The study presents geologic investigation of Yemen and the Gulf of Aden with a special focus on geophysical, seismic, tectonic and topographic mapping performed by the integrated approach of QGIS and GMT scripting. Cartographic visualization is crucial in geologic analysis, data processing and prognosis of mineral resource prospects. The region of Yemen and Gulf of Aden was formed as a result of Arabian and African plates movements and still tectonically active. Besides, the Gulf of Aden contains mineral resources of hydrocarbons which makes this region actual for investigation. The IRIS database on earthquakes was used for visualization of the magnitude of submarine earthquakes in the Gulf of Aden for the period of 2007-2020. The paper presents 6 new thematic maps for the region of Yemen and Gulf of Aden. The research presented an analysis of correlation between the geological, topographic and geophysical settings. Through combined approach of cartographic high-resolution data visualization and geologic analysis, this paper contributed to the regional geological studies of Yemen, Gulf of Aden and the Middle East.

Rain attenuation at Ka-band is a severe phenomenon that drastically impairs satellite communications at these frequencies. Several adaptive compensation techniques have been elaborated to counteract its effects and most often applied one at a time. The present paper proposes the contemporary exploitation of different techniques in a combined approach. Such an integrated approach is thoroughly analyzed in a simplified scenario and will be shown to achieve a very effective solution, making the Ka-band spectrum fully available for broadband satellite applications and network-centric systems.

The expediency of using the profile method of analysis for assessing the influence of technological factors on the quality of beer has been established. The characteristics for the evaluation of beer quality by the profile method are chosen. The results obtained using the profile method give a more complete picture of the properties of beer than the results of the scoring method. Each of the samples was analyzed and studied. The results of analysis of such criteria as aroma, flavor, appearance and physicochemical parameters are demonstrated on profilograms. Estimation of flavor is the most difficult, since this concept includes a complex sensation of taste, aroma and consistency, determined in the oral cavity. To confirm the organoleptic properties of the «body» of the best sort of beer, rheological analysis data were presented. Such an integrated approach will allow fully studying the properties of a low-alcohol beverage and clearly demonstrating the advantages of a profile method of analysis.

Arab countries face two major challenges resulting from increasing competition from the rest of the world and persistent reliance on mineral resources for their growth. At the same time, sustainable development is increasingly becoming a major concern for world development. In this respect, and from a sustainability point of view, knowledge economy opens up new and more accessible opportunities through the ‘substitution' of physical resources by immaterial resources. This situation raises two fundamental questions: the first one relates to the opportunity of ensuring sustainable development while the knowledge base remains rather weak and policies often short-sighted. The second one is how an integrated approach based on knowledge can strengthen existing knowledge bases and create new ones to further sustainable development. Looking at a sample of advanced countries and Arab countries, this chapter argues that sustainability of growth rests fundamentally on the capability of properly harnessing knowledge.

Abstract. Australian terranes concealed beneath Mesozoic cover record complex Precambrian tectonic histories involving a successive development of several Proterozoic to Paleozoic orogenic systems. This study presents an integrated approach combining K–Ar, 40Ar–39Ar, and Rb–Sr geochronology of Precambrian authigenic illites from the recently discovered Millungera Basin in north-central Australia. Brittle deformation and repeated fault activity are evident from the sampled cores and their microstructures, probably associated with the large-scale faults inferred from interpretations of seismic survey. Rb–Sr isochron, 40Ar–39Ar total gas, and K–Ar ages are largely consistent indicating late Mesoproterozoic and early Proterozoic episodes (~ 1115 ± 26 Ma, ~ 1070 ± 25 Ma, ~ 1040 ± 24 Ma, ~ 1000 ± 23 Ma, and ~ 905 ± 21 Ma) of active tectonics in north-central Australia. K–Ar results show that illites from fault gouges and authigenic matrix illites in undeformed adjacent sandstones precipitated contemporaneously, indicating that advection of tectonically mobilised fluids extended into the undeformed wall rocks above or below the fracture and shear (fault gouge) zones. This study provides insight into the enigmatic time-space distribution of Precambrian tectonic zones in central Australia, which are responsible for the formation of a number of sedimentary basins with significant energy and mineral resources.

Research subject. The Savabeisky sulfide copper-nickel ore occurrence, located in the central part of the Khengur (Central Pay-Khoy) gabbro-dolerite complex of the Pay-Khoy, within the Yugorsky Peninsula, located in the Far North-East of the European part of Russia, in the Arkhangelsk region, between the Barents and Kara Seas.Materials and methods. Samples of copper-nickel ores with noble metal mineralization were studied. Palladium tellurides and bismuthtellurides were characterized using optical and scanning electron microscopy, electron backscatter diffraction (EBSD), X-ray structural analysis and Raman spectroscopy.Results. Bismuthtellurides in the Paykhoysko-Vaigach-Yuzhnonovozemelskiy region – michenerite, merenskyite and unidentified palladium telluride of the kotulskite–merenskyite series with crystal formula Pd2(TeSbBi)3 – were found for the first time. The unit cell parameter of Pay-Khoy michenerite was calculated using X-ray diffraction analysis data: a = 6.638(2) Å. According to Raman spectroscopy, the palladium tellurides and bismuthtellurides of the Savabeisky ore occurrence were distinguished into 4 groups: Sb-kotulskite (does not contain Raman-active modes), unnamed PGM Pd2(TeSbBi)3 (bands in the range 95–103, 121–126 cm–1, obtained for the first time), Sb-merenskyite (band 126–135 cm–1), michenerite (bands with maxima 100 and 116 cm–1, obtained for the first time). The Kikuchi lines for michenerite and the mineral of the kotulskite–merenskyite series were obtained by the EBSD method.Conclusions. The diagnosis of palladium tellurides and bismuthtellurides is a rather complicated problem (wide variations in compositions, low hardness, small size, thin intergrowths of several individuals, the presence of impurities, etc.) affecting the determination of their mineral form and requiring an integrated approach. The Raman spectra of michenerite and unnamed PGM can be used as standards for the rapid identification of their natural forms, in contrast to EBSD, which requires improved sample preparation. The relatively high content of antimony in the ore minerals and noble metals minerals at the Savabeisky ore occurrence is the antimony metallogenic specificity characteristic of the entire Uralsko-Novozemelskiy province.

Nowadays small and medium sized enterprises have become increasingly important in contribution to job creation and economic growth both in national and European level. Considering the rapidly and continuously changing business environment, due to the impacts of globalization and concentration, staying competitive is a great challenge for companies in the 21st century, especially in fashion retail sector. The current paper is intended to map the current situation of the sector—focusing primarily on SMEs—through the extensive literature review; and provide a better understanding of sector-specific competitive factors in fashion industry. The research methods are the analysis of different related articles, reports and other scientific literature sources, in-depth interviews and questionnaire survey. The survey was validated by confirmatory factor analysis, data were analyzed and evaluated through PLS-SEM model. The main findings of the study show that the most important competitive factor is the compliance with consumer needs. Furthermore, the research also points out that SME sector lag behind chains, thus, they need to focus more on better understanding and meeting consumer expectations. In this activity, it would be useful if they received EU and domestic support for educational assistance.

Subject. As the Russian regions establish their socio-economic cooperation, they promote and advance their socio-economic development. Currently, the integration of three Siberian regions underlies the Yenisey Siberia, a major investment project. The integration is intended as a set of activities to explore mineral resources and allocate investment funds, involving inner reserves of the regions, thus unavoidably raising their socio-economic position. Objectives. In the study, I examine aspects of establishing the Yenisey Siberia, a cross-regional comprehensive integration and investment project. Methods. Research is based on methods of statistical analysis, data collection and processing. Results. I overview key socio-economic differences of the parties to the integration project and suggest using a model for the cross-regional integration of three Siberian regions with reference to goals and objectives of the Yenisey Siberia. Conclusions and Relevance. Natural and mineral resources of the area (Tyva, in this case) are the main driver of integration ties within an underdeveloped region, while coal mining appears to be a cornerstone for foreign trade ties. Driving the establishment of integration ties of Tyva, coal also streams fiscal revenue to the regional budget. Furthermore, the local potential is found to be insufficiently used for purposes of cross-regional and integration ties with other constituent entities of the Russian Federation.

This paper aims at clarifying the determinants that promote the community-based renewable energy development in Japan, with a special focus on micro and small hydropower. This paper analyzes a case study of the social enterprise that was established by the local residents and farmers in the Gokase Township, the purpose of which is to install and develop community-based renewable energy. To analyze the case study, we adopt the framework of the Landcare approach. The Landcare approach can be characterized by the following guiding principles: (1) a strong community initiative guided by local residents and primary producers; (2) a focus on local problems; (3) a holistic and integrated approach to tackling problems; (4) stress on community well-being; and (5) partnership and networking. There are similarities between the Gokase Research Institute of Renewable Energy (GRIRE) and Landcare in that they both focus on local issues that can be tackled by local citizens and take a holistic approach that includes not only hydropower development but also improvement in community well-being. This paper examines the fitness of each principle and reveals that all of them fit fairly well with the case of micro-hydropower development in Gokase. This implies that micro-hydropower development in Gokase can be qualitatively evaluated as sustainable from the perspective of Sustainable Development theory.

The purpose of the article is to analyse the economic growth of Sub-Saharan African countriesin the last decades, with special focus on the period 2000-2009. Economic development in Africa has been mostly positive in recent years with growth pace binge moderate and steady. However, significant differences exist between specific countries, stemming from abundance of mineral resources, location, size of the population or policy of central government. Countries which managed to introduce deep structural reforms, improve the investment climate, diversify output and exports as well as actively searched for new trading partners outperformed. Countries economy which is purely based on exports of crude oil reported also good economic performance,. However influx of investments there as well as general economic development is constrained by risk of the fiscal destabilization, which sudden plunge in commodity prices could originate. In our research we focused on the following growth indicators: GDP, savings rate, FDI, foreign trade and external aid.
