Las interacciones CTSA como oportunidad para la implementación de una propuesta de Aprendizaje-Servicio sobre consumo responsable en Educación Secund…
2022
Desde hace décadas, son numerosas las investigaciones, por parte de especialistas y organismos internacionales, que señalan la necesidad de proporcionar al alumnado una visión global de la actual situación de emergencia planetaria con la finalidad de implicar a las nuevas generaciones en la construcción de sociedades más justas y sostenibles. Este Trabajo de Fin de Máster pretende dar respuesta a estos llamamientos abordando, en particular, las posibilidades que ofrece el currículo de las asignaturas del ámbito científico-tecnológico de Educación Secundaria Obligatoria y Bachillerato para trabajar el impacto socioambiental asociado a la tecnología a partir de las interacciones CTSA, así com…
Ranking of small scale proposals for water system repair using the Rapid Impact Assessment Matrix (RIAM)
2014
Abstract Environmental impacts of small scale projects are often assessed poorly, or not assessed at all. This paper examines the usability of the Rapid Impact Assessment Matrix (RIAM) as a tool to prioritize project proposals for small scale water restoration projects in relation to proposals' potential to improve the environment. The RIAM scoring system was used to assess and rank the proposals based on their environmental impacts, the costs of the projects to repair the harmful impacts, and the size of human population living around the sites. A four-member assessment group (The expert panel) gave the RIAM-scores to the proposals. The assumed impacts of the studied projects at the Easter…
Coauthorship networks and institutional collaboration patterns in reproductive biology.
2007
Objective Reproductive biology is a highly productive area. By analyzing papers published in the major journals in the period 2003–2005, the collaborative patterns were characterized. Design Original research papers published in 2004 in the journals included in the first quartile of the category "Reproductive Biology" of the Journal Citation Reports (2005) were selected. A bibliometric analysis was carried out with the information obtained, thus building up the networks of coauthorship and institutional collaboration. Result(s) A total of 4,702 papers were analyzed, 96.75% signed in collaboration by two or more authors, the authors per paper index being 5.24; 73.73% of the papers were colla…
Ecological study of the wood mouse helminth community in a burned Mediterranean ecosystem in regeneration five years after a wildfire
2007
AbstractParasites are used as biological tags in environmental impact studies. However, terrestrial systems in general and small mammals in particular are rarely considered in these ecological studies. Based on the effects of a wildfire which occurred in the Spanish Serra Calderona Natural Park — a typical Mediterranean ecosystem — the regeneration process of the wood mouse population and its helminth community is analysed. A total of 217 individuals of Apodemus sylvaticus were studied in a five year period, from the second to the fifth post-fire year: 152 mice originating from the burned area and 65 from the control — non-burned — area. The helminth community for both burned and non-burned…
Incidence, severity and orthodontic treatment difficulty index of impacted canines in Saudi population
2018
Background The objective of this study was to assess the incidence, severity and orthodontic treatment difficulty of impacted maxillary canines in Saudi population. Material and methods This retrospective study included an investigation of panoramic radiographs for patients attended College of Dentistry, Jazan University, Saudi Arabia. The incidence of canine impaction and orthodontic treatment difficulty index of maxillary canine impaction was assessed based on; (1) patient age, (2) vertical position, (3) buccolingual position, (4) horizontal position, (5) incisors alignment, (6) canine space, (7) midline coincidence, (8) rotation of impacted tooth. Statistical analyses were calculated by …
Comparative study of the anesthetic efficacy of 4% articaine versus 2% lidocaine in inferior alveolar nerve block during surgical extraction of impac…
2007
Background: A comparative study is made of the anesthetic efficacy of 4% articaine versus 2% lidocaine, both with epinephrine 1:100,000, in truncal block of the inferior alveolar nerve during the surgical extraction of impacted lower third molars. Study design: A randomized double-blind clinical trial was conducted of 30 patients programmed for the bilateral surgical extraction of symmetrical lower third molars in the context of the Master of Oral Surgery and Implantology (University of Barcelona, Barcelona, Spain). Following the obtainment of informed consent, two operators performed surgery on an extemporaneous basis, using as local anesthetic 4% articaine or 2% lidocaine with the same co…
Government Economic Regulations in the Sphere of Higher Education during COVID-19 Crisis in Central Asia
2021
Bakalaura darbā tiek pētīta valsts ekonomiskā iejaukšanās, izmantojot augstākās izglītības ekonomisko regulējumu piemēru Vidusāzijā laikā no 2020. gada marta līdz 2021. gada martam. Mērķis ir salīdzināt COVID-19 krīzes ekonomisko ietekmi uz augstāko izglītību un ieviestajiem ekonomikas noteikumiem. Autors pētījumu veic daļēji strukturētu interviju veidā ar vadošo Vidusāzijas augstskolu pārstāvjiem. Galvenā atklātā problēma ir nesagatavotība ātrai pārejai uz tālmācību. Visbiežākie iemesli ir retā tiešsaistes studiju programmu prakse un sabiedrisko preču, piemēram, stabila interneta pieslēguma un elektrības, nodrošināšana. Pētījums arī parādīja, ka reģionā visplašāk izmantotais regulatīvais r…
Life cycle methods for environmental assessment of nanotechnology
2012
Tämä tutkielma on kirjallisuuskatsaus, joka antaa yleissilmäyksen erilaisiin elinkaarimetodeihin, joilla voidaan arvioida nanoteknologiaa sisältävien tuotteiden ympäristövaikutuksia. Työssä selvitetään elinkaariajattelun tärkeys ja kuvataan erilaisia ympäristöarviointimenetelmiä. Tässä tutkielmassa tarkastellut menetelmät ovat elinkaariarvionti (LCA), hiilijalanjälki, vesijalanjälki, ekologinen jalanjälki ja ekologinen selkäreppu (MIPS). Työ käsittelee nanoteknologiaan liittyviä ympäristöasioita ja tarkastelee elinkaarimenetelmien soveltamista ja soveltuvuutta nanoteknologiaan. Työn tuloksena raportoidaan, että kuvatut ympäristöarviointimenetelmät soveltuvat nanoteknologian vaikutusten arvi…

Review on Life Cycle Assessment of Solar Photovoltaic Panels
2020
The photovoltaic (PV) sector has undergone both major expansion and evolution over the last decades, and currently, the technologies already marketed or still in the laboratory/research phase are numerous and very different. Likewise, in order to assess the energy and environmental impacts of these devices, life cycle assessment (LCA) studies related to these systems are always increasing. The objective of this paper is to summarize and update the current literature of LCA applied to different types of grid-connected PV, as well as to critically analyze the results related to energy and environmental impacts generated during the life cycle of PV technologies, from 1st generation (traditiona…
