Free radicals are an important part of reactive oxygen species (ROS). Their presence is essential for proper cell function. If present in moderate amounts, they act as signalling messengers in numerous cellular processes such as cell proliferation, differentiation, migration, as well as cell-cell communication. However, excessive ROS accumulation leads to oxidative stress inducing cell damage a...

Dam construction causes the accumulation of phosphorus in the sediments of reservoirs and increases the release rate of internal phosphorus (P) loading. This study investigated the longitudinal variability of phosphorus fractions in sediments and the relationship between the contents of phosphorus fractions and its influencing factors of the Manwan Reservoir, Lancang River, Yunnan Province, Chi...

Tomatoes (Solanum lycopersicum) plant were provided with bio-fertilizers issued from anaerobic digestion of olive mill wastewater without and 1%, 5% phosphate residues in mesophilic conditions for 25 days. 1% raw substrates (OMW raw; OMW + 1%PR 5%phosphate residues) digestates (olive digestate, 1%phosphate digestate digestate) was fortnightly to the plants. Reclaimed water a treatment located s...

three hundred twin births from a hospital in tehran, iran have been analyzed for seasonal variation at birth and physical measurements. the results show that the highest twinning rates for mm (5.61), ff (7.73) and mf (5.36) were seen in april, january and september, respectively. the four physical measurements at birth showed non-significant differences among the male and female twins, but mm a...

a experiment was lay out in order to evaluate the effects  of different biofertilizers on yield and yield components of maize at the lorestan provience, iran. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitrokara (n1), o4 (n2), o6 (n3) and control (n4)) and three phosphate biofrtilizers (phosphate barvar2 (p1), biozarr (p2), mc1+p...

studies show that any complications including hemorrhage, lack of blood supply, lack of oxygen supply, and death of cells in a tissue, will have a clear effect on electrical properties of that tissue. thus, by measuring impedance of a set of tissues, potential problems of the damaged tissue may be found. since electrical impedance is closely related to the measuring frequency, obviously, every ...

The purpose of current investigation was to explore the scope integrating an anaerobic digester in a decentralized municipal wastewater treatment plant for in-situ household waste. present work intends identify potential sewage sludge and food waste biogas generation. study conducted lab scale continuous stirred tank reactor having working volume 6.5 L at mesophilic temperature. paper mill used...

introduction: birth weight is one of the important sanitary indices in evaluating the prenatal care all over the world. the purpose of this research was to determine the relationship between the bio-environmental characteristics of mothers with infant’s birth weight. materials and methods: in corrolation study, first, all newborn babies in hospitals and maternity centers khuzestan between farwa...

In the current state of huge waste production and energy crisis, there is a need to find additional alternate resources options for management. The present study was designed measure potential different fruit wastes serve as substrate lipid accumulation in oleaginous bacteria. For this purpose, three novel bacterial strains (AF3, KM1 KM10) isolated from crude oil samples were systematically com...

Replacing conventional plastics with bioplastics, i.e., that are bioderived and/or biodegradable, does not necessarily solve the issues of resource depletion and plastic waste accumulation. To come to a truly sustainable economy, growing bioplastics production must be paralleled effective end-of-life strategies for bioplastic waste, which is essential all regardless their biodegradability. Whil...
