silver nanoparticles (nps) have been the subjects of researchers because of their unique properties ( e.g., size and shape depending optical, antimicrobial, and electrical properties). a variety of preparation techniques have been reported for the synthesis of silver nps; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods...

abstract  in the wake of renaissance, not only then art and literature pieces but the resulting diverse expressions well reflected the turning revolts in science, philosophy, and politics, and their association which is tremendously clear even among a single artist’s works, e.g. donatello’s sculptures, transparently echoing challenges between old traditions and then new reformations vastly infl...

Objective: Micronuclei are induced in cells by a variety of substances, like UV radiation, infrared rays, X-radiations, and chemicals. Among them tobacco- specific nitrosamines have been reported to be potent mutagenic agents which are thought to be responsible for the induction of chromosomal aberrations resulting in production of micronuclei. The main aim of our study is to compare MN frequen...

for maximum impact, high yielding improved varieties with significant yield advantages must be targeted to farmers and localities that value this trait most. explaining farmers’ demand for yield can serve as a means of targeting the development and dissemination of high yielding varieties. this paper analyzes data collected from 395 farmers in northern ethiopia using a zero-limit tobit regressi...

The complexity of planning tasks have increased over the past decade. There is relatively poor understanding what the implications are of increased task complexity in planning and scheduling operations. Previous work in the behavorial sciences have investigated the concept of cognitive load, addressing both task complecity and task workload or stress, and have concluded that decision makers ten...

Background: Pemphigus diseases including pemphigus vulgaris (PV) and bullous pemphigoid (BP) are autoimmune diseases that cause severe blistering of the skin and mucous membranes. Among inflammatory mediators, reactive oxygen species (ROS) are involved in the pathogenesis of a wide variety of diseases through oxidative stress for which protein carbonyl (PC) and total antioxidant capacity (TAC) ...
