Background and Aim: Traditional costing systems are not efficient enough to calculate up-to-date costs and analyze training costs in education organizations. The present study was conducted with the aim of establishing an activity-based costing system in Tabriz School of Management and Medical Informatics. Materials and Methods: The current multi-method study was conducted in academic year 201...
The crude methanolic extract of the seeds of Celastrus paniculatus along with its organic soluble fractions were tested for their possible antioxidant and anti-alzheirmer (AD) activity. The extracts showed prominent DPPH free radical scavenging activity, inhibiting activity of authentic peroxynitrite (ONOO-) and inhibition of total reactive oxygen species (ROS) generation. In D...
Organocatalysts have attracted enormous interest in the water-crosslinking reaction in silane-grafted polyolefins (SGPOs) system owing to their simplicity, low toxicity and environmentally benign nature compared to organotin catalysts, which are most used in SGPOs system. We focus on organophosphorus compounds including four structure types as organocatalysts; phosphoric acids, phosphoric ester...
Interaction of fast neutrons with oxygen atoms of cooling water in reactor core leads to the production of 16N isotope which emits 6.13 MeV gamma ray. A system is developed to measure the 16N gamma ray activity using a5.08cm ×5.08cm NaI(Tl) detector. A suitable electronic system is used to count 16N gamma rays in different reactor powers in order to calibrate the 16N system in terms of reacto...
introduction: traditional iranian medicine (tim) is accompanied by little side effects in experience. the mechanisms involved in tim are not much clear. the purpose of this study is assessment of differences of warm and cold nature persons in neuroendocrine system and cytokine pattern (th1/th2) of immune responses. methods: thirty seven 20 to 40 years old male volunteers were divided into 2 gro...
Among immune system components natural killer (NK) cells are the first line of defence against tumor cells. The decreasing activity of these cells can be associated with carcinogenesis, in situ tumor growth and metastasis of different cancers, viral infections, immunodeficiency syndroms and autoimmune diseases. In this study natural killer activity of peripheral blood mononuclear cells (Effecto...
the rose sawfly, arge rosae linnaeus, is one of the most destructive pests of rose bushes in the north of iran. nowadays, many attempts have been made to reduce pesticide application by looking for new methods of pest control. a non chemical method for controlling insect pests including a. rosae can be achieved by using genetically engineered plants expressing carbohydrase inhibitors. therefore...
objective(s): mindium laevigatum is an endemic plant of iran and turkey and is widely used as blood purifier, antiasthma and antidyspnea in traditional medicine. chemical composition of volatile materials of the plant and its antioxidant, antimicrobial and cytotoxic activities were reported in this study. materials and methods: simultaneous distillation-extraction (sde) and gc-mass-fid analysis...
the crude methanolic extract of the seeds of celastrus paniculatus along with its organic soluble fractions were tested for their possible antioxidant and anti-alzheirmer (ad) activity. the extracts showed prominent dpph free radical scavenging activity, inhibiting activity of authentic peroxynitrite (onoo-) and inhibition of total reactive oxygen species (ros) generation. in dpph radical scave...
