Published: December 2020

Abstract
The rapid urbanization in the fast growing cities is posing a major problem for the planning authorities. Most of this urbanization is experienced in the peri-urban areas which refer to the settlements beyond, about or around cities. They are characterized by the changing economic and employment structure along with rapid population growth, changing spatial development patterns, unregulated growth, haphazard developments, low quality housing and inadequate infrastructure facilities. Proper site suitability assessment involving detailed investigation of the land parcels with respect to the available resources required for the urban settlements which will lead to sustainable growth of the peri-urban area is required. In the current research study, site suitability assessment has been carried out for Neelambur, one of the peri-urban areas of Coimbatore city. The factors considered for identifying the land parcels suitable for urban settlement included the land-use of the study area, proximity of sites to the nearest road, proximity of sites to the nearest facilities of importance and slope of the study area. The Analytical Hierarchy Process based Weighted Overlay Method was used in Geographic Information System to identify the land parcels suitable for urban settlements in order to ensure a sustainable development in the study area.The results indicated that 5.29 sq.km of the study area was classified as highly suitable for urban settlements. The results of the current study can be used by the local planning authorities in establishing development control norms for ensuring the sustainable growth of Neelambur.

Published: December 2020

Abstract
A beam (flexural member) with several regular openings with different shapes is called a castellated beam. The castellated beams are well accepted in the industry, multi-story buildings, and power plants due to their increased depth of the section along with the web results in increased strength and stiffness. Though numerous simulation and experimental analyses have been made on the castellated beam, with intermediate transverse stiffener, bearing stiffener and torsion stiffener are used to increase a load-bearing capacity of the beam, but the study on the understanding of diagonal stiffener in the opening is very meager. The objective of the research is to investigate the linear behavior – ISMB150 and IC225 castellated beam of hexagonal openings with and without diagonal stiffeners and the effect of fillet radius at the corner of the openings is studied. Using finite element analysis software,Hyper works, with OptiStruct as a solver, under simply supported beam construction with four-point loading conditions was analyzed by developing an efficient 3D model for the analysis. Due to the openings in the section, the sharp corner of the opening is subjected to Vierendeel failure by the formation of plastic hinges at the corners, which makes critical hence by providing diagonal stiffener in the direction of diagonal tension and diagonal compression for the smooth flow of shear forces. The results show an improvement in load-bearing capacity of 1.51 times in the castellated beam than the parent section ISMB150. The stiffener provided further enhances the same to 1.45 times compared to the ISMB150 section. The linear results show lesser stress concentrations at the web opening corners, thus reducing the prominence of failure at the corners.

Abstract
With rapid growth of population in urban and rural areas, purchase of motorized vehicles is also grown and the demand for proper transportation network which can give good compatibility to the road users has become a major challenge in India. Level of Service (LOS) is one such parameter in terms of compatibility that gives a quality measure for the operational conditions within a traffic stream, i.e., generally in terms of service that is provided by the road to the user. This paper investigates on the existing level of service models for urban and rural roads given by researchers globally. To determine the Level of service of a particular road section, there are few commonly used methods like, Cluster Analysis, Genetic Algorithm, Fuzzy Set Theory and Neural Network etc., which are used, were discussed and reported in this paper. A new approach for finding level of service was introduced, i.e., using volume to capacity ratio (v/c), average speed of the vehicles, percentage speed reduction is also discussed and presented. This paper brings out the collective information on LOS and its findings using analytical models which can estimate/predict compatibility levels of various road users in heterogeneous traffic conditions in urban environment. The objective of this project is to study Los for various selected roads were obtained and discussed. Research work was carried in Bhimavaram (India) town, Ramayanpuram, Jaganadhapuram villages. Both study area-1,3 was observed to have LOS-D grade whereas study area-2,4 was observed to have LOS-E grade. Some of the remedial measures were given in order to increase its Los grades towards better satisfaction of traffic conditions.

Authors: Murthi P , Poongodi K , Gobinath R 
Published: December 2020

Abstract
Concrete is the second most consumed product next to water on earth. Cement is the key ingredient for making concrete. India is the second largest cement producer in the world. The production of cement is emitting an equal amount of CO2 in to the atmosphere and is accounted as about 8% of the world’s total emissions. The addition of mineral additives as supplementary cementitious materials in concrete is one of the solution to avoid such environmental pollution. The natural mineral admixture obtained from the novel agricultural by-product, namely corn cob ash (CCA), is being utilized in cement manufacturing and concrete construction. The similarities in both physical and chemical properties of CCA were established when compared to the decade old agro-based mineral admixtures like rice husk ash (RHA) and sugar cane bagasse ash (BA) through research findings. The results are mentioned that the CCA can be used as chemically active mineral admixture and micro-filler in concrete. With this background, the paper presents a review on the effect of substituting CCA in fresh, mechanical and durability properties of concrete.

Published: December 2020

Abstract
The most prominent building material utilized within the field of civil engineering was concrete. Among structural elements concrete have very poor scrap value, so that it cannot be used anywhere. This paper deals about the possibility of utilizing the structural waste as replacement for ingredients used in concrete. Recycled aggregate were replaced of about 20%, 30%, 40% in the coarse aggregate. In order to increase the strength of concrete, the fibres like steel fibre, polypropylene fibre and glass fibre were used. They are all added of 0.5% each from the total weight of cement. Additional admixtures like lime and silica fume were incorporated to expand the strength of the concrete. The specimens were casted to consider its mechanical properties. By comparing the consequences of various proportions the specimens having 20% of Recycled aggregate has accomplished the best compressive strength of 62.2 N/mm2. The result is of 8.86% not exactly typical mix. This proportion also shows great outcome for split tensile strength and flexural strength (i.e., 5.10 N/mm2 and 5.6N/mm2). Thus by expanding the level of reused aggregate, the strength of concrete is tends to decrease.

Published: December 2020

Abstract
In concrete, many properties influence the strength parameters, among that most important parameter is proper compaction. Complete compaction is not possible using conventional concrete with hand compaction or machine vibration in structural element like long column and beam column joints. In these cases, self-compacting concrete (SCC) plays a vital role. It gives full compaction without any external effort. This type of concrete compacts by its own weight, another important advantage with SCC is the absence of segregation. Hence SCC usage has increased enormously in the last few decades. Having lot of merits SCC also has few demerits. One important demerit is that, to prepare SCC lot of cement content is needed compare to conventional concrete; this may increase the CO2 emission also it leads to higher heat of hydration this may cause shrinkage cracks if adequate curing is not provided. This study is an attempt to review the influence of different types of mineral admixtures and chemical admixtures used in self compacting concrete along with a brief knowledge about the change in mechanical behaviour with respect to the influence of these admixtures.

Published: December 2020

Abstract
Owing to the advantages like intense compressive strength, large ductility and enormous energy incorporation, Concrete filled steel tube column system is gaining momentum when set side by side to regular steel or reinforced concrete system. Local buckling is one such major advantage that CFST gives experimental results from various articles has proven that there is an increase in the properties of CFST over normal concrete systems. This paper aims to give brief understanding on the experiments works conducted and numerical results obtained from various articles are discussed. Experimental works exposed to view that circular concrete filled steel tubes were more appropriate than square concrete filled steel tubes. In this paper, nonlinear finite element analysis for concrete filled steel tube is effectuated through varied parameters like concrete infill grade, as short columns with diameter ratio (L/D) not exceeding 4.5 with devoid of slenderness have also been discussed. The past studies divulged that the increment of D/T ratio dwindles the load carrying capacity of CFST and moreover, the high concrete infill grade buttress the load carrying capacity. From various literature reviews it was also concluded that the confinement efficacy of concrete enlarges the resistance to axial loading of compound columns with concrete filled circular sections. Furthermorefor the CFST columns the buckling failure can be evaded, as well as the load carrying capacity can be strengthened by hauling down the slenderness ratio. Therefore ample scope exists in carrying of numerical analysis using ANSYS to find the potential of CFST columns.
The effectiveness to cleanup oil spills from the water environment of the combined sorbent on the basic of PUF and chitin
Authors: Trang T Y D , Zenitova L A 
Published: December 2020

AbstractThis study provides information about evaluating the parameters (density, buoyancy, sorption capacity) of a combined oil sorbent based on polyurethane foam filled with chitin (PPU10M). In comparison with the original chitin, the developed sorbent has better buoyancy, and commensurate with the pure polyurethane foam (PUF). The effect of the contact time, the type of the water, the thickness of the oil layer and the adsorbent dosage are studied. The results show that the optimal contact time of the sorption process is 60 minutes. In which, the oil capacity of the sorbent PPU10M in artificial seawater reaches 13.6 g/g and in artificial river water 13.2 g/g. The sorbent dose depends on the thickness of the oil layer on the water surface. For a thin oil layer, the use of 1g of adsorbent reaches higher oil capacity but the oil removal percentage lower in comparison to the dose of 2g sorbent. For an oil layer thickness equal to or greater than the height of the sorbent cube, the efficiency of oil removal is observed better when using 2g of sorbents. Thus, it is considered that the use of 2g sorbents is optimal. A generalization of the research results indicates the prospects of the developed combined sorbent based on chitin and polyurethane for oil spill treatment.

Published: December 2020

Abstract
Iron-lignosulfonate complexes are used as trace element fertilizers to control plant chlorosis caused by iron deficiency. In this study, iron-lignosulfonate complexes were synthesized by anodic dissolution of iron in solutions of sodium lignosulfonates or lignosulfonic acids. The resulting solutions of the iron-lignosulfonate complex do not contain extraneous ions that are present in similar preparations synthesized chemically from salts. Electrosynthesis of iron-lignosulfonate complexes was carried out with two iron electrodes with alternating polarity, changing the period of switching the polarity of the electrode, temperature and the duration of electrolysis. The anti-chlorosis action of the synthesized iron-lignosulfonate complex was tested while growing lupine on calcareous soil. The plants were treated with solutions of the synthesized complex by the non-root method after 10 and 20 days of their cultivation. For comparison, lupine was also grown on normal soil and on calcareous soil without iron-lignosulfonate complex treatment. The content of chlorophyll, the content of carotenoids and the mass of the ground part of the plants treated with the synthesized complex were the same or higher than those of the plants grown on normal soil. In addition, all these parameters were 2-3 times higher than that of the plants grown on calcareous soil without treatment.

Abstract
During using biogas as fuel for diesel engines, it is necessary to clean it from hydrogen sulfide, water and carbon dioxide, as well as to compressing it to fill cylinders more efficiently. Today the production of biogas in agriculture is the disposal of crop waste and manure from livestock farms.This approach is very actual, at the first stage of its implementation was planned to create the necessary material and technical base to widespread using of non-traditional energy sources, including organic biomass energy (fertilizer, crop waste, etc.). In addition, environmental protection, which also requires intensive and rational processing of animal waste, is very closely connected with the problem of waste disposal. This necessitates the search for processing methods that would ensure the comprehensive utilization of its agricultural, energy, feed and other properties. This article presents the technology for processing the utilization of manure using microbial synthesis. When processing manure in anaerobic conditions, the threshold lowered for its smell, germination of weed seeds, helminths die, and nutrients (nitrogen, phosphorus, and potassium) are completely preserved. The resulting biological gas contains up to 70 % methane, and its calorific value is 24 MJ/M3. The introduction of low-waste, resource-saving technologies with mechanization and automation of production processes plays an important role in the environment protection issues from livestock complexes waste in their further development. At present, there are several directions of processing of agricultural and water waste. At the same time, processing of animal waste with the use of biogas plants gives a significant socio-economic effect, expressed in improving working conditions, increasing the production culture and land use. Moreover, the environment protection rask is being solved.

Published: December 2020

Abstract
Abctract. Interest in involving countryside territories in economic turnover occurs the various ways. Housing construction, development of agro-industrial complexes, introduction of innovative technologies, redistribution of the land Fund, etc. The main problems: lack of coordination of actions, unidirectionality of agroeconomic, working in areas of risky farming, seasonal employment. At the same time, socio-economic and infrastructure issues remain out of attention: priority and procedure for financing social facilities, strategic planning of village territories, industry interaction and total environmental impact on the territory. The lack of interaction between stakeholders allows us to solve only operational tasks. Increasing the investment attractiveness of the territory requires a comprehensive approach that provides a synergistic effect of industries. Systematic redistribution and involvement of free population flows in rural labor allows not only to satisfy the growing interest of citizens in active forms of recreation, but also to ensure the introduction of organic forms of agriculture in agricultural activities. The study of recreational motivation in combination with branding of rural areas allows us to predict not only investment activity, but also the reorientation of citizens towards environmentalization and self-employment [1].
