Effects of saline reclaimed waters and deficit irrigation on Citrus physiology assessed by UAV remote sensing

The aim of our research was to discover the effects of the long-term irrigation with saline reclaimed (RW) and transfer (TW) water and different irrigation strategies: control (C) and regulated deficit irrigation (RDI) on yield and fruit quality of grapefruit at harvest and during cold storage. TW-RDI treatment decreased tree canopy (TC) and crop load, resulting in a 21% reduction of fruit yield. Regarding fruit quality, RW notably decreased peel thickness at harvest (about 8%); however, this difference was not remained during cold storage. Sugar/acid ratio was mainly increased by RDI, but also by RW, due to an important increase in soluble solid content (11% of average value for TW-RDI, RW-C and RW-RDI). In addition, RDI combined with RW, significantly increased the number of fruits in small category 5 at the end of cold storage. Finally, neither ratio yield/TC nor irrigation water productivity were affected by any irrigation treatments.This study was supported by two CICYT (AGL2010-17553 and AGL2013-49047-C2-482 515 2-R) projects and SIRRIMED (KBBE-2009-1- 2-03, PROPOSAL N◦245159) 483 project.

CO2 capture and conversion: A homemade experimental approach

During the SARS-2-Covid pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students’ homes. Thanks to this approach students were able to perform ~25 experiments during each one of the Fall 2020 and Spring 2021 semesters in an elective Electrochemistry and Corrosion course offered to Chemical Engineering undergraduates. In addition to performing traditional experiments, students were encouraged to design some of their own and have the entire group reproduce them. One of such student-designed experiments involved the capture of CO2 and its reduction with a readily available active metal (i.e., Al foil) in aqueous media to generate potentially useful products. The highly negative standard potential of Al is exploited for the reduction of lab-generated CO2, and the products are chemically tested. Al as a foil has been reported to be electrochemically inactive for carbon dioxide reduction. However, encouraged by an earlier report of the reduction of CO2 to CO, the Al surface is activated in the present experiment by removal of its natural oxide layer with a solution of CuCl 2 produced in an electrochemical cell. This procedure enables Al to react with CO2 and yield useful chemistry. This experiment turned to be a discovery trip. The detailed procedure is discussed here, as well as the teaching methodology, grading scheme, and student outcomesPeer Reviewe

Polyphenols and IUGR Pregnancies: Intrauterine Growth Restriction and Hydroxytyrosol Affect the Development and Neurotransmitter Profile of the Hippocampus in a Pig Model

Intrauterine growth restriction (IUGR) refers to poor growth of a fetus during pregnancy due to deficient maternal nutrition or oxygen supply. Supplementation of a mother's diet with antioxidants, such as hydroxytyrosol (HTX), has been proposed to ameliorate the adverse phenotypes of IUGR. In the present study, sows were treated daily with or without 1.5 mg of HTX per kilogram of feed from day 35 of pregnancy (at 30% of the total gestational period), and fetuses were sampled at day 100 of gestation. Fetuses were classified as normal body weight (NBW) or low body weight (LBW) as a consequence of IUGR, constituting four groups: NBW-Control, NBW-HTX, LBW-Control, and LBW-HTX. The brain was removed, and the hippocampus, amygdala, and prefrontal cortex were rapidly dissected. Neuronal markers were studied by immunohistochemistry, and a decrease in the number of mature neurons in the hippocampal Cornu Ammonis subfield 1 (CA1) and the Dentate Gyrus (DG) regions was observed in LBW fetuses together with a higher number of immature neurons and other alterations in neuronal morphology. Furthermore, IUGR conditions altered the neurotransmitter (NT) profile, since an increase in the serotonin (5-HT) pathway was observed in LBW fetuses. Supplementation with HTX was able to reverse the morphological and neurochemical changes, leading both characteristics to values similar to those of NBW fetuses

Methodological improvements in the final project of Civil Engineering Degree

The final project of an engineering degree represents a test of maturity where students must crossexamine all the contents studied in the degree which adds technical difficulties. Traditionally the students are supervised by only one teacher and they usually also take a previous course in the writing of the project. Currently, the program of the Civil Engineering Degree contemplates this activity in the last semester with an allocation of 18 credits. The hardest difficulty noted by students and teachers is the short time estimated for writing it. A teaching innovation project is presented herein which aims to define a working protocol in order to help the student in a more efficient and close way during the development of the task. Among the methodological changes introduced, it should be highlighted the tutoring by professors from different areas of knowledge instead of only one professor as it was traditionally done. Thus, coordination mechanisms must be implemented to guarantee the achievement of the proposed objectives. The innovation project also helps to identify tasks that can be advanced in time and gain time for the effective drafting of the project. Some other solutions found will be presented as well as a comparison of the results obtained along this year with those of the former methodology

Agency Theory (AT): Theoretical Assumptions Applicable to University Management

En Iberoamérica han surgido inquietudes con respecto a la efectividad de las universidades, particularmente respecto de su calidad. Se tiene como premisa indiscutida que la gestión del gobierno universitario es uno de los factores determinantes para mejorar el quehacer administrativo y, desde ahí, las tareas académicas. El propósito de este trabajo es realizar un análisis desde la teoría de agencia (TA ) como una aproximación que puede ayudar a detectar y corregir problemas de gestión del gobierno universitario, entendiendo que se trata de una deriva teórica y no doctrinaria. Para lograr este propósito, se procedió a revisar más de un centenar de textos y artículos publicados en revistas académicas de prestigio internacional. Como hallazgos relevantes, se pueden destacar la identificación y la reflexión en torno a elementos y factores determinantes considerados por la TA , que son aplicables al mundo de la gestión universitaria (GU).: New concerns have been raised in Iberoamerica regarding the effectiveness of universities, especially in terms of their quality. It is an undisputed premise that the management of university governance is one of the determining factors to improve administrative tasks and, from there, academic duties. The purpose of this work is to make an analysis based on the Agency Theory (AT) as an estimate that may help detect and correct management problems in university governance, understanding that it is a theoretical drift and not a doctrinal one. In order to achieve this purpose, more than a hundred texts and papers published in internationally recognized academic journals were reviewed. As relevant findings, it is possible to highlight the identification and reflection about determining elements and factors considered by the AT, which are applicable to the world of university management (GU, by its Spanish acronym

Aplicación de las técnicas mnemotécnicas con realidad aumentada (ra) del magnicidio del líder político Luis Carlos Galán Sarmiento en el parque principal del municipio de Soacha.

Uno de los desafíos para la educación en una Colombia del post-conflicto tiene que ver con la relación entre tecnologías y memoria histórica. El parque principal del municipio de Soacha puede ser un pretexto para lograr dicha relación. Este lugar ha sido clave en el desarrollo de acontecimientos que cambiaron la historia, la sociedad, la política y la economía del país. Por ejemplo, el suceso del 18 de agosto de 1989, el asesinato del líder político candidato a la presidencia de la república de Colombia: Luis Carlos Galán Sarmiento. Los avances tecnológicos pueden representar un apoyo en la compresión y el rescate de la memoria de estos acontecimientos

Polyphenols and IUGR Pregnancies : effects of the Antioxidant Hydroxytyrosol on Brain Neurochemistry and Development in a Porcine Model

Supplementation of a mother's diet with antioxidants, such as hydroxytyrosol (HTX), has been proposed to ameliorate the adverse phenotypes of fetuses at risk of intrauterine growth restriction. In the present study, sows were treated daily with or without 1.5 mg of HTX per kilogram of feed from day 35 of pregnancy (at 30% of total gestational period), and individuals were sampled at three different ages: 100-day-old fetuses and 1-month- and 6-month-old piglets. After euthanasia, the brain was removed and the hippocampus, amygdala, and prefrontal cortex were dissected. The profile of the catecholaminergic and serotoninergic neurotransmitters (NTs) was characterized and an immunohistochemical study of the hippocampus was performed. The results indicated that maternal supplementation with HTX during pregnancy affected the NT profile in a brain-area-dependant mode and it modified the process of neuron differentiation in the hippocampal CA1 and GD areas, indicating that cell differentiation occurred more rapidly in the HTX group. These effects were specific to the fetal period, concomitantly with HTX maternal supplementation, since no major differences remained between the control and treated groups in 1-month- and 6-month-old pigs
