In this study, olive oil residue (OR) biomass was pyrolyzed in the presence of bulk MgO (B-MgO), nano-MgO (N-MgO), ZnO (B-ZnO)), and nano-ZnO (N- ZnO) metal oxides at different temperatures (400, 600, 800 ºC). Significant results were obtained terms synthesis gas formation CO2 reduction. The efficiency distribution products as a result oxide-based pyrolysis process effects examined detail. Nano...

The Gas Chromatograph Mass Spectrometer (GCMS) on the Huygens Probe will measure the chemical composition of Titan’s atmosphere from 170 km altitude (∼1 hPa) to the surface (∼1500 hPa) and determine the isotope ratios of the major gaseous constituents. The GCMS will also analyze gas samples from the Aerosol Collector Pyrolyser (ACP) and may be able to investigate the composition (including isot...

The essential oil from the aerial parts of Iranian and British Thymus vulgaris L. were obtained by hydro distillation and analyzed by gas chromatography (GC) and gas chromatographymass spectrometry (GC-MS). Forty two components were identified in the Iranian Th. vulgaris essential oil that represented 99.06% of the oils. The major components were thymol (60.54%), γTerpinene (9.47%), p-cymene (8...

Primary carnitine deficiency (PCD) is a rare autosomal recessive disorder, caused by deficiency in the plasma membrane carnitine transporter. In this report, we aimed to describe the diagnosis and treatment of 12 PCD patients. Blood spots were collected from the children, and analysed using liquid chromatography-mass spectrometry (LC-MS). Newborns and children who had repeated lower dried blood...

The aim of this study was to screen for microorganism that able to utilize 3-N-trimethylamino-1-propanol (homocholine) as a sole source of carbon and nitrogen. The aerobic degradation of homocholine has been found by a gram-positive Rhodococcus sp. bacterium isolated from soil. The isolate was identified as Rhodococcus sp. strain A4 based on the phenotypic features, physiologic and biochemical ...

Drcarboxylic aciduria is a condition sometimes encountered during routine urine screening for inborn errors of metabolism [l] and may be due to ketosrs, a transient condition m some neonates [2] or a number of enzyme deficiencies mainly involving fatty acid metabolism or transport. Unsaturated dicarboxylic acids have also been reported m some of these conditions. These compounds are usually det...
