ISSN: 1750-3841Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionProcess Engineering, Biotechnology, Nutrition TechnologyNotes: Inoculation of kimchi, a Korean style fermented Chinese cabbage, with Propionibacterium freudenreichii ss. shermanii (ATCC No. 13673) increased vitamin B12 production to a maximum of 102 ng/100g from 47 ng/100g in the control at 1 wk of fermentation at 4°C. Soy flour (0.5%) or beef extract (0.05%), added as protein sources to the inoculated kimchi, further increased the vitamin activity to 197 and 203 ng/100g, respectively, at 1 wk. The fresh, unfermented kimchi contained 16.8 mg of ascorbic acid per 100g and the vitamin decreased at a constant rate during the first 5 wk of fermentation.Type of Medium: Electronic ResourceURL: -

Published 1992Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: Multiphoton resonance ionization (MPRI) spectroscopy has been employed to investigate the ejection mechanisms of neutral and ionic particles from an ion-bombarded NaCl{100} single crystal. The results are used to reveal the similarities and the differences between ion bombardment and electron irradiation of alkali halides. The mass spectra of neutral species and positive and negative ions have been measured. The yield of Na+ ions is found to be two orders of magnitude higher than in measurements with electron bombardment. It is suggested that the secondary ions are created by direct emission from the collision cascade. The ejection of neutral Na atoms is observed to be very sensitive to the temperature of the target, the angle of incidence, and the state of the surface as determined by the time-of-flight (TOF) measurements. In particular, it is found that most of the neutral Na atoms are emitted with thermal energies, which indicates that desorption via electronic transitions dominates over ejections from collision cascades. The relative yield of the collisional component to the thermal component is found to vary significantly as the surface structure is modified. This investigation emphasizes the importance of measurements with low incident-ion dose which allows one to decouple the single ion/surface interaction from the accumulative effect of ion-induced surface modifications.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We find that the incorporation of Ge into SiC during the metalorganic chemical vapor deposition growth process improves the crystalline quality of SiC films grown on Si (111) substrates at 1000 °C. Secondary ion mass spectroscopy results indicate that Ge does not act as a surfactant, but rather it incorporates throughout the entire film. Transmission electron microscopy results show that high quality, single crystalline SiC films of up to 80 nm thickness are repeatably obtained for GeH4 flow rates ranging from 20 to 30 sccm. Higher GeH4 flow rates induce twinning and result in a reduced growth rate and increased surface roughness. Lower GeH4 flow rates result in polycrystalline and/or amorphous-like SiC films similar to what is normally obtained at such a low growth temperature. We discuss the role of Ge during growth and how its presence in the reactor during Si substrate carbonization results in higher quality SiC films than normally achieved for growth temperatures of 1000 °C.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Ni/WSi/Ti/Pt Ohmic contacts to n-SiC were investigated as a function of annealing temperatures up to 1000 °C. Annealing at temperatures between 950 and 1000 °C yielded excellent Ohmic behavior. At these temperatures the contact–SiC interface was smooth, defect free, and characterized by a narrow Ni2Si reaction region. The annealed contacts possessed atomically smooth surface morphologies and exhibited minimal contact expansion. The residual carbon, resultant from SiC decompositon and reaction with Ni to form Ni2Si, was constrained by reaction with the WSi and Ti layers forming carbide phases of W and Ti spatially distant from the metal semiconductor interface. Our results demonstrate that the Ni/WSi/Ti/Pt composite Ohmic contact maintains the desirable electrical properties associated with Ni contacts and possesses excellent interfacial, compositional, and surface properties which are required for reliable high power and high temperature device operation. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1471-4159Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Abstract: A method for the measurement of 3H-monoamine [noradrenaline (NA) and 5-hydroxytryptamine (5-HT)] uptake into intact brain following intracerebroventricular injection is described. Most of the accumulated monoamine was associated with nerve terminals (synaptosomes). Radioactivity in the synaptosomal fraction was retained by 0.45-μm filters and was osmotically sensitive, features indicative of accumulation within particles rather than binding to membranes. [3H]5-HT associated with synaptosomes was reduced in animals pretreated with the neurotoxin 5,7-dihydroxytryptamine, in parallel with a reduction in endogenous 5-HT levels. Oral administration of tricyclic antidepressants including clomipramine, desipramine, and imipramine inhibited the synaptosomal accumulation of 3H-monoamines. Overall, the features of the accumulation of 3H-monoamines, after intracerebroventricular administration, displayed many of the characteristics expected of a physiological monoamine reuptake system.Type of Medium: Electronic ResourceURL: -

ISSN: 1471-4159Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Abstract: The binding of the unselective opioid antagonist [3H]diprenorphine to homogenates prepared from rat brain and from guinea-pig brain and cerebellum has been studied in HEPES buffer containing 10 mM Mg2+ ions. Sequential displacement of bound [3H]diprenorphine by ligands with selectivity for μ-, 8- δ, and k-opioid receptors uncovers the multiple components of binding. In the presence of cold ligands that occupy all μ-, δ-, and k-sites, opioid binding still remains. This binding represents 20% of total specific sites and is displaced by naloxone. The nature of these undefined opioid binding sites is discussed.Type of Medium: Electronic ResourceURL:
