This workbook is a result of several years experience in applying geographic information systems (GIS) technology to typical forestry, natural resource management, and environmental problems. Many of the terms and concepts introduced in this book have been compiled from a variety of different sources. These include some of the prevalent text books in the field, but most have been firmly implant...

statement of problem: thermal injury during dental implant placement and restoration is a clinical concern as it may cause bone damage and compromise osseointegration. the threshold level for heat-induced cortical bone necrosis is 47°c for 60 seconds. objectives: to measure the amount of heat transferred to the implant-bone interface when a two-piece or one-piece abutment was prepared in vertic...

My time as interim editor is over. I hand over the reins to Dr George Larcos. As of this issue, the ASUM Ultrasound Bulletin will be no longer. It will be replaced with Australasian Journal of Ultrasound in Medicine. In keeping with an increase in the number of quality peer reviewed articles, this is a positive step. WFUMB 2009 has about 700 online submitted abstracts. This huge number of abstr...

Presents article is deal with optimization of the fixture for end milling process, the most important objective being the minimization of work piece deformation by changing the layout of fixture elements and the clamping forces. The main objective of this work has been the optimization of the fixtures Work piece deformation subjected to clamping forces for End milling operation. The present ana...

introduction: some clinicians use a handheld screw driver instead of a torque wrench to definitively tighten abutment screws. the aim of this study was to compare the removal torque of one-piece and two-piece abutments tightened with a handheld driver and a torque control ratchet. methods: 40 iti implants were placed in acrylic blocks and divided into 4 groups. in groups one and two, 10 iti one...
