Rheumatic Fever: Natural History and Treatment

Major advances in clinical and laboratory research methods have significantly clarified the identification and natural course of rheumatic fever in the past two decades

Characterizing the propagation of gravity waves in 3D nonlinear simulations of solar-like stars

The revolution of helio- and asteroseismology provides access to the detailed properties of stellar interiors by studying the star's oscillation modes. Among them, gravity (g) modes are formed by constructive interferences between progressive internal gravity waves (IGWs), propagating in stellar radiative zones. Our new 3D nonlinear simulations of the interior of a solar-like star allows us to study the excitation, propagation, and dissipation of these waves. The aim of this article is to clarify our understanding of the behavior of IGWs in a 3D radiative zone and to provide a clear overview of their properties. We use a method of frequency filtering that reveals the path of {individual} gravity waves of different frequencies in the radiative zone. We are able to identify the region of propagation of different waves in 2D and 3D, to compare them to the linear raytracing theory and to distinguish between propagative and standing waves (g modes). We also show that the energy carried by waves is distributed in different planes in the sphere, depending on their azimuthal wave number. We are able to isolate individual IGWs from a complex spectrum and to study their propagation in space and time. In particular, we highlight in this paper the necessity of studying the propagation of waves in 3D spherical geometry, since the distribution of their energy is not equipartitioned in the sphere.Comment: 14 pages, 12 figues, accepted by Astronomy & Astrophysic

A History of Quality of Life Measurements

Purpose: To review the origins and early development of quality of life measurements in the medical literature. Methods: A comprehensive literature review of Medline from 1966-1986 examining articles with quality of life as a subject heading. Studies were included if they were the original article describing a scales development or used scales developed in the social science literature. Results: The measurements have been derived from two separate sources: a transfer and expansion of medical appraisals for health status, and an application of sociometric and psychometric methods for populational assessment of happiness, well-being, and other affects. Neither source of measurements used the basic principle that a persons quality of life is a state of mind, not a state of health, and that a suitable personal expression should allow the opportunity to cite distinctive individual feelings. In addition, the existing approaches are often unsatisfactory for denoting changes. Conclusions: Since quality of life of individual patients was not directly sought with the two original sources, its appraisal may be improved with an old clinical method of asking patients what they believe

Kekuasaan dalam Pemikiran Ibnu Khaldun

There are different things from the view of Ibn Khaldun the focus of political science itself. In line with Aristotle that human beings are involved in politics (zoon politicon), that the main object of study is the man himself and his relationship with the universe. Simply put, Ibn Khaldun puts man as great as a regulator of the life on earth.Keywords : Thinking, Powe

Biodiversity of Camp Joseph T. Robinson Military Installation in North Little Rock, Arkansas 1994-1995

In 1994 the University of Arkansas - Little Rock (UALR), in cooperation with the Nature Conservancy and the Arkansas Natural Heritage Commission, began a faunal assessment of Camp Joseph T. Robinson MilitaryInstallation in North LittleRock, Arkansas. The purpose ofthe study was (1) to determine the distribution and the abundance ofnative ? fauna on the installation, (2) to survey the installation for rare and endangered species, and (3) to determine the impact ofhuman activities on sensitive habitats and on the fauna. During the fall (1994-1996), winter (1995-1996) and spring « (1995-1996) seasons, mammals were located by either live-trapping, mist-netting, scent stations, pitfall trapping, active hunting orspotlighting. Arc/INFO® and ArcView® 2.0 were used to visualize and analyze the data. ERDAS Imagine\u27\u27 was « used for satellite imagery interpretation. We recorded 315 individuals representing 29 of the 54 possible mammalian species within central Arkansas. Two additional species were documented from UALR museum records. When habitats * were categorized into either Hardwood or Mixed Hardwood/Pine, we found more species occurring in Mixed Hardwood/Pine areas than in Hardwood areas. When the two habitat-associations were compared (techniques by ? Hutcheson; 1970 and Zar; 1996) there was no significant difference (
