Published: June 2019

'Touch me not' plant is o herb that shows sensation on touch, which is taxonomically called as Mimosa pudica. The fern like leaves close up and droop when touched; usually re-open within few minutes as a response to stimuli. Mimosa pudica reacts to mechanical stimuli with help of mechanosensitive channels. They are ideal transducers of physiologically relevant mechanical forces. The present study focus on the effect of mechanical stimuli in terms of various touch viz., human, plastic, cotton, fiber and wood on the sensitivity of Mimosa pudico plant whose leaves are at tender stage. Time taken for the leaflets to close and reopen was noted for each of the above mentioned stimuli. The t-test has shown the significant result for various mechanical stimuli. The rote of sensitivity was very high in Mimosa pudica as result of plastic touch.

Performance Enhancement of Soap Via Multi Level Caching
Authors: Shukla Samiksha , Mishra D. K. , Tiwari Kapil
Published: June 2019

Due to complex infrastructure of web application response time for different service request by client requires significantly larger time. Simple Object Access Protocol (SOAP) is a recent and emerging technology in the field of web services, which aims at replacing traditional methods of remote communications. Basic aim of designing SOAP was to increase interoperability among broad range of programs and environment, SOAP allows applications from different languages, installed on different platforms to communicate with each other over the network. Web services demand security, high performance and extensibility. SOAP provides various benefits for interoperability but we need to pay price of performance degradation and security for that. This formulates SOAP a poor preference for high performance web services. In this paper we present a new approach by enabling multi-level caching at client side as well as server side. Reference describes implementation based on the Apache Java SOAP client, which gives radically enhanced performance.

Boundary Layer Flow of Ferrofluid over a Stretching Sheet in the presence of Heat Source/Sink
Authors: Abraham Annamma , Titus LS. Rani
Published: June 2019

The boundary layer flow of ferrofluid over a stretching sheet with heat source is considered. It is assumed that the magnetic field is sufficiently strong enough to saturate the ferrofluid and the variation of magnetization with temperature can be approximated by a linear function of temperature difference. The boundary layer approximation is used and the transformed governing differential equations are solved using the Shooting technique based on Runge - Kutta Fehlberg and Newton Raphson methods. The effects of various parameters on velocity profiles and wall heat transfer are presented graphically. The results have possible industrial applications in liquid based systems involving stretchable materials.

Published: June 2019

Ruthenium(III) and palladium(II) complexes of 2-methylbenzimidazole (Mebzlh) ligand encapsulated in the super cages of zeolite-Y and ZSM-5 have been synthesized and characterized by various physico-chemical measurements. A suitable reaction condition has been optimized for [Ru(Mebzlh)]-Y by considering the effect of various parameters such as different solvents, concentration of substrate, reaction time and amount of oxidant etc., for the maximum conversion of phenol to a mixture of catechol and hydroquinone. The results obtained showed that selectivity for the catechol formation is ca. 85%, even though the conversion of phenol varies in the order [Ru(Mebzlh)]-Y (35%) > [Pd(Mebzlh)]-Y (15 %) > [Ru(Mebzlh)]- ZSM-5(10 %) > [Pd(Mebzlh)]- ZSM-5 (2 %) after 6 h of reaction time.

Graphs in Network Flows
Authors: Manjula V
Published: June 2019

This paper presents a collection of basics and application of Network flows in Graph theory which is an out- growth of set of lecture notes on Graph applications. It is not only a record of material from text books but also a reflection of precise graphical concept which will be useful for students where such facts are needed. There are many real life problems dealing with discrete objects and binary relations and graph is very convenient form of its representation. A network flow graph G=(V,E) is a directed graph with two special vertices: the source vertex s, and the sink vertex t. Many problems in the real world are to be solved using maximum flow. "Real" networks, like the Internet or electronic circuit boards, are good examples of flow networks. Generally graphs can be used in two situations. Firstly since graph is a very simple, convenient and natural way of representing the relationship between objects. Secondly we have graph as model solve the appropriate graph theoretic problem then interpret the solution in terms of original problem In the modern world, planning efficient routes is essential for business and industry, The flow of information or water or gas etc in a network are useful to find the max rate of flow that is possible from one station to another A Transport network represents a general model for transportation of material from origin of supply to destination through shipping routes. The objective of this paper is to discuss the concepts and terminology of Network flows with Graphical representations.

Solvent Effect on Fluorescence Quenching of 7, 8 Benzo‑4‑azido Methyl Coumarin by Aniline
Authors: Melavanki R M , Patil N R , Nagaraja D , Patil H D , Kadadevarmath J S , Kusanur R A
Published: June 2019

Fluorescence quenching of biologically active studies of 7, 8 benzo-4-azidomethyl coumarin (7BAMC) by aniline in four different organic solvents namely benzene, dioxane, tetrahydrofuran and acetonitrile has been carried out at room temperature with a view to understand the quenching mechanisms. The Stern–Volmer (S-V) plot has been found to be non-linear with a positive deviation for all the solvents studied. In order to interpret these results we have invoked the ground state complex formation and sphere of action static quenching models. Using these models various quenching rate parameters have been determined. The magnitudes of these parameters suggest that sphere of action static quenching model agrees well with the experimental results. Hence the positive deviation is attributed to the static and dynamic quenching. Further, with the use of Finite Sink approximation model, it was possible to check these bimolecular reactions as diffusion-limited and to estimate independently distance parameter R’ and mutual diffusion coefficient D. Finally an effort has been made to correlate the values of R’ and D with the values of the encounter distance R and the mutual coefficient D determined using the Edward’s empirical relation and Stokes – Einstein relation.

Published: June 2019

Fluorescence quenching of 2-(4'-t-Butylphenyl)-5-(4"-biphenylyl)-1,3,4-oxadiazole (BPBD) by aniline in toluene has been carried out at room temperature by steady state and time resolved fluorescence spectroscopy. The Stern-Volmer plot by steady state method has been found to be non-linear showing a positive deviation, whereas by time-resolved method it is linear. In order to interpret these results we have used the ground state complex and sphere of action static quenching models. Using these models various rate parameters have been determined. Based on these models, with finite sink approximation model, we conclude that positive deviation Stern-Volmer plot is due to the simultaneous presence of dynamic and static quenching processes.

Authors: Pranesh S , Sameena Tarannum , Riya Baby
Published: June 2019

The effect of Suction – injection combination on the onset of Rayleigh – Bénard electroconvection micropolar fluid is investigated by making a linear stability analysis. The Rayleigh-Ritz technique is used to obtain the eigenvalues for different velocity and temperature boundary combinations. The influence of various parameters on the onset of convection has been analysed. It is found that the effect of Prandtl number on the stability of the system is dependent on the SIC being pro-gravity or anti-gravity. A similar Pe-sensitivity is found in respect of the critical wave number. It is observed that the fluid layer with suspended particles heated from below is more stable compared to the classical fluid layer without suspended particles.

Finally, the similar type of results for the maximal planar graphs are obtained.
Some Results on Rosa-type Labelings of Graphs
Authors: Rajarajachozhan R
Published: June 2019

Labelings that are used in graph decompositions are called Rosa-type labelings. The gamma-labeling of an almost-bipartite graph is a natural generalization of an alpha-labeling of a bipartite graph. It is known that if a bipartite graph G with m edges possesses an alpha-labeling or an almost-bipartite graph G with m edges possesses a gamma-labeling, then the complete graph K_{2mx+1} admits a cyclic G-decomposition. A variation of an alpha-labeling is introduced in this paper by allowing additional vertex labels and some conditions on edge labels and show that whenever a bipartite graph G admits such a labeling, then there exists a supergraph H of G such that H is almost-bipartite and H has a gamma-labeling.

Water - Borne Pathogens from Diffrent Sources of Jabalpur Region
Authors: Gupta Mahendra K.
Published: June 2019

Water-borne diseases constitute one of the major public hazards in developing countries(WHO 1997), in India, more than 70 % of the epidemic are either water-borne or water related( Khera et.al.1996). The pathogens most frequently transmitted through water are those which cause infection of the intestinal tract namely Typhoid and Paratyphoid bacteria, Dysentery (Bacillary and amoebic) and Cholera bacteria and enteric virus. Among the micro-organisms 61% bacteria are water-borne pathogens. Samples of surface, ground and drinking water were collected from Jabalpur region. Surface water samples were collected from the river Narmada and Bargi reservoir. Ground and drinking water samples were collected from wells, Hand -pump and Municipal supply. Samples were collected in sterilized borosil glass bottles (Cap. 300ml). These samples were brought in ice bags where the temperature was maintained at 4oC to freeze the activity of microbes present in water. To assess the presence of water borne pathogens, indicator parameters viz. Heterotophic plate count(HPC), Total coliform count (TCC), Feacal coliform count (FCC), Feacal streptococci count(FSC), presence of pseudomonas and Aeromonas and Total count of yeast and mould were studies by standard methodologies recommended by American Public Health Association (APHA, 1995) and Bureau of Indian standards. In comparison to ground and drinking water (collected from well, hand pump and corporation water supply), the surface water (collected from Narmada and impounded water sample from upstream of Bargi Reservoir) showed higher numbers (i.e 2 to 10 times increase in all the indicator parameters). All indicator parameters indicate that there was a sharp decline between Mandla and Bargi Reservoir largely due to the dilution of the point load of sewage from Mandla (river Narmada) and absence of any point source sewage up to Bargi reservoir. All ground water and drinking water sample showed the presence of Coliforms,Faecal streptococci, Pseudomonas, Aeromonas, Yeast and Mould. However, except for some indicator microorganisms, most water samples were found to be contaminated with water-borne pathogens.

Experimental Studies on Current, Susceptance, Impedance and Electrical Modulus of Polypyrrole/Molybdenum Trioxide Composites
Authors: Chaluvaraju B V , P Raghavendra U , Murugendrappa M V
Published: June 2019

Polypyrrole/molybdenum trioxide composites (PPy/MoO3) were synthesized by chemical oxidation method, which involved the polymerization of pyrrole (PPy) with molybdenum trioxide (MoO3). This process involved ammonium persulphate which acted as an oxidizing agent.Diverse compositions of MoO3 such as 10, 20, 30, 40 and 50 wt. % in pyrrole were used to synthesize PPy/MoO3 composites.Scanning Electron Microscopy (SEM) image of the above composites has revealed the presence of multiple phases comprising of MoO3 particles embedded in PPy chain. The observed increase in current could be due to hopping of a large number of charge carriers between favorable localized sites and is attributed to change in the distribution pattern of MoO3 particles.The present study also involved the measurement of susceptance, impedance and electrical modulus, and has disclosed the major influence of dimensions of MoO3 particles present in the matrix on all the properties. The composites discussed in the present study may throw some light on their applications in various areas namely humidity sensor, micro power generator, dielectrics and as semiconductors.

Authors: Sunaja Devi K R , Leethya Mary
Published: June 2019

Gas chromatography-mass spectrometry (GC-MS) and Liquid chromatography mass spectrometry (LC-MS) were used to evaluate the level of different pesticides in some commonly used fruits in Bengaluru region of Karnataka. Although most fruits and vegetable samples analyzed were found to be contaminated with pesticide residues,  they were under maximum residue limit (MRL) after the salted water wash. Samples with residues above MRL may pose health hazards to the consumers. It may be due to lack of awareness of the farmers about the application dose, method of application and withholding period. The findings of this study provide important data about contamination of pesticide residue in some fruits and vegetables sold in Bengaluru.

Published: June 2019

Science and technology are the two wheels of a progressive society. While the research in basic science brings the growth of technology, the developments in technology add input to the diverse fields of science. Basic science is the source of technology. But it is a sorry state of affair that at present the interest in basic science courses such as physics, chemistry, mathematics and biology is dwindling the students. If the trend continues, it will hamper the growth of the nation in all spheres, including the technological front too. The paper tries to highlight the different reasons for this trend and the future implications. Recently the United Nations announced that the year 2005 will be celebrated as the 'International Year of Physics' to remember the great discoveries made by Albert Einstein in the year 1905. It was hundred years ago, in 1905, that he published three historic papers in Annalender Physik which brought out a revolution and a new dimension to Physics in particular and Science in general. Also the year 2005 will be celebrated as the golden year of the discovery od DNA structure by Watson and Crick in 1955. Such celebrations should be a mass movement. The struggle and joy of the great discoveries by great minds should reach to the young minds. This will kindle the interest in them towards Basic Science courses. In the long run the nation will be benefited. It is now the time for responsible men-teachers,parents,educationists,technocrats,media persons and the people in the helm of affairs to discuss the situation prevailing in the field of higher education of basic Science and look for the meaningful solution. The paper also elaborates the in-depth programme conducted by Vivekananda College, Puttur, for the past fifteen years, creating interest among the students of rural schools of the region towards Science.

Impact of Hazardous Industrial Waste on Health and Environment
Authors: V. Anantha Rama , P. Prakash , B.V. Kiran Kumar
Published: June 2019

From the days of primitive society, human and animals have used the resource of the earth to support life and to dispose waste. Rapid population growth and uncontrolled industrial development are seriously degrading the urban and semi-urban environment in many of the developing countries placing enormous strain on natural resources and undermining efficient and sustainable development. Industrial operations lead to considerable generation of hazardous waste and in rapidly industrializing countries such as India the contribution to hazardous waste from industries are largest. Hazardous waste genarations from industries is also critical due to their large geophysical spread in the country, leading to regionwide impacts. Due to liberalization policy the pace of industrialization has been accelerated, which has resulted in increasing amount of hazardous waste every year. This long with a growing amount of municipal solid waste due to rapid urbanization and inadequate policy and technological measures continues to remain a daunting issue of environmental concern to India. In this scenario the present paper discusses various aspects of hazardous industrial waste like its origin, distribution and environmental and health hazards. Hazardous waste from industrial sectors contains heavy metals, pesticides, radioactive materials and other chemicals, which are toxic, flammable, reactive, corrosive, or have explosive properties. Normally Arsenic, Cadmium, Chromium, Copper, Lead, Zinc, Boron etc are found in pulverized fly ash. Cement industries emit huge quality of fluoride into the environment. Large quantity of mercury emitted from caustic soda industries using mercury electrodes, from chemical industries, paper and pulp industries etc. Tin mines emit tin in the vicinity of the mines. The metals such as Cadmium, Lead, Chromium, Arsenic etc, if present in the body, are hazardous to the health. Presence of fluoride within the range of 0.5 to 1.5 ppm is very essential in water for health, if present in excess leads to Florosis. Fouride may cause harm not only through water but also through air by way of respiration and soil. In river estuaries, the concentration of metal traces will reach to a high degrees of contamination because of stagnant water, when industrial effluents are fed into rivers and streams. This paper throws light upon many more such factors and also suggest measures to control and manage hazardous waste.

Comparación de las escalas EQ-5D y FACT-G en la evaluación de la calidad de vida en pacientes colombianos con cáncer
Authors: Valdelamar Jiménez Juliet Rocío , Valdelamar Jiménez Adriana , Fontibón Vanegas Luis Fernando , Acosta Hernández Lorena , Sánchez Ricardo
Published: June 2019

Objetivo: Evaluar patrones de correlaciones entre las diferentes dimensiones de una escala que mide la calidad de vida (FACT-G) y otra que mide la salud autopercibida y la calidad de vida (EQ-5D) en pacientes con cáncer. Material y métodos: Estudio descriptivo que evaluó a 114 pacientes con cáncer de mama (40 = 35.09%), gástrico (26 = 22.8%), próstata (22 = 19.3%), recto (17 = 14.91%), a quienes se les aplicó las escalas FACT-G y EQ-5D. Se utilizaron técnicas de estadística descriptiva para resumir variables, métodos de análisis multivariado, análisis factorial y escalamiento multidimensional. Resultados: Las dimensiones que mostraron valores de correlación aceptable fueron bienestar físico y emocional de la FACT-G con angustia y depresión de la escala EQ-5D. El análisis factorial arrojó dos factores: (a) angustia/depresión de la EQ-5D, que se agrupa mejor con los componentes de la FACT-G, y (b) síntomas físicos con los componentes de la EQ-5D. El escalamiento multidimensional sugirió que cada escala midió dimensiones diferentes del constructo calidad de vida. Conclusión: La evaluación de calidad de vida de la FACT-G parece orientarse a aspectos emocionales y de interacción social; mientras que la de EQ-5D se orienta a aspectos de bienestar físico y funcionalidad.

Authors: Ibañez Claudia , Sánchez Pedraza Ricardo , Oliveros Ricardo
Published: June 2019

Objetivo: Validar la escala EORTC QLQ-STO22 para medir la calidad de vida en pacientes con cáncer de estómago en Colombia. Métodos: A 442 pacientes con diagnóstico de cáncer de estómago (entre 26 y 90 años), les fue aplicado el cuestionario EORTC QLQ-STO22. Se evaluó la validez de contenido con técnicas de análisis factorial; la validez de criterio concurrente comparando puntuaciones de la escalas QLQ-STO22 y FACIT-Ga; la consistencia interna mediante alfa de Cronbach, la confiabilidad prueba-reprueba por medio del coeficiente de correlación concordancia de Lin y la sensibilidad al cambio luego de una intervención terapéutica comparando medias en mediciones repetidas. Resultados: El análisis factorial confirmó una estructura de cinco dimensiones y el análisis confirmatorio mostró aceptable ajuste del modelo. Las correlaciones más fuertes entre la escala EORTC QLQ-STO22 y FACIT-Ga se observaron con los dominios “Estado físico general de salud” y la subescala específica para cáncer gástrico de la escala FACIT-Ga. Se encontró alta consistencia interna con valores de alfa de Cronbach de la escala global de .897. La medición de la confiabilidad prueba-reprueba reportó valores del coeficiente de correlación concordancia de Lin entre .656 y .851. Las diferencias entre puntuaciones antes y después de una intervención terapéutica solo fueron significativas para los dominios disfagia y restricciones para comer. Conclusión: La escala EORTC QLQ-STO22 es un instrumento válido y confiable para medir calidad de vida en pacientes colombianos. Se recomienda efectuar estudios adicionales para confirmar los hallazgos reportados durante la evaluación de la sensibilidad al cambio de esta escala en población colombiana.
Espiritualidad, religiosidad y enfermedad: una mirada desde mujeres con cáncer de mama
Authors: Puentes Silva Yesica Milena , Urrego Sandra Carolina , Sanchéz Pedraza Ricardo
Published: June 2019

La presente indagación buscó explorar el lugar de la espiritualidad y de la religiosidad en la manera como un grupo de mujeres con cáncer de mama asumen, significan y enfrentan su enfermedad. Para ello se efectuó el análisis cualitativo de una serie de entrevistas en profundidad realizadas a un grupo de cuatro mujeres participantes en una “intervención basada en espiritualidad” del Instituto Nacional de Cancerología. Tras un ejercicio de examen y confrontación teórica, se logró una aproximación a los modos de agenciamiento e interpretación de los eventos de la enfermedad, los cuales, a su vez, se ven cruzados por concepciones y prácticas relacionadas con “lo espiritual” y “lo religioso”, así como por el saber médico. Las ideas de las mujeres sobre enfermedad y cuidado revelan una conjunción de estos elementos. Principales categorías emergentes: espiritualidad, religiosidad y enfermedad.

Published: June 2019

En el 2011 la revista Avances en Psicología Latinoamericana dio inicio a una nueva política según la cual la Dirección/Edición de la revista tendría períodos de duración de cinco años. A finales del 2015 terminaremos ese primer periodo y para el período 2016-2020 fueron nombrados como Director y Editora General de la revista los Dres. Miguel Gutiérrez y Luisa Ramírez, respectivamente. El propósito de esta Editorial es efectuar un balance de la gestión de los últimos doce años de la revista y dejar algunas reflexiones para el equipo sucesor y para la comunidad psicológica latinoamericana y de otras latitudes, que ha participado activamente en diferentes roles (autores, pares revisores, editores, lectores, entre otros). El fundador de la revista, Dr. Rubén Ardila, confió a finales de 2003 la orientación de la revista Avances en Psicología Clínica Latinoamericana a partir de 2004 a su actual Director (ver Pérez-Acosta, 2008). Bajo aquella nueva administración, la revista se convirtió en Avances en Psicología Latinoamericana
