We report on magnetoresistance (MR) studies on Co/AlOX/Au and Co/AlOX/Ni/Au magnetic tunnel junctions. In spite of the fact that the difference between the two samples is merely a 3 nm thick Ni layer, there is a sharp contrast in MR behavior indicating that the electronic structure at the interface between the ferromagnetic electrodes and the insulating barrier dominates the MR signal. The former
Aims and objectives To explore healthy older patients' perceptions of their own capacity to regain pre-fracture function in the acute phase following hip fracture surgery. Background The incidence of hip fractures is expected to increase. In Sweden, of the patients who sustain a hip fracture, 40 per cent are healthy and lived independently pre fracture. However, a hip fracture often results in dec
Performance of cutting tool in hard turning is significantly influenced by its microgeometry, such as edge radius. This study presents an experimental exploration to understand the effect of cutting edge radius on machining performance in terms of surface roughness and tool wear. The cutting tools (CBN) with three groups of nominal edge radius, 20, 30, and 40 μm, were used in the study. The cuttin
Eutrophication is one of the most serious global threats to coastal areas. One effect of eutrophication is seasonal macroalgal blooms. As a consequence, large amounts of beach-cast algae are today reported from coastal areas worldwide. In this study, we analyze nonmarket benefits by capturing local residents' Willingness To Pay (WTP) for an environmental program to regularly remove and utilize bea
Non-traditional examples can be very inspiring for students. This paper applies classical mechanics to different ways of skating in ice hockey. Skating blades glide easily along the ice in the direction of the blade. Horizontal forces on the skates are thus essentially perpendicular to the blade. Speed skaters glide long distances on each skate before pushing off for the next stride. A hockey play
Seaweed cultivation is a large industry worldwide, but production in Europe is small compared to production in Asian countries. In the EU, the motivations for seaweed farming may be seen from two perspectives; one being economic growth through biomass production and the other being the provisioning of ecosystem services such as mitigating eutrophication. In this paper, we assess the economic poten
Diamond-Blackfan anemia (DBA) is a rare congenital disease where the patients suffer from macrocytic anemia due to reduced numbers of erythroid precursors in the bone marrow. Most patients carry mutations in ribosomal proteins, such as ribosomal protein S19 (RPS19), which causes deficient ribosome biogenesis and affects protein translation. Ribosomal protein mutations also cause increased apoptosi
The ISO22400 standard defines key performance indicators for manufacturing operation management. Its visionary goal is to be applicable to all industry types, regardless the production methodology and the process configuration. Pursuing this objective, a challenging trade-off between generality and specificity in the definitions must be found. In the cited standard, the former approach has been pr
Investigating the chemical homogeneity of stars born from the same molecular cloud at virtually the same time is very important for our understanding of the chemical enrichment of the interstellar medium and with it the chemical evolution of the Galaxy. One major cause of inhomogeneities in the abundances of open clusters is stellar evolution of the cluster members. In this work, we investigate va
OBJECTIVE: The objective is to systematically review the literature on economic evaluations of screening interventions for early diagnosis of dementia disorders. METHODS: A systematic search of published economic evaluation studies in English was conducted using specified key words in relevant databased and websites. Data extracted included methods and empirical evidence (costs, effects, increment
Background: High-sensitivity assays for cardiac troponin T (hs-cTnT) are sometimes used to rapidly rule out acute myocardial infarction (AMI).Purpose: To estimate the ability of a single hs-cTnT concentration below the limit of detection (<0.005 µg/L) and a nonischemic electrocardiogram (ECG) to rule out AMI in adults presenting to the emergency department (ED) with chest pain.Data Sources: EMBASE
Aim and objectives: To explore nurses’ articulations of support and communication regarding sexual health with patients.Background: Sexual health is adversely effected by cancer and various oncological treatments. Patients’ often have the experience that health-care professionals do not talk about sexual health.Method: Semi-structured interviews were conducted with seven nurses in Southern Sweden.Aim and objectives: To explore nurses' articulations of support and communication regarding sexual health with patients.

The aim of this special issue is to invite scholars in public administration to address issues of power in relation to evaluation practices in the public sector. Power is one of those big, difficult, and inherently nebulous concepts that both scholars and practitioners appear to consciously or unconsciously avoid. Our ambition in this introduction is not to present a comprehensive conceptual revieThe aim of this special issue is to invite scholars in public administration to address issues of power in relation to evaluation practices in the public sector.

In what ways can various perspectives, aims, circumstances, and directives influence music students and music teachers in different educational contexts such as primary school, Schools of music and performing arts (SMPA), folk high school, and upper secondary school, viewed from a Nordic perspective?A common characteristic for all these types of schools is that they can be part of an educational a
Starch nanoparticles (SNPs) have been synthesized by nanoprecipitation method using starches from different botanical sources in native form and modified with octenyl succinic anhydride (OSA). SNPs were characterized in terms of size, morphology, charge, XRPD, FTIR and thermal properties. Spherical particles were obtained with sizes ranging from 54 to 108 nm and zeta potential values from −2 to −2
Introduction: Traumatic brain injury to thalamo-cortical pathways is associated with posttraumatic morbidity. Diffuse mechanical forces to white matter tracts and deep grey matter regions induce an inflammatory response and vascular damage resulting in progressive neurodegeneration. Pro-inflammatory cytokines, including interleukin-1β (IL-1β), may contribute to the link between inflammation and th
Betrayal often hits the very foundations of socials bonds: the loyalty of the “We” that we have assumed and taken for granted is broken. This chapter will begin with a discussion of the meaning of betrayal where it is argued that betrayal is a breach of trust, when information is shared, or actions initiated beyond an agreed upon boundary of relations.The image of betrayal is associated with moral
Neurological and cardiac injuries are significant contributors to morbidity and mortality following pediatric in-hospital cardiac arrest (IHCA). Preservation of mitochondrial function may be critical for reducing these injuries. Dimethyl fumarate (DMF) has shown potential to enhance mitochondrial content and reduce oxidative damage. To investigate the efficacy of DMF in mitigating mitochondrial in
The effectiveness of both preoperative autologous donation (PAD) and intraoperative autotransfusion (IAT) with an autotransfusion device has recently been questioned. Preoperative apheresis, with separation of concentrated platelet rich-plasma (c-PRP) and erythrocyte concentrate (ERC), represents an aggressive use of the autotransfusion device. Can such a procedure replace PAD in total hip replace
