In this study, a coupled transient thermomechanical finite element model is developed to examine the laser powder bed fusion (L-PBF) process of the Inconel 718 (IN718) and Oxide Dispersion Strengthened (ODS) superalloys (ODS-IN718). The linear isotropic elastic perfectly plastic constitutive model is implemented for the mechanical part whereas all the thermophysical properties are defined as fully

In this study, a bond-based fully coupled thermomechanical peridynamic framework is implemented to study the fracture toughening of stop-holes in brittle materials subjected to thermomechanical loads. The developed modelling approach aims to provide comprehensive guidance about thermal effects on the fracture toughening mechanism of inclusions under realistic engineering conditions. First, the mod

One of the important challenges in city gate gas pressure reduction stations is the heating of the natural gas prior to pressure reduction. Regarding the low efficiency of the common water bath heaters in these stations another type of double tube-pass shell and tube heat exchanger, equipped with flower baffles, has been proposed for heating the natural gas. Additionally, Al2O3 nanofluid has been

The purpose of this dissertation is to explore the heritagisation of Swedish sports, which is examined through studies of five Swedish sports museums of today. Additionally, the disseration explores the heritagisation of Swedish sports in a wider historical perspective, mainly focusing on the years between 1900 and 2000.There are plenty of sports museums in Sweden today, most of them run by amateu

Background: Young adults experience stressors in their transition to adulthood and are at increased risk of mental ill-health. This risk is compounded by young adults’ low levels of mental health literacy and limited competencies in implementing strategies promoting mental health and well-being in their daily lives. Previous research suggests that digital mental health apps may be particularly eff

BACKGROUND: Prone positioning is part of the management of acute respiratory distress syndrome (ARDS) and has been demonstrated to successfully improve the ventilation-perfusion match and reduce mortality in patients with severe respiratory failure. However, the effect of pronation on other organs than the lungs has not been widely studied. This study aimed to compare abdominal edema, perfusion an

This paper contributes to the empirical question of the labour organization and gender division of labour in a semi-landless rural group during the second half of the nineteenth century, a period charac-terized by developing agrarian capitalism. Thereby, we also add to the broader question of the role of gender division of labour in economic transformation. Through a triangulation of sources – cro

CONTEXT: As part of a broader institutional initiative, the serious illness care program was implemented in a multi-site academic primary care practice. After 2 years, a minority was observed to be documenting serious illness conversations routinely.OBJECTIVES: We aimed to learn about the motivations and actions of clinicians who routinely conducted and documented serious illness conversations.MET

ABSTRACTThe aim of this working paper is to expand the range of pedagogical tools for teaching statistics to social work students, by introducing an innovative tool that is based on the factorial survey and intended for practicing statistical analysis. The factorial survey, which was pioneered by the American sociologist Peter Rossi around 45 years ago, involves the use of experimentally constructThe aim of this working paper is to expand the range of pedagogical tools for teaching statistics to social work students, by introducing an innovative tool that is based on the factorial survey and intended for practicing statistical analysis.

Palestinians represent one of the largest refugee populations in the world, and are reserved a special legal status under Article 1D of the Refugee Convention. A number of urgent novel questions are now also arising from the current genocide and mass displacement in Gaza, yet the refugee law studies community on the whole remains silent. This article examines academic silence and Israeli pinkwashi

Isotopic differences in the distribution of nuclear charge and magnetization give rise to "hyperfine structure anomalies" which were observed already in the 1950s. More recently, the distribution of nuclear magnetization has been found to complicate the interpretation of the measured hyperfine splittings in highly charged hydrogen-like ions. In this paper, results of numerical calculations for a f

By the use of relativistic many-body theory, the hyperfine structure of the 7p state of Fr211 was calculated. By including polarization effects in all orders, good agreement for the magnetic dipole constant was obtained. In the same way, a new value of the electric quadrupole moment is obtained: Q=-240 mb for Fr211(P322).

Radiative lifetimes have been determined for the 62P12/0 and 62P32/0 levels in Yb II using the method of laser-induced fluorescence from sputtered metal vapour. The results, 8.0(2)ns (62P12/0) and 6.3(3)ns (62P32/0), are compared with lifetimes obtained from ab initio manybody perturbation calculations.

There are many laws of physics involved in the design and operation of roller coasters, carousels, and other amusement rides. Physics for the Whole Body in Playgrounds and Amusement Parks teaches these concepts in an exciting and approachable way by linking them with students’ personal experiences of rides in amusement parks.This unique book features:Immersive elements to learn scientific principl

Quantum mechanics has been enormously successful. The equations and rules enable accurate calculations and predictions of energies and other properties of atoms, molecules, and materials. Quantum-physics-based technology is an integrated part of our daily lives. Still, the understanding and interpretation of quantum physics offer many challenges, with the counterintuitive consequences of the rules
