    DEVELOPMENT OF THE CRITERION AND THE METHOD OF ESTIMATION OF THE COMPLEXITY OF THE STRUCTURE OF TECHNOLOGICAL SYSTEMS

    No full text
    In the process of designing, manufacturing and operating complex technological systems, it is necessary to have criteria and methods for assessing the perfection of their structure. A method for assessing the complexity of the structure of technological systems by the criterion that is a complex quantity and takes into account the number of system elements, connections between elements, connections between elements and the external environment, and the hierarchical level of elements in the system is developed. The choice of the criterion was made under the following assumptions: the element of the system has one «input» and one «output», through which its interaction with other elements of the system and the external environment occurs; the state of the system element is uniquely determined by the state of its «input». The complexity of the structure of the unit element is unity; the complexity of the structure of the system consisting of an infinite number of elements is equal to infinity. The complexity of the system structure is determined by the number of system elements, the number of connections between them and the external environment, and also the hierarchical level of the element in the system. The method for assessing the complexity of the structure of technological systems is sufficiently accurate, intuitively acceptable and suitable for practical research. Application of the developed method in practice allows solving the problem of objective analysis of the structure of complex technological systems and giving them a quantitative assessment. An example of using the method for analyzing the structure of technological equipment systems of sintering plants of the Krivoy Rog iron ore basin (Ukraine) is give

    In this paper the author presents data concerning quantitative occurrence of the Oribatei - intermediate hosts of Moniezia (M.) expansa (Rud.) in some plant associations: Mol - Molinietum coeruleae (wet meadows), Arrh – Arrhenatheretum elatioris (fresh meadows), Aln - Alnetum glutinosae typicum (alder wood), QC - Querceto-Carpinetum (oak-horn-beam-wood), DP - Dicrano-Pinetum (pine-wood) in the vicinity of Poznań (table 1). The numbers mean specimens per sq. m. The quantity found means the number of specimens received in the Tullgren apparatus. The real quantity is calculated by applying the correction after Forsslund, 1948 and Müller-Naglitsch, 1957. Further on the author discusses the results: The Oribatei - intermediate hosts of Anoplocephalata are more abundant in the meadows (39-51 thousands per sq. m.) than in the woods (17-26 thousands per sq. m.). In the different habitats (meadows, woods) the quantity of the intermediate hosts increases with the humidity of the soil. In the meadows the number of the intermediate hosts is proportional to the whole quantity of the Oribatei. In the woods this relation is rather reversed

    From 1966 to 1967 the author carried out an investigation on the helminth fauna of gar-fish Belone belone (L.) from Puck Bay of the Baltic. It was established, the next species parasitise in gar-fish: Diplostomum spathaceum (Rud.), Tylodelphys sp., Scolex pleuronectis Mull., Contracaecum aduncum (Rud.), Cucullanus truttae (Fabricius), Pomphorhynchus laevis (Zoega), and Neoechinorhynchus rutili (Mull.). With exception of Pomphorhynchus laevis (Zoega) they were not found in gar-fish yet, but they occur commonly in the other Polish fishes

    20 years of co-operation between Sweden and Russia: ECO-TECH and ECOBALTICA conferences

    Co-operation between University from Kalmar city and Saint-Petersburg State Polytechnic university and now with Federal State Budgetary Scientific Institution “All-Russian Research Institute of Phytopathology”, Russia which start in 1996 help for development understanding between Sweden and Russian. This topic we show benefit of this co-operation for Baltic region. Twenty years of cooperation between Russia and Sweden is of course not only ECO- TECH and ECOBALTICA. However, including the conferences ECO- TECH and ECOBALTICA. This cooperation was initiated and for several years was carried out without any agreements and based on human trust of key stakeholders. Only 1999 in Kalmar was signed a Memorandum of Understanding between University of Kalmar (now - Linnaeus university) and Saint-Petersburg State Polytechnic University. 1. To initiate and develop co-operation for Cooperation ECO-TECH and ECOBALTICA conferences created a new philosophy of scientific youth conferences, which then was recommended a long time used in Russian universities, on the recommendation of the coordinating councils of Youth Affairs of Russia. We kindly thanks to the Academician of Russian Academy of Sciences Michail Sokolov ( Moscow) and also to the Academician of Russian Academy of Sciences Yuriy Vassiliev (Saint-Petersburg), professor William Hogland and professor Marcia Marques Gomes ( both - Linneaus University) for support.Co-operation between University from Kalmar city and Saint-Petersburg State Polytechnic university and now with Federal State Budgetary Scientific Institution “All-Russian Research Institute of Phytopathology”, Russia which start in 1996 help for development understanding between Sweden and Russian.

    Karma and the United States Government: How Mass Incarceration Policies Created an Ailing and Costly Aging Population in the Prison System and How Can Civil Legal Services Assist the Elderly After Release

    No full text
    The note argues that mass incarceration policies in the U.S. have led to a growing population of elderly inmates, resulting in significant financial and health burdens. The author emphasizes the critical role of civil legal services in assisting these individuals post-release, particularly in addressing challenges related to employment, housing, and healthcare. The central argument is that tailored legal aid can mitigate the unique struggles faced by elderly ex-offenders, thereby reducing recidivism and improving community integration

    Governance and Tradition in Nineteenth-Century Greenland

    No full text
    : This article investigates the way in which the concept of tradition was evoked in the colonial policies in nineteenth-century Greenland. The author argues that ‘tradition’ provided colonial officials in Greenland with a strategy that enabled them to make fundamental changes appear as a restoration of a Greenlandic culture en route to its own destruction. The colonial authorities claimed that the establishments of new institutions were facilitating a return to the traditional practices of the past. Further the author argues that reforms effectuated in the latter part of the nineteenth century reflect a fundamental shift in the rationality behind the colonial project in Greenland. This analytical point is reached through the deployment of the theoretical concept colonial governmentality. Following the work of scholars such as Nicholas Thomas, David Scott and Gyan Prakash, it is argued that a significant shift toward social engineering techniques (of governance) happened in the period. The new techniques were employed in order to structure of the life world of the Greenlanders, and ultimately shape their individuality. Finally the article draws attention to the short and long term consequences of the political utilization of tradition

    The author examined 2145 juvenile individuals of cape hake, Merluccius capensis Castelnau, 1861 caught off Namibia. The presence of larval Anisakis simplex (Rud., 1809), larval Hepatoxylon trichiuri Holten, 1802 as well as Parabrachiella australis Wilson,1923 was revealed. The degree of infestation was related to sex and age of the fish.
