Волосовская культура была распространена в центре европейской части России в позднем неолите - энеолите. Среди артефактов этой культуры на ряде стоянок представлены роговые стержни и изогнутые предметы неясного назначения. В результате проведенного авторами трасологического анализа установлено, что они являются составными частями ретушеров для обработки кремневых орудий. При этом изогнутые предметы были рукоятками, в паз которых вставлялись стержни, служившие рабочими частями этих орудий. Такая конструкция ретушера была оптимальной с функциональной точки зрения. Почти без изменений она дожила до этнографической современности. The Volosovo culture was spread in the center of the European part of Russia in the Late Neolithic-Eneolithic. The artifacts of this culture retrieved from a number of sites include antler rods and curved items of unknown functions. The tracewear analysis conducted by the authors established that these items are parts of composite retouchers used to treat flint tools. The curved items were handles with a slot into which rods used as working parts of the tools were inserted. This design of a retoucher was optimal from the functional point of view. It has survived into ethnographic modernity with almost no changes.

A comparative study of the phytochemical composition of the fruit of buckthorn berries of various varieties cultivated on the territory of the European part of Russia. Identified varietal patterns of accumulation of various groups of biologically active substances (BAS) with the fruits of this plant make it possible to recommend certain sorts for further development of new herbal medicinal preparations based on this medicinal plant material. So, from the point of view of the solvent used, «Nivelena» and «Botanical Flavor» can be considered the most balanced varieties for obtaining aqueous medicinal forms (infusions and broths) containing water-soluble BAS groups. To create the alcohol dosage forms (tinctures, including matrix homeopathic and extracts), the most suitable varieties can be considered «Rowan» and «Capital».

On the basis of author's graphical analysis method, the typification of lake ecosystems transformation scenarios depending on the size of lakes was carried out. It was confirmed that the type of transformation depends not only on size of the lake, but also on the landscape and climatic region in which it is located. The distinctive features of lake ecosystems transformation types in the European part of Russia and in Western Siberia were analyzed and compared.

The results of a sintaxonomical study of plant communities of the Yamozero lake (the North-East of the European part of Russia) are presented. The diversity of the aquatic and helophytic vegetation of the Yamozero lake consists of 16 associations and 2 communities of 6 unions, 4 orders and 2 classes of the floristic classification: Potamogetonetea (7 associations, 2 communities), Phragmito-Magnocaricetea (9 associations). Many of described associations are widely distributed in the Central and the Eastern Europe. Some associations have the boundaries of their ranges. Some communities include 2 rare species of regional level: Isoetes setacea and Sagittaria natans.

The paper provides the results of seven-year study of downy mildew on Skadovsky Zvenigorod Biological Station of Moscow State University (ZBS MSU, Moscow Region). A total of 29 species of Peronosporales (Oomycota) were revealed during the study. An annotated list of species is presented, among them Peronospora anemones is recorded for the first time for Russia, P. chelidonii and P. stachydis are new for the European part of Russia, 8 species are new for the Moscow Region.

The results of a syntaxonomical study of plant communities of the large lake Donty (North-East of the European part of Russia) are presented. The diversity of hydrophytic vegetation has been classified into 3 classes (Lemnetea, Potametea and Phragmito-Magnocaricetea), 5 orders, 8 alliances, 20 associations and 1 community. Subasso­ciation Scolochloetum festucaceae caricetosum aquatilis is new. Communities of associations Caricetum aquatilis, Equisetetum fluviatilis, Potamo—Nupharetum luteae, Potametum perfo­liati are mostly wide distributed, while these of Phragmitetum communis, Scolochloetum festucaceae ones are relatively rare as well as Lemno—Spirodeletum polyrchizae, Elodeo—Potametum alpini, Potamo—Nupharetum pumilae, Potametum praelongi and Scirpetum lacustris are very rare. Some communities contain 2 regional rare species: Scolochloa festucacea and Ranunculus lingua.

Functional Point

Canine plays an important role in the dento-maxillary system. From a functional point of view, it provides the canine guidance, by positioning it in the frontal area, has a role in facial aesthetics. It plays an important prosthetic role by having the longest root and one of the longest arcade teeth. Three molars represent the last teeth that erupt in the arches both in the jaw and in the mandible, which is why they remain the most frequently included.Canine incidence is quite common following the wisdom tooth. It can be unilateral or bilateral and is more common in the upper jaw. The canine may remain included at the vestibular, palatal or between the two bones. A separate entity is the incision of the canine in the edentulous mandible or jaw. The study included 213 cases with dento-alveolar pathology, of which 128 patients were selected with dental inclusion. Our study reports that the first three molars are frequent, followed by the canine as opposed to other studies conducted by Guzduz K in 2011 and Fardi A of the same year bringing the canines first (Fardi, Guzduz). Some studies attribute the first place to the superior canine in terms of frequency, but they are abstracted from the molar three inclusion that they consider as most frequently (Compoy). The most common tooth in inclusion is the third molar (lower and upper) followed by the upper canine; the most commonly affected are women for both canine and molar.

The paper describes the methodology and presents the results of the calculation of the spectral characteristics of the terrain for the territory of the Bolshezemelskaya and Malozemelskaya Tundra (the north of the European part of Russia). There are nine terrain clusters, differing in the topographic dissection pattern. Their geomorphological interpretation is given. Three clusters characterize mountainous and coarsely hilly terrain with the depth of dissection from 150 m and more. The others are low and elevated terrains with much lower depths of dissection (up to 50 m) and different patterns of interposition of landforms.
