At self-similarity the strain history is implicit in and deducible from the strain field at each instance of the loading process. This fact is taken advantage of in a FEM-technique which allows the load to be applied in one single step, only, even when the incremental theory of plastic flow has to be used.

Elastic—plastic anti‐plane strain problems can be solved by using FEM programs developed for plane stress. The technique does not involve any manipulations with the FEM code, but is merely a matter of specialization and of translation of notation. Two analytically solvable cases are chosen for demonstration.

Crude Distillation Unit (CDU) represents significant challenge for retrofitting and energy optimisation as the most energy intensive consumer in a conventional crude oil refinery. Pinch Technology and its based-methodologies are found primary keys for decades to energy savings in refining industries for a range of common economic-based and environmental objectives or applications. Typical benefits

Linnénätet är tänkt att uppmärksamma historiskt intressanta växtlokaler och fokuserar på lokaler som varit kända sedan före 1850. Även om många av dem ingår i Floraväkteriet, så har det sig att flera av dessa inte är skyddade och några har inte ens varit uppmärksammade. Jan Thomas Johansson och Mariette Manktelow har startat detta projekt om historiska växtlokaler i Sverige, och här följer en pres

Background: The influence of gender on bipolar disorder is controversial and it is unclear if inpatient care differs between men and women. Here, we investigate for gender differences in the inpatient length of stay for Swedes admitted for bipolar disorder and explore other factors that could explain any observed association. Methods: Admission data were extracted from the Swedish National Patient

We present a case of combination of a leadless pacemaker (Micra) and a subcutaneous implantable cardioverter-defibrillator (S-ICD). The patient had a total of nine adequate shock treatments of ventricular fibrillation during 18 months of follow-up after the implantation. The shock treatments did not lead to any alteration in the Micra. All three sensing vectors of the S-ICD worked well. After 18 m

Aims: In this article we explore the moderators of effectiveness of WISEteens (Web-based brief Intervention for SubstancE using teens), a fully automated web-based brief motivational intervention targeting risky substance use among adolescents. Based on previous studies, we examined the differential effects on drinking of sex, readiness to change, self-efficacy, alcohol risk status, and parental m

This paper presents a novel method to calculate the T-matrix for two non-spherical obstacles positioned close to each other, where the individual circumscribed spheres intersect. This is achieved by translating the obstacles coordinate systems, using translation matrices for spherical vector waves. The new circumscribing spheres enables the obstacles to be positioned close to each other. A new tot

Within a period of ten years a large number of schools need to be built in Sweden and these new schools need to be nearly zero energy buildings. School classrooms are required to provide healthy learning environments to help children perceive and process information. This means that classrooms must provide adequate levels of indoor air quality and thermal comfort. This article investigates CO2 con

Background In many countries, smoking is considered as the most important preventable risk factor for a complicated pregnancy and delivery. However in Denmark, there is no clear picture of pregnant women. The aim was therefore to examine the prevalence, characteristics and registration of maternal smoking and quitting during pregnancy as well as estimate the potential for improvement.Methods This
