By using dislocation simulation approach, the basic equation was formulated. A novel expansion method was proposed for solving the problem. The complete solution to the problem, including the explicit formulae for the T stresses ahead of the crack tip and the stress intensity factors were presented. The stress field characteristics were analysed in detail. It is found that the normal stresses ahea
Wrought Alloy 600 and Alloy 182 weld metal were tested for stress corrosion crack initiation in a BWR test loop. For the tests a modified bolt loaded compact tension specimen was developed, in which a U-notch replaced the conventional crack notch. The stress state close to notches of various radii was analyzed. Specimens with various notch radii were loaded to the same displacement at the bolt. A
A potential drop method, as used for estimations of crack lengths during three‐point‐beind experiments, is studied. The mechanical state is calculated using a finite element method. The deformed body obtained is used for a subsequent calculation of the electrostatic state. Calculations are performed for both two‐ and three‐dimensional models. The material is assumed to be elastic, linearly hardeni
BackgroundAt least 50% of all ambulance assignments are deemed nonurgent, while 47–96% are initiated by someone other than the patient. Previous research has highlighted the importance of being taken seriously. However, additional knowledge of how significant others experience the situation when a patient is assessed as nonurgent is needed.ObjectiveThe aim of this study was to explore the person‐c
BACKGROUND: The indication, composition and timing of administration of non-resuscitation fluid in septic shock have so far received little attention and accordingly the potential to reduce this source of fluid is unknown. The objective of the study was to quantify and characterize non-resuscitation fluid administered to patients with septic shock.METHODS: This prospective observational study was
Study of British film Denial (2016), which is about the Irving-Lipstadt trial in London in 2000, where Holocaust denier David Irving sued American Judaist Deborah Lipstadt for libel, and lost.
In this essay it is argued that Bergman deviated from his highly critical depictions of bourgeois life in the films of the 1960s and 1970s, from Persona (1966) to the television series Scenes from a Marriage (1973), in Fanny and Alexander (1982), his final contribution to films made for the cinema. Bergman himself came from an upper-class bourgeois background, and by his own account he did not tak
In line with the need to better utilize agricultural resources, and valorize underutilized fractions, we have developed protocols to increase the use of wheat bran, to improve utilization of this resource to additional products. Here, we report sequential processing for extraction of starch, lipids, and proteins from wheat brans with two different particle sizes leaving a rest-material enriched in
Erfarenheterna från de amerikanska delstater som legaliserat cannabis visar att brottsligheten i princip inte påverkats alls. Forskningen visar också att insatser mot narkotikamarknaderna inte säkert skulle minska våldet. För att bekämpa gängvåldet bör insatserna i stället riktas mot våldet i sig, skriver forskarna Manne Gerell, Björn Johnson och Petter Karlsson.
”Kunskap ska spela roll och värderas högre än magkänsla och ingrodda idéer” skriver Joar Forsell, ordförande i Liberala ungdomsförbundet, i en debattartikel om svensk narkotikapolitik (DN Debatt 27/3). Tyvärr utgör artikeln ett gott exempel på just det problem Forsell säger sig vilja komma tillrätta med, den är nämligen späckad med faktafel, skriver Björn Johnson och Petter Karlsson.
