Abstract Compact spinning with pneumatic grooves is a spinning process to gather fibers by blended actions of airflow and mechanical forces. Modified from the ring spinning system, the lateral compact spinning with pneumatic grooves can improve yarn appearance and properties due to generated additional twists. In this study, we investigated additional twists of the lateral compact spinning with pneumatic grooves via a finite element (FE) method. An elastic thin rod was used to model a fiber to simulate its dynamic deformation in the three-dimensional space, and the space bar unit was used to simplify the fiber model for the dynamic analysis.… More >

Abstract The out-of-plane fold is a common defect of composite materials during the manufacturing process and will greatly affect the compressive strength as well as the service life. Making it of great importance to investigate the influence of out-of-plane defects to the compressive strength of laminate plates of composite materials, and to understand the patterns of defect evolution. Therefore, the strip method is applied in this article to create out-of-plane defects with different aspect ratios in laminated plates of composite materials, and a compressive performance test is conducted to quantify the influence of out-of-plane defects. The result shows that the compressive… More >

Abstract Background: In asymptomatic children, screening echocardiography has been used to attempt to diagnose rheumatic heart disease (RHD) at an early stage (latent RHD). World Heart Federation guidelines have standardized categorization of “definite,” “borderline,” or no RHD by echo findings. The progression of RHD diagnosed through echo screening is not known. In 2014, we screened 1450 schoolchildren in Malawi.
Objective: Our objective was to evaluate 2‐year RHD evolution among those diag‐ nosed through screening.
Methods: Two‐year follow‐up echocardiograms of those diagnosed with latent RHD were read by a primary, secondary, then third reader if there was disagreement. Progression or regression of… More >

Abstract Objective: The aims of this study were to compare the level of posttraumatic stress disorder between adults with and without congenital heart disease, and to examine the correlates of posttraumatic stress disorder (e.g., sociodemographics).
Design: Cross-sectional.
Setting: Two university-affiliated heart hospitals in Tehran, Iran.
Patients: A sample of 347 adults with congenital heart disease aged 18–64 years (52% women), and 353 adults without congenital heart disease matched by sex and age (±2 years) was recruited. Outcome Measures: The PTSD Scale: Self-report version was used to assess the diagnosis and severity of posttraumatic stress disorder. Hierarchical multivariate logistic regression analyses were… More >

Abstract In the 2017, “Cairo Accord on Rheumatic Heart Disease—From Molecules to The Global Community” experts from endemic areas enumerated an approach to reduce the population burden of rheumatic heart disease. The 10 key recommendations in‐ clude immediate logistical objectives as well as domains for further study. Echocardiographic population screening programs were relegated to research alone. Given the large body of supporting data, relegating echo screening to an investiga‐ tional modality is an opportunity lost. More >

Abstract Flashback, related to the traumatic event, is a prominent symptom of posttraumatic stress disorder (PTSD). The dual representation theory (DRT) of PTSD emphasizes that the weakened contextual representation (C-rep), the enhanced sensory representation (S-rep) and the loss of connection between C-rep and S-rep play an important role in the formation and retrieval of flashback. DRT proposes that cognitive intervention tasks which inhibit S-rep or enhance C-rep can reduce flashbacks. And many studies have proved this theoretical hypothesis. In the future, simulation intervention studies should continue to strengthen, some clinical application studies should also be appropriately carried out. Besides, future researchers… More >

Abstract In order to predict and evaluate injury mechanism and biomechanical response of the facial impact on head injury in a crash accident. With the combined modern medical imaging technologies, namely computed tomography (CT) and magnetic resonance imaging (MRI), both geometric and finite element (FE) models for human head-neck with detailed cranio-facial structure were developed. The cadaveric head impact tests were conducted to validate the headneck finite element model. The intracranial pressure, skull dynamic response and skull-brain relative displacement of the whole head-neck model were compared with experimental data. Nine typical cases of facial traffic accidents were simulated, with the individual… More >

Abstract The mechanism which is going to be made following the technical data presented in this work, represents a major step in the post-traumatic rehabilitation on the ankle articulation. The machine's support is a metallic confection of welded rectangular pipe, metallic profiles and sheet, which assures the appliance of the component parts and contains the sitting basis of the mechanism on the floor. The plaque is the element which directly sustains the person using the mechanism, and which has an oscillating movement in a vertical plane on the circumference. The plaque is turning-proof around the vertical axis of the 1^st axel,… More >

Abstract ETFE cushions are increasingly being used to form high-profile facades and structural forms. This investigation aims to extend an analytical theory of large deformation in order to predict the shape and stress distributions of an un-patterned square ETFE cushion without the need to resort to discretised numerical methods. In order to assess the validity of the theoretical procedure a prototype cushion has been analysed using a finite element simulation. The theoretical procedure is also compared with alternative approximate equations proposed for the design of ETFE cushions. More >
