This experimental work was performed to measure to what degree will strengthen the incorporation of digital self-instructíonal materials in teaching-learning process, in Professional Academic 5choo1 of Agro-industrial Engineering in the National University of San Martin-Tarapoto, using as a sample two groups of 27 and 17 student's; and as instruments: The Training mixed mode, Syllabus and digital self instruction manual; and also the Test for evaluating and improving the teaching learning process. The results confirm the research hypothesis since it has been shown that the incorporation of Digital Quality Auto-instructiva Materials significantly strengthened the teaching-learning process at the National University of San Martín-Tara.poto, 'Since executing statistical tests, it was observad that the average the post test experimental group significantly exceeded to the post test control...

Coffee is a product widely consumed worldwide, because it has a stimulating and energizing power. In addition, the drying process is an essential factor that influences the final quality of the product, in this sense, the objective of this article was to estimate the humidity of parchment coffee by using an automated solar dryer, using mathematical models. The models used were multiple linear regression and nonlinear regression, the same as those determined with the R and Curve Expert Professional software respectively. The data needed to estimate these models, were collected in the field for five days, which consisted of applying the automated solar dryer on the plot of a farmer from the town center of Las Naranjas, Jaén, Cajamarca, Peru whose variety was Catimor. Five models were determined: A multiple linear regression model and four non-linear models with a correlation coefficient &...
