Popular Abstract in Chinese 北极和亚北极地区对全球气候变化影响尤为重要。目前，北极地区正面临着变暖速度高于全球平均的现状。全球大约有50%的土壤碳储存在高纬度地区的土壤里，这些土壤碳主要分布于冻土层和泥炭层中。冻土层的解冻会使原先被冻结的土壤碳加速分解，产生温室气体，从而对全球变暖形成一个强烈的正反馈。与此同时，气温的增加可能会很大程度地影响植被在这些地区的生长和分布。动态生态系统模型是一种非常强大的工具，被用来研究气候变化对生态系统的影响，并且可以量化生态系统对大气的反馈信息。然而这些模型通常只关注大气、地表植被和土壤之间的水和碳的纵向转移，从而忽略了其在模型空间单元中的横向移动。这样可能会导致模型对于水和碳平衡的计算不够准确和全面，尤其在气候敏感的高纬度极地地区，这种偏差可能会更大。 本论文旨在解决动态生态系统模型中的这个局限性问题。基于目前最先进的动态生态The Arctic and Subarctic regions are of particular importance to the global climate change and are now experiencing a climate warming that is higher than the global average. Around 50% of the global soil carbon is stored in high latitude soils, especially in permafrost and peatland soils. Permafrost thawing, speeding up the decomposition of previously frozen soil carbon, is expected to result in s

Popular Abstract in Swedish VIKTEN AV HETEROGENA JORDBRUKSMILJÖER FÖR GRÅSPARVEN Under de senaste 40 åren har vårt odlingslandskap genomgått kraftiga strukturella förändringar som en konsekvens av att jordbruket har intensifierats och effektiviserats. Dessa förändringar har möjliggjort en nödvändig, ökad produktion av spannmål och andra grödor men samtidigt har det haft förödande konsekvenser på dStrong declines of European farmland birds in recent decades are assumed to be caused by decreased food availability resulting from agricultural intensification and concomitant loss of farmland heterogeneity. One of the species suffering particularly strong declines in NW European countries is the house sparrow. In this thesis I investigated the importance of farmland land-use on house sparrow eco

The interferon inducible protein TRIM22 has been identified as a p53 target gene, with possible involvement in proliferation and differentiation of leukaemia cells. Here, the expression levels of TRIM22 during haematopoietic differentiation are characterised. Expression of TRIM22 correlates inversely to differentiation, as TRIM22 is highly expressed in CD34(+) human bone marrow progenitor cells, b

The Ncf1 gene was recently identified as a strong regulator of severe arthritis in rat. This finding was surprising, because the disease-promoting allele mediated a lower level of reactive oxygen species in NADPH oxidase-expressing cells. We have now investigated a splice mutation of the Ncf1 gene in B10.Q mice, causing a truncated and nonfunctional Ncf1 protein. We found that the mutated Ncf1 led

HAMLET (human alpha-lactalbumin made lethal to tumor cells) interacts with multiple tumor cell compartments, affecting cell morphology, metabolism, proteasome function, chromatin structure and viability. This study investigated if these diverse effects of HAMLET might be caused, in part, by a direct effect on the ATP synthase and a resulting reduction in cellular ATP levels. A dose-dependent reduc

Ekonomiska diskrepanser mellan länder och företag globalt skapar krav och behov för reglering av beviljande av bidrag eller statligt stöd på internationell nivå. I dess frånvaro skulle länder kunna ge vinster till produkter och kringgå konkurrens med otillbörlig förskjutning av varor som skulle ha behövt samma subventioner för att ha en ärbar chans att konkurrera med. Detta skulle bidra till ett öEconomic differences between countries and undertakings on a worldwide scale creates necessities for regulation on the granting of subsidies or State aid at the international level. In its absence, countries would be able to grant benefits to products and circumventing competition with unfairly displacement of goods that would have needed the same subsidies to have a decent chance at competing. Th

The European Border and Coast Guard was launched on October 6th, 2016. It was established through Regulation 2016/1624 and replaces the European Agency for the Management of Operational Cooperation at the External Borders of the Member States. The Agency is more known as Frontex. The objective with this thesis is to examine two problems in Regulation 2016/1624 that was addressed at the negotiatio

Fiberförstärkta plastkonstruktioners inverkan på risknivå ombord på stora passagerarfartyg Användning av fiberförstärkta plastkonstruktioner (FRP) inom den marina sektorn har blivit alltmer intressant ur ett hållbarhetsperspektiv. Problemet med FRP som byggnadsmaterial är att det är brännbart, vilket på grund av tradition och reglering gör det svårt att övergå från, det mer traditionella materialeThe main objective of this project was to determine how a FRP composite structure performs compared to a steel structure in regard to fire safety and risk level during an evacuation. More specifically the objective was to study how the differences in the thermal properties influence the smoke layer height, visibility and the temperature of the gases in the early stages of a fire. This was done by

Barnets bästa är den bärande principen i dagens barnrätt och härstammar ur såväl FN:s barnkonvention och föräldrabalken.1 Översiktligt går det att konstatera att de grundläggande tankarna om principen är att stärka respekten för barnets människovärde och integritet, samt som en etisk vägledning för alla enskilda bedömningar i mål som rör barnet. Det innebär att principen inte enbart ska tillämpas It is stated in both the UN Convention on the Rights of the Child and the Children and Parents code, that all actions concerning children shall have the best interests of the child as the primary consideration. According to the 6th chapter 2(a) section in the Children and Parents code, the best interest of the child shall be the primary consideration in all questions concerning the child, both in

This Bachelor’s degree project investigates how to create a modular chair system. It should let the consumer combine different parts to create a chair that fits their home, style and needs. The focus is on how a low number of parts can be used in different ways to create differentcombinations. It should also be easy to replace and recycle all parts when needed. This document shows the full design

HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is the first member in a new family of protein-lipid complexes with broad tumoricidal activity. Elucidating the molecular structure and the domains crucial for HAMLET formation is fundamental for understanding its tumoricidal function. Here we present the low-resolution solution structure of the complex of oleic acid bound HAMLET, derived

It is a common viewpoint that human rights, justice and law are interlinked with the institutions that we as a society create. Does that mean that, without institutions, there can be no rights? The purpose of this thesis is to determine whether or not there can be such a thing as human rights when there is no state to enforce them effectively. To achieve this purpose i have performed an analysis o

Ett vanligt förekommande mål bland såväl motionärer, idrottare, patienter och klienter är att öka muskelmassan, muskelhypertrofi. Ett antal litteraturöversikter har undersökt hur träning ska optimeras för att nå muskelhypertrofi, men ingen av dessa har fokuserat enbart på armbågsflexorer. Vi hypotetiserar att vad som är optimal dosering för att nå hypertrofi skiljer sig mellan olika muskelgrupper.

This thesis seeks to determine whether it is possible to strike a regulatory balance between satisfying the interests derived from individuals' right to privacy and states' defence of national security. However, the goal of this work is not to conduct an abstract analysis of the interrelations of these, sometimes conflicting, interests but to find practical solutions to a present issue, th
