background and aim: iron overload in patients with thalassemia major is one of the most important complications of this disease and its cardiac complications are the most important causes of death in these patients.mri t2 is the perfect device to assess the amount of iron deposited in the heart of thalassemia patients, but it causes waste of time and also is an expensive diagnostic method. tiss...

Purpose With the shift to an information-based society and de-centralisation of information, information overload has attracted a growing interest in computer science research communities. However, there is no clear understanding meaning term, while have been many proposed definitions, consensus. The goal this work was define concept “information overload”. In order do so, analysis using Rodger...

Overload occurs in Session Initiation Protocol (SIP) networks when SIP servers have insufficient resources to handle all the SIP messages they receive. Even though the SIP protocol provides a limited overload control mechanism through its 503 (Service Unavailable) response code, SIP servers are still vulnerable to overload. This document defines the behavior of SIP servers involved in overload ...

The usefulness of thallium-201 myocardial imaging in assessing right ventricular (RV) overloading was evaluated and compared with the electrocardiographic and hemodynamic measurements. Multiple unprocessed photoscans were obtained using a gamma camera in 47 patients who had chronic RV overload, including 28 subjects with pressure overload, 14 with volume overload and five with pressure and volu...

www.aafp.org/afp AMERICAN FAMILY PHYSICIAN 853 Most physicians diagnose only a few cases of hereditary hemochromatosis in their practice because they do not routinely test for iron overload and because many patients with the disorder have no manifestations. It is estimated that the typical primary care physician encounters one patient with hereditary hemochromatosis every two weeks. Iron overlo...

Abstract—The Session Initiation Protocol (SIP) retransmission mechanism is designed to maintain reliable transmission over lossy or faulty network conditions. However, the retransmission can amplify the traffic overload faced by the SIP servers. In this paper, by modeling the interaction between an overloaded downstream server and its upstream server as a feedback control system, we propose two...

Introduction. We explore predictors of information overload among cancer information seekers who reported having suffered from information overload. These persons were characterized by socio-demographic characteristics, health status, health information and communication environment and behavioural, cognitive, and affective cancer information seeking. Method. A secondary analysis was performed ...

We study numerically and analytically the coarsening of stripe phases in two spatial dimensions, and show that transient configurations do not achieve long ranged orientational order but rather evolve into glassy configurations with very slow dynamics. In the absence of thermal fluctuations, defects such as grain boundaries become pinned in an effective periodic potential that is induced by the...

As a major part of farming sustainability, the issues of grain production and its quality improvement have been important in many countries. This paper aims to address these issues in China. Based on the data from the main production provinces and by applying the stochastic frontier analysis methodology, we find that the improvement of transportation and the use of agricultural machinery have b...
