Breed affiliation features of honey bees (Apis mellifera) in the Novgorod region
Authors: Solovev V V 
Published: December 2020

Abstract
The article discusses the problem of biodiversity conservation, on the example of honey bees (Apis mellifera) in the Novgorod region of Russia. The work examines the local bees breed affiliation. The regional population of the Central Russian (Central European) breed has been indigenous to this territory. The author analyzes the natural conditions of the region in which it was formed and to which it is well adapted. Due to the anthropogenic factor and appearance of man-bred new breeds, the local population began to disappear, giving way to crossbred bees. The study finds out the breed genes prevailing in their modern population and whether the aboriginal Central Russian bees survived in the region. We indicate the morphometric breed features of the bees in the region, find the differences between the bees of various regions, analyze the reasons of these differences. It becomes obvious that pure-bred Central Russian bees practically did not survive. The bees of the Carpathian (Apis mellifera carpathica), Krainsky (Apis mellifera carnica) and local Central Russian (Apis mellifera mellifera) breed had the greatest influence on the formation of the modern honeybee population in the region. Unfortunately, this situation can be considered as an example of natural biodiversity reduction, which threatens local biocenoses, especially given the important role of honey bees in them.

Published: December 2020

Abstract
In the Novgorod region, the effectiveness of the integrated use of new microbiological preparations of Azotovit, Phosphatovit and mineral fertilizers has been investigated. The purpose of the experiment was to increase the yield of green mass of oatmeal mixture. Field experiment took place in 2017-2019 on sod-podzolic light loamy, clay-laden soil. Of the varieties recommended for cultivation in the North-West region, the following objects of research were used: spring vetch Lyudmila and oats of spring variety Borrus. Three methods of applying micronutrient fertilizers were tested: presowing treatment of seeds; foliar treatment in the phase of branching the wiki and tillering of oats; seed treatment presowing + foliar in the phase of branching the vetch and tillering of oats on two backgrounds of mineral nutrition - background 1 – N82P105К70 and background 2 – N41P53К35. The highest yield of green mass of oatmeal mixture (on average over 3 years) – 42.4 t/ha (6.8 t. units/ha) and digestible protein of 0.85 t/ha were obtained with a dose of mineral fertilizers per calculated yield N82P105K70 during seed treatment before sowing with microbiological fertilizers (Azotovit, Phosphotovit), as well as spraying the ground vegetative part of the vetch (in the branching phase) and oats (in the tillering phase). Doses: Azotovit –1.0 l/ha + Phosphotovit – 1.0 l/ha. At the same time, the energy intensity of production of one ton of feed units in this embodiment was 2.2 GJ. In addition, energy efficiency was 4.7 units, and the increase in soil energy potential was 15 GJ/ha.

Published: December 2020

Abstract
The authors conducted research on the effect of the olin probiotic on biochemical and indicators of the natural resistance of the quail of the Pharaoh breed. Changes in the morphological parameters of quail blood were noted (an increase in the number of red blood cells by 5.12-5.76% was observed in the blood, an increase in the amount of hemoglobin was also noted). No changes in the numbers of leukocytes and platelets were detected. The strengthening of humoral factors of natural resistance was facilitated by the introduction of a probiotic in the quail diet (lysozyme activity of blood serum was higher than the control values by 12.72%, bactericidal activity - by 7.27%). When analyzing the results of the studies, it was noted that the indicators of cellular immunity increased, a significant number of indicators significantly increased in the blood serum of quail from the experimental groups. Indicators such as poultry safety increased by 4.00-5.05%. The conducted studies convincingly proved the pronounced positive effect of olin on the functional state of the quail organism.

Authors: Toshkina E A 
Published: December 2020

Abstract
The herbage of rapeseed is a valuable feed with a high protein content, as in legumes. It is widely used in the green conveyor system, as a silage crop and for grazing when regrowing after mowing. In many countries with developed agriculture, there is a tendency to increase the area occupied by rapeseed. The correct selection of spring rapeseed varieties is crucial for their successful cultivation. According to the results of our research, the Oredezh 4 rapeseed variety showed itself to be fast-growing, and its mowing ripeness came on the 37th day. A higher yield compared to other varieties on average for two years of research provided a variety of spring rapeseed Oredezh 2.

Published: December 2020

Abstract
In the article the results of a statistical analysis of the effectiveness of using modern technical equipment in crop production are presented. The analysis of data of Federal State Statistics Service on the technical condition of the agro-industrial complex of the Russian Federation (APK RF) and agricultural organizations of the regions and republics of North-Western Federal District (SZFO) indicates that, against the background of an increase in the power support for labor in agriculture, a constant decrease in its energy supply with appropriate technical equipment is observed. An increase in quality of crop products is largely determined not only by the agricultural technologies used, but also by domestic technical resources that are in service in the agricultural sector of the Russian Federation and whose quality parameters and after-sale service need to be cardinally improved.
Creation of specially protected natural territories as a factor of sustainable development of the territory
Authors: Vasilieva G V 
Published: December 2020

Abstract
The article considers the issues of a comprehensive environmental survey of a territory promising for the creation of a regional nature monument “Batutinka River Valley and Lowland Marshes in its Basin”. Giving the territory the status of specially protected natural territory (SPNT) will make it possible to carry out measures for its protection, conduct research and environmental monitoring, as well as prevent unauthorized use of natural resources. The rationale for the concept is due to the presence of rare and endangered species of plants, mushrooms and animals (at least 23 objects of flora and fauna listed in the Red Book of the Russian Federation, Red Book of the Novgorod Region) and their places of growth (habitat). The profile of SPNT can be assessed as integrated (landscape), designed to preserve and restore natural landscapes; hydrological, designed to preserve and restore valuable water bodies and ecological systems, especially swamp massifs; biological, designed to preserve and restore rare and endangered species. Obviously, the listed groups of objects are diverse, interconnected, large-scale, have independent value, but their combined value is higher. They are components of a single natural-territorial complex, the preservation of which requires a systematic approach.

Published: December 2020

Abstract
A methodology based on statistical methods for optimizing multicomponent compositions is applied for meat product recipes design. Using raw materials of animal and plant origin, virtual arrays of input variables (raw materials) are developed and chemical (protein, fat), mineral and vitamin compositions are calculated for each data array. The calculation of balance and rationality of the amino acid composition in the feedstock is established by clustering method. As a result, the recipe of cooked sausage based on raw materials of plant and animal origin is developed. The optimal recipe for the developed meat product has a high utilitarian coefficient (0.856), the amino acid rate of the limiting amino acid is 0.87. The manufactured prototype is distinguished by high organoleptic characteristics (average organoleptic indicator – 4.8 points). The finished product yield to the unsalted raw materials mass is equal to 120.3%.

Published: December 2020

Abstract
To achieve a balanced composition of the product in terms of nutritive value, many researchers recommend combining meat raw materials with vegetable components. The paper presents a technique to optimize the formulation of minced meat semi-finished products developed by mathematical modeling. The main components of semi-finished products are broiler chicken meat, egg melange, and onion, protein-fat emulsion made of chickpea flour, sunflower oil and water. Optimization was aimed at obtaining the ratio of the components to meet the requirements established for nutritive values. At the same time, the recommended amount of vitamin and mineral for adults and the requirements of normative documentation for the quality of semi-finished meat products were taken into account. The target function was the protein content to obtain its maximum value. The optimized formulation obtained was used to make samples of meat semi-finished products, and sensory indicators were evaluated. The results showed that addition of chickpea flour affected the product color. Thus, we can conclude that mathematical modeling is an efficient tool to fabricate a product with desired properties. A combination of raw materials of vegetable and animal origin allows development of nutritionally balanced formulation.

Authors: Zykova I V , Isakov V A 
Published: December 2020

Abstract
The study was conducted at the biological treatment facilities of Veliky Novgorod. It has been established that the main percentage of metals is contained in the organic component of the conditionally solid phase of excess activated sludge. Based on the study of the elemental composition of the excess activated sludge, it is concluded that organic compounds containing aromatic, aliphatic and amine-containing functional groups are very diverse in the excess activated sludge. Main classes of substances making up the excess activated sludge are established. The mass fractions of the main classes of organic compounds established by the rational method are in good agreement with the analysis of the main classes of organic compounds that make up the excess activated sludge of biological treatment plants. The main compounds making up the inorganic component of the conditionally solid phase of excess activated sludge are determined. The study reveals a large variety of both organic and inorganic compounds in the excess activated sludge, which are able to bind heavy metal ions from aqueous medium due to physical and chemical interactions.

Authors: Zykova I V , Isakov V A 
Published: December 2020

Abstract
The aim of this study is to select a phytoremediation plant for cleaning sludge beds of biological treatment plants from heavy metals. The study was conducted on sludge beds of biological treatment facilities of Veliky Novgorod with a sludge retention time of 1 year and 15 years. It is established that the forms of metals in the sludges and wastewater sludge depend on the nature of the metal. Manganese (II) predominantly binds to compounds that make up sludge and wastewater sludge by the ion exchange mechanism, copper (II) – by the complex formation mechanism, zinc (II) – is codeposited with calcium and magnesium carbonates, manganese (IV) and iron hydroxides (III). Six selected plants were analyzed (bedstraw, cow vetch, field daisy, silverweed cinquefoil, base vervain, winter cress), those growing on sludge beds with a sludge retention time of 15 years, for the content of copper (II), zinc (II) and manganese (II) in different parts of plants. The phytoremediation plant was selected according to the indicators of the coefficient of biological accumulation (coefficient of biological accumulation) and translocation factor. It has been established that the bedstraw can be called a universal phytoremediation plant, in the absence of significant sludge contamination with copper (II), it is most preferable to use base vervain. Selected phytoremediation plants can be used for artificial planting on sludge beds in order to further use these beds as fertile lands.
Study of the adsorption of heavy metal ions from binary and multicomponent solutions by ceramic chips
Authors: Zykova I V , Isakov V A 
Published: December 2020

Abstract
The adsorption of heavy metal ions from binary solutions was studied using Co (II) as an example in the concentration range from 1 to 50 mg/dm3 and the adsorption of heavy metal ions from multicomponent solutions using Co (II), Ni (II) and Cu (II) by fractions of ceramic chips of 0.5-1.0 mm and 1.0-2.0 mm. It was established that the value of the ultimate saturation of Co (II) ions with ceramic chips depends on the pH value. The maximum value of the ultimate saturation for Co (II) ions is reached at pH = 9, the smallest – at pH = 3. An increase in temperature from 273 to 353 K leads to an increase in the ultimate saturation for Co (II) ions. Experimental data on the sorption of metal ions from multicomponent solutions show that the rate of achievement of the ultimate saturation of the sorbent in a metal depends on the value of the ionic radius. The ultimate saturation limit for a metal at the same concentration of metals and the presence of other metals is greatest for Cu (II), the smallest for Co (II). The results of the study indicate the high efficiency of ceramic chips as a sorbent of heavy metal ions from wastewater of various industries, which indicates the possibility of practical use of ceramic chips for wastewater treatment from heavy metals, especially taking into account the availability and the possibility of using it without regeneration with recycling in production pigments.

Published: December 2020

Abstract
The article studies petrochemicals and phenols adsorption in static and dynamic conditions from model petrochemical solutions. It was established that the adsorption of resorcinol occurs in micropores by volumetric filling, this process is best described by the Dubinin-Astakhov equation. The adsorption of petrochemicals occurs on the sorbent surface, forming a monolayer, this process is best described by the Langmuir equation. Based on the kinetic curves of petrochemicals and resorcinol adsorption, DEC (dynamic exchange capacity) and FDEC (full dynamic exchange capacity) have been calculated for activated carbons and fibrous sorption material. Using the Shilov equation, kinetic constants of the adsorption dynamics for resorcinol and petrochemicals on various sorbents are calculated. The study proved the promising use of sorbents for wastewater treatment of various industries.

Published: December 2020

Abstract
In this study, copper oxide nanoparticles (CuO NPs) were green synthesized using the leaf extract of Momordica cochinchinensis (Lour.). Various characterization techniques such as Energy-dispersive x-ray spectroscopy (EDS), Ultraviolet Visible (UV–vis) Spectroscopy, x-ray diffraction (XRD), Transmission Electron Microscopy (TEM) and Fourier-transform Infrared (FTIR) Spectroscopy were utilized to study the formation of CuO NPs. DLS and TEM analysis revealed the formation of sphere-shaped CuO NPs with mean particle size of 56 nm. Additionally, the prepared CuO NPs were incubated with Hepatic (HepG2) cells to check their cel viability and evaluate the formation of reactive oxygen species (ROS). The results of the current work exhibited a concentration-dependent decline in the viability of HepG2 cells with half maximal inhibitory concentration (IC50) value of 75 μg ml−1. The cytotoxic effect of CuO NPs was responsible for the cell apoptosis as well as ROS induction in the HepG2 cells. Further, the prepared CuO NPs could act as possible chemotherapeutic agent for the treatment of liver hepatocellular carcinoma (HCC) in future.
N-Terminal Pro-B-Type Natriuretic Peptide and Longitudinal Risk of Hypertension
Authors: Nicoli Charles D , Plante Timothy B , Long D Leann , Judd Suzanne E , McClure Leslie A , Arora Pankaj , Cushman Mary 
Published: December 2020

Abstract

BACKGROUND
Hypertension is a common condition that increases risk for future cardiovascular disease. N-terminal B-type natriuretic peptide (NT-proBNP) is higher in individuals with hypertension, but studies of its association with hypertension risk have been mixed.

METHODS
The REasons for Geographic And Racial Differences in Stroke (REGARDS) study enrolled 30,239 U.S. Black or White adults aged ≥45 years from 2003 to 2007. A subcohort included 4,400 participants who completed a second assessment in 2013–2016. NT-proBNP was measured by immunoassay in 1,323 participants without baseline hypertension, defined as blood pressure ≥140/90 or self-reported antihypertensive prescriptions. Two robust Poisson regression models assessed hypertension risk, yielding incidence rate ratios (IRRs): Model 1 included behavioral and demographic covariates and Model 2 added risk factors. A sensitivity analysis using a less conservative definition of hypertension (blood pressure ≥130/80 or self-reported antihypertensive prescriptions) was conducted.

RESULTS
Four hundred and sixty-six participants developed hypertension after mean follow-up of 9.4 years. NT-proBNP was not associated with hypertension (Model 2 IRR per SD log NT-proBNP 1.01, 95% confidence interval 0.92–1.12), with no differences by sex, body mass index, age, or race. Similar findings were seen in lower-threshold sensitivity analysis.

CONCLUSIONS
NT-proBNP was not associated with incident hypertension in REGARDS; this did not differ by race or sex.
