BACKGROUND The hepatic outcome of hepatitis B surface antigen (HBsAg) positive patients undergoing chemotherapy after withdrawal of pre-emptive lamivudine is unknown. AIMS To examine the occurrence of hepatitis B virus (HBV) reactivation after withdrawal of pre-emptive lamivudine. METHODS Pre-emptive lamivudine was started one week before initiation of chemotherapy in 46 consecutive HBsAg p...

Cases of ATR harmony are numerous and widely documented in the literature, whereas languages in which RTR is harmonically active (e.g. Wolof) have received a good deal less attention. A description based on the bivalent feature [±ATR] is capable of representing both harmony types, but fails to encode naturally the clear difference in typological markedness separating the two. On the other hand,...

Study Selection Studies were selected if they were randomised controlled trials (RCTs) that compared the outcome when analgesics were given before surgical incision with the outcome when the same medication was given after surgical incision. Studies that compared pre-emptive analgesia with no analgesia or that compared pre-emptive analgesia with pre-emptive analgesia plus analgesia given after ...

This paper introduces schedulability analysis for global fixed priority scheduling with deferred pre-emption (gFPDS) for homogeneous multiprocessor systems. gFPDS is a superset of global fixed priority pre-emptive scheduling (gFPPS) and global fixed priority non-pre-emptive scheduling (gFPNS). We show how schedulability can be improved via appropriate choice of priority assignment and final non...

BACKGROUND Experimental studies suggest pre-emptive administration of analgesics is effective but clinical evidence is less convincing. METHODS Forty-one patients undergoing abdominal hysterectomy were allocated randomly in a double-blind fashion to receive sufentanil 50 micrograms via a lumbar epidural catheter before or at the end of surgery. RESULTS Sufentanil consumption from a patient-...

Abstract This article focuses on the application of autonomous weapons (AWs) in defensive systems and, consequently, assesses conditions legality employing such from perspective right to self-defence. How far may humans exert control over AWs? Are there any legal constraints using AWs for purpose self-defence? does their use fit into traditional criteria The claims that are no grounds exclude a...

The usage of the radio spectrum for wireless communication is considered to be inefficient. Therefore, through cognitive radio, unlicensed users can occupy idle spectrum bands without interference with the primary user. Generally, when the arrival rate of licensed users is high, secondary users may starve. In this paper, we propose two models to improve the average total waiting time for the se...
