The effects of rain and fallen debris on macroinvertebrate colonization of artificial water tanks and their implications for bromeliad communities
Authors: Monge-Najera Julián , Gename Kyle 
Published: June 2019

RESUMEN: Las bromelias son componentes importantes de los bosques tropicales y sus hojas forman tanques con microecosistemas únicos. Hasta hace poco no había estudios experimentales de cómo llegan los macroinvertebrados a esos tanques. Colocamos 150 vasos plásticos ("bromelias artificiales") en un bosque de Costa Rica y hallamos que cuando se evita experimentalmente la caída en ellos de residuos y lluvia, algunos grupos no se encuentran (incluyendo Culicidae, un grupo de importancia médica) o difieren en frecuencia entre tratamiento y control.PALABRAS CLAVE: ecología tropical, experimentos con bromelias, Culicidae en tanques artificiales, Costa Rica, colonización de microhábitats

Published: June 2019

RESUMEN: El maní (Arachis hypogaea) es afectado por varios vertebrados pero hay muy pocos estudios sobre este tema en América Central. Evaluamos el daño causado por la rata de campo (Sigmodon hirsutus) durante dos ciclos de producción (2006-2007) en la Estación Experimental Fabio Baudrit, ubicada en La Garita, Alajuela, Costa Rica. Recolectamos roedores cada mes con trampas de golpe. Para el momento de la cosecha se hizo una recolecta completa de la producción en parcelas de 2 y 3 metros de longitud. Se clasificaron las vainas en grandes, medias y pequeñas, y se evaluó el daño causado por los roedores en cada categoría. Las vainas tuvieron pesos promedios de 2,8, 1,8 y 1,1 g para los tamaños referidos, en el primer ciclo, y de 2,9, 2,1 y 1,3 g para un lote, y de 2,8, 2,1 y 1,3 g para el otro lote en el segundo ciclo. Estimamos una intensidad de daño de 5,28% para el primer ciclo, y ninguno en el segundo ciclo. Concluimos que el daño producido por S. hirsutus se puede reducir al realizar la cosecha en diciembre.

Phenolic resin derived from Jatropha curcas seed-husk lignin as phenol substitute
Authors: Vega-Aguilar Carlos Alberto , Lutz Giselle , Mata-Segreda Julio F. 
Published: June 2019

Phenolic resin derived from Jatropha curcas seed-husk lignin as phenol substitute. A phenolic resin was made, with a fraction of the phenol content substituted by lignin extracted from Jatropha curcas seed husk. The husk was analysed for chemical composition, finding a high quantity of lignin (47% mass fraction). This lignin was extracted using an alkaline pulping method, followed by precipitation with acid. Several lignin-modified phenolic resins were made, using different lignin contents, in mixtures with formaldehyde in alkaline conditions, and curing at 65 ºC for 6 hours. It was noticed that the lignin substitution percentage affects the resin’s mechanical properties, obtaining better results with a 50% substitution. These resins showed good thermal behaviour, electrical insulation properties and good physical stability against water, acidic solutions and organic solvents, but it lacked on stability against alkaline solutions. It is concluded that there is a good opportunity for using the J. curcas seed husk lignin as partial substitute of phenol in phenolic resins, without sacrificing their physicochemical properties. There is a wide range of possibilities on using J. curcas agro-industrial residues as a renewable feedstock.

Con la implantación del Espacio Europeo de Educación Superior (EEES), una de las cuestiones más relevantes que se incluyen en la formación universitaria es el manejo de las nuevas Tecnologías de la Información y la Comunicación (TIC) por parte del alumnado. En esta investigación se ha evaluado el uso de las TIC en 79 estudiantes (Medad=20,43, DT=3,83) de primer curso de Pedagogía de la Universidad de Málaga, y se han analizado las diferencias de género en el ámbito tecnológico. Para la recogida de datos se usó un cuestionario tipo Likert que recababa información sobre las características sociodemográficas y sobre el conocimiento y uso de las TIC. Los resultados muestran una clara diferencia de género en el conocimiento y manejo de las herramientas tecnológicas más complejas, siendo las mujeres las que tienen un conocimiento más escaso. Por otra parte, los resultados muestran que los estudiantes que usan las aulas informáticas universitarias presentan mejores habilidades en el funcionamiento de los foros universitarios que los estudiantes que no usan dichas aulas, independientemente de que sean hombres o mujeres.

<em>This research investigated the design of the overhead crane supports with capacity of 2 x 20 ton. The crane design was modeled using both solids and surfaces, and the analysis was performed with finite element method. The results from the analysis verified the stress level, deflection level from crane column and runway beam, and the critical load of buckling for crane column to prevent the structure failure. The stress level result was compared to the material yield strength to find out whether or not the design is safe. It is concluded that the stresses arising from the rail beam and column are still within the permissible limits so that the design is safe to use. </em>

Este artigo trata da expansão do terceiro setor, verificada nas duas últimas décadas.Esta expanção pode ser atribuída a duas diferentes ordens de razões:a) a adoção de um conjunto de prescrições que datam dos anos 1940,que segundo Anderson (1996, p. 9) constituem uma reação teórica e política veemente contra o Estado intervencionista e de Bem-Estar Social; b) a transferência do atendimento das demandas sociais ao chamado “setor público não estatal”, ou terceiro setor, sob o argumento de que este é, supostamente, o espaço propício à realização plena da “cidadania”.
The Role of Banks and Stock Market in the German Economy
Authors: Zaritskiy B. E. 
Published: June 2019

Relevance.The purpose of this article is to analyse particular features of the modern situation in of the banking and stock market sectors of the Federal Republic of Germany. Some of the topical characteristics of the development of the German banking system during the last years are as follows: The restructuration of the Lands Banks, which was in the centre of the financial crisis of 2008–09; Continuing attempts to reorganise the Deutsche Bank which was and is in continued failure of profits; The decrease in inter-banking credits on the background of expected abandonment of the policy of “quantitative easing”. On the other hand, following a series of unlucky attempts by Deutsche Boerse to establish an alliance with the largest World’s Stock Exchanges, Frankfurt hope to get even with London and become European “financial capital” after Brexit completed.Methods.By analysis of publications edited by EU, ECB, Bundesbank, related German agencies, and also books and articles written by Russian and foreign authors this text demonstrates the changes within the structure of the German banking sector and the strong and weak aspects of the stock market of this country. The author used system’s approach and historical and statistical methods to allow the making of a holistic analysis of the selected topic in its development, as well as ranging statistical data properly and drawing up some conclusions regarding the eventual scenario of further development.Results.This research provided a background for the conclusion that the world financial and economic crisis of 2008–09 has more strongly affected the German banking sector than in former considerations. The leading banking institutions of the country such as Deutsche Bank and Commerzbank are in a hard financial situation. Relatively limited capital adequacy and low level of profitability of the majority of German banks represent important limits for its international activities. Meanwhile, the German stock market remains underdeveloped and therefore plays a subordinated role in financing companies.Prospects.The outcomes of this research could be useful for the assessment of long-term perspectives of the socioeconomic and innovative development of Germany which remains the biggest economy of the EU.

Objective: To analyze the values obtained by electronic baropodometry in patients with metatarsalgia. Methods: A retrospective observational study of medical data (gender, height, weight, body mass index, foot laterality, shoe size and clinical diagnosis) and values obtained by static electronic baropodometry (load distribution and maximum and mean pressure) was performed. A total of 39 patients with clinical complaints of metatarsalgia were selected and subjected to static electronic baropodometry. Results: Female gender was more prevalent (58.9%) among patients, and 61.53% of the patients were overweight or obese. The mean maximum pressure was 1.76kgf/cm2, and the forefoot-to rearfoot load distribution ratio was 0.86. There was a significant correlation between body mass index and maximum pressure. No correlation was found with shoe size. Conclusion: The baropodometry values measured in this study were similar to those reported in the literature. Obese and overweight patients had a higher maximum pressure value, which suggests a higher risk of metatarsal pain in this population.

Authors: Cazar Marcelo 
Published: June 2019

El análisis y diagnóstico de las alteraciones dentofaciales, constituye la base del tratamiento ortodóntico quirúrgico de las deformidades del macizo facial desde un abordaje funcional para llegar a lo estético mediante herramientas clínicas y tecnológicas como son estudios de imagen: cefalometria, tomografías haz de cono y modelos estereolitograﬁcos. El estudio de la estética facial del ser humano ha sido desarrollado desde la antigüedad en base de los canones clásicos, que han marcado como norma en el subconsciente colectivo a los patrones griegos como la norma estándar de belleza facial y que no siempre coinciden con todos los grupos étnicos como es el caso de la sociedad ecuatoriana. El presente trabajo pretende dar al estudiante de pre y pos grado de nuestro medio una metodología para abordar la complejidad del análisis estético dento facial acoplando la interpretación clásica a nuestra multiculturalidad.

Nas construtoras e escritórios de engenharia e arquitetura, geralmente, há grande preocupação em evitar interferências entres os vários projetos que compreendem o planejamento de uma edificação. Assim, é necessário fazer compatibilizações, que hoje em dia, na maioria das vezes, realiza-se pelo software autocad. Tais compatibilizações são necessárias, pois viabiliza a redução de custo da obra de forma que não ocorram gastos com novos materiais, mão de obra e retrabalho. Porém, quando utilizada a plataforma bim para tal, proporciona uma nova experiência, como a agilidade de trabalhar em conjunto para a compatibilização com uma qualidade infindamente melhor. O vigente trabalho, tem como objetivo o estudo de caso dos seguintes projetos: arquitetônico, estrutural, hidrossanitário e elétrico de uma residência unifamiliar que integra o programa minha casa minha vida, da caixa econômica federal, em software revit, bem como a identificação das incompatibilidades entre os projetos citados e as exequíveis soluções, para que viabilize uma nova maneira de compatibilização para os projetos populares com maior qualidade. A planta baixa do projeto arqutetônico foi inserida no software revit®, para inciar as modelagens, servindo como base para os outros projetos. Foi unido em um arquivo os projetos arquitetônico e estrutural, e separado o hidrossanitário e elétrico. Os arquivos foram inseridos no software navisworks, para verificar as incompatibilidades entre os projetos no relatório. As incompatibilidades encontradas foram entre os projetos elétrico e hidráulico, hidráulico e estrutural e elétrico e estrutural. Logo, a plataforma bim é muito necessária para que identifique as incompatibilidades de forma rápida e simples.

L'Education sentimentale : le classement des scénarios

L'Education sentimentale : Le classement des scénarios
Pour bien comprendre la genèse de L'Education sentimentale, il est nécessaire d'identifier les documents qui correspondent à chaque stade de la longue préparation du roman. Connus depuis longtemps, les plans rudimentaires du Carnet 19 (1862) représentent l'embryon primitif du roman. Tandis que les plans rédigés en 1863 ont été perdus, les scénarios dans lesquels Flaubert établit les grandes lignes de son roman au cours du troisième stade préparatoire (1864) ont été conservés. Dans le volume (Bibl. Nat., NA.F. 17611) qui contient la plupart des scénarios du roman les folios 65-104 peuvent être classés comme des 'scénarios d'ensemble' ; écrits avant les autres scénarios, ils couvrent le roman entier. Par contre, les folios 1-64, d'une taille un peu plus grande, peuvent être classés comme des scénarios partiels puisqu'ils couvrent soit une partie entière du roman, soit un chapitre. Certains ont pu être rédigés avant septembre 1864 quand Flaubert a commencé à écrire son roman, d'autres ont été rédigés au fur et à mesure que le roman avançait.
Quant on se rappelle le texte définitif avec toutes ses incertitudes, toutes ses lacunes et toutes ses ambiguïtés, les scénarios peuvent surprendre. Il semble que Flaubert avait besoin de savoir exactement ce qui serait occulté, afin que le caché se voie -en filigrane -à travers l'obscurcissement progressif de l'oeuvre.
Des logements locatifs dans l'espace rural. L'exemple de la Haute-Normandie
Authors: Fruit Jean-Pierre 
Published: June 2019

In France, during the last twenty years, a lot of new houses, mainly privately owned, have been built in the countryside, especially near the towns. As a consequence, 71 per cent of the rural households are owners of their home. Nevertheless, according to a common opinion, it is actually obvious that a large demand in rent-housing is not fulfilled by the offer. In order to check this hypothesis, the local authorities of Haute-Normandie carried on a study, in collaboration with the Geography Department of the Rouen University. Eight cantons have been selected among various types of rural areas, from suburban rural areas to "deep" countryside still largely inhabited by farmers.
In this framework, it has been established that the offer is quantitatively low, especially in council housing, and of poor quality in the predominant private sector. This inadequate offer is facing a strong demand, claiming for more and more comfortable homes. The demand proceeds mainly from young households with low incomes or from elderly retired people but also from teachers, civil servants and other wage-earners whose places of work sustain strong turnover and who can afford rather expensive rents. However, the imbalance between offer and demand leads to expensive rents, even for uncomfortable private houses.
With the help of vacant homes and disused buildings, it would be possible to enlarge the offer, but it would not be sufficient. It was necessary to built new houses for rent of good quality let at reasonable prices, with the help of the current developers of council-housing and also with the help of private developers. This last policy would be the more difficult to enforce. In fact, policies must be adapted to the diversity of rural areas.
L'érosion des terres agricoles en Pays de Caux
Authors: Lechevalier Claude 
Published: June 2019

Water erosion of arable land in the Pays de Caux
Despite moderate geographical (topographical, climatic) conditions, a large area of farmland in the Pays de Caux is today subject to run-off and erosion. The explanation would appear to tie in with the agricultural changes of recent decades. However, although the factors are not difficult to identify, the same effects can be produced by a variety of combinations.
From a long-term point of view, the present situation is the result of a process of readjustment to agricultural changes against a background of Holocene modifications, first natural and later manmade, of the Weichselian landscape. The problem is how to limit and control this process, given the regional socio-economic context.
