The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.

The correlation between the development of the world’s population is examined and, in connection with this, the expansion and development of the list of problems necessary for solving the problems of life support for a growing population is considered. It is indicated that the solution of these problems will contribute to the consumption of energy resources, which requires the identification and implementation of alternative sources. It was noted and justified that for this purpose the most promising in this direction around the world are biomass, which are involved in the production of renewable fuel bioenergy based on them. The classification and possibilities of biofuel compositions and the technology of thermochemical production of them and on their basis thermal energy, electricity and the development of bio-based chemicals and materials from biomass are given. The modularity of production was confirmed, including the collection, conversion, energy supply, classification and processing of the remains - products of these stages of production. A list of factors that negatively affect the social, economic and environmental conditions is formulated.

The first person to use the term “museology” in the Czech environment seems to have been Mr. Kliment Cermák, teacher and museologist, who for the first time formulated a need for special education to be provided for museum workers in his article Education in Museology from 1901 published under his editorship in the Bulletin of Czech & Slavonic Archaeological and Museum Association. His publication activities were continued by V. V. Jenícek in the magazine “Czech & Slavonic Museum Annals” between 1902 and 1910 and by Albín Stocký in the magazine “Museum Horizon” published between 1925 and 1928. In Slovakia, there were A. Kmet’ and F. Sasinek, and later P. Kri ko, M. Rybecký, A. Gregorová and M. Lalkovic, standing at the beginning and formation of museology. This generation, and for the most part also the following generation, were on a level comparable with the European elite but they published mainly in the Czech language, therefore they remained more or less hidden from the rest of the world. Museology undoubtedly has a long tradition in Central Europe and this paper aims to reflect the present status and key issues in the environment of the former Czechoslovakia.

The article describes the current economic trends development services sector through the effective economic development paradigms prism: from industrial-oriented to service-oriented, when it’s impossible to provide the high-tech and knowledge-intensive industries accelerating development, without the consumer industries complex of public goods and services providing development. The life quality improving and human interest to the new impressions had provided the growth of committed travels. Under the world economics consumer psychology changes, from the second half of the XX century, the world has witnessed the rapid development of global and national tourism markets. However, the Russian national market of tourist services lags behind the world´s leading tourism industry and shows a slow growth. The huge territory, underdevelopment supporting infrastructure, lack of tourist class hotels lead to the fact that the development of the tourism sector in the country is extremely uneven and has a point character. Moreover, in 2014 the Russian market of tourist services was recognized as opaque. A large number of limiting factors hinder the development of domestic tourism in Russia, in this regards, the international tourism in our country is developing primarily with a focus on travel. At the science point of view, the management decisions in any economics sphere, even if in tourist market developing, have to be based on the current status and forecasts of market development study and analysis. Due to this reasons, the considered in this article information about current trends in the Russian national tourism market has a high relevance.

Since 1991, researchers from approximately 45 nations have participated in eight International Conferences on Serpentine Ecology (ICSE). The ICSE conferences are coordinated by the International Serpentine Ecology Society (ISES), a formal research society whose members study geological, pedological, biological and applied aspects of ultramafic ecosystems worldwide. These conferences have provided an international forum to discuss and synthesise multidisciplinary research, and have provided opportunities for scientists in distinct fields and from different regions of the world to conduct collaborative and interdisciplinary research. The 8th ICSE was hosted by Sabah Parks in Malaysia, on the island of Borneo, and attracted the largest delegation to date, 174 participants from 31 countries. This was the first time an ICSE was held in Asia, the region that hosts some of the world’s most biodiverse ultramafic ecosystems. The presentations provided a cross-section of the current status of research in all aspects of serpentine-biota relations. In this Special Issue of Australian Journal of Botany, which encompasses two double issues (1–2 and 3–4), we have compiled a selection of papers from among the oral and poster presentations to provide insights into recent advances in geoecological and applied studies of serpentine habitats worldwide.

The recent trends in the world output of titanium-containing concentrates and titanium sponge – intermediate product in the production of metallic titanium – has been studied. The differences in the dynamics of these indicators have been found due to the fact that titanium-containing concentrates are used not only as raw materials for the production of titanium metal. The clusters of the world's major producers of titanium-containing concentrates and titanium sponge have been identified. The range of factors potentially influencing the titanium sponge price dynamics has been studied; the independence of this dynamics from fluctuations in supply and demand and the price of raw materials has been shown. The results of activity of JSC “Corporation VSMPO-AVISMA” were analyzed. The study shows that the main factor determining the sales profit margin of the Corporation is the dynamics of the exchange rate; a quantitative assessment of the degree of such influence has been made.

the relevance of the paper is due to the search for alternative sources of raw materials for the construction industry, associated with the disposal of man-made waste. The novelty of the article is to identify the scien-tific laws of the influence of demolition waste on buildings and structures on the formation of the micro-structure of lightweight and heavyweight concrete. Concrete waste was prepared as both fillers of cement materials and fine aggregates, based on which concrete with high mechanical properties was created. The mix design was carried out from the point of view of geomimetics, in particular, taking into account the law of affinity of structures. The strength characteristics of concrete mixtures were investigated in accordance with EN 12390-3. In addition, the microstructural, morphological and thermal properties of the raw materials and concrete were determined during 28-day curing. For the first time, the dense microstructure of the com-posite was ensured, both with Portland cement products and with hydration, and, in part, with hydration products of previously unreacted clinker, whose minerals are present in concrete waste and are activated when they are crushed. The use of demolition waste of buildings and structures as a filler of cementing ma-terial when replacing Portland cement up to 20% allows to obtain better compressive strength of both heav-yweight and lightweight concrete.

Abstract. Background: Little is known about the role of resilience in the likelihood of suicidal ideation (SI) over time. Aims: We examined the association between resilience and SI in a young-adult cohort over 4 years. Our objectives were to determine whether resilience was associated with SI at follow-up or, conversely, whether SI was associated with lowered resilience at follow-up. Method: Participants were selected from the Personality and Total Health (PATH) Through Life Project from Canberra and Queanbeyan, Australia, aged 28–32 years at the first time point and 32–36 at the second. Multinomial, linear, and binary regression analyses explored the association between resilience and SI over two time points. Models were adjusted for suicidality risk factors. Results: While unadjusted analyses identified associations between resilience and SI, these effects were fully explained by the inclusion of other suicidality risk factors. Conclusion: Despite strong cross-sectional associations, resilience and SI appear to be unrelated in a longitudinal context, once risk/resilience factors are controlled for. As independent indicators of psychological well-being, suicidality and resilience are essential if current status is to be captured. However, the addition of other factors (e.g., support, mastery) makes this association tenuous. Consequently, resilience per se may not be protective of SI.

INTRODUCTION: India being the second highly populated nation in the world. HIV/AIDS has acquired pandemic proportion in the world. Estimate by WHO for current infection rate in Asia. India has the third largest HIV epidemic in the world. HIV prevalence in the age group 15-49 yrs was an estimate of 0.2%. India has been classified as an intermediate in the Hepatitis B Virus (HBV) endemic (HBsAg carriage 2-7%) zone with the second largest global pool of chronic HBV infections. Safety assessment of the blood supply, the quality of screening measures and the risk of transfusion transmitted infectious diseases (TTIs) in any country can be estimated by scrutinizing the files of blood donors. After the introduction of the blood banks and improved storage facilities, it became more extensively used. Blood is one of the major sources of TTIs like hepatitis B, hepatitis C, HIV, syphilis, and many other blood borne diseases. Disclosure of these threats brought a dramatic change in attitude of physicians and patients about blood transfusion. The objective of this study is to determine the seroprevalence of transfusion transmitted infections amidst voluntary blood donors at a rural tertiary healthcare teaching hospital in Chhattisgarh. MATERIAL AND METHODS: This retrospective study was carried out in Chandulal Chandrakar Memorial Medical College, Kachandur, Durg. Blood donors were volunteers, or and commercial donors who donated the blood and paid by patients, their families, or friends to replace blood used or expected to be used for patients from the blood bank of the hospital. After proper donation of blood routine screening of blood was carried out according to standard protocol. Laboratory diagnosis of HIV 1 and HIV 2 was carried out by ELISA test. Hepatitis B surface antigen was screened by using ELISA. RESULTS: A total of 1915 consecutive blood donors’ sera were screened at Chandulal Chandrakar Memorial Medical College, blood bank during study period. Of these 1914 were male and 1 female. The mean age of patients was found to be 29.34 years with standard deviation (SD) of 11.65 Years. Among all blood donors in present study, 759(39.63%) were first time donors and 1156(60.37%) were repeated donors. 1 patient was HIV positive in first donation group while 3 (75%) were positive in repeat donation group. 7 (38.9%) were HBsAg positive in in first donation group while 11(61.1%) were positive in repeat donation group. Two patients in first donation group had dual infection of HIV and HBsAg. CONCLUSION: Seropositivity was high in repeated donors as compared to first time donors. The incidence of HIV is observed to be 0.2% and that of HBsAg is 0.94%. Strict selection of blood donors should be done to avoid transfusion-transmissible infections during the window period.
