To determine if recent cases of invasive group A streptococcal disease were caused by strains with a unique characteristic, 117 isolates Streptococcus pyogenes from patients with a variety of diseases, including necrotizing fasciitis and toxic shock syndrome, were analyzed. Significant genomic heterogeneity was observed among selected isolates, as determined using pulsed-field gel electrophores...

Sales tax holidays (STHs) are the temporary suspension of state (and some local) sales taxes on selected retail items for a brief period of time. The policy has gained popularity in recent years, beginning in one state in 1997and growing to twenty by 2008. Despite the increased frequency with which states use STHs, little research has been conducted to study how households respond to this tempo...

The authors estimated the supply of organ donors in the U.S. and also according to organ procurement organizations (OPOs). They estimated the number of donors in the U.S. to be 16,796. Estimates of the number of potential donors for each OPO were used to calculate the level of donor efficiency (actual donors as a percent of potential donors). Overall, donor efficiency for OPOs was 35 percent; t...

dehaulling is one of the important stages in sesame grain processing. it includes soaking, dehusking the grain, and separating the husks from kernels. in the present study, a continuous dehuller for an industrial continuous process layout of grain was designed, fabricated and evaluated. the slope and speed of dehuller were the main factors for laboratory experiments. results depicted both facto...
