We evaluated the hypothesis that an exposure of at least 20 hours per week with reagents during academic practice or research projects of teachers, workers and students of Chemistry and Chemistry Engineering Faculty of San Marcos University, caused an increase in biomarkers of exposure of early effect. The frequency of micronuclei in the oral mucosa was analyzed to check the cytogenetic effect in two populations: Problem Group and Control Group. In each population was taken three groups totaling 85 individuals: teachers (mean age: 56,6 ± 6,48), non-teaching staff (mean age: 48,5 ± 17,5) and students (mean age 25,14 ± 4,99). We used the micronucleus test (Mn) in epithelial cells of the oral mucosa. When comparing the values obtained from DNA damage for each individual and for statistical analysis, ANOVA was applied with a significance value of 95% reliability. Damage was found at the c...

In the development of educational activities, being able to understand and understand the activities carried out is important to be able to have the greatest concentration, many techniques use audio-visual educational material. Taking advantage of this material in the present work a methodology is proposed to be able to use this material using low-cost devices, in order to have a virtual reality system with all the functionalities and with a control where the development of the material that is being displayed can be monitored. as well as being able to manage the material. The methodology proposes the use of virtual reality glasses the size for children, a cell phone, a computer and a wireless network, accompanied by a virtual reality program that can be configured and connected between a computer, this configuration is done using the application “Trinus VR”, which allows us to conne...

Currently with the development of technology, we can find a number of devices with different communication and connectivity technologies, which can be used for different applications. We can find devices that can be connected through wireless networks using protocols such as WIFI, Bluetooth, RF, among others, that allow information to be sent and received. We also find devices that are used to store relevant and important information and that is always available such as RFID. In an analysis to evaluate the strategy in solving problems, we can find different ways to use these devices working individually, the complexity of the solution grows increasing the level of complexity, if you decide to integrate different communication protocols with the intention to have a more robust solution that allows the integration of different technologies. In this paper we present a methodology to be able...

The present study has as main objecuve the search of new materials, among them the porous materials whose diversity of pore diameter confers lO the same specific properties, those that in turn determine a series of applications like adsorbents. catalysts, and shield materials, among others. The investigatíon consists of the synthes1s of macroporous materials by the method Sol-Gel, using reactive of low cost as sodium silicate (silicon source) and includes/understanos the following stages: 1) control of hydrolysis of the inorganic precursors: 2) formatíon oí the rnacrostructure material (hydrothermal synthesis) and 3) elimination of the organic matter by calcinations. The structural characterization and the degree of crystalinidad were made by means of Diffraction of Rays-X (DRX) and Electronic Diffraction of Area Selecta.(DEAS), whereas the morphologic analysis was made through an Ele...
