Opis:: Conservation farming practices using the least soil disturbance and straw-return benefits the crop agronomic attributes and soil nutrient accumulation. The four-year (2016-2019) research was conducted under randomized complete blocks design to explore the agronomic benefit of conservation tillage practices on wheat yield performance and on soil fertility parameters. The two straw treatments consisted of wheat straw-return to the notilled soil and straw incorporation into the conventionally tilled soil. The two tillage treatments were the no-tillage and conventional tillage control. These conservative tillage treatments were compared with the conventional tillage control. In comparison with conventional tillage, the conservation management practices of no-tilled soil, conventionally tilled soil, and no-tillage notably increased the yield by an average of 33, 26, and 18% respectively. Moreover, conservative tillage practices improved the soil nitratenitrogen, ammonium nitrogen and carbon contents in the 0-30 cm soil layer by 12, 9, and 15% respectively over conventional tillage, averaged across conventionally tilled soil, no-tilled soil, and no-tillage. The overall distribution of soil nitrate-nitrogen, ammonium nitrogen, and carbon in the 0-30 cm soil layer with regard to conventionally tilled, no-tilled soil, and no-tillage was greater than conventional tillage, based on Principal Component Analysis. We concluded that conservation tillage practices could replace conventionally tilled practice with respect to productivity, soil mineral nitrogen, and carbon accumulation benefits.

Opis:: Human cystatin C (HCC) shows a tendency to dimerize. This process is particularly easy in the case of the L68Q HCC mutant and might lead to formation of amyloid deposits in brain arteries of young adults. Our purpose was to find ligands of monomeric HCC that can prevent its dimerization. Eleven antisense peptide ligands of monomeric HCC were designed and synthesized. The influence of these ligands on HCC dimerization was studied using gel electrophoresis and molecular modeling methods. The results suggest that all the designed peptides interact with monomeric HCC facilitating its dimerization rather than preventing it.

Opis:: Imidazoacridinones (IAs) are a new group of highly active antitumor compounds. The intercalation of the IA molecule into DNA is the preliminary step in the mode of action of these compounds. There are no experimental data about the structure of an intercalation complex formed by imidazoacridinones. Therefore the design of new potentially better compounds of this group should employ the molecular modelling techniques. The results of molecular dynamics simulations performed for four IA analogues are presented. Each of the compounds was studied in two systems: i) in water, and ii) in the intercalation complex with dodecamer duplex d(GCGCGCGCGCGC)2. Significant differences in the conformation of the side chain in the two environments were observed for all studied IAs. These changes were induced by electrostatic as well as van der Waals interactions between the intercalator and DNA. Moreover, the results showed that the geometry of the intercalation complex depends on: i) the chemical constitution of the side chain, and ii) the substituent in position 8 of the ring system.

Opis:: W artykule przedstawiono uproszczoną metodę wyznaczania ilości ciepła do ogrzewania i chłodzenia budynku zbudowaną w oparciu o analogię elektryczną modelu skupionej pojemności cieplnej. Podstawą modelu nieustalonego procesu wymiany ciepła pomiędzy budynkiem i jego otoczeniem jest układ 5R1C, którego zachowanie się opisuje równanie różniczkowe zwyczajne. W pracy przedstawiono metodę rozwiązania równania tego modelu przy zmiennych warunkach brzegowych zmodyfikowaną metodą Eulera, która wraz z metodą superpozycji układu liniowego w pojedynczej chwili czasu prowadzi do równań uproszczonej godzinowej metody dynamiki cieplnej budynku.
This paper presents the basis of 5R1C model of building heat exchange with the outer environment. The lumped capacitance method used for whole building is utilized to get equations of simply 5RIC hour method. This method can be used for calculation of heat and cool demand for building and is adopted in Poland for determining energy performance class for nonrcsidential buildings as required by HU Energy Performance Building Directive. The article was written due to the support of STEP Project PL 0077 financed by a grant from Iceland. Liechtenstein and Norway through the EEA Financial Mechanism and the Norwegian Financial Mechanism
