A set is an unordered (unless otherwise specified) collection of elements of the same type, usually expressed using the following notation: {elem1, elem2, elem3, . . .} A tuple is an ordered collection of elements, not necessarily of the same type, expressed using the following notation: (elem1, elem2, elem3, . . .) Most of the times, we don’t give too much attention to the actual elements them...

The simplest interpretation of the global success of the Standard Model is that new physics decouples well above the electroweak scale. Supersymmetric extension of the Standard Model offers the possibility of light chargino and the right-handed stop (with masses below MZ), and still maintaining the successful predictions of the Standard Model. The value of Rb can then be enhanced up to ∼ 0.218 ...

We used quantitative genetics techniques to compare the entrepreneurial activity of 870 pairs of monozygotic (MZ) and 857 pairs of same-sex dizygotic (DZ) twins from the United Kingdom. We ran model-fitting analyses to estimate the genetic, shared environmental and nonshared environmental effects on the propensity of people to become entrepreneurs. We found relatively high heritabilities for en...

I n the past 2 decades, preventable injuries in children and adolescents have been on the decline. This decrease in injuries is a positive outcome of many years of injury prevention activities; however, one area in which injury rates are on the rise is drug poisoning. In fact, the number of poisoning incidences in youth aged 15 to 19 years doubled between 2000 and 2009. This sharp increase in p...

OBJECTIVES To determine the prevalence of sharp instrument injuries in hospital-based healthcare workers (HCWs) in mainland China and the contributing factors. DESIGN Cross-sectional study. SETTING The data were derived from public hospitals. PARTICIPANTS A total of 360 hospitals were recruited in the study, including 289 general hospitals and 71 specialised hospitals. Among them, 194 are...

Sir, Accidental needle stick and sharp object injuries carry major risk factors for blood-borne infections amongst health workers.[1,2] The blood-borne infections that are mostly contracted through occupational hazards are Hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV).[3] The risk of transmission of these diseases following percutaneous exposure among h...

Introduction Advances in diagnostic imaging have led to remarkable improvements in the diagnosis and treatment of pancreatic disorders. However, the diagnosis and treatment of pancreatic injury remains perplexing. Since the pancreas is a retroperitoneal organ that is narrow and elongated mediolateraly, diagnosing only the presence or absence of injury, let alone its location and extent, is difi...

The incidence of needle-stick injuries and the reporting attitudes among dentists in the north of Jordan were assessed with a cross-sectional survey. The study included 170 general dental practitioners (119 males and 51 females), of whom 113 (66.5%) were injured within the preceding 12 months. Needle-stick injury was significantly associated with higher age and a higher number of patients treat...
