This study provided data that can be used to discriminate asbestiform and non-asbestiform amphiboles contained in landscaping rocks recreational parks. The length width of fibers being at least 5 μm long with a minimum aspect ratio 3:1 were measured using transmission electron microscope compared an asbestos reference sample. park samples thicker than 1 (average 1.9 μm), while the Health Safe...

background: residents of the northeastern region of iran experience high mortality rates from esophageal squamous cell carcinoma (escc). one etiologic factor might be exposure to high levels of polycyclic aromatic hydrocarbons, including benzo(|î±|)pyrene (bî±p). we examined whether food or water are the major sources of bî±p exposure in this population. materials and methods: we used a dietary...

background: colorectal adenocarcinoma is one of the most prevalent and treatable malignancies of the gastrointestinal tract. pattern of expression of the p53, p21, p16, e-cadherin and |î²|-catenin proteins are shown to be related to the prognosis of this malignancy. we aimed to compare the pattern of expression of these proteins in tumoral and nontumoral mucosal cells of cancer and on-cancer pa...

In this paper we study to solve the o f additive (β1,β2)-f unctional inequality with n−variables and their Hyers-Ulam stability. First are investigated in complex Banach spaces a fixed point method last direct method. I will show that solutions of mapping. Then Hyers−Ulam stability these equation given proven. T hese main results .
