BACKGROUND Antibiotic resistance is caused partly by excessive antibiotic prescribing, yet little is known about prescribers' views on this problem. METHODS We surveyed 490 internal medicine physicians at 4 Chicago-area hospitals to assess their attitudes about the importance of antibiotic resistance, knowledge of its prevalence, self-reported experience with antibiotic resistance, beliefs ab...

STATEMENT OF PROBLEM Although the implant-abutment connection may prevent crestal bone loss around dental implants, its failure often leads to treatment failure. Microgap and micromovement of the implant-abutment connection could be causes of bone resorption around dental implant neck. PURPOSE The purpose of this study was to compare torque resistance and microgaps between a new cone and inde...

This study tests, the hypothesis that asymptomatic patients with hemodynamically significant internal carotid artery stenosis have a lower ipsilateral collateral cerebral vascular resistance and hence greater blood flow than their symptomatic cohorts. We measured internal carotid artery blood flow and cerebral perfusion pressures intraoperatively prior to and after carotid endarterectomy in 35 ...

[Purpose] The aim of this study was to present an individualized resistance training method to enable exercise while maintaining an exercise load that is set according to an individual's joint angle-torque using a haptic-based resistance training machine. [Methods] Five participants (machine group) performed individualized shoulder internal and external rotation training with a haptic resistanc...

Department of Mechanical Engineering, The Hong Kong Polytechnic University Hung Home, Kowloon, Hong Kong, SAR of China Email address: [email protected]. Abstract This paper examines the influence of the internal resistance of a Helmholtz resonator on the noise control in a small enclosure. The absorptive process mainly occurring within the neck of a Helmholtz resonator provides the resonator w...

Estimating the state of charge is important for any battery operated device. In case of automobile batteries, which are designed to deliver large power, many methods such as open circuit voltage based, ampere hour counting based, impedance based are used for calculating the state of charge. Internal resistance of a battery at a particular temperature directly gives the information about the sta...

literature is the reflection of a poet's mind and feelings affected by the world around him. the poet experiences and feels the incidents and expresses them in a language so as to make the reader share those feelings with him. a great part of persian literature is devoted to poets' resistance against attacks on national, human and cultural values. this study aims at examining tahereh ...

Abstract – This paper presents the cross-coupled MOS resistor circuits. The circuits consist of two internal pairs of NMOS and PMOS transistors, and their critical width and length parameters regulate the drain current, transconductance, and output drain resistance. Consequently it determines the output resistance of the circuits. The cross-coupled MOS resistor circuits can be used in multiplic...
