Age, growth and reproduction were investigated for Chondrostoma regium, collected monthly (November 2007- August 2008) from the Dimeh Spring region, Zayandeh Roud River, Iran. The maximum age of collected female and male fish were estimated based on scale increments as five and four years respectively. Von Bertalanffy growth equations were calculated as L_t=246[1-e^(-0.206(t-0.034))], W_t=163.2...

conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...

this study was carried out to determine some biological characteristics including age, growth and somatic condition of carasobarbus luteus and capoeta trutta in the turkish part of the tigris river. the examined samples of c. luteus were distributed between ii-ix years of age. the length-weigth relations of females and males were calculated as log w =-4.7314 +3.0113 log fl and log w = -4.7631 +...

Today we witness the exponential growth of scientific research. This fast growth is possible thanks to the rapid development of computing systems since its first days in 1947 and the invention of transistor till the present days with high performance and scalable distributed computing systems. This fast growth of computing systems was first observed by Gordon E. Moore in 1965 and postulated as ...

With the advent and the rapid growth of the Internet, e-services have proliferated. Indeed, e-commerce activities have played a vital role in expanding current business transactions to much higher levels by allowing a larger number of potential customers and companies to interact in a shorter time with lower costs. E-services include business information, processes, resources, and applications,...

ovarian cancer is one of the major causes of death in women. parabens are a class of chemicals widely used as preservatives in cosmetic and pharmaceutical products, they mimic estrogens, which are known to play a role in the development of different cancers in women. the aim of this study was to investigate the proliferative effects of methyl paraben (mp) and propyl paraben (pp) on human ovaria...

A new method of estimating higher order perturbative coefficients is discussed. It exploits the rapid, asymptotic growth of perturbative coefficients and the information on the singularities in the complex Borel plane. A comparison with other methods is made in several Quantum Chromodynamics (QCD) expansions. Typeset using REVTEX 1 The ordinary perturbative expansions in weak coupling constant ...
