Miljörelaterade, sociala och ekonomiska effekter av en ökad plaståtervinning i Sverige Dagens plastproduktion är förknippad med åtskilliga miljöproblem. En av de största utmaningarna är att en betydande del av den plast vi konsumerar hamnar i världshaven. År 2050 förväntas plastproduktionen vara fyra gånger större än vad den är idag. Om vi inte agerar kommer det snart finnas mer plast (i vikt) änThe rapidly growing, global plastic production and the waste generated as an effect of this is associated with countless environmental problems. As this sector continues to expand, so will the problems. Further complicating is the fact that currently only a small proportion of plastic is being recycled or re-used. A majority of the recyclable plastic in the EU and in Sweden is instead being incine

Historically, there has been a gap between business users and IT, and that gap is present in the BI context as well. As an attempt to bridge the gap, SSBI offers an environment which challenges the roles of business users and IT. Business users are empowered technically to create their own reports, while the role of IT shifts from being a roadblock to becoming a collaborator in meeting business ne

A high informality incidence, measured as the share of informal employment out of total employment, is a common characteristic of most developing countries’ economies. In Mexico, where informal employment accounts for the majority of labour activity, this is argued to be a consequence of its unique social policy. The introduction of the social protection program for health in 2002, Seguro Popular,

Women make up most of the high-skilled workers in OECD countries, a trend that has been on the rise since the 80’s. The main hypothesis of this paper is that women migrate more than men due to the cultural impositions of gender roles on their freedom. This paper benefits from using the most comprehensive dataset on brain-drain available, that contains data for 193 countries throughout 30 years, an

Located in Båstad, at the Bjäre peninsula, is the camping business Båstad Camping. With many guests from all over of Sweden, the owners of the business want to convey information about tourist attractions, sporting activites, events and restaurants at the Bjäre peninsula in a modern way. The purpose of the thesis is to develop a visitors mobile application with information about the Bjäre peninsul

Bostik AB has long had a production where parts of the production are done manually. These parts include that an employee needs to lift a rubber pulp from a conveyor belt, twist and put the rubber pulp into a pallet. The employee should then put on a plastic patch between each layer. This process can in the long run be unhealthy for the employees who will carry out the movement because repeated li

Reduced growth rates in saturated developed economies have put increasing pressure on multinational companies (MNCs) to expand to rapidly developing emerging markets and capitalize on their value potential. Yet, this value potential comes with several challenges which are very different from what firms experience in developed countries, especially with regards to the bottom of the pyramid. The Tra

Sedan decennier har digitaliseringen pågått i så gott som alla arbetsorganisationer. Just nu pågår andra generationens digitalisering med artificiell intelligens, robotar och andra typer av ”smarta lösningar”. HR-anställda befinner sig på flera sätt mitt i händelseutvecklingen. De utgör en allt mer strategisk partner, förväntas kunna kommunicera digitalt på interna nätverk och kunna översätta data

The understanding of development and disaster nexus has enforced the international community to think and act differently. Disaster risk reduction mainstreaming has been embraced as one of our best approach for sustainable development and has been consistently featured in international discussions. Mainstreaming in general is known to be a complex process requiring a set of institutional arrangeme

I detta examensarbete granskades värmeöverföringen mellan två zoner i en bubblande fluidiserad bädd och det resulterande temperaturfältet med numeriska strömningsberäkningar av en laminär Euler-Euler-tvåfluidbeskrivning. Syftet var att uppskatta den termiska potentialen att flerstega en kraftvärmepanna genom integrering av en kommunicerande förgasningsreaktor som utnyttjar värme från förbränningenIn this Master's thesis, the heat transfer between two zones in a bubbling fluidized bed and the resultant temperature field were examined using a laminar Eulerian-Eulerian two-fluid model in computational fluid dynamics. The purpose was to estimate the thermal potential to multi-stage a combined heat and power boiler by integration therein of a communicating gasification reactor, which utiliz

Många av oss äter dagligen läkemedel i tablettform, men vad innehåller egentligen en tablett, förutom den aktiva ingrediensen? Och hur vet man om de andra ingredienserna passar ihop när man gör tabletten? I ett projekt under våren har olika polymerer testats för filmdragering av en tablett som löser upp sig i munnen.Polymeric film coating is widely used in the pharmaceutical industry as a way of improving the features of a dosage form. Common polymers used for pharmaceutical coating are hydroxypropyl methylcellulose (HPMC) and polyvinyl alcohol (PVA). Coatings can have various benefits, one being protection of the active pharmaceutical ingredient (API). For a dosage form to be stable, it is necessary that e

On one hand Self-help is seen as social instrument providing disabled people assistance and emphasizing the citizen's motivation and commitment in compensating for their needs. But historically, on the other hand, Self-help in terms of care in a social repayment- and control system is interpreted from an intellectual clash between philanthropic and liberal thinking about the right to care, res

Bakgrund: Enligt lag har föräldrar rätt till information om spädbarnsuppfödning som är korrekt och objektiv för att utifrån det kunna göra ett informerat val gällande metod för uppfödning. Informationen skall således behandla både amning och uppfödning med ersättning alternativt båda delar. Syfte: Att belysa förstagångsföräldrars erfarenheter av valet av uppfödningsmetod. Metod: En kvalitativ semi

Chromosome defects in high hyperdiploid childhood acute lymphoblastic leukemia Acute lymphoblastic leukemia (ALL) is a type of blood cancer that affects both adults and children. While human cells normally harbor 46 chromosomes, the leukemic cells of the high hyperdiploid subgroup (HeH) of childhood ALL presents 51-67 chromosomes, where the extra chromosomes are generally X, 4, 6, 10, 14, 17, 18

Långsamma pulser är intressanta för acceleration av till exempel protoner. Protoner som accelereras till höga hastigheter kan i förlängningen användas till mer skonsam behandling av cancer, där en större del av energin dödar cancercellerna istället för friska celler runt om. Det är emellertid mycket svårt att få protoner att färdas i de hastigheter som krävs. Konventionella partikelacceleratorer äPeriodic electron and ion density modulations in near critical density plasmas induced by counterpropagating femtosecond pulses of intensities on the order of 10¹⁵ to 10¹⁶ Wcm⁻² are described in a linear and stationary regime and investigated using particle-in-cell simulations in one and two dimensions. The periodic gratings produce transient plasma photonic crystals lasting up to several picoseco

Little is known about the spatial ecology of the Sunda clouded leopard (Neofelis diardi). Being rare and elusive rainforest dwellers, studying them is difficult. Basic knowledge on their home ranges and social organization is lacking, yet is crucial for maintaining viable populations in protected areas, in the scope of this Vulnerable species’ conservation. This study uses 10 years’ worth of came

Syfte: Syftet med den här studien var att undersöka om det förekom frågor

Air pollution has become a major worldwide concern due to the high levels of air pollutants emitted from industrial and traffic related activities. Exposure to air pollution has been linked to various negative health effects, ranging from asthma to chronic illnesses. Consequently, analyzing air pollution data has become an essential tool for giving insight about the potential health effects. Spati

Multi-scale modelling is a novel approach to fire modelling in situations where the size of the domain prevents it from being modelled completely in 3D. By splitting the domain in a 1D and 3D portion multi-scale modelling allows for much faster simulations which still adhere to the correct boundary conditions. In this thesis the multi-scale methodology is applied to the LHC accelerator in use at C
