Den offentliga upphandlingen utgör en avsevärd del av samhällsekonomin. Den upphandlingspliktiga volymen motsvarade 15,5 - 18,5 procent som andel av Sveriges BNP 2012. Lagen om offentlig upphandling tillåter olika angreppssätt för att utvärdera anbud. Syftet med uppsatsen är att undersöka vilken av de två vanligaste utvärderingsmetoderna mellan relativa metoden och den absoluta metoden som ger de

Byggarbetare är mer utsatta för fallolyckor än arbetare i andra branscher. Idag fallolyckor är den vanligaste och det är även de vanligare dödsorsakerna i byggindustrin. Under de senaste åren visat sig att fallolyckor ligger högst bland de andra orsakerna till anmälningar om olycksfall med sjukfrånvaro. Den senaste statistiken om fall olyckor ligger ungefär 44 % av de andra arbetsolyckorna. Under

Populärvetenskaplig sammanfattning Mask eller fisk? Silltrutars (Larus fuscus) födosök på jordbruksmark under häckningsperioden på Gotland, Sverige Den Baltiska underarten av silltrut (Larus fuscus fuscus) förekommer inom ett relativt litet område i Europa. Silltruten är "nära hotad" i Sverige men orsakerna till dess nedgång är okända. Största häckningskolonin i Sverige, på Stora KarlAbstract The Baltic sub-species of the lesser black-backed gull (Larus fuscus fuscus) occurs within a relatively small region in the Palearctic. It is a monomorphic marine predator that winters in the Mediterranean and Africa. It is listed as ‘near threatened’ in Sweden and the reasons for its decline are not known. The largest breeding colony in Sweden, located on the island of Stora Karlsö, Got

Hellre fly än illa fäkta ”Hemma är där man sist satte sig” som vårtsvinet Pumbaa i filmen Lejonkungen så vackert myntade. Men många är nog de, vilka associerar ordet flytta med ett lägenhetsbyte från en stadsdel till en annan, från större till mindre, från mindre till större. Att flytta är dock inte något som är unikt för människan, långt ifrån. Inom biologin används termen migration, ett fenomeAbstract In nature, a majority of migratory populations are composed of a mixture of both seasonal migrants and year-round residents, a phenomenon known as partial migration. It is of great importance to identify the factors causing the variation in individual decisions of whether or not to migrate. Partly for a more profound understanding of the evolution behind animal migration, and moreover th

This paper will have a focus on hip hop and feminist theory. The theory is based on Judith Butler's theory of gender as discursive and performative and heterosexuality as the norm. The norm of heterosexuality is influenced by the power structure presented by Michael Foucault and his theory of sexuality and power. The material that will be investigated consists of rap lyrics from 10 Swedish hip

Linking partial migration to the breeding grounds Partial migration is a behaviour that characterise a single population within which only some individuals migrate. That gives a unique chance for comparison of individuals that leave the breeding grounds during winter and the other individuals that remain the whole year round. This may cause several differences between the individuals that belong

This bachelor’s thesis is a study about guidelines on gender equality and gender mainstreaming. The theories used are queerfeminism, performativity and normcritical perspective. The purpose with the study is to understand how two organisations work with gender equality and gender mainstreaming in relation to their guidelines. The research questions were: (1) Is it possible to understand gender mai

Crude oil is the most traded energy commodity in the world, and its price has a large impact on the everyday life of billions. Given the volatility of crude oil prices and its enormous effects on economies worldwide, there has been a growing demand for risk quantification and risk management for the market participants. The measurement known as Value-at-Risk (VaR) has become the industry standard

The purpose of this research is to conduct a critical study which focuses on getting deeper insights into in-application advertising, especially, to understand the details of making in-application advertising, and to develop the existing advertising model for applying to the in-application advertising specifically.

"There is a crack in everything. That's how light gets in." With two simple sentences the famous poet Leonard Cohen describes his perception on how light interacts with matter. This thesis work will try to give a more precise and detailed description of the interaction between light and nano-materials that maybe is going to lose some of the magic that poetry has but this will be com

All industrial facilities and large warehouses require some sort of lighting solution. They have ongoing activities with workers and trucks moving around at various speed, and to avoid accidents these lighting solutions are often very bright and energy consuming. The most common solution is fluorescent light. These lights are energy consuming and not dimmable. Turning these off by night or when th

Salinomycin attackerar cancerstamceller i hypoxi Bröstcancer är den näst vanligaste typen av cancer i Sverige och representerar cirka 15 % av alla cancerfall, med mer än 7500 nya fall årligen. Ett stort problem, som forskningen och sjukvården kämpar med, är tumörer som sprids och som återkommer efter några år. Den orsakande faktorn bakom dessa problem tros vara en liten mängd resistenta cancerce

Abstract European blackberries constitute a polyploid complex of closely related microspecies, which includes species in Rubus sect. Rubus and Rubus sect. Corylifolii of Rubus subgenus Rubus. These species reproduce by facultative agamospermy. New microspecies evolve from time to time by hybridization between Rubus sect. Rubus and R. caesius or R. idaeus, or by sexual reproduction. Because of the

Effekter på mossammansättning vid avverkningar i tallskog i södra Sverige Andelen skyddad skog är idag låg och för att ta reda på hur arter och mångfald kan bevaras måste produktionsskog studeras. Bottenskiktet i form av t.ex. mossor har stor betydelse för förekomst av andra artgrupper och även kommersiellt vid skogsföryngring. Sedan tidigare finns studier på långtidseffekter av kalavverkning meIn this study bryophyte species richness, abundance and sexual reproduction was screened in sampling plots in a planted costal Scots pine forest set in a logging system in Southern Sweden, with control plots in the adjacent nature reserve. Data was collected from seven different stands, with equal stand structures in a chronosequence after commercial thinning; data was in the same way collected fr

The information contained in the DNA (Deoxyribonucleic acid) of an organism that will finally be expressed, is first converted into a molecule called RNA (Ribonucleic acid). This is mainly composed of two types of sequences: the exons, carrying the information that will give rise to the formation of proteins and will be finally expressed in the organism, and the introns, which mainly include regul

Behandling av lakvatten inom avfallsdeponierna Syftet med projektet var att utvärdera den faktiska lakvattenreningskapaciteten inom Hedeskogas avfallsanläggning, Skånes län. Målet var även att mäta eventuell bakterieaktivitet i dess dammar, i vilka lakvattnet hanteras. Men vad är då lakvatten? Lakvatten produceras varje gång vatten infiltreras genom ämnen samt när olika sorters substanser samlas Dissolved ammonia is often referred to as one of the major contaminants in landfill leachates. Discharge concentration limits for municipal wastewater treatment plants in Sweden have been tightened in order to meet higher water quality standards. Because of REVAQ, a certification system tailored to ensure better sludge quality, wastewater treatment plants may decide whether to accept leachate from

Food trucks provide personalized experiences by eliminating anonymity and allowing the customer to slow down and engage. Their mobility facilitates transformation and a sense of occasion, thus possessing elements of performance, urgency and excitement. Having the ability to define spaces and revive locations, food trucks creates affiliative communities with natural meeting locations. The food truc

In several years after its discovery in the placenta, the human leukocyte antigen (HLA) class lb protein, HLA-G, was not given much attention, nor was it assigned great importance. As time has unraveled, HLA-G has proven to have distinctive functions and an unfore­ seen and possibly important role in reproduction. HLA-G is characterized mainly by its low polymorphism and restricted tissue distribu

MicroRNAs (miRNAs) are an exciting new field which has been connected to different cancers and cellular imbalances. In previous studies, our group has been able to find a correlation between miR-96 and prostate cancer (PC). Here we studied miR-96’s effect on the cell-cell adhesion protein E-cadherin’s RNA and protein expression levels upon miR-96 inhibition. Furthermore, because the bone is one of
