Influence of annealing on the morphological, structural and electrochemical properties of Co3O4 spinel electrodes
Effectual use of energy requires the conversion and storage device with great ability. In this research, Co3O4 nanoparticles are achieved via facile and low-cost reflux method. The consequence of annealing treatment on morphological, structural, and electrochemical behaviors of produced Co3O4 (350, 550, 750 and 950 C) nanoparticles are investigated. XRD analysis exposes the formation of cubic Co3O4 spinel above 300 C annealing temperature. SEM and EDX study demonstrate that the morphology of Co3O4 nanoparticles changes with different annealing temperatures. The electrochemical performance of prepared Co3O4 (350950 C) nanoparticles was determined via charge-discharge experiment, and electrochemical impedance, cyclic voltammetry studies. It exposes that the annealing treatments have an important effect on the specific capacitances. Among them, the optimized Co3O4 (950 C) electrode demonstrates the best capacitive behaviors in the three-electrode cell, which exhibitions the best capacitance value of 1388 Fg?1 at 5 mVs?1 and outstanding cycling capability of 97.2 % capacitance even after 5000 cycles. The asymmetric supercapacitor device assembled by Co3O4 (950 C) displays a capacitance value of 519.3 Fg?1 for 5 mVs?1 and long reversible capacity (92.7 % capacitance retains after 5000 cycles) and a high-power density (26.7 W h Kg?1). These outcomes exposed that the Co3O4 (950 C) nanoparticles could be a perfect candidate for eminent electrochemical application as electrode materials. These results state that Co3O4 nanoparticles are a multipurpose material and thus can be applied in numerous applications namely gas sensors, fuel cells, solar cells, electrochemical sensors, and photocatalysis. 2023 Elsevier Ltd -
Influence of atmospheric plasma spray process parameters on crystal and micro structures of pyrochlore phase in rare earth zirconate thermal barrier coatings
Yttria-stabilized zirconia (YSZ) thermal barrier coatings is most widely used in gas turbine engines applications and its primary role is to protect the underlying base metal from degradation at its high temperature (>1000 C) service environment. While YSZ serves well in this role, materials with higher thermal stability and lower thermal conductivities are required to be developed for attaining higher operating temperatures and thereby higher energy conversion efficiencies. A number of rare-earth zirconates which form the cubic fluorite-derived pyrochlore structures (A2B2O7) where A: La, Gd, Sm, Ce and B: Zr are being developed, some compositions are more attractive due to their good amalgamation of thermal and mechanical properties. However, when these materials are plasma spray coated on metal substrates, the favorable properties are not immediately realized due to various contributing factors such as poor adhesion/cohesion, microstructure (porosity, defects) or even incomplete stabilization or destabilization of the desired phase (crystal structure) after passing through the plasma. In this paper, plasma sprayable powders of zirconate pyrochlores (or with disordered fluorite structures) synthesized from using La and Ce as the trivalent ''A cation, were plasma sprayed onto Inconel 718 substrates, by using different plasma spray parameters. The considerable influence of these spray parameters on the structural phases (analyzed via XRD) and microstructures (studied via SEM on polished cross section metallographs) are presented in detail. 2019 Elsevier Ltd.

Influence of auto mobile magazines on customers In finalizing a choice of vehicle
Automotive journalism is a new field that became popular in media with arrival of world leading vehicle manufacturers to India. There are number of new vehicle manufacturers entered to Indian market in the last decade. Automotive journalism got its grid with the flood of new vehicles in the market. Initially auto mobile news and related articles were just a part of the main news papers or magazines. The situation changed drastically with the introduction of auto mobile magazines in India. Flow of manufacturers towards Indian market is still happening and the number of vehicles from motorcycles to big trucks launching in Indian market is not easy to count. In this situation finding a right vehicle according to the need and budget is not an easy task to the customers who wants to buy a vehicle. Now, Indian vehicle market it so huge and test driving each and every car is not an easy task to choose one. The situation forced the auto mobile journalism and automotive magazines to function as a separate field of journalism. The research tries to find out how far these auto mobile magazines are helpful to the people who want to buy a vehicle. Research then tries to analyse the readers of the auto mobile magazines and influence of magazine on customers in their decision making process. -
Influence of Autonomous Sensory Meridian Response on Relaxation States: An Experimental Study
Multiple studies have stated that autonomous sensory meridian response (ASMR) induces relaxation. ASMR is defined as a static tingling-like sensation across the scalp and back of the head, experienced by some people in response to specific audio and visual triggers like tapping, whispering, and slow hand movements. This study explores the relaxation states and the stress states on which ASMR videos have the highest impact. Data from 60 college students with a mean age of 22 years and a standard deviation of 1.12 were collected for this study, among which 30 were assigned to an experimental group and 30 were assigned to a control group single blindly. The relaxation states and stress states were measured using Smith Relaxation Scale Inventory (SRSI) for the pretest and Smith Relaxation Posttest Inventory (SRPI) for the posttest. The experimental group watched an ASMR video, and the control group watched a neutral video between the pretest and posttest. SPSS version 16 was used for data analysis. The result suggested a significant increase in sleepiness after watching the ASMR video (significant difference). 2021 International Society for Neurofeedback and Research. All rights reserved. -
Influence of behavioural traits on investment decisions
Behavioural traits exhibited by individual investors play a vital role in the investment decisions made by the investor. In this research, the researcher has identified the different behavioural traits shown by different individual investors by their unique characteristics. The study was conducted on a sample size of 811 individual investors from different parts of Bengaluru. The study classified the investment decisions into four aspects and also identified whether investment decisions vary significantlly due to demographic factors. The study further developed a model which explains the linkages between behavioural traits to investment attitude and investment attitude to investment decisions. Review of literature revealed that there exists a gap in the studies in behavioural finance showing the linkages between an investor's behavioural traits and investment attitude and investment decisions. Even though many research happened to identify the personality traits of individual investors, no significant attempt was made to study the linkage between behavioural traits on investment decisions. In this study, an attempt was made to show how individual investors behavioural traits can affect the investment attitude and how investment attitude can affect the investment decision of an individual investor. Result of the study indicated that behavioural traits influences the investment decisions of individual investors. The model developed in the study also proved a linkage between behavioural traits , investment attitude and investment decisions of individual investors with the moderating effect of demograpic factors. -

Influence of career re-entry enablers on job search outcomes: COVID strengthening the disparity virus?
Women in India when faced with the predicament of managing their homes and work, many a times are forced to take a break from their job. On completion of their personal responsibilities when they contemplate re-entering work, they face numerous hindrances. Covid has only raised additional concerns in their career landscape. In this context based on the social cognitive career theory that adopts human agency perspective we theorize that women are not mere bystanders but themselves contribute to their life outcomes through their self-efficacy and resultant job search efforts. Using the components in the SCCT model (Social cognitive career theory) of career self-management (CSM), data from 385 respondents was analysed using Exploratory Factor Analysis, Confirmatory Factor Analysis and Structure Equation Modeling. The study confirmed the direct and indirect relationship between self-efficacy in job search behaviour, outcome expectations, search goals, search actions and the final job search outcome measured through the number of offers received. Implications of this study to the managers, family and society are also discussed. 2021 Ecological Society of India. All rights reserved. -
Influence of Celebrity Endorsement on Women Consumers Purchase Decision of Lifestyle Product - A Study with Reference to the City of Bangalore
Companies have been using celebrities to promote their product and entice the consumers to buy eventually. Since decades this strategy is used by the marketers extensively to attract the consumers to buy the products. Many studies have been done in this area of marketing and most of them talk about celebrity endorsement as a consumer attention seeker. This research talks about the consumer perception about the celebrity in the advertisement and how far do the huge amount of money pumped into celebrity endorsement can be justified? The questionnaires were given to 300 women falling in the age group of 20-40 years residing in the city of Bangalore. By analyzing the data, it strongly came out that celebrity endorsers do not have any effect on the women consumers purchase decision of lifestyle products in the city of Bangalore. It was found that even if the celebrity advertisements get the attention of the women consumer, it may not necessarily convert the attention into purchase decision which depends on many other factors like quality, quantity, experience, price etc. and also one of the most important variables, it depends on the type of product. As a whole the crores of money invested celebrity endorsements cannot be justified in terms of the returns i.e. it may or may not bring a positive impact on the buying behavior of the consumers. In chapter one, the study presents an overview of marketing and consumer behavior. It explains the marketing trends and it is in this century. Then the concept of marketing gave way to the concept advertising and celebrity endorsements. It also talks about celebrity and consumer perception. Chapter two discusses about the various literature reviews relating to the current study. Many studies are citied both by foreign and Indian researchers pertaining to the present study. However, all the possible studies relating to celebrity endorsements are cited. Journals, e-magazines and books were referred. Chapter three discusses about the Research design. The questionnaires were given to 300 women falling in the age group of 20-40 years residing in the city of Bangalore. The sampling technique used here is partially judgmental convenient sampling. Chapter four discusses the analysis and interpretation of the data collected for the research with the help of different statistical and analytical tool. Chi square, F-test and Anova are the statistical tools used for this study Chapter five talk about the findings, suggestions and conclusions for the study. Scope for further study is also given in this chapter. -

Influence of composite mixtures between nematic liquid crystal and porous carbon nanoparticles towards photoluminescence and UV absorbance
The optical parameters of the liquid crystalline materials can be tuned by the dispersion of nanoparticles. Concentration of dopant in the host LC material affects its optical properties significantly, which makes the dispersed system suitable for LC-based devices. In the present investigation, we have studied the effect of different concentrations of nanoparticles on the optical properties of LC, as a guesthost system, where PCNP is guest material and NLC is host material. Porous carbon nanoparticles (PCNPs) were dispersed into the nematic liquid crystal (NLC) in three different concentrations. Optical parameters were measured for pure NLC and NLC-PCNP composites. Photoluminescence (PL) study was performed and it was found that the PL intensity increased for the PCNP dispersed system. High photoluminescence has much importance in the luminescent displays. Full width half maxima (FWHM) were also determined by the Gaussian fitting of PL intensity data. UV absorbance was also measured which gets increased for the PCNP dispersed NLC system when compared to pure NLC. Optical bandgap was found to be reduced after the dispersion of PCNP into NLC. Several other parameters such as absorption coefficient and optical density were also determined. The proposed work may be significant for the liquid crystal displays (LCDs) and other devices which require less bandgap materials. This work may also put some light on the effect of dopants on the LC material in the research based on guesthost system. Increasing the photoluminescence and creating less bandgap materials using carbon nanoparticles is a real challenge, and porous nanoparticles used here overcome this challenge. 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature. -
Influence of Consumers Self Perception on Devaluation of Ugly Produce Marketing Strategies to Reduce Food Waste in the Indian Context
Ugly produce refers to aesthetically imperfect fruits and vegetables and also fruits and vegetables with minor blemishes. Ugly produce does not refer to spoilt, rotten, or germ-infected fruits and vegetables. The basic premise of this study is from self-signaling and self-perception theories. The self-signaling theory states that when people make a choice, they disclose something of their character and personality not just to others, but also to themselves. Self-perception theory (SPT) developed by psychologist Daryl Bem asserts that people develop their attitudes by observing their own behavior and further concluding what attitudes must have caused it. Classically, consumers undervalue ugly produce because of altered self-perceptions; simply visualizing the consumption of imperfect produce acts as a self-indicative signal that negatively affects how consumers view themselves. Due to this, the unattractive produce, even though perfectly edible and with the same taste and nutritional value, is rejected by consumers merely based on shape or some other cosmetic blemish. We discussed the strategies adopted by Indian startups and organizations to reduce food waste. Deep discounting is the strategy followed by food retailers worldwide to sell ugly produce, however, this is not the best strategy as it leads to losses for both the retailers as well as the farmers. We suggested alternative strategies successfully followed by foreign retailers, such as spreading awareness, boosting self-confidence and esteem among consumers, attracting kids, etc., which can be followed by Indian food retailers for selling ugly fruits and vegetables. 2022, Associated Management Consultants Pvt.

Influence of Coronavirus Disease 2019 on human biological timekeeping
To stay in sync with environmental cues, the body's metabolic activities must be rhythmic, and these rhythmic functions are known as circadian rhythms, which repeat every 24 h. People's sleep-wake and eating patterns were interrupted as a result of house confinement, making them more vulnerable to noncommunicable chronic diseases during the coronavirus disease 2019 (COVID-19) period. During the epidemic, there was a greater degree of misalignment with this synchronization. The effects of severe acute respiratory syndrome coronavirus 2 (COVID-19) on the human circadian clock are studied in depth. The literature review was conducted fully online, with the website utilized to collect all of the papers from PubMed, and duplicates were handled only in the first phase. Researchers found that individuals of all ages who are pushed to adjust their daily routines shift to the later chronotype, resulting in lifestyle modifications and an altered biological timing system that contributes to noncommunicable chronic illnesses. Chronic illnesses have bidirectional conductance, which means they can be caused by both environmental and self-modification in daily activity, as was the case during the COVID-19 outbreak, which forced people to stay at home. This review comes to the conclusion that fighting the pandemic may be best done by changing medications and focusing on immune health. 2023 Wolters Kluwer Medknow Publications. All rights reserved. -
Influence of cryogenic treatment of cutting tool inserts on tool wear and surface roughness during milling of Inconel 718
Inconel 718 is a superalloy which is a hard to difficult machining material. It is widely used in industries such as aerospace, defence, energy production, biomechanical and marine. It is used at elevated temperatures and areas where thermal and fatigue stress is high. Due to its superior quality and hard surface, machining of this material becomes a challenge. Cutting tools have failed enormously in milling this material. However, tungsten carbide and ceramics have found some effective features in creating a better machinability. In this paper, microstructure of the inserts have been studied during machining to determine low surface roughness on the material. Cryogenic treatment of the inserts has been carried out to improve tool life and compared with the untreated inserts. 2020 Author(s). -

Detailed explanations have also been given for checking the newlinereliability and validity of the tool and pilot data. -
Influence of Economic Benefits and Social Interaction on Buyer Participation in a Rural Retail Institution: Study of an Indian Periodic Market
Retail institutions offer economic and social benefits to the participants in a market. It is expected that in a less developed economy the social factors influence economic behaviour much more than in developed economies. The rural markets offer increased opportunities for the influence of social factors on economic transactions. This study examined the case of a rural periodic market. To ensure reliability the case study protocol questions reflected propositions developed on the research questions. It was expected that the participants would exhibit the influence of social relations in their market transactions. The results indicated that the economic benefits than social considerations influenced participant behaviour in the rural periodic market. Contrary to expectations not all consumers in a less developed economy exhibit social embeddedness in economic behaviour. Implications are for policymakers involved in planning and regulating rural markets. They need to take into consideration the differing behaviour of consumer groups in designing or regulating retail markets. This study examining the social embeddedness of buyer behaviour in the rural retail context of a less developed economy is presumably the first. 2021 Institute of Rural Management, Anand, Gujarat, India. -
Influence of electrochemical co-deposition of bimetallic Pt-Pd nanoclusters on polypyrrole modified ITO for enhanced oxidation of 4-(hydroxymethyl) pyridine
Bimetallic Pt-Pd nanoparticles were dispersed on polypyrrole coated indium-tin oxide coated polyethylene terephthalate sheets (ITO-PET sheets). The excellent filming property of pyrrole gives a high porous uniform active area for the proper adsorption of bimetallic transition metal nanoparticles. Electrochemical behavior of the modified electrodes was determined using cyclic voltammetry and impedance studies. The physicochemical properties of the modified electrodes were analyzed by scanning electron microscopy, X-ray diffraction spectroscopy, X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. To study the electrochemical oxidation of 4-(hydroxymethyl) pyridine in the presence of sodium nitrate in aqueous acidic medium, the modified electrode was used. It is evident from the study that the modified electrode shows better electrochemical activity towards the oxidation of 4-(hydroxymethyl) pyridine. 2022 The Royal Society of Chemistry.
