    Opis:
    Five complex soil profiles in gully system on Nałeczów Plateau (E Poland) were examined. They represent the loess sediments modified by soil processes and postpedogenic transformations. Two examined profiles represent natural and mature Luvisols with diagnostic illuvial horizon (Bt argillic) developed on the edge of plateau geomorphologic level and in the relict valley bottom. The other soil profiles reflects postpedogenic soil degradation, redeposition and secondary accumulation (deluvia, colluvia and/or proluvia). Record of these processes are the micromorphological features created by lithological processes (=primary loess and secondary pedoliths) or by pedogenesis (mainly bioturbation, illuviation, de- and recalcification). The important group of microfeatures are pedorelicts which clearly confirm genetic dependences of pedoliths (deluvia and proluvia) and soils developed in situ and located in higher hypsometric levels in the catchment.

    Opis:
    The investigation was conducted in the eastern part of the Nałęczów Plateau, a region of the Lublin Upland, in eastern Poland. The loess cover of this region was formed mainly during the last glaciation, and loess accumulation lasted until 15,000–12,000 BP. The undulating loess plateau with numerous oval-shaped closed depressions (CDs) is the main landform in the study area. Particle size distribution and SEM analyses were conducted for loess profiles under the bottoms and on the slopes of 4 CDs. Grain-size distribution characteristics as well as qualitative and quantitative micromorphological characteristics of the the loess forming the bottoms and slopes of the depressions were compared and discussed. It was documented that the differences between the loess forming the bottoms and slopes of the depressions are insignificant in the case of clay fraction content, but are considerable in the case of microstructure characteristics. The differences documented result from the impact of syn- and post-depositional diagenetic processes related mainly to suffosion and hydroconsolidation occurring under the influence of water. A quantitative assessment of the morphological effects of these processes was carried out in the context of the origin of closed depressions. The morphological effect of Holocene diagenetic processes was manifested in the deepening of the initial closed depressions formed previously under the influence of primary morphogenetic processes.

    Opis:
    Introduction. Schizophrenic patients present cognitive dysfunctions which are regarded to be one of endophenotypical markers predisposing to schizophrenia. Currently, schizophrenia can be treated as a neurodegenerative and neurodeveloping disease with genetic background. Objective. Assessment of the possible positive effect of neuropsychological rehabilitation in schizophrenia, in patients presenting cognitive dysfunctions. An additional aim was to verify the hypothesis that some genetic polymorphisms can be a prognostic factor for success in neuropsychological rehabilitation. Material and methods. 41 participants and 40 control subjects were randomly selected. Both groups had the diagnosis of paranoid schizophrenia. Cognitive functions were checked with the Wisconsin Card Sorting Test, Trail Making Test, and Stroop Test at the beginning and end of the experiment. In the research group, each patient trained with the rehabilitation programme RehaCom, whereas the control group did not receive such training. Genes COMT rs4680 and BDNF rs6265 were analysed in the genetic part of study. Results. RehaCom procedures appear to be useful in the neuropsychological rehabilitation of cognitive dysfunctions in patients diagnosed with schizophrenia. The research group showed a moderate improvement in the training programmes. Analysis of parameters obtained in the neuropsychological tests showed a slight improvement in both groups. At the present time, analysis of the polymorphisms of genes cannot be treated as a prognostic factor for the success of neuropsychological rehabilitation because statistical analyses showed few dependences with little statistical significance. Conclusions. Cognitive rehabilitation produces moderate improvement in cognitive functioning.

    Opis:
    The Volochysk site belongs to important and unique loess sites in the Podolia Upland (W Ukraine) because it contains relatively well-developed loess deposits representing the last and penultimate glacial cycles. This loess-palaeosol sequence consists of pedocomplex S1 (MIS 5) developed on loess L2, and loess L1 (MIS 4-2) with the palaeosols of lower, interstadial rank. In this sequence, different periglacial structures were found, including the largest ones of ice-wedge cast type. Different quartz and polymineral fractions separated from the samples collected in the Volochysk site were dated using luminescence methods (SAR OSL, post-IR IRSL and TL) in three Polish luminescence laboratories in Gdańsk, Gliwice and Lublin. In total, 69 luminescence dating results were obtained for 18 samples. The methodological and research aims were to carry out mutual verification of the obtained dating results as well as to analyse and interpret the differences between them, and to determine the age of distinguished deposit layers and the period of cryogenic activities. The luminescence dates of the sediments, which were deposited during MIS 2, 3 and 4, corresponded fairly well to the ages attributed to these stages. They also indicate the age of periglacial phenomena. However, the TL dates were generally older than the OSL ones, especially those obtained for the sediments deposited during MIS 5 and 6. The results of the research of the Volochysk sequence were compared with those obtained in past years for the loess deposits of the Volhynian Upland (north of Podolia) during similar inter-laboratory analyses conducted to determine their age. The results of OSL datings of the older deposits (MIS 5 and MIS 6) are underestimated irrespective of the used method, and the type (quartz, polymineral) and size of grains. Numerous attempts were made to explain this phenomenon, which, however, give no answer. It was only found that this underestimation corresponded to the equivalent dose value of ~150 Gy.

    Opis:
    The experiment was conducted with 60 slow-growing Hubbard JA 957 broilers and with 60 Silkies chickens reared until the 63rd day of life, in three replications, 20 birds each, in a closed building on litter. A three-stage feeding program was applied in the rearing period. Feed mixtures used in the experiment did not differ in contents of nutrients. In the first stage of rearing (till 21 days of life) the chickens were fed a standard starter feed mixture containing: 20.98% of total protein, 2,845 kcal/kg of me-tabolizable energy, 1.17% of lysine and 0.98% of met. + cys. In the period from 22 to 56 days of life they were receiving a grower type mixture containing: 20.0% of total protein, 2,900 kcal/kg of energy, 1.04% of lysine and 0.88% of met. + + cys., whereas contents of these components in the finisher type mixture administered till the end of the rearing period were as follows: 18% of protein, 2,965 kcal/kg of EM, 0.90% of lysine and 0.78% of met. + cys. On day 63 of rearing, 12 cockerels and 12 hens were selected random from each group. The birds were slaughtered in a poultry slaughter house, and specimens of their major breast muscle (m. pectoralis superficialis) and thigh muscle (biceps femoris) were sampled for analyses. The breast and leg muscles of the birds were characterized by diversified diameters of muscle fibers depending on bird genotype. The greatest diameters were found in breast and leg muscles of the slow-growing Hubbard JA 957 broilers, which was confirmed statistically (P < 0.01). It was also demonstrated that the mean diameter of muscle fibers of Silkies chickens was more than two times smaller compared to the Hubbard JA 957 chickens.
    Profil histologiczny mięśni piersiowych i nóg kurcząt Jedwabistych oraz wolno rosnących Hubbard JA 957. Badanie przeprowa- dzono na 60 brojlerach wolno rosnących Hubbard JA 957 oraz 60 kurczętach Jedwabistych odchowywanych do 63. dnia życia, w trzech powtórzeniach po 20 szt., w zamkniętym budynku na ściółce. W okresie odchowu zastosowano trzyfazowy program żywienia. Mieszanki użyte w doświadczeniu nie różniły się pod względem zawartości składników pokarmowych. Kurczęta w pierwszym okresie odchowu do 21. dnia życia żywiono standardową mieszanką typu starter: 0 zawartości 20,98% białka ogólnego, 2845 kcal na kg energii metabolicznej, 1,17% lizyny i 0,98% met. + cys. W okresie od 22. do 56. dnia stosowano mieszankę typu grower, zawierającą 20,0% białka ogólnego, 2900 kcal na kg energii metabolicznej (EM), 1,04% lizyny i 0,88% met. + cys. Zawartość wcześniej wymienionych składników w mieszance fmiszer, stosowanej do końca odchowu, wynosiła odpowiednio: 18% białka, 2965 kcal na kg EM, 0,90% lizyny i 0,78% met. + cys. W 63. dniu odchowu wybrano z każdej grupy po 12 kogutów i 12 kur o masie ciała zbliżonej do średniej w grupie. Kurczęta ubito w ubojni drobiu i pobrano wycinki mięśnia piersiowego powierzchniowego (m. pectoralis supetficialis) oraz dwugłowego uda (biceps femoris). Mięśnie piersiowe i nóg ptaków doświadczalnych charakteryzowała zróżnicowana średnica włókien mięśniowych w zależności od genotypu. Największą średnicą charakteryzowały się mięśnie piersiowe 1 nóg ptaków wolno rosnących Hubbard JA 957, co zostało potwierdzone statystycznie (P < 0,01). Stwierdzono, że średnica włókien mięśniowych kurcząt Jedwabistych była o ponad połowę mniejsza w porównaniu do kurcząt Hubbard JA 957.
