Planejamento experimental aplicado aos estudos de degradação forçada do fármaco Ticagrelor
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2020-08-31)
Stability indicating tests are an essential part during pharmaceutical drug production, besides being a mandatory step for the regulation and approval from the regulatory agencies. Forced degradation consist of an exposure ...
Effect of lubricant degradation on the tribological performance of a wheel-rail system
(2014-09-08)
Abstrac: In this work lubricant degradation and its relationship with tribological behavior was studied. Commercial grease (Sintono Terra HLK) and three versions of a newly developed product (Tribolub) for the Metro system ...
Avaliação da cinética de degradação abiótica do polietileno de alta densidade, na presença e ausência de aditivo pró-degradante e estabilizantes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2016-11-28)
The convenience of single-use packaging of high density polyethylene (HDPE) led to the need to convert them into biodegradable materials in less time to minimize the environmental problems caused by disposal. An alternative ...
Influência de aditivos pró-degradantes nas degradações abiótica e biótica do polietileno de alta densidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2015-03-06)
High density polyethylene (HDPE) is widely used in the manufacture of
packaging disposables and in order to minimize the environmental impact
caused by disposal, have been incorporated, into the HDPE, additives that
promises ...
Degradation modeling for reliability analysis with time-dependent structure based on the inverse gaussian distribution
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2017-04-07)
Conventional reliability analysis techniques are focused on the occurrence of failures over
time. However, in certain situations where the occurrence of failures is tiny or almost null, the
estimation of the quantities ...
Degradação forçada dos fármacos nitazoxanida e sofosbuvir e degradação térmica de dispersões sólidas amorfas contendo ritonavir
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2022-04-28)
The first chapter of this work aimed to use design of experiments in the forced degradation of sofosbuvir (SOF) and nitazoxanide (NTZ). The variables pH, temperature and interaction between temperature and H2O2 contributed ...
Deconvolução de espectros UV diretamente de soluções de degradação forçada de fármacos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2022-04-27)
Forced degradation studies (EDFs) are assays which pharmaceuticals are placed under stress conditions, which include acidic, basic, oxidative, high temperature, photodegradation, humidity and metal ions environments. The ...
