Abstract:
The need for energy and fuels is predicted to grow within the next decades, in parallel to the need of decreasing the emissions to air and water to operate within the planetary boundaries. The alternatives to consider as energy or fuel options need to be environmentally friendly, evaluated over the whole life cycle. Hydrogen is one of the considered alternatives because it contains no carbon and has a good environmental performance when produced from renewable sources. It can be produced by a variety of methods, where electrolyzers have a good potential environmental impact if powered by renew

Abstract:
This master thesis investigated the influence of prefabrication rate of buildings on the embodied environmental impacts. Through a comparative attributional LCA four different Swedish buildings were investigated to explore the influence of PR on the environmental impacts in the categories Cumulative Energy Demand, Global Warming Potential, Water Consumption, Fossil Resource Scarcity, and Mineral Resource Scarcity. The reference buildings had prefabricated rates of 14, 26, 38 and 91%. The results indicate that a higher prefabricated rate (PR) can lead to a lower impact in these categories to so

A wide variety of assessment techniques are presently available to quantify the environmental performance of an organisation. They are predominantly site- or area-specific, making them sensitive to differences in the environmental capacity of an area, and they exclude a number of global impacts.

Furthermore, the generic process data used in these assessment tools, to inform policy decisions on a material or product, does not recognise

Abstract:
La présente thèse aspire à susciter une réflexion profonde et globale tant sur la thématique de l’euthanasie au sens strict, que sur tout l’éventail des décisions médicales prises en fin de vie, en faisant ainsi le tour d’horizon des réglementations nationales européennes et supranationales témoignant de l’intérêt qu’éveille le sujet. Dans cette perspective, ses deux parties abordent la problématique de la mort assistée à travers une approche sensiblement distincte. La démarche comparatiste adoptée dans la première partie tâche d’offrir une vue d’ensemble plus large des solutions envisagées à

REFERAT Övergödning är ett högst reellt hot mot många av Sveriges sjöar och vattendrag och inte minst mot Östersjön. Utsläpp av ej tillräckligt renat avloppsvatten och läckage av näringsämnen från jordbruksmarker är problem som länderna kring Östersjön måste lösa. Sverige arbetar både nationellt och internationellt med att förbättra Östersjöns ekologiska status. Riksdagen har satt upp flera miljökvalitetsmål som bland annat tydliggör att Sverige måste minska tillförseln av näringsämnen till sjöar och vattendrag. Orsaken är att dessa föroreningar är en bidragande orsak till övergödning. Det här

Tristan et Yseut étaient absents du "Lancelot en prose". Le projet du "Tristan en prose" était de surpasser le "Lancelot" en mêlant la légende de Tristan et Yseut et celle du royaume de Logres. Il a pris pour modèles de Tristan et Yseut les amants des "Tristan" en vers, et Lancelot et Guenièvre du "Lancelot en prose". Tristan et Yseut sont une création originale de l'auteur du "Tristan" et non un démarcage de Lancelot et de Guenièvre. Dans le "Tristan", Lancelot et Guenièvre ne sont plus fidèles à ce qu'ils étaient dans le "Lancelot" mais ont été influencés par une éthique nouvelle incarnée pa

Abstract:
Physical education (PE) for pupils with special educational needs (SEN) is an important contemporary issue for primary teachers and other practitioners. In particular, how they are to include pupils with SEN in their classroom activity is a processing concern. This study is concerned essentially with how policy influences the ability of teachers to deal with SEN' pupils in PE. It explores the relationships between education policy on SEN and its implementation within PE when SEN pupils are placed in mainstream school settings. The main aims of this thesis are to explore how 'equality' and 'inc

The research is justified as a tool to assist the manufacturers of transformers industries, utilities and consumers in the choice of material to be used for the manufacture of coils. This research is characterized as a case study, using the NBR ISO 14040:2009 and 14044:2009 methodology. The text is divided into five chapters, the introductory first, second for the literatu

Dans le but d'obtenir une inhibition plus importante de cette voie j’utilise dans ce projet deux nouvelles molécules :- le NVP-BEZ 235 (BEZ) qui inhibe à la fois mTORC1 et la PI3kinase- l'AZD8055 (AZD), un inhibiteur des complexes mTORC1 et mTORC2. En utilisant différentes lignées de LCM, j’ai démontré que l'effet de ces nouveaux inhibiteurs sur la survie cellulaire est plus important que celui du temsirolimus. Cela est probablement dû à l'inhibition de la phosphorylation de l'AKT et la 4EBP. La d

Abstract:
abstract: Healthcare infection control has led to increased utilization of disposable medical devices, which has subsequently led to increased adverse environmental effects attributed to healthcare and its supply chain. In dental practice, the dental bur is a commonly used instrument that can either be reused or used once and then disposed. To evaluate the disparities in environmental impacts of disposable and reusable dental burs, a comparative life cycle assessment (LCA) was performed. The comparative LCA evaluated a reusable dental bur (specifically, a 2.00mm Internal Irrigation Pilot Drill
