Abrasive Flow Machining (AFM) is the method of finishing complex surfaces and internal channels with help extrusion pressure abrasive-laden viscoelastic polymer media. This paper based on developing a new AFM media using natural waste as base material. In article, viz. rice husk ash-based has been developed, subsequently, rheological analysis done, experimentation performed Anton-paar® rheomete...

This study aimed to construct three-dimensional (3D) anatomical models of the tongue domestic mammals veterinary interest. The tongues were obtained from didactic collection Laboratory Veterinary Macroscopic Anatomy in Surgery Department School Medicine and Animal Science, University Sao Paulo. Tongues a cow, dog, horse, pig selected for scanning creation 3D-printed models. printer used filamen...

By including acoustic-elastic interactions in a topology optimization based on the covariance matrix adaptation evolution strategy, we developed acoustic cloaks of optimal design that render an object unobservable through airborne and water-borne sounds. This strategy helps exploring topologies minimize scattering sounds around made from acrylonitrile butadiene styrene copolymers frequently use...

This paper presents experimental values for the coefficient of restitution (en) millimeter-sized ice particles colliding with massive walls at different temperatures. Three wall materials are tested: hardened glass, and Acrylonitrile butadiene styrene (ABS) polymer. The results show a high sensitivity to impact velocity Vi, where en decreases rapidly increasing Vi. also decrease in temperature ...

This research deals with the study of acrylonitrile-butadiene-styrene/polycarbonate (ABS/PC) totally derived from wastes electrical and electronic equipment (WEEE). The aim this is to investigate macroscopic use properties 100% recycled polymers compare them virgin materials. First, a preliminary work sorting characterization was necessary identify predominant polymer components in lots. Then, ...

The control of cell proliferation by gastrin has been investigated in a rat pancreatic tumour cell line, AR4-2J. Exogenous gastrin, 10-12 to 10-8 M, stimulated cell growth of thymidine-synchronised AR4-2J cells cultured over 48 h in serum-free medium. Cell lysates of AR4-2J cells contained an average of 4.5 and 3.5 pg gastrin per 106 cells, when grown in serum-supplemented or serum-free media, ...

We developed a new approach to produce individual immobilization devices for the head based on MRI data and 3D printing technologies. The purpose of this study was to determine positioning accuracy with healthy volunteers. 3D MRI data of the head were acquired for 8 volunteers. In-house developed software processed the image data to generate a surface mesh model of the immobilization mask. Afte...
