Popular Abstract in Swedish Bakgrund För att diagnostisera förändringar i käkbenet är röntgenundersökning av stor betydelse. En bendestruktion blir synlig i röntgenbilden först när relativt stor mängd ben försvunnit. Flera tidigare studier har visat att destruktionen inte ses förrän den påverkar den kompakta yttre delen av käkbenet. Andra studier har däremot visat att destruktionen kan ses tidigaThe aim was to study digital radiography and to evaluate the influence of image processing on digital dental radiographs for the assessment of periapical lesions. In four studies, artificial bone lesions were made periapically and interradicularly in the mandibular premolar and molar regions. In a clinical study, direct digital radiographic images depicting the periapical bone tissue of different

Abstract Purpose – The purpose of this paper is to examine the way organizational actors argue to obtain a license to operate for new ventures. Design/methodology/approach – The design, which addresses the issue at the industry level, consists of a case study of the ways in which power developers argue for the development of wind energy in Sweden. Findings – The study shows that wind power develop

The European Spallation Source (ESS) linac will consist of three families of superconducting RE cavities to accelerate protons to a final beam energy of 2.5 GeV for collision with the target. Beam induced HOMs in these cavities may drive the beam unstable and increase the cryogenic load, severely limiting the operation of the linac. The effect of these modes on the beam quality is investigated in

Catalysts belonging to the Mo-V-Nb-Te-O system have been prepared with both a slurry method and hydrothermal synthesis and were tested for propane and propylene ammoxidation to acrylonitrile. All samples were characterized with BET, XRD, ICP and XPS. The catalysts were found to consist of three phases, to which activity and selectivity correlations were made. The results indicate that both an orth

In spite of the continuous development of production systems work-related musculoskeletal disorders is still a large problem. One reason might be the difficulties in quantifying the ergonomic effects of interventions. In this paper ergonomic consequences of technical and organisational changes were quantified in a plant for producing slats for parquet flooring. Muscle activity, work postures and m

To obtain full sky coverage, astronomical adaptive optics systemsrequire Na Sodium Beacons (SBs) (also referred to as Laser Guide Starsor LGSs) located at heights extending from 85 to 100 km. When viewed atthe edge of large telescopes these SBs appear elongated. For the Euro5050 meter aperture telecopes this elongation amounts to 6 to 9 arcsecondswhen the laser is launched from a point on the tele

A new version of the circuit for the readout of the ATLAS straw tube detector, TRT [1], has been developed in a deep-submicron process. The DTMROC-S is fabricated in a commercial 0.25μm CMOS IBM technology, with a library hardened by layout techniques [2]. Compared to the previous version of the chip [3] done in a 0.8μm radiation-hard CMOS and despite of the features added for improving the robust

Background and Purpose: The purpose of this study was to determine which leads in the standard 12-lead electrocardiogram (ECG) are the best for detecting acute coronary syndrome (ACS) among chest pain patients in the emergency department. Methods: Neural network classifiers were used to determine the predictive capability of individual leads and combinations of leads from 862 ECCs from chest pain

Recent studies in Drosophila have shown that heparan sulfate proteoglycans (HSPGs) are required for Wingless (Wg/Wnt) signaling. In addition, genetic and phenotypic analyses have implicated the glypican gene daily in this process. Here, we report the identification of another Drosophila glypican gene, daily-like (dly) and show that it is also involved in Wg signaling. Inhibition of dly gene activi

Purpose. The purpose of this study was to test the General Motor Function Assessment Scale (GMF) for content and criterion validity in geriatric home-rehabilitation. Furthermore, the GMF was analysed with respect to sensitivity, distribution, and for floor and ceiling effects. Method. Content validity was explored by questionnaires circulated to ten experts in the field of geriatrics. Three assess

Many large marine vertebrates are today threatened by human activities and it is therefore crucial to obtain information on their distribution and behaviour at sea. In particular little is known about the time necessary for juveniles to acquire the foraging skills of adults. We tracked 13 juvenile wandering albatrosses Diomedea exulans by satellite telemetry during their first year at sea. They co

The camera eyes of fishes and cephalopods have come forth by convergent evolution. In a variety of vertebrates capable of color vision, longitudinal chromatic aberration (LCA) of the optical system is corrected for by the exactly tuned longitudinal spherical aberration (LSA) of the crystalline lens. The LSA leads to multiple focal lengths, such that several wavelengths can be focused on the retina

Popular Abstract in Swedish Avhandlingen undersöker naturumgängets modernisering i Förenade Arabemiraten, en federation av sju shejkdömen på den arabiska sidan av Persiska Viken. De traditionella näringarna var handel, pastoralism, fiske och pärlfiske, men dessa har sedan 1960-talet ersatts av en ekonomi baserad på export av fossila bränslen. Landet har under kort tid övergått från att vara ett trThe thesis investigates human-environmental relations in the rapidly modernizing United Arab Emirates, a federation of seven Arabian Gulf sheikhdoms. Since its establishment in 1971, the UAE has been transformed from a subsistence society based mainly on pastoralism and maritime activities (fishing, pearling, and trade) into an ultramodern society, with an economy based on the export of fossil fue

A stochastic model based on a probability density function (PDF) was developed for the investigation of different conditions that determine knock in spark ignition (SI) engine, with focus on the turbulent mixing. The model used is based on a two-zone approach, where the burned and unburned gases are described as stochastic reactors. By using a stochastic ensemble to represent the PDF of the scalar
