Adoption and Usage of Artificial Intelligence in Food Processing Industries
In recent years, technological changes and advancements have forced Fast Moving Consumer Goods (FMCG) industries, especially food processing, to redesign their functionality. This includes the integration of technologies like Artificial Intelligence (AI) to enhance performance. Future trends in the food processing industry will be shaped by sustainability, efficiency, traceability, wellness, safety, hygiene, health, and newlinetransparency. Food processing industries are compelled to embrace digitalization in the newlinecurrent era of globalization and digital transformation. AI encompasses programs, newlinealgorithms, robotics, drones, data mining, cloud computing, sensors, driver-less newlinevehicles, the internet of things, digital platforms, and machines, representing a new newlinelevel of intelligence. AI aims to replicate human reasoning and problem-solving newlinecapabilities, leading to task automation, increased efficiency, and reduced human newlineeffort. The growth of AI is reshaping the food processing industry, with potential newlineapplications spanning from cultivation, supply chain management, storage and safety, newlineHuman Resource Management (HRM), and Customer Relationship Management (CRM). Integrating and adopting AI in food processing can address unique challenges and offer substantial benefits across these functions. While large-scale food processing newlineindustries have made significant progress in adopting AI systems, small and mediumscale food industries are also integrating AI technology. The current research study employs a quantitative research methodology and obtained data from 320 small and medium-scale food processing industries employees in the city of Bengaluru. The primary surveyed data were analyzed using the Structural Equation Modeling (SEM) approach through AMOS 26. The research used the UTAUT 2 model to measure the usage and adoption of Artificial Intelligence (AI) among the employees of small and medium-scale food processing industries. -
A Study on Work Engagement among the School Teachers
Work engagement is a measurable degree of an persons positive or negative emotional attachment to their job, colleagues and organization which profoundly influences their willingness to learn and perform at work. Now a days it is observed that the commitment and dedication of the teachers in their profession as decreasing. It is also seen that teacher turnover is also becoming high. Even though the teachers in the schools were paid good, the turn over seems to be increasing. The study here tries to investigate the relationship with the work engagement and the socio demographic characteristics of teachers where the demographic variables could explain the relationship between the dimensions of work engagement. Descriptive research design is being used in the study . This design is helpful to identify the socio demographic characteristics and its relationship between the Work engagement among School teachers . The sample consisted of 100 school teachers who having more than one years of experience and the sample was selected by using the convenient sampling method. The study was done using the UWES Scale developed by Wilmar Schaufeli and Arnold Bakker in 2003 and nineteen other questionnaires were developed to know the other factors contributing to work engagement. The resourceful work environment can foster teachers work engagement. Consequently, the study shows that the older experienced married teachers shows the high level of work engagement where the educational qualification has no much role in it. This means that the young generation is not much interested in the profession with a a passion rather than they themselves consider it as a job. The work engagement can be increased among them through making interventions like improving and enhancing effective job and personal resources. -

Influence of positive psychological capacities emotional intelligence and subjective well being of nurses in healthcare sector
The aim of this research is to address the insufficient empirical investigation of newlinepositive psychological variables among the nurses in the healthcare sector in India. Here we explore positive psychological capacities proposed by Luthan and team 2007), newlinecomprising of self-efficacy, hope, optimism and resilience their influence on emotional newlineintelligence; a concept of empirical interest among the nursing population (Freshwater newlineand Stickley 2004) and subjective well-being. Gill (2011) has mentioned that the health newlineworker determines the quality and nature of services offered in any healthcare system. newlineAdhering to the conceptual framework of positive psychology, psychological capital, newlineconservation of resource and broaden-and-build theory, this study is an exploration of newline(a) the positive psychological capacities, (b) its influence on emotional intelligence, and (c) subjective well-being of nurses (n=302) across government, private and trust newlinehospitals in Bangalore. The hospitals were chosen based on stratified sampling with the nursing respondents identified through random sampling and judgemental sampling. A pilot newlinestudy was carried out (n=100) to validate the standardized scales used for measuring the newlinevariables. An explanatory sequential mixed method design was proposed through which newlinethe quantitative analysis using a detailed descriptive statistics and regression analysis suggested that efficacy, hope, optimism and resilience influenced emotional newlineintelligence. While resilience and optimism influenced subjective well-being of nurses newlinethere was no influence of emotional intelligence, self-efficacy and hope. A qualitative follow-up interview was executed (n=15) to understand the reason for no influence. The findings substantiated that most of the nurses viewed themselves as happy individuals despite their work-related dissatisfactions as almost all saw their profession as service to mankind. The implications of these findings are traced along with the suggestions for future research. -

A study on the prospects of zimbabwe fertilizer industry for a sustainable market match
This paper is as a result of a process of seeking a solution to theperennial challenge of mismatch of fertilizer demand and supply in Zimbabwe. The study investigated the causes of the mismatch of fertilizer demand and supply in the post agrarian reform with a view to finding the factors that cause the mismatch. The study has been necessitated by the fact that Zimbabwe?s economy is agro-based and supportsmore than twelve million people. The study was informed by the following objectives: (i) To know and understand the existing demand and supply of fertilizer in Zimbabwe(ii) To find reasons for the gap in the market and its impact on Zimbabwe?s agricultural sector (iii) To examine the role of banks and financial institutions in leveraging farmer access to loans in Zimbabwe (iv) To understand the farmers' perceptions of the situation and make justifications of the mismatch and (v) To suggest and adopt suitable strategies which reinforce sustainable demand and supply of fertilizer in the country. In context and pursuit of the objectives, this study used both qualitative and quantitative methodologies. A survey questionnaire was administered on the total of 380 respondents within the study returned questionnaires. The study was premised on 3 null hypotheses, one testing significance difference between product brand and market demand for fertilizer, another testing significance difference between availability and accessibility of fertilizer and yet another tested significance difference in the perception among farmers and stakeholders on the use of fertilizer. To do the hypothesis testing,data frequencies were run to note descriptive data patterns, cross-tabulations to establish a relationship between variable through various statistical tests: chi- square, correlations, ANOVA correlation coefficients, regression analysis and R-square value. Regression analysis was conducted to establish squared multiple correlation coefficient(R2) between Fertilizer Market,the unobserved dependent variable comprised of Demand (need for fertilizer, Supply/usage of fertilizer and availability of fertilizer) and independent composite variables of location/place of the fertilizer, fertilizer company brands, i.e. products, respondents in the study(people) and costs of financing fertilizer.This study accepted the first 2 null hypotheses and rejected the last hypothesis respectively.During the content thematic analysis salient themes and issues were; fertilizer availability at specific locations, high usage of ammonia brand, low application of fertilizer, inadequate fertilizer storage facilities, quality of fertilizer and accessibility to markets and specific fertilizers brands at specific periods. Upon triangulation, thequalitative responses were similar and complimentary to the quantitative responses.The composite or unobserved predictor variables; Place/Location of fertilizer, Type of fertilizer/Product brand, cost price and people accounted for the squared multiple correlation coefficient.573 or 57.3% (R2) adjusted R2 0.568 of the variance of Fertilizer Market dependent composite variable. This proportion in other words was the contribution of the independent variables. This suggests relationships that has the moderate effect (substantial) on Market the dependent variable based on the criterion that 0.573 is moderate. Regression analysis pointed to a strong Pearson correlations relation between fertilizer market and location (place where fertilizer was available) .004 and product 0.21. The unobserved predictor independent variable fertilizer type product or brand multiple correlation coefficient.517 or 51.3% (R2), fertilizer location or location could be found .542 or 54.2% (R2) with unobserved predictor dependent variable fertilizer market.Following onto this, the study highlights a model to help us better manage the mismatch. This model is developed from a collaborative ramework.The thesis ultimately makes conclusions and recommendations about crafting policies that will assist to match fertilizer demand and supply in Zimbabwe. -

Spectroscopic Study Of Selected Be Stars In Our Galaxy
The optical spectroscopic monitoring observation of two Be stars namely 4 Hercules and 88 Hercules was observed with 1.02m telescope at the VBO, Tamil Nadu, India over a period of six months. The spectra were reduced using standard routines in IRAF. The equivalent width of the lines were identified have been measured. The line profile variability exhibited by H? H?and HeI lines are studied to understand the emission mechanism in the Classical Be-stars. The properties of the process can be well constrained, leaving only few options, most importantly, but not exclusively, non-radial pulsation and small scale magnetic fields. In different stars different processes may be acting. This is not only true for the disk structure, but as well for its variability, both cyclic and secular. Be stars, at lower metallicities, seem more common and more rapidly rotating. The Be phenomenon, linked with one or more mass ejection processes, acts on top of a rotation rate of about 75% of critical or above. In this work, first the definition of Be-stars is contrasted to similar classes, and common observables obtaind for Be-stars are introduced and the respective formation mechanism explained. The current state of knowledge concerning the central stars as non-radially pulsating objects and non-magnetic stars, as far as it concerns large scale. The weak magnetic fields remain possible, but are of yet unproven. In this dissertation Chapter 1 discusses the features of Be- stars and reviewed the progress made in understanding Be-stars in the recent past. Chapter 2 discusses the literature review. Chapter 3 describes the methodology carried out to study the objective. Chapter 4 explains the result and analysis part of the research. Chapter 5 is about the conclusions. -

Convective Instability of Ferromagnetic Fluids in A Porous Medium
The thesis is concerned with the study of Rayleigh-Bard ferroconvection in a horizontal porous layer. Darcy-Brinkman law is employed to describe the fluid motion. The effect of second sound,thermal radiation, internal heat generation, variable viscosity and surface tension on the onset of Darcy-Brinkman ferroconvection is considered. newlineThe findings of the problems investigated in the thesis have implications for heat transfer applications wherein magnetic fluids serve as working media. The summary of the problems addressed in the thesis is given newlinebelow. Ferroconvection in a horizontal layer of porous medium with second sound The problem of Rayleigh-Bard convection in a ferromagnetic fluid saturated porous medium with the Maxwell-Cattaneo law is studied by newlinethe method of small perturbation. Modified Darcy-Brinkman model is used to describe the fluid motion. The horizontal porous layer is cooled from the upper boundary, while an isothermal boundary condition is imposed at the lower boundary. The fluid and solid matrix are assumed to be in local thermal equilibrium. The non-classical Maxwell-Cattaneo heat flux law involves a wave type heat transport and does not suffer from the newlinephysically unacceptable drawback of infinite heat propagation speed. The resulting eigenvalue problem is solved exactly for simplified boundary conditions and closed form solutions for both stationary and oscillatory instability are obtained. Some of the known cases have been deduced as newlinelimiting cases of the present study. The influence of porous, magnetic, and non-magnetic parameters on the onset of ferroconvection has been analyzed. It is found that magnetic stresses and second sound hasten the onset of Darcy-Brinkman ferroconvection. As the magnetic equation of newlinestate becomes more and more nonlinear, ferroconvection in a porous layer in the presence of second sound is advanced. However, it is delayed when the porous parameters are increased. -

Effect of Various Double-Frequency Modulations on Rayleigh-Benard Convection
Rayleigh-Bard convection in Newtonian fluid under different types of modulations are studied in this thesis by replacing the single frequency modulations with two frequency modulations with different amplitude and frequency. Linear and non-linear analysis of Rayleigh-Benard convection is considered under two-frequency gravity, rotation, temperature, magnetic field and internal heat generation modulation. The sixteen combinations of sinusoidal (trigonometric sine) and non-sinusoidal (square, triangular, sawtooth) wave forms of different modulations are considered to study the impact of modulations on the onset of convection and heat transport. The expressions for unmodulated Rayleigh number and correction Rayleigh number in the linear case are obtained from linearized Lorentz model using Venezian approach. To study the impact of different types of modulations and wave forms on the heat transport, the expression for the Nusselt number is obtained by solving the non-linear Lorentz model numerically. From the study it is found that the two-frequency modulations make the system more stable compare to no-modulation and single-frequency modulations. The mixing angle of the two frequency plays major role in deciding the stability of the system. The results pertaining to no-modulation and single frequency are obtained as the limiting cases. Onset of Rayleigh-Bard Convection and Heat Transfer under Two-frequency newlineRotation Modulation The study investigates the effect of sixteen sinusoidal (sine) and non-sinusoidal combinations (square, triangular, sawtooth) of time-periodic Coriolis force (rotation modulation) on Rayleigh-Bard convection (RBC) in a Newtonian liquid. The consideration captures the potential effects of two-frequency rotation modulation on stability, newlinespecifically the onset of convection and the amount of heat transfer in the system simultaneously. -

Attitude towards the medical profession among higher secondary students in relation to medical aptitude, parental influence, peer influence and perceived social expectations
Attitude towards the Medical Profession includes concepts, motives or beliefs associated with the profession of medical science. Medical science is a profession that challenges the intellectual competency of the aspirant owing to the strenuous demands of the career. It is essential that possession of an appropriate attitude and a realistic understanding of the demands of medical science be a pre-requisite, especially if the higher secondary adolescent aspires this as his or her vocation for life. As theformation of attitude is based on several intrinsic and extrinsic factors, a profession like medical science faces stiff competition among candidates to qualify with high expectations from family and society. The current study throws light on the attitude of higher secondary students towards the profession of medical science in relation to medical aptitude, parental influence, peer influence and perceived social expectations, as the independent variables. It aimed to explore the role played by medical aptitude, parental influence, peer influence and perceived social expectations in the formation of attitude towards the medical profession and the differences in the formation of this attitude among higher secondary students based on their gender and type of pre-university college that they belonged to. The study adopted was a descriptive study-cum-survey that employed a quantitative approach using the paradigm of post-positivism. The participants for the study comprised of 396 second-year higher secondary students from pre-university colleges of Bangalore South, who were
selected by convenience sampling method.
