Evaluating the effectiveness of Baker's procedure in restoring functionality in neglected Achilles tendon injuries

Background: Neglected Achilles tendon injuries present a significant challenge in orthopedic practice, often requiring complex surgical interventions for effective treatment. This study aims to evaluate the functional outcomes of patients with neglected Achilles tendon injuries treated using Baker's procedure, a surgical technique designed for complex cases. Methods: This prospective interventional study was conducted at multiple medical centers in Dhaka, Bangladesh, from January 1, 2012, to May 31, 2013. It included 42 patients aged 18 to 60 years with signs of old Tendo-Achilles rupture. Participants were selected based on specific inclusion and exclusion criteria and underwent Baker's Procedure. Postoperative assessments included pain levels, ankle stiffness, calf-muscle weakness, footwear restrictions, range of motion, and patient satisfaction, evaluated using the Juhana Leppilahti modified score. Result: The majority of patients (85.71%) reported no pain post-treatment, while 14.29% experienced mild pain. Ankle stiffness was absent in 71.43% of the patients and mild in 28.57%. Calf-muscle weakness varied, with 64.29% showing no weakness, 28.57% mild weakness, and 7.14% moderate weakness. Footwear restrictions were minimal, with 92.86% reporting no restrictions. Active range of motion was normal (≤5°) in 64.29% of patients and mildly limited (6-10°) in 35.71%. Patient satisfaction was high, with 71.43% being 'Very satisfied' with their treatment outcomes. Conclusions: The study demonstrates that Baker's Procedure is an effective surgical intervention for neglected Achilles tendon injuries, leading to significant pain relief, restored functional mobility, and high patient satisfaction. These findings suggest that with appropriate surgical and rehabilitative care, patients with complex Achilles tendon injuries can achieve favorable outcomes, emphasizing the importance of tailored surgical approaches in orthopedic practice

Proposal of Reasonable Fill Construction Management Index in Fill Loading with Vacuum Consolidation Method Based on FEM Analyses

Vacuum consolidation method (VCM) is one of the recent methods for the improvement of soft ground. This method can forcibly drain pore water, and increase ground strength by loading of the vacuum pressure. A fill loading with vacuum consolidation method (FLVCM) is considered to be able to control lateral flow and upheaval of surrounding area during the rapid fill construction. However, the behavior of this combination on the ground deformation is not fully clarified on FLVCM, fill design and site management is depending on the experienced technique. In this study, numerical simulation has been carried out by finite element method (FEM) for the quantitative evaluation of the deformation suppression effect of FLVCM on the soft grounds of ariake clay, Japan. The utility of FLVCM was confirmed from comparison with the observed and the analytical ground deformation. In addition, the numerical simulation have been carried out under the various conditions of vacuum preand post-loading pressures and fill speeds, and it is suggested that the reasonable construction management index can be easily obtained by the site measurement of deformation

On the Potential of Optical Nanoantennas for Visibly Transparent Solar Cells

This study aims to determine the maximum possible energy conversion efficiency of visibly transparent solar cells using the detailed balance limit (also known as the Shockley–Queisser limit) and compare it to the efficiency of traditional single-junction solar cells. To achieve this, a new optical nanoantenna has been designed to absorb incoming light selectively, enhancing the average visible transmission while maintaining high absorption in the infrared and UV regions. The color appearance of the antennas has also been evaluated through colorimetrical characterization. Our findings indicate that it is possible to achieve high average visible transparency and energy conversion efficiency of over 80 and 18%, respectively, by carefully selecting semiconductor materials. Such solar cells are versatile enough to be integrated seamlessly into smart windows, agrivoltaic concepts in open and protected cultivation, mobile devices, and appliances without compromising their appearance or functionality. The dimensions and optics of the proposed antennas and visibly transparent solar cells have been thoroughly discussed

SUGGESTION OF RATIONAL MANAGEMENT FOR THE FILL CONSTRUCTION WITH VACUUM CONSOLIDATION

Because of the limited land area and dense population, it is inevitable to construct structures on the soft ground, therefore a variety of counter･measures for soft ground have been devised and performed around the country. Vacuum consolidation method is an advanced one among these methods, which have been devised up to now. However, there are no perfect theories and mature experience about this kind of consolidation method yet. The field investigation therefore was carried out, aiming at the prediction of influence range and corresponded measures. Meanwhile the laboratory simulating model test was carried out to clarify the behavior and promoting effect of vacuum consolidation method. Result comparison between them will reveal some guidelines for ground measurement

The effect on punching shear failure in centrally loaded ground-supported concrete slabs for different aspects like slab thickness, size and the position of reinforcement bar, and the strength of concrete using a validated FE model

The effect of slab thickness, presence of reinforcement and concrete strength on punching shear capacity of the ground-supported concrete slabs (GSCS) is an important issue in Industrial Ground-supported slab construction. In this study, a three-dimensional nonlinear finite element (FE) model for GSCS was validated with three experimental results from literature and used to assess those effects. A Concrete damaged plasticity model in ABAQUS2020 software with a suitable simulation technique and the theory-based material property was adopted. The results of FE models and predictions of the Technical Report34 (TR34) of the Concrete Society were compared with the experimental results. The average FE predicted/Experimental punching shear capacity ratio was 0.93 with a 0.06 standard deviation and the average TR34 predicted/Experimental punching shear capacity ratio was 1.01 with 0.06 standard deviation. However, the average TR34 predicted/FE predicted punching shear capacity ratio was 1.08 with a 0.13 standard deviation. TR34 prediction was little bit liberal. The results of 72 FE models were compared with the TR34 prediction. The average TR34 predicted/FE predicted punching shear capacity ratio is 1.17 with a 0.21 standard deviation. TR34 prediction was liberal compared to FE prediction. The study showed that the effects of an increase of Slab thickness, Concrete strength, and reinforcement were positive in both FE and TR34 predictions, whereas TR34 predictions were conservative up to a certain slab thickness around 115–130mm for concrete grade 20–40 MPa. As concrete strength and thickness increase, TR34 predictions become more liberal. The bottom layer reinforcement provides greater strength, however, TR34 was unable to predict that
