Efeito da temperatura de secagem nas características do bagaço de abacaxi e sua aplicação em biscoitos amanteigados Pineapple processing for pulp production generates a large amount of residue — specifically, the pomace — which, once dehydrated, can serve as an ingredient in bakery products. Thus, this study aimed to investigate the effect of drying temperature on the characteristics of pineapple pomace and to utilize it in the production of butter cookies. The residue was dried via convection at temperatures of 70, 80, and 90°C and subjected to physicochemical characterization. The optimal dehydrated sample was selected for incorporation into cookies at concentrations of 0%, 3%, 6%, and 9%; following baking, the cookies underwent nutritional analysis. The results indicated that drying temperature significantly influenced (p<0.05) most pomace parameters, reducing moisture content and concentrating macro- and micro-elements. Ascorbic acid content increased up to 80°C, remaining constant (p>0.05) at the subsequent temperature. Total titratable acidity (TTA), total soluble solids (TSS), total sugars, and nonreducing sugars increased progressively, whereas pH, the TSS/TTA ratio, and reducing sugars remained stable (p>0.05). The sample dried at 80°C was deemed the best due to higher ascorbic acid retention, suggesting the preservation of other heat-sensitive compounds. In the cookies, the addition of pomace reduced moisture, lipid, and protein content, as well as energy value and sample diameter, while increasing ash and carbohydrate content. Color was also affected, exhibiting more yellowish and darker tones as the residue content increased. It was concluded that the use of pineapple bagasse in butter cookies is feasible, representing a sustainable alternative for the utilization of this by-product.

A utilização do laboratório de informática nas escolas municipais de Natal The present work aims to identify and analyze the usability of computer labs, highlighting the possible benefits and challenges for the insertion of Digital Information and Communication Technologies (TDIC) in the teaching-learning process. The locus of this research was the municipal public schools, in the Potengi neighborhood, north of Natal/RN. Authors such as Pelegrinelli(2017), Löbler(2012) and Azevedo(2020), based our research and analysis that focused on understanding the current use of computer labs in these schools. A qualitative research that resulted in an identification and reflection about the current situation of computer labs in the municipal public education network of Natal/RN. To this end, we count on the participation of managers and professors in the reflection on the laboratory, its relationship with the subjects of the curricular matrix, the professional who leads this space and its purpose.

Enchentes em Alto do Rodrigues-RN ocorridas durante os anos 2008/2009: gestão de risco, impactos e memória social Alto do Rodrigues, a municipality in the state of Rio Grande do Norte, Brazil, experienced extreme flooding events between 2008 and 2009. The region's topographical characteristics, combined with weather patterns that favor intense and prolonged rainfall, contribute significantly to the occurrence of floods affecting both the population and local infrastructure. Consequently, rainwater accumulates in urban and rural areas, causing inundations that compromise the safety and quality of life of residents. Regarding infrastructure, these events can cause severe damage to roads, bridges, and buildings, resulting in financial losses for both the public sector and the population. Furthermore, the floods cause significant losses in agriculture, one of the region's primary economic activities. In this context, preventing future flooding episodes in Alto do Rodrigues poses a major challenge, requiring integrated action from local authorities, water resource management specialists, and the community at large. Adopting medium- and long-term strategies is essential to mitigate these events, ensuring a better quality of life for the population and reducing damage to public and private assets. The study’s objectives were met by highlighting the impacts of the 2008/2009 floods in Alto do Rodrigues. The methodology adopted—based on historical analyses and climate data—yielded consistent results revealing significant damage to infrastructure, agriculture, and the population's quality of life. The conclusions pointed to the need for integrated public policies and medium- to long-term strategies. Thus, the final remarks emphasize that this work does not merely describe a past event but contributes to developing solutions aimed at preventing future episodes, thereby ensuring greater safety and well-being for the community.

Desenvolvimento do aplicativo Gym Tracker

Desenvolvimento do aplicativo Gym Tracker Training consistently requires logging exercises, sets, and routines, but many people struggle to maintain an organized history and update workouts conveniently, especially when offline or needing to correct past records. To address this problem, this work proposes the development of a mobile application that facilitates workout planning, logging, and tracking, allowing users to create and reuse routines, adjust exercises and sets, and register workouts retroactively. The solution was built following an incremental process, with requirements elicitation and prioritization, data and use-case modeling, and implementation in Flutter using reactive state management and local persistence in a local-first approach, ensuring operation without continuous network dependency. The application was validated through manual testing on real Android devices, which verified the integrity of operations and data consistency, demonstrating technical feasibility, reliable offline functionality, correct history maintenance, and adherence to the defined requirements.
