摘要:Raman spectroscopy results obtained for undoped and Al‐ and/or Mn‐doped ZnO thin films produced by RF‐sputtering are reported. The effect of the doping method (either co‐sputtering or ion implantation), the dopant type, and its concentration on the Raman‐active vib...

摘要:ABSTRACT(#br)Hydrocarbon reservoirs are generally located beneath complex geological structures. Frequently, such areas contain seismic diffractors that carry detailed structure information in the order of the seismic wavelength. Therefore, the development of computational f...

摘要:Abstract(#br)A basic serine protease which is active on casein and fibrinogen was purified from Bothrops moojeni venom using a single step chromatography on a CM‐Sepharose fast flow column. The enzyme, MOO3, was not hemorrhagic and presented only a trace of blood‐clotting ac...

摘要:In the early 1980s, Portugal could be classified as a highly endemic area for hepatitisA. However, marked economic and sanitary improvements took place during the following years. In this study we evaluated the temporal trends in the prevalence of hepatitisA in children and ...

摘要:Summary(#br)Two experiments were conducted to evaluate the relationship among the level of feed intake, chewing pattern, and diet digestibility in sheep fed a moderate‐concentrate diet. The first experiment was conducted using six male lambs at a replicated 3 × 3 Latin squar...

摘要:Abstract(#br)A Raman spectroscopy study of doped versus undoped ZnO layers is presented. The layers were grown by RF magnetron sputtering and the doping with Al, Sb and Mn was achieved by ion implantation with subsequent annealing. First‐order Raman response measured under λ...

摘要:Abstract(#br)In order to improve the transparent contact layer in amorphous silicon solar cells fabricated on low‐temperature plastic substrates, Al and Ga doped ZnO films were deposited at room temperature on plastic and glass and their optical, electronic and structural pr...

摘要:Abstract(#br)In this paper, we propose a novel decomposition approach (named PBGS) for stochastic mixed‐integer programming (SMIP) problems, which is inspired by the combination of penalty‐based Lagrangian and block Gauss–Seidel methods. The PBGS method is developed suc...
