Austenitic stainless steels (ASSs) have an excellent corrosion resistance but relatively-low hardness and yield strength [1,2], leading to limited usage in applications that high values of hardness and wear resistance is necessary for material surface. Therefore, surface properties such as hardness must be improved using appropriate techniques. Mechanical surface treatments such as ultrasonic s...

Abstract. Future linear colliders of 1 TeV energy like TESLA at DESY require new techniques of precise alignment. The planned 33km long accelerator facility will be established in a subterraneous tunnel, which follows an equipotential expanse. The required accuracy for the vertical alignment of the accelerator components is 0.2mm per 600m. To fulfill this demand, a HLS with a free surface ("hal...

Cancer is one of the diseases which cause the highest death rate in XXI century. However, through years techniques and equipment used to fight with this disease improved there are still many opportunity to get better results. Nowadays, the attention is focused on precise cancerous cells place estimation. It is important for effective cancer treatment, but also it allows diminishing the unwanted...

The data provided herein include flow-mediated vasodilation responses, represented by changes in arterial diameter, and blood pressure in young adults after a single oral dose of edible emu oil or placebo (cross-over design). Ten healthy men and 10 healthy women participated. Increased blood flow in the antebrachial region was induced by inflating a pressure cuff and subsequently releasing the ...

In ultrasonic array imaging, 3D ultrasonic wavefields are normally recorded by an ultrasonic piezo array transducer. Its performance is limited by the configuration and size of the array transducer. In this paper, a method based on digital holographic interferometry is proposed to record the 3D ultrasonic wavefields instead of the array transducer, and the measurement system consisting of a pul...

A sensitive quantification of decabrominated diphenyl ether (deca-BDE) was achieved by optimizing the injection temperature, pressure and column system with gas chromatography mass spectrometry in selected ion monitoring mode. A simple one-step cleanup method with acid silica gel column chromatography showed the optimum efficiency and minimum matrix interference. Ultrasonic-assisted extraction ...

A new advanced system for Ultrasonic Peening (UP) of materials, details and welded elements was developed recently. The UP produces a number of beneficial effects in metals and alloys. Foremost among these is increasing the resistance of materials to surface-related failures, such as fatigue, fretting fatigue and stress corrosion cracking. The beneficial effect is achieved mainly by relieving o...

Ultrasonic motors have been expected as a leader of new actuators since 1980th when they were invented. Author has been conducted research on analysis of characteristics of ultrasonic motors, development of novel ultrasonic motors including multi-degree-of-freedom (DOF) ultrasonic motors, and application of ultrasonic motors for robotic field. In this paper, several results are described.

Non-contact ultrasonic, enables rapid testing of structures using ultrasonic tests that are not possible via conventional contact transducers. This paper reports on laser ultrasonic and air/gas coupled ultrasonic measurements that are performed remotely, do not require direct access to test area, do not need traditional ultrasonic coupling and do not have traditional C-scan fixture requirements...
