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

We establish existence and uniqueness of solutions in the anisotropic Sobolev space H^{1,1/2} to the two dimensional Navier-Stokes equations with source data in H^{-1,-1/2}. Our results give a new elementary proof for and extend some recent results by G. Grubb.

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

Following the 2008–2009 global financial crisis, ‘green energy economy’ packages have been implemented to stimulate sustainable economic growth in several Organisation for Economic Co-operation and Development (OECD) countries. Clearly focused on the energy sector, these packages typically include energy-efficiency policy measures and aim to encourage the transition towards a low-carbon economy. W

We appraised the methodology, execution and quality of the five published meta-analyses that are based on the five randomized controlled trials (RCTs) which compared cardiotocography (CTG) +ST analysis to CTG. The meta-analyses contained errors, either created de novo in handling of original data, or from a failure to recognize essential differences among the RCTs, particularly in their inclusion

The main purpose of the recently introduced Bürger-Diehl simulation model for secondary settling tanks was to resolve spatial discretization problems when both hindered settling and the phenomena of compression and dispersion are included. Straightforward time integration unfortunately means long computational times. The next step in the development is to introduce and investigate time-integration

Objective: Osteoarthritis (OA) is a chronic and slowly progressive disease for which biomarkers may be able to provide a more rapid indication of therapeutic responses to therapy than is currently available; this could accelerate and facilitate OA drug discovery and development programs. The goal of this document is to provide a summary and guide to the application of in vitro (biochemical and oth

The aim of this study was to establish if repeated quantitative 201Tl SPET scanning during follow-up of astrocytoma therapy can provide information that is relevant for clinical management. Sixteen consecutive patients, with histopathologically verified highly malignant astrocytoma, were followed during PCV chemotherapy. Imaging with 201Tl SPET and CT was performed repeatedly over 8-16 weeks until

This essay attempts to shed light on why aggressive ideas gain support within established western states. To do that it attempts to answer the question why the armed conflict against Iraq received such varied support during the first four months of 2003 within the United States, the United Kingdom, Australia, France and Spain. A comparative study indicates that the justifications for the armed con

Through-wall imaging (TWI) is important from the point of view of rescue operations and surveillance. Several researchers have been working in this field but have still not obtained any concrete results. TWI using narrow band radar faces the problem of low resolution whereas ultra-wideband (UWB) radar provides better resolution, classification and low loss for the imaging signals. TWI faces many c

In this paper some of the numerical problems associated with computing the generalized inverse of a matrix are discussed and illustrated by a detailed analysis of an iteration of Ben-Israel and Cohen.

With data from two comparable corpora of spoken British English, the London-Lund Corpus and the new London-Lund Corpus 2, this study tracks the development of the reactive what-x construction half a century back in time. The study has two goals: (i) to describe the uses of the construction over time and (ii) to establish the motivations and mechanisms related to its development in spoken dialogue.

The phase diagram of the Al–B–C system has been calculated at pressure 7.7 GPa using models of the phenomenological thermodynamics with the interaction parameters derived from the experimental data on the phase equilibria at high pressures and temperatures.
