background: because nerve stimulators are not always available for brachial plexus block, fmding the right injection spot for nerve blocks is important. in this study we used physical examination to determine the appropriate spot for injection. methods: all patients who were candidates for upper extremity surgery and were either in class asa i or asa ii, were selected. paresthesia was elicited ...

objectives thereby the prevalence, distribution characteristics and correlative factors of oa in mongolian middle-aged and senior residents in the inner mongolia autonomous region were investigated in this study. materials and methods rural and urban residents in hohhot, baotou and erdos were selected using stratified, multi-stage and cluster random sampling. 2000 residents aging over 45 filled...

introduction: assessment tools of academic achievement in the field of surgery have always been received considerable attention. the issue that has received less attention is that which one of these methods has higher efficiency to cover appropriately educational objectives in surgical groups. this survey aimed to evaluate the results of three examinations (including osce, in-group educational ...

the aim of this study was to compare the level of agreement between four operators with different levels of experience for two methods of detecting secondary enamel and dentin carious lesions in composite restored teeth.sixty teeth of 40 patients with with secondary carious lesions in the composite resin were selected. the teeth were examined by two methods; visual inspection and a laser fluore...

Abstract Escherichia coli has been used as a host to construct the cell factory for biobased production of chemicals from renewable feedstocks. Because galactose is found in marine biomass major component, strategy utilization E. gained more attention. Although and glucose co-fermentation reported using engineered strain, few reports have covered fermentation supplemented with sole carbon sourc...

Timing Closure in presence of long global wire interconnects is one of the main current issues in System-onChip design. One proposed solution to the Timing Closure problem is Latency-Insensitive Design (LID) [5,7]. It was noticed in [7] that, in many cases, the dynamically scheduled synchronisations introduced by latency-insensitive protocols could be computed off-line as a static periodic sche...

In the paper entitled "The Fundamental Free Mode of the Earth's Inner Core," by Louis B. Slichter, which appeared in the February issue of this volume, the author wishes to make the following corrections: On page 186, 4th line from the bottom, the stated value of the gravitational response associated with the suggested oscillation is too high; read "0.1" (not "0.64") IM gals. The associated amp...

This paper introduces a new methodology to solve the interfacing problem in Globally Asynchronous Locally Synchronous (GALS) design approaches. We present a generic high-speed and delay-insensitive connector based on asynchronous four state logic (FSL). The advantages of this approach are following: First, it provides flexibility in the time domain since the data transfer is based on local hand...
