Teaching Parents Read, Ask, Answer, Prompt Strategies via Telepractice: Effects on Parent Strategy Use and Child Communication
Authors: Dodge-Chin Cheri , Shigetomi-Toyama Sandra , Quinn Emily D. 
Published: January 2022

Purpose:
This study aimed to explore the feasibility of a telepractice communication partner intervention for children who use augmentative and alternative communication (AAC) and their parents.

Method:

Five children (aged 3;4–12;9 [years;months]) with severe expressive communication impairments who use AAC and their parents enrolled in a randomized, multiple-probe design across participants. A speech-language pathologist taught parents to use a least-to-most prompting procedure, Read, Ask, Answer, Prompt (RAAP), during book reading with their children. Parent instruction was provided through telepractice during an initial 60-min workshop and five advanced practice sessions (
M
= 28.41 min). The primary outcome was parents' correct use of RAAP, measured by the percentage of turns parents applied the strategies correctly. Child communication turns were a secondary, exploratory outcome.

Results:
There was a functional relation (intervention effect) between the RAAP instruction and parents' correct use of RAAP. All parents showed a large, immediate increase in the level of RAAP use with a stable, accelerating (therapeutic) trend to criterion after the intervention was applied. Increases in child communication turns were inconsistent. One child increased his communication turns. Four children demonstrated noneffects; their intervention responses overlapped with their baseline performance.

Conclusions:
Telepractice RAAP strategy instruction is a promising service delivery for communication partner training and AAC interventions. Future research should examine alternate observation and data collection and ways to limit communication partner instruction barriers.
A Survey of Speech-Language Pathology Graduate Students' Perceptions of Telepractice Pre- and Posttraining During the COVID-19 Pandemic
Authors: Hatcher Allison , Frost Kelly , Weiler Brian , Bland Lauren 
Published: January 2022

Purpose:
Many university programs in speech-language pathology that offer clinical training as part of their graduate training transitioned to a telepractice service delivery model in response to the COVID-19 pandemic. The purpose of this study was to survey speech-language pathology graduate student clinicians on their knowledge of and comfortability with telepractice before and after participation in a telepractice training program.

Method:
Graduate students in a speech-language pathology distance program participated in a remote summer clinical internship that included a 5-week telepractice training. Pre- and posttraining surveys were completed by 27 graduate students.

Results:
Results of a Wilcoxon signed-ranks test indicated that posttest telepractice knowledge question scores were significantly greater than pretest telepractice knowledge question scores. Likewise, posttest telepractice comfort question scores were significantly greater than pretest telepractice comfort question scores.

Conclusions:
These findings support the need to integrate a telepractice component to clinical education for speech-language pathology programs at the graduate level. Offering a specifically designed and hands-on telepractice training to graduate students in speech-language pathology can be an effective pedagogical piece to university degree programs.

Published: January 2022

Abstract
Background To find effective treatments for low back pain remains a major challenge in physical therapy. Numerous treatment methods currently exist, but the use of real-time visual feedback is a promising new therapeutic approach. The opportunities for its implementation and use require further research.
Objective To develop a video-supported system for visual feedback and to test its usability.
Method The prototype of a video-based system for visual feedback was developed and tested on a person with persistent unspecific lumbar back pain. The system was evaluated through an interview with the subject and the system usability scale (SUS).
Results The subject was optimistic about the system’s functionality. He was astonished to see his own back while moving, which triggered positive emotions. He also found the apparatus comfortable to wear. The system achieved a value of 77.5 out of 100 on the SUS, which represents good usability.
Conclusion By means of technical adjustments to avoid a delay in transmission and an exact positioning of the monitor, further improvements in the usability can be achieved. More research will be required to evaluate the efficacy of the developed system in the treatment of lumbar back pain.

Authors: SantAnna João Paulo Cortez , Pedrinelli André , Hernandez Arnaldo José , Fernandes Tiago Lazzaretti 
Published: January 2022

ResumoO tecido muscular esquelético possui a maior massa do corpo humano, correspondendo a 45% do peso total. As lesões musculares podem ser causadas por contusões, estiramentos ou lacerações. A atual classificação separa as lesões entre leves, moderadas e graves. Os sinais e sintomas das lesões grau I são edema e desconforto; grau II, perda de função, gap e equimose eventual; grau III, rotura completa, dor intensa e hematoma extenso. O diagnóstico pode ser confirmado por ultrassom (dinâmico e barato, porém examinador-dependente); e ressonância magnética (RM) (maior definição anatômica). A fase inicial do tratamento se resume à proteção, ao repouso, ao uso otimizado do membro afetado e crioterapia. Anti-inflamatórios não hormonais (AINHs), ultrassom terapêutico, fortalecimento e alongamento após a fase inicial e amplitudes de movimento sem dor são utilizados no tratamento clínico. Já o cirúrgico possui indicações precisas: drenagem do hematoma, reinserção e reforço musculotendíneos.
Doença de Van Neck-Odelberg — Entidade rara ou subdiagnosticada?
Authors: Moreira Mafalda , Alba Diana , Nogueira Hélder , Teixeira Sandra 
Published: January 2022

ResumoA doença de Van Neck-Odelberg (VNO) é uma osteocondrose rara, que acomete a sincondrose isquiopúbica (SIP). Esta entidade deve ser incluída no diagnóstico diferencial de crianças com claudicação na marcha, dor inguinal e limitação funcional do quadril. Imagiologicamente é caracterizada por hipertrofia assimétrica da SIP. Apresentamos o caso clínico de uma criança de 4 anos, previamente saudável, atendida no serviço de emergência devido a dor inguinal no lado esquerdo e claudicação na marcha com início no mesmo dia. Não havia história prévia de trauma ou alteração dos parâmetros inflamatórios. Foi realizada uma radiografia da bacia e ressonância magnética nuclear (RMN) que evidenciou imagem radiopaca de contornos bem definidos no ramo isquiopúbico esquerdo e edema na SIP. Com diagnóstico provável de doença de VNO, o paciente foi medicado sintomaticamente, com resolução completa ao fim de 10 dias. A claudicação na marcha é um motivo frequente de avaliação médica na população pediátrica. Até os 5 anos de idade, as causas mais comuns são sinovite transitória do quadril, artrite séptica e Doença de Legg-Calvé-Perthes. Na ausência de história de trauma ou clínica sugestiva de infeção deverá ser equacionada a hipótese de doença de VNO. Para o seu diagnóstico, é fundamental a realização de radiografia da bacia, cujo achado mais comum é uma opacificação fusiforme unilateral, no nível do ísquion, podendo ser necessária a realização de RMN. O tratamento recomendado é conservador, com recuperação sintomática em 2 semanas. O conhecimento e o diagnóstico desta entidade permitem uma abordagem direcionada e sem a carga emocional para o paciente e seus familiares que outras patologias poderiam transmitir.
Arthroscopic Bone Graft and Internal Fixation of Non-Union of the Proximal Pole of the Scaphoid: Surgical Technique and Outcomes
Authors: Ecker Jeff , Shahbaz Laiba , Kohli Sukhsimran , Breidahl William , Andrijich Courtney 
Published: January 2022

Abstract
Background Fractures of the proximal pole of the scaphoid have been associated with delayed union, non-union, and avascular necrosis. This has been attributed to avascularity of the proximal pole of the scaphoid. While proximal pole non-unions can be successfully treated using open techniques, there is little information in the literature regarding arthroscopic bone graft and internal fixation of proximal pole non-unions.
Description of Technique After insertion of a 1.2-mm radiolunate K-wire, the scaphoid non-union was arthroscopically excised, bone grafted with iliac crest cancellous bone, and internally fixed with 3 × 1.2 mm K-wires.
Patients and Methods This is a retrospective study of patients who had arthroscopic bone graft of non-union of the proximal pole of the scaphoid between 2009 and 2021.
Results There were 30 cases in this study; 29 cases united. The one case that did not unite was caused by inadequate fixation of the proximal pole. The size of the proximal pole did not influence the outcome.
Conclusion Arthroscopic bone graft and internal fixation is a reliable technique for the treatment of non-union of the proximal pole of the scaphoid.
Volar Lunate Facet Fractures of the Distal Radius: Fracture Mapping Using 3D CT Scans
Authors: Clarnette Jock , De Silva April , Eardley-Harris Nathan , MacLean Simon , Bain Gregory I. 
Published: January 2022

Abstract
Background Fractures of the distal radius involving the lunate facet at the volar articular surface are unstable injuries and are usually managed operatively. Management of these fractures is challenging as our understanding of the exact fracture characteristics and associated injuries to the carpus is poor.
Purpose This study aims to define the anatomy and associated injuries of lunate facet fractures using three-dimensional computed tomography (CT) scans and fracture mapping techniques.
Methods A consecutive series of CT wrists was analyzed to identify intra-articular fractures involving the lunate facet at the volar distal radius. Fractures were mapped onto standardized templates of the distal radius using previously described fracture mapping techniques. We also identified instabilities of the carpus including volar carpal translation, ulnar translocation, scapholunate diastasis, and distal radioulnar joint (DRUJ) instability.
Results We present 23 lunate facet fractures of the distal radius. The lunate facet fragment displaces in a volar and proximal direction and the lunate always articulates with the displaced fragment. The smaller fragments displace a greater amount, in a volar direction, with pronation. The fracture tends to occur between the origin of the short and long radiolunate ligaments.
Conclusion Lunate facet fractures are frequently comprised of osteoligamentous units of the distal radius involving the short and long radiolunate ligaments and the radioscaphocapitate ligament. Assessment and management of volar carpal subluxation, scapholunate instability, ulnar translocation, and DRUJ instability should be considered.
Clinical relevance Our mapping of these fractures contributes to our understanding of the anatomy and associated instabilities and will aid in surgical planning and decision making.

Published: January 2022

Abstract
Timepix3 pixel detectors have demonstrated great potential for tracking applications. With 256 × 256 pixels, 55 µm pitch and improved resolution in time (1.56 ns) and energy (2 keV at 60 keV), they have become powerful instruments for characterization of unknown radiation fields. A crucial pre-processing step for such analysis is the determination of particle trajectories in 3D space from individual tracks. This study presents a comprehensive comparison of regression methods that tackle this task under the assumption of track linearity. The proposed methods were first evaluated on a simulation and assessed by their accuracy and computational time. Selected methods were then validated with a real-world dataset, which was measured in a well-known radiation field. Finally, the presented methods were applied to experimental data from the Large Hadron Collider. The best-performing methods achieved a mean absolute error of 1.99° and 3.90° in incidence angle θ and azimuth φ, respectively. The fastest presented method required a mean computational time of 0.02 ps per track. For all experimental applications, we present angular maps and stopping power spectra.
Simulations of geometric aspects for ARAPUCA designs
Authors: Adames M.R. 
Published: January 2022

Abstract
The photon detection system of DUNE Far Detector (FD) is based on ARAPUCA technology. The new version of ARAPUCA, named X-ARAPUCA, will be used in the first and second modules. As the second module is based on vertical drift, the design of the X-ARAPUCA needed to be changed and simulation studies are fundamental for the optimization of the device. This work presents the simulation studies of the design, size, shape, and SiPM positioning inside the reflective cavity. We designed a Python module that creates the geometry for the simulations based on given parameters such as size of the detector, numbers of SiPM and others. The physics of photons inside the X-ARAPUCA is simulated by a ray-tracer written in C++ using an uniform grid as acceleration structure. Our simulations focus on reflections and refractions using Snell’s law on the interfaces and the total internal reflections inside the wavelength shifting plate, that absorbs every incoming photon and re-emits them in a random direction. The simulation shows that the highest efficiency is reached for thin X-ARAPUCA with a square shape. Better efficiency is obtained for larger modules if one considers the number of SiPM per cm2 of the active collection area. Rectangular modules are more efficient when the SiPMs are positioned on the short side.

The Italian Association for Stress Analysis (AIAS) was founded in 1971 by researchers from academia, research centers and industry. AIAS was intended as a community where to discuss, to share and to develop scientific knowledge related to all technical aspects of stress analysis. In the years, from an initial focus on experimental techniques, AIAS contributed considerably to the development of modern numerical methods and computational techniques for the mechanical engineering design. In 2015, AIAS turned in the Italian Scientific Society of Mechanical Engineering Design.
Today, AIAS is an institutional partner that supports the instances from academia in subject area of the mechanical engineering design. Every year, AIAS organizes a technical conference offering the possibility to present research updates, share new ideas and foster collaborations. The AIAS conference has become a fundamental event for all those interested in current developments in mechanical engineering design and stress analysis, where to meet researchers, testing equipment and software developers.
The 50th AIAS Conference edition was initially re-scheduled to be held in Genoa, Italy after it was switched as virtual conference in 2020 due to COVID-19 emergency. Unfortunately, due to the continuing pandemic emergency, it was decided to go virtual again to keep continuity with the tradition, confident that, despite the difficulties of the moment, united we stand.
As for the previous year, the response of researchers and students has been outstanding: over 180 oral contribution have been presented in synchronous, during the three days of the conference, with three simultaneous parallel sessions. In addition to the thematic sessions on AIAS traditional subjects, special sessions on additive manufacturing, energetic methods for structural analysis and smart materials and MEMS have been successfully organized with the contribution of the AIAS technical committees.
Among all contributions presented at the conference, 54 have been selected to be published after peer review, in this volume. This was made possible thanks to the active participation of all AIAS members, to the work of the AIAS Scientific Committee and Conference Papers Review panel (Profs Giovanni Meneghetti, AIAS Scientific Coordinator, Luciano Afferrante, Francesco Bucchi, Filippo Cianetti, Enrico Armentani, Marco Sasso). Their outstanding contribution is gratefully acknowledged.

Effect of process parameters on the mechanical properties of a Titanium alloy fabricated by Electron Beam Melting (EBM)
Authors: Mirone G , Barbagallo R , Di Bella S 
Published: January 2022

Abstract
Electron Beam Melting is a layer-by-layer additive manufacturing technique which proved to be very efficient and versatile in the fabrication of medical devices and automotive or aerospace components. Due to the highly innovative character of the technology, its potential is not yet fully exploited and a comprehensive understanding of how the different processing parameters may affect the mechanical performance of the resulting materials still deserves to be achieved. Tensile tests on a Titanium alloy (Ti-6Al-4V-ELI) are ran at static rates for investigating the effects of different fabrication parameters on the material response, namely the speed function, the line offset, the focus offset, the number of contours and the horizontal-vertical growing direction of the specimens. A combination of such parameters is identified as a “process setup” and different setups are adopted for producing corresponding series of specimens, machined after fabrication according to ASTM F2924 and ASTM E8 regulations. The experimental procedure relies on enhanced true stress-true strain data based on the optical measurement of the neck cross section of the specimen, as an alternative to the traditional elongation-based approach to the true stress-true strain evaluation. This approach allows to better highlight the effects of the different process setups on the material performance, by focusing on the most stressed/strained material points within the overall specimen volume. The true curves allow to relate the material performance in terms of both strength and ductility to each process setup, allowing to outline the influence of single/combined fabrication parameters on the two above performance indicators.
Fracture mechanics of additive manufactured crack-like notches by digital image correlation
Authors: Minak Giangiacomo , Drvar Nenad 
Published: January 2022

Abstract
The rapid development of a variety of Additive Manufacturing (AM) techniques is witnessed by the large interest of the scientific community. Among the numerous new features offered by these techniques, very lately the possibility of including cracks of any shape, direction, and position inside AM samples to validate FEM models was explored. Therefore, the necessity arose of full-field measurement techniques that would allow the evaluation of the fracture mechanics parameters in the cases of both linear elastic and partially plastic materials, as a function of the fracture modes. Invented in the ’80 of the XX century, the Digital Image Correlation (DIC) in recent years has taken place in nearly every laboratory. It is used to measure displacements, and by numerical differentiation or coupling with Finite Element Method, to calculate strains at different spatial scales. In particular, two procedures that were successfully employed on a specific kind of specimens, based on DIC at a small scale near the crack-tip, in this paper are shown in detail.
Combined experimental methods to assess the fatigue limit
Authors: Fargione G , Giudice F , Barbagallo R , Corallo D , La Rosa G 
Published: January 2022

AbstractPurpose of this paper is to perform an energetic analysis on metal specimens under fatigue testing using the simultaneous application of different non-destructive techniques: thermography (TH), acoustic emission (AE) and digital image correlation (DIC). They assure the better evaluation, being contactless methods, usable in real time and, even if TH and DIC are related to the specimen surface, representative of the inside state of the materials. In particular, the cascade of hits and the acoustic energy were recorded to assess the parameters linked to the fracture of the materials. At the same time, the surface temperature, detected by a thermocamera, and the displacements induced on the specimen, using the DIC on the free zone of the specimens, were recorded. The DIC analysis allows the evaluation of the correct displacement by a pattern realized on the opposite face respect to TH. AE data and hysteresis curves (derived by DIC) were compared with the measures acquired by TH and reveal a reliable correlation between them in terms of fatigue limit.
Analysis of fracture behaviour in active materials for lithium ion batteries

Published: January 2022

Abstract
Several strong points make lithium ion battery one of the most widespread energy storage system. Nevertheless, one of the biggest drawbacks is the progressive damage which affects active materials, and influences cycle life as well. The hosting process of lithium ions causes the rise of mechanical stress in active material, which ultimately leads to the propagation of micro-flaws already present in fresh material. Finally, the damage of active material and solid-electrolyte interphase growth caused by cracks propagation result in capacity drop. The distribution of Mode I stress intensity factor is calculated along the semi-elliptical crack front on the outer surface and in the core of a three-dimensional spherical active material particle. A 3D and 2D finite element method analysis is performed in ANSYS Mechanical APDL starting from the mechanical stress state in active material computed with the electrochemical-mechanical model presented in previous works. The model is built using collapsed singular elements along the crack front, the not-singular version of these elements is used to model the outlying region of the crack area. The dependence of stress intensity factor on geometry size is deepened to evaluate the most critical condition. Moreover, the influence of current rate on stress intensity factor is investigated, in order to identify a current threshold beyond stress intensity factor is greater than the toughness of active material, and cracks start to propagate.
