Research student learning and supervision has become an increasing concern for many stakeholders inside and outside the universities. As a result, universities are in different ways trying to enhance doctoral education, often through activities aimed at research supervisors.In this paper we claim that research supervision and its relation to research student learning is poorly conceptualised in un

The aim of this doctoral study is to develop and implement a material model for granular materials. The course of this work was concentrated upon a non-associated plasticity model with yield surface and the flow potential expressed in terms of the mean stress p and the third stress invariants I3. The plastic work hardening in the model depends upon both plastic volumetric and deviatoric strain inc

Eukaryotic cells possess sensitive systems for the detection of microbes and microbial-derived products. Bacteria-eukaryotic cells contact triggers several signaling pathways, most of which are dependent on protein-protein interactions followed by phosphorylation, leading to activation of defense mechanisms. Yersinia bacteria have evolved different strategies to interfere with eukaryotic host defe

Summary form only given. The advanced resource connector (ARC), or the NorduGrid middleware, is an open source software solution enabling production quality computational and data grids. Since the first release (May 2002), the middleware is deployed and being used in production environments. Emphasis is put on scalability, stability, reliability and performance of the middleware. A growing number

Reduced urinary bladder capacity is a clinically significant problem. The surgical methods that have been available to treat this, such as urinary diversion or surgically augmenting the bladder by incorporation of intestinal segments, all have serious drawbacks. There is a need to understand how the smooth muscle of the intestine and bladder can interact when brought into close contact surgically,

Popular Abstract in Swedish Lera-vatten-systemet finns i stort sett överallt i vår omgivning. Syftet med denna avhandling är att identifiera och undersöka egenskaper hos leror som är av betydelse för deras inbördes växelverkan. Leror är sammansatta av två eller tre molekylära lager och får därför en relativt komplex fördelning av elektrostatiska laddningar. Denna fördelning förändras med olika betClays are the world’s most widely used natural material, however, little is known regarding the microstructure as well as the forces involved in clay-water interactions, and their influence on the swelling properties. The utilization of clay platelets is nowadays a key in a number of biological and industrial applications e.g. nuclear waste management. Bentonites from different natural sources an

Fruit and vegetable processors, faced with the challenge of gaining and maintaining a healthy position in the competitive fruit and vegetable sector, are optimising traditional processes towards product quality. Using frozen potatoes as a case study, the aim of this study was to evaluate the potential of improving the texture of potatoes by modifying the processing conditions. The texture of proce

Abstract Background. The plasma level of cystatin C is a better marker than plasma creatinine for successful aging. It has been assumed that the advantage of cystatin C is not only due to it being a better marker for glomerular filtration rate (GFR) than creatinine, but also because an inflammatory state of a patient induces a raised cystatin C level. However, the observations of an association be

Obese patients are prone to arterial hypertension, require more antihypertensive medications, and have an increased risk of treatment-resistant arterial hypertension. Obesity-induced neurohumoral activation appears to be involved. The association between obesity and hypertension shows large inter-individual variability, likely through genetic mechanisms. Obesity affects overall cardiovascular and

OBJECTIVE: To investigate whether Ritgen's maneuver decreases the risk of third- to fourth-degree perineal tears compared with simple perineal support. METHODS: A total of 1,623 nulliparous women in term labor, singleton pregnancy, and cephalic presentation were randomly assigned to Ritgen's maneuver or standard care. Ritgen's maneuver denotes extracting the fetal head, using one hand to pull the

Carotid endarterectomy (CEA) is a standardized surgical procedure and is the third most common vascular surgical procedure in Sweden. To improve the quality of pre- and postoperative care for patients undergoing elective CEA, a standardized care plan (SCP) was developed and implemented during Spring of 2007 at a vascular clinic in Sweden. In order to spread light on obstacles and possibilities in

In 2014 the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy (RAV) conducted a review and analysis of the state of knowledge on the duration of follow-up after exposure to human immunodeficiency virus (HIV). Up until then a follow-up of 12 weeks after exposure had been recommended, but improved tests and new information on early diagnosis motivated a re-evaluati

Salespeople’s work has always been regarded a crucial contributor to businesses’ value creation by researchers and practitioners alike. As tangible products are not at the core of interactions between salesperson and customer in the context of services-based or non-standardized markets, sales’ role is assigned greater influence in the understanding, creating and delivering of customer value. Under

Present work deals with reducing secondary losses in turbine cascade by using boundary layer fences in two ways. Firstly, to reduce the strength of vortex which is incident at the leading edge of airfoil and hence reduce the strength of horse shoe vortex, and secondly, to reduce the pressure gradient between the pressure side and the suction side in the flow passage region between airfoils. In pre

The main focus of this thesis has been to explore how the PFG NMR technique for diffusion measurements can be used to obtain useful information from various systems. The investigated systems have one thing in common; they belong to the general field of surface and colloid chemistry. The thesis is divided in two parts: one section is a summary and the other section contains four publications from

Popular Abstract in Swedish Denna avhandling undersöker hur vi använder visuell kontextinformation i samtal. Alla modeller över språkprocessning och kommunikation är ense om att visuell kontextinformation har en positiv nettoeffekt på förståelse och kommunikation. Trots detta är det inte klart genom vilka mekanismer denna kontextinformation verkar, eller om dessa mekanismer fungerar i situationer This dissertation is about the role of visual context information in communication. All accounts of language processing and communication agree that visual context is beneficial for understanding. Despite this, it is not clear through which mechanisms visual context works and whether these mechanisms also work in communication outside the lab setting. This dissertation aims to provide answers to t

BACKGROUND: Urothelial carcinomas originate from the epithelial cells of the inner lining of the bladder and may appear as single or as multiple synchronous tumors. Patients with urothelial carcinomas frequently show recurrences after treatment making follow-up necessary. The leading hypothesis explaining the origin of meta- and synchronous tumors assumes a monoclonal origin. However, the genetic

West Greenlandic Eskimo vowel spectra were investigated in carefully pronounced words and in continuous speech, and spectral differences were observed between the two situations. Spectra were compared in two consonantal environments - pharyngeal (uvular) and non-pharyngeal. In order to reconstruct vowel articulations, spectra were referred to nomograms from the three-parameter model of vowel artri
