Photocatalytic Degradation of Textile Dyes Using Artemisia stelleriana Besser Mediated Nanoparticles
Artemisia stelleriana is widely used as an ornamental plant and belongs to the family Asteraceae. In the current study, A. stelleriana-mediated Zinc oxide newlinenanoparticles (AS-ZnONPs), Silver nanoparticles (AS-AgNPs) and Silver/Zinc oxide bimetallic nanoparticles (AS-Ag/ZnONPs) were synthesised using one-pot method. The UV-Vis spectral analysis revealed characteristic peaks at 358 nm for AS-ZnONPs, newline425 nm for AS-AgNPs, and 357 nm and 473 nm for AS-Ag/ZnONPs. Fourier transform infrared spectroscopy (FTIR) analysis identified phytoconstituents taking part in newlinenanoparticle synthesis, manifesting the presence of alkaloids, phenols, saponins, and newlineflavonoids. The synthesised AS-ZnONPs, AS-AgNPs, and AS-Ag/ZnONPs have a crystalline nature and were confirmed using X-ray diffraction (XRD) analysis. The crystallite sizes of the AS-ZnONPs, AS-AgNPs, and AS-Ag/ZnONPs were 22.54 nm, 18.67 nm, and 10.4 nm, respectively. Spherical-shaped Ag nanoparticles and hexagonal, cylindrical, and spherical-shaped ZnO nanoparticles were synthesized from the leaf extract of A. stelleriana. The average size of the synthesised nanoparticles was 37.6 nm and 71.2 nm for AS-ZnONPs and AS-AgNPs, respectively. On the other hand, spherical-shaped AS-Ag/ZnONPs were synthesized with an average size of 35.3 nm. The photocatalytic degradation activity of AS-ZnONPs showed 93.44%, 47%, 94.76%, 99.9%, and 74.82% degradation for Reactive Blue 220 (RB220), Reactive Blue 222A (RB222A), Reactive Red 120 (RR120), Reactive Yellow 145 (RY145) and newlineReactive Yellow 86 (RY86) dyes respectively after 320 min of UV light exposure. ASZnONPs showed positive results for all five dyes and a better percentage of degradation was observed in a 5 ppm concentration of dye treated with 1 mg/mL concentration of newlineAS-ZnONPs. In the case of AS-AgNPs, RB220 and RB222A dyes showed positive results but no degradation was observed in the remaining three dyes. After 320 min of UV light exposure, AS-AgNPs showed 95.98%, and 100% degradation of RB220 and RB222A dyes respectively. -
Detection of cyber crime based on facial pattern enhancement using machine learning and image processing techniques
Cybercrime has several antecedents, including the rapid expansion of the internet and the wide variety of users around the world. It is now possible to use this data for a variety of purposes, whether for profit, non-profit, or purely for the benefit of the individual. As a result, tracing and detecting online acts of terrorism requires the development of a sound technique. Detection and prevention of cybercrime has been the subject of numerous studies and investigations throughout the years. An effective criminal detection system based on face recognition has been developed to prevent this from happening. Principle component analysis (PCA) and linear discriminant analysis (LDA) algorithms can be used to identify criminals based on facial recognition data. Quality, illumination, and vision are all factors that affect the efficiency of the system. The goal of this chapter is to improve accuracy in the facial recognition process for criminal identification over currently used conventional methods. Using proposed hybrid model, we can get the accuracy of 99.9.5%. 2022, IGI Global. All rights reserved. -

Enhancements to randomized web proxy caching algorithms using data mining classifier model
Web proxy caching system is an intermediary between the users and servers that tries to alleviate the loads on the servers by caching selective web pages, behaves as the proxy for the server, and services the requests that are made to the servers by the users. In this paper, the performance of a proxy system is measured by the number of hits at the proxy. The higher number of hits at the proxy server reflects the effectiveness of the proxy system. The number of hits is determined by the replacement policies chosen by the proxy systems. Traditional replacement policies that are based on time and size are reactive and do not consider the events that will possibly happen in the future. The outcomes of the paper are proactive strategies that augment the traditional replacement policies with data mining techniques. In this work, the performance of the randomized replacement policies such as LRU-C, LRU-S, HARM, and RRGVF are adapted by the data mining classifier based on the weight assignment policy. Experiments were conducted on various data sets. Hit ratio and byte hit ratio were chosen as parameters for performance. Springer Nature Singapore Pte Ltd. 2019. -

QUALITY OF WORK LIFE IN RELATION TO PEOPLE CAPABILITY MATURITY MODEL IN IT AND ITES ORGANIZATIONS
The new found concern for Quality of Work Life in corporate life perhaps has been due to the realization that human resource is the most important asset which must be released and developed. Management viewed QWL programs as a way of reducing costs and improving productivity. The success of any organization depends on how it attracts recruits, motivates and retains its workforce. Human capital is clearly emerging as a key engine of economic growth, and it is evident that the skills and competencies of the workforce impact positively on productivity and competitiveness. In this regard investment in human capital would appear to be a prerequisite to economic success .In this new scenario People capability maturity model offers unlimited potential to develop and maximize human capital and organizational competence in the interest of the firm ,the employee ,the consumer ,the shareholder and not least the family. People capability maturity model is a maturity framework developed at the software engineering institute that guides the organizations in improving the ability to attract, develop, motivate, organize and retain talent.. Economies of the world over and companies facing tough domestic and international markets have been posing a serious challenge to all concerned. This coupled with every changing technology and increased access to information has necessitated studying organization with respect to productivity, efficiency and quality of service rendered. All this demands a new work culture, employee motivation, commitment to the job and organizational goals. Some organizations in the service sector have implemented PCMM to address all these organizational issues. However we have very little information at the grass root level to comprehend QWL, and very little research on QWL Life in relation to PCMM hence this study. Based on the objectives of the study a detailed questionnaire was constructed by the researcher. The questionnaire has three parts measuring demographics, implementation of PCMM and six dimensions of QWL. It was measured on a 5 point likert scale 1 indicating strongly disagree to 5 indicating strongly agree. The Cronbachs alpha reliability for the PCMM and the QWL for the present sample was .80 and above. The questionnaire was completed by 230 respondents using judgmental sampling technique from PCMM implemented and non implemented IT and ITES organizations. It was found that Quality of work life was not significantly higher in companies that implemented People capability maturity model as compared to other companies. Amongst all the dimensions of Quality of work life the only dimension influenced and affected by People capability maturity model was self evaluation of performance .It was found that there was a variation of 20.1% in the Quality of work life. In terms of correlation, the study indicated that there was significant intra relationship between the 6 dimensions of Quality of work Life; significant intra relationship between the People Capability Maturity Model related items and significant interrelationship between 6 dimensions of Quality of Work Life and the People capability maturity model related items. Amongst all the 6 dimensions of Quality of Work Life the only dimension that was significantly different across gender was self evaluation of performance. Females had higher self evaluation of performance as compared to the male counterparts. On the basis of the results attained from the current study we can clearly imply that Quality of work life dimensions is definitely positively influenced, affected and correlated with People Capability Maturity Model though there is no difference in Quality of Work Life among People Capability Maturity Model implemented and Non implemented IT and ITES organizations. The results from the study will have significant implications on the companies that have not implemented People Capability Maturity Model to join the group of People capability maturity model implemented companies as this will help the organizations to prepare the employees psychologically to meet the demands and challenges which otherwise may risk a poor Quality of work life program implementation. Key Words: Organizational behavior, Human Resource Management, People Capability Maturity Model, Quality of Work Life, General linear model. -

A crucial problem in natural language processing is language identification, which has applications in speech recognition, translation services, and multilingual content. The five main Indian languages that are the subject of this study are Hindi, Bengali, Tamil, English, and Gujarati. A Deep Neural Network is introduced in the paper which is specifically made to use Mel-Frequency Cepstral Coefficients (MFCCs) for sophisticated language categorization. The suggested architecture of the model, which includes batch normalisation and tightly linked layers, helps it to be adept at identifying complex linguistic patterns. Comparing the research to the source work [18], promising improvements are shown, highlighting the potential of the model in language detection. 2024 IEEE. -
Wheat Yield Prediction using Temporal Fusion Transformers
In precision framing, Machine Learning models are an essential decision-making tool for crop yield prediction. They aid farmers with decisions like which crop to grow and when to grow certain crops during the sowing season. Many Machine Learning algorithms have been used to support agriculture yield prediction research, but it is observed that Deep Learning models outperform the benchmark Machine Learning algorithms with a significant difference in accuracy. However, though these Deep Learning models perform better, they are not preferred or widely used in place of Machine Learning models. This is because Deep Learning methods are black box methods and are not interpretable, i.e., they fail to explain the magnitude of the impact of the features on the output, and this is unsuitable for our use case.In this paper, we propose using Temporal Fusion Transformer (TFT), a novel approach published by Google researchers for wheat yield prediction viewed as a Time Series Forecasting problem statement. TFT is the state-of-the-art attention-based Deep Learning architecture, which combines high-performance forecasting with interpretable insights and feature importance. We have used TFT to perform wheat yield prediction and compare its performance with various Machine Learning and Deep Learning algorithms. 2023 IEEE. -
Synthesis, Characterization and Studies of Hydrazine Based Polyfunctional Ligands and their Metal Chelates
Eight new hydrazine-based zinc (II), copper (II) complexes were synthesized by reacting Zn (OAc)2.2H2O and Cu(CH3COO)2 with N'??(3,5-dibromo-2-hydroxy benzylidene) benzohydrazide (H2L1) and N'??(3,5-dibromo-2-hydroxy benzylidene) nicotinichydrazide (H2L2) respectively. The synthesized complexes were characterized by CHN analyses, IR, UV and 1H NMR. Based on these studies, square planar and octahedral geometries of the metal complexes were revealed. The synthesized metal complexes named [Zn(H2L1)2](OAc)2, [Zn(H2L1)Py](OAc)2, [ZnL2]2, [ZnL2Py], [CuL1]2, [CuL1Py], [CuL2]2 and [CuL2Py]. The formed metal complexes were investigated for DNA binding studies by fluorescence and UV spectroscopy using calf thymus DNA (CT-DNA) and DNA cleavage studies against pBR322 DNA. Both the ligands and their corresponding metal complexes showed the ability for binding to DNA through intercalation/ electrostatic binding. -
ANN Based MPPT Using Boost Converter for Solar Water Pumping Using DC Motor
The solar DC pump system is simple to set up and run completely on its own without the need for human intervention. Solar DC pumps require fewer solar panels to operate than AC pumps. Solar PV Arrays, a solar DC regulator, and a DC pump make up the Solar DC Pump system. The nonlinear I-V characteristics of solar cells, PV modules have average efficiency compare to other forms of energy, and output power is affected by solar isolation and ambient temperature. The prominent factor to remember is that there will be a significant power loss owing to a failure to correspond between the source and the load. In order to get the most power to load from the PV panel, MPPT is implemented in the converter circuit using PWM and a microcontroller. In order to give the most power to load from the source, the solar power system should be designed to its full potential. 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG. -

NO2 has decreased to a better level. O3 and CO2 are also decreasing but has slight fluctuations. It will take some time to stabilize. SO2 had an increased level till 2017 and has started reducing afterwards. 2021 Ecological Society of India. All rights reserved. -
Impact of Lysinibacillus macroides, a potential plant growth promoting rhizobacteria on growth, yield and nutritional value of tomato plant (Solanum lycopersicum L. F1 hybrid Sachriya)
Plant growth promoting bacteria enhance the growth in plants by solubilizing insoluble minerals, producing phytohormones and by secreting enzymes that resist pathogen attack. The present study was aimed at identifying the potential of Lysinibacillus macroides isolated from pea plant possessing rich microbial rhizobiome diversity in promoting the growth of tomato plant (Solanum lycopersicum L.). Potential of L. macroides in the promotion of S. lycopersicum L. growth by increased shoot length, terminal leaf length and breadth was assessed. Anatomical sectioning of stem and root revealed no varied cellular pattern indicating that the supplemented bioculture is not toxic to S. lycopersicum. Plantlets treated with L. macroides along with organic compost showed an increased total phenol content (17.580.4 mg/gm) compared to control samples (12.440.41 mg/g). Carbohydrate content was noticed to be around 1.3 folds higher in the L. macroides plus compost mixture supplemented slots compared to control sample. Significant increase in shoot length was evident in the L. macroides plus compost supplied slots (23.42.7 cm). Plant growth promoting properties might be due to the nitrogen fixing activity of the bacteria which enrich the soil composition along with the nutrients supplied by the organic compost. Rich microbial rhizobiome diversity in pea plant and the usage of L. macroides from a non-conventional source improves the diversity of the available PGPR for agricultural practices. Further research is needed to detect the mechanism of growth promotion and to explore the plant microbe interaction pathway. Jyolsna et al. (2021). -

Divergent Synthesis of Azole Tailored Compounds and Their Biological and Photoluminescence Applications
Producing a library of diverse compounds with minor structural differences can provide newlinevaluable information related to the structure-activity relationship (SAR), which would not be possible by studying just one molecule. The main goal of the divergent synthesis approach is to efficiently create a collection of valuable compounds, which is different from the traditional methods of making compounds in a linear or convergent way. This approach, known as divergent synthesis, helps select the best compound from the group for its applications. In the newlinecurrent study, the focus is on synthesizing different types of azoles, such as Thiazole Schiff bases, fused tetrazoles, substituted imidazole, and 1H-tetrazoles, and exploring their potential uses in biological and photoluminescence studies. Several methods were utilized to synthesize the derivatives of azole compounds. The synthesized molecules were examined and identified using techniques like 1HNMR, 13CNMR, Mass spectrometry, and IR spectroscopy. After creating a library of molecules, they were evaluated for their potential applications in biology and photoluminescence. The most promising molecule was selected from the preliminary evaluation for further investigation. newlineThiazole Schiff bases were synthesized, and their photoluminescence properties were newlineinvestigated. Among the synthesized compounds, the bromo derivative showed the most promising results in developing fluorescent organic nanoparticles with versatile applications. The compound delivered exceptional results in aggregation-induced emission (AIE), viscochromism, detection of Al3+ions, pH sensing, latent fingerprint detection, and cell imaging. Synthesis of fused azole-derivatives was accomplished using the organo-catalyst 10- newlinecamphor sulfonic acid. Detailed optimization and mechanistic studies were conducted, along newlinewith evaluating the antifungal activity against Candida tropicalis ATCC 10231 for the newlinesynthesized compounds. -
Design of a square-shaped broadband antenna with ground slots for bandwidth improvement
This paper portrays the design of a compact square-shaped microstrip broadband antenna using ground slots. Polygon shaped slots are placed on the ground under the feed line for bandwidth improvement. Similarly, rectangular slots are placed on the square patch for gain enhancement. Effect of these slots on the performance of the antenna in terms of impedance bandwidth, gain and directivity are studied. Results of simulation tests show that a ground slot with proper dimensions placed under the feed line can improve the impedance matching and hence increase the bandwidth without affecting much the performance of the antenna. This compact antenna of size 9.098 x 9.098 mm can be very useful for applications where size is a major constraint. Simple microstrip feed is used to feed the patch. The percentage bandwidth of this antenna is 75.57 %. 2018 Authors. -
