Effect of Co-precursor Maliec Anhydride on the Thermal Decomposition of Acetyl Ferrocene: A Reaction Kinetic Analysis
Authors: Das Bratati , Bhattacharjee Ashis
Published: February 2019

Background:

Thermal decomposition of iron-bearing organometallic complex
acetyl ferrocene, (C5H4COCH3)Fe(C5H5), leads to hematite (α-Fe2O3) nanoparticles. Presence
of maliec anhydride, C4H2O3 as co-precursor during thermal decomposition modifies
the size of the particles as well as the quantity of the reaction product significantly.

Objective:

Kinetic analysis of the solid-state thermal reaction of acetyl ferrocene in the
presence of varying amount of co-precursor maliec anhydride under inert reaction atmosphere
has been studied in order to understand the reaction mechanism involved behind the
formation of hematite and the role of co-precursor in the reaction process. For this purpose,
reaction kinetic analysis of three mixtures of acetyl ferrocene and maliec anhydride has
been carried out.

Methods:

Thermogravimetry under non-isothermal protocol with multiple heating rates
has been employed. The data are analyzed using model-free iso-conversional kinetic techniques
to estimate the activation energy of reaction and reaction rate. The most-probable
reaction mechanism has been identified by master plot method. The kinetic triplets (activation
energy, reaction rate, most probable reaction mechanism function) have been employed
to estimate the thermodynamic triplets (ΔS, ΔH and ΔG).

Observations:

Acetyl Ferrocene (AFc) undergoes thermal decomposition in a four-step
process leaving certain residual mass whereas maliec anhydride (MA) undergoes complete
mass loss owing to melting followed by evaporation. In contrast, the (AFc1-x-MAx) mixtures
undergo thermal decomposition through a two-step process, and the decompositions are
completed at much lower temperatures than that in AFc. The estimated activation energy
and reaction rate values are found strongly dependent on the extent of conversion as well
as on the extent of mixing. Introduction of MA in the solid reaction atmosphere of AFc in
one hand reduces the activation energy required by AFc to undergo thermal decomposition
and the reaction rate, while on the other hand varies the nature of reaction mechanism involved.

Results:

The range of reaction rate values estimated for the mixtures indicate that the activated
complexes during Step-I of thermal decomposition may be treated as ‘loose’ complex
whereas ‘tight’ complex for the Step-II. From the estimated entropy values, thermal
process of (AFc1-x-MAx) mixture for Steps I and II may be interpreted as ‘‘slow’’ stage.

Conclusion:

Variation of Gibb’s free energy with the fraction of maliec anhydride in the
mixtures for Step-I and II indicate that the thermal processes of changing the corresponding
activated complexes are non-spontaneous at room temperature.
Immobilization of Purified Fungal Laccase on Cost Effective Green Coconut Fiber and Study of its Physical and Kinetic Characteristics in Both Free and Immobilized Form
Authors: Ghosh Priyanka , Ghosh Uma
Published: February 2019

Background:

Laccases are important enzymes that have numerous applications in different biotechnological sectors.

Objective:

The aim was to purify laccase from Aspergillus flavus PUF5, successfully immobilize it on coconut fiber and characterize different physical and kinetic properties under both free and immobilize conditions.

Methods:

Laccase from A. flavus PUF5 was purified using ammonium sulfate precipitation, followed by DEAE column chromatography and gel filtration using Sephadex G100. The molecular weight was determined through SDS-PAGE (12%). It was immobilized on pretreated coconut fiber through crosslinking by glutaraldehyde (4% v/v). Physical and kinetic parameters like optimum temperature, pH, thermostability, the effect of additives, activation energy, Km and Vmax for free and immobilized laccase were also analyzed. Recycling stability of the immobilized laccase was further determined.

Results:

The extracellular laccase (65 kDa) was purified up to homogeneity and was immobilized on acid-pretreated coconut fiber by 4% (v/v) glutaraldehyde solution at 30°C, pH 5.0. Activation energy (Ea) of free and immobilized laccase for oxidation of guaiacol was found to be 24.69 and 32.76 kJ mol-1 respectively. Immobilized laccase showed higher melting temperature (Tm) of (82.5°C) than free enzyme (73°C). Km and Vmax for free and immobilized laccase were found to be 0.67 mM, 0.70 mM and 280 U/mg, 336 U/mg respectively when guaiacol was used as substrate. Additionally, in immobilized condition laccase retained ˃80% of its initial activity after use till six repeated cycles.

Conclusion:

The purified laccase enzyme and the cheap immobilization seem to be a prospective process for different biotechnological and industrial applications.
Evaluating the Implications of Climate Projections on Heat Hardiness Zones for Green Infrastructure Planning
Authors: Sylvester Linda , Omitaomu Olufemi A. , Parish Esther S. , Bhaduri Budhendra L.
Published: February 2019

Background: Green Infrastructure (GI) is widely being promoted as an adaptation
strategy for urban flooding. Like urban flooding, tree species could be impacted by future
climatic conditions. However, there have been limited studies on the implications of future
climate on GI planning, mostly due to the lack of climate data at higher spatial resolutions.

Objective:

In this paper, we analyze the implications of climate projections on heat hardiness
zones since this could impact the GI landscape in the coming years. This is an extension of
our earlier work on evaluating impacts of climate projections on plant hardiness zones.

Method: Using downscaled daily temperature data from ten Coupled Model Intercomparison
Project Phase 5 (CMIP5) climate models for the historical (1980 - 2005) and projected (2025
- 2050) periods, we analyzed future heat hardiness zones in the watershed bounding Knox
County, TN. We analyzed the implications of these outputs for the current list of suggested
native and non-native tree species selected for GI in the study area.

Results:

All the models suggest that a considerable part of the study area will move into the
next warmer heat zone. While most trees remain suitable for GI, several are at the limit of
their ideal heat zones.

Conclusion:

The insights from this study will help guide the selection and placement of GI
across the study area. Specifically, it should help green infrastructure planners design better
mitigation and adaptation strategies to achieve higher returns on investments as more cities
are now investing in GI projects.
Mining of Closed High Utility Itemsets: A Survey
Authors: Singh Kuldeep , Singh Shashank S. , Luhach Ashish K. , Kumar Ajay , Biswas Bhaskar
Published: February 2019

Finding High Utility Itemsets (HUIs) is one of the major problems in the area of frequent
itemsets mining. However, HUIs mine lots of redundant itemsets which degrade the performance
and importance of high utility itemsets mining. For overcoming this limitation, closed HUIs mining
has been proposed. Closed high utility itemsets mining finds complete and non-redundant itemsets.
In this paper, we give recent studies on closed high utility itemsets mining algorithms. The main
goal of this survey is to provide recent studies and future research opportunities. We give taxonomy
of closed high utility itemsets mining algorithms. This paper provides a rough outline of the recent
work and gives a general view of closed high utility itemsets mining field.
‘A cannon's burst discharged against a ruinated wall’: A Critique of Quantitative Methods in Shakespearean Authorial Attribution
Authors: Auerbach David
Published: February 2019

Authorship studies has, over the last two decades, absorbed a number of quantitative methods only made possible through the use of computers. The New Oxford Shakespeare Authorship Companion presents a number of studies that utilize such methods, including some based in machine learning or “deep learning” models.This paper focuses on the specific application of three such methods in Jack Elliott and Brett Greatley-Hirsch’s “Arden of Faversham and the Print of Many.” It finds that their attribution of the authorship of Arden to William Shakespeare is suspect under all three such methods: Delta, Nearest Shrunken Centroid, and Random Forests. The underlying models do not sufficiently justify the attributions, the data provided are insufficiently specific, and the internals of the methods are too opaque to bear up to scrutiny. This article attempts to depict the internal flaws of the methods, with a particular focus on Nearest Shrunken Centroid.These methodological flaws arguably arise in part from a lack of rigor, but also from an impoverished treatment of the available data, focusing exclusively on comparative word frequencies within and across authors. A number of potentially fruitful directions that authorship studies are suggested, that could increase the robustness and accuracy of quantitative methods, as well as warn of the potential limits of such methods.
The Particle ??: A Key Aspect to Fathom in Translation with Special Reference to the Holy Quran
Authors: Eddin, MCIL, CL Eyhab Abdulrazak Bader
Published: February 2019

Cognizant of the deep chasm between the actual semantics of the particle ?? and the superficial way it is understood and thus translated, I have decided to devote this study to minutely examine the two types of ??. The paper explores the interrogative and declarative ?? along with their characteristic features, meaning and their realizations in translation into English, with a special reference to the Quran. Fresh tides of thought have conquered me to clarify the semantics of ?? which often fetters trainee translators and students of translation when they- in vain- try to capture the exact meaning of each of them. It is hoped that this paper helps its readers gain practical mastery of some salient features of the Arabic language. It aims at developing readers’ level of linguistic competence.
Entre la obediencia y la libertad. Una mujer española del siglo XVII
Authors: Ordorika Teresa
Published: February 2019

El siguiente artículo muestra cómo los procesos inquisitoriales auxilian en el análisis histórico y sociológico de la sociedad española (y sus colonias). En particular, estos documentos nos permiten conocer las vidas y pensamientos de personas cuya existencia no es registrada en otro tipo de fuentes. Tal es el caso de las mujeres, sobre todo las de estratos bajos. El proceso aquí presentado trata de una de ellas: Theresa Corella. Su caso nos permite atisbar algunas de las posiciones socialmente aceptadas abiertas a las mujeres de su época, así como las maneras en que éstas podían combinarse para lograr espacios de libertad. También posibilita el análisis de la forma en que los poderes eclesiásticos y genéricos trataron de controlar a estas mujeres.
Estructura y discurso de género en tres deidades del panteón afrocubano
Authors: Romeu Vivian
Published: February 2019

Este trabajo analiza una serie de paralelismos entre la estructura mítico-funcional de tres deidades del panteón afrocubano y los roles de género tradicionales de los hombres y mujeres en Cuba, así como los “ajustes” de dichas funciones a favor de un discurso de género dominante y legitimado por las prácticas culturales. El análisis ha sido abordado desde las coordenadas del análisis del discurso y a través de la herramienta hermenéutica, mismas que nos han permitido indagar en la orientación que los llamados ajustes, así como la propia operatividad de las deidades para el imaginario simbólico, ha tenido en función del discurso de género tradicional.
Visión de la prensa respecto a la situación de adicción entre las mujeres mexicanas, 1997-1999
Authors: Peimbert Adriana
Published: February 2019

El artículo presenta los resultados cuantitativos y cualitativos obtenidos de una investigación en la que se analizaron los contenidos noticiosos que once periódicos mexicanos publicaron con relación a las adicciones de las mujeres mexicanas durante los años 1997, 1998 y 1999. El análisis muestra la magnitud en la que fueron abordadas las noticias sobre adicciones así como a los emisores que se pronunciaron al respecto. La investigación utilizó como fuente al Boletín de Información Periodística en Salud, editado por la Universidad Autónoma Metropolitana, Xochimilco. Los hallazgos indican que la prensa publicó escasa información sobre este problema y se dedicó más a difundir datos sobre el número de adictas, muertes y daños que se generan en el feto, durante el embarazo, que a explicar las causas de la adicción y cómo prevenirla.

La prensa escrita en México frente al cambio de régimen
Authors: Salgado Andrade Eva
Published: February 2019

Este artículo aborda el discurso de la prensa escrita para encontrar evidencias sobre los elementos lingüísticos y semióticos para recrear la realidad, funcionar como intermediaria entre diversos actores sociales o convertirse, ella misma, en actor político. El análisis abarca todos los materiales publicados entre el 3 y el 7 de julio del 2000 en diez periódicos de circulación nacional, en torno a los resultados electorales: 838 notas, editoriales, artículos, columnas, entrevistas y reportajes. La selección obedece a que, luego de las elecciones presidenciales en México, se consiguió captar masivamente la atención de la opinión pública, al suponer que con este resultado se hacía posible la alternancia política en México y terminaban siete décadas de hegemonía del Partido Revolucionario Institucional (PRI). Por medio de una metodología original aplicada al análisis de un corpus exhaustivo, se demuestra la utilidad de las perspectivas interdisciplinarias para la investigación en ciencias sociales.

Authors: Wieviorka Michel
Published: February 2019

En este artículo, el autor explica el racismo en general y en Francia en particular. Después de comentar los cambios del racismo de los años 70 a los 90 del siglo XX, explora las modalidades del mismo, a saber: institucional, cultural, religiosa, clásica y científica así como también el neoracismo. A partir de ello, el autor se cuestiona una serie de preguntas que servirán como hilos conductores de su exposición. Además, complementa este análisis al ubicar al nuevo el racismo como un producto de los procesos de globalización caracterizados por sus dimensiones nacionales e internacionales. Concluye que el racismo es más problemático hoy que antes, ya que crece en función de la evolución interna de las sociedades y de las fragmentaciones culturales de grupos diferentes con respecto a identidad, memoria, cultura, pertenencia étnica y religiosa, entre otros factores.
Estudio retórico-comunicativo de los debates presidenciales mexicanos
Authors: Balbuena de la Fuente Felicísimo
Published: February 2019

En su Retórica, Aristóteles distinguió materiales de prueba personal (ethos), argumentales (logos) y dramáticos, o de experiencia (pathos). También distinguió entre discursos judiciales, deliberativos y epidícticos o demostrativos. El autor de este trabajo quiere demostrar que la Retórica de Aristóteles sigue vigente analizando los debates presidenciales mexicanos en 2006. Se ocupa de cómo cada candidato se atuvo a las normas de los debates, su concepción del público y cómo emplearon los tres tipos de materiales. Asimismo, ilustra sus afirmaciones con numerosos ejemplos.

La construcción de la agenda de poder
Authors: Dorantes Gerardo L.
Published: February 2019

El poder constituye el tema central de muchos estudiosos de las ciencias políticas para comprender las distintas formas de la democracia. Los procesos de fijación de las agendas (mediática, pública y política) involucran el uso del poder individual y colectivo. El estudio de la construcción de la agenda política se enfoca el estudio del poder de los temas, una investigación más específica que el tema del poder. El objetivo de este trabajo es hacer un repaso actualizado de las formulaciones y del proceso de estructuración de la agenda a partirde sus tres tradiciones dominantes de investigación: el establecimiento de la agenda pública y, sobre todo, la construcción de la agenda política. La pregunta crucial sería si el proceso de construcción de la agenda conlleva a la solución de los problemas sociales más relevantes, promoviendo el cambio social y manteniendo la estabilidad del sistema político.

Deconstrucción y biopolítica. El problema de la ley y la violencia en Derrida y Agamben
Authors: Pereyra Tissera Guillermo Damián
Published: February 2019

En este artículo, el autor analiza el modo como Jacques Derrida y Giorgio Agamben entienden la relación entre la justicia, el derecho y la violencia y explora las razones de los desacuerdos que mantiene cada enfoque –deconstrucción y biopolítica, respectivamente– en la comprensión de los conceptos antes mencionados. Sin desconocer las diferencias, propone, además, que el desacuerdo entre deconstrucción y  biopolítica no impide encontrar puntos de contacto entre dos autores que abordan el problema de la justicia desde una perspectiva pos-fundamentalista. Finalmente, concluye que deconstrucción y biopolítica están enfrentadas pero no en términos de una oposición pura o tajante.

Las raíces anti-sistémicas del Partido Acción Nacional
Authors: Gómez Peralta Héctor
Published: February 2019

El trabajo analiza a los diferentes grupos que integraron al Partido Acción Nacional (PAN). Contrario a la idea difundida por el PAN y sus simpatizantes de que ese partido nació con un perfil ciudadano y con un proyecto democrático, este artículo muestra cómo el programa de los primeros panistas era heredero de dos diferentes corrientes conservadoras, pero al mismo tiempo anti-sistémicas: por un lado, los herederos de la tradición social-católica, continuadores de la lucha contra el Estado jacobino surgido de la revolución; por el otro, la derecha secular que buscaba la industrialización económica y modernización administrativa del Estado mexicano, teniendo como referente a la tradición hispanista de la Falange española.

Class and Structural Inequality of fishing communities in Ambon City
Authors: Attamimi Gadri Ramadhan , Kinseng Rilus A , Agusta Ivanovich
Published: February 2019

Social class is a social phenomenon that often occurs in every social group including the fishing communities. The structural inequality of fishing communities is characterized by the imbalance in ownership of production equipment and income distribution among fishermen. This research was conducted in one of the  Fishermen Village (Negeri) in Ambon City, called Negeri Latuhalat. Type of research used in this study is post-positivism paradigm using qualitative approach supported by quantitative research. The purpose of this research is to analyze the level of imbalance between Ambon City fishermen. The results showed the formation of fishermen social classes which consist of masnait fishermen, tanase fisherman laborer, small fishermen, middle fishermen and tenant fisherman (capitalist). The gini index of fishermen in the research location shows a figure of 0.74, meaning that it shows a high imbalance between fisherman classes. The ratio of kuznets or the average comparison between fishermen received by 33% of the top group of Rp. 8,404,567, - and 25% of the lowest group of Rp. 2.040.000, -. Measurements using the World Bank also show the same thing with the results of gini index measurements that illustrate the portrait of inequality income distribution in the study sites. This condition illustrates that there has been an imbalance between fishermen classes, as much as 75% are only able to receive 8.72% of total income while as much as 25% of tenant fishermen (capitalist) enjoy and control 91.73% of total income.
Novel composite zinc-alginate hydrogels with activated charcoal aimed for potential applications in multifunctional primary wound dressings
Authors: Osmokrovic Andrea , Jancic Ivan , Jankovic-Castvan Ivona , Petrovic Predrag , Milenkovic Marina , Obradovic Bojana
Published: February 2019

Composites based on Zn-alginate hydrogels in the form of beads were produced by extrusion of a suspension containing 0.5 % w/w of alginate and 20 % w/w of activated charcoal (AC) with the intent to simultaneously release two active agents, Zn2+ and AC particles, in a physiological-like environment. The obtained composite beads were analyzed by FE-SEM and characterized regarding textural parameters, as well as Zn2+ and AC release kinetics in the physiological saline solution. Zn2+ions were quickly released reaching the equilibrium concentration within the first hour in the contrary to the release of AC particles, which was described by internal diffusion with the apparent diffusion coefficient of approximately 10-13 m2 s-1. Potential functionality of the obtained beads was evaluated regarding antibacterial activity in suspensions of the standard bacterial strain Escherichia coli 25922. The observed strong bactericidal effects were related to the quick release of Zn2+ that was not affected by AC. Thus, taking into account results of this study, as well as high sorption capacity of alginate hydrogel, efficiency of AC to adsorb malodor and tissue degradation products and positive effects of Zn2+ on wound healing, the obtained composites have shown promising potentials for applications as multifunctional wound dressings.

Managing Urban Heritage Areas in the Context of Sustainable Tourism, Heritage Conservation
Authors: Jamieson Walter , Engelhardt Richard
Published: February 2019

There has been very little documentation of the Asian experience in planning and managing urban heritage areas, especially those experiencing tourism pressures. In order to better understand the challenges in these areas, 47 case examples have been authored by experienced practitioners who have worked in Asia over the past two decades in the areas of heritage conservation and/or cultural heritage tourism. The issues discussed in the case examples are those that the practitioners have identified as being of particular relevance to the heritage and sustainable tourism debate. Combined, these case examples provide geographic breadth and longitudinal depth, offering a comprehensive and credible body of data.

Lanjut usia (lansia) merupakan seseorang yang mencapai usia > 60 tahun yang rentan mengalami penyakit yang berhubungan dengan proses menua salah satunya hipertensi. Hipertensi merupakan salah satu faktor resiko penyebab terjadinya penyakit kardiovaskuler. Seseorang dikatakan hipertensi jika hasil pengukuran tekanan darah sistolik > 140 mmHg dan diastolik > 90 mmHg. Beberapa faktor resiko diduga memiliki peran dalam terjadinya hipertensi seperti gaya hidup dan pola makan. Penelitian ini bertujuan untuk mengetahui hubungan gaya hidup dan pola makan dengan kejadian hipertensi pada lansia. Penelitian cross sectional ini diikuti oleh 74 responden dengan cara purposive sampling. Hasil penelitian ini mendapatkan proporsi lansia yang mengalami hipertensi sebesar 26,4%. Analisis bivariat menggunakan uji chi-square dan analisis multivariat dengan regresi logistic ganda. Hasil analisis bivariat menunjukkan ada hubungan antara aktivitas fisik (p=0,024 OR=3,596), asupan lemak (p=0,008 OR=4,364), dan asupan natrium (p=0,001 OR=6,103) dengan kejadian hipertensi. Analisis multivariat menunjukkan asupan natrium (OR Exp(B)=4,627) sebagai faktor resiko yang paling berhubungan dengan kejadian hipertensi. Untuk mengurangi kasus hipertensi perlu adanya cara untuk mencegahnya seperti memberikan penyuluhan kepada masyarakat mengenai hipertensi dan bagi penderita penyakit hipertensi untuk selalu mengontrol tekanan darah dan menghindari faktor-faktor yang menyebabkan terjadinya penyakit hipertensi.Kata Kunci: Hipertensi, Gaya Hidup, Pola Makan

Authors: Rymarz Joanna , Niewczas Andrzej , Dębicka Ewa
Published: February 2019

The aim of the article is to compare the operational availability of the city buses. Two popular makes of buses were analysed in the function of time of use, during the six years of operation, in the Municipal Transport Company (MPK) in Lublin. A new division of operating time for the period of full operational usefulness and period of limited operational usefulness of vehicles was presented. It was shown that the average operational availability of the analysed buses differed significantly due to the vehicle's make and also due to the service life. The ANOVA analysis method was used to assess the significance of differences.

Published: February 2019

The paper presents a conceptual design of a laboratory station for measuring the intensity of electromagnetic fields emitted during conversations by mobile phones. A significant part of our society's population is increasingly using cellular telephones. Among them are vehicle drivers who use mobile phones or smartphones more and more often for travel communication and logistics purposes. The use of this type of electronic device carries some risk of exposure to electromagnetic fields (EM). The article presents the results of experimental research on randomly chosen cell phones from the years 2011-2017. The method of taking measurements was carried out as part of the author's engineering work [1]. It should be emphasized that all the results of the EM field tests of telephones used for experimental research were within the limit of the permissible electric field strength of the electromagnetic field of 7 V / m.

Authors: Pałęga Michał
Published: February 2019

Noise is a sound with frequencies from 16 Hz to 16,000 Hz. In addition, the slogan can also be used to describe any unwanted noise that is harmful to human beings, which negatively affects the hearing organ and other senses, and often disturbs the proper functioning of the whole organism. Depending on the source of its origin, the noise can be divided into: communication noise and industrial noise. In addition, the following categories of traffic noise can be distinguished: road (street), rail (rail, tram) and air. The article presents selected measurements of road noise in Poland according to the 2015 study, broken down into national, provincial and other roads (poviat, commune, local), taking into account the time of day and night. In addition, it should be mentioned that measurements of road noise are carried out both by the Provincial Inspectorates for Environmental Protection as part of monitoring or control, as well as road managers.
