Opis:
Core drilling of a hole Bysławek-2 consisted of gyttja and peat, lying on the mineral deposits (fluvioglacial sand). Lake sediments and peat were investigated by pollen analysis and radiocarbon dating (AMS). Sedimentation of mineral deposits took place into the subglacial channel, during the Main Stage of the Vistula Glaciation. The beginning of sedimentation in lake is dating at 13 340 š 70 years 14C BP, but pollen data suggest the Alleröd character of vegetation. According to pollen analysis gyttja and peat covered the period from the Alleröd to the Subboreal. The Alleröd forest dominated by Pinus sylvestris became more open in the Younger Dryas. The Holocene history of vegetation is characterized by relatively low content of Carpinus and Fagus in forest. Human impact was also generally low throughout the Holocene.

Opis:
We report on an analytical study of the statistics of conductance, g, and shot-noise power, p, for a chaotic cavity with arbitrary numbers N$\text{}_{1,2}$ of channels in two leads and symmetry parameterβ = 1, 2, 4. With the theory of Selberg's integral the first four cumulants of g and first two cumulants of p are calculated explicitly. We give analytical expressions for the conductance and shot-noise distributions and determine their exact asymptotics near the edges up to linear order in distances from the edges. For 0 < g < 1 a power law for the conductance distribution is exact. All results are also consistent with numerical simulations.

Opis:
Badania związane z tematem pracy prowadzono w warunkach doświadczenia polowego założonego w sąsiedztwie składowiska komunalnego w Tarnowie. Próbki nasion pszenicy i bobiku oraz bulw ziemniaka do badań pobierano w okresie zbioru plonów (w latach 2006 i 2007), z poletek doświadczalnych położonych z każdej strony od badanego obiektu, w dwóch strefach 50-200 i 250-500 metrów od jego granic. Jak wynika z uzyskanych danych, występowanie najwyższej średniej liczebności grzybów mikroskopowych - Micromycetes odnotowano na powierzchni bulw ziemniaków 382 jtk/g–1 suchej masy (min 10 - max 1100 jtk/g–1), a najniższej na nasionach pszenicy 201 jtk/g–1 (min 10 - max 900 jtk/g–1). Wśród wyizolowanych grzybów pleśniowych stwierdzono szczepy potencjalnie toksynotwórcze np.: Alternaria alternata, Aspergillus flavus, Fusarium graminearum, Penicillium rugulosum czy Trichoderma viride. Najsilniejszym działaniem fitotoksycznym odznaczały się szczepy: Alternaria alternata, Penicillium rubum i Penicillium lanosum (wyizolowane z bulw ziemniaków), a najsłabszym działaniem szczepy Alternaria alternata i Fusarium oxysporum (wyizolowane z nasion pszenicy). Choroby grzybowe atakujące nasiona i bulwy występowały w największym nasileniu na roślinach uprawianych na terenie zrekultywowanego sektora oraz w bezpośrednim sąsiedztwie czynnego sektora składowiska.
The investigation was carried out as a field experiment in the vicinity of municipal landfill site in Tarnow. Samples of spring wheat seeds and potato tubers were taken at the harvest time (in 2006 and 2007), from plots located on each side of landfill site in two zones: up to 250 m and 250-500 m from its boundaries. Considering the results of the research on the occurrence of Micromycetes it was found that the highest number of these microorganisms was on the surface of potato tubers - 382 cfu•g–1 d. m. (min 10 - max 1100 cfu•g–1), and the lowest on spring wheat seeds 201 cfu•g–1 (min 10 - max 900 cfu•g–1). Among isolated molds were potentially toxin forming strains eg Alternaria alternata, Aspergillus flavus, Fusarium graminearum, Penicillium rugulosum and Trichoderma viride. The most toxic were strains of Alternaria alternata, Penicillium rubum and Penicillium lanosum - isolated from potato tubers, and the least toxic were strains of Alternaria alternata and Fusarium oxysporum - isolated from spring wheat seeds. Fungal diseases of seeds and tubers predominated on plants cultivated on plots located in the area of reclaimed sector and in the vicinity of active sector of landfill site.

Opis:
This paper presents the results of testing samples of shield-centering elements from medium-voltage surge arresters. The elements were made of TSE glass textolite. The elements have been dismantled from different operated surge arresters, which were subjected to discharge currents (short-circuit currents) of different intensity and duration. The discharge currents led to degradation of the tested elements with various degrees of advancement. The degradation was investigated using microscopic methods and energy-dispersive X-ray spectroscopy (EDS). Changes in the content of elements of the surface of textolite materials - as the degradation progresses - were documented. It was found that high discharge current flows resulted in melting of the organic binder, epoxy resin, especially its surface layer. Partial charring and even burning of the resin was noticeable. Furthermore, it was found that with increasing degradation on the surface of the TSE laminate, the carbon and oxygen content, which are part of the organic resin, decreases. Simultaneously the amount of silicon, calcium and aluminium, which are present in the glass fibres, increases. The charring effect of the resin and the formation of conductive paths result in a decrease in the performance of surge arresters and their subsequent failure.

Opis:
Plant communities which form orchard edges are a vital element of ecological infrastructure enriching these agrocenoses. The research was conducted in an orchard environment made up of apple orchards and their edges in the form of agricultural cultivations, tree clumps and a road lined with trees and shrubberies. The study aim was to determine the impact of the orchard edge plant diversity onto the number and abundance of Ichneumonidae subfamilies in the orchards. The study showed that orchard environments made up of an apple orchard and edge plants of various species create better living conditions for Ichneumonidae parasitoids than the environment of an orchard and neighbouring agricultural cultivations. The diversity of orchard edge plants positively influences the abundance of the Ichneumonidae subfamilies rather than the number of subfamilies in the orchard. In the orchard habitat the following dominant subfamilies were found: Campopleginae, Cryptinae, Orthocentrinae and Pimplinae. These entomophages may control the abundance of pests infesting orchards.

Opis:
Scientists around the world are interested in edible insects as a source of valuable nutrients. Among the most often described are crickets, which represent a source of significant amounts of protein, lipids, vitamins, and minerals. This article reports results of a study into the effect of starch-to-cricket powder (CP) addition on the free amino acid profile as well as potential odorants in gluten-free (GF) bread. A significant 2.6-fold increase was observed in the content of essential amino acids in the CP-enriched GF bread. Moreover, the CP addition resulted in the formation of many volatile compounds, such as pyrazines, furans, and sulfur-containing compounds, which exhibit strong aroma-enhancing properties. The attractiveness of the CP-enriched bread was confirmed by the results of the sensory analysis, showing a significant improvement in its flavor when compared to the traditional GF bread without CP. GF bread enriched with CP was characterized by caramel, roasty, and cooked potatoes notes. On the basis of the obtained results, it was concluded that the use of CP not only improves the nutritional value but also aroma of GF bread.

Opis:
In a pot experiment the impact of composts containing polymeric materials modified with biocomponents on the diversity of crops of oats and mustard was examined. The composts used in the study were produced in the laboratory from wheat and rape straw, and pea seed cleaning waste with 8-percent addition of chopped biopolymer materials (films) which were prepared in the Central Mining Institute (GIG) in Katowice. Three polymers differing in content of starch and density were selected for the composting. The pot experiment was conducted on three substrates: light and medium soil and on the sediment obtained after flotation of zinc and lead ores, coming from the landfill ZGH “Boleslaw” S.A. in Bukowno. The need for using such materials and substrates results from the conditions of processing some morphological fractions of municipal waste and from improving methods of reclamation. Yield enhancing effect of composts depends on the substrate on which the compost was used, cultivated plants and crop succession. Application of composts prepared with 8% of polymeric materials based on polyethylene, modified with starch as biocomponent, resulted in significantly lower yields in sandy (light) soil in case of oats and, in some cases, in medium soil. Subsequent plant yield did not differ significantly between the objects fertilized with compost.

Opis:
The positron annihilation lifetime spectroscopy was applied to the samples of the human uterine leiomyomas and the normal myometrium tissues taken from the selected place of the uterus during a surgery. The method indicated differences in values of the measured positron annihilation lifetime spectroscopy parameters (lifetimes and intensities) between healthy and diseased tissue samples. The additional measurements were performed either in darkness or in presence of visible light which influenced the free radicals present in both kind of tissues and, as a result, made changes in free annihilation and o-Ps decay lifetime and intensity values.
