BACKGROUND The addition of heated humidification to CPAP has been shown to improve nasal adverse effects in subjects with obstructive sleep apnea (OSA). However, current data regarding improvement in CPAP adherence is conflicting. Furthermore, there are no data from a tropical climate area with a high humidity level. METHODS In this prospective randomized crossover study conducted in Thailand...

A short-time asymptotic solution is developed for the problem of a half-space, part of the surface of which is raised to a prescribed temperature. A Green's function formulation is used to demonstrate that the heat flux at the surface can be determined from a one-dimensional analysis of the local heat conduction problem, except in the immediate vicinity of the edge of the heated area, where the...

A female patient, 36-years-old, complained of bilateral palatal pain on the anatomical area of upper second molars. The painful condition of palatal mucosa erosion was observed. Palatal erosions or ulcerations may be caused by heated food cooked in microwave ovens. We present a case of a bilateral palatal burn caused by cheese-pie. Concluding, any food containing cheese, when heated in microwav...

This is a theoretical and experimental study of microstrip reflectarray useable in wireless local area networks (WLAN). The effectiveness of reducing the unit cell size of microstrip reflectarray which is duplicated the same radiating aperture as quadratic backscatter was investigated. A reflectarray with variable element sizes and reduced grid spacing have been designed at 10 GHz. For a given ...

End-user friendly interface design is of tremendous importance for the success of mobile applications which are of increasing interest in the e-Business area. In this paper, we present an empirical evaluation of a mobile information system for improving navigation of public transport. High air pollution and respiratory dust, along with other threats to environmental conditions in urban areas, m...

This study examines the development of a new measure: The Entrepreneurial DecisionMaking Inventory to investigate a previously neglected area of research, namely entrepreneurial decision-making style. Questionnaires were distributed to 578 Victorian New Enterprise Incentive Scheme graduates resulting in 255 useable responses. Confirmatory factor analysis using AMOS 4.0 (Arbuckle and Wothke, 199...

This paper discusses practical constraints of Error Vector Magnitude (EVM) measurements for high-coverage Radio Frequency Integrated Circuit (RFIC) device testing. Noise, distortion, spurious signals, and phase noise all degrade EVM, and therefore EVM provides a comprehensive measure of an RFIC’s quality of use in digital communications. New wireless standards with large instantaneous bandwidth...
