Do sick birds migrate at different times than healthy ones? The word migration comes from the Latin migratus that means “to change”, referring to how birds change their geographic locations seasonally. Birds migrate to escape from decreased food availability or harsh weather on their breeding grounds. They migrate to areas of high or increasing resources where they stay during the winter period b
Populärvetenskaplig sammanfattning: Är klimatforskningen skev? En central fråga är om vi kan lita på att vetenskapliga tidskrifter återger en rättvis bild av aktuella forskningsresultat? Dessutom bör vi fråga oss hur rapporteringen påverkas då betydande händelser sker inom vetenskapsvärlden. I november 2007 och senare 2009 skedde två viktiga företeelser inom klimatforskningen som potentiellt kanAbstract The declaration of a scientific consensus concerning anthropogenic causes for climate change by the IPCC in their fourth assessment report (AR4), published in 2007, initiated a heated debate. During this debate, experts within the IPCC were accused of selective reporting and the AR4 got strong source criticism by politicians, stakeholders and climate skeptics in general. The debate furth
Popular science summary: The Battle Against Cancer Daily, people are diagnosed with cancer, a disease that brings suffering and despair. I'm sure you have heard about chemotherapy and radiation as a way of trying to treat cancer, but it is equally important to find an effective method to quickly and reliably detect a tumor at an early stage, before it is too late. In my master's thesis,
This study was performed using daily spot prices, from January 1997 through July 2004; of the three assets that constitute the crack spread i.e. crude oil, gasoline and heating oil - all listed on the New York Mercantile Exchange (NYMEX). Our objective has been to characterize the dynamics of the spread and subsequently create trading strategies to yield returns that surpass that of a passive appr
Background: Fibroblast growth factor 23 (FGF23) is the earliest marker of disturbed mineral metabolism as renal function decreases. Its serum levels are associated with mortality in dialysis patients, persons with chronic kidney disease (CKD) and prevalent cardiovascular disease (CVD), and it is associated with atherosclerosis, endothelial dysfunction and left ventricular hypertrophy in the genera
Background: Metabolic syndrome (MetS) remains a controversial entity. Specific clusters of MetS components - rather than MetS per se - are associated with accelerated arterial ageing and with cardiovascular (CV) events. To investigate whether the distribution of clusters of MetS components differed cross-culturally, we studied 34,821 subjects from 12 cohorts from 10 European countries and one coho
Background: Frontotemporal dementia (FTD) is recognised as a clinically and morphologically heterogeneous group of interrelated neurodegenerative conditions. One of the subtypes within this disease spectrum is the behavioural variant FTD (bvFTD). This is known to be a varied disorder with a mixture of tau-positive and tau-negative underlying pathologies. The other subtypes include semantic dementi
Objective To investigate the possible association of the BANK1 gene with genetic susceptibility to systemic sclerosis (SSc) and its subphenotypes. Methods A large multicentre case-control association study including 2380 patients with SSc and 3270 healthy controls from six independent case-control sets of Caucasian ancestry ( American, Spanish, Dutch, German, Swedish and Italian) was conducted. Th
Background: Currently available biomarkers for the early tissue process leading to joint damage in rheumatoid arthritis are insufficient and lack prognostic accuracy, possibly a result of variable activity of the disease over time. This study represents a novel approach to detect an altered activity of the disease process detected as increasing serum-COMP levels over a short time and whether this
In this thesis a comparative study of Sweden and Thailand was conducted in order to find out why Sweden is top-ranked and Thailand low-ranked on an e-learning readiness scale. More specifically, I was focusing on the net universities in Sweden and in Thailand. The net universities and the countries were contrasted in order to find out, not only if the differences or similarities had any influence
Nanotechnology is a collective definition referring to every technology and science which operates on a nanoscale. Nanoparticles have different properties than larger particles and these properties can be utilized in a wide spectre of areas such as in medicine, information technologies, energy production and storage, materials, manufacturing and environmental applications. Although nano-derived a
In the 1960:s the Swedish government approved a decision that led to the construction of about one million households during the years 1965-1975. Today these buildings are both deprived and suffer from high energy consumption. To address these problems individually is very expensive. If it instead is done simultaneously substantial savings can be made. The company AB Helsingborgshem owns and manag
During the past two decades several studies pointed out the contradiction between abundance of natural resources and its negative impact on economic growth and development. This paradox has been widely observed and documented throughout the development literature. In this context, China’s increasing demand for natural resources and consequent growing trade and influence in developing countries has
Crowdsourcing is a relatively new technique which aims to make a specific group of people contribute solutions to simple tasks or problems that are published online by some organization. For this they get some reward, which is usually economic in nature. This technique can be embraced by any kind of company, and since it is done online, it can turn out to be a bit problematic, especially when it c
Syftet med denna kandidatuppsats är att belysa hur man inom svensk rätt sett på problematiken rörande simulation av sinnessjukdom, när simulantens intention varit att undvika straff. Jag har använt mig av ett rättshistoriskt perspektiv och berör inte modernare lagstiftning än den som är stiftad tidi-gare än år 1929. Även om huvudsyftet är simulationsproblematiken har jag ansett det viktigt att ge The purpose of this bachelor’s essay is to show how the Swedish legal sys-tem has dealt with simulation of mental illness, where the simulator’s pur-pose was to avoid conviction. I have used a legal historical perspective and the essay does not concern more modern legislation than that made before the year of 1929. Though the main subject of the study is simulation, I have also described the rest
This study aims to evaluate the potential of a reuse system for furniture, focusing on students in Lund, this study. The study suggests that furniture has a high potential for increased reuse, partly because of its intrinsic, durable characteristics, and partly because of the students’ positive attitude towards second-hand furniture. The study also suggests that necessary features for such a syste
lnvestigation of weak gravel for road construction has been going on at VTI for many years. The overall aim has been to find test methods that correspond with what happens in the road and that are easy to use in any road laboratory. Following methods have been used in this investigation: planetarytype mixer for wear tests, freeze-thaw variation for weathering tests, Californian Bearing Ratio (CBR)
