The possibility to use multi-wavelength regime of total stations operation for making surveys under heavy aerosol atmosphere pollution is researched. The actuality of single- and multi-wavelength regimes rational choice under heavy aerosol atmosphere pollution is grounded. The task on researching the matter of operational regime choice for total stations is formulated. The method for solution of the formulated task is suggested. The theoretical modelling and experimental researches are held to formulate the criterion for choice of single- or multi-wavelength regimes. The practical recommendations for such a choice are formulated. The practical recommendations are formulated for choice of measurements regime. According to formulated recommendations if a single-wavelength total station operates in the field of longer wavelengths (R) of visible band and a three-wavelengths one operates with bias to shorter (B, G, R) wavelengths, the single-wavelength total station should be preferred. But if the single-wavelength total station operates in the field of shorter wavelengths (B) and the three-wavelengths one operates with bias to longer wavelengths (B, G, R) then the multi-wavelengths total station should be preferred. The recommendation described in this article are relevant for both the regimes of measurements with- and without reflector and can be useful for users of total stations.

В статье исследуется соотношение трёх главных человеческих ценностей – истины, добра и кра­соты. Критический анализ известных философских положений проводится с использованием результатов, полученных в современных экспериментальных исследованиях. В частности, обсуждается противоречие между требованием о приоритете истины перед добром в ситуации конфликта между этими ценностями и воздействием позитивных иллюзий, выявленных современной нейронаукой и свойственных функцио­ни­ро­ванию человеческого мозга. Так, широко распространен эффект «ложной уникальности», при котором че­ловек переоценивает собственные (точнее, высоко желаемые) позитивные качества и недооценивает нега­тивные. Массовая приверженность индивидов заблуждениям относительно величины своего внутреннего по­тенциала, наличия глубоко скрытых ресурсов в сочетании со стремлением поддержать высокую само­оцен­ку ведут к искажению проводимых социальных сравнений. Автор доказывает, что придание добру боль­шей значимости в сравнении с истиной неминуемо ведёт к последующей победе зла над добром. По­добное происходит в связи с большей доступностью и привлекательностью «неистинного» добра перед «ис­тинным». Главное преимущество опоры на истину заключается в её умении распознавать и отделять дол­го­вре­менные разновидности добра от его краткосрочных (как правило, гедонистически ориен­ти­ро­ванных) вариантов, нередко оборачивающихся злом в более отдалённой перспективе. Настоящее (истин­ное) добро, как правило, требует приложения первоначальных усилий, однако приносит пользу в течение длительного времени и оборачивается другими полезными эффектами. В конце статьи приводятся практические рекомендации, а также личный опыт автора, позволяющие информированному индивиду организовать собственное мышление и поведение с учётом выявленных закономерностей.     The article investigates the ratio between the main three human values – the truth, the good and the beauty. The analysis of the well-known philosophical postulates is conducted with the help of the results obtained in modern experimental researches. In particular, the author discusses the contradiction between the demand of the truth priority if the latter gets in conflict with the good, and the influence of the positive illusions, discovered by modern neuroscience and peculiar to human brain functioning. Thus the wide-spread effect of false uniqueness makes a person to overestimate her own (in fact highly wished) positive traits of character and underestimate negative ones. Mass proneness to the beliefs about individual inner potential and deeply seated resources combined with the desire of high self-esteem lead to the wrong social comparisons. The author of the paper proves that the priority of the good in comparison with the truth inevitably causes the situation, in which the evil defeats the good. This occurs because the untrue good is more easily achieved and utilized than the true good. On the contrary, the main advantage of the priority of the truth is the ability to discern and make distinctions between long-term forms of the good and its short-term (as a rule, hedonistically oriented) variants, which often turn to evil in the future perspective. As a rule, the genuine (true) good demands some efforts from an individual at first, but brings benefits and numerous useful effects for much longer periods of time. At the end of the paper, the author gives practical recommendations and shares his personal experience, which can help the informed individual to organize his own thinking and behavior with the help of the discovered regularities.

AbstractThe formation of cold filaments in the low corona is a central research area in solar physics. Their basic properties are not well understood, but they may be crucial for the mass and magnetic flux balance in the solar corona. The review discusses multi-wavelength observational results and theoretical modelling of filament channels and quiescent filaments.

Have been presented results related to complex experimental researches of refinery furnaces’ operating gas burners with a various design of devices for swirl and supplying of the air stream, connected with ecological efficiency of these burners’ work. Have been shown graphic dependences for influence of air swirl degree in blowing burning devices on produced nitrogen oxides’ concentration and created sound pressure’s level at the work of these devices. Have been established the reasons for raised emission of nitrogen oxides and noise level at operation of investigated gas burners. Have been demonstrated ecological advantages for blowing burning devices of GP‑2 type as least toxic and noisy burners from among the investigated ones. Have been given practical recommendations on the increase of ecological efficiency related to operation of refinery furnaces’ blowing gas burners.

The development of the physics of the solar atmosphere during the last 50 years has been greatly influenced by the increasing capability of observations made from space. Access to images and spectra of the hotter plasma in the UV, XUV and X-ray regions provided a major advance over the few coronal forbidden lines seen in the visible and enabled the cooler chromospheric and photospheric plasma to be seen in its proper perspective, as part of a total system. In this way space observations have stimulated new and important advances, not only in space but also in ground-based observations and theoretical modelling, so that today we find a well-balanced harmony between the three techniques.
