BACKGROUND Studies of Primary Health Care (PHC) reveal considerable practice variations in terms of the range of services provided. In Norway, general practitioners (GPs) are traditionally expected to perform IUD-insertions and several surgical procedures as a part of comprehensive PHC. We aimed to investigate variation in the provision of surgical procedures and IUD-insertions across GPs and o...
BACKGROUND There is a large variation in referral rates to secondary care among GPs, which is partly unexplained. AIM To explore associations between reasons for referral to secondary care and patient, GP, and healthcare characteristics. DESIGN AND SETTING A cross-sectional study in Northern Norway. METHOD Data were derived from 44 (42%) of 104 randomly selected GPs between 2008 and 2010....
برخی از ترکیبات آلی و کمپلکس های فلزی با لیگاندهای شیف باز وجود دارند که در چندین شکل بلوری متبلور می شوند و هر کدام از این اشکال خصوصیات خاصی دارند و داشتن اطلاعات در مورد این اشکال بسیار مفید می باشند. در این پایان نامه مطالعات حرارتی آمورفیسم برخی از ترکیبات آلی و بررسی ساخت شیشه های مولکولی از برخی کمپلکس های فلزی که بتازگی سنتز شده اند و برخی از ترکیبات آلی، به عمل آمد. ابتدا رفتار گرماسنج...
در این پایان نامه با بررسی معادلات تفاضلی شرایط پایداری نمایی و مجانبی این معادلات را در حالات مختلف بررسی می کنیم.
INTRODUCTION Currently Australia is experiencing a rural medical workforce shortage, especially among GPs. Strategies aimed at improving this shortage have generally been directed at small and remote rural communities (RRMA 4-7); however, longstanding GP shortages also continue in large (RRMA 3) rural communities. The key to the understanding the rural workforce is the perceptions of GPs themse...
سرریزهای کنگره ای گزینه ای مناسب برای ساختگاههایی هستند که در آنها جانمایی انواع دیگر سرریزها منجر به افزایش بار آبی قابل توجهی در سد برای عبور سیلاب طراحی میباشد .استفاده از شکل هندسی مناسب برای سرریز به صورتی که بیشترین گذردهی جریان را تحت شرایط خاص هیدرولیکی همراه با کاهش هزینه ساخت داشته باشد، امری ضروری است. در این تحقیق، از قابلیت سیستم استنتاج فازی و الگوریتم تکامل تفاضلی جهت بهینه ک...
GPS multipath reflectometry (GPS-MR) is a technique that uses geodetic quality GPS receivers to estimate snow depth. The accuracy and precision of GPS-MR retrievals are evaluated at three different sites: grasslands, alpine, and forested. The assessment yields a correlation of 0.98 and an rms error of 6–8 cm for observed snow depths of up to 2.5 m. GPS-MR underestimates in situ snow depth by 10...
Acholeplasma laidlawii is killed and lysed by fresh normal guinea pig serum (GPS) without additional antibodies. Prior incubation of GPS with whole A. laidlawii organisms abolishes the killing activity of GPS. In the present study it was demonstrated that antibodies are present in normal GPS. The classical pathway, not the alternative pathway, of the complement sequence was activated by these a...
Health authorities are constantly searching for new ways to stabilise health expenditures. To explore this issue, we compared the costs generated by different types of medical practice in French general medicine: i.e. conventional (CM-GP), homeopathic (Ho-GP), or mixed (Mx-GP).Data from a previous cross-sectional study, EPI3 La-Ser, were used. Three types of cost were analysed: (i) consultation...
The purpose of this study was to evaluate the feasibility of using global positioning system (GPS) methods to understand the spatial context of obesity and hypertension risk among a sample of low-income housing residents in New York City (n = 120). GPS feasibility among participants was measured with a pre- and post-survey as well as adherence to a protocol which included returning the GPS devi...
