Many states have passed legislation that regulates agricultural P applications based on soil P levels and crop P uptake in an attempt to protect surface waters from nonpoint P inputs. Phytase enzyme and high available phosphorus (HAP) corn supplements to poultry feed are considered potential remedies to this problem because they can reduce total P concentrations in manure. However, less is know...
A potential biomarker for early diagnosis of cancer is assessment of high nuclear DNA content. Conventional hematoxylin staining is neither stoichiometric nor reproducible. Although feulgen stain is stoichiometric, it is time consuming and destroys nuclear morphology. We used acidic thionin stain, which can be stoichiometric and also preserve the nuclear morphology used in conventional cytology...

Mice were inoculated with St. Louis encephalitis (SLE), Flanders (FLAN), California (CE), or Tensaw (TEN) viruses. At fixed intervals after inoculation, brains from these mice were coUected and assayed for infective virus and complement-fixing, hemagglutinating, and precipitating antigens. Detectability of these antigens was correlated with the appearance of signs of illness in the mice. Infect...
abstract the proper management of a watershed depends on recognition of effective elements and investigation of their behavior in different conditions. till date, many researches have studied the role of topographical general characteristics on hydrologic behaviors. whereas, the changeability of hydrologic properties under different conditions, especially in iranian watershed has been rarely ta...
