Subject: Utilization of Construction and Demolition Waste in Self Compacting Concrete
Keywords: Recycled coarse aggregate, Water absorption, Construction and demolition waste, Old mortar, Self compacting concrete, Sulphate attack
Abstract: Recycled coarse aggregate and natural coarse aggregate are two different aggregate, one of aggregate consist of old mortar over it and that is recycled aggregate whereas natural aggregates are fresh. This paper presents results of an experimental investigation using construction and demolition waste, that is recycled coarse aggregate (RCA). The RCA was obtained from IL and FS Environmental Infrastructure and services Ltd., New Delhi. Due to the large construction activity, it requires to find the suitable material to replace natural material for manufacturing concrete. In this investigation influence of different quantity of RCA on self compacting concrete (SCC) in fresh and hardened state was undertaken. The properties obtained from SCC using RCA were compared with SCC having 100% natural coarse aggregate (NCA), that is control concrete. The NCA was replaced with RCA by a quantity of 20%, 40%, 60%, 80% and 100%. The fresh characteristic of SCC was investigated using slump flow test, V-funnel test and L-box test. The hardened properties obtained were compressive strength tests after 7, 28, 56 and 90 days of curing and tensile strength after 28 days of curing. It was observed from the result that fresh properties of concrete made with RCA changes slightly upto 40% and considerable changes was noticed above 40% as compared to concrete made with natural coarse aggregate due to high water absorption. In the hardened state results of different strength properties, show that upto 60% replacement level there is slight decrease in strength but above 60% it increases. Main disadvantage noticed from the research work was as increasing the percentage of RCA, water absorption also increases. Durability of SCC using RCA was observed by keeping the sample for water absorption test, alkalinity test and sulphate attack. The water absorption increases with increasing the RCA content.

Abstract: The characteristics of water, air and soil having physical, chemical and biological changes are undesired changes. So, people around the world are under tremendous threat. Water is highly polluted day by day with different harmful contaminants. This is happening due to man-made activities, like increased human population, use of large amount of fertilizers and industrialization. natural water is contaminated due to leaching of soils, industrial processing, residential waste, municipal waste and weathering of rocks. Various water borne diseases occur in human beings due to use of contaminated drinking water. So, it is necessary that at regular time intervals the quality of drinking water should be checked. The availability of good water quality improves quality of life while prevent disease. So, for testing water quality different physico-chemical parameters were used for the calculation of water quality index.

Subject: Status of Wetlands in Delhi: A Spatial-Temporal Study
Keywords: Wetlands, Recreation, Groundwater recharge, Carbon sequestration, Encroachment
Abstract: Wetlands hold an important part of our environment. Wetlands are submerged or water saturated lands. They are productive life supporting systems, which is of vast socio-economic and ecological importance to human beings, acting as a source of irrigation, recharging groundwater, minimizing flood effects to acting as carbon sequestration. Moreover, wetlands also hold an important part in Indian culture as it is associated with many rituals. However, now wetlands are shrinking, most of them are being encroached on and transformed into other land cover classes. Delhi is also facing a similar situation. Thus, an effort has been made in this paper to study the present status and temporal change in wetland situation in Delhi, India. The presently available wetlands have been demarcated using GIS. While temporal change in wetlands in Delhi has been monitored over a period of 19 years (2000-2019) using satellite images. For that remote sensing and digital image processing techniques including various band rationing were applied. The results have also been validated using accuracy assessment.

Subject: A Residue free green synergistic biopesticide Piper betle extract to supersede pesticide thiram
Keywords: Thiram, Seed protectant, Fungicide, biopesticide, Piper betle
Abstract: Thiram (tetramethyldithiocarbamate) is used as fungicide and seed protectant in agriculture. It belongs to dithiocarbamate fungicides. The harmful effects of thiram include liver enlargement and dysfunction, degenerative changes, hepatitis and necrosis. Hence an alternative biopesticide to supersede thiram is essential. The Piper betle extract proves to be most economic, cost-effective and leaves no residue. It is easily biodegradable and available. Extract of betel leaves is very effective against pathogenic bacteria. The active component present in this extract is sterol which helps in the rupture of membrane structure of pathogens. The fungal infection occurs due to the hydrophobhicity of the cell surface which contains non-polar amino acids. The leaf extract reduces the hydrophobhicity and results in less adhesion of fungus. In the present study, the sample was subjected to evaluate biological activity of solvent extracts against fungal species, such as Fusarium sp. and Penicillium notatum. The high inhibition for Penicillium notatum and Fusarium solani in ethyl acetate extract proves that it can be used as effective fungicide against these fungi instead of thiram.

Subject: Groundwater Potential Investigation using Vertical Electrical Sounding around Injibara Town for the Supply of Awi University, Injibara, Northwestern Ethiopia
Keywords: Groundwater, Groundwater exploration, Geophysical method, Vertical electrical sounding, Aquifer
Abstract: The study area is located in Injibara town in Amhara regional state. The objective of this study was to investigate groundwater potential zones of the area for the supply of Awi University using geophysical methods particularly, vertical electrical sounding. The groundwater potential investigation considered different options based on information interpreted from geological, hydrogeological and geophysical observations as well as previous reports done in the area and data from existing wells in the study area. Hydrogeological site delineation was carried out and then followed by geophysical investigation. Schlumberger array type of electrode configuration was used to delineate the saturation zones. Tarmaber Gussa formation, quaternary vesicular basalt, covers the depth of the aquifer in selected sites. Weathering, fracturing, vesicles, intergranular pore space and contacts between different lithologic units and lineaments are the major conduits and storage of groundwater in the area. The vertical electrical sounding field data were fed to computer programmer IPI2W software. The software plots graphs and gives different resistivity layers with their thickness. Finally, the data was interpreted. Based on the hydrogeological and geophysical investigations, spring source has been proposed as first priority with corresponding groundwater source as second option for Awi University.

Keywords: Hydraulic modelling, Block ramps, Sediment transport, energy dissipation, Scour depth, friction factor
Abstract: Block ramps uniquely serve as an essential paradigm in riverine management, to encounter deliveries in an ecologically sound manner. It permits safe fish passage, stabilizes stream banks and bed profiles and creates habitat diversity. Model studies of flows over block ramps are quite extensive and are associated with many intricacies. In this paper, experiments were conducted at two flumes with three different model configurations in the hydraulic laboratory of National Institute of Technology, Patna. A comparison of the performance of three different model configurations of flows on the block ramps placed in channels with horizontal beds was studied. Experimental data analysis allowed describing the erosion mechanism occurring in the stilling basin, energy dissipation and friction factor in the interstitial flow over rock ramps. The results of physical testing can be used to assess and predict scour development downstream of block ramps, effective dissipation of energy and its impact on the stability of rock structures.

Keywords: Airport, Aircraft, Noise equivalent levels, Noise measurement, Noise pollution, Noise threshold
Abstract: This study aims to monitor and assess noise levels in and surrounding environment as a result of the operation of Bengaluru’s Kempegowda International Airport and suggest effective mitigation techniques. The level of noise at the location of retrieved results was measured and recorded during the day and night using automated noise monitoring stations located in Saddahalli, Channahalli, Mallenahalli and Reddihalli villages. It signifies that all of the areas occur in excess of a threshold noise level, which is 55 dB(A) for residential zones and 75 dB(A) for airports, according to noise standards. From the study it is observed that over 15,000 aircraft are operating every month and 430 aircraft moving on average in a day. The noise levels of aircraft movements are under the range of 70-75 dB(A) most of the time and some events exceed threshold limit at an average for the month of January. noise recorded at Saddahalli was 66.7 dB(A); Channahalli village was 63.5 dB(A); Mallenahalli village was 64.1 dB(A) and Reddihalli village was 69.8 dB(A). The maximum noise recorded was 69.8 dB(A), which is slightly harmful to human ears and causing disturbances in and around airport (KIA). Airport authority has taken action on avoiding noise pollution due to aircraft movements using latest aircraft technologies and also planning of infrastructure development which results in lesser noise pollution.

Subject: Investigation of Different Types of Human Damage on Vegetation and its Environmental Health Hazards in the Desert Areas of Central Iran
Keywords: Human damage, Vegetation, Environmental impact, Desert, Desertification, Iran
Abstract: In desert areas, vegetation plays a central role in protecting the soil and preventing dust and various diseases. Considering the importance of vegetation in environmental protection, human health and prevention of spread of different ocular and respiratory diseases, this study was conducted in Aran va Bidgol County during the 2019–2021 period. In this descriptive study, field surveys were made in spring and autumn seasons from 2019 to 2021 to analyze different types of human damage to vegetation and its environmental health hazards in the studied region. Data analysis was then performed. From southeast to northwest of Aran va Bidgol, different types of human impact on vegetation can be observed: drilling wells, changing landuse to homes and villas, changing vegetation to farms, grazing livestock, establishing tourism centers, smuggling wood, creating landfills and disposing of construction debris. Vegetation has been severely damaged in the studied region. In the absence of vegetation, dust can cause different problems in the eye, nose, pharynx and throat and can intensify the spread of respiratory diseases. People with respiratory and heart diseases are more vulnerable. Therefore, legislators and environmentalists should prohibit any manipulation of the environment in a bid to have healthier environment and prevent the emergence of environmental diseases.

Subject: An Empirical Evaluation of the Relationship Between Economic Growth, Population and Solid Waste Generation in India
Keywords: Municipal solid waste generation, Economic growth, Population, Sustainable development, Panel regression, Environmental kuznets curve
Abstract: Municipal solid waste (MSW) poses a hazard to the environment, human health and well-being and economic growth, if not managed correctly. It is essential to study the determinants of municipal solid waste generation for efficient waste management planning and achieving sustainable growth. The main objective of this paper is to establish a relationship between economic growth, population and MSW generation. Secondly, it aims to verify whether the environmental kuznets curve (EKC) hypothesis is valid in the Indian context with MSW generation as the proxy variable for environmental degradation. Panel regression has been run using statewise data of MSW generation, state net domestic product (SNDP) per capita and population for the years 2000-2019. The results show a significant positive relationship between the selected variables. Least square regression was applied to verify the validity of the environmental Kuznets curve (EKC) hypothesis in India using nationwide data for MSW generation and GDP per capita for the years mentioned above. The results depicted inverted U-shaped curve with MSW as the dependent variable and GDP per capita as the independent variable and confirmed the validity of the EKC hypothesis.

Keywords: Noise level, Earplugs, Occupational hearing loss, Sensorineural hearing loss, Hearing protection device
Abstract: Equipment involved in the laundering process may emit high levels of noise that can result in hearing loss among hospital laundry workers. The present study aim to monitor changes in laundry noise levels and worker hearing threshold levels over a four-year period. Current noise levels and hearing thresholds were compared with previous noise measurements (2015) and annual audiometric data (2017 and 2018). Audiological evaluation, including immittance and extended high frequency distortion product otoacoustic emission recording, was performed with 31 laundry workers. The laundry noise level (LAeq) ranged from 74.2-81.1 dBA. Acoustic spectrum analysis showed predominant energy levels from low to mid octave band frequencies. Over the years, the average noise level was reduced by 3.6 dBA, which can be attributed to effective maintenance, frequent servicing and replacement of worn-out machines. Audiogram results reveal bilateral/unilateral moderate to moderately severe hearing loss in 6 workers. Extended high frequency DPOAEs were absent in 32 ears at all frequencies and were present in 10 ears only at low frequencies. In order to curb the progression of hearing loss, periodic monitoring of hearing status and training/counselling to wear ear protective devices are advisable irrespective of the ambient noise levels for hospital laundry workers.

Subject: Medical Waste in Bangladesh, its Causes and Impacts on Environment and Human Health: An Overview
Keywords: Bangladesh, Dhaka city, Human health, Impacts, Medical waste
Abstract: Medical waste is infectious, hazardous and it causes deaths as well as poses serious threats to the environment. So, medical waste needs to be treated properly before its final disposal. But, due to the absence of a proper healthcare system in Bangladesh, numerous hospitals, clinics and diagnostic centers have sprung up elsewhere in from Dhaka city and produce a huge amount of waste daily. Medical waste from those hospitals, clinics and diagnostic centers is dumped elsewhere without proper treatment, thanks to mismanagement and lack of discipline, causing a serious threat to the health and environment. There is no supervision and guidance for proper treatment of the waste, there have not enough data or research work on the very critical issue in Bangladesh. The authorities concerned are yet to take any measures in this regard despite such an alarming situation. Moreover, the existing environmental laws of Bangladesh are not enough to address the issue of not having specific provisions in the laws. Besides implementation of those legal frameworks is largely absent in the country. This paper will analyze the related policies and find out the gaps and will come up with some recommendations to bring an end to the mismanagement of medical waste generation through policy and law.

Keywords: Graphene oxide, Reduced graphene oxide, Nyctanthes arbor-tristis, Hydrothermal, Sol gel, Photoluminescence, Photocatalyst
Abstract: The present study explored two energy efficient simple methods for the effective application of the anti-oxidant property of the leaf extract of Nyctanthes arbor-tristis, a highly potent reduction of graphene oxide. The samples obtained from the green method were characterized in terms of structure, surface morphology and elemental composition. The data from the analytical tools of FTIR, FT-Raman, powder X-ray diffraction (PXRD), field emission scanning electron microscopy and energy dispersive x-ray spectroscopy (FE-SEM with EDAX) and ultraviolet diffuse reflectance spectroscopy (UV-DRS) studied the structure and property relationship and indicated the enhanced smooth layer structure of the synthesized samples. There was a drastic change in the surface morphology and more reduction in the oxygen functionality (C-O, C=O, O-H) of the synthesized sample of reduced graphene oxide (rGO). These results were indicative of their suitability for tunable fluorescence and catalytic activity. Hence the samples were screened for their efficiency in the degradation of organic dyes and chlorophenols. The results were satisfactory under the given experimental conditions. The results of the catalytic study ultimately provided a unique approach to the fabrication of catalyst for industrial wastewater treatment. The tunable luminescence study of assynthesized rGO can be further investigated for bioimaging of healthy and cancer cells in cell diagnosis and biomedical applications.

Subject: Application of Fabricated Sequencing Batch Reactor and Biofilm Sequencing Batch Reactor to Treat Dairy Wastewater
Keywords: Sequencing batch reactor, Biofilm sequencing batch reactor, Dairy industry wastewater, biosludge, Biofilm carrier
Abstract: The dairy industry is observed as one of the furthermost polluting industries. While processing 1 L of milk, 2-10 L of wastewater is generated. In India, around 286 large and small-scale dairy industries generate plenty amount of wastewater. The cyclic operation of fabricated sequencing batch reactor (SBR) curtails various parameters, such as BOD, COD and turbidity and were found to be 85.78%, 76.77% and 83.21%, respectively at 10 hr. As the detention time increases, BOD, COD and turbidity reduces. The fabricated sequencing batch reactor was modified by adding plastic media at the bottom of the reactor tank as a biofilm having a surface area of 2.7 m2. The main purpose of biofilm is to enhance the efficacy and bio-sludge superiority by increasing the bio-sludge in the process. The efficacies of removal of parameters were enhanced by using the biofilm sequencing batch reactor (BSBR) reactor under the high organic loading of 1340 g BOD5/m3 day. The COD removal of 89.3%, BOD5 removal of 83%, total Kjeldahl nitrogen (TKN) removal of 59.4% and oil and grease removal of around 82.4% was observed. Under the same high organic loading, curtailment of parameters was less in conventional sequencing batch reactor (SBR) [removal of COD- 87.0%, BOD5– 79.9%, TKN- 48.7% and oil and grease- 79.3%].

Subject: An Empirical Analysis of Machine Learning Models for Developing a Custom Air Quality Forecaster
Keywords: Air quality forecasting, Atmospheric pollution forecast, Delhi air pollution, Machine learning, Deep learning, LSTM model
Abstract: The growing events of air pollution over the last decade have made implementing preventative measures a need more than a caution. An effective air quality forecasting system is the backbone of all measures. A detailed global literature review identifies statistical and ensemble models to be more efficient for forecasting problems. This study aims at experimentally analyzing 10 machine learning models on predicting PM2.5, PM10, SO2, CO, NO2 and O3 for developing a custom air quality forecaster for Delhi, India. The performance of all models was compared individually for each pollutant prediction using evaluation metrics, such as RMSE, MAE and MedAE. Based on experimental evidence, we conclude that a timeseries based deep neural network model performs best in the given scenario and can be explored further to create a custom air quality forecasting framework.

Subject: Construction of a medium for Pseudomonas fluorescens from Local Resource and its Trial Application as a Biopreservative
Keywords: Pseudomonas fluorescens, Agricultural wastes, biopreservative, Fruits, Vegetables, environment
Abstract: Pseudomonas fluorescens is a widely dispersed plant growth promoting rhizobacteria. It is not a human or plant pathogen and is found in soil, water, plants and other moist environments. This organism has already been used as a biocide against various fungi and bacteria in agricultural fields [1]. It has lots of biocontrol properties, like antibiotics, enzymes and siderophore productions. Due to its siderophore production its pyoverdine pigment fluoresces under UV light. This study was conducted mainly to construct a media with the cheapest local resource or agricultural waste and also to find its application as a biopreservative. The raw materials required for the construction of medium were agricultural wastes, such as rice husk, rice straw, wheat husk, peanut waste, dried cow dung and then coconut water, whey water and vermicompost. Then these four combinations were inoculated from the mother inoculum and their growth was checked by serial dilution and spread plate technique. Then these cultures were applied to apples, tomatoes, curry leaves and betel leaves by dip inoculation method. The keeping qualities of these vegetables were checked till the control items were rotten under laboratory conditions approximately for about 7 days. The physiological characteristics were good and fresh in the preserved items for 7 days but decayed on the control products. Thus, the first step towards the application of P. fluorescens as a biopreservative was successful.
