The Iranian Light Source Facility is a fourth-generation low emittance synchrotron light source under development in Iran. The design and in-house fabrication of RF cavities are key elements of this project. The choice of 100 MHz capacity loaded RF cavities offers many advantages compared to other cavity types due to a simpler geometry, ease of fabrication, and lower costs for manufacturing and RF

In order to improve the active regenerative cooling performance of a scramjet using supercritical n-decane, a new type of cooling channel, the double-layer channel, is proposed. Based on reliable numerical simulations, temperature profiles, fluid flow track, vortex structure and buoyancy force distribution of three cases are presented, respectively. It is found that the heat transfer performance o

Objective: To compare mode of birth in Robson group 1 according to administration of oxytocin for labour augmentation. Design and participants: A retrospective review of 724 medical records from women in Robson group 1 was performed. The outcome measurements were: mode of birth in relation to presence of labour dystocia when initiating augmentation with oxytocin, duration of augmentation with oxyt

Purpose: To test the diagnostic performance of cardiovascular magnetic resonance (CMR) tissue-tracking (TT) to detect the presence of late gadolinium enhancement (LGE) in patients with a diagnosis of myocardial infarction (MI) or myocarditis (MYO), preserved left ventricular ejection fraction (LVEF) and no visual regional wall motion abnormalities (RWMA). Methods: We selected consecutive CMR studi

Strain localisation structures, such as shear fractures and compaction bands, are of importance due to their influence on permeability and therefore outgassing, a factor thought to influence eruptive style. In this study, we aim to develop a better understanding of strain localisation in porous volcanic rocks using X-ray tomographic images of samples of porous andesite (porosity = 0.26) acquired b

This thesis focuses on describing the concept of creative activities as intervention (CaI) and the occupational values experienced in doing CaI. Creative activities are frequently used as interventions in occupational therapy and are associated with subjective health and wellbeing. There is a lack of clarity in the definitions of the concept and there is no research presented regarding the experie

Methodology was developed to expand the range of benign alkyl glycoside surfactants to include also anionic types. This was demonstrated possible through conversion of the glycoside to its carboxyl derivative. Specifically, octyl β-D-glucopyranoside (OG) was oxidized to the corresponding uronic acid (octyl β-D-glucopyranoside uronic acid, OG-COOH) using the catalyst system T. versicolor laccase/2,

Chest pain is one of the most common complaints at the emergency department (ED), and it is commonly the perceived likelihood of acute coronary syndrome (ACS) that drives management. Guidelines from the European Society of Cardiology (ESC) recommend the use of a 0-/1-h high-sensitivity cardiac troponin T (hs-cTnT) protocol to rule out or in ACS, but this is mostly based on observational studies. T

The Travel Time Information System (TTIS) is an Intelligent Traffic Control System installed in Poland. As is common, travel time is the only factor in the decision about rerouting traffic, while a route recommendation may consider multiple criteria, including road safety. The aim of the paper is to analyze the safety level of the entire road network when traffic is rerouted on paths with differen

För att ta itu med den katastrof som vi i dag i Sverige bevittnar vad gäller den grova våldsbrottsligheten, borde regeringen tillsätta en nationell kriminologisk samordnare. Det skriver Ardavan Khoshnood och Sten Levander.To address the catastrophe we are witnessing in Sweden today with respect to serious violent crimes, the government should appoint a State Criminologist, writes Ardavan Khoshnood and Sten Levander.

In this study, we present a combined small-angle neutron and X-ray scattering (SANS and SAXS) study of the nanoscale structure of cortical bone specimens from three different species. The variation of the scattering cross section of elements across the periodic table is very different for neutrons and X-rays. For X-rays, it is proportional to the electron density while for neutrons it varies irreg

Introduction: Ethiopia has one of the largest number of adolescents living with HIV (ALHIV). As these adolescents reach adulthood they need to transfer from pediatric to adult-oriented clinics. Clear implementation guidelines for transition are lacking and factors associated with successful transition are inadequately investigated. Our objective was to describe the rate and age of transition from Introduction: Ethiopia has one of the largest number of adolescents living with HIV (ALHIV).
