We're Chained: an analysis of systemic risk in finance
(2015-08-14)
This dissertation presents two papers on how to deal with simple systemic risk measures to assess portfolio risk characteristics. The first paper deals with the Granger-causation of systemic risk indicators based in ...
Comparison of three different sample preparation procedures for the determination of traffic-related elements in airborne particulate matter collected on glass fiber filters
(2012)
Three different procedures for sample preparation have been compared for the determination of Cu, Mo and Sb in airborne particulate matter (APM) collected on glass fiber filters using high-resolution continuum source ...
Direct determination of arsenic in petroleum derivatives by graphite furnace atomic absorption spectrometry: A comparison between filter and platform atomizers
(2011)
In the present work a direct method for the determination of arsenic in petroleum derivatives has been developed, comparing the performance of a commercial transversely heated platform atomizer (THPA) with that of a ...
Development of a filter for phycocyanin bio-optical estimation
(2014-01-01)
Phycocyanin is a unique pigment for cyanobacteria in inland waters which has been identified by remote sensing. Several band ratio algorithms were developed to estimate and identify phycocyanin using its absorption spectral ...
Transparent polysilsesquioxane films obtained from bridged ureasil precursors: Tunable photoluminescence emission in the visible region and filtering of UV-radiation
(Wiley VCH Verlag, 2010-11)
Bridged ureasil precursors were synthesized by the reaction of either ethylenediamine (1 mol) or m-xylylenediamine (1 mol) with isocyanatepropyltriethoxysilane (2 mol). Transparent polysilsesquioxane films were obtained ...
Silica–Calcareous Non Fired Bricks Made of Biomass Ash and Dust Filter from Gases Purification
From the point of view of saving and conservation of natural resources, the use of alternative components in construction materials is now an international concern. In this work, the valorization of two industrial wastes ...
Associação do filtro orgânico butil metoxi dibenzoil metano com o sistema óxido de zinco: óxido de titâmio (IV) para aplicação em protetores solares
(Universidade Estadual Paulista (Unesp), 2010-12-20)
A preocupação com a radiação ultra-violeta (UV) do espectro eletromagnético que atinge a superfície terrestre, devido ao aumento do índice de câncer de pele, tem incentivado a pesquisa de produtos para a proteção da pele. ...

Broad spectrum bioactive sunscreens
(ELSEVIER SCIENCE BV, 2008)
The development of sunscreens containing reduced concentration of chemical UV filters, even though, possessing broad spectrum effectiveness with the use of natural raw materials that improve and infer UV absorption is of ...
Estudo do potencial de associações de ZnO com os produtos naturais ácido cafeico e ferúlico como filtros solares híbridos: [recurso eletrônico]
(Universidade Estadual Paulista (Unesp), 2009)
In this work were studied associations of ZnO with the natural products caffeic and feluric acids. Two preparation methods were used, that is, the sol-gel and a reflux procedure. In the sol-gel method, ZnO is produced by ...
