Name: Professor`s name: Course number: Date: Metabolic Pathways of Drugs The principal site for drug metabolism in the human body is the liver organ. The process of metabolism usually inactivates drugs though some drug metabolites are pharmacologically in active status. Inactive substance which has a metabolite that is active is referred to as a prodrug. Drugs are metabolized

Plastic Waste Management 1. Plastics Waste: Environmental Issues and Challenges The quantum of solid waste is ever increasing due to increase in population‚ developmental activities‚ changes in life style‚ and socio-economic conditions‚ Plastics waste is a significant portion of the total municipal solid waste (MSW). It is estimated that approximately 10 thousand tons per day (TPD) of plastics waste is generated i.e. 9% of 1.20 lacs TPD of MSW in the country. The plastics waste constitutes two major

simplest organic compounds and are a family of chain hydrocarbons having the general formula C2H2n+2. All of the bonds are single bonds (-C-H-‚ and -C-C-). The chains can be straight or branched. The smaller members (less than 4 carbons) are gases‚ while larger ones (five to seventeen carbons) are liquids. Beyond seventeen carbons the alkanes are waxy solids. Structure: The simplest saturated acyclic hydrocarbon is methane‚ CH4. The other hydrocarbons belonging to this class can be taken as descendents

converted to the orange sodium salt known as the methyl orange. INTRODUCTION Para-nitrobenzeneazoresorcinol dye and methyl orange belong to a class of dyes known as “azo colors” which contain the azo group linked to two aromatic nuclei. The nature of the aromatic substituent’s on both sides of the azo group (-N=N-) controls the colors of the azo compound as well as the water- solubility of dyes and how well they bind to a particular fabric. In addition to the azo group‚ the dyes

Absolutes‚ CO2s and Hydrosols are also commonly utilized in aromatherapy. Although essential oils‚ CO2 extracts and absolutes are distilled by different methods‚ the term essential oil is sometimes used as a blanket term to include all natural‚ aromatic‚ volatile‚ plant oils including CO2s and absolutes. In addition to essential oils‚ aromatherapy encourages the use of other complementary natural ingredients including cold pressed vegetable oils‚ jojoba (a liquid wax)‚ hydrosols‚ herbs‚ milk powders

crude oil. I have found out that they put crude oil into a machine and separate using an interesting method called fractional distillation. Fractional distillation of crude oil is where they separate out oil into hydrocarbons with similar boiling points‚ called fractions. Each hydrocarbon fraction contains molecules with similar numbers of carbon atoms. To my understanding I think each of these fractions boils at a different temperature range. That is because the different sizes of their molecules

reunification‚ however‚ it faced severe economic problems and was due to be closed down. The meeting between the scientists and DKK Scharfenstein resulted in the birth of ’Greenfreeze’ technology for domestic refrigeration. Greenfreeze refrigerators use hydrocarbons for both the blowing of the insulation foam and the refrigerant and they are entirely free of ozone destroying and global warming chemicals. When DKK Scharfenstein announced their intention to mass produce "Greenfreeze"‚ Greenpeace successfully
