synthetic water soluble acrylamide-based polymers have wide range of ap-plications  in  the  feld  of  soil  establishment  and  non-desertifcation.  in  this research, the acrylamide-based anionic polyelectrolytes were prepared by  solution polymerization. the polymerization was carried out using aibn as a radical initiator and at different degrees of anionic charges ranging between 10% and 30...

the aim of this study is to map the chronological achievements of public health over the past 100 years in a small island state and to outline emerging themes. a retrospective analysis of data was conducted from the published population and vital statistics reports of the central statistical office for the period of 1953-2006, as well as all available published reports of the ministry of health...

SUMMARY We present the software implementation of the tree scanning method to detect associations between genetic haplotypes and quantitative traits, utilizing the evolutionary history of the haplotypes, in samples of unrelated individuals. AVAILABILITY The program is available free of charge, under the GNU General Public License. A package including C source code, a Makefile, and Windows (DO...

A difficulty frequently experienced by the public health officials and workers in charge of maternity relief and child-welfare organizations in this country is in getting reasonably correct statistics of maternal mortality. The -extraordinary variations in the maternal death-rates recorded in the different provinces and in cities in the same province are so incredible that little value can be a...

The first Web-based version of the NIST X-ray Photoelectron Spectroscopy Database (XPSDB) is described. The current database, built from a relational database management system (RDBMS), contains critically evaluated data with over 19,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. It is available free of charge to the pu...

The present paper revisits the issue of rational decision making in John Rawls’ original position. Drawing on Isaac Levi’s theory of decision, I discuss how we can defend Rawls against John C. Harsanyi’s charge that maximin reasoning in the original position is irrational. The discussion suggests that systematic application of Levi’s theory is likely to have important consequences for ethics an...

It appears that fourteen years ago the Legislative Act establishing this Board enjoined upon its members the following charge : " They shall investigate and supervise the whole system of the public charitable and correctional institutions of the Commonwealth, and shall recommend such changes and additional provisions as they may deem necessary for their economical and efficient administration."...

in the present study we search potential of pt-decorated graphene (ptg) as a new nanostructure adsorbent for nitrous oxide (n2o) using density functional theory (dft). after fully relaxation of different possible orientations of n2o-ptg complex, we distinguished two optimized configurations for this system; 1- terminal n-side of gas is oriented towards pt so that the molecule axis is perpendicu...

We carried out a household survey in Khartoum state in 2001 to analyse the characteristics of those who receive free public health services and to ascertain whether there are any impediments to cost recovery policies for health care use. Data were collected through interviews based on an adapted questionnaire. Those who had other income, always or sometimes had dependents and visited the health...

Hooray, fi nally a book emerges about the human–animal interface that addresses both perspectives equitably and seamlessly. Peter Rabinowitz, a physician, and Lisa Conti, a veterinarian, effectively present material that is thorough, balanced, and of great relevance for practitioners of all varieties of medicine. More than half the pages comprise reports on each of 35 zoonoses. At the beginning...
