1. Comparison of two endoscopic spine surgical techniques
SUMMARY OBJECTIVE: The objective of this study is to compare the clinical outcome among patients who are surgically treated for lumbar disc herniation by transforaminal and interlaminar endoscopy techniques. METHODS: For the treatment of lumbar disc herniation, 31 patients were assigned to undergo the interlaminar technique and 24 patients the transforamin

2. Manejo da administração intratecal de nusinersena em adolescentes e adultos com atrofia muscular espinhal 5q e cirurgia prévia de coluna
RESUMO Introdução: A atrofia muscular espinal (AME) é uma desordem neurodegenerativa dos motoneurônios inferiores frequentemente associada à ocorrência de deformidade da coluna vertebral. Nusinersena é um oligonucleotídeo antisense que aumenta os níveis da proteína SMN, sendo administrado através de injeções lombares intratecais frequentes. Ass

3. Effect of Suture on Mechanical Properties of Stitched Thermal Protection Sandwich
This paper investigates the tensile properties and bending performances of stitched thermal protection structure in engineering, and the effect of stitching density on mechanical properties, via a model of ceramic-aerogel stitched sandwich. With the help of ANSYS, titanium alloy bottom plate was added to the bottom surface of the thermal protection structure

4. Evaluation of the stiffening mechanism based on micro-sized particle inclusions in laminated composites
Rigid particles have been incorporated into laminated composites, especially to enhance their bending performance attributed to the stiffening of the matrix phase (i) and the increased interlaminar shear resistance (ii). In order to better evaluate the improvement mechanism provided by the particulate inclusions, this work investigates the incorporation of m

5. Influencia del calcio en la retención de humedad por arcilla
ABSTRACT Bentonite as a raw material is an economical alternative to produce desiccants. The literature indicates that it is a good water adsorbent in relation to the desiccants commonly used in industry (silica gel, molecular sieve). In this sense, it is a valid alternative and an economic option since the clay is a natural compound, which makes it environm

6. Finite Element Simulation of Interlaminar and Intralaminar Damage in Laminated Composite Plates Subjected to Impact
Abstract Here In this study, the composite laminates subjected to transverse impact with consideration interlaminar and intralaminar damage based on Cohesive Zone Model (CZM) and Progressive Damage Model (PDM) are investigated by numerical analysis using ABAQUS commercial finite element code. The delamination in stacking ply with the same fiber orientation

7. An Evaluation of the Dielectric Barrier Discharge Treatment on the Mechanical, Structural and Morphological Properties of Carbon Fibers
ABSTRACT: Carbon fibers (CFs) have been widely applied in the manufacture of polymeric composites. The mechanical properties of these composites depend on the adhesion in the matrix/CF interface. Since the CFs have poor adhesion properties, a surface treatment of the CFs becomes necessary. The plasma process used in this work was the dielectric barrier disch

8. Mode I Interlaminar Fracture Toughness Analysis of Co-Bonded and Secondary Bonded Carbon Fiber Reinforced Composites Joints
Aiming to reduce aircraft weight, aeronautic industry seeks alternative materials and processes used to join its different structural parts. An option to traditional methods are high performance adhesive joints, which reduce weight, number of parts and component final cost, also resulting in higher strength structures. Although, the lack of experimental data

9. On the Free Vibration Analysis of Laminated Composite and Sandwich Plates: A Layerwise Finite Element Formulation
Abstract In this paper, a new higher-order layerwise finite element model, developed earlier by the present authors for the static analysis of laminated composite and sandwich plates, is extended to study the free vibration behavior of multilayer sandwich plates. In the present layerwise model, a first-order displacement field is assumed for the face sheets,

10. Mechanical Characterization of Basalt and Glass Fiber Epoxy Composite Tube
The application of basalt fibers are possible in many areas thanks to its multiple and good properties. It exhibits excellent resistance to alkalis, similar to glass fiber, at a much lower cost than carbon and aramid fibers. In the present paper, a comparative study on mechanical properties of basalt and E-glass fiber composites was performed. Results of app

12. On the Decreasing Flexural Modulus of Glass/Vinylester Composite Beams Up to Failure State
Abstract The comparison of the failure state for composite laminates under bending and tensile loads is a well-known issue which has been intensively discussed in the literature. The scope of the current work is to investigate the appropriate method of the flexural modulus of the composite laminates by the aid of experimental and numerical approach. The prim
