assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Routine assessment of motility of ejaculated stallion spermatozoa using a novel computer-assisted motility analyzer (QualispermTM)

Visual motility analysis is the basis for routine quality evaluation of stallion semen, although its prognostic value for fertilizing ability is considered low. The present study evaluated the ability of a novel computer-assisted motility analyzer (QualiSpermTM) to determine the motility and velocity of ejaculated, extended stallion spermatozoa (collected from 10 stallions, 3 ejaculates/stallio...

Motility of spermatozoa at surfaces.

The hydrodynamic basis for the accumulation of spermatozoa at surfaces has been investigated. The general conclusion is that when spermatozoa arrive at a surface, they will remain there if the vector of the time-averaged thrust is directed towards that surface. This can arise in two basic ways. First, consider spermatozoa that maintain a three-dimensional waveform and roll (spin) as they progre...

Motility evaluation of human spermatozoa

In this contribution we investigate the applicability of photon correlation techniques as a clinical tool for the evaluation of motility parameters of undiluted human sperm. Measurements on semen samples, selected visually for 'good' motility, yielded reproducible estimates of the fraction motile spermatozoa and the mean speed of the motile cells.

Formation of Hydrogen Peroxide by Chilled Goat Spermatozoa and the Effects of Dead Spermatozoa on Motility Characteristics

In this study, the formation of hydrogen peroxide (H2O2) by chilled goat spermatozoa was measured. Furthermore, the effects of dead spermatozoa on motility characteristics were studied. Fresh collected ejaculates from five Shami bucks were centrifuged and virtually all seminal plasma was removed. A part of the collected spermatozoa was killed by two ways: the first by repe...
