Current state of water resources in byelorussian Polessie and ecological risks

Busko E. G., Volchyek A. A., Tanas W., Szymanek M.

Journal of Research and Applications in Agricultural Engineering

2014

Vol. 59, nr 2

The article below covers problems associated with water resources in Byelorussian Polessie. Qualitative and quantitative evaluations of surface waters of the major streams in the region are proposed. Also, possible consequences of river run-offs due to climate changes are discussed. Immediate challenges facing those researchers who deal with water problems of Polessie are outlined.

W artykule przedstawiono analizę problemów związanych z wodnymi zasobami Białoruskiego Polesia. Przeprowadzono ilościową i jakościową ocenę wód powierzchniowych głównych rzek regionu. Rozpatrzono możliwe skutki zmian rzecznych spływów w wyniku zmiany klimatu i ich wpływ na środowisko rolnicze. Określono główne cele badań prowadzących do rozwiązania wodnych problemów Polesia.

Qualitative evaluation of protective fabrics

Cybulska M., Snycerski M., Ornat M.

Autex Research Journal

2002

Vol. 2, no. 2

Protective garments are designed to meet the dual needs of product/process protection and workers' safety and comfort. In this paper, a qualitative evaluation of woven protective fabrics has been presented. The fabric parameters which are most important from the point of view of the user's needs have been selected and analysed. Basic mechanical parameters such as breaking load, elongation at break and tear resistance were determined in certain example fabrics before and after the washing and sterilisation processes. The worker comfort was analysed by determining air and water vapour permeability and surface resistance. The barrier properties of fabrics were analysed by determining the efficiency of filtration and fabric porosity. The durability of fabrics was evaluated in respect of their ability to stand up to the washing and sterilisation processes, and of the analysis of fabric structure deformation under external loading.
