Abstract:

Research background: The literature indicates that labor market institutions are determined by cultural, political and economic factors, but does not give explicit conclusions which of these vast group of factors dominates. Purpose of the article: The goal of this study is to empirically assess whether cultural and political factors dominate over economic factors in shaping the labor market institutional framework in the OECD and post-socialist countries. Methods: This framework can be measured by a vast group of indicators. We use 10 such variables that describe the group of 47 po

Abstract:

For about 20 years, standardized soil ecotoxicological tests have relied on the use of an artificial soil substrate (e.g., Organisation for Economic Co-operation and Development; OECD). For both the extrapolation of data obtained in the laboratory to the field situation, as well as the biological assessment of contaminated sites, this approach alone is not sufficient anymore. For this reason a literature review has been performed to investigate the ecological requirements of important terrestrial ecotoxicological test species. The invertebrate species included were Eisenia fetida, E. andrei (e

Abstract:

Abstract An apparatus for measuring biodegradability of metalworking fluids (MWFs) was constructed according to (1), based on the Zahn-Wellens test which enables a continuous determination of CO2 production by the change in conductivity of absorption solution. Results obtained from the testing of 8 different MWFs by this modified method were compared to those obtained in standardized OECD 302 B. The comparison showed better description of bacterial inoculum activity in tested solution; lag phase was easy to indicate.

Abstract:

The dissolution of metal-based engineered nanomaterials (ENMs) in aquatic environments is an important mechanism governing the release of toxic dissolved metals. For the registration of ENMs at regulatory bodies such as REACH, their dissolution behavior must therefore be assessed using standardized experimental approaches. To date, there are no standardized procedures for dissolution testing of ENMs in environmentally relevant aquatic media, and the Organisation for Economic Co-operation and Development (OECD) strongly encourages their development into test guidelines.

While Brazil is at the forefront of global regulation implementation, Brazilian researchers are not always able to transfer certain widely used protocols to their laboratories, particularly protocol

Abstract:

Abstract Objectives Alpinia galanga is a commonly used ingredient in Asian food and traditional medicine. But an extract of the rhizome had never been used commercially in food supplements and functional foods. There is some evidence of safety and tolerability in humans for a proprietary A. galanga rhizome extract (EnXtra™) and it is Generally Recognised as Safe (GRAS) in the US already. However, this botanical ingredient has not been evaluated for its subchronic toxicity in rats to confirm its safety in wider food applications. Methods Sprague Dawley rats were orally administered the test ite

Abstract:

Purpose of the study. Formation of a methodology for systematic evaluation of performance in agricultural tractors. Research methods. The methodological basis for evaluating the performance of agricultural tractors is the OECD Code 2. Code 2 of the OECD standardizes test methods. Determination of traction indicators for tractors is carried out by the method regulated by the SOU L. Pogorslyy UkrNDIPVT 71.2-37-046043090-017:2015. A measuring and registration complex is used. When evaluating the functional accuracy of the tractor, according to DSTU 7463:2013, indicators are analyzed that determin

Abstract:

Background: Health Interview Survey (HIS) collects only self-reported height and weight to estimate obesity prevalence. Because of self-reporting, estimated obesity prevalence could be too low. From 2008 to 2012 an Health Examination Survey/Osservatorio Epidemiologico Cardiovascolare (HES/OEC) has been implemented in Italy with the aim of assessing cardiovascular (CV) risk factors, prevalence of risk conditions and CV diseases for the Italian adult population. Differences in measured and self-reported main anthropometric measures are described. Methods: Random samples of general population str

Abstract:

The kidney plays an essential role in removing waste products and drugs from the body and maintaining balanced body fluids. It gets affected due to many factors, notably, diabetes and high blood pressure. Nowadays, naturally, derived products are essential in curing various ailments and are safe and cost-effective. The purpose of this study is to assess the toxicity profile and nephroprotective effect of a proprietary polyherbal formulation in Wistar albino rats for gentamicin-induced nephrotoxicity. The Polyherbal formulation was procured from Rumi Herbals Private Limited. Acute toxicity expe
