Effects of chemical reaction and partial slip on the three-dimensional flow of a nanofluid impinging on an exponentially stretching surface
The three-dimensional mixed convection boundary layer flow of a nanofluid induced by an exponentially stretching sheet is numerically investigated in the presence of thermal radiation, heat source/sink and first-order chemical reaction effects. The adopted nanofluid model incorporates the effects of Brownian motion and thermophoresis into the mathematical model. The first-order velocity slip boundary conditions are also taken into account. The governing boundary layer equations are transformed into a set of nonlinear ordinary differential equations by employing suitable similarity variables. The resultant equations are solved numerically using the Runge-Kutta-Fehlberg method. Obtained solutions are compared with previous results in a limiting sense from the literature, demonstrating an excellent agreement. To show the typical trend of the solutions, a parametric study is conducted. The axial velocity, transverse velocity, temperature and nanoparticle volume fraction profiles as well as the skin-friction coefficient, Nusselt and Sherwood numbers are demonstrated graphically as a representative set of numerical results and discussed comprehensively. 2017, SocietItaliana di Fisica and Springer-Verlag Berlin Heidelberg. -

Effects of central bank intervention through quasi fiscal policies evidence from reserve bank of zimbabwe
This was a research exercise which was conducted to establish the impact of newlineZimbabwe s Central Bank s interventions on the economy. As Zimbabwe s economic newlinecondition went through a nose-dive, the government found itself unable to respond to newlinethe numerous needs with no resources. The country was achieving negative gross domestic product (GDP) growth rate every year since the turn of the new millennium. The country could not borrow from the Bretton Woods institutions such as the International Monetary Fund (IMF) because of the illegal sanctions imposed by the United States and European Union following the country s land reform program which acquired farms from the majority of the 4,000 white farmers who owned about 80 percent of the country s arable area. The Zimbabwe Economic and Democracy newlineRecovery Act of 2001 (ZEDERA), enacted in the USA prevented American companies from doing business in Zimbabwe. The Reserve Bank of Zimbabwe stepped in to assist. The research was aimed at establishing the effect the central bank intervention on the economy. Was the effect of the intervention good, or bad? Did the central bank s intervention really make things worse or did it ameliorate the effects of the downturn in the economy? For newlineinstance, did it contribute to the increase in inflation? What would have been the newlinesituation had the Bank not intervened? This study sought to answer the basic question: newline What was the overall impact of the RBZ s quasi-fiscal activities on the Zimbabwean newlineeconomy? Hypotheses were formulated on the basis of the above objectives and were tested newlinevia a variety of statistical techniques. The research instruments for data collection newlinewere a questionnaire and interviews guides. The questionnaire was the main research newlineinstrument followed by interviews. The questionnaire had a fusion of open ended and newlineclosed questions. The research showed that the RBZ s quasi-fiscal operations helped newlinethe country most in containing emergency situations and improved access to financial newlineresources by the productive sectors. -
Effects of bio-flocculated algae on the growth, digestive enzyme activity and microflora of freshwater fish Catla catla (Hamilton 1922)
In numerous ways, diets incorporating probiotics are beneficial to host animals. This study was conducted to evaluate the influence of bio-flocculated freshwater algae Chlorella vulgaris on the freshwater fish Catla catla. For the process of flocculating algae, probiotics Lactobacillus acidophilus (10307 MTCC) and Bacillus subtilis (MTCC 441) were used. The experimental fish were fed with Artemia franciscana enriched with flocculated algae for 60days. A control group was fed with unenriched A. franciscana. After the experimental period, there was a significant decrease in anaerobic bacteria and a significant colonization of candidate probiotics in guts of fish fed with flocculated algae-enriched Artemia. This treatment group also had a better growth performance with a higher average body length and weight (8.70.3cm, 5.830.9g) and survival % (981.02). High protease (7.8mg/protein?1) and lipase (2.56 mg/protein?1) activity were also found in the enriched A. franciscana-fed fish group. Comparatively, higher protein, lipid and PUFA/HUFA contents were also reported in this treatment group. The study found that flocculated algae-enriched A. franciscana has a positive impact on gut microflora, growth parameters and survival as compared to the unenriched group, and hence, the flocculated algae serve a dual purpose in rearing of C. catla. This study supports the inference that a bio-flocculated algae-incorporated diet is a preferable method for larval rearing aquaculture. 2020 John Wiley & Sons Ltd -
Effects of aggregation on TiO2ethylene glycol nanoliquid over an inclined cylinder with exponential space-based heat source: sensitivity analysis
The current study investigates the impact of nanoparticle (NP) aggregation on nanoliquid flow over an inclined elongating cylinder with an exponential space-related heat source. The dynamic viscosity and thermal conductivity for aggregation structure are modeled by utilizing the Modified Krieger-Dougherty Model and Bruggeman Model correspondingly. The governing equations are solved numerically. Further, the regression model for friction coefficient and heat transport rate is obtained by utilizing the Response Surface Methodology for various space-based heat source parameter (0.5 ? QE? 1.5), mixed convection parameter (1 ? ?? 3) and NPs volume fraction (0.01 ? ?? 0.05). The velocity profile exhibited dual features for different values of curvature parameter and NPs volume fraction. The space-based exponential heat source and mixed convection have an enhancing impact on the skin friction coefficient. It is noticed that the heat transport augments with the addition of nanoparticles. The coefficient of friction is found to be more sensitive to the NPs volume fraction. Further, the heat transport rate is more sensitive toward exponential heat source than NPs volume fraction and mixed convection. 2021, Akadiai Kiad Budapest, Hungary. -
Effects of activation energy and chemical reaction on unsteady MHD dissipative DarcyForchheimer squeezed flow of Casson fluid over horizontal channel
The impact of chemical reaction and activation energy plays a vital role in the analysis of fluid dynamics and its thermal properties. The application of the flow of fluid is significantly considered in nuclear reactors, automobiles, manufacturing setups, electronic appliances etc. This study explores the impacts of activation energy and chemical reaction on the magnetohydrodynamic DarcyForchheimer squeezed Casson fluid flow through a porous material across the horizontal channel where the two parallel plates are assumed to be in motion. By using similarity variables, partial differential equations are converted to ordinary differential equations. Numerical method is applied using MATLAB to solve the problems and acquire the data for velocity field, thermal distribution, and concentration distribution. The graphs indicate that fluid velocity and temperature increases as the plates are brought closer. In addition, there was a correlation between a rise in the Hartmann number and a decrease in the fluid's velocity because of the existence of strong Lorentz forces. The temperature and the concentration of the liquid will increase due to the Brownian motion. When the DarcyForchheimer and activation energy parameters are both increased, the velocity and concentration decreases. 2023, The Author(s). -
Effects of a Mindfulness-based Intervention on Well-being Among Rural Adolescents with Academic Anxiety
Background: Academic anxiety revolves around scholastic work and performance and can be detrimental to students health and overall subjective well-being. It has been found to be significantly high in adolescents, leading to consequences that prove to be detrimental to their academic performance, focus, and overall self-esteem. This phenomenon acts as a vicious cycle impacting all aspects of a students life. Method: The current study aimed to explore mindfulness-based intervention (MBI) as a possible option to deal with academic anxiety in rural adolescent students and improve their overall subjective well-being. A total of 600 students were screened for academic anxiety and a total of 47 students were subjected to an eight-week MBI. MBI aims to bring more present-moment awareness and cultivate overall well-being and thereby works against anxiety. Mixed repeated measures ANOVA was carried out to compare pre, post, and follow-up scores. Result: The results indicated a significant effect of MBI on adolescents, suggesting a significant decline in academic anxiety from pre-to-post and an increase in mindfulness and subjective well-being from pre-to-post and follow-up assessments. Conclusion: Academic anxiety and subjective well-being improved significantly with the MBI intervention, thereby implication that MBI is a feasible option for rural adolescents with academic anxiety. 2024 The Author(s). -
Effects of 12 Weeks Core Strength Training on Bio-motor Fitness Abilities among College Level Soccer Players
This study aimed to evaluate the effects of a 12-week core strength training (CST) program on bio-motor fitness components among college-level male soccer players aged 18 to 23 years. Methods: Sixteen male soccer players participated in this study. They were divided into an experimental group that underwent a CST program and a control group that maintained their regular training routine. The CST program, integrated into the regular soccer training schedule, included exercises such as planks, bridges, and various forms of crunches, progressively increasing in intensity. Upper body explosive strength was assessed using a backward medicine ball throw, lower body explosive power using a standing long jump and countermovement jump, and change of direction speed using an agility test. Sprint performance was measured with 15m and 30m linear sprint tests. Results: The CST group showed significant improvements across all measured variables. Notable percentage changes were observed in the 15m sprint (4.08%), 30m sprint (1.56%), upper body strength (6.87%), standing long jump (4.66%), countermovement jump (15.69%), and change of direction speed (12.35%). Effect sizes indicated substantial enhancements in standing long jump (g = 1.634, p = 0.001), countermovement jump (g = 7.110, p < 0.001), and change of direction speed (g = 3.142, p = 0.001). The control group did not exhibit significant changes in any variables. Conclusion: A 12-week core strength training program, consisting of three sessions per week, significantly improved bio-motor fitness components in college-level soccer players aged 18 to 23 years. These findings support the inclusion of CST in soccer training regimens to enhance athletic performance. 2024 by authors, all rights reserved. -

Effectiveness of social advertisements on attitudes & practices
Social Advertisements is an influential device for social change. Social advertising is a process of changes in the behaviour is to be positive for promoting social issues through marketing and advertising principles From Social advertising change in behaviour to the individual targeted groups, make them to accept with a behaviour of new-fangled, discard a old behaviour, amend a present behaviour. Social advertising intends to confines targeted customers who wants to change, mutate or reject certain practices such as smoking, drinking, etc. and stimulate them to carry out socially desirable actions. We can see that organizations like UNICEF, UNESCO have used Social advertising for various purposes and with various degrees of success all across the world. Social Advertising and marketing is increasingly common in UK, USA, Australia, Canada and Scandinavian countries, where fundraising and collaboration between companies and NGOs happen almost every day. In a country like India which is faced with a multitude of problems we can reap huge benefits from the proper usage of social advertisements. Attitude and practices are interlinked. Actions are based on thoughts, Practices are based on Attitudes, The people who are having favourable attitudes and they are having favourable practices. The consequences of both primary & secondary data are related to each other which determine that the attitude and practices are interweaved to each other. Therefore the study deduces that there is association between the attitude and practices of health and hygiene. A sample size of 275 was considered and stratified random sampling technique was adopted for this uni-dimensional study which has been carried out with emphasis upon three major demographic variables?District, Area and Gender. Considering these variables as strata, a sample was collected from the respondents belonging to the different established strata in the form of questionnaires. Questionnaires were developed in consultation with experts which are having high reliability scores. After the collection of data, the data was subjected to both descriptive and inferential statistical analysis based on the hypotheses formulated using SPSS (version 22.0). The inference of the study was that people who were regularly exposed to social advertisements gained a high level of awareness about health &hygiene, and developed favourable attitude and practices through attitude and practices.

EFFECTIVENESS OF SERVICE QUALITY IN MULTISPECIALITY AND SINGLESPECIALITY HOSPITALS-A COMPARATIVE STUDY
The growth in the health care services in the country is primarily driven by the 350 million strong middle class people aspiring for quality health care services. A health care provider is an institution (such as a hospital or clinic) or person (such as a physician, nurse, other health care service provider) that provides preventive, curative, rehabilitative or palliative care services in a systematic way to individuals, families or communities. Improving access, coverage and quality of health services depends on the way, the services are organized and managed, and on the incentives influencing providers and users. The rate of growth of the health care industry in India is moving ahead neck to neck with the pharmaceutical industry and the software industry of the country. Much has been said and done in the health care sector for bringing about improvement. Till date, approximately 12% of the scope offered by the health care industry in India has been tapped. The health care industry in India is reckoned to be the engine of the economy in the years to come. Health care industry in India is worth $17 billion and is anticipated to grow by 13% every year. The health care sector encompasses health care instruments, health care in the retail market, hospitals enrolled to the hospital networks etc. Literature review on Service quality in the hospitals has mostly emphasized on patients perception of the services, the factors responsible for creating customer satisfaction and their intentions to return for future services available. The literature also reveals the gap between customer expectations and customer perception. The findings of the literature identifies the future courses of action to be taken by the hospitals. The loyalty is created in the hospitals by service quality dimensions. The literature so far shows the research in Hospitals; the research gap is that no research has been done in the sectors like Multispeciality Hospitals and Singlespeciality Hospitals. Statement of the problem: Effectiveness of service quality in Multispeciality and Singlespeciality Hospitals- A comparative study The population for the study consists of the patients from both the sectors. The Questionnaire were administered to 315 respondents out of which 292 were the usable data for analysis. The sampling technique adopted was Convenience sampling. The sample was drawn from 6 multispeciality hospitals and 5 single speciality hospitals in Bangalore city only. The Questionnaire consisted of three sections; the first section on the Demographic characteristics, Section 2 consists of the service quality dimensions for expectations and perception. The dimensions were rated on 7 point Likert scale. The third section on the customer loyalty. The patients of the hospitals have rated independently without any bias. The developed questionnaire was found to be very reliable and valid. Conclusion:The present research found that the service quality is high in Multispeciality hospitals when compared to single speciality hospitals. The Reliability dimension is very important when compared to the other dimension. Also the study revealed that price is the very sensitive variable that the customer loyalty depends on the price justification. Hence the research throws light upon the Servqual and the customer loyalty. -
Effectiveness of public policy in reviving the COVID-19 hit economy: Evidences from Kerala, India
The economic crisis triggered by the COVID-19 urgently required active policy interventions to enhance the revival strategies of the world economy. This paper examines the effectiveness of policy intervention of the State Government of Kerala in India in mitigating the risks caused by the pandemic. The policy effectiveness is evaluated by analyzing the data collected from a sample of 300 beneficiaries with the help of descriptive statistics, ordered probit (OP) model, and semi nonparametric extended OP (SNEOP) model. Our results are assertive with the fact that state policies are effective in reviving the crisis-hit economy as they have primarily helped low-income groups and other marginalized communities. The majority of BPL families, self-help group members, and social security beneficiaries rated government policies as highly or fairly effective. Though the policies are found to be highly effective among those who have suffered income loss, the study does not find sufficient evidence to believe that the government interventions are effective in helping those who have lost their jobs. The level of effectiveness is inversely related to age, education, and family size. Our results suggest that an extensive fiscal package is required to help people recover from the crisis. 2021 John Wiley & Sons Ltd. -
