In solid mechanics, linear structures often exhibit (local) nonlinear behavior when close to failure. For instance, the elastic deformation of a structure becomes plastic after being deformed beyond recovery. To properly assess such problems in a real-life application, we need fast and multi-query evaluations of coupled linear and nonlinear structural systems, whose approximations are not straight

This study evaluates a new pedagogic approach implemented in material courses for product design students at bachelor level education. Material education within the field of design education at technical faculties has, in general, a strong technical focus, e.g. selecting materials with predominant focus on engineering properties of materials. Product design education at a bachelor level need to of

In line with cognitive semiotics, this paper suggests a synthetic account of the important but controversial notion of narrative (in street art, and more generally): one that distinguishes between three levels: (a) narration, (b) underlying story, and (c) frame-setting. The narrative potential of street art has not yet been considerably studied in order to offer insights into how underlying storie

This work establishes a computational framework for the quantification of the effect of uncertainty of material model parameters on extremal stress triaxiality and Lode angle values in plastically deformed devices, whereby stress triaxiality and Lode angle are accepted as key indicators for damage initiation in metal forming processes. Attention is paid to components, the material response of whic

In a historical moment inundated by disasters, understanding and conceptualising thephenomenon is a matter of some importance. No framework for doing so has been more productive than that developed by Wisner and his colleagues. But their so-called ‘Progression of Vulnerability’ (pressure and release [PAR] model) framework was conceived before the onset of the climate crisis. And that crisis, as th

Molecular spiders are synthetic biomolecular walkers that use the asymmetry resulting from cleavage of their tracks to bias the direction of their stepping motion. Using Monte Carlo simulations that implement the Gillespie algorithm, we investigate the dependence of the biased motion of molecular spiders, along with binding time and processivity, on tunable experimental parameters, such as number

Among the numerous point vapor sources, microsecond-pulsed spark ablation at atmospheric pressure is a versatile and environmentally friendly method for producing ultrapure inorganic nanoparticles ranging from singlets having sizes smaller than 1 nm to larger agglomerated structures. Due to its fast quenching and extremely high supersaturation, coagulational growth already begins at the atomic sca

Is personnel resistance in deed as dysfunctional as it is assumed to be, in M&A theory? According to Hirschman (1970), voice is more loyal than exit, implying that employees telling their opinion should be understood as a sign of loyalty, rather than a problem. An important aspect of loyalty is its moral basis. Scanning M&A literature, it becomes evident that very little has been written o

BackgroundSocial function is a key aspect of health‐related quality of life after solid organ transplantation (SOT). The focus of this study was to report how solid organ‐transplanted patients change their social function after transplantation.AimTo investigate the main concerns associated with social function after SOT and how solid organ transplant recipients (SOTRs) deal with these concerns.Met

The interest in modelling, analysis and optimisation of supply chain structures has increased in the last decade. Among the reasons are globalisation, a general speed-up of the rate of change in the business environment, the trend towards more outsourcing of activities, and the rapid development in IT. This development has caused more and more people to realise the benefits of supply chain managem

The dynamics of ethanol production/consumption in baker's yeast were studied under feed- rate controlled conditions. The yeast was grown on molasses in an 8-l fed-batch reactor and experiments were done at cell concentrations between 5 and 65 g l−1. Small changes in the feed rate were made around a feed rate corresponding to the critical growth rate, at which the yeast cell metabolism switches bet

Policy intervention schemes for increased deployment of solar photovoltaics (PV) have been launched in several countries, with varying success. In order to ensure an efficient deployment of the technology, thorough knowledge is needed about relevant present actors and institutions, and about how a desirable actor base and institutional setup should look like; mere cost reductions are not enough to

The aim of this study is to understand how employment officers within the sections of establishment at the employment office think of newly arrived immigrant women´s establishment on the Swedish labour market. The study is based on the effecting factors from a micro and macro perspective, I have therefor chosen to look at the enabling and the aggravating factors in relation to individual and socia

En två-kolonn MCSGP process för upprening av Liraglutid genomfördes i laboratorieskala. Den här processen är inte en kommersiell uppreningsprocess, utan att den är ett modellsystem med en realistisk peptidblandning och med en icke-kommersiell harts. Först modellerades processen med en konvektiv dispersiv modell för att beskriva koncentrationen genom kolonnen och den steriska massaktionsmodellen föA twin-column MCSGP process for the purification of Liraglutide was implemented at lab scale. This process is not a commercial separation step, but it is a model system with a realistic peptide mixture and with a non-commercial resin. First, the process was modeled using a convective dispersive model to describe the concentration along the column and the steric mass action model to describe the ad

By combining a legal doctrinal study and an empirical interview study, this thesis examines the implementation of the right to access to justice under article 13 of the Convention on the Rights of Persons with Disabilities for persons who due to post-traumatic stress syndrome have difficulties accounting for their stories in asylum proceedings. The starting point is that persons with PTSD likely w
