Treasures were discovered during archaeological research of the Idnakar hillfort in 1976–1999. Two treasures were found on the middle square of the hillfort. The third treasure was found on the territory of internal fortifications, another one – outside the middle line of fortifications. Patterns in the location of the treasures relative to the planning objects are not revealed. The nature of the complexes is diverse. In general, jewelry dominates. Two treasures contain metal ingots and unfinished products. This indicates their local production. A treasure containing imported vessels is an important source for the analysis of trade and economic relations of the medieval population of the Cheptsa River Basin. Jewelry from treasures is dated to the period of 10th –13th centuries. Similar products were found in the materials of medieval monuments of the Finno-Ugric population of Eastern Europe. Data on the elemental composition of metal products from treasures are published. Metal research was carried out by Bazhen Evgenievich Pushkarev, Candidate of Technical Sciences (Scientific Center for Metallurgical Physics and Materials Science, Udmurt Federal Research Center, Ural Branch of the Russian Academy of Sciences). Earrings and ritual bowls were made of silver. Pendants, jewelry items and metal ingots were made of copper alloys (pure copper, bronze, brass). Alloy formulations vary, which is typical of the medieval metal of the Cheptsa River Basin.

Chrysanthemum is one of the leading crops of commercial floriculture. Within garden groups and classes, chrysanthemums are divided according to cultivation methods, shape and size of the inflorescences. For varieties grown on a cut, a group of large-flowered (with a diameter of inflorescences of 12-25 cm), small-flowered (4-10 cm) chrysanthemums and santini (from 2 to 4 cm) is distinguished. Having a limited assortment of chrysanthemum garden, in a humid subtropical climate, it is possible to form a largeflowered (single-headed, disbud) and small-flowered (spray) cut. The purpose of the research was to study the peculiarities of formation of large-flowered chrysanthemums (Chrysanthemum×hortorum Bailey) to obtain cut in the humid subtropics of Russia. The objects of research were large-flowered and small-flowered varieties of chrysanthemums of foreign and domestic breeding. The studies were carried out in the open ground of the Department of Agricultural Engineering and Nursery of the Federal Research Center the Subtropical Scientific Center of the Russian Academy of Sciences. Scientific research was carried out according to the methodology of State variety testing of agricultural crops and the methodology of testing for distinctness, uniformity and stability of chrysanthemum (perennial) Chrysanthemum spec. ‘Sevan’, ‘Baltica White’, ‘Granada’ and ‘Zembla Brasil’ are large-flowered varieties, which have bush peduncles of good commercial quality with large inflorescences of saturated shades. In turn, from small-flowered garden forms ‘Zembla White’, ‘Annecy White’ and ‘Westland Regal’ with regular pinching, you can grow a large-flowered cut of chrysanthemums. It was revealed the relationship between biometric characteristics in order to determine additional diagnostic features of the possibility of the formation of large-flowered inflorescences. So, the diameter of the inflorescence is the most significant parameter for research which has significant positive relationships with the diameter of the peduncle and the length of the extreme ray flower. It will allow determining the possibility of growing the variety in one form or another, depending on the needs of production, at the initial stages of introduction and variety study.

Copper Tolerant

The corrosion of copper and copper alloys in a marine environment is of great concern because of their widespread use in heat exchangers and steam condensers in which natural seawater is the coolant. It has become increasingly evident that microorganisms play an important role in the corrosion of a number of metals and alloys under a variety of environments. For the past 15 years the use of SEM has proven to be useful in studying biofilms and spatial relationships between bacteria and localized corrosion of metals. Little information, however, has been obtained using TEM capitalizing on its higher spacial resolution and the transmission observation of interfaces. The research presented herein is the first step of this new approach in studying the corrosion with biological influence in pure copper.Commercially produced copper (Cu, 99%) foils of approximately 120 μm thick exposed to a copper-tolerant marine bacterium, Oceanospirillum, and an abiotic culture medium were subsampled (1 cm × 1 cm) for this study along with unexposed control samples.

Intermittent Lighting Improves the Efficiency of Artificial Insemination in Cage Housed Laying Hens Kavtarashvili A.Sh., Kolokolnikova T.N. Federal Scientific Center “All-Russian Research and Technological Poultry Institute” of Russian Academy of Sciences Omsk Agrarian Scientific Center Summary: The effects of different lighting regimes on the oviposition schedule, productive performance, and reproductive efficiency in cage housed laying hens of layer parental flock (Hisex White-R) were studied; the reasonable regime of artificial insemination (AI) under intermittent lighting is proposed. It was found that intermittent lighting regime 1L:4D:4L:1D:4L:10D compared to the constant lighting significantly alters oviposition schedule: under this regime 82.3% of all daily eggs were laid until 9 am (vs. 66.6% in control). This regime and AI at 10 am improved the productive and reproductive performance compared to control (constant lighting 16L:8D and AI at 12 am): mortality by 1.9%, egg production per initial hen by 3.8%, egg weight by 1.1%, percentage of eggs suitable for incubation by 1.9%, egg fertility by 0.9%, hatchability by 2.3%, hatch of chicks by 2.9%, feed conversion ratio (kg of feed per 10 eggs) by 5.3%, the expenses of electric energy for lighting (per 1000 eggs suitable for incubation) by 54.5%.

The article studies the possibility to use glycerol as cryoprotectant, instead of dimethylsulfoxide for cryopreservation of sperm of inconnu ( Stenodus leucichthys Gueldenstaedtii, 1772). Investigations were carried out from 2015 to 2016 in the laboratory of the Southern Scientific Center, Russian Academy of Sciences, on the basis of the Astrakhan State Technical University. The material collected on the Alexander sturgeon hatcheries (the Astrakhan region) in the spawning period. Native sperm of 6 male inconnu species was used as a control means. The semen quality was determined in terms of moving activity (life time) of sperm after its activation by water. As the cryoprotectant there were used: base solution - 80%, sucrose - 1.71 g/l, mannite - 0.98 g/l, yolk - 10%, dimethylsulfoxide - 10% and base solution - 87%, sucrose - 1.71% g/l, mannite - 0.98 g/l, yolk - 10%, glycerol - 3 variants: 3; 5 and 10%. In order to provide the most complete penetration of cryoprotectants into the cells there were used electrostimulation of cell membranes. Equilibration time was 5 and 15 minutes. Thawing semen was performed in a water bath at a temperature of 38-40°C. For removing protectors from cells there was chosen a saline solution (0.7% NaCl) as isotonic solution. In tests using dimethylsulfoxide life activity of sex cells was 2 times lower than in tests with glycerol: 78 and 186.2 s at the end of equilibration and 52.3 and 128.9 s after thawing. Sperm showed maximum activity under 5% glycerol concentration during equilibration - 15 min. Concentration of 3% was insufficient, concentration of 10% was excessive, as it suppressed activity of sperm. Egg yolk which coagulated together with glycerol, making difficulty for observing, had to be excluded from the composition of cryoprotectant.
