Micro-Raman and SEM-EDS analyses to evaluate the nature of salt clusters present in secondary marine aerosol
(Elsevier, 2017-10-17)
Marine aerosol is a complex inorganic and organic chemistry system which contains several salts, mainly forming different type of salt clusters. Different meteorological parameters have a key role in the formation of these ...
Microparasitic disease dynamics in benthic suspension feeders: Infective dose, non-focal hosts, and particle diffusion
(Elsevier, 2016-03-05)
Benthic suspension-feeders can accumulate substantial numbers of microparasitic pathogens by contacting or filtering particles while feeding, thus making them highly vulnerable to infectious diseases. The study of disease ...
Raman spectroscopy assisted with XRF and chemical simulation to assess the synergic impacts of guardrails and traffic pollutants on urban soils
(Wiley, 2012-11-01)
Urban soils are potential reservoirs of toxic metals as a consequence of traffic emissions. Sources like brake linings, tyres, road pavement, exhaust fumes, guardrail, traffic signals and other galvanised steel structures ...
Electrochemical behavior of metal-supported SOFCs under high fuel utilization and their durability
(ASME, 2012)
The aim of this project was to study whether the oxidation resistance of cells is affected while working under high fuel utilization. A previous study measured the weak oxidation resistance for very porous samples (measured ...
Morphological study and photo-addressing in poly(styrene-b-butadiene-b-styrene) block copolymers with azobenzene groups and polystyrene matrix: influence of chemical bonding
(2011-01-25)
The main goal of this work was the synthesis of new azo-functionalized block copolymers
(BCP) from epoxidized poly(styrene-b-butadiene-b-styrene) modified with azobenzene
groups by one-step facile reaction between the ...
Reversible optical storage properties of nanostructured epoxy-based thermosets modified with azobenzene units
(ACS, 2011-11-22)
Azo-containing polymers are of particular interest in the design of materials for applications in optical recording. The aim of this contribution was the synthesis and characterization of optically active epoxy-based ...
Multi-GGS-groups have the congruence subgroup property
(Cambridge University Press, 2019-02-21)
We generalize the result about the congruence subgroup property for GGS-groups to the family of multi-GGS-groups; that is, all multi-GGS-groups except the one defined by the constant vector have the congruence subgroup ...
Multistage treatment of almonds waste biomass: characterization and assessment of the potential applications of raw material and products
(Elsevier, 2018-09-06)
Almond shells are waste biomass generated in agro-industrial activities, which represent a resource that can be further valorized upon treatment. The purpose of this work was to assess new value-added products obtained ...
Non-financial reports, anti-corruption performance and corporate reputation
(Fundação Escola de Comércio Álvares Penteado, 2015)
Objective – This paper analyzes whether the anti-corruption reporting practices of the companies are a reflection of adequate anti-corruption systems put in place by companies, or whether the disclosure is merely a tool ...
Nursing students’ misunderstandings when learning about stroke care: A phenomenographic study
(Elsevier, 2019-02)
Background: Considering the prevalence and complexity of a stroke, it is necessary to think about how undergraduate nursing students are developing knowledge for stroke care.
Aim: To obtain a vision of nursing students’ ...
