Modular Planar Antenna at X-band for satellite communications [PDF]

, 2011
An antenna which has been conceived as a portable system for satellite communications based on the recommendations ITU-R S.580-6 [1] and ITU-R S.465-5 [2] for small antennas, i.e., with a diameter lower than 50 wavelengths, is introduced.

Arthroscopic Segmental Labral Reconstruction Using a Presutured Iliotibial Band Allograft Soaked in Bone Marrow Aspirate Concentrate

Arthroscopy Techniques, EarlyView.
Abstract Labral reconstruction is a surgical procedure in which a graft is used to replace irreparable acetabular labral tissue. Biologic augmentation with bone marrow aspirate concentrate harvested from the ipsilateral iliac crest is increasingly used to enhance graft incorporation and potentially improve functional outcomes, especially in patients ...

Medial Meniscus Allograft Transplant: Arthroscopic Soft Tissue Technique With Suture Tape Augmentation

Arthroscopy Techniques, EarlyView.
Abstract Meniscal allograft transplant (MAT) is gaining popularity for treating meniscus deficiency. Various MAT techniques are described. Bony techniques such as bone plugs and bone slot techniques are considerably more technically challenging but show better reduction of extrusion than all‐soft‐tissue technique.

Failure characteristics analysis of the inclined interlayer during water‐soluble cavity construction of underground salt caverns for large‐scale energy storage

Deep Underground Science and Engineering, EarlyView.
In the process of water‐soluble cavern construction of salt cavern energy storage, since the interlayer does not dissolve in water easily, sudden collapse will cause engineering accidents such as bending and damage of the inner tube of the cavern.
