Purpose: This paper aims to discuss additive manufacturing (AM) in the context of applications for musical instruments. It examines the main AM technologies used in musical instruments, goes through a history of musical applications of AM and raises the questions about the application of AM to create completely new wind instruments that would be impossible to produce with conventional manufacturin
Introduction: Traditional validation of umbilical cord blood samples with positive veno-arterial ΔpH and arterio-venous ΔpCO2 values confirms the source of samples, whereas negative Δvalues represent mix-up of samples. To investigate whether this is true, the distributions of V-A ΔpO2 and A-V Δlactate were also explored and related to clinical characteristics. In addition, different cord blood sam
BACKGROUND: With increased access to antiretroviral treatment (ART) in sub-Saharan Africa emergence of HIV-1 pretreatment drug resistance constitutes a serious risk. This may lead to rapid virological failure in subjects initiating ART, and mother-to-child transmission despite prophylaxis.METHODS: Treatment-naïve pregnant women from four antenatal care clinics in Bissau, Guinea-Bissau, were enroll
Objective: Inflammation is associated with major depressive disorder (MDD) and suicidal behavior. According to the ‘leaky gut hypothesis’, increased intestinal permeability may contribute to this relationship via bacterial translocation across enterocytes. We measured plasma levels of gut permeability markers, in patients with a recent suicide attempt (rSA), MDD subjects with no history of a suici
Aim/Purpose The goal of this paper is to examine digital applications used in Swedish schools and whether they fulfill their potential as support for learners. This is done by examining the kinds of feedback they provide and discussing if this feedback supports learning or not. Background The paper targets one aspect regarding which educational apps can be of high value for learners and teachers,
Atmospheric aerosols are a highly complex and dynamic mixture of solid particles, liquid deplots and gases. They travel across the continents and affect global climate and human health in various ways, often negatively. One important aspect of research in atmospheric aerosols is the investigation of emissions to the atmosphere from various sources. Emission markers are compounds unique to their soAtmospheric aerosols are a highly complex and dynamic mixture of solid particles, liquid deplots and gases.

Prostate cancer radiotherapy workflows, solely based on magnetic resonance imaging (MRI), are now in clinical use. In these workflows, intraprostatic gold fiducial markers (GFM) show similar signal behavior as calcifications and bleeding in T2-weighted MRI-images. Accurate GFM identification in MRI-only radiotherapy workflows is therefore a major challenge. C-arm X-ray images (CkV-images), acquire
This article reports on a Small-N study of Centre of Excellence (CoE) schemes that cover a wide variety of such schemes. The purpose is to map the ways in which strategic aims of CoE schemes relate to impacts and capacity development, and the role played by institutional arrangements such as selection, funding, evaluation, and governance in translating strategy into capacity development and other
Background: It remains unclear whether total or subtotal parathyroidectomy for secondary hyperparathyroidism yields the best outcomes. We investigated mortality, cardiovascular events, hip fracture, and recurrent parathyroidectomy after total versus subtotal parathyroidectomy in patients on renal replacement therapy. Methods: Using the Swedish Renal Registry, the surgical registry for thyroid and
Green packaging development (GPD) involves the process of developing packaging with minimized environmental impact. Over the last decade, the GPD perspective has evolved from a traditionally packaging material-focused one to a holistic one. A holistic perspective on GPD means that the different environmental requirements on packaging have to be combined so that the overall environmental impact of
OBJECTIVES: The aim of our study was to describe and compare models of intensive care follow-up in Denmark, Norway and Sweden to help inform clinicians regarding the establishment and continuation of ICU aftercare programmes.METHODS: Our study had a multi-centre comparative qualitative design with triangulation of sources, methods and investigators. We combined prospective data from semi-structure
This study examines the network of supply and use of significant innovations across industries in Sweden, 1970-2013. It is found that 30% of innovation patterns can be predicted by network stimulus from backward and forward linkages. The network is hierarchical, characterized by hubs that connect diverse industries in closely knitted communities. To explain the network structure, a preferential we
Bildtagning med magnetresonans (mangetic resonance imaging eller MRI) är en fascinerande teknik som använder magnetfält och radiovågor för att skapa detaljerade bilder av kroppens innanmäte. Tvärt om mot vad många tror så finns det ingen ”magnetröntgen” i MR-kameran, och därmed ingen skadlig joniserande strålning. Detta gör det möjligt att utföra upprepade undersökningar på friska och sjuka försök
The finance literature offers ambiguous predictions about the impact of lending relationships on the share retained by lead arrangers in syndicated loans. While some literature indicates that lending relationships can help to alleviate post contractual agency conflicts, others imply that relationship lead arrangers may use their information advantage to exploit syndicate participants. Using syndic
This paper explores whether refinancing risk is an important determinant of maturity decisions by investigating how firms with refinancing risk choose the maturity of new loans they obtain during the 2007-2009 financial crisis. The firms' refinancing risk is measured by the maturing portion of outstanding long-term debt. The result shows that firms with a high refinancing risk choose longer maturi
This paper studies the persistent effects of short-term peer exposure in a college setting. I exploit the random assignment of undergraduates to peer groups during a mandatory orientation week and follow the students until graduation. High levels of peer ability in a group harm the students’ test scores and lead to increases in the probability of early dropout; this result is driven by the adverse
