A Proposed Middle-Range Theory of Nursing in Hypertension Care

Nursing in hypertension care comprises counselling about lifestyle changes, blood pressure measurement, and being a translator for the physician. For the patient, changing lifestyle means performing self-care. As not much in the form of research and guidelines for nurses is available, a middle-range theory of nursing in hypertension care was developed to guide nurses in their practice, in order to

Quantum Szilard Engine with Attractively Interacting Bosons

We show that a quantum Szilard engine containing many bosons with attractive interactions enhances the conversion between information and work. Using an ab initio approach to the full quantum-mechanical many-body problem, we find that the average work output increases significantly for a larger number of bosons. The highest overshoot occurs at a finite temperature, demonstrating how thermal and qu

Cross laminated timber at in-plane beam loading - Prediction of shear stresses in crossing areas

Cross Laminated Timber (CLT) at in-plane beam loading conditions present a very complex stress state and many failure modes need to be considered in design. The work presented here aims at finding improvements of a specific analytical model for stress analysis and strength verification that has been suggested in literature and which is also suggested as a basis for design equations for the next ve

TRIM28 and the control of transposable elements in the brain

TRIM28 is an epigenetic co-repressor protein that mediates transcriptional silencing. TRIM28 participates, together with the large family of Kruppel-associated box domain zinc finger proteins (KRAB-ZFP) transcription factors, in the repression of transposable elements (TE). Recent advances indicate that TRIM28-based repression of TEs occurs in the mammalian brain and may provide beneficial effects

Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans

Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. This thesis describes how different types of DF and fat levels, can alter BA composition in the caecum/faeces an

The effects of aerobic exercise for persons with migraine and co-existing tension-type headache and neck pain. A randomized, controlled, clinical trial

Aim: To evaluate aerobic exercise in migraine and co-existing tension-type headache and neck pain. Methods: Consecutively recruited persons with migraine and co-existing tension-type headache and neck pain were randomized into an exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 minutes, three times/week. Controls continued usual daily activitie

On the Modelling of Thermo-Viscoplasticity of Case-Hardening Steels Over a Wide Temperature Range

The aim of this work is the development of a thermodynamically consistent fully coupled thermo-viscoplastic material model for metals.The model is based on a split of the free energy into a thermo-elastic, a thermo-plastic and a purely thermal part and covers nonlinear cold-work hardening and thermal softening.Nonlinear temperature dependent effects are accounted for the elastic moduli, the plasti

Modelling Thermo-Viscoplasticity of Case-Hardening Steels Over Wide Temperature Ranges

The aim of this work is the development of a thermodynamically consistent fully coupled thermoviscoplastic material model for metals, especially for case hardening steels.The model is based on a split of the free energy into a thermo-elastic, a purely plastic and a purely thermal part and covers nonlinear cold-work hardening and thermal softening.Effects arising from phase transformations at auste

The influence of hazardous drinking on psychological functioning, stress and sleep during and after treatment in patients with mental health problems : a secondary analysis of a randomised controlled intervention study

OBJECTIVES: Hazardous drinking could negatively affect health and lead to alcohol use disorders, but it is unclear how hazardous drinking affects treatment outcomes of depression and anxiety and stress-related mental health problems. The aim of this study was to examine whether hazardous drinking, measured by Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), influences the outcomes

Genome-wide interaction study of smoking behavior and non-small cell lung cancer risk in Caucasian population

Non-small cell lung cancer is the most common type of lung cancer. Both environmental and genetic risk factors contribute to lung carcinogenesis. We conducted a genome-wide interaction analysis between single nucleotide polymorphisms (SNPs) and smoking status (never- versus ever-smokers) in a European-descent population. We adopted a two-step analysis strategy in the discovery stage: we first cond

Altered peripheral amino acid profile indicate a systemic impact of active celiac disease and a possible role of amino acids in disease pathogenesis

Background: We have previously performed a Genome Wide Association and linkage study that indicated a new disease triggering mechanism involving amino acid metabolism and nutrient sensing signaling pathways. Objective: The aim of this study was to investigate if plasma amino acid levels differed among children with celiac disease compared with disease controls. Materials and methods: Fasting plasm

HnRNP G prevents inclusion on the HPV16 L1 mRNAs of the central exon between splice sites SA3358 and SD3632

HPV16 late L1 mRNAs encode a short central exon that is located between HPV16 3′-splice site SA3358 and HPV16 5′-splice site SD3632. While SA3358 is used to produce both HPV16 early mRNAs encoding the E6 and E7 oncogenes, and late mRNAs encoding E4, L1 and L2, SD3632 is used exclusively to produce late L1 mRNA. We have previously identified an 8-nucleotide regulatory RNA element that is required f

Facilitated sequence assembly using densely labeled optical DNA barcodes : A combinatorial auction approach

The output from whole genome sequencing is a set of contigs, i.e. short non-overlapping DNA sequences (sizes 1-100 kilobasepairs). Piecing the contigs together is an especially difficult task for previously unsequenced DNA, and may not be feasible due to factors such as the lack of sufficient coverage or larger repetitive regions which generate gaps in the final sequence. Here we propose a new met

Anharmonicity of a superconducting qubit with a few-mode Josephson junction

Coherent operation of gate-voltage-controlled hybrid transmon qubits (gatemons) based on semiconductor nanowires was recently demonstrated. Here we experimentally investigate the anharmonicity in epitaxial InAs-Al Josephson junctions, a key parameter for their use as a qubit. Anharmonicity is found to be reduced by roughly a factor of 2 compared to conventional metallic junctions and dependent on
