The goal of this research is to carry out a 3-dimensional finite detail approach evaluation composite plate cracked under thermal loading. results the mechanical properties composite, orientation angle fibers, geometric form plate, loading and crack length had been studied show their influence on variation integral J. It concluded that J increases with increase size, temperature reduce in fiber...

BACKGROUND AND OBJECTIVES To produce controlled, spatially confined thermal effects in dermis. STUDY DESIGNS/MATERIALS AND METHODS A 1 W, 1,500 nm fiber-coupled diode laser was focused with a high numerical aperture (NA) objective to achieve a tight optical focus within the upper dermis of skin held in contact with a glass window. The delivery optics was moved using a computer-controlled tran...

Ceramic thermal barrier coatings are commonly used in gas turbine hot components (e.g., combustor liners/buckets and guide vane platforms). In components that are only partially coated or have cooling-air outlets, coating-end stress singularities may lead to the spallation of the coating. Depending on the geometry of the transition from coated to uncoated material, the severity of the stress si...

Laser-induced damage on fused silica optics remains a major issue that limits the promotion of energy output of large laser systems. Subsurface impurity defects inevitably introduced in the practical polishing process incur strong thermal absorption for incident lasers, seriously lowering the laser-induced damage threshold (LIDT). Here, we simulate the temperature and thermal stress distributio...

Near-infrared photoimmunotherapy (NIR-PIT) is a newly-established cancer treatment which employs the combination of an antibody-photoabsorber conjugate (APC) and NIR light. When NIR light is absorbed by APC-bound tissues, a certain amount of heat is generated locally. For the most part this results in a subclinical rise in skin temperature, however, excessive light exposure may cause non-specif...

Thermal neutrons/DNA replication/DNA repair The degree of inhibition of DNA replication and the level of DNA repair synthesis induced by thermal neutron irradiation was determined in human lymphoblastoid cell lines. Dose response experiments revealed that, when compared with equivalent doses of 60Co-ƒÁ-irradia tion, thermal neutrons gave rise to similar levels of inhibition of DNA replication b...

Background: The use of lasers has become increasingly common in the field of medicine and dentistry, and there is a growing need for a deeper understanding of the procedure and its effects on tissue. The aim of this study was to compare the erbium-doped yttrium aluminium garnet (Er:YAG) laser and conventional drilling techniques, by observing the effects on trabecular bone microarchitecture and...
