Valorização de resíduos agrícolas por compostagem: o caso da laranja

A compostagem é um processo biológico de transformação da matéria orgânica, controlado, aeróbio, desenvolvido sobretudo por microrganismos, que compreende habitualmente um período de temperatura elevada, acima de 45 ºC. A compostagem permite valorizar resíduos orgânicos, em particular de origem agrícola, transformando-os em produtos de elevado valor para melhorar a fertilidade dos solos. As laranjas não comerci...

Application of Dielectric Barrier Discharge (DBD) atmospheric pressure plasma f...

Conventional pretreatment by wet chemistry and/or low-pressure plasma have several drawbacks [1]. Atmospheric plasma is an alternative and cost-competitive method to low-pressure plasma and wet chemical pretreatments, allowing continuous and uniform processing of fibers, substrates and films surfaces, improving its functionalization performance [2]. This technology has been studied in the field of the R&D proje...

Rheologic effect of selected acrylamide reducing agents from plant extracts in ...

Bread is a staple food worldwide with an annual intake recommended by the WHO of 60kg / capita. Strategies to mitigate the occurrence of substances harmful to human health such as acrylamide (AA) should not interfere in food properties perceived by the consumers. The objective of this work was to assess the rheologic (texture and color) effect on two types of bread formulas (wheat and rye) that the addition of ...

Zinc oxide coated optical fiber long period gratings for sensing of volatile or...

The detection of volatile organic compounds is accomplished with a sensing device based on a long period fiber grating (LPFG) coated with a zinc oxide (ZnO) thin layer with self-temperature compensation. The ZnO coating structure was produced onto the cladding of the fiber by thermal oxidation of a metallic Zn thin film. The morphological characterization of ZnO thin films, grown at the same time on silicon sub...

Sensing Structure Based on Surface Plasmon Resonance in Chemically Etched Singl...

Many optical systems based on surface plasmon resonance (SPR) have been developed for working as refractometers, chemical sensors or even for measuring the thickness of metal and dielectric thin films. Sensors based on SPR present very high sensitivity to refractive index (RI) variations when compared to the traditional RI sensors. However, these kinds of systems are usually large, expensive and therefore canno...

Many optical systems based on Surface Plasmon Resonance (SPR) have been developed for work as refractometers, chemical sensors or even for measure the thickness of metal and dielectric thin films. These kinds of systems are usually large, expensive and cannot be used for remote sensing. Optical fiber sensors based on SPR has been widely studied for the last 20 years with several configurations mostly using mult...
