Over the past 150 years, industrialization, globalization and population growth have altered the planet and its natural conditions at a rapid pace. In this new era, the Anthropocene, environmental degradation has come to a state where sustainable ecosystem management has developed into an urgent quest for humans to maintain their own life-support system. The ecosystem services (ES) concept, initia

Context Background Globalisation, increasing product complexity, volatile demand, and financial crisis all put strains on the supply, processing, and distribution of goods. That’s why supply chain management has become the area to focus on to gain competitive advantages and reduce costs. Saint-Gobain Sekurit Scandinavia (SGSS) is part of a large global French enterprise, Saint-Gobain that’s a worl

Populärvetenskaplig sammanftaaning: För 65 miljoner år sedan slog en extraterrestrisk kropp ner på Yucatán-halvön i södra Mexico. Nedslaget orsakade ett av de största massutdöendena i historien, då bland annat dinosaurierna dog ut. Nedslaget kan ha varit en följd av ett tillfälligt ökat asteroidflöde i inre solsystemet som orsakats av att en jätteasteroid i asteroidbältet mellan Mars och Jupiter bAn impact crater is the result of a collision between a large and a smaller body. On Earth most of the cratering record has been erased because of tectonic processes and weathering. The Moon, however, displays a nearly complete record of impact events over the last 2 Gyr, and evidence of impact cratering events nearly 4 billion years old. The same family of impactors is responsible for the formati

Abstract The pharmaceutical industry is currently facing a high clinical attrition rate. In order to prevent the late-stage clinical failure, many investigations on compound quality and drug-likeness of compounds have been carried out. It has been widely accepted that molecular size and lipophilicity plays an important role in compound quality. Many attempts have been done to find out other fact

This study deals with the acquisition of negation in French second language for Swedish speakers in written production. In fact, numerous studies have been dedicated to this subject, investigating learners with different first languages. However, these studies often examine the acquisition of negation in oral language. Given the difference between speaking and writing in French language, it is als

Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. The aim of PEF is to provoke electroporation to the membranes of the plant cells, thereby allowing the cryoprotective solution impregnated by VI to penetrate the cells. PEF

Scalability, pay-as-you-go, and flexibility are some factors why more and more organizations are utilizing a cloud environment for their IT systems. Specifically, the trend is towards multi-cloud, where different cloud providers manage different applications and services. This environment is however a lot less deterministic than an on premise solution. For example, if an application from one cloud

Methodology: The thesis applies a single case study design to examine an opening up process in relation to open innovation. The thesis used a qualitative research strategy with inductive design with influences of deduction. The primary data emerged from semi-structured interviews to grasp an in-depth understand

Uppsatsen undersöker huruvida användningen av standardavtal vid offentlig upphandling av entreprenader inom Sverige innebär en inskränkning av den grundläggande unionsrättsliga friheten att tillhandahålla tjänster inom EU som säkerställs genom artikel 56 i Fördraget om Europeiska Unionens Funktionssätt. Entreprenadrätten är i Sverige oreglerad i lag och regleras istället genom standardavtal utformThis paper examines whether the use of standard agreements within public procurement of contractors in Sweden constitutes a restriction of the freedom to provide services within EU, which is ensured through article 56 in the Treaty on the Functioning of the European Union. Contract-law is not regulated through law within Sweden but is instead regulated through standard agreements developed by an i

Växthusgasutsläpp från mänsklig aktivitet påskyndar den globala uppvärmningen och måste åtgärdas. Informations- och kommunikationstekniksektorn (IKT-sektorn), som tillhandahåller det digitala samhällets tekniker såsom datorer, smarttelefoner och internet, står för en mängd växthusgasutsläpp som kan jämföras med flygindustrins. Aktörerna inom sektorn har ett ansvar att minska dessa och ett relativtThe ICT sector’s greenhouse gas emissions are comparable to those of the aviation industry, and the actors within the sector have a responsibility to reduce these in order to help combat global warming. A relatively new area of concern is the climate impact of software due to energy consumption. For example, AI has been acknowledged as an emissions-hungry technology because of the large computatio

Memory impairment and prominent hippocampal atrophy are the most recognisable features of Alzheimer’s disease (AD). It has been known that hippocampus and surrounding medial temporal lobe (MTL) structures support memory processes. However, specific function of each MTL subfield remains to be elucidated. Not all MTL subfields are uniformly affected by AD pathology and the spread of AD pathology fol

In Nampula Province, Mozambique, locating productive wells is a problem due to the heterogeneity in local geology, which consists of mainly weathered crystalline rock. This study estimates hydraulic conductivity of 10 hand pumped water wells in rural areas of Nampula Province using slug tests, and is a follow up of Andersson and Björnström (2013) and of Enkel and Sjöstrand (2013).

Popular Abstract in Swedish Inledning Kreativitet kan definieras på många olika sätt. I denna avhandling definieras kreativitet som ”ett generativt eller produktivt nytt sätt att uppleva verkligheten och sig själv på”, vilket är en något modifierad version av Smith och Carlssons (1990) kreativitetsdefinition. Det produktiva sättet att se på verkligheten uppkommer just av att man kan rekonstruera Four studies on creativity, imagination and self-image in 10-year-old children constitute the basis of this dissertation. A total of 179 participants were involved. Study I investigated two new creativity measurements comprising The Drawing Task, which had its starting-point in a brief story, and The Activity Questionnaire, which included questions about the children’s spare time activities. The h

The world faces major climate challenges and extensive efforts need to be taken to combat this issue. Replacing fossil-derived fuels and chemicals with renewables are one important step on the way. Hydrogen has a great potential as a renewable energy carrier for the transport sector and as a green chemical for the industry. Today, the production of hydrogen stems primarily from fossil resources. A

The concept “Broken Technologies” is related to the question: “Which is the benefit of humanity studies?” Of course the question is rhetorical because, how could this question be answered if the benefit was not obvious? Any answer supposes that we understand what we are asking for and the study of “what we mean” is one of the axes of the epistemology of the humanities. Anyway, we can also put the
