Vacuum diffusion-bonded printed circuit heat exchangers are an attractive choice for the high-temperature, high-pressure demands of next-generation energy applications. However, early reports show that the high-temperature materials desired for these applications suffer from poor bond strengths due to precipitation at the bond line, preventing grain boundary migration. In this study, a diffusion b
Real-time PCR is fast, sensitive, specific, and can deliver quantitative data; however, two disadvantages are that this technology is sensitive to inhibition by food and that it does not distinguish between DNA originating from viable, viable nonculturable (VNC), and dead cells. For this reason, real-time PCR has been combined with a novel discontinuous buoyant density gradient method, called flot
Objective. To compare the effect of intraarticular injections of hyaluronan and placebo (vehicle, saline) in patients with knee pain on exertion and with joint cartilage abnormalities. Methods. Fifty-two patients with arthroscopically verified deep cartilage fissures and villus-like flakes in the symptomatic knee were randomly assigned to receive intraarticular injections of 2.5 ml of either hyalu
This study compares the time required to activate a grasp or function of a hand prosthesis when using an electromyogram (EMG) based control scheme and when using a control scheme combining EMG and control signals from an inductive tongue control system (ITCS). Using a cross-over study design, 10 able-bodied subjects used a computer model of a hand and completed simulated grasping exercises. The ti
The results of lichenological excursions of the 19th Symposium of Baltic Mycologists and Lichenologists (BMLS) in Latvia, Kurzeme region, 22–26 September 2014, are reported. A list of 290 species is presented, of which 238 are lichenized, 43 lichen-inhabiting, and nine saprotrophic fungi: ninety-one species are new to Latvia, twelve of which (Caloplaca duplicata, Cresporhaphis wienkampii, Ellisemb
Downlink beamforming in Massive MIMO either relies on uplink pilot measurements--exploiting reciprocity and time-division duplexing (TDD) operation, or on the use of a predetermined grid of beams with user equipments reporting their preferred beams, mostly in frequency-division duplexing (FDD) operation. Massive MIMO in its originally conceived form uses the first strategy, with uplink pilots, whe
AIMS: Cardiovascular disease (CVD) is one of the leading causes of mortality and morbidity worldwide, including in Sweden. The main aim of this study was to explore the temporal trends and spatial patterns of CVD in Sweden using spatial autocorrelation analyses.METHODS: The CVD admission rates between 2000 and 2010 throughout Sweden were entered as the input disease data for the analytic processes
The aim of this paper is to critically examine, discuss, draw conclusions, and come up with ideas how to harmonize GIS education in order to realize the envisaged clientele benefits globally. The paper draws experiences and lessons learnt, with examples from ongoing joint GIS MSc programs/courses being implemented in Mozambique, Rwanda, and Uganda. All the five courses (3 in Uganda, 1 in Mozambiqu
A cultivation strategy for the production of two truncated thermostable recombinant xylanases (Xyn1ΔN and Xyn1ΔNC) was developed. Fed-batch cultivations of Escherichia coli strain BL21(DE3) with a controlled exponential glucose feed led to high specific production of the recombinant proteins. Addition of complex nutrients (e.g. Tryptone Soya Broth (TSB)) to the media were shown to increase both th
Maternal effects by which females provide their offspring with non-genetic factors such as hormones, nutrients and antibodies can have an important impact on offspring fitness. In vertebrates, maternal antibodies (matAb) are transferred from the mother, via the placenta, egg yolk or milk during lactation to offspring until they are 2 weeks (birds), 4-10 weeks (rodents) and 9 months (humans) old, r
This opinion piece takes Google's response to the so-called COVID-19 infodemic, as a starting point to argue for the need to consider societal relevance as a complement to other types of relevance. The authors maintain that if information science wants to be a discipline at the forefront of research on relevance, search engines, and their use, then the information science research community needs
OBJECTIVES: To evaluate activity limitations before and after carpal tunnel release among patients with and without diabetes, to explore differences between genders and the influence of grip strength on activity limitations. DESIGN: Prospective case-control study. PATIENTS: Thirty-three patients with diabetes and carpal tunnel syndrome (CTS) were age and gender matched with 30 patients without d
Popular Abstract in Swedish Syfte: Att undersöka den prediktiva precisionen hos ålder för missbruksdebut, MAO-B aktiviteten i blod, samt olika kombinationer av kriminologiska och kliniska riskfaktorer med avseende på återfall i våldsbrott hos tidigare våldsbrottsdömda i en prospektiv svensk uppföljningsstudie. Studiepopulation: Hundra våldsbrottslingar, konsekutivt intagna för rättspsykiatrisk undObjective: To test the predictive accuracy for violent recidivism of the age at onset of substance abuse, the platelet MAO-B activity, and various combinations of criminological and clinical risk factors among violent offenders in a prospective Swedish follow-up study. Subjects: One hundred violent offenders, consecutively admitted for forensic psychiatric investigations between 1998 and 2001 (bas
När Lissabonfördraget trädde i kraft den 1 december 2009 medförde det viktiga förändringar inom EU:s utrikespolitik. Målet var att öka EU:s samstämmighet i dess externa relationer i syfte att stärka EU:s roll som global aktör. Det nya fördraget inrättade en hög representant för den gemensamma utrikes-och säkerhetspolitiken (HR) samt en assisterande utrikestjänst (EEAS). De nya funktionerna är histThe entry into force of the Lisbon Treaty in December 2009 brought several important changes in the field of EU Foreign Policy. The goal was to enhance coherence in EU external relations to strengthen the role of the EU as a global actor. The creations of the High Representative (HR) of the Union on Foreign Affairs and Security Policy and the assisting European External Action Service (EEAS) are t
The provision of military and armed security services typically is the monopoly domain of the state. With the end of the Cold War legitimate private firms, however, expanded as worldwide providers of military and security services. The proliferation of private military companies echoes back to pre-modern eras when it was customary for state rulers to allocate force and security through the market.
