We present extensive density-functional theory (DFT) based calculations of the clean Rh(111) surface and of CO/Rh(111) overlayer systems. We study both ground-state structural properties and core-level shifts from differences in total energies at different coverages and adsorption sites. Most results are obtained using using norm-conserving or ultrasoft pseudopotentials. The overall reliability of

Objective: Pain measurement is a necessity in pain treatment but can be difficult in young children. The aim of this study was to evaluate the validity and reliability of the Behavioural Observational Pain Scale (BOPS) as a postoperative pain measurement scale for children aged 1-7 yrs. The scale assesses three elements of pain behaviors: facial expression, verbalization, and body position. Design

Popular Abstract in Swedish Gel-dosmätningar för kontroll av strålbehandling av cancertumörer När en patient strålbehandlas avser man att bestråla sjuka områden i kroppen. Det är dock omöjligt att göra detta utan att därmed även till viss del stråla på omkringliggande organ och komplikationer kan då uppstå. För att minimera dessa bieffekter och optimera behandlingen används ofta en så kallad dospGel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. Single clinical electron and photon beams were evaluated and gel dose distributions were mainly w

Tänk om du levde i en värld med ett stabilt klimat där fler företag bedrev sin verksamhet utefter cirkulära affärsmodeller. Ett samhälle som anammat mer hållbara konsumtionsbeteenden, skapat fler arbetstillfällen, och äntligen slutat utarma Jordens naturresurser. Vore inte det en härlig tillvaro? Vill vi förverkliga drömmen bör vi ställa oss frågan vad som krävs för att vi ska komma dit. Mer speciThe shortage of Earth’s limited resources is becoming more evident and our planet’s climate system is under immense pressure. To combat these problems, more people investigate the concept of circularity. This study intended to find out what make consumers motivated to buy used items from a professional refurbisher, thereby replacing purchases of brand-new products, and also identifying barriers.

Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. To gain a better understanding of the Arctic carbon cycle in the future, global dynamic vegeta

Introduction: Rockwell Automation needs to understand how a lean company wants to visualize different KPIs. Ambu wants to see the value of using such visualization in their company and the effect it might have.Thus the two parts fulfill each other's needs and are the perfect match. Purpose: The purpose of the master thesis is to identify essential KPIs in a medical production process and desi

Elbilars utveckling går fort framåt och fler väljer att investera i en. Vilka olika laddningstekniker finns det? Hur kommer laddningen av elbilar påverka våra elnät? Kraftdistribution till en elvägssträcka modelleras för att påvisa kapacitetskrav och kostnader. Studien visar även hur hemmaladdning och arbetsplatsladdning kan påverka belastningen i elnätet om reglering uteblir.Sweden’s road traffic is responsible for a great part of the emissions of greenhouse gases in the country. Conventional vehicles, driven by fossil fuels, have low efficiency and emits environmentally destructive particles. Electric vehicles can be the solution! Electric vehicles have no local emissions while driving and the electric motors of today have an efficiency of above 90 %. But there are s

Flow injection analysis provides a convenient platform for the use of biosensors in the monitoring of bio-processes. A major requirement in bioprocess monitoring is real time information about various process parameters like concentration of products and substrates, flow rates, and injection volumes. Depending on the application, the monitoring requirements vary and this results in a need for diff

The Gaia satellite, to be launched in August 2012, will measure highly accurate absolute parallaxes of hundreds of millions of stars. This is done by comparing parallactic displacement of stars in different parts of the sky. The accuracy of this method highly depends on the stability of the so-called basic angle between the two fields of view of the Gaia instrument, and periodic variations could l

The aim of this study was to investigate potential dose reductions to the heart, left anterior descending coronary artery (LAD), and ipsilateral lung for left-sided breast cancer using visually guided deep inspiration breath-hold (DIBH) with the optical surface scanning system Catalyst™, and how these potential dosimetric benefits are affected by intrafractional motion in between breath holds. For

BACKGROUND: Impaired olfaction is an important feature in Parkinson's disease (PD) and other neurological diseases. A variety of smell identification tests exist such as "Sniffin' Sticks" and the University of Pennsylvania Smell Identification Test (UPSIT). An important part of research is being able to replicate findings or combining studies in a meta-analysis. This is difficult if olfaction has

Methylenetetrahydrofolate reductase (MTHFR) protein catalyzes the only biochemical reaction which produces methyltetrahydrofolate, the active form of folic acid essential for several molecular functions. The Ala222Val polymorphism of human MTHFR encodes a thermolabile protein associated with increased risk of neural tube defects and cardiovascular disease. Experimental studies have shown that the

The aim of this study was to evaluate the prognostic value of Ki67 in relation to established prognostic factors in lymph node-negative breast cancer, and furthermore, whether the prognostic impact was dependent on estrogen receptor (ER) status and histological grade. In 200 premenopausal patients, with 5 years of follow-up, Ki67 was determined on tissue microarrays. In univariate analysis, Ki67 (

Background: Breast-reduction techniques are increasingly used in oncoplastic breast surgery. Bilateral therapeutic mammoplasty has the benefit of decreasing breast volume, enabling resection of larger tumors, and the potential to assure good postoperative symmetry. The aims of this study were to objectively asses the cosmetic outcomes of therapeutic mammoplasty in patients with breast cancer, usin

The PID controller is by far the most popular controller for process control in industry today [Åström and Murray, 2008]. The combination of its relatively simple usage and its satisfactory results within several areas has gained its popularity [Visioli, 2006]. However, the tuning of the controller is crucial. An automatic tuning method was developed by [Åström and Hägglund, 1984] in the mid-eight
