Among the Milky Way satellites discovered in the past three years, TriangulumII has presented the most difficulty in revealing its dynamical status. Kirby et al. identified it as the most dark-matter-dominated galaxy known, with a mass-to-light ratio within the half-light radius of M L 360

The paper starts by sketching the key modes of spatial data analysis (point pattern, continuous surface, areal/lattice), and how they fit into legacy GIS data models. Based on development work with the GRASS release 5 team (GRASS 5 is GPL), status is reported for using R in the analysis of sites (point) data and for raster data, as well as using R as an intermediate analytical environment for i...

Evolution and Testing of the Lacunar Hypothesis" by Bamford and Warlow in this issue of Stroke reviews many important aspects of these unique pathologic vascular lesions. I concur with the authors' emphasis on the need to maintain homogeneity in the classification of stroke conditions, specifically lacunes. A stroke classification scheme would ideally be based on 1) risk factor profile such as ...

We survey the recent applications and developments of sieve methods related to discrete groups, especially in the case of infinite index subgroups of arithmetic groups.

background in spite of promotion of people’s hygiene in the recent years, parasitic infection problems are present in many parts of the world especially in tropical and subtropical areas. water is one of the major sources for acquiring parasitic infections, especially protozoan parasites. objectives this study was conducted to evaluate the present parasitic agents in river, tap water and filtra...

Hypothermic low flow cardiopulmonary bypass with hemodilution technique was performed in open-heart surgery in the author's clinic. To evaluate the usefulness of this perfusicn, renal hemodynamics during total bypass, and its influence on renal function were studied. The average effective renal blood flow during total bypass at the perfusion rate of 50 to 60 ml per kg per minute under mild or m...
