Individuell betygsättning av grupparbeten inom högre utbildning

Det finns många fördelar med att låta studenter vid högre utbildning gruppvis genomföra projektarbete med öppna frågeställningar. Det finns emellertid problem med att sätta individuella betyg i en kurs som till stor del examineras genom det gruppvisa projektarbetet. I kursen EEMA01 Medicinteknisk design ges valet av undervisningsform naturligt av lärandemålens karaktär men betygssättningen böravsp

Lessons of Feedback in Higher Education in Sweden

Lessons learned in the feedback process are atwo-sided coin that ultimately guide the PhD candidatetowards becoming an independent researcher as well aseducating “reader/docents” in their role as supervisor.Building on a brief literature review, observations from 14interviewed PhD candidates were reflected upon and these arethe suggested lessons learned. The study’s preliminary findingssuggest tha

Developing a framework for characterising cascading failures in past events to inform emergency response decisions

Increasing interdependencies between critical infrastructures have made these systems more effective, but also more susceptible to cascading failures. In order to reduce the likelihood and consequences of cascading failures, it is essential to develop tools that support incident commander decisions so that an initial failure does not spread to other infrastructures. Here, a framework for generatin

''Studenterna lär sig det de får arbeta med. Ge dem ett bra arbetsmaterial!''

En viktig faktor för studenternas lärande i en kurs är uppgifterna de arbetar med. Idealt ska de träna studenterna på olika kompetenser, belysa teorin på olika sätt och samtidigt motivera och väcka intresse. Sedan några år tillbaka använder vi ett omfattande arbetsmaterial ''Räkna med variation'' för att undervisa i grundläggande sannolikhetslära och statistisk inferens. Vi kommer att presentera a

Metallopeptidase inhibitor 1 (TIMP-1) promotes receptor tyrosine kinase c-Kit signaling in colorectal cancer

Colorectal cancer (CRC) is the third most prevalent cancer worldwide causing an estimated 700 000 deaths annually. Different types of treatment are available for patients with advanced metastatic colorectal cancer, including targeted biological agents, such as cetuximab, a monoclonal antibody that targets EGFR. We have previously reported a study indicating multiple levels of interaction between m

Interactions and coherences in electron transport through serially coupled quantum dots

This thesis is considering various aspects of electronic transport through quantum dots, with the focus on two or three dots coupled in series.In paper I, we study the impact of electron-electron interactions on transport in a system of triple quantum dots with spin. We show that due to electron-electron scattering processes, transport is possible beyond the common single-particle transmission cha

Improved Tracking Performance in High Frame Rate Imaging Using Iterative Phase Tracking

High frame rate ultrasound imaging is necessary to enable tracking of rapid dynamic events such as the carotid pulse wave velocity. Several studies have shown that it is feasible to use motion tracking methods that are applied on standard ultrasound frame rates also on very high frame rates. However, few studies have addressed the issue of accumulated tracking errors over vast numbers of frames du

Numerical Investigation and Estimating Correlation of Micromixing Performance of Coaxial Mixers

In view of the significance, complexity, and difficulty of micromixing in viscous system, coaxial mixers with wide adaptability to viscosity are first combined with micromixing. The effects of feeding position, rotation mode, and impeller type on the micromixing performance of coaxial mixers are investigated numerically with the standard engulfment model and eddy dissipation concept model, and a d

Long-term follow-up of patients undergoing standardized bicycle exercise stress testing : new recommendations for grading of exercise capacity are clinically relevant

Introduction: A new grading of exercise capacity during bicycle stress testing has been proposed in Sweden based on the new reference material (‘the Kalmar material’), which has not been validated. We aimed to examine the prognostic information of the new grading of exercise capacity during exercise stress testing. Methods: Data on all bicycle exercise tests performed at the Department of Clinical

Electrical control of spins and giant g-factors in ring-like coupled quantum dots

Emerging theoretical concepts for quantum technologies have driven a continuous search for structures where a quantum state, such as spin, can be manipulated efficiently. Central to many concepts is the ability to control a system by electric and magnetic fields, relying on strong spin-orbit interaction and a large g-factor. Here, we present a mechanism for spin and orbital manipulation using smal

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists to avoid the common errors that often undermine immunological data. Notably, there are comprehensive sections of all major immune cell types with helpful Tables detailing phenotypes in mu

Epigenome-wide association study of incident type 2 diabetes in a British population : EPIC-Norfolk study

Epigenetic changes may contribute substantially to risks of diseases of aging. Previous studies reported seven methylation variable positions (MVPs) robustly associated with incident type 2 diabetes mellitus (T2DM). However, their causal roles in T2DM are unclear. In an incident T2DM case-cohort study nested within the populationbased European Prospective Investigation into Cancer and Nutrition (E

Road tunnel fire safety and risk: a review

A review concerning road tunnel fire safety and risk is presented. In particular different perspectives and methodson safety and risk are discussed. Road tunnel fire safety usually involves high uncertainty and high-stakes decisions.Thus, a wider group of stakeholders and different types of knowledge should be included in the fire safety analysisand evaluation, than what is required by technical r

Comment on "The global tree restoration potential"

Bastin et al (Reports, 5 July 2019, p. 76) claim that 205 gigatonnes of carbon can be globally sequestered by restoring 0.9 billion hectares of forest and woodland canopy cover. Reinterpreting the data from Bastin et al, we show that the global land area actually required to sequester human-emitted CO2 is at least a factor of 3 higher, representing an unrealistically large area.

Optical Diagnostics for Quantitative Potassium Chemistry in Biomass Thermochemical Conversion Processes

Biomass is an essential sustainable and carbon-neutral energy source. Through thermochemical conversion processes, such as combustion and gasification, biomass can generally be used in boilers to provide heat and/or power. Biomass fuels contain varying amounts of potassium, chlorine and sulfur. The release of these elements, especially in the form of potassium chloride (KCl), in the thermal conver
