The objective of this project was to carry out an analysis of the indoor climate of the greenhouse located in the Valle de Santiago region, Guanajuato. It is a zenith-type greenhouse with two wings with a symmetrical face. An orthogonal mesh was made of 50 nodes (25 nodes for each height) Total Den located in the cultivable area and taking the value at the midpoint of each rectangle considering two heights 0.25m and 1.30m with respect to the ground. Humidity and temperature readings were taken in each of the nodes for three weeks and subsequently a data analysis was made and a comparison with the data collected in the different situations; also the temperature was analyzed with the double sum of Riemann and the rule of the middle point. In conclusion, it was determined that the greenhouse yields heat on warm days, while it receives heat on cold days. This behavior coincides with previous studies; however, it occurs that with the hydroponic method there is a greater growth of the crop.

Currently in the process of teaching-learning of mathematics, a panorama of a science with an abstract nature is glimpsed. In such a way that the acquisition of knowledge is in a mechanized way and the teacher's word is taken as dogma. The problems and equations formulated to the student are formulated under a mathematical conception with strong cohesion towards the nature of the operation to be solved, under a perspective that is irrelevant to the student within the process of assimilation of knowledge, leaving even more the aspect of its application within the context of their daily life and therefore how relevant their learning can become. From this area of opportunity arises the concern of this research project based on the improvement of the teaching-learning process based on the contextualization of scenarios that facilitate the acquisition of knowledge, mathematical critical thinking and the ability to locate the field of application of The same, developing their own methodologies, taking into account the teacher and student expertise, thereby trying to achieve a meaningful teaching-learning process, simpler acquisition and retention for the student and to achieve for the teacher.

This article presents information on the implementation of a customized ERP system. Based on the fact that a company already has a functioning ERP system to which it is intended to add a new module, in order to rescue certain resources, to avoid the generation of repeated data and obtain a more robust and secure system. This software was made under the technology of C #, as programming language and SQL Server, as a database server. establishing efficiency and agility in the payroll generation process.
