Stability of clavulanic acid under variable pH, ionic strength and temperature conditions. A new kinetic approach
(ELSEVIER SCIENCE SA, 2009)
Clavulanic acid (CA) is a beta-lactam antibiotic that alone exhibits only weak antibacterial activity, but is a potent inhibitor of beta-lactamases enzymes. For this reason it is used as a therapeutic in conjunction with ...
Desenvolvimento de um núcleo versátil e integrado de ferramentas CAD/CAE para a modelagem e simulação de peças mecânicas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2012-03-05)
Currently there is still a high demand for quality control in manufacturing processes of mechanical parts. This keeps alive the need for the inspection activity of final products ranging from dimensional analysis to chemical ...
Homogeneous Biocatalysis in Organic Solvents and Water-Organic Mixtures
(Taylor & Francis, 2003-12)
Biocatalysis in non-aqueous media has undergone tremendous development during the last decade, and numerous reactions have been introduced and optimized for synthetic applications. In contrast to aqueous enzymology, ...
Analysis of reverse heat transfer for conventional and optimized lubri-cooling methods during tangential surface grinding of ABNT 1020 steel
(Fundação Gorceix, 2016-12-01)
Abstract A numerical thermal model was developed to evaluate the heat flux which is conducted to a rectangular workpiece of steel plate ABNT 1020, thus making it possible to compute the maximum temperature in the grinding ...
The use of two non-toxic lipophilic oils to generate environmentally friendly anionic reverse micelles without cosurfactant. Comparison with the behavior found for traditional organic non-polar solvents
(Elsevier Science, 2014-03)
In this work two different non-toxic solvents/sodium 1,4-bis-2-ethylhexylsulfosuccinate (AOT)/water reverse micelles (RMs) have been investigated by dynamic (DLS) and static (SLS) light scattering techniques. Methyl laurate ...
Engenharia reversa: um método orientado a imobilizadores ortopédicos
(Universidade Estadual Paulista (UNESP), 2016-12-07)
Na área da ortopedia a busca por novos avanços tecnológicos tem sido muito pouco e as pessoas que necessitam de dispositivos como órteses acabam sofrendo mais devido ao alto custo dos aparelhos ortopédicos. A maioria da ...
