Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
If rock can be thought of as the foundation upon which all life on Earth stands, minerals are the foundation upon which rocks are built. Essentially, minerals are the most simple chemical compounds that make up rocks. This book is designed to take the reader on a tour of the various mineral groups, the unique characteristics that set one mineral apart from another, the features different groups of minerals share, and the roles minerals play in the rocks themselves.
Data on the geomagnetic field in the Balkan region and state borders were regarded as confidential information for a long time. Unfortunately this meant that geomagnetic field information was confidential information. The Republic of Macedonia was in a complicated situation because geomagnetic investigations were carried out by experts from Belgrade, Serbia and Montenegro. When Macedonia became an independent country, a team of experts from the Faculty of Mining and Geology, Department for Geology and Geophysics in Stip and Faculty of Natural Sciences and Mathematics, Institute of Physics in Skopje, started activities to establish a Geomagnetic Observatory in Macedonia. In the last four years, with the help of Dr. Jean Rasson from Institut Royal Météorologique, Centre du Physique du Globe in Dourbes, Belgium, a network of 15 repeat stations for measurement of the geomagnetic field in the Republic of Macedonia was created. For the first time since independence, all elements of geomagnetic field were determined <...>
Geomaterials are defined as ‘processed or unprocessed soils, rocks or minerals used in the construction of buildings or structures, including man-made construction materials manufactured from soils, rocks or minerals’ (Fookes, 1991). The definition deliberately includes manmade materials such as bricks or cement but excludes allied engineering materials whose manufacturing is more extensive, such as steel and synthetic paints.
Geomathematics provides a comprehensive summary of the mathematical principles behind key topics in geophysics and geodesy, covering the foundations of gravimetry, geomagnetics, and seismology. Theorems and their proofs explain why physical realities in geoscience are the logical mathematical consequences of basic laws.
The process commonly called going underground has been very well observed recently around the world. In short it means rather rapidly developing transference of numbers of even highly civilized human activities to the underground space. Geosphere, having been traditionally used as source of energy and raw materials, has now become the space where any anthropogenic activity could be placed and realized.
“Geomechanics and Geodynamics of Rock Masses” contains the contributions to the International European Rock Mechanics Symposium EUROCK-2018 (Saint Petersburg, Russia, 22–26 May 2018), and covers all high-tech solutions and advanced engineering developments in the field of geomechanics, from theory to application.
“Geomechanics and Geodynamics of Rock Masses” contains the contributions to the International European Rock Mechanics Symposium EUROCK-2018 (Saint Petersburg, Russia, 22–26 May 2018), and covers all high-tech solutions and advanced engineering developments in the field of geomechanics, from theory to application. Taking into account the rapid growth of industry requirements, there is an obvious need to strengthen research activities maximally, to provide professional assessment and build science-based predictions in various industrial sectors to ensure the economy running and the state development. <...>
The first international workshop on soil crushability was held in Sheffield, U.K. on September 1997 and was the origin of a subsequent series of meetings starting with the “International Workshop on Soil Crushability” IWSC’99 atYamaguchi University in Ube, Japan on July 1999. As a result of these workshops, the research area widened from soil crushability to a re-assessment of fundamental aspects of soil mechanics theories using micromechanics.
This paper presents an experimental investigation on contact behaviors of idealized granules which are bonded together with cement. First, by using the specimen preparation devices, two aluminum alloy rods with the same size are glued together by cement with the cement water ratio 0.34.
