Radar principles

Discussed here is a kind of radar called atmospheric radar, which has as its target clear air echoes from the earth's atmosphere produced by fluctuations of the atmospheric index of refraction. Topics reviewed include the vertical structure of the atmosphere, the radio refractive index and its fluctuations, the radar equation (a relation between transmitted and received power), radar equations for distributed targets and spectral echoes, near field correction, pulsed waveforms, the Doppler principle, and velocity field measurements

Linear programming analysis of the RR-parity violation within EDM-constraints

The constraint on the $R$-parity violating supersymmetric interactions is discussed in the light of current experimental data of the electric dipole moment of neutron, $^{129}$Xe , $^{205}$Tl, and $^{199}$Hg atoms, and YbF and ThO molecules. To investigate the constraints without relying upon the assumption of the dominance of a particular combination of couplings over all the rest, an extensive use is made of the linear programming method in the scan of the parameter space. We give maximally possible values for the EDMs of the proton, deuteron, $^3$He nucleus, $^{211}$Rn, $^{225}$Ra, $^{210}$Fr, and the $R$-correlation of the neutron beta decay within the constraints from the current experimental data of the EDMs of neutron, $^{129}$Xe, $^{205}$Tl, and $^{199}$Hg atoms, and YbF and ThO molecules using the linear programming method. It is found that the $R$-correlation of the neutron beta decay and hadronic EDMs are very useful observables to constrain definite regions of the parameter space of the $R$-parity violating supersymmetry.Comment: 24 pages, 6 figure

Constraint on R-parity violating MSSM at the one-loop level from CP-odd N-N interaction

Minimal supersymmetric standard model with R-parity violation (RPVMSSM) contributes to the P-, CP-odd four-quark interaction. The P-, CP-odd four-quark interaction is constrained by the new 199Hg EDM experimental data. It is then possible to constrain R-parity violating (RPV) couplings from the 199Hg EDM data. In this talk, we analyze the RPV contribution to the P-, CP-odd four- quark interaction at the one-loop level to give constraints on RPV parameters.Comment: To appear in the proceedings of International conference on the structure of baryons: BARYONS'10, Osaka, Japan, 7-11 Dec 201

Studies on respiratory humidity,pt.1.

A photo tube dew-point hygrometer is used for measuring humidity of respiratory gases, which are in varying conditions. It makes it possible to make an accurate, precise, continuous and automatic recording of the dew point of gas flows. The most notable features of this device are: (1) Simplicity of calculating absolute humidity, since the humidity is indicated with dew point. (2) Calibration is easy and reliable. (3) Performance is stable, and its operation and maintenance are simple. (4) Indication is correct and unaffected by temperature. (5) There is good response to any quick changes in humidity. (6) There is continuous and automatic recording of humidity, especially with simultaneous temperature measurements on the same paper. (7) Impurities such as the vapors of organic substances or volatile agents do not affect the performance. Simple wiping can eliminate the disturbance from mirror contamination. (8) The entire apparatus is on a cart and easily movable. This device provides a new method of studying the functional relationship between humidity and various respiratory states, and it is hoped it will contribute much to physiological and clinical investigations. The principle and structure of the &#34;automatic D.P. hygrometer&#34;, the apparatus and method for practical hygrometry and obtained results are described and discussed.</p
