Violências por professores/as contra seus/as alunos/as
(2010)
Este estudo investiga atos agressivos manifestados pelos/as professores/as contra seus/as alunos/as em sala de aula. Para tanto, recorremos às contribuições da literatura brasileira acerca da violência escolar, produzida ...
Engineering of 3D self-directed quantum dot ordering in multilayer InGaAs/GaAs nanostructures by means of flux gas composition
(IOP PUBLISHING LTD, 2008)
Lateral ordering of InGaAs quantum dots on the GaAs (001) surface has been achieved in earlier reports, resembling an anisotropic pattern. In this work, we present a method of breaking the anisotropy of ordered quantum ...
Speciation analysis of inorganic arsenic in river water by Amberlite IRA 910 resin immobilized in a polyacrylamide gel as a selective binding agent for As(v) in diffusive gradient thin film technique
(Royal Soc Chemistry, 2014-09-07)
In this study, a method is proposed for the selective retention of As(v) using diffusive gradient in thin film (DGT) samplers containing a strongly basic anion exchange resin (Amberlite IRA 910) supported on a polyacrylamide ...
Manipulation of emission energy in GaAs/AlGaAs core-shell nanowires with radial heterostructure
(American Institute of Physics - AIPCollege Park, 2014)
Photoluminescence was studied in GaAs/AlGaAs nanowires (NWs) with different radial heterostructures. We demonstrated that manipulation of the emission energy may be achieved by appropriate choice of the shell structure. ...
Arsênio em amostras de sedimento da microbacia do Ribeirão Guamium, Piracicaba, SP e seu efeito em organismos zooplanctônicos
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotec, 2010-09-09)
Arsenic is an essential chemical element for life, although it can be extremely toxic at concentrations slightly above those required for living organisms. In Brazil, generally well-standardized internationally test organisms ...
