one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
Background and Objectives: The visceral larva migrans (VLM) is a syndrom observed in human infected with helminth eggs such as the Toxocara spp., that usually infects dogs and cats. Considering the risk factors involved in the occurrence of VLM, particularly important role of these animal populations, this study was conducted to investigate the contamination rate of Toxocara SPP. eggs in the p...
Background and Objectives: Microbial quality, particularly parasitic characteristics in terms of effluent reuse in agriculture is one of the most important indices. The aim of this study is determination of removal efficiency of Kermanshah wastewater treatment(conventional activated sludge) and Gilangharb wastewater treatment plants (stabilization ponds) for cyst and parasitic eggs.Material and...
We tested the hypothesis that a negative fitness-density relationship exists in haematophagous ectoparasites. We studied the effect of flea density on the number of blood meals necessary for starting oviposition and egg production in Xenopsylla conformis and Xenopsylla ramesis when exploiting two rodent hosts, Meriones crassus and Gerbillus dasyurus. The number of blood meals taken by a flea pr...
introduction: the present study aimed to investigate the microbial quality of the produced vermicomposts and compare them with the existing standards. methods: this experimental study was conducted as a pilot-scale one, in the laboratory school. some perishable domestic waste were mixed in a reactor, including food waste, vegetables and fruits, cow manure and sludge of wastewater treatment plan...
background and objective : salmonellosis can be acquired through consumption of infected raw or undercooked eggs. the aim of this study was isolation and identification of salmonella spp from the eggshells and the egg contents samples of tabriz retails. methods : a total number of 150 samples of eggs were analyzed for the presence of salmonella spp. using conventional culture method and multipl...
let $r$ be a commutative ring and $m$ be an $r$-module with $t(m)$ as subset, the set of torsion elements. the total graph of the module denoted by $t(gamma(m))$, is the (undirected) graph with all elements of $m$ as vertices, and for distinct elements $n,m in m$, the vertices $n$ and $m$ are adjacent if and only if $n+m in t(m)$. in this paper we study the domination number of $t(ga...
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
Background and Objectives: Increased environmental concerns about synthetic packaging have promoted developments of novel, environmentally-friendly edible films. In the present study, the quality parameters of chicken egg coated with pectin or pectin incorporated cinnamon hydrosol was assessed. Materials and Methods: Egg chicken were coated with pectin and pectin prepared with cinnamon hydroso...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
