Abstract
Research has been conducted on the effect of the Mycosoil drug on economically valuable traits of tomato of Anahit-351 and Lia varieties, as well as pepper of Hayk and Loshtak varieties. After seed treatment with the Mycosoil drug, seed germination of tomatoes increased by 1.9–2.9%, and of peppers by 4.2–4.4%. Mycosoil contributed to an increase in germination energy: for Anahit-351 tomato variety by 4.3%, and for Lia variety by 6.6%. The germination energy of Hayk and Loshtak pepper varieties increased, respectively, by 1.6–2.5%. For all tomato varieties, the yield gain varied from 9.2 to 9.6%, and for Loshtak pepper variety – 7.5 %. An increase in fruit mass was observed in tomatoes: within 20.6–23.1 g, and in peppers – 5.4–11.1 g. Both the number of seeds formed in one fruit and the mass of 1000 seeds increased. The increase in the number of seeds for tomato varieties ranged between 3.8–4.8 seeds, for pepper – 3.3–7.9 seeds per fruit, and the mass of 1000 seeds increased in the range of 0.5–0.6 g for tomato and 0.3–0.6 g for pepper. When studying the effect of Mycosoil on seedlings in tomato of Anahit and Lia varieties in the variant of Fusarium + Mycosoil, the FAM signal showed values of 20.05–25.40 and it was lower than with control + Fusarium (35.61–38.74).

Authors: Moroz M T , Samorukov V I 
Published: December 2020

Abstract
Currently, goat farming becomes a perspective sector focused on production of goat’s milk and its products. Volume of milk produced by goats is determined by three factors: genetic heredity; environmental conditions, animal welfare and care conditions; feeding quality. In order to increase the productivity of dairy goats, it is necessary to improve and optimize feeding rates as the feeding is an essential factor defining the development of milk productivity. Sound feeding practices result in goats producing more than1000 kg of milk containing up to 4.5% fat. This practice-oriented research is based on the decision to use the information and analytical systems “RATIONS” in order to calculate balanced rations for adequate nutrition of dairy goats. Particular attention was given to introduction of feeding rates adjusted to fulfill their nutrient requirements of Saanen goats in North-West District of Russia.

Published: December 2020

Abstract
Increase in oil flax seed production largely depends on the effectiveness of the integrated protection of crops. In this regard, in 2017 and in 2018, studies were conducted to investigate the development of diseases, pests and weeds in crops depending on seed treatment with the bacterial preparation Flavobacterin at the small experimental field of the Department of Plant Production named after I. A. Stebut. The study results showed that inoculation with the biofungicide Flavobacterin is recommended before sowing for effective control of diseases in oil flax crops and in order to obtain a stable yield of high quality seeds at the level of 2.0 t/ha. This agrotechnical technique increases biological effectiveness by 72% against white rot, 87% against verticillium wilt and by 51% against blackspot. The biological preparation does not affect the development of pests and weeds in oil flax crops. In this regard, a system of weed and pest control in oil flax cultivation in the conditions of Leningrad region should be developed.

Published: December 2020

Abstract
Antibiotic resistance and side effects of drugs are the current concerns of mankind. Therefore, studies aimed at finding and creating new drugs with antibiotic activity from plant materials are of high relevance. The authors formulated the composition of an ointment that contains extracts from Cetraria islandica (Icelandic moss), sphagnum and propolis for treatment of purulent wounds, and determined its pH and bioavailability in vivo. The antimicrobial activity of the ointment was studied on experimental animals. To analyze the morphological features of the wound process, three groups of animals were formed: group 1, control without treatment; group 2, treatment of the wound with Levomekol ointment; experimental group 3, treatment of the wound with ointment that consists of Icelandic moss, sphagnum and propolis. Each group included 10 animals. The ointment for treatment of purulent wounds was developed on lipophilic base with optimal pH of 5.3, antibacterial activity against both gram-positive and gram-negative microorganisms, and it can be used in phases 1 and 2 of the wound process. It has a more pronounced therapeutic effect compared with Levomekol ointment, and facilitates earlier regeneration.

Published: December 2020

Abstract
The study describes the characteristics of protein metabolism in turkeys of different genotypes and age. It is established that poults during industrial cultivation were physiologically healthy, and the studied parameters fluctuated within normal limits. At the same time, the magnitude of the blood parameters depends on the age of the bird and the genotype determined by both the breed and crossing. The protein metabolism intensity determining the concentration of the total protein and its fractions in the blood of poultry, the activity of transamination enzymes (AlAT, AsAT) does not so much depend on age, but on the birds genotype. The highest level of protein parameters is found in the blood of heavy cross Hybrid Converter. At the same time, the rate of growth and development of their body is associated with the exchange of albumin and the ways of using free amino acids to cover its energy consumption. Therefore, turkey poults of this cross are superior to their analogues in terms of albumin (by 9.54%), activity of AsAT (by 1.61–6.93%) and AlAT (by 2.77–5.23%).

Published: December 2020

Abstract
The high quality of the services provided is a component that determines the competitiveness of laboratories. It is necessary to update laboratories in modern conditions of the development of scientific and technological progress. Another important task is to ensure control of the quantitative content of toxic elements, the introduction and application of fast and reliable methods of their analysis. Analysis of monitoring the quantitative content of toxic elements in food samples confirms the need for analytical express control; its implementation allows tracking the content of potentially hazardous elements in products and preventing their influence on human health. The analysis of monitoring results for 2017-2019 showed the predominant ranges of toxic elements’ concentrations in various categories of products. It was revealed that when the quantitative content of cadmium is detected, the maximum number of test results falls within the range of less than 0.001 mg/kg. In the case of the quantitative content of lead detection, the maximum number of test results falls within the range of less than 0.01 mg/kg; in the case of detecting arsenic, the range is less than 0.02 mg/kg.

Published: December 2020

Abstract
The rheological feature of vegetable-fruit smoothies is a non-stratified, partially heterogeneous texture that fits seamlessly into the concept of a smoothie as a healthy food drink with minimal heat treatment, containing a large number of biologically active substances, primarily vitamins, provitamins, polyphenol substances, as well as dietary fiber - the so-called “superfood”, the effectiveness of which has been proven in vitro. At the same time, the stability of such drinks is a serious technological problem requiring new approaches to the solution. The aim of the study was to study the possibility of using the amylolytic enzyme preparation Termamil 2XL to achieve the stability of the rheological characteristics of the pumpkin-sea buckthorn smoothie, which together provide a stable texture of the drink. It is shown that the use of coarse pumpkin pulp does not allow to achieve the desired result in terms of stable rheological characteristics, since the smoothing separation begins almost immediately after preparation. The possibility of using enzymatic hydrolysis of pumpkin starch, which causes a stable framework due to starch grains in tissue cells, has been established to stabilize the rheological properties of fruit and vegetable smoothies and increase the consumer characteristics of the drink. It is proved that the use of the enzyme preparation Termamil 2XL in a dosage of 0.04% and a treatment time of 60 minutes leads to the production of a stable pseudoplastic fluid with a homogeneous structure and a maximum separation of the liquid phase not exceeding 3% within 24 hours.

Published: December 2020

Abstract
The problem of iodine deficiency for most residents of the Russian Federation remains relevant for many decades. The situation is aggravated by the fact that with an inferior monotonous diet, a deficiency of proteins, vitamins and trace elements occurs side by side. To solve this problem, we can choose the path of enrichment of the product with organic iodine, as well as vitamins and vegetable protein. It is economically feasible to provide a combination of raw meat with cheaper functional components that are full in amino acid composition. The possibility of using the kelp preparation in the production of food products based on meat raw materials with the aim of correcting the iodine deficiency of the population in ecologically unfavorable areas was investigated. We used a natural iodinating dietary supplement - a hydrated preparation of Japanese kelp, which is a source of dietary fiber. A study of the process of the influence of this additive on the functional and technological properties of minced meat systems shows the promise of the use of this drug in the production technology of meat food products. In addition, the rational use of meat raw materials (fatty pork and spike fat) in combination with vegetable components (Dantex soybean texturate) and Japanese kelp in an optimal dose of 5% has a number of economic advantages compared to similar products.

Authors: Semkiv M V , Lukashik E E 
Published: December 2020

Abstract
At the current stage of dairy cattle breeding, one of the most pressing problems is monitoring of the feed base, which includes the procurement of high quality feed. Solution of this problem also requires a focus on ration formulation, since unbalanced feeding can cause metabolic disorders, which ultimately affects realization of the genetic potential of dairy breeds. In this regard, to increase the production of cows, it is necessary to constantly improve and optimize their feeding rates, since feeding is the most important factor to advance dairy cattle breeding. Appropriate feeding ensures cow production amounting to 6,000–8,000 kg of milk and more, with a milk fat content of 3.7–4.2%. The paper provides data on monitoring of the state of the feed base on the studied farm to ensure adequate feeding of cows. Within the stated problem, the study also focuses on the analysis and assessment of the rations of cow feeding with regard to the physiological state of the animal, which was confirmed through the use of the targeted ration. The basis of the practice-oriented study was the decision to use the information and analytical system RATIONS to calculate balanced feed rations for adequate feeding of dairy cows. In the future, the farm needs to pay special attention to introduction of adapted feeding norms for black-motley cows to satisfy their need for nutrients.

Authors: Shah A J , Jayprakash V , Vesmawala G R 
Published: December 2020

Abstract
This paper outlines various vibration-based methods for detecting and locating damage in mechanical and civil structural systems. The basic premises of these methods are that any changes in physical characteristics (mass and stiffness) of the structure will induce detectable changes in the modal properties of the structure (natural frequency, mode shape and damping). A comparative study of eight extensively used damage identification methods is done on a simulated simply supported beam to demonstrate the validity and effectiveness. The outcomes of various methods are compared in terms of damage detection and localization under single and multiple damage scenarios.

Abstract
Laminated composite plates are well known structural member since last four decades because of its high stiffness and strength to weight ratio. Usually this type of structural members is subjected to partial biaxial loading during their functioning. For better safety and stability of structure, analysis of these structural member in that condition of loading is necessary. In this present analysis buckling response of laminated composite plates under biaxial partial in-plane loading is examined and effect of various parameters like aspect ratio, stacking sequence, fiber orientation and plate thickness ratio of nondimensionalised critical buckling load (NCBL) are revealed. A MATLAB program is developed higher order shear deformation theory based on finite element method for buckling analysis of laminated composite plate. Efficiency of the program is checked by comparing the result of the present work with that of already published which shows good favour of later one.

A Review on Identification and Elimination of Ovality in Circular Holes During Manufacturing of Hollow Cylindrical Components
Authors: Mane Shrinath , Dabir Jamil 
Published: December 2020

AbstractThis review paper aims toward the investigation of manufacturing process of hollow cylindrical component to identify the defects causing ovality in circular holes. The manufacturing refers to the processes required to convert raw material into the final product which may include casting, machining, welding, finishing, heat treatment processes and ends with final inspection to check for defects. Mostly the circular holes of hollow cylindrical components show ovality after manufacturing, exceeding tolerance values and such defect leads to poor fittings. After careful study of the variety of research papers related to ovality, it was found that the ovality may occur due to component characteristics or due to defects in manufacturing process of the component. The results of these research papers concluded that machining parameters, unbalanced workpiece, clamping pressure, clamping geometry and clamping technique influence the dimensional deviations and it can be prevented by improving the production with corrective techniques.
