Proyectos educativos multidisciplinares y ayuda a la comunidad

2019

This paper relates an experience carried out at a higher education setting, specifically involving 3rd-year students in the Early Childhood Education degree programme. In relation to this, the paper presents an educational model that takes into account the need to develop ethical and social competences and gives importance to interdisciplinary education in real contexts. To this aim, all the academic modules that form part of this degree programme devote 25% of their teaching time and evaluation to the development of an interdisciplinary project. This paper will describe one of these projects, entitled "Solve a real problem", the design of which is informed by service-learning and problem-b…

Multi-intelligence Empowerment in EFL Teaching. The CELSIP Programme for autonomous Learning with Pre-service Teachers

2022

This article presents the design and evaluation processes of a new inclusive and technology-and-autonomous mediated tool named the Communicative English Language Skills Improvement Programme (CELSIP). This project was originally designed to help all kinds of learners to achieve better communicative competencies in English. An empirical mixed-method data collection process was conducted involving 49 students in their fourth year of the Teaching of English in Primary Education Degree. To this end, a semi-structured questionnaire and partipants' one-course-work self-assessment written testimony were analyzed in depth. The findings were significant in that the levels of motivation reported by t…

Ķirurģiskās aprūpes māsas kompetences sejas žokļa ķirurģijas pacientu aprūpē pēcoperācijas periodā

2021

Katrīna Pinkovska. Bakalaura darbs. Ķirurģiskās aprūpes māsas kompetences sejas žokļa ķirurģijas pacientu aprūpē pēcoperācijas periodā. Rīga. Latvijas Universitāte, 2021. Sejas un žokļa ķirurģija mūsdienās tiek uzskatīta par vienu no visgrūtākajām un vispieprasītākajām mūsdienu medicīnas jomām. Lai pacienti saņemtu kvalitatīvu ārstēšanu un aprūpi, liela loma ir māsām. Māsai ir jāspēj ne tikai veikt noteiktas aprūpes darbības, bet arī sniegt atbalstu, palīdzību, uzturēt saskarsmi gan ar pacientu, gan viņa tuviniekiem, motivēt uz ātrāku atlabšanu un izglītot pacientu. Bakalaura darba apjoms ir 39 lpp (neskaitot pielikumus). Bakalaura darbs sastāv no ievada, trīs daļām, pētījuma rezultātu daļa…

Low-temperature Zr mobility: An in-situ synchrotron-radiation XRF study of the effect of radiation damage in zircon on the element release in $H_{2}O…

2006

The release of Zr, U, and Pb from nearly metamict zircon and its recrystallized analog and of Zr from fully crystalline and slightly radiation-damaged zircon in H 2 O + HCl ± SiO 2 fluids was investigated in situ at temperatures between 200 and 500 °C using a hydrothermal diamond-anvil cell and time-resolved synchrotron-radiation XRF analyses. Dissolution of nearly metamict zircon proceeded much faster than that of zircon with little or no radiation damage and resulted in a 1.5 to 2 log units higher Zr molality in 6 to 7 m HCl fluids. Extensive recrystallization of the almost fully amorphous material started at 260 to 300 °C in H 2 O + HCl, and at about 360 °C if quartz was added, and was c…

Solubility and stability of liebigite, Ca2UO2(CO3)3·10H2O(cr), in dilute to concentrated NaCl and NaClO4 solutions at T = 22–80 °C

2019

Abstract The solubility and thermodynamic stability of a synthetic liebigite was investigated in NaCl and NaClO4 solutions within a wide range of ionic strength (0.03 m ≤ Im ≤ 5.61 m), pH (7 ≤ pHm ≤ 9, with pHm = –log [H+]) and temperature (22 °C ≤ T ≤ 80 °C) conditions. A comprehensive characterization of the synthetic solid phase using XRD, quantitative chemical analysis, TG–DTA, SEM–EDS, IR and Raman spectroscopy confirmed the stoichiometry of Ca2UO2(CO3)3·10H2O(cr). At room temperature, liebigite remains stable and controls the solubility of U(VI) in the investigated NaCl and NaClO4 systems with Im ≤ 0.51 m. For the same temperature but high ionic strength (5.61 m NaCl), liebigite trans…

Halloysite nanotubes filled with MgO for paper reinforcement and deacidification

2021

Abstract A novel material for the deacidification and protection of paper has been designed by using MgO filled halloysite nanotubes (Hal). The ability of MgO loaded nanotubes to control the acidic conditions was evaluated by pH measurements in aqueous solvent. Afterwards, paper was impregnated into hydroxypropyl cellulose dispersions containing the consolidating material. A simulation of strong acidic conditions allowed us to evaluate the deacidification effect of the composite material on the samples. In particular, the paper reaches a pH of 7.7 after 1 h exposition to HNO3 vapours when MgO-Hal nanoparticles are added to the impregnation mixture at a concentration of 10 wt% and it remains…

Identification des compétences à l'école élémentaire :une approche empirique à partir des évaluations institutionnelles

2007

Cet article propose une analyse des résultats des élèves aux évaluations nationales, l’objectif étant de mieux comprendre comment les acquisitions se structurent à l’école primaire. L’intérêt de cette démarche réside principalement dans l’identification de compétences dont la maîtrise est essentielle à la réussite scolaire. L’approche choisie pour traiter la question est résolument empirique et se base sur l’examen des relations statistiques entre les items. Elle permet de répondre à plusieurs questions susceptibles d’intéresser les chercheurs en éducation, mais aussi les acteurs engagés, à différents degrés, dans le pilotage et la gestion pédagogique de l’enseignement primaire. Les évaluat…

Sexual advertisement and immune function in an arachnid species (Lycosidae)

2004

A simple version of the immunocompetence handicap hypothesizes that through condition-dependence, the size of the sexual trait may be positively related to immune function at the population level. In the present study, we investigated the relationship between sexual advertisement and immune function in a natural population of male wolf spiders, Hygrolycosa rubrofasciata (Araneae: Lycosidae). Males of H. rubrofasciata have a costly and condition-dependent acoustic signal, courtship drumming. In the mating season, males drum against dry leaves while wandering around the habitat searching for receptive females. Males increase their mating success by increasing their drumming rate and mobility.…

Guenon Radiation is Enriched by a New Species that Demonstrates an Evolutionary Complexity with Which we are yet to Become Familiar

2012

th September described this discovery to the scientific community (1). As is becoming increasingly frequent these days, given the high number of scientific articles, the media news reached us faster than the scientific information. The area known as TL2, a few hundred km as the crow flies south- west from the city of Kisangani, famous for its manufacturing, and important port on the Zaire river, is still uncontaminated and houses several important endemisms. This new species, studied in the area since 2007, on the basis of first sightings by the inhabitants of the zone and local hunters, has been named Cercopithecus lomamiensis. C.lomamiensis (CLO) is a tree-dweller and has been described i…
