Ball burnishing is a technological finishing process based on plastic deformation of the objective surface by means of a hard ball gliding over it. Along with its easiness of application, possible on the same machine where machining was performed [1], burnishing is a comprehensive process able to achieve surface roughness improvements, and compressive residual stresses up to deep layers of the ...

Ultrasound-assisted extraction (UAE) was evaluated as a simpler and more effective alternative to conventional extraction methods for the isolation of curcuminoids from turmeric plant rhizomes. The turmeric samples were extracted under indirect sonication in an ultrasonic bath, and compared with the conventional methods. It was found that the yield of ultrasound-assisted extraction was approxim...

Euphorbia tirucalli (E. tirucalli) is now widely distributed around the world and is well known as a source of traditional medicine in many countries. This study aimed to utilise response surface methodology (RSM) to optimise ultrasonic-assisted extraction (UAE) conditions for total phenolic compounds (TPC) and antioxidant capacity from E. tirucalli leaf. The results showed that ultrasonic temp...

Induction heating treatment (IHT) has recently been used to improve the bioactivity and biocompatibility of titanium its alloys, greatly related formation nanoscale oxide coating. In this work, effect ultrasonic on IHT oxidation behavior pure investigated. Ultrasonic-assisted was carried out for 13, 20 25 s. Submicro-/nano-scale morphological coatings with rutile anatase TiO2 were prepared surf...

Ultrasonic-assisted grinding (UAG) is widely used in the manufacture of hard and brittle materials. However, process removal mechanism was never elucidated its potential yet to be fully exploited. In this paper, material analyzed by ultrasonic-assisted scratching. Three distinct surfaces (S1, S2, S3) were selected on basis braided laminated structure fiber bundles. The scratching experiment car...

We propose an ultrasound (US)-based technique for imaging vibrations in the blood vessel walls and surrounding tissue caused by eddies produced during flow through narrowed or punctured arteries. Our approach is to utilize the clutter signal, normally suppressed in conventional color flow imaging, to detect and characterize local tissue vibrations. We demonstrate the feasibility of visualizing ...

There is a huge demand in the production of microstructures by a non-traditional method which is known as Micro-EDM. Micro-EDM process is based on the thermoelectric energy between the workpiece and an electrode. Micro-EDM is a newly developed method to produce micro-parts which in the range of 50 μm -100 μm. Micro-EDM is an efficient machining process for the fabrication of a micro-metal hole ...

This study investigates the dry and near-dry electrical discharge machining (EDM) milling to achieve a high material removal rate (MRR) and fine surface finish for roughing and finishing operations, respectively. Dry EDM uses gas and near-dry EDM applies a liquid-gas mixture as the dielectric medium. Experimental studies leading to the selection of oxygen gas and copper electrode for high MRR d...

Electronic document management (EDM) relates to several modern information technologies. Little research on methods for practical development of EDM exists. Such method, based on the genre theory of organizational communication, was adopted by a team of EDM consultants who used and engineered it further along with their customer cases for developing EDM systems. These experiences were gathered ...
