Bistua : Revista de la Facultad de Ciencias Básicas , 2011,
Abstract: La deficiencia de hierro es la carencia nutricional más frecuente. El objetivo del trabajo fue obtener y evaluar química y microbiológicamente un chocolate de consumo directo adicionado con hierro hemo, procedente de hemoglobina bovina desecada HBD. Teniendo en cuenta el contenido de hierro hemo encontrado en la HBD, a partir de una formulación de chocolate de consumo directo comercializado por Alnut Ltda; se elaboraron a escala de laboratorio, tres lotes de chocolate a adidos con HBD, con un contenido de hierro hemo, por porción de 25 g, equivalente al 10, 12 y 14% del valor diario de referencia de consumo de hierro. Para seleccionar el porcentaje apropiado de HBD a a adir se analizaron sensorialmente, utilizando una prueba de satisfacción global aplicada a 36 ni os en edad escolar, estudiada mediante análisis de varianza de un factor. En planta piloto se definió el tiempo óptimo de mezclado de la HBD, se elaboraron 25 kg de chocolate adicionado y se almacenaron durante 15 días a temperatura ambiente (25 ± 3 °C). Se compararon química y microbiológicamente con el chocolate sin adición utilizando prueba t. Los resultados demostraron que es posible a adir 5,7% de HBD con un tiempo de mezclado de 20 minutos, al chocolate comercializado por la empresa, para obtener un alimento con un contenido de hierro hemo de 2.2 mg/porción, microbiológicamente apto para consumo humano; constituyéndose en una alternativa alimenticia que puede contribuir a incrementar la ingesta de hierro hemo en población en edad escolar.

Abstract: The frequent occurrence of exceptionally very heavy rainfall in Mexico during the summer causes flash floods in many areas and major economic losses. As a consequence, a significant part of the annual government budget is diverted to the reconstruction of the disasters caused by floods every year, resulting hold up in the country development. A key element to mitigate the flash flood hazards is the implementation of an early warning system with the ability to process the necessary information in the shortest possible time, in order to increase structural and non-structural resilience in flood prone regions. The real-time estimation of rainfall is essential for the implementation of such systems and the use of remote sensing instruments that feed the operational rainfall-runoff hydrological models is becoming of increasing importance worldwide. However, in some countries such as Mexico, the application of such technology for operational purposes is still in its infancy. Here the implementation of an operational hydrological model is described for the Mixcoac river basin as part of the non-structural measures that can be applied for intense precipitation events. The main goal is to examine the feasibility of the use of remote sensing instruments and establish a methodology to predict the runoff in real time in urban river basins with complex topography, to increase the resilience of the areas affected by annual floods. The study takes data from weather radar operated by the National Meteorological Service of Mexico, as input to a distributed hydrological model. The distributed unit hydrograph model methodology is used in order to assess its feasibility in urban experimental basin. The basic concepts underlying the model, as well as calibration and validation are discussed. The results demonstrate the feasibility of using weather radar data for modeling rainfall-runoff process with distributed parameter models for urban watersheds. A product resulting from this study was the development of software Runoff Forecast Model (ASM), for application in distributed hydrological models with rainfall data in real time in watersheds with complex terrain, which are usually found in Mexico.

Abstract:

The aim of this study was to describe the compositional, functional and sensory properties of six traditional Mexican cheeses: Panela, Oaxaca, Manchego, Manchego Botanero, Tenate, and Morral. A total of 50 cheeses were analysed. Relevant compositional parameters including pH, aw, proximate composition, NaCl, sugars, lactic and acetic acids, mineral contents, free-amino acid nitrogen, fat acid degree value and total fatty acids were determined. In addition, colour and texture profile analyses of unmelted cheeses and their meltability were investigated. Furthermore, other 30 cheeses were used for a descriptive sensory analysis. Properties of cheeses were described, compared between each cheese, and related to their respective making processes.

Agronomía Costarricense , 2012,
Abstract: plant growth analysis of 5 hybrids of carrot (daucus carota l.) was conducted in cipreses, oreamuno, cartago, with the aim to describe the phenology and growth of carrot. growth analysis was performed using the methodology of functional analysis. the leaf area and the dry weight of each organ and total plant were evaluated, non-linear regression models were adjusted for these variables, the parameters that define the mathematical functions that best describe the growth were obtained and each model was plotted for each variable evaluated. the roots and total dry weight variables were adjusted to an asymptotic nonlinear logistic function: ps=alpha/(1+exp (-beta (x-gamma))); the leaves dry weight and the leaf area were adjusted into the belltype function: ps=alpha*exp (-beta (x-gamma)2). plants showed a sigmoidal growth curve with well-defined stages: a slow growth phase, then an exponential growth segment, followed by a period of reduced growth and finally a stage of stability. the plant spends its early stages of development establishing the photosynthetic machinery, indirect competition with radical development. the root begins to thicken between 63-77 dap, during the second phase of growth, with a greater proportion of assimilates allocated to the root, leading to an increase in its diameter. finally, from the analysis of the variables of total dry weight and leaf area, 2 groups can be established: on the one side supreme, esperanza and bangor, and on the other clx-3193 andsirkana. the first group showed the highest values for such variables.
