Hava araçları tasarımında kablo ve ekipman ağırlığının azaltılması önemli bir gereksinim kriteridir. Gelişen teknoloji ihtiyaçlar doğrultusunda hava sistem mimarisi federe yapıdan modüler yapıya evirilerek ağırlığına çözüm bulmasına karşın etkin getirememiştir. Bu maksatla verilerin ihtiyaç duyulduğu yerde işlemlerin gerçekleştirilmesine dayalı fakat kablaj ağırlığı getirmeyecek yapının tesisin...
در مکتب نگارگری هرات (قرن نهم هـ. ق.) سه شاهنامه معتبر با حمایت امیران و شاهزادگان تیموری کتابت و نگارگری شد. این سه شاهنامه عبارت بودند از: شاهنامه بایسنقری (833 هـ. ق.) شاهنامه محمد جوکی (848 هـ. ق.) و شاهنامه ابراهیم سلطان (833 هـ. ق.). شاهنامه محمد جوکی که همزمان با دیگر شاهنامههای دوره تیموری تصویر شد، به حمایت و سفارش محمد جوکی (تولد 806 هـ. ق. وفات 848 هـ. ق.) از شاهزادگان تیموری و پنج...
HIF-1 is the master regulator of cellular hypoxia response; the oxygen sensitive HIF-1α subunit transactivates its own expression in hypoxia via a hypoxia response element (HRE) in the promoter of the HIF-1α gene. This transactivation loop significantly contributes to the build up of HIF-1α at the onset of hypoxia, with the binding of HIF-1 to the HIF-1α promoter being dependent on the epigenet...
BACKGROUND/AIMS Cytomegalovirus (CMV) surveillance and preemptive therapy is a widely-used strategy for preventing CMV disease in transplant recipients. However, there are limited data on the incidence and patterns of CMV disease during the preemptive period. Thus, we investigated the incidence and pattern of tissue-invasive CMV disease in CMV seropositive kidney transplantation (KT) and hemato...
MicroRNAs (miRNAs) are small non-coding RNA species that have been shown to have roles in multiple processes that occur in higher eukaryotes. They act by binding to specific sequences in the 3' untranslated region of their target genes and causing the transcripts to be degraded by the RNA-induced silencing complex (RISC). MicroRNAs have previously been reported to demonstrate altered expression...
Femto-second transient absorption spectroscopy has been applied to investigate the back-electron transfer process after the photo-excitation of p-nitroaniline (PNA) in water from ambient to supercritical condition. After PNA was photo-excited at 400 nm, the bleach recovery signal was observed due to the back-electron transfer from the excited state to the ground state within about 1 ps. In the ...
In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...
