Optimal shape of a cold-neutron triple-axis spectrometer

We have performed a McStas optimization of the primary spectrometer for a generic 40 m long, cold-neutron triple-axis spectrometer with a doubly focusing monochromator. The optimal design contains an elliptically focusing guide, a virtual source point before a low-grade PG monochromator, and non-equidistant focusing at the monochromator. The flux at 5 meV shows a gain factor 12 over the "classical

Time perspective and mental health continuum: What are the time perspective profiles of flourishing, moderately mentally healthy, and languishing individuals?

Time perspective (TP) refers to individuals’ ways of constructing, reconstructing, and relating the psychological concepts of past, present,and future, and provides individuals with a coherence of experiences over time. In the present study, the relationships among five TPs (past negative, past positive, present fatalistic, present hedonistic, and future) were studied in a student sample (N = 280)

A Virtual Sensor for Predicting Diesel Engine Emissions from Cylinder Pressure Data

Cylinder pressure sensors provide detailed information on the diesel engine combustion process. This paper presents a method to use cylinder-pressure data for prediction of engine emissions by exploiting data-mining techniques. The proposed method uses principal component analysis to reduce the dimension of the cylinder-pressure data, and a neural network to model the nonlinear relationship betwee

Water Sorption and Glass Transition of Pig Gastric Mucin Studied by QCM-D.

Hydration of films of pig gastric mucin was studied using a quartz crystal microbalance with dissipation monitoring (QCM-D) equipped with a humidity module. As a prerequisite, the water adsorption isotherm of a clean silica surface was determined. Atomic force microscopy was used to characterize the changes occurring on the silica surface after repeated sorption/desorption and cleaning cycles. The

Pictorial Primates: A Search for Iconic Abilities in Great Apes

Pictures and other iconic media are used extensively in psychological experiments on nonhuman primate perception, categorisation, etc. They are also used in everyday interaction with primates, and as pure entertainment. But in what ways do primates understand iconic artefacts? What implications do these different ways have for the conclusions we can draw from those studies on perception and catego

Two-particle Bose-Einstein correlations in pp collisions at [Formula: see text] 0.9 and 7 TeV measured with the ATLAS detector.

The paper presents studies of Bose-Einstein Correlations (BEC) for pairs of like-sign charged particles measured in the kinematic range [Formula: see text] 100 MeV and [Formula: see text] 2.5 in proton collisions at centre-of-mass energies of 0.9 and 7 TeV with the ATLAS detector at the CERN Large Hadron Collider. The integrated luminosities are approximately 7 [Formula: see text]b[Formula: see te

(ii) Nerve injuries

A peripheral nerve can be injured in different ways, varying from a simple nerve compression, a complete transection or laceration and also as traction lesions such as brachial plexus injuries (including avulsion of spinal nerve roots). A thorough history and examination of the patient is crucial to make a correct diagnosis of the lesion, so that the correct treatment can be initiated immediately.

Hunden under forntiden : nära kompanjoner i livet och döden

Vi berättar om ett flertal fynd av riktigt gamla hundar från Europa och Asien samt presenterar några av våra svenska exempel. Vi utnyttjar kunskaper från arkeologi och osteologi (läran om skelettet) och tolkar förhållandet mellan hund och människa från allra äldsta stenålder. Vi beskriver också vad som generellt sker med en djurart fysiskt när den tämjs och anpassar sig till ett liv med oss männis

Adsorption of methanol on Ni3Al(111) and NiAl(110): A high resolution PES study

The adsorption of methanol on Ni3Al(1 1 1) and NiAl(1 1 0) has been studied using high resolution photoemission spectroscopy (HR-PES) and density functional theory (DFT). Both methanol and methoxy are formed on these surfaces after the initial methanol exposure at low temperatures. Heating to 200 K leads to further formation of methoxy. On NiAl(1 1 0) two different methoxy species are observed whe

Applicability of Parallel Plate Avalanche Counters to Spontaneous Fission from Cf-252

The construction and performance of the parallel plate avalanche counters (PPACs) using a spontaneous fission source Cf-252 is described in this paper. The parallel plate circular electrodes are made of aluminum foils having a thickness less than ten microns. After fabrication, the detectors and the source are mounted inside a reaction chamber, the source between the two detectors. A low pressure

Från Spadarvet till Kokapell: Jordbruk och skogsbruk i konsten

I artikeln görs en översikt över jordbrukets och skogsbrukets närvaro i konsten i Sverige under 1900-talet. Den innehåller också analyser och diskussioner rörande hur, när och varför det agrara motivet är närvarande alternativt frånvarande i konsten under perioden.

Coherent Picosecond Exciton Dynamics in a Photosynthetic Reaction Center

Photosynthetic reaction centers convert sunlight into a transmembrane electrochemical potential difference, providing chemical energy to almost all life on earth. Light energy is efficiently transferred through chromophore cofactors to the sites, where charge separation occurs. We applied two-dimensional electronic spectroscopy to assess the role of coherences in the photoresponse of the bacterial

Swedish hunters' safety behaviour and experience of firearm incidents

Since any firearm injury is potentially lethal, it is of great interest to prevent firearm incidents. This study investigated such incidents during hunting and Swedish hunters' safety behaviour. A 48-item questionnaire was posted to a random sample of 1000 members of the Swedish Association for Hunting and Wildlife Management. The questions considered demographics, hunting experience/hunting habit

Towards more prognostic information to patients with life threatening diseases: Why, how and when?

Physicians’ attitudes towards disclosure to patients of cancer diagnoses have changed from non-disclosure to full disclosure. Also disclosure of prognosis are likewise said to have changed, though not to the same degree. The overriding aim of this dissertation is to analyse information disclosed to patients with severe cancer prognoses, from a Swedish perspective, through two sets of interviews wi

Recurrent acute otitis media - aetiology, diagnostics and prevention

Popular Abstract in Swedish Akut mediaotit - öroninflammation - är den vanligaste bakteriella infektionen hos barn. Den vanligaste öroninflammationsbakterien är pneumokocken. Öroninflammation är en infektion som varierar stort i svårighetsgrad; medan många öroninflammationer läker utan behandling kan andra ge upphov till livshotande komplikationer. Eftersom självläkningsfrekvensen är ganska hög oAcute otitis media (AOM) is the most common bacterial infection in children. The clinical course varies from spontaneous recovery to life-threatening complications, and this variability mainly depends on the causative pathogen. Bacteria usually invade the middle ear from the nasopharynx, where they are carried frequently, both during sickness and health. The most common bacterium to cause AOM, and

Modelling uncertainty for nitrate leaching and nitrous oxide emissions based on a Swedish field experiment with organic crop rotation

High uncertainties are common in detailed quantification of the N budget of agricultural cropping systems. The process-based CoupModel, integrated with the parameter calibration method known as Generalized likelihood uncertainty estimation (GLUE), was used here to define parameter values and estimate an N budget based on experimental data from an organic farming experiment in south-west Sweden. Da

Body mass changes in a biparental incubator: the Redshank Tringa totanus

Incubation is a period of high energetic costs and accordingly body mass losses are often detected. Why birds lose body mass during incubation is not well understood; suggestions are that it is either a consequence of energetic constraints or adaptations to an optimal mass trajectory. We studied body mass changes through the incubation period in the Common Redshank Tringa totanus, a biparental inc
