Ablation behaviors of laminated carbon fiber reinforced plastics (CFRP) subjected to intense continuous wave laser in the supersonic wind tunnel are investigated experimentally. Comparable ablation tests other environments, i.e., static air, nitrogen and open airflow, also carried out. Laser rate is significantly larger than those particular, at least twice that an tangential airflow condition....
Members of the DAZ (Deleted in AZoospermia) gene family are important players in the process of gametogenesis and their dysregulation accounts for 10% of human male infertility. Boule, the ancestor of the family, is mainly involved in male meiosis in most organisms. With the exception of Drosophila and C. elegans, nothing is known on the function of boule in non-vertebrate animals. In the prese...
Defects in human germ cell development are common and yet little is known of genes required for germ cell development in men and women. The pathways that develop germ cells appear to be conserved broadly, at least in outline, in organisms as diverse as flies and humans beginning with allocation of cells to the germ cell lineage, migration of these cells to the fetal gonad, mitotic proliferation...
This paper presents the results of a Spitzer IRAC 3−8 μm photometric search for warm dust orbiting 17 nearby, metal-rich white dwarfs, 15 of which apparently have hydrogen dominated atmospheres (type DAZ). G166-58, G29-38, and GD 362 manifest excess emission in their IRAC fluxes and the latter two are known to harbor dust grains warm enough to radiate detectable emission at near-infrared wavele...
زمینه و هدف: انجام صحیح و کامل روند اسپرماتوژنز مستلزم بیان تعداد بسیار زیادی ژن به صورت همزمان و یا با توالی خاص خود می باشد؛ به طوری که توقف یا اختلال در بیان هر یک از آنها ممکن است منجر به توقف یا اختلال در روند اسپرماتوژنز گردد. شناسایی این قبیل ژنها و ارزیابی عملکرد آنها اطلاعات ارزشمندی درباره نقش این ژنها در اسپرم بالغ، روند اسپرماتوژنز و نیز عملکرد بعدی آنها در فرآیند لقاح و تکوین جنین ...
