Entropy generation analysis of magneto-nanoliquids embedded with aluminium and titanium alloy nanoparticles in microchannel with partial slips and convective conditions
Alloy nanoparticles; Convective condition; Joule heating; Microchannel; Nanofluid; Slip flow
Purpose: Outstanding features such as superior electrical conductivity and thermal conductivity of alloy nanoparticles with working fluids make them ideal materials to be used as coolants in microelectromechanical systems (MEMSs). This paper aims to investigate the effects of different alloy nanoparticles such as AA7075 and Ti6Al4V on microchannel flow of magneto-nanoliquids with partial slip and convective boundary conditions. Flow features are explored with the effects of magnetism and nanoparticle shape. Heat transport of fluid includes radiative heat, internal heat source/sink, viscous and Joule heating phenomena. Design/methodology/approach: Suitable dimensionless variables are used to reduce dimensional governing equations into dimensionless ordinary differential equations. The relevant dimensionless ordinary differential systems are computed numerically by using RungeKuttaFehlberg-based shooting approach. Pertinent results of velocity, temperature, entropy number and Bejan number for assorted values of physical parameters are comprehensively discussed. Also, a closed-form solution is obtained for momentum equation for a particular case. Analytical results agree perfectly with numerical results. Findings: It is established that the entropy production can be improved with radiative heat, Joule heating, convective heating and viscous dissipation aspects. The entropy production is higher in the case of Ti6Al4V-H2O nanofluid than AA7075-H2O. Further, the inequality Ns(?)Sphere > Ns(?)Hexahedran > Ns(?)Tetrahydran > Ns(?)Column > Ns(?)Lamina holds true. Originality/value: Effects of aluminium and titanium alloy nanoparticles in microchannel flows by using viscous dissipation and Joule heating are investigated for the first time. Flow features are explored with the effects of magnetism and nanoparticle shape. The results for different alloy nanoparticles such as AA7075 and Ti6Al4V have been compared. 2019, Emerald Publishing Limited.

Genuine handwriting variations in 10 years: a pilot study
Forensic Document Examination; Forensic science; Genuine handwriting; Variations in handwriting characteristics
Background: The present study aims to examine the extent of variation in genuine handwriting characteristics across 10years. One hundred samples (one admitted handwriting and three exemplars) were collected from 25 subjects (male and female, age ranging from 30 to 55) using purposive sampling technique. The admitted handwriting sample included documents like notebooks, wills, diaries, and record books that had been written 10years earlier, and 3 exemplars with the same information, written now in a similar kind of material. Both individual and class characteristics were analyzed in admitted as well as three exemplars which includes size of letters, slant, i-dot, t-bar (diacritics), humped letters (m, n, h), and formation of rounded letters (o, a, d, b, g, p, q). Results: Cohens kappa showed that there is a significant agreement between admitted and exemplars in the characteristics except for size. Conclusion: The results imply that once an adult has acquired a particular handwriting pattern, the master pattern of each letter, as well as both class and individual characteristics, remain unchanged. The size of the letters may change across age. 2019, The Author(s).

Star-forming, rotating spheroidal galaxies in the GAMA and SAMI surveys
Galaxies: Dwarf; Galaxies: Fundamental parameters; Galaxies: Structure; Surveys
The Galaxy And Mass Assembly (GAMA) survey has morphologically identified a class of 'Little Blue Spheroid' (LBS) galaxies whose relationship to other classes of galaxies we now examine in detail. Considering a sample of 868 LBSs, we find that such galaxies display similar but not identical colours, specific star formation rates, stellar population ages, massto- light ratios, and metallicities to Sd-Irr galaxies. We also find that LBSs typically occupy environments of even lower density than those of Sd-Irr galaxies, where ?65 per cent of LBS galaxies live in isolation. Using deep, high-resolution imaging from VST KiDS and the new Bayesian, 2D galaxy profile modelling code PROFIT, we further examine the detailed structure of LBSs and find that their Ssic indices, sizes, and axial ratios are compatible with those of low-mass elliptical galaxies. We then examine SAMI Galaxy survey integral field emission line kinematics for a subset of 62 LBSs and find that the majority (42) of these galaxies display ordered rotation with the remainder displaying disturbed/non-ordered dynamics. Finally, we consider potential evolutionary scenarios for a population with this unusual combination of properties, concluding that LBSs are likely formed by a mixture of merger and accretion processes still recently active in low-redshift dwarf populations.We also infer that if LBS-like galaxies were subjected to quenching in a rich environment, they would plausibly resemble cluster dwarf ellipticals. 2019 The Author(s).

Biogenic synthesis of g-C3N4/Bi2O3 heterojunction with enhanced photocatalytic activity and statistical optimization of reaction parameters
Bismuth oxide; Box-Behnken design; Eichhornia crassipes; g-C3N4 ; Malachite green; Photocatalyst
A facile and efficient biogenic method was adopted to synthesize Bi2O3 and g-C3N4/Bi2O3 nanocomposites using Eichhornia crassipes plant extract. These composites were characterized by various analytical tools such as XRD, FTIR, SEM, TEM and UV-DRS. Bismuth oxide and g-C3N4/Bi2O3 show varied optical and photocatalytic properties due to the differences in their band gap. Here, Box-Behnken design (BBD) combined with Response Surface Methodology (RSM) has been used to optimize the coupled effect of independent parameters for the dye degradation. The synthesized g-C3N4/Bi2O3 nanocomposite exhibit excellent photocatalytic activity for the degradation of malachite green (MG) dye. Total Organic Carbon (TOC) analysis unveiled 78% photomineralization of MG over g-C3N4/Bi2O3 in 5 h. The p-n junction of g-C3N4/Bi2O3 with better oxidative ability and effective charge separation is the primary reason for its improved photocatalytic activity. The modified photocatalyst shows satisfactory catalytic activity and reusability towards photodegradation of common water pollutant MG up to 4 cycles. They offer great potential in the field of photocatalysis due to their superior efficiency and applications in environmental remediation. 2019 Elsevier B.V.

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.

A study of entrepreneurial choices and challenges encountered by young graduates
Challenges; Entrepreneurs; Young graduates
India, one of the most populous countries is growing phenomenally, though the challenges of unemployment is compounding. An unique method of overcoming this issue is through motivation of college students in becoming entrepreneurs, which will not only create employment but will also reduce the pressure of gaining employment on the students. However, flexible government policies in favor of entrepreneurs will facilitate the economic development of the country. In this study, a quantitative method is used to collect the data on entrepreneurship and the changing preferences of college students. A survey (N= 209) among college students of Bengaluru, India is conducted to identify the impact of entrepreneurship on work life choices of young graduates, evaluate the emergence of entrepreneurs in influencing decisions and analyzing the differing choices of males and females in terms of entrepreneurial selections. Analysis of the collected data indicates that Indian Government policy, unskilled labor, entrepreneurial education, family background and caste are factors affecting the entrepreneurial growth rate in Bangalore. Entrepreneurship education in Bangalore is still in the early stages, thus, depriving the college students from acquiring gainful practical knowledge. The structure of a conventional learning system and lack of social experiences also affects the learning process. 2019, International Journal of Scientific and Technology Research.

GASP XXIII: A Jellyfish Galaxy as an Astrophysical Laboratory of the Baryonic Cycle
With MUSE, Chandra, VLA, ALMA, and UVIT data from the GASP program, we study the multiphase baryonic components in a jellyfish galaxy (JW100) with a stellar mass 3.2 1011 M o hosting an active galactic nucleus (AGN). We present its spectacular extraplanar tails of ionized and molecular gas, UV stellar light, and X-ray and radio continuum emission. This galaxy represents an excellent laboratory to study the interplay between different gas phases and star formation and the influence of gas stripping, gas heating, and AGNs. We analyze the physical origin of the emission at different wavelengths in the tail, in particular in situ star formation (related to H?, CO, and UV emission), synchrotron emission from relativistic electrons (producing the radio continuum), and heating of the stripped interstellar medium (ISM; responsible for the X-ray emission). We show the similarities and differences of the spatial distributions of ionized gas, molecular gas, and UV light and argue that the mismatch on small scales (1 kpc) is due to different stages of the star formation process. We present the relation H?-X-ray surface brightness, which is steeper for star-forming regions than for diffuse ionized gas regions with a high [O i]/H? ratio. We propose that ISM heating due to interaction with the intracluster medium (either for mixing, thermal conduction, or shocks) is responsible for the X-ray tail, observed [O i] excess, and lack of star formation in the northern part of the tail. We also report the tentative discovery in the tail of the most distant (and among the brightest) currently known ULX, a pointlike ultraluminous X-ray source commonly originating in a binary stellar system powered by either an intermediate-mass black hole or a magnetized neutron star. 2019.

Benzimidazole and benzothiazole fluorophores with large Stokes shift and intense sky-blue emission in aggregation as Al3+ and Pb2+ sensors
New fluorophores based on 2-(2?-hydroxyphenyl)benzimidazole (HBZ) and 2-(2?-hydroxyphenyl)benzothiazole (HBT) for metal ion sensing were designed and synthesized using a simple method. The photophysical behaviour of these fluorophores were investigated in various solvents using UVvisible and fluorescence spectra. All the heterocycles showed strong excited state intramolecular proton transfer (ESIPT) characteristics with remarkably large Stokes shift (190252 nm). Spatial charge distribution in the frontier molecular orbitals also demonstrated the ESIPT mechanism through intramolecular charge transfer. Time resolved fluorescence measurements for these heterocycles showed two long-life decay mechanisms which may be attributed to excited state enol and keto emission. These intense sky-blue emitters also exhibited aggregation induced blue shifted emissions due to restriction of intramolecular rotation processes. Fluorescence sensing studies for metal ions revealed the good selectivity of these fluorophores towards Al3+ and Pb2+. Theoretical computations performed using density functional theory methods showed two possible geometric configurations for Al3+ binding. 2019 Elsevier B.V.

Stock market prediction using subtractive clustering for a neuro fuzzy hybrid approach
ANFIS training method; Neuro fuzzy approach; Stock market prediction; Technical indicators
Stock market prediction is the challenging area for the investors to yield profits in the financial markets. The investors need to understand the financial markets which are more volatile and affected by many external factors. This paper proposes a subtractive clustering based adaptive neuro fuzzy approach for predicting apple stock data prices. The research data used in this study is from 3rd Jan 2005 to 30th Jan 2015. Four technical indicators are proposed in this study. They are Simple moving average for 1week, simple moving average for 2weeks, 14days Disparity and Larry Williams R%. These variables are used as inputs to the neuro fuzzy system to predict the daily apple stock prices. Also, this study compares the proposed work with the ANFIS training method and subtractive clustering method etc. The performance of all these models is analyzed. The measures like training error, testing error, number of rules and number of parameters are calculated and compared for analysis. From the simulation results, the average performance of subtractive clustering based neuro fuzzy approach was found considerably better than the other networks. 2017, Springer Science+Business Media, LLC.

Antiwear performance evaluation of halloysite nanotube (HNT) filled polymer nanocomposites
Glass-epoxy; Halloysite Nanotube (HNT); Nanocomposites; Specific wear rate; Vacuum bagging
Polymer nanocomposites containing various types of reinforcements and fillers are oftenly used in applications such as sliding elements in the machine and automotive parts, gear assemblies etc., in which tribological performance parameters viz. friction and wear are the major issues. In this work, the specific wear rate of HNT filler loading (0-4wt %) in Glass-Epoxy nanocomposites fabricated by vacuum bagging technique are evaluated experimentally. For this purpose, the specimens are prepared and tests are conducted as per the ASTM G-99 standard for a number of trials with the assistance of a pin-on-disc machine by varying load and speed values, keeping time and track diameter constant. The results obtained from experiments reveals that reduction in specific wear rate and the amount of material loss is quite significant for HNT loaded specimens when compared with neat sample even at higher operating conditions. This indicates that HNT comprises of hard ceramic elements viz. SiO2 and Al2O3 which eventually enhances the antiwear behaviour of prepared nanocomposites. Finally, a study on wear mechanisms and morphologies are carried out by analyzing the worn surfaces through SEM micrographs. BEIESP.

Optimized uplink scheduling model through novel feedback architecture for wimax network
Broadband Wireless Access has drawn the fine attention due to the wide range of data requirement and user mobility all the time. Moreover, WiMAX provides the best QoE (Quality of Experience) which is based on the IEEE 802.16 standards; this includes several services such as data, video and audio. However, in order to provide the effective and smooth experience i.e. QoS scheduling plays one of the critical part. In past several mechanism has been proposed for effective scheduling however, through the research it is observed that it can be furthermore improvised hence in this we propose a mechanism named as OUS (Optimized Uplink Scheduling) which helps in improvising the QoS. In here, we have proposed a novel feedback architecture and proposed optimized scheduling which helps in computing the bandwidth request this in terms helps in reducing the delay as well as jitter. Moreover, the performance evaluation is performed through extensive simulation by varying the different SS and frequency and the results analysis confirms that our mechanism performs way better than the existing algorithm.

Can menstrual cups become an alternative to sanitary napkins? A critical analysis among women in bangalore city
Environmental hazards; Menstrual cup; Menstruation; Personal hygiene; Sanitary napkin
The topic of menstrual hygiene is always considered as a taboo to speak out in the public and even women hesitate to discuss their feelings or experiences about the same. With the help of revolutionary product called Sanitary Napkins, many women were able to understand their menstrual pattern and maintain their personal hygiene effectively. However, there has been number of new products flooding the market that is eco-friendly as well as economical. One such product is Menstrual cups and this research paper primarily tries to understand the consumer awareness and the usage of menstrual cups as an alternative to sanitary napkins among women in Bangalore city. Since sanitary napkins result in generation of ample amount of wastes and possess the risk of health hazards like TSS,UTI and yeast infections; this research focuses on understanding how women are ready for adopting eco-friendly method like menstrual cups. To understand the same, a sample of 138 women respondents were taken for the study from different age groups, educational qualification and income groups and were asked to fill a questionnaire. Their perception on menstrual hygiene, menstrual cup awareness and its usage are recorded, analysed and interpreted with the help of SPSS. 2019, Indian Journal of Public Health Research and Development.

Comparative analysis of rural consumers purchase behavior towards mobile phone in Karnataka
Indian urban market is getting saturated for many products. Thus, due to success of brands like Chik shampoo, Project Shakti, LG, Dabur, HLL (then2005), many marketers are now expanding their product offerings to rural markets as well. Also, since major part of India living in villages (around 70%) are now more improved due to increased literacy, TV penetration and improved affordability is a reason for marketers to expand. Of the research conducted on rural India, majority was either on understanding rural consumers on price, quality, brand, function and style or comparing rural consumers over urban consumers on buying behavior. This research focused on comparing rural consumers of two different districts on age, brand and opinion leaders role on influencing the rural preference towards mobile phone. The research focused on understanding the buying behavior of two villages, Keelara and Alekere of Mandya and two villages, Araleri and medahatti of Kolar with reference to mobile phone. 2019 SERSC.

Toward knowledge societies in the gandhian perspective and the civil rights movement
African American; Civil Rights; Colonialism; Gandhi; India; King
Mohandas K Gandhi and Martin Luther King, Jr as disciples of nonviolence fought against oppression. Gandhi and King strove to learn beyond what their schools taught them and became better educated men. Gandhi had a vision and King a dream. Through education Gandhi helped those who had Kings dream to connect the dream with the vision to deal with the awful reality of injustice and helped to make the world a better place. This paper through the four Pillars of Learning will demonstrate how Gandhi impacted the Civil Rights Movement with his vision and how leaders of the Civil Rights Movement and King among them appropriated the vision of Gandhi and used nonviolence as a tool to deal with the oppression under which they lived. 2019 Journal of Dharma: Dharmaram Journal of Religions and Philosophies (DVK, Bangalore).

Hope; Journey; Purpose; Salvation; Sin; Spiritual quest; Truth
This research is a comparative study of the Journey of Santiago in 'The Alchemist' who is after a personal legend and Christian in 'The Pilgrim's Progress' who sets his journey to attain Salvation. The aim of the study is to understand the similarities and diff erences of the terms such as Spiritual Quest, Sin, Purpose of Life, Truth and Sin. The growth of the two journeys has been analysed by highlighting the similarities and differences between the two. Such comparison not only helps in better understanding but it also helps to find new insights. Through the observations one states that though material treasure brings happiness but it is momentarily but a journey of trusting God will bring better understanding of the world. IJSTR 2019.

Impact of domestic investment, market size, and trade openness on outward fdi: A panel data analysis on brics
BRICS; Domestic Investment; Market Size; Outward FDI; Panel Data; Trade Openness
The recent phenomenal increase in the outward foreign direct investment (FDI) of emerging countries has raised concerns among policymakers. One school of thought argues that when multinational firms relocate production facilities abroad, it reduces the likelihood of concurrent investments in the home country, resulting in reduced domestic output. In this case, the outward FDI would harm the domestic investments. The other argues that the outward FDI would be more advantageous for the domestic investment when firms internationalize for entering into new markets and/or to import intermediate goods, wherein outward investments boost the returns in the home country, leading to a positive impact of outward FDI on domestic investment. The influence of the outward FDI on the domestic investment of any country or a region state cannot be generalized as each country is unique, and the drivers of investments would differ for different countries at the different development phases of each country. An attempt was made in this study to empirically trace the impact of the domestic investment, market size, and trade openness of the BRICS's members on the BRICS's outward FDI as a group. The results of the panel least square method highlighted that the variables - domestic investment and trade openness of BRICS had a positive effect on the outward FDI; whereas, the market size of BRICS was inversely related to outward FDI of BRICS. The data were tested for stationarity and Hausman test validated the results. 2019, Associated Management Consultants Pvt. Ltd.. All rights reserved.

Role of mixed nanofluids on fluid flow and intensify energy transfer in a boundary layer region driven by a free convective force
free convection; hybrid nanofluids; numerical solutions; porous parameter; volume fraction
This research study explores boundary layer flow and intensification of heat transfer through a porous medium accompanied by buoyant forces with the support of appended mixed nanofluids. The generated partial differentiation model is altered to a couple of the highly complicated nonlinear differentiation model by support of the similarity conversion. The resultant model is then resolved by the shooting method for finding the initial approximation and thereafter the Runge-Kutta-Fehlberg 45th-order method is used to get the desired result. The energy transfer and the flow of mixed nanofluids are analyzed by considering vital factors, like convection, porous and volume fraction. The acquired results fairly agree with erstwhile published articles. The major finding is that for greater values of the volume fraction, both fluid flow and energy transfer of a mixed nanofluid will be greater when compared with a regular nanofluid. 2019 Wiley Periodicals, Inc.
