background fenton (fe2+ and h2o2) and modified fenton (fe3+ and h2o2) are two popular methods used in advanced oxidation processes (aop) and degradation of persistent organic pollutants (pops), such as dye compounds. in these processes, fe2+ and fe3+ as catalysts and h2o2 as the oxidizing agent are added to the reactor. objectives the aim of the current study is to assess the abovementioned met...

background and objectives: discharge of wastewater from textile dyeing industries has been a problem in terms of pollution and treatment of these waters is a great task. keeping this in mind, the aim of our current research is to study the effect of various bioprocess variables on decolorization of an azo dye, congo red, by a fungal isolate, aspergillus niger hm11. materials and methods: centra...

background: colors make many problems and these are major sources of environmental pollution. therefore, this wastewater should be treated before discharge to environment to reduce the environmental threats. adsorption is one of the usual processes for color removal from wastewater. nanotube s are new adsorbents with extend application for adsorption of different compounds. aim of this study wa...

bacterial diseases have been reported to be the major limiting factor in shrimp production. the use of natural products such as antimicrobials has been reported as a solution to the problem. the crude extract of a red seaweed laurencia snyderiae obtained from the persian gulf was evaluated for shrimp growth performance and to determine in vivo efficacy of this seaweed in the prevention of shrim...

introduction red beans (phaseolus vulgaris l.) with 22-25 % protein and 50-60 % carbohydrates are one of the most important legumes in the world, particularly in some developing countries. it is one of the major sources of vegetable protein. with regard to increasing population and increasing the need of protein, the use of plant resources like red bean with a large amount of protein is growing...

abstract in order to study the effects of quantitative and qualitative traits on cooking characteristics and protein percentage of 15 red bean genotypes, a randomized complete block design was conducted with three replications in normal irrigation and drought stress. these traits were measured in farm and nutrition laboratory employing international standard of ciat. analyses of variance showed...

introduction: in a prospective study, we aimed to assess the value of enhanced rdw to predict sepsis and evaluate factors affecting length of icu stay and in-hospital mortality among sepsis patients. material and method: after exclusion of 27 patients, we included 160 adult patients with suspicious sepsis admitted at university affiliated hospital with 33 icu-beds from 2010 to 2012. nighty pati...

due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. in thecurrent study, nine sandstone samples from the upper red formation (specified by the letters a, b, c, cg, s, s1, sh, tr and min)were studied from a petrophysical point of view and their durability was evaluated. then, their suitability as building stones wasassess...
