Phthalic anhydride (PA) is a key industrial compound, particularly relevant for the large-scale production of plasticizers. This study aimed to develop the conceptual design of a proposed PA production process using the ChemCAD 7.1.2 simulation software, in which maleic anhydride (MA) wasidentified as the principal byproduct. Several parameters were obtained for the heat exchangers, including heat curves, heat duty, logarithmic mean temperature difference (LMTD), and overall heat transfer coefficient. Additionally, the mass flow rate and composition of the main process streams were determined through simulation, along with their temperature, pressure, and vapor fraction. Design parameters for both distillation columns were also calculated, as well as the heat duty of the catalytic reactor.Finally, the total purchase and installation costs of selected equipment were estimated. The mass flow rate of the bottom stream from the purification column was 10,921.083 kg/h, composed primarily of PA (99.19% purity) and o-xylene (0.80%), while MA was recovered in the top stream with a mass flow rate of 973.342 kg/h and a purity of 83.36%.

BackgroundAging is a physiological process characterized by several metabolic changes, oxidative stress and inflammatory processes accumulated throughout life, reflecting in several diseases. Adopting a healthy lifestyle, including a diet rich in polyphenols, can play a crucial role in promoting healthy aging, since these compounds are capable of regulating several signaling pathways as well as modulating the intestinal microbiota and being involved in epigenetic modifications. With the advancement of technology and omics sciences, the food industry is undergoing a rapid transformation toward personalizing and customizing nutritional solutions that consider each individual’s health conditions, preferences, and lifestyles. Therefore, such niche that will become predominant worldwide.Scope and approachThe scope of this review focuses on the role of polyphenols in diseases related to aging, providing an overview of alternatives for personalized nutritional plans, including the role of the food industry in the technological era to meet the unique needs and to develop new food products for the elderly population.Key findings and conclusionFood products for older people represent opportunities in a niche that will become predominant worldwide. In this sense new technologies offers new possibilities for innovation in the food industry production chain that aim to improve not only the nutritional characteristics of foods but also improvements in food processing, food safety, and quality assurance.

The objective of this research was to assess the phytoplankton diversity of San Pablo Lake and, based on its composition, determine its current trophic status. Samples were collected from May to August 2023 to account for seasonal variations. Taxonomic identification and photographic records were obtained using an inverted microscope equipped with a camera. A total of 77 species of microalgae and cyanobacteria, belonging to eight phyla, were identified. The most representative groups were Heterokontophyta (31 % of total species), followed by Chlorophyta (25%) and Charophyta (17 %). Cell density peaked in May, reaching 75,535 org/mL, coinciding with the highest rainfall levels. Microcystis aeruginosa, a potentially toxic cyanobacterium, was detected. Nitrogen and total phosphorus levels were elevated compared to other lentic ecosystems in the region. The saprobic index and organic pollution index confirm significant contamination and high organic pollution in San Pablo Lake, classifying it as eutrophic.

Els robots conversacionals o bots ja estan entre nosaltres. Tractem amb ells amb freqüència quan cridem al servei d'atenció al client d'una empresa, en concertar una cita mèdica en línia o quan sol·licitem informació en una pàgina web. Es tracta d'una tecnologia que permet que les organitzacions donin resposta fàcilment a molts tipus de consultes i problemes freqüents que presenten els clients. Els consumidors a poc a poc ens anem acostumant a tractar amb robots i els acceptem com un canal de comunicació habitual amb les companyies. Els bots aporten escalabilitat a l'empresa i la capacitat de personalitzar el seu marc de relacions i permeten interactuar amb un nombre il·limitat de clients alhora. Des del punt de vista de l'usuari, aquests serveis resulten molt efectius per a buscar informació útil de forma molt més ràpida i senzilla que navegant per llocs web o buscant en grans repositoris de dades. D'altra banda, permeten automatitzar les comunicacions individuals i personalitzar-les utilitzant informació de l'usuari mitjançant el plantejament de preguntes que ajuden a crear un context per al client. El present treball pretén acostar al lector al món del bot d'una forma divulgativa sense entrar en excessius tecnicismes. Per a això, s'ha partit d'una explicació de la tecnologia bàsica que permet que funcionin aquest tipus d'assistents, per a posteriorment explicar la seva utilitat real en les empreses i institucions.

O presente livro tem por objetivo disseminar resultados de estudos e pesquisas sobre Inclusão e Acessibilidade no Ensino Superior divididos em dois grandes eixos:A) Políticas de Inclusão no Ensino Superior: aborda acerca das Políticas de Inclusão neste nível de ensino. À luz do fenômeno social da deficiência, em uma mirada interseccional, discorre sobre os modos de opressão que afetam vidas de diferentes coletivos, dentre os quais se reconhecem e/ou identificam os em situação de deficiência. Ainda, aponta indicadores de avaliação da qualidade da educação capazes de orientar desenhos e políticas institucionais inclusivas em diferentes contextos nacionais e internacionais no ensino superior.B) Práticas Inclusivas no Ensino Superior: aborda diferentes formatos de práticas inclusivas no contexto universitário; discorre sobre a utilização de recursos tecnológicos para promover acessibilidade e inclusão de diferentes coletivos e, aponta ainda, relatos de experiência de práticas inclusivas no ensino superior.Dessa forma, reúne estudos e experiências que iluminam os múltiplos caminhos possíveis para a construção de um ensino superior mais inclusivo, acessível e comprometido com a justiça social.
