Experimental Investigation on the Effect of Casting Parameters on Thin walled Castings of Metal Matrix (LM21-SiC) Composite
Authors: L Venkatesh , Arjunan T.V. , Arulraj M. 
Published: May 2020

Â Metal matrix composites (MMCs) are widely used in several applications owing to their high strength, high specific stiffness, greater wear resistance and light weight. Normally, MMCs are processed through stir casting which exhibits poor wet ability and bonding between metal matrix and ceramic reinforcement, porosity and hot tears. These drawbacks can be overcome by squeeze casting process. Here an attempt was made on processing LM21-Sic composite for making hollow casting through squeeze casting process. Four process parameters are chosen namely squeeze pressure, stirring speed, melt temperature and reinforcement percentage. The primary objective was to experimentally investigate the influence of casting parameters on hardness & wear. Samples were cast for each experiments condition based on L9 orthogonal array. From the analysis of variance (ANOVA), it was observed that stirring speed, reinforcement percentage and Squeeze load were the process parameters making a noticeable improvement in hardness and wear. The mechanical properties such as hardness and wear are evaluated and optimum casting condition was obtained.

Published: May 2020

This article discusses about the influence of Islamic culture in the land of Minahasa of North Sulawesi Province based on archaeological studies. Minahasa is the biggest ethnic area in North Sulawesi Province, with the majority of the population being Christians. Islam arrival in Minahasa carried by Arab traders, fisherman from North Maluku, Bugis, Makasar, Gorontalo and political prisoners from Java and Sumatera. The early history of Islam in Minahasa, acculturation process, development, and Islamic influence in Minahasa can be traced by using archaelogical studies based on existing physical cultural. Research on Islamic culture in Minahasa specifically based on archaeological studies has not been done before. The previous researches of the same topic were mostly conducted through nonphysical culture. The result of the observation reveals that the influence of Islamic culture in Minahasa comprises of some Islamic Settlements, Mosques, and Islamic Cemetery. The influence of Islamic culture in Minahasa coastal area and inland has different characters due to different historical background, socio cultural, and political background of the Islamic communities. Artikel ini membahas mengenai pengaruh kebudayaan Islam di tanah Minahasa, Propinsi Sulawesi Utara berdasarkan tinggalan arkeologi. Minahasa merupakan wilayah etnis terbesar di Propinsi Sulawesi Utara dengan mayoritas penduduk beragama Kristen. Agama Islam di Minahasa dibawa oleh pedagang-pedagang Arab serta, nelayan dari Maluku Utara, Bugis, Makasar, Gorontalo dan tahanan politik dari Jawa dan Sumatera. Dengan menggunakan kajian arkeologi, dapat ditelusuri sejarah awal masuknya Islam, proses akulturasi yang terjadi, perkembangan dan pengaruh Islam di Minahasa berdasarkan tinggalan kebudayaan fisiknya.

Las fuentes de información sobre el empleo público en España: revisión, diagnóstico y propuestas de cambio
Authors: Luxán Meléndez José María de 
Published: May 2020

Para describir el tamaño del empleo público y el volumen del gasto de personal de las administraciones públicas es usual utilizar como referencia una pluralidad de fuentes estadísticas basadas en registros administrativos, y también emplear los datos de Contabilidad Nacional y las estadísticas del mercado de trabajo. Esta diversidad de fuentes y de metodologías conduce necesariamente a una gran disparidad de resultados. En este trabajo en el ámbito del empleo y del gasto de personal se revisa el Inventario de Operaciones Estadísticas sobre las Administraciones Públicas. Y se analiza que la imagen que se construye sobre las retribuciones o sobre el tamaño y características del empleo público y de sus remuneraciones varía en función de la estadística a la que se acuda.
Se presentan nueve figuras sobre el número de empleados, el empleo femenino, el peso del empleo de las Comunidades Autónomas, la temporalidad en el empleo público, y el gasto de personal. Y por último se plantean un conjunto de propuestas para mejorar la transparencia y la eficiencia del sistema de información del empleo y del gasto de personal en el Sector Público.
Transferencia Condicionada de Ingresos en Argentina: una mirada hacia los orígenes de la Asignación Universal por Hijo para la Protección Social (AUHPS)
Authors: Vargas Melisa Cristina 
Published: May 2020

El objeto del presente trabajo es analizar una política particular de transferencia condicionada de ingresos: la Asignación Universal por Hijo para la Protección Social (AUHPS), implementada en Argentina en el año 2009 por la entonces presidenta Cristina Fernández de Kirchner, a través del Decreto de Necesidad y Urgencia N° 1602/09, como un subsistema no contributivo dentro del Régimen de Asignaciones Familiares instituido por la Ley N° 24.714 y bajo jurisdicción de la Administración Nacional de la Seguridad Social (ANSES).
El estudio, metodológicamente basado en el análisis documental, se estructura en torno a una serie de ejes que son imprescindibles examinar de la AUHPS, entre ellos: los antecedentes regionales, el contexto previo a su surgimiento, los aspectos jurídicos normativos que la respaldan, los sujetos de derecho, las consideraciones y debates del feminismo y la mirada peyorativa de los sectores conservadores más reaccionarios que se manifiestan en contra de este tipo de política social que tiende a equiparar en derechos a los hijos e hijas de los trabajadores formales tanto con los de los trabajadores informales como con los de aquellos que se encuentran circunstancialmente desempleados.
China y el Mercosur: oportunidades en el desarrollo de sus relaciones
Authors: Gallego Mendaña Joaquín Andrés 
Published: May 2020

Desde el comienzo de la década de 1990, los países de América del Sur notaron la importancia de las alianzas regionales. Como resultado de este nuevo pensamiento, algunos de ellos decidieron crear un bloque de integración: el Mercado Común del Sur (Mercosur), que nació oficialmente en 1991. Actualmente, Mercosur representa los intereses políticos y económicos de Argentina, Brasil, Paraguay, Uruguay y Venezuela, cuya población supera los 295 millones de personas. Este proceso se convirtió en un pilar para la integración y cooperación comercial de América del Sur, cuyos resultados no habían sido vistos anteriormente en la región. De igual forma, se consolidó como un interlocutor para el acercamiento entre los líderes de los países para el desarrollo de una agenda común. Sin embargo, una gran cantidad de factores internos y externos han impedido al Mercosur alcanzar su máximo potencial.

Meaning and Evolution: Why Nature Selected Human Minds to Use Meaning
Authors: Baumeister Roy F. , Hippel William von 
Published: May 2020

Abstract
We treat meaning as nonphysical connection and potential organization. Meaning is a resource that can be used by animals to improve survival and reproduction. The evolu­tion of brains to exploit meaning occurred in two heuristic steps. First, solitary brains developed mental representations of patterns for learning and guiding adaptive action. Second, humankind greatly expanded the usefulness of meaning by using it collectively, such as by deliberately communicating information, creating a body of shared beliefs and understandings, and using meaning to organize social life. The intentional application of meaning to life, as in the quest for a meaningful life, is a later development linked to ways of organizing behavior to maximize future outcomes and relate the individual to societal systems.
A Scientific Turn in the Genre of How-to Fiction Writing Manuals?
Authors: Veleski Stefan 
Published: May 2020

Abstract
The last two years have seen the publication of two books in the genre of how-to fiction writing manuals that use science both as a selling point and as a genuine analytical par­adigm. The Science of Storytelling by Will Storr and The Science of Screenwriting by Paul Joseph Gulino and Connie Shears use insights from the cognitive sciences and evolution­ary psychology, while retaining their practical, how-to character. This review article goes through some of the main clusters of advice shared by the two books, dealing with infor­mation processing, attention allocation, the implications of human sociality for fiction, and story structure, while fitting their takes on these issues within the fields of biocultural criticism and cultural evolution. Despite containing occasional flaws and confusions about theory common in pioneering works, these books could be harbingers of change for the genre and an important step in the bottom-up infusion of biocultural theory into literary studies.
EFFECT OF COW DUNGS RATE AND SASAKAWA TECHNOLOGY ON THE PERFORMANCE OF MAIZE (ZEA MAYS) IN MUBI GUINEA SAVANNAH OF NIGERIA
Authors: Toungos Dahiru 
Published: May 2020

This experiment was carried out during 2019 cropping season to evaluate the effect of cow dung rates and Sasakawa technology on the performance of maize in Mubi, Northern Guinea Savannah at Food and Agricultural Organization Tree/Crop production farm Adamawa State University, Mubi. The trial was laid out in Randomized Complete Block Design replicated three times. Data was collected on fifteen characters namely: Number of leaves at 3,6 and 9 weeks after sowing also Plant height at 3,6 and 9 weeks after sowing, Cob length, Number of row per cob, Number of seed per row, Cob diameter, Cob yield, Shelling percentage, Grain weight, Grain yield and 100 Grain weight. Results showed a non-significant difference for all the fifteen (15) traits of maize T1 but T4 have better performance. Also, NL3 and NL6, T3, T4 and T5 outperformed in terms of yield, NL3 showed a highly significant positive correlation with NL6, NL9, PH3 and PH6. Cob yield also has slightly and significantly correlation with NL6, CL and NS/R. The treatments respond to variations in the rates of cow dung application during the trial period. As highly significant and positive correlation was observed for NL3, NL6, NL9, PH3, PH6, and PH9 indicating differences in the treatments applied. The experiment revealed that treatment T1, T4 and T1, T4 for NL3, and NL6 gave highest performance than other treatments, followed by T1 and T4 for NL9 which also did well in that order respectively. Cob yield was observed to performed better in T3, T4 and T5. That translates to a very good grain yields in T3 (27kg/ha-1), T4 (16.20kg/ha-1) and T5 (20kg/ha-1). This might be due to the rates of cow dung applied on these treatments. Hence, it is therefore recommended based on the results of the study to use these range of cow dung in the study area. Further research is also recommended to be done in this area for adoption by farmers.

Published: May 2020

The optimal capital structure is conceptualized as a basic framework pertinent to acquiring, utilizing, and contributing financial resources of the organization. The estimation and maintenance of the capital structure of a firm are the integral managerial decisions that could ultimately affect the future of the organizations. No doubt, the potential of profitability is the first thing for its future growth and to inculcate a sense of confidence among investors to invest in the firms. This study aims at examining the nexus between capital structure and profitability of firms in the context of the Oil & Gas sector of Pakistan. The sample of this research is comprised of the top five top-performing firms of the Oil & Gas sector for a period of ten years (2006-2015). Keeping in view the explanatory orientation of this research, quantitative research approach was employed. In order to achieve study objectives, the secondary data were extracted from the financial statements of the firms under study and data were analyzed through descriptive statistics and correlation coefficients. During data analysis, the profitability of the firm was measured in terms of Gross Profit Ratio (GPR), Return on Capital Employed (ROCE) and Return on Equity (ROE). Whereas, the capital structure was measured in terms of Debt to Equity (D/E) ratio and Debt to Total Funds (D/TF) ratio. The findings drawn from this study revealed a negative linkage among various dimensions of the capital structure of firms and their profitability potential in the context of the Oil & Gas sector of Pakistan. Primarily, this study findings corroborated that sample firms under study brought sudden changes in the composition of their debt and equity mix (capital structure) that significantly threatened the profitability of firms. The study suggests that selected firms understudy the need to adopt consistent capital structure policies with a clear understanding of future profitability. Financial managers need to focus on developing prudent optimal capital structure and avoid making abrupt changes in the debt and equity mix of firms.

Published: May 2020

In the whole research process of electromagnetic wave, the research of terahertz wave belongs to a blank for a long time, which is the least known and least developed by far. But now, people are trying to make up the blank and develop terahertz better and better. The charm of terahertz wave originates from its multiple attributes, including electromagnetic field attribute,photon attribute and thermal attribute, which also attracts the attention of researchers in different fields and different countries, and also terahertz technology have been rated as one of the top ten technologies to change the future world by the United States. The multiple attributes of terahertz make it have broad application prospects in military and civil fields, such as medical imaging,astronomical observation, 6G communication, environmental monitoring and material analysis. It is no exaggeration to say that mastering terahertz technology means mastering the future. However, it is because of the multiple attributes of terahertz that the terahertz wave is difficult to be mastered. Although terahertz has been applied in some fields,controlling terahertz (such as generation and detection) is still an important issue. Nowadays, a variety of terahertz generation and detection technologies have been developed and continuously improved. In this paper, the main terahertz generation and detection technologies (including already practical and developing) are reviewed in terms of scientific and engineering principles,in order to provide a systematic and up-to-date reference for researchers in terahertz field.

Published: May 2020

Ferroelectric nano-materials are very sensitive to several external stimuli and have attracted great deal of attention due to their property of improving various properties such as photoluminescence, higher polarization, fast response time, low operating voltage and improved conductivity. For enhancing the physical properties, a proper selection of nano-materials for liquid crystals depends upon various factors such as size, shape, preparation methods, surfactant concentration and amount of doping materials. In the present study an attempt is made to study electrical and acoustical properties of cholesteric liquid crystal after dispersing ferroelectric nano-powder of Barium Titanate (BaTiO3). In addition with this particle size and surface area of pure and nono-particle dispersed liquid crystal were also measured. Our investigation shows increase in Rao’s constant or molar sound velocity, which indicates increase in molecular density indicating a close packing of the material. The measurement of dielectric relaxation at different frequencies gives information about the dynamics of polar groups and molecular motion.
