Development of an Extruded Potato Snack Using Recycled Materials

The study is aimed at solving the problem of snacks deficiency corresponding to the concept of a balanced diet. Snacks were made using rational process parameters using fish powder obtained from the fillet waste of protein-rich salmon and malt grains rich in dietary fiber. The composition of the recipe mixture was optimized through calculation and a series of experiments. In investigate took as calculated variables the starch and fat content in the recipe mixture and the biological value; as response variables, organoleptic properties and expansion coefficient. The result was an extruded snack, consisting of 79% of crushed dried potatoes, of 8% of fish powder and of 12% of malt grains, which, in comparison with similar snacks, has a higher biological value of 83%, an increased protein content of 14.5% and a dietary fiber value of 8.4 %, a reduced fat content of 1% and a reduced energy value of 340 kcal. The analysis of the quality indicators of the snack confirmed that this product satisfies the requirements for snacks in terms of physicochemical, organoleptic, microbiological and safety indicators. The developed potato extruded snack is targeted at different population groups and is a healthier alternative to potato chips

An overview of the latham’s snipe population in sakhalin, Eastern Russia

Latham’s Snipe (Японский бекас) Gallinago hardwickii was historically considered to breed mostly in Japan with a small proportion of breeding records in Russia. Since the 1950s, the species has been expanding its range northward and the current distribution of snipe encompasses most of the island of Sakhalin. At the same time, the species has experienced a breeding range contraction in Japan. During May 2019, opportunistic snipe surveys were conducted during a nine-day field trip of Sakhalin. Snipe were recorded either as incidental observations or during a 10’ point count. The highest numbers of snipe were found on the south-west coast of Sakhalin in the Tomarinskiy and Korsakovsky regions. All records were made in mosaic meadow-forest and modified grassland habitats, and none were obtained from forest or intact woodland. Comparison of these snapshot data to breeding surveys conducted between 1993 and 2012 demonstrate the species to be relatively widespread across Sakhalin, and in most areas not dominated by continuous forest. However, the conditions under which snipe breed successfully are more restricted than would be expected based on these broad habitat associations and numbers of displaying males. Agricultural intensification, spring burning of meadowlands and illegal shooting of snipe all reduce breeding success. While a significant proportion of the Latham’s Snipe global population appears to occur on Sakhalin (potentially as high as 18%), when considered in the broader context of species decline documented in Japan, it is likely that the global trend for this species is generally downward. © 2020, Australasian Wader Studies Group.

The Role of White-rot Fungi in Herbicide Transformation

Understanding herbicide transformation is necessary for pesticide development for their safe and efficient use, as well as for developing pesticide bioremediation strategies for contaminated soil and water. Recent studies persuasively demonstrated the key role of soil white-rot fungi in biotransformation of various anthropogenic environmental contaminants. However, often this common knowledge is not associated with specific metabolic processes of fungi and therefore cannot be transformed into specific recommendations for agricultural practice. The given review offers a systematic collection and analysis of the current knowledge about herbicide transformation by white-rot fungi at the cellular and molecular levels. Special attention is given to the role of oxidative enzymes such as laccases, lignin peroxidases, and manganese peroxidases in the biotransformation processes

The Image of Municipalities

Purpose of the study: The aim of this study is to investigate the image of municipalities and also to determine the things that give the city a positive image of the territory. Methodology: The theoretical and methodological basis of the study is the ideas and paradigms that were developed in the works of leading domestic sociologists, cult urologists, economists, and marketers. The applied individual methods include comparative analysis, typology, classification method, questionnaire, method of analysis of social factors and events Results: The Program of socio-economic development must be amended in the form of a subprogram for the formation of a positive image of the municipality of Chekhov, since today there are no projects or programs aimed at creating a positive image of the municipality to one degree or another, its popularization and perception among the local population and among tourists. Moreover, information support of the main assets of the municipality of Chekhov (information about the advantages of the territory, photographs and advertising leaflets) in social networks, the media, on the Internet, that is, marketing of historical and cultural heritage with a priority on the work of A.P. Chekhov Applications of this study: The formation of a favorable image is of fundamental importance primarily for residents of the municipality. It affects the creation and support of social optimism among the population, trust in the authorities and confidence in the future. Novelty of the study: The image of the municipality is formed from the priority elements of its structure and a set of certain factors of development and promotion of the territory. So, the novelty of this study is to asses this image in modern life

Composite building materials based on nanomodified cement systems

ABSTRACT: Introduction. This research work investigates the combined influence of nano-sized silicon dioxide (nano-SiO2 ), carbon nanotubes and surfactants on the structural and technological characteristics of cement compositions. Materials and research methods. The paper reveals the findings of a study on the effects of various dispersion techniques of carbon nanotubes (CNT) in surfactants, such as mechanical dispersion, ultrasonic treatment, and a combined method. It considers the uniformity of CNT distribution within the plasticizer and within the cement system, along with their impacts on the physical and mechanical properties of cement stone and concrete. Differential thermal and electron microscopic analysis of aqueous dispersions of carbon nanotubes and hardened activated nanomodified cement stone was carried out. Results and discussion. It has been experimentally proven that mixing nanotubes in dry cement does not allow them to be evenly distributed throughout the volume of the mixture. When using carbon nanotubes, the maximum effect is achieved when they are introduced into aqueous dispersions of plasticizers. The percentage of plasticizer was 1%, CNT 0,1% per 1 liter of water. The most effective method of dispersing carbon nanotubes in a plasticizer is a combined one. The results obtained were used in the preparation of cement stone and concrete compositions. Conclusion. The results show that complex additives consisting of nano-SiO2 and aqueous dispersions of carbon nanotubes have a positive effect on the physical-mechanical and structural-technological properties of cement stone and concrete. Graphic dependencies are shown indicating the effectiveness of using complex additives in the production of cement composite

Chemical and biological indicators for evaluation of Arctic soil degradation and its potential to remediation

In recent years, significant efforts have been made to accelerate the economic development of the Arctic zone, leading to intense environmental pollution of this region, accompanied by the significant impact of accumulated environmental damage in the region. The solution to these problems is difficult due to the remoteness of these areas and severe climatic conditions. Therefore, it is important to evaluate the potential for restoration of arctic soils. For this purpose, various indicators are used, including biological ones. In the analyzed arctic soil samples, high concentrations of petroleum hydrocarbons (up to 47,000 mg/kg) and chloride-ions (0.10–0.14 wt %) were established. Microbioassay demonstrated a presence of hydrocarbon-oxidizing microorganisms: Penicillium, Azotobacter chroococcum, Bacillus subtilis, Pseudomonas oleovorans. A low enzymatic activity and specific Arctic climate point out a low self-restoration ability of the soil, demonstrated the need for its remediation. The microbioassay with microbial strains identification and soil remediation methods suitable for the Arctic zone were recommended

The State of Migratory Landbirds in the East Asian Flyway: Distributions, Threats, and Conservation Needs

With nearly 400 migratory landbird species, the East Asian Flyway is the most diverse of the world’s flyways. This diversity is a consequence of the varied ecological niches provided by biomes ranging from broadleaf forests to arctic tundra and accentuated by complex biogeographic processes. The distribution and migration ecology of East Asian landbirds is still inadequately known, but a recent explosion in the number of studies tracking the migration of raptors, cuckoos, kingfishers and passerines has greatly increased our knowledge about the stopover and wintering ecology of many species, and the migratory routes that link northeast Eurasia and the Asian tropics. Yet the East Asian Flyway also supports the highest number of threatened species among flyways. Strong declines have been detected in buntings (Emberizidae) and other long-distance migrants. While the conservation of migratory landbirds in this region has largely focused on unsustainable hunting, there are other threats, such as habitat loss and increased agro-chemical use driven directly by land cover change and climate-related processes. Important knowledge gaps to be addressed include (1) threats affecting species in different parts of their annual cycle, (2) range-wide population trends, (3) ecological requirements and habitat use during the non-breeding season, and (4) the conservation status of critical wintering sites (including understudied farming landscapes, such as rice fields) and migration bottlenecks along the flyway
