Background This study aimed to understand the perceptions that Spanish teachers of different educational levels have about functions attributed them, overload administrative tasks they face daily, and external consideration their professional profile has raised. A generational perspective was adopted in this study, taking into stages: Early Childhood, Primary, Secondary Education. Methods descr...

Abstract Background: Iron overload is a clinical consequence of repeated blood transfusions and causes significant organ damage, morbidity, and mortality in the absence of proper treatment. The primary targets of Iron chelators used for treating transfusional Iron overload are the prevention of Iron ingress into tissues and its intracellular scavenging. The present study was aimed at elucid...

The issue of information overload in group decision making settings has not received sufficient attention in the past. In particular, information processing and information complexity have not been addressed in the context of GSS research. This paper discusses a study that examined whether information overload occurs in group decision making settings, using a combination of measures for informa...

Studying information di usion through social networks has become an active research topic with important implications in viral marketing applications. One of the fundamental algorithmic problems related to viral marketing is the In uence Maximization (IM) problem: given an social network, which set of nodes should be considered by the viral marketer as the initial targets, in order to maximize ...

OBJECTIVE Right ventricular dysfunction is a poorly understood but persistent clinical problem. This study was undertaken to evaluate ventricular performance and beta-adrenergic receptor signaling in a tricuspid regurgitation model of right ventricular overload. METHODS Seventeen dogs were chronically instrumented with epicardial dimension transducers. By means of the shell-subtraction model,...

The rapid development of services provided on SIP networks not only define the necessity of creating new equipment and standards but also requires the development of new methods and programming software tools for modeling and analyzing the effectiveness of the overload control mechanisms in SIP-server networks. The modeling process utilizes mathematical and simulation models as well as simulato...

The impact of technological advances within information and communication technology (ICT) cannot be exaggerated. Instant availability of communication via faxes, mobile telephones, electronic mail, pagers and video conferencing has enabled people to work or do business together and generally interact despite being temporally and spatially “dislocated”. This is all well and good, but if technol...

Disasters such as the 9/11 attacks, as well as major and unpredictable events, can cause extreme network overload. By \extreme overload" we mean, rst, that the ooered load at a link is signiicantly higher than the link's capacity, and second, that the average throughput per session is too low. Under such conditions, the network can suuer from a form of \livelock" in which even though links are ...

The increment in the prevalence of obesity incidence in Mexico is leading to the increase in many chronic maladies, including liver diseases. It is well known that lipid-induced liver sensitization is related to the kind of lipid rather than the amount of them in the organ. Cholesterol overload in the liver aggravates the toxic effects of canonical liver insults. However, the status on the repa...

Based on clinical and experimental work two new types of volumetric overload shocks are reported: volumetric overload shock type one and type two depending on the type of fluid causing their induction. Volumetric overload shock type one is induced by sodium-free fluids such as glycine, glucose, mannitol and sorbitol and is characterized with acute dilutional hyponatraemia. Volumetric overload s...
