This paper describes an alternative methodology to determine the thermal effusivity of a liquid sample using the recently proposed electropyroelectric technique, without fitting the experimental data with a theoretical model and without having to know the pyroelectric sensor related parameters, as in most previous reported approaches. The method is not absolute, because a reference liquid with known thermal properties is needed. Experiments have been performed that demonstrate the high reliability and accuracy of the method with measurement uncertainties smaller than 3%. © 2015 AIP Publishing LLC.

Recent research efforts in biomedical science areas report the use of Optimal Control techniques in the development of effective therapeutic treatments. However, the solution algorithms of this kind are complex and often not generally applicable. In this work we analyze a model of the natural response of immune system to the determination of a treatment based on the application of therapeutic agents and a Dynamic Programming Theory. Objective function was proposed for minimizing harm to an organism by a pathogen attack and excessive use of drugs. The problem was formulated using the Bellman principle of optimality and solved by using an exhaustive search method: the Iterative Dynamic Programming Algorithm. This class of tools has been scarcely explored in medicine and biomedical research; the results demonstrate reliability of this tool in the determination of best medical treatment. © 2013 Elsevier B.V.

We analyzed the effect of temperature, rainfall, rainfed harvested area and labor applied on honey production in the second honey harvest season (1998-2010), in Aguascalientes. This analysis was performed by modeling a Cobb-Douglas function by twostage least squares. The criteria for variables selection was based on works concerning the phenology of bees, and the predominant source of nectar, as well as, the design of the production function. We obtained a model based on each apiary (78 apiaries) annual data, considering 4,901 beehives, with a R2in differences of 0.71. The honey per beehive production elasticity, in relation to rainfall, rainfed harvested area and labor were positive, and negative regarding last year honey production, and temperature. The weather and labor per beehive were the factors responsible for yield variability of honey per beehive. © 2014, Universidad Autonoma Chapingo. All rights reserved.
