Based on a package of modern analysis methods, the influence various acids and energy effects morphology, elemental composition, structural chemical transformations mineral surface, efficiency eudialyte concentrate leaching was studied. The mechanism optimal conditions specific features destruction rock minerals extraction zirconium REE under acids, powerful nanosecond pulses, dielectric barrie...

Abstract. On 6 February 2023, two major earthquakes occurred in the East Anatolian Fault Zone (EAFZ) of Türkiye. The EAFZ forms east border Plate. magnitude 7.7 and 7.5 Kahramanmaraş – Türkiye Earthquakes that struck southern resulted common destruction 11 provinces region. Total main fault segments ruptured during earthquake sequence on approximately 400 km surface rupture occurred. life losse...

The paper considers the relevance of research, indicated by authors in title article. As a result studies carried out, it was found that overturning torque cutting forces occurs as imbalance system during destruction rocks actuating device geokhod. It revealed value critical is influenced two force factors; this projection resistance soil to on plane perpendicular axis rotation, well total mome...

The strengthening of a coastal zone considers complex hydrodynamic factors (waves, currents, wind and materials carried by them), climate, rock stability, sedimentation eustatic fluctuations at sea level. terrace on which the urban structures Nessebar are located is formed almost horizontal Miocene limestone sandstones, marl lime stones clays. It limited steeply abraded coast, subjected to dest...

This paper deals with the statistical analysis of the uniaxial compressive strength and of the elastic modulus of jointed rock masses under different confining pressures. Properties of the rock masses with different joint fabric, with and without gouge have been considered in the analysis. A large amount of experimental data of jointed rock masses from the literature has been compiled and used ...

—The detection of materials or devices for nuclear or radiological weapons of mass destruction is fundamentally important to national safety and security, and detection technologies are necessary both to nd and to verify the location of those materials or devices. To ful ll this task, this paper presents a statistical approach to the detection and location of radioactive target via wireless sen...

One of the principal concerns in graduate admissions is how future performance in graduate studies may be predicted from a candidate’s undergraduate achievements. In this study, we examined the statistical relationship between B.Sc. and M.Sc. achievements using a dataset that is not subject to an admission-induced selection bias. Our analysis yielded three insights. First, we were able to expla...

In the first part we show a counterexample to a conjecture by Shelah regarding the existence of indiscernible sequences in dependent theories (up to the first inaccessible cardinal). In the second part we discuss generic pairs, and give an example where the pair is not dependent. Then we define the notion of directionality which deals with counting the number of coheirs of a type and we give ex...

In December 2008, the US Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism, released a report, World At Risk. The Report points to the fact that, not only is the use of a weapon of mass destruction in a terrorist attack before the end of 2013, more likely than not, but also to the fact that terrorists are more likely to be able to obtain and use biological ...

Mining and its related activities have always resulted in changes the environment these can vary from one area to another. As a result of mining, several types be distinguished: destruction land existing vegetation, terrain topography, modification air quality, surface groundwater as well change geotechnical conditions rock. Environmental impact mining has been public concern. There is widespre...
