We investigated the antitumor effects and tissue distribution of adriamycin (ADR) incorporated into a hydroxyapatite (HAP) bead in a cancer rat model bearing Swarm rat chondrosarcoma. The Porous HAP bead (8.48 mm in diameter, 531 +/- 0.7 mg in weight) was used as a model bone graft. One ADR-HAP bead (ADR 0.4 mg-6.0 mg/bead) was implanted s.c. into a Sprague-Dawley rat at 6 days postinoculation ...

This paper considers a 3-D thermos-mechanical analysis to investigate the effect of welding direction, tack weld, root gap and process on deformation in hub flange pipe joint. Multi-pass for single ‘V’ butt-weld joint geometry is simulated weld path used with realistic bead. 3 different direction (2-path, 4-path diagonally, from bottom) are analyzed how presence or absence affects was analyzed....

[1] A technique for visualizing particle transport in the interior of a porous medium is presented. The technique, which includes the construction of a translucent medium and the use of laser-induced fluorescence for particle tracking, was used to examine the behavior of a dilute suspension of negatively charged, micron-sized particles in the interior of uniform glass bead packs during one-dime...

We used a 10-μm-diameter fluorescent bead as a test object for 3D microscopy, and independently determined its structure by examining 1-μm-thick physical sections of the bead. Images of the full bead on different 3D microscopes revealed a number of aberrations and distortions. Images also showed evidence for absorption and/or scattering on all confocal and wide-field microscopes tested, but not...

Vertical oscillation arc welding for narrow gap gas metal (NG-GMAW) has a relatively simple structure, and it is widely used in all-position pipeline field welding. However, some shortcomings, such as incomplete fusion defects on the sidewall interlayer. Aiming at resolving these mathematical model proposed to obtain appropriate parameters different positions. In this model, response surface me...

Wire + arc additive manufacturing is an welding process that uses non-consumable tungsten electrodes to produce the weld. The material used in this study a titanium, carbon, zirconium, and molybdenum alloy physically chemically stable has good performance for use as high-temperature heating element. In study, experiments are designed based on central composite design, single-layer wire performe...

A Cerebellar Model Articulation Controller(CMAC-) based modelling method and closed-loop control system were developed to estimate and control the weld fusion for measuring the topside and backside bead widths of the weld pool in High Power Direct Diode Laser (HPDDL) welding. Because of the difficulty in using backside sensor, a topside weld pool geometry is measured using a topside vision sens...
