A gold coated copper rotating electrode was used to eliminate surface oxidation effect. This study examined the effect of electrode rotation on the ozone generation process and showed that an ozonizer with an electrode rotating system might be a possible way to increase ozone-synthesis efficiency. Two new phenomena appeared during experiments with the rotating electrode. First was that ozone co...

BACKGROUND Evidence is accumulating that a cannabis withdrawal syndrome is common, of clinical significance, and has a clear time course. Up till now, very limited data exist on the cannabis withdrawal symptoms in patients with co-morbid substance use disorders, other than cannabis use and tobacco use. METHODS Symptoms of withdrawal were assessed through patient self-reports during detoxifica...

In this study, the effect of reversible inactivation of locus ceruleus (LC) on naloxone- induced withdrawal syndrome in paragigantocellular (PGi) neurons in morphine- dependent rats was investigated. For inactivation of LC, 1 µl of lidocaine (2%) was used and for induction of withdrawal syndrome, naloxone hydrochloride (2 mg/kg) was injected systemically. The results showed that in dependent gr...

We demonstrate that the attractive magnetic force acting on a rotating magnetic device (e.g., a magnetic microrobot), actuated using a rotating magnet dipole, can be converted into a lateral force by rotating the actuator dipole according to a specific open-loop trajectory. Results show rotating magnetic devices can be rolled and simultaneously pushed along a surface by the lateral force, resul...

objective: addiction, especially morphine dependence is a prevalence and incurable disease. with regard to low ability of new chemical drugs in treatment of addicted ones and with respect to herbal medicine recommendation due to lower side effects and cheap production. this study experimentally examined the effect of p.harmala on morphine withdrawal syndrome. materials and methods: animals wer...

background: the study was performed to investigate the effects of morphine dependency and morphine withdrawal on the reproductive system of adult male rat(wistar).  methods: 32 adult male rat divided into 5 groups. animals in the control group (n=8) received normal saline (1ml/kg) twice daily subcutaneously for 30 consecutive days. animals in dependent group (n=8) received morphine (10mg/ml/kg)...

Smoking is a widespread health problem. Because the nicotine withdrawal syndrome is a major contributor to continued smoking and relapse, it is important to understand the molecular and behavioral mechanisms of nicotine withdrawal to generate more effective smoking cessation therapies. Studies suggest a role for calcium-dependent mechanisms, such as L-type calcium channels and calcium/calmoduli...

The back-bending phenomenon for compact stars is studied by means of analytical equations of state, for both constant-pressure phase transitions and the transitions through the mixed-phase region. We restrict ourselves to the case of normal rotating configurations, with baryon mass below the maximum allowable baryon mass for non-rotating stars. We use high-precision 2-D multi-domain spectral co...
