Late Pleistocene glacial history of Jameson Land, central East Greenland, derived from cosmogenic (10)Be and (26)Al exposure dating

Abstract in Undetermined Previous work has presented contrasting views of the last glaciation on Jameson Land, central East Greenland, and still there is debate about whether the area was: (i) ice-free, (ii) covered with a local non-erosive ice cap(s), or (iii) overridden by the Greenland Ice Sheet during the Last Glacial Maximum (LGM). Here, we use cosmogenic exposure ages from erratics to reconc

Discounting and clinical decision making: physicians, patients, the general public, and the management of asymptomatic abdominal aortic aneurysms.

Clinical decisions often entail in intertemporal trade-off. Moreover, they often involve physicians of different specialities. In an experiment dealing with the management of small asymptomatic abdominal aortic aneurysms (a clinically relevant problem) we find that specialists in internal medicine exhibit higher implicit discount rates than vascular surgeons, general practitioners, and actual and

Health care, social care or both? A qualitative explorative study of different focuses in long-term care of older people in France, Portugal and Sweden

Challenges with an ageing population are increasingly becoming a reality in the Western world. Since cognitive impairment increases with age, we can expect an increasing number of older people in need of care. The aim of this article is to describe, analyse and compare different focuses on care of older people with dementia, using examples from France, Portugal and Sweden. The questions are princi

Preeclampsia--abnormal uterine artery Doppler is related to recurrence of symptoms during the next pregnancy.

Background: Impaired trophoblast invasion is suggested as the main cause of reduced placental perfusion, which results in fetal growth restriction and preeclampsia. Immunological response against the invading tissue has been given as the explanation. Preeclampsia frequently recurs during the next pregnancy. Doppler ultrasound can predict increased vascular impedance in the uteroplacental circulati

Retinal progenitor cell xenografts to the pig retina: immunological reactions.

We evaluated the host response to murine retinal progenitor cells (RPCs) following transplantation to the subretinal space (SRS) of the pig. RPCs from GFP mice were transplanted subretinally in 18 nonimmunosuppressed normal or laser-treated pigs. Evaluation of the SRS was performed on hematoxylin-cosin (H&E)-stained sections. Serum samples were taken from naive and RPC-grafted pigs and mouse-r

The influence of backscatter material on 99mTc and 201Tl line source responses

SPECT projections are contaminated by scatter, resulting in reduced image contrast and quantitative errors. When tissue is present behind the source, some of the detected photons backscatter via this tissue. Particularly in dual-isotope SPECT and in combined emission-transmission SPECT, backscatter constitutes a major part of the down-scatter contamination in lower-energy windows. In this paper, t

A novel FISH assay for SS18-SSX fusion type in synovial sarcoma

Synovial sarcoma is a morphologically, clinically and genetically distinct entity that accounts for 5-10% of all soft tissue sarcomas. The t(X;18)(p11.2;q11.2) is the cytogenetic hallmark of synovial sarcoma and is present in more than 90% of the cases. It produces three types of fusion gene formed in part by SS18 from chromosome 18 and by SSX1, SSX2 or, rarely, SSX4 from the X chromosome. The SS1

Bioreactor control using a probing feeding strategy and mid-ranging control

The paper presents a fed-batch fermentation technique for bioreactors operating close to their maximum oxygen transfer capacity. The method combines the advantages of the probing feeding strategy and the temperature limited fed-batch technique. When the maximum oxygen transfer capacity of the reactor is reached, the temperature is decreased to lower the oxygen demand. To achieve a good control of

Phylogeny of cetrarioid lichens (Parmeliaceae) inferred from ITS and beta-tubulin sequences, morphology, anatomy and secondary chemistry.

Phylogenetic relationships within the family Parmeliaceae (lichenized ascomycetes) with emphasis on the heterogeneous group of cetrarioid lichens are reconstructed. The results are based on cladistic analyses of DNA-sequences, morphological and chemical data. Almost all currently recognized cetrarioid genera were included in the analyses together with parmelioid and alectorioid members of the pres

Anaerobic batch digestion of solid potato waste alone and in combination with sugar beet leaves

The objective of this study was to characterise anaerobic batch biodegradation of potato waste alone and when co-digested with sugar beet leaves. The effects of increasing concentration of potato waste expressed as percentage of total solids (TS) and the initial inoculum-to-substrate ratio (ISR) on methane yield and productivity were investigated. The ISRs studied were in the range 9.0-0.25 and in

Wheelchair users and public transit : Eliciting ascriptions of comfort and safety

Transport policies often contain explicit goals for the travel quality of disabled passenger groups. Addressing the user perspective, focus group discussions with wheelchair-seated passengers (using bus transit and Special Transportation Services) were therefore held, in order to qualitatively explore perceived comfort and safety - two important quality factors. The comfort and safety constructs w

Synthesis - Regime change for nanowire growth

Gold nanoparticles are routinely used as 'seeds' to grow semiconductor nanowires and it has now been discovered that the nanowires grow faster when the gold seeds are placed closer together.

Identifying potentials for reducing uncertainty in critical load calculations using the PROFILE model

A sensitivity analysis was performed testingweathering rates, critical loads andexceedances for Swedish forest soils using Monte Carlosimulations of the PROFILE model. Different subsetsof input data were investigated with respect to theirpotential to reduce data uncertainty at site level butalso for modified estimates of the 5%-ile critical load andthe 95%-ile exceedance on 150×150 kmresolution. P

Electron-Hole Duality and Vortex Rings in Quantum Dots

In a quantum-mechanical system, particle-hole duality implies that instead of studying particles, we can get equivalent information by studying the missing particles, the so-called holes. Using this duality picture for fermions in a rotating trap the vortices appear as holes in the Fermi sea. Here we predict that the formation of vortices in quantum dots at high magnetic fields causes oscillations

Boronate-containing polymers form affinity complexes with mucin and enable tight and reversible occlusion of mucosal lumen by poly (vinyl alcohol) gel

Copolymers of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with N,N-dimethylarcrylamide (DMAA) formed insoluble interpolymer complexes with mucin from porcine stomach at pH 9.0. The complex formation based on boronate-sugar interactions took place between the similarly charged macromolecules and resulted in coacervate particles formation, which depended both on pH and ionic strength of the soluti

Factors important for good interaction in physiotherapy treatment of persons who have undergone torture: A qualitative study.

Torture can be defined as the deliberate or systematic infliction of physical or mental suffering to force another person to yield information, as a punishment or to destroy a person's identity. The aim of the physiotherapy treatment for persons who have undergone torture is to relieve or reduce pain, correct musculoskeletal dysfunctions, teach the client to cope with pain, and regain body awarene

Clinical spectrum of hepatitis C-related liver disease and response to treatment with interferon and ribavirin in haemophilia or von Willebrand disease

Our aim was to evaluate the severity of liver disease resulting from chronic hepatitis C in haemophilia or von Willebrand disease and the efficacy of 6 months treatment with interferon alpha and ribavirin. Fifty-five liver biopsies were performed in 43 patients without any bleeding complications, as seen with ultrasound immediately after the biopsy and 48 h thereafter. Histological changes were mi

Metabolism of [C-14] glutamate and [C-14] glutamine by the ectomycorrhizal fungus Paxillus involutus

To examine pathways of glutamate and glutamine metabolism in the ectomycorrhizal fungus Paxillus involutus, tracer kinetic experiments were performed using L-[U-C-14]glutamate and L-[U-C-14]glutamine and the enzyme inhibitors methionine sulfoximine (MSX), azaserine (AZA) and aminooxyacetate (AOA). When [C-14]glutamate was supplied to fungal cultures, 25% of the radioactivity of the amino acid frac

Does inequality in self-assessed health predict inequality in survival by income? - Evidence from Swedish data

This paper empirically addresses two questions using a large, individual-level Swedish data set which links mortality data to health survey data. The first question is whether there is an effect of an individual's self-assessed health (SAH) on his subsequent survival probability and if this effect differs by socioeconomic factors. Our results indicate that the effect of SAH on mortality risk decli
