The 1-searcher is a mobile guard whose visibility is limited to a ray emanating from his position, where the direction of the ray can be changed continuously with bounded angular rotation speed. Given a polygonal region P with a specified boundary point d, is it possible for a 1-searcher to eventually see a mobile intruder that is arbitrarily faster than the searcher within P, before the intrud...

Remember all the to-do a couple of years ago about whether Florence Nightingale was a suitable role model l. for today's nurses? Tell you what, her common sense opinions on matters related to nurses and nursing seem just as apposite now as they undoubtedly were during her lifetime.

We review the main reasons pushing us beyond the SM and we argue in favor of new physics at the electroweak scale (hence experimentally accessible at present or near–future machines). We focus on the appealing possibility that such new physics is given by a super-symmetric (SUSY) extension of the SM. We discuss the minimal case, Constrained Minimal Supersymmetric SM, and more general (maybe mor...

BACKGROUND Bacterial meningitis continues to cause high mortality. Few studies address the possible association between this mortality and antibiotic administration delays. AIM To determine whether delays in antibiotic administration are associated with mortality from bacterial meningitis, and to identify inappropriate diagnostic-treatment sequences leading to such delays. DESIGN Retrospect...

Two separate arrests occurr­ ed at off-campus parties last night in the ND/SMC offcampus neighborhood, an area described by South Bend city officials as a “ fragile neighbor­ hood.’’ An undercover policeman dis­ guised in a gray Notre Dame sweatshirt appeared at the door of a private Finance Club cookout (1512 South Bend Ave.), claimed he was a finance major and gave his two dollar dona­ tion t...

This paper focuses on designing a tool for guiding a group of people out of a public building when they are faced with dangerous situations that require immediate evacuation. Despite architectural attempts to produce safe floor plans and exit door placements, people will still commit to fatal route decisions. Since they have access to global views, we believe supervisory people in the control r...

to investigate the effects of different salinity levels of nacl on germination of safflower (cv. esfahan 24) seeds under three different incubation methods, a factorial experiment was carried out based on a complete randomize design with three replications. salinity levels were 0, 5, 10, 15 and 20 dsm-1 (nacl) and incubation methods were sandwich method, and using petri dishes with open or clos...

The use of hospital isolation rooms has increased considerably in recent years due to the worldwide outbreaks of various emerging infectious diseases. However, the passage of staff through isolation room doors is suspected to be a cause of containment failure, especially in case of hinged doors. It is therefore important to minimize inadvertent contaminant airflow leakage across the doorway dur...
