OBJECTIVES To determine if Jamaican women of African descent with a family history of early onset autosomal dominant type 2 diabetes have greater odds of developing gestational diabetes mellitus (GDM) than those without a family history of the disease. METHODS A comparative study was conducted of two groups of pregnant Jamaican women: the first with a… (More)
 We used SCIAMACHY (10:00 LT) and OMI (13:30 LT) tropospheric NO 2 columns to study diurnal and seasonal patterns in NO 2 concentrations over India. Using characteristics of seasonal variability in tropospheric NO 2 columns, we present a simple methodology to identify the dominant NOx source category for specific regions in India. Regions where the… (More)
We give an overview of Hahn-Banach theorems. We present the statements of these theorems alongwith some definitions that are required to understand these statements and make some comments about the relevance, applications etc. Proofs are not given.
Background. There is a high incidence of failure after repair of severe perineal lacerations (SPLs). A tertiary referral hospital in the Caribbean introduced guidelines in an attempt to improve outcomes. We performed an audit of SPL repairs at this centre in an attempt to determine the effect on repair failure. Methods. All patients with SPL repairs between… (More)
We prove by elementary methods the following generalization of a theorem due to Glea-son, Kahane, and ˙ Zelazko. Let A be a real algebra with unit 1 such that the spectrum of every element in A is bounded and let φ : A → C be a linear map such that φ(1) = 1 and (φ(a)) 2 + (φ(b)) 2 = 0 for all a, b in A satisfying ab = ba and a 2 + b 2 is invertible. Then… (More)
