Abstract
In this work, the position-dependent mass Schrödinger equation is solved with the Pöschl-Teller-like potential in the presence of magnetic and Aharonov–Bohm (AB) flux fields. The BenDaniel-Duke ambiguity parameter ordering is used to formulate the Hamiltonian operator for the system. An approximate analytical equation of the bound-state energy spectrum is obtained using the parametric Nikiforov-Uvarov solution technique along with a Pekeris-like approximation scheme. With the aid of the obtained equation for the energy levels, analytical formulas of magnetization and magnetic susceptibility at zero-temperature are derived and subsequently used to predict the physical properties of diatomic substances including the ground state H2, HCl, CO and LiH molecules. The expression for the bound-state-energy spectrum is used to generate numerical data for the molecules. The computed energy eigenvalues agree with the literature on diatomic molecules. The study revealed that in the absence of the external fields, the energy eigenvalues and magnetic susceptibility of the system are degenerate. However, with only a low intensity AB field, the degeneracy is completely eliminated from the energy states of the molecules.
Multivariate control charts for calibration of hydrophones using the Mahalanobis statistic
Authors: Crocker S E , Slater W H , Bergeron M A 
Published: August 2023

Abstract
Statistical analysis of data to ensure the validity of calibrations can be challenged when the measurement model describes a process and result that spans a high-dimensional parameter space. Calibration of hydrophones presents one such case whereby the sensitivity to acoustic pressure is calculated using measured values for several different quantities and the result is needed at many excitation frequencies distributed over a large bandwidth. We addressed this challenge by developing a multivariate statistical analysis procedure that supports efficient and effective process control for hydrophone calibrations. We first characterize the in-control condition by the mean and covariance of measurements expressed in a p-dimensional parameter space using a curated training data set. We then test subsequent measurements against a control limit using Hotelling’s T
2-test to compare the current measurement process to the training data. We report a case study for secondary calibration of hydrophones spanning a frequency range of 1 kHz–200 kHz where we detected an emergent defect in the laboratory’s calibrated reference hydrophone by inspection of data presented in multivariate control charts. Process control data collected during calibration services exceeded the control limits in intermediate and high-frequency bands by factors of 5.1 and 11.2, respectively. The process remained in control for the low-frequency band. These observations were consistent with misalignment of the reference hydrophone’s sensitive element, which we confirmed upon disassembly, inspection and repair of the instrument.

Abstract
We report on the observation of spatially asymmetric turbulent structures with a long radial correlation length in the core of high-collisionality H-mode plasmas on DIII-D tokamak. These turbulent structures develop from shorter wavelength turbulence and have a radially elongated structure. The envelope of turbulence spans a broad radial range in the mid-radius region, leading to streamer-like transport events. The underlying turbulence is featured by intermittency, long-term memory effect, and the characteristic spectrum of self-organized criticality. The amplitude and the radial scale increase substantially when the shearing rate of the mean flow is reduced below the turbulent scattering rate. The enhanced long-radial-range-correlated (LRRC) transport events are accompanied by apparent degradation of normalized energy confinement time. The emergence of such LRRC transport events may serve as a candidate explanation for the degrading nature of H-mode core plasma confinement at high collisionality on DIII-D tokamak.

Abstract
This study aim is to develop further an ion cyclotron range of frequencies (ICRF) method of plasma production in stellarators based on the minority heating. The previous studies demonstrate production of low density plasma (9.5 × 1017m−3) at low power of up to 0.2 MW. The higher ICRF heating power experiments become possible after introducing a programmable ICRF power ramp up at the front of the ICRF pulse. With this trick, all the shots went with the antenna voltage within the safe range. Increase of the ICRF power predictably results in increase of the density of produced plasma. Without pre-ionization the plasma density achieved was 6 × 1018 m−3 which is 6 times higher than in previous experiments. However, the electron temperature was not high, the light impurities were hot fully stripped, and there were no recombination peaks after termination of the ICRF pulse. Plasma density is too low to provide good conditions for efficient plasma heating. For the reference, the ICRF heating of high density cold plasma prepared by electron cyclotron resonance heating is performed. Both electrons and ions were heated to high temperatures, and this plasma state is sustained. The antenna–plasma coupling was much better which result in larger heating power with the lower antenna voltage.

Abstract
The most crucial element to take into account when developing operations in the building sector is steel. Therefore, it is essential to assess the state of steel in real-time to prevent failure later on in the structure’s useful life. When a structure’s strength declines over time, structural issues such as overloading, material deterioration, and physical damage may be discovered. If these issues are not addressed, the structure’s estimated lifespan may be shortened. For the purpose of evaluating the physical state of all structures that are 15 to 30 years old, the Indian government authorized a structural audit. The non-destructive testing techniques are adopted while conducting a structural audit on a steel structure. such as Vernier Thickness Caliper Test, Dye-Penetration Test, Ultrasonic Thickness Gauge, and Visual Inspection. The carbonation of concrete is one of the main reasons for the corrosion of reinforcement. The carbonation and corrosion deterioration model is developed and the Life Evaluation of Structure is showcased in this paper. The Sangam Steel Plant in Wardha, Maharashtra, undergoes a structural audit to determine the steel structure’s physical condition and determine the most cost-effective rehabilitation options to extend the structure’s life.

Abstract
Population of world increase day by day and it may raise more than 9 billion upto 2040. Fresh potable water for drinking, domestic and agricultural use is life line of human, animals, plants. In present situation most of the countries fight with this scarcity of potable water. And in future situation will be very tuff. Construction of engineered wetlands is concept based on natural wetlands. Now days reduction of natural wetlands cause of water pollution, soil pollution and reduction of bio diversity. Processes of engineered wetlands surpass the problems of natural wetlands and will increase the capacity of waste water treatment process. Constructed wetland treated waste water on basis of natural process which is completely non-hazardous, eco-friendly and non-consumption of energy. At in present condition, land is costlier and most of the wetlands vanish due to effective use of lands, hence we found various hazardous changes like ground water depletion, increase of greenhouse gases (Methane, CO2), disturbance/vanishing of bio diversity lived into wetlands. Wetlands are also play a major role for flying animals, water animals for food chain and food web. Development of wetland is always cost effective, durable as compare to others conventional waste water treatments and engineered developed waste water treatment plants. Now a day’s, it very necessary to develop the techniques to reduce carbon foot prints and adopts those technology completely based on natural processes. Nature provides the techniques to humans but it need some scientific and engineered way to develop. Engineered developed wetlands have beautified locality/area and without any kind of odour, smell, nuisance of flying kits etc. Wetlands with pollution absorbent plants create bio diversity and beautified locality.

Abstract
Concrete is the second most used material on the earth after water. The current era of concrete making material like the coarse and fine aggregate need alternatives to overcome the demand. In this present study, artificial fine aggregate or artificial sand (AS) as an alternative to fine aggregate has been investigated. The parameters studied in this study to investigate the AS effect of concrete are slump, modulus of rapture, compression strength, split-tensile strength, and shear strength. The experimental results show that the fresh properties and compression strength show significant changes when the replacement dosage of natural fine aggregate or natural sand (NS) increases with AS. However, the other parameters, namely shear strength, tensile strength, modulus of rapture, and AS replacement, also positively impacted concrete. The multi-criteria decision-making technique was used to determine the prepared mixtures’ optimum mixture. Based on TOPSIS analysis, it is confirmed that the replacement of AS is 25% more effective. The study revealed that 100% NS replacement is also possible by AS, but a suitable admixture is required for workability.

Published: August 2023

Abstract
Expansive soils are predominant in many parts of the world. Expansive soil treated as problematic soils, as economic and design a safe slope on expansive soils is major challenge for civil engineers. Expansive soils were compacted under unsaturated condition, in various construction projects. Major failures reported in many countries around the world are due to swell shrinkage characteristics causing unstable slopes. Fills and compacted soils have an inherent suction when they are first compacted. The suction is the most important factor which affects the shear strength of unsaturated soil. variation of suction in unsaturated soil is an important factor considered for solving issues like slope stability and bearing capacity failure in unsaturated soil. Rainwater infiltration are major triggering factor for failureof expansive soil slopes. The strength of unsaturated soil changes with water evaporation and infiltration. Due to infiltration of rainwater into the soil a significant change in the pore water takes place. Hence, this fluctuation in pore water pressure responsible for the distinct mechanical behavior of unsaturated soil under different Geotechnical problems.
A numerical modeling was done with Plaxis LE software, considering parameters of unsaturated soil. As the changes in pore-water pressure and moisture content are a function of the flow of moisture through the soil-atmosphere boundary.The effect of soil type, rainfall intensity, location of ground water table, permeability functionsareconsidered to reproduce the soil-atmosphere interaction. Obtain results illustrates the combine effect of suction and increase of saturation due to rainfall on slopes. It was observed that rainfall increase the induced matric suction and increase the positive pore water pressure finally results in slope failures.

Abstract
While constructing a building the most important factor to be considered is its strength. Strength against different types of load that will be act on the structure after absolute construction. The most important type of load to be considered while construction is lateral load, cause not every structure can sustain lateral loads, especially high-rise structures build on earthquake prone areas. In order to resist lateral loads on such areas either the structure should have columns of higher section or we need to add shear wall or bracing to the structure. Bracing and shear wall provide lateral support to any structure. Bracing as well as shear wall takes the extra load of columns and beams during an earthquake which helps in load balancing. In this paper we have made a G+7 building and did earthquake analysis on STAAD.PRO software as per zone V. When earthquake load is applied to the structure without braces some of the columns an beams fail so in order to make the structure stable we applied braces (X and Diagonal) to the same structure and then compared the three models based on maximum storey displacement, maximum storey drift, bending moment, shear force and base shear.

Authors: Burile A. N. , Khandeshwar S. R. 
Published: August 2023

Abstract
Activated carbon (AC) produced from the cotton stack with activating zinc chloride (CSZn) in muffle fernane under nitrogen atmosphere in 600°C. The chemical activation has increased its surface area. It shows a strong capacity of adsorption for the removal of nickel from an aqueous solution due to its enhanced porous structure and higher pHpzc value. The ability was studied using a variety of variables, such as varying the pH, concentration, temp, time of contact, and dose of adsorbent, and optimal conditions were found at pH 8, 10 mgL-1,90 min, 40°C and 200mg respectively. The removal of 75% of the Ni++ ion at a starting concentration of adsorbent at 100 mg was observed. The experimental adsorption results suit the Langmuir isotherm in the isotherm investigations fairly well. The efficient and affordable generation of activated carbon utilizing cotton stack agro-waste may be the solution for the issue of disposing of agricultural trash.

Abstract
The stone industry’s waste is to blame for a slew of environmental issues. The stone waste is rarely degradable and contribute to environmental hazards. The flowing of stone slurry with rainwater also pollutes the water bodies. This contaminated water has an impact on irrigation and drinking water supplies. Fine particles of by inhaling the stone slurry that flew with the air blasts, a major health concern was created. Fine particles of stone slime buildup on the leaves of plants, trees, and other vegetation, causing aesthetic issues. As 70 percent of wastes and only 30% of major product recovery contribute to the highest amount of indestructible wastes, plants and trees perish as a result of stone dust accumulation over leaf vegetation. The most effective method of reducing stone slurry pollution is to use it in bulk. The building sector is the only industry that can consume substantial amounts of stone slurry. The fineness modulus is 0.91, and the specific gravity is 2.61. Stone slurry replaces 30% of the sand in Cement Concrete, resulting in more strength than the Control, which is 1:1.5:3 Cement Concrete with 0% Stone slurry. In the building business, stone slurry may be easily used to make cement concrete.

Abstract
Concrete is widely used as construction material because it’s high durability and fire resistance. When any structures exposed to fire, its room temperature will raise continually, which cause deterioration of concrete structures. During high temperatures concrete loss it structural capacity and it may require strengthen and rehabilitations. This paper is an efforts to investigate the effect of elevated temperature on conventional concrete and concrete with granulated blast furnace slag( GBFS) as partial replacement of fine aggregate in proportions of 20%, 40 % and 60 % and 1 % steel fibers.

This experimentation shown the strength of concrete with GBFS 40 performs well at all elevated temperatures as compared with conventional concrete.
Effect of cobalt addition on wear behaviour of TiB2 coating produced by TIG cladding process
Authors: Kumar Ravi , Kumar Das Anil 
Published: August 2023

Abstract
In this paper, the mechanical and tribological characteristics of TiB2 ceramic coating with and without cobalt (Co) addition developed using tungsten inert gas (TIG) cladding process on AISI 304 stainless steel (SS) were investigated. The effect of TIG process conditions as well as cobalt (Co) content on the microstructure, microhardness and resistance to wear were investigated systematically. The phase identification, microstructure, and elemental distribution map of the clad layer formed on the surface of an AISI 304SS substrate were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS), respectively. Vickers microhardness testing apparatus and a pin-on-disc tribometer were used to evaluate the microhardness, resistance to wear, and coefficient of friction (COF), respectively. The result demonstrates that a dense and defect-free composite coating with a strong metallurgical bond to the substrate is possible. The average microhardness of the TiB2 ceramic coating without Co addition was 1704 HV, and the average wear rate was 15.1576 × 10−9 g N−1-m−1. In contrast, the TiB2 ceramic coating with Co addition exhibited an improved average microhardness of 1860 HV and a reduced average wear rate of 22.7364 × 10−9 g N−1-m−1, while the AISI 304SS substrate had an average microhardness of 216 HV and an average wear rate of 200.45×10−9 g N−1-m−1. The conclusion is that the TiB2 ceramic coating with Co addition exhibited superior mechanical and tribological characteristics, demonstrating its suitability for use in wear-resistant components. The higher microhardness of the TiB2 ceramic with Co-added coating indicates enhanced hardness and potential resistance to deformation, while the lower wear rate suggests improved durability and the ability to withstand frictional forces. Therefore, the TiB2 ceramic coating with Co addition shows promise for applications where wear resistance is crucial.
