Bravo. 2023. “Markov Triples with Generalized Pell Numbers”. Mathematics 2024, Vol. 12, Page 108 12(1):108. doi: 10.3390/MATH12010108. | For an integer k ≥ 2, let (Pn(k))n be the k-generalized Pell sequence which starts with 0, . . . , 0, 1 (k terms), and each term afterwards is given by Pn(k)=2Pn−1(k)+Pn−2(k)+ · · · + Pn−k(k). In this paper, we determine all solutions of the Markov equation x2+y2+z2 = 3xyz, with x, y, and z being k-generalized Pell numbers. This paper continues and extends a previous work of Kafle, Srinivasan and Togbé, who found all Markov triples with Pell components. | A1 | Universidad del Cauca |
| 2 | Eduardo Argote Ortíz | Héctor Samuel Villada Castillo | Development of biocomposites based on cassava bagasse and coconut fiber for substituting plastic pots: Evaluation of physical-mechanical, morphological and structural properties | Ortiz, E.A. et al. (2025) ‘Development of biocomposites based on cassava bagasse and coconut fiber for substituting plastic pots: Evaluation of physical-mechanical, morphological and structural properties’, Materials Chemistry and Physics, p. 130697. doi:10.1016/j.matchemphys.2025.130697. | The excessive use of plastic materials has negatively impacted the environment, aquifers, and terrestrial ecosystems, leading to the development of composite materials from natural, renewable sources, and agricultural waste, among others. For this reason, a biocomposite (BM) material was developed from cassava bagasse (CB) with coconut fiber (CF) for application in the production and subsequent replacement of plastic pots (PP). Firstly, thermal, morphological, mechanical, and water absorption characterization of the FC showed that it is thermally stable up to approximately 250 °C. BM was then manufactured from gelatinized cassava bagasse (GCB) with different CF contents (20, 27.5, 35, 42.5, and 50 %) by a mix design using the compression molding technique. In this step, the flexural mechanical properties and water absorption were evaluated, finding a reduction in water absorption and an increase in mechanical properties with 63 % GCB and 37 % CF, due to a higher interfacial bonding between the fibers and the matrix. Consequently, it could be established that FC strengthens BM since the characterization techniques evidenced the formation of new chemical structures and intermolecular bonds. In addition, using two agro-industrial wastes to form the BM contributes to reducing the environmental impact, because they come from renewable sources and are environmentally friendly. | A1 | Universidad del Cauca |
| 3 | Cristian Alexis Lasso Quilindo | Luz Marina Chalapud Narváez | Effect of 4 Weeks of High-Intensity Interval Training (HIIT) on VO2max, Anaerobic Power, and Specific Performance in Cyclists with Cerebral Palsy | Lasso-Quilindo, C.A. et al. (2025) ‘Effect of 4 weeks of high-intensity interval training (HIIT) on VO2max, anaerobic power, and specific performance in cyclists with Cerebral Palsy’, Journal of Functional Morphology and Kinesiology, 10(2), p. 102. doi:10.3390/jfmk10020102. | Background: High-intensity interval training (HIIT) is an effective and efficient method for training Paralympic athletes with cerebral palsy, particularly in intermittent sports and those requiring aerobic and anaerobic capacity, speed, and strength to delay fatigue onset and optimize athletic performance. Objectives: This study aimed to analyze the effects of four weeks of HIIT on the estimated VO2max, anaerobic power, and athletic performance in cyclists with cerebral palsy. Materials and Methods: This quasi-experimental study included three male athletes (Athletes A, B, and C) with cerebral palsy from the Paracycling Departmental Commission of Cauca, Colombia. The estimated VO2max was assessed using an incremental test on a cycling ergometer. Anaerobic power was measured using the 30 s long Wingate Anaerobic Test (WAnT_30 s. Specific performance was evaluated with an individual time trial of 14 km for class T1 and 20 km for class T2. HIIT training was performed on a cycling ergometer over four weeks (two sessions per week). The training intensity was based on watts (W) measured in the incremental test for long HIIT sessions and in the WAnT_30 s test for short HIIT sessions. The training load was monitored through heart rate (HR) responses and the subjective perceived exertion (RPE) at the end of the training. Results: After the HIIT intervention, percentage changes in the estimated VO2max were observed in Athlete A (+7%) and Athlete C (+9.4%). In the WAnT_30 s, there were increases in the maximal and mean power in Athlete A (>31%, 282.3 vs. 370.4 W), Athlete B (>15%, 272.5 vs. 312.6 W), and Athlete C (>9%, 473.7 vs. 516.2 W). Individual time trial performance improved, with reduced completion times for Athlete A (−6.7%, 2492 vs. 2325 s), Athlete B (−3.7%, 2486 vs. 2390 s), and Athlete C (−3.7%, 2775 vs. 2674 s). Conclusions: This study found that eight sessions of high-intensity interval training (HIIT) over a four-week period had a positive effect on the estimated VO2max in Athletes A and C. Moreover, all three paracyclists demonstrated improvements in their maximal and average power output during the 30 s Wingate Anaerobic Test (WAnT_30 s), as well as enhanced performance in the time trial test. | A1 | Corporación Universitaria Autónoma del Cauca |

Una revisión narrativa | Lasso Quilindo, Cristian Alexis, and Luz Marina Chalapud Narváez. 2024. “Entrenamiento Interválico de Alta Intensidad (HIIT) En Deportistas Paralímpicos. Una Revisión Narrativa (High Intensity Interval Training (HIIT) in Paralympic Athletes. A Narrative Review).” Retos 51:1431–41. doi: 10.47197/RETOS.V51.101379. | Introduction: High intensity interval training (HIIT) has gained space as a training methodology applied in the field of Paralympic sport in athletes with physical and visual disabilities and cerebral palsy, showing favorable effects on physical fitness and sports performance. This training method uses high intensity intervals with periods of active or passive recovery at low intensity to work on body composition, aerobic capacity, muscular strength, speed, psychological changes and performance in Paralympic sports. Objective: To conduct a narrative review on the effects of the HIIT method in Paralympic athletes. Methodology: With a search strategy in a temporal window of 10 years (2013-2023), the exploration of articles in the databases PubMed, SciencieDirect, SPORTDiscus, Scopus, Dialnet and Google Scholar was carried out, using inclusion-exclusion criteria. Results: Eleven studies were included in collective and individual Paralympic sports, of which seven showed improvements in some of the psychological variables, physical condition and sports performance. Of the total number of studies, there are for in which no improvement was presented. Conclusions: It is highlighted that the HIIT method produces favorable effects on aerobic and anaerobic capacity, body composition and increased recruitment of muscle fibers when combined with strength and sprint training, with a prolonged periodization that benefits the physical condition and sports performance of para-athletes. Research is needed in other Paralympic sports, with larger homogeneous samples and extended training periods. | A2 | Corporación Universitaria Autónoma del Cauca |

The tests were carried out under composting conditions. The kinetics of carbon dioxide production and the percentage of biodegradation were measured. Fourier Transform InfraRed spectroscopy (FTIR), Thermo Gravimetric Analysis (TGA), and Scanning Electron Microscopy (SEM) were used to study changes of the films in the biodegradation test. The total organic carbon (TOC) was measured. After the biodegradation test, plant growth tests were carried out, which included measurement of chlorophyll Index (CI). The results showed that the flexible film, ecovio F2223, and thermoplastic starch (TPS) achieved biodegradation of 92.13%, 93.20%, and 96.88%, respectively, in contrast to the polylactic acid-PLA (80.28%). The FTIR showed changes in molecular structures, mainly in band crystalline zones around 2800–3000 cm−1, deformation bands between 1400 and 1500 cm−1 and in amorphous zones band of 1200–1000 cm−1. TGA to flexible films, PLA, ecovio F2223, and TPS showed a thermal degradation around 350°C, 360°C, 370°C, and 320°C, due to polymeric structures degradation. SEM micrographs show morphology change on the films surfaces after the biodegradation test, evidencing the action of microorganisms. The plant growth tests showed the compost stability by Gemination percentage and CI no presented significative differences. | A2 | Universidad del Cauca |

In response to this, the State enacted Law 1448 of 2011, which establishes procedures to provide reparations to victims. Land restitution aims for the population to return to the land that was taken from them; however, the return has generated many challenges for the State and for the repaired population. Therefore, the research analyzed the difficulties of the repaired population for the safe and effective return to therestituted lands in the department of Cauca, based on a methodology that triangulated the results of an institutional aggregate data strategy to establish the impact of the armed conflict, and a qualitative one with interviews to institutional actors and victims to determine the difficulties of return. The findings indicated that the population of Cauca presents challenges to return due to the absence of goods and services in rural areas, territorial conflicts, economic and security conditions. It is concluded that, despite the high volume of sentences that restitute goods, as long as the armed conflict persists, the countryside will not have the conditions to guarantee quality of life for the population, and return will be a complex task. | B | Corporación Universitaria Autónoma del Cauca |

The use of satellite images, particularly those obtained by the MODIS sensor, is essential for obtaining accurate data. However, the high cloud cover, which is common in Colombian geography, affects the quality and availability of these images for much of the year, creating gaps in critical data for assessing the state of marine ecosystems. This work proposes a deep learning algorithm based on time series for predicting missing chlorophyll-a values. The presented methodology overcomes the limitations imposed by cloud cover, achieving an R2 accuracy above 0.8 in one of the models. In this specific context, the implementation and evaluation of various deep learning models have proven to be effective alternatives in providing a more accurate and continuous assessment of fishing areas. This offers valuable information to improve the management and sustainability of the fishing sector in Colombia by adding a temporal component to the prediction of chlorophyll-a values, using data from up to three months prior to the target feature. | B | Corporación Universitaria Comfacauca |

MgO-NPs were synthesized using a chemical route and characterized with IR spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and EDAX spectroscopy. The results indicated that the only crystalline phase present in the synthesized solid was periclase-type MgO, with high chemical purity and nanoscale size (<100 nm). When evaluating the effect of MgO-NPs on V. unguiculata, it was observed that they reduced the number of days to flowering (up to 70.5 ± 6.0 days) and increased the accumulated number of pods per plant (up to 7.0 ± 0.8 pods). Additionally, these oxidenanoparticles caused a decrease in stem dry mass. According to the results, MgO-NPs supplied to V. unguiculata through nanopriming can become an efficient way to provide an essential element like Mg, thus serving their function as nanofertilizer. | B | Universidad del Cauca |

Revista UIS Ingenierías. | The article focuses on a technical feasibility analysis of DC microgrids for implementation in non-interconnected areas of Colombia, especially in the region of Chancón Playa (Timbiquí) in the Caucano Pacific, with a priority focus on food conservation. A radial DC microgrid topology is chosen due to its simplicity and expandability. Then, a Matlab-Simulink simulation is carried out to design a microgrid that includes solar photovoltaic generation, battery backup, power converters and a DC load composed of 4 DC refrigerators. The paper also analyzes the behavior of the microgrid with the DC load and describes the implementation of a control system based on the incremental conductance algorithm. The simulation confirms the potential of DC microgrids to meet energy needs in isolated areas, supporting the technical feasibility of providing a reliable energy supply in these areas. | B | Universidad del Cauca |

Employing a mixed methodology using techniques such as documentary review, review of statistical techniques of automatic learning, search algorithms and computational linguistics, it is taken into consideration that women in this area differ from what is considered by the legal norm on what it is to be a rural woman and aim to apply their own definitions based on their processes of care and support. The approach to agricultural work permeated by an indigenous environmental awareness leads to consider that rural women perceive themselves from an approach different from that referred to in Law 732 of 2002 (Law on rural women in Colombia), allowing to consider their relationship with rurality through care work that gives emotional meaning to their life plans, their family and their commitment to the territory. | B | Corporación Universitaria Autónoma del Cauca |

For this, a methodology under a mixed focus was adopted. First, a qualitative perspective was introduced through document analysis and interviews and, second, a quantitative approach was used with the instrumentalization of techniques such as aggregate data analysis of official entities and non-probabilistic sampling. The Colombian legal system has recognized through jurisprudence the foster family figure, as well as their right to access the survivor's pension. However, the pension administration entities Still prevent access to this benefit to the members of foster families. | C | Corporación Universitaria Autónoma del Cauca |

The objective of the study was to analyze the impact of Parkour on the physical, emotional, and social development of young people in urban contexts by reviewing the available literature to identify the main benefits and challenges of its practice. The methodological design was based on a bibliographic review with a narrative review approach, through the search for scientific articles in databases such as SportDiscus, Dialnet, Scielo, ScienceDirect, and Google Scholar. The results indicate that Parkour improves cardiovascular endurance, strengthens functional muscle groups, fosters meaningful social relationships and a sense of belonging, in addition to facilitating emotional expression and confronting constant challenges. It also contributes to self-expression and individuality, being some of the main benefits of this urban sport. It is concluded that Parkour helps young people overcome obstacles both in their urban environment and in their personal lives, offering a unique perspective on life in the 21st century. | C | Corporación Universitaria Autónoma del Cauca |

The research was carried out in three phases: in the first phase, a communication diagnosis was conducted to identify the needs and limitations in the project's dissemination through in-depth interviews, participant observation, and a SWOT analysis. In the second phase, a document review and analysis of methodological models related to transmedia narratives were carried out, which allowed for the definition of narrative lines and the structuring of the proposal. Finally, in the third phase, the proposal was validated through a transmedia narrative manual that included a proof of concept and the use of a Likert scale evaluation with the project team. The results showed that transmedia narratives are an effective tool for making scientific content more accessible, dynamic, and participatory, facilitating its appropriation by diverse audiences. The research concluded that the transmedia approach not only strengthens public communication of science but also fosters the construction of connections between the scientific community and society, promoting greater understanding and participation in technological and scientific innovation processes. | C | Universidad del Cauca |

These two characteristics are key to providing quality software products. However, small software development companies do not have the personnel, knowledge, tools, and time necessary to carry out the evaluation process of these characteristics, resulting in the omission of these evaluations in the software development processes. The purpose of building a lightweight method is that within the software development process of small companies, it is possible to execute in a guided, simple, and correct way the usability and accessibility evaluations. For the construction of this method, the Situational Method Engineering-SME was used, resulting in the structure of the method, which consists of 5 activities with their respective tasks and formats, being subjected to expert evaluation validating its ease of use, usefulness, and completeness, obtaining as a result that it is a method moderately easy to use, useful, and complete, with elements of its structure that should be improved. Additionally, its ease of use and completeness were validated in a case study, obtaining an optimal response in the process. | D | Corporación Universitaria Comfacauca |

Fibers, such as coconut fibers, have been shown to improve these compounds' properties significantly. In this study, natural coir fibers (NCF) treated with different chemical and physical processes, such as sodium hydroxide (NaOH), sodium hypochlorite (NaOCl), and ultrasound (U), were analyzed. Structural, morphological and water absorption properties were tested by infrared spectroscopy, water absorption and X-ray diffraction tests. These indicated that treated fibers show a decrease or loss of transmittance bands associated with lignin, hemicellulose and a higher concentration of cellulose bands. Thus, higher water absorption and an increase in the crystallinity index were observed, which enhances its reinforcing capacity and improves the interaction between a polymeric matrix and the fibers. It also highlights the potential for the use of agroindustrial waste under a circular economy approach, promoting its incorporation into new sustainable products. | D | Universidad del Cauca |

This study evaluated the biological and chemical stability of three composts with different compositions and origins: Finca La Rejoya, Granja Integral Mamá Lombriz, and a commercial compost (Abonisa). Biological stability was assessed through a germination test using native corn seeds, tolerance tests with wheat seedlings (evaluating seed yield, plant height, root length, and chlorophyll index), and quantification of carbon dioxide (CO₂) production. Chemical stability was analyzed by measuring total organic carbon (TOC), nitrogen content, carbon/nitrogen (C/N) ratio, total solids (TS), volatile solids (VS), and pH. The results revealed statistically significant differences among the composts. The compost from Finca La Rejoya exhibited optimal conditions, with a germination rate of 88.89%, a seed yield of 95.74%, the highest chlorophyll index (1.83), the lowest CO₂ production (150.26 mL after 48 hours), a C/N ratio of 13.36, and a pH of 7.11. This study emphasizes the importance of evaluating compost stability before using it in aerobic biodegradation tests and concludes that the compost from Finca La Rejoya is the most suitable as an inoculum for such applications. | D | Universidad del Cauca |
