in order to evaluate the effects of foliar application of methanol and irrigation intervals on yield and yield components of chickpea cultivars a factorial experiment as split plots based on randomized complete block design with three replications was conducted in spring 2008 at the agricultural research station of ferdowsi university of mashhad. the treatments were 10 and 20 irrigation interva...
therapeutic effects of high dose intravenous prednisolone on methanol induced toxic optic neuropathy
background: the effects of high dose steroids for the treatment of methanol optic neuropathy was evaluated in this study. methods: in an interventional case series, 9 patients with a history of sudden visual loss after an ingestion of homemade alcoholic beverages were included in the study. the patients received 250 mg intravenous methyl prednisolone every 6 hours for 4 days continued with oral...
background: hospital surge capacity (hsc) is essential to the successful management of expected consequences of disasters and mass casualty incidents (mcis). in mcis, an unanticipated number of sick or injured people refer to the hospital, and thus, the hospital is faced with a significant increase in the burden of necessary activities and services. therefore, managing the process in order to m...
background: methanol is a colorless and poisonous liquid that is commonly used as an industrial and household solvent. methanol poisoning is a rare but extremely hazardous form of in toxication that affects the central nervous system and causes visual disorder, drowsiness, seizures and coma. case presentation: a 29-years-old man with methanol intoxication presented with drowsiness and acidosis...
Methanol is increasingly becoming an attractive substrate for production of different metabolites, such as commodity chemicals, and biofuels via biological conversion, due to the increment of annual production capacity and decrement of prices. In recent years, genetic engineering towards native menthol utilizing organisms – methylotrophy has developed rapidly and attracted widespread attention....
Treatment of thiacalix[8]arene (3.8H) with KH in THF, followed by recrystallization from methanol, affords an adduct of [K4(3.4H)].8MeOH as a pale yellow crystal (4), which shows highly-extensive coordination that gives rise to a zeolitic structure. An adduct of 4 gives apohost [K4(3.4H)] with the loss of methanol, which can adsorb such gaseous organic guest molecules as methanol and benzene. A...
Methanol has been promoted as an alternative transportation fuel from time to time over the past forty years. In spite of significant efforts to realize the vision of methanol as a practical transportation fuel in the US, such as the California methanol fueling corridor of the 1990s, it did not succeed on a large scale. This white paper covers all important aspects of methanol as a transportati...
In a previous study, the authors showed that iron(III) [tetrakis(pentafluorophenyl)]porphyrin chloride [(F20TPP)FeCl] is catalytically inactive for cyclooctene epoxidation by hydrogen peroxide in acetonitrile but is catalytically active if the solvent contains methanol. It was suggested that the precursor to the active species is (F20TPP)Fe(OCH3) in methanol-containing solvents. The present stu...
Optimal routing is an important part of the methanol road transportation research. Optimal routing of methanol is different from those general optimal routing processes. Methanol optimal routing need to take into account the risk of path, the possible consequences of the accident and emergency response capabilities around the path and other factors This paper includes two aspects of research, o...
“Candidatus Methylomirabilis oxyfera” is a newly discovered anaerobic methanotroph that, surprisingly, oxidizes methane through an aerobic methane oxidation pathway. The second step in this aerobic pathway is the oxidation of methanol. In Gramnegative bacteria, the reaction is catalyzed by pyrroloquinoline quinone (PQQ)-dependent methanol dehydrogenase (MDH). The genome of “Ca. Methylomirabilis...
