methamphetamine hydrochloride is a white to light brown crystalline powder, or clear chunky crystals resembling ice. the majority of street methamphetamine is produced in clandestine laboratories. the drug manufacturer states that patients should be informed that methamphetamine and amphetamine may impair the ability to engage in potentially hazardous activities such as driving a motor vehicle....

This paper presents the optimal operation of a photovoltaic pumping system. The operation of a permanent magnet brushless DC motor driving a centrifugal pump is investigated. The motor is controlled through a hysteresis current loop and an outer speed loop with a PI type controller. The proportional and integral gains are set to their optimal values. In order to optimise the overall system effi...

Vehicular Ad hoc Network can ease our life by making driving safe in near future. To make it successful efficient routing protocols need to be used for communication among vehicles. This communication can be direct within vehicles and can be through road side units (RSUs). In this paper we are exploiting the AODV, DSR and DSDV routing protocols by comparing their performances with respect to th...

The paper analyzes the determinants of the efficiency levels reached by twenty-one African water utilities. Efficiency is assessed through the estimation of a production frontier for the sector in Africa. The efficiency estimates confirm much of the common perceptions from partial productivity indicators. They point to a great heterogeneity in the African water utilities’ performances, the pred...

The present study examined the associations driving under the influence of (a) cannabis and (b) alcohol, and motor vehicle collisions during, in a longitudinal study of a New Zealand birth cohort (n=936). Participants reported significantly (p<.0001) greater rates of driving under the influence of cannabis than driving under the influence of alcohol during ages 21-25. Also, there were statistic...

Ignition interlocks are effective in reducing recidivism among driving while intoxicated (DWI) offenders while installed on their vehicles. However, the devices are not widely used in the USA. This survey gauged public support for requiring ignition interlocks for all convicted DWI offenders including first-time offenders. 69% of respondents supported such a policy. Support was lowest (38%) amo...

epilepsy is a disease with high prevalence, which interferes driving and may lead to car accident this case-control study has been done on 100 epileptic patients and 100 persons as control group, who had history of driving. we gathered our patients with face to face interview and registering their information in special forms which were prepared for this study. there were three times more accid...

This study developed a scale to measure 502 Taiwan traffic police officers' perceived ability to detect, detain, and intercept those vehicles whose drivers are driving while intoxicated (DWI) when conducting sobriety checkpoints. Through factor analysis, the officers' enforcement ability was found to consist of two component latent traits: detecting ability (DA) and detaining and intercepting a...

The purpose of this study was to investigate the influence of exposure to others' drink driving during adolescence on self-reported driving under the influence (DUI) of alcohol in young adulthood. Data were drawn from 1956 participants with a driving license enrolled in the International Youth Development Study from Victoria, Australia. During 2003 and 2004, adolescents in Grades 7, 9 and 10 (a...

This paper presents a study of Magnetic Shape Memory Alloy (MSMA) performances oriented to the design of a hydraulic pump. Its main properties, high strain and force under small response time requirement, have been recently improved via acoustic assistance by means of piezoelectric actuation. This research encloses a novel study in MSMA actuation technology regarding force and power mechanical ...
