Recent advances in technology on two fronts, 1) the fabrication of large-diameter pistons and cylinders with good geometry, and 2) the ability to measure the dimensions of these components with high accuracy, have allowed dead-weight testers at the National Institute of Standards and Technology (NIST) to generate pressures that approach total relative uncertainties previously obtained only by m...

This paper presents the procedures used for determining and defining the tonnage and grade of the coalfields of Kangal basin from the developed GIS-aided block model. In this work, firstly, all the lithological logs of drill holes and chemical analysis data of core in the basin were analyzed with the help of geostatistics, and then the digital raster maps of each one of the attributes such as t...

We studied nine patients who had had a transtrochanteric anterior rotational osteotomy, as developed by Sugioka, for osteonecrosis of the femoral head. At a mean of 2.5 years after the initial operation we carried out a histological study of the previously necrotic femoral head which had not shown collapse of the new primary weight-bearing site. In seven joints, there was proliferation of fibro...

The southeastern United States has a promising source for renewable energy in the form of woody biomass. To meet the energy needs, energy plantations will likely be utilized. These plantations will contain a high density of small-stem pine trees. Since the stems are relatively small when compared with traditional product removal, the harvesting costs will increase. The purpose of this research ...

The Mineral Potential Project currently being undertaken in British Columbia requires estimation d unknown mineral resources. The method of resource assessment known as the BC Mineral Resource Assessment Process [19931. is described by Kilby (1995, this volume) and in Grunsky et al. (1.994). The method is based on the three-part ssessment methodology developed by the United States Geologica...

In the whole process of cement production, electricity consumption a raw material mill accounts for about 24% total. Based on statistics system 1005 production lines in China between 2014 and 2019, it is found that average preparation all clinker 2019 was 25.2 kWh/t. The different-tonnage varies with time. comparison high-tonnage ones, low-tonnage has wider distribution. dropped from 30.88 kWh/...
