Pituitary dysfunction after aneurysmal subarachnoid hemorrhage is associated with impaired early outcome

Objective Poor outcome and neuropsychological sequelae after aneurysmal subarachnoid hemorrhage (SAH) is a persistent problem. Pituitary dysfunction has been proposed as a contributing factor. Clinical studies have given variable and conflicting results on its importance and incidence after SAH. The aim of this study was to prospectively examine SAH patients with assessment of endocrine function i

Navigating Information Overload Caused by Automated Testing – A Clustering Approach in Multi-Branch Development

Background. Test automation is a widely used technique to increase the efficiency of software testing. However, executing more test cases increases the effort required to analyze test results. At Qlik, automated tests run nightly for up to 20 development branches, each containing thousands of test cases, resulting in information overload. Aim. We therefore develop a tool that supports the analysis

Using remote sensing to model carbon source/sink dynamics in the sahel

Recent research has identified the grasslands of the Sahel as a potential carbon sink, but regional carbon stock accounting in such biomes is undermined by the poorly recognized role they play in the carbon cycle as well as lack of data. In this paper, we demonstrate the feasibility of coupling the satellite data-driven light use efficiency model (Lund University Light Use Efficiency Model - LULUE

A comparison between the microflora of Herrgård cheese from three different dairies

The microflora of Herrgård cheese produced at three dairies was grouped by phenotypical key tests and typed by randomly amplified polymorphic DNA (RAPD). Ten cheeses from the same vat at each dairy were analysed, five after 3 and another five after 6 months of ripening. All cheeses were organoleptically graded as Herrgård after uniform national standards, and only small but characteristic differen

Neural networks, multitemporal landsat thematic mapper data and topographic data to classify forest damages in the Czech republic

This study uses multitemporal Landsat Thematic Mapper data and topographic data for the purpose of classifying coniferous forest damage in the Czech Republic using an artificial neural network. Comparing the neural network-based classification with earlier studies and a multinominal logistic regression using identical training and test data indicates that the back propagation algorithm is comparab

Heat transfer analysis of a traction machine with directly cooled laminated windings

A directly enhanced cooled winding in an electrical traction machine has the potential to extend the operation range, which is in particular attractive for a traction application when operating near peak power for extended periods of time. This paper presents the heat transfer analysis of a modular machine segment with a laminated winding. The laminated winding has a great potential when it comes

Reliability and validity of the Swedish version of the Self-Efficacy for Rehabilitation outcome scale in persons with knee osteoarthritis

Objective: To examine reliability and validity of the Swedish version of the Self-Efficacy for Rehabilitation (SER) outcome scale. Methods: One-hundred and ninety-eight inpatients (mean age 69 years) who underwent a primary total knee arthroplasty (TKA) due to knee osteoarthritis participated. They responded pre- and postoperatively to the SER outcome scale, and preoperatively to the Hospital Anxi

Radiocarbon and hydrocarbon analysis of pm sources during whtc tests on a biodiesel-fueled engine

PM in diesel exhaust has been given much attention due to its adverse effect on both climate and health. As the PM emission levels are tightened, the portion of particles originating from the lubrication oil is likely to increase. In this study, exhausts from a biodiesel-fueled Euro 5 engine were examined to determine how much of the carbonaceous particles that originated from the fuel and the lub

Radiography - How do students understand the concept of radiography?

Background: Radiography as a concept has mainly been associated with the functional role of the radiographer. The concept has been studied from a theoretical point of view. However, there is a lack of a theoretical foundation and research on the actual substance of the term radiography used in education. It is therefore important to undertake an investigation in order to determine how students aft

Mixing in wall-jets in a heavy-duty diesel engine : A les study

The paper presents a large eddy simulation investigation on the effect of fuel injection pressure on mixing, in an optical heavy-duty diesel engine. Recent investigation on impinging wall jets at constant-volume and quiescent conditions exhibited augmented air entrainment in wall jets with increasing injection pressure, when compared with a free jet. The increased mixing rates were explained as ow

How Local are Spatial Density Externalities? Neighbourhood Effects in Agglomeration Economies

Andersson M., Klaesson J. and Larsson J. P. How local are spatial density externalities? Neighbourhood effects in agglomeration economies, Regional Studies. The geographic scale at which density externalities operate is analysed in this paper. Using geocoded high-resolution data, the analysis is focused on exogenously determined within-city squares (‘neighbourhoods’) of 1 km2. The analysis confirm

Effects of extracts of apple peel from organically and integrated production cultivated apples and ursolic acid on cancer cell proliferation

The effects of extract of apple peel, 'Aroma', organically cultivated or cultivated according to integrated production, on cell proliferation in vitro of colon cancer HT29 cells and breast cancer MCF-7 cells, were investigated. Different sequences of solvents were used, and the inhibiting effect on cancer cell proliferation of the different extracts was investigated. The solvents used were ethanol

Parameter Selection in the Parameter Estimation of Grade Transitions in a Polyethylene Plant

A polyethylene plant at Borealis AB is modelled in the Modelica language and considered for parameter estimations at grade transitions. Parameters have been estimated for both the steady-state and the dynamic case using the JModelica.org platform, which offers tools for steady-state parameter estimation and supports simulation with parameter sensitivies. The model contains 31 candidate parameters,

Moder Hesselblad och ekumeniken

Med anledning av den nära förestående helgonförklaringen av Elisabeth Hesselblad skriver nu Yvonne Maria Werner, professor på Historiska institutionen vid Lunds universitet, om moder Hesselblads syn på kristen enhet. Hur såg egentligen Elisabeth Hesselblad på ekumeniken? Vad är sant – och vad är myt? Yvonne Maria Werner reder ut begreppen.
