As the size of the overall centenarian population in the United States increases, the number of centenarians participating in Social Security Administration programs grows as well. This note offers some statistical information about centenarians receiving Social Security-Old-Age, Survivors, and Disability Insurance (OASDI)--benefits and/or Supplemental Security Income (SSI) payments, highlighti...

The law of large numbers says that the sum of independent random variables is close to its expected value with high probability. In this talk, I will present a quantitative statement of this sort and demonstrate how this concentration phenomenon can be applied to problems in analysis. 1. Concentration around the expected value The most important statistical measure of a (real) random variable X...

vitamin e is a potent reactive oxygen metabolites (rom) scavenger. it is a lipid-soluble vitamin and its main function is to protect polyunsaturated fatty acids against oxidative stress. twenty-five mechanically ventilated intensive care unit (icu) adult patients participated in a prospective randomized clinical trial receiving either placebo (10 patients) or 3 im doses (1000 iu each) of vitami...

OBJECTIVES Widespread use of fluoroquinolones has led to increased levels of resistance in clinical isolates of Escherichia coli. We investigated the evolution of ciprofloxacin susceptibility and molecular epidemiology of clinical E. coli isolates in haematology patients receiving ciprofloxacin prophylaxis on the population and individual patient level. METHODS From August 2006 through Decemb...

BACKGROUND It is not known whether or not delivering acupuncture triggers mechanisms cited as placebo and if acupuncture or sham reduces radiotherapy-induced emesis more than standard care. METHODOLOGY/PRINCIPAL FINDINGS Cancer patients receiving radiotherapy over abdominal/pelvic regions were randomized to verum (penetrating) acupuncture (n = 109; 99 provided data) in the alleged antiemetic ...

AIMS The species identification and antimicrobial resistance profiles were determined for enterococci isolated from Southern California surface and ocean waters. METHODS AND RESULTS Species identification was determined for 1413 presumptive Enterococcus isolates from urban runoff, bay, ocean and sewage water samples. The most frequently isolated species were Enterococcus faecalis, Enterococcu...

development of the e-commerce in manufacturing companies and planning in this area requires knowledge on the factors affecting the decisions made by manufacturing companies to use e-commerce tools. these factors can be divided into two categories: internal and external. the internal factors show the characteristics of domestic firms that will shape their behavior, while the external factors rep...

background: although stabilization ponds and lagoons are suitable treatment processes due to simplicity of operation and low per capital costs, the effluents of these systems have too high of a total suspended solids concentration to be discharged into receiving waters. this problem is mainly caused by algae. in this study, an electro-coagulation reactor was examined to re­move algae from the f...
