Amyloid beta peptides do not form peptide-derived free radicals spontaneously, but can enhance metal-catalyzed oxidation of hydroxylamines to nitroxides. (1/92)

Amyloid beta (Abeta) peptides play an important role in the pathogenesis of Alzheimer's disease. Free radical generation by Abeta peptides was suggested to be a key mechanism of their neurotoxicity. Reports that neurotoxic free radicals derived from Abeta-(1-40) and Abeta-(25-35) peptides react with the spin trap N-tert-butyl-alpha-phenylnitrone (PBN) to form a PBN/.Abeta peptide radical adduct with a specific triplet ESR signal assert that the peptide itself was the source of free radicals. We now report that three Abeta peptides, Abeta-(1-40), Abeta-(25-35), and Abeta-(40-1), do not yield radical adducts with PBN from the Oklahoma Medical Research Foundation (OMRF). In contrast to OMRF PBN, incubation of Sigma PBN in phosphate buffer without Abeta peptides produced a three-line ESR spectrum. It was shown that this nitroxide is di-tert-butylnitroxide and is formed in the Sigma PBN solution as a result of transition metal-catalyzed auto-oxidation of the respective hydroxylamine present as an impurity in the Sigma PBN. Under some conditions, incubation of PBN from Sigma with Abeta-(1-40) or Abeta-(25-35) can stimulate the formation of di-tert-butylnitroxide. It was shown that Abeta peptides enhanced oxidation of cyclic hydroxylamine 1-hydroxy-4-oxo-2,2,6, 6-tetramethylpiperidine (TEMPONE-H), which was strongly inhibited by the treatment of phosphate buffer with Chelex-100. It was shown that ferric and cupric ions are effective oxidants of TEMPONE-H. The data obtained allow us to conclude that under some conditions toxic Abeta peptides Abeta-(1-40) and Abeta-(25-35) enhance metal-catalyzed oxidation of hydroxylamine derivatives, but do not spontaneously form peptide-derived free radicals.  (+info)

Butane metabolism by butane-grown 'Pseudomonas butanovora'. (2/92)

The pathway of butane metabolism by butane-grown 'Pseudomonas butanovora' was determined to be butane --> 1-butanol --> butyraldehyde butyrate. Butane was initially oxidized at the terminal carbon to produce 1-butanol. Up to 90% of the butane consumed was accounted for as 1-butanol when cells were incubated in the presence of 5 mM 1-propanol (to block subsequent metabolism of 1-butanol). No production of the subterminal oxidation product, 2-butanol, was detected, even in the presence of 5 mM 2-pentanol (an effective inhibitor of 2-butanol consumption). Ethane, propane and pentane, but not methane, were also oxidized. Butane-grown cells consumed 1-butanol and other terminal alcohols. Secondary alcohols, including 2-butanol, were oxidized to the corresponding ketones. Butyraldehyde was further oxidized to butyrate as demonstrated by blocking butyrate metabolism with 1 mM sodium valerate. Butyrate also accumulated from butane when cells were incubated with 1 mM sodium valerate. The pathway intermediates (butane, 1-butanol, butyraldehyde and butyrate) and 2-butanol stimulated O2 consumption by butane-grown cells. 1-Butanol, butyraldehyde and butyrate supported growth of 'P. butanovora', as did 2-butanol and lactate.  (+info)

Flow cytometric measurement of micronuclei induced in a permanent fish cell line as a possible screening test for the genotoxicity of industrial waste waters. (3/92)

An in vitro micronucleus assay using the permanent fish cell line RTG-2 (rainbow trout gonads) was developed to test industrial waste waters for their genotoxic potential. Comparison of flow cytometric measurement and microscopic scoring of micronucleus frequency with the reference chemicals 1,4-butane sultone (0.2-1 mM), ethylmethane sulphonate (2-10 mM), potassium dichromate (20-100 microM) and benzo[a]pyrene (5-25 microM) showed similar dose-effect relationships. Thirty-eight industrial waste waters from 11 different branches of industry obtained from the Bavarian state office for water research were tested using the flow cytometric method (18 from metal processing, 10 from combined waste water, two from synthetic fibre production, one sample each from settlement wastes, non-iron metal manufacturing, leather production, sulphuric acid production, ore processing, graphite film production, cellulose production and flue gas washing). Fourteen of them showed a significant increase in micronucleus frequency.  (+info)

The effects of electron and chemical ionization modes on the MS profiling of whole bacteria. (4/92)

Free fatty acid profiling of whole bacteria [Francisella tularensis, Brucella melitensis, Yersinia pestis, Bacillus anthracis (vegetative and sporulated), and Bacillus cereus] was carried out with direct probe mass spectrometry under 70-eV electron ionization (EI) and isobutane chemical ionization in both the positive (CI+) and negative modes (CI-). Electron ionization produced spectra that contained molecular ions and fragment ions from various free fatty acids. Spectra acquired with isobutane chemical ionization in the positive mode yielded molecular ions of free fatty acids as well as ions from other bacterial compounds not observed under EI conditions. Spectra obtained with negative chemical ionization did not contain as much taxonomic information as EI or CI+; however, some taxonomically significant compounds such as dipicolinic acid and poly(3-hydroxybutyrate) did produce negative ions. All ionization modes yielded spectra that could separate the bacteria by Gram-type when observed with principle components analysis (PCA). Chemical ionization in the positive ion mode produced the greatest amount of differentiation between the four genera of bacteria when the spectra where examined by PCA.  (+info)

Diversity in butane monooxygenases among butane-grown bacteria. (5/92)

Butane monooxygenases of butane-grown Pseudomonas butanovora, Mycobacterium vaccae JOB5, and an environmental isolate, CF8, were compared at the physiological level. The presence of butane monooxygenases in these bacteria was indicated by the following results. (i) O(2) was required for butane degradation. (ii) 1-Butanol was produced during butane degradation. (iii) Acetylene inhibited both butane oxidation and 1-butanol production. The responses to the known monooxygenase inactivator, ethylene, and inhibitor, allyl thiourea (ATU), discriminated butane degradation among the three bacteria. Ethylene irreversibly inactivated butane oxidation by P. butanovora but not by M. vaccae or CF8. In contrast, butane oxidation by only CF8 was strongly inhibited by ATU. In all three strains of butane-grown bacteria, specific polypeptides were labeled in the presence of [(14)C]acetylene. The [(14)C]acetylene labeling patterns were different among the three bacteria. Exposure of lactate-grown CF8 and P. butanovora and glucose-grown M. vaccae to butane induced butane oxidation activity as well as the specific acetylene-binding polypeptides. Ammonia was oxidized by all three bacteria. P. butanovora oxidized ammonia to hydroxylamine, while CF8 and M. vaccae produced nitrite. All three bacteria oxidized ethylene to ethylene oxide. Methane oxidation was not detected by any of the bacteria. The results indicate the presence of three distinct butane monooxygenases in butane-grown P. butanovora, M. vaccae, and CF8.  (+info)

Detection of different types of damage in alkylated DNA by means of human corrective endonuclease (correndonuclease). (6/92)

Corrective endonuclease (correndunclease) activity of HeLa cells was assayed with alkylated DNA. Double-stranded, covalently closed DNA from phage PM II was treated with methyl methanesulfonate, N-methyl-N-nitrosourea, beta-propiolactone, or diepoxybutane to introduce alkylated bases and alkali-labile sites into the DNA. The damaged DNA was incubated with an extract of HeLa cells that catalyzes the formation of breaks at apurinic sites in double-stranded DNA. Methylated DNA was broken at every alkali-labile site by the HeLa correndonuclease, which indicated that these sites are similar to the apurinic sites produced by heating at acid pH. DNA alkylated with beta-propiolactone or diepoxybutane containing the same number of alkali-labile sites was broken to a far lesser extent. This indicates the presence of a second type of alkali-labile damage that is correndonuclease-insensitive.  (+info)

Successful resuscitation from recurrent ventricular fibrillation secondary to butane inhalation. (7/92)

Resuscitation from cardiac arrest caused by volatile substance abuse is rarely successful. Large doses of catecholamines given during resuscitation, in the presence of butane, may cause recurrent ventricular fibrillation. We report a case of prolonged resuscitation in a young man who had inhaled butane. Cardiac output was restored 10 min after the administration of intravenous amiodarone. We suggest that antiarrhythmic agents should be used early during resuscitation to prevent recurrent arrhythmias.  (+info)

An inducible 1-butanol dehydrogenase, a quinohaemoprotein, is involved in the oxidation of butane by "Pseudomonas butanovora". (8/92)

Butane-grown "Pseudomonas butanovora" expressed two soluble alcohol dehydrogenases (ADHs), an NAD(+)-dependent secondary ADH and an NAD(+)-independent primary ADH. Two additional NAD(+)-dependent secondary ADHs could be detected when cells were grown on 2-butanol and lactate. The inducible NAD(+)-independent 1-butanol dehydrogenase (BDH) of butane-grown cells was primarily responsible for 1-butanol oxidation in the butane metabolism pathway. BDH was purified to near homogeneity and identified as a quinohaemoprotein, containing, per mol enzyme, 1.0 mol pyrroloquinoline quinone (PQQ) and 0.25 mol haem c as prosthetic groups. BDH was synthesized as a monomer of approximately 66 kDa. It has a broad substrate range, including primary alcohols, secondary alcohols, aldehydes, C(4) diols and aromatic alcohols. It exhibited the lowest K:(m) (7+/-1 microM) and highest k(cat)/K:(m) (72x10(4) M(-1) s(-1)) value towards 1-butanol. BDH exhibited ferricyanide-dependent ADH activity. Calcium ions (up to 10 mM) increased BDH activity substantially. Two BDH internal amino acid sequences showed 73 and 62% identity and 83 and 66% similarity, respectively, when compared with an amino acid sequence of ethanol dehydrogenase from Comamonas testosteroni. The presence of the inducible BDH and secondary ADH may indicate that the terminal and subterminal oxidation pathways are involved in butane degradation of butane-grown "P. butanovora".  (+info)

Butane is one of dozens of gases extracted from raw natural gas and can also be produced from crude oil. Butane is also able to liquefy quickly when it is compressed. Butane can be called n-butane (the n in front of butane stands for normal); n-butane is a multipurpose colorless gas. For instance butane can be used for heating, refrigeration, and fuel for lighters. Butane is often mixed with propane to create LPG (liquefied petroleum gas) which is also used for cooking heating and other commercial purposes. Butane can also burn to form carbon dioxide and water vapour when oxygen is plentiful; however when there is a lack of oxygen carbon (soot) or carbon monoxide can also be formed ...

Introduction. MOLAR MASS OF BUTANE Name: Ingrid Foss Ballo Class: 2IBJ Team: Ingrid Foss Ballo and Maike Jule Sonnewald Petersen Date: Tuesday 30th of January, 2004 AIMS The purpose of this activity is to determine the molar mass of butane using gas from a butane lighter. The experiment depends on the fact that the molar volume of an ideal gas is 22,4L at standard temperature and pressure (0 ?C and 101,3 kPa). By measuring the volume occupied by a known mass of butane, and knowing that its molar volume is 22,4L at S.T.P., it is possible to calculate the molar mass of butane. METHODS AND TOOLS Equipment - Piece of glass tubing - approximately 24 cm long and with a diameter of approximately 25 mm, closed at one end (with markings for mL). - Container for water - Butane lighter - Restort stand, boss head and clamp - Thermometer (-10-100 ?C) Procedure We filled both the glass tubing and the container with water. Then we inverted the tubing and place the open end of it under the surface of the water ...

Aim: To find the molar mass of butane, by finding the number of moles of gas in the container and comparing it to the mass of butane in the container. Theory. Butane (C4H10), also called n-butane, is the unbranched alkane with four carbon atoms, CH3CH2CH2CH3. Its only other isomer is methylpropane: CH(CH3)3. It is an organic compound which belongs to the alkane group or organic compounds. It is a highly flammable, colourless and odorless gas at r.t.p. this, along with the fact that is an easily liquedified gas, is why it is used in lighters as a fuel. Its Relative Molecular Mass is 58.12g, and it is barely soluble in water like most organic compounds: 0.0061 g/100 cm3, at 20 �C.. In the experiment we shall find the mass of butane by calculating the change in mass of the lighter before and after the experiment. We shall find the number of moles in the container by finding the volume, pressure and temperature of butane inside the container, and then use the formula PV = nRT (where P: Absolute ...

BHO is more harmful than the plant it comes from, and its rise in popularity means that more and more incidents are occurring.. Butane: The process of boiling off the butane is not 100 percent effective, meaning that traces of it exist in the resulting oil. Users then inhale this butane, which can impair the brain and nervous system, causing an increased heart rate, dizziness and loss of consciousness. Poorly manufactured batches can contain larger amounts of BHO, causing more damage. Inhaling too much butane can be lethal.. THC content: Because BHO is so pure, the amount of THC it contains makes it powerfully psychoactive. Although not life-threatening, a very large dose of BHO can lead to vomiting in addition to anxiety, paranoia and other psychological issues that can persist for days.. Manufacturing process: The most dangerous aspect of BHO is the manufacturing process. Butane is extremely volatile, and large amounts of it are used in mostly closed-room makeshift labs. Often those making BHO ...

TAGUIG CITY: Due to a number of reported incidents, the Department of Energy (DOE) warns the general public on the dangers of using LPG-refilled butane canisters for household consumption.. Butane canisters are used only on a one time basis and must never be refilled with LPG, which has a higher pressure than butane, and thus may cause accidents (i.e., explosion, fire, etc.) while in use.. The DOE emphasized that these butane canisters are not intended and designed to be refilled, more so with LPG. Based on existing Philippine National Standards for gas containers, only welded steel cylinders are designed for storage, transport and distribution of LPG for domestic consumption.. The DOE would also like to reiterate Department Circular DC2014-01-0001 which outlines the rules and regulations governing the Liquefied Petroleum Gas (LPG) Industry, especially the sets of standards for compliance of all LPG Industry participants (i.e., refiners, importers, refillers, marketers, and even haulers). ...

In this study, Cr and Co promoted, as well as unpromoted vanadium phosphate (VPO) catalysts were synthesized by the reaction of V2O5 and o-H3PO4 in organic medium followed by calcination in n-butane/air environment at 673 K. The physico-chemical properties and the catalytic behavior were affected by the addition of Cr and Co dopants. H2-TPR was used to investigate the nature of oxidants in the unpromoted and promoted catalysts. The results showed that both the Cr and Co promoters remarkably lowered the temperature of the reduction peak associated with V5+. The amount of oxygen species originated from the active phase, V4+, removed was significantly increased for Co and Cr-promoted catalysts. Both Cr and Co dopants improve strongly the n-butane conversion without sacrificing the MA selectivity. A good correlation was observed between the amount of oxygen species removed from V4+ phase and the activity for n-butane oxidation to maleic anhydride. This suggested that V4+-O was the center for the ...
We investigated the efficacy of fuel stratification in a pre-mixture of di-methyl ether (DME) and n-Butane, which have different auto-ignition characteristics, for reducing the pressure rise rate (PRR) of homogeneous charge compression ignition (HCCI) engines. A new chemical reaction model was created by mixing DME and n-Butane and compared to existing chemical reaction models to verify the effects. The rate of maximum pressure rise depends on mixture ratio. When DME was charged with stratification and n-butane was charged with homogeneity, the maximum PRR was the lowest. The calculations were performed using the SENKIN application of CHEMKIN-II.. Copyright © 2011 by KSME ...
Performance of Ni/Al2O3 catalysts (10 wt.% Ni) in steam reforming of n-butane was investigated in terms of n-butane conversion, selectivity to hydrogen and hydrogen yield. The process was carried out in a fixed-bed tubular reactor at 650 °C and atmospheric pressure. The volumetric flow rates of n-butane and steam were 0.1 mL/min and 0.6 mL/min, respectively. The catalysts were prepared by precipitation-sedimentation method at different precipitation, drying and calcination temperatures as well as precursor types. Synthesized catalysts were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and BET analyses. It was found that Ni- Nitrate as the precursor was more favorable than the other. Mathematical predictive formulas were generated for responses by Design Expert software. Also, the optimum condition of the catalyst preparation was obtained by using the response surface methodology (RSM). Ultimately, it was concluded that the overall optimum condition were: Tprecipitation=

The anaerobic formation and oxidation of methane involve unique enzymatic mechanisms and cofactors, all of which are believed to be specific for C1-compounds. Here we show that an anaerobic thermophilic enrichment culture composed of dense consortia of archaea and bacteria apparently uses partly similar pathways to oxidize the C4 hydrocarbon butane. The archaea, proposed genus Candidatus Syntrophoarchaeum, show the characteristic autofluorescence of methanogens, and contain highly expressed genes encoding enzymes similar to methyl-coenzyme M reductase. We detect butyl-coenzyme M, indicating archaeal butane activation analogous to the first step in anaerobic methane oxidation. In addition, Ca . Syntrophoarchaeum expresses the genes encoding β-oxidation enzymes, carbon monoxide dehydrogenase and reversible C1 methanogenesis enzymes. This allows for the complete oxidation of butane. Reducing equivalents are seemingly channelled to HotSeep-1, a thermophilic sulfate-reducing partner bacterium ...

Butane has pretty high boiling point (around $\ce{0 °C}$). This means, that just cooling air to $\ce{-30 °C}$ should condense a lot (if not all) of butane from it.. However, as I guess, most of butane used in foam production remains in the foam, otherwise the foam would collapse. So, it is very possible that there is not much to recycle in air itself. The gas, of course, will be released eventually, but only when foam itself is destroyed. ...

Isobutane is converted to methacrolein in an integrated two-step process wherein isobutane is dehydrogenated in a first step to isobutylene, hydrogen, and by-products and the reaction effluent is passed directly into a second step where isobutylene is oxidized to methacrolein without significant oxidation of the hydrogen and by-products. The methacrolein and by-products may be separated and the unreacted isobutylene and isobutane recycled to the first step. Alternatively, the effluent from the second step may be used as feed to a further oxidation step for conversion of methacrolein to methacrylic acid. In one embodiment, the hydrogen produced in the first step is oxidized using the excess oxygen from the second step under conditions selected to avoid loss of the C 4 components. In an alternative embodiment, the unreacted isobutane and isobutylene are absorbed and separated from the remaining components before being recycled to the first step.
In this study, the dehydrogenation component of Ga2O3 was introduced into ZSM-5 nanocrystals to prepare Ga2O3/ZSM-5 hollow fiber-based bifunctional catalysts. The physicochemical features of as-prepared catalysts were characterized by means of XRD, BET, SEM, STEM, NH3-TPD, etc., and their performances for the catalytic conversion of n-butane to produce light olefins and aromatics were investigated. The results indicated that a very small amount of gallium can cause a marked enhancement in the catalytic activity of ZSM-5 because of the synergistic effect of the dehydrogenation and aromatization properties of Ga2O3 and the cracking function of ZSM-5. Compared with Ga2O3/ZSM-5 nanoparticles, the unique hierarchical macro-meso-microporosity of the as-prepared hollow fibers can effectively enlarge the bifunctionality by enhancing the accessibility of active sites and the diffusion. Consequently, Ga2O3/ZSM-5 hollow fibers show excellent catalytic conversion of n-butane, with the highest yield of light olefins

Most of what consumers know as marijuana concentrate, dabs, wax, or BHO is made with a butane extraction system. Butane is an inexpensive solvent, so its the most common one used by amateur extractors. Though BHO can be safely made in closed-loop systems-where the butane gas is trapped, recycled and reused in a controlled, sealed environment-its sometimes processed in a much cheaper open blast system thats highly explosive, and extremely dangerous for non-professionals.. In the past, extracting of any kind was a great way to monetize a moldy crop or leftover trim that might otherwise be useless; but we now realize that most extraction methods are actually garbage in, garbage out, and the quality of nugs or sweet leaf used in the extraction ends up reflected in the quality of the concentrate-leading to a huge variety in the quality of BHO on the market. BHO varies greatly in color and texture, from yellow shatter to dark-green wax.. This happens because butane doesnt discriminate ...
Isobutane is used as a refrigerant.[10] The use in refrigerators started in 1993 when Greenpeace presented the Greenfreeze project with the German company Foron.[11] In this regard, blends of pure, dry isobutane (R-600a) (that is, isobutane mixtures) have negligible ozone depletion potential and very low global warming potential (having a value of 3.3 times the GWP of carbon dioxide) and can serve as a functional replacement for R-12, R-22, R-134a, and other chlorofluorocarbon or hydrofluorocarbon refrigerants in conventional stationary refrigeration and air conditioning systems. As a refrigerant, isobutane poses an explosion risk in addition to the hazards associated with non-flammable CFC refrigerants. Substitution of this refrigerant for motor vehicle air conditioning systems not originally designed for isobutane is widely prohibited or discouraged.[12][13][14][15][16][17][18] Vendors and advocates of hydrocarbon refrigerants argue against such bans on the grounds that there have been very ...

Dear Hugh,. In response to D.H.s questions on gas, I offer my thoughts. Generally, I would tell anyone to use the gas specifically recommended for the equipment they intend to use. Trying to keep it simple about the different gases, an explanation of the differences follows.. The first difference between the gases is chemical makeup. Propane has three carbons atoms (and hydrogen atoms) in the molecule. Butane has four carbons, and so does its isomer iso-butane. Butane is arranged in a four carbon chain, while Iso-butane has a center carbon, with the other three carbons coming off like spokes, and they have different flash points. Natural gas is a combination of methane (one carbon) and many of these other gases. Propane, methane, and butane are all derived from natural gas through a process called fractional distillation that takes advantage of each chemicals flash points to separate them and remove impurities. Natural gas is brought up from the earth in different ways, but it gets purified ...

The atmosphere of Titan, one of Saturns moons, is of great interest to the scientific community. With its primary components of nitrogen and methane, many believe Titan to be an analog of prebiotic Earth. The Cassini-Hyugens mission, launched in 1997, gathered massive amounts of data from both Saturn and Titan that is still being interpreted. Analysis of astronomical spectra is dependent on high-quality laboratory spectra. In the case of Titan this includes small hydrocarbons such as ethane, propane and benzene that are the products of photochemistry of methane. One complication that arises when making these assignments comes from incomplete or absent line-by-line spectroscopic data commonly used to determine molecular abundances. This problem can be avoided by utilizing absorption cross sections, as they are only dependent on the environment of the target molecule, environments that can be replicated in the lab. One of the molecules that potentially exists on Titan is isobutane. This talk ...
In chemistry, an open-chain compound (also spelled as open chain compound) or acyclic compound (Greek prefix α, without and κύκλος, cycle) is a compound with a linear structure, rather than a cyclic one. An open-chain compound having no side chains is called a straight-chain compound (also spelled as straight chain compound). Many of the simple molecules of organic chemistry, such as the alkanes and alkenes, have both linear and ring isomers, that is, both acyclic and cyclic, with the latter often classified as aromatic. For those with 4 or more carbons, the linear forms can have straight-chain or branched-chain isomers. The lowercase prefix n- denotes the straight-chain isomer; for example, n-butane is straight-chain butane, whereas i-butane is isobutane. Cycloalkanes are isomers of alkenes, not of alkanes, because the rings closure involves a C=C bond. Having no rings (aromatic or otherwise), all open-chain compounds are aliphatic. Typically in biochemistry, some isomers are more ...

This research was conducted by the Cultural and Indigenous Research Centre Australia (CIRCA) on behalf of the Department of Families, Housing, Community Services and Indigenous Affairs (FaHCSIA). The aim of the research was to inform future communication strategies and policy designed to reduce the incidence of substance use among Aboriginal young people in the East Kimberly and Central Desert Regions. Researchers conducted stakeholder interviews in the Northern Territory (NT) and Western Australia (WA), including site visits to Docker River (NT) and Kununurra (WA) between September and October 2009.. One of the major findings of this research is that communications are not seen as a priority for addressing Volatile Substance Abuse (VSA) among Aboriginal young people. Instead of funding communications, providing significant funding and support for Youth diversion programs was identified as a way to have the greatest impact on VSA.. The research identified that the most likely way to use ...
Inhalant abuse is a problem that is getting more common all around the world. The increase in prevalence of inhalant abuse escalates morbidity and mortality rates. About 22% of people using inhalant have died at their first attempt. Particularly propane, butane, or propane-butane mixture has highest mortality rates. Sudden sniffing death syndrome, cardiomyopathy, central nervous system toxicity, hematological abnormalities, kidney toxicity, and hepatocellular toxicities are the major complications of inhalant abuse. Herein we present a patient with inhalant use disorder. At the age of 19, after a stressful life event he had unsuccessfully tried to suicide by inhaling LPG (liquefied petroleum gas, a mixture of butane and propane gases). After he realized that he had hallucinations and felt better during the inhalation, he started to abuse it. He was addicted to LPG for 10 years at the time of admission. Besides being dangerous for the society security, this intense level of LPG inhalation (12

What are the basic questions addressed? How are macroscopic properties such as the self diffusion coefficient, viscosity and thermal conductivity related to microscopic processes occurring in non-equilibrium alkane liquids? What are the results to date and future of the work? The thermal conductivity tensor of shearing liquid butane has been studied by non-equilibrium molecular dynamics methods. We have found that the effect of shear on the thermal conductivity tensor is calculable by our methods, but it is too small to be measured experimentally at the accessible strain rates. The effect is known to be measurable for polymer melts, but simulation of such systems will be difficult due to the huge computer power required. We have completed a study in which the linear thermal conductivity of liquid butane has been calculated by non-equilibrium methods using two different molecular models. The first model was the Ryckaert-Bellemans model, a well known united atom model, and the second was a more ...

But as long as I do the right thing maybe canisters arent so bad after all? If only it were that simple! I guess we have got used to most camping gear being made in Asia, but did you know that despite the boom in oil and gas production in North America your stove fuel is coming all that way too? Actually the gas in the canister comes even further but the canister is made and filled in South Korea, and all by the same company. This makes those warnings to use only brand X gas in your stove even funnier when you realise that the same production line is spitting out the same canisters and just painting them a different colour. If you take an interest in world affairs you may have already spotted another problem with this arrangement. South Korea has no oil or gas of its own. Most of what it uses comes from Saudi Arabia, not as perverse as shipping it from Canada although that could change once the Transmountain pipeline is built, so the fuel you are burning has already traveled far further that ...

There are no experimental studies of the toxicokinetics of gasoline per se, but there have been numerous toxicokinetic studies of the major gasoline constituents. The principal route of exposure for most individuals is inhalation. It has been shown that absorption of inhaled constituents increases with increasing molecular weight, with n-paraffins being more highly absorbed than iso-paraffins and aromatics being more highly absorbed than the corresponding paraffins. The low molecular weight constituents (butanes and pentanes) are poorly absorbed and predominantly exhaled unchanged. The higher molecular weight constituents are more efficiently absorbed, with metabolism, normally to the corresponding alcohols, and excretion in the urine becoming increasingly important. About 15% of the butanes and pentanes are absorbed with biological half-times measured in minutes. About 25% of the hexanes and 50% of the higher molecular weight constituents are absorbed with biological half-times ranging from ...

No matter how much ugly reality surrounds people whose life revolves around pot, the excuses never end. If only covers a lot ground. If only people would behave responsibly, then the world would be a loving and kind place.. The trouble is that, not only do few agree what kind and loving is, enough people tend to resent the idea that they should deprive themselves of any want, no matter how small, for the betterment of others, that bad crap inevitably happens. Especially among people whose goal is to avoid distress by chemical ingestion or make money by providing for who do. They are specialists in the easy way for themselves and the hell with anyone objecting.. The bottom line is there is no bottom line. Giving an inch is immediately followed with demands to give another. And another. And another. There will always be those who burn houses down. And anyone intending to draw a line should not delude themselves that they are in control of it.. ...
at BSHSIBTW Date: 5/10/02 11:05 AM While I am new to histology in general, we work with rat brains. I understand this lab used to freeze the brains on dry ice. The tissue always developed holes due to ice crystal formation. Now we quickly freeze either the whole brain or pieces of the brain in dry ice chilled methyl butane for 20 seconds before mounting on the freezing stage of the sliding microtome or the chuck for the cryostat. Our formalin fixed brains get soaked in 10% DMSO for an hour or so first (instead of overnight in 30% sucrose), but fresh brains go right into the methyl butane. Occasionally there are small cracks in the hypothalamus, but usually the sections are very nice ...

One other possible oxide that has not yet been synthesised is oxatetrazole (N4O), an aromatic ring.[57] Nitrous oxide (N2O), better known as laughing gas, is made by thermal decomposition of molten ammonium nitrate at 250 °C. This is a redox reaction and thus nitric oxide and nitrogen are also produced as byproducts. It is mostly used as a propellant and aerating agent for sprayed canned whipped cream, and was formerly commonly used as an anaesthetic. Despite appearances, it cannot be considered to be the anhydride of hyponitrous acid (H2N2O2) because that acid is not produced by the dissolution of nitrous oxide in water. It is rather ...
