Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments

2013

Author's version of an article in the journal: Chemical Engineering Science. Also available from the publisher at: http://dx.doi.org/10.1016/j.ces.2012.11.028 A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical models have been proposed to try to predict the design loads for such shallow silo hoppers to guarantee their structural integrity. In this study, a novel finite element analysis has been conducted to explore the development of pressures and tractions on the wall of a full scale shallow hopper when it is filled wit…

Protons for Jehovah’s Witnesses? How press coverage of Ashya King’s case brought proton beam therapy to the public arena

2018

The case of Ashya King, the child brain tumour patient whose parents took from a British hospital so he could be treated with Proton Beam Therapy (PBT) abroad, contributed to popularize that technology among a general audience. Through the content analysis of British and Spanish press coverage (N=329), our research shows that proton therapy enjoyed scarce coverage in the analysed media before Ashya King’s case. His story, magnified due to the fact that his parents were Jehovah’s witnesses was a cause both for public concern and media sensationalism. We show that the case brought PBT into the public sphere and, consequently, contributed to create a demand for facilities that offered this the…

D. Álvaro d’Ors, foralista, y el derecho foral valenciano

2016

espanolUna de las facetas mas caracteristicas de Alvaro d’Ors es su interes por el derecho foral. En este trabajo se resenan sus principales contribuciones en especial aquella en la que contesta a la tajante negacion de Federico de Castro de la existencia de derechos forales. Desde la perspectiva orsiana los derechos forales no obedecen a una razon de privilegio sino de subsistencia con lo que ello implica de realidad social. El autor utiliza las tesis orsianas para hacer referencia al derecho foral valenciano. EnglishOne of the most characteristic facets of Alvaro d'Ors is his interest in regional law. This paper highlights his main contributions, especially that in which he answers to the…

Metaforu lietojums ziņu rakstos par 2016. gada ASV prezidenta vēlēšanām

2017

Bakalaura darbs ir veltīts metaforu lietojuma izmeklēšanai divu ASV laikrakstu (The Wall Street Journal un The New York Times) interneta vietnēs. Pētījums analizē konceptuālās metaforas lietojumu ziņu rakstos par 2016. ASV prezidenta vēlēšanām. Pētījuma mērķis ir izmeklēt konceptuālo metaforu nozīmi ASV prezidenta vēlēšanu konceptualizācijā. Pielietotā metode ir konceptuālo metaforu analīze. Apkopotie dati ļauj secināt, ka analizētajos rakstos koncetuālajām metaforām ir būtiska nozīme vēstījuma veidošanā.

Äitien pyrkimykset ja toimintamahdollisuuksien valikko : käsitteellinen tutkimus äitien taloudellisista toimintamahdollisuuksista

2018

This study addresses the conceptual outlines of the financial capabilities of moth- ers. It examines how the perspectives and concepts of the capability approach can be utilized in outlining the relationship between motherhood and financial aspects. The aim is to develop conceptual tools for analyzing the choices and financial agency of mothers. This study emphasizes the methodological dimension using three elements: the capability approach, feminist economics and memory work. The main element of the study is the capability approach, which provides the perspective of the inquiry and the concepts for analysis. Feminist economics provides a definition of economy and a way to produce knowledge…

Sulfate sensitivity of aquatic organism in soft freshwaters explored by toxicity tests and species sensitivity distribution

2023

Elevated concentrations of sulfate in waterways are observed due to various anthropogenic activities. Elevated levels of sulfate can have harmful effects on aquatic life in freshwaters: sulfate can cause osmotic stress or specific ion toxicity in aquatic organisms, especially in soft waters where Ca2+ and Mg2+ concentrations are low. Formerly, chronic toxicity test data in soft water have been scarce. The chronic and acute sulfate toxicity tests conducted with aquatic organisms from 10 families across various trophic levels in this study multiplied the number of tests conducted in soft freshwater conditions and enabled derivation of the species sensitivity distribution (SSD) and sulfate haz…

Effect of oxidoreduction potential and of gas bubbling on rheological properties and microstructure of acid skim milk gels acidified with glucono-del…

2009

Milk oxidoreduction potential was modified using gases during the production of a model dairy product and its effect on gel setting was studied. Acidification by glucono-delta-lactone was used to examine the physicochemistry of gelation and to avoid variations due to microorganisms sensitive to oxidoreduction potential. Four conditions of oxidoreduction potential were applied to milk: milk was gassed with air, nongassed, gassed with N(2), or gassed with N(2)H(2). The rheological properties and microstructure of these gels were determined using viscoelasticimetry, measurement of whey separation, and confocal laser scanning microscopy. It appeared that a reducing environment led to less-aggre…

Influence of low methoxyl pectin gel textures and in vitro release of rutin from calcium pectinate beads.

2013

This study described the preparation and characterization of low methoxyl pectin (LMP) gels and beads for controlled release applications. The rheological characterization of the various formulations was proposed. Then the mechanical and morphological characterizations of beads were determined. Finally, the controlled release studies taking rutin as a model drug was evaluated. The results showed that Young's modulus values of non-amidated LMP gels decrease when adding up to 15% sorbitol. Calcium pectinate beads loaded with rutin are about 600 μm, oblong shaped with dense matrix. Beads containing sodium bicarbonate showed about 80% lower rutin encapsulation efficiency by increasing the pH of…
