objective: evaluation of the effects of different doses of antioxidant taurine on oxidative stress and human sperm parameters following cryopreservation. materials and methods: the semen of 20 fertile men were divided to 5 aliquot, one part considered as a fresh after analysis of standard semen parameters (motility, abnormal morphology, viability) and protamine deficiency, dna damage and measu...

the pathogenesis of equine grass sickness (egs) has not fully understood. a better understanding of the exact pathogenesis of diseases can help to make an accurate diagnosis. previous studies reported some pathological damage of neuronal cells in egs patients. in this study, primarily cytotoxicity of serum from three clinically egs-diagnosed horses on pc12 tet-off (pto) cells was assessed. subs...

We propose to study quark-hadron duality in meson electroproduction. While duality between inclusive electron-hadron scattering in the resonance and deep inelastic regimes (Bloom-Gilman or quark-baryon duality) is well established, the existence of a similar duality in meson electroproduction has not yet been tested. In the inclusive case, duality implies that single-quark scattering governs th...

introduction: tegrity is the most important component for transferring genetic information sperm dna fragmentation is considered a component of male infertility. its assessment comprises conventional semen analysis of which emphasis is placed on its evaluation in fertility clinics. in this study, we investigate the relationship between sperm parameters of motility, morphology, concentration, an...

this study analyzed the determinants of the productivity of smallholder arable crop farmers with a particular focus on land fragmentation using the simpson index as measures of land fragmentation in imo state of nigeria. data collected by using structured questionnaire and interview schedules were analyzed using simple descriptive statistics; simpson index and regression analysis. results showe...

The production of final state photons in deep inelastic scattering originates from photon radiation off leptons or quarks involved in the scattering process. Photon radiation off quarks involves a contribution from the quark-to-photon fragmentation function, corresponding to the non-perturbative transition of a hadronic jet into a single, highly energetic photon accompanied by some limited hadr...

play a similarly fundamental role as those of the corresponding crossed ‘spacelike’ deep-inelastic scattering (DIS) process ep → eX . Their interpretation in terms of scale-dependent fragmentation functions D f (z,Q ), the ‘time-like’ counterparts of the parton distribution functions fH(x,Q ) of a hadron H , hence provides a further important, complementary test of perturbative QCD. Furthermore...

Aerodynamic breakup of drops as a form of secondary atomization has wide scientific and engineering applications. Previous experimental studies using point-wise and two-dimensional (2D) measurement techniques are unable to provide three-dimensional (3D) spatially-resolved information about the breakup without significant experimental repetition. Digital in-line holography (DIH) has unique acces...
