Poverty-related bandwidth constraints reduce the value of consumption
Authors: Schofield Heather , Venkataramani Atheendar S. 
Published: August 2021

Significance
Poverty confers many costs on individuals, primarily through constraining material resources. Poverty may also worsen welfare by reducing the utility (or enjoyment) individuals may get from whatever little they are able to consume by constraining cognitive resources—conferring a “double tax” on the wellbeing of the poor. However, the impacts of poverty on utility from consumption are not well known. We conducted a randomized experiment in India to investigate this question. We found that participants randomized to various features of poverty (e.g., thinking about a difficult financial situation) reported reduced enjoyment on a range of subsequent activities. The findings suggest that programs that alleviate the material deprivation of poverty may be even more valuable than assumed.

Abstract
We report the results of the analyses of the cosmic ray data collected with a 4 tonne (3×1×1 m3) active mass (volume) Liquid Argon Time-Projection Chamber (TPC) operated in a dual-phase mode. We present a detailed study of the TPC's response, its main detector parameters and performance. The results are important for the understanding and further developments of the dual-phase technology, thanks to the verification of key aspects, such as the extraction of electrons from liquid to gas and their amplification through the entire one square metre readout plain, gain stability, purity and charge sharing between readout views.
Separation of scales: dynamical approximations for composite quantum systems*
Authors: Burghardt Irene , Carles Rémi , Kammerer Clotilde Fermanian , Lasorne Benjamin , Lasser Caroline 
Published: August 2021

Abstract
We consider composite quantum-dynamical systems that can be partitioned into weakly interacting subsystems, similar to system–bath type situations. Using a factorized wave function ansatz, we mathematically characterize dynamical scale separation. Specifically, we investigate a coupling régime that is partially flat, i.e. slowly varying with respect to one set of variables, for example, those of the bath. Further, we study the situation where one of the sets of variables is semiclassically scaled and derive a quantum–classical formulation. In both situations, we propose two schemes of dimension reduction: one based on Taylor expansion (collocation) and the other one based on partial averaging (mean-field). We analyze the error for the wave function and for the action of observables, obtaining comparable estimates for both approaches. The present study is the first step towards a general analysis of scale separation in the context of tensorized wavefunction representations.
Set-theoretic Yang–Baxter equation, braces and Drinfeld twists
Authors: Doikou Anastasia 
Published: August 2021

Abstract
We consider involutive, non-degenerate, finite set-theoretic solutions of the Yang–Baxter equation (YBE). Such solutions can be always obtained using certain algebraic structures that generalize nilpotent rings called braces. Our main aim here is to express such solutions in terms of admissible Drinfeld twists substantially extending recent preliminary results. We first identify the generic form of the twists associated to set-theoretic solutions and we show that these twists are admissible, i.e. they satisfy a certain co-cycle condition. These findings are also valid for Baxterized solutions of the YBE constructed from the set-theoretical ones.
Study on Behavior of Concrete Mixes using Waste Plastics as an alternative for Coarse Aggregates
Authors: Karthik M , Ajey Kumar V G , Keshava Mangala 
Published: August 2021

Abstract
This study proposes the use of waste plastics namely high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene ethylene (PPE) as a replacement to natural coarse aggregates in M20 mix concrete. The study was carried out by testing specimens prepared by replacing recycled waste plastic coarse aggregates (RPCA) produced using semi mechanized process and conventional mix for their workability, compressive strength, flexural strength, split tensile strength and behavior of plastic aggregates at high temperature. Three different set of plastic aggregates were produced by using HDPE LDPE PPE plastic wastes respectively. It was observed that concrete mixes with increasing percent of plastic waste aggregates showed decrease in workability. Compressive strength and flexural strength reduced due to weak Interfacial Transition Zone (ITZ) between plastic aggregates and paste. Tensile strength increased by addition of waste plastic aggregates due to its aggregate property. Exposure of concrete specimens to higher temperature behaved positively in strength parameters. Replacement of 10-20% of RPCA can be made without affecting strength and durability parameters.
Storm Water Purification in an Urban City of India using a Bio-retention Filter
Authors: Mishra S S , Verma V K 
Published: August 2021

Abstract
Bio-retention filtration system is the leading water conservation strategy that makes use of biogeochemical technique within a vegetation ecosystem to retain soil moisture, purify and conserve storm water in urban cities. The present study was aimed at designing a bio-retention filter basin in Kharghar node of Navi Mumbai, Maharashtra, India. The analysis was carried out for both minor (5-year average recurrence interval) and major (100-year average recurrence interval) floods. Total discharge was computed using the rational formula and it was estimated as 0.023 m3/s for minor flood condition and as 0.037 m3/s for major flood condition. The maximum infiltration rate was computed as 0.0047 m3/s considering sandy loam soil as the filter media. A flow width of 1.6 m was considered in designing the bio-retention filter. 100 mm diameter polyvinyl chloride pipe was proposed as they are the best in terms of performance and have advantage over other pipes. No liner is required for filter according to the soil condition of Kharghar. A transition layer of 100 mm gravel was suggested to provide better efficiency and durability for the bio retention system. The vegetation for the bio-retention basin can be Doob or Bermuda grass (Cynodon dactylon) as it has the highest water retention capacity as per Indian conditions.

Published: August 2021

Abstract
The concept and study of a cantilever retaining wall and a cantilever retaining wall with relieving platform with elevations varying from 5 to 8 meters and having a safe bearing capacity of 160 KN/m2 are presented in this paper. It also depicts relative research such as bending moment, safety against overturning and sliding, expense and economy, between the retaining walls. The cost and optimal cost are calculated as part of the relative analysis. Software and analytical results such as bending moment, deflection, and stresses are also discussed in this paper. Laterally acting total earth pressure is depicted to be reduced due to the provision of relieving platform (RP). The retaining wall with relieving platform (RW with RP) is shown to be cost-effective, more stable, and relieve the BM of the stem and heel portions than cantilever retaining wall (CRW). The findings of this research is drawn based on the results obtained using different models prepared in software, comparison of bending moments, requirement of tension reinforcement and these results are verified by manual analysis. The research shows that the CRW with RP is more economical and is more worthy than CRW.

Published: August 2021

Abstract
High-Performance-Concrete made with glass fibers and polypropylene fibers are regarded as Composite Fibre (Glass and polypropylene) Reinforced High-Performance Concrete (CFRHPC). The development of cost-effective state-of-the-art procedures for producing, evaluating, and designing with CFRHPC will enhance the performance for each performance characteristic and can be reliably achieved in the field. This investigation evaluates the effect of cement being partially replaced by combined fly ash and silica fume with glass fibers and polypropylene fibers as an addition to produce high-performance concrete with composite fiber for resistance to sulfuric acid attack for 30, 60, and 90 days. The water to binder ratios of 0.275, 0.300, 0.325, and 0.350 and an aggregate to binder ratio of 1.75 were adopted. Fly ash and silica fume were replaced in the range from 0% to 15% each, glass fibers were added in volume percentages from 0% to 1%, and polypropylene fibers were kept constant at 0.25%. The combined effect of fly ash and silica fume at 5% each as replacement of cement and the addition of composite fiber dosage of glass fiber = 1% and polypropylene fibers = 0.25% for water to binder ratio of 0.275 was found to be the optimum combination to obtain maximum acid attack resistance.

Authors: Deepthi B P , Tuppad Pushpa , Lokesh K S 
Published: August 2021

AbstractThe simulation of hydrologic response of a watershed system using hydrologic models involves calibration and validation process. Carrying out these processes, indeed requires an intensive knowledge on the parameters that impact the hydrologic process in that particular system. In this study, Soil and Water Assessment Tool (SWAT) model was used to simulate the streamflow for upstream of Krishna Raja Sagar (KRS) reservoir, Karnataka, India for the period from 1982-2014. Sensitivity analysis, calibration and validation was carried out using SWAT CUP (SWAT-calibration and uncertainty program) along with SUFI-2 algorithm (sequential uncertainty fitting-version 2) for monthly time scale. The computational efficiency and performance of the model was evaluated using statistical metrics including Nash-Sutcliffe (NS), Coefficient of determination (R2) and Percent bias (P-bias), p factor and r factor. Sensitivity of the parameters were analysed by performing one-at-a-time technique. Calibration of the model was carried out for a period of 10 years i.e., 2002-2011 and validation period was 3 years i.e., 2012-2014 which is one-third of the calibration time period. Using 90 m resolution DEM, landuse and soil maps, observed and 0.25° gridded rainfall along with other observed weather data. NS and R2for calibration and validation period were 0.62, 0.67 and 0.60, 0.60, respectively. Thus, result indicates that SWAT model can be further used to assess the impacts of management scenarios as it effectively simulated the hydrologic response in the KRS catchment.

Abstract
In India, the foremost important prerequisite for a project is performance criteria, economic feasibility and serviceability. The Traditional methods are laborious and don’t seem to be economically viable. Therefore, there is a need to innovate other ways to ensure serviceability as well as economic viability. In this Study, the effects on residual soil’s engineering properties due to bio enzymes are discussed. The soil stabilization with Terrazyme may be a well-established technique that became predominant worldwide due to its performance. There are numerous bio-enzymes that are used for the stabilization of soil like Terra-Zyme, Fujibeton, Renolith, Perma-Zyme, etc. These enzymes are demonstrated to be effective and economical. One among the main advantages of bio-enzymes is that they’re eco-friendly. Once we mix this terrazyme with different types of soils it modifies/improves the soil engineering and index properties. The effectiveness of Terrazyme relies on the quantity of addition, type of soil, and conditions on fields. The utilization of terrazyme for residual soils isn’t well known. In this study, Residual soils obtained from waste water treatment plant is used and its properties were found by conducting tests, it was found that the residual soil was not suitable for any engineering purposes as its UCS was less and it had high water content, hence it was treated with terrazyme in different dosages to supplement the properties of residual soil and obtain its optimum. Treating residual soil with terrazyme improves engineering properties of residual soil to great extent such that UCS of residual soil increased by 250% by adding 2% of terrazyme.

Authors: Anitha B H , Maya Naik S N , Nanjundaswamy C , Divyanand M S 
Published: August 2021

Abstract
Heavy metals, at lower concentrations, have a high atomic weight and density which are toxic and can harm human health and the environment. The level of toxicity typically depends on the age, genetics, gender, the amount of exposure, and the level of immunity of the people. The aim of this study is to determine the extent of heavy metal pollution in Bangalore’s Peenya industrial area (PIA). Heavy metal concentrations were found in the following order: Cr > Cr+6 > Pb > Ni > Fe > Cd. The pollution indices, Heavy metal pollution index (HPI), and Metal index (MI) are used to measure the quality of groundwater based on the ranking. The mean concentration of HPI value is 845.1, which is significantly higher than the critical index value of 100. The percentage of groundwater samples that are over 100 index value is 83.33 percent, which is deemed completely unsuitable for purpose of drinking. The mean MI concentration was 27.1, and it was discovered that 73 percent of groundwater samples were “Seriously Affected” (MI value > 6.0). The findings indicate that the groundwater in these samples is extremely polluted and unfit for human use. It depicts the present state of the PIA in terms of harmful heavy metal pollution in groundwater. The effect of urbanization and industrialization on the study area has played a significant role in the deficit of groundwater quality.

Authors: Reshma T V , Sankalpasri S S , Tanu H M , Nirmala M V 
Published: August 2021

Abstract
Earthquake leads to a disaster by creating massive damage on the surface of the earth. A framed structure reduces the impact of an earthquake. In these types of structures, shear wall plays a vital role by resisting the horizontal shear effectively. The shear wall is the flexural members that effectively resist displacement by providing adequate stiffness to the structure. In this work, the behavior of structure considering shear wall location in a different location under different seismic zones are studied both along the longitudinal and transverse direction. The dynamic response spectrum analysis is done as per IS code and by using design software ETABS. A 20 floor RCC building including base shear, time-period, drift ratio, & displacement are studied. The comparative analysis is done by considering with and without shear walls at different locations. The best feasible position of the shear wall is emphasized in our studies.

Abundance of Polycyclic Aromatic Hydrocarbons (PAHs) in ground water of coastal areas at Sundarban; removal strategy and remediation
Authors: Basak Somjyoti , Sarkar Subhendu , Majumdar Swachchha 
Published: August 2021

Abstract
The confluence of various rivers, swamp forests, salty water abundance makes Sundarban a quite vulnerable ecosystem. This part of the delta areas suffers heavily from fresh water scarcity due to its increased salinity in river bed and polycyclic aromatic hydrocarbons (PAHs)/polyaromatic hydrocarbons/polynuclear aromatic hydrocarbons. PAHs are generally insoluble and found as contaminants in drinking water produced from burning coal, gasoline, trash, tobacco, wood etc. Samples of ground water have been found with more than ten different variants of PAHs by gas chromatography equipment with large amount of dissolved salts which are harmful for human health. A conventional activated carbon packed bed type treatment process has been used to purify the contaminated organic rich raw water by the adsorptive surface contact method of bed. In order to remove fine particles leaching out of the packed bed filter, an ultrafiltration membrane was used to reject those substances which are producing turbidity, such as fine particles, colloids, algae remaining in the water. Total dissolved solids and the PAHs of the ground water reduced significantly by the dual process and further this combination may be used for effective separation of PAHs and cost effective drinking water production.

Published: August 2021

Abstract
Groundwater is a vital natural resource that supports human needs, promotes industrial development, needs farming activities, and helps to maintain ecological balance. Geospatial technologies play an essential role in monitoring, assessing, and conserving groundwater resources. The present study was carried out at Arba Minch town, Rift Valley, southern Ethiopia. A total of eight important groundwater controlling parameters, such as lithology, geomorphology, lineament density, land-use/land cover, slope, precipitation, drainage density, and soil type, were considered to identify suitable groundwater potential zones. The analytical hierarchy process (AHP) technique was used to derive the standard weights for each parameter and its sub-parameters, emphasizing the relative importance of contributing parameters and sub-parameters for groundwater recharge. The present study’s potential groundwater zonation map was divided into three categories: poor, medium, and high. The output has shown about 36%, 24%, and 40% area falls under high, medium, and poor groundwater potential zones. Furthermore, the findings were validated using groundwater level data, which showed a strong correlation. The current study results showed the effect of geospatial techniques and the AHP method in groundwater potential mapping.

Authors: Kanmani S S , Umesha P K , Asha P 
Published: August 2021

Abstract
Nowadays in view of sustainable development it is very much important to reduce the usage of building materials that creates negative impact on environment. There is a necessity to reduce the production of cement content in order to reduce the CO2 content in the atmosphere and which may be achieved by introducing Mineral Admixtures in concrete. This also improves the quality of concrete. Wood ash is found to be one of the suitable mineral admixtures as it has got high pozzolanic activity. But strength of concrete decreases with increase in percentage of wood ash. The aim of this study is to enhance the strength of Steel Fibre Reinforced Concrete (SFRC) in which cement is partially replaced with wood ash. This research work presents the experimental investigation to evaluate the compressive strength and flexural strength with the addition of wood ash from 0 to 20% with increment of 5% in steel fibres reinforced concrete. From the experimental results, for the optimum 10% wood ash achieving considerable benefits in compressive strength and flexural strength.
