Situation and value of the African continent on the economic and social cardmap of the world dynamically changes and will continue to change throughout all the 21st century with strengthening of the Africa positions in the world. In Russia all the complex of threats and problems which arise owing to political and economic transformation of Africa is not adequately estimated. The scientific literature on economic security issues presents an expanded set of internal and external threats to the national economy that goes beyond the traditional areas of the shadow economy, corruption, economic crime and related segments, including the internal economic stability of the national economy and inter-country competition, the quality of state strategic management, studies of the specifics of ensuring economic security in the conditions of the sixth technological order, intercultural communication and their impact on the economic relations between countries, etc. Incomplete use of such approach to strategy for the countries of Africa creates additional threats and risks for Russia. An analysis of security problems in Africa revealed that studies of economic security in the context of African development trends in Russia are conducted in an unsatisfactory volume, not always taking into account the results of new developments in the field of ensuring economic security. Even the large shifts happening on the African continent, forecasts of this dynamics sometimes are poorly known to experts of a profile of economic security, and many experts of an economic profile including working in the African subject often do not accurately distinguish problems of “economic cooperation” and “the Russian – African relations”, on the one hand, and “economic security of Russia” – with another. In this regard the new scientific problem is proved: need for deeper analysis of trends of economic and social development in Africa as an important component of a system of ensuring national economic security of Russia in the current period and in the future into account the new developments in the sphere of economic security. The main directions of activating scientific research and concentration of practical efforts to increase national economic security, neutralize threats and reduce risk for Russia in the designated context are formulated.

In 2011, Miss Sahhara, a transgender woman from Nigeria with UK refugee status, was crowned First Princess at the world’s largest and most prestigious beauty pageant for transgender women—Miss International Queen. The then Cultural Minister of Nigeria when contacted for comment responded that if she was transgender, she could not be Nigerian, and if she was Nigerian, she could not be transgender—a tacit denial of her very existence. In recent years, LGBT people “fleeing Africa” to the “Global North” has become a common media trope. Responses to this, emanating from a variety of African voices, have provided a more nuanced reading of sexuality. What has been absent from these readings has been the role of gender expression, particularly a consideration of transgender experiences. I understand transgender refugees to have taken up “lines of flight” such that, in a Deleuzian sense, they do not only flee persecution in countries of origin but also recreate or speak back to systems of control and oppressive social conditions. Some transgender people who have left, like Miss Sahhara, have not gone silently, using digital means to project a new political visibility of individuals, those who are both transgender and African, back at the African continent. In Miss Sahhara’s case, this political visibility has not gone unnoticed in the Nigerian tabloid press. Drawing on the story of Miss Sahhara, this paper maps these flows and contraflows, asking what they might reveal about configurations of nationhood, gender and sexuality as they are formed at both the digital and physical interstices between Africa and the Global North.

The richest diatom complexes have revealed due to the study of glacial-marine sediments sampled in the Fisher Massif (Prince Charles Mountains, East Antarctica) during 52nd and 53rd Russian Antarctic Expeditions (Polar Marine Geol. Survey Expedition) in 2006/07 and 2007/08. Three diatom complexes are distinguished according to different palaeoecological conditions: the planktonic one is located in the basis of the outcrop, while mixed planktonic-benthic and benthic ones being located above. The planktonic diatom complexes are dominated by two oceanic species Actinocyclus ingens (up to 8%) and Denticulopsis simonseni (up to 80%). There are 15 planktonic algae, e. g. Eucampia аntarctica, Fragilariopsis spp., Rhizosolenia spp., Rouxia antarctica, Podosira antarctica sp. nov., Stellarima microtrias; and also unknown and non-described benthic diatoms Achnanthes sp., Cocconeis spp., Rhabdonema (s. l.) spp. and Synedra (s. l.) spp. Detailed data on morphology and taxonomy of 10 centric diatoms are presented, including 3 newly described species.
