Knowing the presence or the actual number of occupants in a space at any given time is essential for the effective management of various building operation functions such as security and environmental control (e.g., lighting, HVAC). In the past, motion detection using Passive Infrared (PIR) sensors has been widely deployed in commercial buildings and can provide data on “presence” status. Howev...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Background: Hospitals are highly vulnerable to fire because of the presence of vulnerable people (patients, medical staff, and visitors), expensive equipment, and the ignorance and low-risk perception of occupants. Injuries caused by fire can result in life and financial losses and can disrupt the performance of a hospital. Fire risk assessment is an effective way to assess vulnerability, capac...
CONTEXT Motor vehicle (MV)-related injury is a leading cause of death and emergency department visits in the US. Information has been limited regarding the magnitude and types of injuries suffered by the survivors of MV crashes. OBJECTIVE To estimate the incidence and patterns of neck strain/sprain injury among MV occupants treated in US hospital emergency departments. DESIGN AND PARTICIPAN...
Previous research in crash injury severity analysis has largely focused on level of injury severity sustained by the driver of the vehicle or the most severely injured occupant of the vehicle. While such studies are undoubtedly useful, they do not provide a comprehensive picture of the injury profile of all vehicular occupants in crash-involved vehicles. This limits the ability to devise safety...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
BACKGROUND Most studies of rear-seated occupants have focused on or included pediatric occupants which may not translate to adults. This study examines passenger, driver, vehicle and crash characteristics for rear-seated adult occupants involved in side crashes. METHODS The National Automotive Sampling System General Estimates System (NASS/GES) for calendar years 2011-2014 was used with accom...
Vehicle roll direction and occupant position have been shown to affect occupant kinematics. Data from NASS-CDS were analyzed for risk of serious or greater injuries and ejection with respect to the position of the occupant (near side or far side). The risk of AIS 3+ injuries was higher for unrestrained occupants, for ejected occupants, for occupants involved in rollovers with higher numbers of ...
