A general economic model for manufacturing cost simulation

The described technical-economic model clarifies the influence of different production technological factors on the processing cost of a part. Influential factors can be weighted against each other, which leads to different production development scenarios and their effects on the processing cost can be studied. This implies a way to generate a basis of decision by which a company can base their p

Challenges in Designing Resilient Socio-technical Systems: A Case Study of Railway Tunnel Projects

This paper presents a case study of decision-making at the design stage of a socio-technical system where resilience at the global level of the system was constrained by the local perspectives adopted by the different stakeholders. The study is based on interviews with key decision-makers involved in the design stage of six railway tunnel projects in Sweden. The results show that differences in ro

Hållbar utveckling, strategier på program- och kursnivå

Efter HSVs utvärdering av CI- utbildningarna fick högskolorna ett tydligt uppdrag att vid uppföljningen redovisa hur hållbar utveckling kommer in i utbildningarna. I planeringsförutsättningarna för de 5-åriga civilingenjörsutbildningarna vid LTH finns kravet på examination av minst 6 hp inom området.

CFD Investigation of Swirl-stabilized Flexi-fuel Burner Using Methane-air Mixture for Gas Turbines

Combustion modeling based on a multi-step global reaction mechanism [1] is applied to CFD (Computational Fluid Dynamics) analysis of a scaled swirl-stabilized 4th generation premixed DLE (Dry Low Emission) burner for gas turbines. The flexi-fuel burner consists of a MAIN premixed flame, a premixed PILOT flame and a confined RPL (Rich Pilot Lean) flame. Both steady-state RANS (Reynolds Averaged Nav

A Model for Vulnerability Analysis of Interdependent Infrastructure Networks

The technical infrastructures of the society are becoming more and more interconnected and in-terdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Distur-bances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly impo

Deregulation of the Wilms' tumour gene 1 protein (WT1) by BCR/ABL1 mediates resistance to imatinib in human leukaemia cells

The Wilms' tumour gene 1 (WT1) protein is highly expressed in most leukaemias. Co-expression of WT1 and the fusion protein AML1-ETO in mice rapidly induces acute myeloid leukaemia (AML). Mechanisms behind expression of WT1, as well as consequences thereof, are still unclear. Here, we report that the fusion protein BCR/ABL1 increases expression of WT1 mRNA and protein via the phosphatidylinositol-3

Treatment of Uncertainty in Risk Based Regulations and Standards for Risk Analysis

The role of quantitative risk analysis as a foundation for decision making, regarding hazardous activities and establishments, has gained increased importance during the last decades. When performing a quantitative risk analysis, a wide range of uncertainties will inevitably be introduced during the process. The impact of these uncertainties must somehow be addressed if the analysis is to serve as

A Brief Overview of Some Methods and Approaches for Investigating Interdependencies in Critical Infrastructures

This chapter presents methods for analysing interdependencies in critical infrastructures. In general, there are three groups of methods for analysing interdependencies; (1) conceptual, (2) model and simulation and (3) empirical and knowledge-based approaches. Examples of methods belonging to these groups are presented. The latter part of the chapter discusses challenges related to modelling, focu

The properties of α-synuclein secondary nuclei are dominated by the solution conditions rather than the seed fibril strain

Amyloid fibrils of α-synuclein (α-syn) are a component of Lewy bodies, the characteristic hallmark of Parkinson's disease. Amyloid fibrils arise through primary nucleation from monomers, which in the case of α-syn is often heterogeneous, followed by the growth of the nuclei by monomer addition. Secondary nucleation corresponds to the formation of new fibrils facilitated by pre-existing fibrils. Wh

Red Cell Distribution Width is Associated with Future Incidence of Abdominal Aortic Aneurysm in a Population-Based Cohort Study

Red cell distribution width (RDW) has been suggested to have a predictive potential for several cardiovascular diseases, but its association with abdominal aortic aneurysm (AAA) is unknown. We examined whether RDW is associated with the risk of AAA among 27,260 individuals from the population-based Malmö Diet and Cancer Study cohort. Data of baseline characteristics were collected during 1991–1996

Secondary Nucleation in Amyloid Formation

Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive. This thesis and the work herein is part of an ongoing effort to map out the aggre
