Full textAbstract:
Microfinance has spread rapidly since the 1970s and gained a lot of international attention. Advocates mean it is a good way to reduce poverty, but still there is no consensus within the research about the impacts of microfinance and its contribution to poverty reduction.The aim of this study is to assess the members’ perceptions about the impacts of the rural member-based microfinance institutions (MFIs), Savings and Credit Cooperative Societies (SACCOS) and Village Community Bank (VICOBA), on members’ socio-economic situation as well as their perceptions about the contribution to poverty reduction and to identify potential obstacles. The study is mainly based on individual semi-structured interviews with members of SACCOS and VICOBA conducted between February and April 2012 in Babati district Tanzania and earlier research and studies within the area of microfinance and poverty reduction make up the theoretical framework. There is a general agreement among the members interviewed that these MFIs have positive impacts on their socio-economic situation. The results show that it helps to meet consumption needs, pay school fees, run small businesses, increase and diversify the income and the majority also believes that it can be a useful tool for poverty reduction. However, it doesn’t lead to poverty reduction automatically, it depends on how the loans are used and this study identifies several obstacles for SACCOS and VICOBA to be more effective and contribute more to poverty reduction. The main obstacles found are low repayment status, lack of capital and lack of education in both entrepreneurship and how these MFIs operate.

Full textAbstract:
Tanzania has in the recent years kept a steady economic growth and the poverty rate has fallen significantly. At the same time, informal financial services have increased in popularity as a tool for poverty reduction. Previous research claims that gender equality will progress when economic development is taking place. But despite the economic development, the situation for Tanzanian women is still tough and the man is considered to be the head of the household. This paper aims to show why Tanzania is a deviant case regarding economic development and gender equality, and investigate how informal financial services impact women empowerment, by looking at membership in Village Community Banks. Feminist theories are used to explain why economic development and gender equality does not always have a linear relationship. It is concluded that membership in Village Community Banks have impacted the women on a personal level, enhancing self-confidence and belief. However, the gender equality within the household is not progressing due to a patriarchal social ordering, where the male is superior and the female inferior. It is not enough to focus on financial services, such as access to savings and credit, for a woman to be empowered enough to become equal to her husband.

Memoria para optar al Titulo Profesional de Médico VeterinarioEl objetivo de este trabajo fue caracterizar la gestación en la vicuña (Vicugna vicugna) mantenida bajo condiciones de manejo en semicautiverio, mediante la determinación de la fertilidad y la definición de la curva de crecimiento embrio-fetal, por medio de la ecografía transrectal y la medición de las concentraciones plasmáticas de progesterona materna. El estudio se realizó en el predio Ancara, ubicado en la localidad de Chislluma, comuna de General Lagos, I Región de Tarapacá. El rebaño en estudio estuvo constituido por 45 vicuñas adultas. Luego del diagnóstico de gestación, se seleccionaron 12 hembras en las que se realizaron exámenes ecográficos donde se midió el diámetro biparietal (DBP), altura de tórax (AT) y diámetro abdominal (DA) fetales y se tomaron muestras de sangre materna para la medición de concentración plasmática de progesterona. Estos procedimientos se realizaron cada 2 meses, hasta el parto. La medición de la concentración plasmática de progesterona se llevó a cabo mediante radioinmunoanálisis. La fertilidad del rebaño fue de 62%. La concentración plasmática de progesterona fue ≥ 5 nmol/L en hembras preñadas y ≤ 2 nmol/L en hembras secas. El crecimiento de las variables morfométricas fetales se representan mediante las siguientes ecuaciones: EG = 0,2333 + (47,09 * DBP) r² = 0,96 EG = -0,1048 + (50,17 * AT) r² = 0,93 EG = 0,05122 + (36,22 * DA) r² = 0,90 Donde EG es la edad gestacional y se mide en días y DBP, AT y DA en cm. El alto coeficiente de determinación de las características morfométricas fetales permitirán evaluar el crecimiento intrauterino o estimar la fecha probable de parto, cuando no se conoce la fecha de encaste

Full textAbstract:
La vicuña (Vicugna vicugna) es una especie silvestre de Camélido Sudamericano (CSA). Está clasificada en Bajo Riesgo según la IUCN, no obstante, como continúa estando amenazada, se requiere estudios enfocados en su conservación. Una herramienta de conservación es la reproducción asistida, sin embargo, para hacer uso de ella, primero se requiere conocer la fisiología básica de la especie. En ese sentido, el presente estudio tuvo como objetivo desarrollar un protocolo de contención química y colección de semen en vicuñas mediante la técnica de electroeyaculación, así como caracterizar el eyaculado obtenido. Fueron utilizados 9 individuos machos adultos de V. vicugna, clínicamente sanos, pertenecientes al Parque Zoológico Huachipa (n igual 3), Lima; CIP Quimsachata-INIEA (n igual 4), Puno; y Zoológico Municipal Cerrito de La Libertad (n igual 2), Huancayo. La electroeyaculación se realizó bajo anestesia general, utilizando la combinación de ketamina (7,83 mg Kg-1), xilacina (1,20 mg Kg-1) y atropina (0,07 mg Kg-1) (n igual 19), además de midazolam (0,35 mg Kg-1) (n igual 9). La colección de semen (n igual 16) se llevó a cabo con un electroeyaculador que constaba de un transductor rectal de 2 cm de diámetro y 3 electrodos de cobre espaciados por 0,4 cm. El animal fue colocado en decúbito y se le introdujo el transductor rectal lubricado de 10 a 15 cm dentro del recto. El protocolo de electroeyaculación consistió de estímulos progresivos desde los 2 V hasta los 12 V. Fue colectado eyaculado en 15 de los procedimientos. Los valores seminales encontrados son los siguientes (x ± EE): volumen 0,85 ± 0,12 ml; pH 7,09 ± 0,16; motilidad espermática no progresiva 28,08 ± 3,56 %; concentración 166,29 ± 60,92 x 104 espermatozoides/ml y espermatozoides normales 62,77 ± 1,96 %. En cuanto al volumen testicular, el valor total encontrado fue de 22,95 ± 2,28 cm3, el cual no tiene correlación con el volumen seminal y la concentración espermática (r igual 0,06 y r igual 0,16; P menor 0,05). Se concluye que la colección de semen por electroeyaculación en vicuñas es factible, asimismo las características seminales observadas son similares a las otras especies de CSA.The vicuna (Vicugna vicugna) is a wild species of South American Camelid (SAC). From the conservation point of view, is classified at Low Risk by the IUCN. However, it is still a threatened species so many studies for their conservation are required. The assisted reproduction is a conservation tool, however it is necessary to know first the basic physiology of the species. In such sense, the aim of this study was to develop a protocol for chemical immobilization and semen collection using the electroejaculation technique, as well as to characterize the ejaculate obtained. Nine adult males of vicuna, clinically healthy, located at the Huachipa Zoological Park, Lima (n same 3), Quimsachata Research Station, Puno (n same 4) and Zoo Cerrito de La Libertad, Huancayo (n same 2) were used. The electroejaculation procedure was carried out under general anesthesia. The combination of ketamine (7,83 mg Kg-1), xilacine (1,20 mg Kg-1) and atropine (0,07 mg Kg-1) (n same 19) were used, besides of midazolam (0,35 mg Kg-1) (n same 9). Semen collection (n same 16) was carried out with an electroejaculator with a 2 cm diameter probe with 3 ventral electrodes spaced about 0,4 cm. With the animal in recumbent position, the lubricated probe was inserted 10 to 15 cm into the rectum. Progressive electrical stimuli from 2 V to 12 V was applied. Fifteen ejaculates were collected. Seminal values of the ejaculates were as follow (x ± SE): volume 0,85 ± 0,12 ml, pH 7,09 ± 0,16, non progressive sperm motility 28,08 ± 3,56 %; sperm concentration 166,29 ± 60,92 x 104 spermartozoa/ml and sperm normal morphology 62,77 ± 1,96 %. In the case of testicular volume, the total value found was 22,95 ± 2,28 cm3, and do not show correlation with seminal volume and sperm concentration (r same 0,06 y r same 0,16; P less 0,05). These results demonstrate that it is possible to collect semen by electroejaculation and the vicuna´s seminal values are similar with the others (SAC).

Memoria para optar al Título
Profesional de Médico VeterinarioEste estudio tuvo por finalidad evaluar el efecto de la suplementación alimentaria estratégica, sobre la eficiencia reproductiva, en un grupo de vicuñas mantenidas en semicautiverio, en el altiplano de la I región de Chile. Se utilizaron dos grupos de animales: vicuñas con suplementación alimentaria, suministrada en dos momentos críticos para la gestación y un grupo de vicuñas control, que consumieron sólo el alimento proporcionado por la pradera. La primera suplementación alimentaria, se entregó como “flushing” 15 días antes de comenzar el encaste y durante éste, con el fin de estudiar su efecto sobre la tasa de concepción y sobrevivencia embriofetal. El segundo tratamiento nutricional, se administró en los meses de Septiembre y Octubre, momento en el cual las vicuñas cursan su 6º –7º mes de gestación, con el fin evitar los abortos que se detectan en ese período de la preñez. El suplemento administrado consistió en 1 Kg de heno de alfalfa (producido en Putre) por animal, otorgado en comederos colectivos, durante el período previamente descrito. En ambos casos, la presencia de gestación se evaluó mediante ecografías y mediciones de las concentraciones plasmáticas de progesterona. Adicionalmente, las vicuñas se pesaron al inicio y al final de cada tratamiento nutricional, con el fin de determinar el efecto de ellos sobre el peso corporal. El “flushing” de alimentación no tuvo un efecto significativo sobre la tasa de concepción o menor mortalidad embriofetal. Tampoco se observó un efecto sobre el peso corporal. La suplementación nutricional de gestación no produjo diferencias en el número de abortos entre las vicuñas tratadas y control, pero se observó un incremento en el peso de las vicuñas suplementadas. Adicionalmente, se estableció que existen diferencias entre los pesos que logran las vicuñas al inicio de la gestación y que no pierdan su cría en los meses de baja disponibilidad de forraje. Se concluye, que el tratamiento nutricional otorgado, no es efectivo para mejorar la fertilidad en la vicuña. Sin embargo, el incremento del peso de las vicuñas al inicio de la gestación, podría disminuir el número de vicuñas que abortan en la temporada seca. La suplementación durante la época seca del altiplano, es efectiva para aumentar el peso de los animales, pero el efecto sobre un menor número de abortos fue incipiente

A relação entre desnutrição e desenvolvimento cognitivo tem sido amplamente discutida na literatura. Estudos têm demonstrado que crianças que tenham sofrido de desnutrição apresentam atrasos em testes de Quoeficiente Intelectual (QI), dificuldades em áreas do desempenho acadêmico e alterações no comportamento social e emocional, quando comparadas a seus pares eutróficos sem história de déficits nutricionais. O presente trabalho teve como objetivo avaliar o desenvolvimento cognitivo de escolares com déficit ponderal ou estatural e compará-los ao de eutróficos do município de Viçosa Minas Gerais. Foram aferidas medidas De peso e altura das crianças e elas foram divididas em três grupos, de acordo com seu estado nutricional: (15) eutrófico, (15) com déficit ponderal e (15) com déficit estatural O desenvolvimento cognitivo foi avaliado por meio da Escala de Inteligência Weschler para Crianças - Terceira Edição (WISC III). Procurou-se também verificar a hipótese de déficit de atenção entre as crianças com déficit de peso e ou altura, utilizando-se o índice fatorial Resistência à distrabilidade do WISC III. Procurou-se também avaliar a influência da escolaridade e inteligência materna. A inteligência das mães foi aferida pelo teste Matrizes Progressivas de Raven Escala Geral. As crianças com déficit de peso tiveram desempenho inferior às crianças eutróficas para todas as medidas de QI total, verbal e de execução. Por outro lado, as crianças com déficit de estatura somente diferiram das eutróficas com relação ao QI de execução. Não foi possível comprovar a hipótese de déficit de atenção. Inteligência e escolaridade maternas tiveram coeficientes de correlação positivos e significantes com o funcionamento cognitivo infantil. Os resultados demonstram que a desnutrição ainda que não grave é capaz de provocar atrasos no desenvolvimento cognitivo. Além disso, a desnutrição aguda, definida pelo déficit ponderal, tem seus efeitos sobre o funcionamento intelectual, mais pronunciados do que a desnutrição crônica, caracterizada pelo déficit estatural, sugerindo a importância de intervenções que atuem, especialmente de forma preventiva, neste tipo de déficit.
The relation between malnutrition and cognitive development has been widely argued in literature. Studies have demonstrated that children who have suffered from malnutrition present delays in tests of Intellectual Coefficient (IQ), difficulties in areas of the academic performance and alterations in the social and emotional behavior, when compared to their eutrophyc pairs without historical malnutrition.The present studies have the goal to evaluate the cognitive development of students with weight and height deficit and compare them to their eutrophycs in the city of Viçosa - Minas Gerais. Height and weight measurements were taken from the students and the students were divided in three groups, according to their nutritional condition: (15) eutrophyc, (15) with weight deficit and (15) with height deficit. The cognitive development was evaluated through the Weschler Intelligence Scale for children - Third Edition (WISC III). We also try to verify the hypothesis of a deficit in the studentºs ability to pay attention caused by a deficit in height or weight.The Raven Progressive Matrices General Scale, measured the motherºs intelligence. The children with deficit on weight had lower IQ, worse verbal skills and worse action skills. On the other hand, the children with height deficit were only different from the eutrophyc when comparing IQ and action skills. We were not able to prove the hypothesis of deficit in attention. The motherºs intelligence and educational level had positive and significant correlation coefficients with the cognitive development of the children. The results show that malnutrition, even when itºs not in big proportions, can cause delays on the cognitive development. In addition, the acute malnutrition, defined by weight deficit, has its effects over the intellectual functioning stronger than the chronic malnutrition, which comes with height deficit, suggesting that interventions are important and need to be made especially to try to prevent other than combat the problem, in this kind of deficit.

Tesis para optar al grado de Magíster en Literatura mención Literatura Chilena e HispanoamericanaEl trabajo que presentamos aborda algunos aspectos que consideramos relevantes de la obra escrita de la creadora chilena Cecilia Vicuña. Mediante un corpus de textos publicados por la autora y seleccionados para este estudio, podemos distinguir una recurrencia temática en su poesía en relación a una indagación originaria y un compromiso con los destinos de la humanidad y la naturaleza, las condiciones de la vida actual y la creciente pérdida de armonía global. Hacernos cargo de algunas de estas preocupaciones vicuñeanas ha requerido identificarlas y exponerlas como núcleos que han caracterizado su propuesta estética, pero sobre todo que señalan una postura ética de la vida. Para Vicuña –y es lo que nos proponemos comprobar aquí–, su poesía es una disposición que recupera un equilibrio y una memoria allí donde se han instalado lo precario y lo fútil, lo evanescente y lo descartable, y que propone una transformación paradigmática del individuo primero y de la sociedad a continuación.

CAPES
In this study the epidemiology, clinical signs, macroscopic and microscopic lesions related to spontaneous and experimental intoxication by Vicia villosa and the evaluation of the possible toxicity of Vicia villosa in cattle were characterized. The systematic granulomatous disease (SGD associated with vetch) was verified in 7 localities distributed in Paran?, Santa Catarina and Rio Grande do Sul States, with main feed that includes oats and/or ryegrass in association and V. villosa and/or ryegrass associated with Vicia sativa, and in lower quantity. All cattle that developed the disease were cows, lactating and Dutch. The SGD associated with vetch was reproduced in six lactating Dutch cows, by supplying green V. villosa in the trough and V. villosa and ryegrass pasture. In the other experimental groups (group 3, V. villosa / V. sativa/cows, grazing; group 4, V. sativa/cows, grazing; group 5, V. villosa/V. sativa/heifers and group 6, V. villosa/heifers, grazing) do not verified clinical and pathological alterations related to the SGD associated with vetch. Six cows developed the SGD, one cow presented a leigh clinical condition (group 2/cow 6/V. villosa, pasture), four cows developed a moderated clinical condition (group 1, cows 1 and 2/V. villosa/trough and group 2, cows 4 and 5/V. villosa, grazing), and just one cow presented a severe clinical condition (group 2, cow 3/V. villosa/pasture. V. villosa was toxic to cattle and produced a chronic granulomatous disease when ingested in amounts greater than 38.2 g/kg/day for 71 days, or in direct grazing for a period of more than 28 days The main clinical signs consisted of alopecia and cutaneous crusts, pruritus, fever, conjunctivitis, diarrhea, reduction of milk production and weight loss. Macroscopically, multiple white-grayish nodules were observed, specifically in the lymph nodes, kidneys and heart, and histology revealed a granulomatous infiltrate composed of macrophages, lymphocytes, giant cells, epithelioid cells, plasma cells and eosinophils. When ingested by young cattle, the V. villosa pasture, for a period of 68 days, do not produce clinical modifications. When ingested by cows with high milk yield, the V. sativa pasture, for a period of 78 days, does not produce chronic granulomatous disease. Ingestion of V. villosa for a long time led to low production rates, such as low milk production, low reproduction rates and predisposition to infection diseases. In the bromatological analysis, the presence of phytate, in low levels, in the samples of Vicia used in experimental works, in different phases of the culture was determined. The biochemical blood and feces results showing lower amounts of serum sinc and loss of Ca and Zn feces in animals poisoned by V. villosa, that developed granulomatous disease in severe and moderate conditions, possibly indicated the presence of a metabolic disorder in the pathogen of the disease.
No presente estudo caracterizou-se a epidemiologia, os sinais cl?nicos, as les?es macrosc?picas e microsc?picas da intoxica??o espont?nea e experimental por Vicia villosa, bem como a avalia??o da poss?vel toxicidade de Vicia sativa em bovinos. A doen?a granulomatosa sist?mica (DGS ervilhaca-associada) foi verificada em 7 propriedades distribu?das nos Estados de Santa Catarina, Paran? e Rio Grande do Sul, onde a alimenta??o principal era aveia e/ou azev?m consorciados com V. villosa e/ou de azev?m consorciado com V. villosa e em menor quantidade V. sativa. Todos os bovinos que desenvolveram a doen?a eram vacas, em lacta??o e da ra?a Holand?s. A DGS ervilhaca-associada foi reproduzida em seis vacas holandesas em lacta??o, atrav?s do fornecimento de V. villosa verde no cocho e em pastagens de V. villosa e azev?m. Nos demais grupos experimentais (grupo 3, V. villosa/V. sativa/vacas, pastejo; grupo 4, V. sativa/vacas, pastejo; grupo 5, V. villosa/V. sativa/novilhas e grupo 6, V. villosa/novilhas, pastejo) n?o verificou-se altera??es cl?nicas e patol?gicas relacionadas a DGS ervilhaca-associada. Das seis vacas que desenvolveram a doen?a granulomatosa sist?mica, uma vaca apresentou quadro cl?nico leve (grupo 2/vaca 6/V.villosa, pastejo), quatro vacas desenvolveram o quadro moderado da doen?a (grupo 1, vacas 1 e 2/V. villosa/cocho e grupo 2, vacas 4 e 5/V.villosa/pastejo) e apenas em uma vaca verificou-se o quadro grave da doen?a (grupo 2, vaca 3/V.villosa/pastejo). V. villosa foi t?xica para bovinos, produzindo doen?a granulomatosa cr?nica quando ingerida em quantidades superiores a 38,2g/kg/dia, por um per?odo de 71 ou, em pastoreio direto por um per?odo superior a 28 dias. As principais manifesta??es cl?nicas consistiam em ?reas de alopecia e crostas na pele, coceira, febre, conjuntivite, diarreia, queda na produ??o de leite e perda de peso. Macroscopicamente verificaram-se m?ltiplos n?dulos branco-acinzentados principalmente em linfonodos, rins e cora??o, e na histologia estes caracterizavam um infiltrado granulomatoso composto por macr?fagos, linf?citos, c?lulas gigantes, c?lulas epitelioides, plasm?citos e eosin?filos. As pastagens de V. villosa quando ingerida por bovinos jovens, por um per?odo 68 dias n?o produziu altera??es cl?nicas. As pastagens de V. sativa quando ingerida por vacas de alta produ??o leiteira por um per?odo de 76 dias n?o produziu doen?a granulomatosa cr?nica. A ingest?o de V. villosa por per?odos prolongados conduziu a baixos ?ndices produtivos como: baixa produ??o leiteira, baixos ?ndices reprodutivos e pode predispor o surgimento de doen?as infeciosas. Na an?lise bromatol?gica determinou-se a presen?a de fitato, em pequenas quantidades, nas amostras de Vicia utilizadas na experimenta??o, em diferentes fases do seu crescimento. Os resultados das an?lises bioqu?micas de amostras de sangue e fezes evidenciaram baixas quantidades s?ricas de zinco e excessivas perdas fecais de Ca e Zn nos animais intoxicados por V. villosa que desenvolveram a doen?a granulomatosa na forma moderada e grave, indicando um poss?vel envolvimento de dist?rbios de ordem metab?lica na patogenia da doen?a.

Sem bolsa
La empresa Vicoza S.R.L. fue creada en el año 1987, con la finalidad de comercializar semillas de especies forrajeras, las cuales son importadas de Brasil y comercializadas mediante representación exclusiva de la marca MATSUDA en Paraguay. Se colectaron datos oficiales de importación de semillas de especies forrajeras, del periodo 2008 al 2012, de la Asociación de Productores de Semillas del Paraguay para determinar la participación en el mercado, y datos internos de la empresa, como ser cantidades de semillas de especies forrajeras importadas anualmente por especie, variedad y valor cultural, las cuales han sido comparadas con la cantidad facturada en concepto de semillas de especies forrajeras por año. Se asignó una categoría para los tipos de clientes, resultando en directos e indirectos. Los clientes directos son productores ganaderos y los indirectos los distribuidores (cooperativas y reventas). Fue obtenida la eficiencia de forma anual. Se ha desarrollado un plan anual de marketing. El trabajo tuvo por objetivo el análisis de los resultados de la introducción de la tecnología de semillas incrustadas entre los productos comercializados por la empresa, realizando un análisis con los datos tomados de la misma, que ayude en la toma de decisiones y la formación de criterios y estrategias para mejorar las ventas. Al finalizar la evaluación, se puede concluir que la empresa mostró una capacidad limitada de aprovechar las mejoras tecnológicas, a falta de una investigación más profunda y ausencia de la regularidad, para lograr la aceptación de la tecnología de semillas de forrajeras incrustadas por parte de los clientes. No obstante, han sido descriptas las acciones correctivas y las estrategias a poner en práctica para lograr corregir la situación y se lleguen a los objetivos y metas establecidas para lograr el éxito de la empresa.

Full textAbstract:
Die Arbeit liefert eine Gesamtinterpretation des geschichtsphilosophischen Klassikers von Giovanni Battista Vico "Prinzipien einer neuen Wissenschaft über die gemeinsame Natur der Völker" (1744).
Neben einer Interpretation des verum-factum-Prinzips als erkenntnistheoretische Grundlage des Werks und einer Rekonstruktion seines Geschichtsbildes schließt die Dissertation einen Vorschlag
zur ideengeschichtlichen Einordnung Vicos sowie eine Diskussion der Aktualität seiner Geschichtsphilosophie ein.
Es wird gezeigt, dass die rezeptionsgeschichtlich tonangebenden idealistischen und theologischen Interpretationsansätze dem Werk unangemessen sind. Als Alternative wird eine naturalistische Lesart entwickelt.
Diese lebensrealistische Lesart zielt auf den Nachweis ab, dass Vico den menschlichen Geschichtsprozess als evolutionären und zugleich sinnvollen Vorgang begreift, dessen Ziel im
Überleben der menschlichen Gattung besteht.
Vicos Theorie der geschichtlichen Selbstregulierung stellt hierbei die symbolische und soziale Produktivität des Menschen als körperliches Naturwesen ins Zentrum, wobei die Entstehung von sozialen Institutionen und
symbolischen Weltbildern als nicht-intendiertes Resultat subjektiv-sinnlicher Handlungsmotive begriffen wird.
Detailliert herausgearbeitet wird die Leitidee Vicos, dass soziale Institutionen durch vorrationale Fiktionen stabilisiert werden, die der menschlichen Einbildungskraft entspringen.
Insofern sind es soziale Mythen, die die Gesellschaft zusammenhalten.
Mit der Orientierung seines systemtheoretisch angelegten Geschichtsdenkens an menschlichen Überlebensfragen vertritt Vico einen Standpunkt, der bis heute nichts Aktualität verloren hat.

El Toxoplasma gondii es un protozoo, que tiene como hospedero definitivo a los felinos y como hospederos intermediarios, a un amplio rango de hospederos entre ovinos, caprinos, porcinos, aves y humanos. Este protozoo, presenta una distribución mundial y es causante de problemas reproductivos en el ganado, principalmente el ovino. Su importancia radica en la implicancia zoonótica. Los estudios realizados en camélidos sudamericanos silvestres como la vicuña son escasos, sobre todo aquellos dirigidos a determinar los problemas de tipos reproductivos y epidemiológicos. El objetivo del presente estudio fue estimar la seroprevalencia de T. gondii en vicuñas de la Reserva Nacional de Pampa Galeras, en el Departamento de Ayacucho, para lo cual se muestrearon 191 vicuñas, entre machos y hembras, a las cuales se les realizó la prueba de Inmunofluorescencia indirecta. La seroprevalencia obtenida fue de 5.8 ± 3.3 %, no observándose diferencias estadísticas significativas en los resultados, al evaluar las variables sexo y grupo etáreo relacionados a los reactores a la prueba serológica. El presente estudio demuestra la infección por T. gondii en vicuñas de la Reserva Nacional de Pampa Galeras-Proyecto San Cristóbal y Aledaños.
Palabras Clave: Toxoplasmosis, CSA silvestre, serología, anticuerpos, Ayacucho.--- Toxoplasma gondii is a protozoan parasite, which definitive host is the feline and has a wide range of species like sheep, goats, pigs, birds and humans as intermediate hosts. This protozoan is worldwide distributed and causes reproductive problems in cattle, specially sheep. Its importance takes root in its zoonótica implication. Studies performed in wild South American camelids like the vicunas are scarce, specially those directed to determine reproductive and epidemiological problems. The objective of this study was to determine the Seroprevalence of T. gondii in vicunas of the National Reserve of Pampa Galeras in the department of Ayacucho. Therefore, 191 serum of vicunas were evaluated, male and female, by using the inmunofluorescent antibody test (IFAT). The Seroprevalence obtained was 5.8 % +/- 3.3. Significant statistical differences were not observed in the results, comparing the variables age and sex. The present study demonstrates that infection of T. gondii in vicunas of the National Reserve of Pampa Galeras occurred. Key Words: Toxoplasmosis, wild SC , serology, antibodies, Ayacucho.

Full textAbstract:
La toxicité cellulaire potentielle de la sulcotrione 2-(2-chloro-4-(methylsulfonyl)benzoyl)-1,3-cyclohexanedione, un herbicide sélectif tricétonique a été évaluée sur Vicia faba et Allium cepa. La génotoxicité a été étudiée sur une culture hydroponique pour des traitements à différentes concentrations de sulcotrione 10-5, 10-4 et 2.10-4 M pendant 45 h. Nos résultats ont montré que la sulcotrione provoque une augmentation dose-dépendante de la fréquence des micronoyaux dans les cellules méristèmatiques des racines. Elle induit des altérations chromosomiques à la concentration la plus faible (10-5M) mais aussi une baisse de l’indice mitotique, ce qui indique l'effet mutagène puissant de cette molécule. C’est le premier travail montrant une génotoxicité de la sulcotrione. Les signes d’intoxication se manifestent par les perturbations de la croissance foliaire et racinaires accompagnées d’un brunissement des racines traitées de Vicia faba. Sulcotrione, Mikado®, marc de raisin et des mélanges de sulcotrione ou Mikado® et de marc de raisin induisent la mort cellulaire. La présence des herbicides ainsi que celle des cocktails ont entrainé l’installation d’un état de stress oxydant caractérisé par une production accrue d’H2O2. La production de radicaux d’oxygène actif s’accompagne d’une augmentation de la production de MDA et un accroissement de la mort cellulaire. L’ajout de l’extrait de raisin aux herbicides, soit à la sulcotrione ou au Mikado®, modifie l'expression des gènes habituellement associés au stress cellulaire. Les cocktails et les herbicides modifient l’expression des gènes hsp70.1, cat, ubiquitin, APX, CuZnSOD cy et CuZnSOD ch. Des mécanismes de défense, d’induction de gènes associés au stress et de génotoxicité sont discutésPotential cell toxicity of sulcotrione 2-(2-Chloro-4-(methylsulfonyl)benzoyl)-1,3 cyclohexanedione), a selective triketonic herbicide was evaluated on Vicia faba and Allium cepa . Genotoxicity was studied in hydroponic culture conditions for treatment at different pesticide concentrations 10-5, 10-4 and 2.10-4 M for 45 h. Our results showed that sulcotrione treatments caused a dose dependent increase of micronucleus frequencies in root meristematic cells. Sulcotrione induced chromosomal alterations at the lowest concentration used (10-5M) when incubated for 42 h. We have shown a decrease in mitotic index, indicating a potent mutagenic effect of this element. This is the first report for the genotoxicity of such a sulcotrione herbicide. It induced a growth inhibition in both leaves and roots and a brownish color in treated roots. Sulcotrione, trade mark Mikado®, grape marc and mixtures of sulcotrione or Mikado® and grape marc induce cell death. The herbicides, cocktails of products with sulcotrione, such as adjuvant in commercial product, induced several changes for antioxidant cell state characterized by an overproduction of H2O2. Production of harmful radicals was accompanied by increased production of MDA and increase of the cell death rate. Addition of grape extracts to herbicides, either sulcotrione or Mikado®, had different effects and results in different expression of genes usually associated to cell stress. Mixture of grape marc and herbicides enhanced transcript accumulation for different effects and results in different expression of some stress-related genes like hsp70.1, cat, ubiquitin, APX, CuZnSOD cy et CuZnSOD ch. Mechanisms which could be associated to gene expression, cell defense and genotoxidity are discussed

This article will center on the impact of the work La revolución de la independencia del Perú (Lima, 1860) by the Chilean historian Benjamín Vicuña Mackenna (Santiago, 1831-1886). It will discuss the novelty of the use of the term «revolution» in an age in which Peruvian historiography rejected the political use of that term. It will then discuss the reception of Vicuña’s work in Peruvian historiography in the nineteenth and twentieth centuries. In particular, it underlines the reasons why this work was not included as a supporting text in the formation of the nationalist discourse of the Peruvian state.Este artículo se concentra en el estudio del impacto del libro La revolución de la independencia del Perú (Lima, 1860) del historiador chileno BenjamínVicuña Mackenna (Santiago, 1831-1886).

Memoria para optar al Título profesional de
Ingeniero AgrónomoEl presente estudio se efectuó con el objetivo de evaluar el comportamiento agronómico de tres cultivares de haba de crecimiento determinado establecidos en dos fechas de siembra (1° de mayo y 8 de junio) de 2007, en la Zona Central de Chile. Cada fecha de siembra fue establecida como un ensayo independiente, y cada ensayo contó con tres tratamientos correspondiente a los cultivares Retaca, Alargá y Verde Bonita. Las mediciones fueron realizadas sobre parámetros de crecimiento y rendimiento. Para evaluar el crecimiento se efectuaron muestreos en los estados de inicio de floración, inicio de llenado de granos y precosecha, determinándose en cada uno de ellos la altura de planta, número de nudos vegetativos a primera flor, número de ramas por planta y número de nudos vegetativos y reproductivos por cada rama y eje principal. Al momento de la cosecha se evaluó el rendimiento en vaina y en grano por planta, además de los componentes primarios del rendimiento como lo son el número de vainas por planta, número de granos por vaina y peso de 100 granos verdes. Se midió además el rendimiento industrial y algunos parámetros de calidad tales como largo y ancho de vainas y de granos comerciales, evaluándose además visualmente el color de los granos al momento de la cosecha. El número de nudos vegetativos, en el eje central se mantuvo estable en ambas fechas de siembra; en cambio, parámetros como altura, nudos reproductivos en el eje principal y nudos vegetativos y reproductivos en las ramas, sí presentaron diferencias significativas entre las dos fechas evaluadas. A nivel de rendimiento también se observaron diferencias significativas entre ambas fechas de siembra, siendo la segunda fecha la que generó valores más altos, presentado diferencias de un 14% para vainas y de 22,5% para granos. Retaca, por su parte fue el cultivar que presentó el mayor, y significativamente mejor rendimiento en ambas fechas de siembra.
The following study aims to evaluate the effect that two sowing dates have on three determinate growth broad bean cultivars. The research took place in Central Zone of Chile. The dates May 1st and June 8th were used as independent for the three the cultivars, Retaca, Alargá and Verde Bonita. Measurements were taken for the parameters of growth and performance. The index used for growth were the onset of flowering, the onset of grain formation and pre-harvest. For each sample, the number of vegetative knots at first flower, the height and number of branches for each plant and the number of vegetative and reproductive knots for each branch and main axle was measured. At harvest time, pod and grain performance were evaluated for each plant; moreover, primary indicators of performance, such as the number of pods per plant, number of beans per pod and weight of 100 unripe beans were also evaluated. Other evaluated parameters were industrial performance, length and height of the pods and commercial-viability of the beans, with the later also being evaluated on the colour they presented at harvest time. The number of vegetative knots in the main axle remained stable for both of the two sowing dates. Conversely, parameters such as height, reproductive knots in the main axle and vegetative and reproductive knots of branches did present significant differences between the two dates evaluated. The pod and bean performance per plant presented significant differences: the second sowing date generated significantly higher values presenting differences of 14% for pods and 22.5% for beans. With respect to the differences between the cultivars, Retaca presented the best optimum combination of all behaviours: it presented significant differences to the other cultivars in both sowing date samples.

Full textAbstract:
Die Fähigkeit, mit anderen Zellen zu kommunizieren, ist eine grundlegende Eigenschaft aller lebenden Zellen und essentiell für die normale Funktionsweise vielzelliger Organismen. Die Speicheldrüsen der Schmeißfliege Calliphora vicina bilden ein ausgezeichnetes physiologisches Modellsystem um zelluläre Signaltransduktionsprozesse an einem intakten Organ zu untersuchen. Die Speichelsekretion wird dabei hormonell durch das biogene Amin Serotonin (5-Hydroxytryptamin; 5-HT) reguliert. 5-HT aktiviert in den sekretorischen Zellen der Drüsen über die Bindung an mindestens zwei membranständige G-Protein gekoppelte Rezeptoren (GPCR) zwei separate Signalwege, den IP3/Ca2+- und den cAMP-Signalweg.
Zur Identifizierung und Charakterisierung der 5-HT-Rezeptoren in den Speicheldrüsen von Calliphora wurden unter Anwendung verschiedener Klonierungsstrategien zwei cDNAs (Cv5-ht2α und Cv5-ht7) isoliert, die große Ähnlichkeit zu 5-HT2- und 5-HT7-Rezeptoren aus Säugetieren aufweisen. Die Hydropathieprofile der abgeleiteten Aminosäuresequenzen postulieren die für GPCRs charakteristische heptahelikale Architektur. Alle Aminosäuremotive, die für die Ligandenbindung, die Rezeptoraktivierung und die Kopplung an G-Proteine essentiell sind, liegen konserviert vor. Interessanterweise wurde für den Cv5-HT7-Rezeptor eine zusätzliche hydrophobe Domäne im N Terminus vorhergesagt. Die Cv5-HT2α-mRNA liegt in zwei alternativ gespleißten Varianten vor.
Mittels RT-PCR-Experimenten konnte die Expression beider Rezeptoren in Gehirn und Speicheldrüsen adulter Fliegen nachgewiesen werden. Ein Antiserum gegen den Cv5-HT7 Rezeptor markiert in den Speicheldrüsen die basolaterale Plasmamembran.
Die Expression der Rezeptoren in einem heterologen System (HEK 293-Zellen) bestätigte diese als funktionelle 5-HT Rezeptoren. So führte die Stimulation mit Serotonin für den Cv5-HT2α zu einer dosis-abhängigen Erhöhung der intrazellulären Ca2+ Konzentration ([Ca2+]i, EC50 = 24 nM). In Cv5-HT7-exprimierenden Zellen löste 5-HT dosisabhängig (EC50 = 4,1 nM) einen Anstieg der intrazellulären cAMP Konzentration ([cAMP]i) aus. Für beide heterolog exprimierten Rezeptoren wurden pharmakologische Profile erstellt. Liganden, die eine Rezeptorsubtyp-spezifische Wirkung vermuten ließen, wurden daraufhin auf ihre Wirkung auf das transepitheliale Potential (TEP) intakter Speicheldrüsenpräparate getestet. Drei 5-HT-Rezeptoragonisten: AS 19, R-(+)-Lisurid und 5-Carboxamidotryptamin führten zu einer cAMP-abhängigen Positivierung des TEP durch eine selektive Aktivierung der 5 HT7-Rezeptoren. Eine selektive Aktivierung des Ca2+-Signalweges durch den Cv5-HT2 Rezeptor ist mit Hilfe von 5-Methoxytryptamin möglich. Dagegen konnte Clozapin im TEP als selektiver Cv5-HT7-Rezeptorantagonist bestätigt werden.
Die Kombination eines molekularen Ansatzes mit physiologischen Messungen ermöglichte somit die Identifikation selektiver Liganden für 5-HT2- bzw. 5-HT7-Rezeptoren aus Calliphora vicina. Dies ermöglicht zukünftig eine separate Aktivierung der 5-HT-gesteuerten Signalwege und erleichtert dadurch die weitere Erforschung der intrazellulären Signalwege und ihrer Wechselwirkungen.Cellular communication is a fundamental property of living cells and essential for normal functioning of multicellular organisms. The salivary glands of the blowfly Calliphora vicina are a well established physiological model system to study cellular signaling in an intact organ. Fluid secretion in this gland is hormonally regulated by the biogenic amine serotonin (5-hydroxytryptamine, 5-HT). In the secretory cells, 5-HT causes a parallel activation of the InsP3/Ca2+- and the cAMP-signaling pathways through binding and stimulation of at least two G protein coupled receptors (GPCR). In order to characterize the respective 5-HT receptors on the secretory cells, we have cloned two cDNAs (Cv5-ht2α, Cv5-ht7) that share high similarity with mammalian 5-HT2 and 5-HT7 receptor classes. Analysis of the deduced amino acid sequences postulates the typical heptahelical architecture of GPCRs for both receptors. Sequence motifs that are essential for ligand binding, receptor activation and coupling to G-proteins are well conserved. Interestingly, a computer-based structural analysis of Cv5-HT7 predicts an additional eighth hydrophobic region in the N-terminus of the receptor. We also found an alternative splice variant of the Cv5-HT2α mRNA. Using RT-PCR experiments, transcripts of both receptor mRNAs could be detected in brain and salivary gland tissue. An antiserum raised against the Cv5 HT7 receptor stained the basolateral region of the salivary glands. Heterologous receptor expression in HEK 293 cells leads to a dose-dependent increase in the intracellular Ca2+-concentration ([Ca2+]i) for Cv5-HT2α (EC50 = 24 nM) and cAMP-concentration for Cv5-HT7 (EC50 = 4,1 nM) upon application of 5-HT. A pharmacological profile was established for both receptors. Ligands that appeared to act as specific ligands of either Cv5-HT2α or Cv5-HT7 in this approach, were then tested for their effect on the transepithelial potential (TEP) of intact blowfly salivary gland preparations. Three 5-HT receptor agonists: AS 19, R-(+)-lisuride and 5-carboxamidotryptamine showed a cAMP dependent positivation of the TEP, caused by a selective activation of the Cv5-HT7 receptor. 5-methoxytryptamine exclusively activates the Ca2+ pathway via Cv5-HT2α. Clozapine antagonizes the effects of 5-HT in blowfly salivary glands and was confirmed as a Cv5-HT7 antagonist. The combination of a molecular approach with physiological measurements enabled us to identify selective ligands for 5-HT2 and 5-HT7 receptors of Calliphora vicina. These results facilitate a selective activation of the intracellular signaling pathways activated by 5-HT and will facilitate future research on different aspects of intracellular signaling and crosstalk mechanisms.

Vico s Scienza nuova introduces a proposal to science the Vico Variable which is clearly different from the prevailing variable, that of Modern Science as we understand it today, based on Newton s Mechanicism and in Descartes Rationalism, anchored in the Enlightenment of the 18th century and established, once and for all, in Comte s Positivism. In Vico, metaphysics no longer busies itself with the contemplation of and speculation about God, to bring its focus down to earth and seek, in History, that which had, until then, sought in the Divine Mind. To him, the knowledge of human affairs is that which can answer the question characteristic of all times concerning what Man is. The civil world of the Scienza nuova develops in the metaphysical realm, to whose study the new art of criticism is developed: a synergy between philosophical criticism and philological investigation, leading to Vico s hermeneutics, which takes advantage both of Reason and of the faculties of the spirit. In this hermeneutics, microcosm and macrocosm, man and society, particular and universal, are synthesized in constant analogies; the theory of the verum ipso factum is originally applied and the common sense of humanity becomes the supreme objective principle of historic evolution (a manifestation of Divine Providence) and as a subjective ground of a historic understanding. So as to situate nations in the development of the eternal ideal history , to evaluate its degrees of civility and the risks it is subject to, the Scienza nuova proposes, also, a diagnostic art, from which one may criticize the way which knowledge (Science and Education) is considered by the moderns in this time. Such criticism is not restricted to observations and considerations, but it sets the groundwork for an action it is, therefore, a Political Science through the proposal of a focus that is able to overcome the empire of the Mathesis Universalis, and thus, to contemplate, equally, the possibility of knowledge of the Ethical, Political and Human universes, interacting in a selfsame science. The Vico Variable is not only a way that has been forsaken on the road of the development of science; something which might have been. It is a philosophical orientation which privileges the practical life, the understanding of human behavior and civil life, which can be extended to thinkers who came after Vico, whose ideas allow the identification with outstanding aspects of his thought; a philosophical orientation which, identified with the emphasis Pico della Mirandola gave upon the Dignity of Man, can represent the emancipation of humanity
A Scienza nuova de Vico apresenta uma proposta para a ciência a Vertente Vico que é notadamente diversa da vertente prevalente, ou da ciência moderna como a entendemos hoje, baseada no mecanicismo de Newton e no racionalismo de Descartes, firmada no iluminismo do século XVIII e sacramentada no positivismo de Comte. Em Vico, a metafísica deixa de ocupar-se com a contemplação e especulação sobre Deus para trazer seu foco para a terra e buscar na história aquilo que buscava até então na mente divina. O conhecimento das coisas humanas é que pode responder à questão característica de todas as épocas sobre o que é o homem. O mundo civil da Scienza nuova, desenvolve-se no âmbito metafísico, para cujo estudo é desenvolvida a nova arte crítica: uma sinergia entre a crítica filosófica e a investigação filológica, constituindo-se na hermenêutica viquiana, que se vale tanto da razão, como, igualmente, das faculdades do espírito. Nessa hermenêutica, microcosmo e macrocosmo, homem e sociedade, particular e universal, são sintetizados em analogias constantes; a teoria do verum ipsum factum é originalmente aplicada e o senso comum da humanidade é alçado como princípio objetivo da evolução histórica (manifestação da providência divina) e como fundação subjetiva de uma compreensão histórica. Para situar as nações no desenvolvimento da historia ideal eterna , avaliar seus graus de civilidade e os riscos a que estão submetidas, a Scienza nuova propõe, também, uma arte diagnóstica, a partir da qual são empreendidas críticas à maneira como o conhecimento (ciência e a educação) é considerado pelos modernos de sua época. Tais críticas não se detém em observações e considerações, mas lançam as bases de uma ação numa ciência também política, portanto através da proposta de um enfoque que supere o império da Mathesis Universalis para contemplar, igualmente, a possibilidade de conhecimento dos universos ético, político e humano, interagindo numa mesma ciência. A Vertente Vico não é apenas uma via preterida no caminho do desenvolvimento da ciência; algo que poderia ter sido. Mas é uma orientação filosófica que privilegia a vida prática, a compreensão do comportamento humano e o viver civil, que pode ser estendida até pensadores posteriores a Vico, cujas ideias permitem a identificação com aspectos destacados do pensamento viquiano; uma orientação filosófica que, identificada com a ênfase de Pico dela Miràndola sobre a dignidade do homem, pode representar a emancipação da humanidade

El presente proyecto de negocio consiste en instalar una planta industrial textil para el lavado y descerdado de fibra de vicuña en el Perú y con ello iniciar un círculo virtuoso de beneficios en diferentes stakeholders a lo largo de la cadena de valor de este producto. La fibra de vicuña es conocida en el mundo textil mundial como el insumo más exclusivo de prendas de lujo, por su fineza y escaso volumen. El Perú genera el 80% de la producción mundial pero en el mercado internacional coloca el 90% de esta producción sin procesar. Esta nítida oportunidad fue analizada y se determinó que en Italia existe una sola empresa que realiza todos los procesos de la cadena de valor, lo que condiciona el libre acceso al insumo por parte de otras firmas textiles de élite. Se identificó a dos clientes interesados en el producto limpio, cuyas principales exigencias son el cumplimiento del tiempo de entrega, volúmenes asegurados y sostenibles en el tiempo. Ello implica, por un lado, instalar la planta industrial con tecnología especializada para procesar fibra de vicuña y, de otro lado, organizar la oferta de la materia prima a nivel de los proveedores que habitan de manera dispersa en los Andes por encima de los 4.500 msnm. Así también se deberá lograr el cumplimiento de las certificaciones y permisos para usufructuar este producto, que está clasificado como mercancía restringida, por tanto, regulada por el Estado debido a la condición de silvestría de la vicuña, expuesta al peligro de extinción por la caza furtiva. Por ello, se han identificado los diversos aspectos que permitan optimizar los procesos, ubicando la planta en la ciudad de Juliaca (frontera con Bolivia) porque conglomera la producción de fibra del Sur del Perú y de Bolivia de los mayores proveedores de este producto.

After situating Vico in the Naples of his time and in relation to the questions of modern rationality, as well as carrying out an exercise of philosophical reflection seeking the understanding of the worldview of Vico, this piece of work aims at making explicit the ethic that underlies his work as an ethic of teleological character which privileges the practical life, evidencing a concern for what man can and should do of himself, notwithstanding the guardianship of a divine providence in a cyclical history. However, within the advent of the "age of men," it is verified a process of unfoldment of the human nature in which the development of the individual starts to dictate the development of the community; at the same time, the predominance of abstract rationality dissociated from other human faculties – such as imagination – leads to a preponderant literality in the interpretation of mythology, which pervades the doctrines of religions, moving man away from piety, with the consequent loss of both social cohesion and the human sense of the world. Hence, man decays in the age of the gods, submitting himself to heteronomy in the face of the eternal ideal history. It is identified with the present thesis, therefore, the "master key" indicated by the Napolitan himself with the imagination that underlies poetic wisdom, the application of this interpretative key of the method of his work – the new critical art – is extended to the solution of the pretended paradox between the autonomy and the aimed happiness by a teleological ethic and the cyclical repetition of the eternal ideal history
Após situar Vico na Nápoles de seu tempo e em relação às questões da racionalidade moderna, e realizar um exercício de reflexão filosófica para a compreensão da cosmovisão viquiana, objetiva-se explicitar a ética que subjaz em sua obra como uma ética de caráter teleológico e que privilegia a vida prática, evidenciando uma preocupação para com o que o homem pode e deve fazer de si mesmo, nada obstante a tutela de uma providência divina numa história cíclica. Entretanto, no advento da “idade dos homens”, verifica-se um processo de desdobramento da natureza humana em que o desenvolvimento do indivíduo passa a ditar o desenvolvimento da comunidade; ao mesmo tempo, a predominância da racionalidade abstrata dissociada de outras faculdades humanas, como a imaginação, conduz a uma literalidade preponderante na interpretação da mitologia, que pervade as doutrinas das religiões, afastando o homem da piedade, com a consequente perda da coesão social e perda do sentido humano do mundo. Daí, o homem decai na idade dos deuses, submetendo-se à heteronomia face a história ideal eterna. Identifica-se com a presente tese, então, a “chave mestra” indicada pelo próprio Napolitano com a imaginação que fundamenta a sabedoria poética, estende-se a aplicação dessa chave interpretativa do método de sua obra – a nova arte crítica – para a solução do pretenso paradoxo entre a autonomia e a felicidade objetivada por uma ética teleológica e a repetição cíclica da história ideal eterna

L'ensemble de l'étude est articulé en quatre parties. La 1ère partie se penche sur l'inventio des deux cités par Augustin d'Hippone, du De vera religione au De civitate Dei, en offrant une étude détaillée des enjeux politiques et théologiques de cette notion et du lexique augustinien à cet égard. La IIe partie examine la diffusion de ce paradigme dans la culture médiévale, à travers l'analyse des textes exégétiques y ayant recours entre le 6e et le 12e s. Cette même partie pointe plusieurs distorsions et innovations propres à la vie médiévale de la ciuitas diaboli (y compris l'invention médiévale de la ciuitas infernalis). Dans la Ille partie, il est question des usages actualisant la ciuitas diaboli en vue de la représentation de l'histoire contemporaine. Cela à travers plusieurs études de cas entre le Ile et le 14e s. Et notamment du Carmen in victoriam Pisanorum, du Speculum Ecclesiae, du De incendio oppidi Tuitii de Rupert de Deutz, d'une fectio de Joachim de Flore sur les sens de Jérusalem et Babylone, des œuvres de Dante Alighieri, enfin des traductions à la fin du 14e s. Du De ciuitate Dei (en français par Raoul de Presles et en florentin).

Le catalogue des manuscrits en annexe complète le travailMy PhD dissertation consists in a longue durée study of the codification, diffusion, reinvention and iconographical representation of the "civitas diaboli's paradigm", as I defined it in the Prologue, in western medieval culture. The dissertation is articulated in four parties. The first one concerns IWO cities' inventio by Augustine of Hippo, sin ce De vera religione to De civitate Dei. It offers a detailed investigation of political and theological significations of this notion and of Augustinian vocabulary on il. The second part examines civitas diaboli's widespread diffusion in medieval culture, by analyzing exegetical works recurring to it between 6th and 12th century. Many different distortions and innovations of medieval civitas diaboli are pointed out (as for instance medieval invention of a civitas infernalis). The third part focuses on sorne actualizing civitas diaboli's applications to the contemporary history between nth and 14th century. More particularly, the Carmen in victoriam Pisallorum, the Speculum Ecclesiae, the De incendia oppidi Tuitii by Rupert of Deutz, a lectio by Joachim of Flore on Jerusalem and Babylon, Dante's works and, finally, De ciuitate Dei's translations in French, by Raoul of Presles, and in Florentine at the end of the 14th century are taken into account. The fourth part offers the first study of ail the two cities' representations in the illuminated manuscript tradition of the De ciuitate Dei as weil as of its translations in vernacular.

Full textAbstract:
This dissertation discusses whether Giacomo Leopardi (1798-1837) can be considered a philosophical heir of Giambattista Vico (1668-1744), as some scholars retain, despite the fact that there is no evidence that Leopardi read Vico’s New Science or other works until late (1828); too late to demonstrate a direct influence of the philosopher’s thought on the deepest nexuses of Leopardi’s reflection. This dissertation clarifies how Leopardi responded to Vico-related questions characterizing the culture of his time through an innovative methodology that looks at the diffraction of Vico’s ideas in Bourbon Restoration Italian culture. This work aims to paint a dynamic picture of Italian nineteenth-century polycentric culture through a geographical organization of the material; it in fact tackles the diffusion of Vico’s works and ideas from Naples to Venice (Chapter 1), to Milan (Chapter 2), to Leopardi’s hometown Recanati (Chapter 3), to Florence (Chapter 4), and again to Naples (Chapter 5). Not only does this work shed new light on the existence of a Vico-Leopardi philosophical lineage, but it also present an original study of perceptions of time and history and of the dichotomy ancient/modern in Post-Napoleonic Italian culture.

Telaye, Asfaw. "Pollen physiology and fertilisation in Vicia faba L." Thesis, Durham University, 1990. http://etheses.dur.ac.uk/5960/.
Full textAbstract:
Abstract In many legume crop species, early-formed fruits or those located closest to the photosynthate are more likely to mature than other fruits. This is so in the Vicia faba crop. Based on physiological, nutritional and genetical aspects of seed development, several hypotheses are documented. However, Vicia faba pollen fertility has not been adequately studied. Thus, a series of experiments, consisting of studies of both in vitro and in vivo pollen viability, pollen tube growth and fertilisation ability were conducted using highly inbred lines (6-13 generations). Some of the in vivo experiments were conducted under Ethiopian field conditions. In some lines, even a low level of stress at 20 ºC for 4h at 100% relative humidity (RH) caused a dramatic drop in mean percent pollen germination. The overall results indicated that there was considerable variation (p≥0.001) among the Hues studied, in response to high temperature (20 to 35 C) and 100% RH. Vicia faba pollen showed high variability in fertility level. Overall significant differences exist in fertility (p≥0.01) among the genotypes studied. A fertility gradient exists along the stem: in most genotypes the fertility declining towards the upper nodes. In all of the genotypes, the first nodes carried more highly fertile pollen than the middle and the last flowering nodes. Also the middle nodes were more highly productive than the last nodes in all the genotypes. Thus, success of fertilisation depends to a degree on the source of pollen used. In an experiment concerning pollen storage, freshly dehiscent anthers desiccated at 25 C/6h and freeze dried for 45min, stored in either LN2 or at -80 ºC, gave more than 80% viability after 9 months of storage. Desiccation at RT for 24h and storage in either LN2 or at -80 C and at -20 C, still maintained pollen viability ≥80%. Mixed pollination studies conducted indicated that pollen from one or other of each pair of inbred fines, mixed on an equal weight basis, performed better as pollen parents on some maternal fines than on others. The importance of these findings with respect to synthetic variety and hybrid seed production in the text is discussed. The probable existence of genetic self-incompatibility is also discussed.

Full textAbstract:
This thesis presents the first monographic taxonomic treatment of Vicia in South America, in which 20 native species are recognized. In addition to an identification key, the taxonomic account provides full synonymy, and for each species a detailed description, distribution map, notes on distribution, habitat, phenology and an IUCN conservation assessment. Vicia buchtienii P.Hechenleitner is described as new, V. bidentata Hook. is reinstated as a separate species, and the new combination of V. bonariensis (Burkart) P.Hechenleitner is made. Fifteen names are newly reduced to synonymy, 23 lectotypes are chosen, and one neotype is proposed. Four of the 20 species are considered endangered. South American Vicia species are assigned to section Australes. Based on Bayesian and parsimony analysis of DNA sequence data from chloroplast (matK and psba-trnH) and nuclear ribosomal internal transcribed spacer (ITS) sequences representing 50% of the species of Vicia in South America, sect. Australes is shown to be paraphyletic. If classification is to reflect monophyly, sect. Australes should be expanded to include three north and central American species that are nested within it. The phylogenetic results suggest a single origin of Vicia in South America resulting from long-distance dispersal from North America. A densely sampled species-level phylogeny of sect. Australes was estimated using nuclear (ITS) and chloroplast (psbA-trnH) regions analysed using Bayesian and parsimony approaches. Fourteen of the 20 South American Vicia species were included, many represented by multiple accessions, resulting in the most comprehensive phylogenetic study of the section to date. Vicia minutifora D.Dietr. is the probable sister to the remaining species in sect. Australes, and the lack of geographic structure in the phylogeny implies repeated dispersal events within South America. By revealing three probable new species from Peru and Bolivia, the phylogeny indicates the utility of combining phylogenetic and morphological analyses in the delimitation of closely related species.

Le Myo-inositol hexakisphosphate (phytate), principale composante de P organique (Po) du sol, représente une potentielle source de P disponible du sol, bio-disponible pour la plante, en lien à des activités phytases microbiennes, minéralisatrices du phytate. Afin de rechercher des rhizobiums, symbiontes de Vicia faba, efficaces dans l’utilisation du P (EUP) pour la FSN, nous avons réalisé un diagnostic nodulaire multilocalisé, en agro-écosystèmes sud de France. Le niveau d’efficacité d’utilisation de la symbiose rhizobienne (EUSR), en intra- et inter-placettes agricoles et en conditions hydroaéroponiques en serre, a été déterminé en corrélation des biomasses aériennes et nodulaires de plants de V. faba, à floraison. Parmi 59 isolats de V. faba, 26 sont aptes à minéraliser le phytate (Phy +), en milieu solide et six d'entre eux confirment une activité phytase, en culture liquide.

However, associated with biotic constraints (i) missing and/or (ii) phosphorus (P) deficiency, can limit symbiotic nitrogen fixation (SNF). Myo-inositol hexakisphosphate (phytate), the main soil organic P (Po) component, represents a potential source of soil P available for plant P bio-availability, connected with microbial phytate-mineralizing activities. In order to look for rhizobium-Vicia faba, in P use efficiency (PUE) for SNF ability, nodular diagnosis was performed from a multi-location survey in an agro-ecosystem in South France. The efficiency in use of rhizobial symbiosis (EURS) was deduced from V. faba nodule and shoot dry weight values at flowering state, and compared in intra- and inter agricultural fields and in greenhouse hydroaeroponic conditions. Among 59 V. faba isolates, 26 were able to mineralize phytate (Phy+) in solid medium and six of them confirmed phytase activity in liquid culture. Looking for local rhizobiums with PUE for SNF ability, led us to a forward step in molecular marker selection for Phy+ rhizobium isolate screening.

Vicia villosa foi relacionada a intoxicações em bovinos e causa uma doença granulomatosa sistêmica caracterizada por lesões de pele e múltiplos nódulos esbranquiçados em vários órgãos. Nesse trabalho realizou-se a intoxicação experimental por sementes e folhas de V. villosa em coelhos e bovinos. Os coelhos que receberam 5g/kg de sementes de ervilhaca apresentaram lesões descamativas e crostosas nas orelhas e evidenciação dos tecidos linfóides do intestino. Os coelhos intoxicados por folhas de ervilhaca e que receberam a aplicação para o teste de hipersensibilidade apresentaram evidenciação dos tecidos linfoides do intestino que corresponderam na histologia a infiltrado de histiócitos, linfócitos e células gigantes multinucleadas. O bovino alimentado com sementes de ervilhaca (5g/kg) não apresentou a doença clínica. Na intoxicação experimental por folhas de V. villosa, o bovino não apresentou sinais clínicos, porém houve aumento nodular dos linfonodos que, na histologia, demonstravam infiltrado granulomatoso. Cinco casos de intoxicações naturais por V. villosa foram diagnosticados no Setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (SPV-UFRGS) no período de 2005 a 2010. As principais alterações macroscópicas observadas foram lesões alopécicas e crostosas de pele e múltiplos nódulos branco-acinzentados principalmente localizados nos linfonodos, rins e coração. Na histologia dos animais intoxicados visualizava-se macrófagos, linfócitos, células epitelioides e células gigantes multinucleadas, plasmócitos e eosinófilos. A intensidade do infiltrado granulomatoso variou entre os cinco casos analisados e entre os órgãos de cada animal. Os testes imuno-histoquímicos caracterizaram os infiltrados, que foram constituídos principalmente por linfócitos T e macrófagos. Os resultados dos testes de hipersensibilidade cutânea em bovinos com extratos protéicos da planta sugerem que os animais com a doença clínica apresentam uma resposta de hipersensibilidade tardia enquanto que os demais animais modulam a resposta imune diferentemente.Vicia villosa was associated with poisoning in cattle, causing a systemic granulomatous disease. Hairy vetch poisoning is characterized by skin lesions and multiple whitish nodules in several organs. This work reports experimental poisoning by seeds and leaves of V. villosa in rabbits and cattle and the spontaneous poisoning by V. villosa in cattle is described. Rabbits received 5g/kg of seeds of hairy vetch and presented scaly, crusted lesions in ear and enlargement lymphoid tissue of intestine. Rabbits poisoned by hairy vetch leaves that were tested for cutaneous hypersensitivity showed enlargement of intestine lymphoid tissue. The histologic feature of this, lesion consisted of granulomatous inflammation. Cattle fed with seeds of hairy vetch (5g/kg) did not have clinical disease. Experimental poisoning by leaves of V. villosa in cattle did not present clinical signs; however, nodules in lymph nodes were observed. Histologically, infiltration of macrophages, lymphocytes and multinucleated giant cells were observed. Five cases of poisoning by V. villosa in cattle were diagnosed at Setor de Patologia Veterinária of Universidade Federal do Rio Grande do Sul (SPV-UFRGS) in the 2005 to 2010 period. Gross lesions were alopecia, skin crusts and multiple nodules mainly located in lymph nodes, kidneys and heart. Microscopically, infiltration of lymphocytes, macrophages, multinucleated giant cells, plasma cells and eosinophils were observed. Intensity of granulomatous infiltration varied among the five cattle and between analyzed organs. The inflammatory infiltration was characterized by immunohistochemistry. It was mainly composed of lymphocytes T and macrophages. Cutaneous hypersensitivity tests with hairy vetch proteins suggest that cattle with clinic disease have type-IV hypersensitivity reaction while others show different immune response.

Resumo: Vico criticou a racionalidade de seu tempo e propôs outra como alternativa: a chave para essa questão é o conceito de engenho. Em seu programa pedagógico, Vico aspirava a uma síntese entre ciência, prudência e eloqüência, e sugeriu que isso seria possível aguçando-se o engenho dos jovens. Vico não é um irracionalista. Sua noção de razão tem raízes humanistas. Ele pretendeu superar a razão cartesiana, reafirmando a tópica, a inventio e a fantasia, para coroar o engenho com o estatuto de faculdade certa do conhecer. Isso permitia-lhe aprofundar-se no estudo das humanidades. Vico condenou o caráter monástico e solitário das filosofias da virada da século XVII para o XVIII, e alertou para o mal do "egoísmo racional" que acometia a sociedade de sua época. Vico não é um pensador solitário. Antes de vê-lo como um precursor ou conservador, é melhor situá-Io em seu próprio tempo, respondendo às últimas novas da república das letras de então. O empenho de contribuição que Vico enfatizou em suas preleções foi posto em prática no contexto da célebre Querela entre Antigos e Modernos, mais especificamente acerca da questão do status de Homero - um problema que solicitou, entre outras coisas, o engenho de Vico. Os quatro aspectos do engenho, a agudeza, a inventividade, a prudência cidadã e a presença histórica, lançam luz sobre a racionalidade pensada por Vico
Abstract: Vico has criticized the rationality of his time and he proposed another one as alternative: the key for this question is the concept of wit. Into his pedagogical program, Vico wished a synthesis among science, prudence, and eloquence. He suggested that it would be possible if one sharpen the young men's wit. Vico is not na irrationalist. His notion about the reason has humanist roots. He intended to overcome the Cartesian reason, in reaffirming the science of topical, the inventio, and the phantasy to enthrone the wit with a right faculty status of knowing. That allows him to make a profound study of the humanities. Vico has condemned the monachal and solitarian feature of the philosophies from the turn of the XVII century to XVIII century, and he prevented us against the evil of the "rational selfish" that society from his time was taken with. Vico is not a solitary thinker. Before seeing him as a forerunner or conservator, it is rather situate him in his own time, answering the last news of the republic letters since that time. The interest of the contribution that Vico emphasized in his discourses was put in practice into the context of the famous Quarrel between the Ancients and the Moderns, more specifically about the question of the Homer's status - a problem that demanded from Vico his wit. The four aspects of the wit, the acuity, the inventiveness, the citizeness prudence, and the historical presence, bring under light the rationality that was thought by Vico

Some morphological characters were used to understand whether they have a diagnostic
value or not. These characters, which include habit, leaf, stem, inflorescence, calyx,
corolla and style properties, were compared at infrageneric level and species level.
Systematic value of pollen micromorphology, trichome micromorphology and petal
epidermal micromorphology of Vicia in Central Anatolia were observed. Pollen grains
equatorial view, polar view and exine ornamentations, trichome types of calyces and
leaves can be useful for separating the species in sectional level.
Geographical and ecological distributions maps were updated. In addition to this, the
conservation status of the genus Vicia in Cental Anatolia was reassessed at regional
level. The threat categories include 2 taxa DD, 1 taxon CR, 7 taxa EN, 1 taxon VU, 1
taxon NT and 14 taxa LC. The main threat categories for this genus are identified as
overgrazing, constructions, land clearing and urbanizations.
The infrageneric delimitations were performed by the use of multivariate analysis.
Identification keys for sections and species were also given. Synonym, species updated
descriptions, phenology, habitat, distribution in Central Anatolia, distribution in Turkey
and general distribution, phytogeograpy, endemism, specimen citations photographs of
species and distribution maps were also indicated.
