Acute ventricular loading by volume inflation reversibly slows epicardial electrical conduction, but the underlying mechanism remains unclear. This study investigated the potential contributions of stretch-activated currents, alterations in resting membrane potential, or changes in intercellular resistance and membrane capacitance. Conduction velocity was assessed using optical mapping of isola...

We review the first experiment on dynamic transport in a phase-coherent quantum conductor. In our discussion, we highlight the use of time-dependent transport as a means of gaining insight into charge relaxation on a mesoscopic scale. For this purpose, we studied the ac conductance of a model quantum conductor, i.e. the quantum RC circuit. Prior to our experimental work, Büttiker et al (1993 Ph...

The customer relationship management (CRM) system has been touted as a primary tool for supporting frontline employees’ personalized services tasks. Although a number of studies have highlighted the critical role of CRM systems in organizational performance, the link between CRM systems and individual work performance is still under investigation. In order to fill this research gap, the current...

BACKGROUND Clinical risk management (CRM) plays a crucial role in enabling hospitals to identify, contain, and manage risks related to patient safety. So far, no instruments are available to measure and monitor the level of implementation of CRM. Therefore, our objective was to develop an instrument for assessing CRM in hospitals. METHODS The instrument was developed based on a literature rev...

For an organisation to undertake a Customer Relationship Management (CRM) implementation program it needs to consider a multitude of issues. Some authors have hinted at viewing CRM within a wider perspective. The aim of this paper is to discuss the domain of CRM from an organisation's point of view. However, CRM needs to be identified as the whole organisation, including its internal and extern...

BACKGROUND Creatine monohydrate (CrM) has been consistently reported to increase muscle creatine content and improve high-intensity exercise capacity. However, a number of different forms of creatine have been purported to be more efficacious than CrM. The purpose of this study was to determine if a buffered creatine monohydrate (KA) that has been purported to promote greater creatine retention...

an improved model of mud dispersion has been introduced in this work. the advantages of this model consist of a new analytical correlation for dispersivity by using resistivity log data and using a new aspect of capacitance dispersion model. mathematical formulations were expressed, solved by numerical model taking advantage of actual log and formation data. achieved results yielded reasonable ...

The concept of customer relationship management (CRM) resonates with managers in today's competitive economy. Yet recent articles in the business press have described CRM implementation failures, and consequent company reluctance to invest in CRM. The potential for substantially improved customer relationship management, coupled with the high uncertainty surrounding failed implementation effort...
