The existing salt mines "Wieliczka" and "Bochnia", where the exploitation of rock salt was going on since 14th century, have recently finished their mining activities. In the rock mass, however, old workings remained. They are often inaccessible and not inventoried properly. Clamping of such workings causes deformations in the rock mass itself and on the surface of the area. The specifics of physical properties of salt rock mass and also the applied exploitation systems influence the course of the deformation process. The complete image of this process also includes the changes of water balance in the rock mass and consequently water suffosion, landslide processes and the movements of the Carpathian Mountains that have not been examined satisfactorily so far. Many years lasting observations of the deformations of the area surface and mine workings allow defining their course and interpreting the obtained results. For the last ten years in order to study deformations the author has applied modern observation techniques: satellite methods (GPS), total stations of high measurement precision, precise leveling, the measurements of the convergence of mine workings and laser scanning. The results have been statistically and geostatistically analyzed. This results in interesting data referring to the course of deformation processes and enables to deal with the problem of securing old workings to minimize the damage.

Among fertilizer ingredients nitrogen is the one noted for biggest losses because its susceptibility to volatilize to the atmosphere and to be leached away from the soil. These losses depend on the level and mode of fertilization. It appears that every year in Poland river waters transport to the Baltic Sea from the whole area about 180 thousand tons of the nutrient. The largest portion of this load is ascribed to agriculture. This study focused on the highland areas, which are commonly seen as a water supplying region owing to the fact that they cover about 35% of water need in the authors＇ country. Specificity of grassland fertilization in these lands is high contribution of natural fertilizers including dunging with fresh manure left by penned animals, particularly by sheep. Authors decided to assess the influence of dunging by folded sheep on meadow nitrogen balance and on its concentration in percolating water. It was demonstrated that a nitrogen balance was highly negative for each object, so the grassland plants supplied their needs in large part with nitrogen from mineralization of soil organic matter. Relatively high loads of nitrogen leached out of the folded objects indicate that nitrogen from mineral fertilizers is better utilized by grassland herbage and thus is much safer for soil and water environment.

In plants, vitamin B6 biosynthesis requires the activity of PDX1 and PDX2 proteins. Arabidopsis thaliana encodes for three PDX1 proteins, named PDXI.1, 1.2, and 1.3, but only one PDX2. Here, we show in planta complex assembly of PDX proteins, based on split-YFP and FPLC assays, and can demonstrate their presence in higher complexes of around 750 kDa. Metabolic profiling of plants ectopically expressing the different PDX proteins indicates a negative influence of PDX1.2 on vitamin Be biosynthesis and a correlation between aberrant vitamin B6 content, PDX1 gene expression, and light sensitivity specifically for PDX1.3. These findings provide first insights into in planta vitamin B6 synthase complex assembly and new information on how the different PDX proteins affect plant metabolism.

采用序半连续反应器就新鲜废水中COD/N比对COD、氮化合物去除效率和微生物生长的影响进行了研究。结果表明,新鲜废水中的COD/N比对COD和总氮去除率有明显的影响。当COD/N比由2.5增至12.5时,COD去除率由44.0%增至75.8%,总氮去除率从63.4%增至99.8%,然而,加料废水中COD/N比对微生物生长没有明显的影响。用一组涉及多个微生物反应的动力学模型,分析了COD/N比对同时去除碳、氮化合物效率和微生物生长的影响。
