introduction lentil (lens culinaris medik.) is a good source of protein, carbohydrates as well as minerals, vitamins and unsaturated fatty acids as such it plays an important role in the human diet and cultivated worldwide. water shortage is one of the most important abiotic factors that can limit morphological, physiological, yield, and plant distribution. legumes such as lentil are highly sen...

Methanol is a versatile compound that can be biologically synthesized from methane (CH4) by methanotrophs using a low energy-consuming and environment-friendly process. Methylocella tundrae is a type II methanotroph that can utilize CH4 as a carbon and energy source. Methanol is produced in the first step of the metabolic pathway of methanotrophs and is further oxidized into formaldehyde. Sever...

Methanol is responsible for a life-threatening poisoning. Fomepizole, a potent alcohol dehydrogenase inhibitor, is an efficient and safe antidote that prevents or reduces toxic methanol metabolism. Although no study has compared its efficacy with ethanol, fomepizole is recommended as a first-line antidote. Treatment should be started as soon as possible, based on history and initial findings in...

Pt-Pd catalyst supported on nitrogen-doped carbon nanofiber (N-CNF) was prepared and evaluated as a cathode electrode of the direct methanol fuel cell (DMFC). The N-CNF, which was directly synthesized by the catalytic chemical vapor deposition from acetonitrile at 640 °C, was verified as having a change of electrochemical surface properties such as oxygen reduction reaction (ORR) activities and...

Anti-amoebic effects of crude root extracts of Senna didymobotrya against Entamoeba histolytica infecting caecum of mice were studied. Caecal amoebiasis was induced by injection of Entamoeba histolytica trophozoites directly into the caecum. Mice were treated orally with the root dichloromethane extracts, ethyl acetate extracts, methanol total extracts, methanol successive extracts, hexane extr...

In our study, two-stage anaerobic system was employed to treat high concentration methanol wastewater. The results showed the COD removal efficiency was over 90% at the volume loading of 26.8kgCOD/(m.d) and two-stage anaerobic digestion of methanol wastewater was more efficient and stabler than one stage. The pH of the two UASBs was always lower than 6.0, which wasn’t the suitable condition tha...

using surface analysis, simultaneous effects of temperature (260-380ºc) and ethanol concentration (0-1%) on dimethyl ether (dme) selectivity, yields of hydrocarbon and dme, and methanol conversion were investigated in methanol dehydration reaction over γ-al2o3 catalyst. methanol conversion and yield of hydrocarbon/dme were found to be significantly affected by temperature and the temperature-et...

The explanation of the dielectric dynamics in methanol would offer knowledge of the Debye relaxation in supercooled monoalcohols. However, due to the fast crystallization, it is hard to attain the dynamics of pure methanol in the deeply supercooled region. In this paper, we studied the dynamics of methanol – 2-ethyl-1-hexanol mixtures with methanol concentration up to 80 mol% using dielectric a...

 Background and purpose: Medicinal plants are among highly consumed natural drugs. Many herb shops produce and sell this products without any license. Traditional herbal distillates are widely used in Iran, so, the aim of this study was to determine ethanol and methanol concentrations in handmade herbal distillates in Tehran herb shops. Materials and methods: A total of 140 samples from 14 tra...
