La ciudad de México ante la ocupación de las fuerzas villistas y zapatistas. Diciembre de 1914-junio de 1915
Authors: Ávila Espinosa Felipe Arturo
Published: March 2019

El autor analiza la actitud y la visión que tuvieron los constitucionalistas y los convencionistas respecto de la cuidad de México, en sus sucesivas ocupaciones entre agosto de 1914 y junio de 1915. Afirma que el carácter agrario de la revolución condicionó la incorporación de la población urbana a los proyectos de los distintos grupos que ocuparon la ciudad. Lo anterior es señalado como la causa de que los ocupantes mantuvieran su condición de elementos exteriores, que se encontraban más preocupados por los asuntos medulares de la Revolución que por los problemas de la población citadina.
El sinarquismo en el Bajío mexicano (1934-1951). Historia de un movimiento social regional
Authors: Serrano Álvarez Pablo
Published: March 2019

El autor elabora la historia del sinarquismo, lo señala como un movimiento regional, mediante el cual la jerarquía católica buscó concienciar a la sociedad y lograr su movilización para defender los derechos de la religión católica. Sin embargo, asegura que el sinarquismo se identificó con problemas sociopolíticos y socioeconómicos de carácter regional, en especial en el Bajío donde contó con mayor apoyo, lo cual evidenció el descontento que muchos sectores tenían inclusive a nivel nacional contra el cardenismo.

Published: March 2019

A non-parametric efficient statistical method, Random Forests, is implemented for the selection of the determinants of Central Bank Independence (CBI) among a large database of economic, political, and institutional variables for OECD countries. It permits ranking all the determinants based on their importance in respect to the CBI and does not impose a priori assumptions on potential nonlinear relationships in the data. Collinearity issues are resolved, because correlated variables can be simultaneously considered.
Territorial Philosophies of Relativity and the Unity of Spain: Ors and Ortega on Einstein and Relativity at the Service of Catalan Noucentisme and the Spanish Republic
Authors: Cat Jordi
Published: March 2019

Tras la Guerra Civil el filósofo catalán Eugeni d’Ors y el filósofo español José Ortega y Gasset ofrecieron una lectura de la teoría de la relatividad de Einstein in la cual conectaron discusiones de unidad y pluralidad con sus respectivas filosofías y proyectos nacionalistas de análisis y reforma política y cultural sintetizantes. Además, frecuentes referencias a Einstein distinguen sus respectivas ideas filosóficas, sus preocupaciones territoriales y sus circunstancias personales en relación a Cataluña, España y Europa. La teoría de Einstein simbolizó la conexión salvadora entre lo clásico y lo moderno, Europa y el Mediterráneo, y ciencia y filosofía. En este artículo analizo los casos inseparables de Ors en relación con el nacionalismo catalán y al proyecto que denominó Noucentisme y de Ortega en relación con el nacionalismo español y a su filosofia política articulada en La España Invertebrada.
Estudio de prefactibilidad para la organización comunitaria En la construcción de una central de café cereza en el municipio de la palma, cundinamarca, como opción de paz
Authors: Robayo Rojas Nestor Javier , Suárez Suárez Nubia Esperanza , Pinilla Herrera Cesar Andrés
Published: March 2019

El municipio de la Palma, Cundinamarca tiene como base de su economía la agricultura y la ganadería, siendo el cultivo de café el motor de su desarrollo. La Asociación de Caficultores de la Palma “Asoparibari” ha organizado a familias de la zona, buscando mejorar los procesos de organización comunitaria, productividad y sostenibilidad cafetera. Por otro lado, la Federación Nacional de Cafeteros ha venido impulsados proyectos para la construcción de centrales de beneficio, con lo cual busca mejorar la calidad del grano y el manejo de subproductos. Uno de esos proyectos está enfocado para ser administrado por Asoparibari.

Teniendo en cuenta que el municipio de la Palma tiene 1204 hectáreas cultivadas con café y se concentra principalmente en una zona geográfica, la asociación Asoparibari ha decidido orientar sus esfuerzos en buscar recursos para la construcción y puesta en marcha de una central de beneficio que favorezca cerca de 100 familias de la zona. Sin embargo, surgen dudas como ¿Se justifica la construcción de la central de beneficio? ¿Está en capacidad la asociación de operar la central de beneficio? ¿Cuentan con la suficiente capacidad logística para ejecutar el proyecto?

¿Están los asociados dispuestos a llevar su café a la asociación? ¿Hay suficiente credibilidad en las directivas de la asociación? Estas y más preguntas surgen al momento de pensar en este pro- yecto, ya que, si no se hace un estudio previo, el proyecto se puede convertir en una gran dificultad para la asociación y un desperdicio de recursos tanto económicos como humanos.

Este artículo expone el estudio de prefactibilidad, que determinó la viabilidad técnica para la construcción de una central de café cereza en el municipio de La Palma Cundinamarca, identi- ficando debilidades y fortalezas que permiten realizar recomendaciones para mejorar procesos organizacionales a la asociación de productores Asoparibari sobre la pertinencia de continuar o no con el proceso para la construcción de esta central de beneficio, aplicando la metodología del Índice de Capacidades Organizacionales en Comunidades Cafeteras, ICOCC.

Published: March 2019

Clinically-related basic studies on the behavioral effects of ribavirin treatment are still lacking despite its wide use as an antiviral medication. This paper considers the effects of low ribavirin doses (10, 20 and 30 mg/kg/day) on psychomotor activity (novelty-induced exploratory behavior, d-amphetamine (AMPH, 1.5 mg/kg, intraperitoneal)-induced motor activity), and body weight gain in socially undisturbed adult male Wistar rats 24 h after the first, seventh and fourteenth once-a-day injection. Low doses of ribavirin were tested in an attempt to avoid the recognized systemic side effects related to high-dose usage. None of the singly applied ribavirin doses affected exploratory/spontaneous and AMPH-induced motor behavior (locomotion, stereotypy-like and vertical activity), however, body weight gain was significantly lower after treatment with 30 mg/kg of ribavirin. The 7- and 14-day treatments with 10 and 30 mg/kg/day of ribavirin significantly suppressed novelty-induced locomotion and body weight gain; the 14-day treatment with ribavirin at a dose of 30 mg/kg/ day decreased AMPH-induced stereotypy. These findings indicate that repeated application (up to 14 days) of low ribavirin doses results in low novelty-induced locomotion along with reduced weight gain, accentuating the existence of a U-shaped dose-response relationship with a prolonged duration of ribavirin treatment.

Numerical simulation on downhole flow and temperature fields during drilling with nitrogen jet
Authors: Cai Chengzheng , Ren Keda , Liu Jiangfeng , Liu Shuang
Published: March 2019

In petroleum engineering, nitrogen drilling is an important technology for building wellbores between surfaces and reservoirs. To uncover the downhole flow field and the change rules of rock temperature during drilling with nitrogen jet, we constructed a CFD model by coupling the property equations of nitrogen. The flow fields of nitrogen jet and rock temperature distribution at different times were simulated. Results showed that the high speed nitrogen jet can be efficiently generated because of the nozzle acceleration and the impingement effect can be induced during drilling. The temperature of the nitrogen jet decreased due to the Joule-Thomson effect. This phenomenon suggested that the nitrogen jet induced additional thermal cracks on the bottomhole rock, which was very beneficial for the improvement of rock-breaking efficiency.

Authors: Zhao Xiao , Liu Yigang , Zou Jian , Wang Qiuxia , Liu Hao , Zhang Hua , Jin Hui
Published: March 2019

The supercritical water oxidation is a significant way for the waste disposal. The diffusion of the oxygen in the water at the infinite dilution is simulated at 300 K and 1 atm, and 650 K, 673 K, 773 K, 873 K, 973 K, and 250 atm with the molecular dynamics software. The mean squared displacement method is used to calculate the diffusion coefficient. At 300 K, 1 atm, our calculation gives 0.20 ? 10?8 m2/s, which is very near to three empirical equations. When the condition is beyond the critical point, these empirical equations lost their accuracy, and only Kawasaki-Oppenheim equation can be compared to our calculation results. At supercritical conditions, we illustrate the diffusion coefficients with the Arrhenius equation and the activation energy is 22.54 kJ/mol.

Determining Temporal Changes of Annual Productivity of Bay Laural (Laurus nobilis L.) in the Yenikoy Planning Unit
Authors: MUMCU KÜÇÜKER Derya , SARI Burak
Published: March 2019

The production of non-wood forest products (NWFPs) is performed
with harvesting plans in Turkey. However, insufficient technical capacities,
lack of locational data and the absence of site productivity in the plans threat
the sustainability of NWFPs. The primary objective of this research is to
analyze temporal changes of annual site productivity of bay leave in the Yeniköy planning unit, Turkey. The cover type
maps, forest management plans (1972- 2003) and bay laurel harvest plans (1992-2013)
were used as primary data. Temporal changes of bay laurel productivity were
examined in terms of land use types, developing stages and canopy cover with a
detailed analysis on bay laurel areas with GIS. The results indicated that there
was a remarkable change for spatial distribution and
productivity of bay laurel from
1974 to 2013 due mainly to the differences of inventory design
causing underestimation of productivity. Appropriate sampling technique with
the use of GIS may provide more realistic and accurate estimation of the
productivity. The integration of
NWFPs into forest management plans and sustainable production are possible with
understanding the quantitative relations of NWFPs with the appropriate
variables.

Recommendations of The Ombudsman’s Dilemma: Between Law Enforcement Officials and Protection of Credibility
Authors: Dewi Dyah Adriantini Sintha
Published: March 2019

The Ombudsman as an external oversight body for official performance, in Fikih Siyasah (constitutionality in Islam) is included in the supervision stipulated in legislation (al-musahabah al-qomariyah). Supervision is done so that public service delivery to the community is in accordance with the rights of the community. This is done because in carrying out its duties, officials are very likely to conduct mal administration, which is bad public services that cause harm to the community. The Ombudsman is an institution authorized to resolve the mal administration issue, in which one of its products is by issuing a recommendation. Although Law No. 37 of 2018 on the Ombudsman of the Republic of Indonesia states that the recommendation is mandatory, theombudsman's recommendations have not been implemented. This is due to differences in point of view, ie on the one hand in the context of law enforcement, but on the other hand the implementation of the recommendation is considered as a means of opening the disgrace of officials. Recommendations are the last alternative of Ombudsman's efforts to resolve the mal administration case, given that a win-win solution is the goal, then mediation becomes the main effort. This is in accordance with the condition of the Muslim majority of Indonesian nation and prioritizes deliberation in resolving dispute. Therefore, it is necessary to educate the community and officials related to the implementation of the Ombudsman's recommendations in order to provide good public services for the community, which is the obligation of the government.

Staying Alive: Science Fiction in the Age of the Anthropocene — Philip K. Dick’s Pessimistic Humanism
Authors: Harvey Tallulah
Published: March 2019

In recent years, literary studies have become increasingly invested in environmentalism. As science reveals the negative impacts of climate change, and demonstrates a growing concern for humanity’s contribution, literature operates as a form of cultural documentation. It details public awareness and anxieties, and acts as a conduit for change by urging empathetic responses and rendering ecological controversy accessible.To explore the relationship between literature and environmental politics, this paper will focus on the work of science fiction writer Philip K. Dick, and his dystopian visions. In his particular brand of sci-fi, there is no future for humanity. Science and technology fail to pave the way for a better and fairer society, but rather towards, as far as Dick is concerned, extinction. He argues that scientific advancement distances us from reality and from a sense of “humanness”. His pessimistic futures are nihilistic but tender; nurturing a love for humanity even in, what he considers to be, its final hours.Unlike the work of other prominent sci-fi writers, Dick’s fiction does not look towards the stars, but is in many ways a return to earth. The barren landscapes of Mars and other planets offer no comfort, and the evolution of the human into cyborgs, androids and post human species is depicted as dangerous and regressive. Dick’s apocalyptic visions ground his readers in the reality around them, acting in the present for the sake of the earth and humanity’s survival. His humanism is critical of grand enlightenment ideas of “progressivism”, and instead celebrates ordinariness. In the shadow of corporate capitalism and violent dictatorial governments, Dick prefers the little man, the ordinary everyday domestic hero for his narratives. His fiction urges us to take responsibility for our actions, and prepares us for the future through scepticism and pessimism, and a relentless fondness for the human.

Süt yağı, tereyağı ve

krema gibi bazı süt ürünlerinin ana maddesi olmasının yanı sıra, çeşitli süt

ürünlerinde de kalite artırıcı bir bileşendir. Dünya çapında artan süt üretimi

ve tüketicilerin beslenme alışkanlıklarının değişmesiyle yağ içeriği düşük ürünlere

artan eğilim, süt yağı ve tereyağında üretim fazlasının oluşmasına neden

olmuştur. Süt yağının raf ömrü kısadır ve oksidasyona karşı dayanıksızdır. Oda

koşullarında tereyağı olarak depolandığında yaklaşık 4 hafta, buzdolabı

koşullarında ise yaklaşık 6 ay bozulmadan saklanabilmektedir. Ancak soğukta

depolama seçeneği çok maliyetlidir ve süt yağının kurutulması önemli bir

dayandırma alternatifi olarak öne çıkmaktadır. Süt yağı püskürtmeli kurutma

yöntemi ile toz forma dönüştürülebilmektedir. Ancak kurutulmuş halde dahi süt ve ürünlerinin

tozlarında yağ oksidasyonu ve Maillard reaksiyonu gibi olumsuz değişiklikler

gözlenebilmektedir. Mikroenkapsülasyon yöntemiyle, kolayca bozulabilen

gıdaların korunması, çevresel faktörlere daha dayanıklı, daha kararlı ürünlerin

elde edilmesi mümkündür. Bu çalışmada, süt yağının toza dönüştürülmesinin önemi

ile krema tozu ve üretimi açıklanmış, süt yağının toza dönüştürülmesi alanında

yapılmış bilimsel çalışmalar özetlenmiştir.

Published: March 2019

Os lastros constituintes da superestrutura de vias permanentes, quando submetidos a cargas cíclicas de alta intensidade e frequência, sofrem desgaste rápido em sua estrutura portante. Os desguarnecimentos e nivelamentos dos lastros demandam grandes volumes por quilômetro devido à sua degradação. Seus ombros e altura mínimos de construção definem contornos de seções com largas bases de brita. Devido a isso, o desgaste do particulado e seus custos de manutenção inflam o orçamento das ferrovias. Com esse mote, escolheu-se aqui caminhar por um itinerário investigativo cujo paradigma tem seu cerne no conceito de confinamento e seus efeitos sobre o Módulo de Resiliência do lastro. A pesquisa se manteve nos efeitos práticos de reforços por geogrelhas aplicado dentro do corpo do lastro e não na interface com a camada subjacente. Nesse trabalho atingiu-se o objetivo proposto de levantar parâmetros diretivos para orientar ensaios de desempenho de reforços e possibilitar a melhor compreensão das causalidades decorrentes das propriedades específicas das geogrelhas como abertura da malha e rigidez dos elementos, bem como correlacionar o efeito da cota de posicionamento do reforço e os efeitos sobre o grau de confinamento gerado.
Diseño de Software para comparar los algoritmos de Stehfest e Iseger para inversión Laplaciana en pruebas de presión
Authors: Escobar Freddy Humberto , Leguízamo Fabián Andrés , Cantillo José Humberto
Published: March 2019

Este artículo presenta el diseño de un software cuyo objetivo es realizar la comparación de dos algoritmos que sirven para determinar la transformada inversa de Laplace. Esta comparación se lleva a cabo mediante la evaluación dos modelos matemáticos de pozos muy comunes en la industria petrolera que están dados en el dominio de Laplace, para los cuales se realiza la inversión y se grafican los resultados para establecer comparación. La herramienta de software se desarrolla en Visual Basic 2008, y consta de una interfaz gráfica que permite visualizar las inversiones realizadas por cada algoritmo y también genera dos archivos de texto donde se encuentran los datos de tiempo, presión y derivada de presión. La interfaz gráfica brinda varias opciones como poder escoger el modelo de pozo deseado o introducir mediante teclado otro modelo o función que se quiera invertir, también ofrece la opción de suprimir o agregar la gráfica de la derivada y de realizar las gráficas en escala logarítmica. El estudio permitió establecer que el algoritmo de Iseger maneja más eficazmente las discontinuidades de una función y se observó que para casos de pruebas de presión que al cumplir las condiciones que relacionan el tiempo con el número de puntos muestreados, se garantizan unos resultados de inversión más estables. También se comprobó que entre más puntos de inversión se usen, se obtienen unos resultados más precisos. Se encontró, además, en el parámetro nrp de 3 genera inversiones más estables que el propuesto originalmente por Iseger con valor de 8.

Authors: Pham Hung Vuong
Published: March 2019

In this article carbon quantum dots (Cdots) were prepared by a facile, green, economical hydrothermal method of the mixed deionized water and lemon juice. Optical and structural properties of the Cdots have been extensively studied by UV–visible and fluorescence spectroscopy, x-ray diffraction (XRD) techniques, and high resolution TEM (HR-TEM). Surface functionality of Cdots has been illustrated by Fourier transform infrared spectroscopy (FTIR). The fabricated Cdots emit bright green light with broad spectrum. The Cdots exhibit captivating sensitivity and selectivity toward Fe3+ with a linear range from 0 to 80 ppm and a detection limit of 38.08 ppm.
Indigenous Medical Knowledge and the Experiences of ZIPRA Guerrillas in Zimbabwe's Liberation Struggle
Authors: Chakawa Joshua S.
Published: March 2019

This article aims to examine the importance of indigenous medical knowledge during the 1970s when guerrillas from the Zimbabwe People’s Revolutionary Army (ZIPRA) negotiated their way to the front to fight the Rhodesian white minority regime. From the 1960s until the ceasefire at the end of 1979, ZIPRA was one of the two liberation movements that waged war to liberate Zimbabwe. This article traces the experiences of guerrillas who moved from the Zambian side of the Zambezi Valley into Rhodesia. The terrain that the guerrillas had to navigate on foot was punctuated by many devastating and life - threatening challenges. Some of these included malaria, sleeping sickness, venereal diseases, snake bites, mental disorders, injuries and even fatigue. Given that the guerrillas had no hospitals and other medical facilities at their disposal, it is important to establish how local knowledge assisted them to survive, especially when ailments struck them. The purpose of this study was to determine the role the fighters’ knowledge of indigenous medicines played in dealing with these difficulties. The author collected information by conducting interviews with former ZIPRA guerrillas who had operated in Zimbabwe during the war. Some civilians who were in ZIPRA operational areas were also interviewed. The importance of the study lies in understanding the continued use and existence of indigenous medical remedies in Zimbabwe. Findings from the study are valuable in widening knowledge horizons on indigenous medical knowledge as a useful alternative in times of need.

The use of cosmetic formulations that preserve the environment and are more biocompatible with human organisms is indispensable. And as there is the growing demand on the part of consumers, who are increasingly demanding to acquire more interesting cosmetic formulations, so that they can solve problems present in the capillary wire, such as, dryness, absence of brightness, presence of oiliness, among other aspects. Consumers want to direct the existing benefits in beauty salons, and TV commercials, among other means of disseminating knowledge, into their homes. These are looking to associate the cost of the finished cosmetic product with the benefit that this brings the skin. In this research we used the continuation of the studies of the scientists Araújo, Giudici and Sousaa and b, in 2018, in the development of a nanobiotechnological input of microalgae, Chlorella pyrenoidosa, which was registered in the USP-2018 patent. Thus, in this research we analyzed a cosmetic formulation, shampoo, in which the nanobiotechnological supply of this microalgae was used.

Esse estudo buscou identificar as diversas formas de saberes e fazeres populares sobre a influência dos alimentos “reimosos” no processo de cicatrização relacionando a enfermagem transcultural no ato de cuidar.  A experiência se deu a partir da elaboração e aplicação de uma cartilha contendo as práticas e cuidados saúde/doença dos povos ribeirinhos sob a ótica da teoria transcultural e a relação com os alimentos “reimosos”. A teoria de enfermagem transcultural permite que os profissionais da enfermagem tenham um olhar holístico sobre seu cliente, e dessa forma, proporcionem um cuidado que respeite as diferenças culturais existentes, assim como a tecnologia leve permitiu difundir melhor esse conhecimento. Dessa forma, a população ribeirinha amazônica possui conhecimentos próprios sobre os alimentos considerados “reimosos” e os profissionais de saúde devem respeitar esse conhecimento, utilizando-os para agregar no processo de cuidar.

Role of Program for Results (P for R) Financing System in Infrastructure Sector: Evidence from Egypt and Ethiopia
Authors: Abdou Doaa Salman
Published: March 2019

This study aim are two folds: first is to investigate the role of the World Bank funding via using a novel financing instrument called Program-for-Results (P for R) to strengthen the government programs. Secondly assessing the P for R programâ€™s adopted in countries focusing on the directly effects and the results. The Bank Currently has three integral financing options to offer client countries: Investment Project Financing supports specific projects and disburses against specific expenditures and transactions; Development Policy Lending supports policy and institutional reforms and provides general budget support, and Program-for-Results financing supports government programs and disburses against results. Results for the P for R reflect on the new level because disbursements are directly linked to the achievement of measurable and verifiable outcome. As well, the Disbursement-Linked Indicators (DLIs) are used to provide governments with incentives to achieve critical program milestones and enhance the performance of programs. This study structured based on descriptive and observing the behavior of two countries government (Egypt and Ethiopia) for using of P for R financing loan in a national project. On ground the field of practices was the main indicator in this stage of the investigation, then one of P for R programs was compared to observe the effectiveness of this kind of financing system in this two countries specifically in the infrastructure sector, classifications of DLIs were the main parameter in this comparison. The outcome and the existing literature are analyzed to develop a multi-beneficial for country adopting P for R collaborative programs, as they should be applied to mitigate the same challenges and solve the institutional complications for the beneficial countries homogeneously. Furthermore, enhance the profit of this kind of program more than individually as a kind of sustainable management. Â Â Â Â Â Â Â Â Â
Impact of capitulum structure on reproductive success in the declining species Centaurea cyanus (Asteraceae): small to self and big to flirt?
Authors: Penet Laurent , Marion Benoit , Bonis Anne
Published: March 2019

Attracting pollinators and achieving successful reproduction is essential to flowering plant species, which evolved different strategies to cope with unpredictable pollination service. The ability of selfing is most widespread and represents a reproductive insurance under varying conditions. In this study, we investigated reproductive success in Centaurea cyanus, a self-incompatible declining Asteraceae species. We measured seed set under outcrossing and autonomous selfing and assessed the impact of capitulum structure (i.e., the number of disc florets) on reproductive success. We report that the incompatibility system is either flexible or evolving a breakdown in this species, since autonomous selfing often resulted in production of few seeds. We also show that capitulum structure has a strong impact on reproduction, with smaller inflorescences presenting a better ability to self than larger ones, while larger inflorescences performed better than smaller ones when cross-pollinated. Variable capitulum structure in this Asteraceae species may therefore represent a reproductive strategy to achieve efficient reproduction under diverse pollination environments. Our results also suggest that this declining species might be disrupting its auto-incompatibility system in response to reduced habitats and declining population sizes.
