A simple bone cyst in the upper end of the humerus presents a common surgical problem. lt is usually diagnosed in childhood or adolescence because of a pathological fracture. Rarely the cyst heals after fracture; usually it persists and needs surgical treatment if the risk of recurrent fractures is to be avoided. Curettage of the cyst and packing of the cavity with bone chips is the usual treat...

Useful in a variety of oral surgery procedures, piezosurgery has therapeutic features that include a micrometric cut (precise and secure action to limit tissue damage, especially to osteocytes), a selective cut (affecting mineralized tissues, but not surrounding soft tissues), and a clear surgical site (the result of the cavitation effect created by an irrigation/cooling solution and oscillatin...

In order to realize a wide area of a soft sensor skin covering the entire body of robots, several ideas of wireless tactile elements have been presented[1][2]. But those papers described only the sensing chip designs, and no methods of their equipment on a real robot had been shown. In this paper we propose a 1-D film coil array to power wireless tactile sensor chips and obtain sensing signals ...

Early implant placement is one treatment option for implant therapy following a single-tooth extraction in the anterior maxilla. In this article some key factors are presented to analyze and follow in an effort to obtain a predictable and acceptable esthetic result. The creation of predictable peri-implant esthetics requires proper preservation of the osseous and soft tissues around the failing...

SIMMONS, DAVID J., AND GEORGE NICHOLS, JR. Diurnal periodicity in the metabolic activity of bone tissue. Am. J. Physiol. LO(Q): 411-418. 1966. -Studies of the metabolism of bone cells in the metaphyses of the rat femur (distal) and tibia (proximal) have established that collagen synthesis and new bone formation is diurnally regulated. Significantly greater amounts of glycine-Q-Cl4 were initiall...

The reverse engineering process for VLSI chips is a complex operation that can cost from $10,000 for the simplest chips to hundreds of thousands of dollars for complex chips. In this study, we present an overview of the process of reverse engineering VLSI chips. The study outlines the steps involved in the process of reverse engineering chips as well as the different techniques used to extract ...

An otherwise healthy girl, ten years old, first complained of pain and swelling in the right scapula in June 1953. There was no interference with function of her shoulder or arm. Radiographs gave evidence of an expanding cystic tumour in the body of the scapula. All other investigations showed no abnormality. The lesion was explored. The cyst was opened, curetted and filled with bone chips. It ...
