This study examines Americans' preferences regarding smart guns. The study builds on prior research by including previously unexamined factors, specifically victimization and comfort sharing gun ownership status with a doctor. Further, this study examines differences in preference patterns among gun owners and non-owners. Data were obtained from a nationwide online survey with 524 respondents i...

background: improvement of sleep quality is one of the major issues of human life that can help people maintain their energy resources and has beneficial effects on many behaviors. the aim of this study was to determine the sleep quality and its associated factors among students of razi school of nursing and midwifery, kerman, iran.   methods: a total of 349 students were included in this cross...

Discussions about gun policy reflect a growing willingness to treat gun violence as a public health issue. We emphatically support this movement and add our voices to the growing chorus of physicians calling for more stringent gun control. Mental illness has figured prominently in the public dialogue, and we are concerned about its conflation with gun violence in both the popular press and the ...

BACKGROUND The Highly Pathogenic Avian Influenza H5N1 virus has dramatically spread throughout Southeast Asia since its first detection in 1997. Merit Release Birds, such as the Eurasian Tree Sparrow, are believed to increase one's positive karma when kissed and released during Buddhist rituals. Since these birds are often in close contact with both poultry and humans, we investigated their pot...

neonates with respiratory distress syndrome (rds), who are treated according to insure protocol; require arterial blood gas (abg) analysis to decide on appropriate management. we conducted this study to investigate the validity of pulse oximetry instead of frequent abg analysis in the evaluation of these patients. from a total of 193 blood samples obtained from 30 neonates <1500 grams with rds,...

Abstract The Hugoniot parameters of U71Mn steel under high pressure were studied by hypervelocity impact test with two-stage light gas gun. plate sample was carried out means symmetrical impact. minimum speed 1.843km/s and the maximum 5.018km/s. relation parameter C λ, then accuracy is verified according to equation state (the relationship curve between density). research results can provide re...

The U.S. Geological Survey National Water Quality Assessment Program has completed a number of water-quality prediction models for nitrogen and phosphorus for the conterminous United States as well as for regional areas of the nation. In addition to estimating water-quality conditions at unmonitored streams, the calibrated SPAtially Referenced Regressions On Watershed attributes (SPARROW) model...

Here we show how a migratory songbird, the chipping sparrow (Spizella passerina), achieves prompt and precise vocal imitation. Juvenile chipping sparrow males develop five to seven potential precursor songs; the normal development of these songs requires intact hearing but not imitation from external models. The potential precursor songs conform with general species-typical song parameters but ...

Externally controlled diffuse discharge switches offer the potential of submicrosecond opening time and high repetition rate. For the investigation of an electron-beam controlled diffuse discharge, an e-beam gun was constructed which allows submicrosecond, multiple pulse operation. The 200 kV, 100 cm2, e-beam with thermionic cathode is designed as a triode. The control grid is pulsed to generat...
