N attempts a t an experimental approach to the problem of the mechanism of I crossing over many modifying agents have been used : temperature (PLOUGH 1917), aging (BERGNER 1928), inversions (STEINBERG 1936), mineral content (BROWNING 1949), and radiation (MULLER 1925). As diverse as are these agents, they all have one effect in common. They modify the rate of crossing over in either the region ...

A new sensitive, simple, rapid, accurate and precise method for simultaneous quantification of nebivolol HCl (NEB) and hydrochlorothiazide (HCT) in combined tablet dosage form has been developed. The method is based on the derivative spectrophotometric method at zero-crossing wavelengths. Two wavelengths 280nm (zero crossing point for NEB) and 272.2nm (zero crossing point for HCT) were selected...

Full waveform data recording the reflected laser signal from ground objects have been provided by some commercial airborne LIDAR systems in the last few years. Waveform data enable users to explore more information and characteristics of the earth surface than conventional LIDAR point cloud. An important application is to extract extra point clouds from waveform data in addition to the point cl...

Laser-induced crystallization is a new method for the design and control of the crystallization of glasses and opens a new door in the study of nucleation and crystal growth in glasses. Nonlinear optical Sm-doped β-BaB2O4 (β-BBO) crystal lines were patterned by continuous-wave Yb:YVO4 fiber laser (wavelength 1080 nm) in 8Sm2O3-42BaO-50B2O3 glass as an example, and nucleation and crystal growth ...

Magnetic properties of layered high temperature superconductors with a weak interlayer coupling in the region of the critical fluctuations are investigated in the framework of the Ginzburg–Landau approach. The sample magnetization is calculated within a perturbative approach to the second order in the interlayer coupling constant. The first order correction can be incorporated into the non-inte...

We theoretically study the orbital magnetic susceptibility produced by electron states near a crossing point of two band-contact lines in crystal. It is shown that this can have an unusual dependence on Fermi level and change noticeably with temperature when vicinity point. These features be useful detecting points The obtained results explain well-known V$_3$Si.
