Until recently, the general level of detail in full car crash models has not allowed a physical modeling of rubber bushings with solid elements. This is partly because of the difficulty in modeling the complex characteristic of rubber, but also due to limited understanding of the mechanical properties of rubber materials. The main focus of this Master’s thesis project is to develop a new and im

A rising problem within electronics today is that, since the frequencies have increased dramatically, it is now very difficult to measure signals. If a traditional probe is used, then the direct contact will destroy the signal. The general idea behind this master thesis project is to make use of the crosstalk between transmission lines to create non contact test points. This thesis aims to evaluat

Klimatmönstren världen över förändras och med dessa den globala distributionen och mängden av landbundet kol, dvs vegetationen som bland annat nyttjas som mat och fiber. Också I sig självt en viktig faktor i klimatets utveckling genom dess roll i energi- och vattenkretsloppen. Vetskap om kvantitet och distribution av landbundet kol och hur detta förändras är en viktigt del av arbetet i att förstå The climatic patterns of the world are changing and with them the spatial distribution of global terrestrial carbon; the food and fiber of the world and in itself an important factor in the changing climate. Knowledge of how the terrestrial carbon stock is changing, its distribution and quantity, is important in understanding how the patterns of the world are changing and large scale models using

In this Master Thesis different methods for measuring and evaluating surface textures have been investigated and evaluated. A method for digitizing textures called photometric stereo have also been studied. The purpose has been to find methods that can replace or supplement the current method of visual inspection used for surface texture studies by IKEA of Sweden. The suggested methods are going t

Titel: Sommar, Sol och Service– En studie om säsongspersonalens förutsättningar för att leverera servicekvalitet Nivå: Kandidatuppsats Institution: Institutionen Service Management - Turism, Campus Helsingborg, Lunds Universitet Författare: Emelie Lundgren & Veronica Larsson Handledare: Ulrika Westrup Bakgrund och problem: Turismindustrin präglas av säsongsvariationer vilket får konsekvenser f

Den nya mediemiljön med sociala medier gör det möjligt att konstruera och styra mediebilden av sig själv, men ett ständigt informationsflöde bidrar till en kamp om uppmärksamheten. Det finns flertalet exempel på personer som ständigt figurerar i medierna och som spelar spelet om respekt i offentligheten, men vissa frotterar sig i finrummen medan andra inte gör det. Hur kommer detta sig? Studiens m

Users of Business Intelligence (BI) systems have started to demand more flexible systems in which they could be empowered to serve themselves – self-service BI. In this paper we aim at explaining how such development influences designers of BI solutions and how it impacts the design situation. To say something about this we adapted the PACT (People, Activity, Context, Technology) framework on the

We propose two fundamental principles of epistemological accountability with critical methodological implications for studies designed to measure, assess, and/or profile human psychosocial resilience. Firstly, researchers involved in human psychosocial resilience studies owe it to the individuals and communities that they engage to disclose their motives and possible misreadings of the situations

Background: One-pot multi-step biocatalysis is advantageous over step-by-step synthesis as it reduces the number of process operation units, leading to significant process intensification. Whole-cell biocatalysis with metabolically active cells is especially valuable since all enzymes can be co-expressed in the cell whose metabolism can be exploited for supply of co-substrates and co-factors. Resu

The effect of glucose and oxygen limitation on the growth and fermentation performances of Dekkera bruxellensis was investigated in order to understand which factors favour its propagation in ethanol or wine plants. Although D. bruxellensis has been described as a facultative anaerobe, no growth was observed in mineral medium under complete anaerobiosis while growth was retarded under severe oxyge

This paper analyzes the impact of intermarriage on the economic integration of immigrants in Sweden, measured by annual earnings. We use longitudinal register data for the period 1990-2009 for the total population of immigrant men born 1960-1974. The results reveal large intermarriage premiums, but overall this seems to be a result of selection effects as most of the premium is visible already at

Rheumatoid arthritis (RA) is a highly disabling disease affecting all structures of the joint. Understanding the pathology behind the development of RA is essential for developing targeted therapeutic strategies as well as for developing novel markers to predict disease onset. Several molecules normally hidden within the cartilage tissue are exposed to complement components in the synovial fluid u

A concept for time-sensitive optical detectors is described that shows how to confirm whether the detection device is operating in the linear response regime. By evaluating the recorded time decay of a thermographic phosphor, even weak saturation effects far from obvious situations can be identified and further related to either optical or electrical saturation. The concept has been validated by r

Assays detecting antigen (Ag)-specific T-cell responses in immune-mediated processes are increasingly employed to understand disease pathogenesis and "immune staging". The quantity and quality of starting peripheral blood mononuclear cell (PBMC) preparations are important factors in the performance of such assays. We therefore compared final PBMC yield and function by modifying parameters at the b

A means for noninvasive measurement of transverse and longitudinal characteristics of bunched beams in synchrotrons has been developed based on high sensitivity slotted waveguide pickups. The pickups allow for bandwidths exceeding hundreds of MHz while maintaining good beam sensitivity characteristics. Wide bandwidth is essential to allow bunch-by-bunch measurements by means of a fast gate. The Sc

The biothiols sensing mechanism of (E)-7-(diethylamino)-3-(2-nitrovinyl)-2H-chromen-2-one (DCO) has been investigated using the density functional theory (DFT) and time-dependent DFT methods. The theoretical results indicate that the excited-state intermolecular hydrogen bonding (H-B) plays an important role for the biothiols sensing mechanism of the fluorescence sensor DCO. Multiple H-B interacti

Background: Proteins can be used in drug delivery systems to improve pharmacological properties of an active substance. Differences in pH between tissues can be utilized in order to achieve a targeted drug release at a specific location or tissue, such as a tumor. The enamel matrix protein amelogenin has a pH dependent solubility profile and self-assemble to form aggregates at neutral pH. This cou
