background: doxorubicin (dox), an anthracycline antibiotic, is a widely used anticancer agent. in spite of its high antitumor efficacy, the use of dox in clinical chemotherapy is limited due to diverse toxicities, including gonadotoxicity. objective:  we investigated the protective effect of nano-zinc oxide (nzno) as an established antioxidant on dox-induced testicular disorders. materials and ...

background: it has been shown that zinc has an effect on physiological responses in animals and birds. on the other hand, dietary phytase in poultry results in increased availability of zinc. objectives: this study was conducted to investigate the effects of zinc oxide (zno) and escherichia coli-derived 6-phytase supplemented diets on the plasma metabolites and enzyme activities of broiler bree...

The friction coefficient of a specific material combination is often assumed to be invariant in manufacturing processes such as during the tightening threaded fastener joints. This paper considers impact storage conditions on friction. Fasteners were stored hot humid and sub-zero temperature study thread under-head contacts. Four Zn-flake coatings, commonly used automotive industry considered. ...

Through the microwave assisted fast synthesis method, Zinc Magnesium Oxide nanocomposite was prepared. Zinc Magnesium Oxide nanocomposite heated at 500oC was used for further structural, optical and antibacterial studies. The Debye Scherrer equation was used to calculate the average particle size of the nanocomposite. The optical characterization of the oxide nanocomposite was carried out by UV...

This paper presents the fabrication and characterization of zinc oxide micro-flowers and their antibacterial activity. The micro-flowers of zinc oxide composed of hexagonal nanorods have been prepared via solution process using precursor zinc acetate di-hydrate and sodium hydroxide in 3 h of refluxing time at ~90°C. The antibacterial activities of grown micro-flowers were investigated against f...

background : incidence of  white  spots due  to  demineralization of  enamel  and  gingival problems  is  an  unacceptable  result  of  orthodontic  treatment.  plaque  accumulation  and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...

Interocclusal records are an everyday necessity in routine prosthodontic practice. A number of materials have been advocated by several groups of workers over a length of time to be suitable for the purpose. In the present study, the accuracies exhibited by four commonly used interocclusal recording materials were compared when they were subjected to both the clinical and laboratory phases of j...

This talk concerns simulations of fermionic systems at non-zero density, which don’t suffer from the problems associated with gauge theories. To paraphrase the sub-title of the workshop, they could be described as “not-quite-so complex systems with a real action”; however, as I propose to show, the physics involved is still rich. The two theories I will discuss are referred to as “Gross-Neveu” ...
