    The article presents the results of analysis of the spatial arrangement of the wells on the unique slab from Srubna burial of kurgan field Tavriya-1 (Rostov region, Russia) by astronomical methods. At the slab revealed two interrelated groups of wells, one of which - in the form of a circle, is proposed to interpret how analemmatic sundial, and second group, consisting of disparate wells, as auxiliary astronomical markers of rising luminaries directions, to correct the position of the gnomon. Simultaneous location of both groups of wells on the same slab is a possible indication of one of the stages of development of the design features analemmatic sundial - setting movable gnomon and technology of measuring time with it. It may point to local origin, as the very idea of analemmatic sundial as well technology measurement of time with them. The article also describes the model analemmatic sundial, hour marks which in many cases coincide with the wells arranged in a circle, particularly in a working range from 6 to 18 hours. In the study proposed a method which can identify moments of solstices and equinoxes in ancient times with the help of the gnomon of analemmatic sundial and mobile gnomons, installed in wells belonging to the second group. The opportunity of use analemmatic sundial as moondial in a full moon night. Slab with two groups of wells is proposed to consider, as the oldest astronomical instrument discovered in the Northern Black Sea coast, which allowed to observe the apparent motion of the Sun and the Moon and allowed measure the time during the day, using analemmatic sundial and at night during the full Moon - with the help of moondial. Keywords: analemmatic sundial, moondial, srubna burial, slab, wells, cupped depressions, gnomon, model, technology, astronomical methods, archaeoastronomy.Comment: Published version of the articl

    Insufficiently studied and at the same time promising is the use of an acidophilic starter for making the bakery products designated as military personnel's food. An acidophilic sourdough starter is a mixture of the species and strains of yeast and lactic acid bacteria grown on the basis of saccharified pregelatinized flour and specially selected in certain proportions. The study aims at obtaining a dehydrated biopreparation of fermented pregelatinized flour for bakery production using the strain Lactobacillus helveticus H10 (dry fermented pregelatinized flour) and its application in the technologies of bakery products made from rye and a mixture of rye and wheat flour. The composition of the nutrient mixture for dry fermented pregelatinized flour has been optimized in terms of rheological, biotechnological and microbiological indicators. It has been found that fermented pregelatinized flour with a 50% content of a starter has the least viscous structure, which allows us to dry the sample faster and to preserve lactic acid bacteria. It has been found that the sample prepared using rye wholemeal flour was characterized by a higher content of amine nitrogen (by 15%), volatile acids (by 29%) and mass fraction of sugar (by 27%) compared to the sample of fermented pregelatinized flour made using rye bread flour. It has been revealed that microorganisms are destroyed least during convective drying. The main technological parameters for making dry fermented pregelatinized flour that provide stable biotechnological and microbiological properties have been developed: a drying temperature of 40–45°C for 170–200 min with an air flow rate of 1.5–1.8 m/s above, 0.3–0.5 m/s below, 0.8 m/s on the right and 0.1–0.15 m/s on the left. A complex technology of long-life rye-wheat bakery products has been developed

    Introduction.  Premature ejaculation (PE) is the second most common male sexual dysfunction with a significant negative impact on quality of life. A significant number of conservative and surgical methods for the treatment of PE are proposed, but their effectiveness and, in some cases, safety, remain the subject of discussion.Objective. To study the effectiveness of pulsed radiofrequency impulse neuromodulation (RPN) with different modes on the penile dorsal nerve in treatment of patients with premature ejaculation.Materials & methods. Two groups of PE-patients participated in a prospective multicenter study: Group 1 — 11 patients aged 22 – 34 years; Group 2 — 12 patients aged 23 – 34 years. Group 1 received pulsed RPN at a temperature of 42°C, a stimulation frequency of 2 Hz, 45 V, and a duration of 180 seconds; in Group 2 — pulsed RPN at a temperature of 50 °C and the same frequency and duration of stimulation as Group 1. All patients before and after treatment measured intravaginal ejaculation latency time (IELT) and completed a premature ejaculation profile (PEP). The results were evaluated after 30 days.Results. In both groups, there was a statistically significant increase in IEDT and PEP. Thus, in Group 1, IELT increased from 58 to 101.9 seconds, PEP from 3.8 to 12.6 points. In Group 2, IELT increased from 66.5 to 210.9 seconds, PEP from 3.2 to 12.6 points. At the same time, in Group 2, IELT increased by 107% more than in Group 1. No significant side effects were observed in both groups.Conclusion. RPN appears to be a very promising treatment for premature ejaculation, as it is a minimally invasive, safe, and reversible procedure. The technique of influencing the penile dorsal nerve at an electrode temperature of 50 °C compared to 42 °C seems to be more effective, however, additional studies are needed

    The article provides new information about the syntaxonomic diversity of the aquatic vegetation of ponds in the Saratov region. Our studies were carried out in 2012-2014 in 15 districts of the Saratov region. The study of ponds vegetation was carried out through the detailed analysis with thorough description of aquatic vegetation, in accordance with common practice in the gidrobotanical methods. During the period of the study more than 3 000 gidrobotanical descriptions were made. The classification of plant communities was based on dominant and determinant approach to the selection of aquatic vegetation. The classification of the new association for the area was based on the comparison of our data with the data obtained by E.S. Shishkina. The community of 23 new associations is described. The prodromus of aquatic vegetation taking into account the new information is presented. The new association of formations Ceratophyllum submersum, Ceratophyllum tanaiticum, Batrachium trichophyllum, Potamogeton crispus and Najas major are described. The new information about one formation – Caulinia minor – is presented. The syntaxonomic diversity of aquatic vegetation of ponds of the Saratov region is premature. It is necessary to continue research on the vegetation of these interesting objects, especially in the distant Saratov districts, where there are many brackish ponds, vegetation of which is significantly different from fresh pond vegetation and fresh water. Key words: aquatic vegetation, ponds, Saratov region, syntaxonomy, diversity, associations, formations, hydrophytes

    On the basis of plastically deformable material such as two-phase heterogeneous environment built filtration model of plastic deformation. The basis of this model is based on the laws of conservation of momentum and mass for each component, the equation of state and boundary conditions. The first component of the environment is resilient, she is responsible for structural transformations, and the second plastic component, it is not associated with structural transformations. For traveling waves the dispersion equation. Found a critical wavelength at which the instability occurs. Critical wavelength coincides with the size of the localization regions.На основе представлений о пластически деформируемом материале как о двухфазной гетерогенной среде построена фильтрационная модель пластической деформации. В основу этой модели положены законы сохранения импульса и массы для каждой компоненты, уравнения состояния и граничные условия. Первая компонента среды является упругой, она отвечает за структурные превращения, а вторая компонента пластическая, она не связана со структурными превращениями. Для бегущих волн получено дисперсионное уравнение. Найдена критическая длина волны, при которой наступает неустойчивость. Значения критической длины волны совпадает с размерами областей локализации.Исследование выполнено за счет гранта Российского научного фонда (№ проекта 15-12-00010)
