Nowadays, advanced turning processes are extensively being adopted to perform different types of operations such as straight turning, taper on Hastelloy, Nimonic, and Inconel, stainless steel, tool steel fabricate better quality cylindrical rotating parts miniature-bars, miniature-pins, miniature-electrodes, miniature-tools. This paper presents a review the previous research conducted miniature...

caspian miniature horse is a rare small horse in iran. in this horse, brachiocephalic trunk originates from the craniodorsal of the convex part of the aortic arch. it supplies the head, neck, forelimbs and cranial part of the thoracic cavity. in this reseach topographical location of brachiocephalic trunk arising from the aorta and its ramifications have been studied. five caspian miniature hor...

Today, disease interpretation of excised tissue is performed by analyzing biopsy specimens with a tabletop microscope [1]. While this method is effective, the process can be limited by sampling error, processing costs, and preparation time. In addition, the interpretive accuracy of the specimens can be affected by artefacts associated with tissue sectioning, paraffin embedding, and histochemica...

OBJECTIVE To quantify the temperature changes in the dental pulp associated with equine dental procedures using power grinding equipment. DESIGN A matrix experimental design with replication on the same sample was followed to allow the following independent variables to be assessed: horse age (young or old), tooth type (premolar or molar), powered grinding instrument (rotating disc or die gri...

A new approach to sample handling for powder X-ray diffraction analysis is presented that allows characterization of poorly prepared samples. The technique relies on vibrations generated in a sample holder to create movement of the powdered sample in the absence of macroscopic movement of the sample holder itself. The major benefits over conventional sample handling strategies are: 1) the abili...

A new laser-Doppler velocimeter (LDV) for high speed flow measurements (three-dimensional flows with speeds greater than 610 m/s) is being developed based in-part upon an existing low speed instrument capable of high resolution, near surface velocity vector measurements. The key technology for the instrument is a sub-miniature laser-Doppler velocimeter (SMLDV); a similar low-speed version of wh...

A campact Space-borne active Hydrogen Maser (SHM) frequency standard is being developed By the Observatory of Neuchhtel under the Swiss PRODEX program of ESA. The SHM instrument will be jl’own on the Radioastron (RA) mission in 2000 to be used as the reference clock for orbital Very Long Baseline Inte$erometry (VLBI) and for the red-ship experiment CRONOS. The SHM design is based on a miniature...

We present the design of an all-accelerometer inertial measurement unit (IMU). The IMU forms part of an intelligent hand-held microsurgical instrument that senses its own motion, distinguishes between hand tremor and intended motion, and compensates in real-time the erroneous motion. The new IMU design consists of three miniature dual-axis accelerometers, two of which are housed in a sensor sui...
