Opis:
Inonotus rickii (Pat.) Reid is a pathogenic wood-decaying fungus that causes severe decay in several ornamental urban trees in Europe. It has been known to occur on different hosts in Sicily (Italy) since 1985, and in Rome (Italy) since 2003. Some physical and mechanical wood features were studied according to the standards in order to propose an investigation methodology to set a deterioration ranking of urban trees. In this phase of the study, Celtis australis L., Acer negundo L., Acer campestre L., Robinia pseudoacacia L., Tilia × vulgaris Hayne, Ulmus minor Mill., Platanus × acerifolia (Aiton) Willd. and Quercus ilex L. were studied. The data were analyzed using ANOVA and M-ANOVA tests to check the differences among the specimens. A risk matrix was created in order to combine the features that showed statistical differences between the control specimens and the inoculated specimens, in order to establish, in vitro, a degradation ranking among the wood species. The wood species which showed no in vitro durability to I. rickii, were the same ones that displayed susceptibility in the living trees.

Opis:
The aim of the study was to determine the trophic state of the Vistula Lagoon in 2007–2009. The analysis of various trophic state indices, abiotic parameters and different water classifications indicated the eutrophy and even advanced hypereutrophy of the lagoon waters. The composition, abundance and biomass of phytoplankton likewise reflect the eutrophic nature of this water body. For this lagoon, Reynold’s functional groups of phytoplankton were used as an indicator of eutrophication for the first time. The dominant phytoplankton organisms in the surface waters belong to 8 functional groups: S1, X1, F, J, K, H1, LO, M. Some key concepts of the EU Water Framework Directive were implemented in this study.

Opis:
The paper presents the results of a qualitative research on a topic of the film imagery of people with physical disabilities. Selected feature films were analysed on the basis of specific questions regarding femininity, masculinity and sexuality of persons with physical disabilities. Additionally, the research was also based on three imagery stages: the early-exploitation, the super-cripple and normality. The main result of the analysis is to settle two discourses: the main and the alternative. Despite the social changes, most popular representations are stereotypical, presenting disability as a total category and are shown from the masculine perspective. The most important presentation within the alternative discourse must include disability as a transparent, unseen difference.

Opis:
In the paper, an attempt towards morphological analysis implementation into grain physical features extraction, with the use of APR software, has been presented. The main objective of the research is to determine the physical characteristics of wheat grains in order to assess the automatic grain quality review. Photographic macro images of wheat grains were taken for the purpose of this study, and then they were processed using the APR application. Properly prepared graphic material has been subjected to segmentation and morphological analysis. Parameters derived from morphological analysis are presented synthetically and form the basis for further research focused on statistical analysis.

Głównym celem badań jest określenie cech fizycznych ziarniaków pszenicy pozwalających na ocenę jakościową ziarna w procedurze automatycznej. W ramach badań wykonano zdjęcia fotograficzne makro ziarniaków pszenicy, które następnie poddano przetwarzaniu przy użyciu aplikacji APR. Odpowiednio przygotowany materiał graficzny poddany został segmentacji i analizie morfologicznej. Parametry uzyskane z analizy morfologicznej zostały przedstawione w ujęciu syntetycznym i stanowią podstawę dalszych badań na gruncie analizy statystycznej.

Opis:
Biometrical features of plants and physical properties of amaranth seeds (Amaranihus cruentus) of a population variety originating from South America and a new Polish variety Rawa have been studied. New research methods were worked out or old methods were adapted to suit specific features of this plant. Studies were carried out in the period 1995-96 (population variety) and in 1997 (variety Rawa). Alongside field experiments plot experiments with varying sowing density were conducted in order to evaluate the influence of the number of plants per 1 mL plant on the variability of biometrical features and yields. Plant and wisp height, stalk thickness, wisp mass, number of plants per 1 mL and biological yield as well as seed self-shedding were determined. Geometrical properties (thickness, width, and length) were determined for individual seeds together with their aerodynamic features, surface roughness, resistance to static loading and microstructure. Whereas seed mass was characterised by such parameters as: density, porosity, outer and inner friction, angle of repose and chute, rehological properties and qualitative features. It has been found out that Rawa variety was more uniform than population variety and gave yields that were 50% higher. Seed sowing density differentiated plant biometrical features. Seed self-shedding in different weather conditions ranged from 0,3 to 2.1% of the biological yield. Physical properties of seeds changed according to moisture levels which was described by the regression lines and curves. It was found that with moisture decrease seed thickness, and the mean values ranged from 0,58 to 0,93 mm. Seeds of Rawa variety were developed better. The weight of 1000 seeds was from 0,60 g (very dry seeds) to 0,95 g (very moist seeds). Density was increasing with the decrease in moisture from 653,3 to 842,0 kg/m3. Whereas, porosity of the seed mass decreased from 53,5 to 40,0 %. Both the angle of repose and chute were decreasing with the decrease in the coefficient of inner and outer friction while the roughness of the seed surface was increasing. Amaranth seeds appeared to be more resistant to mechanical loading. The force ranging from 10.7N (very moist seeds) to 70,6N (dry seeds) was sufficient to damage the structure of an individual seed. Aerodynamic seed features depended on such parameters as seed load bearing surface, width, length and weight. With the increase in these parameters critical velocity increased linearly, and the coefficient of volatility decreased according to the same formula.A generalised Maxwell model with three branches was used to describe the phenomena of stress relaxation in the seed mass. It led to the conclusion that amaranth seeds en mass show strong viscoelastic properties. Seed qualitative features show high nutritive value, and evaluation of their microstructure showed that they contain unique starch with kernels thet are very uniform in size (1-1,5(m). Learning about biometrical plant features and their physical properties allowed for working out agrophysical basic for the harvest technology of this plant.
