Structural Retrofitting of Reinforced Concrete Beams using Carbon Fibre Reinforced Polymer

This thesis details experimental work and finite element simulations of reinforced concrete beams retrofitted with carbon fibre reinforced polymer (CFRP). The objectives of this study were to investigate the behaviour of retrofitted beams experimentally, develop a finite element model describing the beams, verifying the finite element model against the experimental results and finally investigatin

Combustion Chamber Wall Temperature Measurement and Modeling During Transient HCCI Operation

In this paper the combustion chamber wall temperature was measured by the use of thermographic phosphor. The temperature was monitored over a large time window covering a load transient. Wall temperature measurement provide helpful information in all engines. This temperature is for example needed when calculating heat losses to the walls. Most important is however the effect of the wall tempera

Rho-kinase signalling regulates trypsinogen activation and tissue damage in severe acute pancreatitis.

Background and purpose: Severe acute pancreatitis (SAP) is characterized by trypsinogen activation, infiltration of leucocytes and tissue necrosis but the intracellular signalling mechanisms regulating organ injury in the pancreas remain elusive. Rho-kinase is a potent regulator of specific cellular processes effecting several pro-inflammatory activities. Herein, we examined the role of Rho-kinase

Delineating the cellular pathways of hematopoietic lineage commitment.

The prevailing model for adult hematopoiesis postulates that the first lineage commitment step results in a strict separation of common myeloid and common lymphoid pathways. However, the recent identification of granulocyte/monocyte (GM)-lymphoid restricted lymphoid-primed multipotent progenitors (LMPPs) and primitive common myeloid progenitors (CMPs) within the "HSC" compartment provide compellin

Electron correlation effects in the double ionization of He

The double-ionization yield of He is calculated with a one-dimensional fully correlated two-electron model for the low laser frequency of recent experiments. Results for a higher laser frequency also indicate a comparable very high double-ionization yield for sufficiently short pulses. It is shown that the Hartree-Fock approximation fails dramatically in describing the two-electron dynamics. Also,

Variation of breast cancer risk among BRCA1/2 carriers

CONTEXT: The risk of breast cancer in BRCA1 and BRCA2 mutation carriers has been examined in many studies, but relatively little attention has been paid to the degree to which the risk may vary among carriers. OBJECTIVES: To determine the extent to which risks for BRCA1 and BRCA2 carriers vary with respect to observable and unobservable characteristics. DESIGN, SETTING, AND PARTICIPANTS: Probands

Is the volume of domestic patenting in Vietnam a cause for concern? : An exploration of the issue and its policy implications

This paper examines the assumption that the volume of domestic patenting in Vietnam is too low and needs to be expanded. The structure and state of development of the Vietnamese economy and a set of relevant systems - including the Science and Technology (S&T) System, the Intellectual Property System, the National Innovation System (NIS), and the Science, Technology and Innovation (STI) Policy

Entrepreneurial Dynamics and Acquisitions of New Technology-Based Firms

Popular Abstract in English The aim of this thesis is to investigate the evolution of new technology-based firms (NTBFs) based on solid empirical material for the Swedish economy. The focus on this thesis is exploring the role of acquisition by incumbent firms in the evolution of NTBFs. The findings of this thesis show that selection is a core feature in the evolution of NTBFs. NTBFs experience a The aim of this thesis is to explore the evolution of new technology-based firms (NTBFs) based on solid empirical material for the Swedish economy. NTBFs are argued to be one important type of entrepreneurial firms that contribute to technology change, knowledge spillovers, and economic growth. However, our knowledge concerning how NTBFs exert their technological and economic influences is far fro

Time-frequency analysis of atrial fibrillation

This licentiate thesis, containing two papers, is in the field of biomedical signal processing with main focus on signal processing of the ECG in patients with atrial fibrillation (AF). The two papers deal with different aspects of characterization of the f waves during atrial fibrillation. In the fist paper several measures designed to extract features of the f waves are evaluated with respect to
