background: colorectal cancer (crc) is the third common malignancy all over the world. modern life styles affecting nutritional habits have been providing a potential impact on crc. this study aims to assess the nutritional characteristics in crc patients of golestan province, northeast of iran. methods: all incident crc cases (n=47) in northeast of iran (2004-2005) and a matched number of heal...

Within the framework of QED we investigate the inclusive J/ψ production at ee colliders. It is expected to be as a further test to the charmonium production mechanisms and QED. We find that at the energies of CESR, BEPC, and TRISTAN (e.g. 4.0GeV ≤ √s ≤ 60GeV ), the contributions of the concerned electromagnetic processes to the J/ψ inclusive production are great, even dominant, thus they greatl...

Recently, Belle and BaBar Collaborations observed surprising suppression in the endpoint J/ψ spectrum, which stimulates us to examine the endpoint behaviors of the e + e − → J/ψgg production. We calculate the J/ψ momentum and angular distributions for this process within the framework of the soft-collinear effective theory (SCET). The decreasing spectrum in the endpoint region is obtained by su...

‎ Let $(X,d)$ be a metric space and $Jsubseteq (0,infty)$ be a nonempty set. We study the structure of the arbitrary intersection of vector-valued Lipschitz algebras, and define a special Banach subalgebra of $cap{Lip_gamma (X,E):gammain J}$, where $E$ is a Banach algebra, denoted by $ILip_J (X,E)$. Mainly, we investigate $C-$character amenability of $ILip_J (X,E)$.

avian leukosis virus subgroup-j (alv-j). mycoplasma gallisepticum (mg) and mycopjasma synviae (ms) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. seven broiler grandparent flocks of iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to alv-j, mg, and ms by...

This paper is an attempt to prove the following result:Let $n>1$ be an integer and let $mathcal{R}$ be a $n!$-torsion-free ring with the identity element. Suppose that $d, delta, varepsilon$ are additive mappings satisfyingbegin{equation}d(x^n) = sum^{n}_{j=1}x^{n-j}d(x)x^{j-1}+sum^{n-1}_{j=1}sum^{j}_{i=1}x^{n-1-j}Big(delta(x)x^{j-i}varepsilon(x)+varepsilon(x)x^{j-i}delta(x)Big)x^{i-1}quadend{e...
