In vitro comparison of the force degradation of orthodontic intramural elastic from different compositions
(2013)
Introduction and Objective: The synthetic intermaxillary elastic emerged as an alternative for clinical use in patients with latex sensitivity. However, there are disagreements about this elastic protocol use according to ...
Characterization of ZnO-degraded varistors used in high-tension devices
(Elsevier B.V., 2007-06-05)
The effects of the degradation process on the structural, microstructural and electrical properties of ZnO-based varistors were analyzed. Rietveld refinement showed that the BiO2-x phase is affected by the degradation ...
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 ...
Modeling the dynamics of failure of the electric shield at the renal glomerulus
(Institute of Electrical and Electronics Engineers Inc., 2017-08)
The human kidney can be seriously threated in the cases where the presence of bunches of electric charges may cancel its electric shield that plays the protectionist role against the pass of giant proteins through the ...
In vitro comparison of the force degradation of orthodontic intraoral elastics from different compositions
(2013)
The synthetic intermaxillary elastic emerged as an alternative for clinical use in patients with latex sensitivity. However, there are disagreements about this elastic protocol use according to the force degradation. The ...
Modeling the electric degradation of podocytes and detection of albumin for the early diagnostics of the glomerulus's damage
(Institute of Electrical and Electronics Engineers Inc., 2017-05)
In this paper, the pass of proteins like the albumin through the glomerular layers is modeled. Mainly, we have focused on the mathematical model based on physics which might explain the filtering of giant proteins like the ...
Investigação e elucidação estrutural por LC-MS/MS e RMN ¹H de impurezas desconhecidas de Ramipril Pellet geradas em estudo de degradação forçada
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação de Mestrado Profissional em Química - PPGQCâmpus São Carlos, 2018-07-27)
The development of a pharmaceutical product comprises multidisciplinary steps, coming from compatibility studies between the active pharmaceutical ingredient (API) and the other raw material (excipients) to studies of ...
