Utvecklingen av samhällsfastigheter har under de senaste åren gått från att vara en kommunal angelägenhet till något som allt fler aktörer fått upp ögonen för. Ett stort behov av skolplatser och särskilda boenden för äldre har inneburit att flera svenska kommuner avyttrat sin mark till både privata och kommunala bolag som får stå för utvecklingen av morgondagens skolor och äldreboenden.

The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. Human activities' continuous greenhouse gas emission has contributed to global climate change, which has caused some atmos
Suddträsket är ett internationellt erkänt våtmarksområde av stor betydelse som ligger beläget längst Vita Nilen i Sydsudan. Våtmarkens unika ekologiska miljöer har lett till skapandet av flera naturskyddsområden för bevarandet av de naturliga habitaten och dess ovärderliga ekosystemtjänster. Tillsyn av skyddsområdena bidrar i allmänhet till deras bevarande. Däremot har de pågående politiska osäkerThe Sudd wetland, situated along the White Nile in the Republic of South Sudan, is recognized internationally for its unique environmental features. The distinctive ecological characteristics have resulted in the creation of numerous nature reserves in efforts to conserve the habitats and ecosystem services provided. Monitoring changes within the nature reserves usually contributes to their protec
Lipids in the presence of a solvent can through the process of self-assembly form a number of phases referred to as Lipid Liquid Crystalline (LLC) phases. The inverse hexagonal, inverse bicontinuous cubic phases and sponge phase are examples of LLC structures that have been studied and used in drug delivery settings or food applications. For this project the focal point will be the sponge (L3) pha
Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions. This implant fixation is highly dependent on
The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. Firstly, a custom-made flavor was created for the experiments covering as much as possible a broad area of compounds prec
Tunnel structures play an important role in Sweden’s infrastructure. At shallow depths, a common construction method is the so-called “Cut-and-Cover” tunnel, where the tunnel placement is excavated, cast in concrete on-site, and then backfilled. Such tunnels are typically subjected to constant water pressure, which yields high demands on crack control. Cracking in elongated concrete structures oft

The proposals are analysed against children’s rights under the Convention o
Background: There is increasing recognition of stroke as an important contributor to childhood morbidity and mortality. Current estimates of global childhood stroke burden and its temporal trends are sparse. Accurate and up-to-date estimates of childhood stroke burden are important for planning research and the resulting evidence-based strategies for stroke prevention and management. Objectives: T
AbstractThe overall aims of this thesis were to use echocardiography to non-invasively, delineate early structural andfunctional changes following orthotopic heart transplantation (OHT), and to define reference values in the contextof gender and bridging with mechanical circulatory support.Several factors might affect myocardial function in OHT patients rendering the use of normal values fortranst
BACKGROUND: Breast cancer in young adults has been implicated with a worse outcome. Analyses of genomic traits associated with age have been heterogenous, likely because of an incomplete accounting for underlying molecular subtypes. We aimed to resolve whether triple-negative breast cancer (TNBC) in younger versus older patients represent similar or different molecular diseases in the context of g
Introduction Episodic memory allows us to revisit our past and recollect inter-related elements that characterize life events (Tulving, 1983). When forming such relational memories, we only apprehend a small part of our visual field in full acuity at a time. This limitation is overcome by shifting visual attention over a sequence of eye movements. We bind these visual “samples” of the world into
Increasing CO₂ emission is considered as the main reason for global warming in the world. One of the reasons for producing CO₂ is using of fossil-based materials in the construction projects. This study intends to assess the using bio-based materials instead of fossil-based materials for the thermal insulation layer of the external walls and roofs. Another focus of this project is using green conc
Radiation protection is of importance for the general public, patients and personnel in many different situations: rare accidents involving ionizing radiation, medical examinations or work tasks in the medical clinic or nuclear industry to name a few. Optimization in radiation protection and limitation of radiation doses are essential to prevent overexposure and for reducing negative health conseq
Dialectical Behavior Therapy (DBT) has been developed in the USA by Marsha M Linehan, during the last two decades. Linehan elaborated this method for self-destructive women and in continuous cooperation with those women in treatment throughout her research. Randomised controlled studies have showed good results for self-destructive women with a borderline personality disorder. This group of patien
Uppsatsens övergripande syfte är att utifrån 2014 år sexualbrottskommitténs förslag utreda eventuella konsekvenser av en samtyckesreglering i våldtäktslagstiftningen, ur ett bevisrättsligt perspektiv. En våldtäkt kan se ut på flera sätt, den gemensamma nämnaren är att handlingen anses utgöra en gränslös kränkning av den sexuella integriteten och självbestämmanderätten. Dagens lagstiftning har fåThe main purpose of this essay is to examine, from the Sexual Offences Commissions proposal, the possible consequences of a regulation based on consent and how it will affect assessment of evidence. A rape can occur in a variety of ways, what they have in common is to be considered a boundless violation of a person’s sexual integrity and self-determination. Today’s legislation has received strong
Arbetstagarskyddet vid verksamhetsöverlåtelser regleras inom Europeiska unionen (EU) av Rådets direktiv 2001/23/EG av den 12 mars 2001 om till-närmning av medlemsstaternas lagstiftning om skydd för arbetstagares rättig-heter vid överlåtelse av företag, verksamheter eller delar av företag eller verk-samheter (överlåtelsedirektivet). I svensk rätt har reglerna implementerats ge-nom ändringar i lag (The protection of employees in the case of business transfers is regulated within the European Union (EU) by Council Directive 2001/23/EC of 12 March 2001 on the approximation of the laws of the Member States relating to the safeguarding of employees’ rights in the event of the transfer of under-takings, businesses or parts of undertakings or businesses (Transfer of Un-dertakings directive).

The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. In the conversion between blue light and light of lower energy approximately 25-45 % of the radiant power is lost
Det är inte ovanligt att upphandlande myndigheter använder sig av referenser i upphandlingsprocessen. Ett exempel är att den upphandlande myndigheten ställer krav på att anbudsgivarna ska presentera referenser, exempelvis om hur en tjänst likartad den som offereras i upphandlingen tidigare har utförts eller referenser som styrker krav på en viss kompetens. Det är då fråga om referenser i form av kIt is not uncommon for contracting authorities make use of references in the procurement process. One example is that the contracting authority requires that bidders must present credentials, such as how a service similar to that quoted in the contract has been experienced or references proving the requirement for a specific skill. This is then a question of credentials in the form of qualificatio
