{Large scale clustered continuous media (CM) servers deployed in applications like video-on-demand have high availability requirements. In the event of server failure, streams from the failed servers must be reassigned to healthy servers with minimum service disruption. Such servers may also suuer from periods of transient overload resulting from a high degree of customer interactivity. For exa...

In this study, we investigated a signalling load control mechanism for SIP server networks and developed a corresponding queuing model. The so-called hop-by-hop overload control, known from recent IETF drafts and RFCs, was considered and a similar buffer overload control scheme which was developed for the SS7 signalling link in ITU-T Recommendation Q.704, was proposed. The mechanism is based on...

Iron overload is an adverse prognostic factor for patients undergoing hematopoietic stem cell transplantation (HSCT). In the HSCT setting, pretransplant and early posttransplant ferritin and transferrin saturation were found to be highly elevated due to high transfusion requirements. In addition to that, post-HSCT iron overload was shown to be related to infections, hepatic sinusoidal obstructi...

There is increasing evidence that fluid overload and acute kidney injury (AKI) are associated but the exact cause-effect relationship remains unclear. Wang and colleagues analysed patients admitted to 30 intensive care units in China and found that fluid accumulation was independently associated with an increased risk of AKI and mortality. This commentary focuses on the close pathophysiological...

Study examines the sources and origins of information overload, its effects on knowledge workers, and its overall implications for business companies. The main argument presented in this study is that information overload is not a singular issue but that it arises out of a combination of excessive amount of both sought information and supplied information (i.e. interruptions and distractions). ...

PURPOSE OF REVIEW This review highlights the recent evidence describing the outcomes associated with fluid overload in critically ill patients and provides an overview of fluid management strategies aimed at preventing fluid overload during the resuscitation of patients with shock. RECENT FINDINGS Fluid overload is a common complication of fluid resuscitation and is associated with increased ...

Work life takes up an important place in human life, and an employee faces many stimuli from internal and external environments and is affected by them in a positive or negative way. Aim: was to investigate relationship among nurses role overload, burnout and managerial coping strategies at Intensive Care Units in Assiut University Hospital. Design: A correlational descriptive design was used. ...

Despite the voluminous evidence in support of the paradoxical finding that providing individuals with more options can be detrimental to choice, the question of whether and when large assortments impede choice remains open. Even though extant research has identified a variety of antecedents and consequences of choice overload, the findings of the individual studies fail to come together into a ...

Iron-mediated organ damage is common in patients with iron overload diseases, namely, hereditary hemochromatosis. Massive iron deposition in parenchymal organs, particularly in the liver, causes organ dysfunction, fibrosis, cirrhosis, and also hepatocellular carcinoma. To obtain deeper insight into the poorly understood and complex cellular response to iron overload and consequent oxidative str...

BACKGROUND Myocardial siderosis is the most common cause of death in patients with beta thalassemia major(TM). This study aimed at investigating the occurrence, prevalence and severity of cardiac iron overload in a young Chinese population with beta TM. METHODS AND RESULTS We analyzed T2* cardiac magnetic resonance (CMR), left ventricular ejection fraction (LVEF) and serum ferritin (SF) in 20...
