Imported leishmaniasis in Sweden 1993-2016

In Sweden, leishmaniasis is an imported disease and its epidemiology and incidence were not known until now. We conducted a retrospective, nationwide, epidemiological study from 1993 to 2016. Probable cases were patients with leishmaniasis diagnoses reported to the Swedish Patient registry, collecting data on admitted patients in Swedish healthcare since 1993 and out-patient visits since 2001. Con

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

Exposure, respiratory symptoms, lung function and inflammation response of road-paving asphalt workers

Background: Controversy exists as to the health effects of exposure to asphalt and crumb rubber modified (CRM) asphalt, which contains recycled rubber tyres. Objective: To assess exposures and effects on airway symptoms, lung function and inflammation biomarkers in conventional and CRM asphalt road pavers. Methods: 116 conventional asphalt workers, 51 CRM asphalt workers and 100 controls were inve

Aspects of Additional Psychiatric Disorders in Severe Depression/Melancholia: A Comparison between Suicides and Controls and General Pattern.

Objective: Additional and comorbid diagnoses are common among suicide victims with major depressive disorder (MDD) and have been shown to increase the suicide risk. The aim of the present study was first, to investigate whether patients with severe depression/melancholia who had died by suicide showed more additional psychiatric disorders than a matched control group. Second, general rates of como

Start of low temperature reactions detection based on motoring pressure prediction for partially premixed combustion

Partially premixed combustion aims to reduce NOx and particulate matter emission without fuel consumption penalty. Low temperature reactions are important for the partially premixed combustion. In the current study, a self-adaptive strategy is introduced to predict the motoring pressure by means of an equivalent isentropic index. The start of the low temperature reactions is detected when the pres

Genetic variation of acquired structural chromosomal aberrations

Human malignancies are often hallmarked with genomic instability, which itself is also considered a causative event in malignant transformation. Genomic instability may manifest itself as genetic changes in the nucleotide sequence of DNA, or as structural or numerical changes of chromosomes. Unrepaired or insufficiently repaired DNA double-strand breaks, as well as telomere shortening, are importa

May Measurement Month 2017 : an analysis of blood pressure screening results worldwide

Background: Increased blood pressure is the biggest contributor to the global burden of disease and mortality. Data suggest that less than half of the population with hypertension is aware of it. May Measurement Month was initiated to raise awareness of the importance of blood pressure and as a pragmatic interim solution to the shortfall in screening programmes. Methods: This cross-sectional surve

Understanding the Role of Seed Particle Material on III-As Nanowire Growth

III-V semiconductor nanowires have attracted extensive research interests over the past few decades due to their unique geometry and great potential for promoting new functionalities in future electronics, light-emitting diodes and solar cells. However, in order to push this technology beyond the laboratory level, it is essential to combine it with the current Si-based semiconductor industry for a

Coding variants in NOD-like receptors : An association study on risk and survival of colorectal cancer

Nod-like receptors (NLRs) are important innate pattern recognition receptors and regulators of inflammation or play a role during development. We systematically analysed 41 non-synonymous single nucleotide polymorphisms (SNPs) in 21 NLR genes in a Czech discovery cohort of sporadic colorectal cancer (CRC) (1237 cases, 787 controls) for their association with CRC risk and survival. Five SNPs were f

Effects of gravity and variable thermal properties on nanofluid convective heat transfer using connected and unconnected walls

In this paper, heat transfer characteristics of natural convection in an enclosure are investigated by considering variable thermal properties. The heated enclosure with an aspect ratio of unity is full of an alumina-water nanofluid. To analyze the effect of different thermal properties on the flow and temperature distributions, many comparisons are conducted for various cases at various Rayleigh

Bosonic Szilard engine assisted by Feshbach resonances

It was recently found that the information-to-work conversion in a quantum Szilard engine can be increased by using a working medium of bosons with attractive interactions. In the original scheme, the work output depends on the insertion and removal position of an impenetrable barrier that acts like a piston, separating the chambers of the engine. Here, we show that the barrier removal process can

Cooper-pair splitting in two parallel InAs nanowires

We report on the fabrication and electrical characterization of an InAs double-nanowire (NW) device consisting of two closely placed parallel NWs coupled to a common superconducting electrode on one side and individual normal metal leads on the other. In this new type of device we detect Cooper-pair splitting (CPS) with a sizeable efficiency of correlated currents in both NWs. In contrast to earli

Associations between self-injury and involvement in cyberbullying among mentally distressed adolescents in Scania, Sweden

Aims: To investigate associations between self-injury and involvement in cyberbullying as a bully, victim or bully-victim among mentally distressed adolescents. Methods: Data from the public health survey of children and adolescents in Scania, Sweden 2016 were used. A questionnaire was answered anonymously in school by 9143 students in 9th grade compulsory school (response rate 77%) and 7949 stude

Smoking reduces the efficacy of belimumab in mucocutaneous lupus

Objectives: Recently, we demonstrated a negative impact of smoking on belimumab efficacy in patients with systemic lupus erythematosus (SLE). Here, we particularly investigated clinical effects of belimumab and a potential impact of smoking in mucocutaneous and articular SLE. Methods: We surveyed 62 SLE patients treated between 2011 and 2017. Evaluation included the mucocutaneous descriptors of SL

Optical Imaging for Nanowire Mechanics

In this work, we present a stroboscopic detection technique for the study of oscillating nanoscale objects. This optical read-out gives a position accuracy better than 1 nm which is a fraction of both the diffraction limit and the pixel size. The advantage of this stroboscopic method compared to conventional time-averaging techniques, is the time-resolution it provides as well as being non-invasiv

Quantum Transport in Heterostructure Nanowire Devices

This thesis investigates electronic transport in several types of novel heterostructure nanowires. The first part of the thesis focuses on band-to-band mechanisms in heterostructure nanowires for low-power electronics. First, tunnel field-effect transistors (TFETs) based on InP/GaAs heterostructure nanowires with n-i-p doping profile are explored. To further enhance the interband tunneling current

Nanoparticles: Characterization and exposure metrics

Exposure to aerosol nanoparticles has always been present in the evolution of humans, and thus has the human body developed ways of dealing with particles that enters the body. However with the emerging nanotech industry, new types of nanoparticles are being produced and used. Many of these particles have properties never seen before and this rise concern about how exposure to them might cause unw
