Abstract in Undetermined Packaging is of particular importance to retailers, since it can be considered an integral part of the product and the first point of contact with the brand (Rundh 2005). Over 73% of interviewed consumers rely on packaging to aid their purchasing decisions (Wells et al. 2007), and retailers are the ‘gatekeepers’ to the consumers (Dobson et al. 2003) via the retail stores,
Inom strålbehandling innebär den s.k. åskådareffekten ("bystander effect") ett relativt nytt tankesätt som betonar de biologiska effekterna av strålning på icke-bestrålade celler i närheten av bestrålade celler. Denna effekt har visat sig påverka inte bara de celler som angränsar till det bestrålade området utan även celler på större avstånd. I Lund pågår just nu ett projekt där man villPurpose Intensity modulation of radiation is one of several important conditions to evaluate for full understanding of how cells involved in the bystander effect influence each other when cells are exposed to radiation at low and high dose rates. The aim of this study was to develop and apply a useful and practical dosimetric method for measurement of the absorbed dose to cell cultures exposed to
Fotoner som penetrerar ett material har olika sannolikheter att växelverka och därmed överföra sin energi och absorberas i materialet eller få en riktningsförändring. Denna sannolikhet för fotonen att absorberas eller spridas anges ofta per längdenhet och kallas för attenuering. Sannolikheten för attenuering i ett material ökar med sjunkande fotonenergi och om materialet består av ett högre atomnuMaterial decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. The purpose of this thesis was to implement a material decomposition method, from the image acquisition
WHAT THIS STUDY ADDS Previous comparisons between open and endovascular repair of popliteal aneurysms have focused on asymptomatic patients, and have short follow up. This study is strengthened by the fact that it is contemporary, population based, without any selection bias, reporting on all kinds of presentations, and has approximately 90% 1 year follow up data. It shows that endovascular repair
Steriliseringslagstiftningens framväxt tog sin utgångspunkt i ”degenerationen” och oron för att industrialiseringen hade skapat en biologisk försämring av befolkningen. Det var vid denna tidpunkt som tankarna om rashygienen väcktes. Genom biologisk förädling skulle befolkningskvalitén höjas. Det fanns en förhoppning att genom positiv och negativ eugenik öka fortplantningen hos den ”goda” befolkninThe emergence of the sterilization law were based on "degeneration" and fear that the industrialization had created a biological degradation of the population. It was at this point that the ideas of the eugenics evoked. By biological processing the quality of the population should increase. There was a hope that through positive and negative eugenics increase the breeding of the "go
Background: Timely and safe elective health care facilitates return to normal activities for patients and prevents emergency admissions. Surgery is a cornerstone of elective care and relies on complex pathways. This study aimed to take a whole-system approach to evaluating access to and quality of elective health care globally, using inguinal hernia as a tracer condition. Methods: This was a prosp
I denna rapport redovisas populationstrender för 202 svenska fågelarter för åren 1975–2014. Fåglarna har räknats på vintern och på sommaren enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan 1996) men täcker hela Sverige. Nattaktiva fåglar har räknats sedan 2010. Även störrWe present the results of the Swedish Bird Survey, run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2014 include data from: 599 winter point count routes in 2013/2014 (39th winter), of which 294 were carried out during the Christmas/New Year count, 254 summer point count routes (40th ye
Acute lung injury (ALI) and its most severe form, acute respiratory distress syndrome (ARDS) limit the utilization of donor lungs for transplantation but is also a common cause of death in the intensive care unit. There is a general lack of diagnostic tools by which to assess lung function in ARDS but, in addition, the treatments offered are limited. In the present thesis, the aim was to explored
Pulchrol, a natural compound isolated from the roots of the vegetal specie Bourreria pulchra has been shown to possess potential antiparasitic activity toward Trypanosomatids, particularly against Trypanosoma cruzi, which causes the Chagas disease; and moderately against Leishmania species, responsible for Leishmaniasis. In this investigation, several pulchrol analogues were prepared and assayed t
Several plasticizing chemicals induce endocrine disrupting effects in humans, and the indoor environment is suggested to be a source of exposure. As children are particularly vulnerable to the effects from exposure to endocrine disrupting chemicals (EDCs), it is essential to monitor exposure to EDCs such as phthalates and non-phthalate plasticizers in indoor environments intended for use by childr
BACKGROUND: Epidemiologic studies have linked transportation noise to increased morbidity and mortality, particularly for cardiovascular outcomes. However, studies investigating metabolic outcomes such as diabetes are limited and have focused only on noise exposures estimated for the loudest residential façade.OBJECTIVES: We aimed to examine the influence of long-term residential exposure to trans
Background and Objectives Small vessel disease (SVD) and neuroinflammation both occur in Alzheimer disease (AD) and other neurodegenerative diseases. It is unclear whether these processes are related or independent mechanisms in AD, especially in the early stages of disease. We therefore investigated the association between white matter lesions (WML; the most common manifestation of SVD) and CSF b
Mineral evolution is concerned with the timing of mineral occurrences, such as the earliest reported occurrences in the geologic record. Minerals containing essential Li have not been reported from rocks older than ca. 3000 Ma, thus the lithian tourmaline (fluor-elbaite) and mica (lepidolite) assemblage from a pegmatite near Zishineni associated with the ca. 3000 Ma Sinceni Pluton presents unusual
BACKGROUND: We investigated the potential associations between cerebro-spinal fluid (CSF) levels of phosphorylated tau (P-tau) and total tau (T-tau) with short-term response to cholinesterase inhibitor (ChEI) treatment, longitudinal outcome and progression rates in Alzheimer's disease (AD). METHODS: This prospective, observational study included 129 participants clinically diagnosed with mild-to-m
BACKGROUND: Serbia, as the largest market of the Western Balkans, has entered socioeconomic transition with substantial delay compared to most of Eastern Europe. Its health system reform efforts were bold during the past 15 years, but their results were inconsistent in various areas. The two waves of global recession that hit Balkan economies ultimately reflected to the financial situation of heal
Ectomycorrhizae is a mutualistic association between roots of woody plants and a diverse range of soil fungi. The fungi exchange soil derived mineral nutrients for photosynthetic sugars from the host plant. The mycorrhizal symbioses are commonly found in all forest ecosystems and have a major ecological and economical importance. I have used comparative genomics, DNA microarrays and computational
Abstract: HLA‐DR2 is negatively associated with insulin‐dependent diabetes mellitus (IDDM). The aim of the present study was to analyze DR2‐positive patients among 425 consecutively diagnosed unrelated Swedish children with IDDM and in 367 matched controls. HLA‐DRB, ‐DQA and ‐DQB were determined by Taq I restriction fragment length polymorphism analysis. Amplification by polymerase chain reaction
Stationary solar energy concentrators are a promising option for decreasing the price of photovoltaic electricity. This thesis studies stationary concentrators in PV/Thermal applications. The studied systems are parabolic troughs intended for building integration. The first chapters briefly explain the optics of solar energy concentrators. The theoretical maximum concentration ratios of two and th
Background: The optimal surgical excision margins are uncertain for patients with thick (>2 mm) localised cutaneous melanomas. In our previous report of this multicentre, randomised controlled trial, with a median follow-up of 6·7 years, we showed that a narrow excision margin (2 cm vs 4 cm) did not affect melanoma-specific nor overall survival. Here, we present extended follow-up of this cohort.
