natrafiono na kilka izolatów gatunków z rodzaju Botryosphaeria. Wszystkie izolaty oznaczono jako Botryosphaeria parva Pennycook i Samuels. Na dwóch odmianach, ‘Taefi’ i ‘Rashmew’, wykonano test patogeniczności dla izolatu DKI 1. W warunkach szklarniowych jednoroczne ukorzenione sadzonki winorośli inokulowano izolatem patogena przy użyciu dwóch metod: wstrzykując zawiesinę zarodników grzyba w zielone pędy oraz poprzez sztuczną inokulację naciętych pędów za pomocą grzybni. Nekroza o największej długości (15,0 mm) powstała po czterech miesiącach na pędach odmiany Taife sztucznie inokulowanych grzybnią patogena. W warunkach polowych przyjęto dwie metody inokulacji: nacięcie zielonych pędów oraz wywiercenie dziurki w gałęziach dojrzałej winorośli, po czym dokonano inokulacji grzybnią. Nekrozę o największej długości (11,17 mm) uzyskano po 5 miesiącach na naciętych pędach odmiany Rashmew, przy czym różnica w stosunku do odmiany Taefi była istotna. Patogen spowodował zmniejszenie świeżej i suchej masy pędów zielonych i korzeni w porównaniu z nieokulowaną kontrolą. Jest to pierwsze doniesienie na temat grzyba B. parva w Iraku.

Opis:
The article talks about the stereotypes of national character, formed both in own minds and imported from other nations, about how, in the light of these stereotypes, cultural and behavioral consciousness of nation’s immediate, close and distant neighbors are perceived. The author identifies and amplifies the comic symptoms and character traits that are a stable component of such stereotypes and rarely have anything to do with reality. At the same time, the author draws attention to the importance of studying these distorting mirror “portraits” for better understanding of the true national characters, and the treatment of defined states by the international community. Also he identifies the colorful and comic stereotypes such as the images of Uncle Sam – American, Ivan – Russian, Han – the grandfather of Chinese, Kerim – Kazakh, Tashmataka – Uzbek and other folklore characters, actively utilized in various political disagreements, debates and conflicts.

Opis:
Background: For many logistics service providers and shippers sustainable transport is still a relatively recent issue, even if almost every transportation company is engaged in sustainability. Each has had different experiences with making transportation more sustainable. By looking at the efforts and successes of others sharing these experiences could help shippers and logistics service providers to obtain new innovative ideas of how to become more sustainable. The certification organization Green Freight Europe (GFE) wants to develop a database for these types of experiences in order to encourage its members to generate sustainable initiatives. Method: In support of this plan, we interviewed several logistics service providers and shippers and conducted a brief survey among GFE members. Results: Sustainability forms one of the goals for all interviewed companies mainly based on cost reduction but followed closely as a tool to attract new customers. At the moment, the information obtained to keep updated on sustainability comes mainly from truck producers and not from information from best cases from other logistics service providers. Conclusions: We have found that there is a willingness to submit best cases, but also a fear that the submitter will miss his competitive advantage by telling others about his innovations.
Wstęp: Dla wiele dostarczycieli usług logistycznych oraz przewoźników pojęcie transportu zrównoważonego jest pojęciem całkiem nowym, nawet biorąc pod uwagę, że większość fakt, że większość firm transportowych jest już włączonych w rozwój zrównoważony. Każdy z nich ma też inne doświadczenia w tym zakresie. Obserwując wysiłki i osiągnięcia, wydaje się korzystnie dzielenie się swoimi doświadczeniami, które mogą się przyczynić do wprowadzenia nowych innowacyjnych metod prowadzących do zrównoważonego rozwoju firm. Certyfikowana organizacja Green Freight Europe (GFE) chce stworzyć bazę danych obejmujących różnego rodzaju doświadczenia w celu wspierania swoich członków do bardziej zrównoważonego rozwoju. Metoda: przeprowadzono wywiady z dostarczycielami usług logistycznych oraz przewoźnikami jak również przeprowadzono krótką ankietę wśród członków GFE. Wyniki: Rozwój zrównoważony kojarzy się praktycznie wszystkim ankietowanym przedsiębiorstwom z redukcją kosztów, ale również z narzędziem mogącym przyciągnąć nowych klientów. Obecnie otrzymane informacje o podtrzymywaniu praktyk rozwoju zrównoważonego pochodzą głównie od producentów samochodów a nie od dostarczycieli usług logistycznych. Wnioski: Stwierdzono, że istnieje chęć dzielenia się dobrymi praktykami, ale również obawa, że przekazujący informację straci swoją przewagę konkurencyjną poprzez przekazanie innych informacji o unowocześnieniach.

Opis:
The association between physiologically dependent pharmacokinetic parameters (CLB, T1/2β, Vdss) of marbofloxacin and body weight was studied in eight animal species based on allometric equation Y = aWb, where ‘Y’ is the pharmacokinetic parameter, ‘W’ is body weight, ‘a’ is allometric coefficient (intercept) and ‘b’ is the exponent that describes relation between pharmacokinetic parameter and body weight. The body clearance of marbofloxacin has shown significant (P<0.0001) relation with size (Bwt) in various animal species. However, half-life and volume of distribution were not in association with body weight. Although half-life and volume of distribution were not in a good correlation with body weight, statistically significant association between the body clearance and body weight suggests validity of allometric scaling for predicting pharmacokinetic parameters of marbofloxacin in animal species that have not been studied yet. However further study considering large sample size and other parameters influencing pharmacokinetics of marbofloxacin is recommended.

Opis:
A description and analysis is given of three Neogene odontocete caudal vertebrae that were bitten by the extinct megatooth sharks Carcharocles megalodon or Carcharocles chubutensis. The peduncular caudal vertebrae show bilateral gouge marks consistent with having been actively bitten and wedged between adjacent teeth of C. megalodon or C. chubutensis. None of the vertebrae show signs of healing. The occurrence of bite marks on distal caudals suggests active predation (vs. scavenging) in order to immobilize even relatively small prey prior to consumption.

Ca$\text{}_{x}$Fe$\text{}_{3-x}$O$\text{}_{4}$ samples, with x ≤ 0.28 , prepared from α-Fe$\text{}_{2}$O$\text{}_{3}$ and CaO by the Bridgman method were investigated by means of $\text{}^{57}$Fe Mössbauer spectroscopy. Room temperature spectra gave evidence that the samples were multiphase, the calciomagnetite being the dominant phase with a contribution of 73% to 99%, depending on the sample. Analysis of the subspectra associated with the calciomagnetite gave evidence that Ca-ions reside on the tetrahedral (A) sites and have not random distribution. Their presence on those sites causes a reduction of the hyperfine field at Fe nuclei occupying the octahedral positions (B) by 12.3(1.0) kOe per one Ca-ion and a decrease in the average hf field, 〈H$\text{}_{B}$〉/dx, at the rate of 29 kOe/mol% for x ≤ 0.07 and of 387 kOe/mol% for larger x. In addition, a linear correlation between 〈H$\text{}_{B}$〉 and the average isomer shift, 〈I$\text{}_{B}$〉, was revealed to hold. It indicates that addition of Ca-ions into the magnetite causes a decrease in the spin-density and an increase in the charge-density at Fe nuclei occupying the B-sites.

Opis:
W artykule opisano X Walne Zgromadzenie Stowarzyszenia Elektryków Polskich z lipca 1938 roku. To ewenement w historii polskiego środowiska technicznego okresu międzywojennego. Pomysł zrealizowania zjazdu połączonego z wycieczką do Szwecji na transatlantyku m/s „Piłsudski” był na tyle niekonwencjonalny i obarczony ryzykiem, że od samego początku napotykał na wiele głosów krytycznych. Przygotowania do X WZ SEP trwały prawie 2 lata przy ogromnym zaangażowaniu osobistym członków Zarządu Głównego SEP m.in. Alfonsa Hoffmanna i Kazimierza Szpotańskiego. Zjazd zarówno pod względem organizacyjnym jak i towarzyskim wypadł doskonale. Niestety koncepcja urządzania podobnych imprez co 20 lat nie doczekała się realizacji.
The article describes the X General Assembly of the Polish Electrical Engineers Association in July 1938 year. It is unique in the history of Polish technical environment interwar period. The idea to realize the assembly combined with a trip to Sweden on the liner m/s "Pilsudski" was so unconventional and subject to the risk that from the very beginning it faced a lot of criticism. Preparations for the X GA lasted almost two years at a huge personal commitment of the members of the Board of the SEP among others Alfons Hoffmann and Kazimierz Szpotański. Congress both in terms of organization and social proceeded perfectly. The concept of arranging similar events every 20 years has never been realized.

In order to develop management strategies for sustainable use and conservation in the marine environment, reliable and meaningful, but integrated ecological information is needed. Biological valuation maps that compile and summarize all available biological and ecological information for a study area, and that allocate an overall biological value to subzones, can be used as baseline maps for future spatial planning at sea. This paper provides a concept for marine biological valuation which is based on a literature review of existing valuation criteria and the consensus reached by a discussion group of experts.

Opis:
Quail-thrushes (Passeriformes: Cinclosomatidae: Cinclosoma) are ground-dwelling corvoid songbirds endemic to Austra lia and New Guinea. Until now, the only known quail-thrush fossils have been from late Quaternary cave deposits in Australia. A new species of quail-thrush, Cinclosoma elachum sp. nov., is described from the early to middle Miocene deposits in the Riversleigh World Heritage Area, Queensland, Australia. A second, larger quail-thrush is identified from the middle Miocene of Riversleigh. The new fossils considerably extend the geographic and temporal ranges of cinclosomatids, and indicate the presence of two species of quail-thrushes in the Miocene of northern Australia, located more than 300 km from the nearest extant member of Cinclosoma. These fossils provide a minimum age of ~18 million years for Cinclosomatidae. They cannot be confidently assigned to the crown group of the genus Cinclosoma, but can be used to calibrate the split between this genus and Ptilorrhoa in molecular dating studies of the Corvides radiation and Passeriformes overall. This material also adds to the growing diversity of songbirds identified from the pre-Pleistocene record of Australia, and reemphasises the global significance of the Riversleigh deposits in developing understanding about the early evolutionary history of passerines.

The aim of the essay is to demonstrate that John Maxwell Coetzee’s Life and Times of Michael K can be perceived as a parody of Voltaire’s Candide, a novel intended as a ridicule of Leibniz’s Theodicy. While Voltaire proposed to withdraw from the world and ‘‘to cultivate one’s own garden” as a remedy to Leibniz’s ill-conceived optimism, Coetzee shows that Voltaire’s praise of passivity and life in accordance with nature, symbolized by a retreat into gardening, is as erratic as Leibniz’s philosophy. The essay concludes that Coetzee’s Michael K can be treated as a caricature of Voltaire’s Candide.

Gallium nitride bulk crystals grown at about 15 kbar and 1500 K have been examined by using the high resolution X-ray diffractometry. An analysis of a set of the rocking curves of various Bragg reflections enabled us to estimate a dislocation density. For the crystals of dimensions lower than about 1 mm it is lower than 10$\text{}^{-5}$ cm$\text{}^{-2}$. For bigger samples the crystallographic quality worsens. With an application of the reciprocal lattice mapping we could distinguish between internal strains and mosaicity which are both present in these crystals The results for the bulk crystals are compared with those for epitaxial layers.

Opis:
By establishing the bioerosion ichnogenus Oichnus, Richard Bromley (1981) addressed ‘small round holes in shells’ and catalysed a series of still ongoing discussions on ichnotaxonomical principles. In a recent revision by Zonneveld and Gingras (2014), Oichnus was rejected, together with Tremichnus Brett, 1985 and Fossichnus Nielsen, Nielsen and Bromley, 2003, by means of subjective synonymisation with the presumed senior synonym Sedilichnus Müller, 1977. However, Sedilichnus is nomenclaturally unavailable, because it is an atelonym (conditionally proposed). In addition, reinvestigation of the type material of ‘Sedilichnus’ shows that it probably describes variably shaped oscula and thus is a genuine morphological character of the host sponge Prokaliapsisjanus, rather than a bioerosion trace fossil. The ichnogenera Oichnus and Tremichnus are re vised, leading to the synonymisation of Balticapunctum Rozhnov, 1989 with Tremichnus, and of Fossichnus with Oichnus. The refined ichnogeneric diagnoses return Oichnus to complete or incomplete bioerosive penetrations in calcareous skeletal substrates, commonly interpreted as praedichnia with or without signs of attachment, while Tremichnus (now including O. excavatus) exclusively refers to shallow pits passing into echinoderm skeletons that are interpreted as domichnia or fixichnia.

Opis:
The aim of this paper is the study of porous Si prepared by preferential anodic dissolution in concentrated HF acid solutions. Porous silicon layers exhibited extremely efficient luminescence in the 700-900 nm range at room temperature. Basic characteristics of this luminescence strongly suggest the intrinsic origin of the process, directly related to quantum confinement. The additional transmission-electron-microscopy and electron-diffraction studies - were performed to support hypothesis that luminescence originates from silicon nanostructures.

Opis:
Summertime (2009), the third book of J.M. Coetzee’s autobiographical trilogy, is more poetic and more nostalgic in its depiction of South Africa than the writer’s previous works, though his vision remains sharp and unsentimental. Written from the perspective of an émigré writer, Summertime is an imaginative mapping of personal memories that reside in various places of South Africa, especially in the ruggedly beautiful landscapes of the Karoo region. For Coetzee, the Karoo is the site of the individual and collective historical past which he attempts to reconstruct and retain. The open spaces of the Karoo provide inspiration for his art and stimulate his search for new expressive means to represent African landscape, subverting the traditional colonialist topos of exoticism and wilderness. While in his first “Australian” novel, Slow Man (2005), Coetzee problematized the notion of ethno-cultural identity in an age of globalization and mass migration by presenting multicultural individuals whose destabilized identities defy categorizations of belonging and not belonging, in Summertime he emphasizes the crucial role of native landscape in the construction of self-identity, reveals his strong bond with his native country and portrays the Karoo as an anchoring space in a world of heterogeneity. Although, as Coetzee earlier confessed, South Africa is “a wound within him”, in Summertime reflective nostalgia allows the writer to come to terms with his native country and his past.

The ferromagnetic lanthanum manganites show a negative entropy change peakΔ S under the application of a magnetic field at the Curie temperature. However, the magnetoelastic coupling effects lead to a first-order paramagnetic-ferromagn etic transition and an increasedΔ S compared to simple ferromagnets. This effect is analyzed in the framework of the Landau theory of phase transitions which shows a comparable influence of the magnetoelastic couplings and the ordinary magnetic ordering effect. The Pr$\text{}_{1-x}$Ca$\text{}_{x}$MnO $\text{}_{3}$ system shows a rich electric and magnetic phase diagram, with a ferromagnetic insulator phase for 0.15

Cell immobilization on encapsulation has been extensively investigated with the purpose of to providing immunoisolation but few attempts have been made to use this strategy for tissue regeneration. Our research efforts are currently focused on the functionalization of natural polymers, namely poly-saccharides, to promote their interaction with biological systems. Osteoprogenitor and stem cells were immobilized within alginate microspheres conjugated with oligopeptides including the Arg-Gly-Asp (RGD) sequence. Polymers were further modified to improve their biodegradability. After immobilization and under dynamic cell culture conditions, immobilized cells were viable, proliferated and differentiated. Immobilized cell further synthesized and extracellular matrix and expressed bone phenotypic markers, which indicates the capability of this approach to promote the regeneration of bone tissue. Current efforts are focused on promoting vascularization of bone tissue by using angiogenic factors as well as endothelial cells.

Opis:
In Japan, the treatment of waste concrete scraps has been one of the environmental issues. Therefore, new application using pulsed power discharge has been developed as the recycling method of the coarse aggregates from the waste concrete scraps. In the work, the dependences of the quality of the recycled coarse aggregate by the repetitive pulsed discharge treatments on the consumption energy were investigated. As the results, it was clear that the quality of the recycled coarse aggregate could be controlled by the number of discharge treatments. The recycled coarse aggregate, which satisfied class H under the regulations of Japan Industrial Standard (JIS A5005 and JIS A5021), was produced with the smallest consumption energy when the discharged energy from 0.02 μF of capacitor charged up to 400 kV applied to the waste concrete scraps during single discharge treatment.

The aim of this study was to acquire data on the physical properties and compression loading behaviour of seed of six corn hybrid varieties. The mean values of length, width, thickness, geometric diameter, surface area, porosity, single kernel mass, sphericity, bulk and true density, 1 000 kernelmass and coefficient of friction were studied at single level of corn seed moisture content. The calculated secant modulus of elasticity during compressive loading for dent corn was 0.995 times that of the semi-flint type; there were no significant differences in the value of this mechanical property between semi-flint and dent corn varieties. The linear model showed a decreasing tendency of secant modulus of elasticity for all hybrids as the moisture content of seeds increased.

Dissolution of milled (PDP) powder was studied in HCl, HNO3, and H2SO4 acidic solutions. The effects of dissolution acid, temperature, time, and PDP scrap powder to acid ratio on the leaching process were investigated and the most favorable conditions were found: (1) valuable metals (In, Ag, Mg) were recovered from PDP powder in a mixture of concentrated hydrochloric acid (HCl:H2O = 50:50); (2) the optimal dissolution temperature and time for the valuable metals were found to be 60°C and 30 min, respectively; (3) the ideal PDP scrap powder to acid solution ratio was found to be 1:10. The proposed method was applied to the recovery of magnesium, silver, and indium with satisfactory results.

Opis:
The genetic structure of Dactylorhiza incarnata var. incarnata populations is shaped not only by historical events such as recolonization after ice sheet retreat or limited seed and pollen dispersal, but also the bottleneck effect. During the last decade, D. incarnata var. incarnata has also experienced a strong decline in population numbers and sizes, due to habitat loss and fragmentation. In the present research genetic diversity was examined in eight populations located in northern Poland, using six nuclear microsatellites loci. At the species level our results showed a moderate mean level of genetic diversity (A = 4.67; Ae = 2.73; Rs = 4.48; Ho = 0.438; FIS = 0.224), which varied among the studied populations (A: 2.17–3.67; Ae: 1.55–2.69; Rs: 1.31–1.61; Ho: 0.292–0.631; FIS: −0.283–0.340). A considerable overabundance of homozygotes was detected in four populations (FIS within the range of 0.067–0.340), and in the remaining populations an excess of heterozygotes was observed. The average apparent out-crossing rate was also calculated (ta = 0.980), and primarily indicated a tendency to out-cross within the species. Moderate genetic differentiation was found among the studied populations (FST = 0.149; RST = 0.174; p < 0.05). The differentiation of the populations corresponded to relatively low gene flow value (Nm = 0.426) among populations, which amounted to only one migrant every second generation.

Field experiments with willow (Salix L.) coppice cultivation and Eko-Salix systems have been conducted at the University of Warmia and Mazury since 1992. In that wider context, the aim of the work described here was to compare energy inputs involved in setting up a plantation and producing biomass, and to assess the efficiency of willow-chips production under the coppice and Eko-Salix systems. The energy gain determined in the experiments was several to more than twenty times as great as the inputs needed to operate the plantation and to harvest willow biomass, this leaving both systems of willow cultivation under study attractive where setting up short-rotation coppices is concerned.

Opis:
Fast water flow facilitates ferrous ion transport leading to flow accelerated corrosion (FAC) of carbon steel and the possibility of a large accident through a failure of a secondary pipe in a nuclear power plant. Ion transport is directly linked to oxide properties such as the thickness, chemical composition and porosity. This work deals with a precise observation of the cross section of the corroded specimen focusing on an oxide passivity and its thickness using SEM (scanning electron microscope) and TEM (transmission electron microscope) as well as an apparent weight loss and a surface observation for the specimens corroded using a rotating cylindrical electrode autoclave system in pure water of pH 7 at 150°C having dissolved oxygen below 1 ppb within a flow rate range of 0 to 10 m/s. The Cr content in steel was changed from 0.02 to 2.4 wt%. Increasing the Cr content in the alloy, the FAC rate and oxide thickness decreased. The oxide porosity tends to decrease with the Cr content and immersion time owing to the development of Cr containing oxide. The oxidation behavior is not changed with the immersion time.

Resistance of material to airflow is an important factor to consider in the design of a dryer or an aeration system. The airflow resistance of soybean was determined with the modified airflow resistance apparatus. It was found that pressure drop increased with increase in airflow rate, bulk density, bed depth and decreased with moisture content. Modified Shedd equation, Hukill and Ives equation and modified Ergun equation were examined for pressure drop prediction. Airflow resistance was accurately described by modified Shedd equation followed by Hukill and Ives equation and modified Ergun equation. The developed statistical model comprised of airflow rate, moisture content and bulk density could fit pressure drop data reasonably well.

Opis:
Two high latitude fjords of Spitsbergen (Hornsund 77°N and Kongsfjorden 79°N) are regarded as being highly productive (70 g and 50 gC m−2 year−1) and having organic-rich sediments. Hornsund has more organic matter in its sediments (8%), nearly half of it of terrestrial origin, while most of that in Kongsfjorden (5%) comes from fresh, marine sources (microplankton). Analysis of the carbon sources in both fjords shows that a major difference is the much larger seabird population in Hornsund-dominated with over 100 thousands pairs of plankton feeding little auks in Hornsund versus 2 thousand pairs in Kongsfjorden, and marine food consumption estimated as 5573 tonnes of carbon in Hornsund, versus 3047 tonnes in Kongsfjorden during one month of chick feeding period. Seabird colonies supply rich ornithogenic tundra (595 tonnes of C, as against only 266 tonnes of C in the Kongsfjorden tundra). No much of the terrestrial carbon, flushed out or wind-blown to the fjord, is consumed on the seabed – a state of affairs that is reflected by the low metabolic activity of bacteria and benthos and the lower benthic biomass in Hornsund than in Kongsfjorden.

Opis:
Demand for Ganoderma lucidum basidiocarps on the global market is increased due to its numerous health benefits. As they are rare in nature and traditional cultivation on logs is not ecologically and economically justified method, current trend is finding of good alternative substrate for production. Whether wheat straw, the most abundant crop residue in Europe, could be a novel substrate for G. lucidum cultivation was the question which led to the definition of the goals. Two wild and one commercial strains were objects of the study. Despite some morphological differences among basidiocarps, all strains belong to G. lucidum sensu stricto, which was confirmed by analyses of ITS, tef1-a and rpb2 gene sequences. Wheat straw showed as a good substrate, namely the periods required for the complete colonisation of wheat straw by mycelium as well as the formation of primordia and basidiocarps were relatively short. The totally fresh and dry yield and biological efficiency were also significant. If it is taken into consideration that untreated wheat straw was used, validities of its introduction in industrial-scale G. lucidum cultivation can be demonstrated.

Wzrastająca liczba przypadków alergii na mleko krowie wśród niemowląt wywołała zainteresowanie mlekiem koniowatych (klaczy koni i osłów) z powodu podobieństwa składu tego mleka do mleka kobiecego. W badaniach klinicznych wykazano bardzo dobre tolerowanie tego rodzaju mleka przez organizm niemowląt i małych dzieci. Mleko ośle uważane jest za użyteczne w zapobieganiu arteriosklerozie i w regulowaniu reakcji immunologicznych ludzi w starszym wieku. Mimo podobieństwa do mleka kobylego wyróżnia się ono szczególnie dużą zawartością lizozymu, dzięki któremu charakteryzuje się właściwościami antybakteryjnymi nawet po pasteryzacji, co między innymi sprawia, że jest szczególne przydatne do produkcji napojów probiotycznych.
An increasing number of cases of cow’s milk allergy in infants evoked interest in equine milk (milk from female horses and donkeys) owing to its composition similar to that of human milk. Clinical studies proved a very good tolerance of this kind of milk by the body of infants and young children. Milk is considered useful in preventing atherosclerosis and in controlling immune responses in elderly people. Although similar to mare's milk, donkey’s milk has one distinctive characteristic: it contains a particularly high content of lysozyme. For that reason, it is characterized by antibacterial properties even after pasteurization and, therefore, among other things, it is particularly useable in the production of probiotic beverages.

Opis:
A study concerns the balance of mass and energy in the process of gasification of willow chips (acquired in 5-year rotation), as well as in the process of combustion of the gasification product with flue gas heat recovery. Thermochemical conversion of willow biomass resulted in the production of raw gas with the calorific value of 4937 kJ/kg. The product of gasification comprised a mixture of gaseous compounds, tars and water vapour. The gaseous compounds determined in the study included: hydrogen (8.30%), carbon monoxide (27.51%), methane (1.51%), carbon dioxide (3.79%), nitrogen (55.87%) and small amounts of hydrocarbons C1-C3. The ultimate production output of willow fuel was equal to 91.5 kg of chips per hour and the power output achieved 315 kW. Raw gas produced from willow biomass, mixed with air, was burnt at a temperature exceeding 1000oC and the flue gas heat was recovered in a water boiler and distributed in the central heating system. The collected thermal energy accounted for over 79% of the chemical energy of the biomass at the start of the process.

[N-salicylidene glycinato diaqua cobalt (II) dimer] (SGCo)2, [N- salicylideneglycinato-di-aqua-nickel(ll)dimer] (SGN)2, [N-salicylideneglycinato-aqua-copper(II)] (SGC) and [N-salicylidene glycinato diaqua zinc(II) dimer] (SGZ)2 have been synthesized and characterized through a rapid, simple, and efficient methodology in excellent yield. These compounds were screened for in vitro antibacterial activities against six pathogenic bacteria, such as Shigella sonnei, Escherichia coli, Bacilus subtilis, Sarcina lutea, Staphylococcus aureus and Pseudomonas arioginosa. The antibacterial activity was determined by the disc diffusion method using DMSO as solvent. The results indicate that (SGC) compound exhibit a significant antibacterial activity, depending on the bacterial strain and (SGCo)2, (SGN)2 and (SGZ)2 compounds show a moderate sensitivity even with higher doses. All these compounds were found to possess cytotoxic effect.

Opis:
The present state of research reveals that basically Fr. J.M. Bochenski (1902-1995) left three versions of the formalizations of St. Thomas Aquinas’ fifth way. The first version comes from the article Die fünf Wege, published in 1989, and the third one, which is unauthorized, from the book Gottes Dasein und Wesen. Logische Studien zur Summa Theologiae I, qq. 2-11, published in Munich in 2003. These works are completed by the second version from two manuscripts of the book: one German (1989) and one Polish (1993). The above mentioned texts have shown the contribution made by Fr. J.M. Bochenski into the realization of the intended application of the tools of contemporary logic in the field of philosophy of God as well as theology. One of the main followers of these ideas in Austria has been Paul Weingartner (born 1931). In 2010 he published God’s Existence? A Logical Commentary on the Five Ways of Thomas Aquinas, a book which makes direct references to J.M. Bochenski’s works, and like Bochenski’s work it is a logical commentary to certain fragments of St. Thomas Aquinas’ Summa Theologiae.
Obecny stan badań wskazuje, że formalizacje piątej drogi św. Tomasza z Akwinu pozostawił o. J. M. Bocheński (1902-1995) zasadniczo w trzech wersjach. Pierwsza z nich pochodzi z artykułu zatytułowanego Die fünf Wege z 1989 r., trzecia (nieautoryzowana) z książki Gottes Dasein und Wesen. Logische Studien zur Summa Theolgiae I, qq. 2-11 wydanej w Monachium w 2003 r. Uzupełnieniem tych opracowań stanowi wersja druga, pochodząca z manuskryptów książki: jeden w języku niemieckim (1989 r.), drugi w polskim (1993 r.). Publikacje te ukazują wkład jaki poczynił o. J. M. Bocheński w realizację zamierzenia stosowania narzędzi współczesnej logiki na terenie filozofii Boga i teologii. Jednym z głównych, współczesnych kontynuatorów tych idei w Austrii jest Paul Weingartner (ur. 1931 r.). W roku 2010 opublikował on książkę: God’s Existence? A Logical Commentary on the Five Ways of Thomas Aquinas, która w wielu miejscach nawiązuje wprost do prac J. M. Bocheńskiego i tak jak praca tego ostatniego jest komentarzem logicznym do pewnych fragmentów Sumy Teologicznej św. Tomasza z Akwinu.

Opis:
Lymphocytic infiltrations located in the extracellular matrix often accompany canine skin cancer. They can be characterised as an inflammatory infiltration and/or a second tumour – lymphoma. The aim of this study was an immunohistochemical analysis of a lymphocytic infiltration which accompanies spontaneous skin cancer. Twenty basal cell carcinoma, 20 non-keratinizing squamous cell carcinoma, 20 keratinizing squamous cell carcinoma and 8 sebaceous gland carcinoma samples which were accompanied by a lymphocytic infiltration and/or secondary lymphatic follicles were verified histopathologically. The expression of bcl-2, CD3, CD79α, Ki-67, MCM-3 and MCM-7 in the lymphocytic infiltration was evaluated. Four types of lymphocytic infiltrations were found: I – diffuse bcl-2⁺, II – diffuse bcl-2⁻, III – follicular bcl-2⁺/⁻ where the centre was bcl-2⁻, and the marginal zone of the follicles and the extrafollicular area were bcl-2⁺ and IV – aggregated bcl-2⁺, where the centre and periphery were bcl-2⁺. The I and IV type corresponds to lymphoma, II type is non-neoplastic immune response and III type suggest reactive follicular hyperplasia. The proliferation of lymphocytes which demonstrated the expression of neoplastic markers (I and IV), suggests preneoplastic phase (pseudolymphoma) or lymphoma – the second independent tumour. A high proliferative index of the follicular blc-2⁺/⁻ follicular infiltration indicates an increased immunological response of the host against skin cancer.

Opis:
General behavior of In/GaAs couple heat-treated at 570°C for 2 hours was studied with secondary-ion-mass spectrometry, scanning electron microscopy, Rutherford backscattering spectroscopy and Nomarski microscopy. It is shown that, besides the well-known InGaAs crystallites which epitaxially grow upon dissolution of the substrate, In interacts with the substrate dislocations to form In(Ga)As dendrites. The driving force for this process is presumably excess arsenic reported to be present in the vicinity of the individual dislocations.

Opis:
The large effluxes generated by high-tech plasmas force plasmas to non-equilibrium conditions. This implies that plasma features are decoupled from each other and that therefore different methods have to be used quasi-simultaneously to characterize the plasma. Even more insight in plasmas and methods is obtained if polydiagnostics is applied to a series of plasma conditions that gradually differ in equilibrium departure. After discussing methods of passive and active spectroscopy, we apply polydiagnostics on an argon plasma operated in open air. By introducing H2 and reducing the power we approach conditions of cool atmospheric plasmas (CAPs). It is seen that especially the passive methods for the electron temperature determination are very sensitive to the degree of equilibrium departure suggesting that active spectroscopy is preferable. However, one should realize that lasers can easily heat cool plasmas. This is due to the fact that the ionization degree of (semi-) CAPs is small.

Opis:
The reaction kinetics for the preparation of ammonium dinitramide (ADN) is described. ADN is the ammonium salt of the dinitramide anion, and belongs to the group of inorganic oxidizers, mainly useful for energetic rocket propellant formulations, particularly for underwater applications. It is also a potential candidate to replace ammonium perchlorate (AP), in order to develop chlorine-free, green propellants. At HEMRL, ADN is prepared by the nitration of ammonium sulfamate (AS) using mixed acid, followed by hydrolysis, neutralization with ammonia (g) and rectification using solvent. The nitration of ammonium sulfamate (AS) is carried out at a subzero temperature of -40 ±1 °C. The yield of ADN is reliant on the formation of dinitramidic acid, an intermediate product formed during the hydrolysis step, and its stability is predominantly dependent upon the level of acidity and temperature of the reaction medium. Prior to these kinetics studies, process optimization of the nitration of ammonium sulfamate (AS) was performed and gave the final mole ratio of AS:HNO3:H2SO4. Since the nitration of AS is sensitive to temperature, the rate of reaction was studied at fixed temperatures with variation of time, keeping all of the other parameters, such as vessel volume, agitator speed, feed rate etc., constant. During these studies, predetermined quantities of ammonium sulfamate (AS) and mixed acid were allowed to react at a fixed temperature (-40 ±1 °C) for different reaction periods to generate the concentration profile of AS. Using this concentration profile, the reaction order and reaction rate constant were evaluated. In order to find the effect of temperature on the reaction rate and yield, experiments were conducted at other temperatures such as -30 and -50 °C. In the present studies, it was found that the optimum temperature of nitration is -40 ±1 °C and that the rate of reaction follows a pseudo second order process with rate constant 0.01113 (min-1)•(mol/L)-1. The reaction time evaluated for 55 to 60% conversion is about 70-80 minutes at -40 ±1 °C, based on this kinetics. The activation energy of AS nitration was found to be -4.6 kcal/mol, using the reaction kinetic data based on the temperature dependent rate equation derived from Arrhenius’s law.
