    O segmento de confeitos em geral, onde se destacam as balas, está muito presente no cenário brasileiro e mundial. As indústrias vêm constantemente aprimorando seus produtos com a incorporação de novos ingredientes e tecnologias, para atender principalmente as necessidades exigidas pelos consumidores, que estão cada vez mais exigentes em relação à qualidade do produto a ser consumido. Com base nesta premissa e vislumbrando atender esta nova tendência de mercado a proposta deste trabalho foi o desenvolvimento de uma bala mastigável adicionada de inulina. A inulina é um carboidrato (frutano que não é digerido no trato gastro-intestinal superior do ser humano, e exerce efeito bifidogênico, estimulando o crescimento e/ou a atividade das bactérias benéficas do cólon, ajudando na manutenção da fl ora intestinal e prevenção do câncer (prebiótico. Foram desenvolvidas duas formulações de balas mastigáveis, com e sem inulina na composição. Realizaram- se análises microbiológicas, físico-químicas e análise sensorial. As amostras analisadas adequaram-se à legislação brasileira nos parâmetros físico-químicos e microbiológicos avaliados e, quanto à análise sensorial, observou-se boa aceitação do produto. A adição de inulina à formulação trouxe uma variação significativa no atributo textura, tendo um aumento na maciez do produto final.

    Full Text Available The D-eigenvalues μ1,μ2,…,μn of a graph G of order n are the eigenvalues of its distance matrix D and form the distance spectrum or D-spectrum of G denoted by SpecD(G. Let G1 and G2 be two regular graphs. The Indu–Bala product of G1 and G2 is denoted by G1▾G2 and is obtained from two disjoint copies of the join G1∨G2 of G1 and G2 by joining the corresponding vertices in the two copies of G2. In this paper we obtain the distance spectrum of G1▾G2 in terms of the adjacency spectra of G1 and G2. We use this result to obtain a new class of distance equienergetic graphs of diameter 3. We also prove that the class of graphs Kn¯▾Kn+1¯ has integral distance spectrum.

    Full Text Available The BaLa2-xCexTi3O10 samples (with x = 0.2, 0.4, 0.6 and 0.8 were prepared by hydroxide co-precipitation method and finally sintered at 1150 °C. The structure of the prepared samples was characterized by XRD and SEM. The single phase material was confirmed only for the BaLa1.8Ce0.2Ti3O10 ceramics. However, at higher cerium concentration secondary phase was observed. The characteristic plate-like structure, having grains with submicrometer thickness and high aspect ratio, was clearly observed by SEM. The results of dielectric measurement suggest that the appropriate adjustment of doping (with x between 0.2 and 0.8 will give sufficient high dielectric constant at very low loss. The resistivity of samples decreases with increase in temperature indicating the normal semiconducting electrical behaviour.

    Full Text Available O estudo teve como objetivo verificar a estabilidade das vitaminas A, C e E, na forma de acetato de vitamina A, ácido ascórbico e acetato de vitamina E, sobredosadas em 80%, 80% e 50% respectivamente na fortificação de confeitos do tipo balas de gelatina, fornecendo 30% da IDR destas vitaminas em 100 g de produto. As vitaminas adicionadas não afetaram a qualidade das gomas de gelatina em relação à textura e claridade, parâmetros estes avaliados após processamento. Houve uma perda média no processamento de vitamina A de 25% em relação ao adicionado, seguida da vitamina E com 12% e vitamina C com 1%. Aumentando-se a temperatura de depósito da calda das gomas, de 70ºC para 80ºC encontrou-se uma diminuição na concentração da vitamina A de aproximadamente 37% e de 9% para a vitamina C. A eliminação do ácido cítrico da formulação das gomas com o propósito de minimizar perdas no processo não foi benéfica para as vitaminas C e E. Na estocagem de 6 meses obteve-se uma queda média de 93% da vitamina A, 57% para a vitamina C e 24% da vitamina E. Verificou-se, portanto que as vitaminas A e C irão ditar a vida de prateleira das gomas de gelatina e não foram sobredosadas em concentrações suficientes para garantir o declarado no rótulo até 6 meses numa estocagem controlada a 20ºC.This study had as objective to verify the stability of vitamins A, C and E, in the form of vitamin A acetate, ascorbic acid and vitamin E acetate, with overages at 80%, 80% and 50% respectively in gelatine gums confectionery type, supplying 30% of RDI of these vitamins in 100 g product. The added vitamins did not affect the quality of gelatine gums in relation to the texture and clarity, which were analyzed after processing; however, the gums with vitamins became brown with shelf life, being vitamin C the responsible for the presented defect. There were an average loss of vitamin A of 25% in relation to the initially added, followed by vitamin E

    Full Text Available Nef’i is one of the most powerful ode and satirical poet of Divan literature. He had used all the details of hyperbolisim in his poems. He had used the hyperbolisim by using the power of poetry but at the same time he had not disturb the imagination of the readers while using the hyperbolisim. In order to lighten the mood of hyperbole he always left some doors open. Greatness of sultans are explained in the hyperbolisim related tothe parise of the sultans. Love towards the horses is not an ordinarybare love. He uses horse as an image by giving different meanings. Inhis satires he criticizes in a strong way just the opposite of hispraisings. The explanation of cosmic universe gives chance to explainthe ideas in an indirect way. In the odes of Nef-i the realities areexplained in degrees. In order to understand the meaning of his words,these degrees should be analised in detailes. He had resembled hiswords as an closed magazine. This feature also shows the walue of hisworks. In this ode Nef-i tries to Express the importance of the meaningof the words rather than the structures of the sentences.The poet sometimes sees himself as an diver who searches pear inthe sea of meaning. Sea symbolises the meaning of hugeness,greatness, foreverness. Sea represents the soul of poet and thinkingvisdom of poems. The poet had tried to explain his dream world whenhe had used the hyperbolisim in his poems. While he was exaggeratingthe events, he had tried to explain the hiden reality and he had alsotried to show the most extraordinarry events as ordinary tings.Theability of using hyperbolisim in his poems comes from this feature. Nef’i, Divan edebiyatının en güçlü kaside ve hiciv şairidir. Nef’i, kasidelerinde mübalağa sanatının bütün detaylarını işlemiştir. Şiirin üst dilinden yararlanarak mübalağa sanatını en iyi kullanan sanatçı, okuyucunun hayalini incitmemiştir. Şiirlerindeki aşırı abartıyı yumuşatmak için mutlaka bir a

    Full Text Available A produção integrada (PI vem suprir uma demanda crescente de frutos de qualidade, garantir segurança alimentar, produção com qualidade ambiental e rastreabilidade. Na visão da PI, as práticas da adubação e do controle de doenças estão intimamente relacionadas; no entanto, tem sido negligenciadas e pouco estudadas, principalmente para a doença "furo de bala" (Wilsonomyces carpophilus em folhas de ameixeira (Prunus salicina. O objetivo deste trabalho foi avaliar a incidência e severidade dessa doença em doses combinadas de adubação com N e K em dois ciclos de cultivo comercial de ameixeira cv "Reubennel", no município de Araucária (PR. Foram utilizadas cinco doses de N (40, 80, 120, 160 e 200kg ha-1ano-1 e duas de K (55 e 110kg ha-1ano-1. Realizaram-se sete avaliações para incidência e severidade a cada 20 dias, no período de novembro/2004 a março/2005 e em data única em outubro/2005. Os dados da primeira safra foram integralizados no tempo, constituindo a área abaixo da curva de progresso da doença (AACPD da incidência e severidade, e os dados foram analisados estatisticamente pela teoria dos modelos lineares generalizados para dados longitudinais. A doença foi mais severa no segundo ano de avaliação, sendo observado o máximo de 0,70 e 2,25 para o primeiro e o segundo ano, respectivamente. A incidência e a severidade de "furo de bala" em folhas de ameixeira são superiores nas doses de 160 e 200kg ha-1ano-1 de nitrogênio. O potássio não interfere na incidência e severidade da doença devido ao seu elevado teor encontrado no solo e na planta.Integrated Production (IP can provide the growing demand for quality fruit, food safety, environmental protection, and product traceability. In IP, fertilization practices and disease control are viewed as being closely related. However, this linkage has been mostly ignored and few studies are available concerning the 'shot hole' phytopathogen (Wilsonomyces carpophilus in

    Full Text Available The impact of community-based ecotourism is contingent upon the community’s involvement in the development and management of activities, as well as their access to and the comprehensiveness of benefits. The ecotourism business owned by the Tacana Indigenous community of San Miguel in the Bolivian Amazon provides a model as to how Indigenous communities can harness social entrepreneurship to address economic, social, and environmental challenges. This article reviews the origins and development of this business, and draws on participant observation research, interviews, surveys, and economic analysis to illustrate the lessons learned and challenges faced. The findings are presented to inform existing and new Indigenous tourism ventures, policy considerations, and future research.

    In this paper we analyze the effect of criminal violence on electoral participation in Mexico. Many scholars have studied the origins of criminal violence, as well as the success or failure of contemporary regimes in dealing with it. However, few have studied how it affects voter turnout. Following recent findings in the behavioral subfield, we hypothesize that as criminal violence increases, citizens abandon public channels of participation and take refuge in their private spheres.

    Full Text Available Efficient drug delivery systems are as important as drug themselves. A powerful drug unable to reach the target cell is useless in practice. Ehrlich's Magic Bullet was the first carrier system to be proposed. The evolution in this domain has been quite slow as the natural mechanisms of mammals against foreign products are hard to overcome. However, lipid-based systems (liposomes and related vesicles have attained reasonable success. The basic preparations and structural features of liposomes and related vesicles as well as their applications are addressed from the chemist's and biochemist's point of view.

    2006-01-01

    This map was produced from several larger digital datasets. Topography was derived from Shuttle Radar Topography Mission (SRTM) 85-meter digital data. Gaps in the original dataset were filled with data digitized from contours on 1:200,000-scale Soviet General Staff Sheets (1978-1997). Contours were generated by cubic convolution averaged over four pixels using TNTmips surface-modeling capabilities. Minor artifacts resulting from the auto-contouring technique are present. Streams were auto-generated from the SRTM data in TNTmips as flow paths. Flow paths were limited in number by their Horton value on a quadrangle-by-quadrangle basis. Peak elevations were averaged over an area measuring 85 m by 85 m (represented by one pixel), and they are slightly lower than the highest corresponding point on the ground. Cultural data were extracted from files downloaded from the Afghanistan Information Management Service (AIMS) Web site (http://www.aims.org.af). The AIMS files were originally derived from maps produced by the Afghanistan Geodesy and Cartography Head Office (AGCHO). Because cultural features were not derived from the SRTM base, they do not match it precisely. Province boundaries are not exactly located. This map is part of a series that includes a geologic map, a topographic map, a Landsat natural-color-image map, and a Landsat false-color-image map for the USGS/AGS (Afghan Geological Survey) quadrangles covering Afghanistan. The maps for any given quadrangle have the same open-file number but a different letter suffix, namely, -A, -B, -C, and -D for the geologic, topographic, Landsat natural-color, and Landsat false-color maps, respectively. The open-file report (OFR) numbers for each quadrangle range in sequence from 1092 - 1123. The present map series is to be followed by a second series, in which the geology is reinterpreted on the basis of analysis of remote-sensing data, limited fieldwork, and library research. The second series is to be produced by the USGS in cooperation with the AGS and AGCHO.

    Full Text Available Industries are technologically perfecting their products by adding new components, in order to meet the demands of consumers. The extraction of pulp from several tropical fruits for manufacture of bullets has been widely used, due to its nutritional and functional value. The aim this study was to develop an edible candy with the addition of passion fruit pulp adding nutritional value from natural ingredients. In order to carry out this study, fruits were purchased in the city of Sousa-PB, then sent to fruit processing sector located at IFPB Campus-Sousa, where the weighing process, sanitization in sodium hypochlorite solution was carried out 100ppm for 15 minutes, then the fruits were cut in half. The extraction was done manually, sieved for aryl separation. Soon after they were packed in plastic bags and sealed, a part sent to physicalchemical and microbiological analyzes and another frozen part to be used in elaboration of bullet. In process of bullet preparation (56.25% of sucrose, (37.5% glucose syrup and 6.25% of the passion fruit pulp were used. Microbiological and physical-chemical analyzes (moisture, ash, pH, acidity in citric acid, protein, soluble solids, flavonoids were performed in the pulp and afterwards, hygroscopicity and color were only performed on bullet. According to results obtained, pulp and passion fruit bullet presented physical-chemical and microbiological results as established by legislation. The addition of concentrated passion fruit pulp extract may be an alternative, making a differentiated product with higher added value nutritionally, offering consumers health benefits without addition of dyes and artificial preservatives.

    Full Text Available Our article considers a hitherto unpublished document of great ethnographic interest: the report written by an explorer hired by Basque entrepreneur Horacio Echevarrieta in 1921. The author details his journey in search of iron mines thought to exist in an area of the central Rif beyond the control of the Spanish colonial army. His account draws a vivid picture of the Protectorate in 1921, a hotbed of unscrupulous individuals: ambitious warlords, dishonest explorers, rogues, mining agents, spies and indigenous local people with different interests and degrees of acculturation. Our study analyses the colonial context and highlights the hybrid identities generated by the presence of European capital in the area.Publicamos en nuestro artículo un documento inédito de gran interés etnográfico: la memoria escrita en 1921 por un explorador a sueldo al servicio del empresario vasco Horacio Echevarrieta. El autor escribe una detallada síntesis de su viaje a la búsqueda de supuestas minas de hierro en una zona del Rif central fuera del control del Ejército colonial español. Esta memoria recoge, sin querer, una imagen vívida del Protectorado en 1921, todo un hervidero de individuos sin escrúpulos: militares ambiciosos, exploradores-embaucadores, pícaros, agentes de compañías mineras, espías e «indígenas» locales con diferentes intereses y grados de aculturación. Nuestro trabajo analiza este contexto colonial y destaca las identidades híbridas generadas por la presencia del capital europeo en la zona.

    Full Text Available Los comedores populares autogestionarios - CPA¹ tienen más de 35 años de existencia, desde 1978, a la cabeza de mujeres valerosas, en una Lima pobre, migrante y luchadora. Estas mujeres lucharon frente al Estado por derechos y reivindicaciones, como servicios básicos y políticas alimentarias. Las mujeres hicieron, de temas caseros, políticas públicas que lograron sostener, en gran medida, la crisis económica a fines de la década de 1980 e inicios de la de 1990, dando así muestras de organización a gran escala en un contexto sumamente difícil. En ese complicado panorama, convivieron con integrantes del grupo subversivo del Partido Comunista del Perú-Sendero Luminoso - PCP-SL, que incursionó en las barriadas para «profundizar las contradicciones» y aplicó, en nombre de la justicia, estrategias de guerra. La investigación rastrea las trayectorias de las exdirigentas de los CPA en el distrito limeño de El Agustino, y recoge sus testimonios sobre la violencia política que les tocó vivir entre 1978 y 1992² y sobre las problemáticas relaciones con el Estado.

    Full Text Available In this paper we analyze the effect of criminal violence on electoral participation in Mexico. Many scholars have studied the origins of criminal violence, as well as the success or failure of contemporary regimes in dealing with it. However, few have studied how it affects voter turnout. Following recent findings in the behavioral subfield, we hypothesize that as criminal violence increases, citizens abandon public channels of participation and take refuge in their private spheres. Using longitudinal and geostatistical tools to analyze Mexican municipalities in the last decade, we find that the level of electoral turnout is lower in the most violent regions of the country. In the final section, we use survey data to confirm that citizens exposed to high levels of criminal violence are less likely to vote.En este artículo, analizamos el efecto de la violencia criminal sobre la participación electoral en México. Muchos investigadores estudiaron las causas de la violencia criminal y la respuesta de los diferentes gobiernos frente a este problema. Sin embargo, pocos estudios analizan el impacto de la violencia criminal sobre la participación en las elecciones. Siguiendo algunos hallazgos recientes en la literatura de comportamiento político, argumentamos que cuando la violencia criminal aumenta, los ciudadanos abandonan espacios públicos de participación y se refugian en la esfera privada. Usando métodos geoestadísticos para analizar las municipalidades en México en la ultima década, demostramos que la participación electoral es más baja en las regiones más violentas del país. En la última sección, usamos datos de una encuesta reciente para confirmar que ciudadanos expuestos a niveles altos de criminalidad tienen menos probabilidades de votar.

    Full Text Available Cidade de Deus traz em si a história da construção do conjunto habitacional, cujo nome intitula o romance, e de sua transformação em uma das favelas mais violentas do Rio de Janeiro, por meio do entrecruzamento das histórias de Cabeleira, Bené, Zé Pequeno e Busca-Pé. Concebendo o romance, nos atos da escrita e da leitura, como uma enunciação (BENVENISTE, 1989a; 1989b; 1995a; 1995b entre autor e leitor, constituída por outras enunciações — entre narrador e narratário e entre personagens — a partir do "ato ficcional" (ISER, 2002 do autor, vamos nos guiar por essa tessitura de/entre histórias para rastrear o modo como Lins relaciona linguagem e violência.

    Full Text Available The self-managed people’s kitchens (CPA have more than thirty five years of existence since 1978. They are led by brave women who live in a poor, inmigrant and courageous Lima. They struggled with the state for their rights and demands for basic services and food policies. These women made home topics into declared public policies and were able to bear through the economic crisis of the 80s and part of the 90s, showing a highly effective way of organization in a very difficult period. In that very complex context they were able to get along with members of Sendero Luminoso (SL who entered the shanty towns to «exacerbate contradictions» and applied their war strategies in the name of «justice».This investigation traces the trajectories of former leaders of the CPAs from the district of El Agustino, and presents their testimonies on the political violence that they lived between 1978 and 1992, and on their difficult relations with the State. This coexistence produced a very complex texture of thin threads, where living in proximitywhile keeping distance from SL were part or a more complex process.

  14. Complementarity beyond physics Niels Bohr's parallels

    CERN Document Server

    Bala, Arun

    2017-01-01

    In this study Arun Bala examines the implications that Niels Bohr’s principle of complementarity holds for fields beyond physics. Bohr, one of the founding figures of modern quantum physics, argued that the principle of complementarity he proposed for understanding atomic processes has parallels in psychology, biology, and social science, as well as in Buddhist and Taoist thought. But Bohr failed to offer any explanation for why complementarity might extend beyond physics, and his claims have been widely rejected by scientists as empty speculation. Scientific scepticism has only been reinforced by the naïve enthusiasm of postmodern relativists and New Age intuitionists, who seize upon Bohr’s ideas to justify anti-realist and mystical positions. Arun Bala offers a detailed defence of Bohr’s claim that complementarity has far-reaching implications for the biological and social sciences, as well as for comparative philosophies of science, by explaining Bohr’s parallels as responses to the omnipresence...

  15. The discovery of Kerivoula krauensis (Chiroptera: Vespertilionidae in southern peninsular Thailand provides new information on the distribution and conservation status of this data deficient species

    Directory of Open Access Journals (Sweden)

    Bounsavane Douangboubpha

    2014-10-01

    Full Text Available In August 2013, an adult male Kerivoula krauensis was captured in a harp trap set in forest understorey in Bala Forest, Hala-Bala Wildlife Sanctuary, Narathiwat Province, Thailand. This is only the second locality recorded for the species, the first outside Malaysia, and represents a range extension of 254 km, northwards from Krau Wildlife Reserve, Malaysia. This discovery has important conservation implications suggesting that the species is more widespread than previously thought but also confirms previous findings that it appears to live in very low population densities as compared to other Kerivoula found in the same habitat. Information on its taxonomy, echolocation call, distribution and ecology is included. In addition, the new material from Thailand is briefly compared to other known species from the country

    2016-12-01

    Full Text Available One myth that is believed by people living in Duwet village is distress that threatens human beings from when they are born till the day they die. As one way to overcome the distress, people, especially those who are living in Duwet village, hold ritual called as tolak bala. One step in the ritual is self-cleaning oneself from distress or sukerta. In addition to the ritual is a masked puppet as a means of the ritual execution. Thus, this study aims at finding out the functions of the Ruwatan masked puppet. Functional-structural perspective was adopted in the study by implementing observation, interview, and documentation study techniques. Results show that masked puppet has a special function which is to serve as a means of Ruwatan that is specifically to obtain society participation in order to give spiritual support to the process of ritual as a whole tolak bala or distress expulsion process.

  10. Importance of Ayu Pareeksha for the Management of Diseases.

    Science.gov (United States)

    Agrawal, Monika; Byadgi, P S; Dwibedy, B K

    2017-01-01

    The word Ayurveda comes from the Sanskrit root Ayu which means span of life. The purpose of examination of Ayu is to obtain knowledge regarding longevity, residual span of life in diseased person and rate of the mortality. The purpose of Dashavidha Pariksha is to obtain knowledge regarding Dosha Bala (Vyadhi Bala), Bala (Rogibala) and Ayu of the patient as described in Charak Samhita . Commonly Ayu and Vaya are regarded as synonyms but they are not similar terms. Hence, description of Vaya and Ayu is separately mentioned in Charaka as well as Sushruta Samhita . Description exclusively on Ayu Pareeksha described in Charaka Viman Sthana, Charaka Chikitsasthana, Charaka Indriya Sthana and Charaka Shareer Sthana. In Indriya Sthana, Ayu Pariksha indicates the residual life-span of the diseased person and where as in Jaatisutriya Adhyaya in Shareer Sthana mentioned the characteristic properties of the child who is going to survive for longer period of time. In Sushruta Samhita, Ayu is classified into three broad headings namely Dhirghayu, Madhyamayu and Alpayu and explained the characteristic properties of all the three.

Early estimates, by electron microprobe sum deficit, suggested up to 4 wt% H2O in olivine-hosted basaltic andesite melt inclusions (MI) from pre-historic ET-6 tephra (Melson, 1982), and up to 7 wt% H2O in plagioclase and orthopyroxene-hosted dacitic MI from 1968 lapilli (Anderson, 1979). These high water contents are consistent with abundant hornblende phenocrysts in Arenal volcanics, but inconsistent with geochemical tracers such as 10Be and Ba/La that suggest a low flux of recycled material (and presumably water) from the subduction zone. In order to test these ideas, and provide the first direct measurements of water in mafic Arenal magmas, we have studied olivine-hosted MI from the prehistoric (900 yBP; Soto et al., 1998) ET3 tephra layer. MI range from andesitic (> 58% SiO2) to basaltic compositions ( 4 wt%) found here for Arenal basaltic MI support the semi-quantitative data from earlier studies, but are somewhat unexpected given predictions from slab tracers. Arenal water contents (4%) approach those of the 1995 eruption of Cerro Negro in Nicaragua (4-5 wt% in basaltic MI; Roggensack et al., 1997), despite the fact that the latter has Ba/La of > 100, while Arenal has Ba/La Journal of Geology; Melson, William G.

    Purpose: Many published studies have recently demonstrated the potential value of intravoxel incoherent motion (IVIM) analysis for disease evaluation. However, few have questioned its measurement repeatability/reproducibility when applied. The purpose of this study was to determine the short-term measurement repeatability of apparent diffusion coefficient ADC, true diffusion coefficient D, pseudodiffusion coefficient D* and perfusion fraction f, in head and neck squamous cell carcinoma (HNSCC) primary tumors and metastatic nodes. Methods: Ten patients with known HNSCC were examined twice using echo-planar DW-MRI with 12 b values (0 to 800 s/mm2) 1hour to 24 hours apart before radiation treatment. All patients were scanned with the customized radiation treatment immobilization devices to reduce motion artifacts and to improve image registration in repeat scans. Regions of interests were drawn in primary tumor and metastases node in each patient (Fig. 1). ADC and IVIM parameters D, D* and f were calculated by least squares data fitting. Short-term test–retest repeatability of ADC and IVIM parameters were assessed by measuring Bland–Altman limits of agreements (BA-LA). Results: Sixteen HNSCC lesions were assessed in 10 patients. Repeatability of perfusion-sensitive parameters, D* and f, in HNSCC lesions was poor (BA-LA: -144% to 88% and −57% to 96% for D* and f, respectively); a lesser extent was observed for the diffusion-sensitive parameters of ADC and D (BA-LA: −34% to 39% and −37% to 40%, for ADC and D, respectively) (Fig. 2). Conclusion: Poor repeatability of D*/f and good repeatability for ADC/D were observed in HNSCC primary tumors and metastatic nodes. Efforts should be made to improve the measurement repeatability of perfusion-sensitive IVIM parameters.

    Rice (Oryza sativa) varieties that are arsenate-tolerant (Bala) and -sensitive (Azucena) were used to conduct a transcriptome analysis of the response of rice seedlings to sodium arsenate (AsV) in hydroponic solution. RNA extracted from the roots of three replicate experiments of plants grown for 1 week in phosphate-free nutrient with or without 13.3 μM AsV was used to challenge the Affymetrix (52K) GeneChip Rice Genome array. A total of 576 probe sets were significantly up-regulated at least 2-fold in both varieties, whereas 622 were down-regulated. Ontological classification is presented. As expected, a large number of transcription factors, stress proteins, and transporters demonstrated differential expression. Striking is the lack of response of classic oxidative stress-responsive genes or phytochelatin synthases/synthatases. However, the large number of responses from genes involved in glutathione synthesis, metabolism, and transport suggests that glutathione conjugation and arsenate methylation may be important biochemical responses to arsenate challenge. In this report, no attempt is made to dissect differences in the response of the tolerant and sensitive variety, but analysis in a companion article will link gene expression to the known tolerance loci available in the Bala×Azucena mapping population.

O trabalho transcorreu de março a maio de 2011, de um universo de 110 escolas de Ensino Fundamental e Ensino Médio das redes municipal, estadual e privada de um município da região central do Estado do Rio Grande do Sul. Das 110 escolas, 104 (94,5% participaram da pesquisa e, destas, 28,8% possuíam cantina, sendo uma presença marcante nas escolas privadas. Das escolas que não possuíam cantina, 40,4% possuíam comércio informal, sendo a maioria formada por escolas do âmbito municipal. Nas cantinas, há maior oferta de salgados fritos e folhados, cachorros-quentes, pizzas, hambúrgueres, balas, chicletes e pirulitos, refrigerantes, sucos industrializados e água. Os alimentos mais vendidos são salgados fritos, assados, cachorros-quentes, balas, chocolates e refrigerantes, em todos os âmbitos. Em suma, pode-se concluir que nenhuma cantina escolar está totalmente adequada em relação à lei vigente; porém, as cantinas das escolas particulares apresentam resultados mais satisfatórios quando comparadas às dos outros âmbitos.

    Abstract Background In this contribution we present detailed distribution and abundance data for arthropod species identified during the BALA – Biodiversity of Arthropods from the Laurisilva of the Azores (1999-2004) and BALA2 projects (2010-2011) from 18 native forest fragments in seven of the nine Azorean islands (all excluding Graciosa and Corvo islands, which have no native forest left). New information Of the total 286 species identified, 81% were captured between 1999 and 2000, a period during which only 39% of all the samples were collected. On average, arthropod richness for each island increased by 10% during the time frame of these projects. The classes Arachnida, Chilopoda and Diplopoda represent the most remarkable cases of new island records, with more than 30% of the records being novelties. This study stresses the need to expand the approaches applied in these projects to other habitats in the Azores, and more importantly to other less surveyed taxonomic groups (e.g. Diptera and Hymenoptera). These steps are fundamental for getting a more accurate assessment of biodiversity in the archipelago. PMID:28174509

    The research to be done in the CACTUS research programme produces new process models and generates new knowledge about the influence of various contaminants on the runnability and the quality of paper. The generated information calls for an environment where it can be analysed and utilised. The goal of the project is to build a design environment for papermaking processes. The environment will be composed of a number of tools, all integrated together, that can be used in process design from preliminary concept screening through detailed simulation studies to the design and tuning of control systems. The design environment is based on the Balas and APMS simulation programmes developed at VTT. Balas is a general steady-state simulation package for chemical processes with emphasis on pulp and paper. Recent applications include the analysis of the influence of new drying techniques on the energy and water management of a paper mill and the evaluation of new paper machine and water treatment concepts. APMS (Advanced Pulp and Paper Mill Simulator) is a new flexible tool intended for fast modelling and efficient simulation of the dynamic performance the various unit processes in pulp and paper mill, or even of the whole integrated mill.

Vamos considerar dois joguinhos nos quais você tem que decidir entre duas possibilidades, baseando-se apenas nas suas impressões quanto aos possíveis riscos e vantagens: JOGO 1: Suponha duas possibilidades: A – Você tem 25% de chance de ganhar 30 mil reais e 75% de ganhar nada. B – Você tem 20% de chance de ganhar 45 mil reais e 80% de ganhar nada. E então, você escolheria a alternativa A ou B? Uma pesquisa sobre esse dilema foi publicada pelo Nobel em Economia Daniel Kahneman e seu colaborador Amos Tversky, num artigo de 1986. Eles mostraram que 42% das pessoas entrevistadas optaram pela alternativa A, enquanto 58% optaram por B. Analisando esses valores, vemos que nem mesmo com um teste estatístico rigoroso encontraríamos alguma diferença muito impressionante. Suas diferenças apenas sugerem uma pequena tendência mais conservadora por parte dos participantes. Isto porque a diferença de 5% entre A e B parece ser um risco razoável a se correr frente ao ganho de 15 mil reais. Ok, mas por hora coloquemos esse jogo de lado e vamos para um outro.

    In this study, the genetic mapping of the tolerance of root growth to 13.3 μM arsenate [As(V)] using the Bala×Azucena population is improved, and candidate genes for further study are identified. A remarkable three-gene model of tolerance is advanced, which appears to involve epistatic interaction between three major genes, two on chromosome 6 and one on chromosome 10. Any combination of two of these genes inherited from the tolerant parent leads to the plant having tolerance. Lists of potential positional candidate genes are presented. These are then refined using whole genome transcriptomics data and bioinformatics. Physiological evidence is also provided that genes related to phosphate transport are unlikely to be behind the genetic loci conferring tolerance. These results offer testable hypotheses for genes related to As(V) tolerance that might offer strategies for mitigating arsenic (As) accumulation in consumed rice. PMID:18453529

Esses movimentos consideram sua religião como o repositório de verdade absoluta, a fonte derradeira que legitima as leis humanas. Assim, conquanto sejam pós-seculares, ao mesmo tempo tentam transformar os princípios religiosos em agendas políticas. Com efeito, os militantes agem frequentemente de acordo com princípios políticos, procurando afirmar o primado de sua própria fé sobre a dos outros. Eles se movem dentro das sociedades contemporâneas em nome de uma teologia política radical. Os principais argumentos baseiam-se em dois estudos de caso: o Bodu Bala Sena no Sri Lanka e os movimentos para o Hindutva na Índia.

    Due to the increasing globalization of printing industry, remoting proofing will become the inevitable development trend. Cross-media color reproduction will occur in different color gamuts using remote proofing technologies, which usually leads to the problem of incompatible color gamut. In this paper, to achieve equivalent color reproduction between a monitor and a printer, a frequency-based spatial gamut mapping algorithm is proposed for decreasing the loss of visual color information. The design of algorithm is based on the contrast sensitivity functions (CSF), which exploited CSF spatial filter to preserve luminance of the high spatial frequencies and chrominance of the low frequencies. First we show a general framework for how to apply CSF spatial filter in retention of relevant visual information. Then we compare the proposed framework with HPMINDE, CUSP, Bala's algorithm. The psychophysical experimental results indicated the good performance of the proposed algorithm.

    Full Text Available O presente trabalho foi realizado com o objetivo de se avaliar o efeito da secagem nas propriedades físicas dos grãos de soja, e analisar as diferentes metodologias de determinação da massa específica aparente e da massa específica real. Além disso, avaliaramse a contração volumétrica dos grãos de soja durante a secagem e, ajustes de diferentes modelos matemáticos aos valores experimentais das propriedades analisadas, em função do teor de água. Com base nos resultados obtidos, concluiu-se que a redução do teor de água provoca diminuição linear da porosidade na faixa entre 0,31 e 0,15 (b.s. e aumento das massas específicas aparente e real. Além disso, os resultados obtidos para massa específica real e aparente, pelo método de determinação com base nos constituintes dos grãos de soja, apresentaram-se inferiores aos valores experimentais. Os modelos de BALA & WOODS [2] adaptado, RAHMAN, linear e exponencial são apropriados para descrição da contração volumétrica da massa de grãos de soja, enquanto o modelo de BALA & WOODS [2] adaptado é o mais apropriado para descrição da contração volumétrica unitária da soja.The present work was accomplished with the objective of evaluating the drying effect on soy grain physical properties and to analyze different methodologies for determining bulk density and specific gravity. Also, the soy grain shrinkage was evaluated during the drying and different mathematical models were fitted to the experimental data in order to analyze the properties in connection with their moisture content. Based on the obtained results it can be concluded that the reduction in the moisture content promotes the linear decrease in the porosity in the range from 0,31 to 0,15 (b.s. and increase of both the bulk density and specific gravity. Also the soy grain bulk density and specific gravity values found through the grain chemical composition were lower than the experimental data. The adapted

    Frost, Susan

    2010-01-01

    The first part of this talk will describe some of the exciting new next generation aircraft that NASA is proposing for the future. These aircraft are being designed to reduce aircraft fuel consumption and environmental impact. Reducing the aircraft weight is one approach that will be used to achieve these goals. A new control framework will be presented that enables lighter, more flexible aircraft to maintain aircraft handling qualities, while preventing the aircraft from exceeding structural load limits. The second part of the talk will give an overview of utility-scale wind turbines and their control. Results of collaboration with Dr. Balas will be presented, including new theory to adaptively control the turbine in the presence of structural modes, with the focus on the application of this theory to a high-fidelity simulation of a wind turbine.

    Spectra of ternary tungstates, niobates and tantalates (MeLa 2 WO 7 , La 3 TO 7 ; Me=Ba, Sr; T=Ta, Nb) related to the layered fluorite group are analyzed. The laser pumping and time resolved luminescence are used for selecting spectra of unequivalent centers. The symmetry of the first center is near to the distorted cubic one. The vibrational spectra of europium in Eu 3 NbO 7 and SrLa 2 WO 7 are due to the chain-like structure of niobates and to the net-like structure of tantalates. The stimulated emission of Nd 3+ in powders of BaLa 2 WO 7 and La 3 NbO 7 is observed at wavelengths of 1.07 and 1.063 μm, respectively

    The Pliocene and Quaternary Patagonian alkali basalts of southernmost South America can be divided into two groups. The "cratonic" basalts erupted in areas of Cenozoic plateau volcanism and continental sedimentation and show considerable variation in 87Sr/86Sr (0.70316 to 0.70512), 143Nd/144Nd (e{open}Nd) and 206Pb/204Pb, 207Pb/204Pb, and 208Pb/204Pb ratios (18.26 to 19.38, 15.53 to 15.68, and 38.30 to 39.23, respectively). These isotopic values are within the range of oceanic island basalts, as are the Ba/La, Ba/Nb, La/Nb, K/Rb, and Cs/Rb ratios of the "cratonic" basalts. In contrast, the "transitional" basalts, erupted along the western edge of the outcrop belt of the Pliocene and Quaternary plateau lavas in areas that were the locus of earlier Cenozoic Andean orogenic arc colcanism, have a much more restricted range of isotopic composition which can be approximated by 87Sr/86Sr=0.7039??0.0004, e{open}Nd, 206Pb/204Pb=18.60??0.08, 207Pb/204Pb=15.60??0.01, and 208Pb/204Pb=38.50??0.10. These isotopic values are similar to those of Andean orogenic are basalts and, compared to the "cratonic" basalts, are displaced to higher 87Sr/86Sr at a given 143Nd/144Nd and to higher 207Pb/204Pb at a given 208Pb/204Pb. The "transitional" basalts also have Ba/La, Ba/Nb, La/Nb, and Cs/Rb ratios higher than the "cratonic" and oceanic island basalts, although not as high as Andean orogenic are basalts. In contrast to the radiogenic isotopes, ??18O values for both groups of the Patagonian alkali basalts are indistinguishable and are more restricted than the range reported for Andean orogenic are basalts. Whole rock ??18O values calculated from mineral separates for both groups range from 5.3 to 6.5, while measured whole rock ??18O values range from 5.1 to 7.8. The trace element and isotopic data suggest that decreasing degrees of partial melting in association with lessened significance of subducted slabderived components are fundamental factors in the west to east transition from arc

    Central Anatolia is bounded in the north by the well-known north Anatolian fault system (NAFS) and on the south-southwest is bounded by the east Anatolian fault system (EAFS). The central area does not have major faults and acts as a single block moving westward. This region is not considered as seismically active as the NAFS or EAFS but the recent moderate-size Bala earthquakes (Ml=5.7, Ml= 5.5) on 20 and 27 December 2007 near the Tuz golu fault may be an indication of future seismic activity. In order to get a better picture of the crustal structure of this region we applied Coda Normalization method for the measurement of Qs-1 as a function of frequency for the frequencies 1.5, 3, 6, 8 Hz. 20 and 27 December 2007 Bala earthquakes (Ml magnitude 5.6 an 5.5) and their aftershocks recorded by the Keskin seismic array (International Monitoring System code BRTR) is analyzed in this study. Keskin seismic array has a small aperture circular design with 6 vertical short period and 1 broadband borehole seismometers. In addition, Multiple Lapse Time Window Analysis (MLTWA) method was applied to the data for the separation of intrinsic and scattering attenuation inm the region at the same frequencies. MLTWA method allowed a separation between the intrinsic attenuation and scattering attenuation. Preliminary results show a relatively low attenuation compared to western and eastern anatolia regions. This might be explained by the less seismicity in the region. A study of the regional and site attenuation of seismic waves of earthquakes in this area will contribute in predicting earthquake generated ground-motion and becomes vital in making decisions for earthquake regulations, building codes and to monitoring nuclear explosions.

    Full Text Available Abstract Background Meta-analysis of QTLs combines the results of several QTL detection studies and provides narrow confidence intervals for meta-QTLs, permitting easier positional candidate gene identification. It is usually applied to multiple mapping populations, but can be applied to one. Here, a meta-analysis of drought related QTLs in the Bala × Azucena mapping population compiles data from 13 experiments and 25 independent screens providing 1,650 individual QTLs separated into 5 trait categories; drought avoidance, plant height, plant biomass, leaf morphology and root traits. A heat map of the overlapping 1 LOD confidence intervals provides an overview of the distribution of QTLs. The programme BioMercator is then used to conduct a formal meta-analysis at example QTL clusters to illustrate the value of meta-analysis of QTLs in this population. Results The heat map graphically illustrates the genetic complexity of drought related traits in rice. QTLs can be linked to their physical position on the rice genome using Additional file 1 provided. Formal meta-analysis on chromosome 1, where clusters of QTLs for all trait categories appear close, established that the sd1 semi-dwarfing gene coincided with a plant height meta-QTL, that the drought avoidance meta-QTL was not likely to be associated with this gene, and that this meta-QTL was not pleiotropic with close meta-QTLs for leaf morphology and root traits. On chromosome 5, evidence suggests that a drought avoidance meta-QTL was pleiotropic with leaf morphology and plant biomass meta-QTLs, but not with meta-QTLs for root traits and plant height 10 cM lower down. A region of dense root QTL activity graphically visible on chromosome 9 was dissected into three meta-QTLs within a space of 35 cM. The confidence intervals for meta-QTLs obtained ranged from 5.1 to 14.5 cM with an average of 9.4 cM, which is approximately 180 genes in rice. Additional file 1 Alignment of markers on the Bala

    Forests cover almost one third of the Earth's land area and their distribution is changing as a result of human activities. The presence, and removal, of forests affects the climate in many ways, with the net climate impact of deforestation dependent upon the relative strength of these effects (Betts, 2000; Bala et al., 2007; Davin and de Noblet-Ducoudré, 2010). In addition to controlling the surface albedo and exchanging carbon dioxide (CO2) and moisture with the atmosphere, vegetation emits biogenic volatile organic compounds (BVOCs), which lead to the formation of biogenic secondary organic aerosol (SOA) and alter the oxidative capacity of the atmosphere, affecting ozone (O3) and methane (CH4) concentrations. In this work, we combine a land-surface model with a chemical transport model, a global aerosol model, and a radiative transfer model to compare several radiative impacts of idealised deforestation scenarios in the present day. We find that the simulated reduction in biogenic SOA production, due to complete global deforestation, exerts a positive combined aerosol radiative forcing (RF) of between +308.0 and +362.7 mW m-2; comprised of a direct radiative effect of between +116.5 and +165.0 mW m-2, and a first aerosol indirect effect of between +191.5 and +197.7 mW m-2. We find that the reduction in O3 exerts a negative RF of -150.7 mW m-2 and the reduction in CH4 results in a negative RF of -76.2 mWm-2. When the impacts on biogenic SOA, O3 and CH4 are combined, global deforestation exerts an overall positive RF of between +81.1 and +135.9 mW m-2 through changes to short-lived climate forcers (SLCF). Taking these additional biogeochemical impacts into account increases the net positive RF of complete global deforestation, due to changes in CO2 and surface albedo, by 7-11%. Overall, our work suggests that deforestation has a stronger warming impact on climate than previously thought. References: Bala, G. et al., 2007. Combined climate and carbon-cycle effects

    Rice (Oryza sativa) varieties that are arsenate-tolerant (Bala) and -sensitive (Azucena) were used to conduct a transcriptome analysis of the response of rice seedlings to sodium arsenate (AsV) in hydroponic solution. RNA extracted from the roots of three replicate experiments of plants grown for 1 week in phosphate-free nutrient with or without 13.3 muM AsV was used to challenge the Affymetrix (52K) GeneChip Rice Genome array. A total of 576 probe sets were significantly up-regulated at least 2-fold in both varieties, whereas 622 were down-regulated. Ontological classification is presented. As expected, a large number of transcription factors, stress proteins, and transporters demonstrated differential expression. Striking is the lack of response of classic oxidative stress-responsive genes or phytochelatin synthases/synthatases. However, the large number of responses from genes involved in glutathione synthesis, metabolism, and transport suggests that glutathione conjugation and arsenate methylation may be important biochemical responses to arsenate challenge. In this report, no attempt is made to dissect differences in the response of the tolerant and sensitive variety, but analysis in a companion article will link gene expression to the known tolerance loci available in the BalaxAzucena mapping population.

    Samples in the quaternary system (La/sub 1-//sub y/Pr/sub y/)(Ba/sub 2-//sub x/La/sub x/)Cu 3 O/sub 7+//sub δ/ have been prepared and characterized using x-ray and neutron diffraction, thermogravimetric analysis, and transport and magnetic measurements. Pr substitutes on the oxygen-depleted La layers for y>0.0, while La substitutes on the Ba sites for x>0.0. The effect of doping on each site is inferred to be primarily local, affecting immediately adjacent Cu-O layers. The similar suppression of superconductivity that accompanies doping on each of the two distinct sites apparently correlates with the degree of oxidation of the Cu-O sheets (and not the chains), indicating that the sheets support the high temperature superconductivity. Comparison of orthorhombic and tetragonal samples with similar Ba:La ratios (and y = 0) demonstrates that the orthorhombic phase yields the largest Meissner signals and highest transition temperatures in the La(Ba/sub 2-//sub x/La/sub x/)Cu 3 O/sub 7+//sub δ/ system

  16. Search performance is better predicted by tileability than presence of a unique basic feature

    Chang, Honghua; Rosenholtz, Ruth

    2016-01-01

    Traditional models of visual search such as feature integration theory (FIT; Treisman & Gelade, 1980), have suggested that a key factor determining task difficulty consists of whether or not the search target contains a “basic feature” not found in the other display items (distractors). Here we discriminate between such traditional models and our recent texture tiling model (TTM) of search (Rosenholtz, Huang, Raj, Balas, & Ilie, 2012b), by designing new experiments that directly pit these models against each other. Doing so is nontrivial, for two reasons. First, the visual representation in TTM is fully specified, and makes clear testable predictions, but its complexity makes getting intuitions difficult. Here we elucidate a rule of thumb for TTM, which enables us to easily design new and interesting search experiments. FIT, on the other hand, is somewhat ill-defined and hard to pin down. To get around this, rather than designing totally new search experiments, we start with five classic experiments that FIT already claims to explain: T among Ls, 2 among 5s, Q among Os, O among Qs, and an orientation/luminance-contrast conjunction search. We find that fairly subtle changes in these search tasks lead to significant changes in performance, in a direction predicted by TTM, providing definitive evidence in favor of the texture tiling model as opposed to traditional views of search.

    Agni (digestive fire), Prakruti (constitution), Dhatusarata (tissue excellence), Dosha (bio–energies) are the specialties of Ayurveda on which diagnosis, treatment and research are based. The description of Dhatusarata (tissue excellence) has been given under Dashavidha Pariksha (tenfold examination) in Charak Samhita, Viman Sthana, 8th chapter. Some qualities, which are mentioned in Dhatusarata are difficult to assess, e.g. Sukha, Aishwarya, Upabhoga, Bala, etc., There is a need to develop some quantitative parameters to measure these qualities according to tissue excellence i.e. Dhatusarata. By assessing Dhatu Sarata, one can judge the true strength of a particular Dhatu but only the ability or strength is not enough to get success; the liking or interest is also essential to achieve success. The purpose of this study is to elaborate the concept of Dhatusarata and reveal different aspects of Sukha according to the quality of that particular Dhatu in context of vocational guidance. It will help to establish interrelationship between Dhatusarata and vocational guidance. It will be assessed whether this Sukha quality is merely happiness or having different shades according to the excellence of Dhatus and whether this study is useful in guiding the person to choose appropriate profession, which will be according to his liking and ability. It has been concluded that shades of Sukha quality varies with particular Dhatusaras, which may be helpful in guiding a suitable profession to an individual which will be according to his ability and liking i.e. Sukha for intimate success.

    Today Down's syndrome is recognizable on the basis of its clinical c haracteristics in infants. According to present knowledge, Down's syndr ome can be classified cytogenetically into 4 groups: regular trisomy, translocational trisomy, mosaic forms and double trisomies. Knowledge of the karyotype is used in genetic counselling for further prevention of Down's syndrome in unborn fetuses. Prenatal chromosome analyses, a form of intrauterine diagnosis, has been used in Hungary since 1968. The average incidence of Down's syndrome has been estimated at 1.5:1000 among newborns. The mother's age and genetic deviations are determinant s in whether or not the syndrome will occur. The risk of Down's syndrome increases from 1 per 1000 in mothers under 30 to 10-20 per 1000 in mothers over 45. Since risk increases with the mother's age amniocen tesis should be routinely performed in pregnancies of older mothers. In the case of trisomy verified by intrauterine diagnosis, termination of pregnancy is advised. If population cytogenetic investigations are practiced, the carriers of the balanced translocation will be revealed and within a few years there will be only 3 indications for amniocentesis: 1) in cases of mother's advanced age, 2) in cases of bala nced translocation carrier and 3) in cases of a previously affected chil d disregarding the parental karyotypes. The expected risk of Down's syn drome predictable from available data if higher than 1-5% justifies intr auterine chromosome analysis.

    Regards and Tribute: Late Dr Narender Hasija was a mentor and visionary in the light of knowledge and experience. We pay our regards with deepest gratitude to the departed soul to rest in peace. Bolton's ratios help in estimating overbite, overjet relationships, the effects of contemplated extractions on posterior occlusion, incisor relationships and identification of occlusal misfit produced by tooth size discrepancies. To determine any difference in tooth size discrepancy in anterior as well as overall ratio in different malocclusions and comparison with Bolton's study. After measuring the teeth on all 100 patients, Bolton's analysis was performed. Results were compared with Bolton's means and standard deviations. The results were also subjected to statistical analysis. Results show that the mean and standard deviations of ideal occlusion cases are comparable with those Bolton but, when the mean and standard deviation of malocclusion groups are compared with those of Bolton, the values of standard deviation are higher, though the mean is comparable.

    The root-knot nematode Meloidogyne graminicola is one of the most serious nematode pests worldwide and represents a major constraint on rice production. While variation in the susceptibility of Asian rice (Oryza sativa) exists, so far no strong and reliable resistance has been reported. Quantitative trait loci for partial resistance have been reported but no underlying genes have been tagged or cloned. Here, 332 accessions of the Rice Diversity Panel 1 were assessed for gall formation, revealing large variation across all subpopulations of rice and higher susceptibility in temperate japonica accessions. Accessions Khao Pahk Maw and LD 24 appeared to be resistant, which was confirmed in large pot experiments where no galls were observed. Detailed observations on these two accessions revealed no nematodes inside the roots 2 days after inoculation and very few females after 17 days (5 in Khao Pahk Maw and 100 in the susceptible controls). These two cultivars appear ideal donors for breeding root-knot nematode resistance. A genome-wide association study revealed 11 quantitative trait loci, two of which are close to epistatic loci detected in the Bala x Azucena population. The discussion highlights a small number of candidate genes worth exploring further, in particular many genes with lectin domains and genes on chromosome 11 with homology to the Hordeum Mla locus. © The Author 2015.

    Full Text Available Ayurveda, manoeuvres mankind to head a healthy life in order to pursue four-fold bliss. With a view to combat physical and mental annoyances, classics have explicated two-fold therapeutic modalities; langhana/depletion and brihmana/nourishing. Upavasa /fasting is one among ten depletion therapies explained. It is envisioned at all three levels of Ayurvedic therapies- rational/objectively planned, psychological, and spiritual. Fasting is reckoned to be refraining from all forms of food intake for a given period, under supervision of a qualified physician. Acharya Charaka advocates fasting in diseases of milder intensity, in those due to aama (metabolic toxin, after purificatory procedures. Fasting person should avoid beautifying oneself, day sleep, sexual acts, and feasting prior and ulterior to fasting. Fasting is contraindicated in very young, elderly, emaciated, pregnant lady, and shortly after strenuous exercise. The principle avers that fasting kindles metabolic/digestive fire which, in absence of food, brings about paachana of vitiated doshas, thereby riposting health. Sound fasting ensues proper elimination of excretory wastes, clear belch, sweat, and taste for food. Benefits of fasting include lucidity of sense organs, lightness of body and mind, control of diseases, and enthusiasm. Yoga Shastra describes fasting with respect to three levels of food: physical, impressions, and associations and a means to unite three bodies: astral, physical, and causal. Ayurveda thus advocates fasting depending upon the dosha, agni, vaya, kala, and bala of the individual, as a preventive as well as therapeutic modality.

    The environmental radioactivity caused by the reactor accident at Chernobyl' was investigated from May 7 to May 31 of 1986 in Toyama. Measurement of radioactivities in airborne particles, rain water, drinking water, milk, and mugwort are carried out by gamma-ray spectrometry (pure Ge detector; ORTEC GMX-23195). Ten different nuclides ( 103 Ru, 106 Ru, 131 I, 132 Te-I, 134 Cs, 136 Cs, 137 Cs, 140 Ba-La) are identified from samples of airborne particles. In the air samples, a maximum radioactivity concentration of each nuclide is observed on 13th May 1986. The time of the reactor shut-down and the flux of thermal neutron at the reactor were calculated from 131 I/ 132 I and 137 Cs/ 134 Cs ratio. The exposure dose in Toyama by this accident is given as follows: internal exposure; [thyroid] adult-59 μSv, child-140 μSv, baby-130 μSv, [total body] adult-0.2 μSv, child, baby-0.4 μSv, external exposure; 7 μSv, effective dose equivalent; adult-9 μSv, child-12 Sv, baby-11 μSv.

    Full Text Available Ural Federal University (UrFU and VTT have performed joint research on development of industrial technologies for the extraction of REM and Scandium compounds from phosphogypsum and Uranium ISL leachate solutions. Leaching-absorption experiments at UrFU have been supported with multicomponent solution modelling by VTT. The simulations have been performed with VTT’s ChemSheet/Balas program and can be used for speciation calculations in the lixiviant solution. The experimental work combines solvent extraction with advanced ion exchange methodology in a pilot facility capable of treating 5 m3 solution per hour. Currently, the plant produces cerium carbonate, lanthanum oxide, neodymium oxide and concentrate of heavy rare earth metals. A batch of 45 t solids has been processed with the gain of 100 kg’s of REM concentrate. A mini-pilot plant with productivity above 50 liters per hour has been applied to recover scandium oxide and REE concentrates from the uranium ISL solution. As the preliminary product contains radioactivity (mainly strontium, an additional decontamination and cleaning of both concentrates by extraction has rendered a necessity. Finally a purified 99% concentrate of scandium oxide as well as 99% rare earth concentrate are received.

    The radioactivity levels in the air of the radionuclides released by the Fukushima accident were measured at the Laboratoire Souterrain de Modane, in the South-East of France, during the period 25 March-18 April 2011. Air-filters from the ventilation system exposed for one or two days were measured using low-background gamma-ray spectrometry. In this paper we present the activity concentrations obtained for the radionuclides (131)I, (132)Te, (134)Cs, (137)Cs, (95)Nb, (95)Zr, (106)Ru, (140)Ba/La and (103)Ru. The activity concentration of (131)I was of the order of 100 μBq/m(3), more than 100 times higher than the activities of other fission products. The highest activities of (131)I were measured as a first peak on 30 March and a second peak on 3-4 April. The activity concentrations of (134)Cs and (137)Cs varied from 5 to 30 μBq/m(3). The highest activity concentration recorded for Cs corresponded to the same period as for (131)I, with a peak on 2-3 April. The results of the radioactivity concentration levels in grass and mushrooms exposed to the air in the Modane region were also measured. Activity concentrations of (131)I of about 100 mBq/m(2) were found in grass. Copyright © 2012 Elsevier Ltd. All rights reserved.

  7. Biallelic and Genome Wide Association Mapping of Germanium Tolerant Loci in Rice (Oryza sativa L..

    Full Text Available Rice plants accumulate high concentrations of silicon. Silicon has been shown to be involved in plant growth, high yield, and mitigating biotic and abiotic stresses. However, it has been demonstrated that inorganic arsenic is taken up by rice through silicon transporters under anaerobic conditions, thus the ability to efficiently take up silicon may be considered either a positive or a negative trait in rice. Germanium is an analogue of silicon that produces brown lesions in shoots and leaves, and germanium toxicity has been used to identify mutants in silicon and arsenic transport. In this study, two different genetic mapping methods were performed to determine the loci involved in germanium sensitivity in rice. Genetic mapping in the biparental cross of Bala × Azucena (an F6 population and a genome wide association (GWA study with 350 accessions from the Rice Diversity Panel 1 were conducted using 15 μM of germanic acid. This identified a number of germanium sensitive loci: some co-localised with previously identified quantitative trait loci (QTL for tissue silicon or arsenic concentration, none co-localised with Lsi1 or Lsi6, while one single nucleotide polymorphism (SNP was detected within 200 kb of Lsi2 (these are genes known to transport silicon, whose identity was discovered using germanium toxicity. However, examining candidate genes that are within the genomic region of the loci detected above reveals genes homologous to both Lsi1 and Lsi2, as well as a number of other candidate genes, which are discussed.

    Full Text Available Este trabajo considera algunas conexiones entre la Cábala y la masonería en Rusia como se refleja en los archivos del Departamento de Manuscritos de la Biblioteca Estatal Rusa (DMS RSL. El vínculo entre ellos se basa en la comprensión tanto de la Cabala yla masonería como la filosofía simbólica y “verdaderamente metafísica”. En el artículo se muestra cómo los masones rusos adoptaron doctrinas cabalísticas de Ein-Soph, Sephiroth, Adam Kadmon y los mezclan con la teoría del neoplatonismo de la emanación, elmisticismo cristiano apofática, la cosmovisión hermética, la alquimia y la sofilogíacristiana. Esta adaptación ecléctica se basa en la interpretación de estos símbolos masónicos como punto en un círculo, columnas Jaquín y Boaz, y la estrella flameante. El simbolismo masónico permitió la combinación de diferentes doctrinas esotéricas en una cosmovisión unificada para hacer símbolos masónicos más atractivos para la “medio educada” nobleza rusa.

    To evaluate repeatability of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters in the orbit. From December 2015 to March 2016, 22 patients were scanned twice using an IVIM sequence with 15b values (0-2,000 s/mm{sup 2}) at 3.0T. Two readers independently delineated regions of interest in an orbital mass and in different intra-orbital and extra-orbital structures. Short-term test-retest repeatability and inter-observer agreement were assessed using the intra-class correlation coefficient (ICC), the coefficient of variation (CV) and Bland-Altman limits of agreements (BA-LA). Test-retest repeatability of IVIM parameters in the orbital mass was satisfactory for ADC and D (mean CV 12% and 14%, ICC 95% and 93%), poor for f and D*(means CV 43% and 110%, ICC 90% and 65%). Inter-observer repeatability agreement was almost perfect in the orbital mass for all the IVIM parameters (ICC = 95%, 93%, 94% and 90% for ADC, D, f and D*, respectively). IVIM appeared to be a robust tool to measure D in orbital lesions with good repeatability, but this approach showed a poor repeatability of f and D*. (orig.)

    Root system architecture (RSA) impacts plant fitness and crop yield by facilitating efficient nutrient and water uptake from the soil. A better understanding of the effects of soil on RSA could improve crop productivity by matching roots to their soil environment. We used x-ray computed tomography to perform a detailed three-dimensional quantification of changes in rice (Oryza sativa) RSA in response to the physical properties of a granular substrate. We characterized the RSA of eight rice cultivars in five different growth substrates and determined that RSA is the result of interactions between genotype and growth environment. We identified cultivar-specific changes in RSA in response to changing growth substrate texture. The cultivar Azucena exhibited low RSA plasticity in all growth substrates, whereas cultivar Bala root depth was a function of soil hardness. Our imaging techniques provide a framework to study RSA in different growth environments, the results of which can be used to improve root traits with agronomic potential. PMID:27208237

    2018-05-01

    This paper reports performance simulation of a unipolar tunable band gap InAs-InAsSb type-II superlattice (T2SL) infrared photodetector. The generation-recombination and surface leakage currents limit the performance of T2SL photodiodes. Unipolar nBn device design incorporating a suitable barrier layer in the diode structure is taken to suppress the Auger recombination and tunneling currents. At low reverse bias, the generation-recombination current is negligible in the absence of a depletion region, but the dark current is dominated by the diffusion current at higher operation temperatures. The composition, band alignment, barrier width, doping level and thickness of the absorber region are optimized here to achieve low dark current and high quantum efficiency at elevated operating temperatures. Thin unipolar T2SL absorbers are placed in a resonant cavity to enhance photon-material interaction, thus allowing complete absorption in a thinner detector element. It leads to the reduction in the detector volume for lower dark current without affecting the quantum efficiency. It shows an improvement in the quantum efficiency and reduction in the dark current. Dark current density ˜ 10-5 A/cm2 is achievable with low absorber thickness of 2 μm and effective lifetime of 250 ns in the InAs/InAs0.6Sb0.4/B-AlAs1-x Sb x long wave length T2SL detector at 110 K.

    Rhone CC v CERN CC at Parc de Parilly, Lyon on Sunday 11th September 2011 CERN travelled to Lyon to play our old friends Rhone at their new ground in the pretty and busy Parilly Parc. With no traffic problems CERN were at the ground in good time and even had time for a pre game kick around before skipper Elvin won the toss and decided to bowl. Onions and Chaudhuri opened the bowling and were penalized by some strict wide calling from the Rhone umpires. Onions finally made the breakthrough with the help of a brilliant running catch from the athletic Price. Chaudhuri then picked up 2 more Rhone wickets in a fiery opening spell as CERN took control. Rhone then rallied and Shiva made 50 before S. Ahmed had him trapped LBW. Skipper Elvin then turned to McFayden and the evergreen I. Ahmed to try and wrestle control back and McFayden was unlucky not to have Bala caught behind when the only person who did not think he had edged it was the umpire! Price again took another stunning catch in the deep to give I. Ahmed ...

    Full Text Available Brecht’s ‘canonical’ literary work’s indigenization in Pakistan can offer a valuable transcultural adaptation study because it was performed through a radical theatre with a distinct dramaturgy and political philosophy in two different cultural contexts and historical frame of references. As the foremost representative of Brecht’s radical dramaturgy, philosophy and literary works in Pakistan since 1983, Ajoka theatre utilized these adaptations as socio-political spaces to challenge dominant discourses on the rise of dictatorship and capitalism in Pakistan. Prior studies explored the formal elements of these adaptations of The Resistible Rise of Arturo Ui(1942 : visual and aural and the intellectual content i.e. political dimension of this ‘social action theatre’ is still unexamined. This contextual reading attempts to fulfill this ‘gap’ by conducting a seminal contextual criticism on ‘literary representations’ of Pakistani pro-capitalist dictators in selected transcultural adaptations of Brecht’s work in light of new historicism and Hutcheon’s Theory of Adaptation. The article also explores how in the second phase Brecht’s social and political philosophy is reflected in Ajoka’s signature plays, Bala King (1997 and The Third Knock (1970.

Place and Duration of Study: Dist. Hattian Bala of Azad Jammu and Kashmir (AJK) from Oct 2015 to Dec 2015. Material and Methods: A total of 410 women between 12-45 years of age were included in the study and grouped according to educational qualification. Women who were health-care workers, already diagnosed with the disease or those who had never heard of the disease were not included in the study. A self-made, pre-validated questionnaire including demographic data and 24 items assessing knowledge, attitude, and practice (KAP) regarding osteoporosis was administered after obtaining verbal informed consent. The scores ranged from 0-15 in knowledge section, 0-4 in attitude section and 0-8 in practice section. The results in each section of KAP were cross tabulated with educational status of the respondents. Results: Books and teachers (34.60 percent) were the main source of information followed by television/ radio (22.40 percent). The mean score for knowledge section was 5.12 +- 1.11, for attitude section 1.65 +- 0.64, and for practice 3.79 +- 2.61. All the three dimensions had significantly better results in women with higher educational status (graduate or more). Conclusion: Women with higher education demonstrated better knowledge, positive attitude and healthier practice than those with lower education. (author)

    Gilgit-Baltistan province is the northern most province of Pakistan having its eastern, northern and western boarders with India, China and Afghanistan respectively. The geology of this province is unique as it has the spectacular tectonic entities of Asiatic plate (AP), Indian plate (IP) and the Kohistan-Ladakh arc (KLA). The Northern Suture Zone (NSZ) or Main Karakoram Thrust (MKT) separate the KLA from AP in the north while the Maim Mantle Thrust (MMT) separate the KLA from IP in the south. These different tectonic events have generated various types of igneous and metamorphic rocks in the form of gigantic mountain chains in the region. Considering the metallogenic provinces related to such types of tectonic environments world over, it can be suggested that the Gigit-Baltistan province may have the potential for the occurrence of economic mineral deposits. The present study is the follow-up of the previous studies for exploration of gold and base metals conducted by the Austrominerals and the Pakistan Mineral Development Corporation (PMDC) in the region. On the basis of PMDC extensive stream sediments geochemical survey of the province and delineated number of anomalous catchment areas for gold mineralization. In order to find the source bed-rock of gold, we have identified various alteration zones in these catchment areas by applying Remote sensing techniques by using both multispectral (LANDSAT, ASTER and Geoeye) and hyperspectral (Hyperion) data. Most of the alteration zones were found in steep high altitude inaccessible terrains. During this study, few of the accessible alteration zones in Golo Das, Bagrot valley, Shigri Bala, Machulu and Ranthak areas were selected for geological filed work and collection of proper samples from the alteration zones and host rocks for the identification of possible gold mineralization. In all these localities, the alteration zones are present along shear zones where the sulfide mineralization commonly occurs in the form of

Os objetivos deste trabalho foram: avaliar características físico-químicas de amidos modificados com peróxido de hidrogênio, utilizar os amidos obtidos para a elaboração de doce de leite e bala de goma americana e verificar a aceitação sensorial destes produtos. Para obtenção das amostras modificadas, os amidos foram suspensos em solução de Fe2SO4.7H2O 0,01% e, em seguida, adicionou-se peróxido de hidrogênio 1,25%, ajustou-se o pH para 3,0, deixou-se reagir a 45 °C/15 minutos, lavou-se e secou-se a amostra em estufa de ventilação forçada a 45 °C/24 horas. Os amidos modificados apresentaram maior expansão, conteúdo de carboxilas, poder redutor e susceptibilidade à sinérese. Em relação à viscosidade aparente, verificou-se que com a modificação química houve diminuição no pico de viscosidade, especialmente quando as amostras foram analisadas em pH 7,0. A análise sensorial do doce de leite revelou que houve preferência pelas amostras elaboradas com amido de mandioquinha-salsa modificado e com o amido de milho regular ácido-modificado.

    with the relative activities of Cs-134/Co-60 (Co-60 is introduced as a dopant) to yield the burnup and enrichment for each pebble. Furthermore, a direct consequence of the relative approach is the ability to apply a self-calibration scheme using the multiple gamma lines of Ba-La-140 to establish the relative efficiency curve of the HPGe detector. An assessment of the expected uncertainty components in this approach showed that a maximum uncertainty of less than 5% should be feasible. To confirm the above findings, gamma-ray scans were performed on irradiated PULSTAR reactor fuel assemblies at North Carolina Sate University. The measurements used a 40% efficient n-type coaxial HPGe detector connected to an ORTEC DSPEC plus digital Gamma-Ray Spectrometer, and a data acquisition computer. The obtained results showed consistency with the predictions of the simulations including the observation of the I-132, Cs-134, Np-239 uncontaminated gamma lines. In addition, the Ba-La-140 lines were clearly observed confirming the ability to perform relative calibration of the spectrometer.

    The Kata-Rash arc fragment is an allochthonous thrust-bound body situated near Penjween, 100 km northeast of Sulymannia city, Kurdistan Region, within the Iraqi portion of the Zagros suture zone. It forms part of the suprasubduction zone 'Upper Allochthon' terranes (designated as the Gimo-Qandil Group), which is dominated by calc-alkaline andesite and basaltic-andesite, rhyodacite to rhyolite, crosscut by granitic, granodioritic, and dioritic dykes. Previously, rocks of the Kata-Rash arc fragment were interpreted as a part of the Eocene Walash volcanic group. However, SHRIMP zircon U-Pb dates on them of 108.1 ± 2.9 Ma (Harbar volcanic rocks) and 107.7 ± 1.9 Ma (Aulan intrusion) indicate an Albian-Cenomanian age, which is interpreted as the time of igneous crystallisation. The Aulan intrusion zircons have initial εHf values of + 8.6 ± 0.2. On a Nb/Yb-Th/Yb diagram, all Kata-Rash samples fall within the compositional field of arc-related rocks, i.e. above the mid-ocean-ridge basalt (MORB)-ocean island basalt (OIB) mantle array.

    In Sweden, the Swedish Forest Agency recommend ash recycling after whole-tree harvest (WTH), i.e. the whole tree above the stump is harvested. If this recommendation is complied, ash recycling will become a quite extensive forestry practice. To gain more knowledge regarding effects of ash on tree growth, storage of carbon (C) and nitrogen (N) in the upper soil, and soil-water chemistry, two field experiments were established. The experimental design was a randomized block design. Both experiments were installed on quite fertile sites in southern Sweden. On fertile sites (C/N less than 30), ash addition is hypothesized to increase tree growth, reduce the storage of C and N in the upper soil, and increase the concentrations of nitrate in soil water. One experiment (291 Guvarp) was established on a recently harvested clear cut. The sample plots were soil scarified by disc trenching and planted with Norway spruce (Picea abies L. Karst.) seedlings. Seedling height was measured at planting, and, two months later, seedling survival and height growth in 2011 was recorded. The other experiment (290 Bala) was located to a Norway spruce stand that was thinned by WTH. The initial registration and sampling comprised stand data and sampling of the upper soil (FH-layer). In addition, suction cups were installed at 50 cm depth for sampling of soil water. The experiments were designed for long-term monitoring, comprising several decades. For most of the variables registered, data did not show any significant differences among means for the plots representing different treatments. Pre-treatment data for individual plots showed acceptable comparability among plots within the blocks, which is a good starting point for detecting future changes caused by the treatments

The concentrations and standart deviation (in ppm) are: Be:6,25 (3,6); Sc:29 (12); Ti:5714 (2102); V:111,5 (29); Cr:118 (78); Co:17 (11); Ni:44 (25); Cu:24 (22); Ga:30 (20); Sr:134 (70); Y:51 (21); Zr:241 (69); Nb:24 (9); Mo:4,4 (1,2); Sn:11,5 (6); Ba:601 (314); La:112 (27); Pb:54 (58). The statistic error in the determination of the average concentrations is less than 15% por Ti, V, Zr, Mo and La, between 15% and 25% for Be, Sc, Ni, Sr, Y, Nb, Sn and Ba. The error for Cr, Co and Ga is between 25% and 30%. Cu and Pb show error near 40%. The figures indicate slight variations in the original composition of the rocks, which seems to be typical of a graywacke geosinclin association. The results show a very large similarity with the world average for 'shales', in relation to Ba, Cr, Co, Nb, Ti, V, Zr. For La, Ga, Pb, Mo, Sn, Sc, Be and Y the results are quite greater, while for Cu, Ni and Sr are smaller. There is good positive correlation between Ba-La, Ba-Sr, Be-Mo, Be-Sn, Y-Nb, Ga-Sn, Ga-Ba and Ga-La. As the elements La, Ga, Mo, etc. show hight values in relation to the known concentration levels in pelitic rocks, and considering the correlation between them, we believe that a metasomatism process rock place in the region, with introduction of that elements, from intrusive granite rocks.

Abstrak: Penanganan tindak pidana terorisme yang dilakukan pemerintah dapat dibedakan atas dua bidang, di dalam Lembaga Pemasyarakatan dan di luar Lembaga pemasyarakatan. Pendekatan hukum yang berdasarkan UU Nomor 15 tahun 2003 tentang Pemberantasan Tindak Pidana Terorisme belum secara optimal mengurangi potensi kekerasan atas tindak terorisme karena cenderung mempertontonkan penggunaan senjata. Beberapa keberhasilan penanganan tindak pidana terorisme ditandai adanya kerjasama narapidana terorisme dengan pemerintah untuk memberi informasi jaringan terorisme sekaligus pengakuan terhadap Negara Kesatuan Republik Indonesia (NKRI berdasarkan Pancasila. Pengembangan bina damai yang diterapkan pada teroris dapat menggurangi perlawanan dan balas dendam karena mengedepankan proses dialog daripada aksi militer bersenjata. Bina damai merupakan transisi dari proses rekonsiliasi menuju tahap konsolidasi untuk terbangunnya perdamaian yang permanen.

    Actual operating data from the Peach Bottom (PB) and Fort St. Vrain (FSV) High-Temperature Gas-Cooled Reactors (HTGRs) have been compared with code predictions to assess the validity of the methods used to predict the behaviour of fission products in the primary coolant circuit. For both reactors the measured circuit activities were significantly below design values, and the observations generally verify the codes used for large HTGR design. The PB primary circuit after seven years of operation was exceptionally clean. A fuel element purge system virtually eliminated the release of fission gases into the primary coolant circuit. Extensive examinations at end-of-life revealed that only Cs and trace amounts of Sr had plated out in the circuit. Their plateout distributions were in excellent agreement with PAD code predictions. Most of the deposited activity was associated with carbonaceous surface films which resulted from occasional small inleakages of lubricating oil. Primary circuit activities in FSV during the first cycle were also very low. Noble gas activity was about 1% of the design limit; and the circulating iodines were at least one order of magnitude below the limit, although the measurement uncertainties are significant. The plateout per pass of the iodine isotopes increased with decreasing half-life (the value for I-131 is about 1% per pass) as predicted with the PADLOC code. Gamma scanning of two helium circulators indicated very low plateout activities. Iodine-131 was the principal fission product observed, along with small amounts of Cs-134, Cs-137, and Ba/La-140.

    In this work, analytic signal amplitude (ASA) inversion of total field magnetic anomalies has been achieved by differential evolution (DE) which is a population-based evolutionary metaheuristic algorithm. Using an elitist strategy, the applicability and effectiveness of the proposed inversion algorithm have been evaluated through the anomalies due to both hypothetical model bodies and real isolated geological structures. Some parameter tuning studies relying mainly on choosing the optimum control parameters of the algorithm have also been performed to enhance the performance of the proposed metaheuristic. Since ASAs of magnetic anomalies are independent of both ambient field direction and the direction of magnetization of the causative sources in a two-dimensional (2D) case, inversions of synthetic noise-free and noisy single model anomalies have produced satisfactory solutions showing the practical applicability of the algorithm. Moreover, hypothetical studies using multiple model bodies have clearly showed that the DE algorithm is able to cope with complicated anomalies and some interferences from neighbouring sources. The proposed algorithm has then been used to invert small- (120 m) and large-scale (40 km) magnetic profile anomalies of an iron deposit (Kesikköprü-Bala, Turkey) and a deep-seated magnetized structure (Sea of Marmara, Turkey), respectively to determine depths, geometries and exact origins of the source bodies. Inversion studies have yielded geologically reasonable solutions which are also in good accordance with the results of normalized full gradient and Euler deconvolution techniques. Thus, we propose the use of DE not only for the amplitude inversion of 2D analytical signals of magnetic profile anomalies having induced or remanent magnetization effects but also the low-dimensional data inversions in geophysics.

    Silicic pyroclastic flows and related deposits are abundant along the Central American volcanic front. These silicic magmas erupted through both the non-continental Chorotega block to the southeast and the Paleozoic continental Chortis block to the northwest. The along-arc variations of the silicic deposits with respect to diagnostic trace element ratios (Ba/La, U/Th, Ce/Pb), oxygen isotopes, Nd and Sr isotope ratios mimic the along-arc variation in the basaltic and andesitic lavas. This variation in the lavas has been interpreted to indicate relative contributions from the slab and asthenosphere to the basaltic magmas [Carr, M.J., Feigenson, M.D., Bennett, E.A., 1990. Incompatible element and isotopic evidence for tectonic control of source mixing and melt extraction along the Central American arc. Contributions to Mineralogy and Petrology, 105, 369-380.; Patino, L.C., Carr, M.J. and Feigenson, M.D., 2000. Local and regional variations in Central American arc lavas controlled by variations in subducted sediment input. Contributions to Mineralogy and Petrology, 138 (3), 265-283.]. With respect to along-arc trends in basaltic lavas the largest contribution of slab fluids is in Nicaragua and the smallest input from the slab is in central Costa Rica — similar trends are observed in the silicic pyroclastic deposits. Data from melting experiments of primitive basalts and basaltic andesites demonstrate that it is difficult to produce high K 2O/Na 2O silicic magmas by fractional crystallization or partial melting of low-K 2O/Na 2O sources. However fractional crystallization or partial melting of medium- to high-K basalts can produce these silicic magmas. We interpret that the high-silica magmas associated Central America volcanic front are partial melts of penecontemporaneous, mantle-derived, evolved magmas that have ponded and crystallized in the mid-crust — or are melts extracted from these nearly completely crystallized magmas.

    Development of an effective and non-toxic radiation countermeasure has been a global challenge, till date. On one hand single molecules have failed due to unacceptable toxicity and on the other hand herbal drugs, though non-toxic, are generally neglected because of issues such as incomplete understanding on mechanisms of actions, efficacy and quality control. In the conventional drug discovery process, a single active constituent is isolated, purified, and standardized, but herbal drugs have complex composition and multiple targeted actions. The assessment of efficacy and toxicity of herbal drugs is, therefore, not as straight forward as in case of single active compound. The completion of genome projects of human, mouse and many other simpler experimental models has opened multiple newer avenues for evaluating the metabolism, safety and efficacy of herbal drugs. The radioprotective properties of leaves of Hippophae rhamnoides L. (common name Seabuckthorn, family Eleagnaceae) were reported (Bala et al., 2009, J Herbs and Med Plants). Administration of SBL-1 (a coded herbal preparation from Seabuckthorn leaves), before whole body exposure to lethal dose of 60 Co-gamma-rays (10 Gy), rendered >90% survivors in mice population, while 100% mortality was observed in non-SBL-1 treated, 60 Co-gamma- irradiated (10 Gy) controls. Though, plant H. rhamnoides is popular for its medicinal and neutraceutical values and finds place is in many traditional medicinal systems world over, its prophylactic use as a radiation countermeasure is novel and needed thorough evaluation. To gain in depth understanding on metabolism and safety of SBL-1, the experimental animals were treated with radioprotective concentration of SBL-1. The genome evaluation was performed at different time intervals after the treatment. This talk highlights some of the prominent molecular pathways and genes affected by SBL-1 treatment in experimental animals. Our study suggested that application of genomics

  4. Detection of cometary amines in samples returned by Stardust

    The abundances of amino acids and amines, as well as their enantiomeric compositions, were measured in samples of Stardust comet-exposed aerogel and foil using liquid chromatography with UV fluorescence detection and time of flight mass spectrometry (LC-FD/ToF-MS). A suite of amino acids and amines including glycine, L-alanine, β-alanine (BALA), γ-amino-n-butyric acid (GABA), ɛ-amino-n-caproic acid (EACA), ethanolamine (MEA), methylamine (MA), and ethylamine (EA) were identified in acid-hydrolyzed, hot-water extracts of these Stardust materials above background levels. With the exception of MA and EA, all other primary amines detected in cometexposed aerogel fragments C2054,4 and C2086,1 were also present in the flight aerogel witness tile that was not exposed to the comet, indicating that most amines are terrestrial in origin. The enhanced relative abundances of MA and EA in comet-exposed aerogel compared to controls, coupled with MA to EA ratios (C2054,4: 1.0 ± 0.2; C2086,1: 1.8 ± 0.2) that are distinct from preflight aerogels (E243-13C and E243-13F: 7 ± 3), suggest that these volatile amines were captured from comet Wild 2. MA and EA were present predominantly in an acid-hydrolyzable bound form in the aerogel, rather than as free primary amines, which is consistent with laboratory analyses of cometary ice analog materials. It is possible that Wild 2 MA and EA were formed on energetically processed icy grains containing ammonia and approximately equal abundances of methane and ethane. The presence of cometary amines in Stardust material supports the hypothesis that comets were an important source of prebiotic organic carbon and nitrogen on the early Earth.

    The existence in some volcanic products of strong excess of {sup 238}U with respect to {sup 230}Th is one of the characteristics of volcanic arc magmas. These excesses are generally attributed to fluid additions inside mantellic sources before magma segregation, differentiation and eruption. These fluids should be linked to the dehydration of the subducted rocks. These hypotheses are essentially based on correlations between {sup 10}Be, {sup 87}Sr anomalies, Ba/La ratios and on the distribution of volcanic centers with respect to the subduction zone. Recent studies suggest an evolution of the composition of volcanic sources in Central America from a depleted mantle type (MORB) in the North (Nicaragua) to a less transformed enriched type (OIB) in the South (Costa Rica). The Arenal volcano belongs to a transition zone between these two types. The preliminary study of trace elements and {sup 238}U-{sup 230}Th disequilibria in recent volcanic products (1968-1993) indicates a more complex situation. At least two different mantle sources were successively involved characterized by different Th/La and La/Yb ratios and very different to the OIB type. Also most lavas are in equilibrium with {sup 238}U/{sup 232}Th ratios of about 1.2 to 1.3. However, in eruptive cycle, some lavas are characterized by a strong {sup 238}U excess with respect to {sup 230}Th with cannot be linked to the sources, even when modified by fluids in depth. These results are interpreted in terms of heterogeneities of mantle sources and low depths late interactions with hydrothermal fluids during eruptions. Abstract only. (J.S.). 2 refs.

  8. Magmas with slab fluid and decompression melting signatures coexisting in the Gulf of Fonseca: Evidence from Isla El Tigre volcano (Honduras, Central America)

    Isla El Tigre volcano is located in the Gulf of Fonseca (Honduras) along the Central America volcanic front, where a significant change in the strike of the volcanic chain is observed. The studied samples of this poorly investigated volcano are mainly subalkaline basic to intermediate lavas (basalts and basaltic andesites) and subordinate subalkaline/alkaline transitional basalts, both having the typical mineralogical and geochemical characteristics of arc volcanic rocks. On the basis of petrographic and geochemical features, two groups of rocks have been distinguished. Lavas from the main volcanic edifice are highly porphyritic and hy-qz normative, and have lower MgO contents ( 5 wt.%), are ol-hy normative and show lower HFSE depletions relative to LILE and LREE, with lower Ba/La, Ba/Nb and Zr/Nb ratios. This suggests that mantle-derived magmas were not produced by the same process throughout the activity of the volcano. The bulk rock geochemistry and 87Sr/86Sr (0.70373-0.70382), 143Nd/144Nd (0.51298-0.51301), 206Pb/204Pb (18.55-18.58), 207Pb/204Pb (15.54-15.56) and 208Pb/204Pb (38.23-38.26) isotopic data of Isla El Tigre compared with the other volcanoes of the Gulf of Fonseca and all available literature data for Central America suggests that this stratovolcano was mainly built by mantle-derived melts driven by slab-derived fluid-flux melting, while magmas erupted through its parasitic cones have a clear signature of decompression melting with minor slab contribution. The coexistence of these two different mantle melting generation processes is likely related to the complex geodynamic setting of the Gulf of Fonseca, where the volcanic front changes direction by ca. 30° and two fundamental tectonic structures of the Chortis continental block, mainly the N-S Honduras Depression and the NE-SW Guayape Fault Zone, cross each other.

    Full Text Available Andesitic and andesitic-basaltic lavas are widespread over most of the ground surface of the Gurgur area altered mostly by the hydrothermal solutions. The main rock forming minerals in these rocks are plagioclase, pyroxene and olivine affected by the hydrothermal solutions. The altered rocks do contain minerals including calcite, sericite and chlorite. Given the results obtained and the mineral chemistry studies, the clinopyroxenes formed in the area are, chemically, calkalkaline and of diopside-augite type formed in subvolcanic to near surface levels contemporaneous with magma ascending. Plagioclase minerals show zoning textures and lie within the two andesine and albite-oligoclase fields. These units, in terms of total rock chemistry, are classified as the calk-alkaline volcanic rocks formed in the continental arcs. On the other hand, on the trace elements chondrite-normalized diagrams and enriched mantle-normalized multi- element diagrams, the LREE enrichment relative to the HREE is observed. The LILE (i.e. Rb, K and Th and the LREE (e.g. La, Ce and Nd show an enrichment in comparison to the HFSE (Zr, Hf, Nb, Yb, Y and Sm. Given the Nd/Th (1.42-1.15, Zr/Nb (12.27-21.22, Ba/La (18.64-29.77 as well as LILE enrichment associated with depletion in Nb, Ta and Ti, an environment related to the subduction zones can be proposed for the area under study. Moreover, the similarity between the REE distribution pattern and the incompatible elements point to the genetic relationship between these rocks. Finally, on the base of the obtained data, it can be concluded that the volcanic rocks in the Gurgur Mountain were likely formed during the extended magmatism of the Urumieh-Dokhtar in the Cenozoic.

    The Izu Bonin subduction zone has a history of abundant rhyolite production that is relevant to the development of intermediate to silicic middle crust. This study presents major and trace elemental compositions (via electron microprobe and LA-ICP-MS) of unaltered volcanic glass and phenocrysts from select medium- to high-K tephra intervals from IODP Site 1437 (Expedition 350, Izu Bonin Rear Arc). These data provide a time-resolved record of regional explosive magmatism ( 4.4Ma to present). Tephra from Site 1437 is basaltic to rhyolitic glass with accompanying phenocrysts, including hornblende. Glass compositions form a medium-K magmatic series with LREE enrichment (LaN/YbN = 2.5-6) whose trace element ratios and isotopic compositions are distinct from magmas with similar SiO2 contents in the main Izu Bonin volcanic front. Other workers have shown progressive enrichment in K and other trace element ratios moving from volcanic front westwards through the extensional region to the western seamounts in the rear arc. The <4.4 Ma rear-arc rhyolites from Site 1437 show pronounced negative Eu anomalies, high LaN/SmN (2-3.5), Ba/La <25 and Th of 1.5-4 ppm. These rhyolites show the highest variability for a given SiO2 content among all rear-arc magmas (rhyolites have 1.5-3.5 wt% K2O, Zr/Y of 1-8, LaN of 5-9 ppm) consistent with variability in literature reports of other rhyolite samples dredged from surrounding seamounts. Rhyolites have been dredged from several nearby seamounts with other high-K rhyolites dredged as close as nearby Meireki Seamount ( 3.8 Ma) and further afield in the Genroku seamount chain ( 1.88 Ma), which we compare to Site 1437 rhyolites. An extremely low-K rhyolite sill (13.6 Ma) was drilled lower in the section at Site U1437, suggesting that the mechanism for producing rhyolites in the Western Seamounts region changed over time. Rhyolites are either produced by differentiation of mafic magmas, by melting of pre-existing arc crust (as hypothesized in

    Objective: To establish the role of therapeutic bronchoalveolar lavage in addition to conventional treatment among two groups, with allergic bronchopulmonary aspergillosis, in terms of regression in serum IgE levels and clinical recurrence at 3 and 6 months of follow-up. Study Design: Aquasi-experimental study. Place and Duration of Study: Department of Pulmonology, Fauji Foundation Hospital, Rawalpindi, from July 2010 to December 2013. Methodology: The study was carried out on 132 patients who fulfilled the Greenberger and Patterson criteria and underwent a chest X-ray, an HRCT chest and classified radiologically as with Central Bronchiectasis (CB), High Attenuation Mucus (HAM) or Other Radiological Features (ORF). Baseline serum IgE levels were noted. All patients were given treatment including prednisolone and antifungal agent itraconazole for 4 months. Patients with ORF on HRCT chest and just received the medical treatment were labeled as conventional group. Those patients who had CB or HAM radiological features also underwent bronchoscopy with therapeutic Bronchoalveolar Lavage (BAL), labeled as BAL group. Clinical recurrence and serum IgE levels were noted at 3 and 6 months. Values were compared using chi-square and Mann-Whitney tests respectively. Results: Around 78 (59.1 percentage) of patients underwent bronchoscopy with therapeutic bronchoalveolar lavage to remove the mucus plugs. The mean serum IgE levels at baseline were 3312.04 ± 2526.217 and 3486.15 ± 2528.324 IU/ml in the BAL and conventional groups respectively. There was a statistically significant reduction in the mean serum IgE levels at 3 (p < 0.00) and 6 months (p < 0.001) of follow-up in BALas compared to conventional group. There was no significant difference in the clinical recurrence rate in both the groups (p=0.078 at 3 and 0.343 at 6 months respectively). Conclusion: Therapeutic bronchoalveolar lavage may be a useful adjunct to treatment in patients with allergic bronchopulmonary

    Early Paleozoic dioritic and granitic plutons in the Eastern Tianshan Orogenic Belt (ETOB) have been studied in order to constraint the initiation of a magmatic arc formed in this region. Zircon U-Pb dating indicates that two dioritic plutons in the northern ETOB were generated in the Late Ordovician (452 ± 4 Ma) and the Early Silurian (442 ± 3 Ma), respectively. Diorites from the two plutons are characterized by enrichments in large ion lithophile elements (LILE) and highly incompatible elements, with depletions in high field strength elements (HSFE) displaying typical geochemical features of a subduction-related origin. They have positive εNd(t) values (+5.08-+6.58), relatively young Nd model ages (TDM = 0.71-1.08 Ga), with Ta/Yb (0.05-0.09) and Nb/Ta ratios (12.06-15.19) similar to those of depleted mantle, suggesting a juvenile mantle origin. Their high Ba/La (13.3-35.9), low Th/Yb (0.72-2.02), and relatively low Ce/Th (4.57-14.7) and Ba/Th (47.8-235) ratios indicate that these diorites were probably produced by partial melting of a depleted mantle wedge metasomatized by both subducted sediment-derived melts and slab-derived aqueous fluids. Zircon U-Pb dating of a granitic pluton in the northern ETOB yielded a Late Ordovician intrusion age of 447 ± 5 Ma. Granites from this pluton show calc-alkaline compositions with geochemical characteristics of I-type granites. They also show positive εNd(t) values (+6.49-+6.95) and young Nd model ages (TDM = 0.69-0.87 Ga), indicating that the granites were most likely derived from juvenile lower crust. Our new dating results on the dioritic and granitic plutons suggest that arc-type magmatism in the northern ETOB began prior to or at the Late Ordovician (452-442 Ma). In addition, north-dipping subduction of the Kangguertage oceanic lithosphere may account for the arc-type magmatism and the geodynamic process of the ETOB in the Early Paleozoic.

    Basalt-trachyte volcanoes in the Marie Byrd Land (MBL) Cenozoic province lie along the Amundsen Sea coast on the north flank of the West Antarctic rift. Basalts here are characterized by OIB-like geochemistry, restricted ranges of 87Sr/86Sr (0.702535-0.703284) and 143Nd/144Nd (0.512839-0.513008) and a wide range of 206Pb/204Pb (19.357-20.934). Basalts at three MBL volcanoes display two anomalies compared with the above and with all other basalts in West Antarctica. They include 143Nd/144Nd (0.512778-0.512789) values at Mt. Takahe and Mt. Siple that are 2σ lower than other West Antarctic basalts, and Ba/Nb, Ba/La, and Ba/Th values at Mt. Murphy and Mt. Takahe that are 3-8 times higher than normal OIB. Isotope and trace element data do not support crustal and lithospheric mantle contamination, or the presence of residual mantle amphibole or phlogopite as explanations of these anomalies. The apparent coincidence of these anomalies with the site of a pre-Cenozoic convergence zone along the Gondwanaland margin suggests a subduction influence. Major episodes of subduction and granitic plutonism took place in MBL during the Devonian, Permian, and Late Cretaceous. Relicts in the source region, of components from these subducted slabs, provide a credible explanation for the uncoupling of Ba from other large ion lithophile elements (LILE), for its erratic distribution, and for the anomalously low 143Nd/144Nd at Mt. Takahe. The last episode of subduction ended 85 Ma, and was followed by continental break-up, rifting and lithospheric attenuation that produced the West Antarctic rift as we know it today. Thus, the enigmatic geochemical signatures in these three volcanoes seem to have been preserved roughly 61-85 m.y. after subduction ended. New calculations of source melting depth and a new determination of lithospheric thickness suggest that the source of the anomalies resides in a fossil mélange diapir that rose from the Cretaceous subducting slab, became attached to the

  18. The geochemistry of marine sediments, island arc magma genesis, and crust-mantle recycling

    To assess the role of sediment subduction and recycling in island arc magma genesis and mantle evolution, we have determined Sr, Nd, and Pb isotope ratios and the concentrations of K, Rb, Cs, Ba, Sr, U, Th, Pb and rare earth elements in 36 modern marine sediments, including Mn nodules, biogenic oozes, and pelagic and hemipelagic clays from the Pacific, Antlantic and Indian Oceans. Sr and Nd isotope ratios and the Sr/Nd concentration ratios in sediments are such that mixing between subducted sediment on the one hand and depleted mantle or subducted oceanic crust on the other can produce mixing arrays which may pass either through or outside of the oceanic basalt Sr-Nd isotope 'mantle array'. Thus whether isotope compositions of island arc volcanics (IAV) plot inside our outside of the mantle array is not a good indication of whether or not their sources contain a subducted sediment component. The presence of subducted sediment in the sources of IAV should lead to Cs/Rb and Pb/Ce ratios which are higher than those in oceanic basalts, and Ba/Rb ratios which may be either higher or lower than oceanic basalts. Simple mixing calculations suggest that as little as a percent or so sediment in island arc magma sources can account for the observed Cs/Rb, Pb/Ce, and Ba/Rb ratios in IAV. However, it does not appear that high Ba/La ratios and negative Ce anomalies in IAV are inherited from sediment in IAV magma sources. It is more likely these features reflect fractionation of alkalis and alkaline earths from rare earths during slab dehydration and metasomatism. Pb isotope ratios in sediments from the Warton Basin south of the Sunda Arc are collinear in 208 Pb/ 204 Pb- 207 Pb/ 204 Pb- 206 Bp/ 204 Pb space with volcanics from West Sunda, but not with volcanics from the East Sunda. This collinearity is consistent with the hypothesis that sediments similar to these are being subducted to the magma genesis zone of the West Sunda Arc. (orig./WB)

    Full Text Available Factors such as environmental conditions and nutrients are significant for successful growth and reproduction of microorganisms. Manipulations of the factors are the most effective way to stimulate the growth of the microorganism, which can be used to optimize the yield of a product. In this study, Central Composite Design (CCD of Response Surface Methodology (RSM was used to optimize the production of red pigment by Monascus purpureus FTC 5356 using the petioles of oil palm fronds (OPF as a substrate in solid state fermentation (SSF. The data was analyzed using Design Expert Software. The optimum combination predicted via RSM was confirmed through experimental work. The interactions between three variables such as initial moisture content (%, initial pH value (pH, and peptone concentration (% were studied and modelled. The statistical analysis of the results showed that the optimal conditions for red pigment production 47 AU/g with the biomass of 425.1 mg/g was at 55% initial moisture content, 3% of peptone, and at pH 3.  The RSM results showed that the initial pH value had a significant effect on red pigment production (P-value <0.05. The validation of these results was also conducted by fermentation with predicted conditions and it was found that there was a discrepancy of 0.39% between the values of the experimental result and those of the predicted values.

    Volcanoes of the Central American Volcanic Arc (CAVA) have produced at least 72 highly explosive eruptions within the last 200 ka. The eruption columns of all these “Plinian” eruptions reached well into the stratosphere such that their released volatiles may have influenced atmospheric chemistry and climate. While previous research has focussed on the sulfur and chlorine emissions during such large eruptions, we here present measurements of the heavy halogen bromine by means of synchrotron radiation induced micro-XRF microanalysis (SR-XRF) with typical detection limits at 0.3 ppm (in Fe rich standard basalt ML3B glass). Spot analyses of pre-eruptive glass inclusions trapped in minerals formed in magma reservoirs were compared with those in matrix glasses of the tephras, which represent the post-eruptive, degassed concentrations. The concentration difference between inclusions and matrix glasses, multiplied by erupted magma mass determined by extensive field mapping, yields estimates of the degassed mass of bromine. Br is probably hundreds of times more effective in destroying ozone than Cl, and can accumulate in the stratosphere over significant time scales. Melt inclusions representing deposits of 22 large eruptions along the CAVA have Br contents between 0.5 and 13 ppm. Br concentrations in matrix glasses are nearly constant at 0.4 to 1.5 ppm. However, Br concentrations and Cl/Br ratios vary along the CAVA. The highest values of Br contents (>8 ppm) and lowest Cl/Br ratios (170 to 600) in melt inclusions occur across central Nicaragua and southern El Salvador, and correlate with bulk-rock compositions of high Ba/La > 85 as well as low La/Yb discharged 700 kilotons of Br. On average, each of the remaining 21 CAVA eruptions studied have discharged c.100 kilotons of bromine. During the past 200 ka, CAVA volcanoes have emitted a cumulative mass of 3.2 Mt of Br through highly explosive eruptions. There are six periods in the past (c. 2ka, 6ka, 25ka, 40ka, 60ka, 75

  2. Hierarchy and Interactions in Environmental Interfaces Regarded as Biophysical Complex Systems

    Science.gov (United States)

    Mihailovic, Dragutin T.; Balaz, Igor

    The field of environmental sciences is abundant with various interfaces and is the right place for the application of new fundamental approaches leading towards a better understanding of environmental phenomena. For example, following the definition of environmental interface by Mihailovic and Balaž [23], such interface can be placed between: human or animal bodies and surrounding air, aquatic species and water and air around them, and natural or artificially built surfaces (vegetation, ice, snow, barren soil, water, urban communities) and the atmosphere. Complex environmental interface systems are open and hierarchically organised, interactions between their constituent parts are nonlinear, and the interaction with the surrounding environment is noisy. These systems are therefore very sensitive to initial conditions, deterministic external perturbations and random fluctuations always present in nature. The study of noisy non-equilibrium processes is fundamental for modelling the dynamics of environmental interface systems and for understanding the mechanisms of spatio-temporal pattern formation in contemporary environmental sciences, particularly in environmental fluid mechanics. In modelling complex biophysical systems one of the main tasks is to successfully create an operative interface with the external environment. It should provide a robust and prompt translation of the vast diversity of external physical and/or chemical changes into a set of signals, which are "understandable" for an organism. Although the establishment of organisation in any system is of crucial importance for its functioning, it should not be forgotten that in biophysical systems we deal with real-life problems where a number of other conditions should be reached in order to put the system to work. One of them is the proper supply of the system by the energy. Therefore, we will investigate an aspect of dynamics of energy flow based on the energy balance equation. The energy as well as

They can potentially be used as fluorescent probes for various biomedical imaging applications, including cancer localization, detection of micrometastasis, image guided surgery, and targeted drug delivery. Their main limitation is toxicity, which requires a biologically compatible surface coating to shield the toxic core from the surrounding environment. However, this leads to an increase in QD size that may lead to problems of excretion and systemic sequestration. We describe a one pot synthesis, characterization, and in vitro cytotoxicity of a novel polyhedral oligomeric silsesquioxane (POSS-coated CdTe-cored QD using mercaptosuccinic acid (MSA and D-cysteine as stabilizing agents. Characterization was performed using transmission electron microscopy Fourier transform infrared spectroscopy, and photoluminescence studies. POSS-coated QDs demonstrated high colloidal stability and enhanced photostability on high degrees of ultraviolet (UV excitation compared to QDs coated with MSA and D-cysteine alone (P value < 0.05. In vitro toxicity studies showed that both POSS and MSA-QDs were significantly less toxic than ionized salts of Cd+2 and Te-2. Confocal microscopy confirmed high brightness of POSS-QDs in cells at both 1 and 24 hours, indicating that these QDs are rapidly taken up by cells and remain photostable in a biological environment. We therefore conclude that a POSS coating confers biological compatibility, photostability, and colloidal

    Full Text Available Not a few Jewish historians have strongly criticized the spiritual and intellectual leaders of Spanish Jewry in the years leading up to the expulsion of 1492, as expressed by the following statement in a 1995 academic book by Norman Roth: “An important characteristic of fi fteenthcentury Spanish Jewry was the almost complete lack of leadership”. This article will challenge some of the underlying assumptions of this claim, especially pertaining to the failure of these leaders to foresee and prevent the expulsion, and the charge of intellectual mediocrity in the areas of Jewish law, philosophy and Kabbalah (Jewish mysticism. Passing briefly over the best-known Jewish leader of the generation, Don Isaac Abravanel, about whom much has been written, the second part of the article will focus on Rabbi Isaac Aboab, based largely on material from his sermons, much of which remains in unpublished manuscripts.

    Algunos historiadores judíos han criticado duramente los líderes espirituales e intelectuales de los sefardíes en los años previos a la expulsión de 1492, como pone de manifiesto Norman Roth en una publicación de 1995: “Una característica importante de los sefardíes del siglo XV fue la falta casi total de liderazgo”. Con el fi n de cuestionar algunos de los presupuestos subyacentes, este artículo pone en tela de juicio algunas de las asunciones fundamentales de esta afirmación, especialmente en lo que respecta al supuesto fracaso de esos líderes en prever y prevenir la expulsión, y a la acusación de mediocridad intelectual en los ámbitos de la ley, la filosofía y la cábala judías. Después de un breve acercamiento al líder judío más conocido de esa generación, Don Isaac Abravanel, sobre quien ya se ha escrito mucho, la segunda parte del artículo se centra en el rabí Isaac Aboab, basándose sobre todo en sus sermones, muchos de los cuales proceden de manuscritos todavía sin publicar.

Emboscados, en principio, lo fueron aquellos individuos, malos españoles en el imaginario colectivo de la derecha reaccionaria, que pudieron luchar contra la República y no lo hicieron. En la práctica, sin embargo, dicho calificativo respondió a un sentimiento muy concreto que se extendió por buena parte de la España Nacional y que vino a identificar a aquellos malos patriotas con los falangistas de la retaguardia. Así, mientras aquellos oportunistas conspiraban a salvo de las balas para imponer su modelo de estado totalitario y excluyente, en los frentes de batalla y a decir de los reaccionarios luchaban muchos españoles con nobleza y elevación de espíritu. Las continuas concentraciones, los desfiles, las misas al aire libre, los rituales nocturnos de antorchas protagonizadas por la Falange, aquella acusación, sin duda legítima a tenor de todo esto, se apoyó, no obstante, en una percepción torcida de la realidad.Ambushed, in principle, they were it who they could fight against the Republic and they didn’t make it. In the practice, however, that epithet was used by the reactionary right to attack the falangists of the rearguard. According to the reactionaries, while those opportunists conspired safe of the bullets to impose their model of totalitarian state, in the battle fronts many Spaniards fought with nobility and spirit elevation. The continuous concentrations, the parades, the religious rituals outdoors, the night rituals of brands played by the Falange, that accusation leaned on, nevertheless, in a bent perception of the reality. With this article, therefore, and using unpublished documental sources, we want to analyze the contribution of a Falange that became a fundamental pillar for the overthrow of the Second Spanish Republic in very little time.

    Full Text Available A dieta dos atletas requer aporte energético adequado, sendo a principal fonte energética os carboidratos CHO que são encontrados livremente na corrente sanguínea ou armazenados nos músculos e no fígado. Com base na rotina de treinos e competições, ou mesmo na quantidade exacerbada de energia necessária, é comum a necessidade de suplementação de CHO, seja na forma de bebidas, géis, barras ou balas energéticas, antes, durante ou depois da atividade física. Devido à importância dos CHO foram reunidos estudos que testaram a suplementação com diferentes CHO antes do exercício para aumento da performance. Foram investigados artigos e teses cuja publicação ocorreu a partir de 2006 em bases científicas eletrônicas e banco de teses de faculdades renomadas na área. Os CHO podem ser divididos segundo a quantidade de moléculas que o compõem, as quais também são diferenciadas também por digestão, absorção, viscosidade, dulçor, índice glicêmico IG e oxidação durante a atividade. Comparando-se a taxa de oxidação, foram encontrados melhores resultados quando os CHO ingeridos são de alto teor de IG glicose e sacarose e baixo teor de IG frutose ao se realizar atividade de média a alta intensidade de longa duração. A ingestão de CHO antes do exercício mostrou-se eficiente nos nove estudos analisados, sendo que dois deles apresentaram relevância p < 0,005. Mesmo com a ingestão de CHO com diferentes IG, observou-se melhora, não sendo relatada hipoglicemia de rebote como teorizado na literatura. A suplementação de CHO com a composição e administração apropriadas mostrou-se eficiente para aumento do desempenho físico.

Incretins secreted in response to ingestion of meals enhance insulin release to the blood, and DPP-IV inactivates these incretins within a short period and stops their action. Inhibition of this enzyme escalates the action of incretins and induces more insulin to achieve better glucose control in diabetic patients. Thus, inhibition of this enzyme will lead to better control of blood sugar levels.Methods: In this study, computer-aided drug design was used to help establish a novel N-substituted aminobenzamide scaffold as a potential inhibitor of DPP-IV. CDOCKER software available from Discovery Studio 3.5 was used to evaluate a series of designed compounds and assess their mode of binding to the active site of the DPP-IV enzyme. The designed compounds were synthesized and tested against a DPP-IV enzyme kit provided by Enzo Life Sciences. The synthesized compounds were characterized using proton and carbon nuclear magnetic resonance, mass spectrometry, infrared spectroscopy, and determination of melting point.Results: Sixty

    Hydrothermal systems are known to harbour a large number of microorganisms, but the organic chemical composition of the solution that comprises their potential substrate is largely unknown. Concentrations and distributions of dissolved free amino acids (DFAA) and dissolved combined amino acids (DCAA) were determined in fluids from the moderate-temperature (42-89{sup o}C), shallow hydrothermal system on the volcanically active island of Vulcano, Italy. The seven samples represent three different geological settings on the island; shallow ({approx} 1 m) submarine vents, geothermal wells, and seeps in heated beach sediments, in addition to ambient local seawater from the bay, Baia di Levante. All hydrothermal sites, with one exception, had TDAA concentrations that were 3-114 times higher than local seawater in Baia di Levante. There were large similarities in amino acid concentration and composition among samples from the same geological setting. The highest amino acid concentrations were found at sites with acidic and reducing conditions, which also had the largest freshwater component. An unusually high fraction of the TDAA pool was represented by DFAA (33-87%), possibly due to in situ acid hydrolysis of DCAA to DFAA. Both DFAA and DCAA concentrations were correlated to DOC, indicating similar source and sink functions for these pools. The yield of TDAA (TDAA-carbon as fraction of organic carbon) ranged from 2% to 25%, which is high compared with non-hydrothermal settings, and indicates high biological lability. The mole fraction of {beta}-alanine plus {gamma}-aminobutyric acid (% BALA + GABA) was 2-2.7% of TDAA, also indicating high biological lability. Owing to the high over-all amino acid concentrations, the high fraction of DFAAs, and the high biological lability of the organic matter, organic matter in general and amino acids specifically could represent significant carbon and energy sources for archaea and bacteria in this hydrothermal system.

    The Kekem shoshonitic gabbro-norite association is part of the high-K calc-alkaline (HKCA) post-collisional magmatism, a major feature of the Pan-African Belt in Cameroon. LA-ICP-MS U-Pb zircon analyses provide an age of 576 ± 4 Ma for the Kekem complex. This age is interpreted as dating the emplacement of the massif during the waning stage of the Pan-African orogeny. The latter is related to dextral movements along the Central Cameroon Shear Zone (CCSZ). The REE patterns display enriched LREE (LaN/YbN = 14.2-23.5) while HREE present a nearly flat profile (DyN/YbN = 1.3-1.7), and the La/Sm and Sm/Yb ratios led to propose that the Kekem gabbro-norites have been derived from the partial melting of a garnet-spinel lherzolite mantle source. The negative Nb-Ta and Ti anomalies and the positive Pb anomalies indicate that this mantle source was modified by contribution of a subduction-related material. The low Ce/Pb (2.6-10.4) and Th/Yb ratios associated to high Ba/La ratios, indicate that source enrichment could be related to slab derived fluids. As a whole, the Kekem geochemical features suggest that primary gabbro-noritic magmas derived from a subduction-modified mantle source (metasomatised lithospheric mantle). Moderately high 86Sr/87Sr initial ratios (0.7068-0.7082), low ɛNd (-5 to -9) and old Nd TDM model ages (1.6-1.8 Ga) are interpreted to result from contamination of Neoproterozoic mantle by the Paleoproterozoic crust. The ca. 576 Ma movements along the CCSZ are related to a Neoproterozoic metacratonization of the northern margin of the Congo craton during the Pan-African orogeny. This metacratonization led to vertical planar lithospheric delamination along lithospheric transcurrent faults, asthenospheric uprise and partial melting of the Paleoproterozoic lithospheric mantle.

    Full Text Available No processamento industrial da manga, os subprodutos, caroço e casca são, normalmente, descartados sem o devido aproveitamento. O objetivo deste trabalho foi investigar as características físico-químicas e funcionais dos amidos nativo e acidificado do caroço (amêndoa de manga, da variedade Tommy Atkins, pesquisando uma nova fonte de amido e formas de melhorá-la e contribuir para a utilização de resíduos da indústria alimentícia. As amêndoas foram retiradas manualmente dos caroços de manga e procedeu-se a extração do amido. O amido nativo foi acidificado, sendo o agente promotor da modificação o ácido clorídrico. Verificou-se a composição química do amido nativo. Determinaram-se também as propriedades funcionais e de pasta do amido nativo e do acidificado. Para a composição centesimal, o amido nativo apresentou 71,56% de amido, 7,30% de lipídeos e 5,6% de proteínas. Os amidos nativo e acidificado demonstraram baixa resistência à elevação da temperatura, com intumescimento máximo a 75 oC, sendo seus valores 9,395 e 6,861 g/g, respectivamente. A solubilidade mostrou-se crescente, à medida que houve elevação da temperatura, sendo seu valor máximo 48,03% para o amido acidificado. O amido nativo expôs maior capacidade de absorção de água, óleo e claridade da pasta. O referido amido ainda apresentou maior pico de viscosidade, viscosidade mínima, quebra de viscosidade, viscosidade final, retrogradação e temperatura de pasta do que os do amido acidificado. O amido nativo pode ser indicado para compor sopas desidratadas e produtos cárneos, enquanto o acidificado pode ser usado em alimentos congelados e refrigerados e na indústria de balas.

    Full Text Available OBJETIVO: Descrever e discutir a introdução de alimentos industrializados na dieta de crianças frequentadoras de berçários em creches, considerando a recomendação do Ministério da Saúde para uma alimentação saudável. MÉTODOS: Estudo transversal com 270 crianças frequentadoras de berçários de 8 creches públicas e filantrópicas do município de São Paulo. Por meio de questionário estruturado e pré-codificado, foi avaliada a introdução de alimentos a partir de 11 perguntas. Para cada alimento analisado foi registrada a idade em meses de introdução e avaliada a concordância com o oitavo passo do Guia Alimentar. No estudo das associações, utilizou-se o teste Qui-quadrado, a partir das variáveis idade e escolaridade maternas, renda familiar e trabalho da mãe fora do lar. RESULTADOS: Os resultados mostram que para aproximadamente 2/3 das crianças foram oferecidos, antes dos 12 meses, alimentos com potencial obesogênico, como macarrão instantâneo, salgadinhos, bolacha recheada, suco artificial, refrigerante e bala/pirulito/chocolate. São os filhos de mães com baixa escolaridade, mais jovens e com menor renda, os mais susceptíveis ao erro alimentar de introdução precoce de alimentos industrializados. CONCLUSÃO: Diante desses resultados, medidas educativas e preventivas devem ser propostas para a formação de hábitos alimentares saudáveis desde a infância, além da criação de campanhas abrangentes e efetivas que estimulem o consumo de frutas e hortaliças, considerando-se os fatores culturais, comportamentais e afetivos envolvidos com a alimentação.OBJECTIVE: This study described and discussed the introduction of processed foods to the diets of children attending the nurseries of daycare centers, considering the recommendation of the Ministry of Health for a healthy diet.

    Full Text Available The Rajahmundry Trap Basalts (RTB are erupted through fault-controlled fissures in the Krishna-Godavari Basin (K-G Basin of Godavari Triple Junction, occurring as a unique outcrop sandwiched between Cretaceous and Tertiary sediments along the east coast of India. Detailed geochemical studies have revealed that RTB are mid-Ti (1.74–1.92 to high-Ti (2.04–2.81 basalts with a distinct quartz tholeiitic parentage. MgO (6.2–13.12 wt.%, Mg# (29–50 and Zr (109–202 ppm suggest that these basalts evolved by fractional crystallization during the ascent of the parent magma along deep-seated fractures. Moderate to high fractionation of HREE, as indicated by (Gd/YbN ratios (1.71–2.31 of RTB, suggest their generation through 3–5% melting of a Fe-rich mantle corresponding to the stability fields of spinel and garnet peridotite at depths of 60–100 km. Low K2O/P2O5 (0.26–1.26, high TiO2/P2O5 (6.74–16.79, La/Nb (0.89–1.45, Nb/Th > 8 (8.35–13, negative anomalies at Rb reflect minimum contamination by granitic continental crust. (Nb/LaPM ratios (0.66–1.1 of RTB are attributed to endogenic contamination resulted through recycling of subducted oceanic slab into the mantle. Pronounced Ba enrichment with relative depletion in Rb indicates assimilation of Infra- and Inter-trappean sediments of estuarine to shallow marine character. Geochemical compositions such as Al2O3/TiO2 (3.88–6.83, medium to high TiO2 (1.74–2.81 wt.%, positive Nb anomalies and LREE enrichment of these RTB attest to their mantle plume origin and indicate the generation of parent magma from a plume-related enriched mantle source with EM I signature. Ba/Th (46–247, Ba/La (3.96–28.51 and Th/Nb (0.08–0.13 ratios suggest that the source enrichment process was marked by recycling of subduction-processed oceanic crust and lithospheric components into the mantle. Zr/Hf (37–41 and Zr/Ba (0.51–3.24 indicate involvement of an asthenospheric mantle source. The

Trace-element distribution is controlled by pressure, temperature and mineral assemblages. At low temperatures in the sediment layer (Ba, Rb, Sr and Li are much more mobile than REE and HFSE, which results in high Ba/La, Ba/Nb, Sr/Nb etc. (fluid metasomatism). At higher temperatures in the sediment layer, the melt is markedly enriched in Ba, Rb, Sr, LREE and U relative to Ti, MREE and HREE. Negative Nb-Ta and Zr-Hf anomalies in melts are caused by the retention of rutile, zircon and humite-group minerals in the solid residue. Thermodiffusion may affect the ratios of some highly incompatible elements (e.g., Ta/La). Possible applications of the results to natural deep subduction are discussed in view of variations in mineral assemblages and trace element ratios.

    transiciones democráticas latinoamericanas  que afirmaban que la democracia boliviana estaba  en camino hacia la consolidación y sugieren que  las investigaciones recientes acerca de la calidad  de la democracia en América Latina señalan nuevas pautas para repensar la democracia en la región. Tomando tales evaluaciones como punto de  referencia este artículo describe la ‘guerra del gas’  y examina la forma de funcionar de la democracia  boliviana durante las últimas décadas. Se argumentará que la ‘democracia pactada’, que durante  este período aseguró la institucionalidad, y el  modelo económico adoptado en 1985, excluyeron  a importantes sectores de la población, tanto en  términos políticos cómo en lo que se refiere al  alivio de la pobreza y la equidad. Protestas crecientes fueron reprimidas con una violencia  igualmente creciente, lo que paulatinamente convirtió a Bolivia en una ‘democradura’ o una ‘democracia gasificada’ – que necesita de gas lacrimógeno y balas para sustentarse. De momento, el país se encuentra en un cruce de caminos; o se reinventa la democracia o se institucionaliza la  ‘democradura’.

Os outros três coelhos que receberam 1g/kg desenvolveram sintomas discretos a moderados e se recuperaram, e os três que receberam 0,5g/kg só mostraram sintomas discretos. O período entre a administração das sementes e a morte ou recuperação variou de 12h47min a 68h08min, e de 3 a 6 dias, respectivamente. Os primeiros sintomas após a administração das sementes, foram observados dentro de cerca 8 horas nos casos letais e nos animais que adoeceram moderadamente, e dentro de cerca 24 horas nos casos com sintomatogia discreta. A evolução da intoxicação variou de 4 a 56 horas nos casos letais e de 2 a 5 meio dias nos casos de recuperação. A sintomatologia consistiu principalmente de perturbações digestivas. Os animais apresentaram inapetência até anorexia. As fezes geralmente eram escassas, com forma e tamanho das síbalas alteradas, eram escuras, às vezes pastosas, com muco. Havia nítidas manifestações de cólica. Os achados de necropsia mais evidentes foram constatados no intestino delgado e ceco. O conteúdo destes segmentos do intestino era líquido.

    that best explained the variability of SOC vulnerability, with alkaline soils being the most vulnerable. This could be explained by the strongest adsorption of nitrogen organic compounds to minerals at lower pH [5]. We conclude that in temperate forests, the control that soil properties exert on SOC dynamics might outweigh the control of climate. Therefore, soil properties should be appropriately represented in Earth system models to obtain more realistic projections under different climate scenarios. 1.

I have minutely searched with my students all the data of that tornado, the direction of wind gusts, we have calculated the force of the impact by studying the photos taken on that occasion. I have also done some research on other tornadoes that have taken place In Movilita and Brezoaele the past years. I have studied the increase of the centrifugal force and that of Coriolis in the context of repetition of such dangerous atmospheric phenomena that showed their apparition as ten per year in Romania. Therefore the average Coriolis parameter is 10-4 s-1, for a typical atmospheric speed of 10 m/s (22 mph) the radius is 100 km (62 mi), with a period of about 17 hours. The lowering of the air pressure occurring on such occasions has been one of my concerns as well the the speed of the cloud column rotation. All these phenomena are the effect of the climate change occurring all over our Planet due to pollution. As you can see the devastation produced by such extreme climate lead to spontaneous floods and later desertification on the south-eastern part of our country. References : 1.

El único litotipo empleado en la construcción es una caliza dolomítica de elevada porosidad procedente de canteras próximas a la ciudad. Los principales mecanismos de alteración son los de incremento de volumen en capilares e intersticios, ligados a la presencia de sales, y los de disolución, dada la solubilidad de las sales de magnesio de constitución, que pueden producir la desdolomitización de la piedra. Esto conduce a unos indicadores de alteración con una morfología típica consistente en huecos en todas sus manifestaciones: picados, alveolizaciones y cavernas. La mayor degradación se da en las partes altas y bajas del edificio, allí donde los factores viento y humedad, respectivamente, son más intensos. La alteración antropogénica también toma, casi irónicamente, la forma de huecos, como los impactos de balas y obuses de la fachada Sur y las regolas practicadas para cables eléctricos en todo el edificio. Diversas restauraciones han introducido tensiones en los materiales que han conducido a decohesiones en diversos grados (desagregaciones, disgregaciones y arenizaciones en el interior del templo y en el claustro. El edificio se encuentra en un estado de alteración de cierta significación que esencialmente afecta a la estética del mismo. La velocidad del proceso degradativo observada en ciertas áreas del mismo, en particular en las restauradas, reclama actuaciones urgentes para su mantenimiento.

  8. Crustal contributions to arc magmatism in the Andes of Central Chile

    Fifteen andesite-dacite stratovolcanoes on the volcanic front of a single segment of the Andean arc show along-arc changes in isotopic and elemental ratios that demonstrate large crustal contributions to magma genesis. All 15 centers lie 90 km above the Benioff zone and 280??20 km from the trench axis. Rate and geometry of subduction and composition and age of subducted sediments and seafloor are nearly constant along the segment. Nonetheless, from S to N along the volcanic front (at 57.5% SiO2) K2O rises from 1.1 to 2.4 wt %, Ba from 300 to 600 ppm, and Ce from 25 to 50 ppm, whereas FeO*/MgO declines from >2.5 to 1.4. Ce/Yb and Hf/Lu triple northward, in part reflecting suppression of HREE enrichment by deep-crustal garnet. Rb, Cs, Th, and U contents all rise markedly from S to N, but Rb/Cs values double northward - opposite to prediction were the regional alkali enrichment controlled by sediment subduction. K/Rb drops steeply and scatters greatly within many (biotite-free) andesitic suites. Wide diversity in Zr/Hf, Zr/Rb, Ba/Ta, and Ba/La within and among neighboring suites (which lack zircon and alkali feldspar) largely reflects local variability of intracrustal (not slab or mantle) contributions. Pb-isotope data define a limited range that straddles the Stacey-Kramers line, is bracketed by values of local basement rocks, in part plots above the field of Nazca plate sediment, and shows no indication of a steep (mantle+sedimentary) Pb mixing trend. 87Sr/86Sr values rise northward from 0.7036 to 0.7057, and 143Nd/144Nd values drop from 0.5129 to 0.5125. A northward climb in basal elevation of volcanic-front edifices from 1350 m to 4500 m elevation coincides with a Bougueranomaly gradient from -95 to -295 mgal, interpreted to indicate thickening of the crust from 30-35 km to 50-60 km. Complementary to the thickening crust, the mantle wedge beneath the front thins northward from about 60 km to 30-40 km (as slab depth is constant). The thick northern crust contains

    Agriculture represents 59 % of the anthropogenic nitrous oxide (N2O) emissions, according to the IPCC (Ciais et al. 2013). N2O emissions are typically irregular and vary widely in time and space, which makes it difficult to get a good representation of the emissions (Henault et al. 2012), particularly if measurements have low frequency and/or cover only a short time period. Manual measurements are, for practical reasons, often short-term and low-frequent, or restricted to periods where emissions are expected to be high, e.g. after fertilizing. However, the nature of N2O emissions, being largely unpredictable, calls for continuous or near-continuous measurements over long time periods. So far, rather few long-term, high resolution measurements of N2O emissions from arable fields are reported; among them are Flessa et al. (2002) and Senapati et al. (2016). In this study, we have a two-year data set (2015-2017) with hourly measurements from ten automatic chambers, covering unfertilized controls as well as different nitrogen fertilizer treatments. Grain was produced on the field, and effects of tillage, harvest and other cropping measures were covered. What we can see from the experiment is that (a) the unfertilized control plots seem to follow the same emission pattern as the fertilized plots, at a level similar to the standard mineral fertilized plots (120 kg N ha-1 yr-1) and (b) freeze/thaw emissions are comparable in size to emissions after fertilizing. These two findings imply that the importance of fertilizing to the overall N2O emissions from arable soils may be smaller than previously expected. References: Ciais, P., C. Sabine, G. Bala, L.

    üalist tavır ya da bir hesaplaşmayla bu işe girişmişlerdir. Edebî sahada ise, hesaplaşmanın Divan şiirinden başladığını ve bu şiiri eleştirerek yeni bir edebî anlayışın ortaya konulduğunu söylemek mümkündür. Divan şiirinin sosyal meseleleri anlatmaktan uzak durduğu, dilinin mübalağalı ve anlatımının da soyut olduğu ileri sürülerek, yeni yaşam tarzına bu şiirin cevap veremeyeceği çeşitli türlerin yardımıyla gösterilmeye çalışılmıştır. Tanzimat’la birlikte Batı’dan yapılan çevirilerle toplum hayatında varlığını gösteren ve yeni yaşam tarzının tercümanı şeklinde düşülen romanda da söz konusu eleştiriler somutlaştırılmış; yeninin içinde Divan şiirinin nasıl algılandığı ortaya konulmuştur. Başta Namık Kemal olmak üzere, diğer Tanzimat sanatkârları da romanlarında Divan edebiyatı türlerinden mesnevi, kaside ve gazelle ortaklık kurmakla birlikte, bu türlerde olmayan yeni anlatım tekniklerini de uygulamışlardır. Bu şekilde Divan şiiri, hem bir geleneğin parçası, hem de geleneğe eleştirel bir şekilde bakan zihinlerin ürünleri olarak yeninin içinde yer almıştır.Bu çalışmada, sade bir dille toplum gerçeklerini anlatmaktan yana olan Tanzimat sanatkârlarının Divan şiiriyle ilgili görüşlerine yer verildikten sonra, romanlarda bu görüşlerin ne şekilde yansıdığına cevap aranmıştır.

    relatively modest band masses for both electrons and holes suggesting applications. Optical properties show a infrared-red absorption when doped. This could potentially be useful for combining wavelength filtering and transparent conducting functions. Furthermore, our defect calculations show that Ba 2TeO is intrinsically p-type conducting under Ba-poor condition. However, the spontaneous formation of the donor defects may constrain the p-type transport properties and would need to be addressed to enable applications. Chapter 4 mainly devotes to the thermoelectric properties of the famous phase change material, Ge2Sb2Te5 (GST). GST has been used in data storage for more than a decade because of their fast phase switching between metastable crystalline (cubic) and amorphous phases. It also exhibits interesting thermoelectric properties, and we did a systematic study on the two crystalline phases (hexagonal and cubic) and the amorphous phase. We found a high Seebeck coefficient with a broad doping concentrations for both n-type and p-type, at and below room temperatures (300 K) for both the cubic and amorphous phases. This finding will be of crucial interests in further understand the thermoelectric properties experimentally and find device applications in the ultimate goal. Several magnetic materials that involve lanthanide elements are reported in Chapter 5. First of all, the electronic and magnetic properties of the BaLn2O4 (Ln = La-Lu, Y) family compound are studied. The series has been synthesized for the first time in single crystalline form, using a molten metal flux. They crystallize in the CaV 2O4 structure type with primitive orthorhombic symmetry (space group Pnma, #62). Our calculations show an insulating character with band gaps ranging from 3 eV to 4.5 eV for the three representative compounds, BaLa2O4, BaGd2O4 and BaLu 2O4. Moreover, the superexchange magnetism is also studied. Secondly, a strong correlated system with cerium is investigated. As expected, we

    Full Text Available Heart is one of the most common subject which place at Turkish Classical Literature of poetry’s Divan. The concept not only of Classical Literature, but also Folk Literature and oral culture among the topics deal with a lot of culture. İf there are love and lover in the beyit, heart of the lover absolutely take place in the world of the word at the same time. The poet who lived in the first half of the seventeeth century and found fame as a teacher of ode Nef‛î has included the concepts and comparisons in his Dîvân. The word, there are more than in the ghazals. The poet who wrote poetry in general, for the Sultan and statesmen, using exaggerated and a style full of praise; but in his ghazals he writes classic ghazal style and tells as to be in love and enthusiastic words. In his Dîvân, there is no mystical maning of this word. Heart which deal with a variety of interest of the meaning is extased, in love and a mirror showing the beauty lover. In this article, detail definitions of heart concept with various sources will be analyzed together with meanings of words and evaluated by statistical methods. Gönül, klasik edebiyat şairlerinin, divanlarında en çok rastlanan ve işlenen konularından biridir. Kavram sedece klasik edebiyatın değil, halk edebiyatının ve sözlü kültür sahasının da çok işlediği konular arasındadır. Aşk ve âşıklık söz konusu olduğu zaman elbette âşığın gönlü de beyitlerin kelime dünyasında hemen yerini alır. Bu itibarla hangi klasik edebiyat şairinin divanına bakılsa, hemen hemen hepsinde gönül kavramına ait mecazlar ve mazmunlar bulunduğu görülür. XVII. yüzyılın ilk yarısında yaşamış ve bir kaside üstadı olarak şöhret bulmuş olan şair Nef‛î, divanında gönülle ilgili kavram ve benzetmelere yer vermiştir. Kelime, geçiş sıklığı itbariyle daha çok gazellerde yer alır. Kasidelerini genel olarak padişah ve devlet adamlarına ithafen yazan ve mübala

Pseudocalotes rhaegal sp. nov. most likely occurs in syntopy with P. flavigula in Tanah Rata at Cameron Highlands and its discovery adds to a growing body of literature detailing the recent descriptions of several new, upland, closely related, sympatric species in Peninsular Malaysia. Another new population referred to here as Pseudocalotes sp. nov. from the Hala-Bala Wildlife Sanctuary, Betong District, Yala Province, Thailand is discussed. The discovery and description of these three new Pseudocalotes from the upland regions of Peninsular Malaysia continues to underscore the remarkably high herpetological diversity and ecological complexity in this sky island archipelago that is still underestimated, unappreciated, and unprotected.

    Full Text Available Dans de nombreuses disciplines scientifiques, le discours parlé représente depuis quelques décennies un objet de recherche proéminent. Ce fait s’explique probablement par deux caractéristiques principales du discours parlé: la structure complexe de sa matérialité et les fonctions variées de différentes pratiques langagières. C’est pourquoi le présent numéro réunit les articles basés sur les approches actuelles du discours parlé et sur les pratiques langagières spécifiques. Le volume est introduit par deux articles interdisciplinaires: Peter Garrard et Ahmed Samrah présentent le domaine de la pathologie du langage en donnant une revue fouillée sur les approches actuelles de l’analyse linguistique lors de la détection de la maladie d’Alzheimer, tandis que Harry Hollien donne un aperçu structuré sur le domaine de la phonétique judiciaire destiné à dévoiler l’identité des locuteurs et de détecter la déception dans le discours parlé. Les analyses explorant l’acquisition du langage commencent par l’article de Katharina Zipser qui examine la progression de structures grammaticales en les mettant en comparaison avec la compétence des apprenants et continuent par l’étude de Meta Lah proposant une évaluation des documents audiovisuels proposés aux apprenants de langue étrangère. Vesna Požgaj Hadži, Damir Horga et Tatjana Balažic Bulc remettent en question la corrélation entre la compétence linguistique et la fluence linguistique auprès de locuteurs non-maternels et l'analyse de Gemma Santiago Alonso aborde l'acquisition de l'article défini dans le langage enfantin.

    Djerdap hinterland. The fourth shared characteristic which links these settlements is their dominant position in the landscape. Given that their position and appearance are readily visible from a considerable distance, they probably were not used for hiding, but for making their position prominent. We suppose that pastoral communities emphasized in this manner their control of mountain crosspass and roads, particularly in places where rivers exit narrow canyons in important communications paths to the Crni and Beli Timok, Pek and Danuber rivers. The other Coţofeni-Kostolac type settlement on the territory of north-eastern Serbia is represented by settlements that are positioned on smaller hills or on gentle slopes that on the average range between 336 and 210 m above sea level. The only fortified hill fort settlement discovered so far, Čoka lu Balaš near Krivelj (Map 1/3 belongs to this group. The archaeological sites Velika Čuka i Neresnica (Map 1/23, Smiljkova glavica in Štubik (Map 1/31 and Ćetaće in Kovilovo (Map 1/38 are located on wide and flat, elevated plateaus that dominate up on river valleys. Judging by the considerable surface that they occupy, their position and surroundings for these two settlements, we can suppose that they could have been used for wintering places or points for gathering of flocks and shepherds during pauses between seasonal migrations. They are primarily characterized by the natural surroundings of smaller hills and larger river valleys, as well as the relatively low above sea level elevation on which they are located. Such “seasonal stations or checkpoints” on which larger groups of shepherds could gather with their flocks during the winter months represented important locations in the lives of pastoral communities. During the warm summer period, homesteads with stable architecture are abandoned because of migrations into mountain areas, where favourable grazing areas area located. Certain groups of shepherds during autumn
