Secular variation of hemispheric phase differences in the solar cycle

We investigate the phase difference of the sunspot cycles in the two hemispheres and compare it with the latitudinal sunspot distribution. If the north-south phase difference exhibits a long-term tendency, it should not be regarded as a stochastic phenomenon. We use datasets of historical sunspot records and drawings made by Staudacher, Hamilton, Gimingham, Carrington, Spouml;rer, and Greenwich observers, as well as the sunspot activity during the Maunder minimum reconstructed by Ribes and Nesme-Ribes. We employ cross-recurrence plots to analyse north-south phase differences. We show that during the last 300 years, the persistence of phase-leading in one of the hemispheres exhibits a secular variation. Changes from one hemisphere to the other leading in phase were registered near 1928 and 1968 as well as two historical ones near 1783 and 1875. A long-term anticorrelation between the hemispheric phase differences in the sunspot cycles and the latitudinal distribution of sunspots was traced since 1750.Comment: 7 pages, 4 figure

First solar butterfly diagram from Schwabe's observations in 1825-1867

The original sunspot observations by Heinrich Samuel Schwabe of 1825-1867 were digitized and a first subset of spots was measured. In this initial project, we determined more than 14 000 sunspot positions and areas comprising about 11% of the total amount of spots available from that period. The resulting butterfly diagram has a typical appearance, but with evident north-south asymmetries.Comment: 3 pages, 1 figure, Proceedings of IAU symposium 273, Physics of Sun and star spots, Ventura, California 22-26 August 201

Technology prevention of addictive behavior in children as part of a healthy lifestyle

Purpose : to develop a technology of social and educational prevention of addictive behavior in children as part of the organization of a healthy lifestyle. Material : a theoretical analysis and compilation of more than 50 sources of scientific and methodological literature. Applied methods of modeling and design of social and educational activities. Results : the technology of social and educational prevention of addictive behavior of children in the territorial community. The main components of addictive behavior prevention technologies children are: diagnostic levels of addictive behavior of children in the territorial community; goal-prevention technologies, the choice of technology development or prevention of addictive behavior in children, preparation and planning of prevention, the introduction of technology, expertise and evaluation of the effectiveness of the technology deployed, summing outcomes. Conclusions . prevention of addictive behavior is an integral part of the organization of a healthy lifestyle for children. Procedural embodiment prevention of addictive behavior of children in the life of the territorial community is represented as a developed social and educational technology

3D movies at home

During the three-dimensional images - the future of home cinema. However, in order to make this "magic" idea was embodied in practice need to successfully achieve two main objectives: "to equip" the film industry standard equipment to capture and further processing of 3D-video content, available to develop end-user tools for viewing movies in surround format, 3D Full HD . And although the three-dimensional image has not won a home theater, a time when every "home-cinema-goer will receive the opportunity to watch three-dimensional movies at home, getting closer.

Elements Distribution in Soil and Plants of an Old Copper Slag Dump in the Middle Urals, Russia

The elements concentration in soil and accumulation in plants growing spontaneously on an old copper slag dump were studied. The research object was a landfill site of the Polevskoy copper smelter (Middle Ural, Russia), which is about 200 years old. We investigated composite samples, consisting of soil blocks (20 x 20 cm) with growing plants. Samples were selected on a transect of 4–5 m at equal intervals. The composite sample was divided into slag fractions: stone, gravel, fine soil (particles smaller than 1 mm); plant fractions: moss and roots, stems and leaves. The microelement analysis of the samples was carried out at an analytical center of the Institute of Geology and Geochemistry, Ural Branch of RAS. The analyses were performed by inductively coupled plasma mass-spectrometry using Elan-9000 ICP massspectrometer. The formation of technogenic soil with a thickness of 10–15 cm on the dump of cast copper slag has begun two hundred years ago. Fine soil constitutes more than one third of the technogenic soil mass and acts as a sorption geochemical barrier. Fine soil accumulates elements mobilized from slag. The concentration of most elements in fine soil is 1–2 orders of magnitude higher than their concentration in slag stone. Pb, Cd, Bi are particularly effectively retained in fine soil: their content is 700-1000 times higher than in slag stone. In the conditions of unlimited supply of elements released from slag, plant reaches the upper threshold of accumulation. The aboveground plant parts compared to litter (roots and moss) have a lower concentration of all elements, but they show the stronger ability to accumulate selenium

Warm Up! An Experimental Project on Design for Social Innovation and Urban Regeneration.

The research aims to share the results from the “Warm Up” Workshop—an experimental project held by PhD Product Design students from Sapienza University of Rome in collaboration with St. Petersburg University (SPbU)— involving students from SPbU’s Graphic Design Master Degree Program. The objective is to apply the topics of Design for Social Innovation and Design for Public Space to investigate the opportunities for new sociability in the social context of Vasilyevsky Island in St. Petersburg. The experimental aspect of the workshop is due to the fusion of methods and approaches typical of Product Design, such as human-centered design (HCD), and the Avant-Garde heritage of the Russian School. By illustrating their concepts of products/services, the students have developed a new practice within the fields of Product Design and User Experience. The final result is to serve a hypothetical urban regeneration in terms of Social Innovation, designing the user experiences as storyboards with the classical structure of “before and after” that would narrate the final change in users’ behaviors
