Published: December 2020

Abstract
Agro-climatic zonation is a classification technique that uses several meteorological and topographical data of our targeted region for proper zonation with higher priority towards crop suitability factors. This study deals with creating such zonation using 7 major factors for the entire state of Tamil Nadu using GIS and AHP. The Agro-climatic variables include precipitation, evapotranspiration, land surface temperature, land use and land cover data, soil moisture, soil order and ground water level. On incorporating the data in GIS with attribute tables, thematic maps were created through inverse distance weighting interpolation. Such maps were over-laid so that zoning using all the defined factors could be made feasible. Weightage given for each factor was determined based on Analytical Hierarchy Process, with precipitation and soil order with the highest priority. A final map was obtained with Agro-climatic zones defined based on the degree of suitability for agriculture from highest to lowest. This classification can further help to define the suitability of various crops on a region and can help in planning an appropriate crop pattern for that region.

Published: December 2020

Abstract
The behaviour of any structuredepends upon the structural element present in it. The critical aspect on which the structural configuration depends are shape, length and geometry of the building. In the present study the performance of vertical geometric irregular tall structures under the wind load is evaluated as per IS 16700: 2017 provisions. Three type of vertical geometric irregular tall reinforced concrete buildings having different plan dimensions with cantilevered offset length varying from 11% to 15% of the building lateral dimension with increment of 0.5% are modelled. Modal analysis and wind analysis are performed using structural analysis software ETABS to assess the behaviour of vertical geometric irregular tall structural system with cantilevered offset. Parameter such as time period, frequency, storey displacement and storey drift are studied and compared with the regular building. Multiple linear regression analysis is carried out to formulate a general expression for the responses of the vertical irregular tall buildings.

Abstract
Soil is defined as minerals, gases, organic matter, liquid and organisms which together supports the life. Black cotton soil being clayey, deep, and impermeable, expands and becomes sticky during rainy season and contracts during the dry season engendering deep cracks. Black cotton soil being more expansive in nature, the shear strength is very less and thereby, lowering the bearing capacity too. To overcome the problem of low strength and bearing capacity of locally available soil and to stabilize soil for a longer life of buildings, improvisations have become a necessity. In this present study an effective technique is provided for ground improvement for soil stabilization using bio enzyme. Bio-enzyme namely Terrazyme is added to improvise Unconfined Compressive Strength (UCS) and California Bearing Ratio (CBR) value of soil, and these are further compared with virgin soil’s CBR and UCS values. The laboratory tests were conducted like California Bearing Ratio Test, Atterberg Consistency Limits and Compaction test on soil samples with differential Terrazyme. Percentages for redefining the properties. From the results, it is evident that Terrazyme has proven to be a most satisfying add-on that helps in improvising the supreme characteristics of the soil with the usage up to 0.2 - 0.4 ml. Being economical and eco-friendly makes it to stand out of all and has made it more preferable than other enzymes. The study concludes, the soil has become more stable to support a greater life span and more strengthened in the presence of Terrazyme. The experimental investigations and further discussions concerning Terrazyme usage can be more precisely contemplated in the paper.

Published: December 2020

Abstract
The Construction Industry is one of the industries contributing highest GDP in Indian economy. The material that is most chosen in construction Industry is concrete. Concrete is a material made with Cement, Fine aggregate in the form of sand, Coarse aggregate in the form of gravel and water. With increasing scarcity of sand, construction works are coming to jolt and thereby increasing the need for choosing an alternative material. Vermiculite is a material which after exfoliation can be used as a filler material replacing sand partially without affecting strength much. One more material Granite (by product which is a waste is causing lot of environmental Issues), produced from granite industry, is available in India in several million tons. Coarse aggregate generally used is a crushed aggregate obtained from rocks like granite, basalt and soon. Recycled aggregate is an aggregate which is obtained after demolishing of an existing building, which is a waste causing economical in balance and which if put into use can not only decrease the construction cost but also make this waste into a better use. In the present study, for a M35 grade of concrete, Vermiculite (0, 5%, 10% and 15% of weight of sand) and granite powder (fixed at 10% of weight of sand used) is used to replace sand partially and in the place of normal coarse aggregate, recycled aggregate is used which is 20 mm passing and 12 mm retained After preparation of Mix-Design(1:1.83:2.69 with w/c ratio of 0.38) the concrete cubes are casted to test for compressive strength after curing for 28 days, 56 days and 90 days. Forsec brand super plasticizer is used to take care of workability requirements. Durability test in the form of resistance to attack of sulphuric acid was conducted along with compressive strength. The test results were promising at 10% replacement levels of Vermiculite.

Authors: Biradar Sangmesh V , Injaganeri Sidram S 
Published: December 2020

Abstract
The use of reinforcement of Fibre- Reinforced Polymer (FRP) in concrete structures has increased rapidly in the last 25 years due to its excellent corrosion resistance, fire resistance, high alkali resistance, high tensile strength to weight ratio, durability, flexural strength, insulation, good fatigue properties and magnetic transparency properties. Basalt concrete reinforcement bars called Basalt Fiber Reinforced Polymer (BFRP) are a new material, so it is important to define the mechanical properties and drawback of their use in the concrete structures in comparison to conventional reinforced concrete members.
In this study Flexural behaviour of concrete beams reinforced with basalt rebars will be tested and compared with the Flexural strength obtained from experimental result with RC Beams and ACI-440 codal provision. It has been shown that much lower cross-sectional stiffness of the BFRP basalt bars produces higher deflections and crack widths compared to the steel bars beams of the same cross-section. Comparisons between the flexural strength obtained from the ACI-440 codal provision and that experimentally values in the current investigation elsewhere indicates disagreement.
Potential of Fly Ash Polymerized Sand as an Alternative for River Sand in Concrete- A State of the Art Report
Authors: Lizia Thankam G , Neelakantan T R , Christopher Gnanaraj S 
Published: December 2020

Abstract
The depletion of the natural resources and the growing demand for the natural river sand in both developing countries and developed countries paved way for the evolution of new trends in the complete and partial replacement of the natural sand as the fine aggregate. Many natural admixtures and by-products were so far analyzed for the feasibility of the replacement of the natural sand. Some of such traditional sources suggested by the researchers were foundry sand, M-sand, quarry dust, I- sand and treated sea sand. Among which M-sand tend to meet the standards and in practice too for construction in India (Author’s native) and other countries without any ordeal. However, a new technique for the complete replacement of the fine aggregate was introduced which incorporates the polymerization technique in the byproducts (Fly Ash). Though the first introduced technique was quite tedious, the consequent authors proposed much simpler methodologies that develop fine aggregates with characteristics similar to that of the natural sand which is also lightweight, eco-friendly and economical as discussed in this article. These geopolymerized fine aggregates set a new era in the construction industry which in turn conserves the balance of the ecosystem.

Abstract
In this work, providing human body with essential food components was assessed and the physiological role of chemical elements - iron and manganese - was considered. They are among key nutrients essential for human body. Iron plays an important role in the functioning of immune system; it is necessary for the full functioning of brain and nervous system. Iron deficiency can cause iron deficiency anemia which leads to a slowdown in children’s mental and psychomotor development. Manganese has an effect on the functioning of nervous system; it participates in exchange of impulses between nerve cells and regulated reproductive function of the body. This element promotes insulin secretion and metabolism of fats and carbohydrates, it is necessary for blood formation, metabolism, functioning of musculoskeletal system, immunity, hair growth, normal skin, and is an antioxidant. Microelementoses with metabolic disorders of substances such as iron and manganese can be caused by deficiency, excess or redistribution between the reserve and functional funds of microelements under consideration. Based on this, we can summarize that iron and manganese are indispensable microelements for human body; their deficiency results in undesirable pathological metabolic disorders. Considering the relevance of this problem, the analysis of the content of chemical elements in samples of vegetable crops was carried out. These results a high iron content in beets and potatoes what indicates their nutritional value; sufficient consumption of them covers the daily requirements for manganese and iron.

Published: December 2020

Abstract
The paper considers the first stage of salt deposition, namely, the features of calcium carbonate formation in the soils (solonchak-like formations) of the Aral Sea dried bottom, its south-eastern part. The studied soils (sandy and silty-clay soils) are significantly saline and enriched with calcium carbonate. The content of only mollusk shells can reach 10-20%. The content of mineral CaCO3 in the soils is quite uniform, its content varies by no more than an order of magnitude, which indicates relatively close conditions for its formation in soils with different particle size distribution. However, the types of aggregations of calcium carbonate (with a close size ca. 250 µm) and the mechanisms of their formation in the soils are different. In sandy soils, ooids (CaCO3 cutans on the surface of sand-sized particles) are formed by the template mechanism. In silty-clay soils with a large number of crystallization centers (the predominant particle size is < 50 µm), the precipitation of calcium carbonate leads the formation of CaCO3 microaggregates from silty-clay particles. Separate crystallites and mesocrystals of calcium carbonate (up to 40 µm in size) are found singly.

Published: December 2020

Abstract
Lake Baikal is the world’s deepest lake and declared a UNESCO World Heritage Site. The most severe environmental problem facing the lake is the impact of water level regime fluctuation related to natural and human-caused factors. A core region under study is selected a territory of the Angarsky Sor – a shallow bay located in the Northeast of the lake. The research into a changing water content of the territory is based on imaginary provided by the Landsat-8 satellite. The study is focused on photographs taken in the high-water summer 2014 and in the law water level year 2015. The outcome of performed calculations is that an area of marshy and excessively wet regions has decreased more than 1.5 times, whereas there is a slight increase in the area of droughty waterless zones. Principal changes have been detected in the northern and north-eastern part of the Sor territory. Geoinformation technologies and remote sensing methods are considered to be efficient for the monitoring water level fluctuations, changes in the water surface area and vegetation mantle state of land ecosystems in the Sor region, what is essential for the preserving unique wetlands of the Angarsky Sor.

Published: December 2020

Abstract
The study investigates an anthropogenous influence on the humus content in meadow and meadow-bog soils under rice cultivation in Adygea (Gleyic Phaeozems and Calcic Chernic Gleysol). A field experiment focused on the use of mineral fertilizers N0P0K0 (control); N90P60K45; N120P80K60; N150P100K75 and N180P120K90 is carried out on rice paddies. Soil samples are taken from the plow layer before seeding and after harvesting of rice; a total humus content and fraction-group composition are studied. An increase in fulvic acids is detected in soils as a consequence of dominant reduction and oxidative degradation of humic acids. Heightened amounts of fertilizers make humus more fulvic. A labile fraction in the total humus content is determined to be 7.97-11.02 % in meadow soil and 5.38-8.33 % in meadow-bog soil. In labile humus of meadow soils fulvic acids prevail over humic acids (HA-1: FA (1a+1) = 0.71-0.89). A share of fulvuc compounds is higher in meadow-bog soils (HA-1: FA (1a+1) = 0.38-0.55). Mineral fertilizers taken in ratios of N150P100K75 and N180P120K90 raise a percentage of newly formed humus substances.

Published: December 2020

Abstract
The article analyzes the features of grain production in the Novosibirsk region of Russia. The authors analyzed the development of innovative technologies in farms. Unfortunately, extensive technology is still the most common. In the Novosibirsk region, 60% of agricultural enterprises use extensive technology and create 49% of the gross grain harvest with an average yield of 14.3 hundredweight/ha, 20% of farms create 26% of the gross grain harvest with a yield of 23.3 hundredweight/ha, 11% of farms create 21% of the gross grain harvest with a yield of 33.4 hundredweight/ha. The authors chose the Novomayskoye farm in the southern forest-steppe zone of the Novosibirsk region as a model. The simulation results were tested in practice, they showed that the transition to intensive technology with direct seeding (No-till) required an increase of 1.5 times the technical support and costs for mineral fertilizers and plant protection products, i.e. from 6 thousand rubles/ha of wheat crops to 9 thousand rubles/ha (in 2020, 1 USD≈65 Rub), but this allowed to reduce fuel consumption by 30 - 35% and the need for machine operators by 1.7 - 2 times.

Published: December 2020

Abstract
This article describes the problems encountered by grain processing industries. In this regard, we are looking for methods of intensive grain dampening, allowing to reduce the technological cycle of flour production by reducing the time of softening. The article also considers the process of secondary dampening of grain before milling by using pulsating vacuuming and subsequent pulsing pressure. An experimental unit for grain dampening before milling is presented and the basics of its operation are described. In addition, the paper provides the results of the experimental study of wheat grain dampening using pulsating vacuum and subsequent pulsating pressure, and provides control results of the experimental study of wheat grain dampening without vacuum and pressure. The results of the experimental study were analysed; according to said analysis it is evident the increase in moisture content of wheat grain in case of dampening with the use of pulsating vacuum and subsequent pulsating pressure is more intense than in case of dampening without the use of vacuum and pressure, which leads to a two-fold reduction of the softening time. The dependence between the dampening increment ΔW and the grain processing time t in the experimental dampening unit was determined. Having analysed this work, were made our conclusions that are presented in the article as well.
