This study aims to compare the feedback provided by human professors and ChatGPT on university students’ work and to report on students’ perceptions of both types of feedback. A systematic review was conducted following PRISMA 2020 guidelines. Databases research included Web of Science, Scopus, EBSCO, ACM Digital Library, and IEEE Xplore, with additional gray literature sources, until October 2024. Inclusion criteria were cross-sectional studies evaluating university students’ work, comparing feedback from ChatGPT with human professors. Data extraction was performed using a standardized form, and risk of bias was assessed with the Joanna Briggs Institute critical appraisal tool. A narrative synthesis of the results was made. PROSPERO registration number: CRD42024566691. This review included 8 studies with 461 students. ChatGPT feedback was detailed and rapid, while human feedback was valued for its personalization and emotional support. Students appreciated the detailed and immediate nature of ChatGPT feedback but noted its lack of emotional nuance and context-specific guidance. Human feedback was preferred for addressing individual learning needs and providing affective support. A combination of both types of feedback to maximize benefits. ChatGPT can assist human teachers by providing detailed and timely feedback to university students. However, human supervision is essential to ensure feedback is nuanced and contextually appropriate. A hybrid approach can optimize the learning experience in higher education. Further research is necessary to explore AI applications in educational settings and understand their impact on learning outcomes.

Functional beverages with added health benefits are popular among peoples and athletes because they help them recover faster from intense workouts and perform better overall. This research set out to determine how well heat-treated stem juice from Oxalis tuberosa Mol. “oca” and fruit juice from Gaultheria glomerata (Cav.) Sleumer “laqa-laqa” performed as an antioxidant in a functional drink. The “oca” stems and the “laqa-laqa” fruit were collected to obtain the juice. For this study, 30 semi-trained panellists used sensory evaluation to rate four treatments (Bo, B1, B2, and B3) with varying quantities of “oca” and “laqa-laqa” juice. The results concluded that the treatment B2, which included 300 ml of “oca” stem juice, 800 ml of “laqa-laqa” juice, 1000 ml of treated water, and 220 g of refined sugar, was given the highest score after a physicochemical evaluation of its colour, smell, taste, and overall appearance. Similarly, the results showed that the protein content increased by 1.38%, the fat content by 1.08%, the moisture percentage by 99.5%, the ash content by 1.82%, and the carbohydrate content by 6.22% after B2 treatment. Similarly, results revealed significant enhancement in antioxidant profiling such as total polyphenols: 1825 mg of gallic acid/100 g and antioxidant Activity: 89.56% μmol of trolox /100 g. In conclusion, due to its high energy content and antioxidant activity, it may be a viable nutritional option for athletes who engage in rigorous, frequent physical exertion.

Objective: The objective of this study was a review to compile research on phytoremediation methods—including phytoextraction, rhizofiltration, phytostabilisation, phytodegradation, and phytovolatilisation—using primary sources to address heavy metal contamination in water. Theoretical Framework: The study is a basic investigation that includes a contextualization regarding the water issue, as well as the treatment of wastewater. A description of the characteristics and quality indicators of water was carried out, along with the importance of the removal of contaminants such as heavy metals using different technologies like phytoextraction, rhizofiltration, phytostabilization, phytodegradation, and phytovolatilization. This led to a detailed description of artificial wetland techniques as a viable and sustainable alternative. Method: The methodology adopted for this research includes data collection and compilation of existing information; regarding the different techniques related to wastewater treatment with artificial wetlands, these systems utilize natural processes involving vegetation, soil, and microbial activity to remove contaminants from water. More than 100 articles have been legally downloaded, and systematised in the database to paraphrase sentences and cite appropriately. Results and Discussion: Phytoremediation is an environmentally friendly technical choice because of its low cost to remediate water and soil contamination through methods of phytoextraction, rhizofiltration, phytostabilisation, phytodegradation and phytovolatilisation for organic contaminants, pesticides, oil waste, heavy metals, antibiotics, etc. It is relevant to choose transgenic plant methods to insert DNA genes and conduct molecular mechanisms through experimental optimisation studies for lightened growth and hyperaccumulation of heavy metals, generating space for metal and biomass storage, and prior knowledge of the physiology and biochemical processes of the plants. Research Implications: The results can be applied or influence practices in environmental protection using Phytoremediation, which is based on a natural technique of plants and their microbiota associated with roots and tissues, endophytic bacteria as Aeromonas sp, Pseudomonas sp, Bacillus sp, Sinorhizobium meliloti, Chryseomonas sp, Curtobacterium sp, Sphingomonas sp, Erwinia sp, Flavimonas sp retain contaminants. On the other hand, aquatic macrophytes such as Lemna spp, Typha spp, Potamogeton spp, Azolla filiculoides, Ceratophyllum demersm, Eichhornia crassipes, and Phragmites australis constitute an effective and feasible complementary alternative for the treatment of contaminated waters. Originality/Value: This study contributes to the literature There are different phytoremediation methods such as phytoextraction, rhizofiltration, phytostabilisation, phytodegradation, and hytovolatilisation for organic contaminants, pesticides, petroleum waste, heavy metals, pharmaceutical antibiotics, etc. Each of the elements has specific applications depending on the conditions of the place and the type of contaminants in an ecosystem.

Se puede observar que año tras año la incidencia de energía solar se incrementa llegando a sobrepasar los valores máximos permitidos. Dentro de los parámetros espectográficos de radiación solar se encuentran los rayos ultravioletas. Médicos especialistas en el tratamiento de la piel han demostrado que la exposición prolongada a los rayos solares puede generar enfermedades a la piel por lo que se recomienda tener toda una serie de cuidados y protecciones. Actualmente no existe ningún dispositivo en la ciudad de Juliaca, que mida la incidencia de los rayos UV en la superficie en tiempo real y que muestre los resultados a través de una interface amigable para que cualquier persona pueda ver y entender los niveles a los que se está exponiendo. Para cumplir ese objetivo se ha implementado un dispositivo que se encargue de medir y evaluar los niveles de radiación solar en el transcurso del día y a través de un display y/o una señalización de colores pueda mostrar los niveles de radiación solar que existe en la zona. Se diseñó un dispositivo con sensores UV que sea capaz de recibir y almacenar los valores en una tarjeta micro SD. A través de un display montado en una estructura rígida, los datos registrados en el transcurso del día son mostrados y acompañados de una señalización de colores el cual indica el nivel de radiación solar en tiempo real. Finalmente se espera obtener un dispositivo que pueda ser fácil de replicar para que sea instalado en diversos puntos de la ciudad universitaria donde los estudiantes puedan observar y tengan conocimiento acerca de los riesgos y cuidados que se deben tener bajo el sol.

The consumption of products with high nutritional value and antioxidant capacity has increased notably in recent years. Due to health problems such as triglycerides and cardiovascular problems, its use is becoming reduced. So that, chia (Salvia hispánica) and sachatomate (Cyphomandra betacea) have gained interest as an alternative to develop nutraceutical products, compared to conventional products. The objective of the study was to determine the effect of the partial substitution of mango (Mangifera indica) and ground chia (Salvia hispánica) on the antioxidant capacity in the elaboration of nectar based on Sachatomate. The physicochemical characteristics were determined where sample 11 complies with the established parameters: 13.4° Brix, pH 4.323, 0.354 of C₆-H₈-O₇ and viscosity 3967.3 mPas, according to the NTP 203.110 standard. Regarding the antioxidant capacity, sample 12 was the most optimal, according to the DPPH method, it has been determined 104.3 micromoles Trolox equivalents; according to the ABTS method, it was determined with an antioxidant content of 187.4 micromoles Trolox equivalents. Regarding the proximal chemical evaluation, sample 12 was determined to be the most suitable with a moisture percentage of 87.45%, ash 0.32%, crude fiber 0.09%, fat 0.10%, protein 0.45% and carbohydrates 11.59%. Concluding that substituting sachatomate and ground chia significantly influences the antioxidant capacity, increasing to 104.3 and 187.4 micromoles Trolox equivalents, determined by both methods, indicates that nectar consumption can be used to improve the health of consumers.

Bioavailability of nutrients, the scarcity of synthetic fertilisers, and the rising cost of fuel have all contributed to an increase in production costs, which has in turn reduced crop productivity and led scientists to seek out new methods to ensure high-quality output. In this context, various cytokinins dosages were tested in Peru to see whether they affected the quality of caigua, in an effort to address these issues. To mitigate these problems, a pot experiment was carried out to check the effects of various doses of cytokinin in the quality of caigua in Peru. The experiment consisted of 5 treatments including (0, 50, 100, 150 and 200 mL of cytokinin) by using (Anthesis Plus per 200 L of water) as a source, each with three replicates and placed following a randomized complete block design (RCBD). Treatment with 100 mL of cytokinins foliar analysis resulted in a caigua length of 18.9 cm, an increase in diameter of 5.65 cm, and an improvement in pulp thickness of 7.60 millimeters. Physiological parameters of caigua plants taken after 45 days of sowing were considerably improved with the same treatment. Similarly, N, K and Zn concentration in leaf was higher in case of 100 mL of cytokinins foliar analysis. Therefore, policymakers must advise using the recommended quantity of cytokinins to bring about regime transition, and formers can gain by injecting 100 mL of cytokinins to boost production and the economy. It was concluded that the adequate dose of cytokinins is in treatment T3, which raised value of potassium concentration in leaves, this influenced optimal development, strengthening against environmental stress and therefore quality. For this reason, research was carried out on the comparative study of cytokinin doses in the quality of caigua in Peru; the objective was to determine the appropriate dose to obtain higher quality fruit. Likewise, it was underlined that the objective was to employ an ecological alternative of plant origin such as the usage of phytohormone that stimulates the growth of the plant and consequently the quality of the fruit. The obtained the results were served as a recommendation for farmers in the area.
