Planning and design procedure of an open pit mining project just can be started after ultimate pit determination. In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price. Metal price fluctuations in recent years were exaggerated and impose...
We study a low-energy effective field theory (EFT) describing the NN system in which all exchanged particles are integrated out. We show that fitting the residue of the S1 amplitude at the deuteron pole, rather than the S1 effective range, dramatically improves the convergence of deuteron observables in this theory. Reproducing the residue ensures that the tail of the deuteron wave function, wh...
Material characterisation is often performed by uniaxial loaded cylindrical specimens. When the material in question is anisotropic in nature, the transverse behaviour of these specimens is recorded and analysed with respect to the material orientation to determine the relevant material properties for development of constitutive models. During low strain rate testing, measurements of the transv...
In our ongoing studies of both extinct and extant hermit crabs (Paguroidea Latreille, 1802), we have observed recorded a number morphological changes that taken place between Early Jurassic times (c. 185 million years ago) the present day. Species compositions paguroid assemblages from marine Upper Lower Cretaceous rocks in Europe are here compared with those modern settings. Basal paguroids cy...
INTRODUCTION Bone mineral density (BMD) is an important factor in the examination of the performance of bone instrumentation both in and ex vivo, and until now, there has not existed a reliable technique for determining BMD at the precise location of such hardware. This paper describes such a technique, using cadaveric human sacra as a model. METHODS Nine fresh-frozen sacra had solid and holl...
Specimen transfer under controlled environment conditions, such as temperature, pressure, and gas composition, is necessary to conduct successive complementary in situ characterization of materials sensitive to ambient conditions. The in situ transfer concept is introduced by linking an environmental transmission electron microscope to an in situ X-ray diffractometer through a dedicated transmi...
Generally, thin cylindrical shells are susceptible for geometrical imperfections like non-circularity, non-cylindricity, dents, swellings etc. All these geometrical imperfections decrease the static buckling strength of thin cylindrical shells. In this work, neighbourhood effect of two circumferential short dents on the buckling behaviour of thin short stainless steel cylindrical shell is studi...
