This paper examines the merit of two propositions at the center of the debate on gun control in the aftermath of mass shootings in the United States: (1) gun violence and mass shootings are a cultural artifact (gun enthusiast perspective); (2) gun violence and mass shootings are more prevalent due to lax regulations (pro-gun control perspective). To evaluate the value of each proposition, the s...
The purpose of the present study is to determine the effects of gun control laws and gun ownership rates on state-level suicide rates. Using the most recent data on suicide rates, gun control measures, and gun ownership rates, the results of the present study suggest that states that require handgun permits have lower gun-related suicide rates, and states that have higher gun ownership rates ha...
The natural nighttime light environment of the earth has been significantly transformed by human activities. Such “light pollution” has a profound influence on ecosystems. Protected areas (PAs) play key ecological functions and are only effective at low light pollution levels or without any light pollution. In China, with rapid population growth and high urbanization rates, light pollution in P...
Abstract Recoil reduction is one of the most important issues for design aircraft gun. Traditional approaches this purpose will produce back-blast, which constitutes a hazard to fighter planes or attack helicopters. This paper presents closed type gas reflection device gun aiming reduce recoil force without ejecting propellant rearward. The launching process modeled by coupling classical interi...
Every synchrotron accelerator requires a pre-injector for primary injection of the electrons into the booster ring. The Iranian Light Source Facility (ILSF) pre-injector is a 150 MeV S-band linear accelerator with a thermionic cathode RF gun. The design of the pre-injector lattice and its beam dynamics calculation results together with the design of RF gun, alpha magnet, quadrupole magnets and ...
Parturition time has been chosen to investigate whether a photoinducible phase exists during the light-dark cycle in the rat. A 1-hr light stimulation was given during the dark phase at various times after the beginning of the principal photoperiod or conventional dawn. The rats kept under 8 hrs of light and 16 hrs of darkness from mating (day 1 of pregnancy) gave birth to most of their pups on...
