Background: Available interventions for preventing fragility hip fractures show limited efficacy. Injection of a biomaterial as bone substitute could increase the fracture strength of the hip. This study aimed to show the feasibility of injecting a calcium sulfate/hydroxyapatite based biomaterial in the femoral neck and to calculate the consequent change in strength using the finite element method

What did Martin Luther King, Jr, mean to his Scandinavian admirers, especially around the time of his Nobel Peace Prize.

We have studied strain wave generation in graphite induced by an intense ultrashort laser pulse. The study was performed in the intensity regime above the ablation threshold of graphite. The aim was to maximize the strain and, thus, also the internal pressure (stress). Laser pulses with a 1 ps temporal duration melt the surface of graphite resulting in a molten material which initially exists at t

BACKGROUND AND PURPOSE: Increased CSF stroke volume through the cerebral aqueduct has been proposed as a possible indicator of positive surgical outcome in patients with idiopathic normal pressure hydrocephalus; however, consensus is lacking. In this prospective study, we aimed to compare CSF flow parameters in patients with idiopathic normal pressure hydrocephalus with those in healthy controls a

We monitored foraging insectivorous bats along walked transects in forest and farmland at Arabuko-Sokoke Forest in coastal Kenya, using a heterodyne bat detector. The main purpose was to test whether aerial-hawking insectivorous bats that feed in open places (in this case mostly Scotophilus and Scotoecus spp.) show lunar phobia, i.e. restricting their activity on moonlit nights. Such behavior woul

This article introduces the special edition entitled ‘Critical reflections on contemporary higher education and developments of and in internationalization’. The articles presented here have resulted from the growing interest in internationalisation among members of the European Educational Research Association Network 22, Research in Higher Education. The authors responded to a special call for p

Background: Creativity can be defined as the creation of something that is novel, useful, and valuable for society (i.e., high-level creativity) and/or everyday life. In this context, people have implicit theories of creativity as being either non-malleable (i.e., a fixed creative mindset) or malleable (i.e., a growth creative mindset). Our aim was twofold: (1) to test an improved creative mindset

First results on K / π, p / π and K/p fluctuations are obtained with the ALICE detector at the CERN LHC as a function of centrality in Pb--Pb collisions at sNN=2.76TeV. The observable ν dyn , which is defined in terms of the moments of particle multiplicity distributions, is used to quantify the magnitude of dynamical fluctuations of relative particle yields and also provides insight into the corr

Various emerging technologies, such as autonomous vehicles and fully autonomous flying, require precision positioning. This work presents a localization and tracking method based on joint direction of arrival (DOA), time delay, and range estimation using the SAGE algorithm. The proposed method does not rely on external sources of information such as global navigation satellite systems (GNSS). The

A multiline Thru-Reflect-Line (mTRL) calibration and parasitic pad removal kit is presented, intended for mm-wave III-V nanowire MOSFET characterization. Multiline TRL is implemented in a low-temperature BEOL process with substrate decoupled microstrip transmission lines. The transmission line characteristic impedance needed for accurate mTRL calibration is modelled. Simulated transmission line pa

This article assesses how Swedish parliamentary democracy works today, almost one hundred years into its history. Our main research question is whether the transformation of the Swedish party system since the 1980s—and especially since 2010, when the populist-radical-right Sweden Democrats entered parliament—has altered the way parliamentary democracy works. We provide new evidence on Sweden’s cha

There is a great unmet clinical need to identify patients with thin primary cutaneous melanomas (T1, Breslow thickness ≤ 1 mm) who have a high risk for tumour recurrence and death from melanoma. Kin of IRRE-like protein 1 (KIRREL/NEPH1) is expressed in podocytes and involved in glomerular filtration. Screening in the Human Protein Atlas portal revealed a particularly high expression of KIRREL in m

This article presents new evidence on the efforts of states to collect and process information about themselves, their territories, and their populations. We compile data on five institutions and policies: the regular implementation of a reliable census, the regular release of statistical yearbooks, the introduction of civil and population registers, and the establishment of a government agency ta

Objective: The de-institutionalizing process came to an end before the millennium shift by closing mental hospitals. After that some of the most ill patients are cared for in sheltered housing (SH). There is no in-house psychiatric competence and the staff on the floor usually lacks such knowledge and training. Observation instruments may improve this by making it possible to assess and monitor pa

Neutrophil extracellular traps (NETs) are involved in acute pancreatitis (AP) but mechanisms controlling NET expulsion in AP are incompletely understood. Herein, we examined the role of c-Abelson (c-Abl) kinase in NET formation and tissue damage in severe AP. AP was induced by taurocholate infusion into pancreatic duct or intraperitoneal administration of l-arginine in mice. Pancreatic, lung, and

Alpha-1-antitrypsin deficiency (AATD) is a hereditary disorder. AATD is a known risk factor for the development of emphysema and liver disease. A cohort of severe (PiZZ) and moderate (PiSZ) AAT-deficient newborn infants was identified by the Swedish national neonatal AAT screening in 1972-1974 and has been followed up since birth. Our aim was to study survival in this cohort up to 43-45 years of a
