Public procurement and the purchasing of goods, services and works comprises about 14% of the European gross domestic product (GDP). Procurement initiatives, guidance and tools therefore can have significant influence to leverage demands for more sustainable and circular products and services. This study explores the current circular public procurement (CPP) landscape, looking at barriers and oppo

Bin i södra Indien Vilda bin är mycket viktiga för både vilda blommor och grödor, eftersom de hjälper till att pollinera dem så att de kan bilda frön och sätta frukt. Över hela världen har dock antalet vilda bin minskat vilket kan innebära problem för både ekosystem och jordbruket. En stor orsaken till minskningarna är att jordbrukslandskap har intensifierats, vilket har gjort att landskapet har 1. Wild bees are very important for pollination of both wild flowers and agricultural crops, benefitting seed set and yields. However, declines in bee populations have been observed across the world and it has been proposed that the intensification of agriculture including landscape simplification by loss of natural habitats, is a major reason for these declines. India is undergoing large-scale ag

Seafood can be a potential source of contaminants and when consumed contribute to an increased exposure of these substances. Per- and poly-fluoroalkyl substances (PFASs) are contaminants accumulating in our seafood and are therefore an emerging concern. It has been suggested that cooking seafood can influence the concentration of heavy metals and other organic contaminants, however, few studies ha

The unicellular Gonyostomum semen (class Raphidophyceae) is an invasive microalga which can dominate phytoplankton communities during blooms, with economic and ecological consequences. Its abundance in European freshwaters has been mainly explained by water temperature, colour, and acidity. While low pH and brown colour are common features of lakes containing the species, it has also been found in

7 miljoner människor dör varje år på grund av cigarrettrökning. Idag finns det flera olika produkter på marknaden som kan hjälpa personer att sluta denna dåliga vana. Den första var Nicorette® tuggummin. När McNeil AB producerar Nicorette® tuggummin, följer McNeil de strikta kraven på kvalité som de regulatoriska myndigheterna kräver. Dessa krav tvingar McNeil att slänga tonvis av tuggummin varje McNeil AB produces pharmaceutical chewing gums that contains nicotine. Since this smoking cessation product is a pharmaceutical, the regulatory agencies demand that any gums outside pre-set specifications are discarded. Some batches have more discarded material than others, due to the variability in the manufacturing process. By analysing this variability, the personnel could make choices that low

The aim of this thesis is to investigate if the Lutheran heritage, represented by a comparison between early Lutheran writings and Luther’s source of inspiration Theologia Germanica, can provide a starting point for potentially unifying dialogues within Christian circles. The background of this pursuit of unity is the ecumenical problem of the seemingly opposite views of how faith and deeds relate

Waste management is one of the key environmental issues identified in Sri Lanka. Waste generation is linked with the increase of population and urbanization. Polyethylene and other plastics have become a significant consumable material in lifestyles of the public as well as all types of industries in the country. The plastic consumption is high with the sophistication of living standards of the li

Since the introduction of Edison’s lightbulb over one-hundred years ago, humanity has struggled to keep up with electrification for all. With global attention now aimed at sustainable energy production, the struggle becomes more complex by not only obliging energy access, but access to clean energy. The concept of microgrids has been promising for filling in the demand, but not quickly enough to m

The world's fisheries have been in decline for more than forty years. In Mexico, about 80% of the fishery resources are at maximum capacity levels or overexploited. Given the magnitude of the problem, there is a need for solutions that involve all actors in the fish supply chain. However, solutions and research on how actors in the middle of the supply chain such as restaurants can be integrat

Electronic products consist of substances that can be harmful to human health and the environment if exposed or leaked during the product use and end-of-life phases. Full Material Disclosure (FMD), which usually requires suppliers to disclose on the concentrations or masses of all substances in a product, is one method of increasing supply chain transparency on chemicals in products. This case stu

At the 3 MeV light ion accelerator of the Lund Ion Beam Analysis Facility (LIBAF), a beamline is about to be constructed with the purpose of producing neutrons as a higher yield complement to the current Source-Testing Facility. When operational, the beamline will provide the possibility of tagging both thermal and fast neutrons. These neutrons will be used to test and characterise new available m

Den första delen är en källtextanalys där textens kontext och viktigaste drag presenteras enligt Hellspong & Ledins (1997) analysmodell. Därefter följer överväganden inför översättningen med en kort diskussion

The paper focuses on three key factors in WTI crude oil futures market: Convenience yield, inventory level and price volatility. The main purpose of the paper is to investigate the relation between those three key factors and analyze how those key factors will affect the market trading behaviors. Market trading behaviors could be measured from various aspects though, our paper will use open intere

Musical meaning is multifaceted: both highly sensory and yet often abstract, able to cross cultural boundaries and yet embedded in specific traditions. For the most part it is not denotational (Monelle, 1991). Nevertheless, in “programmatic music”, musical themes are intended to refer to worldly objects and events on the basis of iconic (and indexical) grounds. Such non-arbitrariness of the sound-

Genom att se på data från 195 tillfrågade studenter undersöker denna uppsats betalningsviljan för subscription video on demand (SVOD). Fokus har framför allt legat på att studera hur betalningsviljan ändras då SVOD-produkten differentieras (vertikalt) genom två kvalitetsaspekter; färskhet och kvantitet. Den första aspekten undersöker effekten av när innehållet på SVOD-tjänsten hade premiär på biog

The fashion industry is currently operating at high levels of material throughput leading to global annual emissions reaching a staggering 4 metric gigatons of CO2e. Almost reaching the levels of the entire EU-28 in 2015 of 4.45 metric gigatons. As consumption levels could increase by as much as 63% by 2030 there is urgency to address the situation. The application of Circular Economy (CE) princip

This thesis concerns the relationship between grammar education and writing. This is approached in two ways, which are expressed in the two research questions. They are as follows: Does grammar education improve students texts and does grammar education affect students writing processes. The method used to investigate the research questions, is an elicitation task which has generated texts from un

Kan den genetiska koden leda till nedsatt hälsa? Genetisk forskning har gett en otrolig mängd information om vår hälsa och förmåga att bekämpa infektioner. Ny forskning har fokuserat mycket på huruvida en aktiv gen påverkar sjukdomar. En aktiv gen producerar proteiner, som i sin tur bidrar till kroppens funktioner. Det finns många gener som inte är aktiva eftersom deras proteiner inte har en bidr

Sedan 1970-talet har antalet rapporterade cancerfall dubblerats, dels på grund av förändrade levnadsvanor och dels på grund av bättre screeningmetoder som upptäcker cancern i tidigt skede. Tidig upptäckt av cancern i kombination med utvecklad cancerbehandling har bidragit till att risken för att avlida av cancer har minskat. Cancerbehandling sker huvudsakligen genom operation, strålbehandling elleAim: The tomotherapy system offers two radiation techniques, TomoHelical (TH) and TomoDirect (TD). The aim of this master thesis was to evaluate TD as a treatment alternative mainly by comparing TD treatment plans with 3DCRT plans and comparing TD plans with TH plans, separately, in the thoracic and abdominal regions. An additional aim was to examine if the current patient specific quality control

Hjärntumörer utgör cirka 2,5% av alla cancerdiagnoser i Sverige (2013) och femårsöverlevnaden är cirka 50%. Hjärntumörer diagnostiseras med bildtagningstekniker såsom datortomografi (CT), positronemissionstomografi (PET) och magnetkamera (MR). En MR-bild byggs upp av signaler från protoner i vatten, som är en av människokroppens vanligaste beståndsdelar. För att möjliggöra diagnostisering och klasBackground and Purpose: Dynamic glucose-enhanced (DGE) imaging is a novel technique that can be used to assess information about microvasculature by using natural sugar (D-glucose) as a biodegradable contrast agent. The method relies on chemical exchange saturation transfer (CEST). The hydroxyl protons in glucose are saturated using a selective radio-frequent pulse and will subsequently exchange w
