A thermal and chemical degradation approach was followed to determine the precursors of pristane (Pr) and phytane (Ph) in samples from the Gessoso-solfifera, Ghareb and Green River Formations. Hydrous pyrolysis of these samples yields large amounts of Pr and Ph carbon skeletons, indicating that their precursors are predominantly sequestered in high-molecular-weight fractions. However, chemical degradation of the polar fraction and the kerogen of the unheated samples generally does not release large amounts of Pr and Ph. Additional information on the precursors of Pr and Ph is obtained from flash pyrolysis analyses of kerogens and residues after hydrous pyrolysis and after chemical degradation. Multiple precursors for Pr and Ph are recognised in these three samples. The main increase of the Pr/Ph ratio with increasing maturation temperature, which is associated with strongly increasing amounts of Pr and Ph, is probably due to the higher amount of precursors of Pr compared to Ph,...

Ennen musiikkia merkittävän osan Harrisin elämästä täytti urheilu. Hän harrasti jalkapalloa, krikettiä ja tennistä. Jalkapallossa hän oli hyvin lahjakas ja hän haaveilikin ammattilaisurasta suosikkiseurassaan West Ham Unitedissa. Hän kiinnostui rockmusiikista teini-iässä lainattuaan ystävältään muun muassa Jethro Tullin, Genesiksen ja Deep Purplen albumeita ja ryhtyi harkitsemaan urheilun jättämistä ja muusikoksi ryhtymistä. Uravalinta oli Harrisin tulevaisuuden kannalta rohkea, sillä häntä oli juuri pyydetty harjoittelemaan West Hamin kanssa seuran pelaajatarkkailijoiden toimesta.. Harris halusi alun perin opetella soittamaan rumpuja, mutta hänen kotonaan ei ollut riittävästi tilaa rumpusetille ja hän joutui luopumaan ajatuksesta. Hän aloitti kitaransoiton 17-vuotiaana kunnes hän päätti vaihtaa instrumenttinsa bassokitaraan.[1] Hän osti ensimmäisen bassonsa, 40 puntaa maksaneen Fender Precision Bassin kopion vuonna 1971.[2]. Harjoiteltuaan ostamallaan bassolla ...

Spectroscopy has been crucial for our understanding of physical and chemical phenomena. The interpretation of interstellar line spectra with radiative transfer calculations usually requires two kinds of molecular input data: spectroscopic data (such as energy levels, statistical weights, transition probabilities, etc.) and collision data. This contribution describes how such data are collected, stored, and which limitations exist. Also, here we summarize challenges of atomic/molecular databases and point out our experiences, problems, etc., which we are faced with. We present overview of future developments and needs in the areas of radiative transfer and molecular data.

The giardins are a family of approximately 30000 Mr structural proteins found in microribbons attached to microtubules in the disc cytoskeleton of Giardia. After examining the solubility of giardins in various agents, a method has been developed to extract these polypeptides and subsequently precipitate them selectively. The giardin chains are soluble in 10 mM-HEPES/EDTA buffer at high pH and low ionic strength, but become insoluble in 10 mM-MES/EDTA buffer at pH 6.7 when the ionic strength is raised above 50 mM salt. By dialysing giardin extracts in turn against dissociating and reassembly buffers, the purification is obtained of a subset of giardin chains identified by sodium dodecyl sulphate/polyacrylamide gel electrophoresis as the cytoskeleton bands 14a, 14b and 15. The structures forming under assembly conditions are all composed of fine filaments, 2-3 nm in diameter. Filaments after the first cycle of assembly are found in bundles, narrow ribbons of two or three filaments, and large ...

Imidazole, appears in a number of pharmaceuticals, is characterized by a ring structure composed of three carbon atoms and two nitrogen atoms at nonadjacent positions. The simplest member of the imidazole family is itself, a compound with molecular formula C3H4N2. Labs can produce it and its derivatives, like clotrimazole and econazole, synthetically. This allows for efficient mass production in a controlled environment.. The chemical was first prepared in 1858. Other imidazole compounds have been known longer: allantoin (discovered in 1800) and parabanic acid were prepared in 1837 from uric acid. The amino acid histidine and its decomposition product histamine have the structure, as does biotin, a growth factor for both humans and yeast.. Patients may be told to take an imidazole to treat a fungal infection because it has a broad mechanism of action and is usually easy to use.

[extract] Philosophers and scientists often describe theories, laws, and explanations as applying to the world at different levels. This idea of a level of application is often used to demarcate disciplinary or sub-disciplinary boundaries in the sciences. For instance, stoichiometric laws and quantum mechanical laws might be said to describe chemical phenomena at different levels. More generally, the idea of levels is used to distinguish more fundamental laws or theories from less fundamental ones: more fundamental theories are those that apply at more fundamental levels.

Operator Splitting methods are widely used for the numerical computation of reactive flows. The classical analysis of the error induced by such techniques is based on asymptotic expansions with respect to the splitting timestep Δt (supposed to be a small parameter). Such an assumption is unfortunately rather difficult to meet in real computations since Δt is actually much larger than the smallest physical timescales (defined by fast chemical phenomena). The usual error analysis has then to be replaced by another approach, which is associated with the multi-scale behaviour of the coupled system. We give here some theoretical indications and illustrate them with a monodimensional application in Air Pollution Modelling.

The degradation of proteins in reductively [3H]methylated mitochondrial outer membrane (MOM) transplanted into cells by a poly(ethylene glycol)-mediated process has been studied. The average rate of degradation (t1/2 24-28 h) of MOM proteins transplanted into HTC cells was not the same as for endogenous MOM proteins (t1/2 56 h), mitoplast proteins (t1/2 120 h), plasma membrane proteins (t1/2 approx. 90 h) or cytosol proteins (t1/2 75 h). The degradation of transplanted MOM proteins was inhibited to the same extent (30-45%) as that of endogenous mitochondrial and plasma membrane proteins by leupeptin and NH4Cl. No inhibition of HTC cell cytosol protein degradation by NH4Cl was observed. NH4Cl differentially inhibited the degradation of endogenous MOM and mitoplast protein subunits as shown after sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. Proteins in MOM transplanted into tissue culture cells were degraded either with t1/2 24-28 h (MRC-5, B82 and A549 cells) or with t1/2 55-70 h ...
Pantothenase (EC 3.5.1.22) from Pseudomonas fluorescens UK-1 was purified to homogeneity as judged by disc-gel electrophoresis and isoelectric focusing. The purification procedure consisted of four steps: DEAE-Sephadex chromatography, (NH4)2SO4 precipitation, hydroxyapatite chromatography and preparative polyacrylamide-gel electrophoresis. Gel filtration on Ultrogel AcA 34 was used to determine the molecular weight, and sodium dodecyl sulphate/polyacrylamide-gel electrophoresis to study the subunit molecular weight. The enzyme appeared to be composed of two subunits with mol.wts. of approx. 50000 each. The total mol.wt. of the enzyme was thus about 100000. The isoelectric point was 4.7 at 10 degrees C. ...
