Este trabalho descreve o desenvolvimento de uma metodologia para a pré-concentração seletiva de Cu(II) usando espuma de poliuretano (PUF) como suporte e o negro de eriocromo T (EBT) como ligante. A extração quantitativa do Cu(II) foi obtida em um meio contendo 60 mg L de EBT e pH 1,5 (ajustado com solução de HCl). O tempo mínimo para extração do Cu(II) foi de 30 min quando 200 mg de PUF foram a...
We clarify a discrepancy between two previous calculations of the two-loop QED Euler-Heisenberg Lagrangian, both performed in proper-time regularization, by calculating this quantity in dimensional regularization. e-mail address D.FliegnerThPhys.Uni-Heidelberg.De e-mail address M.G.SchmidtThPhys.Uni-Heidelberg.De e-mail address [email protected] Supported by Deutsche Forschungsg...
X-ray computed tomography is an imaging method which makes tomographic images with high contrast and resolution. However, CT-scans deliver much more radiation dose compared with other imaging techniques. The aim of this study was to evaluate two-dimensional dose distribution in a PMMA phantom as well as investigationof the effect ofcollimation factor on the dose distribution measuredusing GAF-C...
This chapter provides an overview of the evidence-based treatment (EBT) paradigm, beginning with definitional issues, followed by a discussion on use of the iterative process and the importance of strong academic-practice partnerships to inform the development, selection, and implementation of EBTs.The discussion then turns to the importance of attaining, measuring, and sustaining fidelity to t...
The "Evidence-based Telemedicine - Trauma & Acute Care Surgery" (EBT-TACS) Journal Club performed a critical review of the literature and selected three up-to-date articles on the management of splenic trauma. Our focus was on high-grade splenic injuries, defined as AAST injury grade III-V. The first paper was an update of the 2003 Eastern Association for the Surgery of Trauma (EAST) practice m...
Recently, utilization of biological adsorbents plays an important role in the removal toxic dyes such as Eriochrome Black T (EBT) azo-dye they are considered being produced from natural renewable source, easy availability, low cost, and environmentally friendly. In this study, vermicompost (VC) was utilized to remove aqueous solution along ultrasonic ultrasonic-assisted adsorption. The paramete...
