چکیده مقاله:

Background: Municipal waste incineration are one of the largest resources of 2,3,7,8- tetrachlorodibenzo-pdioxins (TCDDs) and Polychlorinated dibenzofurans (PCDFs) from incineration ends up in water and food cycle are taken up by fish and etc. These gaseous emission products tend to give rise to concern due to their carcinogenic potential, as well as their potential adverse health effects on reproduction. Materials and Methods: The study was carried out to compare SPSS ver 16. , and Arc GIS, to put emphasis on the effects of residing in proximity to several municipal resources. The risk seems to be greater for human who worked near incinerators though it is very difficult to discriminate between the effects of the indoor air and those of other resources of municipal pollution. Results: The major result was that the cancer risk form TCDDs emissions from the MWI was extremely low, i.e., about 1000-fold below that calculated for PCDFs emissions from other resources in the same area. The TCDDs emissions were reported to be in the range of 18.32 ng I-TEq/m3.The study does not contain any data on the levels of TCDDs in ambient air, soil or in the blood or adipose tissue derived from residents of the various areas or from cancer patients. Conclusion: We conclude that men who worked in indoor waste terminals have sperm counts less than half as high as their grandfathers had at the same age. In addition, the occurrence of cancer in the testicles has increased 3-fold to 4-fold during the past 45 years; and various birth defects of the male reproductive system have increased 2- fold to 4-fold during the same period. Thus breast cancer, testicular cancer, and defects of the male reproductive system. Trimming fat from meat and consuming low fat dairy products may decrease the exposure to TCDDs and PCDFs compounds.

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
