  • Of the four heart valves, the mitral valve is the only valve that has a distinguishable annulus. However, the presence of a fibrous annular structure is variable and discontinuous. The firmest site of support for the mitral valve is the region of fibrous continuity between the aortic and mitral valves, the extent of which is delineated by the right and left fibrous trigones (Fig. 2). Nevertheless, for surgical purposes, the annulus is considered the area of attachment of the valve leaflets to the atrial muscle. The annulus is a functional component of the mitral valve.

  • Hence, tourism marketing should not only be regarded as a tool for attracting more visitors to a region, as it has been the case for most destinations. Instead, tourism marketing should operate as a mechanism to facilitate regional development objectives and to rationalise the provision of tourism in order to ensure that the strategic objectives of destinations are achieved. Tourism marketing should also ensure equitable returns-on-resources-utilised for the production and delivery of tourism products, as well as the regeneration of these resources.

  • The statistics are well known and staggering. And yet, in many countries the figures continue to worsen. Each year 500,000–600,000 women die in pregnancy and childbirth. In some parts of Sub–Saharan Africa, 1 in 6 women die in child birth, while in United States the lifetime risk is as low as 1 in 84001. HIV/AIDS statistics tell an equally disturbing story of dis- parity. In parts of Africa, over 35% of the adult population — 1 in 3 adults — is infected with HIV 2. The number of women contracting the disease is also on the rise.

  • A person who had the cancer and died 10 years later of the cancer would contribute an event, a death due to the cancer, having also contributed 10 person-years of survival time. A 90 % cancer specific survival at 10 years would mean that 90 % of patients had not died from their cancer, while 10 % had died from their cancer (Kaplan, 1958). Calculation of cause-specific survival is especially important when studying diseases with a favorable prognosis, as is the case at hand, where the patients live long enough to be exposed to other causes of death....

  • In addition McQueen and Vorkink (2004) are able to reproduce GARCH volatility using a preference-based model with time-varying sensitivity to news. In a related paper, Vanden (2005) develops a model where the representative agent exhibits a utility function with several risk aversion regimes, which in equilibrium leads to volatility regimes and volatility clustering.

  • Again, however, an appropriate comparisons needs to take account of the fact that the SEC took place four years later and the process of cohort succession would affect results in the same way as was noted for literacy with respect to comparisons with the census. Thus when DHS results are calculated for persons aged 56 and older (who would be 60 and older in 2004) and limited to the provinces covered by the SEC sample, the percentages who ever attended school are reasonably similar in the two sources. Overall the comparison of basic demographic characteristics from the 2004...

  • In the end, I curled up on a bench in Peel Park, hidden under a rattly newspaper, and slept for what felt like ten seconds before a PCSO woke me up with a rough shake and a bright light in my eyes and sent me back to wander the streets. It was coming on dawn then, and I had a deep chill in my bones, and a drip of snot that replaced itself on the tip of my nose every time I wiped it off on my sleeve. I felt like a proper ruin and misery-guts when I finally dragged my arse back home, stuck...

  • The real estate impact of arts and cultural activities is seen not only in the redevelopment of discrete buildings, but in the incremental renewal of large districts involving complex social and design solutions. The physical expression of place-making by the creative sector often plays out over decades. Older urban neighborhoods are filled with architecturally- distinct buildings that exist in the interplay of recently re-built and longer term deteriorated sites.

  • In some ways, the uncertainty over supply consistency is really a form of risk management. In the future, both petrochemical supply and renewable supply will carry increased risk. For petrochemicals, further supply uncertainty may arise from political changes in other world areas. For plant-derived materials, weather may be an uncertain factor locally, while specialty plants with less commodity type production may result in more trading uncertainty.

  • Historically speaking, the earliest asset pricing models made rel- atively simple predictions about what it means for a benchmark to be OE to a managed portfolio. The Capital Asset Pricing Model of Sharpe (CAPM, 1964) implies that all investors should hold a broadly diversified “market portfolio,” combined with safe assets or “cash,” according to the investor’s tastes for risk. It follows that an OE portfolio is a broadly diversified portfolio, combined with safe assets or cash, mixed to have the same market risk exposure, or “beta” coefficient as the fund.

  • Vaginal pool smear: The aspiration can be performed after the introduction of unlubricated speculum. The technique allows collection of cells under direct vision from posterior fornix pool. When a speculum is not employed the pipette is gently introduced in to the vagina until resistance is encountered. It is important to compress the suction bulb during the introduction of the pipette to avoid collecting the cellular material of the lower vaginal origin. The cellular material is spread on a clean glass slide and fixed immediately.

  • One of the most significant contributions of the MEASURE DHS program is the creation of an internationally comparable body of data on the demographic and health characteristics of populations in developing countries. The DHS Comparative Reports series examines these data across countries in a comparative framework. The DHS Analytical Studies series focuses on specific topics. The principal objectives of both series are to provide information for policy formulation at the international level and to examine individual country results in an international context.

  • Some female respondents had accessed PMTCT services when pregnant. Among women not on ART, knowledge of PMTCT and where to obtain services was poorer. Women perceived PMTCT counselling on infant feeding, contraception, and dual protection to be inadequate. Many women not receiving ART knew that antiretroviral drugs were available at the clinics they were attending and knew that they did not yet qualify for the drugs. They knew little of the health effects of the therapy, however.
