Background—The long term health consequences of snoring and sleep apnoea syndrome are still uncertain. This study was conducted to assess themortality risk associated with snoring and excessive daytime sleepiness (EDS), the two main symptoms of sleep apnoea syndrome, in men. Methods—In 1984 a sample of 3100 men aged 30–69 responded to a postal questionnaire including questions about snoring, ED...
SUMMARY A new type of modulation called continuous-phase parallel-combinatory high-compaction multicarrier modulation (CPPC/ HC-MCM) is proposed. CPPC/HC-MCM employs the technique of continuous-phase modulation (CPM) and avoids the formation of amplitude gaps between two successive signals to enhance the spectral efficiency of conventional PC/HC-MCM. Results of simulations show that CPPC/ HC-MC...
فرض کنید g یک گروه باشد، گروه g را جابه جایی پذیری قوی یا pc-گروه می نامند،هرگاه به ازای هر x و y در g که x^m,y^n غیربدیهی هستند، اگر [x^m,y^n]=1 آنگاه [x,y]=1 . زیرگروه های فیتینگ و عمل های دارای نقطه-ثابت-آزاد نقش اساسی در مطالعه ی pc-گروه ها دارند. یکی از اهداف ما دراین پایان نامه رده بندی pc -گروه های موضعاً متناهی است که بدین منظور ابتدا p-گروه های متناهی و گروه های پوچ توان متناهی و درنهای...
OBJECTIVE An important part of public health is identifying patterns of poor health and deprivation. Specific patterns of poor health may be associated with features of the geographic environment where contamination or pollution may be occurring. For example, there may be clusters of poor health surrounding nuclear power stations, whereas major roads or rivers may be associated with areas of po...
OBJECTIVES Recent qualitative research found young men reporting that an expectation that eating disorders (EDs) mainly affect young women led them, and others, to only recognise their symptoms when their ED had become entrenched. This raises questions about how these stereotypes persist. We therefore explored how EDs in males were represented in articles published in UK newspapers over a 10-ye...
PURPOSE To investigate the methods used at private community hospitals for delivering emergency department (ED) image interpretation services. MATERIALS AND METHODS The authors contacted a random national sample of 114 hospitals by telephone and administered an "ED Radiology Coverage" questionnaire. The questionnaire included queries about daytime image interpretation duties, nighttime radiol...
BACKGROUND Emergency departments (EDs) are an essential component of any developed health care system. There is, however, no national description of EDs in Switzerland. Our objective was to establish the number and location of EDs, patient visits and flow, medical staff and organization, and capabilities in 2006, as a benchmark before emergency medicine became a subspecialty in Switzerland. M...
objective(s) two new adjuvants from natural animal lipids (g2) and bacterial polysaccharide extracts (pc) were previously prepared by our group and showed a reduction in tracheal responsiveness. the aim of this study was to evaluate the preventive effect of recently introduced natural products (g2 and pc) on the development of asthma. materials and methods asthma was induced using a standard me...
