An unstructured growth model for the recombinant methylotrophic yeast P. pastoris Mut(+) expressing the heavy-chain fragment C of botulinum neurotoxin serotype A [BoNT/A(H(c))], was successfully established in quasi-steady state fed-batch fermentations with varying cell densities. The model describes the relationships between specific growth rate and methanol concentration, and the relationship...

epidemics of methanol poisoning happen across the globe. there are prognostic factors associated with morbidity or mortality from methanol poisoning. recently we have compared retrospective observational case series of methanol-poisoned patients from norway (1979 and 2002-2005), estonia (2001) and tunisia (2003/2004), and patients from two different centers in iran (teheran 2004-2009 and mashha...

introduction methanol is a highly toxic substance and methanol poisoning results in severe health situations. methanol poisoning occurs when it is consumed by various methods such as orally, by inhalation, and transdermally. transdermal poisoning is rarely seen and causes severe health complications. conclusions methanol poisoning presents to the emergency department in our country with many di...

CO2 sensing is important in many applications ranging from air-quality monitoring to food packaging. In this study, an amine-functionalized copolymer, poly(N-[3-(dimethylamino)propyl]-methacrylamide-co-2-N-morpholinoethyl methacrylate) (p(D-co-M)) synthesized, offering moderate basicity suitable for a wide detection range. Taking advantage of characteristic p(D-co-M), polymer used designing che...

INTRODUCTION In an effort to improve air quality and decrease dependence on petroleum, the federal government, industry, and other groups have encouraged development of alternative fuels such as methanol to substitute for gasoline or diesel fuel. Methanol is also a candidate to provide the hydrogen for fuel cells, which are being developed for a variety of power sources (including motor vehicle...

A novel microplasma device, for the first time, was constructed in a cavity Poly (dimethylsiloxane) (PDMS) chamber with two normal syringe needles serve as both the gas channels and the electrodes. This device employs argon plasma with direct current for molecular fragmentation and excitation. The microplasma is generated at atmospheric pressure in the PDMS chamber of 0.5 mL (5 × 10 × 10 mm(3))...

Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...

abstract background: herbal distillates have been used for many centuries as drinks, flavors, and herbal medicine in iran, especially in the city of urmia. recently, some studies claimed the presence of methanol in different types of herbal distillates. methanol is a highly toxic compound which can cause acute or chronic toxicity in humans. acute poisoning with methanol can cause different comp...

The use of alcohol blends in direct alcohol fuel cells may be a more environmentally friendly and less toxic alternative to the use of methanol alone in direct methanol fuel cells. This paper assesses the behaviour of a direct methanol fuel cell fed with aqueous methanol, aqueous ethanol and aqueous methanol/ethanol blends in a long term experimental study followed by modelling of polarization ...

Mycobacterium smegmatis cells produce [3H]methanol when incubated with [methyl-3H]methionine. The methanol is derived from S-adenosylmethionine rather than methyltetrahydrofolate. M. smegmatis cells carboxymethylate several proteins, and some of the methanol probably results from their demethylation, but most of the methanol may come from an unidentified component with a high gel mobility. Alth...
