    Notes: Abstract A qualitative comparison was made of the genera of fungi associated with creeping bentgrass turf (Agrostris palustris) plots either nonsprayed or sprayed with six fungicides for 4 or 5 successive years. The fungicides used were: Fore (manganese ethylene bisdithiocarbamate plus zinc ion) Actidone-Thiram (3[2-(3, 5-dimethyl-2-oxycyclohexyl)-2-hydroxy-ethyl]) glutarimide plus tetramethyl thiuram disulfide); Dyrene (2, 4-dichloro-6-0-chloroanillino-s-triazine; Kromad plus Calaclor (5% cadmium sebacate, 5% potassium chromate, 1% malachite green, 0.5% auramine, 16c tetramethyl thiuram disulfide plus 60% mercurous chloride, 30% mercuric chloride); PMA plus Thiram (phenylmercuric acetate plus tetramethyl thiuram disulfide); and Tersan OM (hydroxymercuric chlorophenol plus tetramethyl thiuram disulfide). None of the fungicides had any significant effect on the distribution of fungal genera studied.

    Measurement of laser light thomson-scattered from a cooling electron beam (1987)

    Notes: Abstract First results are presented from an experiment scattering laser light from a relativistic electron beam. The 5 cm diameter continuous electron beam of 28 keV kinetic energy and 2.6 A current presents an electron gas of a density of 8×107 cm−3, from which 20 ns pulses of laser light (490 nm) were scattered at a repetition rate of 15 Hz and an average power of 20 mJ per pulse. The Doppler-shifted wavelength of photons backscattered under 180° was analysed with a Fabry-Perot interferometer. This technique provides, for the first time, a non-destructive measurement of the velocity distribution in an electron beam radially resolved in space. The results presented here comprise the direct measurement of the absolute electron energy and the degree of space-charge compensation in the electron beam. The determination of an upper bound of 10−2 for the ratio of longitudinal to transverse electron temperature implies the first direct measurement of a flattened velocity distribution.

    Über die Stabilität der Strömung einer elektrisch leitfähigen, reibungsfreien Flüssigkeit im zylindrischen Ringraum unter dem Einfluß eines axialen Magnetfeldes (1970)

    Description / Table of Contents: Summary The stability-theory of helical flows in the narrow gap between coaxial cylinders is extented to the hydromagnetic case. The inviscid fluid is supposed to be ideally conducting and is influenced by an axial magnetic field. The investigation of the stability leads to an eigenvalue-problem of a linear differential-equation of second order, which can be solved analytically only for special disturbances. For arbitrary disturbances numerical methods are required. The results show that in the presence of a magnetic field weak instabilities always exist.
    Notes: Übersicht Es wird die Theorie der Stabilität spiraliger Strömungen im schmalen zylindrischen Ringraum auf den hydromagnetischen Fall erweitert. D. h. die reibungsfreie Flüssigkeit wird zusätzlich als elektrisch unendlich leitfähig vorausgesetzt und steht unter der Wirkung eines axialen Magnetfeldes. Die Stabilitätsuntersuchung führt auf ein Eigenwertproblem einer linearen Differentialgleichung zweiter Ordnung. Dieses Problem kann nur für spezielle Störungen analytisch gelöst werden. Für allgemeine Störungen müssen die Eigenwerte numerisch bestimmt werden. Die Rechnung ergibt, daß in Anwesenheit eines Magnetfeldes immer schwach angefachte Störungen auftreten.

    Description / Table of Contents: Contents Calculating transients in power systems it is advantageous to use symmetrical components. The example of the most common three-phase bridge converter shows that also current converters can be described in space phasors. With respect to the characteristics of conducting valves the networks and the conditions of firing and commutation ending are deduced. Numerically calculated results agree with measurements. A parameter study shows the typical space phasor curves of bridge converter currents.
    Notes: Übersicht Dynamische Netzberechnungen lassen sich vorteilhaft in Drehstrom-Modalkomponenten durchführen. Das Beispiel der meistgebräuchlichen Drehstrom-Brückenschaltung zeigt, daß auch Stromrichter mit Raumzeigern beschrieben werden können. Unter Berücksichtigung der Eigenschaften stromführender Ventile werden die Ersatzschaltpläne sowie die Zünd- und Löschbedingungen in Modalkomponenten hergeleitet. Die Ergebnisse numerischer Berechnungen stimmen mit Messungen überein. Eine Parameterstudie zeigt die für Brückenschaltungen typischen Stromortskurven in Modalkomponenten.

    Ifosfamide in pediatric malignant solid tumors (1989)
    Springer
    Cancer chemotherapy and pharmacology 24 (1989), S. S24 
    Details
    ISSN: 1432-0843
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Ifosfamide/mesna was given to 97 patients who had malignant solid tumors diagnosed before they were 21 years of age. Patients received 1.6 g/m2 ifosfamide dailyx5, given i.v. over 15 min, followed by 400 mg/m2 i.v. mesna at 15 min and 4 and 6 h after ifosfamide. Responses were noted in patients with osteosarcoma, Ewing's sarcoma, rhabdomyosarcoma and other soft-tissue sarcomas, rhabdoid tumor, neuroblastoma, Wilm's tumor, primitive neuroectodermal tumor, retinoblastoma, germ-cell tumors, and B-cell lymphoma. Toxicity included mild to moderate nausea and vomiting, transient, reversible myelosuppression, transient elevations of serum blood urea nitrogen (BUN) and creatinine and liver enzymes, infections, and self-limiting neurotoxicity characterized by changes in mental status, motor dysfunction, cranial nerve palsy, cerebellar dysfunction, and seizures. Neurotoxic symptoms were generally seen in patients who had previously received cisplatin. Ifosfamide is an important alkylating agent that should be combined with other agents in phase II and III trials. Alternate dose schedules should also be investigated.

    A study of the influence of pH on the buccal absorption and renal excretion of procainamide (1974)

    ISSN: 1432-1041
    Keywords: Procainamide ; buccal absorption ; renal excretion ; urine ; pH

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The buccal absorption of procainamide was studied in 4 normal, male volunteers over a pH range of 5–11. In another investigation the same 4 volunteers collected their urine for 24 h after taking 250 mg of procainamide hydrochloride orally on 3 separate occasions, during which urine pH was uncontrolled, acidified by ammonium chloride ingestion or alkalinised by sodium bicarbonate ingestion. The procainamide remaining after buccal absorption and present in the urine samples was determined spectrophotometrically. It was found that neither the buccal absorption nor the renal excretion of procainamide was substantially altered by changes in pH.

    Notes: Summary Crops grown with flood irrigation on slowly draining clay soils are subject to periods of waterlogging during and after each irrigation. The aim of this experiment was to quantify crop responses to these short-term waterlogging events and to assess the modifying effect of different agronomic practices. Maize was grown in undisturbed (U) and repacked (R) profiles of clay loam soil encased in steel cylinders (0.75 m diameter × 1.4 m deep). Two levels of N (high (HN) 300 kg N ha−1, and low (LN) 150 kg N ha−1) were applied as a split dressing. Three periods of flooding (F) of 72, 72 and 48 h were imposed on half the treatments beginning on days 40, 54 and 68 respectively after sowing. The other irrigation regime (C) kept the profile well watered but avoided surface inundation.
