En ökad medvetenhet om värdet av ett rent grundvatten yttrar sig i allt fler sammanhang, bl.a. i det nationella miljömål om grundvatten av god kvalitet som riksdagen presenterat. Simrishamns kommun ser över vattenskyddsområdena runt kommunens grundvattentäkter för att säkerställa ett rent grundvatten. Målet med detta examensarbete är att ta fram ett underlag som skall kunna ligga till grund för avThe increased awareness of the value of clean groundwater can be seen in a growing number of contexts. This is also emphasized in the national environmental goals, put up by the Swedish government. The municipality of Simrishamn, in southern Sweden, is re-evaluating the extension of the existing restriction areas around the groundwater wells of the municipality. The aims in this investigation were

Populärvetenskaplig sammanfattning: I en mosse i södra Sverige, som heter Viss mosse, har fynd av trädstammar gjorts. Fynden gäller ek, bok och al. Denna horisont med trädstammar tyder på att miljön på mossen var förhållandevis torr när träden levde, eftersom det normalt sett är för blött på en mosse för att ekar och bokar ska kunna växa där. Kol-14-dateringar visar att träden dog för cirka 3 200 Findings of a tree stump horizon in Viss mosse, a raised bog in Scania, southern Sweden, indicate relatively dry conditions on the bog during the lifetime of the trees . 14C-datings show that the trees died about 3 200 years ago. Four peat cores were collected from the bog in order to investigate whether climatically induced water level fluctuations were responsible for establishemt and death of t

Aim The aim of the thesis is to explore the meaning of the brand within the Knowledge Intensive Business Service (KIBS) sector, through the brand’s construction and management, in order to contribute with insights into the interaction between branding theories and the sector. Theoretical perspective Theories collected and reviewed are focused on three main fields (I) characteristics of the K

In this paper we will investigate whether the ethnic composition of a county affects their trust. More specifically we will answer the question: does the ethnic composition affect the level of trust in Sweden and are there any specific factors that increase this effect? In order to do this we use data on Swedish citizens from the year 2001 to the year 2012. As an approximation for ethnicity we use

Tidsbegränsad anställning i Sverige har ökat kraftigt de senaste årtiondena och lagstiftningen har gått från att bara tillåta tidsbegränsad anställning om arbetsuppgifternas särskilda beskaffenhet föranledde det, till att idag inte ställa några särskilda krav alls. Lagstiftningen försöker balansera motstående behov, anställningstrygghet kontra flexibilitet. På grund av reglernas semidispositivitetFixed-term employment in Sweden has increased significantly over the recent decades. The legislation tries to balance conflicting needs between employment protection and flexibility and has developed from only allowing fixed-term employment when warranted by the specific nature of the work to not state any specific reasons at all. Through a collective agreement it is also possible for the social p

Dagens krav på läkemedel är höga, de ska t.ex. stanna kvar i kroppen under lång tid, ha lång hållbarhetstid och vara lätt att dosera. Att PEGylera ett läkemedel kan ge dessa egenskaper. Idag är dock denna tillverkningsprocess långsam och ger ett lågt utbyte. Size Exclusion Reaction Chromatography (SERC) är en ny teknik som förhoppningsvis ska förbättra denna process. Protein är idag vanligt förekoThe PEGylation process is a covalent attachment between a protein (the pharmaceutical) and poly ethylene glycol (PEG) and since the beginning in 1977 PEGylation processes have been used to improve pharmaceuticals. PEGylation of a pharmaceutical achieves improved properties like greater solubility in water, longer residence time in vivo and extended shelf life. The PEGylation process is in general

För att begränsa den globala uppvärmningen krävs en omställning mot en klimatmässigt hållbar livsmedelsförsörjning. Konsumtionen av kött och mejeriprodukter, som idag står för en stor andel av matens klimatpåverkan, behöver minska till förmån för mer resurseffektiva vegetabiliska livsmedel. För att kunna komplettera eller ersätta animaliska näringskällor berikas många växtbaserade produkter med inIn order to mitigate the global warming, a transition towards a sustainable diet is required. Such a transition includes reduced consumption of meat and dairy products, by substituting these with more resource efficient vegetable-based products. In order to meet the nutrient content of animal foods, vegan products are often supplemented with artificial vitamins and minerals. Few studies have inves

Bakgrund: Till följd av att den globala konkurrensen tilltar, ökar komplexiteten, flexibiliteten och produktvariationen inom produktion. Detta leder till att förbättringsprojekt blir allt svårare att genomföra. Händelsestyrd simulering har i litteraturen blivit identifierat som ett verktyg med förmågan att lösa dessa utmaningar, men till följd av att komplexiteten i en produktion ökar, växer ocksåBackground: Following a growing global competition, complexity, flexibility and product variability of manufacturing systems are increasing. This has led to improvement projects becoming more difficult to carry out. Discrete event simulation (DES) has in literature been identified as having the capability to solve these challenges, but as complexity of a manufacturing system increases so does also

Over the past decade, flooding has been a great issue for several countries in Europe. With the movement of people and assets to flood prone areas, consequences due to flooding are increasing. Coping with this problem requires an effective response to flood risks. Therefore, this work has aimed to describe the emergency response to the 2013 flood incident in Suffolk, UK. This, in order to provide

The aim of this study was to describe how families with children, having cognitive disabilities, interacted with portable electronic assistive devices in their daily life. More specifically, its aim was to study the needs for families when they decided to use electronic assistive devices as assistance in their everyday lives, what everyday function they added value to and if they had the same mean

I Sverige finns 51 samebyar, dessa är uppdelade mellan tre typer av samebyar: skogssamebyar, fjällsamebyar och koncessionssamebyar. Samebyarna är både ekonomiska och administrativa sammanslutningar men även ett geografiskt område, inom vilket samebyns rennäring bedrivs. Skogssamebyars och fjällsamebyars medlemmar har bara jakträtt på sina byområden som är belägna på lappmark och renbetesfjället. KIn Sweden there are 51 sámi villages (samebyar), which are divided into three different forms: skogssamebyar, fjällsamebyar and koncessionssamebyar. These sámi villages are both administrative and economic associations and geographical areas where the sámi village’s reindeer husbandry is pursued. The members of skogssamebyar and fjällsamebyar only have the right to hunt in their village area if th

Offentlig upphandling handlar om hur den offentliga sektorn ska agera vid inköp och har därmed en betydande påverkan på samhällsekonomin. Essentiella samhällsfunktioner som exempelvis sjukvård och skolor tillgodoses genom offentlig upphandling. Eftersom inköpen görs via skattemedel har samhällsmedborgare ett intresse av att förfarandet går rätt till. Vidare har leverantörer ett intresse av att förPublic procurement concerns how the public sector should act when making purchases and therefore has a great impact on the national economy. Fundamental societal functions such as healthcare and education are supported through public procurement. Because these purchases are made using tax revenue, citizens have an interest in ensuring that the procedure is conducted properly. Moreover, suppliers h
