HYPOTHESIS: The clinical and physiological features of patients with short segments of columnar-lined esophagus (CLE) with and without intestinal metaplasia (IM) are distinct.DESIGN: Retrospective case series.SETTING: University tertiary referral center.PATIENTS: Sixty-five consecutive patients with a 2-cm or shorter length of endoscopically visible CLE.INTERVENTIONS: The type of CLE and the prese
BACKGROUND: This study evaluates the efficiency and safety of two methods of chest drainage after uncomplicated oesophagectomy.METHODS: A prospective randomized study between active suction drainage and passive chest drainage was carried out in 101 patients who underwent gastric pull-up oesophagectomy.RESULTS: No difference in the prevalence of pneumothorax during treatment was noted between the a

Drop breakup in high-energy emulsification is often modelled using a population balance equation (PBE) framework. For cases with high emulsifier to disperse phase concentration, the PBE is dominated by the fragmentation term. Since there are no analytical solutions to the continuous PBE for physically reasonable fragmentation rate expressions, a discretization is often needed to evaluate the PBE,
Misstänksamheten mot det nyuppfunna margarinet var nära att leda till ett totalförbud i Sverige kring sekelskiftet 1900. Ännu idag florerar fördomar mot ”konstsmöret”, som måste betraktas som ett av våra mest politiskt kontroversiella livsmedel.

Understanding ethical buying behaviour is an important component in the study of sustainability. Multiple studies on fair trade have been conducted in established markets in Europe, with limited but increasing research in emerging markets. This study used a questionnaire survey to investigate South African consumers’ ethical buying behaviour, using conjoint analysis to imitate the multi-attribute
Radar technology has developed rapidly during the last century. Besides its initial use for military, it is nowadays also applied for many civil applications. Improvements in circuit technology make integrated radar sensors possible, allowing a significant reduction of the production cost. Integrated radio circuits in the low gigahertz range are widely available, not least driven by wireless commu
Objective: To assess the reliability of speech variables and speech-related quality indicators in the Swedish quality registry for cleft lip and palate (CLP). Design: Retrospective study. Setting: Primary care university hospitals. Participants: Fifty-two 5-year-old children with unilateral CLP and 41 with bilateral CLP. Main Outcome Measures: Registry data for “percent nonoral errors” and “percei
Lean Startup has been impacting how startups and incumbents innovate their business models. However, academic understanding of Lean Startup and the associated experimentation process is only emerging. Recent academic critique of Lean Startup by Felin and colleagues (in press) highlights the inadequate guidance provided for hypotheses generation; limits of experiential learning from customer feedba
Purpose: The abnormal deposition of tau begins before the onset of clinical symptoms and seems to target specific brain networks. The aim of this study is to identify the spatial patterns of tau deposition in cognitively normal older adults and assess whether they are related to amyloid-β (Aβ), APOE, sex, and longitudinal cognitive decline. Methods: We included 114 older adults with cross-sectiona
Background: Willfully not responding to auditory stimuli hampers accurate behavioral measurements. An objective measure of covert manual suppression recorded during response tasks may be useful to assess the veracity of responses to stimuli. Purpose: To investigate whether the lateralized readiness potential (LRP), an electrophysiological measure of corticomotor response and suppression, may be of
A substrate-free approach of semiconductor nanowire growth has been achieved by the aerotaxy technique previously. In this work, we propose an in situ method to monitor the size of nanowires through non-destructive optical-extinction measurements. Our work aims to build a theoretical look-up database of extinction spectra for a single nanowire of varying dimensions. We describe the origin of possi
Hypertrophic lichen planus (HLP) is a variant of lichen planus characterized by marked epidermal hyperplasia and severe pruritus. We present a case of a female patient with HLP and concomitant primary biliary cirrhosis, which responded to topical therapy with betamethasone under occlusion and TCA-peelings.
An overview is provided of the 15 neutron beam instruments making up the initial instrument suite of the European Spallation Source (ESS), and being made available to the neutron user community. The ESS neutron source consists of a high-power accelerator and target station, providing a unique long-pulse time structure of slow neutrons. The design considerations behind the time structure, moderator
Sterols regulate several physico-chemical properties of biological membranes that are considered to be linked to function. Ergosterol is the main sterol molecule found in the cell membranes of yeasts and other fungi. Like the cholesterol found in mammalian cells, ergosterol has been proposed to have an ordering and condensing effect on saturated phospholipid membranes. The effects of cholesterol h
