this study introduces the differential transform method (dtm) to analyse the free vibration response of a rotating, closed section, composite, timoshenko beam which features material coupling between flapwise bending and torsional vibrations due to ply orientation. the governing differential equations of motion are derived using hamilton’s principle and solved by applying dtm. the natural frequ...
the mechanisms of drug dependence and rewarding properties of opiates are not exactly known and several neurotransmitters seem to be involved. it is possible that the rennin-angiotensin system could interact with the opioid system, since it has been shown that angiotensin ii(ang) and ace inhibitors have analgesic, anticonvulsant and antidepression effects and in some cases they could antagonize...
introduction: our previous study has showed that chronic administration of magnesium oxide nanoparticles (mgo np) can reduce anxiety in adult male rat. in this study the effects of mgo np on anxiety induced by morphine withdrawal were investigated in adult male mice. methods: adult male nmri mice (weighing 27 ± 3 g) divided into groups: control, receiving intraperitoneal (i.p.) injection of mgo...
background: matricaria chamomilla (mc) contains flavonoids such as apigenine which exerts benzodiazepine-like activity, therefore it may be helpful for morphine withdrawal syndrome treatment. in this study the effects of peripheral (ip) injection of mc hydroalcoholic extract was investigated on morphine withdrawal syndrome signs in rats. material &methods;: 24male wistar rats (200-250gr) were a...
Background: High levels of fatigue in the workplaces can lead to reduced productivity, and increase the risk of accidents and injuries. Purpose of this study was to assess and compare the fatigue levels among fixed-dayshift and rotating-shift workers of a rolling mills and steel production company in tehran. Methods: The study included 180 workers with fixed- and rotating-shift schedules. The ...
We present a numerical study of the rotating flow generated by two rotating disks in co-/counter-rotating, inside a fixed cylindrical enclosure similar to the Czochralski configuration (Cz). The enclosure having an aspect ratio A = H/Rc equal to 2, filled with a low Prandtl number fluid (Pr = 0.011), which is submitted to a vertical temperature gradient. The finite volume method has been used ...
Objective: The purpose of the present study was to compare addiction memory intensity and self-control in successful and unsuccessful addiction withdrawal. Method: In this causal-comparative study, the population of the study consisted of male addicts who referred to Rasht addiction treatment clinics (District one) in 2018. Among them, 45 individuals with successful addiction withdrawal (more t...
The purpose of this research was to suggesting a model of factors affecting on promoting the resilience of rotating staff in Iranian Oil Terminals Company. This research was conducted using qualitative method and thematic analysis based on inductive and need-based method. The statistical population of this research was the rotating staff of Iranian Oil Terminals Company. The statistical populat...
Abstract Background: Long-term use of opioids has acute effects on homeostasis of the body. Discovering the impacts of opioids on hematological parameters of narcotics withdrawal and dependents blood may be helpful in recognizing the homeostasis condition of their body for the useful treatment. Methods: In this study a cross-sectional method was applied. The abusers of opium and her...
