The paper deals with the issue of increasing the potential of the wood-processing sector and increasing its efficiency and competitiveness through the impact of foreign direct investment within the specific conditions of the wood-processing industry in the Slovak Republic. The aim of this paper is the analysis and evaluation of the quantitative and qualitative effects of foreign direct investment in the Slovak Republic and other V4 countries with a specific focus on the wood-processing industry in the Slovak Republic.
Poland remains one of the few countries with nationwide assessment of erosion risk in detailed scales. An existing map of potential water erosion risk was produced in 1980 according to the qualitative method of potential water erosion risk (PWER) indicator, developed by Anna and Czeslaw Jozefaciuk. The potential erosion risk indicator means an erosion thread for the soil without any plant cover and based on only relatively static factors of slope, soil kind (texture) and average annual rainfall, distinguishing five grades of erosion intensity. The indicator provides no information for real and actual state of erosion risk, which depends mostly on the kind of land use. Therefore, an effort has been made to produce a map of actual water erosion risk for Poland, based on the Józefaciuks' methodology for the qualitative indicator of actual water erosion risk (AWER), which includes a land use factor as well as a factor for erosion prevention techniques. The work includes the production of an actual water erosion map based on the digitized map of poten­tial water erosion at a scale of 1:300,000 and CORINE Land Cover 2000 as a source for land use informa­tion. The results show relatively high actual erosion risk in highest intensities: 1.7% of Poland under very strong erosion, 1.0% under strong erosion and 4.4% under average erosion. Compared to potential water erosion, where the same grades cover 17.6% of the country's area, the erosion risk at high grades decreased by 10.5%. According to the land use structure derived from CLC2000, around 2,300,000 hectares show the risk of water erosion in high erosion intensity grades and require erosion control measures.
Effect of dehelminthization on milk yield and milk composition in dairy cows. The aim of this study was to assess the effectiveness of action of selected antiparasitic preparation on milk productivity of cows and milk composition. In coproscopic analyses the qualitative methods by Willis, Żarnowski and Josztowa were used, as well as the quantitative McMaster method. A preparation containing eprinomectin was used for dehelminthization. The study involved100 females after first lactation, which were divided into 2 groups 50 head each: experimental (D) - dewormed in May 2 weeks before going to pasture, control (K) – not dewormed. From the experimental group 15 animals were selected (D1) which were dewormed 2 days before parturition. Analogous group of cows (K1) was selected from the control group (at the same stage of lactation, but not dewormed). It was proved that eprinomectin has a positive effect on milk yield, fat level and dry matter in milk, whereas the effect of this preparation on protein content was not confirmed. It was found that the most favorable time of deworming cows is perinatal period.
Streszczenie. W niniejszej pracy wyznaczono poziomy zawartości ogólnego PCB oraz najbardziej toksycznych kongenerów non-orto (PCB 77, PCB 126, PCB 169) i mono-orto (PCB 114, PCB 156, PCB 157) w wybranych importowanych konserwach z tuńczyka w sosie własnym. Ilościowe i jakościowe oznaczenie badanych związków wykonano metodą kapilarnej chromatografii gazowej, w aparacie GC MSD HP 6890/5973. W większości asortymentów stwierdzono zawartość kongeneru PCB 169. Obliczone równoważniki toksyczności (TEQ) dla badanych konserw wyniosły 10-200 pg-TEQ/kg m.m. Zawartość ogólnego PCB kształtowała się na poziomie 1,4-11,4 μg·kg-1 m.m.
