Anti-Stokes scattering and Stokes scattering in stimulated Brillouin scattering (SBS) cascades have been researched using the Vlasov–Maxwell simulation. In high-intensity laser–plasma interactions, stimulated anti-Stokes Brillouin scattering (SABS) will occur after second stage SBS rescattering. The mechanism of SABS has been put forward to explain this phenomenon. In the early phase of SBS evo...

کاربرد پلیمر برای اصلاح خواص قیرهای مورد استفاده در روسازی راه در دهه های اخیر روبه افزایش است، بطوریکه متصدیان راهسازی با بکارگیری آنها و افزایش عمر راه ها، باعث افزایش عبور ترافیک (عمر بهره برداری) راه ها می شوند. بیشترین پلیمرهایی که برای اصلاح خواص قیرها کاربرد دارند، معمولا اصلاح کننده های پلیمری شامل: استایرن-بوتادین-استایرن (sbs) وپلیمرهای مشابه مانند: استایرن- بوتادین- رابر (sbr) ، اتی...

یکی از عواملی که موجب بروز ترک ها در سطح روسازی می شود، پیرشدگی قیر است. پیرشدگی قیر بر اثر تبخیر برخی از ترکیبات فرار قیر در مرحله تولید مخلوط آسفالتی و اکسید شدن برخی از ترکیبات قیر به وجود می آید. پیرشدگی موجب سخت تر شدن و شکننده شدن قیر می شود که منجر به تشکیل و گسترش ترکها در سطح روسازی و در نهایت تخریب روسازی می شود. در این پژوهش خصوصیات شیمیایی و رئولوژیک قیر اصلاح شده با پلیمر استایرن...

BACKGROUND Short bowel syndrome (SBS) is a severe malabsorption caused by bowel loss. Congenital intestinal anomalies (CIA) detectable by prenatal ultrasound as jejunoileal atresia, meconium peritonitis, complicated meconium ileus, and fetal volvulus can be responsible for SBS. AIMS This study aims to investigate either frequency of SBS or the morbidity in CIA population during the first admi...

PURPOSE The disease concept of sick building syndrome (SBS) is still unclear. Ocular mucous membrane irritation is one of the major symptoms of SBS. However, the immunological aspects of the ocular complications of SBS are not yet clarified. The clinical and allergological aspects of SBS cases with ocular disorders with special reference to allergic conjunctival diseases (ACD) were analyzed, es...

Sphingoid bases (SBs) as bioactive sphingolipids, have been implicated in aging in yeast. However, we know neither how SBs are regulated during yeast aging nor how they, in turn, regulate it. Herein, we demonstrate that the yeast alkaline ceramidases (YPC1 and YDC1) and SB kinases (LCB4 and LCB5) cooperate in regulating SBs during the aging process and that SBs shortens chronological life span ...

Liver disease is a major source of morbidity and mortality in children with short bowel syndrome (SBS). SBS-associated microbial dysbiosis has recently been implicated in the development of SBS-associated liver disease (SBS-ALD), however the pathological implications of this association have not been explored. In this study high-throughput sequencing of colonic content from the well-validated p...

The aim of the current study is to examine the improving effect of Sasa borealis stem (SBS) extract extracts on high-fat diet (HFD)-induced hepatic steatosis in rats. To determine the hepatoprotective effect of SBS, we fed rats a normal regular diet (ND), HFD, and HFD supplemented with 150 mg/kg body weight (BW) SBS extracts for five weeks. We found that the body weight and liver weight of rats...

We derive formal selection rules for Stimulated Brillouin Scattering (SBS) in structured waveguides. Using a group-theoretical approach, we show how the waveguide symmetry determines which optical and acoustic modes interact for both forward and backward SBS. We present a general framework for determining this interaction and give important examples for SBS in waveguides with rectangular, trian...

PURPOSE The main objective of this study was to develop a novel aerosolized liposome formulation for pulmonary delivery of anti-asthmatic medication and to explore the relationship between the bioavailability and anti-asthmatic efficacy of such a formulation. Asthma treatment usually requires frequent administration of medication for sustained bronchodilating response. Liposomes are known for t...
