Water environment monitoring is an important way to optimize the allocation and sustainable utilization of regional water resources beneficial for ensuring security resources. In order explore hydrochemical distributions in a mountain–oasis ecosystem Central Asia, surface groundwater samples from Kaidu River basin were collected over four seasons. pH values, major ions, total dissolved solids (...

Water is a very important vital resource for all living organisms. A world without water can not be imagined. However the world is running out of its most precious resource. Water resources must be protected completely before the end of life on Earth, so today management of water resources has become the main agenda topic globally. Effective protection can be provided by sustainable water manag...

Yersinia enterocolitica strains of serotypes lethal to mice have been reported previously to produce an endogenous siderophore. In this study, an ethyl acetate-extractable siderophore was characterized and given the name yersiniophore. Yersiniophore was produced by 16 of 16 human isolates of serotypes O:4, O:4,32, O:8, O:21, and one nonhuman isolate of serotype O:21. It was not produced by isol...

Using Ecological Floating Bed (EFB) to purify polluted water is a process of ecological restoration at virgin position, as well as a complicated physical, chemical and biological process. Its core is utilizing aquatic plants and root’s microbes to absorb nitrogen and phosphorus elements, degrade organic matter and enrich heavy metal. EFB has been applied to some water pollution control projects...

Terrestrial ecosystems are often considered as among the structurally most complex systems that can be scientifically investigated. On the other hand, utilization techniques like forestry or water management, focussing on specific functional aspects, often follow relatively simple empirical rules, which led in the past to satisfying predictions. This apparent contradiction opens the question wh...

OBJECTIVE To determine the effect of intensive patient-centered management (PCM) on service utilization and survival. STUDY DESIGN Prospective cohort study of 756 patients in California who had a life-limiting diagnosis with multiple comorbid conditions (75% were oncology patients) and who were covered by a large commercial health maintenance organization from February 2003 through December 2...

Water reservoir programming studies aim to determine the final cultivated land area based on predefined agricultural models and water requirements. Dam utilization rule curve is also provided in such studies. The system of Dez dam water resources was simulated applying the basic information in order to determine the capability of its reservoir to provide the objectives of the performed plan. As...

one of the core elements of water management and increase agricultural productivity is the efficient use of available resources. due to increasing demand for agricultural products, increase the productivity of scarce resources is essential. optimal utilization of these resources, in addition to meet the demand of the community as a major goal, can also increase operating income to be followed. ...
