Many buildings, both new and old, suffer from moisture-related problems, with negative consequences on health, costs for rebuilding and lost confidence in the building industry. These problems could have been avoided if moisture issues had been focused on and dealt with throughout the building process. A method for including moisture safety in the building process has therefore been developed. The

Excitation of a core electron and the subsequent emission of an Auger electron is described in a simplified model, where the core electrons couple only to the plasma oscillations of the conduction electrons and not to individual electron-hole excitations. Results are evaluated to lowest nontrivial order, namely when only terms linear in the interaction with the exciting probe and linear in the Aug

Background: Process evaluations are an important component in the interpretation and understanding of outcomes in trials. The Online Remote Behavioural Intervention for Tics (ORBIT) study is a randomized controlled trial evaluating the effectiveness of an Internet-delivered behavioural intervention (called BIP TIC) compared to an Internet-delivered education programme aimed at children and young p

Bakgrund: Till följd av att den globala konkurrensen tilltar, ökar komplexiteten, flexibiliteten och produktvariationen inom produktion. Detta leder till att förbättringsprojekt blir allt svårare att genomföra. Händelsestyrd simulering har i litteraturen blivit identifierat som ett verktyg med förmågan att lösa dessa utmaningar, men till följd av att komplexiteten i en produktion ökar, växer ocksåBackground: Following a growing global competition, complexity, flexibility and product variability of manufacturing systems are increasing. This has led to improvement projects becoming more difficult to carry out. Discrete event simulation (DES) has in literature been identified as having the capability to solve these challenges, but as complexity of a manufacturing system increases so does also

Recent calls for a revision of standard evolutionary theory (SET) are based partly on arguments about the reciprocal causation. Reciprocal causation means that cause–effect relationships are bi-directional, as a cause could later become an effect and vice versa. Such dynamic cause-effect relationships raise questions about the distinction between proximate and ultimate causes, as originally formul

The problem of continuous-time process parameter identification is considered. Filtered input-output process signals are used to create a linear differential equation governed by the same continuous-time process parameters. The estimation scheme is implemented by sampling the filtered signals and using a recursive least squares algorithm (RLS). The choice of filter leads to different parameter con

Construction projects affect the community in both positive and negative ways. Positive effects are, for instance, better communications, better housing, and a higher standard of living. However, construction projects inevitably bring with them deterioration and changes on the local plane, at the site of the construction project. Thus, in construction projects, many different and sometimes controv

Evaluating the effect of measurement errors on either adaptive or simultaneous control charts has been a topic of interest for the researchers in the recent years. Nevertheless, the effect of measurement errors on both adaptive and simultaneous monitoring control charts has not been considered yet. In this paper, through extensive numerical studies, we evaluate the effect of measurement errors on

Cyclic nucleotide phosphodiesterases (PDEs) are important regulators of signal transduction processes mediated by cAMP and cGMP. One PDE family member, PDE3B, plays an important role in the regulation of a variety of metabolic processes such as lipolysis and insulin secretion. In this study, the cellular localization and the role of PDE3B in the regulation of triglyceride, cholesterol and glucose

Operation med konstgjorda ledproteser i höft och knä ger generellt mycket lyckade resultat. Fortfarande förekommer dock lossning och slitage av komponenterna som ett problem, och alla patienter blir inte fullt nöjda. I ett flertal forskningsprojekt studerar vi faktorer av betydelse för fixation och funktion av proteskomponenterna. Vi utvärderar hur man optimerar de biomekaniska ledförhållandena viTotal joint replacements, both in the hip and knee, are generally very successful operations. Still, however, component loosening as well as wear remains a problem, and all patients are not fully satisfied with their new joint. In a number of ongoing investigations, we are studying different factors involved in the fixation and function of the prosthesis components. We are exploring how to optimiz

The effective management of end-users and their requirements in construction projects can bring a number of benefits, for example more satisfied and less critical end-users in terms of both the product and project. Building occupants are however continually changing and with that their needs. It is thereby a challenge to understand what brings value for both known and unknown end-users. More over

After several years of disussions, tests, investigations and additional tests, the suppliers and retailers within the Swedish business sector for food and commodities formed a jointly owned, non-profit company in 1997, which subsequently started in physical operations in 2000. This company, Svenska Retursystem AB (www.retursystem.se), is now responsible for introducing returnable transport packagi
