Popular Abstract in Swedish Naturliga störningsregimer är viktiga drivkrafter i vegetationsdynamiken hos de flesta skogstyper jorden runt. Att förstå de rumsliga och tidsmässiga egenskaperna i störningarna, såväl i nutid som i förfluten tid, är viktigt bl a vid utformningen av strategier för naturvård, likväl som för att kunna modellera inflytandet av klimat och människans påverkan. I denna avhandNatural disturbance is an important driving force of community dynamics in many forest types around the globe. Understanding spatial and temporal properties of disturbance events in the present and in the past is important in formulating the nature conservation strategies as well as for the modeling of climate and human impacts on forest vegetation. In this thesis I studied wind and fire disturban

NMR relaxation experiments have provided a wealth of information about molecular motions in macromolecules and ordered fluids. Even though a rigorous theory of spin relaxation is available, the complexity of the investigated systems often makes the interpretation of limited datasets challenging and ambiguous. To allow physically meaningful information to be extracted from the data without commitme

Popular Abstract in Swedish Sammanfattning Teknik är alltid skapad för en förväntad brukare i ett antaget sammanhang. Inom kommersiell luftfart är dessa antaganden när det gäller design tydliga. Såväl besättning som utrustning är certifierad för en viss typ av operationer i enlighet med flygplanets drifthandbok. Trots denna genomtänkta definition av användare i sitt sammanhang händer det ändå attAbstract Technology is always designed for an assumed user in an assumed context. In commercial aviation, these design assumptions are clearly spelt out in that both crew and equipment are certificated for a specific operation as stated in the aircraft flight manual. Despite this well defined user context, the designed-for and the real contexts often differ enough so that adaptations of working p

Popular Abstract in Swedish Recenta dödismiljöer framför Brúarjökull-glaciären på Island och Holmströmbreen på Svalbard har undersökts med speciellt fokus på landforms- och sedimentgenes samt kvantifiering av dödisavsmältningen. Fältmätningar, studier av tidsserier av flyg? och satellitbilder samt digitala terrängmodeller är dataunderlaget för kvantifieringen av dödisavsmältningen. SedimentologiskModern dead-ice environments in the glacier forefields of Brúarjökull, Iceland and Holmströmbreen, Svalbard were investigated with focus on landform and sediment genesis, as well as quantification of melting. Field monitoring and studies of multi-temporal aerial photographs, satellite imagery, and Digital Elevation Models (DEMs) provided data for the melting quantification. Sedimentological and ge

The DO3SE (Deposition of O-3 for Stomatal Exchange) model is an established tool for estimating ozone (O-3) deposition, stomatal flux and impacts to a variety of vegetation types across Europe. It has been embedded within the EMEP (European Monitoring and Evaluation Programme) photochemical model to provide a policy tool capable of relating the flux-based risk of vegetation damage to O-3 precursor

Since 1992 semi-continuous in-situ observations of greenhouse gas concentrations have been performed at the tall tower of Cabauw (4.927 degrees E, 51.971 degrees N, -0.7 ma.s.l.). Through 1992 up to now, the measurement system has been gradually extended and improved in precision, starting with CO2 and CH4 concentrations from 200 ma.g.l. in 1992 to vertical gradients at 4 levels of the gases CO2,

Popular Abstract in Swedish Denna skrift behandlar marklagring av värme, kyla och kärnavfall.The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. All these storage systems induce multidimensional, time-variable thermo-hydr

BACKGROUND & AIMS: Little is known about recurrence of pancreatitis after an initial episode, and little is known about how the disease progresses or what factors affect progression. We performed a population-based study of patients with acute pancreatitis (AP) to determine their outcomes and associated factors. METHODS: We performed a retrospective study of patients with first-time AP from 20

SAMMANFATTNING Syftet med denna uppsats har varit att utreda frågan huruvida FN:s konvention om avskaffande av all slags diskriminering av kvinnor (kvinnokonventionen) bör göras till svensk lag för att öka jämställdheten mellan män och kvinnor. I detta syfte diskuterar uppsatsen kvinnokonventionens jämställdhetsstandard och konventionens ställning i Sverige. Vidare presenteras och analyseras för- SUMMARY This study aims to examine whether the UN Convention on the Elimination of Discrimination Against Women (CEDAW) should be incorporated into Swedish law, in order to enhance equality between women and men. This study discusses the anti-discrimination standard of CEDAW and the status of the convention in Sweden. Furthermore, this study presents and analyses the pros and cons of the incorpora

Kvinnojourerna uppkom för att stötta kvinnor som utsattes för våld i nära relation. Aktivister ansåg inte att myndigheter kunde tillgodose det behovet och därför startades det på deras eget bevåg ideella organisationer som drevs av ideellt aktiva kvinnor för att hjälpa och stötta dessa kvinnor. En förändring i en samhällelig diskurs bidrog till en förskjutning av våld i nära relation från att ha vThe emergence of women’s crisis centres in Sweden occurred when women activists recognised the need to offer shelter and support to women who were being subjected to intimate partner violence. The activists realised the authorities were unequipped and unwilling to offer support to victims of abuse and therefore started independently a movement of volunteer organisations who aimed to enact the supp

Background The 2002 EU directive on the energy performance of buildings stipulates that buildings must be energy certified. In order to implement the directive in Sweden it is proposed that a law on the energy certification of buildings be introduced on 1 January 2006. The law shall apply to all buildings where energy is used to condition the indoor climate. However, there are a number of exceptio

Background: Mental illness is a significant public health issue among young adults in Sweden, who are also spending less time in nature despite its proven positive health effects. However, there is limited research on young adults’ relationship with forest visits from a mental health perspective. Aim and Research questions: This study aimed to explore young adults' experiences and perceptions

The European spruce bark beetle is a major disturbance agent in Norway spruce forests in Europe, and with a changing climate it is predicted that damage will increase. To prevent the bark beetle population buildup, and to limit further spread during outbreaks, it is crucial to detect attacked trees early. In this study, we utilize Sentinel-2 data in combination with a risk map, created from geodat

[Background] The previous studies suggest that radioactive elements like Cs+and Sr may adversely affect marine ecosystems and the fishing industry. Traditional treatment systems for radioactive wastewater like the Advanced Liquid Processing System (ALPS) and Kurion have faced challenges in limiting concentration and achieving safety criteria. Studies suggest potential long-term impacts on benthic

BackgroundThe epidemiological association between type 2 diabetes and cataract has been well established. However, it remains unclear whether the two diseases share a genetic basis, and if so, whether this reflects a putative causal relationship.MethodsWe used East Asian population-based genome-wide association studies (GWAS) summary statistics of type 2 diabetes (Ncase = 36 614, Ncontrol = 155 15

Seagrass meadows constitute important habitat for a plethora of organisms, rendering them important habitats for conserving biodiversity. Seagrass meadows also modify the environment by attenuating wave and current energy. As a result of this, seagrass meadows trap organic matter and in addition to their high productivity, are able to sequester carbon that is stored in their underlying sediments.

Ultrarelativistic heavy-ion collisions, which take place at particle accelerators like the BNL Relativistic Heavy Ion Collider (RHIC) and the CERN Large Hadron Collider (LHC), are known to produce a strongly-interacting, fluid-like state of matter referred to as the Quark-Gluon Plasma (QGP). Despite the medium’s short lifetime of approximately 10-23 s, its presence is known to influence particle p

Characterizing the onset and progression of Alzheimer’s disease pathologies relative to one another is important for biological staging and clinical trial design. Recent advances in blood plasma assays of Alzheimer’s disease amyloid and tau pathology have enabled detection of Alzheimer’s disease pathophysiology during life, but it remains unclear when plasma biomarker abnormalities are detectable

Introduction: Most centers treating patients with anorectal malformation (ARM) will screen for anomalies of the kidneys and urinary tract by using ultrasonography. There is no consensus on whether screening for vesico-ureteral reflux (VUR) should occur. To meet the diagnostic needs of ARM patients a method was developed to include a simultaneous VUR diagnosis and pre-reconstructive fistula work-up

Context. Next to H and He, carbon is, together with oxygen, the most abundant element in the Universe and widely used when modelling the formation and evolution of galaxies and their stellar populations. For the Milky Way bulge, there are currently essentially no measurements of carbon in un-evolved stars, hampering our abilities to properly compare Galactic chemical evolution models to observatio
