Hippocampal focal T2 hyperintensities (HT2Hs), also referred to as hippocampal sulcal cavities, are a common finding on Magnetic Resonance (MR) images. There is uncertainty about their etiology and clinical significance. In this study we aimed to describe these HT2Hs in more detail using high resolution 7 Tesla MR imaging, addressing 1) the MR signal characteristics of HT2Hs, 2) their occurrence f
Background: Diabetes mellitus (DM) is known to negatively affect quality of life (QoL), yet very few studies have been done on QoL of patients with diabetes in the United Arab Emirates population. Objectives: The aim of this study was to assess the impact of DM on health-related QoL (HRQoL) of patients with diabetes of Emirati nationality. Methods: Two hundred and forty Emirati patients with diabe
The first part of this study focuses on the effect of cone calorimeter test variables on polyurethane flexible foam properties such as ignitability, heat release rate, effective heat of combustion and mass loss. Three of the main commercial foam types were used, i.e. conventional slabstock foams, high‐resilience slabstock foams and all‐MDI (methylene diphenyldiisocyanate) moulded foams. A decrease

Three of the main commercial foam types were used; viz. conventional slabstock foams, high resilience slabstock foams and all-MDI moulded foams. A decrease in heat flux (down to 40%) with
An apparent wave is a part of the sea record observed between two successive upcrossings of the still water level integral formulas are given for intensities of encountered waves that overtake a ship sailing in directional sea with constant velocity. The formulas can be evaluated exactly in the case when the directional spectrum is known and the sea is assumed to be Gaussian, i.e. is a sum of noni
Popular Abstract in Swedish Att klara sig trots allt: Den sociala och produktiva dynamiken hos småbönderna i de halvtorra områdena i Iringa i norra Tanzania. Det är inte lätt att överleva som småbonde i de halvtorra områdena i Iringa och på liknande platser i Afrika. Man kontrollerar knappast sin egen livssituation. Regnen är opålitliga, priser, marknadsföring och politiska ingrepp är oförutsägbaWhile much of semi-arid Africa is still sparsely populated with unused land, there are everywhere pockets of high and increasing population density in attractive locations. Small-scale farmers can respond to beginning land-scarcity in a number of ways. Through migration, through diversification of livelihoods, or through changes in their farming system. Which solution is chosen, depends not only o
Popular Abstract in Swedish Tillväxthormon (GH) insöndras stötvis från hypofysen. Insöndringen är som högst nattetid, och de högsta nivåerna ses under puberteten för att därefter avta succecivt med ökande ålder. En av de vanligaste orsakerna till brist på GH är godartade tumörer i hypofys och hypofysnära områden där även behandling med kirurgi och strålbehandling kan bidra till hypofysinsufficiensIn childhood onset growth hormone deficiency (GHD) a reduction in cardiac left ventricular mass (LVMi) and impairment of cardiac systolic function, as well as in glomerular filtration rate (GFR) has been shown. In study I, we showed that a low dose of GH treatment for 10 months resulted in increased LVMi and kidney size. No significant improvement in cardiac systolic function or GFR, except for a
Popular Abstract in Swedish Tillgången till rent vatten är avgörande för människans överlevnad, tillgång till vatten kan förbättra den allmänna hälsan och därmed också vår fortsatta existens på jorden. Naturkatastrofer eller mänsklig påverkan genom t.ex. industrin kan dock resultera i att vattenkällor, tidvis eller permanent, blir förorenade med miljögifter som hindrar människans konsumtion av renThe lack of safe, clean water is strongly linked to poverty, underdevelopment and poor health. Water is needed not only to sustain life, but to produce food and in industrial processes. Anthropogenic pollution and natural events can jeopardize access to safe water. Inorganic pollutants or toxic metal ions such as arsenic and cadmium are of special concern since these are persistent and accumulate
In “Weighing Lives” (2004) John Broome criticizes a view common to many population axiologists. This is the view that population increases with extra people leading decent lives are axiologically neutral: they make the world neither better nor worse, ceteris paribus. Broome argues that this intuition, however, attractive, cannot be sustained, for several independent reasons. I respond to his criti
The day Faraday moved a magnet in and out of a wire loop and detected the time-varying magnetic field, the first wireless transmitter / receiver system was created and the world was changed forever. However, it took almost fifty years for Heinrich Hertz to use Maxwell's equations and Faraday's insights in his professorship at Karlsruhe to create the first electromagnetic wireless communication sys
Varje år tvångsomhändertas tusentals barn av socialnämnden och placeras för vård enligt LVU i ett familjehem. Att tvångsvårda ett barn är mycket ingripande, men vad innebär egentligen ett sådant omhändertagande? Vad kan barnets familj göra och vad har socialnämnden för skyldigheter för att möjliggöra ett upphörande av vården? Ställs barnkonventionen mot EKMR i någon del av processen och vad innebäEach year, the social service forcibly places thousands of children for care within LVU in a foster home. To forcibly place a child for care is a very intrusive measure, but what does this placement really mean? What can the child’s family do and what obligations do the social service have for the care to cease? Is the convention on the rights of the child put against ECHR at any moment and what d
Can normal development help us understand tumor initiation? The field of developmental biology studies the complex processes by which organisms grow. Embryology is one of its subfields and investigates how organisms develop from the moment the egg is fertilized to the later embryonic stages. Embryonic development can sometimes be abnormal and lead to cancer formation. In higher animals, followi
The energy issue has in recent years become a hot topic around the world. Discussions about how to reduce the greenhouse gases in a sustainable manner have been raised. Given that this is an emerging problem, and that many people lack knowledge regarding this subject, it is about time that they get the information needed to be able to contribute in some way. In general, the building sector represe
Forecasts and analysis on real estate values and house prices are an ever-present problem for several different players. Often there is debate about the values of housing prices or housing bubbles in the Swedish cities. The difficulty with the valuation of housing, compared with other products, is their unique location. No housing is another comparable, and because of this there is no certain mark
Arid and semiarid Middle Eastern countries generally, and Syria in particular, face serious water shortage problems and challenges with water sustainability. Climate change, population growth, and economic development play a major role in decreasing available water resources per capita. This, in turn, has great impact on domestic, agricultural, and industrial water use. In this study, marginal and
The Internet has revolutionised the global market place. Internet shopping is now accessible to an increasing numbers of people. In theory, this new form of media offers convenience, speed and choice to the consumer, but the question is whether it works in practice? Business-to-consumer cross-border transactions, whether carried out electronically or otherwise, are subject to the existing framewor
This degree project focused on the evaluation of the facilities, production process and conditions within a brewery production site in order to identify potential contamination risks in the beer production process and suggested actions for improving and enhancing protection against contamination. The project was performed in collaboration with a microbrewing company that produces beers with differ
Unlocking the hidden connection: How asthma gets into your head Have you ever wondered if asthma, a common lung condition, could have effects beyond just your breathing? Recent scientific studies are revealing a fascinating connection between asthma and the brain, bringing to light an unexpected link that has puzzled researchers for years. Asthma is an allergic disease characterized by lung inf
