Socializaci?n de diferentes textos para la producci?n escrita en los estudiantes del grado octavo del Colegio San Paulo de Tocancipa S.A.S

104 p. Recurso Electr?nicoEste proyecto de investigaci?n presenta una propuesta did?ctica dirigida (a manejar la producci?n escrita de los estudiantes) que se desarroll? en el grado octavo de educaci?n secundaria en el Colegio San Paulo Tocancip? S.A.S, el cual se encuentra ubicado en Tocancip? (Cundinamarca). La necesidad de plantear y desarrollar este taller de escritura surge como resultado de las experiencias de las de los estudiantes al producir un texto en las diferentes actividades de sensibilizaci?n que realizamos como (leer un cuento y luego plasmar la idea de lo recuerdan del cuento.). Esto nos permiti? centrarnos en lo referente a la ausencia de h?bitos de escritura que presentan los estudiantes al estar expuestos a actividades rutinarias y repetitivas que vinculan el manejo de la lengua escrita. Teniendo en cuenta las necesidades de los estudiantes de grado octavo se procede a dise?ar y aplicar una propuesta pedag?gica que busque fortalecer el proceso de escritura de los estudiantes, de tal forma que en este ejercicio partamos de sus gustos e intereses, generando procesos de escritura libres y espont?neos mediados por su imaginaci?n, lo cual a su vez nos permiti? producir una amplia gama de textos, sin tener en cuenta la su naturaleza del mismo para ello utilizamos: cuentos, recetas, carta, micro relato, autobiograf?a entre otros. Que, a lo largo del proceso de investigaci?n, se pudo evidenciar que cambios surgen en la estructura de cada uno de los procesos que desarrollar?amos como: el pensamiento, la asociaci?n, el reconocimiento, la categorizaci?n, la segmentaci?n entre otros.This research project presents a didactic proposal directed (a maneuver of the written production of the students) that was developed in the eighth grade of the secondary education in the School San Pablo Tocancip? S.A.S, which is located in Tocancip? (Cundinamarca). The need to raise and develop this higher writing arises as a result of the students' experiences to produce a text in the various sensitization activities that are performed as (read a story and then translate the idea of the memory of the story). This allowed us to focus on the absence of writing habits that introduce students to being exposed to the routine and repetitive activities that link the management of written language. Taking into account the needs of eighth grade students in the process of designing and applying a pedagogical proposal that seeks to strengthen the writing process of students, so that in this exercise partial of their tastes and interests, generating processes of Free writing And spontaneous mediated by his imagination, which in turn allowed us to produce a wide range of texts, without taking into account the nature of the same used for it: stories, recipes, letter, micro story, autobiography among others. Throughout the research process, it was possible to show that changes arise in the structure of each of the processes that are achieved as: thought, association, recognition, categorization, segmentation among others. Keywords: writing, activities, texts, tools, stories, essay writing, grammar rules

Identificación del documento de acuerdo al código del cuadro de clasificación documental: caso Universidad Politécnica Salesiana del Ecuador

Ante la falta de una cultura archivística en una organización, los documentos realizan una tramitación interna sin tener un control o conocer a qué proceso pertenece, de igual manera la terminología se desconoce confundiendo “conservar” como incorporar los documentos en una carpeta, folder, sobre y ubicarlos en algún espacio físico a la espera del personal que trabaja en un Archivo. La Universidad Politécnica Salesiana en su ambiente organizacional apuesta para que el documento desde su creación tenga consignado una identificación de acuerdo al código del cuadro de clasificación documental. El código estará reflejado en todo el proceso administrativo y académico con la compañía de una estructura alfanumérica que permita agruparlos bajo un mismo número de trámite o asunto. El incorporar el código y la estructura alfanumérica permitirá que el personal ordene la documentación de acuerdo a la estructura dada en el Cuadro de Clasificación Documental

Ultrasonic monitoring of early larval development of fish in tanks. Case study: Gilthead seabream (Sparus aurata)

Swimbladder inflation is a significant matter in intensive fish farming, since it is related to larval survival rate and the morphological quality of individuals. In this work, we propose a non-invasive acoustic technique using ultrasound to monitor the swimbladder development of gilthead seabream (Sparus aurata) in tanks. The fundamental hypothesis is that, due to the high acoustic contrast of gas, the swimbladder’s inflation process can be detected by measuring the larvae’s target strength during their early development. Backscatter numerical models using the finite element method, developed from biological measurement data, were applied to evaluate the feasibility of the proposed method. The acoustic measurements were obtained using an EK60 Simrad echosounder working at 200 kHz. The target strength values were evidenced with and without the presence of a developed swimbladder, showing a statistically significant relationship with the swimbladder’s standard length, area and the percentage of larvae with a swimbladder. The experiments were carried out in the Spanish Institute of Oceanography (IEO)’s marine aquaculture plant at Mazarr´on (Murcia, Spain)

Using ultrasound for the monitoring and control of larval development of gilthead seabream (Sparus aurata) in tanks

In this work, we propose a non-invasive acoustic technique using ultrasound for the monitoring and control of larval development of gilthead seabream (Sparus aurata) in tanks. Biological measurements and target strength (TS) measurements have been carried out using a EK60 Simrad echosounder working at 200 kHz. The experiments have been carried out for three consecutive years in the marine aquaculture plant that Spanish Institute of Oceanography (IEO) has at Mazarron (Murcia, Spain). For the interpretation of the results, backscatter models were considered using the finite element method. The target strength values were evidenced with and without the presence of the developed swimbladder, showing a statistically significant relationship with the standard length, the area of the swimbladder and the percentage of larvae with a swimbladder

Modulation of neuronal cell affinity of composites scaffolds based on polyhydroxyalkanoates and bioactive glasses

Biocompatibility and neuron regenerating properties of various bioactive glass (BG)/Polyhydroxyalkanoate (PHA) blend composites were assessed in order to study their suitability for peripheral nerve tissue applications, specifically as lumen structures for nerve guidance conduits (NGCs). BG/PHA blend composites were fabricated using Bioactive glass® 45S5 (BG1) and BG 1393 (BG2) with the 25:35 poly(3-hydroxyoctanoate/poly3-hydroxybutyrate), 25:75 P(3HO)/P(3HB) blend (PHA blend). Various concentrations of each BG (0.5, 1.0 and 2.5 wt%) were used to determine the effect of BG on neuronal growth and differentiation, in single culture using NG108-15 neuronal cells and in a co-culture along with RN22 Schwann cells. NG108-15 cells exhibited good growth and differentiation on all the PHA blend composites showing that both BGs have good biocompatibility at 0.5, 1.0 and 2.5 wt% within the PHA blend. The Young's modulus values displayed by all the PHA blend/BG composites ranged from 385.6 MPa to 1792.6 MPa, which are able to provide the required support and protective effect for regeneration of peripheral nerves. More specifically, the tensile strength obtained in the PHA blend/BG1 (1.0 wt%) (10.0 ± 0.6 MPa) was found to be similar to that of rabbit peroneal nerve. This composite also exhibited the best biological performance in supporting growth and neuronal differentiation among all the substrates. The neurite extension on this composite was found to be remarkable with the neurites forming a complex connection network

<p>Abstract</p> <p>Background</p> <p><it>Leishmania (Viannia) shawi </it>parasite was first characterized in 1989. Recently the protective effects of soluble leishmanial antigen (SLA) from <it>L. (V.) shawi </it>promastigotes were demonstrated using BALB/c mice, the susceptibility model for this parasite. In order to identify protective fractions, SLA was fractionated by reverse phase HPLC and five antigenic fractions were obtained.</p> <p>Methods</p> <p>F1 fraction was purified from L. (V.) shawi parasite extract by reverse phase HPLC. BALB/c mice were immunized once a week for two consecutive weeks by subcutaneous routes in the rump, using 25 μg of F1. After 1 and 16 weeks of last immunization, groups were challenged in the footpad with L. (V.) shawi promastigotes. After 2 months, those same mice were sacrificed and parasite burden, cellular and humoral immune responses were evaluated.</p> <p>Results</p> <p>The F1 fraction induced a high degree of protection associated with an increase in IFN-γ, a decrease in IL-4, increased cell proliferation and activation of CD8⁺T lymphocytes. Long-term protection was acquired in F1-immunized mice, associated with increased CD4⁺central memory T lymphocytes and activation of both CD4⁺and CD8⁺T cells. In addition, F1-immunized groups showed an increase in IgG2a levels.</p> <p>Conclusions</p> <p>The inductor capability of antigens to generate memory lymphocytes that can proliferate and secrete beneficial cytokines upon infection could be an important factor in the development of vaccine candidates against American Tegumentary Leishmaniasis.</p

Consensus on complementary feeding from the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition: COCO 2023

Abstract Complementary feeding (CF) is defined as infant feeding that complements breastfeeding or, alternatively, breastfeeding with a breast milk substitute, and is a process that goes beyond simply providing guidance on what and how to introduce foods. The information provided by health professionals should be up-to-date and evidence-based. There are different guidelines or position papers at the international level, which, although most of the recommendations may be applicable, there are some others that require regionalization or adaptation to the conditions and reality of each area. The Nutrition working group of the Latin American Society of Pediatric Gastroenterology, Hepatology and Nutrition convened a group of experts, representatives from each of the countries that make up the society, with the objective of developing a consensus on CA, incorporating, when possible, local information that adapts to the reality of the region. The purpose of this document is to show the results of this work. Through Delphi methodology, a total of 34 statements or statements regarding relevant aspects of CA were evaluated, discussed and voted upon.Resumen La alimentación complementaria (AC) se define como la alimentación de los lactantes que complementa a la lactancia materna o en su defecto, a la lactancia con un sucedáneo de la leche materna, y es un proceso que va más allá de simplemente una guía sobre qué y cómo introducir los alimentos. La información brindada por parte de los profesionales de la salud debe ser actualizada y basada en evidencia. Existen diferentes guías o documentos de posición a nivel internacional, que, aunque la mayoría de las recomendaciones pueden ser aplicables, hay algunas otras que requieren una regionalización o adecuación a las condiciones y realidad de cada zona. El grupo de trabajo de Nutrición de la Sociedad Latinoamericana de Gastroenterología, Hepatología y Nutrición Pediátrica convocó a un grupo de expertos, representantes de cada uno de los países que conforman la sociedad, con el objetivo de desarrollar un consenso sobre la AC, que incorporó cuando así fue posible, información local que se adapte a la realidad de la región. El objetivo de este documento es mostrar los resultados de dicho trabajo. A través de metodología Delphi, se evaluaron, discutieron y votaron un total de 34 declaraciones o enunciados con respecto a aspectos relevantes de la AC
