Comparison of Composites Properties Manufactured by Vacuum Process and Autoclave Process

Journal of Aeronautical Materials, 2017
Two kinds of prepregs ZT7G/LT-03A(unidirectional carbon fiber prepreg) and ZT7G3198P/LT-03A(plain carbon fabric prepreg) were used to manufacture three Bateches of composites by vacuum process and autoclave process respectively.

Composite ontology change operators and their customizable evolution strategies [PDF]

, 2012
Change operators are the building blocks of ontology evolution. Elementary, composite and complex change operators have been suggested. While lower-level change operators are useful in terms of finegranular representation of ontology changes ...

Unpaired composite fermion, topological exciton, and zero mode

, 2011
The paired state of composite fermions is expected to support two kinds of excitations: vortices and unpaired composite fermions. We construct an explicit microscopic description of the unpaired composite fermions, which we demonstrate to be accurate for

Behaviour and design of composite beams subjected to negative bending and compression [PDF]

, 2012
This paper investigates the behaviour of steel–concrete composite beams subjected to the combined effects of negative bending and axial compression. Six full-scale tests were conducted on composite beams subjected to negative moment while compression was

Composite GUTs: models and expectations at the LHC [PDF]

, 2011
We investigate grand unified theories (GUTs) in scenarios where electroweak (EW) symmetry breaking is triggered by a light composite Higgs, arising as a Nambu-Goldstone boson from a strongly interacting sector.

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

A novel post-weld treatment using nanostructured metallic multilayer for superior fatigue strength

Scientific Reports, 2023
Welded joints exhibit fatigue failure potential from weld geometry and characteristics of the heat affected zone. In order to counteract fatigue, structures and components require larger thicknesses resulting in heavier designs exhausting the finite ...
