Synthesis of photoreactive solvent-free acrylic pressure-sensitive adhesives in the recovered system

The present paper discloses a novel photoreactive solvent-free acrylic pressure-sensitive adhesive (PSA) systems, especially suitable for the so much adhesive film applications as the double-sided, single-sided or carrier-free technical tapes, self-adhesive labels, protective films, marking and sign films and wide range of medical products. The novel photoreactive solvent-free pressure-sensitive adhesives contain no volatile organic compounds (residue monomers or organic solvent) and comply with the environment and legislation. The synthesis of this new type of acrylic PSA is conducted in common practice by solvent polymerisation. After the organic solvent are removed, there remains a non-volatile, solvent-free highly viscous material, which can be processed on a hot-melt coating machine at the temperatures of about 100 to 140°C.

Strongyloidiasis and hookworm infections are neglected helminth diseases widespread in tropical and subtropical areas. In humans, particularly in immunocompromised patients infections potentially may lead to the life-threatening clinical conditions involving the respiratory as well as gastrointestinal systems. The increased number of tourists travelling to tropical regions is associated with more frequent infection with parasites such as Strongyloides and hookworm. The infection takes place when filariform larvae penetrate the skin exposed to soil, than migrate through the lungs and finally reach the intestine. Travelers are often not aware of how they could get infected. Physicians may suspect strongyloidiasis and hookworm infections in tourists with diarrhea returning from endemic areas, especially when an elevated eosinophilia is observed. In the literature there are many reports about the presence of parasites in indigenous communities, but very few are available regarding travelers. This paper describes a dual infection with hookworm and Strongyloides stercoralis in a young female tourist returning from Southeast Asia. To our knowledge, this is the first report of hookworm and Strongyloides stercoralis infection in a tourist from Europe, acquired in an endemic area.

The study was conducted in the area of the impact of sulfur mine in Jeziórko. The aim of the study was to assess changes in pH, cation exchange capacity and content of available phosphorus, potassium and magnesium after 6 years of conducting remediation. In the experiment (plots with an area of 15 m2) degraded soil was rehabilitating by post-floating lime and compost from sewage sludge, sewage sludge and ash from combined heat and power (CHP). Composts at a dose of dry matter 180 t · ha-1 (6%), were determined in accordance with Minister of the Environment Regulation from 2001, applied the following options: control (only native soil limed), compost from municipal sewage sludge, sewage sludge compost (80%) and ash (20%), compost from sewage sludge (70%) and ash (30%). The reclaimed plots were sown with mixture of rehabilitation grass. Single de-acidification, land fertilization and a further 6-year extensive (without fertilization) use had a different influence on the properties of the native soilless substratum. Irrespective of the reclamation manner, after six years land use in the upper layers, observed increase in the average content of available phosphorus, available potassium content does not changed significantly but recorded a tenfold decrease in the content of available magnesium.
