Thermal comfort enhancement by using a ceiling fan
A parametric analysis on the effect of using a ceiling fan in an air-conditioned room is performed by twodimensional (2D) numerical simulation of steady state airflow and heat transfer. Thermal comfort analysis is done for a person standing in a room with an inlet and an outlet for air conditioning and a ceiling fan. Representative three-dimensional (3D) simulation is also performed for the com...

Although the book covers all areas of scientific activity, the main focus is on biology. “The optimism and resources being devoted to biological research today promise to have a profound impact on everyday life as well as philosophical notions about life itself,” writes Wilson. “Whenver artists notice so much concentration of cultural energy and focus, they feel summoned to investigate and resp...

1887 quality of care but do not substantially reduce costs among a broad array of patients.3-5 As more empirical evidence comes in, it may become easier to identify specific ways to reduce costs; for now, the possibility and scope of the savings remain unclear. One approach that might improve the cost-effectiveness of disease-management and care-coordination strategies involves more accurately ...
متن کاملMeasurement of Flow Characteristics of a Ceiling Fan with Varying Rotational Speed
This paper conducts an experimental measuring of the airflow generated by a modern ceiling fan that has an electronic device to vary the instant rotation speed for simulating natural winds. The measuring results are then used to calculate the mean air velocity, standard deviations, turbulence intensity, equivalent frequency, power spectrum, and other comfort evaluation parameters. The results h...

In This Issue In This Issue Clash of the titin he sarcomere is more than a complicated piece of structural machinery. According to new results by McElhinny et al. (page 125), a building block of striated muscle cells called MURF-1 may also indirectly regulate gene expression. MURF-1 localizes to sarcomeres thanks to its interaction with titin, a major structural component of the muscle sarcomer...
