Head midline position for preventing the occurrence or extension of germinal matrix-intraventricular hemorrhage in preterm infants

Background: Preterm birth is known to constitute the major risk factor for development of germinal matrix-intraventricular hemorrhage (GM-IVH). Head position may affect cerebral hemodynamics and thus may be involved indirectly in development of GM-IVH. Turning the head toward one side may functionally occlude jugular venous drainage on the ipsilateral side while increasing intracranial pressure an

Risk factors for developing hypoxic respiratory failure in COPD

Background: Hypoxemia is associated with worse outcomes in COPD. The aim of the study was to investigate the prevalence, incidence, and risk factors of hypoxic respiratory failure (HRF) in COPD. Patients and methods: This was a longitudinal analysis of data from the Swedish National Register of COPD. HRF was defined as resting saturation ≤88% or long-term oxygen therapy. Risk factors for developin

On the Design of Channel Shortening Demodulators for Iterative Receivers in Linear Vector Channels

We consider designing demodulators for linear vector channels that use reduced-size trellis descriptions for the received signal. We assume an iterative receiver and use interference cancellation (IC) with soft-information provided by an outer decoder to mitigate the signal part that is not covered by a reduced-size trellis description. In order to reach a trellis description, a linear filter is a

Mixing work and private activities in the digital working life. A diary study.

Laptops and smartphones are now challenging the traditional boarders of work and have contributed to new ways of combining work and other parts of life. Both time and room dimensions have been resolved or taken new forms through the new information and communication technology. Questions like when and where you are supposed to, or can or want to work are likewise important to companies and employeLaptops and smartphones are now challenging the traditional boarders of work and have contributed to new ways of combining work and other parts of life.

Effects of forest management on greenhouse gas fluxes in a boreal forest

Skogar täcker ca 31% av jordens landyta och lagrar stora mängder kol i biomassa och i marken. I klimatavtalet från Paris 2015 lyfts skogars roll som sänkor och reservoarer av kol fram och undertecknande länder uppmanas att implementera strategier för hållbart skogsbruk som ytterligare förstärker skogars roll som sänkor av växthusgaser. Ett aktivt skogsbruk påverkar klimat och miljö på många olika Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies. Managing forests for climate mitigation purposes is, however, complex since management

The Use of Aquatic Resources by Early Mesolithic Foragers in Southern Scandinavia

A long tradition in research on prehistoric southern Scandinavia recognizes full use of aquatic resources in the Late Mesolithic Ertebølle Culture (5500–4000 cal BC): coastal sites are frequently found containing well-preserved fish bones, and isotope values from human collagen indicate a high dietary intake of marine resources. However, recent finds and new methodologies suggest that the view of

Thermal stress analysis of sulfur deactivated solid oxide fuel cells

Hydrogen sulfide in fuels can deactivate catalyst for solid oxide fuel cells, which has become one of the most critical challenges to stability. The reactions between sulfur and catalyst will cause phase changes, leading to increase in cell polarization and mechanical mismatch. A three-dimensional computational fluid dynamics (CFD) approach based on the finite element method (FEM) is thus used to

Graphite/p-SiC Schottky Diodes Prepared by Transferring Drawn Graphite Films onto SiC

Graphite/p-SiC Schottky diodes are fabricated using the recently suggested technique of transferring drawn graphite films onto p-SiC single-crystal substrates. The current–voltage and capacitance–voltage characteristics are measured at different temperatures and at different frequencies of a small-signal AC signal, respectively. The temperature dependences of the potential-barrier height and of th

Social Assistance and Mental Health: Evidence from Longitudinal Data on Pharmaceutical Consumption

This paper examines the short-term effect between take-up of Social Assistance Benefit (SAB) and mental health. Using a panel dataset including rich yearly register data on e.g. income, income sources, unemployment and types of pharmaceutical consumption for over 140,000 Swedes 2006-2012, we quantify the importance of the psychosocial dimensions (e.g. shame and guilt) of the socioeconomic status –

Stock Market Returns and Consumption

This paper employs Swedish data on households' stock holdings to investigate how consumption responds to changes in stock market returns. We instrument the actual capital gains and dividend payments with past portfolio weights. Unrealized capital gains lead to a marginal propensity to consume (MPC) of 13 percent for the bottom 50% of the wealth distribution, but a flat 5 percent for the rest of th

Fighting high-modernist stereotypes with postmodern weaponry. Academic hostility

Lucky Jim, 1954, by Kingsley Amis, is considered by everyone an extremely funny academic novel; a novel of the genre. A third millennium close reading may uncover, however, side-meanings at the time of publication which, in the meantime, have become central meanings. The humoristic ingredient of the novel has dwindled dramatically, whereas the underestimated conflict between modernist rituals and
