Biodiesel, el Combustible Vegetal

Vegetal Marijuana, Animal Marijuana

Marijuana is the illicit drug most commonly used worldwide. The mechanisms by which this drug affects the brain have been studied exhaustively during the last 40 years, and better understood in the last decade. For example, the discovery of receptors to which marijuana binds, has been a major achievement in neurosciences and in the study of drug addiction. Moreover, the description of the endog...

AKR1C1 as a Biomarker for Differentiating the Biological Effects of Combustible from Non-Combustible Tobacco Products

Smoking has been established as a major risk factor for developing oral squamous cell carcinoma (OSCC), but less attention has been paid to the effects of smokeless tobacco products. Our objective is to identify potential biomarkers to distinguish the biological effects of combustible tobacco products from those of non-combustible ones using oral cell lines. Normal human gingival epithelial cel...

Method for Determining the Concentration of Unknown Combustible Gas †

It is known that catalytic sensors have different sensitivities to different combustible gases. Usually gas analyzers are calibrated by methane and not suitable for measuring other flammable gases. Correction is needed to get real concentration of other gases. In this paper it is shown that sensor sensitivity to one particular gas alters with sensor temperature and each gas has its own rate of ...

Smoke, the chief killer--strategies for targeting combustible tobacco use.

are offset to a degree by revenue generated through fines. One barrier to successful implementation of Tobacco 21 laws is the prospect of incomplete compliance by retailers. Compliance with the 18-year minimum has been variable, and interventions to boost compliance have had mixed success.5 Some retailers may prove even more reluctant to comply with Tobacco 21 laws, particularly in challenging ...
