Повышение эффективности отечественного рыболовства, как совокупности промышленных биотехнологий, создающих индустриальные системы высшего уровня, является одной из основных задач при реализации стратегии развития рыбохозяйственного комплекса страны в долгосрочной перспективе. В этой связи, базисным объектом системного исследования является промысловая зона рыбохозяйственного бассейна как многовидовая промысловая система взаимосвязанных и взаимообусловленных компонентов: ресурсного потенциала и рыбодобывающих единиц, образующих внутреннюю среду системы, совокупности условий ведения промысла, составляющих ее внешнюю среду. Исследование производственных процессов при статическом состоянии названной системы является основополагающим процессом, опирающемся на учете ее двуединой природы – биотехнологического дуализма. Обязательный его учет лежит в основе формирования оптимальных схем расстановки промысловых усилий в промысловых зонах при организации рыболовства, планировании и управлении производственно-технологическим процессом добычи водных биоресурсов на основе рациональной их эксплуатации и с целью повышения эффективности работы добывающего флота за счет повышения их эксплуатационного времени при годовом и рейсовом планировании. Решение оптимизационной задачи в статике в процессе моделирования таких производственно-технологических систем в статическом их состоянии направлено на проведение оптимизации рыбодобывающей деятельности с учетом биотехнологического дуализма, присущего многовидовым промысловым системам – промысловым зонам. Целью оптимизации является получение оптимального количества промысловых единиц, основанное на альтернативном принципе использования судов определенного типа. Improving the efficiency of domestic fisheries, as a set of industrial biotechnologies that create industrial systems of the highest level, is one of the main tasks in implementation of strategy for development of the country's fishery complex in the long term. In this regard, the basic object for a systemic study is the catching area of the fishery basin as a multi-species fishery system of interrelated and interdependent components: resource potential and fishery units that form internal environment of the system along with a set of conditions for catching activities that make up its external environment. The study of industrial processes in a static state of the named system is a fundamental process based on consideration of its dual nature: bio-inspired dualism. Its mandatory consideration underlies formation of optimal schemes for arrangement of fishery efforts in catching zones when organizing fishery industry, planning and managing the industrial process of harvesting aquatic biological resources based on rational operation thereof, and in order to increase efficiency of catching fleet by increasing its operating time during the annual and voyage planning. The solution for optimization problem in statics in the process of modeling such industrial-process systems in their static state is aimed at optimizing fishery activities taking into account the bio-inspired dualism inherent in multi-species fisheries: catching areas. The aim of optimization is to obtain an optimal number of fishery units based on an alternative principle of using vessels of a certain type.

Different Content

The paper presents data on the study of the content of carotenoids in plant fruits of different Sorbus species and varieties when introduced in the Komi Republic. As a result of a biochemical analysis, the accumulation of various amounts of carotenoids has been revealed: from 2,6 to 43 mg/%, depending on the species, sample and variety. The author compared the content of this group of substances in raw materials of plants introduced in the Komi Republic with the ones growing in other regions of Russia (Republic of Bashkortostan, Republic of Mordovia, Saratov, Penza, Moscow Region and others). It has been shown that under northern conditions in rowan fruits the value of the total carotenoids prevails in representatives of the Sorbus section with an East Asian range ( S. pohuashanensis , S. discolor , S. amurensis ), except the Far Eastern species S. sambucifolia . A different content of carotenoids in the plant fruits of S. aucuparia samples has been established: the maximum is in the sample from Yoshkar-Ola, which is 3-5 times higher than that in S. aucuparia from the Komi Republic. The content of this group of substances in the rowan fruits of the three studied varieties (Businka, Rubinovaya and Sorbinka) has been determined; their predominance in the Sorbinka variety has been shown. The study of the biochemical composition of plant raw materials of mountain ash species and varieties with the highest content of carotenoids when introduced in the North should be continued in order to further assess its qualitative composition and to develop recommendations for its use as a medicinal product, as well as a source of functional ingredients for pharmaceutical and food industries.

В работе предлагается организация планирования рейсооборота добывающих судов в многовидовой промысловой системе «промысловая зона» с учетом динамически меняющихся во времени условий ведения рыбодобывающей деятельности. Построены модель и алгоритм оптимизационной задачи планирования рейсооборота добывающих судов, учитывающие временные издержки и потери на всех этапах планирования промыслового рейса, на примере добычи кальмара командорского в Северо-Курильской зоне Дальневосточного рыбохозяйственного бассейна. Проведен факторный анализ промысловой деятельности группы добывающих судов, осуществлявших добычу кальмара командорского в период 2018-2019 гг. в Северо-Курильской зоне. Выявлены производственные и непроизводственные потери времени добывающих судов за период промысловой доступности исследуемого объекта, так же дана интервальная оценка временных издержек на каждом из трех этапов планирования рейсооборота для промысла кальмара командорского. The paper proposes the organization of planning the voyage turnover of mining vessels in the multi-species fishing system "fishing zone", taking into account the dynamically changing conditions of fishing activities. A model and an algorithm for optimizing the task of planning the voyage turnover of mining vessels, taking into account the time costs and losses at all stages of planning a fishing voyage, are constructed on the example of the production of Komandorsky squid in the North Kuril zone of the Far Eastern fisheries basin. A factor analysis of the fishing activity of a group of mining vessels that carried out the extraction of Komandorsky squid (Berryteuthis magister) in the period 2018-2019 in the North Kuril zone was carried out. Production and non-production time losses of mining vessels during the period of commercial availability of the object under study are identified, as well as an interval estimate of time costs at each of the three stages of planning the voyage rotation for the Komandorsky squid fishery.

Sefton, on the north side of Liverpool, holds a radioactive legacy from its industrial past. This legacy is in the form of Tin slag buried in sub-surface seams. Located near the docks and adjacent to the rich Lancashire coal seams, Sefton became one of the main production centres of Tin plate in Britain. A consequence of this industrial process is the production of mildly radioactive waste slag. Tin rich ores are heated under reducing conditions to produce a molten metal stream This is then separated into the component metal streams. Solid wastes produced by this process are known as slag and were usually stored on site in spoil heaps. Because this slag is a very hard, glassy material it has been historically used as aggregate in underlying roads and rail way sleepers. Many of these sites pre-date the introduction of the regulation of radioactive substances in the UK and have never been under legislative control under the Radioactive Substances Act, RSA93. There is a risk that the existence may not be known of some of these sites. U-238 and Th-232 and their associated decay chains, are the major contributors to the radionuclide inventory of the slags, levels of these radionuclides being in the range 1–10Bq/g. A series of alpha and beta decays for both chains leads eventually to the generation of a stable isotope of lead. Radiologically, the main area of concern is with the potential inhalation or ingestion of contaminated dusts. There is also a potential for Ra-226 to leach out into groundwater. AMEC has worked for Sefton Metropolitan Council and various developers, to carry out specialist, non intrusive gamma radiation surveys of numerous sites in Sefton. This is the first stage in carrying out a radiological risk review of a given site. What often then follows is an intrusive, geo-technical survey, with trial pitting and radiological sampling for later sensitive lab based radiochemical analysis. Radiological supervision is also required at this time to ensure that the radiological exposure of the Contractors carrying the survey is restricted and ensure that plant dose not become contaminated with radionuclides. These surveys are the preliminary stage for redevelopment works with new housing replacing antiquated commercial premises. By bringing together expertise in sensitive gamma surveying, radiochemical analysis and a detailed understanding of the regulatory framework, AMEC is able to support the borough of Sefton in its re-development programme ensuring safe compliant development of an area with an historic radiological legacy.

Minimize Costs

Overall, in Sri Lankan public schools, the student–teacher ratio is very low. The number of teachers is considerably greater than the number of classes; sometimes the former is double or more than double the latter. In a school in which all the teachers are individually deployed in each class, many teachers have to remain idle. Thus, every day a certain number of teachers remain idle. This situation points to two issues. Firstly, in Sri Lankan public schools, resources are underutilized and hence costs are not minimized. Secondly, since there is an excess of teachers in schools, a formal and logical method is required to determine the optimal number of teachers. This article tries to develop a formula to determine the required number of teachers for a school, and thereby to find ways to minimize costs when employing teachers. Primary data on classes, teachers and subjects offered with respect to 40 public schools in the North Central Province were collected. When empirical data on the number of teachers in sampled schools were compared with calculated teacher requirements in terms of the developed formula, it was found that school authorities are underutilizing teachers. The article concludes that (a) based on the developed formula to determine the required number of teachers, many public schools have an excess of teachers and hence current transfer policy for school teachers is not logical, (b) teacher requirement can be decided according to the developed formula and (c) by adopting one teacher-two subjects-one school and one teacher-one subject-more schools models, government authorities can minimize costs further.

ABSTRACT The aim of this study was to estimate the optimum plot size and number of replications in papaya field experiments. Eleven variables were evaluated in four cultivars of papaya with planting in different seasons between 2011 and 2013 in the north of the Espírito Santo state. Analysis were made from blank test applied to 240 selected for planting season and cultivate plants in commercial fields. The determination of optimum plot size was performed by applying the methodologies of modified maximum curvature and maximum curvature of coefficient of variation. The determination of the number of repetitions was taken from the least significant difference in average 20% and 30%. The optimum plot size proved the same by the two methods studied for most evaluations. The optimum size required differs among cultivars, between variables and between planting seasons, with the largest number of plants was required for the variables number of fruits per plant and yield per plant. We conclude that the optimal number of papaya plants planted in the field is six plants per plot using three replications.

Scientific-research center «Arktika» far-eastern branch of the Russian academy of sciences, 685000, Magadan, Russia Young male residents ofMagadan region and Chukotsky Autonomous District aged 17-21, all are representatives of Russia’s northeast ethnic peoples were examined in comparison with Caucasoid subjects born in the north in the p>-2 generation to study the blood lipid and glucose values as well as the dietary structure. In order to ascertain the subjects ’ lipid and carbohydrate basic values, the CardioChek PA biochemical express-analyzer (USA) was used during the study of the capillary blood samples taken from the examinees on empty stomach, 10-12 hours after the last meal. Besides, the program set of “ASPON-nutrition” was used to analyze the subjects ’ daily diets for assessing their dietary structures and nutrition facts. All the examined subjects demonstrated the similar changes in lipid-carbohydrate profile resulted in low fat metabolism and high glucose close to the upper limit of physiological norm. Reliable ethnic and region-related peculiarities in the studied metabolic parameters were found. Of note, that Aboriginal subjects were the highest in the blood glucose. They showed higher values ofLPHD and lower values ofLPLD compared to those of Caucasoid subjects. Significant nutrition irrationalities such as imbalance in macronutrients and energetic deficiency were found. The observed diets contain excess carbohydrates and insufficient protein and fat saturation at lowered daily energetic value for the given age cohort.

Foreign researchers are testing Gibrat’s law on the example of firms, regions and countries. The importance of empirical confirmation of this law lies in the fact that it allows us to determine whether the population of a city, region or country as a whole has a common growth path and whether there is single size dependence between them. The relevance of this study is determined by the need to expand the indicators to assess the growth of cities using Gibrat’s law in modern Russian conditions. The purpose of the article is to analyze the feasibility of Gibrat’s law in Russian cities by indicators: population of the city, population density in the city, average annual number of employees in enterprises in the city, average monthly wage in the city, number of enterprises and organizations in the city, as well as to determine the appropriateness of using this law for urban systems of Russia. In the Ural, Siberian and Far Eastern federal districts (2009–2016), in the North-Western, Volga, Siberian and Far Eastern federal districts (2016–2018), the growth rate of cities does not depend on their initial size. Gibrat’s law was confirmed for the following indicators: population density in a city in 2009–2016 in the Siberian Federal District, in 2016–2018 in all federal districts, except for the North Caucasian Federal District; average annual number of employees in a city in the Southern (2003–2009, 2009–2016), Ural (2009–2016), Siberian (2009–2016), Northwestern (2016–2018), North Caucasian (2016–2018) and Far Eastern (2016–2018) federal districts; average monthly salary in the cities of the Siberian Federal District (2009–2016), in the Central, Northwestern and Ural Federal Districts (2016–2018); number of enterprises and organizations in the city in the Southern Federal District (2009–2016), in the North Caucasian, Volga, Ural and Siberian federal districts (2016–2018).

Based on the analysis of All-Union Population Census of 1926 and a wide range of general and regional scientific research, the author studies the processes of demographic and economic development of territories located in the Russian North and conventionally designated by the author as regions of Euro-pean, Ural, Siberian and Far Eastern North. The paper identifies key trends and features of Northern re-gions' development in the 1920s, caused by the first Soviet reforms of the administrative-territorial struc-ture of the country, economic development and national state policy, which had an impact on the demo-graphic processes in the regions including population size, its composition and settlement structure. It is found that the economic development was the most active in the bordering areas, where intensive development of industry and transportation implied the need to strengthen national defense and expand trade and economic ties. This mainly concerned the regions of the European and Far Eastern North. The regions that were rich in natural resources, especially gold deposits, such as Yakutia, also developed more actively. Other regions of Ural and Siberian North developed in a more traditional way, based on growth of wood harvesting and fishing industry. Improving of living conditions of the indigenous peoples of the North, material support for their farms, medical care and legal assistance, introduction of education among the population in the 1920s had a positive impact on the economic and demographic development of the indigenous population.

The Walrus is confined to the northern circumpolar regions, its range northward apparently extending to the limit of perpetual ice. Now rare in Iceland, Odobenus rosmarus is stated to be still not unfamiliar in Hudson Bay, Davis Strait, and Baffin Bay north to Ellesmere Land, the coasts of Greenland, Spitsbergen, Novaia Zemlia, and the western part of the north coast of Siberia; in all of which regions, however, persecution has greatly diminished its numbers. The species does not extend along the far eastern part of the north Siberian coast, and Walrus are not met with again until the north-eastern extremity of Siberia is reached. Here the Pacific Walrus, which differs somewhat from that of the Atlantic side and is regarded as a distinct species, Odobenus obesus, is reported from Cape Chelagskai, in longitude 170° E., along the Siberian coast as far as northern Kamschatka south to latitude 60°, also on some of the islands in the Bering Sea, and on the opposite coast of Alaska south to about latitude 55° and eastward to Point Barrow. Here again a long gap along the Arctic coast of North America, from Point Barrow in longitude 158° W. to the western shore of Hudson Bay in longitude 97° W., separates the Pacific from the Atlantic Walrus.

ON zoogeographic maps, the Solomon Islands are shown as the north-eastern limit of Australidelphian marsupial distribution in Australasia. This distinction is due to the presence of a single New Guinean marsupial, the northern common cuscus Phalanger orientalis, which was probably introduced via the Bismarck Archipelago by prehistoric human agency (Flannery 1995; Spriggs 1997; Heinsohn 1998; Wickler 2001). P. orientalis is found across most of the principal Solomon Islands, with the exception of the remote far-eastern oceanic islands of Santa Cruz (Temotu) Province. In the scientific literature, the exact eastern limit of distribution for P. orientalis is generally given as San Cristobal (Makira) Island in Makira Province (Laurie and Hill 1954; Flannery 1995), the eastern most peninsula of which extends to 162� 23' E. The next landmass to the east is the small 5 km diameter and 143 m high limestone atoll of Santa Ana (Owa Rafa) which lies across a 7.5 km open water crossing.
