this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...

CONTEXT Therapeutic modality control variables are thought to be thermal neutral, a term sometimes used interchangeably with room temperature. We question this common assumption. OBJECTIVE To determine thermal neutrality of common therapeutic modality control variables. DESIGN We performed 5 laboratory experiments, including (1) water temperature over 3 weeks in 3 different containers (glas...

recent research highlights the importance of gsts in the establishment of chronic helminth infections. gsts have the potential to protect the parasite against the host immune response. in this present study, gst enzyme assay has been investigated on whole extract of f. hepatica and sheep liver tissue. to the 1-ml plastic cuvette, added 200 mm potassium phosphate buffer. then added 50 mm gsh red...

for over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. on the other hand,traditional buildings of iran were designed according to ecological conditions...

is in the operating theatre Editor—In their article about the applicability of pulse pressure variation (PPV), Mahjoub and colleagues concluded that ‘a very low percentage of patients satisfied all criteria for valid use of PPV’. Importantly, the study was done in intensive care unit (ICU) patients. As a result, and not surprisingly, 49% were not mechanically ventilated, 25% were mechanically v...

This article deals with emerging multinationals post-acquisition integration approaches in developed countries. It confronts theoretical hypotheses and anecdotal evidence with unpublished empirical data. Analyzing four cases of French entities acquired by EMNE, it confirms that EMNE often adopt a partnering approach after these up-market acquisitions. Yet this approach is likely to develop in a...

In this study we have designed and created a data-fusion display that has enabled volumetric MIP image navigation using intraoperative C-arm CT data in the operating room. The 3D volumetric data reflecting a patient's inner structure is directly displayed on the monitor through video images of the surgical field using a 3D optical tracking system, a ceiling-mounted articulating monitor, and a s...
