        Impurities and Forced Degradation Studies: A Review 

        Universidade Estadual Paulista (UNESP) (Bentham Science Publ Ltd, 2016-01-01)
        The safety of pharmaceuticals is dependent not only on the intrinsic toxicological properties of the active ingredient, but also on the impurities and degradation products that it may contain. The presence of impurities ...

        Impurities and forced degradation studies: A review 

        Universidade Estadual Paulista (UNESP) (2016-01-01)
        The safety of pharmaceuticals is dependent not only on the intrinsic toxicological properties of the active ingredient, but also on the impurities and degradation products that it may contain. The presence of impurities ...

        Influence of the degradation on the stress cracking values of high density polyethylene (HDPE) geomembranes after different exposures 

        Universidade de São Paulo (USP); Universidade Estadual Paulista (UNESP) (2012-12-03)
        This paper presents results from stress cracking (SC) tests performed in both fresh and exposed high density polyethylene (HDPE) geomembranes (GM). The HDPE GMs were exposed to ultraviolet radiation, thermal aging (air ...

        Influence of the degradation on the stress cracking values of high density polyethylene (HDPE) geomembranes after different exposures 

        Lavoie, Fernando Luiz; Bueno, Benedito de Souza; Lodi, Paulo César (2014)

        SnO(2)-based materials for pesticide degradation 

        MALPASS, Geoffroy R. P.; MIWA, Douglas W.; MACHADO, Sergio A. S.; MOTHEO, Artur J. (ELSEVIER SCIENCE BV, 2010)
        This study presents the results of the degradation of the pesticide atrazine using electrochemical and photo-assisted electrochemical degradation techniques using SnO(2)-containing electrode of nominal composition electrodes ...

        Degradation analysis of the SnO2 and ZnO-based varistors using electrostatic force microscopy 

        Universidade Estadual Paulista (UNESP); Universidade Federal de Pernambuco (UFPE) (2013-06-01)
        The degradation phenomena of ZnO and SnO2-based varistors were investigated for two different degradation methods: DC voltage at increased temperature and degradation with 8/20 μs pulsed currents (lightning type). Electrostatic ...

        Vocal responses of austral forest frogs to amplitude and degradation patterns of advertisement calls 

        Penna Varela, Mario; Moreno Gómez, Felipe N.; Muñoz, Matías I.; Cisternas, Javiera (Elsevier, 2017)
        Degradation phenomena affecting animal acoustic signals may provide cues to assess the distance of emitters. Recognition of degraded signals has been extensively demonstrated in birds, and recently studies have also reported ...

        Effect of particle size, iron ligands and anions on ciprofloxacin degradation in zero-valent iron process: application to sewage treatment plant effluent 

        Universidade Estadual Paulista (UNESP) (2017-09-01)
        BACKGROUND: Ciprofloxacin (CIP) is an antibiotic largely used to treat bacterial infections and found in sewage treatment plant (STP) effluent. Zero valent iron (ZVI, Fe0) technology has great potential for the degradation ...

        CONTRERAS,DAVID; OVIEDO,CLAUDIA; VALENZUELA,ROBERTO; FREER,JUANITA; ROJO,KIMENA; RODRÍGUEZ,JAIME (Sociedad Chilena de Química, 2009)

        Using shifts in the electronic emission curve to evaluate polymer surface degradation 

        Universidade de São Paulo (USP); Universidade Estadual Paulista (UNESP) (Elsevier B.V., 2001-01-01)
        The polymer surface degradation and/or modification evolution of Teflon FEP and Mylar C films caused by a low energy electron beam were analyzed using a new method that consists in measuring the second crossover energy ...
