Desenvolvimento da oralidade em crianças de três a quatro anos: descrevendo jogos e brincadeiras que produzem novas formas de comportamento

The goal for this communication is the speech development in children three to four years, and how games and child's plays can help them in the process. For this, we have set three specific goals. They are: select games and activities that serve as a means of furthering the development of speech; elect three activities, making sure at what point is the extra step to the outbreak of the sign/symbol and identify at what time of play the child uses more talk and no change in psychological structure. These games have been applied to children from three to four years in order to identify and record their actions and speeches during activities. Acquiring the ability to speak, the kids will be able to communicate socially and develop new forms of behavior. From young children already expresses themselves through babbling and even crying, because do not have a conventional language yet. From the social relationship, the child tends to become familiar with the language, and gradually learn how to use it, expressing her feelings and desires. When the development of language and thought intersect, transform the course of action of the child who begins to have control of your action. Such its importance in society, the language became the basis of childhood education and is the duty of teachers and educators to appropriate the necessary encouragement to the child to develop or improve her language

Analysis of the protective potential of antigens released by Leishmania (Viannia) shawi promastigotes

Leishmania (Viannia) shawi causes cutaneous lesions in humans. Parasite antigens conferring significant protection against American tegumentar leishmaniosis (ATL) might be important for the development of effective vaccine. Therefore, this work evaluates the protective effect of antigenic fractions released by L. shawi. Antigens released by promastigotes to culture medium were concentrated and isolated by SDS-PAGE. The three main fractions LsPass1 (>75 kDa), LsPass2 (75-50 kDa) and LsPass3 (<50 kDa) were electro-eluted according with their molecular mass. Immunized BALB/c mice were challenged with L. shawi promastigotes and the course of infection monitored during 5 weeks. LsPass1-challenged mice showed no protection, however, a strong degree of protection associated to smaller lesions and high expression of IFN-gamma and TNF-alpha by CD4(+) T, CD8(+) T and double negative CD4CD8 cells was achieved in LsPass3-challenged mice. Furthermore, LsPass2-challenged mice showed an intermediated degree of protection associated to high levels of IFN-gamma, IL-4 and IL-10 mRNA. In spite of increased expression of IFN-gamma and TNF-alpha, high amounts of IL-4 and IL-10 mRNA were also detected in LsPass3-challenged mice indicating a possible contribution of these cytokines for the persistence of a residual number of parasites that may be important in inducing long-lasting immunity. Therefore, LsPass3 seems to be an interesting alternative that should be considered in the development of an effective vaccine against ATL.

Pre-and post-puberty physiological plasma oxytocin concentrations in male domestic cats (Felis silvestris catus)

The hormone oxytocin is released by the neuropituitary gland through stimulation of the neurons of the supraoptic and paraventricular nuclei of the hypothalamus. In order to determine the physiological concentrations of this hormone in domestic cats, blood samples were collected from 15 male animals (Felis silvestris catus) during the pre- and post-puberty periods (at four and eight months of age, respectively). Oxytocin determination was accomplished by radioimmunoassay. The average oxytocin concentrations measured in the pre- and post-puberty periods were 2.54±0.24 (μg/dL) and 2.53±0.28 (μg/dL), respectively, and there were no statistical differences between these measurements. Because there are few literature on the analysis of this hormone, especially in the case of male Felis silvestris catus, more studies on the influence of oxytocin on the physiology and reproduction of this species should be conducted under maintenance and situations of stress (such as transportation), and other routine events.

Frequency of Toxocara infection in children attended by the health public service of Maringá, south Brazil.

The lack of specific laboratorial diagnosis methods and precise symptoms makes the toxocariasis a neglected disease in Public Health Services. This study aims to determine the frequency of Toxocara spp. infection in children attended by the Health Public Service of Hospital Municipal de Maringá, South Brazil. To evaluate the association of epidemiological and clinical data, and observational and cross-section study was carried out. From 14,690 attended children/year aged from seven month to 12 years old, 450 serum samples were randomly collected from September/2004 to September/2005. A questionnaire was used to evaluate epidemiological, clinical and hematological data. An ELISA using Toxocara canis larval excretory-secretory products as antigen detected 130 (28.8%) positive sera, mainly between children from seven month to five years old (p = 0.0016). Significant correlation was observed between positive serology for Toxocara, and frequent playing in sandbox at school or daycare center (p = 0.011) and the presence of a cat at home (p = 0.056). From the families, 50% were dog owners which exposed soil backyards. Eosinophilia (p = 0.776), and signs and symptoms analyzed (fever p = 0.992, pneumonia p = 0.289, cold-like symptoms p = 0.277, cough p =0.783, gastrointestinal problems p = 0.877, migraine p = 0.979, abdominal pain p = 0.965, joint pain p = 0.686 and skin rash p = 0.105) could not be related to the presence of anti-Toxocara antibodies. Therefore, two asthmatics children showed titles of1:10,240 and accentuated eosinophilia (p = 0.0001). The authors emphasize the needs of prevention activities.

Influencia de las condiciones de ejecución en la resistencia de anclajes en convencional y autocompactante

A través de los años las estructuras de hormigón armado han ido aumentando su cuota de mercado, sustituyendo a las estructuras de fábrica de piedra o ladrillo y restándole participación a las estructuras metálicas. Uno de los primeros problemas que surgieron al ejecutar las estructuras de hormigón armado, era cómo conectar una fase de una estructura de este tipo a una fase posterior o a una modificación posterior. Hasta los años 80-90 las conexiones de una fase de una estructura de hormigón armado, con otra posterior se hacían dejando en la primera fase placas de acero con garrotas embebidas en el hormigón fresco o barras grifadas recubiertas de poliestireno expandido. Una vez endurecido el hormigón se podían conectar nuevas barras, para la siguiente fase mediante soldadura a la placa de la superficie o enderezando las barras grifadas, para embeberlas en el hormigón fresco de la fase siguiente. Estos sistemas requerían conocer la existencia y alcance de la fase posterior antes de hormigonar la fase previa. Además requerían un replanteo muy exacto y complejo de los elementos de conexión. Otro problema existente en las estructuras de hormigón era la adherencia de un hormigón fresco a un hormigón endurecido previamente, ya que la superficie de contacto de ambos hormigones suponía un punto débil, con una adherencia baja. A partir de los años 80, la industria química de la construcción experimentó un gran avance en el desarrollo de productos capaces de generar una buena adherencia sobre el hormigón endurecido. Este avance tecnológico tenía aplicación tanto en la adherencia del hormigón fresco sobre el hormigón endurecido, como en la adherencia de barras post-instaladas en agujeros de hormigón endurecido. Este sistema se denominó “anclajes adherentes de barras de acero en hormigón endurecido”. La forma genérica de ejecutarlos es hacer una perforación cilíndrica en el soporte de hormigón, con una herramienta especifica como un taladro, limpiar la perforación, llenarla del material adherente y finalmente introducir la barra de acero. Los anclajes adherentes se dividen en anclajes cementosos y anclajes químicos, siendo estos últimos los más habituales, fiables, resistentes y fáciles de ejecutar. El uso del anclaje adherente de barras de acero en hormigón endurecido se ha extendido por todo el espectro productivo, siendo muy habitual tanto en construcción de obras de hormigón armado de obra civil y edificación, como en obras industriales, instalaciones o fijación de elementos. La ejecución de un anclaje de una barra de acero en hormigón endurecido depende de numerosas variables, que en su conjunto, o de forma aislada pueden afectar de forma notable a la resistencia del anclaje. Nos referimos a variables de los anclajes, que a menudo no se consideran tales como la dirección de la perforación, la máquina de perforación y el útil de perforación utilizado, la diferencia de diámetros entre el diámetro del taladro y la barra, el tipo de material de anclaje, la limpieza del taladro, la humedad del soporte, la altura del taladro, etc. La utilización en los últimos años de los hormigones Autocompactables, añade una variable adicional, que hasta ahora apenas ha sido estudiada. En línea con lo apuntado, la presente tesis doctoral tiene como objetivo principal el estudio de las condiciones de ejecución en la resistencia de los anclajes en hormigón convencional y autocompactable. Esta investigación se centra principalmente en la evaluación de la influencia de una serie de variables sobre la resistencia de los anclajes, tanto en hormigón convencional como en un hormigón autocompactable. Para este estudio ha sido necesaria la fabricación de dos soportes de hormigón sobre los cuales desarrollar los ensayos. Uno de los bloques se ha fabricado con hormigón convencional y el otro con hormigón autocompactable. En cada pieza de hormigón se han realizado 174 anclajes con barras de acero, variando los parámetros a estudiar, para obtener resultados de todas las variables consideradas. Los ensayos a realizar en ambos bloques son exactamente iguales, para poder comparar la diferencia entre un anclaje en un soporte de hormigón con vibrado convencional (HVC) y un hormigón autocompactante (HAC). De cada tipo de ensayo deseado se harán dos repeticiones en la misma pieza. El ensayo de arrancamiento de las barras se realizara con un gato hidráulico hueco, con un sistema de instrumentación de lectura y registro de datos en tiempo real. El análisis de los resultados, realizado con una potente herramienta estadística, ha permitido determinar y evaluar numéricamente la influencia de los variables consideradas en la resistencia de los anclajes realizados. Así mismo ha permitido diferenciar los resultados obtenidos en los hormigones convencionales y autocompactantes, tanto desde el punto de vista de la resistencia mecánica, como de las deformaciones sufridas en el arrancamiento. Se define la resistencia mecánica de un anclaje, como la fuerza desarrollada en la dirección de la barra, para hacer su arrancamiento del soporte. De la misma forma se considera desplazamiento, a la separación entre un punto fijo de la barra y otro del soporte, en la dirección de la barra. Dichos puntos se determinan cuando se ha terminado el anclaje, en la intersección de la superficie plana del soporte, con la barra. Las conclusiones obtenidas han permitido establecer qué variables afectan a la ejecución de los anclajes y en qué cuantía lo hacen, así como determinar la diferencia entre los anclajes en hormigón vibrado convencional y hormigón autocompactante, con resultados muy interesantes, que permiten valorar la influencia de dichas variables. Dentro de las conclusiones podemos destacar tres grupos, que denominaremos como de alta influencia, baja influencia y sin influencia. En todos los casos hay que hacer el estudio en términos de carga y de desplazamiento. Podemos considerar como de alta influencia, en términos de carga las variables de máquina de perforación y el material de anclaje. En términos de desplazamiento podemos considerar de alta influencia además de la máquina de perforación y el material de anclaje, el diámetro del taladro, así como la limpieza y humedad del soporte. Podemos considerar de baja influencia, en términos de carga las variables de tipo de hormigón, dirección de perforación, limpieza y humedad del soporte. En términos de desplazamiento podemos considerar de baja influencia el tipo de hormigón y la dirección de perforación. Podemos considerar en el apartado de “sin influencia”, en términos de carga las variables de diámetro de perforación y altura del taladro. En términos de desplazamiento podemos considerar como “sin influencia” la variable de altura del taladro. Podemos afirmar que las diferencias entre los valores de carga aumentan de forma muy importante en términos de desplazamiento. ABSTRACT Over the years the concrete structures have been increasing their market share, replacing the masonry structures of stone or brick and subtracting as well the participation of the metallic structures. One of the first problems encountered in the implementing of the reinforced concrete structures was connecting a phase structure of this type at a later stage or a subsequent amendment. Until the 80s and 90s the connections of one phase of a reinforced concrete structure with a subsequent first phase were done by leaving the steel plates embedded in the fresh concrete using hooks or bent bars coated with expanded polystyrene. Once the concrete had hardened new bars could be connected to the next stage by welding them to the surface plate or by straightening the bent bars to embed them in the fresh concrete of the next phase. These systems required a previous knowledge of the existence and scope of the subsequent phase before concreting the previous one. They also required a very precise and complex rethinking of the connecting elements. Another existing problem in the concrete structures was the adhesion of a fresh concrete to a previously hardened concrete, since the contact surface of both concretes leaded to a weak point with low adherence. Since the 80s, the chemicals construction industry experienced a breakthrough in the development of products that generate a good grip on the concrete. This technological advance had its application both in the grip on one hardened fresh concrete and in the adhesion of bar post-installed in holes of hardened concrete. This system was termed as adherent anchors of steel bars in hardened concrete. The generic way of executing this system is by firstly drilling a cylindrical hole in the concrete support using a specific tool such as a drill. Then, cleaning the bore and filling it with bonding material to lastly, introduce the steel bar. These adherent anchors are divided into cement and chemical anchors, the latter being the most common, reliable, durable and easy to run. The use of adhesive anchor of steel bars in hardened concrete has spread across the production spectrum turning itself into a very common solution in both construction of reinforced concrete civil engineering and construction, and industrial works, installations and fixing elements as well. The execution of an anchor of a steel bar in hardened concrete depends on numerous variables which together or as a single solution may significantly affect the strength of the anchor. We are referring to variables of anchors which are often not considered, such as the diameter difference between the rod and the bore, the drilling system, cleansing of the drill, type of anchor material, the moisture of the substrate, the direction of the drill, the drill’s height, etc. During recent years, the emergence of self-compacting concrete adds an additional variable which has hardly been studied so far. According to mentioned this thesis aims to study the main performance conditions in the resistance of conventional and self-compacting concrete anchors. This research is primarily focused on the evaluation of the influence of several variables on the strength of the anchoring, both in conventional concrete and self-compacting concrete. In order to complete this study it has been required the manufacture of two concrete supports on which to develop the tests. One of the blocks has been manufactured with conventional concrete and the other with self-compacting concrete. A total of 174 steel bar anchors have been made in each one of the concrete pieces varying the studied parameters in order to obtain results for all variables considered. The tests to be performed on both blocks are exactly the same in order to compare the difference between an anchor on a stand with vibrated concrete (HVC) and a self-compacting concrete (SCC). Each type of test required two repetitions in the same piece. The pulling test of the bars was made with a hollow jack and with an instrumentation system for reading and recording data in real time. The use of a powerful statistical tool in the analysis of the results allowed to numerically determine and evaluate the influence of the variables considered in the resistance of the anchors made. It has likewise enabled to differentiate the results obtained in the self-compacting and conventional concretes, from both the outlook of the mechanical strength and the deformations undergone by uprooting. The mechanical strength of an anchor is defined as the strength undergone in a direction of the bar to uproot it from the support. Likewise, the movement is defined as the separation between a fixed point of the bar and a fixed point from the support considering the direction of the bar. These points are only determined once the anchor is finished, with the bar, at the intersection in the flat surface of the support. The conclusions obtained have established which variables affect the execution of the anchors and in what quantity. They have also permitted to determine the difference between the anchors in vibrated concrete and selfcompacting concrete with very interesting results that also allow to assess the influence of these mentioned variables. Three groups are highlighted among the conclusions called high influence, low influence and no influence. In every case is necessary to perform the study in terms of loading and movement. In terms of loading, there are considered as high influence two variables: drilling machinery and anchorage material. In terms of movement, there are considered as high influence the drilling diameter and the cleaning and moisture of the support, besides the drilling machinery and the anchorage material. Variables such as type of concrete, drilling direction and cleaning and moisture of the support are considered of low influence in terms of load. In terms of movement, the type of concrete and the direction of the drilling are considered variables of low influence. Within the no influence section in terms of loading, there are included the diameter of the drilling and the height of the drill. In terms of loading, the height of the drill is considered as a no influence variable. We can affirm that the differences among the loading values increase significantly in terms of movement.
