A New Vapor Pressure Equation
The Wagner equation for prediction of vapor pressure has been modified in order to improve it accuracy. On the basis of this modifications, development of a new equation for prediction of vapor pressure is outlined. Examples of the use of the equation for obtaining vapor pressure for a total of 94 pure substance are given. The proposed equation combines simplicity and accuracy and performs as w...
متن کاملHigh-intensity vapor lamp for biological research.
A vapor arc light source has been adapted to the study of the lethal action on bacteria of near-ultraviolet (UV) and visible light. Its use makes possible much shorter exposure times than could be obtained from previously available sources. The output of radiant energy is sufficient to provide a fairly detailed action spectrum for lethality in the long-UV and visible region without the addition...
متن کاملFrequency domain fluorimetry using a mercury vapor lamp
Frequency Domain (FD) fluorimetry, capitalizes on the frequency response function of a fluorophore and offers independence from light scatter and excitation/emission intensity variations in order to extract the sample's fluorescent lifetime. Mercury vapor lamps, a common source of industrial facility lighting, emit radiation that overlaps the UV/blue absorption spectrum of many fluorophores and...
متن کاملOptical pumping of helium with arc lamp excited LNA lasers
2014 We have developed a compact and relatively inexpensive laser source at 03BB =1.083 03BCm, suitable for optical pumping in helium. The laser is made of an LNA crystal transversely pumped by krypton arc lamps. A cw power of 800 mW has been achieved at 1.083 03BCm with a 3 GHz bandwidth. A 66 % nuclear polarization has been obtained in a 3He gas. Revue Phys. Appl. 24 (1989) 827-831 AOÛT 1989,
متن کامل3D LAMP: A New Layered Panoramic Representation
In this paper a compact representation, 3D Layered, Adaptive-resolution and Multi-perspective Panorama (LAMP), is proposed for representing large scale and 3D scenes with occlusion. Two kinds of 3D LAMP representations are constructed, i.e. the relief-like LAMP and the image-based LAMP, both of which concisely represent almost all the information from a long image sequence. The relief-like LAMP...
