Theoretically, HIV could be eliminated from endemic countries if entire populations were tested and enough infected individuals were treated with antiretroviral drugs, but the frequency of testing required and the proportion of those infected who would need to receive treatment are unclear. Mirjam Kretzschmar et al. (pp. 15538– 15543) developed a model of HIV transmission that incorporates the ...

Context. This paper presents the results of a pilot redshift survey of 18 candidate compact groups from the distant DPOSS survey that extends the available surveys of compact groups of galaxies to z ∼ 0.2 in redshift, mainly Hickson Compact Groups and Southern Compact Groups. Aims. The goal of our survey was to confirm group membership via redshift information and to measure the characteristic ...

Medical malpractice cases are a matter of much concern in many countries including Malaysia where several cases caught the attention of the public and authorities. Although comprehensive annual statistics on medical negligence claims are not available in Malaysia since such data are not collected systematically in this country there are indications of an upward trend. Medical malpractice cases ...

Clusters of galaxies may contain cluster-wide, centrally located, diffuse radio sources, called halos. They have been found to show morphologies similar to those of the X-ray emission. To quantify this qualitative statement we performed a point-to-point comparison of the radio and the X-ray emission for four clusters of galaxies containing radio halos: Coma, Abell 2255, Abell 2319, Abell 2744. ...

AIM To analyze melanoma incidence and mortality trends in Croatia 1988-2008, compare them with the trends in other populations, and identify possible changes in the trends. METHODS Incidence data were obtained from the Croatian National Cancer Registry and the mortality data from the Croatian Bureau of Statistics. United Nations population estimates were used for calculating the age-specific ...

We present results from a search to detect radio emission at 1.4 GHz from gravitationally lensed arcs towards galaxy clusters. Using the FIRST survey observations of galaxy cluster fields, we have clearly detected 1.4 GHz emission at the location of bright arc towards the galaxy cluster Abell 370. The possibility that this emission is associated with a projected galaxy superimposed on the arc c...

We show that observational data for four Abell clusters of galaxies support the Gurzadyan-Kocharyan relation between the Hausdorr dimension and the dynamical properties of a galaxy system. The Hausdorr dimension is calculated using the two-point correlation function, while the dynamical parameters are estimated using available data and reasonable assumptions on the mass function of galaxies. Th...

BACKGROUND Ethics is one of the main pillars in the development of science. We performed a JoinPoint regression analysis to analyze the trends of ethical issue research over the past half century. The question is whether ethical issues are neglected despite their importance in modern research. METHOD PubMed electronic library was used to retrieve publications of all fields and ethical issues....

This study investigated the determinants of dividends policy in the Nigerian stock exchange market. To achieve the objectives of this study, a total of 50 listed firms in the Nigerian stock exchange market were selected and analyzed for the study using the judgmental sampling technique. Also, the corporate annual reports for the period 2006-2011 were used for the study. The paper was basically ...

BACKGROUND The objective was to determine secular trends in unintentional fall-related hospitalizations in people aged 65 years and older in the United States. MATERIALS Data were obtained from a nationally representative sample of emergency department visits from January 1, 2001, to December 31, 2008, available through the National Electronic Injury Surveillance System-All Injury Program. Th...
