This injury is common in athletes practicing sports that requires throwing or those who receive traumatic impacts on the shoulder area. This paper determines the biomechanical behavior of soft tissues of the glenohumeral joint when type II SLAP lesion is present. This pathology is characterized for a tear in the superior labrum which is simulated in a 3D model of the shoulder joint. A 3D model of the glenohumeral joint was obtained using the free software Slice. Then, a Finite Element analysis was done using a general purpose software which simulates a compression test with external rotation. First, a validation was done assuming a healthy joint shoulder with a previous study. Once the initial model was validated, a lesion of the labrum built using a CAD software and the same test was done again. The results obtained were stress and strain distribution of the synovial capsule and the injured labrum. ANOVA was done for the healthy and injured glenohumeral joint finding significant differences between them. This study will help orthopedic surgeons to know the biomechanics involving this type of lesion and also the other surrounding structures affected by loading the injured joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title="biomechanics">biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20model" title=" computational model"> computational model</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title=" finite elements"> finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=glenohumeral%20joint" title=" glenohumeral joint"> glenohumeral joint</a>, <a href="https://publications.waset.org/abstracts/search?q=superior%20labral%20anterior%20to%20posterior%20lesion" title=" superior labral anterior to posterior lesion"> superior labral anterior to posterior lesion</a> </p> <a href="https://publications.waset.org/abstracts/84864/biomechanical-study-of-a-type-ii-superior-labral-anterior-to-posterior-lesion-in-the-glenohumeral-joint-using-finite-element-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84864.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">208</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1087</span> Influence of Glenohumeral Joint Approximation Technique on the Cardiovascular System in the Acute Phase after Stroke</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iva%20Hereitova">Iva Hereitova</a>, <a href="https://publications.waset.org/abstracts/search?q=Miroslav%20Svatek"> Miroslav Svatek</a>, <a href="https://publications.waset.org/abstracts/search?q=Vit%20Novacek"> Vit Novacek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Aim: Autonomic imbalance is one of the complications for immobilized patients in the acute stage after a stroke. The predominance of sympathetic activity significantly increases cardiac activity. The technique of glenohumeral joint approximation may contribute in a non-pharmacological way to the regulation of blood pressure and heart rate in patients in this risk group. The aim of the study was to evaluate the effect of glenohumeral joint approximation on the change in heart rate and blood pressure in immobilized patients in the acute phase after a stroke. Methods: The experimental study bilaterally evaluated heart rate, systolic and diastolic pressure values before and after glenohumeral joint approximation in 40 immobilized participants (72.6 ± 10.2 years) in the acute phase after stroke. The experimental group was compared with 40 healthy participants in the control group (68.6 ± 14.2 years). An SpO2 vital signs monitor and a validated Microlife WatchBP Office blood pressure monitor were used for evaluation. Statistical processing and evaluation were performed in MATLAB R2019 (The Math Works®, Inc., Natick, MA, USA). Results: Approximation of the glenohumeral joint resulted in a statistically significant decrease in systolic and diastolic pressure. An average decrease in systolic pressure for individual groups ranged from 8.2 to 11.3 mmHg (p <0.001). For diastolic pressure, the average decrease ranged from 5.0 - 14.2 mmHg (p <0.001). There was a statistically significant reduction in heart rate (p <0.01) only in patients after ischemic stroke in the inferior cerebral artery. There was the average decrease in heart rate of 3.9 beats per minute (median 4 beats per minute). Conclusion: Approximation of the glenohumeral joint leads to a statistically significant decrease in systolic and diastolic pressure in immobilized patients in the acute phase after stroke. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aproximation%20technique" title="Aproximation technique">Aproximation technique</a>, <a href="https://publications.waset.org/abstracts/search?q=Cardiovaskular%20system" title=" Cardiovaskular system"> Cardiovaskular system</a>, <a href="https://publications.waset.org/abstracts/search?q=Glenohumeral%20joint" title=" Glenohumeral joint"> Glenohumeral joint</a>, <a href="https://publications.waset.org/abstracts/search?q=Stroke" title=" Stroke"> Stroke</a> </p> <a href="https://publications.waset.org/abstracts/132299/influence-of-glenohumeral-joint-approximation-technique-on-the-cardiovascular-system-in-the-acute-phase-after-stroke" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132299.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1086</span> Identification and Management of Septic Arthritis of the Untouched Glenohumeral Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumit%20Kanwar">Sumit Kanwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Manisha%20Chand"> Manisha Chand</a>, <a href="https://publications.waset.org/abstracts/search?q=Gregory%20Gilot"> Gregory Gilot</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Septic arthritis of the shoulder has infrequently been discussed. Focus on infection of the untouched shoulder has not heretofore been described. We present four patients with glenohumeral septic arthritis. Methods: Case 1: A 59 year old male with left shoulder pain in the anterior, posterior and superior aspects. Case 2: A 60 year old male with fever, chills, and generalized muscle aches. Case 3: A 70 year old male with right shoulder pain about the anterior and posterior aspects. Case 4: A 55 year old male with global right shoulder pain, swelling, and limited ROM. Results: In case 1, the left shoulder was affected. Physical examination, swelling was notable, there was global tenderness with a painful range of motion (ROM). The lab values indicated an erythrocyte sedimentation rate (ESR) of 96, and a C-reactive protein (CRP) of 304.30. Imaging studies were performed and MRI indicated a high suspicion for an abscess with osteomyelitis of the humeral head. Our second case’s left arm was affected. He had swelling, global tenderness and painful ROM. His ESR was 38, CRP was 14.9. X-ray showed severe arthritis. Case 3 differed with the right arm being affected. Again, global tenderness and painful ROM was observed. His ESR was 94, and CRP was 10.6. X-ray displayed an eroded glenoid space. Our fourth case’s right shoulder was affected. He had global tenderness and painful, limited ROM. ESR was 108 and CRP was 2.4. X-ray was non-significant. Discussion: Monoarticular septic arthritis of the virgin glenohumeral joint is seldom diagnosed in clinical practice. Common denominators include elevated ESR, painful, limited ROM, and involvement of the dominant arm. The male population is more frequently affected with an average age of 57. Septic arthritis is managed with incision and drainage or needle aspiration of synovial fluid supplemented with 3-6 weeks of intravenous antibiotics. Due to better irrigation and joint visualization, arthroscopy is preferred. Open surgical drainage may be indicated if the above methods fail. Conclusion: If a middle-aged male presents with vague anterior or posterior shoulder pain, elevated inflammatory markers and a low grade fever, an x-ray should be performed. If this displays degenerative joint disease, the complete further workup with advanced imaging, such as an MRI, CT scan, or an ultrasound. If these imaging modalities display anterior space joint effusion with soft tissue involvement, we can suspect septic arthritis of the untouched glenohumeral joint and surgery is indicated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glenohumeral%20joint" title="glenohumeral joint">glenohumeral joint</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a>, <a href="https://publications.waset.org/abstracts/search?q=infection" title=" infection"> infection</a>, <a href="https://publications.waset.org/abstracts/search?q=septic%20arthritis" title=" septic arthritis"> septic arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=shoulder" title=" shoulder"> shoulder</a> </p> <a href="https://publications.waset.org/abstracts/61211/identification-and-management-of-septic-arthritis-of-the-untouched-glenohumeral-joint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61211.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">422</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1085</span> Biomechanical Performance of the Synovial Capsule of the Glenohumeral Joint with a BANKART Lesion through Finite Element Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duvert%20A.%20Puentes%20T.">Duvert A.

Villegas </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mechanical Computation is a great tool to study the performance of complex models. An example of it is the study of the human body structure. This paper took advantage of different types of software to make a 3D model of the glenohumeral joint and apply a finite element analysis. The main objective was to study the change in the biomechanical properties of the joint when it presents an injury. Specifically, a BANKART lesion, which consists in the detachment of the anteroinferior labrum from the glenoid. Stress and strain distribution of the soft tissues were the focus of this study. First, a 3D model was made of a joint without any pathology, as a control sample, using segmentation software for the bones with the support of medical imagery and a cadaveric model to represent the soft tissue. The joint was built to simulate a compression and external rotation test using CAD to prepare the model in the adequate position. When the healthy model was finished, it was submitted to a finite element analysis and the results were validated with experimental model data. With the validated model, it was sensitized to obtain the best mesh measurement. Finally, the geometry of the 3D model was changed to imitate a BANKART lesion. Then, the contact zone of the glenoid with the labrum was slightly separated simulating a tissue detachment. With this new geometry, the finite element analysis was applied again, and the results were compared with the control sample created initially. With the data gathered, this study can be used to improve understanding of the labrum tears. Nevertheless, it is important to remember that the computational analysis are approximations and the initial data was taken from an in vitro assay. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title="biomechanics">biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20model" title=" computational model"> computational model</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20elements" title=" finite elements"> finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=glenohumeral%20joint" title=" glenohumeral joint"> glenohumeral joint</a>, <a href="https://publications.waset.org/abstracts/search?q=bankart%20lesion" title=" bankart lesion"> bankart lesion</a>, <a href="https://publications.waset.org/abstracts/search?q=labrum" title=" labrum"> labrum</a> </p> <a href="https://publications.waset.org/abstracts/93479/biomechanical-performance-of-the-synovial-capsule-of-the-glenohumeral-joint-with-a-bankart-lesion-through-finite-element-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93479.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1084</span> Operative Technique of Glenoid Anteversion Osteotomy and Soft Tissue Rebalancing for Brachial Plexus Birth Palsy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Zaidman">Michael Zaidman</a>, <a href="https://publications.waset.org/abstracts/search?q=Naum%20Simanovsky"> Naum Simanovsky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The most of brachial birth palsies are transient.

The prevalence of massive rotator cuff tears varies in some studies from 10% to 40%. Of irreparable rotator cuff tears (IRCTs), which are mostly associated with massive tear size, 79% are estimated to have recurrent tears after surgical repair. Recent studies have shown that superior capsule reconstruction (SCR) in massive rotator cuff tears can be an efficient technique with optimistic clinical scores and preservation of stable glenohumeral stability. Superior capsule reconstruction techniques most commonly use either fascia lata autograft or dermal allograft, both of which have their own benefits and drawbacks (such as the potential for donor site issues, allergic reactions, and high cost). We propose a simple technique for superior capsule reconstruction that involves using the long head of the biceps tendon as a local autograft; therefore, the comorbidities related to graft harvesting are eliminated. The long head of the biceps tendon proximal portion is relocated to the footprint and secured as the SCR, serving to both stabilize the glenohumeral joint and maintain vascular supply to aid healing. Objective: The purpose of this study is to assess the clinical outcomes of patients with large to massive RCTs treated by SCR using LHBT. Materials and methods: A study was performed of consecutive patients with large to massive RCTs who were treated by SCR using LHBT between January 2022 and December 2022. We use one double-loaded suture anchor to secure the long head of the biceps to the middle of the footprint. Two more anchors are used to repair the rotator cuff using a single-row technique, which is placed anteriorly and posteriorly on the lateral side of the previously transposed LHBT. Results: The 3 men and 5 women had an average age of 61.25 years (range 48 to 76 years) at the time of surgery. The average follow-up was 8.2 months (6 to 10 months) after surgery. The average preoperative ASES was 45.8, and the average postoperative ASES was 85.83. The average postoperative UCLA score was 29.12. VAS score was improved from 5.9 to 1.12. The mean preoperative ROM of forward flexion and external rotation of the shoulder was 720 ± 160 and 280 ± 80, respectively. The mean postoperative ROM of forward flexion and external rotation were 1310 ± 220 and 630 ± 60, respectively. There were no cases of progression of osteoarthritis or rotator cuff muscle atrophy. Conclusion: SCR using LHBT is considered a treatment option for patients with large or massive RC tears. It can restore superior glenohumeral stability and function of the shoulder joint and can be an effective procedure for selected patients, helping to avoid progression to cuff tear arthropathy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=superior%20capsule%20reconstruction" title="superior capsule reconstruction">superior capsule reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20or%20massive%20rotator%20cuff%20tears" title=" large or massive rotator cuff tears"> large or massive rotator cuff tears</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20long%20head%20of%20the%20biceps" title=" the long head of the biceps"> the long head of the biceps</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilize%20the%20glenohumeral%20joint" title=" stabilize the glenohumeral joint"> stabilize the glenohumeral joint</a> </p> <a href="https://publications.waset.org/abstracts/163250/arthroscopic-superior-capsular-reconstruction-using-the-long-head-of-the-biceps-tendon-lhbt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163250.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1082</span> Computer Aided Shoulder Prosthesis Design and Manufacturing </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Didem%20Venus%20Yildiz">Didem Venus Yildiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Hocaoglu"> Murat Hocaoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Dursun"> Murat Dursun</a>, <a href="https://publications.waset.org/abstracts/search?q=Taner%20Akkan"> Taner Akkan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shoulder joint is a more complex structure than the hip or knee joints. In addition to the overall complexity of the shoulder joint, two different factors influence the insufficient outcome of shoulder replacement: the shoulder prosthesis design is far from fully developed and it is difficult to place these shoulder prosthesis due to shoulder anatomy. The glenohumeral joint is the most complex joint of the human shoulder. There are various treatments for shoulder failures such as total shoulder arthroplasty, reverse total shoulder arthroplasty. Due to its reverse design than normal shoulder anatomy, reverse total shoulder arthroplasty has different physiological and biomechanical properties. Post-operative achievement of this arthroplasty is depend on improved design of reverse total shoulder prosthesis. Designation achievement can be increased by several biomechanical and computational analysis. In this study, data of human both shoulders with right side fracture was collected by 3D Computer Tomography (CT) machine in dicom format. This data transferred to 3D medical image processing software (Mimics Materilise, Leuven, Belgium) to reconstruct patient’s left and right shoulders’ bones geometry. Provided 3D geometry model of the fractured shoulder was used to constitute of reverse total shoulder prosthesis by 3-matic software. Finite element (FE) analysis was conducted for comparison of intact shoulder and prosthetic shoulder in terms of stress distribution and displacements. Body weight physiological reaction force of 800 N loads was applied. Resultant values of FE analysis was compared for both shoulders. The analysis of the performance of the reverse shoulder prosthesis could enhance the knowledge of the prosthetic design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reverse%20shoulder%20prosthesis" title="reverse shoulder prosthesis">reverse shoulder prosthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title=" 3D printing"> 3D printing</a> </p> <a href="https://publications.waset.org/abstracts/116132/computer-aided-shoulder-prosthesis-design-and-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116132.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1081</span> Computational Models for Accurate Estimation of Joint Forces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Elnour%20Abdelrahman%20Eltayeb">Ibrahim Elnour Abdelrahman Eltayeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational modelling is a method used to investigate joint forces during a movement.

It make an uncomfortable sensation which disturbance daily activity. The studies of frozen shoulder are still limited. This study used a true experimental pre and post test design with a group design. The participant underwent dextrose prolotherapy injection in the rotator cuff, intraarticular glenohumeral joint, long head tendon biceps, and acromioclavicular joint injections with 15% dextrose, respectively, at week 2, week 4, and week 6. Participants were followed for 12 weeks. The specific biomarker MMP and TIMP, ROM, DASH score were measured at baseline, at week 6, and week 12. The data were analyzed by multivariate analysis (repeated measurement ANOVA, Paired T-Test, and Wilcoxon) to determine the effect of the intervention. The result showed a significant decrease in The Disability of the Arm, Shoulder, and Hand (DASH) score in prolo injection patients in each measurement week (p < 0.05). While the measurement of Range of Motion (ROM), each direction of shoulder motion showed a significant difference in average each week, from week 0 to week 6 (p <0.05).Dextrose prolotherapy injection results give a significant improvement in functional outcome of the shoulder joint, and ROMand did not show significant results in assessing the specific biomarker, MMP-1, and TIMP-1 in tissue repair. This study suggestion an alternative to the use of injection prolotherapy in Frozen shoulder patients, which has fewer side effects and better effectiveness than the use of corticosteroid injections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frozen%20shoulder" title="frozen shoulder">frozen shoulder</a>, <a href="https://publications.waset.org/abstracts/search?q=ROM" title=" ROM"> ROM</a>, <a href="https://publications.waset.org/abstracts/search?q=DASH%20score" title=" DASH score"> DASH score</a>, <a href="https://publications.waset.org/abstracts/search?q=prolotherapy" title=" prolotherapy"> prolotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=MMP-1" title=" MMP-1"> MMP-1</a>, <a href="https://publications.waset.org/abstracts/search?q=TIMP-1" title=" TIMP-1"> TIMP-1</a> </p> <a href="https://publications.waset.org/abstracts/150215/specific-biomarker-level-and-function-outcome-changes-in-treatment-of-patients-with-frozen-shoulder-using-dextrose-prolotherapy-injection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150215.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">113</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1079</span> Design Modification of Lap Joint of Fiber Metal Laminates (CARALL)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaher%20Bano">Shaher Bano</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20Fida"> Samia Fida</a>, <a href="https://publications.waset.org/abstracts/search?q=Asif%20Israr"> Asif Israr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The synergistic effect of properties of metals and fibers reinforced laminates has diverted attention of the world towards use of robust composite materials known as fiber-metal laminates in many high performance applications.

In many Western countries, an increasing of children with separated parents have joint physical custody, which is believed to be in the best interests of the child, as children can maintain personal relations and direct contact with both parents on a regular basis. The aim of the article is to examine joint physical custody, both from the perspective of the binding legal instruments that are relevant to joint physical custody, the Principles of European Family Law drafted by the CEFL, as well as the international research on this matter. The thesis underlying this paper is that joint physical custody is in itself neither good nor bad, and it depends on how the arrangements are managed by the parents. The paper includes a reflection on joint physical custody in the face of the COVID-19 crisis. The results indicate that in normal circumstances, joint physical custody demands broad communication, and now it times of crisis, we need over-communication about children and plans. Only a very tight and coordinated co-parenting plan make the whole family safer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20physical%20custody" title="joint physical custody">joint physical custody</a>, <a href="https://publications.waset.org/abstracts/search?q=co-parenting" title=" co-parenting"> co-parenting</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20welfare" title=" child welfare"> child welfare</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a> </p> <a href="https://publications.waset.org/abstracts/144611/joint-physical-custody-lessons-from-the-european-union" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144611.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1077</span> Seismic Response Analysis of Frame Structures Based on Super Joint Element Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Xu">Li Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Hong"> Yang Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20Zhao%20Wen"> T.

However, rigid joint assumption has been generally used in the seismic response analysis of RC frames, in which two kinds of inelastic deformation of joint have been ignored. Based on OpenSees platform, ‘Super Joint Element Model’ with more detailed inelastic mechanism is used to simulate the inelastic response of joints. Two finite element models of typical RC plane frame, namely considering or ignoring the inelastic deformation of joint respectively, were established and analyzed under seven strong earthquake waves. The simulated global and local inelastic deformations of the RC plane frame is shown and discussed.

During heel strike, a huge amount of energy is transmitted through the leg towards knee joint, which in fact is damped at heel and leg muscles. During high shocks, although it is damped to a certain extent, the balance force transmits towards knee joint which could damage the knee. Due to the vital function of the knee joint, it should be protected against damage due to additional load acting on it. This work concentrates on the development of spring mass damper system which exactly replicates the stiffness at the heel and muscles and the objective function is optimized to minimize the force acting at the knee joint.

In a joint physical custody arrangement, the child spends substantial, but not necessarily equal, time with both parents. Joint physical custody can be symmetric care arrangement or not. However, it is accepted in the jurisprudence that the best interests of the child is served when the child spends at least 35% of the time during a two-week period with each parent. Joint physical custody, also known as joint, dual, or shared residence, is a challenge in contemporary family law. It has its supporters and opponents. On the one hand, joint physical custody is beneficial because it provides children with frequent and continuous contact with a mother and father after their divorce or separation. On the other hand, it isn’t good for children to be shuttled back and forth between two residences. Children need a home base. The conclusion is therefore that joint physical custody can’t be seen as a panacea for all post-divorce or post-separation parenting cases and the court shouldn’t automatically make such a determination. The possibility to award this arrangement requires the court to carefully weigh the pros and cons of each individual case. It is difficult to say that joint physical custody is better than single physical custody in any case. It depends on the circumstances and needs of each family. It appears that an individual approach is going to be much better as opposed to a one-size-fits-all idea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20physical%20custody" title="joint physical custody">joint physical custody</a>, <a href="https://publications.waset.org/abstracts/search?q=shared%20residence" title=" shared residence"> shared residence</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20residence" title=" dual residence"> dual residence</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20best%20interests%20of%20the%20child" title=" the best interests of the child"> the best interests of the child</a> </p> <a href="https://publications.waset.org/abstracts/152760/joint-physical-custody-after-divorce-and-child-well-being" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152760.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1074</span> The Nonlinear Research on Rotational Stiffness of Cuplock Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liuyu%20Zhang">Liuyu Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Di%20Mo"> Di Mo</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiang%20Yan"> Qiang Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Liu"> Min Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the important equipment in the construction field, cuplock scaffold plays an important role in the construction process.

The issues addressed fit into the ongoing process of modernising family law regulations and their adaptation to changing social reality in Poland. The Polish legislator now faces a dilemma: whether to introduce into Polish law a developed substantive or procedural regulation of joint physical custody and then whether it should be considered a legal presumption. Joint physical custody after divorce or separation is theoretically possible in Poland. It can either follow from the court’s independent proposal based on the assessment of the circumstances or from the parenting plan submitted by parents wishing to jointly retain full parental authority. However, joint physical custody does not result directly from the Polish Family and Guardianship Code. Therefore, there is real legal uncertainty in this matter, which leads to different treatment of citizens by the public authorities and courts. Another problem is that joint physical custody is misunderstood by the Polish courts. The main thesis of the work is that joint physical custody does not only mean the system of symmetrical child care (50/50), and the possibility to award joint physical custody will require the courts to carefully weigh the pros and cons of such an arrangement in each individual case. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20physical%20custody" title="joint physical custody">joint physical custody</a>, <a href="https://publications.waset.org/abstracts/search?q=shared%20parenting" title=" shared parenting"> shared parenting</a>, <a href="https://publications.waset.org/abstracts/search?q=divorce" title=" divorce"> divorce</a>, <a href="https://publications.waset.org/abstracts/search?q=separation" title=" separation"> separation</a>, <a href="https://publications.waset.org/abstracts/search?q=parental%20authority" title=" parental authority"> parental authority</a> </p> <a href="https://publications.waset.org/abstracts/176316/the-problem-of-legal-regulation-of-joint-physical-custody-the-polish-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176316.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1072</span> The Effect of Tool Type on Surface Morphology of FSJ Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongfang%20Deng">Yongfang Deng</a>, <a href="https://publications.waset.org/abstracts/search?q=Dunwen%20Zuo"> Dunwen Zuo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An attempt is made here to join 2024 aluminum alloy plate by friction stir joining (FSJ) using different types of tools.

Study is carried out on the effect of pin, shoulder and eccentricity of the tool on the surface topography of the joint and the formation of the joint surface topography is analyzed. It is found that, eccentric squeezing action of the tool is the mainly motive power to form arc lines contour and flash structure. Little flash appears in the advancing side but with severe deformation, while the flash in the retreating side is heavy but with soft deformation. The pin of tool has a deep impact on the flash on the advancing side of the joints. Shoulder can widen the arc lines, refine arcs structure, reduce flash in the retreat side, but will increase the flash in the advancing side.

The paper is focused on the shear loading simulations. The aim of the work is to obtain a representative uniform distribution of shear loads along T-joint during the mechanical testing is. A new design of T-joint test procedure, numerical simulation and optimization of representative boundary conditions are presented. The different conditions and inaccuracies both in simulations and experiments are discussed. The influence of different parameters on stress and strain distributions is demonstrated on T-joint made of CFRP (carbon fiber reinforced plastic). A special test rig designed by VZLU (Aerospace Research and Test Establishment) for T-shear test procedure is presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=T-joint" title="T-joint">T-joint</a>, <a href="https://publications.waset.org/abstracts/search?q=shear" title=" shear"> shear</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20testing" title=" mechanical testing"> mechanical testing</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/17685/development-of-a-new-method-for-t-joint-specimens-testing-under-shear-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17685.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1070</span> Numerical Prediction of Bearing Strength on Composite Bolted Joint Using Three Dimensional Puck Failure Criteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Meon">M.

Since this approach involves with notching, a proper progressive damage model (PDM) need to be implemented and verified to capture existence of damages in the structure. A three dimensional (3D) failure criteria of Puck is established to predict the ultimate bearing failure of such joint. The failure criteria incorporated with degradation scheme are coded based on user subroutine executed in Abaqus. Single lap joint (SLJ) of composite bolted joint is used as target configuration.

The joint contact force is an important parameter during walking which increases the incidence of injury and degenerative joint disease. To our best knowledge, there are not enough evidences in literature on the muscular forces and joint contact forces in subjects with low back pain. Purpose: The main hypothesis associated with this research was that joint contact force of L4/L5 of non-specific chronic low back pain subjects was the same as that of normal. Therefore, the aim of this study was to determine the joint contact force difference between non-specific chronic low back pain and normal subjects. Method: This was an experimental-comparative study. 20 normal subjects and 20 non-specific chronic low back pain patients were recruited in this study. Qualysis motion analysis system and a Kistler force plate were used to collect the motions and the force applied on the leg, respectively. OpenSimm software used to determine joint contact force and muscle forces in this study. Some parameters such as force applied on the legs (pelvis), kinematic of hip and pelvic, peaks of muscles, force of trunk musculature and joint contact force of L5/S1 were used for further analysis. Differences between mean values of all data were measured using two-sample t-test among the subjects. Results: The force produced by Semitendinosus, Biceps Femoris, and Adductor muscles were significantly different between low back pain and normal subjects. Moreover, the mean value of breaking component of the force of the knee joint increased significantly in low back pain subjects, besides a significant decrease in mean value of the vertical component of joint reaction force compared to the normal ones. Conclusions: The forces produced by the trunk and pelvic muscles, and joint contact forces differ significantly between low back pain and normal subjects. It seems that those with non-specific chronic low back pain use trunk muscles more than normal subjects to stabilize the pelvic during walking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title="low back pain">low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20contact%20force" title=" joint contact force"> joint contact force</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic" title=" kinetic"> kinetic</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20force" title=" muscle force"> muscle force</a> </p> <a href="https://publications.waset.org/abstracts/88748/evaluation-of-joint-contact-forces-and-muscle-forces-in-the-subjects-with-non-specific-low-back-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88748.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1068</span> Effectiveness of Centromedullary Fixation by Metaizeau Technique in Challenging Pediatric Fractures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Arshad%20Ikram">Mohammad Arshad Ikram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We report three cases of challenging fractures in children treated by intramedullary fixation using the Metaizeau method and achieved anatomical reduction with excellent clinical results. Jean-Paul Metaizeau described the centromedullary fixation for the radial neck in 1980 using K-wires Radial neck fractures are uncommon in children. Treatment of severely displaced fractures is always challenging. Closed reduction techniques are more popular as compared to open reduction due to the low risk of complications. Metaizeau technique of closed reduction with centromedullary pinning is a commonly preferred method of treatment. We present two cases with a severely displaced radial neck fracture, treated by this method and achieved sound union; anatomical position of the radial head and full function were observed two months after surgery. Proximal humerus fractures are another uncommon injury in children accounting for less than 5% of all pediatric fractures. Most of these injuries occur through the growth plate because of its relative weakness. Salter-Harris type I is commonly seen in the younger age group, whereas type II & III occurs in older children and adolescents. In contrast to adults, traumatic glenohumeral dislocation is an infrequently observed condition among children. A combination of proximal humerus fracture and glenohumeral dislocation is extremely rare and occurs in less than 2% of the pediatric population. The management of this injury is always challenging. Treatment ranged from closed reduction with and without internal fixation and open reduction with internal fixation. The children who had closed reduction with centromedullary fixation by the Metaizeau method showed excellent results with the return of full movements at the shoulder in a short time without any complication. We present the case of a child with anterior dislocation of the shoulder associated with a complete displaced proximal humerus metaphyseal fracture. The fracture was managed by closed reduction and then fixation by two centromedullary K-wires using the Metaizeau method, achieving the anatomical reduction of the fracture and dislocation. This method of treatment enables us to achieve excellent radiological and clinical results in a short time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glenohumeral" title="glenohumeral">glenohumeral</a>, <a href="https://publications.waset.org/abstracts/search?q=Metaizeau%20method" title=" Metaizeau method"> Metaizeau method</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20fractures" title=" pediatric fractures"> pediatric fractures</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20neck" title=" radial neck"> radial neck</a> </p> <a href="https://publications.waset.org/abstracts/150084/effectiveness-of-centromedullary-fixation-by-metaizeau-technique-in-challenging-pediatric-fractures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150084.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1067</span> Analysis of Artificial Hip Joint Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Zameer">Syed Zameer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Haneef"> Mohamed Haneef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hip joint plays very important role in human beings as it takes up the whole body forces generated due to various activities. These loads are repetitive and fluctuating depending on the activities such as standing, sitting, jogging, stair casing, climbing, etc. which may lead to failure of Hip joint. Hip joint modification and replacement are common in old aged persons as well as younger persons. In this research study static and Fatigue analysis of Hip joint model was carried out using finite element software ANSYS. Stress distribution obtained from result of static analysis, material properties and S-N curve data of fabricated Ultra High molecular weight polyethylene / 50 wt% short E glass fibres + 40 wt% TiO2 Polymer matrix composites specimens were used to estimate fatigue life of Hip joint using stiffness Degradation model for polymer matrix composites. The stress distribution obtained from static analysis was found to be within the acceptable range.The factor of safety calculated from linear Palmgren linear damage rule is less than one, which indicates the component is safe under the design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hip%20joint" title="hip joint">hip joint</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20matrix%20composite" title=" polymer matrix composite"> polymer matrix composite</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20analysis" title=" static analysis"> static analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue%20analysis" title=" fatigue analysis"> fatigue analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20life%20approach" title=" stress life approach"> stress life approach</a> </p> <a href="https://publications.waset.org/abstracts/20794/analysis-of-artificial-hip-joint-using-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20794.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">356</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1066</span> Neural Networks for Distinguishing the Performance of Two Hip Joint Implants on the Basis of Hip Implant Side and Ground Reaction Force</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Parisi">L.

The condition of walking gait at normal velocity was used and carried out with each of the two hip joint implants assessed. Ground reaction forces’ kinetic temporal changes were considered in the first approach followed but discarded in the second one. Ground reaction force components were obtained from eighteen patients under such gait condition, half of which had a hip implant type I-II, whilst the other half had the hip implant, defined as type III by Orthoload®. After pre-processing raw gait kinetic data and selecting the time frames needed for the analysis, the ground reaction force components were used to train a MLP neural network, which learnt to distinguish the two hip joint implants in the abovementioned condition. Further to training, unknown hip implant side and ground reaction force components were presented to the neural networks, which assigned those features into the right class with a reasonably high accuracy for the hip implant type I-II and the type III. The results suggest that neural networks could be successfully applied in the performance assessment of hip joint implants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kinemic%20gait%20data" title="kinemic gait data">kinemic gait data</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20joint%20implant" title=" hip joint implant"> hip joint implant</a>, <a href="https://publications.waset.org/abstracts/search?q=hip%20arthroplasty" title=" hip arthroplasty"> hip arthroplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation%20engineering" title=" rehabilitation engineering"> rehabilitation engineering</a> </p> <a href="https://publications.waset.org/abstracts/14635/neural-networks-for-distinguishing-the-performance-of-two-hip-joint-implants-on-the-basis-of-hip-implant-side-and-ground-reaction-force" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14635.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1065</span> Measuring Audit Quality Using Text Analysis: An Empirical Study of Indian Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leesa%20Mohanty">Leesa Mohanty</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashok%20Banerjee"> Ashok Banerjee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Better audit quality signifies the financial statements of the auditee firm reflect true and fair view of their actual state of affairs, which reduces information asymmetry between management and shareholders, as a result, helps protect interests of shareholders. This study examines the impact of joint audit on audit quality. It is motivated by the ongoing debate where The Institute of Chartered Accountants of India (ICAI), the regulatory body governing auditors, has advocated the finance ministry and the Reserve Bank of India (RBI) for the mandatory use of joint audit in private banks to enhance the quality of audit. Earlier, the Government of India had rejected the plea by ICAI for mandatory joint audits in large companies stating it is not a viable option for promoting domestic firms. We introduce a new measure of audit quality. Drawing from the domain of text analytics, we use relevant phrases in audit reports to gauge audit quality and demonstrate that joint audit improves audit quality. We also, for robustness, use prevalent proxy for audit quality (Big N Auditor, ratio of audit fees to total fees) and find negative effect of joint audit on audit quality. We, therefore highlight that different proxy for audit quality show opposite effect of joint audit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=audit%20fees" title="audit fees">audit fees</a>, <a href="https://publications.waset.org/abstracts/search?q=audit%20quality" title=" audit quality"> audit quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Big%20N.%20Auditor" title=" Big N.

The organisms that cause prosthetic joint infections range from normal skin colonizers to highly virulent pathogens. The pathogens continue to evolve. While Staphylococcus aureus continues to be the leading organism, gram-negative bacilli account for approximately 7% of cases and that incidence is increasing. Methicillin-resistant S. aureus(MRSA) accounts for approximately 10% of all infections occurring in the community setting and 20% of those in the health care setting. The list of organisms causing PJI has expanded in recent years. It is important to have an understanding of which organisms may be causing a periprosthetic joint infection based on where the patient contracted it and their recent medical history. Also, recent technology has expanded rapidly and new methods to detect the pathogen and why we failed in detecting it. There are a number of explanations for the latter finding, perhaps the most important reason being the liberal use of antibiotics that interferes with the isolation of the infective organism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infection" title="infection">infection</a>, <a href="https://publications.waset.org/abstracts/search?q=periprosthetic" title=" periprosthetic"> periprosthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=hip" title=" hip"> hip</a>, <a href="https://publications.waset.org/abstracts/search?q=organism%20profile" title=" organism profile"> organism profile</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20infection" title=" joint infection"> joint infection</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20infection" title=" joint infection"> joint infection</a> </p> <a href="https://publications.waset.org/abstracts/159166/organism-profile-causing-prosthetic-joint-infection-continues-to-evolve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159166.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1063</span> A Numerical Study of Adherend Geometry on the Stress Distribution in Adhesively Lap Joint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Calik">Ahmet Calik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In present study, the effect of adherend geometry on the tensile strength of adhesively single lap aluminum structures joint, bonded was numerically studied using by three dimensional finite element model.

It was found that the precast joint of the proposed bridge showed the composite behavior efficiently before the failure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title="finite element analysis">finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=full-scale%20test" title=" full-scale test"> full-scale test</a>, <a href="https://publications.waset.org/abstracts/search?q=coping" title=" coping"> coping</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20performance" title=" joint performance"> joint performance</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20structure" title=" marine structure"> marine structure</a>, <a href="https://publications.waset.org/abstracts/search?q=precast" title=" precast "> precast </a> </p> <a href="https://publications.waset.org/abstracts/80628/composite-behavior-of-precast-concrete-coping-with-internal-connector-and-precast-girder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80628.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">205</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1060</span> Experimental Study on Connection Method of Precast Beam-Column Using CFRPS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harmonis%20Rante">Harmonis Rante</a>, <a href="https://publications.waset.org/abstracts/search?q=Rudy%20Djamaluddin"> Rudy Djamaluddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Herman%20Parung"> Herman Parung</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Sampebulu"> Victor Sampebulu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many research of FRP strengthening on beam-column joint have been done. They used FRP as a strengthening material but not as a connection method. This paper presents a result of experimental-study on connection method of precast beam-column using CFRP sheet to investigate the possibility of CFRP sheet to be a connecting material. Six specimens were prepared and tested to investigate the behavior of CFRP-s connection capacity. The performance of two-connection method is presented in this paper. Three specimens have been tested so far, they were specimen without belt, specimen using one belt and monolith specimen as a control specimen. Result indicated that FRP joint system without belt reached higher capacity than joint system using one belt, but both are lower than monolith joint. Capacity of joint system without belt is 90.6% and 62.5% for the joint system using one belt, respectively compared to the control specimen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=belt" title="belt">belt</a>, <a href="https://publications.waset.org/abstracts/search?q=CFRP-s" title=" CFRP-s"> CFRP-s</a>, <a href="https://publications.waset.org/abstracts/search?q=connection%20method" title=" connection method"> connection method</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthening" title=" strengthening"> strengthening</a> </p> <a href="https://publications.waset.org/abstracts/41015/experimental-study-on-connection-method-of-precast-beam-column-using-cfrps" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41015.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">251</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1059</span> Testing of the Decreasing Bond Strength of Polyvinyl Acetate Adhesive by Low Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Bo%C5%A1ka">Pavel Boška</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Bomba"> Jan Bomba</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%C3%A1%C5%A1%20Ber%C3%A1nek"> Tomáš Beránek</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji%C5%99%C3%AD%20Proch%C3%A1zka"> Jiří Procházka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When using wood products bonded by polyvinyl acetate, glues such as windows are the most limiting element of degradation of the glued joint due to weather changes. In addition to moisture and high temperatures, the joint may damage the low temperature below freezing point, where dimensional changes in the material and distortion of the adhesive film occur. During the experiments, the joints were exposed to several degrees of sub-zero temperatures from 0 °C to -40 °C and then to compare how the decreasing temperature affects the strength of the joint. The experiment was performed on wood beech samples (Fagus sylvatica), bonded with PVAc with D3 resistance and the shear strength of bond was measured. The glued and treated samples were tested on a laboratory testing machine, recording the strength of the joint. The statistical results have given us information that the strength of the joint gradually decreases with decreasing temperature, but a noticeable and statistically significant change is achieved only at very low temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesives" title="adhesives">adhesives</a>, <a
