Addition of dianions of carboxylic acids to imines. Influence of the acid in the outcome of the reaction

The addition of different carboxylic acids dianions to N-benzylidenebenzeneamine have been studied. The outcome of the reaction depends on the acid. Saturated ones lead to β-aminoacids with good yields and syn-selectivity whereas α,β-unsaturated ones lead to α− and γ− regioisomers with a regioselectivity that depends on the steric hindrance around the reactive centre. From some of these unsaturated acids, polyunsaturated carboxylic acids can be obtained as a change in the reaction conditions lead to the in situ elimination of aniline. From o-methyl aromatic acids δ-aminoacids are isolated with uneven results. Those derived from six member arene carboxylic acids give, on standing, dihydro-2-pyridones as the sole product.Gil Grau, Salvador, [email protected], Parra Alvarez, Margarita, [email protected], Rodriguez Abad, Pablo, [email protected]

BODIPY Core as Signaling Unit in Chemosensor Design

BODIPY derivatives possess unique photophysical properties and for these reasons, they have been used in numerous fields. Among the different applications, they are used in designing chemosensors that has increased in the last years. Here, we report several strategies and examples for detecting analytes of different characteristics: cations, anions, and hazardous and pollutant neutral molecules using BODIPY core as signaling unit

Red or Blue? Gold Nanoparticles in Colorimetric Sensing

Gold nanoparticles (AuNPs) have been extensively used for the design of colorimetric sensors and probes due to their interesting photophysical properties. In particular, their surface plasmon resonance (SPR) is influenced not only by the size but also by the shape or the properties of the matrix surrounding the nanoparticles. This SPR band is sensitive to the proximity of other nanoparticles, and thus, analyte-triggered aggregation of AuNPs results in an important bathochromic shift of the SPR band and a change in the color of the solution from red to blue due to interparticle surface plasmon coupling. The selectivity of the AuNPs-based sensors toward the different analytes will depend on the recognition properties of the molecules attached to the surface of the nanoparticles. In this chapter, a selection of biologically active molecules has been considered as analytes: neurotransmitters, nerve agents, pesticides, and carboxylates of biological interest

Melhoria da Atenção à Saúde das Crianças Entre Zero e 72 Meses da Unidade Básica de Saúde Ivaneide Cordeiro, Ipixuna, AM

Cada país tem o dever de proporcionar que as crianças cresçam saudáveis e com uma boa educação, portanto, a saúde da criança é uma ação programática de suma importância e preconizada pelo Ministério da Saúde, sendo denominada de puericultura. O objetivo deste trabalho foi melhorar a atenção ao Programa de Puericultura, na Unidade de Ivaneide Cordeiro, no Município de Ipixuna, Amazonas. O trabalho foi realizado em um período de 16 semanas com crianças de zero a 72 meses de idade, nos meses a partir de junho, julho, agosto e setembro em que foram desenvolvidas ações com base em quatro eixos norteadores do projeto político-pedagógico do curso (1) Organização e gestão do serviço, (2) Monitoramento e avaliação, (3) Engajamento público e, (4) Qualificação da prática clínica. Buscou-se organizar o serviço através de capacitação da equipe através do protocolo de puericultura disponibilizado pelo Ministério da Saúde, houve ampla divulgação a comunidade e busca de parcerias com os gestores locais para atingir uma cobertura total de crianças. Foram designados dois dias na semana para a realização desta ação e utilizamos as cadernetas da criança e as fichas espelhos disponibilizadas pelo curso. Ao final dos 4 meses, 100% (52) das crianças cadastradas foram acompanhadas, destas, a vacinação, avaliação de risco, busca ativa de crianças faltosas ocorreu para 100% das crianças, na primeira consulta odontológica não atingimos o 100% das crianças pela falta de suficientes profissionais de odontologia na UBS. Podemos concluir que os resultados foram muito satisfatórios pois houve uma organização do serviço, atingimos cobertura total de crianças acompanhadas, e serviu para chamarmos a atenção aos gestores sobre algumas deficiências que mesmo dando fim a intervenção persistem como a garantia do teste do pezinho e avaliação auditiva

Creacion de una marca gráfica y elaboración del manual de identidad visual corporativa para el grupo empresarial grupo autos de la ciudad de Cali

La idea entral de este proyecto surge por la necesidad de diseñar la marca gráfica de Grupo Autos, grupo empresarial en gestación. El sector automotriz en el país es uno de los más importantes y cuenta con plantas de ensambladoras y una gran cantidad de concesionarios de diversas marcas desde gamas económicas hasta las más costosas. En el proyecto se aborda la teoría básica de la marca y del “branding”, este último mencionado como una herramienta muy útil de posicionamiento de la marca. Una vez concluida la investigación y conceptualización de los datos obtenidos se realiza la fase de producción y creación de la imagen gráficaProyecto de grado (Diseñador de la Comunicación Gráfica)-- Universidad Autónoma de Occidente, 2012PregradoDiseñador(a) de la Comunicación Gráfic

New approach to condensed pyrid-2-ones

We wish to report a simple procedure for the preparation of 5-substituted-thienopyridin-7-ones and 7-substituted-1,6-naphthyridin-5(6H)-ones, in good yields, from the dianions of 3-methylthiophene-2-carboxylic and 2-methylnicotinic acids on treatment with nitriles.Brun Sanchez, Eva Maria, [email protected] ; Gil Grau, Salvador, [email protected] ; Parra Alvarez, Margarita, [email protected]

Effect of deficit irrigation and reclaimed water on yield and quality of grapefruits at harvest and postharvest

The aim of our research was to discover the effects of the long-term irrigation with saline reclaimed (RW) and transfer (TW) water and different irrigation strategies: control (C) and regulated deficit irrigation (RDI) on yield and fruit quality of grapefruit at harvest and during cold storage. T W-RDI treatment decreased tree canopy (TC) and crop load, resulting in a 21% reduction of fruit yield. Regarding fruit quality, RW notably decreased peel thickness at harvest (about 8%); however, this difference was not remained during cold storage. Sugar/acid ratio was mainly increased by RDI, but also by RW, due to an important increase in soluble solid content (11% of average value for TW-RDI, RW-C and RW-RDI). In addition, RDI combined with RW, significantly increased the number of fruits in small category 5 at the end of cold storage. Finally, neither ratio yield/TC nor irrigation water productivity were affected by any irrigation treatments.This study was supported by two CICYT projects (AGL2010-17553 and AGL2013-49047-C2- 515 2-R) projects and SENECA-Excelencia Científica (19903/GERM/15)

Innovación educativa a través de estrategias de enseñanza mediadas por las TIC en la formación inicial de profesores de inglés

This paper describes the results of the first cycle of a co-joint research study in methodological innovation in the initial education of pre-service language teachers. The experience consisted of the implementation of several learning strategies mediated by different ICT tools. These strategies were used by three teachers, in three different academic spaces of a B.A. in Spanish and Foreign Languages during the second semester of 2018. The purpose of this implementation was to examine the value of ICT-mediated learning strategies and gaining insights into how to integrate ICTs with a process of pedagogical and methodological innovation. The results of the data analysis, which were collected through a qualitative-quantitative survey, indicate that the integration of strategies mediated by ICTs seems to be essential for methodological and pedagogical innovation because they promote the development of collaborative and cooperative learning, foster autonomy and self-directed learning. Besides, these strategies also provide a range of possibilities for bolstering the development of the capacity of agency pre-service teachers.Este documento describe los resultados de una experiencia de investigación de acción conjunta en la implementación de estrategias de enseñanza mediadas por las TIC.
