Заглавие: Goals of humanity and mind

Количество страниц: 14 с.

We are not interested in the myths and misty legends presented as truthful. For example, we consider the question of the existence of souls and spirits as a scientific problem and are not in a hurry to adopt a point of view before research in this field is progressing. As proofs of the existence and survival of a soul or the souls of a man are not convincing, instead of thinking a lot about the possibility of entering a hypothetical paradise after death and escaping the hell, we are interested in research aimed at the prolongation of human life and even in the different possibilities of attaining immortality, the problems of salvation of mankind and the more general problem of development of the Mind in the Universe.
Нас не интересуют мифы и легенды, представленные как правдивые. Например, мы рассматриваем вопрос о существовании душ и духов как научную проблему и не торопимся принимать какую-то точку зрения, пока исследования в этой области не прогрессируют. Поскольку доказательства существования и выживания души или душ человека неубедительны, вместо того, чтобы много думать о возможности попасть в гипотетический рай после смерти и избежать ада, мы заинтересованы в исследованиях, направленных на продление жизни и даже в различных возможностях достижения бессмертия, проблемах спасения человечества и более общей проблеме развития Разума во Вселенной.

Заглавие: Hemostatic system in chronic viral hepatitis

Количество страниц: 6 с.

Hepatocellular carcinoma is one of the most common malignant tumors with a high rate mortality of patients without adequate therapy. Thus, early diagnosis of hepatocellular carcinoma is crucial for improving the quality of life and the survival rate for patients. Measuring the concentration of O-fetoprotein and liver ultrasound are commonly used in the early diagnosis of liver cancer. However, the sensitivity and specificity of measuring O-fetoprotein in liver cancer screening is not always satisfactory. Achievements of biochemistry, molecular genetics and systems biology in the integrative analysis of tumors and their environment led to the identification of new molecular markers of hepatocellular carcinoma, which may be promising tools to improve the existing algorithms of diagnosis and treatment of hepatocellular carcinoma.
Гепатоцеллюлярная карцинома является одной из наиболее распространенных злокачественных опухолей, характеризующаяся неблагоприятным жизненным прогнозом при отсутствии своевременного и адекватного лечения. Таким образом, ранняя диагностика гепатоцеллюлярной карциномы имеет решающее значение для улучшения качества и увеличения продолжительности жизни. Измерение концентрации Ot-фетопротеина и ультразвуковое исследование печени используются для ранней диагностики рака печени. Однако, чувствительность и специфичность измерения О-фетопротеина в скрининге рака печени не всегда являются удовлетворительными. Достижения биохимии, молекулярной генетики и системной биологии в интегративном анализе опухолей и их окружения привели к идентификации новых молекулярных маркеров гепатоцеллюлярной карциномы, которые могут быть перспективными инструментами для улучшения имеющихся алгоритмов диагностики и лечения гепатоцеллюлярной карциномы.

Заглавие: High-latitude peculiarities of the geomagnetic SI impulse propagation meridional velocity during sharp decrease of solar wind density

Количество страниц: 4 с.

The geomagnetic manifestation of sudden impulse (SI) caused by a sharp decrease of the solar wind dynamic pressure due to the plasma density reduction is considered. The observational data of the magnetometer world network have been analysed. The propagation velocities of the SI signal in the meridional direction by using data of the horizontal component of geomagnetic field in the high-latitude region have been calculated. It is found that at a sharp decrease of the solar wind density the meridional propagation of the SI signal is in the northern direction. In this case, on the day side the propagation velocity is constant but there is a tendency of its increasing in the MLT morning sector. It has been established that the meridional propagation velocity of the SI signal at a sharp decrease of the solar wind density depends on the geomagnetic latitude, i.e. with the rise of latitude the velocity in the auroral zone decreases and in the polar cap it increases.

Заглавие: Hydrocarbon solvents on the hexane base for oil organic deposits elimination of the irelyakh gas and oil field

Количество страниц: 8 с.

The group composition of asphaltene-resin-paraffin deposits (ARPD) in the Irelyakh field and their solubility in the composite solvents on the hexane base with the additives consisting of nonionic surface-active substances (NSAS) and concentrates of aromatic hydrocarbons is determined. The results of the investigations show that the additives Neonol AF-9-10 and liquid products of pyrolysis (LPP) are most efficient. The use of these additives allows to increase the efficiency of ARPD breaking and dissolving by 1,3 – 1,6 times as compared with a base solvent. It is shown that the increase in the concentration of individual additives from 0,5 to 3 % causes a decrease in the efficiency of detergent compounds.

Заглавие: Influence of a change in solar magnetic field polarity on the Jovian electron flux intensity

Количество страниц: 3 с.

The Jupiter is a powerful regular source of high-energy electrons (0,2-40 MeV). In this connection their density in the near-Earth space systematically increases with a period of 399 days, which is coincident with the synodic period of Jupiter. According to our estimations, their energy is sufficient to produce a significant local reduction of the magnetic field in the IMF sector connected with the Jupiter. In this paper the evidence is presented that the electron fluxes in the Jovian sector are controlled by the general magnetic field of the Sun. A treatment of 399-day intervals of the electron fluxes and IMF, obtained from spacecraft data for the period of 1963 to 2000 has been performed by superposed epoch technique taking into account the periodic change of the solar magnetic field polarity. Having adopted the Jupiter opposition day to be an epoch zero, the changes in particle intensity and IMF components under different signs of the general magnetic field of the Sun are found by using a large dataset (9925 days). The times of 399-day variation maxima in different periods of solar activity are compared and a character of their displacement relative to Jupiter opposition momentsis discussed.

Заглавие: Influence of IMF by on the location of western electrojets during the magnetic storm on Nov. 9-10, 2004

Количество страниц: 4 с.

The spatial-temporal distribution of westward electrojets in the northern hemisphere has been investigated using geomagnetic ground observation data for November 9-10, 2004 geomagnetic storm. It is shown that the location of the maximum westward electrojet depends on the IMF orientation. It is in the evening or morning sector when Bγ0. With the increase of positive IMF Bγ, the region of intensity maximum shifts to morning hours. Thus, the azimuthal IMF component not only controls the pattern of magnetospheric convection, but also affects the longitudinal location of the westward electrojet pattern during the magnetic storm.

Заглавие: Influence of Jupiter on cosmic ray intensity variations

Количество страниц: 4 с.

Galactic cosmic ray (GCR) diffusion in interplanetary space depends in a certain way on the degree of regularity of the interplanetary magnetic field (IMF). The sector IMF structure is manifested in inhomogeneous GCR distribution in the heliosphere. In parallel with the usual sectors associated with solar activity, one should take into account the sectors, which are caused by the Jupiter activity. It is known that the Jupiter is a powerful regular source of high-energy electrons (0.2-40 MeV), the density of which, on the average, is many times higher than that of solar cosmic rays. The high-energy electrons are systematically registed with the 399-day period in the near-Earth space. According to estimations of the particle energy density their flux is sufficient to decrease the magnetic field in the Jovian sector and can due to corresponding large-scale inhomogeneity in the GKL distribution. Hereby, we present the evidences that the GCR diffusion is noticeably stronger in the sector where there are Jovian electrons. By data on periodic passage of those sectors near the Earth, we have treated neutron monitor data using the superposed epoch technique. The day of the Earth and Jupiter opposition is taken as a zero epoch. At large statistical data (9925 days) it is found that the GCR intensity in that period increases with an amplitude near 1%. The groud effect is manifested with the period of 399 days and its maximum time is in a certain way shifted relative to the planet opposite moment.

Заглавие: Investigating tensor anisotropy of cosmic rays during large-scale solar wind disturbances
Исследование тензорной анизотропии космических лучей во время крупномасштабных возмущений солнечного ветра

Количество страниц: 5 с.

Впервые произведено разложение наблюдаемой анизотропии космических лучей на зональные гармоники и компоненты векторной и тензорной анизотропии. Рассмотрены события форбуш-понижений космических лучей, произошедших в ноябре 2001 г и ноябре 2004 г. Показано, что в начале форбуш-понижения преобладает конвекционный ток космических лучей, направленный от Солнца, а в период восстановления интенсивности - диффузионный ток частиц вдоль межпланетного магнитного поля в сторону Солнца. На фазах спада интенсивности космических лучей наблюдается кратковременное уменьшение величины второй зональной гармоники, которое совпадает с резкими скачками напряженности межпланетного магнитного поля и скорости солнечного ветра. Во время прохождения крупномасштабных возмущений солнечного ветра тензорная анизотропия ведет себя сложным образом, для объяснения ее поведения требуется дальнейшее детальное исследование.
The observable anisotropy of cosmic rays has first been decomposed into zonal harmonics and components of vector and tensor anisotropy. We examine Forbush decreases in cosmic rays that occurred in November 2001 and November 2004. It is shown that at the beginning of a Forbush decrease an antisunward convective current of cosmic rays predominates; and during the recovery phase, a sunward diffusive current of particles along the interplanetary magnetic field dominates. During the phase of intensity drop, short-time decreases in the second zonal harmonic take place. These decreases occur with abrupt changes of the interplanetary magnetic field intensity and solar wind speed. During the passage of large-scale solar wind disturbances, the tensor anisotropy behaves in a complicated way. To explain its behavior, a further detailed investigation is required.
