AbstractThe aim of the paper is to assess the applicability of a multi-objective biogeography-based optimisation algorithm in MEMS synthesis. In order to test the performances of the proposed method in this research field, the optimal shape design of an electrostatic micromotor, and two different electro-thermo-elastic microactuators are considered as the case studies.

Currently, the minerals’ extractive industries are going through a deep technological modernization, with a characteristic expansion of international exchange of knowledge and know-how. The unification of the equipment used in open-pit and underground mining, the global spread of advanced mining technologies increases the importance of the linguistic competencies of mining engineers. At the same time, the specifics of training mining engineers is the uniqueness of situations in the extraction and processing of mineral resources, which actualizes the case study method in the training of mining engineers. The paper provides a description of the term «case study» and its basic characteristics and principles of application. The content is based on the authors’ own experience of mining engineers in case studies while teaching English. Some examples of case studies for mining engineering students studying English are presented. The paper notes the effectiveness of implementing case study method and shows its benefits for introducing in the process of mining engineers training. In addition to listing positive effects of the method for developing skills necessary for competitive specialists such as critical thinking, problem solving, creativity, collaboration, etc., the authors mention possible problems that are likely to occur while using this method as well.

In this study, the CML model for resource depletion was updated based on the current status of the mineral resources and the characteristics of relevant statistics in China; and the characterization factors of resource depletion were determined for the majority of natural minerals which are most used in materials industry. Besides, case studies on iron and steel production (BF-BOF and EAF process) were carried out to demonstrate the valid of the modified and localized resource depletion model. The results show that in terms of category, the development of Chinese steel industry is mainly based on the depletion of the natural iron ore and fluorite. The results also show that for BF-BOF process, abiotic resource depletion potential (ADP) in 2012 is 5.26 times of that in 2004; and for the EAF process, ADP in 2012 is 23.6 times of that in 2004. Therefore, the information of ADP needs to be updated at intervals of time.

Aiming at overcoming the disadvantage of ignoring environment resources value loss caused by mineral resources exploitation in traditional GDP accounting, a new accounting method was put forward. Through analyzing the forms of environment damage caused by mineral resources development, the mine environment problem was divided into seven forms: natural landscape damage, vegetation destruction, geological disasters, air pollution, water pollution, solid waste pollution and noise pollution. Based on this classification system and general principle of value estimate for environment resources, the value loss indexes of each form were identified, and the calculation method for every index was put forward. As a result of the research, an accounting model that can be used for green GDP accounting relative to mineral resources exploitation was obtained.

This paper presents and discusses three case studies of scientific organizations involving geology, based on successive institutional models of geological surveys, namely: the "Geological Commission of Brazil", the "Geographical and Geological Commission of São Paulo", and the "Geological and Mineralogical Survey of Brazil". The issues linked to the exploitation of the land opened the way to the development of geological sciences in Brazil. Contrary to what one might expect, in view of Brazil's considerable mineral resources, the institutionalization of geology was linked more directly to agriculture rather than to mining. It was the interests of agriculture, especially those related to coffee planting, that influenced the direction of research and the results obtained.
