Prevalência, intensidade de infecção e variação estacional de helmintos em caprinos no estado do Piauí.

No periodo de julho/77 a agosto/79, estudou-se a epidemiologia das helmintoses em 52 caprinos sem raça definida (SRD) criados extensivamenteno municipio de Valença do Piaui, atraves do exame de ovos por grama de ovos por grama de fezes (OPG), coprocultura e necropsias mensais em animais infectados naturalmente sendo 26 com idade de 3 a 6 meses e 26 com 9 a 12 meses. Os helmintos identificados foram: Heamonchus contortus, Trichostrongylus colubriformis, T. axei, Cooperia curticei, C. punctata, C. pectinata, Strongyloides papillosus, Oesophagostomum columbianum, Trichuris ovis, Trichyris sp., Moniezia expansa e Cysticercus tenuicollis. Os helmintos que ocorreram, em media, com maior intensidade e frequencia foram, respectivamente: H. contortus (697, 6 e 92, 3%,T. colubrifromis (340,5 e 86,4%) e O. columbianum (53,7 e 96,1%). Os dados de OPG indicaram aumento do nivel de infecção por Strongyloidea durante a época chuvosa. As necropsias revelaram que os caprinos são parasitados por helmintos durante todo o ano e, mais especificamente na epoca chuvosa

Mies: Competitions in Friedrichstrasse

Mies participó en una docena de concursos de arquitectura entre los años 1910 y 1934. En siete ocasiones en emplazamientos situados en el área más céntrica y comercial de Berlín –todas en un área de radio menor a un quilómetro– cuatro veces sobre la misma calle Friedrichstrasse incluso, en dos ocasiones, sobre el mismo emplazamiento. Ahora teniendo la historia completa y con el tiempo transcurrido es factible ver, anticipados en estos concursos, aspectos de su proyectar posterior. La relación entre las propuestas de concurso y lo que efectivamente ejecuta en el plano profesional da la medida de sus anhelos latentes en cada momento –diferencia que va disminuyendo progresivamente conforme pasa el tiempo–. Con 24 años había participado en un concurso importante, el monumento a Bismarck en el año 1910, y dos años más tarde en una competición encubierta para la residencia de los Kröller–Müller, en Wassenaar. Ahora bien, son los concursos de Berlín los que le dan oportunidad de encarar proyectos de relevancia urbana. Este artículo aborda las primeras veces que Mies tiene ocasión de reflexionar sobre la relación entre el edificio y su entorno en la ciudad.Mies participated in a dozen architectural competitions between 1910 and 1934. On seven occasions these competitions involved locations in the most central area of Berlin, all in an area of less than a mile radius, four times on Friedrichstrasse and twice on the same site. Now, with the full story and the fullness of time, it is feasible to see aspects of his later career anticipated in these competitions. The relationship between the competition proposals and what he actually implemented on the professional level is a measure of his latent desires at each moment, a difference that gradually diminished with the passage time. At 24 years of age he had participated in a major competition, the Bismarck memorial in 1910, and two years later in a private competition for the Kröller-Müller family residence in Wassenaar. Nevertheless, it was the Berlin competitions that gave the opportunity of addressing important urban projects. This article discusses the first occasions that Mies reflected on the relationship between the building and its surroundings in the city

Severe birth prematurity : a case study of a boy’s psychoeducational support needs

Abstract: This study conducted research related to severe premature birth and the neurodevelopmental disorders that may be associated with it. Severely premature born children, born before the gestational age of 28 weeks, are at an increased risk of developmental delays. These delays may manifest as physical difficulties, learning disabilities, attention deficits, hyperactivity, and behavioural and social problems. Learners with barriers to learning present challenges for teachers due to these developmental delays and comorbid disorders associated with premature birth. The challenges are further intensified by large class sizes, and limited resources. Teachers are generally ill-equipped to meet the demands of the learners in an inclusive situation, in diverse classrooms. It is difficult to differentiate the content and the pace of the curriculum. This study explored the psycho-educational support needs of Lebo (pseudonym), who was born severely premature. The study was conducted in a LSEN class in a mainstream primary school in the south of Johannesburg. ..M.Ed. (Inclusive Education

Spotted Fever Group Rickettsiae, Rickettsia Parkeri And Candidatus Rickettsia Andeanae , Associated With The Gulf Coast Tick, Amblyomma Maculatum Koch

The public health and veterinary importance of Gulf Coast ticks, Amblyomma maculatum Koch (1844) have become more apparent during the last several decades. In addition, new records of this three-host ixodid tick presently show a geographic distribution throughout much of the southern United States. Rickettsia parkeri, a spotted fever group rickettsia (SFGR) that is commonly found infecting the Gulf Coast tick, was only recently recognized as a human pathogen. Over the last decade, more than 20 human cases of disease caused by R. parkeri have been recognized in the Americas, all of which were similar in presentation to mild Rocky Mountain spotted fever. In addition, a novel, poorly characterized SFGR, “Candidatus Rickettsia andeanae”, was recently identified in A. maculatum from Peru, United States, Chile and Argentina. As the recognition of R. parkeri as a pathogen and “Ca. R. andeanae” as an additional SFGR in A. maculatum only recently occurred, a general gap exists in our understanding of the biology of these SFGRs. The overall objective of this dissertation was to contribute to our knowledge of SFGR infecting A. maculatum. In Chapter 3, we present a prevalence study of R. parkeri, and “Ca. R. andeanae” in A. maculatum from Mississippi where we detected 15.2% R. parkeri-singly infected ticks and 3.1% total “Ca. R. andeanae” infected ticks of which 1.7% were co-infected with R. parkeri. In Chapter 4, we discuss finding four genetically different populations of A. maculatum from Mississippi infected with a homogenous population of R. parkeri, using Single Strand Conformation Polymorphism analysis. Those initial data relating to “Ca. R. andeanae” provided a foundation for studies described in Chapters 5 and 6. We report the first morphological study of “Ca. R. andeanae” using transmission electron microscopy in Chapter 5 and isolation of this SFGR in ,A. maculatum cell co-culture in Chapter 6. We anticipate that results presented in this dissertation will contribute to our understanding of the ecology of ,A. maculatum as a vector for the human pathogen, R. parkeri, and increase the current understanding of both R. parkeri and “Ca. R. andeanae” in A. maculatum

Produtividade de caprinos da raca Bhuj.

Durante dois anos (1976/1977) estudou-se o comportamento produtivo de um rebanho de caprinos da raca Bhuj, formado por 28 matrizes e um reprodutor e criado em regime de pasto nativo. A percentagem de femeas paridas no primeiro e segundo ano, em relacao ao numero de femeas do rebanho foi de 143% no no primeiro ano e 125% no segundo, com uma proporcao relativa ao sexo, de 51% para machos e 49% para femeas. A ocorrencia de abortos foi 18%, sendo verificada apenas no primeiro ano. O indice de mortalidade atingiu 16,9% em caprinos jovens e 8,9% em adultos
