In this research, acute toxicity (LC) of zinc oxide nanoparticle on Beluga (Huso huso) andcommon carp (Cyprinus carpio) was studied. The experiment was conducted using theOrganization for Economic Co-operation and Development (No. 202) method. For bothspecies, 96hLC10 was determined to be more than 200 mg/l. To assess the effects of zinc oxidenanoparticles on blood factors, leukocyte index coun...

staphylococcus aureus, as one of the main agentsfor hospital infections,is considered as highly important because they show resistance to a wide range of antibiotics.resistance to selective antibiotics such as vancomycin is a serious problemin the medical community; thus it seems rational to use alternative substances for treating these bacteria.the aim of this study isto investigate the preval...

The effective removal of dyes from aqueous wastewaters is among the most important issues formany industrialized countries. Removal of Congo Red (CR) dye from aqueous solutions was studiedusing nickel oxide nanoparticles. The operating variables studied were initial pH of solution,adsorbents dosage, temperature and contact time. The morphological information of nickel oxidenanoparticles were ch...
Background and purpose: The aim of this study was to evaluate the efficiency of zinc oxidenanoparticles (ZnO NPs) in combination with US-H2O2 advanced oxidation processes (AOPs) for the removal of antibiotic amoxicillin (AMO) from aquatic environment. Materials and Methods: This experimental study was conducted in a batch reactor system. The effect of the parameters, such as pH (3-8), the dose...

مسایل تصمیم گیری با محدودیت به دلیل کاربردشان هم در حوزه های علمی و هم در صنعت و تجارت، مورد توجه قرار گرفته است. در مواجهه با این مسایل باید دو گام اساسی برداشته شود: ایجاد مدل و حل آن. این مسایل عمدتا پیچیده هستند و اغلب یافتن یک مدل مناسب برای آن ها مشکل است. از طرف دیگر فضای جستجوی آن ها بزرگ است و به صورت نمایی با سایز مساله رشد می کند. پس باید برای حل آن ها از روش های کارایی استفاده شود ک...
