Sulfated complex metal oxides solid acids with dual Brønsted-Lewis acidic property for production of 5-ethoxymethylfurfural from biomass-derived carbohydrates

The transformation of aldose-based carbohydrates into 5-ethoxymethylfurfural (EMF) is very challenging as compared to ketose-based carbohydrates, but the formers are more abundant and cheaper. Here, a series of sulfated complex metal oxides were synthesized for the conversion of aldose-based mono-, di-, and poly-saccharides, as well as starchy food waste into EMF. The catalysts were carefully char

Parametric study for electrode microstructure influence on SOFC performance

A solid oxide fuel cell (SOFC) is a clean and high-efficiency energy conversion device, which undergoes improvement of performance continuously. The transport of gas species and charges proceed in the porous electrodes. The porous electrodes are also responsible for the removal of exhaust gases. In this paper, a fully coupled 3D single-channel multiphysics computational fluid dynamics (CFD) model

Advanced fiber tracking in early acquired brain injury causing cerebral palsy

Background and Purpose: Diffusion-weighted MR imaging and fiber tractography can be used to investigate alterations in white matter tracts in patients with early acquired brain lesions and cerebral palsy. Most existing studies have used diffusion tensor tractography, which is limited in areas of complex fiber structures or pathologic processes. We explored a combined normalization and probabilisti

Hormonal male contraception

The demand for availability of efficient and safe contraceptive methods is strengthened by the predic-tions made by the United Nations regarding the future growth of the human population. So far, women are not only the main victims of the unsafe procedures related to terminating unwished pregnancies but do also carry the main responsibility for family planning. There is a significant desire among

Experimental study on film cooling performance of a turbine blade tip with a trapezoidal slot cooling scheme in transonic flow using PSP technique

A turbine blade tip with a trapezoidal slot cooling scheme is first proposed in the current paper. The film cooling characteristics of a turbine blade tip with a trapezoidal slot scheme are experimentally studied by the pressure sensitive paint (PSP) technique in transonic flow. Varieties of density ratio, tip clearance gap and position of the trapezoidal slot scheme are selected as investigation

Search for bottom-squark pair production in pp collision events at s =13 TeV with hadronically decaying τ -leptons, b -jets, and missing transverse momentum using the ATLAS detector

A search for pair production of bottom squarks in events with hadronically decaying τ-leptons, b-tagged jets, and large missing transverse momentum is presented. The analyzed dataset is based on proton-proton collisions at √s=13 TeV delivered by the Large Hadron Collider and recorded by the ATLAS detector from 2015 to 2018, and corresponds to an integrated luminosity of 139 fb−1. The observed data

Hip prosthetic loosening : A very personal review

Hip prosthetic loosening is often difficult to detect at an early stage, and there has been uncertainty for a long time as to when the loosening occurs and thus to the basic causes. By comparing different diagnostic methods, we found that loosening is best defined as prosthetic migration and measured by radiostereometric analysis. Convincing evidence indicates that poor interlock, poor bone qualit

“You Should Just Keep Your Mouth Shut and Do As We Say” : Forensic Psychiatric Inpatients’ Experiences of Risk Assessments

This study presents findings of forensic inpatients’ experiences of their role in the risk assessment process. Eleven patients, recruited from two forensic psychiatric clinics in Sweden, participated in semi-structured interviews which were analyzed using qualitative content analysis. The analysis of their experiences resulted in the information of three categories: Taking responsibility for one’s

A cost model for determining an optimal automation level in discrete batch manufacturing

An economic model for determining the optimal automation level for discrete batch manufacturing is presented. The model describes how the costs of parts varies between manufacturing systems of different types at differing automation levels, the part costs often being highly dependent upon the automation level selected. The optimal automation level in a given case can be determined using a relative

The Adoption of Additive Manufacturing Technology in Sweden

This paper analyzes the adoption of Additive Manufacturing (AM) technologies in Sweden. The dataset consists of a recent and representative sample of Swedish AM users (companies, universities, and research institutes). The authors investigate two questions. Firstly, what are the current applications of AM in Sweden (e.g. Rapid Prototyping (RP), production)? Secondly, what are the factors that can

Comparison of posterior hyaloid assessment using preoperative optical coherence tomography and intraoperative triamcinolone acetonide staining during vitrectomy

Purpose: To compare the specificity of diagnosing posterior vitreous detachment (PVD) using preoperative optical coherence tomography (OCT) versus intraoperative triamcinolone acetonide (TA) staining in patients undergoing vitrectomy. Patients and Methods: This retrospective cohort study included patients undergoing pars plana vitrectomy for diverse retinal pathologies. Intraoperatively, surgeons

Clinical interpretation and cutoff scores for manual ability measured by the ABILHAND questionnaire in people with stroke

Background: The ABILHAND questionnaire is recommended to assess perceived manual ability after stroke; however, more knowledge on interpretability is needed to improve the clinical applicability. Objectives: To determine clinically meaningful cutoff scores for different levels of perceived manual ability, assessed by ABILHAND, corresponding to established observed and perceived upper extremity ass
