Agricultural ecosystems are important for regulating terrestrial hydrological and carbon cycles. Hydrological and carbon processes in agricultural ecosystem models are complex due to interactions between parameters. It is therefore crucial to identify parameter sensitivity before a process-based model is applied for simulations and predicti
Pheromones are intraspecific chemical signals serving as a ubiquitous form of communication, particularly among insects. Female sex-pheromone signals act as the core constituent in the specialized odour-mediated moth mate-recognition system. Female moths typically release multicomponent mixtures of alcohols, aldehydes or acetates. The biosynthetic machinery controlling pheromone production compris
The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate th
Ciliate assemblages play a significant role in the microbial food web. The effects of environmental temperature on assemblage composition may be influenced by abiotic factors such as seasonality and disturbance, but the effects of temperature on ciliate assemblages found on different substrata have not been explored. Sandy bottoms and submerged rocks harbour dissimilar ciliate assemblages, and it
Wireless adhoc networks transmit information from a source to a destination via multiple hops in order to save energy and, thus, increase the lifetime of battery-operated nodes. The energy savings can be especially significant in cooperative transmission schemes, where several nodes cooperate during one hop to forward the information to the next node along a route to the destination. Finding the b
Different types of colonic dysganglionosis, and in particular intestinal neuronal dysplasia (IND) have been blamed for certain postoperative complications after surgery for Hirschsprung's disease (HD). We prospectively assessed colon innervation above the aganglionic zone (AZ) before proceeding to pull-through (PT) in order to rule-out IND as a cause of those complications. We first used a two-sta
CONTEXT: Oral once-daily dual-release hydrocortisone (DR-HC) replacement therapy has demonstrated an improved metabolic profile compared to conventional 3-times-daily (TID-HC) therapy among patients with primary adrenal insufficiency. This effect might be related to a more physiological cortisol profile, but also to a modified pattern of cortisol metabolism. OBJECTIVE: This work aimed to study cor
Background: Childhood cancer survivors (CCS) are at an increased risk for cardiovascular diseases (CVD). It was the primary aim of this study to determine different measures of cardiac, carotid, lipid, and apolipoprotein status in young adult CCS and in healthy controls. Methods: Cardiac and common carotid artery (CCA) structure and function were measured by ultrasonography. Lipids and apolipoprot
The Soma and Neurite Density Imaging (SANDI) three-compartment model was recently proposed to disentangle cylindrical and spherical geometries, attributed to neurite and soma compartments, respectively, in brain tissue. There are some recent advances in diffusion-weighted MRI signal encoding and analysis (including the use of multiple so-called ’b-tensor’ encodings and analysing the signal in the
I denna avhandling beskrivs processesen att implementera och optimisera metoder inom kvantitativ magnetresonansomografi (MRT) på en fältstyrka av 7 T. Metoderna är baserade på gradientekon med påtvingad transversell urfasning (spoiling) och applicerade på den mänskliga hjärnan i syfte att avbilda i huvudsak tre olika MR-parametrar: Den longitudinella relaxationstiden (T1), magnetization transfer Quantitative MRI (qMRI) refers to the process of deriving maps of MR contrast parameters, such as relaxation times, from conventional images. If the qMRI maps have a high degree of precision and a low degree of bias, they can be compared longitudinally, across subjects, and (ideally) between measurement protocols and research sites. They also provide a more direct biophysical interpretation of the
What does a sustainability project look like in the 21st century? Not the glossy version, but the naked truth? Tired of manicured, over-theorised accounts of the ‘musts’ and ‘shoulds’ of sustainability transitions, we got to the bottom of things; actually, to the very bottom of the project hierarchy: the individual. Our point of departure is that projects are nothing but temporarily interconnected
Anticipatory and predictive models are becoming very important features of robot systems. This thesis investigates some aspects of predictive modeling. Is prediction always a good thing? How important is it to anticipate what will happen in the future? Is it better to anticipate far into the future or to focus on the next few seconds? What are the requirements for predictive models? Predictive mod
Popular Abstract in Swedish Den sydafrikanske författaren J. M. Coetzee, nobelpristagare 2003, är en komplex författare som räknas till en av samtidens största. Han har en unik politisk hållning i sina romaner och vägrar konsekvent att ge några enkla lösningar, istället drar han in läsaren och tvingar henne att bli delaktig i verkens problematik. I denna studie, den första avhandlingen på svenska This dissertation is a study of In the Heart of the Country (1977), Waiting for the Barbarians (1980), Age of Iron (1990), Disgrace (1999), Diary of a Bad Year (2007), and Summertime (2009) written by J. M. Coetzee. The aim of the dissertation is to analyze these works of fiction using four postcolonial aspects that function as consistent themes in the novels. The aspects are; the relationship bet
Popular Abstract in Uncoded languages A modern tartószerkezeti szabványok általában két fő követelményt támasztanak a tartószerkezetekekkel, illetve szerkezeti elemekkel szemben. Az egyik a tönkremenetellel szembeni biztonsághoz, míg a másik a használhatósághoz kapcsolódik. A szerkezeti használhatóság a tartószerkezet azon képessége, hogy tervezett szerepét élettartams során folyamatosan betöltse.In many design situations the acceptable performance of structures is defined by serviceability requirements. To estimate the probability of serviceability failure three main design aspects should be considered: (1) the relevant exposures, (2) the structural response and (3) the performance criteria. This thesis presents background information and new findings on structural serviceability related
Background: The current lack of knowledge among entrepreneurs to manage the e-commerce market has created an increased need for incubator activities and the support that incubators can assist entrepreneurs with. Incubators intend to contribute with support for companies by assisting with various services where the success of business development can lie in different combinations of these services
Tvister som rör vårdnad av barn ger ofta upphov till svåra bedömningsfrågor för domstolarna. Ofta går svaren inte att finna enbart i lagen utan domstolen måste även beakta sociala utredningar. I 6 kap. 2 a § FB framgår att barnets bästa ska vara avgörande för alla beslut om vårdnad, boende och umgänge. I samma paragraf framgår det att barnets kontakt med båda föräldrar ska beaktas i bedömningen avDisputes involving the custody of children often poses complex judicial questions for the court. Often, answers cannot be found only in the law and therefore the court must also take social investigations into account. The law states that the best interests of the child must be decisive for all decisions regarding custody, residence, and visitation. It also states that the child's contact with
This thesis examines the social unfolding of the recent deplatformization of the far-right extremes on Telegram. Leaving prior approaches to moderation behind, this study asks questions around how moderation imprints itself on the complex terrain of meaning and practice, interacts with intensified reflexiveness of the social agents, and leaves affected collectivities changed in unanticipated ways.
Samhall har utfört sitt kärnuppdrag, att utveckla och rehabilitera personer med funktionshinder, sedan innan Sverige gick med i EU, och det är inte förvånade att det finns frågetecken kring hur den merkostnadsersättning företaget erhåller förhåller sig till EU:s statsstödsregler. De EU-rättsliga kraven på stöd som medlemsstaterna utger har vidare utvecklats och preciserats under de senaste åren, sSamhall has been carrying out its main assignment to provide development opportunities for and rehabilitate people with disabilities since before Sweden became a member of the EU. With that in mind it is hardly surprising that there are questions as to whether the aid that Samhall receives for carrying out this assignment complies with the EU state aid laws. In recent years the concept services of
This thesis aims at developing and evaluating a model for high frequency foreign exchange data, that beats the TWAP benchmark the majority of the time. This is done by dividing the total order time into smaller time buckets and trading a smaller quantity of the total order volume in each bucket. The second purpose of the thesis is to determine if there is an optimal bucket size in which to trade i
