A Short Period of Ventilation without Perfusion Seems to Reduce Atelectasis without Harming the Lungs during Ex Vivo Lung Perfusion.

To evaluate the lung function of donors after circulatory deaths (DCDs), ex vivo lung perfusion (EVLP) has been shown to be a valuable method. We present modified EVLP where lung atelectasis is removed, while the lung perfusion is temporarily shut down. Twelve pigs were randomized into two groups: modified EVLP and conventional EVLP. When the lungs had reached 37°C in the EVLP circuit, lung perfus

Design of RF Properties for Vertical Nanowire MOSFETs

The RF performance of vertical nanowire metal-oxide-semiconductor field-effect transistors in realistic layouts has been calculated. The parasitic capacitances have been evaluated using full 3-D finite-element method calculations, combined with self-consistent Schrodinger-Poisson calculations for the intrinsic gate capacitances. It is shown that a performance comparable to planar FETs can be achie

Towards programmatic design research

The notion of design research entails research where design practice forms part of the knowledge production. Based on our characterization of the nature of design, we propose to conceptualize this kind of research as programmatic design research. Two ongoing PhD projects in interaction design are presented as examples of programmatic research processes, highlighting issues to do with the virtues a

Laparoscopic or Open Appendectomy for Pediatric Appendicitis?

Background: This study aimed to compare open appendectomy (OA) and laparoscopic appendectomy (LA) in children by analyzing the differences in outcomes between the two techniques. Materials and Methods: This was a single-institution retrospective study. Data were collected from the medical records of all children

Effect of substrate nanopatterning on the growth and structure of pentacene films

The effect of modulating the structure of thin pentacene (C22H14) films by a nanopatterned inert substrate, known as hexagonal boron nitride nanomesh, is reported. Films of different thickness are grown and characterized by x-ray absorption, core-level photoemission, low-energy electron microscopy, microbeam low-energy electron diffraction, and scanning tunneling microscopy. Initially the pentacen

On the Relation of Mean Reaction Time and Intraindividual Reaction Time Variability

Researchers often statistically control for means when examining individual or age-associated differences in variances, assuming that the relation between the 2 is linear and invariant within and across individuals and age groups. We tested this assumption in the domain of working memory by applying variance-heterogeneity multilevel models to reaction times in the n-back task. Data are from the CO

Calculation of the Molecular and Atomic Properties of Selected Anions in Water.

The polarizability and other properties have been studied for F(-), Cl(-), Br(-), and HCOO(-) in water using a combined quantum chemical statistical mechanics simulation model that explicitly takes into account the Pauli repulsion as well as the electrostatic coupling between the QM system and the classical surroundings. It is shown that the surrounding molecules significantly reduce both the pola

Disability and health after replantation or revascularisation in the upper extremity in a population in southern Sweden - a retrospective long time follow up.

Replantation in the upper extremity is a well-established microsurgical procedure. Many have reported patients' satisfaction and functional measurements.The aim was to investigate the long time consequences as activity limitations in hand/arm, the general health and cold sensitivity after a replantation or revascularization in the upper extremity and to examine if sense of coherence (SOC) can be a

Patterns of functional enzyme activity in fungus farming ambrosia beetles

Introduction: In wood-dwelling fungus-farming weevils, the so-called ambrosia beetles (Curculionidae: Scolytinae and Platypodinae), wood in the excavated tunnels is used as a medium for cultivating fungi by the combined action of digging larvae (which create more space for the fungi to grow) and of adults sowing and pruning the fungus. The beetles are obligately dependent on the fungus that provid

Current knowledge and importance of dGEMRIC techniques in diagnosis of hip joint diseases

Accurate assessment of early hip joint cartilage alterations may help optimize patient selection and follow-up of hip joint preservation surgery. Delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) is sensitive to the glycosaminoglycan content in cartilage that is lost early in the development of osteoarthritis (OA). Hence, the dGEMRIC technique holds promise for the deve

No title

A critical source publication of an unknown letter from the late eighteenth century, of great importance for the later interpretation of the German Moravian spiritual tradition in Sweden.

Improving video segmentation algorithms by detection of and adaption to altered illumination

Changing illumination constitutes a serious challenge for video segmentation algorithms, especially in outdoor scenes under cloudy conditions. Rapid illumination changes, e.g. caused by varying cloud cover, often cause existing segmentation algorithms to erroneously classify large parts of the image as foreground. Here a method that extends existing segmentation algorithms by detecting illuminatio

Priority setting in Swedish health care: Are the politicians ready?

Background: Resource allocation in public health care principally involves politicians, administrators, and physicians. They all have their different roles, agendas and ambitions when it comes to how public health care resources should be spent. Previous studies on attitudes among health-care stakeholders have mainly focused on views and preferences among clinical decision-makers, while less atten

Aspiration as a late complication after accelerated versus conventional radiotherapy in patients with head and neck cancer.

Conclusion Neck dissection after radiotherapy increased the risk of aspiration as a late effect in a sub-sample of patients treated for head and neck cancer in the ARTSCAN study. Patients treated with accelerated fractionation (AF) developed aspiration, with or without coughing, more frequently than patients treated with conventional fractionation (CF). Objectives A long-term follow-up study was c

Vardagens kontraktualisering - Om individuella genomförandeplaner i äldreomsorgen

The aim of the study has been to theorize and investigate the phenomenon of individual plans in eldercare. The article uses a literature-based historical outlook and empirical data in order to study the underlying intentions and practice in the type of individual care plans that are used in contemporary eldercare. The main empirical material consisting of 869 individual care plans was collected an
