Context. Global software development (GSD) gained huge recognition in today’s business world. Most of the software companies day by day are striving hard to evolve globally where software is developed in the context of different environmental settings that are distanced on various factors like geography, timezone, culture and language. Coordination is the factor that plays one of the prominent roles in such a setting for effective teamwork and project success. Although numerous efforts has been done in this research area, there has been no proper evidence from industry about the impact of thes

Population ageing is one of the major challenges of the 21st century and societies need to optimize opportunities for active ageing. This thesis explored how the built environment impacts the mobility and participation within the community. A combination of person-based GPS tracking and in-depth interviews was used to collect data on transportation use and engagement in activities of older people living within Brisbane. It showed that the built environment has a strong impact on mobility. To enable healthy and active ageing modern communities need to overcome car dependency and provide mobilit

Abstract:

The United Nations recognises anthropocentric greenhouse gas emissions to be the leading cause of global warming. The International Institute of Refrigeration further addresses that in 2014 7.8% of the global greenhouse gas emissions were assigned to the refrigeration sector. This marked the importance of using metrics to evaluate the climate impact of a refrigeration system. However, as these metrics rely on uncertain values it is difficult to assess how reliable they are. The purpose of this study is therefore to evaluate the reliability of two environmental metrics by applying methods for d

Trucks are used to transport goods and services using road transportation. Emissions from the transportation industry are rising with every passing year.

New technologies in the field of transportation are coming to the market every year. It is important to evaluate the impacts from these technologies to support the 2030 agenda of Swedish government.

Abstract:

Packaging plays a crucial role in logistics as it has a significant effect on the efficiency of transportation. The shape and dimensions of packaging material has considerable impact on transport performance, whereas an optimal packaging system for products enables for improved utilization of the total volume on a load carrier. As a result of improved freight performance, transportation costs can be reduced. Improved vehicle utilization for shipments also has a positive impact on environmental aspects, as increased vehicle fill rate can lead to less required transports which ultimately lowers

Досліджено кількість та тривалість тропічних ночей у Сумах за період з 2005 по 2021 рік. За цей час було зафіксовано 113 тропічних ночей, у середньому 7,06 на рік. Тропічні ночі були зафіксовані в травні, червні, липні, серпні та вересні. Місяцем з найбільшою зареєстрованою кількістю тропічних ночей є липень − загалом 46 випадків, за ним слідує червень із 35 випадками, 28 тропічних ночей було зафіксовано в серпні, 3 тропічні ночі були в травні та одна у вересні 2020 року.<br>Исследованы количество и продолжительность тропических ночей в Сумах за период с 2005 по 2021 год.

Abstract:

A revolução tecnológica, as mudanças na estrutura competitiva da economia mundial e as necessidades financeiras motivaram vários países a realizar transformações estruturais no setor de telecomunicações. Essas mudanças incluíram a liberalização progressiva do setor, o estabelecimento de um órgão regulador e a privatização. Neste contexto, as empresas passaram a competir intensamente e buscar competências essenciais ao negócio. Esta busca quando realizada de forma isolada passou a exigir elevado esforço por parte das empresas. Com isso, o estabelecimento de alianças e redes na obtenção de vanta

Abstract:

This thesis assessed the life-cycle environmental impact of a lithium-ion battery pack intended for energy storage applications. A model of the battery pack was made in the life-cycle assessment-tool, openLCA. The environmental impact assessment was conducted with the life-cycle impact assessment methods recommended in the Batteries Product Environmental Footprint Category Rules adopted by the European Commission (2016). The findings in this study showed that the most important parameter in the cradle-to-grave assessment was the use-stage losses, which can be reduced by using electricity grids

Abstract:

Dans un contexte de changements globaux, la fonction de "puits" de carbone (C) des tourbières est susceptible de basculer vers une fonction "source", en libérant dans l'atmosphère de grandes quantités de C initialement stockées dans la tourbe. Cette thèse vise à caractériser et quantifier, à différents niveaux d'organisation, i) l'impact d'un réchauffement climatique sur le fonctionnement biogéochimique (C-N-S) d'une tourbière à Sphaignes et ii) l'impact de la restauration d'une tourbière abandonnée après exploitation sur les interactions entre les plantes recolonisatrices (Eriophorum angustif

Abstract:

Although the dynamics of methane (CH4) emission from croplands and wetlands have been fairly well investigated, the contribution of trees to global methane emission and the mechanisms of tree transport are relatively unknown. Methane emissions from the common wetland tree species Populus trichocarpa (black cottonwood) native to the Pacific Northwest were measured under hydroponic conditions in order to separate plant transport mechanisms from the influence of soil processes. Roots were exposed to methane enriched water and canopy emissions of methane were measured using a canopy enclosure. Met

Abstract:

Malgré leur empreinte géographique limitée (3% de la surface terrestre), les tourbières à sphaignes de l'hémisphère Nord renferment 1/3 du stock de carbone (C) des sols mondiaux. La forte accumulation de C n'est pas due à une forte production végétale primaire nette, mais à une faible décomposition de la matière organique (MO) intrinsèquement dépendante de communautés biologiques et de conditions environnementales et climatiques très spécifiques (engorgement, anoxie, oligotrophie, acidité, faible température) constituant ainsi des facteurs limitants de l'activité microbienne.

Syftet med denna uppsats har varit att genom en litteraturgranskning ta reda på vilket material av trä eller betong för byggnader i Sverige som resulterar i minst utsläpp av koldioxidekvivalenter. Bygg-och fastighetssektorn bidrar till 10-30% av Sveriges totala miljöpåverkan och enligt Boverket så har denna verksamhet dessutom ökat andelen koldioxidutsläpp under de senaste åren. Denna studie har utförts som en så kallad rapid review med en tillhörande kvalitetsbedömning av aktuella artiklar.

Abstract:

L'objectif principal de ce travail était d'étudier le devenir biogéochimique du matériel organique particulaire du Rhône, et les mécanismes impliqués dans le cycle du carbone au niveau de son delta. L'utilisation de microélectrodes in situ a permis l'obtention de profils haute résolution d'oxygène dans les sédiments et l'estimation du recyclage sédimentaire. Il apparait que la variabilité saisonnière des apports rhodaniens tant qualitative que quantitative influence l'activité de minéralisation benthique dans le delta du Rhône. Cependant, l'impact de ces apports pulsés est limité dans le temps

Pour la climatisation de bâtiments ou d'installations industrielles, les nappes d'eaux superficielles représentent une source de frigories très convoitée. Leurs exploitations intensives depuis plusieurs dizaines d'années conjuguées au redéploiement de la filière géothermique ces dernières années, soulèvent des préoccupations quant à la préservation des ressources en eau. Dans ce contexte, la présente étude vise à évaluer l'impact de variations locales de température sur la qualité physico-chimique et microbiologique des eaux souterraines sur la base (i) de suivis in-situ au niveau de 3 install

Projektionen der Effekte von Umweltveränderungen auf sozio-ökologische Systeme sind ein fester Bestandteil der Nachhaltigkeitsforschung. Solche Projektionen beruhen auf Modellen und Modellketten. In jedem Modellierungsschritt werden modelspezifische Unsicherheiten bezüglich Parameterwerten, Eingabedaten und Modelstruktur akkumuliert und führen zu einer Kaskade der Unsicherheiten. Ziel dieser Dissertation ist es, die Kaskade der Unsicherheiten der Wirkungen von Umweltveränderungen am Beispiel der Waldökosystemmodellierung zu behandeln.
