Between 0.65 K and 3.2 K, the temperature dependence of the vapor pressure P of 3He is defined by the International Temperature Scale of 1990 (ITS-90). However, the ITS-90 vapor pressure equation was not designed to be consistent with the scaling law required for the second temperature derivative of the vapor pressure in the vicinity of the liquid-vapor critical point. In this paper, two scalin...

Mechanical ventilation can be life saving in critically ill infants and children, but has important complications. As a consequence, newmodesofmechanical ventilationhavebeen introduced in an attempt to reduce baro/volutrauma. The modes include thosewhich avoid intubation, such as continuouspositive airwayspressure (CPAP),minimize excessive volumes, i.e., volume-targeted ventilation (VTV) and hi...

BACKGROUND The rapid shallow breathing index (RSBI) is the most widely used index within intensive care units as a predictor of the outcome of weaning, but differences in measurement techniques have generated doubts about its predictive value. OBJECTIVE To investigate the influence of low levels of pressure support (PS) on the RSBI value of ill patients. METHOD Prospective study including 3...

Trophic interactions play a critical role in the structure and function of ecosystems. Given the widespread loss of biodiversity due to anthropogenic activities, understanding how trophic interactions respond to natural gradients (e.g., abiotic conditions, species richness) through large-scale comparisons can provide a broader understanding of their importance in changing ecosystems and support...

W ITH THE INTRODUCTION of intensive care units in the 1960s an environment was established for aggressive patient care. Current technologic achievements continue to improve the means by which this care is provided. Hemodialysis, ventilators, parenteral nutrition, and ventricular assist devices all offer temporary, or occasionally permanent, support for failing organ systems. Extracorporeal circ...

The general approach to the nutritional care of the catabolic, malnourished or critically ill patient involves delivery of a balanced diet including energy (in the form of carbohydrates and lipids), an adequate amount of nitrogen, all essential nutrients (amino acids, fatty acids, vitamins, electrolytes) and fluid [1]. Traditionally, the qualitative and quantitative composition of dietetic meas...

We present the concept of an agenda and apply this concept to the formal speciication of software for safety-critical applications. An agenda describes a list of activities to solving a task in software engineering, and validations of the results of the activities. Agendas used to support the application of formal speciication techniques provide detailed guidance for speciiers, schematic expres...

prediction of available vapor pressure data in the case of compounds containing c-h-o led to derivations and recommendations of standard equations for this property. the accuracy of vapor pressure estimations is essential to use as a basis to calculate acentric factor, thermal and equilibrium properties. in this study, according to the previous work, an accurate equation to estimate vapor press...

This paper presents an empirical investigation of the critical determinants for the adoption of e-market in Australian small-and-medium sized enterprises (SMEs) within the technology-organization-environment (TOE) framework. A conceptual model is proposed for better understanding the adoption of e-market in Australian SMEs. Structural equation modelling is used for testing and validating the co...
