Personas mayores en riesgo: uso del preservativo ante las infidelidades
2019
Si bien las infecciones de transmisión sexual suelen relacionarse con etapas evolutivas tempranas, estudios recientes ponen el foco de atención en la población más mayor. Sin embargo, pocos esfuerzos centran su atención en dicho colectivo, entre otros motivos, por la propia invisibilización de su sexualidad. Esto ocurre todavía más, cuando se trata de conductas penalizadas socialmente, como sería el caso de la infidelidad. Por este motivo, el presente estudio busca analizar la conducta de uso del preservativo en personas mayores, en el contexto de la infidelidad, así como el papel que podrían jugar variables psicológicas y nuevos contextos sexuales, como internet. Para ello, 244 personas (4…
Metaphorical dimension of idioms in TV series for German, Norwegian and Spanish audiences
2022
Over recent years, internet TV series have grown in popularity to become one of the audiovisual products with the highest audiences worldwide. The Covid crisis, with limitations on movement, has further increased their success during 2020-21. English is by far the most common language for such productions, which are typically offered to non-anglophone viewers in translated format, with either subtitles or dubbing. One of the main challenges in translation here concerns the use of idioms, since these do not always have a fixed equivalent in the target language. Taking as a starting point a corpus of drama series from Netflix and Amazon Prime, this study considers the metaphorical dimension o…
The role of lexical aspect in constructing Proto-Indo-European verbal paradigms
2009
The aim of this paper is to recover the role of the [± telic] inherent feature of PIE verbal roots, regardless of the many different meanings which derived verbs could take depending on their combination with arguments, adverbials, and so on. Semantic changes due to different contexts could have indeed obscured the relationship between the original lexical aspect of a verb and the structure of its morphological paradigm. The aspectual class is often described as a compositional property, and verbs are even analyzed as complex structures made up of completely neutral roots without any information about their argument structure. However, the distribution and the kind of forms within the parad…
Promotion of Literacy in Sub-Saharan Africa: Goals and Prospects of CAPOLSA at the University of Zambia
2014
The convergence of two complementary agendas motivated collaboration between two universities (in Zambia and Finland) to establish the Centre for the Promotion of Literacy in Sub-Saharan Africa (CAPOLSA), focused on initial literacy learning in indigenous languages. The project’s mandate and activities are closely related to Zambia’s national context of literacy and educational provision, emerging trends in information and communication technology, and the University of Zambia’s institutional context of research and development on literacy, child development, and education. CAPOLSA has afforded opportunities for enhancing the working relations between the national university and government …
La street art come motore di recupero e rigenerazione urbana delle aree interne. Un progetto condiviso per lo sviluppo di smart villages nell'area Ma…
2022
The Madonie district, one of the 72 pilot areas of the National Strategy for Inner Areas in Italy in the center of Sicily, is composed by 21 municipalities that really have a great potential, due to their historical background and natural landscape, but it needs new strategies to emerge. Many people from northern cities have returned to their home villages in recent years, to live and work, but they have not found some important and necessary services as there are in smart cities, and to date, these villages do not adopt smart strategies. Many changes need to be made, one solution is to transform them into smart villages through rehabilitation, such as improving the historic center with str…
Proposal of a Modelling of the Innovation Process in an International Manufacturing Company
2017
Nowadays, to cope with the competition, and to ensure the durability of their activities, companies have to be able to innovate. Manufacturing companies operating in a B2B market often perceive innovation as a technological result. However, innovation is often more characterized as a process. The needs of the users, and not only the technology, can achieve innovation. In this context, our paper intends to determine how to involve better the users in the innovation process of an international manufacturing company, which is, according to us, representative of the current manufacturing companies. The aim of our research paper is to help manufacturing companies to manage innovation led by user…
Plasma selenium levels and oxidative stress biomarkers: a gene-environment interaction population-based study.
2014
The role of selenium exposure in preventing chronic disease is controversial, especially in selenium-repleted populations. At high concentrations, selenium exposure may increase oxidative stress. Studies evaluating the interaction of genetic variation in genes involved in oxidative stress pathways and selenium are scarce. We evaluated the cross-sectional association of plasma selenium concentrations with oxidative stress levels, measured as oxidized to reduced glutathione ratio (GSSG/GSH), malondialdehyde (MDA), and 8-oxo-7,8-dihydroguanine (8-oxo-dG) in urine, and the interacting role of genetic variation in oxidative stress candidate genes, in a representative sample of 1445 men and women…
Correlations of blood selenium with hematological parameters in West German adults.
1988
The serum selenium and the whole blood selenium of 72 healthy persons (47 women, 25 men) was determined. There exist sex specific differences of the whole blood selenium between men (98 +/- 19 micrograms Se/L) and women (89 +/- 17 micrograms Se/L). The serum selenium did not show sex specific differences, but sex specific differences are found if the total amount of extracellular selenium is calculated by correction of the serum selenium with the hematocrit. Women have more extra-cellular selenium/L whole blood (40 +/- 8 micrograms Se) than men (36 +/- 7 micrograms Se). Men have more intraerythrocyte selenium (cellular selenium = 67 +/- 14 micrograms Se) in one L whole blood than women (52 …
Uranium speciation in plants
2002
The chemical characterization of the radionuclide species is essential for a reliable assessment of the migration of radionuclides and heavy metals into the geological and biological environment on the load pathway soil - plant - animal - human. Only a few is known about the speciation of uranium in plants. Therefore we investigate the change of speciation during the transfer of uranium from initial solution into plant. Various plants (lupins, dandelion e.g.) were grown in an agricultural test field and in the laboratory on contaminated soils (up to concentration of 1g U/kg soil) and as hydroponics in the uranium containing solutions (uranium concentration: 10-5 M - 10-2 M, pH: 3 - 8). For …
Lignin-based activated carbon-supported metal oxide catalysts in lactic acid production from glucose
2021
Abstract In this study, heterogeneous biomass-based activated carbon-supported metal oxide catalysts were prepared and tested for lactic acid production from glucose in aqueous solution. Activated carbons were produced from hydrolysis lignin by chemical (ZnCl2) or steam activation and modified with a nitric acid treatment and Sn, Al, and Cr chlorides to obtain carbon-based metal oxide catalysts. The modification of the carbon support by nitric acid treatment together with Sn and Al oxides led to an increase in lactic acid yield. The highest lactic acid yield (42 %) was obtained after 20 min at 180 °C with the Sn/Al (5/2.5 wt.%) catalyst on steam-activated carbon treated by nitric acid. Reus…
