The following research is carried out in order to develop a sweeping model that allows efficiencies in the workforce of the Municipality of Orizaba, reducing the time of sweeping the routes and taking advantage of the resources available, facilitating decision-making for the relevant authorities through simulation. The project was carried out in three stages, contemplating the analysis of the initial information, which allowed us to study the scanning process, identifying the activities that are carried out and how they are carried out, the next stage consisted in the construction of the simulation model through SIMIO which allowed observing the behavior of the data collected, finally in the stage 3 that is currently being developed, an alternative is proposed to improve the scanning process, which will be implemented as a pilot test, as well as contributing to the design of a manual that allows standardizing this process.

The objective of this research is to estimate the income elasticity of demand for environmental services of three ecosystems in Mexico. In the three studies of stated preferences about the willingness to pay for an environmental quality improvement project, we used a sample size of 289 observations for the Primas Basalticos ecosystems and 150 for the La Michilía Biosphere Reserve and the Molino de Las Flores National Park. The selection of interviewees was random among visitors. To carry out the estimation, a cluster analysis was carried out to determine the income strata, where the indicator was formulated and calculated in each ecosystem for three income strata (high, medium and low) based on a segmentation of the consumers of recreational services through the two-stage clustering method. In this way, the recreational services of the three ecosystems in both cases behave as a normal good; that is, if the income of the high and middle income consumer increases, the demand for recreational services will increase less than proportionally.
本研究的目的是估计墨西哥三个生态系统对环境服务需求的收入弹性。在三项关于为环境质量改善项目支付意愿的陈述偏好研究中，我们使用了289个观测样本的Primas Basalticos生态系统和150个观测样本的La Michilía生物圈保护区和Molino de Las Flores国家公园。受访者的选择是随机的。为了进行估计，采用聚类分析确定收入阶层，通过两阶段聚类方法对娱乐服务消费者进行细分，在每个生态系统中制定并计算了高、中、低三个收入阶层的指标。这样，在这两种情况下，三个生态系统的娱乐服务都表现为正常商品;也就是说，如果高收入和中等收入消费者的收入增加，娱乐服务需求的增长将低于比例。

The objective of this research was to analyze two applications that use pictograms installed on a mobile device with the Android operating system, through surveys applied to teachers, family members and students with autism spectrum disorder (ASD) to evaluate the criteria of usability, functionality, and accessibility. The Omega coefficient was used to evaluate the reliability of the applied instruments so as not to depend on the number of items, the acceptable value should range between 0.70 and 0.90. The evaluations obtained in each one of the surveys were: for teachers of the Multiple Attention Center (CAM) of Tehuacán 0.707 and for parents 0.705, demonstrating that the reliability of the instrument that was applied is adequate. With the results of this analysis, areas for improvement were detected focused on the development of a new mobile application adapted to the needs of students with ASD from the Tehuacán CAM, and as a contribution of a Mexican development in this segment.

This project allows knowing the degree of degradation of disposable diapers using two different biodegradable agents: Isoptera Termites and Activated Sludge. For this degradation process, used diapers were used that contained liquid waste and in their original complete form, for the degradation control the following physicochemical parameters were evaluated: pH, TDS, CE, Temperature, % of degradation, mass and volume reduction. Being part of a very useful product on the market, diapers become part of the large amount of urban solid waste that is generated by excessive use over the years, becoming one of the most notoriously present wastes along with plastic waste. The search for an alternative to accelerate degradation made it possible to compare the best result to contribute to the improvement of the environment

Data mining techniques allow extracting the hidden knowledge in big data sets generated in any field, particularly in the educational field. With the help of this kind of techniques and specialized tools, it is being carried out an analysis of the EXANI-II data bases of the Aguascalientes State (México) corresponding to the 2013 year, whose main purpose is the identification of the factors that impact negatively the academic performance of senior high students, as well as the definition of strategies to reinforce the weak aspects identified in this performance. The models generated as fundamental part of this study will be validated in a subsequent study by using the data corresponding to the 2014 year, in such a way that the generated models have a high level of confidence at the moment of being used. A preliminary data analysis has suggested using mainly the techniques of classification (decision trees) and clustering (grouping by sector) in this study.

Forage corn is a crop in greatest demand in the Comarca Lagunera. The objective is to obtain the models for the production indicators of forage maize hybrids, which could improve the production systems. The variables evaluated were: leaf area index (IAF), number of leaves and dry matter (DM). The DM model as a function of the IAF was 17.13 grams plant per unit of IAF. For the days after sowing (DDS) a production of 5 grams plant / elapsed day was found. For IAF based on DDS, 0.36 units of IAF were obtained per day and the IAF increased by 0.65 units as a function of the number of leaves. It is concluded that the behavior of the evaluated variables provides results of linear and polynomial regression models, with different levels of reliability, which allow future estimates to be made to choose the hybrids that best adapt to the region.
在Comarca Lagunera，饲料玉米是需求量最大的作物。目的是建立饲料玉米杂交种的生产指标模型，为改进生产系统提供依据。评价变量为:叶面积指数(IAF)、叶片数和干物质(DM)。作为IAF函数的DM模型为17.13 g /单位IAF。对于播种后的天数(DDS)，产量为5克/天。基于DDS的IAF每天可获得0.36个单位的IAF, IAF随叶片数的增加而增加0.65个单位。结果表明，评估变量的行为提供了具有不同可靠性水平的线性和多项式回归模型的结果，这使得未来的估计可以选择最适合该区域的混合模型。

On Earth there are a hundred natural chemical elements, but living beings that inhabit used only twenty. Numerous metals make up this group, many of them essential for agencies to complete their life cycle. However, while some are essential for survival, excess or the presence of others can be toxic or even lethal. The plants have developed specific mechanisms absorb and accumulate nutrients, however, some metals and metalloids are absorbed and accumulate in the plant because they exhibit an electrochemical behavior similar to the required nutrients. Absorption of Copper and Nickel by plants is the first step of entering the food chain, metabolic character due to the ability to accumulate metals in their tissues. The test objective was to know the results of recent research to elucidate the function of copper and nickel in plant nutrition.

This research was throughout 2018-2020, filamentous fungi of agricultural importance were isolated from the Cerro Las Tetillas, located in the municipality of Salvatierra, Guanajuato. The hill was divided into three strata: upper, middle and lower. Two hundred soil samples were taken at depths of 0-15 and 15-30 cm. These were processed in the biology laboratory, belonging to the Higher Technological Institute of Salvatierra. Two isolation techniques were used: direct seeding and serial dilutions, over Petri dishes with potato dextrose agar culture medium and 100 mg of streptomycin to control bacteria. One hundred and thirteen axenic strains corresponding to 16 genera identified from “Cerro Tetillas” were obtained. At the upper stratum, 13 genera were identified, while in the middle and lower strata, nine genera were identified in each one of them. The diversity of soil fungi found in the different strata of the hill may be due to physicochemical characteristics of soil, native vegetation, interaction and abundance of soil fungi species, human disturbance and rain runoff.
这项研究在2018-2020年期间进行，从位于瓜纳华托州萨尔瓦蒂拉市的Cerro Las Tetillas中分离出具有农业重要性的丝状真菌。这座山分为上、中、下三层。在0-15 cm和15-30 cm深度采集了200个土壤样品。这些都是在萨尔瓦多高等技术研究所的生物实验室处理的。采用直接播种和连续稀释两种分离技术，在培养皿上用马铃薯葡萄糖琼脂培养基和100 mg链霉素控制细菌。从“Cerro Tetillas”中鉴定出16属的113株无菌菌株。上层鉴定出13个属，中下层各鉴定出9个属。不同地层土壤真菌的多样性可能与土壤的理化特征、原生植被、土壤真菌种类的相互作用和丰度、人为干扰和雨水径流等因素有关。

The evolution of the SARS-CoV-2 Virus in recent months in the world and especially in Mexico has also created changes in the patient’s treatment and their laboratory studies, as is the case of patients admitted to the CECCS in Salamanca, Guanajuato, in which after months of caring for COVID-19 patients, new relevant laboratory studies were added (Ferritin and D-Dimer), therefore updates were made in statistical analyzes, and day-to-day behavior. The study is based on updating and cleaning the database, taking a sample of more patients with COVID-19, statistical analysis including admission tables, Body Mass Index, Variance, Normalization, relationship between the first day and the last day of patients who died and lived. The main idea of the work is to learn with more detail those laboratories that contain information to study in the future if there is a relationship between any medication supplied with the improvement or aggravation of the patient.
