Abstract. Natural gas (NG) must be treated to remove sulphur compounds and acid gases i.e., carbon dioxide (CO2) hydrogen sulfide (H2S) ensure that it complies with requirements for sale transportation. More than 95% of the NG processing plants are operated through removal unit (AGRU) using aqueous amine solvent in removing sour components from hydrocarbon due availability at a low cost. Howeve...

The therapeutic roles of phenolic blueberry (Vaccinium corymbosum) and blackberry (Rubus fruticosus) pomace (commercial byproduct) extracts (BPE) and their mechanism of actions were evaluated against methicillin resistant Staphylococcus aureus (MRSA). Five major phenolic acids of BPE, e.g., protocatechuic, p. coumaric, vanillic, caffeic, and gallic acids, as well as crude BPE completely inhibit...

AIMS To improve our understanding of the pharmacology of 'ecstasy' in recreational environments; in particular, to describe the composition of ecstasy pills, patterns of ecstasy use and the relationship between dose of 3,4-methylendioxymethamphetamine (MDMA) and resulting plasma concentrations. DESIGN, SETTING AND PARTICIPANTS A naturalistic observational study of 56 experienced 'ecstasy' use...

Consumption of illicit drugs is a new concern for water management that must be considered not only because of the social and public health aspects but also in an environmental context in relation with the contamination of surface waters. Indeed, sewage treatment plant (STP) effluents contain drug residues that have not been eliminated since STP treatments are not completely efficient in their ...

Differences between solution and solid state 13C nuclear magnetic resonance spectra of some amphetamines namely, 3,4-methylenedioxyamphetamine HCI, (R.S)-MDA HCI, the methyl derivative 3,4-methylenedioxy-N-methylamphetamine x HCI, (R,S)-MDMA x HCI, the ethyl derivative, (R,S)-MDEA x HCI, and the analogues (R,S)-methamphetamine HCI, (-)-ephedrine x HCI (the 3R,2S enantiomer as numbered here), an...

Hair analysis is a reliable tool for detecting long-term exposure to illegal drugs, including amphetaminetype stimulants, over periods from a few weeks to a few months, depending on the length of the hair used for analysis. Between 2000 and 2012, over 600 hair samples were analysed at the Institute for Medical Research and Occupational Health, Croatia (IMROH) for the presence of amphetamine-typ...

Aiming at the iron and steel industry decarbonisation with blast furnace gas (BFG) utilisation, a techno-economic feasibility of pre-combustion carbon capture methyl diethanolamine (MDEA) is evaluated herein. The effectiveness water shift (WGS) implementation on performance also investigated. integration power plant decarbonised fuel from unit taken into account both technical economic perspect...
