This paper deals with a numerical investigation on sliding door and people moving effects on the indoor climate of a standard ISO5 class OT with an ultraclean air filter system and a total ceiling unidirectional diffuser. A simple method to analyze the effects on the OT climate by ... En savoir plus

Polymer gels belong to the realm of soft active materials as they are capable of responding to a non-mechanical stimulus – the permeation of a solvent – with a mechanical action – a volume change, thanks to the coupling between different physics. This mechanism of coupling can be ... En savoir plus

Introduction: This work presents the design of a novel flow cell based miniaturized electrochemical respirometer to monitor organic content in water samples semi-continuously, in contrast to current Biochemical Oxygen Demand, BOD, methods. Simulation techniques has been used to ... En savoir plus

Studying teeth grinding behavior and other oral conditions requires the ability to accurately measure the pressure on the teeth. Placing a sensor in the mouth requires small size devices with powering and measurement techniques that do not hinder the normal life of the patient. To meet ... En savoir plus

A CFD cardiac catheter model was developed to determine the potential for blood hemolysis during administration of local therapeutic hypothermia using a CoolGuide catheter. In vivo animal studies have shown that mild hypothermia may reduce reperfusion injury often associated with heart ... En savoir plus

Stroke is caused by an interruption of brain blood supply and is one of the leading causes of death and disability. A mild reduction of 2-5°C in tissue temperature through hypothermia has shown reduced tissue infarct size, increased tissue recovery, and positive neurological effects. ... En savoir plus

There is urgent need to monitor dental and oral diseases, such as tooth decay, gum diseases, and teeth grinding. Such monitoring can be achieved by embedding sensors in the mouth. This technique faces some difficulties. The first is how the power needed for the operation of the sensors ... En savoir plus

A human torso model was created for heat transfer analysis. The torso was derived from the ‘Virtual Family’ whole-body voxel data from the ITIS Foundation (Zurich, Switzerland). Measurements were taken from the ITIS male along the axial plane at key anatomical landmarks and used to ... En savoir plus

Although mammography is extremely important diagnostic technique, it suffers from some limitations such as false negative and positive results, using ionizing radiation and patient’s discomfort. Microwave imaging has been recently proposed as an additional medical imaging technique ... En savoir plus

Ectopeptidases are commonly accepted to be a means of clearing active peptides. However, studies have shown that they can also regulate peptide activity. We have developed a technique of electrokinetic push-pull perfusion (Ek-PPP, Figure 1) to examine this largely unexplored mechanism of ... En savoir plus
