    The effect of alkaline treatment of shrimp chitin on the molecular weight, the degree of deacetylation and degree of crystallinity of the resulting chitosan is studied. The viscosity of chitosan solutions from repeatedly deacetylated chitin is studied. It is shown that repeated treatment of chitin/chitosan with alkali causes the destruction of polysaccharide macromolecules. After four-time deacetylation and one-time deacetylation of chitin/chitosan for four hours, the molecular weight of the polysaccharide decreases by ten times. The maximum degree of chitosan deacetylation under experimental conditions was 92.0 -92.5%. The diffractograms of chitin and chitosan from the Northern shrimp are of the form typical for samples containing an amorphous phase in addition to a crystalline phase. The degree of crystallinity of chitin from Northern shrimp was 40.8%, of chitosan samples after one-, two-, and three-time deacetylation was 62-65%. For a sample of chitosan obtained after four-time deacetylation, recrystallization, and drying in a freeze dryer, the degree of crystallinity is close to the degree of crystallinity of shrimp chitin. The investigated acetic acid chitosan solutions with a concentration of 5% (wt.) and the chitosan molecular weight of 250, 160 and 130 kDa in their rheological properties are liquid-like non-Newtonian systems, their viscosity decreasing with increasing shear stress. After four-time deacetylation of chitin, the viscosity of chitosan solutions practically does not change with increasing shear stress, which apparently can be due to a significant decrease in the molecular weight of chitosan under these conditions

    The subject of the article is the item of what is the interrelation between such management frameworks as strategic planning and public-private partnership (PPP). Development of PPP seems relevant especially for particular regions of the country as such a concept allows the salvation of important socio-economic issues of territory and economizing budget resources at the same time. Aside from that, PPP might serve as a tool for stable region development. However, this requires carrying out a purposeful policy on developing public-private partnerships, which is going to be worked on and reflected in regional strategic plans. Within the framework of this deed based on specific Russian region experience, the research is taking place, how exactly perspectives of development and usage of PPP are reflected in strategy documents, and how this is being reflected on the development level of this economical concept. The basis of the study includes such methods as, compilation analysis of regional regulatory legal acts, score-based document-benchmarking study, and integral estimation of PPP development level in Russian Federation regions. The study results allowed estimation of Russian Federation regions experience, to highlight some issues obstructing PPP development, and to suppose a group of recommendations, and using them practically will allow for more accurate and complete securing perspectives of PPP development in regional strategic plans. Moreover, this in turn, will allow making PPP a more effective tool not for investments attraction only, but also for achieving stable development

    Goal: The study aims to assess the level of development of the information society in the regions of Russia. The use of digital technology is gaining relevance in many areas and dramatically simplifies the life of a modern person. This has become the basis for the formation of the information society, in which information and digital technology contribute to the emergence of qualitatively novel socio-economic conditions of life. The study of the information society is carried out mainly with regard to each state, while the study of its formation and development in individual regions of the country remains less researched. In this connection, the present study attempts to examine the dynamics of the development of the information society in various regions of Russia. Methods: The study is based on the mathematical method of calculating normalized indicators, the calculation of integral scores, the ranking and comparative analysis of data, and the method of classification. The information society in the selected regions of Russia is examined in terms of the dynamics of change, the status of its individual aspects, and the overall level of development achieved. Results: The results of the assessment and comparative analysis lead to the following conclusions. The development of the information society in each region of Russia has its own specifics. It is extremely difficult to identify common universal trends or patterns of its development in different constituent entities of Russia. Conclusion: In this context, of particular relevance is the development of a regional, rather than national, digitalization policy. The main directions for a regional policy should be determined in accordance with the peculiarities of the dynamics of information society development in the specific socio-cultural and economic environment of the region. Furthermore, it is crucial to consider the key issues and overall state of the region's information society achieved to date compared to other territories

    The methods of controlling the consequences of the influence of manmade geomechanical processes caused by the extraction of hydrocarbons from the subsurface in the fields under development are considered. The possibilities of methods from the standpoint of separate determination of spatial and temporal quantitative parameters characterizing the deformed state of the skeletons of reservoirs and host rocks, the entire thickness of the rock mass above the deposit in an uneven field of compressive stresses and deformations of the earth’s surface are shown. The inconsistency of methods of classical repeated leveling, geodetic positioning and traditional radar interferometry in connection with the low level of representativeness of their results is noted. scientific novelty lies in the development of ways to improve the effectiveness of the method of radar satellite interferometry. As a result, the conditions for the effective use of radar satellite interferometry on the basis of a network of stationary points which coincide with the points of the leveling network method of spot geodetic sounding of deformation processes in the oil and gas fields under development have been determined and characterized

    Systems engineering and design of a Mars Polar Research Base with a human crew

    Mars Polar Ice caps have been known ever since they were first observed by Cassini. Robotic exploration mis- sions, starting with Mariner 9, have confirmed that they are composed of water ice. During later missions, instruments such as Mars Global Surveyor's MOLA have established a detailed topography and have estimated their depth at about 3 km in the thickest part, while detailed internal structure has been investigated by MARSIS from Mars Express and SHARAD from the Mars Reconnaissance Orbiter. This analysis proposes to establish a base near North Polar Layered Deposits to investigate Mars' climate, hydrological processes and to test for possible traces of life. The objectives of the mission are to sustain a crew for nine months on the surface of Mars, near the North Pole, and to bring the crew back to Earth safely. During the surface mission, the crew will drill and analyze Polar Layered Deposits in ice samples. Furthermore, because the North Polar region provides an easy access to water ice, this area has the potential of sustaining a long-term human presence. The Mars Polar Research mission shall therefore prepare for long term missions, spanning over multiple crew generations. Indeed, longer duration missions and larger crews should be facilitated by this first mission. This paper describes a mission design for a Mars Polar Research base using systems engineering approach and scenario testing. The goal of the work is to establish a strategy composed of various technologies that have been selected accordingly. The requirements related to crew composition, human physiology and psychology adaptation, quality of com- munication, challenges and prospects of advancing science, as well as optimum habitat design and its usability, are derived and compiled into mass, volume, data and power consumption. A design for the base and mission scenario is also proposed. Given the identified requirements, possible technologies for life support systems, radiation protection, in-situ propellant production, thermal control, air pressure difference compensation and availability of power are discussed and solutions to focus on are recommended. Furthermore, the requirements for a long-term mission preparation are also identified and solutions to include in a first Mars mission with crew are recommended. In conclusion, approximately 110 metric tons and 160 kW are required to enable a Mars Polar mission with a human crew. A two-phase mission is recommended for enabling the testing of key in-situ resource utilization technologies allowing to minimize mass, while ensuring the security of the crew. The use of optimal payload and fairing, a Mars orbit crane system and deployable structures are recommended. Finally, in pre- paration for a long-term presence of humans on Mars, including in-situ testing of key technologies enabling the production of consumables facilitating autonomy from Earth is suggested. The consumables that have been identified as not being able to be tested before a first crew is sent to Mars are food and energy production. These developments may serve as priorities for current Mars settlement programs
