Male age influence on fecundity and fertility has been studied in monomorphic (inversion free) and polymorphic (with inversion) strains of Drosophila ananassae. It was noticed that in both monomorphic and polymorphic strains, females mated to old males showed greater fecundity and fertility than females mated to young or middle aged males. Thus, in D. ananassae male age effect on fitness is ind...

Background: Nonpuerperal uterine inversion is a rare medical condition that many gynecologists might not be encountered even with one case during their entire medical practice. It refers to the expulsion of uterine corpus from the dilated cervix resulting in uterus being turned inside out. There are two kinds of uterine inversion, puerperal and non-puerperal, which the second condition is less ...

L1-norm is better than L2-norm at dealing with noisy data and yielding blocky models, features crucial in many geophysical applications. In this report, we develop a hybrid-norm solver proposed by Claerbout (2009) to perform L1 regressions. The solver is tested on a 1-D field RMS velocity inversion, a 2-D regularized Kirchhoff migration inversion and a 2-D velocity analysis problem. The results...

Examining the cooling rate using impingement of air jet finds a wide application in electronic packaging and micro-scale fluid heat interaction systems, While the prediction of Nusselt profile at low nozzle-target spacing is a big issue. The plot of area average Nusselt number magnitude against the nozzle-target spacing (Z/d) shows a gradual decrement in the profile upto Z/d = 1 and beyond that...

This paper presents a new direct matrix inversion-less analysis for radial distribution systems (RDSs). The method can successfully deal with weakly meshed distribution systems. (WMDSs). Being easy to implement, direct methods (DMs) provide an excellent performance. Matrix inversion is the mean reason of divergence and low-efficiency in power flow algorithms. In this paper, the performance of t...

The quality of the migration/inversion in seismic re ̄ection is directly related to the quality of the velocity macro model. We present here an extension of the differential semblance optimization method (DSO) for 2-D velocity ®eld estimation. DSO evaluates via local measurements (horizontal derivatives) how ̄at events in common-image gathers are. Its major advantage with respect to the usual cos...
