Trots att bemanningsbranschens utveckling på arbetsmarknaden har ökat de senaste åren har forskningen och kunskapen om bemanningsanställda inte ökat i samma takt. Den psykosociala arbetsmiljön har förändrats de senaste decennierna i och med framväxten av alternativa anställningar. Både den fysiska och psykosociala arbetsmiljön har betonats som viktig för personers hälsa och välbefinnande. I arbetsThe development of temporary agencys on the labormarket has been increasing over the past years, despite of this the research and knowledge about temporary workers has not increased in the same pace. The psychosocial environment has changed the past decades with the emergence of alternative empolyments. The importance of the physical and the psychosocial work environment has been emphasized for th

Cofactors are essential for the growth of bacterial pathogens also inside a human host and one source of cofactors are proteins in blood. Pathogens can use surface proteins to bind and extract cofactors from these blood proteins. Here, using protein modeling of these proteins in complex with bacterial protein combined with bacterial growth assays with blood proteins from different species, we demo

The automotive industry, a matured and vital global sector, is currently facing the biggest upheaval so far in the necessity to emancipate itself from fossil fuels. This moment before technical revolution is used for a detailed comparison of innovative performance of the sector in the last 15 years. With innovation being interpreted along the lines of technical progress in key variables, this thes

En optimal tolerans är nyckeln till att skapa en produkt som är både billig att tillverka och samtidigt uppfyller kraven gällande livslängd och funktion. Att hitta den optimala toleransen är ofta betydligt svårare än vad man tror och kräver både tillverknings- och konstruktionskunskap.In recent years measurement techniques and equipment have developed well. The new measurement technology has made companies realize that products not are according to drawings. Meanwhile the products still works as planed and can be sold to customers. The reason that the details are not according to drawings can be traced to a surface with narrow angle tolerance. The project is limited to two sma

What factors should be taken into account in the transfer of knowledge in the construction industry? The report aims to identify the knowledge transfer process in the construction industry between actors in the production. This is done to improve the operators' understanding of the importance of knowledge and see what factors can help to improve the results of the execution.

The physicochemical properties of oat β-glucan have been shown to govern its health benefits by a plethora of studies. However, the effect of the passage through the gastrointestinal tract on the conformational and structural characteristics is not fully explained. The aim of the present study was to elucidate the effect of in vitro gastrointestinal conditions on the structure and conformation of

The research is done in order to analyse management of waste beverage containers in Belarus and the effectiveness of policies implemented to address it. The analysis is followed by exploring whether the introduction of deposit-refund system (DRS) would help to address packaging waste issue in Belarus and, if so, what features the DRS should possess to be effective in current context. The study des

Based on the context of a developing country, this research engages key identified political-economy aspects that influence the operations and performance of the electricity supply industry in Tanzania. Departing from this political-economy perspective, this paper explores dencentralized approaches to rural electrification through agro-industry co-generation and influencing factors behind the slow

Growing amounts of waste generation in remote areas without proper waste management systems is a problem to human health and the environment. The Amazon holds the biggest freshwater resources in the world, is a biodiversity hotspot and its communities are placed in distances that can take days by boat to be reached. A National policy with EPR instruments requires private companies to take-back pac

Världens sötvattensystemen är sårbara och har upplevt betydande miljöförändringar. Utöver direkt mänsklig påverkan, innebär klimatförändringar ytterligare påfrestningar på våra färskvattenresurser. I denna studie undersöks hur klimatförändringar har påverkat tidsperioden av istäckning i svenska sjöar och vattendrag. Observationer från över 750 sjöar och vattendrag i Sverige har analyserats, med viThe worlds freshwater systems are vulnerable and have experienced significant environmental changes. In addition to direct anthropogenic impacts, climate change poses yet another source of pressure on the freshwater resources. This study investigates climate change impacts on ice cover duration in Swedish lakes and rivers. In situ observations from over 750 lakes and rivers in Sweden were analyzed

Inom hjärnforskning önskar man ta reda på värdet för olika kemiska parametrar. Här beskrivs en metod som med ren matematik kan beräkna de optimala parametervärdena. Den bakomliggande kemin gav upphov till speciella matematiska egenskaper. Med hjälp av en egenutvecklad sats kunde det då visas att metoden alltid hittar den lösning som är bäst enligt den så kallade maxnormen.In this thesis, functions describing relations between chemical concentrations at equilibrium are studied. The functions have some parameters that are desired to be determined. Based on the properties of the functions, an optimization method will be proposed. Because of these special properties, it is appropriate to consider the residuals in the max norm, since then it is possible to show that the

This master thesis is written at the faculty of engineering at Lund University in collaboration with IKEA Industry. The aim is to analyze the potential in electricity production from excess wood biomass coming from production. The available biomass varies in form, quantity, size and moisture content. Various technologies, handling different kind of feedstock for electricity production were investi

Conditional Cash Transfer (CCT) programs aim to alleviate short term poverty and reduce intergenerational poverty by supplying targeted poor households with cash transfers contingent upon certain program parameters, such as school attendance for children. Evaluation on CCTs have found that such programs generally increase school enrolment and school attendance but its subsequent effect on labor ma

Nowadays, the use of digital signal processing is essential in various measurements of different machines. There has been many projects done at Sandvik AB on how to collect and measure data signals on the cone rock crusher. None of those measurements could present the correct data. The reason could possibly be due to the lack of theory behind the use of digital signal processing which this thesis

It is commonly understood that Intellectual Property Regimes are aimed at protecting private rights and in doing so sometimes neglect public interests. Historically IP systems were considered to allow authors or creators to secure certain monopolies on rights, hence in the 1970s and 1980s the concern over public needs came forward requiring the IP system to respond to it in a way that would stimul

Examensarbetet är utfört på och i samarbete med Imtech Ventilation i Malmö. Författarens avsikt har från början varit att skapa något som kan vara till stor nytta för företaget. Därför har examensarbetet utförts i nära samarbete med Imtech Ventilations medarbetare. Författaren har gjort en bakgrundsanalys av energikravs-läget i byggbranchen.

Bus lanes are being built as a measure to increase the share of public transport, thereby reducing congestion and environmental impacts. Evaluations are rarely made and the effects of the measures are therefore, in many cases unknown. It is currently unclear whether there are some general correlations between the Swedish cities where bus lanes have been built. This report examines the general tren
