The increasing number of Internet users and innovative new services such as e-commerce are placing new demands on Internet servers, for example web servers. It is becoming essential for Internet servers to be highly available, have fast response times, and provide continuous service during overload at least to preferred customers. It is necessary, therefore, to protect Internet servers from ove...

Antagonists of the mineralocorticoid receptor improve morbidity and mortality in patients with severe heart failure. However, the cell types involved in these beneficial effects are only partially known. The aim of this work was to evaluate whether genetic deletion of mineralocorticoid receptors in mouse cardiomyocytes or fibroblasts in vivo is cardioprotective after chronic left ventricular pr...

Telecommunication switches implement overload controls to maintain call throughput and delay at acceptable levels during periods of high load. Existing work has mostly focused on controls under sustained overload–they do not meet the demands of modern telecommunication systems where the increased number of services and mobile subscribers often creates fast changing hot spots. We introduce new a...

iron overload is known to occur in the west european and american population due to the consumption of iron-rich diets. on the other hand, genetic disorders leading to iron overload are also known. iron overload leads to increased peroxidation and disruptive disintegration of lipid-rich membranes, and predisposes humans for an enhanced risk of cancer induction. in experimental animals iron over...

In this paper a mixed-model assembly-line sequencing problem with the goal of minimizing work overload is addressed. We consider time windows in work stations of the assembly line (closed stations). Different versions of a product to be assembled in the line (e.g. automotive industry), which require different processing time according to the work required in each work station are considered. In...

The amount of email people have to deal with is overwhelming. People tend to work extra hours in order to keep up with their email, and some are even getting ill because of all the stress this overload generates. This paper describes the causes and symptoms of email overload, the strategies people use to deal with it and possible solutions towards the problem. These are given with the help of a...

Background Myocardial tissue characterization with T2-weighted imaging is an established technique for evaluating the presence of myocardial edema or iron overload (Kellman, P. MRM 2007, Anderson, LJ. EHJ 2001). More recently, both T2-mapping and apparent diffusion coefficient (ADC) mapping have emerged as quantitative techniques for characterizing edema (or iron overload) and water mobility. T...

This study is conducted to investigate the effect of job stress on job performance. A random sampling technique is used to collect primary data of 120 employees of four telecommunication companies of Mongolia i.e. Mobicom, Unitel, Skytel and G-mobile. A well-structured questionnaire is utilized to collect relevant data; descriptive and logistic analysis is used to estimate and describe the find...

The concept of work exhaustion (or job burnout) from the management and psychology research literature is examined in the context of technology professionals. Data were collected from 270 IT professionals and managers in various industries across the United States. Through structural equation modeling, work exhaustion was shown to partially mediate the effects of workplace factors on turnover i...
