The modern stage of development of symbiogenetics, a biological discipline that addresses the formation of super-species genetic systems, is associated with the study of molecular mechanisms and environmental consequences of combining the hereditary factors of prokaryotes and eukaryotes into functionally integrated symbiogenomes, which, as partners lose their ability to autonomous existence, are transformed into structurally integrated hologenomes. The loss by intracellular symbionts of eukaryotes of their genetic individuality, determined by the ability to independently maintain and express the genome, representing a key step in symbiogenesis which results in the transformation of bacteria into cellular organelles. Genetic reconstruction of symbiogenesis provides the broad prospects for its artificial reproduction aimed at the synthesis of new organisms and biosystems possessing the predetermined sets of practically significant features.

The issues of determining the estimated cost of capital construction projects with the involvement of Federal budget funds at the stage of development of project documentation, during verification of the accuracy of determining the estimated cost and the initial (maximum) contract price are considered. On the basis of the assessment of amendments to urban planning legislation for the purpose of implementing a state contract by the contractor ( based on the results of competitive procedures or without competitive procedures by decision of state authorities), the procedure for forming the estimate as part of a state (municipal) contract, the price of which is firm, is presented. For the purpose of mutual settlements between the customer and the contractor for the work performed, the formation of primary accounting documentation, as well as for checking the work performed by regulatory authorities, an example of drawing up an estimate of the state (municipal) contract on the basis of grouping costs according to structural elements and complexes of work is given. The result of the research conducted was the development of regulations and the formation of criteria for their practical application by state bodies, institutions, organizations and other participants in the investment-construction process, as well as recipients of budget funds, who perform the functions of the state (municipal) customer, developer and technical customer.

Vision is the science that informs us about the biological and evolutionary algorithms that our eyes, opticnerves and brains have chosen over time to see. This article is an attempt to solve the problem of colour to grey conversion, by borrowing ideas from vision science. We introduce an algorithm that measures contrast along the opponent colour directions and use the results to combine a three dimensional colour space into a grey. The results indicate that the proposed algorithm competes with the state of art algorithms.

The article analyzes problems of the Russia forest complex development related to social, environmental and infrastructure issues, the solution of which is impossible without state participation. The reasons of the poor adaptation of the forest complex market economy to long development periods, as well as the environmental consequences of economic activity, including environmental pollution, depletion of natural resources, loss of biodiversity and damage to public health, are considered. The analysis of the forest complex market economy features is made on domestic and foreign examples, a serious shortcoming of which is the isolation of the investment payback process from the chosen economic development direction. Forest rejuvenation in this way leads to a decrease or even loss of the forests biospheric properties to regulate the surface runoff of atmospheric precipitation and the formation of groundwater reserves. It is known, that in the forests of the European part of Russia have been accumulated large reserves of semi-subsistence conifer and hard wood. It is shown that to involve it in use it is necessary to change the principles of annual use calculations and to actually re-develop the regulatory framework for the intermediate use of forest wood resources. Four forest management units in the forest economy of the forest complex were identified: state forest management and implementation of medium-term and long-term planning of all types of work in forests, taking into account materials of the state forest inventory and assessing the state and trends in the development of domestic and foreign timber markets; protection and protection of forests from fires and other adverse natural factors (insects, fungi, pollution); carrying out planned logging with the differentiated use of all types of wood and the organization of reforestation taking into account the diversity of growing conditions and the possibilities of using the lands of the state forest fund of Russia. It is advisable to create economic mechanisms to stimulate the activities of all enterprises and institutions of the Russia forest complex for the transition to new environmentally sound technologies in the forest. A flexible economic mechanism is needed to include forest management costs in the cost of harvested wood in order to restore the ecological, economic, social and cultural properties of forests.

Parliamentary Regimes

The article defines the features of the process of forming the research tradition of studying the institute of parliamentarism as a mechanism for the formation of democracy. It is established that parliamentarism acts as one of the varieties of the regime of functioning of the state, to which the independence of the representative body from the people is inherent, its actual primacy in the state mechanism, the division of functions between the legislative and executive branches of government, the responsibility and accountability of the government to the parliament. It is justified that, in addition to the regime that fully meets the stated requirements of classical parliamentarism, there are regimes that can be characterized as limited parliamentary regimes. The conclusions point out that parliamentarism does not necessarily lead to a democracy regime. At the first stage of development of statehood, it functions for a long time in the absence of many attributes of democracy, but at the present stage, without parliamentarism, democracy will be substantially limited. Modern researchers of parliamentarism recognize that this institution is undergoing changes with the development of the processes of democracy and democratization. This is what produces different approaches to its definition. However, most scientists under classical parliamentarianism understand such a system, which is based on the balance of power. This approach seeks to justify limiting the rights of parliament and strengthening executive power. Keywords: Parliamentarism, research strategy, theory of parliamentarism, types of parliamentarism

The Moment

The article presents the results of the first research on artificial reproduction in industrial conditions of the endemic, narrow-areal subspecies of Brachymystax lenok Savinovi, which lives in lake Markakol, East Kazakhstan region. The indicators of the heat sum characteristic for each stage of development, the rate of development and growth of the Markakolsky lenok from the moment of pre-breeding to late juveniles are described. To develop technological approaches for artificial fish reproduction, one of the most important points is to determine the optimal conditions for each stage and assess the risks (loss of fish products). At the stage of insemination and transportation of eggs to the place of incubation, the loss was 50 %. The largest losses of fish products were registered during the incubation stage. The most painlessly passed the period of holding and lifting on the float, where the loss was only 3 %. When growing pre-larvae and larvae in the pool, the daily waste did not exceed 1 %. Small-sized animals that were unable to adapt to artificial feeds fell into the waste. Losses during this period amounted to 15 % of the previous stage. In General, the yield of juveniles from the moment of fertilization to the end of the experiment was 16 %. The crucial factor in the development and growth of Lenok Markakolosky is the temperature regime. For the period of embryonic development, the most favorable water temperature is 7–8 °C. From the moment of hatching, the water temperature must be increased to 10–12 °C, and the optimal temperature for the cage growing of fingerlings varies from 12 to 14 °C.

First Offers

This essay is in four parts. The first offers a critique of James Elkins and Michael Newman’s book The State of Art Criticism (Routledge, 2008) for what it tells us about art criticism in academia and journalism and feminism; the second considers how a gendered analysis measures the “state” of art and art criticism as a feminist intervention; and the third, how neo-liberal mis-readings of Linda Nochlin and Laura Mulvey in the art world represent feminism in ideas about “greatness” and the “gaze”, whilst avoiding feminist arguments about women artists or their work, particularly on “motherhood”. In the fourth part, against the limits of the first three, the state of feminist art criticism across the last fifty years is reconsidered by highlighting the plurality of feminisms in transnational, transgenerational and progressive alliances.
