Evaluation of the adaptation of the red worm «Eisenia foetida» to leaching sludge from a sanitary landfill with perspectives for its use in vermicomposting processes.

The adaptation of «Eisenia foetida» to an unconventional medium such as leaching sludge opens the door to its use in vermicomposting processes and to the possibility of solving a very problematic waste management problem. The adaptation of the red worm in leaching sludge from a sanitary landfill was evaluated, for which it was necessary to design an experiment combining: sludge and sawdust in variable proportions as substrates and different masses of worms, they were placed in plastic buckets used as units. experimental. In the first instance, the worms were cultivated in the previously conditioned medium, carrying out a control of the environmental variables to verify the adaptation of the organisms while also controlling physical, chemical and biological parameters to determine the degradability of the sludge in time function. Physical changes could be observed in the experimental units such as: looser consistency of sludge, fading of unpleasant odors and increase in the volume of the samples, clear indicators of transformation of the sludge and evidence of colonization of the worms in the experimental substrates. It was concluded that in those experimental units with higher percentage contents of sludge, a greater number of worms adapted and grew and showed higher values ​​of electrical conductivity indicating the presence of inorganic species as a result of the conversion of the initial organic matter, therefore, Eisenia foetida it was effectively adapted to the leaching sludge and, most importantly, after 60 days the sludge showed signs of efficient composting, which is why it is ensured that vermicomposting as an alternative to treat these residual sludge could be viable.

Prediction of the risk level of failure of higher education students using an artificial neural network model.

The desertion of undergraduate students and high academic failure rates is a problem in Ecuador's higher education institutions. If the failure rate in a subject is high, then the number of students who must retake the subject is also high. Therefore, it limits the available resources and makes the educational institutions' authorities constantly restructure physical spaces and teachers. On the other hand, educational data mining uses machine learning and deep learning techniques to analyze and model educational data to predict students' academic performance. Previous studies propose the use of different models of artificial neural networks to predict academic performance; however, these models focus on using only academic data and some students' sociodemographic data. On the contrary, in the present study, educational, sociodemographic, and economic data are considered, which were gathered through digital surveys and educational systems of a higher education institution, and a multi-layer perceptron network is proposed to predict the risk of failure of a student, which will allow students, teachers and authorities to know the risk of loss in a subject so that the corresponding actions can be taken to lower the failure rate. The proposed model reached an accuracy of approximately 88%, demonstrating good performance. Additionally, we compare the proposed model's performance with a decision tree's performance and a logistic regression model; these models obtained approximately 85% and 82% accuracy, respectively.

Evaluation of the chemical fertility of the soil in an initial productive Theobroma cacao system of the “Hermanos Briones” farm, Portoviejo - Ecuador

Introduction. Soil is the most important natural resource and most of life on earth depends on it, its chemical composition is constantly changing, resulting in countless soils. The use of N, P, K, Ca and Mg fertilizers has become essential in most soils in order to obtain high yields and a good quality in the product, being essential to constantly monitor the soil where the crops are grown. The yields in cacao production depend on the soil and certain environmental factors such as light, temperature and humidity. Flattering yields cannot be achieved when, despite the adequate environment, the services provided by the soil are not adequate (Pinargote, 2010). Objective. To evaluate the chemical fertility of the soil in initial productive system of Theobroma cacao, in the “Hermanos Briones” farm in the Portoviejo canton. Methodology. The research work was carried out in an agricultural batch of an initial 2-year cacao crop of 2.4 ha, the cacao plantation used corresponds to the CCN-51 clone, the soil samplings were carried out at random in a systematic way (zig-zag ), obtaining a composite sample, to carry out the chemical analyzes in the laboratory, given analyzes were carried out prior to planting and 2 years after cultivation. Results. The comparison of the nutritional content of the soil is observed, with respect to organic matter there is an increase as the plantation grows, the development of organic matter is greater. The macronutrients Nitrogen and Potassium show a slight decrease, contrary to Phosphorus, the mesonutrients Calcium, Magnesium and Sulfur are in smaller quantities, the micronutrients Zinc and Copper show an increase, different from Iron and Boron, which after 2 years of seedlings have decreased the concentrations of these elements in the soil, with respect to Manganese the concentration has not changed. Conclusions. According to the results of the sampling, the initial productive system presents nutritional imbalances and deficiencies in nutrient content for its development, which is why fertilization plans are required to guarantee adequate sustainability of the system.
