Objectives - Because of the rarity of small bowel adenocarcinoma (SBA), little is known about the aetiology of this disease. This study aimed to identify occupational clustering of cases SBA as a systematic approach to new hypotheses on the aetiology of this disease. Methods - A European multicentre case-control study was conducted in 1995-7, inclusive. Incident cases aged 35-69 years with SBA (n=
On-Going Change in English Modality: Emancipation Through Frequency The English modal expressions BE going to, HAVE got to, and want to are often contracted to gonna, gotta, and wanna in spoken language. These contracted forms have gained both in frequency and conventionality in recent times.In this article, I present an investigation into the status of the contractions between phonetic reduction
Extended abstractNew technologies have enabled an unprecedented level of data collection, enabling retailers to providepersonalized experiences as part of their strategy to deliver better customer value and managecustomer relationships. At the same time, increasingly intrusive data collection techniques have raisedsignificant privacy concerns among consumers and regulators. The result is an increa
The aim of this paper is to find appropriate approximate expressions of the coherent electromagnetic field scattered by a particulate slab.The exact solution of the coherent electric field to the multiple scattering problem in the slab is determined by the solution of a set of integral equations. By iterating the integral equations, an approximate solution is obtained, which approximates the solutThe aim of this paper is to find appropriate approximate expressions of thecoherent electromagnetic field scattered by a particulate slab.

Background and purpose — Computed tomography (CT) has become a valuable tool for preoperative planning and perioperative, real-time navigation during total hip arthroplasty (THA). CT can also quantify postoperative implant migration without the need for implanted bone markers, making it a promising alternative to the current gold standard radiostereometric analysis (RSA). Our aim was to evaluate t
Objective. To compare the efficacy and safety of intra-articular injections of two different hyaluronan preparations and placebo in patients with knee osteoarthritis. Methods. In a randomized, patient- and observer-blind, placebo-controlled and multicentre trial with parallel groups, 210 patients, aged 60 yr or above, with knee osteoarthritis were included in a per protocol analysis. The patients
Several disperse dyes (DDs) are still considered to be the most important allergens in textile dermatitis, but there are sparse data about their current use in textiles. The aim of this review was to evaluate published studies and reports on contact allergy to DDs published in PubMed during the last 22 years (1990-2012). Prevalence data are provided by study and by dye, as well as by the described
Helicobacter pylori was identified in human liver tissue by PCR, hybridization, and partial DNA sequencing. Liver biopsies were obtained from patients with primary sclerosing cholangitis (n = 12), primary biliary cirrhosis (n = 12), and noncholestatic liver cirrhosis (n = 13) and (as controls) normal livers (n = 10). PCR analyses were carried out using primers for the Helicobacter genus, Helicobac
Engine efficiency is often controlled in an indirectway through combustion timing control. This requires a prioriknowledge of where to phase the combustion for differentoperating points and conditions. With cylinder individual efficiencyestimation, control strategies aiming directly at fuelconsumption optimization can be developed. It has previouslybeen shown that indicated efficiency can be estim
The structure tensor is a powerful tool describing the local intensity structure of an image or image sequence. In this paper we give a model for the noise distribution of the components of the tensor. In order to do so we have also investigated some properties of the gamma distribution. We show that, given an input image corrupted with Gaussian noise, the noise in the structure tensor can be mode
Background: Imatinib causes increased turnover of stromal collagen, reduces collagen fibril diameter, enhances extracellular fluid turnover and lowers interstitial fluid pressure (IFP) in the human colonic carcinoma KAT-4/HT-29 (KAT-4) xenograft model. Methods: We compared the effects of imatinib on oxygen levels, vascular morphology and IFP in three experimental tumor models differing in their co
Purpose: The aim of this study was to develop a deep learning-based method for segmentation of bones in CT scans and test its accuracy compared to manual delineation, as a first step in the creation of an automated PET/CT-based method for quantifying skeletal tumour burden. Methods: Convolutional neural networks (CNNs) were trained to segme

Occupational exposure to toluene diisocyanate (TDI) is a known occupational hazard and the occupational exposure limits in air are very low. One of the most common methods to monitor exposure to isocyanates is to sample air through filters impregnated with 1-(2-methoxyphenyl) piperazine (2MP). In one earlier field study it was found that long-term sampling with 2MP-filters underestimated the expos
AimTo understand service users' experiences of their current mental health services and explore reflections on the Flexible Assertive Community Treatment (FACT) model and its role in future practice.MethodsA total of 17 experts participated in individual and dyadic in-depth interviews. A reflexive thematic analysis was performed on the participants' experiences of current mental health services anBackground: A person-centred and recovery-oriented approach is an integral part of modern mental health services founded on the experiential knowledge of service users. Their reflections as experts, grounded in their unique experience as service users, play a significant role in developing and improving the existing care. Experiential knowledge is therefore a means to enhance the relevance of rese
