BACKGROUND Many studies in adults had identified factors associated with partly or uncontrolled asthma. In children, factors related to asthma control were not well defined. OBJECTIVE To find the factors related to partly or uncontrolled asthma in children. METHODS Asthmatic children who had severity at least in the mild persistent level, were recruited. The asthma control levels were class...

Supplier selection is a multiattribute decision making (MADM) problem which contains both qualitative and quantitative factors. Supplier selection has vital importance for most companies. The aim of this paper is to provide an AHP based analytical tool for decision support enabling an effective multicriteria supplier selection process in an air conditioner seller firm under fuzziness. In this a...

In this work, an internet of things (IoT) sensing and monitoring box has been developed. The proposed low-cost system is a portable device for smart buildings to measure vibrations, monitor, control noise caused by the industrial machines. We will present instrument method vibration tilt mechanical (air conditioner). primary goal create signal acquisition that both user-friendly affordable, whi...

This study examined the sensitivities of the neuronal responses in the inferior colliculus (IC) to the interaural phase difference (IPD) of a preceding tone, and explored its implications in the neural-population representation of the IPD. Single-unit responses were recorded from the IC of anesthetized gerbils. The stimulus was a dichotic tone sequence with a common frequency (typically the uni...

One tasks facing ...

Name: S u s a n W. S t e w a r t Brief Description: The HCFC refrigerant, R-22, is the most widely used residential air-conditioner refrigerant in the U.S. However, it is scheduled to be banned in new equipment beginning in 2010 due to its high ozone depletion potential (ODP). A new refrigerant, R-410A has zero ODP and favorable performance characteristics such as good cycle efficiency, non-fla...
