The Seebeck coefficient, a key parameter describing a material's thermoelectric performance, is generally difficult to measure, and no intrinsic calibration standard exists. Quantum dots and single electron tunneling devices with sharp transmission resonances spaced by many kT have a material-independent Seebeck coefficient that depends only on the electronic charge and the average device temperat

Syftet med detta projekt är att göra uppdaterade och utvecklade livscykelanalyser för biodrivmedel som är aktuella i Sverige idag. Fokus ligger på att göra så transparenta och relevanta jämförelser som möjligt och att lyfta fram de steg i livscykeln som signifikant påverkar respektive biodrivmedels miljöprestanda. I studien görs känslighetsanalyser som visar effekterna av t ex framtida förändrade

Background: To study motor ability at seven years of age in children treated for idiopathic clubfoot and its relation to clubfoot laterality, foot status and the amount of surgery performed. Methods: Twenty children (mean age 7.5 years, SD 3.2 months) from a consecutive birth cohort from our hospital catchments area (300.000 inhabitants from southern Sweden) were assessed with the Movement Assessm

Öppna digitala Iärresurser (Open Educational Resources, OER) är undervisnings-, lärande- och forskningsmaterial som finns tillgängliga på Internet. Resurserna är öppna och fria och vanligen under creative commons licenser (cc). Beroende på licens tillåts resurserna att användas, återanvändas, spridas och även säljas öppet och fritt. Internationellt är OER-rörelsen mycket stark. I Sverige går därem

To assess how synergies between climate warming and increased concentrations of humic substances ("brownification") will affect rotifer community establishment in spring, we conducted a mesocosm experiment where we combined a 3 degrees C temperature increase with a doubling in water color, changes corresponding to modeled projections for the coming 25-75 yr. We also performed a complementary preda

BACKGROUND: Hypothermia may be accidental or therapeutic. Therapeutic hypothermia is increasingly used as treatment for various conditions, e.g., neuroprotection after cardiac arrest. Hypothermia leads to an impairment of the coagulation system, but the degree of impairment has been difficult to determine. Most studies have been performed on plasma instead of whole blood. We therefore evaluated wh

In this article, we perform a robust analysis of the determinants of U.S. swap spreads using a wide range of theoretically motivated candidate factors. We conduct an analysis by taking into consideration the interdependence between the candidate factors, as well as the time frequency under which the factors affect the spread. We find that the suggested variables can to a fair degree explain moveme

Understanding the processes generating fluctuations of natural populations lies at the very heart of academic ecology. It is also very important for applications such as fisheries management and pest control. We are interested in the effect of harvesting on population fluctuations and for that purpose we develop and analyze an age-structured model where recruitment is a stochastic process and the

This naturalistic study presents outcomes for three therapy types practiced in psychiatric public health care in Sweden. Data were collected over a 3-year period at 13 outpatient psychiatric care services participating in the online Quality Assurance of Psychotherapy in Sweden (OAPS) system. Of the 1,498 registered patients, 14% never started psychotherapy, 17% dropped out from treatment, and 36%

Popular Abstract in Swedish Alltsedan expansionen av den högre utbildningen tog fart i Sverige, i slutet av 60-talet, har universitet och högskolor arbetat för att utveckla utbildningskvaliteten. Detta har bland annat gjorts genom satsningar på policys som reglerar exempelvis arbete med kursvärderingar, mångfald, och kurs- och utbildningsplaner. Satsningar har också gjorts på pedagogisk utbildningThe focus in this thesis is to explore theoretical perspectives and strategies for academic development, particularly in a research-intensive university. The purpose is to investigate academic development that aims to support and influence individual academic teachers and groups of teachers, in the different social collegial contexts that they work in, here called microcultures. Building on litera

A measurement of the differential cross-section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy root s = 7 TeV is presented. The measurement covers the pseudorapidity ranges vertical bar eta vertical bar < 1.37 and 1.52

The biodegradability of dissolved organic carbon (DOC) in different fractions from the forest floor was studied. Soil leachate (SI, the soil solution in macropores which is freely drained from forest floor after rainfall), the soil matrix solution (SMS, the soil solution in meso-/micropores of the soil matrix), and soil water extracts (SWE) from two different beech forest floors were compared. Zer

Inflammation is a response to injury or pathogen invasion. A large proportion of the bodie's immune system is centred in the gastrointestinal tract (GI). Prolonged inflammatory conditions of the GI have been suggested to increase the risk for developing colon cancer. The cysteinyl leukotrienes (CysLTs), LTC4, LTD4 and LTE4 are inflammatory mediators that can bind to four known receptors, two of wh

In recent years, the 'river basin as a management unit' approach has been adopted as a solution to water management. The situation between Swaziland, Mozambique and South Africa regarding managing the water resources of the Incomati, Maputo, and Umbeluzi shared river basins is an interesting case that might need a different approach. These rivers flow downstream to the Maputo estuary where their w

We present a conceptual model for supercontinent cycles in the Proterozoic-Phanerozoic Eons. It is based on the repetitive behavior of C and Sr isotopes in marine carbonates and U–Pb ages and εHf of detrital zircons seen during the Neoproterozoic-Paleozoic and Paleoproterozoic Eras, respectively. These records are considered to reflect secular changes in global tectonics, and it is hypothesized th

Popular Abstract in Swedish Socioekonomiska mönster av övervikt och fetma i Skåne, Sverige I världen idag är fetma och övervikt ett av de största hoten mot människors goda hälsa. Den här avhandlingen har försökt beskriva och öka kunskapen om hur olika faktorer, som levnadsvillkor och levnadsvanor, bidragit till ökningen av övervikt och fetma i befolkningen. Övervikt och fetma ökar risken för en rOverweight and obesity are major social and public health concerns globally. The obesity epidemic is caused by a widespread chronic energy imbalance between high-energy intake and low-energy expenditure, but this mechanism appears to be modified by a number of other biological, behavioral, and social factors that interact in a complicated manner. It has become a great challenge to understand the e

Participating in physical activity promotes physical and mental health. Children with physical disabilities are not as physically active as other children. They tend to participate in lower intensity physical activity, choose more passive activities with less variety and have more sedentary time. The overall aim of this thesis was to gain knowledge about participation in physical activities, to i

Multifunctional proteins, which play a critical role in many biological processes, have typically evolved through the recruitment of different domains that have the required functional diversity. Thus the different activities displayed by these proteins are mediated by spatially distinct domains, consistent with the specific chemical requirements of each activity. Indeed, current evolutionary theo
