Deoxynivalenol (DON) is one of several mycotoxins produced by certain Fusarium species that frequently infect corn, wheat, oats, barley, rice, and other grains in the field or during storage. It is a toxic byproduct of Fusarium head blight in grains and feeds. Potential human exposure to DON may occur from ingestion of products made from contaminated grains. It has been detected in buckwheat, p...

Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO3 – . Although the export of dissolved organic nitrogen (DON) into the groundwater has been recognized for more than 100 yr, it is often ignored when total N budgets are constructed. Leaching of DON into stream and drinking water reservoirs leads to eutrophication and acidifi cation, and can pos...

using the mean-value theorem for integrals we tried to solved the nonlinear integral equations of hammerstein type . the mean approach is to obtain an initial guess with unknown coefficients for unknown function y(x). the procedure of this method is so fast and don't need high cpu and complicated programming. the advantages of this method are that we can applied for those integral equation...

In this paper, the nutrient distribution, its structural characteristic and controlling mechanism around the Changjiang River estuary during Autumn 1997 and Spring 1998 were discussed, and a clear seasonal variation of nutrient distribution and structure was observed in this area. The concentrations of NO3(-)-N, SiO3(2-)-Si, PO4(3-)-P, DOP, PP and TP in Autumn 1997 were higher than those in Spr...

since the jurisprudential traditions have accepted clearly buying & selling the hunter dogs and there is no available jurisprudential traditions about other species of dogs like as flock, garden and..., many of the jurists don't accept the trading and selling of those dogs. but deliberating upon traditions show that the buying & selling of those dogs is correct and there is no problem. in ...

extractthere are some hypothesis that the children do not feel pain. these assumptions are based on circumstantial and theoretical evidence. this theory believes that children, especially infants are not able to understand the pain because their nervous system is immature. however, these assumptions are acceptable for all of people except about children. there is evidence that children continuo...
