ISSN: 1365-3091Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: GeosciencesNotes: Based upon studies of natural quartz and upon laboratory experiments on mechanical and chemical destruction of quartz, it was established that the statistical density characteristics of detrital quartz change during sedimentary processes. Grains with defective structure, gas-liquid inclusions, inclusions of organic matter and other lighter minerals have lesser densities, whereas grains with inclusions of heavier minerals have larger densities than those of optically pure grains. The susceptibility to destruction is less for optically pure grains than for grains with lower or higher density. This is responsible for the increasing maturity of quartz sand during weathering and transport as indicated by the increasing percentage of optically pure grains. Mathematical modelling of the dynamics of this process was carried out.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We introduce a technique for measuring the refractive indices of a crystal and apply it to measure the dispersion curve of KTiOPO4. The refractive index evaluation is based on measurement of the Bragg reflection wavelength of periodically segmented waveguides close to cut-off conditions. The measurement error is found to be less than 10−4. Second harmonic generation and optical parametric oscillation in periodically poled KTiOPO4 enable us to extend the measurement to a wide wavelength range. A room temperature Sellmeier type equation for the dispersion curve nz(λ) of flux-grown KTiOPO4 in the entire transparency range of the crystal is determined. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1994Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: A MEVVA (metal vapor vacuum arc) ion source has been made and tested at the Institute of Theoretical and Experimental Physics (ITEP), Moscow. The ions are created in the plasma formed from the cathode metal vapor of a vacuum arc discharge. An ion beam current of about 200–400 mA in repetitively triggered pulses of width 0.1 ms has been obtained. The ion charge state distributions have been measured for seven elements (Be,C,Al,Fe,Cu,Zr,W) and they are in reasonable agreement with results of other workers. The MEVVA ion source is simple to operate and has a reliability acceptable for use as an ion source for ITEP synchrotron injection.Type of Medium: Electronic ResourceURL: -

ISSN: 1471-0528Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Plasma oestradiol showed a two- to three-fold rise above the mean basal level by six hours after a single intravenous injection of synthetic Luteinizing Hormone and Follicle Stimulating Hormone Releasing Hormone (LH-RH/FSH-RH) in nine out of twelve patients with secondary amenorrhoea. Of the remaining three patients, two had persistently high basal plasma gonadotrophins in keeping with a diagnosis of premature menopause and one patient had secondary amenorrhoea of seven years' duration. It is suggested that a six-hour plasma oestradiol estimate be used as the endpoint of the LH-RH/FSH-RH test in order to assess the pituitary-ovarian axis. If a less than two-fold increase in plasma oestradiol is found, pituitary reserve can be more intensively studied by assaying plasma follicle stimulating hormone (FSH) and luteinizing hormone (LH).Type of Medium: Electronic ResourceURL: -

Published 1996Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: It is shown that secondary electron emission current from ferroelectric domains with opposite directions of spontaneous polarization in ferroelectric KTiOPO4 crystals (KTP) is substantially asymmetric. The effect originates from asymmetry of elementary electron processes in noncentrosymmetric crystals. A nondestructive method of ferroelectric domain observation by secondary electron emission microscopy in KTP crystals is developed, which enables observation of a domain grating in periodically poled KTP frequency doubler. © 1996 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1986Staff ViewISSN: 1468-2494Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Stratum corneum moisturization was measured by two instruments simultaneously on the same subjects at different body sites. One instrument is based on the 1 GHz focused mirowave dielectric measurement; the other instrument measures impedance at 16 Hz.A linear relationship r = 0.86 was observed between the measurements by the two above-mentioned instruments. The 1 GHz focused microwave measurement is more accurate in measuring water concentration in the stratum corneum, especially in the upper layers relevant to “moisturization”; it is, however, an expensive research instrument. The low frequency impedance measurement involves a much simpler, cheaper and portable instrument which can be used routinely to evaluate ‘moisturization’ for the purpose of skin classification under field conditions.Comparaison de divers appareils de mesure de I'hydratation de la couche cornee〈section xml:id="abs1-2"〉〈title type="main"〉ésuméL'hydratation de la couche cornée a été mesurée simultanément par deux appareils sur plusieurs sites de mêmes sujets: le front, la face et les membres. Un appareil est basé sur la mesure par micro ondes, I'autre mesure I'impédance à 16 Hz.On observe une relation linéaire, r= 0.86, entre les mesures effectuées par les deux appareils ci-dessus. L'appareil à micro ondes est plus précis pour la mesure de la concentration en eau de la couche cornée et plus spécialement dans les couches supérieures qui sont importantes pour I'hydratation, mais cet appareil est onéreux. La mesure des impédances à basse fréquence utilisé un appareil portable, simple et bon marché qui peut être utilisé en routine pour évaluer I'hydratation dans le but de classer des types de peaux sur le terrain.II n'est pas toujours possible de comparer des appareils diffeérents sur les mêmes personnes et dans le même temps et il est encore plus difficile d'obtenir des donneées sur un nombre de personnes de type diffeérent. Nous suggeérons d'utiliser à I'avenir une meéthode de comparaison diffeérente basée sur I'application d'un traitement standard bien défini, qui pourrait par example consister en I'application pendant une heure d'une solution à 2% de glycérine sur I'avant bras, avant la mesure.Ces données, avec la connaissance de la distribution des valeur du prétraitement pour les divers appareils, permettraient également la comparaison et la validation des différentes méthodes.Type of Medium: Electronic ResourceURL: -

Published 2000Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: Frequency doubling of a diode-pumped Nd:YAG laser in 1 and 2 cm long periodically poled KTiOPO4 wafers has been investigated. Up to 60% doubling efficiency has been achieved. The good agreement obtained between measured results and those calculated by numerical integration of the coupled wave equations demonstrate that the efficiency is limited by the basic process of backconversion and dephasing rather than by thermal effects. © 2000 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1750-3841Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionProcess Engineering, Biotechnology, Nutrition TechnologyNotes: Lipid material from skin, depot fat, and dark and white meat from broiler-type male chickens was fractionated into neutral lipids and phospholipids by column chromatography. The fatty acids of these fractions were analyzed by gas-liquid chromatography.Muscle tissues contained relatively larger quantities of phospholipids than did skin and depot fat. Neutral lipids and phospholipids had similar percentages of unsaturated fatty acids. Some 18 different fatty acids were found in the neutral lipids, and 22 fatty acids were found in the phospholipid fraction. The composition of fatty acids in the neutral lipids was similar in the four tissues. Phospholipids from muscle tissues contained more long-chain fatty acids than phospholipids from skin and depot fat. Arachidonic acid was found to be one of the major fatty acids in the phospholipid fraction.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Periodically segmented waveguides were fabricated by the ion exchange process in KTiOPO4. The waveguides were characterized by measuring the spectra of the transmitted and reflected guided infrared light and of the second-harmonic-generated power. The near-field distribution of the fundamental and second-harmonic wave was also investigated. Infrared to blue light conversion efficiency up to 250% W−1 cm−2 was obtained. Waveguide characteristics were calculated by replacing the segmented structure with an equivalent continuous waveguide. Good agreement between the calculated and measured values was obtained.Type of Medium: Electronic ResourceURL: -
