Authors: Rani Chilaka Vidya , Kumar Parvesh
Published: March 2021

The main aim of the present research is to enhance the thermal properties of fluids with a dispersion of various types of hybrid/nanoparticles which has the capability of improving heat transfer properties. Thermal conductivities of Nanofluids are probably higher as compared with conventional fluids. The use of metal nanoparticles has not been intensely investigated for heat transfer applications due to a lack of stability. Research hard work has been equally put forth to improve the active performance of heat transfer fluid (HTF) through the use of hybrid nanomaterial. The particularly higher surface-to-volume ratio of nanomaterial makes them properly promote nucleation and heat switch in PCM. The right choice and training of nanomaterials pave the manner for achieving superior thermal conductivity, specific heat, and heat transfer ordinary performance of hybrid nanofluids. Nanomaterials, organized in splendid systems collectively with nanotubes, nanorods, nanoparticles, etc. would possibly display off awesome thermo-bodily factors while dispersed in heat transfer fluid (water). Therefore, various hybrid/nanoparticles have synthesized the usage of the sol-gel approach. Synthesized Nanomaterials are to be tested for XRD, SEM to recognize the crystalline structure, length, form, etc. The ultrasonic process needs to be performed during the dispersion of nanoparticles in HTF for uniform dispersion and to avoid agglomeration. Then nano-based fluids are characterized to study Physical, thermal properties. The nanofluids are tested using Fourier Transformer Infrared Spectrometry (FTIR) to check chemical compatibility between HTF and nanoparticles, later a thermal conductivity analyzer is used to verify thermal conductivity of various hybrid/nano-based fluids. A thermogravimetric analyzer (TGA) is used to check the commencement and end of decomposition temperature of various hybrid/nano-based fluids. Later several experimentations are carried out using shell and tube type heat exchanger to study heat transfer characteristics of various hybrid/nanofluids. The results from various characterization techniques and experimentation are analyzed for optimizing the nanoparticles type and proportions used in HTF for proposing in practical applications.

Published: March 2021

In view of the immense use of LiNbO3 (LN) in the Photonic industry, a need arises to develop a theory to study the variation of Refractive Indices near the surface of LN device. The “Local” fields as experienced by ions on or near the surface of a dielectric medium ought to be different from those in the interior, thus one expects a Refractive Index variation near the surface of the material. In the studies involving thin films and optical waveguides, this variation could possibly alter the propagation characteristics. The variation of ordinary and extraordinary refractive indices (no, ne) from the surface to the interior of depth 69.315A° near the surface for X-cut and Z-cut LN waveguides are evaluated using theoretical Point Dipole Approximation (PDA) method. For an X-cut waveguide, no
is found to decrease from 2.9696 on the surface to 2.2864 in the interior whereas, ne
is found to increase from 1.4849 to 2.2024. The birefringence (dn=ne–no) is negative and observed to be increase from -1.4847 to -0.0840. For a Z-cut waveguide, no
is found to increase from 1.8046 to 2.2864 whereas ne
is found to decrease from 2.7005 to 2.2024. Here the birefringence is positive, decreasing from 0.8958 to zero to a depth of 60.5A° and further decreasing to -0.0840 to a depth of 69.315A°. It is observed that the variation of refractive indices no
, ne
and dn variation with depth near the surface for both the cases are quite opposite in nature. This is primarily due to the dipole orientation and their relative distributions in the lattice being different for the two directions of the electric vectors of light as is evident from the values.

The increase in usage of the automobiles day by day releases a huge amount of exhaust emissions such as HC, CO, CO2 and NOx etc. All these pollutants in exhaust emissions mainly depend on combustion phenomena which occur in engine cylinder. The effect of incomplete combustion releases a large amount of exhaust emissions as well as low brake thermal efficiency. To address these problems a noval method of magnetic fuel ionization method is adopted to condition the fuel. In the present investigation the experiments were conducted by using permanent Neodymium N52 magnet with field intensity 12,000 Gauss (1.2 Tesla) of Mono pole and Dipole that are fixed on fuel intake manifold before the fuel injector. This magnet creates a powerful magnetic field thereby the hydrocarbons changes their orientation. Due to this the molecules interlocked with the oxygen during combustion process and produces better combustion in the engine cylinder. The enhanced combustion causes to increase in the Combustion and reduction in poisonous gases from the engine.

Published: March 2021

We demonstrate that the modulated surface photovoltage spectroscopy (modulated SPS) technique can be applied to investigate interface states in the bandgap, i.e. interface passivation, of crystalline silicon coated with a downshift layer such as hydrogenated aluminum nitride with embedded terbium ions by suppressing straylight with a cut-off filter. Different hydrogen contents influence the surface photovoltage spectra at photon energies below the bandgap of crystalline silicon. Modulated SPS reveals that at higher hydrogen content there is a lower signal and, thus, a lower density of surface defect states. Our experiments show that modulated SPS can become a powerful tool for characterizing defect states at interfaces which cannot be easily studied by other methods.

In the competition of the lighting market, LED technology has stood out for excellent characteristics, one of which is the possibility of dimming, compared to other technologies. The dimming capacity allows to find the comfort zone with respect to two parameters, illuminance and correlated colour temperature (CCT). The present work provides a methodology to find comfort with respect to two variables, the level of illumination and the CCT. A controller with a simple structure, supported by Arduino, is proposed to control the above-mentioned variables of LEDs. The LEDs are located on a tape attached to a heat sink. In addition, the use of a light box as an environment for analysis is proposed. The design of this cubicle is based on literature. The controller has the possibility to regulate 12 different channels and the linearity between the PWM output and the illuminance was verified. The cubicle has an area for the observer whose dimensions are 60 cm × 60 cm. In this area, the illuminance measurement was carried out over time and the almost null variation of the illuminance 347± 1 lx was confirmed while the CCT varied in a controlled way from 3000 K to 6500 K.

White oyster mushroom (Pleurotus florida) is widely consumed by Indonesian people in daily life. It contains high nutrients, especially its protein content. Protein can be generated from meat but it is expensive and gives an economic burden to some people, particularly in this pandemic condition. The aim of this research was to improve the productivity of white oyster mushrooms using sludge biogas as biofertilizer and to provide alternative protein sources. The mushroom medium used in this research consisted of M1, M2, and M3, and each medium was made in three replications. Parameters observed were harvesting age, fresh weight, number of caps, stalk length, and diameter of caps. The data were analyzed using one-way ANOVA and the difference between means was determined by DMRT. All media with the sludge addition improved the growth and production of the mushroom. M2 medium demonstrated the best improvement in productivity. The increasing productivity in the M2 medium included fresh weight (118%), diameter of cap (22%), number of caps per cluster (225%), and stalk length (50%). In conclusion, the sludge biogas could be able to enhance the productivity of white oyster mushroom. The increasing production of this mushroom will affect the availability of alternative protein sources and support food safety in this pandemic situation.

Published: March 2021

The world’s important food commodity is rice. This rice needs to be extended annually, but the production has not been able to meet the demands. The morphological parameters’ improvement is the major aim of this breeding program. Morphological fingerprint is a unique pattern of traits which consists of a genotype for identification purposes and to detect genetic diversity as the basis of rice breeding. One of the obstacles which is faced in rice cultivation is that it has poor aeration which is caused by floods. Climate change affects the potential flooding in productive fields. The land optimization under the flooding needs to be supported by tolerant genotypes rice that are able to adapt and produced high yield. The importance of morphological fingerprint through evaluations of seventeen rice genotypes in a potentially flooded environment, would increase the efficiency of the breeding programs. The study of variability on yield and these components of rice genotypes showed a wide range of variation and specificity for all traits. The Pearson correlation coefficients for fifteen characters indicated that rice yield had a positive and significant correlation with culm diameter, biomass, and harvest time. The performance of rice genotypes had a significant negative correlation on 1000-grain weight and biomass.

Authors: Dewi R R , Kustantinah  , Muhlisin
Published: March 2021

Sheep is one of the small ruminant producing red meat in Indonesia. Sheep meat contains higher saturated fatty acid compared to non-ruminant meat products. Meat consumption with high saturated fatty acid should be limited due to a higher risk of atherosclerosis (blood vein constriction) causing coronary heart disease. Strategy to reduce saturated fatty acid in the sheep meat should be conducted by increasing unsaturated fatty acid content in sheep meat. Accelerating unsaturated fatty acids can be done by feed supplementation containing unsaturated fatty acid. It can be done by protecting unsaturated fatty acids to avoid bio-hydrogenation process in the rumen. Lemuru fish oil can be utilized as an unsaturated fatty acid source. Supplementation of protected lemuru fish oil in total mixed ration (TMR) is considered to improve treatment effectivity, due to sheep is unable to choose certain feedstuffs and instead of ingesting the whole diets so that the consumed diet had balance nutrient. Supplementation of protected fat is suggested to not modify rumen fermentation, improving sheep performance, and increasing unsaturated fatty acid content of sheep meat. This review provides previous research studies with protected fat supplementation in sheep diet.

Methodology for identifying homogeneous consumer groups based on qualitative data
Authors: Gabidinova G S
Published: March 2021

In this article, the author proposes a method for identifying homogeneous consumer groups based on qualitative data. The problem is that when researching the end-user market, information is often presented not in quantitative but in qualitative form. The random variables with which mathematical statistics deal are usually assumed to be numeric. Therefore, among researchers there is an opinion that achieving at least an interval level of measurement is always desirable, since it expands the researcher capabilities, giving him grounds to use data mathematical and statistical analysis traditional methods. Sociologists, on the other hand, emphasize the qualitative data enormous role in the respondents’ study. The presented methodology is based on cluster analysis, differs from the applied market segmentation methods in that it uses cluster analysis algorithms developed concerning qualitative indicators, and involves a proximity measure use that allows one to determine the natural weights between clustering variables. Also, the technique provides for the optimal partition determination based on the changes’ graph in the average internal communication, depending on the selected clusters’ number. The optimal among the partitions set is considered to be a partition in which the average internal connection increases sharply in comparison with the previous partition. Provided that the clusters’ number in each subsequent partition in comparison with the previous one is greater by one. Thus, the methodology allows identifying the existing market structure.

Published: March 2021

At present in the conditions of economic sanctions, the problem of providing the population of the country and regions with food supply and light industry products at affordable prices and high quality comes to the fore. Agriculture is the most important link of the national economic complex and differs from other branches of the economy in the seasonal nature of production, the use of land as an object and means of labor and a strong dependence on natural conditions. Agriculture shows not only a steady implementation of all indicators, but even growth in some areas. Thanks to this, it was possible to maintain the stability of consumer prices for the main types of products. Features of agriculture in Siberia are caused by harsh climatic conditions, but despite this, this branch of the national economy is developing at a high rate and plays an important role in the life of the region.

The state policy in the field of environmental management is part of environmental policy. One of the national priorities designated by the Russian government is the rational and competent use of natural resources, i.e. improving the system for monitoring the quality of air, soil and water, as well as the formation of a high environmental culture in society. One of the most important socio-economic tasks, as we see, is to study the state of the natural environment, predict changes in its conditions, both in natural conditions and under the influence of anthropogenic factors, in order to predict possible risks. The study of the problem of assessing the state of the environment in combination with the use of information technologies is very promising, including when analyzing the impact of toxicants on the environment

The modern history of organic farming in Russia began in 1989 with the implementation of the state program “Alternative Agriculture”. Organic agriculture in Russia was initially considered as a condition and mechanism for the development of small and medium agricultural forms of production. The increase in the production of agricultural products and food in excess of the normative requirements, ensuring the country’s food security led to the expansion of exports. Russia’s aptitude to uphold fulfillment with global standards and be competitive in world markets where ecologically clean agricultural products are in demand is quite high: huge reserves of land in Russia, the introduction of ecological farming systems must be carried out on huge areas, coordinated with a large number of small owners. Information support for farmers about new, more efficient technical means, biotechnologies in organic agriculture and certification of organic products for environmental friend-liness, safety of manufactured products, the use of intensive biotechnologies, financial support of organic agriculture, processing and sale of organic products remain problematic.

The use of whey in the manufacture of food products is among the important areas of using milk as a raw material. Milk whey has a fairly high biological and nutritional value. It contains about 50% of all nutrients that are in milk. When manufacturing any product, it is necessary to take into account all possible hazards that can change the characteristics of the product and, subsequently, harm a person. HACCP is the implementation of a regular approach to ensuring the safety of manufactured products. The purpose of our research is to determine the critical control points of the production process “Frozen whipped fruit and berry dessert from whey”. As a result of the research, it was revealed that in the technological process of the production of whipped frozen fruit and berry dessert from whey, there are four critical control points: KKT1 - pasteurization, KKT2 - cooling and temporary storage, KKT3 - adding fruit and berry filler, citric acid, KKT4 - packaging, hardening, packaging.
Financial and credit instruments of activation of environmental entrepreneurship in the agrarian sphere
Authors: Zhigir A A
Published: March 2021

Financial and environmental problems in agriculture are a consequence of prevalence of extensive development aspects of agricultural sector, absence of a productive policy of greening the country’s agriculture. The article discusses the problems of finding sources of financing for environmental entrepreneurship in the agricultural sector, since one of the main reasons of environmental degradation and non-compliance with the principles of environmentally friendly nature management in the country and its regions is low level of financial support for environmental costs. The importance of improving the strategy of ecological and financial development of the enterprise is revealed. Taking into account, the limited financial resources of entrepreneurial formations in the agricultural sector and the imperfection of the mechanism for their accumulation, the way out of the situation is seen in the diversification of sources of financing the agricultural sector, through the development and combination of state financial support, commercial and cooperative financial support.
Methodological indicators of economic security of poultry enterprises
Authors: Roiter L M
Published: March 2021

The article deals with the actual problem of ensuring the economic security of poultry enterprises. The current state of development of economic entities in the industry is characterized from the standpoint of violation of their financial potential. It has been proved that the growth of quantitative indicators of the volume of poultry products produced is not a criterion for the economic security of industry enterprises. The dynamics of absolute and relative financial indicators on average in the industry indicates a lack of resources for the implementation of the entire production process. In this regard, an assessment of the economic security of poultry enterprises is given using traditional indicators of such analytics and modern models that optimize the balance structure. The analysis of the economic security of a particular poultry enterprise is carried out according to certain methods and the conclusion is given that the values of the criteria characterizing the financial position, business activity, as well as the return and capacity of the property are lower than their standard values. Consequently, the statement of the fact of assessing the economic security of an economic entity in the industry is not enough. The development of appropriate management decisions based on an optimization model of the transition from an unsatisfactory balance sheet structure to a satisfactory one is required. Этa пошaговaя пpоцедуpa былa пpоведенa c выходом нa бaлaнc c положительной cтpуктуpой. This step-by-step procedure was carried out with an exit to a balance sheet with a positive structure. Thus, the present methodological basis for assessing the economic security of any business entity requires an integrated approach to solving this issue.

Published: March 2021

The article presents the results of determining the indicators of milk productivity of dairy cows in the Volgograd region. The studies processed the data of monthly control milking of five large agricultural enterprises of the region (LLC JV “Donskoe” Kalachevsky district, PZK “Put Lenina” Surovikinsky district, “Vostok” Nikolaevsky district, “PZK named after Lenin” Surovikinsky district, FSUE “Irrigated” Sovetsky district ). A comparative characteristic of the milk yield of the presented breeds of cattle in different periods of the year is given. Physicochemical definitions of milk quality indicators were carried out according to generally accepted methods - fat content (GOST R ISO 2446-2011) and protein (GOST 23327-98). A comparative analysis of the fat and protein content in the milk of dairy cows by periods of the year is presented. To analyze the chemical composition of milk samples by inductively coupled plasma mass spectrometry (ICP-MS), a Nexion 300D quadrupole mass spectrometer (Perkin Elmer, USA) was used. The determination of the chemical composition of milk samples by inductively coupled plasma atomic emission spectrometry (ICP AES) was carried out using an Ortima 2000DV atomic emission spectrometer (Perkin Elmer, USA). The results obtained showed the content of chemical elements in the milk of cows in the summer period within the limits of permissible concentrations, including the content of heavy metals (cadmium, mercury, lead, arsenic). Studies carried out with milk samples obtained from animals from all experimental farms have shown that the controlled indicators of milk quality, the content of chemical elements correspond to regulatory documents and raw milk of all farms is recommended for use in the production of all types of fermented milk and dairy products.
Comparative analysis of reviews of the Russian Agricultural Bank
Authors: Kuznetsov P A , Plotnikov A V
Published: March 2021

The paper analyzes reviews of the Russian agricultural Bank (the study’s object, one of the largest banks in the Russian Federation, specializing in financing enterprises in the agro-industrial complex). We used the Mann-Whitney U statistical test, The Wilcoxon signed-rank T test nonparametric statistical test, and the Pearson correlation coefficient to compare subsamples. In the study results, we determined that reviews with a higher rating are less understandable and straightforward and contain more complex texts. Conversely, reviews with lower ratings are more specific and easier to understand. Thus, we can reject the null hypothesis that the subgroups of reviews rated “5” and “from 1 to 4” are quantitatively the same.
