Abstract
All over the world desecration is a major factor for livelihood and plantation. There are various types of desecrations and major are air desecration ( or desecration), water desecration or water desecration, Industrial desecration, noise desecration, urban desecration etc. In India Act 1981 prescribes various functions for the Central Desecration Control Board (CPCB) at the open level and state desecration control board at the state level about air desecration. Act 1974 gives about water prevention and control desecration. Act 1986 section 2(a) explains noise desecration under rules, 2000. In this paper we are collected data of air pollutants such as particulate matter of 2.5 microns or less. particulate matter of 10 microns or less, Nitrogen Monoxide, Nitrogen dioxide, chemical compound of oxygen and nitrogen, Azane or Ammonia, Carbon Monoxide, Sulfur dioxide Ozone,Benzene, Toluene, Xylene, AQI, AQI_Bucket. For these variables we are fitted Machine Learning models such as Naive Bayes Classifier, CV Parameter Selection, K-nearest neighbours, J48 and Hyper Pipes using WEKA software. Detailed accuracy for models like TP ratio, FP ratio, precision, F-measure, ROC area are estimated. Using Root average square error, Average absolute error, we examine which is the best model.
A review of Economic Order Quantity modelling, their extensions and applicability
Authors: Raju Uma 
Published: September 2022

Abstract
Inventory control and management is an important task for every organization, wherein they need to determine the order quantity and order period to maintain enough inventory to meet the demand. The original Economic Order Quantity (EOQ) model was developed by Ford W. Harris to address this problem and determine the optimal order quantity that helps in optimizing the cost incurred by the organization. Even though this model gives a very good approximation on these parameters, there were many inherent restrictions to the model that were based on un-realistic expectations. In over a century since its original publication, many researchers have made extensions to this model to address the limitations and align it with real world scenarios. In this review paper, we intend to provide a representation of the original EOQ model, its limitations and the various extensions made to the model to address these limitations.

AbstractPrevious research findings have shown that an unhealthy diet can trigger the progression of tumors leading to a high mortality rate. Also, it has been noted that the hormonal changes caused in the human body support the proliferation rate in several kinds of cancer. In the present research, the light is thrown on breast cancer. Estrogens are a class of hormones that play an essential function in women’s proper sexual and reproductive advancement. Moreover, studies have revealed that a woman’s risk of breast cancer is proportional to the Estrogen and testosterone produced by the. Long-term and/or high-level exposure to these hormones has been associated with an increased risk of breast cancer. A novel mathematical model is framed to analyze the effect of estrogen levels on cancer advancement in females integrated with the effect of the unhealthy diet model. The levels of Estrogen are fixed to explore the other cell densities. The research concluded that the level of estrogen produced has a remarkable effect on the immune system in the case of a patient with breast cancer consuming an unhealthy diet.
Terahertz probe assisted failure mechanism analysis of silver nanowire film heaters under high working power
Authors: Wang Mengjiao , Ji Shulin 
Published: September 2022

Abstract
The silver nanowire film heaters have the breakdown problem under high working power. It is related with the Rayleigh instability of the silver nanowires and with the electromigration of silver atoms under high electric field localized within nanowire diameter due to the percolation conduction of the silver nanowire films. During the instability of the two structures, the carrier is confined to the nanostructure and suffers different backscattering, which is studied by non-contact Terahertz (THz) spectroscopy. In this paper, structural collapse of heaters presented by THz spectroscopy is to be studied in depth, and the Rayleigh instability and electromigration on device failure are paid attention to by extracting the characteristic parameters of THz time domain spectroscopy and by evaluating the changing trend of the characteristic parameters during device failure. Failure mechanism of heaters under high working power is to be revealed and countermeasures are to be developed. The implementation of this project could drive forward further research on intelligent heaters, which is valuable for scientific research and industrial applications.
Picosecond imaging at high spatial resolution using TOFPET2 AISC v2d and microchannel plate detector
Authors: Sudjai T. , Lapington J.S. , Leach S.A. 
Published: September 2022

Abstract
Microchannel plate-based detectors provide advantages over their solid-state counterparts for applications where a combination of virtually zero noise photon-counting, large format, short wavelength sensitivity with high resolution timing and imaging are required. Solar-blind applications, Cherenkov detectors for high energy physics, and UV astronomy are such fields. The application to Cherenkov detection is particularly demanding, requiring time resolution below 100 picoseconds combined with imaging and high throughput. This requires the readout to combine high spatial and temporal event resolution at high rates necessitating a parallel readout approach. We describe a readout design comprising a pixellated readout array instrumented using multi-channel fast timing electronics and incorporating charge centroiding to achieve sub-pixel spatial resolution. We present experimental results of the relationship between time-over-threshold and signal amplitude and a centroiding image obtained with an MCP detector using a pixellated readout geometry. The readout was optimised for a fast electronics implementation based on the TOFPET system, a multi-channel all-in-one ASIC originally designed for time-of-flight PET using silicon photomultipliers.
Optimization of the iterative deconvolution correction method applied to ionization chamber response for small field dosimetry measurements

Published: September 2022

Abstract
This study aims to optimize the iterative deconvolution correction of air-filled
ionization chamber measurements with limited spatial resolution for photon beam dosimetry. The
ionization chamber volume effect could be explained by the inhomogeneity of the absorbed dose
in its sensitive volume, leading to a volume averaging effect acting as a convolution kernel
K(x). Therefore, the “true” dose profile Pt(x) can be deduced by deconvolving measured
1D profiles Pm(x). The Semiflex 3D ionization chamber type PTW 31021 was studied for beams
with flattening filter (WFF), while the SNC125c ionization chamber was investigated for
flattening filter free (FFF) beams. The deconvolution distributions were compared for the
first ionization chamber with reference dose profiles calculated by Monte Carlo simulation and
for the second ionization chamber with reference measurements obtained using a diode EDGE
detector, suitable for small field applications. The convolution kernel was assumed to be a sum
of normalized Gaussian and Lorentz distributions parametrized by the pair (σicλic
). Good results were obtained with respect to the γ
index 2.0%/0.5 mm
criterion for the field sizes 6 × 6 mm2, 10 × 10 mm2 and
20 × 20 mm2. The highest agreement between reference and corrected measurement data
was obtained by using the Gauss-Lorentz distribution parameters (1.92 mm, 0.80 mm) and (1.90 mm,
0.90 mm) for the ionization chambers Semiflex 3D type PTW 31021 and SNC125c, respectively.
Peptide-based assembled nanostructures that can direct cellular responses
Authors: Huang Haofu , Kiick Kristi 
Published: September 2022

Abstract
Natural originated materials have been well-studied over the past several decades owing to their higher biocompatibility compared to the traditional polymers. Peptides, consisting of amino acids, are among the most popular programmable building blocks, which is becoming a growing interest in nanobiotechnology. Structures assembled using those biomimetic peptides allow the exploration of chemical sequences beyond those been routinely used in biology. In this review, we discussed the most recent experimental discoveries on the peptide-based assembled nanostructures and their potential application at the cellular level such as drug delivery. In particular, we explored the fundamental principles of peptide self-assembly and the most recent development in improving their interactions with biological systems. We believe that as the fundamental knowledge of the peptide assemblies evolves, the more sophisticated and versatile nanostructures can be built, with promising biomedical applications.
‘Bethe-ansatz-free’ eigenstates for spin-1/2 Richardson–Gaudin integrable models

terms all have distinct coupling strengths. While insuring that integrability is maintained in the presence of an external field excludes the elliptic XYZ model which is only integrable at zero field, this work still covers a wide class of fully anisotropic (XYZ) models associated with non skew-symmetric r-matrices. The eigenstates, as constructed here, do not require any usable Bethe ansatz and therefore: no proper pseudo-vacuum, Bethe roots, or generalised spin raising (Gaudin) operators have to be defined. Indeed, the eigenstates are generically built only through the conserved charges which define the model of interest and the specification of the set of eigenvalues defining the particular eigenstate. Since these eigenvalues are, in general, solutions to a simple set of quadratic equations, the proposed approach is simpler to implement than any Bethe ansatz and, moreover, it remains completely identical independently of the symmetries of the model. Indeed, the construction removes any distinction between XYZ models and XXZ/XXX models and, generically, that between models with or without U(1) symmetry so that any difficulties associated with the use of a Bethe ansatz in any of these cases are avoided.

Published: September 2022

Abstract
In the present work, modification of aluminum-silicon (Al-Si) alloy based advanced composite surface is performed using laser texturing (LT). Surface texturing (ST) with different patterns, i.e., dimple (T1), square (T2), triangular (T3), and line hatched (T4) textures are done on the alloy surface and its impact on the mechanism to reduce friction and wear are investigated. The tribo tests are conducted at 10 N load, Hertzian contact pressure (Pmax) 708.7 MPa, 1 mm stroke length, frequency 50 Hz and sliding distance (SD) up to 450 m. The tribological behavior of the non-textured surface (NTS) and textured surface (TS) are examined under dry sliding conditions (DSC) and two lubricating sliding conditions (LSC) comprising of virgin PAO-4 (Lube-1) and PAO-4 + 1 wt% graphene nanoplatelets (Lube-2). T2 texture reveals a 49.53%, 69.21% and 44.91% decrease in friction coefficient(COF) and 58.1%, 43.74% and 83.86% decrease in wear volume (WV) than the NTS for DSC, Lube-1 and,Lube-2, correspondingly. Results show that ST improved friction efficiency, and shortened the running-in period. The current study results help to provide in-depth interpretation of micro-texturing and its relationship w.r.t. tribological characteristics.

Published: September 2022

Abstract
The development of photo/electroactive catalysts sustainably producing hydrogen from water splitting and selectively hydrogen peroxide is of paramount importance to alleviate climate change effects. Herein, an anionic cobalt porphyrin (CoP) derivative is electrostatically interfaced with a positively charged modified molybdenum disulfide (MoS2), forming CoP/MoS2, which is accordingly employed as nonprecious photo/electrocatalyst for water oxidation reaction (WOR) and selective H2O2 production. According to the results, CoP/MoS2 shows remarkable bifunctional photo/electrocatalytic performance for WOR and 2e− pathway O2 reduction reaction (ORR) in alkaline electrolyte. Upon visible light irradiation, electrochemical measurements on a fluorine-doped tin oxide (FTO) coated glass electrode reveal an onset potential of 0.595 mV (ORR) and 1.575 mV (WOR) vs. reversible hydrogen electrode, being improved by approximately 80 mV, in both cases, compared to the dark conditions. Notably, the use of the FTO set-up not only enabled us to evaluate the photo/electrocatalytic activity of the CoP/MoS2 nanoensemble but also mimics the practical conditions in photo/electrochemical devices. The outstanding bifunctional photo/electrocatalytic performance of CoP/MoS2 is attributed to (a) the use of CoP as versatile single-atom molecular catalyst and photosensitizer (b) the strong ion-pair interactions between cationic modified MoS2 and the anionic CoP derivative, which prevent aggregation, ensuring better accessibility of the reactants to cobalt active sites, and (c) the co-existence of 1T and 2H phase at modified MoS2, offering improved electrical conductivity and intrinsic electrocatalytic activity along with enhanced intraensemble electronic interactions upon illumination. This work is expected to inspire the design of advanced and low-cost materials for the sustainable production of renewable fuels.

Abstract
A new long-pulse high electron temperature (

T

e

) regime has been achieved on experimental advanced superconducting tokamak by pure radio frequency heating. In this new scenario, there are mainly two confinement states involving two magneto-hydrodynamic (MHD) modes, one of which is identified as m/n = 1/1 kink mode (where m and n are the poloidal and toroidal mode numbers, respectively). The frequency evolution of the kink mode is investigated through the three-dimensional, toroidal, and nonlinear Hall-MHD code CLT. We firstly find that the frequency of the m/n = 1/1 kink mode significantly increases during each sawtooth crash and then confirmed it through the experimental data. The simulation results indicate that the increase of the mode frequency is mainly due to the significant increase of the electron diamagnetic frequency nearby the reconnection region. We have also observed the internal transport barrier (ITB) during the m/n = 1/1 kink mode. To further investigate this m/n = 1/1 kink mode in this new regime, the multi-scale interactions between the m/n = 1/1 kink mode and turbulence are discussed.
Influence of ultrasonic treatment on heat transfer in the heat exchanger

Published: September 2022

Abstract
This paper deals with the influence of guided ultrasonic waves on heat transfer. Two piezoelectric transducers, whose structure can be vibrated at different powers and at their resonant frequency in the ultrasonic range of 27–45 kHz, were placed on the plates of a heat exchanger to inhibit the formation of a mineral deposit. These waves were set to diffuse only into the metal plates of the exchanger. During these tests, an increase in the heat transfer between the two fluids was directly observed on the continuous recording of the outlet temperature, on the calculations of the global exchange coefficient, and on the flow exchanged between the two fluids in the laminar regime. Tests are presented in this article, tests in the presence of the 45 kHz transducer, another with a 27 kHz transducer, and which combines the two have a different positioning on the exchanger. The results obtained from the ultrasonic guided waves are similar to the classical ultrasonic waves.
From the elastocaloric effect towards an efficient thermodynamic cycle

Published: September 2022

Abstract
In recent years, elastocaloric cooling technology has been considered as one of the most promising alternatives to vapor compression technology. Given that elastocaloric technology is only in the early stages of development, a uniform method for evaluating the elastocaloric effect has not yet been established, and the thermodynamics of different elastocaloric cooling cycles have not yet been studied in detail. Therefore, the main goal of this work is to investigate these two important areas. Here, multiple thermodynamic cycles were studied, focusing on the parameters of the holding period of the cycle, which is essential for heat transfer between the elastocaloric material and the heat sink/source. The cycles were applied to commercially available superelastic thin-walled NiTi tubes under compressive loading and a thin NiTi wire under tensile loading. Isostress cycles with constant stress throughout the holding period, isostrain cycles with constant strain throughout the holding period and no-hold cycles (without a holding period) were studied across multiple stress/strain ranges. Based on the experimental results, a previously developed phenomenological model was applied to better understand and further evaluate the different cycles. The results revealed that the applied thermodynamic cycle significantly affects the thermomechanical response and thus the cooling/heating efficiency of the elastocaloric material. We show that by using isostress cycles and partial transformations, a Carnot-like thermodynamic cycle with improved heating/cooling efficiency can be generated. By applying the isostress cycles, an adiabatic temperature change of 30.2 K was measured, which is among the largest directly measured reproducible adiabatic temperature changes reported for any caloric material to date. Ultimately, this study intends to serve as a basis for establishing a uniform method for evaluating the elastocaloric effect in different materials that would allow for reliable and accurate one-to-one comparison of the reported results in the rapidly growing field of elastocalorics.
A Causal Mediation Analysis for Investigating the Effect of a Randomized Cash-Transfer Program in Nicaragua
Authors: Charters Thomas J , Kaufman Jay S , Nandi Arijit 
Published: September 2022

Abstract
Mediation analysis can be applied to data from randomized trials of health and social interventions to draw causal inference concerning their mechanisms. We used data from a cluster-randomized trial in Nicaragua, fielded between 2000 and 2002, to investigate whether the impact of providing access to a conditional cash-transfer program on child nutritional outcomes was mediated by child health check-ups and household dietary diversity. In a sample of 443 children 6–35 months old, we estimated the controlled direct (CDE) effect of random assignment on measured height-for-age z scores had we intervened so that all children received a health check-up and had the same level of household dietary diversity, using inverse-probability weighted marginal structural models to account for mediator-outcome confounding. Sensitivity analyses corrected the CDE for potential nondifferential error in the measurement of dietary diversity. Treatment assignment increased height-for-age z score by 0.37 (95% CI: 0.05, 0.69) standard deviations. The CDE was 0.20 (95% CI: −0.17, 0.57) standard deviations, suggesting nearly one-half of the program’s impact on child nutrition would be eliminated had we intervened on these factors, although estimates were relatively imprecise. This study provides an illustration of how causal mediation analysis can be applied to examine the mechanisms of multifaceted interventions.
Probable drug-induced clitoral priapism due to potentiating effects of pregabalin and duloxetine
Authors: Nguyen Joanne , Chin Justin J , Blalock Meredith 
Published: September 2022

Abstract

Purpose
The following case report discusses probable clitoral priapism secondary to duloxetine and pregabalin. While this is a rare adverse effect, it is possible given the mechanism of action and potentiating effects of the combined therapy. This adverse drug reaction was reported to MedWatch and shows that additional research into the physiology of clitoral erection is warranted given the scarcity of information on how drugs influence this reaction.

Summary
A 53-year-old African American female with uncontrolled anxiety was started on duloxetine. Pregabalin was added 1 month later due to continued feelings of anxiety. Three weeks later, the patient reported symptoms of clitoral pain, as well as a swollen, tender, and erect clitoris. These adverse effects remained for 4 days, prompting the patient to present to the emergency department where a physical exam was completed with no significant finding except as noted above. Pregabalin was immediately discontinued by the attending physician based on the probability that the swelling was likely drug-induced clitoral priapism. During follow-up, the patient continued to note clitoral erection and pain. The psychiatric pharmacist tapered off duloxetine over 2 weeks with resolution of symptoms. In an examination of the mechanism of action of both drugs, pregabalin can amplify duloxetine’s inhibitory effects on voltage-dependent calcium channels. It is likely this mechanism that causes smooth muscle relaxation and led to clitoral priapism.

Conclusion
This case suggests that pharmacological agents affecting vasoconstriction through serotonergic receptors or calcium-dependent channels can also influence clitoral erection.
