Förekomst av farliga ämnen i byggnader medför betydande osäkerheter i projektplanering och budgetuppskattning och innebär hälso och säkerhetsrisk för de boende och för arbetstagare som är involverade i renoverings- och rivningsaktiviteter. Det är praxis inom svenska byggprojekt att avsätta ungefär 15% av budgeten för att hantera oväntade risker av farliga ämnen och oförutsedda händelser. De faktis

Background and purpose: Advances in characterizing cancer biology and the growing availability of novel targeted agents and immune therapeutics have significantly changed the prognosis of many patients with metastatic disease. Palliative radiotherapy needs to adapt to these developments. In this study, we summarize the available evidence for stereotactic body radiotherapy (SBRT) in the treatment o

The MAX IV 3 GeV linac delivers electron beams to two synchrotron rings and to a dedicated undulator system for X-ray beam delivery in the Short Pulse Facility (SPF). In addition, there are plans to use the linac as an injector for a future Soft X-ray Laser (SXL). For both SPF and SXL operations, longitudinal beam characterisation with a high temporal resolution is essential. For this purpose, a t

We consider a system of equations that model the temperature, electric potential and deformation of a thermoviscoelastic body. A typical application is a thermistor; an electrical component that can be used e.g. as a surge protector, temperature sensor or for very precise positioning. We introduce a full discretization based on standard finite elements in space and a semi-implicit Euler-type metho

Clinical research usually involves time-to-event survival analysis, in which the presence of a competing event is prevalent. It is acceptable to use the conventional Cox proportional hazard regression to model cause-specific hazard. However, this cause-specific hazard cannot directly translate to the cumulative incidence function, and the latter is usually clinically relevant. The subdistribution

Mobile Stroke Units (MSUs) are specialized ambulances that can diagnose and treat stroke patients; hence, reducing the time to treatment for stroke patients. Optimal placement of MSUs in a geographic region enables to maximize access to treatment for stroke patients. We contribute a mathematical model to optimally place MSUs in a geographic region. The objective function of the model takes the tra

In this paper we inquire into the relationships between the Greek myth of Phaeton and Volkswagen's project to produce a luxury car (named Phaeton). Volkswagen apparently felt that the lack of a luxury car opened the possibility to question their 'son-of-God status', just like Phaeton in the Greek story. This inquiry is contextualized in the emergence of a more and more direct art-management relati

The evolution of reading frame maintenance must have been an early event, and presumably preceded the emergence of the three domains Archaea, Bacteria and Eukarya. Features evolved early in reading frame maintenance may still exist in present-day organisms. We show that one such feature may be the modified nucleoside 1-methylguanosine (m(1)G37), which prevents frameshifting and is present adjacent

In this paper, we present a study of Swedish inhabitants' preferences for distribution in three dimensions in the context of transport investments. Using choice experiments, we study the respondents' preferences for the distribution of benefits in the geographical, gender, and income dimension in relation to aggregate benefits. We find that they have quite strong preferences for equality in all di

This paper develops a conceptual framework for understanding how organizations create an accepted purpose for organizational change initiatives related to business processes. The framework is based on a longitudinal study related to an Action Research project and the ‘higher level learning’ from using a performance measurement system for change initiatives. Over more than four years, we followed a

AimOur aim is to provide a-priori information on air-quality implications of potential future energy carriers in transportation relevant for sustainability, life cycle and health-impact assessments.MethodologyInformation on air- and climate-pollutant formation from energy carriers is collected in detailed laboratory assessments on heavy-duty combustion engines as well as on non-tailpipe emissions.

We study experimentally work fluctuations in a Szilard engine that extracts work from information encoded as the occupancy of an electron level in a semiconductor quantum dot. We show that as the average work extracted per bit of information increases toward the Landauer limit Formula Presented, the work fluctuations decrease in accordance with the work fluctuation-dissipation relation. We compare

Research on the efficacy of hypnosis applications continues to grow, but there remain major gaps between the science and clinical practice. One challenge has been a lack of consensus on which applications of hypnosis are efficacious based on research evidence. In 2018, 6 major hypnosis organizations collaborated to form the Task Force for Establishing Efficacy Standards for Clinical Hypnosis. This

The paper suggests a method for compensating the impact of friction for the control nonlinear systems, where the original controller (derived without taking into account friction) results from the passivity relation. The illustrative example is given.

We discuss the Layzer quenched ground state configuration of [Kr]4d104f13 along the Praseodymium (Pr) isoelectronic sequence between 80≤Z≤100. The 2F fine structure energy is examined from the point of view of the various contirbutions: correlation, frequency-independent and dependent Breit interaction and the two QED terms, self energy and vacuum polarisation. We find the fine structure energy to
