Preparação, caracterização, estudo fotoluminescente e cinético dos complexos de terras raras coordenados a picratos com contra cátions imidazólicos
(Universidade Federal de Minas GeraisUFMG, 2013-01-25)
This work reports the synthesis, characterization and investigation of the photoluminescent properties of pentakis(picrate) complexes of Eu3+, Gd3+, Sm3+, with counter-cations 1-n-butyl-3- methylimidazole (BMIm+), ...
Perfil da suscetibilidade a deltametrina em populações de Triatoma sordida (Hemiptera: Reduviidae) do estado de Minas Gerais procedentes de áreas com infestação persistente
(Universidade Federal de Minas GeraisUFMG, 2012-07-30)
High insecticide resistance ratios on triatominic populations have been frequently reported, causing impact on vector control strategies and challenging scientists and sanitarists on the quest for novel alternatives ...
Efeito da terapia ativa não cirúrgica e da manutenção periodontal em indivíduos com câncer em região de cabeça e pescoço: um estudo prospectivo, controlado e pareado
(Universidade Federal de Minas GeraisUFMG, 2013-06-14)
Studies that investigate the worsening of periodontal disease in patients undergoing radiotherapy for head and neck show increased periodontal attachment loss, which can be explained by a combination of factors such as the ...
Desenvolvimento de curativos para cicatrização de feridas por segunda intenção baseados em biomateriais capazes de promoverem resposta celular controlada via estímulo externo
(Universidade Federal de Minas GeraisUFMG, 2009-06-06)
The high incidence of wound healing by second intention and the high costs associated with their treatment are changing the idea that healing dressing is just for wound protection but to accelerate cell proliferation and ...
Fotocatalizadores heterogêneos magnéticos baseados em óxidos de ferro para produção de hidrogênio via fotólise da água ou para oxidação de compostos orgânicos
(Universidade Federal de Minas GeraisUFMG, 2013-07-05)
This thesis is divided into two major parts: (i) experimental and (ii) theoretical modeling. The experiments can be subdivided into four major parts: (a) Synthesis, characterization and study of the photocatalytic properties ...
Estudo clínico-patológico, imuno-histoquímico e molecular (amplificação do gene MYC) em angiossarcomas e lesões vasculares atípicas da mama
(Universidade Federal de Minas GeraisUFMG, 2014-11-28)
Introduction: Angiosarcomas (AS) of the breast, primary (PAS) or secondary (SAS) to radiotherapy, are rare and aggressive, with significant risk of morbidity and mortality. Atypical vascular lesions (AVL) are vascular ...
Sistema silvipastoril com Urochloa brizantha cv. Marandu e Pterodon emarginatus: sucupira branca
(Universidade Federal de Minas GeraisUFMG, 2014-02-25)
The objective of this work was to observe and describe aspects related to climate, pasture, trees and soil characteristics over a year period of a silvopastoral system with signal grass (Urochloa brizantha) and leguminous ...
Aspectos da função beta da teoria de Yang-Mills supersimétrica
(Universidade Federal de Minas GeraisUFMG, 2012-09-12)
Since the pioneering works there exists a controversy about the origin of the radiative contribuituions to the supersymmetric Yang-Mills beta function. In supersymmetric theories the chiral anomaly and the trace anomaly ...
Aplicações de métodos perturbativos de TQC em modelos de baixa dimensionalidade e matéria condensada
(Universidade Federal de Minas GeraisUFMG, 2014-02-27)
Given the Implicit Regularization's success to separate and analyse spurious arbitrariness, which arise while treating divergent integrals, we proposed to apply this method in three distinct cases. In the rst, we compute ...
Modelagem matemática do resfriamento de tubos em leito contínuo
(Universidade Federal de Minas GeraisUFMG, 2007-04-25)
This work presents a numeric model for the cooling of tubes along a bed of resfriament using the finite volume method. The proposed numeric model considers the gradients of temperature in theaxial, radial and angular ...
