...
Ramírez Carvajal, Luis Eduardo | 2022-01-05

A computational tool for learning electrostatic physics is presented through the development of a disruptive methodology. The tool allows the analysis of case studies based on Coulomb’s law, Gauss’s law, Poisson’s equation, and Laplace’s equation with boundary value. The tool was tested using reference exercises for each case study, making use of quantitative and qualitative comparative analysis between the traditional mathematical development and the computational tool. Errors were measured using Likert scale. The quantitative results showed errors of less than 1.8% in all the cases studied, concluding that the tool is effective. The qualitative results showed that the methodology allows a better development of the electrostatics learning process, dynamizing the study of complex topics such as electromagnetic physics theories through interactivity and technological resources, in addition to having a theoretical module developed using agile methodologies that provide dynamism and an intuitive environment to the interface.

Cultivation of Chlorella sp. for biodiesel production using two farming wastewaters in eastern Colombia
...
Urbina-Suarez, Nestor Andres | 2021-08-01

The production of biofuels using wastewater as a microalgae culture medium is a little explored technology, but with potential for success. In order to contribute to the knowledge of these technologies and their technical feasibility for microalgae growth, in this work the Chlorella sp. strain was cultivated in two types of effluents generated in an experimental farm located in eastern Colombia, before and after a biological treatment process. The consumption of the main nutrients that regulate growth and lipid production was evaluated, in order to extract, quantify, characterize and convert them into biodiesel. The results showed that Chlorella sp. growth and lipid production is more favourable in R2 medium of treated water than in R1 medium of raw water, mainly due to phosphorus limitation and higher N-NO3 concentration in R2 compared to R1. In the R2 medium culture, a percentage of 42.54% of long-chain fatty acids was found, which is necessary to obtain a high quality biodiesel. Finally, the best transesterification experiment allowed reaching a fatty acid methyl esters (FAME) percentage of 90.1 ± 2.7%. In general, the results demonstrated the potential viability of using the wastewater generated in the San Pablo farm to produce biomass with lipid content to obtain biodiesel, finding that where the concentration of nutrients, mainly nitrogen, has a great influence on the microalgal metabolism for lipid accumulation.

Different effect of nitrogen sources in autotrophic and mixotrophic culture of Scenedesmus spfor biomass and carotenoids production using acidic coal mine drainage effluents
...
Urbina-Suarez, Nestor Andres | 2021-10-30

In the present study, the conditions for an autotrophic and mixotrophic culture of Scenedesmus sp were established. Effluents from acidic coal mine drains were used to study biomass and carotenoid production, both under autotrophic and mixotrophic conditions in relation to the effect of different sources of nitrogen: sodium nitrate, urea and ammonium phosphate. Pollutant removal was determined, such as COD, TOC, heavy metals, ions and total suspended solids. Batch cultures lasted nine days and biomass production, carotenoids and pollutant removal were compared in each condition. The highest biomass concentration reached was 1.2 g/L in the mixotrophic culture with urea, followed by the culture with sodium nitrate of 0.9 g/L in a C/N ratio of 6:1. The highest carotenoid specific concentration was reached in the mixotrophic culture with sodium nitrate, 19.43 mg carotenoids /g biomass. The culture with ammonium phosphate was found to be inhibitory for the growth of the microalgae with the lowest results of all the parameters except for the autotrophic culture where the concentration of carotenoids was very similar to those reached with sodium nitrate and urea. Finally, the mixotrophic culture with urea presented the highest removal percentages, being 86.97% for total iron, 58.29% for chlorides and 92.5% for COD.

...
Pabon Galan, Carlos Antonio | 2022

The teaching of physics should be supported by practical or laboratory activities that seek to develop the scientific competencies of the students who study physics, so it is necessary to propose innovative strategies, such as research-based learning, in which students answer research questions through the analysis of data, which increases the interaction between the student and the physical concepts under investigation. Therefore, the objective of the study was to analyze the beliefs of teachers in natural science training at a public university in Colombia who take the subject of physics on research-based learning, to provide information on how to guide the use of innovative strategies. The study responds to a type of quantitative research with a descriptive approach and was based on a field design. On the other hand, the results reflect slightly positive beliefs of students in initial teacher training who study physics about researchbased learning as an innovative strategy, although it is recommended to expand the sample to generalize. Finally, the analysis reveals as a conclusion that the implementation of innovative methodologies such as inquiry-based learning for science teaching, especially physics, should be promoted and supported more effectively to foster motivation, skills development, and conceptual understanding. of the scientific contents.

Removal of Nutrients and Pesticides from Agricultural Runoff Using Microalgae and Cyanobacteria
...
Castellanos Estupiñan, Miguel A. | 2022-02-12

The use of pesticides in agriculture has ensured the production of different crops. However, pesticides have become an emerging public health problem for Latin American countries due to their excessive use, inadequate application, toxic characteristics, and minimal residue control. The current project evaluates the ability of two strains of algae (Chlorella and Scenedesmus sp.) and one cyanobacteria (Hapalosyphon sp.) to remove excess pesticides and other nutrients present in runoff water from rice production. Different concentrations of wastewater and carbon sources (Na2CO3 and NaHCO3 ) were evaluated. According to the results, all three strains can be grown in wastewater without dilution (100%), with a biomass concentration comparable to a synthetic medium. All three strains significantly reduced the concentration of NO3 and PO4 (95 and 85%, respectively), with no difference between Na2CO3 or NaHCO3 . Finally, Chlorella sp. obtained the highest removal efficiency of the pesticide (Chlorpyrifos), followed by Scenedesmus and Hapalosyphon sp. (100, 75, and 50%, respectively). This work shows that it is possible to use this type of waste as an alternative source of nutrients to obtain biomass and metabolites of interest, such as lipids and carbohydrates, to produce biofuels.

Becerra Moreno, Dorance | 2023-09-08

El tratamiento de lixiviados de rellenos sanitarios requiere de procesos que permitan la remoción eficaz de los diferentes contaminantes presentes en este tipo de residuos líquidos. Para el tratamiento de este tipo de residuos se han empleado una gran diversidad de procesos biológicos, los cuales aprovechan la capacidad de transformar los diferentes componentes del medio liquido en biomasa, sin embargo, estos procesos poseen limitaciones debido a las características intrínsecas del lixiviado. En los últimos años se ha impulsado la integración de los procesos biológicos con los Procesos Avanzados de Oxidación, lo cual permitiría reducir significativamente las características toxicas de estos residuos para así cumplir con las condiciones legales para ser vertidos al ambiente sin que se produzcan daños. En la presente revisión se investigan los trabajos recientes (2015 a 2021) referentes al tratamiento biológico y con procesos Avanzados de Oxidación (basados en ozono, procesos electroquímicos y fotocatálisis). Estos procesos se analizan en combinación, para describir las condiciones óptimas en las que se reducen las cargas contaminantes de los lixiviados de rellenos sanitarios. Finalmente es posible identificar que los procesos de tratamiento en estudio son tecnologías que pueden ser acopladas, registrando mayor eficacia y menor generación de subproductos de desecho o lodos

Strengthening Critical Thinking in Engineering Students through Mathematics: The Power of Attitudes
...
PLAZA GÁLVEZ, LUIS FERNANDO | 2023-07-31

This study aims to strengthen critical thinking in future engineers through mathematics by stimulating their attitudes. To achieve this, a qualitative informative study will be conducted with a characteristic cut and a deductive orientation through the analysis and synthesis of contents from scientific publications specializing in the development of critical thinking. This type of thinking can be strengthened through strategies proposed by the mathematics teacher, allowing an increase in curiosity, eagerness to learn and inquire, and especially promoting and awakening curiosity in students through contexts where mathematics is formally applied in engineering. These strategies should include concrete actions that foster attitudes of critical thinking and a better ability to argue, interpret, and make judgments independently, ultimately acquiring a set of skills, especially in problem-solving. The results show that an engineering student as a critical thinker must have a critical attitude, which is evidenced through dispositions, habits, and character traits, which, when stimulated through mathematics, would contribute to their professional formation.

Validation of the modified Témez rational model in the watersheds of Norte de Santander, Colombia
...
calixto, nelson javier | 2021-06-11

Physics includes the study and investigation of the phases that make up the hydrological cycle, including the estimation of flow rates in river basins, most of which are not instrumented, i.e., they lack historical records of circulating flows. For this situation, the application of hydrological models can allow flow estimates to be made. In the Department of Norte de Santander, Colombia, some watersheds do not have instrumentation for flow measurement or hydrological modeling methodologies appropriate to the site. Therefore, methods such as the modified rational model of Teméz are used, even without knowing the relevance of its applicability to the site conditions. Consequently, for the present research, the Teméz model was validated in watersheds of the Norte de Santander Department to estimate the values of extreme flows with a return period of 100 years. In this sense, 11 watersheds were selected, which contained historical rainfall data greater than 20 years and a drainage network of fewer than 1000 Km2. It was found that the Teméz model overestimates the real flows of the 11 hydrological basins, where the climatological parameters used in the application of the Fhrüling factor and its statistical verification using multivariate regression did not achieve an acceptable correlation.
