    У статті розроблено уточнену класифікацію видів розвитку підприємств. Уточнено сутність та зміст категорії адаптивного розвитку підприємства, його місце в загальній класифікації. Використовуючи загальнонаукові методи дослідження (аналіз та синтез, індукція та дедукція, спостереження, логічне узагальнення), сформульовано сутність адаптивності як властивості розвитку підприємств. Запропоновано систему класифікації видів розвитку та визначено місце адаптивного розвитку в ній.В статье разработана уточненная классификация видов развития предприятий. Уточнены сущность и содержание категории адаптивного развития предприятия, его место в общей классификации. Используя общенаучные методы исследования (анализ и синтез, индукция и дедукция, наблюдение, логическое обобщение), сформулирована сущность адаптивности как свойства развития предприятий. Предложена система классификации видов развития и определено место адаптивного развития в ней.The article develops the classification of the types of enterprise development. The nature and content of the category of adaptive development of the enterprise and its place in the general classification are clarified. With the usage of the general scientific methods (such as analysis and synthesis, induction and deduction, observation, logic synthesis), the essence of adaptability, as a property of companies development, was formulated the. The system of types of development classification is proposed and the place of adaptive development in it is defined

    Some results of cislunar plasma research

    The main results of plasma cislunar investigations, carried out during Luna-19 and Luna-22 spacecraft flights by means of dual frequency dispersion interferrometry, are briefly outlined. It is shown that a thin layer of plasma, with a height of several tens of kilometers and a maximum concentration of the order 1,000 electrons/cu cm exists above the solar illuminated lunar surface. A physical model of the formation and existence of such a plasma in cislunar space is proposed, taking into account the influence of local magnetic areas on the moon

    Dual frequency radio sounding of the Martian nighttime ionosphere was carried out during the exits from behind the planet of the Mars-4 spacecraft on February 2, 1974 and the Mars-5 spacecraft on February 18, 1974. In these experiments, the spacecraft transmitter emitted two coherent monochromatic signals in decimeter and centimeter wavelength ranges. At the Earth receiving station, the reduced phase difference (or frequencies) of these signals was measured. The nighttime ionosphere of Mars measured in both cases had a peak electron density of approximately 5 X 1,000/cu cm at an altitude of 110 to 130 km. At the times of spacecraft exit, the solar zenith angles at the point of occultation were 127 deg and 106 deg, respectively. The height profiles of electron concentration were obtained assuming spherical symmetry of the Martian ionosphere

    Geological-morphological description of the Ishtar Terra (photomap of the Venusian surface sheet B-5)

    Get PDF
    The main part of the Ishtar Terra east of the Maxwell Montes is covered with systems of areal dislocations of several directions, which are called Parquet. According to the structural patterns these may be divided into: (1) the central stable block; (2) the lesser peripheral blocks separated from the central one by gaps and grabens; (3) the zones of mobilized parquet, whose substance flowed downward at an incline in the directions away from the central block in the form of plastic flows; and (4) the partially parqueted lava sheets. The Maxwell Montes were formed as a result of the collision between the central parquet block and the Lakshmi Planum

    B\"{a}cklund transformations for the constrained dispersionless hierarchies and dispersionless hierarchies with self-consistent sources

    Full text link
    The B\"{a}cklund transformations between the constrained dispersionless KP hierarchy (cdKPH) and the constrained dispersionless mKP hieararchy (cdmKPH) and between the dispersionless KP hieararchy with self-consistent sources (dKPHSCS) and the dispersionless mKP hieararchy with self-consistent sources (dmKPHSCS) are constructed. The auto-B\"{a}cklund transformations for the cdmKPH and for the dmKPHSCS are also formulated.Comment: 11 page

    Generalized Darboux transformations for the KP equation with self-consistent sources

    Full text link
    The KP equation with self-consistent sources (KPESCS) is treated in the framework of the constrained KP equation. This offers a natural way to obtain the Lax representation for the KPESCS. Based on the conjugate Lax pairs, we construct the generalized binary Darboux transformation with arbitrary functions in time tt for the KPESCS which, in contrast with the binary Darboux transformation of the KP equation, provides a non-auto-B\"{a}cklund transformation between two KPESCSs with different degrees. The formula for N-times repeated generalized binary Darboux transformation is proposed and enables us to find the N-soliton solution and lump solution as well as some other solutions of the KPESCS.Comment: 20 pages, no figure
