In recent years, the volcanic activity of Changbai Mountain has been accompanied by several earthquakes, and frequent human engineering activities have led to a gradual increase in number collapses region, which severely impacts residents’ lives property safety. northeastern China, area southeastern Jilin Province is typical mountain environment. This paper selects 12 evaluation indicators buil...

The quality of exposure assessment is a major determinant of the overall quality of any environmental epidemiology study. The use of biomonitoring as a tool for assessing exposure to ubiquitous chemicals with short physiologic half-lives began relatively recently. These chemicals present several challenges, including their presence in analytical laboratories and sampling equipment, difficulty i...

Forty-six Hereford heifers were slaughtered at different stages of gestation. Udders and gravid uteri were removed. Each gravid uterus was dissected into fetus, fetal membranes, fetal fluids and uterus. Fresh weights, dry matter, ether extract, ash, nitrogen and gross energy contents of the various tissues were determined. Weights and compositions of udders and uteri from 36 non-pregnant heifer...

The article discusses the meaning and content of concept nothingness introduced by S.S. Neretina in book "The Earth Hums with a metaphor". Philosophy Literature" (short story "Lermontov: semantics repetitions"). author identifies five main characteristics this view: nothing as freedom (where is understood "as peace, silence, love – "I"); balancing on verge being non-being; an opportunity to exp...

The primary purpose of this Interaction Profile for carbon monoxide, formaldehyde, methylene chloride, nitrogen dioxide, and tetrachloroethylene is to evaluate data on the toxicology of the “whole” mixture and the joint toxic action of the chemicals in the mixture in order to recommend approaches for assessing the potential hazard of this mixture to public health. To this end, the profile evalu...

There are several pieces of legislation based on human health assessment that set the framework for U.S. EPA's regulation of water contaminants, such as bromate. The Safe Drinking Water Act, for example, specifies that the best available science be used in support of regulation of drinking water contaminants, and highlights that regulations must provide protection to sensitive human populations...

A question like “Does life have meaning?” is a comprehensive question about our life and value. This inquiry changes into “How do we have to live our life?” or “If there are purposes in our life, what are we aiming for?”(Nielsen, 1980). The query of meaning in life is often evoked by the incident and experiences in the world and arises when we encounter various failure, misfortune, woe, sufferi...

The EFSA Panel on Plant Protection Products and their Residues (PPR) has developed, as a self-task mandate (EFSA-Q-2019-00100), two adverse outcome pathway (AOP)-informed integrated approach to testing assessment (IATA) case studies answer developmental neurotoxicity (DNT) hazard identification characterisation problem formulation that could support the regulatory decisions for pesticide active...

This report provides a state-of-the-art review of available computational models for developmental and reproductive toxicity, including Quantitative Structure-Activity Relationship (QSARs) and related estimation methods such as decision tree approaches and expert systems. At present, there are relatively few models for developmental and reproductive toxicity endpoints, and those available have ...

Most professional women step off the career fast track at some point. With children to raise, elderly parents to care for, and other pulls on their time, these women are confronted with one off-ramp after another. When they feel pushed at the same time by long hours and unsatisfying work, the decision to leave becomes even easier. But woe to the woman who intends for that exit to be temporary. ...
