Chlorinated organic compounds resu l t from ch lor inat ion treatment of wastewater. The discharges, containing these compounds, in to the aquatic environment have resulted in widespread concern. Invest igat ions have been conducted on the ef fects of these chloro-organics on aquatic l i f e . Most of the studies, however, have been conducted on zooplankton or higher organisms. Only l imi ted i...

STUDY DESIGN A multicenter, retrospective analysis of cervical epidurograms. OBJECTIVES To determine the effectiveness of the loss of resistance (LOR) technique in identifying the cervical epidural space. To delineate the pattern of epidural contrast spread during cervical epidural steroid injections. BACKGROUND Previous studies have shown that if performed without fluoroscopy, the LOR tech...

BACKGROUND Cerebral state index (CSI) has recently been introduced as an intra-operative monitor of anaesthetic depth. We compared the performance of the CSI to the bispectral index (BIS) in measuring depth of anaesthesia during target-controlled infusion (TCI) of propofol. METHODS Twenty Chinese patients undergoing general anaesthesia were recruited. CSI and BIS, and predicted effect-site co...

Forschungszentrum Jülich GmbH, Jülich, Germany Fast PET image reconstruction algorithms usually use a Line-of-Response (LOR) preprocessing step where the detected raw LOR data are interpolated either to evenly spaced sinogram projection bins or alternatively to a generic projection space as for example proposed by the PET Reconstruction Software Toolkit (PRESTO) [1]. In this way, speed-optimise...

BACKGROUND Paravertebral regional anaesthesia is used to treat pain after several surgical procedures. This study aimed to improve on our first published ultrasound-guided approach to the paravertebral space (PVS) and to investigate a possible discrepancy between the needle, catheter, and contrast dye position. METHODS In 10 cadavers, we conducted 26 ultrasound-guided paravertebral approaches...

BACKGROUND Epidrum® is a recently developed, air operated, loss of resistance (LOR) device for identifying the epidural space. We investigated the usefulness of Epidrum® by comparing it with the conventional LOR technique for identifying the epidural space. METHODS One hundred eight American Society of Anesthesiologists (ASA) physical status I or II patients between the ages of 17 and 68 year...

We consider a two-class M " A2 IMI'11 preemptive priority queue in which there are two essential on-line decisions that have to be taken. The first is the decision to either accept or reject new type-lor type-2 jobs. The second is the decision to abort jobs, i.e., to remove any type-lor type-2 jobs from the system. We show that there exist optimal threshold policies for these two types of decis...
