“…Environmental conditions, which include temperature, water accessibility and light exposure, are known to modulate the phenolic profile of different fruits [44]. In this sense, SO, originally from the region of Mendoza (Argentina), were exposed to a temperate-arid climate and abundant solar exposure [45]. On the other hand, NO, originally from the region of Valencia (Spain), were exposed to a Mediterranean climate, characterized by mild and wet winters and hot and dry summers [46].…”

Optimization of a polyphenol extraction method for sweet orange pulp (Citrus sinensis L.) to identify phenolic compounds consumed from sweet oranges

et al. 2019

The consumption of sweet oranges has been linked to several health benefits, many of which are attributed to hesperidin, a flavanone that is present in high amounts in these fruits. However, other phenolic compounds can contribute to the bioactivity of sweet orange. To link those effects to their phenolic profile, the complete characterization of the phenolic profile is mandatory. Although many studies have profiled the phenolic composition of orange juices, their pulps, which retain phenolic compounds, are overlooked. This fact is particularly relevant because dietary guidelines recommend the consumption of whole fruits. Therefore, this study aimed to develop a specific method for the optimal extraction of phenolics from orange pulp and to use this method to characterize these fruits grown at different locations by HPLC-ESI-MS/MS. The extraction conditions that reported the highest total polyphenol content (TPC) and hesperidin contents were 20 mL/g, 55 °C, and 90% methanol. The extraction time and number of sequential steps were further evaluated and optimized as 20 min and two extraction steps, respectively. Although lower extraction rates were achieved when using ethanol as the extraction solvent, high TPC and hesperidin yields were obtained, suggesting the potential use of this methodology to produce phenolic-rich extracts for the food industry. By applying the optimized methodology and analyzing the extracts by HPLC-ESI-MS/MS, geographic cultivation regions were demonstrated to affect the phenolic profiles of oranges. In short, we developed a quick, easy-to-perform methodology that can be used to extract orange phenolics from pulp for their identification and quantification and to evaluate the factors that affect the phenolic profile in sweet orange pulps.

“…A escala local, para el AMM se han realizado estudios sobre las variables urbano-edilicias relacionadas con el comportamiento energético, basados en conjuntos reales representativos Arboit et al, 2010) y se ha avanzado desde años recientes en modelos a escala urbana (Mutani et al, 2018). Se cuenta con resultados de las variables urbanas: forma de las manzanas urbanas, orientación de las manzanas, índices de vegetación de las manzanas urbanas y de las variables edilicias: huella edilicia y factor edilicio total.…”

Determinación de variables edilicias presentes en morfologías del Área Metropolitana de Mendoza para la eficiencia energética

2022

La morfología urbano-edilicia es una determinante en el consumo de energía y es relevante en regiones áridas templadas con generoso recurso solar. Las ciudades insertas en zonas áridas afrontan una serie de riesgos que amenazan su sostenibilidad, impactadas por los efectos del cambio climático y la urbanización, con consecuencias sobre la inequidad de consumos. El objetivo del trabajo es evaluar en el Área Metropolitana de Mendoza (AMM) las características de las variables: altura edilicia, separación edilicia, relación altura/separación edilicia y densidad edilicia. Se trabajó con sistemas de información geográfica (SIG) y se realizó el análisis estadístico de los resultados, a fin de implementar a futuro un modelo para determinar estrategias dirigidas a maximizar la eficiencia y generación energética del sector edilicio urbano con un aprovechamiento máximo de los recursos disponibles. Las manzanas analizadas poseen valores medios-bajos de separación edilicia y valores bajos de: altura edilicia, relación altura/separación edilicia y densidad edilicia. El 49,10 % de manzanas posee una separación edilicia media de 16,61 m, el 73,90 % tiene una altura media <3,5 m, el 90,52 % cuenta con valores medios <0,30 de variable relación altura/separación edilicia de manzanas urbanas y el 80,85 % presenta valores medios de densidad edilicia <2m2/m3. Con base en los resultados obtenidos, se concluye que el AMM posee un modelo de ciudad difusa adaptado al clima semidesértico. Se cree factible revalorizar, preservar y regenerar el modelo actual de “ciudad oasis” en zonas ya consolidadas y plantear un nuevo modelo urbano a futuro que considere los diferentes contextos culturales, el patrimonio urbano-edilicio y paisajístico, las diferentes oportunidades y las limitaciones para el progreso hacia la sostenibilidad energético-ambiental.

“…In this way, a probable energy yield can be effectively calculated based on the reliability of the data obtained and the correct evaluation of the parameters used in the simulations. Zhang et al reviewed the state-of-the-art technologies for evaluating the reliability of large-scale PV systems [27]; on the other hand, Arboit et al assessed the solar potential of low-density urban environments [28,29]. Salazar and Raichijk studied the assessment of cloud conditions for determining the characteristics of solar resource availability and proposed a way to predict the actual cloud status in high altitude sites [30].…”

“…Unfortunately, due to the cost of solar stations, the limited availability of skilled human resources, and low research budgets, it is impossible to install a sufficient number of measuring devices for the large areas under study [45][46][47]. Thus, important information related to the effect of local factors such as landforms, cloudiness, or presence of aerosols is not considered [28][29][30]40].…”

The use of renewable energies requires a precise and detailed quantification of the resource available. Because of the cost of solar stations or limited availability of skilled human resources, in most emerging countries, this assessment is made only on a few points scattered over large areas. We report here a simple and inexpensive method to evaluate the photovoltaic (PV) potential for a specific geographic region and a given PV capture technology. The system allows for a direct evaluation of the energy actually obtainable by scaling the measurement array of photovoltaic cells. The proposed measurement system can be installed as a stand-alone unit, or as part of a measurement network, connected to a more sophisticated central hub. The measurement station consists of said PV array (or similar PV array), a resistor, and a portable data logger. The system is calibrated with a device composed of a small array of PV cells, a resistor load bank, and two multimeters. Due to its low cost, this system can be replicated as many times as required with minimal investment. This would make it possible to evaluate the available photovoltaic potential of large regions with accurate and detailed data. Measurements carried out in Buenos Aires and in Antarctica confirm the consistency of the method.
