cohesion is an indispensable linguistic feature in discourse analysis. lexicald such a differe cohesion and conjunction in particular as two crucial elements to textual cohesion and comprehension has been the focus of a wide range of studies up to now. yet the relationship between the open register and cohesive devices has not been thoroughly investigated in discourse studies. this study concen...
Methods: Four herds which had been subjected to antibiotic use (AU) and three herds that had not been subjected to antibiotics (AF) were selected. From each herd, six pigs from each of four weight groups (4.5, 23, 45, and 109 kg) and five sows were randomly selected for collection of fecal samples. Non-hemolytic Escherichia coli and potential foodborne pathogens, including Salmonella spp. and E...
this survey of salmonella and specifically salmonella enteritidis contamination in broiler flocks carried out in amol as one of the most important poultry breeding centers, used as manure, yolk sac, papers and visceral organs from dead birds. standard cultural methods were used for salmonella isolation. slide agglutination or tube agglutination tests were erformed using salmonella somatic o pol...
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
Salmonella is one of the most serious foodborne pathogenic bacteria in the United States, causing an estimated 1.3 million human illnesses each year. Dairy cows can be reservoirs of foodborne pathogenic bacteria, including Salmonella spp.; it is estimated that from 27 to 31% of dairy herds across the United States are colonized by Salmonella. The present study was designed to examine the occurr...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
Enteric fever, includes typhoid fever caused by Salmonella typhi and paratyphoid fever caused by S. enterica serovar Paratyphi A and is one of the most important febrile illnesses in tropical and subtropical countries, with high rates of morbidity and mortality. S. paratyphi A can be isolated from the blood and feces from paratyphoid fever patients (1, 2). In India, however Salmonella enterica ...
The objective in this study was to assess breed effects in fecal prevalence of Escherichia coli O157:H7 in heifers on a development program in Florida and in their steer half siblings in stocker and feedlot phases in Oklahoma. A secondary objective was to characterize fecal shedding of Campylobacter and Salmonella in subsets of the same samples. After weaning, heifers (n = 501; purebreds and F1...

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
