Experiments have been performed at ASDEX Upgrade, aiming to investigate the impact of lithium in an all-metal-wall tokamak and attempting to enhance the pedestal operational space. For this purpose, a lithium pellet injector has been developed, capable of injecting pellets carrying a particle content ranging from 1.82 × 10(19) atoms (0.21 mg) to 1.64 × 10(20) atoms (1.89 mg). The maximum repeti...
OBJECTIVES To describe a gun exchange program and assess potential benefits for participants and host communities. METHODS Mail survey of participants in a Sacramento, California gun exchange program, August 1993; the response rate was 79%. Comparative data were obtained from nationwide polls of gun owners. RESULTS Most (62%) respondents were men; 40% were more than 55 years old; none was l...

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...
Oblique impact of cylindrical projectiles with blunt, conical and hemispherical noses with different aspect ratios on metallic targets with different thicknesses is investigated and penetration critical angle is determined. Circular targets of Al1100-H12 had a diameter of 240mm and thicknesses of 1, 2 and 3mm. Steel work hardened projectiles with blunt, conical and hemispherical noses are made ...
This research was conducted in order to determine chemical composition, gas production parameters, in vitro digestibility and ruminal degradability of Acroptilon repens at different phonological stages (vegetative, flowering and seeding) and its comparison with alfalfa hay and wheat straw in Completely Randomized Design. For this purpose, Acroptilon repens was prepared in three stages of growth...
Radon is one of the most important radioactive gases.Radon emits alpha particles and ultimately,it can cause genetic disorders.There are many reports of carcinogenesis and its harmful effects.One way to get this gas into the body is by eating and drinking.In the meantime,milk is one of the most consuming foods that can be contaminated with radon.In this study, the concentration of radon gas was...
Three unrelated patients attended the accident and emergency department with pain and blurred vision after ocular injury with a Nerf gun.
