Abstract: The present invention relates to a method for preventing transmission of influenza, wherein said method comprises administering an effective amount of a compound to a patient having an influenza virus infection, herein referred to as “index patient”, wherein the compound has one of the formulae (I) and (II), or its pharmaceutically acceptable salt. The compound to be used in the present invention reduces infectivity of the influenza virus of the index patient, and therefore, reduces the risk of the index patient to trigger an influenza epidemic or an influenza pandemic as compared to a control patient.

Abstract: A personal dosimeter for measuring the average concentration of undesirable contaminants gases such as nitrogen oxide includes a gas permeable web-like wafer formed of a material inert to polyamine. The wafer has a surface area having a numerical value at least one thousand times the value of the axial width of the wafer. The wafer is soaked in an absorptive medium not containing the ambient contaminant gas to be measured. The wafer, so soaked, is inserted within a gaseous impermeable housing from which the wafer may be selectively release and re-inserted. During an interval of release of the wafer, it is exposed for a predetermined interval of time to the ambient atmosphere. After re-insertion, the dosimeter is taken to an analysis site at which the wafer is removed and the molar concentration of products reaction with the atmospheric contaminant is measured.

Abstract: An automatic sling release serving for the automatic disengagement of a sg, such as a chain, a rope, or a strap from a hoisting hook at the moment of relieving the sling of the weight of the load. The device has a load sustaining body with a first, sling engaging hook thereon. A releasing arm is pivotally mounted on the body, the releasing arm having a portion thereof in the form of a second hook positioned close to the first hook and partially overlapping it. The second hook has two working faces, i.e., an upper sling end engaging face and a front thrusting face, in the basic unloaded position of the releasing arm the front thrusting face projecting beyond the outer edge of the first hook on the load sustaining body.
