These experiments tested the hypothesis that a relatively short duration of controlled mechanical ventilation (MV) will impair diaphragmatic maximal specific force generation (specific P(o)) and that this force deficit will be exacerbated with increased time on the ventilator. To test this postulate, adult Sprague-Dawley rats were randomly divided into one of six experimental groups: 1) control...

Mechanical ventilation is an essential component of the care of patients with ARDS, and a large number of randomized controlled clinical trials have now been conducted evaluating the efficacy and safety of various methods of mechanical ventilation for the treatment of ARDS. Low tidal volume ventilation (</= 6 mL/kg predicted body weight) should be utilized in all patients with ARDS as it is the...

Computer generation of cloze tasks still falls short of full automation; most current systems are used by teachers as authoring aids. Improved methods to estimate cloze quality are needed for full automation. We investigated lexical reading difficulty as a novel automatic estimator of cloze quality, to which cooccurrence frequency of words was compared as an alternate estimator. Rather than rel...

Investigations of nerve activity have focused predominantly on electrical phenomena. Nerves, however, are thermodynamic systems, and changes in temperature and in the dimensions of the nerve can also be observed during the action potential. Measurements of heat changes during the action potential suggest that the nerve pulse shares many characteristics with an adiabatic pulse. First experiments...

Recent results suggest that quantum mechanical phenomena may be interpreted as a failure of standard probability theory and may be described by a Bayesian complex probability theory.

Predicting the outcome from NIV is important and the study by Martin-Gonzalez and colleagues applies data mining techniques to improve our understanding of the field. Nevertheless, the predictor variables must be robust and reliably available before NIV is applied. A predictive model must be generalisable in other clinical settings. Until models such as this are extremely robust in their predic...

The early modern debates on the nature of space enjoy a renewed interest in the recent philosophical literature. Focal points of the discussion are the opposition between the “absolute” vs. the “relational ” conception of space and the related issue of its presumed substantival nature. Quintessential formulations of the key positions in the debate remain the viewpoints attributed to Newton and ...

Thermodynamics study the connection between thermal and mechanical phenomena. In most thermodynamic problems, we are interested in systems, i.e. a set of bodies that undergo different transformations. These transformations are generally the result of work or heat transfer between systems, or between parts of a same system. As a result, we observe a temperature change, a variation in pressure or...
