Polyethylene terephthalate (PET) beverage bottles that were refillable or that contained recycled material, either in direct contact or with a functional barrier protecting the food, were investigated with focus on odorous compounds f

Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

The development of the European Higher Education Area (EHEA) is firmly rooted in the idea of higher education (HE) as the cornerstone of a knowledge-based society. Throughout Europe, HE bodies are addressing issues of quality, mobility, employability and lifelong learning. HE agencies and institutions alike are working hard to harmonise European degrees and apply quality assurance standards (ESG,

The management of primary gastrointestinal stromal tumours (GISTs) has evolved with the introduction of adjuvant therapy. Recently reported results of the SSG XVIII/AIO trial by the Scandinavian Sarcoma Group (SSG) and the German Working Group on Medical Oncology (AIO) represent a significant change in the evidence for adjuvant therapy duration. The objectives of this European Expert Panel meeting

Objective: To review the literature regarding indications, surgical details, postoperative care, complications, functional outcomes, as well as quality-of-life measures of patients with different forms of ur

ABSTRACT: BACKGROUND: The study was designed to investigate the effect of different measuring methodologies on the estimation of P wave duration. The recording length required to ensure reproducibility in unfiltered, signal-averaged P wave analysis was also investigated. An algorithm for automated classification was designed and its reproducibility of manual P wave morphology classification invest

Popular Abstract in SwedishVad är åldrande? När började man över huvud taget tala om ”åldrande”? När fick ordet ”pensionär” den betydelse vi är vana vid idag? I Åldrandet och språket studeras ord och uttryck för att ringa in vad man har menat med hög ålder och åldrande i Sverige under hundraårsperioden mellan 1875 och 1975. Frågor kring hög ålder och åldrande har stor aktualitet idag. I Sverige ocThis thesis analyses how old age and ageing were manifested and understood in Sweden from approximately 1875 to 1975. It thus aims to provide historical background to current debate about for instance the retirement age and how to best care for the elderly. Encyclopaedia entries from both the beginning and the end of this period describe ageing as a medical process of physical decline. Since much

Popular Abstract in Swedish Proteiner är biologiska molekyler som kan utvinnas ur olika bakterier, svampar, djur och människor. I sin naturliga miljö bidrar de bl. a. till att katalysera (snabba på) olika kemiska reaktioner (enzymer), att sköta transporten av olika molekyler, bidra till immunförsvaret och tillväxtkontroll (hormoner). Upptäckten att proteiners olika funktion kan uttnyttjas i många The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. NMR spectroscopy revealed changes in the relaxation properties of Ala and Thr methyl groups in lysozyme, indicating compression of the enzyme as a consequence of pr

The over-riding aim of this thesis was to obtain a deeper understanding of the way patients with cardiac problems view both information related to their health and medical decisions and their role in decision-making processes. An important objective was to identify reasons why patients do not ask for or assimilate information or why they do not want or feel that they are able to influence medical

I Regeringsformen som är Sveriges grundlag står det uttryckligen att Sverige är en suverän stat med ett demokratiskt statsskick. Men efter Sveriges inträde i Europeiska Unionen 1995 har lagstiftningen av bl.a. direkta skatter kommit att påverkas avsevärt, trots att Sverige inte har överlåtit dessa till EU-institutionerna. EU-domstolen har i brist på harmonisering på eget initiativ utformat prejudiThe Constitution Act, which is Sweden's constitution explicitly, states that Sweden is a sovereign state with a democratic form of government. But after Sweden joined the European Union in 1995, legislation of particular direct taxes come to be affected significantly, although Sweden has not transferred them to European institutions. EU court for lack of harmonization of its own initiatives de

Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in

Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to

När trapetskorrugerad plåt installeras som tak, skruvas den fast på överflänsen på den fackverksbalk som utgör takets bärverk. Takplåten har hög styvhet i planet, men dess styvhet minskar när deformation uppstår i taket, på grund av andra ordningens effekter. För att avgöra hur stor påverkan som detta har på en strukturs stabilitet, modelleras en byggnad i ett kraftfullt datorprogram där linjära oCorrugated galvanized iron (CGI), or corrugated sheet metal, is a lightweight roofing material that was invented in the early 1800s. The corrugation gives the steel an increased flexural strength in its installed direction and thus increases the amount of load the CGI-plate is able to carry and the span it can be effective at. Thanks to its light weight, corrugated sheet is one of the most commonl

Vid en diskussion om nivån på den svenska bolagsskatten är det av stor vikt att avgöra huruvida diskussionen rör den nominella eller den effektiva skattesatsen. Den nominella skattesatsen uppgår till 28 procent och återfinns i 65 kap. 14 § IL. Den effektiva skattesatsen är däremot inte given utan kan i viss utsträckning påverkas, eftersom den bestäms genom att dividera skatt på årets resultat med

The topic of this thesis deals with the implementation deficit in the environmental sector that exists within the EU. According to the 25th annual, report from the Commission, there were over 3400 complaints and infringement files under 2007. The environmental sector was the area with the highest number of open cases that concerned non-compliance in 2006 Sweden is however one of the best Member St

Den internationella syndikerade lånemarknaden har sina rötter från 1960-talet och har alltsedan dess varit en av de största, mest flexibla och viktigaste finansieringskällorna för stater och företag världen över. Från 1990-talet fram till och med finanskrisens utbrott hösten 2008 växte marknadsvolymerna kraftigt. Sedan dess har volymerna minskat dramatiskt. Kärnan i ett syndikerat lån är att tvåThe international syndicated loan market has its roots from the 1960s and has ever since been one of the largest, most flexible and most important sources of funding for states and corporations worldwide. From the 1990s until the financial crisis started in the autumn of 2008 market volumes grew sharply. Since then, however, volumes have dropped dramatically. The core of a syndicated loan is that

The human race has for a long time contributed to an increase of the environmental problems, however in recent times they have begun to deploy measures to counter this. One of these measures is environmental classification systems, which is used in the construction- and property sector. Environmental classification systems are methods which evaluate a building's environmental performance in or
