    Notes: Cubic-meter-sized antineutrino detectors can be used to non intrusively, robustly, and automatically monitor and safeguard a wide variety of nuclear reactor types, including power reactors, research reactors, and plutonium production reactors. Since the antineutrino spectra and relative yields of fissioning isotopes depend on the isotopic composition of the core, changes in composition can be observed without ever directly accessing the core itself. Information from a modest-sized antineutrino detector, coupled with the well-understood principles that govern the core's evolution in time, can be used to determine whether the reactor is being operated in an illegitimate way. A group at Sandia is currently constructing a 1 m3 antineutrino detector at the San Onofre reactor site in California to demonstrate these principles. © 2002 American Institute of Physics.

    Notes: Summary The decrease of alcohol concentration in the blood and the excretion of alcohol in the urine were measured before and during the administration of levulose in 14 volunteers. The influence of alcohol on the metabolism of levulose was investigated. The experiments show that levulose accelerates the oxydative catabolism of alcohol in man.

    Notes: Abstract This is a preliminary investigation into a recently defined urological disorder occurring in a subgroup of women with “urethral syndrome” suggestive of pelvic floor muscular (PFM) dysfunction. Symptoms include straining to void, urgency, frequency, hesitation, incontinence and/or retention, and subpubic pain. Finding neither bladder nor urological abnormalities, urologists may consider these women emotionally unstable without organic cause for their symptoms. However, their distress may be a consequence rather than a cause of their voiding problems. Sixteen female urological patients were matched with 16 asymptomatic controls to investigate PFM functioning, psychological status, and symptomatology. Results showed heterogeneity of symptomatology and little elevation of depression or anxiety when comparing patients with controls. Hypotheses of muscular abnormality were confirmed. Patients evidenced poor control over tensing and relaxing PFM, elevations of PFM activity under various conditions, and chronic pain as a prominent symptom. Treatment approaches specifically designed to address PFM dysfunction are discussed.

    Description / Table of Contents: Synthesis and Stability of Triorganostannylalkyl Sulphonic AcidsSodium triorganostannylalkylsulphonates R3Sn(CH2)nSO3Na(1-4) are obtained by reaction of triorganostannylsodium with sodium halogenoalkylsulphonates or propane sulton in liquid ammonia. 1-4 can be converted by ion-exchange in the free sulphonic acids R3Sn(CH2)n SO3H(9-12). 9-12 are of limited stability and undergo cyclocondensation reactions with formation of the cyclic triorganotin alkanesulphonates .
    Notes: Natrium-triorganostannylalkylsulfonate R3Sn(CH2)nSO3Na (1-4) werden durch Umsetzung von Natrium-triorganostanniden mit Natrium-halogenoalkylsulfonaten oder Propansulton in flüssigem Ammoniak erhalten. Durch Ionenaustausch können 1-4 in die freien Sulfonsäuren R3Sn(CH2)nSO3H (9-12) überführt werden.9-12 sind von begrenzter Stabilität und unterliegen Cyclokondensationsreaktionen unter Bildung der cyclischen Alkylsulfonsäure-triorganostannylester .
