Estudio de aprovechamiento energético en las viviendas mediante energÃa solar
Publicado em CD-ROMEn la construcción de nuevos edificios surge la idea de una construcción energéticamente eficiente. El objetivo es
optimizar los recursos energéticos en nuestros hogares y para ello planteamos dos instalaciones a realizar: energÃa
solar térmica (para producción de agua caliente sanitaria) y energÃa solar fotovoltaica (para generación de corriente
eléctrica).
En este artÃculo se trata de calcular el dimensionamiento de ambas instalaciones en función de la ubicación y las
caracterÃsticas de la vivienda. Este estudio plantea los modelos matemáticos de ambas instalaciones y con la ayuda
de la optimización matemática resolvemos los algoritmos sujetos a unas restricciones. Como aplicación del problema
vamos a analizar el caso de una vivienda unifamiliar en una zona climática definida, para asà notar la importancia de
los parámetros que intervienen en la caracterización de las instalaciones.
El objetivo del estudio es determinar de forma rápida y aproximada la viabilidad técnica de ambas instalaciones
conociendo escasos datos de partida
The chemistry and bioactive properties behind microalgae-enriched gluten-free breads
This work aims to: (i) assess volatiles composition of microalgae-enriched gluten-free breads (prepared
with Tetraselmis chuii, Chlorella vulgaris and Microchloropsis gaditana); (ii) report the bioaccessibility of
protein and minerals after a static in vitro digestion model; (iii) understand how it affects the bioactive
properties of gluten-free breads in regard to antioxidant capacity and the α-amylase inhibitory potential.
Therefore, nutritional composition and bioactive properties of gluten-free breads before and after in vitro
digestion model were examined. Identification of compounds responsible for the overall aroma of microalgae
using GC–MS was done. There was a considerable decrease in protein and minerals available after in
vitro digestion, as well as in the antioxidant potential. The overall aroma of microalgae-enriched breads
was mainly due to the presence of alcohols, representing the major class of volatiles present in breads
(3% to 59%), being lower for T. chuii-enriched bread. Terpenes also existed in considerable amounts
especially in M. gaditana (24%) where γ-terpinene was the most abundant. Alkanoic acids were the most
abundant lipophilic bioactive compounds (25%–68%), and 9,12-octadecadienoic acid was the major identified
compound (13%–51%). Phytic acid is also present in all microalgae-enriched breads and may contribute
to the decrease in the bioaccessibility of nutrients.info:eu-repo/semantics/publishedVersio
Protest attitudes and stated preferences: Evidence on scale usage heterogeneity
We contribute to the stated preference literature by addressing scale usage
heterogeneity regarding how individuals answer attitudinal questions capturing
lack of trust in institutions and fairness issues. Using a latent class model, we
conduct a contingent valuation study to elicit the willingness-to-pay to preserve
a recreational site. We find evidence that respondents within the same class, that
is, with similar preferences and attitudes, interpret the Likert scale differently
when answering the attitudinal questions. We identify different patterns of
scale usage heterogeneity within and across classes and associate them with
individual characteristics. Our approach contributes to better a understanding
of individual behavior in the presence of protest attitudes
Identifying Nonrational Behavior in Recreation Demand Models
In the context of an estimated RPL (Random Parameters Logit) choice model of recreational demand for the game reserves of the KwaZulu-Natal province in South Africa, a test on the existence of an underlying rational preference structure is presented. The proposed procedure allows to identify nonrational behavior in the sample. Using two different data sets extracted from the original data base, we show that by improving the data, apparent nonrationality can be eliminated and welfare analysis may be safely conducted.N/
Morphometric differences in the grasshopper Cornops aquaticum (Bruner, 1906) from South America and South Africa
The semi-aquatic grasshopper Cornops aquaticum is native to South America and inhabits lowlands from southern Mexico to Central Argentina and Uruguay. It is host-specific to aquatic plants in the genera Eichhornia and Pontederia. A quarantine population has existed in South Africa for 10 y, and it is planned to release it there as a biological control agent of water hyacinth, E. crassipes. Various studies of C. aquaticum are coordinated under HICWA (www.mpil-ploen.mpg.de). This paper compares the morphometry of the release population and 11 native populations in South America. We tested four hypotheses: 1) South African and South American populations of C. aquaticum differ in morphology; 2) the South African laboratory population is more similar to other isolated populations in South America than to nonisolated populations; 3) morphology differs across sites; 4) morphology differs with host plant. South African populations differed from continental nonisolated populations, but not from continental isolated ones. Isolated populations presented smaller individuals than nonisolated, but there was also a change in male morphology: while in nonisolated populations male wing length was similar to their body length, in isolated populations, male wings were smaller than body length. Females were larger when on Eicchornia azurea than on E. crassipes, while males presented larger wings than their body on E. azurea, and similar lengths on E. crassipes. These morphological changes may have resulted from phenotypic plasticity, selection for small size, or because of a loss of genetic diversity in quantitative traits.Fil: Adis, Joachim.
