Abstract
In this experiment, epoxy resin, fine hemp fibre, and cotton fibres were combined to create bio-composites. The weight percentages of hemp fibre (0, 10, 20, 30 wt. percent), cotton fibres (35, 25, 15, 5 wt. pewrcent), and epoxy resin have been varied to produce four composite mates. As per ASTM standards, composite specimens were prepared using the water jet machining process. Tensile, flexural, and impact tests were performed on the composite specimens in order to determine their mechanical properties and water absorption behaviour. Composites containing 20 wt.% fine hemp fibre in weight percentage showed significant improvements in tensile properties. Composites containing 30 wt% hemp fibre improve both flexural and impact properties, according to the test results.

Published: September 2021

Abstract
Battery safe necessitates preventing thermal runaway and its propagation. Aiming at the thermal runaway problem of pure electric vehicle lithium-ion power battery, a thermal runaway model for large-capacity lithium-ion prismatic batteries is developed. Two thermal abuse conditions: hot box and single-side heating are considered in the simulation. Corresponding experiments are conducted to verify the accuracy of the model. The results show that the gas generated by the decomposition of the solid electrolyte interface (SEI) membrane and the anode-solvent reaction triggered the pressure relief valve. The thermal runaway process of single-side heating has a temperature difference of more than 200°C, and thermal runaway may have occurred when the local temperature of the battery is normal. This lays a foundation for subsequent research and system development.
Exploration of Rain Gauge Quality Issues in Northern England

Published: September 2021

Abstract
The rain gauge, which is the preferred device for rain rate quantification, is susceptible to various types of errors. The problems of inconsistency and incompletion of rainfall time-series, in addition to data quality issues obstruct hydrometeorological analysis. Daily rainfall data from 30 gauges in Northern England were quality controlled by a double quality check procedure for the period 2006–2014 to solve any specific data quality issues. It emerged that fault readings happened only over a few days compared with the high percentage of missing data which could reach years. Thus, factors that impact gauges’ missing data were inspected. It was found that snowfalls, land cover-land use and bird distribution are the dominant factors that malfunctioning the rain gauge for long time periods, often producing successive missing days that could be extended months in total. However, when the missing data happened on separate days, then it seemed that high winds related with light rainfall resulted in drifting away the rainfall from the rain gauge and thus caused missing data. Moreover, the rainfall itself was not one of the major factors to malfunction the gauge, because the values of missed rainfall were not quite extreme to do this.

Abstract
The Ilmen Klint is a geologically formed landmark located in the Shimsky and Starorussky districts of the Novgorod region. Its location area is the western part of the southern shore of Lake Ilmen and covers the delta of the Lovat and Shelon rivers. A characteristic feature of the soils of the banks of the Psizha river is the presence of laminated dense crystalline yellowish-brown limestones. In the upper part of the Ilmen Klint, near Buregi village, brown limestones have formed. The modern vegetation cover of the Ilmen Klint has resulted from a long historical process and now continues to undergo changes. The main role in this is played by the human, their economic activities. In 2001, the Ilmen Klint was accorded the status of a Specially Protected Natural Area (SPNA) of the Novgorod region in order to preserve and study its natural diversity and maintain its ecological balance. The carried out floristic studies made it possible to describe natural habitats with a rich floristic composition and equity participation of Lathyrus pratensis L., Medicago falcata L.: Medicago lupulina L., and Anthyllis macrocephala L. species. The meadows and outcrop areas of the Ilmen Klint are characterized by a high diversity of rare species with certain patterns of meadow community development. At a high coastal slope level, there is a dry meadow with a herb-foxtail community. In addition, the participation of crop wild relatives (CWR) in natural plant communities of the Ilmen Klint territory is considered. Species of the Fabaceae L family are the main source of CWR here. Human well-being depends on the conservation of biodiversity and biological resources, particularly plant resources.

Published: September 2021

Abstract
The high genetic potential of productivity and a similar level of animal feeding underlie the intensive technology of rearing young animals for dairy cattle breeding. The realization of the genetic potential of dairy productivity of livestock largely depends on the efficiency of rearing young animals. Therefore, proper feeding of livestock is one of the main factors contributing to the maximum realization of this potential of animals. The conducted studies have shown that the breeding plants of the studied region successfully solve the issues of intensive cultivation of repair young animals. The increase in live weight of heifers allows for the first insemination at 16–17 months with the corresponding live weight. However, in the whole region, the data on the growth and development of heifers are significantly inferior to the indicators of breeding plants and the first insemination is carried out at 19 months and older. As a result of the conducted research, a plan for the growth of repair young animals was developed and the average daily live weight gains for the growing periods were recommended. The demand of reared young cattle for metabolic energy and crude protein is calculated.

Published: September 2021

Abstract
One of the main factors determining physicochemical and structural properties of the dry permeate of spray drying is lactose which is present in permeate as a basic phase. If lactose is in the β-form in a dry powder, the powder easily absorbs moisture from the atmosphere during storage, causing agglutination, clumping, and caking of the product. Prevention of negative consequences associated with increased hygroscopicity, is ensured by the directed crystallization of lactose in a condensed product before spray drying. The purpose of this investigation was to study the crystallization process of lactose in permeate under industrial conditions when using various seed materials. Results of the studies showed that the type of a crystal forming agentdoes not affect the size and shape of lactose crystals and the level of lactose crystallization. Seed material is of critical significance as it will ensure both a high level of crystallization and homogenous crystals which, in general, leads to an increase in melting temperature, due to a decrease in the proportion of amorphous lactose, as well as improves the drying process.

Abstract
Soybean meal (SM) is the main protein source for animals. However, certain anti-nutritional factors such as trypsin inhibitor, glycinin, raffinose, stachyose and others reduce its nutritional value, and inhibit the growth and development of animals. Fermentation of soybean meal is an economical alternative which improves nutritional properties of soybean meal due to both biodegradation of anti-nutritional factors, proteins, fibers, and probiotic and prebiotic production, which can subsequently improve taste and digestibility of nutrients. The purpose of this work is to study the effect of a selected consortium of probiotic microorganisms on the composition of fermented soybean meal (FSM). Experiments showed that the introduction of a mixed culture including strains Bacillus subtilis B7046, Aspergillus niger F1270, Saccharomyces cerevisiae Y4659, Lactobacillus plantarum K9 B5466 led to an increase in the content of easily digestible protein in the fermented soybean meal and a decrease in the content of anti-nutrional factors.

Published: September 2021

Abstract
Sugar beets are grown for sugar production. After harvesting, sugar beets are placed in closed storage for long-term storage. The main purpose of storage is to preserve sugar as much as possible in order to further ensure the profitability of processing beets for sugar. However, during storage of sugar beets, there is a rapid loss of moisture and weight. Beets, which have a weight loss of 13 … 17%, lose 5 times more sugar during storage than beets of good quality. One way to reduce the weight loss of sugar beet tubers is to use the magnetic field of a neodymium permanent magnet. Experimental studies on the treatment of sugar beet tubers with a magnetic field showed that the minimum weight loss of sugar beet tubers when treated with a negative magnetic field reached 15.3%, the minimum weight loss of sugar beet tubers when treated with a positive magnetic field reached 17.6%, and the weight loss of tubers sugar beet, not treated with a magnetic field, reached 25.6%. Thus, the nature of the influence of the magnetic field of a permanent neodymium magnet of positive and negative polarity on the weight loss of sugar beet tubers has been established.

Published: September 2021

Abstract
It was found that the processes of exchange of carbon compounds between the soil and the atmosphere are characterized by high variation in different periods of the annual cycle. It has been proved that CO2 emission, as well as the release and absorption of methane from the soil, is the main expenditure item in the balance of organic matter, which significantly affects the fertility and the level of productivity of agrobiocenoses. Soil fertility management and carbon gas cycle processes largely overlap. With an increase in the content of organic carbon from 0.55 to 0.98%, the loss of carbon dioxin and the absorption of methane compounds increase 1.5–4.3 times. A weak correlation was established between the release of carbon dioxin and the degree of soil cultivation (Kendall coefficient r = 0.23 at p = 0.05), seasonal dynamics of soil moisture r = 0,23 at p = 0,05) and a strong one (r = 0,87 at p = 0.000,2) with methane release / uptake dynamics. The same relationship was found between the dynamics of carbon dioxide release and the temperature of the soil layer 0–5 (Pearson’s coefficient r = 0.82–0.84 at p = 0.003–0.04), and 0-20 cm (r = 0.68–0.71 at p = 0.003–0.006).

Abstract
The economic recession amid the COVID-19 pandemic, the difficult socio-economic conditions of the Russian Federation associated with the introduction and distribution of functional food products are not only a factor in the formation of state policy in the field of healthy lifestyles., but are a necessary condition for the preservation of the health of the nation. The article discusses the problematic issues associated with the need to create sports nutrition products based on lentil, as plant materials rich in protein compounds. Sports nutrition (SP) is a specialized food product that compensates for the deficiency of missing protein substances, contributing to the rapid recovery of the body’s adaptive systems during periods of stress, both physical and immune. The analysis of the development of the sports nutrition market in the Russian Federation on the basis of marketing research of the agency “BusinessStat” is presented. Allows one to predict the prospects for the development of this direction. In order to obtain a high-quality target product, the possibility of using an electric-discharge effect on raw materials with a certain number of pulses to inactivate anti-nutritional compounds is presented, which prevents the assimilation of vegetable protein in the human body.

Abstract
The urgency of the problem of biodiversity conservation has grown significantly at present. In addition to the increasing anthropogenic impact on natural ecosystems, there is also a threat of changes in biocenoses due to the spread of invasive plant and animal species. The human factor also plays a significant role in this process. For example, the species Heracleum sosnowskyi Manden was used as an agricultural crop in the last century. Unfortunately, the specific properties of the plant made people refuse to use it as such. All varieties obtained by breeders were excluded from the State Register. However, the plasticity and biological aggressiveness of the species allowed it to successfully occupy an ecological niche in various biogeocenoses. Since the plant poses a real danger to human health, an intensive search is underway for ways to combat this poisonous invasive weed. The authors have developed a unique method of controlling plants Heracleum sosnowskyi M., effective and safe for humans and the environment.
