Background: Morbid obesity is associated with a some of significant comorbidities. Early and uneventful postoperative recovery of obese patients remains a challenge for anesthesiologists. It seems Bispecteral Index (BIS) monitoring may reduce drug usage and hasten recovery time in inhalation anesthesia. The aim of this study was to investigate the effect of BIS monitoring on intraoperative isof...
polyvinyl butyral (pvb) was synthesized by condensation reaction of polyvinyl alcohol (pva) with butanal in aqueous medium containing an effective emulsifier and an inorganic acid as catalyst. the product was characterized by, ir, tg and dtg techniques. percentage of vinyl alcohol groups in the pvb was determined by a chemical method according to a standard method. some clear and soft film samp...
بسیاری از فیلسوفان پیش از ملاصدرا وجود را اعتباری و معقول دوم میدانستند؛ به این معنی که دارای مابإزای عینی و بالذات نیست. اگر در نظریة اصالت وجود، وجود عین تحقق و خارجی بودن است، مفهوم وجود ضرورتاً دارای مصداق یا مابإزای عینی خواهد بود و به همین دلیل نمیتواند اعتباری و معقول دوم به معنای پیش گفته باشد. در واقع بین اصیل بودن، منشأ آثار بودن و خارجی بودن وجود و نحوة دلالت مفهوم وجود به امور که م...

Introduction: Elderly is considered from 60-65 years old, and 35% of all surgeries related to this age group. Surgical complications in these patients have a high incidence and to reduce these complications Bispectral (BIS) monitoring during the anesthesia can be used. This study was designed to investigate whether BIS monitoring improves clinical anesthetic delivery, recovery profiles in elder...
In this article, we report on the synthesis of acyclic bis(monoalkylamino)maleonitriles and intended macrocyclic bis(dialkylamino)maleonitriles to get fluorescent probes for cations. During our efforts synthesize bis(dialkylamino)maleonitriles, were only able isolate bis(dialkylamino)-fumaronitriles. The is challenging, due fact that bis-(dialkylamino)fumaronitriles are thermodynamically more s...
