In the context of the standard SUSY GUT scenario, we present a detailed analysis of the softly broken finite supersymmetric grand unified theory. The model, albeit non-minimal, remains very rigid due to the requirement of finite-ness. It is based on the SU (5) gauge group and is UV finite to all orders of perturbation theory. It contains three generations of the matter fields together with four...

-A novel high and low speed output buffer circuit is proposed for Universal Serial Bus (USB) interface applications. Operation principles of this novel buffer are developed based on slew rate control and delayed turn-on technique. The mechanism for slew rate control is process variation self compensating. So, both precise rise and fall times of the output signal have been obtained for low speed...

Background: Although much concern has been expressed about the occupational risk posed to surgeons by the HIV pandemic infection, the paediatric age group is often seen as less likely to harbor the disease. Aim: To determine the HIV infection rate among children presenting for surgical operations at the Lagos University Teaching Hospital (LUTH), Lagos. Materials, patients and method: Blood was ...

This study investigated dental and dental hygiene students' a) perceptions of their education about treating patients with HIV infections/AIDS, b) knowledge of universal precautions, c) attitudes towards treating these patients and patients perceived to be at risk for HIV infections, and d) evaluations of potential curricular activities such as discussion groups with HIV-infected patients. Data...

Previous studies suggest that the implementation of universal precaution (UP) plays a role in reducing HIV stigma. In this study we investigate the efficacy of a stigma reduction intervention on UP compliance and explore whether UP compliance could potentially influence HIV stigma reduction in medical settings. A randomized controlled intervention trial was conducted in two provinces of China w...

We present an inexpensive hand-held device (240 g) that implements microchip isotachophoresis (ITP) with laser induced fluorescence (LIF) detection. This self-contained instrument integrates the functionality required for high voltage generation onto a microelectronic chip, includes LIF detection and is powered by a universal serial bus (USB) link connected to a laptop computer. Using this devi...

BACKGROUND The incidence of HIV infection and AIDS is rising in Nigeria. Surgeons are at risk of occupationally acquired infection as a result of intimate contact with the blood and body fluids of patients. This study set out to determine the knowledge, attitude and risk perception of Nigerian surgery residents to HIV infection and AIDS. METHODS A self-administered postal questionnaire was se...

Hospital May Lose Federal Funding for Discriminating Against HIVPositive Healthcare Worker A New York state case marks the first time that the Department of Health and Human Services (HHS) has ordered termination of a hospital’s federal funds, some 40% of this hospital’s revenue, for a civil rights violation since the implementation of Medicare’s hospital prospective payment system. This hospit...

Health-care workers are at risk of exposure to occupational infections with subsequent risk of contracting diseases, disability, and even death. A systematic collection of occupational disease data is useful for monitoring current trends in work situations and disease exposures; however, these data are usually limited due to under-reporting. The objective of this study was to review literature ...

Background Several water-based sports (swimming, surfing and stand up paddle boarding) require adequate thoracic mobility (specifically rotation) in order to perform the appropriate activity requirements. The measurement of thoracic spine rotation is problematic for clinicians due to a lack of convenient and reliable measurement techniques. More recently, smartphones have been used to quantify ...
