The non-homogeneous and anisotropic nature of composites poses challenges during machining, requiring the use specialized cutting tools. GFRP materials were selected for their excellent elasticity, corrosion resistance, high strength, making them ideal applications in aerospace automotive industries. In this work, surface quality UD-GFRP composite bars CNC machining diverse conditions (dry, wet...

The present work deals with the transferability of Friction Riveting joining technology from laboratory equipment to adapted in-house, low-cost machinery. A G13 drilling machine was modified for requirements selected technique, and joints were performed using polyethermide plates AA2024 aluminum alloy rivets 6 mm diameter. This diameter not previously reported Riveting. produced mechanically te...

Root–soil mechanical interactions are of vital importance in soil reinforcement by plant roots. However, it is unclear how the angles roots affect root–soil interactions. To better understand effect this factor on interactions, pullout tests were conducted alfalfa (Medicago sativa L.) with five root diameter groups (0.10–0.30 mm, 0.31–0.50 0.51–0.70 0.71–0.90 mm and 0.91–1.10 mm) four embedding...

Degeneration and tearing of the long head of the biceps brachii tendon (LHBT) are common intra-articular findings, and surgical intervention including tenodesis or tenotomy is beneficial. A new arthroscopic shoulder technique may be performed through an anterior portal while one is viewing from a posterior portal: (1) Visualize the intra-articular biceps tendon. (2) Identify the segment of the ...

BACKGROUND The newest generation of meniscus repair devices is designed to combine the benefits of the all-inside technique with the biomechanical properties of sutures. HYPOTHESIS New flexible all-inside suture anchors have better fixation strength than rigid anchors, but there is no difference when compared to conventional horizontal and vertical mattress sutures. STUDY DESIGN Controlled ...

BACKGROUND In arthroscopic surgery, the suture anchor technique has become popular for rotator cuff repair. Preoperative evaluation of the bone microstructure is of utmost importance because, especially in elderly patients, osteoporotic changes may cause anchor pullout, which results in failure of rotator cuff repair. Many groups have reported humeral microstructural analysis; however, most stu...

PURPOSE The purpose of this investigation was to conduct an evidence-based systematic review (EBSR) of peer-reviewed articles from the last 30 years about the effect of different service delivery models on speech-language intervention outcomes for elementary school-age students. METHOD A computer search of electronic databases was conducted to identify studies that addressed any of 16 researc...

Bone drilling is one of the most common operations used to repair fractured parts of bones. During a bone drilling process, microcracks are generated on the inner surface of the drilled holes that can detrimentally affect osteosynthesis and healing. This study focuses on the investigation of microcracks and pullout strength of cortical-bone screws in drilled holes. It compares conventional surg...

Various fixation techniques have been described for ruptured distal biceps tendons. The authors hypothesized that no significant differences would be found between the mean failure strength, maximum strength, and stiffness of the interference screw and hybrid technique. Fourteen fresh-frozen human cadaveric elbows were prepared. Specimens were randomized to either interference screw or hybrid c...
