Experimental study to investigate the performance of cold in-place recycling asphalt mixes
Authors: Ameri Mahmoud , Mohammadi Mohammad Hossein , Motevalizadeh Seyed Mohsen , Mousavi Ahmad
Published: March 2018

This research work was performed to study the impact of steel slag and limestone virgin aggregates as a substitution for recycled asphalt pavement (RAP) in cold in-place recycling (CIR) asphalt mixes. An anionic slow-setting (SS-1) emulsion was used to fabricate the specimens. Marshall stability and flow test, dynamic creep test and moisture susceptibility test were performed to evaluate the mechanical performance of the CIR mixes. The results of this research showed that the presence of modifier aggregates leads to an increase of Marshall stability, and a decrease in permanent deformation and moisture susceptibility. Furthermore, the additional aggregate contents have a significant impact on the moisture and rutting resistance of CIR mixes. Limestone-modified mixes were more resistant to moisture damage. However, steel slag-modified mixes showed better performance against rutting distress.
Modifiye atmosferde paketlemenin ‘0900 Ziraat’ kiraz çeşidinin meyve kalitesi ve derim sonrası ömrü üzerine etkileri
Authors: KURUBAŞ Mehmet Seçkin , SAHIN OZALP Gizem , ERKAN Mustafa
Published: March 2018

Kiraz meyveleri sınırlı muhafaza ve raf ömrü nedeniyle
bozulmalara karşı oldukça hassastır ve bazı durumlarda pazarlama sonrası nihai
tüketiciye optimum yeme kalitesinde ulaşamamaktadır. Bu nedenle, bu çalışmada,
muhafaza ve pazarlama periyodunu uzatmak amacıyla, ‘0900 Ziraat’ kiraz (Prunus
avium L.) çeşidinin derim sonrası ömrü ve meyve kalitesi üzerine modifiye
atmosferde muhafazanın etkileri belirlenmiştir. Bu amaçla kirazlar 3 farklı
modifiye atmosfer ortamında 0°C sıcaklık ve %90-95 oransal nemde 50 gün süreyle
muhafaza edilmişlerdir. Çalışmada birinci grup kirazlar Xtend® marka torbalar
(MAP-1) içerisinde, ikinci grup meyveler deliksiz polietilen torbalarda
(MAP-2),  üçüncü grup kirazlar ise delikli polietilen torbalar
(MAP-3-Kontrol) içerisinde paketlenmiştir. Farklı muhafaza ortamlarından 10 gün
aralıklarla meyve örnekleri alınmış ve meyvelerde farklı fiziksel ve kimyasal
değişimler belirlenmiştir. Çalışmada en düşük ağırlık kaybı MAP-1 ortamında
depolanan kirazlarda tespit edilmiştir. MAP-2 ortamında muhafaza edilmiş
kirazlar en yüksek suda çözünebilir kuru madde miktarına sahip olmuşlardır.
Titre edilebilir asitlik değerleri muhafazanın ilk 10 gününde artmış, daha
sonra ise azalmıştır. En yüksek meyve eti sertliği, titre edilebilir asitlik, L*,
C* ve tat değerleri MAP-1 ortamında depolanan kirazlarda tespit
edilmiştir. Piting ve sap kararmasının kontrol altına alınmasında en etkili MAP
uygulaması MAP-1 olarak belirlenmiştir. Sonuç olarak, ‘0900 Ziraat’ kiraz
çeşidine ait meyveler 0°C sıcaklık ve %90-95 oransal nemde 50 gün süreyle MAP-1
ortamında başarılı bir şekilde muhafaza edilmişlerdir.

Authors: SÜRMEN Mustafa , KARA Emre
Published: March 2018

Bu araştırma, Aydın ili Çakmar Mahallesi meralarının eğimleri farklı 5 kesiminde (%2, %8, %15, %25, %30) yürütülmüştür. Yapılan etütler neticesinde her eğimden 7 adet kuadrat alanı dipten biçilerek örneklenmiştir. Örneklemenin ardından yapılan analizler ve hesaplamalar neticesinde yaş - kuru ağırlık (kg da-1), ADF (%), ADL (%), NDF (%), Ham Protein Oranı (%), Ham Protein Verimi (kg da-1), Sindirilebilir Kuru Madde (%), Nispi Yem Değeri ve ağırlığa göre botanik kompozisyonlar belirlenmiştir. Sonuçlara göre meranın kuru ot verimi 223.03-114.54 kg da-1 değerleri arasında değişirken, en yüksek kuru ot verimi %8 eğimde yer alan merada tespit edilmiştir. En yüksek NDF oranı meranın %30 eğimli kesiminde, en düşük NDF oranı ise %2 eğimli kesiminde ölçülmüştür. Ham protein oranı en yüksek %10.64 ile %8 eğimde görülürken, en yüksek nispi yem değeri 101.35 ile %2 eğimli mera kesiminde ölçülmüştür. Ağırlığa göre botanik kompozisyonda baklagiller familyasına ait türlerin daha az oranda olduğu gözlemlenmiştir. Çalışma neticesinde %2, %8, %15 eğime sahip mera kesimlerinin verim ve kalite bakımından diğer kesimlere oranla daha iyi olduğu görülmektedir. Aşırı otlatmaya maruz bırakılan bu mera alanının, hatalı mera yönetimi sonucunda hayvansal üretime katkısı azalmaktadır. Bu sebeple doğru yönetim prensiplerinin uygulanması ve mera ıslah projeleri ile bölgedeki meraların sorunlarına çözüm bulunabilecektir.
Wie die Helvetier Waldenburg entdeckten. Zur Rezeption von Joanna Bator in der Schweiz
Authors: GERBER Małgorzata
Published: March 2018

Der Text gibt einen Überblick über die Rezeption der Werke Joanna Bators in der Schweiz in den Jahren 2011-2016. Die Schriftstellerin markierte ihre Präsenz in dieser Zeitspanne dank den gelungenen Übersetzungen ihrer drei Waldenburger Romane Sandberg, Wolkenfern und Dunkel, fast Nacht. Die Anerkennung belegen zahlreiche Kommentare in den Medien und zwei Auszeichnungen von 2014: der Literaturpreis Leuk und der Friedrich Dürrenmatt-Preis der Universität Bern.Die Schweizer Leserschaft war von den aus feministischer Perspektive dargestellten Romanen beeindruckt. Im Hintergrund liegen die Waldenburger Landschaft und die Geschichte der Vertriebenen. In den Rezensionen rückte man Bators Fähigkeit in den Vordergrund, Tabus zu brechen und soziokulturelle, darunter auch Geschlechts- und Rasse-Grenzen zu überschreiten. Man schätzte ihre postmodernistische Art hoch ein, verschiedene Genres und literarische Konventionen meisterhaft zu verbinden. Die Aufmerksamkeit der Kritiker fokussierte sowohl auf Bators bildreiche Sprache als auch auf die Leichtigkeit, mit der sie Zeit- und Raumbarrieren überwindet.Die online-Recherchen in den Medien, vor allem in der Alltagspresse, in Radio und Fernsehen erlauben die Feststellung, dass Bators Schaffen sowohl von den Literaturkritikern als auch vom breiten Lesepublikum mit Interesse begrüsst wurde. Man kann annehmen, dass der Buchmarkt in der Schweiz für künftige Texte von Bator offen steht.

Authors:   The Tourism Sciences Society Of Korea, Choi Dong-Heui
Published: March 2018

The purpose of this study is to investigate the relationship influence among life style, tourism information, and behavioral intention on Chinese tourists in Korea, along with the difference in the relationship influence depending on the tourism type (individual tourism or group tourism) and the pertinent implications thereof. In order to accomplish that purpose, Chinese tourists who had visit Korea, departing from Incheon International Airport were selected as subjects for a questionnaire implemented from March 1 to March 31., 2016. A total of 250 questionnaires was distributed and 230 valid copies were used for the empirical analysis. As a result of the study, the life style of Chinese tourists noticeably influenced tourism information and the tourism information perceived by Chinese tourists noticeably influenced behavioral intention with a difference depending on the tourism type (individual tourism or group tourism). Therefore, the study implies that the tourism information provided to Chinese tourists should be differentiated with the newest information taking into consideration life style, tourism type and factors.
Pilgrimage Motivations through Constructivism Grounded Theory: Focused on Christian Pilgrimages
Authors:   The Tourism Sciences Society Of Korea, Lee Yang-Lim , Kim Young-Mi
Published: March 2018

The purpose of this study is to understand the structure of Christian pilgrimage experiences by addressing the question of what the characteristics and influences of pilgrimage motivations are. To investigate the structure of Christian pilgrimage experiences, a qualitative study based on the constructivist grounded theory of Charmaz (2006) was conducted. A total of 32 people who had made a pilgrimage to Israel in the preceding three years were selected as research participants through theoretical sampling. While research on pilgrimages has tended to emphasize religious perspectives, this study focuses on the aspect of bridging the sacred to the secular, which can be considered to be a new aspect of pilgrimages that cannot be found in the existing studies.

Published: March 2018

Este trabalho teve por objetivo avaliar o consumo de combustível da colheita mecanizada de cana-de-açúcar em diferentes velocidades de deslocamento e rotações do extrator primário. O experimento foi conduzido em um canavial colhido sem queima prévia, com a cana-de-açúcar da variedade CTC 15, em seu primeiro estágio de corte e com porte classificado como ereto. O espaçamento entre fileiras foi de 1,5m e a produtividade agrícola média da cultura de 92,5 t ha-1. A colhedora de cana-de-açúcar utilizada foi a de uma linha, operando em três velocidades de deslocamento, sendo V1 (3,0 km h-1), a velocidade V2 (5,0 km h-1) e V3 (7,0 km h-1). Foram utilizadas duas rotações do extrator primário, sendo a R1 de 700 rpm e R2 de 1000 rpm. No experimento foi avaliado o consumo de combustível da colhedora com o uso de fluxômetros assim como o desempenho da mesma. A capacidade de campo efetiva (ha h-1) e o consumo horário efetivo de combustível (L h-1) foram maiores, com o aumento da velocidade de deslocamento da colhedora de cana-de-açúcar e com o aumento da rotação do extrator primário. O estudo mostrou que com o aumento da velocidade de deslocamento da colhedora diminuiu o consumo de combustível por tonelada de cana-de-açúcar colhida (L t-1).PALAVRAS-CHAVE: desempenho; rendimento operacional; avaliação; mecanização. FUEL CONSUMPTION OF SUGARCANE MECHANIZED HERVESTING UNDER PRIMARY EXTRACTOR DIFFERENT SHIFTING SPEEDS AND SPINSABSTRACT: This study aimed to evaluate the fuel consumption of mechanized harvesting of sugar cane under different speeds of displacement and rotation of the primary extractor. The experiment was conducted in a sugar cane variety CTC 15 in its first cutting stage and size classified as erect, harvested without burning. The row spacing was 1.5 m and the average agricultural crop yield of 92.5 t ha-1. The harvester used was of one line, operating in three shift speeds, V1 (3.0 km h-1), V2 (5.0 km h-1), and V3 (7.0 km h-1). Two rotations of the primary extractor were used, the R1 of 700 rpm and R2 of 1000 rpm. Fuel consumption was evaluated by using flowmeters as well as its performance. The effective field capacity (ha h-1) and the actual time fuel consumption (L h-1) were greater increasing traveling speed and rotation. Increased harvester travel speed decreased fuel consumption per ton of sugarcane harvested (L t-1).KEYWORDS: Performance; operating efficiency; evaluation; mechanization.

Este trabalho investiga o uso de Redes Neurais Artificiais (RNAs) na análise da influência de fatores ambientais em diversos parâmetros fisiológicos em frangos de corte. Os dados deste trabalho foram obtidos em câmara climática do Núcleo de Pesquisa em Ambiência - NUPEA/ESALQ/USP. Machos e fêmeas de frangos de corte da linhagem Ross com 21, 28, 35, 42 e 49 dias de idade foram submetidos a quatro combinações de temperatura e umidade relativas. As RNAs foram utilizadas para avaliação da influência e relação de variáveis tais como temperatura, umidade relativa, frequência respiratória, temperatura retal, idade, ganho de peso, tempo de permanência no comedouro e tempo de permanência no bebedouro. Os resultados mostraram que é difícil predizer a condição ambiental a qual o animal foi submetido pelo conjunto de dados. O menor erro foi obtido com a variável ganho de peso como saída, sugerindo que esta seja a mais fortemente correlacionada com as outras variáveis.PALAVRAS-CHAVE: Redes Neurais Artificiais, avicultura, ambiência. STUDY OF THE INFLUENCE OF ENVIRONMENTAL FACTORS IN BROILER USING ARTIFICIAL NEURAL NETWORKSABSTRACT: This work investigates the use of Artificial Neural Networks to analyse the influence of ambiental variables in broilers.

Published: March 2018

O presente trabalho teve como objetivo realizar a análise temporal da cobertura vegetal, num período de 10 anos do município de Itaberá-SP, utilizando os índices de vegetação NDVI e NDWI por meio de imagens de satélite. Do ano de 2005 foram utilizadas duas imagens do Landsat 5 de órbita/ponto 221/76 e 221/77 e uma imagem de 2015 do Landsat 8, órbita/ponto 221/76. As bandas espectrais utilizadas foram: 3,4 e 5 do Landsat 5 e 4,5 e 6 do Landsat 8 que correspondem aos comprimentos de ondas do vermelho (RED), infravermelho próximo (NIR) e infravermelho médio (SWIR1), respectivamente. Através das análises dos índices, constatou que as áreas que possuem baixos valores de NDVI também possuem baixos valores de NDWI, o que indica uma vegetação que sofre estresse hídrico e com baixo teor de clorofila. Os valores mais altos indicam vegetação fotossinteticamente ativa, que contêm maior teor de umidade.PALAVRAS-CHAVE: Sensoriamento remoto, processamento de imagens, cobertura vegetal. TEMPORAL ANALYSISUSING VEGETATION INDEX OF VEGETATION COVER IN ITABERA (SP)ABSTRACT: The objective of this work was to carry out the temporal analysis of the vegetation cover, in a period of 10 years of Itaberá-SP county, making use of the vegetation index NDVI and NDWI of satellites images. Two Landsat 5’s images of 2005 with path/row 221/76 and 221/77 and one Landsat 8’s image, path/row 221/76 were used. The spectral bands used ware: 3, 4 and 5 of the Landsat 5 and 4, 5 and 6 of the Landsat 8 that correspond to red waves lengths (RED), near infrared (NIR) and medium infrared (SWIR1), respectively. It was found that areas with low NDVI values also have low NDWI values, indicating vegetation water stress and low chlorophyll contents. The highest values indicate Photosynthetically active vegetation, which contain higher moisture contents.KEYWORDS: Remote sensing, images processing, vegetal cover.

O objetivo do trabalho foi avaliar a prensagem a frio a partir das amêndoas de girassol alto oleico (AO) para obtenção de óleo extra virgem, biodiesel etílico e farinha proteica. A caracterização química foi realizada utilizando métodos oficiais de análise. O óleo foi extraído utilizando uma prensa helicoidal contínua e obteve-se um rendimento de 40%. O biodiesel etílico foi produzido por reação de transesterificação obtendo-se alto teor de ésteres etílicos (99,2%). Com a remoção total das cascas foi possível produzir um farelo com elevado teor de proteínas (51,6% b.s.). A composição mineral dos grãos, das amêndoas e das cascas de girassol mostrou que nos grãos os elementos de maior incidência foram Fe, Cr e Ni; nas amêndoas S, P, Mg, Cu, Mn e Zn e nas cascas Ca, K, Al, Ba, Sr e Na. Todos parâmetros de qualidade avaliados para o óleo, farinha e biodiesel etílico estão de acordo com a legislação indicando alta qualidade do óleo extra virgem e estabilidade termo-oxidativa, não sendo necessário o seu refino. A prensagem a frio das amêndoas, com ausência total de cascas, permitiu obter coprodutos de alta qualidade para aplicação na indústria alimentícia (óleo extra virgem e farinha proteica) e energética sustentável (cascas e biodiesel).PALAVRAS-CHAVE: Helianthus annuus L., estabilidade termo-oxidativa, composição química, minerais, transesterificação. OBTAINING OIL, FLOUR AND ETHYLIC BIODIESEL FROM COLD PRESSING OF HIGH OLEIC SUNFLOWER KERNELSABSTRACT: The objective of this work was to evaluate the cold pressing from high oleic (HO) sunflower kernels to obtain extra virgin oil, ethylic biodiesel and protein flour. The chemical characterization was performed using official methods of analysis. The oil was extracted using a continuous screw press and the yield was 40%. Ethylic biodiesel was produced by transesterification reaction obtaining a high content of ethyl esters (99.2%). With the total removal of the hulls, it was possible to produce a meal with 51.6% proteins. The mineral composition of the grains, kernels and hulls showed that in the grains the elements of higher incidence were Fe, Cr and Ni; in the kernel were S, P, Mg, Cu, Mn and Zn and in the hulls were Ca, K, Al, Ba, Sr and Na. All quality parameters evaluated for oil, flour and ethylic biodiesel were in accordance with the legislation and indicated high quality and thermo-oxidative stability in extra virgin oil, with no necessity of refining. The removal of the hulls and the cold pressing of the kernels provide the production of high quality co-products for use in the food industry (extra virgin oil and protein flour) and sustainable energy (hulls and biodiesel).KEYWORDS: Helianthus annuus L., oxidative stability, chemical composition, minerals, transesterification.

Authors: Buendía Arias Ximena Paoa , Zambrano Castillo Lilian Cecilia , Insuasty Edgar Alirio
Published: March 2018

Este artículo da cuenta de los resultados de un estudio que tuvo como propósito determinar hasta qué punto los siete programas académicos de la Facultad de Educación fomentan el desarrollo de competencias investigativas en el contexto de la práctica profesional pedagógica. La recolección de la información se hizo con base en un enfoque cualitativo-descriptivo por medio de encuestas, cuestionarios, entrevistas y análisis de documentos. La técnica utilizada para analizar la información recolectada a travésde estos instrumentos fue el análisis de contenido. Los principales hallazgos son la ausencia de un desarrollo balanceado de las competencias investigativas que fueron exploradas en este estudio, así como la falta de articulación entre la práctica pedagógicay la investigación. Adicionalmente, en este estudio se resalta la reconceptualización de la práctica pedagógica como un espacio para la reflexión y la investigación.
Creencias epistemológicas de docentes de matemáticas en formación y en ejercicio sobre las matemáticas, su enseñanza y aprendizaje
Authors: Vesga Bravo Grace Judith , De Losada Mary Falk
Published: March 2018

En este artículo se presenta el resultado de una investigación que tuvo como objetivo analizar y describir las creencias epistemológicas de seis docentes de matemáticas en formación y tres docentes en ejercicio sobre las matemáticas, su enseñanza y aprendizaje, comprender cómo se estructuraron y cómo se transforman. Se utilizó una metodología con enfoque cualitativo, a través de estudios de casos; los participantes asistieron a cursos orientados a desafiar sus creencias epistemológicas y a promover reflexión al respecto. Se usaron como instrumentos cuestionarios cerrados y entrevistas semiestructuradas. Se pudo identificar que es la experiencia docente intensiva la que permite crear y consolidar creencias epistemológicas, que el pregrado constituye una etapa en la que las creencias epistemológicas formadas con anterioridad en el colegio se están ajustando permanentemente, y que la formación recibida, tanto implícita como explícita, es de difícil y lenta asimilación. También, se pudo establecer que las creencias epistemológicas de docentes en formación y en ejercicio están en constante confrontación. Esto posibilita que los programas de formación, inicial o continua, incidan de manera más efectiva y explícita en su construcción o transformación. Por último, se plantean elementos que se deben considerar en los programas de formación, encaminados a lograr creencias de acuerdo con los fines de la educación matemá tica.
Matemáticas para todos en tiempos de la inclusión como imperativo. Un estudio sobre el programa Todos a Aprender
Authors: Garcia Oliveros Gloria , Romero Rey Julio Hernando
Published: March 2018

En este artículo, con referentes de Thomas Popkewitz, se analiza la problemática de la equidad, específicamente las estrategias de inclusión mediante la administración social y normalización de los Derechos Básicos de Aprendizaje (DBA) de las matemáticas que operan el principio “Matemáticas para todos”. Se realiza el análisis documental en torno a tres problemáticas ligadas a la inclusión de todos: (1) las relaciones entre administración social del Estado, educación matemática y equidad; (2) la investigación en educación matemática que se ha ocupado de la problemática de equidad e inclusión; y (3) los aparatos de administración y mecanismos de regulación de prácticas de aprendizaje de las matemáticas inclusivas. El análisis se realizó sobre dos tipos de documentos, los del campo de investigación en educación matemática y de políticas nacionales y estudios internacionales, y los de materiales curriculares y técnicas de evaluación. El análisis posibilitó concluir que la gestión de estrategias de inclusión de los DBA sigue considerando que el aprendizaje es monolítico y la gestión de homogenización del aprendizaje allí promovido vuelve a reforzar la exclusión. A partir de este análisis nos interrogamos acerca de con qué políticas del conocimiento queremos incluir a todos los estudiantes para que aprendan matemáticas.

Optimalisasi sistem pemberdayaan wakaf produktif sebagai alternatif sumber ekonomi umat
Authors: Suratmin Muh. Shaleh
Published: March 2018

Wakaf is one of the main religious service which contains productive economic values but in reality thevalues haven’t fully been implemented. The most important factor of this is the lack of socialization and the minimum role of the government (Badan Wakaf Indonesia). The enactment of the new wakaf bill (UU No. 41/2004) which followed by Peraturan Pemerintah Nomor 42 Tahun 2006 has not effective yet. How to maximize waqf advantages for society empowerment? This is the focus of study. The result of study shows that wakaf is very important to be the source of capital for empowering umat’s economy. The way to understand (fiqh) wakaf must be reformulated. The maximization of productive wakaf needs proper public understanding and good management. That is why that the nadhir must fulfill moral, managerial, and entrepreneur qualifications. The writer conclude that only trough revitalizing the role of BWI and the public awareness, the new paradigm of waqf can be realized in Indonesia.
La unificación del derecho comercial internacional: nueva lex mercatoria como alternativa al derecho estatal
Authors: Cándano Pérez Mabel
Published: March 2018

La nueva lex mercatoria ha alcanzado un lugar en la unificación del derecho comercial internacional, para convenir la forma más justa de dirimir los conflictos entre comerciantes. Esto se refleja en un marco normativo conocido como los Principios de UNIDROIT, a pesar de la existencia de ordenamientos jurídicos en todo el mundo. En este artículo se analiza, a partir de las nuevas tendencias en el comercio internacional, las ventajas que trae consigo la figura de la lex mercatoria, como una alternativa al derecho estatal. En especial, se intenta exponer, a través de una metodología analítica, las causas, la naturaleza y los efectos de los Principios de UNIDROIT para los contratos internacionales. En consecuencia, se concluye que la concepción de esta figura se fundamenta en una elaboración detallada de un codificador privado, con términos flexibles, y su aplicación no está al margen de la intervención jurisdiccional de los Estados.
Alcance normativo del régimen de protección al consumidor de los servicios de salud
Authors: Pérez Forero Andrea Carolina
Published: March 2018

Con sustento en el rediseño que tuvo la prestación de los servicios de salud a partir de una visión económica de los mismos y las consecuencias que ello acarrea; el presente escrito expondrá si en efecto existe un régimen más garantista de los derechos que como consumidor detenta quien es usuario de los servicios de salud, a quien a falta de regulación en el estatuto general, por vía de otras alternativas, se le han salvaguardado todas sus facultades; en comparación con la regulación ofrecida para los consumidores de otro tipo de servicios. Para ello y a través de una metodología teórica de corte analítico, se identificará la afinidad y disparidad normativa, determinándose que en la actualidad coexisten regímenes que se complementan en procura del bienestar de los pacientes-consumidores.
Algunos problemas “públicos” de la contratación estatal en Colombia como componentes del enfoque de ciclo para la formulación de una política pública
Authors: Vásquez Santamaría Jorge Eduardo
Published: March 2018

A partir de la pregunta ¿qué problemas públicos, alternativas de solución y procesos consensuados de toma de decisiones desde el enfoque de ciclo hacen posible una política pública para la planeación de la contratación en la Gobernación de Antioquia? el artículo trabaja el problema público como componente inicial del enfoque de ciclo, que en este caso se emplea para exponer deficiencias en la planeación de la contratación estatal y definir cuáles de ellas son problemas públicos para una política pública. Frente a estos objetivos se aplicó un diseño metodológico basado en el modelo cualitativo, con enfoque descriptivo orientado por categorías predefinidas. Como problemas públicos se exponen y definen la indeterminación del principio de planeación, la desatención de la ley 80/1993 a la teoría económica, la incompletitud del contrato estatal, la restricción de la subasta como mecanismo únicamente aplicable para la contratación de bienes y servicios de características uniformes y de común utilización en la contratación abreviada, y la exclusión normativa de entidades estatales de la ley 80/1993.
Cell Averaging CFAR Detector with Scale Factor Correction through the Method of Moments for the Log-Normal Distribution
Authors: Machado Fernández José Raúl , Bacallao Vidal Jesús De la Concepción
Published: March 2018

Se presenta el nuevo detector LN-MoM-CA-CFAR que tiene una desviación reducida en la tasa de probabilidad de falsa alarma operacional con respecto al valor concebido de diseño. La solución corrige un problema fundamental de los procesadores CFAR que ha sido ignorado en múltiples desarrollos. En efecto, la mayoría de los esquemas previamente propuestos tratan con los cambios bruscos del nivel del clutter mientras que la presente solución corrige los cambios lentos estadísticos de la señal de fondo. Se ha demostrado que estos tienen una influencia marcada en la selección del factor de ajuste multiplicativo CFAR, y consecuentemente en el mantenimiento de la probabilidad de falsa alarma. Los autores aprovecharon la alta precisión que se alcanza en la estimación del parámetro de forma Log-Normal con el MoM, y la amplia aplicación de esta distribución en la modelación del clutter, para crear una arquitectura que ofrece resultados precisos y con bajo costo computacional. Luego de un procesamiento intensivo de 100 millones de muestras Log-Normal, se creó un esquema que, mejorando el desempeño del clásico CA-CFAR a través de la corrección continua de su factor de ajuste, opera con una excelente estabilidad alcanzando una desviación de solamente 0,2884 % para la probabilidad de falsa alarma de 0,01.
Governança desportiva: uma inflexão da governança global?
Authors: Pizarro Juliano Oliveira
Published: March 2018

Es a partir de la percepción de la llamada gobernanza global que parte la investigación actual, donde hay espacio para el surgimiento de diferentes actores que realizan gobernanzas específicas– incluyendo en este escenario el deporte y especialmente el fútbol como un mecanismo social y cultural importante, que es directamente afectada por los procesos de globalización. La investigación se basa en fuentes bibliográficas, documentales, sitios web e investigaciones ya realizadas sobre el objeto. Se observó que los órganos de gobierno deportivos, en especial la FIFA, son organizaciones no gubernamentales que se presentan como instituciones sin fines de lucro, a pesar del comportamiento que oscile a veces como mercado, expresando características híbridas y contradictorias en la dinámica de la gobernanza global, ora como una multinacional, ora como una organización del Tercer Sector, ora como una institución internacional.
Role of Rhizobium in chickpea (Cicer arietinum) production - A review
Authors: Singh Zorawar , Singh Guriqbal , Saravaiya S. N.
Published: March 2018

Vegetables are nutritionally rich, high-valued crops and remunerative enough to replace subsistence farming. However, vegetables are highly sensitive to climatic vagaries and sudden irregularities in weather factors at any phase of crop growth can affect the normal growth, flowering, fruit development and subsequently the yield. Grafting in vegetable has emerged as a promising surgical alternative over relatively slow conventional breeding methods aimed at increasing tolerance to biotic and abiotic stresses. It provides an opportunity to transfer some genetic variations of specific traits of rootstocks to influence the phenotype of scion. Thus, genetic potential of various rootstocks in vegetable crops has proven to be a better alternative to chemical sterilants against many soil-borne diseases. The higher physiological activities like antioxidant content, lipoxygenase activity, osmotic adjustment, membrane selectivity, development of adventitious root and aerenchymatous tissue in plants grafted onto potential rootstocks provide broad insight into stress response mechanisms and thus, grafting is proposed to mitigate the adverse impact of climate change on productivity and quality of vegetables crops.
Plant growth promoting rhizobacteria and Rhizobium combinations are the key to reduce dependence on phosphorus fertilizers in lentil - A review

Improved agricultural technologies are helping in meeting the foodgrain needs of growing global population while the arable land is shrinking. So, the excessive and continuous use of chemical fertilizers has ensured the high crop production and productivity of foodgrains. However, continuous application of inorganic fertilizers has created many problems related to biosphere i.e. environmental, soil and human being. In recent years, the scientists are concerned about biosphere hazardous; thus, reducing the extra burden of inorganic fertilizers by using microbial inoculants for integrated nutrient management. The microbial inoculations supplement the plant growth and yield by direct ways (increase in supply of nutrients i.e. nitrogen, production of metabolites such as auxins, cytokinins and gibberellins as well as through the solubilization of phosphate and other minerals) and indirect ways (biofertilizers eliminate the pathogens by the production of cyanide, siderophores, chitinase etc.). The microbial inoculation stimulates the plant to use applied as well as fixed nutrients i.e. phosphate efficiently, thus helps to reduce the fertilizers input. Secondly, biofertilizers are considered as economically feasible and environmentally safe.

The land evaluation for enhancing ground nut (Arachis hypogaea L.) production in Pulivendula tehsil, Kadapa district was carried out as per FAO approach using soil map with 43 mapping units generated on 1:25000 scale and GIS technology to build thematic maps of suitable land units for peanut production with agroeconomic analysis. The land suitability analysis showed that 42.08 per cent of total cropped area is moderately suitable over current area of 14.8 per cent. with limitation of salinity, rooting depth, surface stoniness, gravelliness and soil texture. The economic evaluation for each soil mapping unit showed that only Pulivendula series has recorded benefit cost ratio more than 2 but in others this ratio is less 1.Results of landuse analysis suggested that participatory and bottom-up approaches are needed to understand the problems and opportunities in household agricultural production in order to develop appropriate landuse plans.

Published: March 2018

Information Communication Technologies have greatly impacted the education sector over the years leading to electronic service delivery. Universities all over the world are embracing Information Communication Technologies especially the internet, creating websites, making use of web 2.0 applications, that is, social networks and moving their services from manual based to electronic platforms. The study was comparative, looking extent to which the National University of Science and Technology (NUST) (Zimbabwe) and the University of Venda (RSA) have embraced ICTs in the conduct of business and how this has impacted on their service delivery.  Universities have embraced ICTs in different levels, according to their capacity in terms of finances, human resources, institutional capacity and other variables. A combination of web content analysis and a comparative study of the web presence of the two universities was done which revealed that the universities are present on some web 2.0 applications though not fully exploiting all the functions. Websites for both universities were carefully analysed and the results showed that online service delivery was growing yet in need of full implementation and use. It is therefore recommended that these universities adopt online service delivery to    enhance and develop lives of the university community.

Authors: Kapici Hasan Ozgur , Akcay Hakan
Published: March 2018

Learning in laboratories for students is not only crucial for conceptual understanding but also contributes to gaining scientific reasoning skills. Following fast developments in technology, online laboratory environments have been improved considerably and nowadays form an attractive alternative for hands-on laboratories. The study was done in order to reveal pre- service science teachersâ€™ preferences for hands-on or online laboratory environments. Participants of the study were 41 pre-service science teachers who were enrolled in a 13 weeks course on Laboratory Applications in Science Education. Findings showed that more than half of pre-service science teachers would like to prefer to use hands-on laboratory environments for both conceptual teaching in their classrooms and to develop their studentsâ€™ science process skills. The reasons behind their choices are discussed.
De la presencialidad a la distancia: modelos para la incorporación del e-learning en la universidad
Authors: Grünberg Jorge , Armellini Alejandro
Published: March 2018

Este artículo discute un marco de referencia para la conceptualización y evaluación de modelos de e-learning en educación superior. Las modalidades "presencial" y "a distancia" han sido concebidas históricamente como los modelos educativos por excelencia conceptualizados como mutuamente contrapuestos. Sin embargo, las tecnologías de e-learning, posibilitan nuevos modelos educativos que combinan la presencialidad y la distancia de distintas maneras. Sobre la base de la experiencia de la Universidad ORT Uruguay, planteamos un continuo a lo largo del cual aparecen modelos educativos en los que el e-learning y el aula presencial se complementan para lograr distintos objetivos. Las dimensiones pedagógicas, tecnológicas y económicas de estos modelos son abordadas en este artículo.
Prácticas con tecnologías
Authors: Litwin Edith
Published: March 2018

El estudio de las prácticas de la enseñanza puede realizarse mediante tres enfoques diferentes: el de docentes que planean la clase, desde la perspectiva de los estudios didácticos de la década del 50 y del 60 y que pusieron énfasis en la preparación de la clase; el del estudio de los procesos reflexivos que realiza el docente una vez acontecida la clase, especialmente en la década del 70 y el 80; y el de los estudios que analizan las acciones espontáneas de los docentes en las clases, sus intuiciones, la sabiduría práctica. El artículo parte de este análisis para reconocer cómo los docentes incluyen las tecnologías en las aulas, adoptan criterios diferentes para su uso o para su reutilización. Diferencia las tecnologías creadas para las tareas docentes, de las utilizadas por el docente pero que fueron creadas para otros fines. Distingue tanto los usos silenciosos de las propuestas didácticas por una revalorización del medio, como los de una tecnología negada cuando se ignora el mensaje que trasmite y se la utiliza para promover procesos de pensamiento. También se identifican situaciones en que se potencian las propuestas pedagógicas o que, por el contrario se las banaliza a partir de estas introducciones. Finalmente, se reconoce que las prácticas con tecnologías están implicadas en las propuestas didácticas y, por tanto, en las maneras en que se promueve la reflexión en el aula, se abre un espacio comunicacional que permite la construcción del conocimiento y se genera un ámbito de respeto y ayuda en los difíciles y complejos problemas de enseñar y aprender.
Poverty Eradication in Nigeria: A Focus on National Poverty Eradication Programme in Abia State, 2001- 2013
Authors: Eleagu Greene Ifeanyi
Published: March 2018

Poverty has been a huge challenge to Nigeria for a long time as majority of Nigerians live below poverty line. Successive civilian and military governments in Nigeria agreed on the need to eradicate or alleviate this ugly situation. In an attempt to ameliorate the situation, they introduced a number of schemes and programmes. The apparent failure of the various schemes and programmes and the resultant citizen discontent led to the creation of the National Poverty Eradication Programme, NAPEP, in all the states of the federation and the Federal Capital Territory. The broad objective of the study was to empirically evaluate the impact of NAPEP towards poverty eradication in Abia state, through the provision of youth employment. The structuralfunctionalist theory was adopted with an interrogation of relevant documents on financial flows, projects and programmes. The findings suggest that youth unemployment was pervasive. Again, the poverty reduction or alleviation efforts were fraught with corruption. To correct these, the work recommended disbursing monies to beneficiaries through banks. It also suggested, among others, that future efforts should be rural-centred, instead of urban-centred.

Exploring How Emotional Intelligence Contributes to Virtual Teams: Interpretive Analysis of a Phenomenological Study
Authors: Quisenberry William L.
Published: March 2018

The use of virtual teams continues to rise due to various factors such as increased pressure from competing forces, globalization, the need for improved efficiency, and technological advances. Despite the various benefits associated with high performing virtual teams, these specialized groups also experience extremely high failure rates. The increased failure can come as a result of various challenges including a lack of knowledge-sharing, limited communication, team members who lack self-managed and virtual teaming experience, and social loafing. While increased challenges are prevalent during virtual teaming arrangements, there seems to be evidence supporting that virtual team performance can be improved when team members have higher emotional quotients. This paper explores the potential benefits of emotionally intelligent virtual team members to understand how those with higher emotional quotients can potentially improve project success. The research involved analyzing a phenomenological study that interviewed 31 self-managed virtual team members via electronic questionnaires and surveys. This study follows up the original empirical research with an interpretative analytical review of the phenomenological findings pertaining to emotional intelligence and virtual teams. A thorough discussion regarding the findings and recommendations are provided.

Published: March 2018

This paper focuses on contributing to the formation of future professionals of agriculture from a different perspective. As a result, the theoretical, empirical, and statistical analysis methods were used according to the research. These methods deal with the ecological worldwide problems such as; climatic change, greenhouse effect, global warming, water crisis, and, at the same time, how agriculture is affected by those problems. The use of various techniques and predators methods of production has contributed in worsening the situation. Alternative methods were presented to reduce the negative effect of agriculture on the ecosystems. This, therefore, would help to finally offer a didactic, dynamic, and participative model for the training of professionals through university - society relationship.
