Pomace from the wine industry as an additive in the production of traditional sustainable lightweight eco-bricks

This study has been funded by Junta de Andalucía Research Group RNM179 and by Research Projects PPJIB2022-17 and B-RNM-188- UGR20 of the Regional Ministry of University, Research and Innovation of the Junta de Andalucía and FEDER, a way of making Europe. We are grateful to Nigel Walkington for his assistance in revising the English text of the manuscript and to three anonymous reviewers for their helpful suggestions. We also thank Bodegas Navarro (www.bodegasn avarro.es), who supplied the wine pomace, and Ceramica Castillo Siles (www.ceramicacastillosiles.es), who provided the raw materials from Viznar and Guadix. We are also grateful to Junta de Andalucía Research Group HUM629.This research examines fired clay bricks made with waste pomace from the wine industry as an additive in brick production. To this end, we analyse and discuss the chemical, mineralogical, textural and physical-mechanical behaviour of fired bricks made with three concentrations of wine pomace (2.5, 5 and 10 wt%) and at three different firing temperatures (800, 950 and 1100 degrees C) and evaluate their durability to salt crystallization. Variations in colour were also examined. The firing process resulted in the decomposition of phyllosilicates and carbonates, the crystallization of Fe oxides and the appearance of high-temperature Ca- (and Mg-) silicates phases such as gehlenite, wollastonite, anorthite and diopside. The bricks made with added wine pomace had very similar mineralogy to the control samples made without it. The bricks made with added wine pomace were lighter than the control samples and underwent less linear shrinkage during the drying process. Particles in the wine pomace were consumed during firing, leading to the appearance of voids. The bricks made with this additive had higher levels of water absorption and poorer mechanical strength. The greatest colour differences were detected after increasing the amount of waste, which generally resulted in yellower bricks. The increase in firing temperature resulted in an improvement in mechanical resistance regardless of the composition of the bricks. However, bricks fired at 1100 degrees C made without additive are more resistant to damage caused by salts than those made with wine pomace.Junta de Andalucia RNM179Regional Ministry of University, Research and Innovation of the Junta de Andalucia PPJIB2022-17, B-RNM-188- UGR20European Union (EU) Spanish GovernmentFEDERJunta de Andalucía Research Group HUM62

Microbial activity in soil and sediments of the upper arzobispo river basin

Soil biochemical properties are indicators of its quality, properties related to biological cycles of the elements. The enzymatic activities play a key role in the biochemical functioning of soils, including the formation and degradation of organic matter, nutrient cycling and decomposition of xenobiotics. To understand the activity of microbial communities and their effect on the dynamics of organic soil matter, it is necessary to focus on two aspects of the dynamics of the biota and the matrix. This study consisted of an approach to identify the measures that cover the state of health and quality of soils and sediments: the enzymatic activities: acid phosphates, alkaline phosphates, dehydrogenate and biphenyl oxides-ο. It can be seen that the response of the evaluated activities and their possible relationship to the gradient of pollution in the river upstream of Arzobispo indicate a threat of degradation

Effects of Two Intake Levels of \u3cem\u3eLeucaena leucocephala\u3c/em\u3e on Rumen Function of Sheep

Ruminant production systems based on grass pastures often produce poor animal performance as expressed by growth or reproductive rates. The nutrient imbalance affecting rumen function is due to their low energy and protein intake. The incorporation of leguminous forages such as Leucaena leucocephala, in the diet of ruminants, can stimulate rumen function by providing protein-rich forage (Barros-Rodriguez et al. 2012). This increases the availability of compounds such as ammonia, amino acids and peptides as well as branched short-chain fatty acids, which are produced as a result of degradation of proteins. These substances promote fibre breakdown by acting as ruminal growth activators for rumen bacteria, especially cellulolytic bacteria (Hoover and Stokes 1991). This study aimed to evaluate the effects of 2 intake levels of L. leucocephala on rumen function of sheep fed Pennisetum purpureum

Evaluación de Tecnologías Sanitarias en Centroamérica

Health systems in Central America are divided into different sectors, however, each sector has in common the provision of health services, this process links medical care with other actions such as diagnosis and therapy. Therapy as the main tool for disease prevention, healing and health maintenance, has evolved bringing with it innovation, which generally manifests itself with better health outcomes for patients, however, for some years the question has been raised about the value that these health outcomes represent at an individual, collective and health system level. To resolve this problem, health technology assessment has been incorporated into health systems as a tool to reduce uncertainty regarding the benefit to the user and the financing impact of the use of a new technology.Los sistemas de salud en Centroamérica están conformados por diferentes sectores, sin embargo, cada sector tiene en común la prestación de servicios de salud, este proceso vincula la atención médica con otras acciones como lo son el diagnóstico y la terapéutica.

Para abordar esta problemática se ha incorporado a los sistemas de salud, la evaluación de tecnologías sanitarias como herramienta para disminuir la incertidumbre en cuanto al beneficio hacia el usuario y el impacto al financiador del uso de una nueva tecnología

Engineering of III-Nitride Semiconductors on Low Temperature Co-fired Ceramics

This work presents results in the feld of advanced substrate solutions in order to achieve high crystalline quality group-III nitrides based heterostructures for high frequency and power devices or for sensor applications. With that objective, Low Temperature Co-fred Ceramics has been used, as a noncrystalline substrate. Structures like these have never been developed before, and for economic reasons will represent a groundbreaking material in these felds of Electronic. In this sense, the report presents the characterization through various techniques of three series of specimens where GaN was deposited on this ceramic composite, using diferent bufer layers, and a singular metal-organic chemical vapor deposition related technique for low temperature deposition. Other single crystalline ceramic-based templates were also utilized as substrate materials, for comparison purposes

Impact of COVID-19 pandemic on cardiometabolic patients without SARS CoV-2 infection in Latin America

A cross-sectional survey including 38 questions about demography, clinical condition, changes in health habits, and medical treatments for cardiometabolic patients in outpatient follow-up was conducted. From June 15 to July 15, 2020, a total of 13 Latin-American countries participated in enrolling patients. These countries were divided into 3 geographic regions: Region 1 including North, Central, and Caribbean Regions (NCCR), Region 2 including the Andean Region (AR), and Region 3 including the Southern Cone Region (SCR). 4.216 patients were analyzed, resulting in a coefficient of 33.82%, 32.23%, and 33.94% for NCCR, AR, and SCR, respectively. Significant differences were found between the AR, SCR, and NCCR regions. The analysis of habitual medication usage showed that discontinued use of medication was more present in AR, reaching almost 30% (p < 0.001). The main finding of this study was the negative impact that restrictive measures have on adherence to medications and physical activity: Rs = 0.84 (p = 0.0003) and Rs = 0.61 (p = 0.0032), respectively. AR was the most vulnerable region. Restrictive quarantine measures imposed by the different countries showed a positive correlation with medication discontinuation and a negative correlation with physical activity levels in patients analyzed. These findings characterize the impact of the consequences left by this pandemic. Undoubtedly, restrictive measures have been and will continue to have reverberating negative effects in most Latin-American countries.Fil: Camiletti, Jorge.
