Popular Abstract in Swedish I solens inre finns ett område där het, joniserad och mycket turbulent gas alstrar stora elektriska strömmar. Dessa strömmar genererar i sin tur ett starkt magnetfält som stiger upp till solens yta, fotosfären. I fotosfären uppstår en del intressanta magnetiska fenomen som till exempel solfläckar. Solfläckar är relativt svala områden som skapas då magnetfält hindrar denA solar magnetic field is continuously being created in the solar interior. As the field evolves outward through the solar atmosphere and into the enveloping heliosphere, it causes effects on a wide range of temporal and spatial scales. By studying and measuring these magnetic effects we gain extensive knowledge about solar magnetism and it also allows us to model and predict how solar activity is

It is contended in this thesis that the introduction of a legal regime with a rateless structure, subject only to market forces and a rebuttable statutory presumption as to where the rate line of conscience should be drawn, can provide a solution if the rate charged by pawnbrokers is to be regulated. The thesis also shows that a uniform pawn ticket issued as a negotiable document of title, and tra

Exoplanets have been observed at many stages of their host star's life, including the main-sequence (MS), subgiant and red giant branch stages. Also, polluted white dwarfs (WDs) likely represent dynamically active systems at late times. Here, we perform three-body simulations which include realistic post-MS stellar mass-loss and span the entire lifetime of exosystems with two massive planets, from

Kapitlet redogör för forskningen om coping och hur coping verkar i sammanhang där individerna använder religion i processen.

Are people strategically ignorant of the negative externalities their activities cause the environment? Herein we examine if people avoid costless information on those externalities and use ignorance as an excuse to reduce pro-environmental behavior. We develop a theoretical framework in which people feel internal pressure (“guilt”) from causing harm to the environment (e.g., emitting carbon dioxi

Popular Abstract in Swedish Inflammatoriska ledsjukdomar, innefattande bl.a. ledgångsreumatism, reumatoid artrit, och ledinflammation vid psoriasis, psoriasisartrit, är vanliga. I västvärlden lider cirka 1 procent av den vuxna befolkningen av reumatoid artrit (RA) medan psoriasisartrit (PsoA) är mindre vanlig. Ett kännetecken för dessa sjukdomar är att de medför en risk att ledernas vävnader brytsThe pathogenesis of inflammatory arthritides include synovial inflammation and joint tissue destruction. Tissue destruction has traditionally been regarded a consequence of inflammation, but recent observations indicate that the processes are not always closely linked and may proceed uncoupled. The ultimate target organs for the destructive process are articular cartilage and bone. This thesis f

Popular Abstract in Swedish Tjocktarmcancer är en av de vanligaste cancerformerna i västvärlden. I Sverige drabbas årligen ca 5000 människor. Ungefär 10% av fallen går att härleda till ärftliga faktorer medan den övervägande delen orsakas av miljöfaktorer. Kända riskfaktorer är fysisk inaktivitet, fetma och rökning. Risken för cancer påverkas dock mest av den kost vi äter. Allmänt kan sägas att enSphingomyelin (SM) is present both in eucaryotic cells and the diet. Sphingomyelinase (SMase) hydrolyses SM and generates ceramide that has been implicated in the regulation of cell growth, differentiation and apoptosis. Previously a SMase with alkaline pH optimum was identified in the intestinal tract. The thesis studied the distribution pattern, the species difference and the clinical implicatio

The management of construction tolerances is a necessary and routine part of the construction activity and is normally brought to our attention only when failures are reported. In a study of tolerance management, the authors found widespread evidence of the same failures and the reasons for them. There seems to be no shortage of experience of the effects of failures in tolerances or of knowledge a

Boken handlar om Karl Knutsson, en av centralgestalterna i 1400-talets svenska historia. Han var riksföreståndare en gång och kung tre gånger, dessutom mångårig makthavare i Finland, härskare över en del av norra Polen (Putzig), herre över sjörövare på Östersjön och en förgrundsgestalt i den svenska politiska propagandans historia. I boken skildras Karl Knutssons liv från vaggan till graven. Det ä

We describe the implementation of a gated resonant tunneling diode and its application in a wavelet generator. The GaAs-based device is fabricated by embedding a metal gate directly above a double barrier heterostructure with a peak current of 120 kA/cm2. The gate is used to modulate the tunneling current via the Schottky depletion around the buried metal. We integrate the gated tunnel diodes in o

Report of a trans-european research project that has taken place over two years (1999 – 2001) involving 15 partners from 10 EU countries, one EFTA and one non-EU country, and a European federation. On the basis of empirical and conceptual work the project proposes a common framework for education and training with a duration of six years. It is intended to be used to: Assess the adequacy of existi
