Alternative for economic growth in the Chambo canton through the feasibility project of the milk cooling plant

Las acciones agropecuarias son una fuente primordial de la economía ecuatoriana. En el cantón Chambo, perteneciente a la provincia de Chimborazo, ubicado a 17 km de la ciudad de Riobamba; la agricultura, la ganadería, la producción de leche, la elaboración de ladrillos y tejas artesanalmente, son ejes de vital importancia pues generan gran impacto en el desarrollo local y regional. Con 65 familias como socios dinámicos, la Asociación Agropecuaria San Antonio de Guayllabamba, se dedica a la producción y comercialización de leche. La industria ecuatoriana se caracteriza por producir leche cruda, que según el BCE (2016) en el último año obtuvo un 3,5% de incremento en la producción diaria de litros, catalogándose la región sierra como la más relevante de este sector alimenticio. El presente proyecto busca evaluar la factibilidad de una planta de enfriamiento de leche como una alternativa de crecimiento económico en la Asociación San Antonio de Guayllabamba, de manera que los indicadores económicos unitarios permitan resaltar el manejo de una producción sostenible y al mismo tiempo se mantengan las exigencias económicas, sociales, tecnológicas y ambientales por lo que la presente investigación es de carácter explicativa, hipotética deductiva, histórica lógica y analítica sintética en la cual la observación directa y la encuesta fueron las técnicas de recolección de datos. En el proceso de investigativo se consideró lineamientos de Gestión y Desarrollo Empresarial, conjuntamente con la economía social. En la principal búsqueda de trabajo se determinó que la planta de enfriamiento de leche ayudará a incrementar los ingresos económicos de los asociados, generando así un comportamiento positivo de los productores hacia el desarrollo económico que desean alcanzar para mejorar su calidad de vida.      Agricultural activities are a dynamic source of the Ecuadorian economy. In the canton Chambo, belonging to the province of Chimborazo, located 17 km from the city of Riobamba; agriculture, livestock, milk production, brick making and handcrafted tiles, are vital axes because they generate great impact on local and regional development. The San Antonio de Guayllabamba Agricultural Association is an organization that has 65 families as active partners and is dedicated to the production and marketing of milk. Consequently, the Ecuadorian industry is characterized by producing raw milk, which according to the ECB (2016) in the last year obtained a 3.5% increase in the daily production of liters, ranking the Sierra region as the most relevant in this food sector . The present project seeks to evaluate the feasibility of a milk cooling plant as an alternative for economic growth in the San Antonio de Guayllabamba Association, so that the unit economic indicators that allow the management of sustainable production and that at the same time are highlighted present time economic, social, technological and environmental requirements. Research is determined as explanatory, hypothetical-deductive, historical-logical and analytical-synthetic. Among the data collection techniques, direct observation and survey were used. In the investigation process, Management and Business Development guidelines were considered, together with the Social Economy. In the main finding of the work it was determined that the milk cooling plant will help to increase the economic income of the associates, thus generating a positive behavior of the producers towards the economic development that they wish to achieve in order to improve their quality of life

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Search for narrow resonances using the dijet mass spectrum in pp collisions at s√=8 TeV

Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at s√=8  TeV. The data sample corresponds to an integrated luminosity of 4.0  fb−1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall–Sundrum graviton model in the dijet channel

Transverse momentum and pseudorapidity distributions of charged hadrons in pp collisions at (s)\sqrt(s) = 0.9 and 2.36 TeV

Measurements of inclusive charged-hadron transverse-momentum and pseudorapidity distributions are presented for proton-proton collisions at sqrt(s) = 0.9 and 2.36 TeV. The data were collected with the CMS detector during the LHC commissioning in December 2009. For non-single-diffractive interactions, the average charged-hadron transverse momentum is measured to be 0.46 +/- 0.01 (stat.) +/- 0.01 (syst.) GeV/c at 0.9 TeV and 0.50 +/- 0.01 (stat.) +/- 0.01 (syst.) GeV/c at 2.36 TeV, for pseudorapidities between -2.4 and +2.4. At these energies, the measured pseudorapidity densities in the central region, dN(charged)/d(eta) for |eta| < 0.5, are 3.48 +/- 0.02 (stat.) +/- 0.13 (syst.) and 4.47 +/- 0.04 (stat.) +/- 0.16 (syst.), respectively. The results at 0.9 TeV are in agreement with previous measurements and confirm the expectation of near equal hadron production in p-pbar and pp collisions. The results at 2.36 TeV represent the highest-energy measurements at a particle collider to date

Outcomes in Newly Diagnosed Atrial Fibrillation and History of Acute Coronary Syndromes: Insights from GARFIELD-AF

BACKGROUND: Many patients with atrial fibrillation have concomitant coronary artery disease with or without acute coronary syndromes and are in need of additional antithrombotic therapy. There are few data on the long-term clinical outcome of atrial fibrillation patients with a history of acute coronary syndrome. This is a 2-year study of atrial fibrillation patients with or without a history of acute coronary syndromes

Transverse-momentum and pseudorapidity distributions of charged hadrons in pppp collisions at s\sqrt{s} = 7 TeV

Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at $\sqrt{s} = 7$~TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit-pairs, and fully reconstructed charged-particle tracks. The combination of the three methods gives a charged-particle multiplicity per unit of pseudorapidity \dnchdeta|_{|\eta| < 0.5} = 5.78\pm 0.01\stat\pm 0.23\syst for non-single-diffractive events, higher than predicted by commonly used models. The relative increase in charged-particle multiplicity from $\sqrt{s} = 0.9$ to 7~TeV is 66.1\%\pm 1.0\%\stat\pm 4.2\%\syst. The mean transverse momentum is measured to be 0.545\pm 0.005\stat\pm 0.015\syst\GeVc. The results are compared with similar measurements at lower energies.Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at sqrt(s) = 7 TeV are measured with the inner tracking system of the CMS detector at the LHC.
