I takt med att världen blir mer medveten om hur människans beteende påverkar jordens klimat, ställs också högre miljömål. Ett hållbart energisystem är en del av dessa miljömål och att övergå till enbart förnybara energikällor är ett verktyg för att uppnå dessa. Övergången till endast förnybara energikällor riskerar dock att medföra problem, bland annat så kallad effektbrist. Effektbrist är inget nAs the world becomes more aware of how human behavior affects the earth’s climate, higher environmental goals are also set. A sustainable energy system is one part of these environmental goals, and switching to only renewable energy is a tool to reach such goals. However, a system with only renewable energy can be vulnerable at time periods of reduced production of electricity, with a subsequent r

Denna uppsats ämnar att kasta ljus över humanitära interventioner och huruvida de är lagliga enligt folkrätten idag samt om deras rättsliga ställning är på väg att förändras i framtiden. Fokus i uppsatsen ligger på den humanitära krisen i Syrien och hur de rättsliga övervägandena såg ut för en humanitär intervention där, samt vad som blev implikationerna för den gällande rätten efter denna kris. UThis essay seeks to shed some light on the concept of humanitarian intervention and whether it is considered legal or not in international law. Furthermore, the concept of humanitarian intervention is discussed in a developmental perspective, where the current regulation of humanitarian intervention is analysed and suggestions are presented for what might be the future for the concept. The essay f

Sedan miljöbalken trädde i kraft den 1 januari 1999 har ett antal rättsfall kommit vilka behandlar verksamhetsutövares ansvar för föroreningar som har skett före det datum då miljöskyddslagen trädde i kraft den 1 juli 1969. I 8§ i lagen om införande av miljöbalken är frågan om under vilka förutsättningar en verksamhetsutövare är ansvarig för gamla föroreningar tydlig; utövaren är ansvarig om den mThe Environmental Code (Miljöbalken) came into force 1 January 1999. Since then, there have been several legal cases that concern the operator’s liability for contaminated land. Some of these cases concern pollution that have occurred before 1 July 1969, when the Environmental Law (Miljöskyddslagen) came into force. The Environmental Code and the Promulgation Law sets out clear conditions of lia

Undersökning och hantering av arsenikförorenade brunnar i Nicaragua Arsenik förorenar dricksvatten i Nicaragua och framkallar cancer. Lösningen är enkel: sand, tegelstenar och järnspikar. Varje år dör hundratusentals människor till följd av arsenikförorenat dricksvatten. Världshälsoorganisationen WHO listar arsenik på topp-tio-listan över de kemikalier i världen som hotar människors hälsa mest. The awareness of problems concerning arsenic contaminated drinking water sources has during recent years increased. WHO (World Health Organization) decided in 1993 to lower the recommended limit of arsenic in drinking water from 50 μg/l to 10 μg/l, mainly due to observations of its carcinogenicity. New places where the WHO limit for arsenic is exceeded are constantly discovered all over the world.

Colombia committed to reduce 20% of its emissions by 2030 in the framework of Paris Agreement. The study provides a systemic approach that considers the two main drivers of the emissions in the country to know how realistic is the mentioned intended National Determined Contribution (iNDC). It analyzes deforestation and road transport with a methodology that combines analyses of their current situa

Öresundsregionen växer och i takt med en ökad befolkning och nyetablerade industrier blir behovet av el allt större. Samtidigt som elbehovet ökar är elnätet bristande och med en kärnkraft som håller på att avvecklas hotas områden i södra Sverige av elbrist. För att kunna möta de framtida utmaningar som samhället står inför har Malmö Stad inlett ett projektsamarbete vid namn M21 tillsammans med närThe Öresund region is expanding with a growing population and newly established industries which leads to an increased demand of electricity. At the same time as the demand of electricity is increasing there is are deficiencies in the power grid and a dismantling of nuclear power which creates a situation where parts of southern Sweden are threatened by power shortage. In order to prepare for futu

Vid avdelningen för kärnfysik utvecklas för närvarande andra generationens Ir-koincidensspektrometer. Anledningen till detta är att det finns ett stort behov bland geologer att mäta spårkvantiteter av Iridium i olika geologiska skikt för att korrelera skiktens ålder med eventuella stora meteoritnedslag. Första generationens spektrometer byggde på en dubbelkoincidens mätt med två HPGe-detektorer, mPresently, the development of the second generation Ir coincidence spectrometer is talking place at the division of Nuclear Physics. There is a large need among geologists to measure trace quantities of Ir in different geological layers and correlate the age of the layer with different large meteorite impacts. The first generation Ir spectrometer was based on a coincidence measured by two HPGe det

More and more corporations around the world is starting to work in project form and leaving their traditional function based way of organising themselves behind. This leads to new ways of driving and implementing changes and improvements. It requires another approach and this approach has to deal with the individual employee in a greater extend. Alfa Laval often questions how to make a project to

Order Picking in warehouses is often optimized using a method known as Order Batching, which means that one vehicle can be assigned to pick a batch of several orders at a time. There exists a rich body of research on Order Batching Problem (OBP) optimization, but one area which demands more attention is computational efficiency, especially for optimization scenarios where warehouses have unconvent

We assess the sustainability of rural electrification in Manica Province, Mozambique, focusing on different alternatives for mini-grid and off-grid power supply. The qualitative assessment considers four dimensions of sustainability, namely environmental, socio-cultural, economic, and institutional. We argue that small-scale hydropower is the most sustainable alternative for off-grid or mini-grid

Conventional atomistic computer simulations, involving perhaps up to 106 atoms, can achieve length-scales on the order of a few 10s of nm. Yet many heterogeneous systems, such as colloids, nano-structured materials, or biological systems, can involve correlations over distances up 100s of nm, perhaps even 1 μm in some instances. For such systems it is necessary to invoke coarse-graining, where sin

The development of surfactant-templated mesoporous films grown at the air/water interface was investigated using specular and off-specular X-ray reflectivity techniques. The samples were prepared in acidic conditions using cetyltrimethylammonium bromide (CTABr, 0.075 M) and different concentrations (0.27-0.88 M) of tetramethyloxysilane (TMOS). At CTABr/TMOS molar ratio between 0.277 and 0.093, the

III-V co-integration is less mature compared to Si/Ge CMOS due to their inferior pMOS device performance. This letter adopts a novel quaternary InGaAsSb channel material in a core-shell vertical nanowire structure to overcome the limitations. A gate-last process achieves self-alignment of the drain and gate contacts. The improved electrostatics with short gate length ${L}_{\text {g}}$ = 60 nm resu

Finding the correct top dead center (TDC) offset for an internal combustion engine is harder than it seems. This paper introduces a novel method to find the TDC offset based on a simple assumption that the heat loss power through the combustion chamber walls is constant for motored cycles in a narrow crank angle interval around TDC. The proposed method uses nonlinear least squares optimization to

Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. Thus characteristics of particle emissions from biofuel combustion may be important in the assessment of health effects
