Effects of graphene ethylene glycol/water nanofluids on the performance of a brazed plate heat exchanger
Effects of graphene ethylene glycol/water nanofluids as the hot side fluid on heat transfer and pressure drop characteristics in a brazed plate heat exchanger (BPHE) were experimentally investigated. Nanofluid properties, especially thermal conductivity and viscosity of the graphene nanofluids were measured at various graphene concentrations (0.01 to 1.0% wt.) and temperatures (10 to 60 °C). Dimen
Evaluation of Potential Effects of NaCl and Sorbic Acid on Staphylococcal Enterotoxin A Formation
The prophage-encoded staphylococcal enterotoxin A (SEA) is recognized as the main cause of staphylococcal food poisoning (SFP), a common foodborne intoxication disease, caused by Staphylococcus aureus. Studies on the production of SEA suggest that activation of the SOS response and subsequent prophage induction affect the regulation of the sea gene and the SEA produced, increasing the risk for SFP
Att skapa en bättre arbetsmiljö i hemtjänsten: Hur arbeta med participativt förändringsarbete i praktiken?
I dag arbetar cirka 22 procent av de arbetande kvinnorna i Sverige i vård och omsorgssektorn. Vård och omsorg är en kvinnodominerad sektor som karaktäriseras av höga sjuktal, hög personalomsättning och rekryteringsproblem. Sveriges befolkning blir allt äldre samtidigt som vården av svårt sjuka patienter i allt högre grad flyttas ut från sjukhusen till hemmet. Detta utgör stora utmaningar för hemtj
Neutron diffraction measurements on a reference metallic sample with a high-efficiency GEM side-on 10B-based thermal neutron detector
The upgraded version of the GEM side-on thermal neutron detector was successfully tested in a neutron diffraction experiment on a reference sample using the INES diffractometer at the ISIS spallation neutron source, UK. The performance of the new 10B4C-based detector is compared to that of a standard 3He tube, operating at the instrument as a part of the detectors assembly. The results show that t
Search for a new heavy gauge-boson resonance decaying into a lepton and missing transverse momentum in 36 fb - 1 of pp collisions at √s=13 TeV with the ATLAS experiment
The results of a search for new heavy W′ bosons decaying to an electron or muon and a neutrino using proton–proton collision data at a centre-of-mass energy of s=13 TeV are presented. The dataset was collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 36.1 fb-1. As no excess of events above the Standard Model prediction is

Physical properties of the heterojunction MoOx/n-CdTe as a function of the parameters of CdTe crystals
MoOx/n-CdTe photosensitive heterostructures were prepared by the deposition of molybdenum oxide thin films onto three different n-type CdTe substrates (ρ1=0.4 Ωfirst>cm, ρ2=10 Ωfirst>cm, ρ3=40 Ωfirst>cm) by DC reactive magnetron sputtering. The height of the potential barrier and series resistance of the MoOx/CdTe heterojunctions were investigated. The dominating current transport mechanisms throu
Blood parasites shape extreme major histocompatibility complex diversity in a migratory passerine
Pathogens are one of the main forces driving the evolution and maintenance of the highly polymorphic genes of the vertebrate major histocompatibility complex (MHC). Although MHC proteins are crucial in pathogen recognition, it is still poorly understood how pathogen-mediated selection promotes and maintains MHC diversity, and especially so in host species with highly duplicated MHC genes. Sedge wa
Feasibility of music and hypnotic suggestion to manage chronic pain.
Bilateral electrodermal activity in the active-alert hypnotic induction
Shifts in hemispheric dominance were previously proposed to play a role in hypnosis. Participants (N = 32) were exposed to an active–alert hypnosis induction and a music-control condition while electrodermal activity was registered bilaterally, providing information on alterations in hemispheric dominance. The results suggest that highly hypnotizable participants show a shift to right-sided and lo

Satellite passive microwaves reveal recent climate-induced carbon losses in African drylands
The African continent is facing one of the driest periods in the past three decades as well as continued deforestation. These disturbances threaten vegetation carbon (C) stocks and highlight the need for improved capabilities of monitoring large-scale aboveground carbon stock dynamics. Here we use a satellite dataset based on vegetation optical depth derived from low-frequency passive microwaves (
Woody plant cover estimation in drylands from Earth Observation based seasonal metrics
From in situ measured woody cover we develop a phenology driven model to estimate the canopy cover of woody species in the Sahelian drylands at 1km scale. The model estimates the total canopy cover of all woody phanerophytes and the concept is based on the significant difference in phenophases of dryland trees, shrubs and bushes as compared to that of the herbaceous plants. Whereas annual herbaceo
Global-scale mapping of changes in ecosystem functioning from earth observation-based trends in total and recurrent vegetation
Aim: To evaluate trend analysis of earth observation (EO) dense time series as a new way of describing and mapping changes in ecosystem functioning at regional to global scales. Spatio-temporal patterns of change covering 1982-2011 are discussed in the context of changes in land use and land cover (LULCC). Location: Global. Methods: This study takes advantage of the different phenological cycles o
