INTRODUCTION Though measles is a vaccine preventable disease, outbreaks still continue to occur because of poor immunization coverage rate at the national level. OBJECTIVE To report the survey results of an outbreak of measles in Puraini village of Madhepura district in Bihar, India. MATERIALS AND METHODS This cross-sectional survey was conducted among children aged 6 months to 12 years dur...
OBJECTIVE To investigate the risks of the sudden infant death syndrome and factors that may contribute to unsafe sleeping environments. DESIGN Three year, population based case-control study. Parental interviews were conducted for each sudden infant death and for four controls matched for age, locality, and time of sleep. SETTING Five regions in England with a total population of over 17 mi...
OBJECTIVE To estimate prevalence of childhood-onset Duchenne and Becker muscular dystrophies (DBMD) in 6 sites in the United States by race/ethnicity and phenotype (Duchenne muscular dystrophy [DMD] or Becker muscular dystrophy [BMD]). METHODS In 2002, the Centers for Disease Control and Prevention established the Muscular Dystrophy Surveillance, Tracking, and Research Network (MD STARnet) to...
In this paper we describe an approach to the identification of “translationese” based on monolingual comparable corpora and machine learning techniques for text categorization. The paper reports on experiments in which support vector machines (SVMs) are employed to recognize translated text in a corpus of Italian articles from the geopolitical domain. An ensemble of SVMs reaches 86.7% accuracy ...
This paper is based on ten consecutive 1991 issues of two Murdoch newspapers in Britain, The Sun and The Times, plus a further ten each from 2008, focusing mainly on editorial articles. All four subcorpora derive from periods in which a UK government, having enjoyed power for an extended period, was visibly weakening and the ideology expressed was, therefore, of some significance. It is claimed...
Perturbation of a steadily propagating crack with a straight edge is solved using the method of matched asymptotic expansions (MAE). This provides a simplified analysis in which the inner and outer solutions are governed by distinct mechanics. The inner solution contains the explicit perturbation and is governed by a quasi-static equation. The outer solution determines the radiation of energy a...
The relationship between placental characteristics, including weight and inflammation, and pregnancy outcome was examined as part of a case control study looking into the impact of maternal HIV-1 infection on pregnancy outcome. Cases defined as low birth weight (< 2500g) or stillbirth deliveries, were compared to controls defined as mothers who delivered a live born neonate weighing 2500g or mo...
Application of pile-raft foundations, which are known as “compound foundations”, is a suitable alternative in the case of heavy load structures. The interaction behavior of pile raft foundations makes these systems very complex to analyze. Different methods have been proposed to determine the bearing capacity of piled raft systems and distribution of loads between the components, i.e. pile grou...
ابزارهای metacase همانند ابزار case، وسیله ای برای کمک به مهندسین نرم افزار در تحلیل، طراحی و ایجاد یک سیستم هستند. مزیتی که یک ابزار metacase بر یک ابزار case دارد، قابلیت انعطاف بالای آن است که متدولوژیهای مختلفی را پشتیبانی می کند و در نتیجه هر سازمان قادر است برای متدولوژی خاص خود، case موردنظر را توسط آن تعریف کند. هدف از این پایان نامه طراحی یک metacase است که به کمک آن بتوان متدولوژیهای ...
Decline curve analysis has some advantages over transient well test analysis in which it is not required to shut-in the well and also wellbore storage effects do not exist. Few studies have been done on decline curve analysis of naturally fractured reservoirs but there are even some limitations with available models. On the other hand well test could be expensive and in some operational conditi...
