    Prepulse suppression in microwave pulse-compression cavities (1986)
    [S.l.] : American Institute of Physics (AIP)

    Notes: It is possible to generate high-power microwave pulses with fast rise time by using resonant cavities to obtain power gain from pulse compression. In the usual case, especially when normal-conducting cavities are used, the principal output pulse from a pulse-compression device is preceded by a precursor signal that may be only 40 dB below the main pulse. For some applications this large a prepulse is unacceptable. We have developed a prototype normal-conducting, x-band, pulse-compression cavity in which the prepulse is suppressed by more than 70 dB. When this cavity is driven by a 20-kW source, output pulses with 200-kW peak power, 5-ns pulse width, and sub-nanosecond rise time can be obtained. We have also built an s-band cavity that has produced pulses of 5-ns width, 200-MW peak power, and under 3-ns rise time. The s-band cavity is typically driven at 5–10 MW and has a prepulse that can be more than 80 dB below the peak of the main pulse.

    Calorimetric Studies on Whey Freeze Concentration (1983)

    Notes: The freezing point of whey was determined at 3,5, 10,15, and 20% solids content in an automatic Osmometer, and effective molecular weight of the solute was determined to be 235 using freezing point depression equations. Differential Scanning Calorimetery was used to estimate the specific heat of whey in the temperature range -40 to 20°C. The frozen water fraction and refrigeration requirements are predicted as a function of temperature. Correlations of enthalpy and the freezing point of whey are presented. With these correlations, energy required for freezing whey can be computed. The application of therm odynamic data to whey freeze concentration is demonstrated.

    Regulation of Glial Cell Line-Derived Neurotrophic Factor Release from Rat C6 Glioblastoma Cells (1998)
    Oxford, UK : Blackwell Science Ltd

    Notes: Abstract: We have monitored glial cell line-derived neurotrophic factor (GDNF) secretion from rat C6 glioblastoma cells by ELISA. Representative cytokines, neurotrophins, growth factors, neuropeptides, and pharmacological agents were tested for their ability to modulate GDNF release. Whereas most factors tested had minimal effect, a 24-h treatment with fibroblast growth factor-1, −2, or −9 elevated secreted GDNF protein levels five- to 10-fold. The proinflammatory cytokines interleukin-1β, interleukin-6, tumor necrosis factor-α, and lipopolysaccharide elevated GDNF release 1.5- to twofold. Parallel studies aimed at elucidating intracellular events that may regulate GDNF synthesis/release demonstrated the involvement of multiple signaling pathways. GDNF levels were increased by phorbol 12,13-didecanoate (10 nM) activation of protein kinase C, the Ca2+ ionophore A23187 (1 µM), okadaic acid (10 nM) inhibition of type-2A protein phosphatases, nitric oxide donors (1 mM), and H2O2 (1 mM)-induced oxidative stress. Elevation of cyclic AMP levels by either forskolin (10 µM) or dibutyryl cyclic AMP (1 mM) repressed GDNF secretion, as did treatment with the glucocorticoid dexamethasone (1 µM). Our results demonstrate that diverse biological factors are capable of modulating GDNF protein levels and that multiple signal transduction systems can regulate GDNF synthesis and/or release.

    Nutritional and chemical changes in heated casein II (1975)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The Relative Nutritive Value (RNV), microbiologically available amino acids, Net Protein Utilization (NPU) and pepsin digestibility (used to predict NPU for fish protein concentrates limited by methionine) were determined for heated casein samples. The microbiological availabilities of seven amino acids fell uniformly and both available methionine and available isoleucine correlated with RNV. Microbiological availabilities were higher than chemically determined values reported previously and an explanation of this has been given. The pepsin digestibility method did not predict the NPU or RNV of severely heated casein and possible reasons for this have been discussed.

    Nutritional and chemical changes in heated casein (1974)

    Notes: Samples of commercial casein were processed either in solution or dry at temperatures between 100° and 130° for up to 8 hr. Denaturation (loss of solubility) occurred mainly at 120° and 130° and was preceded by darkening and by changes in gel filtration pattern, which indicated that molecular association had taken place. In samples subjected to severe heat treatment there were significant losses of aspartic acid, threonine, serine, cystine, histidine and lysine but apparent increases in glycine and alanine. The relationships between the various changes are discussed.

    Multiple arc ion sources for heavy ion fusion : International conference on ion sources (1990)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Heavy ion fusion requires high current density, low-emittance ion sources that are reliable and long lived. We report experimental and simulation results on the performance of carbon arc ion sources intended for use in a scaled induction linac experiment. These sources use a planar electrostatic plasma switch to prevent plasma from entering the extraction gap before the extraction voltage pulse is applied. This provides good beam optics for short pulse extraction. Measurements of current density and emittance are presented. Both double-slit and channel plate-pepper pot techniques are used for emittance measurement. Data presented are from a compact three-arc source with plasma coupling of the cathodes. Data on lifetime and multiple arc triggering are also presented. The plasma switch performance has been modeled with a 2D explicit electrostatic particle-in-cell code. Results showing plasma shutoff phenomena and behavior during extraction are presented. A 2D steady-state ion flow model is also used to predict the optimum plasma switch geometry for producing minimum emittance generation at the switch surface.
