In a photoinjector electron source, the initial transverse electron bunch properties are determined by the spatial properties of the laser beam on the photocathode.Spatial shaping of the laser is commonly achieved by relay imaging an illuminated circular mask onto the photocathode.However, the Gibbs phenomenon shows that recreating the sharp edge C
Basic Ni-MH/Ni-Cd Chargers Human Values of the Russian teachers are compared with those of their colleagues from the 27 European countries, using the Schwartz Value Survey data collected in the 1990s.It was found that the average Russian teacher is extremely high in Security and extremely low in Hedonism.In addition the Russian teachers often leave
Aims: This in-vitro study aimed to compare the fatigue deformation of Polyetheretherketone (PEEK) and Cobalt-Chromium (Co-Cr) clasps by mechanical cycling test simulating ten years of use.Materials and Methods: 72 clasps samples were fabricated on a standardized e-max upper right first premolar; it is divided into 24 Co-Cr clasps, and 48 Running Bo
Wild pigs (Sus scrofa) alter ecosystems, affect the economy, and carry diseases that can be transmitted to livestock, humans, and wildlife.Understanding wild pig movements and population structure data, including natural population boundaries and dispersal, may potentially increase the efficiency and effectiveness of management actions.We trapped,
