introduction: addiction is a habit or behavior that is often hard to quit. it is estimated that 190 million persons are substance users around the world. substance abuse creates tolerance after a while. shortly after taking the drug, a person will not enjoy as the beginning of its use that is why the amount of substance used is gradually increased. the purpose of this study was to find the reas...

Background and Aims: Whole body vibration exercise by affecting the neuromuscular system and mechanical mechanisms increase muscles strength. This study investigated the effect of whole body vibration training on neuromuscular function of elderly men. Methods: Based on a randomized controlled trial design, 72 retired elderly men with a mean age of 73.00 ± 2.67 years participated in thisstudy. A...

background and purpose: self-medication is a global medical issue, the rate of which has been reported to be on the rise in recent years. this study aimed to evaluate the prevalence rate of self-medication and the associated factors among the university students of ahvaz city, iran. materials and methods: this cross-sectional study was conducted at jundishapur and shahid chamran universities of...

Whole-body vibration training is a method for muscle strengthening that is increasingly used in a variety of clinical situations. Key descriptors of vibration devices include the frequency, the amplitude, and the direction of the vibration movement. In a typical vibration session, the user stands on the device in a static position or performs dynamic movements. Most authors hypothesize that vib...

in this study, the mf285 tractor engine vibrations resulting from the use of different combinations of biodiesel, bioethanol and diesel as fuel were studied. engine vibrations in three directions and three engine speeds: 1000, 1600 rpm 2000 and ten fuel level was measured. to investigate the influence of measured parameters on engine vibration of factorial design in a randomized complete block ...

Performing exercise on a vibrating platform has gained popularity over the past decade among athletes. The potential therapeutic benefit of vibration also has been studied recently in clinical populations, although its clinical use began much earlier, in the 1940s, with the use of a special bed that delivered mechanical vibration to prevent bone loss in immobilized subjects (43). Further develo...

results: the most important diseases to consider in the differential diagnosis of fphl include chronic telogen effluvium (cte), permanent alopecia after chemotherapy (pac), alopecia areata incognito (aai) and frontal fibrosing alopecia (ffa). this review describes criteria for distinguishing these conditions from fphl. conclusions: the only approved treatment for fphl, which is 2% topical minox...

this paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. the cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. hamilton's principle is used to d...
