We discuss the possibility of extracting |V cb | from the future measurement at LHC of the B c → J/ψ µ + ν decay rate followed by the leptonic decay J/ψ → µ + µ −. We examine in detail the influence of the measurement of the muons' momenta and vertex reconstruction in the final uncertainty of |V cb |, as well as the required theoretical inputs at both the production and weak decay level, and th...

FOOT (FragmentatiOn Of Target) is an applied nuclear physics experiment that aims at a full characterization of the fragmentation processes interest for Particle Therapy and Radiation Protection in Space. The program foresees set measurements direct inverse kinematics using particle beams targets with composition similar to human tissues spacecraft shielding materials. final goal measurement do...

 Traditional morphometric measurements and meristic counts were used to investigate the hypothesis of population fragmentation of Mash mahi, Aspius aspius taeniatus (Eichwald, 1831) among two fishing areas in southern Caspian Sea basin(Tonekabon:32 specimens  and Sari:34 specimens ). Univariate analysis of variance showed significant differences between the means of the two groups for 12 out of...

background: sperm dna fragmentation is known as an important cause of male infertility. the influence of sperm dna damage on reproductive potential has been subject of many studies indicating various results and remaining the subject controversial. in this study, we investigated differences of the semen parameters and intracytoplasmic sperm injection (icsi) outcome according to sperm dna fragme...

STUDY OBJECTIVE To evaluate the effect of experimental sleep fragmentation (sleep interruption; SI) on complex learning in an intradimensional-extradimensional (ID/ED) set-shifting task in rats. DESIGN A sleep fragmentation paradigm of intermittent forced locomotion was validated in adult rats by examining electrographic effects. Discrimination task performances were assessed in rats followin...

A method for the identification of bacterial colonies based on their content of specific genes is presented. This method does not depend on DNA separation or DNA amplification. Bacillus cereus carrying one of the genes (hblC) coding for the enterotoxin hemolysin was identified with this method. It is based on target DNA hybridization to a capturing probe immobilized on magnetic beads, followed ...

background: although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions. objective: this study was designed to investigate the effects of ginger (zingiber officinale) on sperm dna fragmentation (sdf) in infertile men. materials and methods: this randomized double-blind, placebo-controlle...

We have measured the differential cross sections for the production of π, K, K, K(892), φ(1020), p and Λ in hadronic Z decays and in subsets of flavor-tagged Z → light quark (uū, dd̄, or ss̄) , Z → cc̄ and Z → bb̄ events. Charged hadrons were identified with the SLD Cherenkov ring imaging detector. The vertex detector was employed to select flavor enriched samples and the polarized electron beam fr...
