We discuss the notion of noncommutative point derivations for operator algebras. We look at the noncommutative point derivations for the quiver algebras, A(Cn) where Cn is the directed graph with n-vertices and n-edges forming a cycle. For the algebras Mn ⊗ A(D) and A(Cn) we classify when non-trivial point derivations can occur. We use the point derivations to show that every derivation on A(Cn...

abstract background: the fear of aspiration of gastric contents and its life‑threatening disadvantages in patients have encouraged many medical practitioners to follow conservative policies for clear fluid/liquid and solid intake from midnight to the time of surgery. these policies have been pursued more severely in case of pregnant women, leading the physicians to follow “nil per os” policy. t...

objective: the purpose of this study was to investigate the incidence, type, location, and risk factors of accidental fetal lacerations during caesarean delivery. material and methods: total deliveries, caesarean deliveries, and neonatal records for documented accidental fetal lacerations were reviewed retrospectively in four university hospital. thegestational age, the presenting part of the f...

background: postoperative pain control after cesarean section (c/s) is important because inadequate postoperative pain control can result in a prolonged hospital stay. in this study, we compared postoperative somatic wound pain control between patients receiving tramadol and bupivacaine, infiltrated at the wound site. methods: in this randomized clinical trial, 98 patients, eligible for electiv...

this paper reported on a genre-driven comparative study, which aimed to identify the generic moves in the conclusion sections of twenty research articles in the field of sociology written in the two codes of persian and english. to meet this purpose, the researchers employed moritz, meurer, and dellagnelo's model, which was set within the swalesian framework of genre analysis. the analysis...

conclusions higher ods score in females who had c/s showed that c/s could not protect the pelvic organ from pregnancy and delivery trauma. it seems that episiotomy has a protective effect during vd; it can reduce the severity of trauma in pelvic organs during childbearing. results in 30 consecutive females undergoing starr for the treatment of ods, who enrolled in this prospective study, 19 (63...

the quality of subarachnoid block can be improved by adding opioids to the local anesthetics. we compared the analgesic effects of different doses of intrathecal sufentanil added to lidocaine %5 for elective cesarean section. this study was a prospective, randomized, double-blind, controlled trial. 90 pregnant women with asa class i-ii, scheduled for elective cesarean section under spinal anest...

background: shivering is one of the common problems in spinal anesthesia. the objective of the present study was to evaluate the effect of intrathecal fentanyl (25 μg) on incidence and severity of intraoperative and postoperative shivering. methods: a double-blind randomized controlled study was conducted in eighty healthy women (asa physical status i) scheduled for elective cesarean section un...
