Excess di(tert-butyl)silylene (DTBS) bis(trifluoromethanesulfonate) formed bis-DTBS derivatives with the four aldopentoses (arabinose, lyxose, ribose and xylose). The structure of the bis-chelates was affected by the bulk of the DTBS groups and the requirement of flat silacycles in the case of five-membered chelate rings. These restrictions resulted in unusual cyclic bis-chelates for ribofurano...
BACKGROUND Anesthetic administration is increasingly guided by electroencephalography (EEG)-based monitoring, such as the bispectral index (BIS). However, during cardiopulmonary bypass (CPB), factors other than the administered hypnotic agents may influence EEG signals, and their effects on BIS values are unknown. METHODS This report is a secondary analysis of data from a prospective, control...
BACKGROUND Accuracy of consciousness level assessment is very important. It may determine and influence further clinical decisions, thus influences patients' outcomes. The widest method in determining the level of awareness is the Glasgow Coma Scale (GCS). Despite its common use, GCS scores obtained by one clinician may differ from others depending on their interpretations and past experience. ...
2, 2-Bis [4- (2-hydroxy-3-methacryloyloxypropoxy) phenyl] propane (bis-GMA) is widely used in dentistry as a monomer of composite resin system and their bonding agents. Since bis-GMA is not purified, its isomers and some chemicals such as residual initiator remain in the commercial product. Bis-GMA and iso-bis-GMA were separated from bis-GMA monomer by HPLC. NMR spectra of both monomers were re...
A general method for the preparation of bis-ureas from bis(o-nitrophenyl) carbonate has been developed. Directional urea synthesis is achieved by sequential amine addition to bis(o-nitrophenyl) carbonate in two steps: in the first step bis(o-nitrophenyl) carbonate is reacted with benzylamine to form benzyl-o-nitrophenyl carbamate; in the second step the carbamate is reacted with a variety of di...
Differences between different style-depressed mothers, intrusive and withdrawn, were examined by the use of the Behavioral Inhibition and Activation Scales (BIS/BAS) and EEG activity from the mid-frontal and parietal regions. Analyses revealed that withdrawn mothers had left frontal EEG hypoactivation, higher Behavior Inhibition (BIS), and lower Behavior Activation (BAS) scores than the intrusi...
BACKGROUND In general, measuring the level of consciousness in neurological patients is important. To assess the patient's mental status, the Glasgow Coma Scale (GCS) and the level of consciousness (drowsiness, stupor, and coma) have been used in clinical situations. The aim of the present study was to identify the correlation between bispectral index (BIS) and level of consciousness in brain i...
در سیستمهای مخابرات نوری که در چند سال اخیر با پیشرفتهای فراوانی همراه بوده است. با بکارگیری گسترده زیرساخت فیبر نوری و توسعه سیستمهای مربوط به آنها و گستردگی نیازهای کاربران، شبکه های دسترسی (access networks) و از طرفی جوابدهی به نیازها، توسعه فراوانی یافته است. در این راستا با افزایش کاربران اینترنتی و نیاز به سرویسهای جدید مانند تلویزیون با کیفیت بالا (hdtv) و... بحث بهینه سازی شبکه های موجو...
While extant business intelligence systems (BIS) adoption research focused mainly on adoption of BIS in large-sized organizations, our understanding about the adoption determinants and the process within small and medium enterprises (SME) is still limited. The aim of our research is to identify SME-specific determinants of BIS adoption at firm level that will guide the development and testing o...
The chiral carbene bis[bis(R-1-phenylethyl)amino]cyclopropenylidene 2 and its dicarbene-silver complex [Ag(2)2]BF4 (3) have been isolated in good yields from the reactions of bis[bis(R-1-phenylethyl)amino]cyclopropenylium tetrafluoroborate (1)BF4 with potassium bis(trimethylsilyl)amide or with Ag2O, respectively; the molecular structures of (1)ClO4, 2 and 3 have been determined by X-ray diffrac...
