The cutter spacing relate to the rock breaking efficiency of TBM. double disc cutters rolling marble model is established by using ABAQUS based on principle specific energy calculation. effect amount analyzed, and in different calculated. simulation results show that geological conditions marble, when penetration 6mm, 78mm smallest. broken experiment was carried out comprehensive test bench. wi...

A 28-year-old veteran presented to the Wilford Hall dermatology clinic in San Antonio, Texas, with a six-month history of a rash that his primary care physician diagnosed as molluscum contagiosum. The rash consisted of clusters of 3 to 6mm yellowish papules with erythematous borders that concentrated on the extensor surfaces of his extremities, lower back, and buttocks. A biopsy determined that...

This paper presents a new architecture style for the design of a parallel floating point multiplier. The proposed architecture is a synergy of trees and arrays. Architectural models were designed to implement the 53-bit mantissa path of the IEEE standard 754 for floating point multiplication, and tested for functionality in Verilog. The design, which was done in dual-rail domino, was simulated ...

Abstract The AUTODYN-2D simulation software was used to study the jet formation of single-cone and biconical shaped charge liner damage influence on RHA target. numerical results show that compared with typical structure, head formed by is faster has better penetration performance On this basis, standoff, cone angle line thickness characteristics target under studied. when standoff increases fr...

INTRODUCTION: Many acromioclavicular joint injuries involve damage to the coracoclavicular (CC) ligaments. Some current techniques for CC ligament reconstruction utilize a hole drilled in the coracoid process for placement of a fixation device. Such a hole may increase the probability of coracoid fracture; however, there are no studies in literature that have attempted to evaluate the effects o...

A new procedure to determine copper has been proposed using an irreversible and disposable multilayer optical test strip. Two layers form the sensing zone: a copper sensitive and a dialysis layer. The test strip is characterised to be a disposable polyester sheet contained in a circular film 6mm in diameter and 25 mm in thickness, with all reagents necessary to produce a selective response. The...

This paper presents the first successful demonstration of all-optical MEMS (microelectromechanical system) fiber endoscope for OCT (optical coherence tomography) measurement. A MEMS optical scanner for spatial light modulation has been assembled in the endoscope probe head (φ 6mm) with optical components and a photovoltaic cell. Actuation energy for the MEMS scanner is optically supplied by usi...

proposed for use as skeletal anchorage in orthodontic treatment.1-5 In 1992, Wehrbein and colleagues, in collaboration with the Straumann Institute, introduced the Orthosystem*—a sandblasted, chemically treated mini-implant that is narrower (3.3mm), but longer (4mm or 6mm), than previous types.6-9 More recently, Giancotti and colleagues showed a step-by-step procedure for insertion of the Strau...

On palpation, sub-mental bony spur was felt. The defect was associated with limitation of neck extension. Surgery was offered. At operation the extent of the sinus was about 4-6mm. The skin defect along with its cranial and caudal lesions was excised. The surgical wound was closed with multiple z-plasties (Fig. 2). The postoperative recovery was uneventful. Histopathology of the specimen showed...

Axisymmetric vibration of an infinite piezolaminated multilayer hollow cylinder made of piezoelectric layers of 6mm class and an isotropic LEMV Linear Elastic Materials with Voids layers is studied. The frequency equations are obtained for the traction free outer surface with continuity conditions at the interfaces. Numerical results are carried out for the inner, middle, and outer hollow piezo...
