BACKGROUND The heterocyclic hydrazones constitute an important class of biologically active drug molecules. The hydrazones have also been used as herbicides, insecticides, nematocides, redenticides, and plant growth regulators as well as plasticizers and stabilizers for polymers. The importance of the phenolic quinolyl hydrazones arises from incorporating the quinoline ring with the phenolic co...

In order to improve our understanding of the origin and production processes methylamine in atmosphere its contribution particulate WSON, simultaneous measurements size-segregated aerosols gas phase were conducted at a forested site Yamanashi Prefecture, Japan, over one year. The concentration atmospheric that is sum phase, coarse-mode, fine-mode particles was 0.962 ng-N m−3 on average. About 7...

one determinant of peace is the role of women in society. some studies suggest that a young age structure, also known as a “youth bulge” can facilitate conflict. population growth and age structure are factors amenable to change in a human rights context. we propose that policies which favor voluntary family planning and the education of women can ameliorate the global burden of disease associa...

The effect of pH value and different kinds anions on the corrosion behavior Cu/Al casting-rolled clad plates in alkaline solution was evaluated by means scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), weight loss analysis, 3D confocal laser (CLSM) electrochemical test. Results show mainly occurs aluminum side. resistance decreases as increases....

water quality is a worldwide problem which affects human beings lives fundamentally. water scarcity is intensified in result of quality deterioration. different factors such as population increase, economic development and water pollution could be considered as the origins of the problem. the study and forecasting of water quality is necessary to prevent serious water quality deteriorations in ...

A particular river-whiting phenomenon occurred in the early 2000s in the Xiaoche River and since then it has been reoccurring from June to November each year. Residents were surprised by this phenomenon and worried about it. This study was designed to reveal the forming mechanism of the river-whiting phenomenon. A comparison of T, EC, ORP, DO, TDS and δ34S in the culvert water and discharge pip...
