    Opis:
    This paper is a review of the studies attempting, among others, to provide answer to the question if the variation in surface water chemistry in a small afforested mountain catchment depends on site characteristics from which soil samples are collected. The characteristics considered in the paper included: setting such as elevation a.s.l., slope, soil, and surrounding stand – age, species composition, etc. The assumed variation was ascertained and described in the framework of distinguished five areas termed micro−catchments (or partial catchments). This paper also contains a brief description of the research method, results and conclusions which could be formulated as a result of the discussion and indepth analysis of obtained results.

    Opis:
    Since 1997, the experimental Potok Dupniański catchment in the Beskid Śląski Mountains (Wisła Forest District) has been an area subjected to intensive hydrological and hydrogeochemical research aimed at improving knowledge about the ecological growth conditions of one of the most valuable Norway spruce (Picea abies (L.) Karsten) ecotype – the Istebna spruce. Environmental conditions and comparison with the stands growing in similar environments in the 18th and 19th century in the Beskid Żywiecki region, as well as historical sources have shown that Istebna spruce is not a native provenance. Thus, the analysis of the state of forest management in the past times appears an important contribution to the above−mentioned earlier research. An increase in forest resources mainly resulting from the higher share of stands in older age classes and a decline in species diversity is a characteristic feature of the studied area. It is believed that the growing share of fir and beech in forest plantations as a consequence of underplanting would improve this situation.

    Opis:
    Research on the effect of birch regeneration on changes occurring in the environment on former farmlands included a quantitative and qualitative analysis of the biomass growing on the research plots. Five experimental plots were selected in the Mazovia region: two in Dobieszyn and the Kampinos National Park and one in Kozienice. The analysis performed on each plot was concerned with the amount and chemical composition of biomass in four patches of vegetation, characterised by the different ages of the birch trees growing there. The vegetation patches were classified according to age group, i.e. I: 1–4 years old, II: 5–8 years old, III: 9–12 years old and IV: over 12 years old. Biomass samples were collected in the field and determined in kg DM/ha using the following components: roots, stem, bark,branches, assimilation apparatus, litterfall and the total biomass of the other (except birch) plants. For all the above-mentioned groups, the content of the elements N, C, S, Ca, K, Mg, Na, P, Mn, Cu, Fe, Zn, Pb, and Cd was determined. This allowed us to obtain both the values of the concentrations of particular substancesand their allocation in both the organic matter and litterfall. The aim of theresearch was to discover whether the allocation of elements changes with the age of birch growing on former farmland.

    Opis:
    The aim of the study was to apply the forest soil trophic index (ITGL) in the assessment of post−agricultural soil under naturally regenerated silver birch (Betula pendula Roth.) stands. The study was conducted in Mazowieckie region (central Poland) in 10 locations (tab. 1). In each location we established 4 study plots with naturally regenerated silver birch of different age. The age of the investigated stands ranged from 2 to 17 years. On each study plot samples from three upper soil horizons (0−5 cm, 5−15 cm and 15−50 cm) were collected for laboratory analysis. The following characteristics were determined in the soil samples: pH, organic carbon (C) and total nitrogen (N) content, particle size and the content of exchangeable base cations (Ca, Mg, Na and K). These soil characteristics were on used for ITGL calculation. Chemical properties of soils under silver birch regeneration varied with regard to trees age, whereas physical attributes turned to be rather stabile over the time (tab. 2). According to ITGL value investigated soils were classified as eutrophic. It is probably the effect of high base cations content, which is a result of systematic fertilization during the long term agricultural use. The insignificantly different ITGL values for the studied soils (tab. 3) indicated their similarity in terms of site productivity potential and soil−geological characteristics. The soil properties, especially the quality of soil organic matter described with C/N ratio, improved several years after the cessation of agricultural activity and spontaneous afforestation. The obtained results indicate that silver birch can be used in the stand composition on post−agricultural areas.

    Opis:
    The paper analyses the production and allocation of biomass in young, spontaneoussilver birch afforestation occurring on post-agricultural lands in the Mazowszeregion (central Poland). We investigated 114 sample plots of age varying from 1 to 19 years. During the first 15 years after their establishment on abandoned farmland, the naturally regenerated silver birch stands produced on average approximately 75 tons of dry biomass per hectare. The major (50–70%) part of this biomass was stored in the tree stems and this share increased with age. The fractions of biomass in the foliage and roots decreased over time, while the share of biomass in the branches remained rather constant. The significant age-dependency of the allometric relationships suggested the need to use age-sensitive biomass expansion factors to estimate the biomass from the stem volume.

    Opis:
    Partition coefficients, expressed as logP, were calculated using Advanced Chemistry Development software (ACDlogP) [1] of all combinations of three amino acids (8000 tripeptides). Using our proprietary script, we generated a combination of 8000 tripeptides of 20 amino acids in the FASTA format and, subsequently, full atom Cartesian coordinates were generated. The ACDlogP’s of the generated tripeptides were calculated. Using the Kyte-Doolittle amino acid hydrophobicity scale [2, 3], the value of the correlation coefficients with the calculated ACDlogP values was determined. Hydrophobicity values were assumed as the arithmetic mean of the hydrophobicity of the three amino acids in the tripeptide. Optimisation of the theoretical hydrophobicity scale by minimisation of the correlation coefficient between the calculated ACDlogP values and the hydrophobicity for the tripeptides provided amino acid hydrophobicity; on this basis, the amino acids were divided into 7 groups. The new scale was normalised and implemented using the fuzzy-oil-drop model method to determine the theoretical protein active site of the 1HCK protein based on lipophilic hot spots on the protein surface. The results were compared with the respective results for the Kyte-Doolittle scale and the actual active site with ATP as the ligand.

    Opis:
    Fungi are organisms which occur in the human environment. One of the potential pathogenic fungi is Aspergillus which belongs to mould, and is an etiological factor of non-invasive fungal paranasal sinusitis. Objective. Epidemiological analysis of aspergillosis of the maxillary sinuses. Material and methods. Retrospective analysis of the medical histories of 41 patients treated in the Maxillofacial Surgery Department of Medical University in Lublin, Poland between 2005–2014 due to non-invasive aspergillus maxillary sinusitis. The patients’ gender, age, and etiopathogenesis of the condition with signs and symptoms, and methods of treatment were analysed. Histological examination was crucial in the final diagnosis. Results. The majority of the patients constituted women aged 29–72. The most common complaints were suborbital pain, rhinorrhoea and impaired nasal ventilation. All the patients were treated surgically, and pharmacologically with Fluconazole. Conclusion. Fungal maxillary sinusitis should be taken into account in every case of chronic maxillary sinusitis resistant to standard treatment. Women are more susceptible to Aspergillosis, and the risk factors for the disease are endodontic treatment of the maxillary teeth and fistula antro-oralis post extractionem. Surgical treatment sometimes should be complemented by pharmacological antimycotic treatment.

    Opis:
    Over ninety percent of End Stage Renal Disease (ESRD) patients suffer from anemia due to insufficient endogenous production of human erythropoietin. Until the advent of Recombinant Human Erythropoietin (r-HuEPO) over 30 years ago, patients with ESRD were treated mainly with multiple blood transfusions. The high cost of r-HuEPO in addition to the narrow margin between an effective do-sage and toxicity in drug administration calls for optimal dosage strategy capable of minimizing cost and toxicity while at the same time achieving the desired do-sage outcome. It is well known from control theory that a controller can be de-signed for any plant provided there is readily available a valid model for such a plant. We present Robust Identification procedure, a dimensionality reduction technique capable of capturing the inherent dynamics of anemia patients; conse-quently producing individualized model suitable for robust control synthesis and any other controller design methodologies.
