1. The ability of N-ethyl (MDEA) and N-butyl (MDBA) analogues of 3,4-methylenedioxymethamphetamine (MDMA, 'Ecstasy') to induce acute behavioural changes and increases in body temperature, and to cause serotonergic neurotoxicity, was assessed in young adult male Wistar rats. The in vitro ability of MDMA analogues to evoke presynaptic monoamine release from crude rat forebrain synaptosomal prepar...

In recent years, many multimedia and image encryption techniques based on chaotic maps have been proposed. In this paper, we propose a novel multimedia data encryption technique called MDEA (Multimedia Data Encryption Algorithm). Proposed encryption scheme is based on two digital chaotic maps, which in turn are used to generate two different chaotic sequences. Detail description of the proposed...

Validation of a Liquid Chromatography Tandem Mass Spectrometry Method for Targeted Degradation Compounds of Ethanolamine Used in CO2 Capture: Application to Real Samples — In the field of greenhouse gas emission, a promising approach consists in CO2 storage and capture. However most of the processes are based on amine solutions which are likely to Oil & Gas Science and Technology – Rev. IFP Ene...

first described by Gusserow in 1870 as a well differentiated adenocarcinoma in which most of the glands are impossible to be distinguished from the normal endocervical mucosa, although the MDA invades deep into the cervical stroma. At first, MDA was restricted to the mucinous type, but the definition of MDA has been expanded to other cell types, including the endometrioid, clear cell and nonspe...

Gas sweetening, the removal of acid gases (H2S and CO2) by absorption in aqueous alkanolamine solutions, is an important gas treatment operation. Methyldiethanolamine (MDEA) is widely employed for gas sweetening, because of its high absorption capacity and flexibility to meet process requirements. For process simulation or design, realistic predictions of acid gas solubilities in MDEA solutions...

Integrated CO2 capture and hydrogenation to produce formate offers a sustainable approach for reducing carbon dioxide emissions producing liquid hydrogen carriers (formate) simultaneously. In the current study, three different types of aqueous amine solutions including monoethanolamine (MEA), diethanolamine (DEA) triethanolamine (TEA) were investigated as CO2-capturing agents in presence Pd/NAC...

This study investigates the comparative impact of inherently different biomass and coal ashes on laboratory pilot scale degradation 30 wt% aqueous monoethanolamine (MEA), relevant to post-combustion CO2 capture. Thermal oxidative experiments were carried out at 135 °C 40 respectively with loading (0.5 molCO2/molMEA), without presence ash. Nuclear magnetic resonance (NMR) data is provided for ma...

The article presents research on the purification process of pyrolysis gas from hydrogen sulphide and CO2 which release waste tyre process. Pyrolysis, a for treating tyres to create priceless oil, coal, products, is gaining popularity, though. Chemically speaking, oil quite complex contains polar fractions as well almon, aromatic, heteroatoms. fuel properties reveal that it similar or light bur...
