Objective: To determine the amount of transportation and the centering ability by nickel titanium rotary systems Mtwo and Twisted File, in mesial roots of lower molars using Cone Beam computed tomography. Materials and Methods: Sixty mesial canals of mandibular molars with severe angles of curvature were divided into two groups. After the instrumentation with rotary systems Mtwo and Twisted File, the amount of transportation and centering capacity were evaluated using cone beam computed tomography. Two sections from middle and cervical levels of the canal were recorded. Student t-tests and U by Mann Whitney tests were used for statistical analysis. Results: Less transportation and better centering ability occurred with Twisted File rotary instruments. However, there was no statistically significant difference between the systems (p≤0.05). Canals were transported mostly towards the mesi...

The contagion of Sars-CoV-2 or Covid-19 inside the city of Huan- cayo is growing, with the transport sector being one of the most affected, so it was planned to reduce the rate of contagion among users of these services. This required the use of RFID-NFC technol- ogy in such a way as to prevent direct and indirect contact between passengers and drivers. Technology that is not dependent on the internet, because it was taken into account that, in that city, the technology is not very expanded so, there are places where the internet signal does not arrive. For this reason, the modules created from RFID technology are a good option to be able to slow the advance of the covid-19.

The agroindustry of not centrifugal sugar (NCS) production is the second agricultural sector in Colombia, due to its contribution to the generation of jobs and planted area. Despite its contribution to the national economy, this agroindustry faces a series of technological problems that require the modernization of traditional production processes, such as the transportation of sugar cane from the crop plots to the processing point (trapiche), which continues to be developed using pack animals. The objective of this work was to characterize the transportation process of sugar cane (Saccharum officinarum) to produce NCS through the definition and measurement of logistical indicators for the transportation of agricultural products. The research was carried out during the months of April and October 2021 in five municipalities in the department of Boyacá (Colombia) where NCS production tak...

The current research was carried out with the purpose of improving the efficiency of maintenance, sales and human resources processes in a transportation company. To achieve this goal, a web application was developed integrating the Laravel 10 framework, the PHP 8.2.4 programming language and a MySQL 8.0.34 database. In addition, the Model-View-Controller approach was applied in order to reduce resource consumption and speed up navigation time. On the other hand, the agile SCRUM methodology was chosen to supervise the implementation, which facilitated team development, error correction and timely completion of activities within the estimated time. In addition, an economic feasibility study was carried out, the results of which indicated that the project is considered profitable and profitable. Likewise, software tests were performed in JMeter, yielding results of 6400, 1055 and 500 simul...

The Current of Brazil (CB) system is associated with the movement and generation of eddies associated with the current. And, to establish the main chain system o the Brazilian region, a region of enormous economic, biological and geopolitical importance for Brazil. The amount of current in Brazil is mainly inuenced by local training, bathymetry and baroclinic and barotropic instability. The calculation of the volumetric transport of the Brazil Current (CB) and the Intermediate Contour Current (CCI) at 23 ° S is performed in this work using data from reanalysis of the HYCOM-NCODA model. A historical leak series was analyzed using basic statistics and a wavelet transformation. The results of the wavelet spectrum show a well-marked annual cycle in CB and CCI. As well as the dierent variation patterns between CB and CCI, the latter found greater variability in the spectrum.

Los servicios de transporte ayudan a las personas a trasladarse y a mover bienes de un lado a otro, ya sea por motivos comerciales o de cambio de vivienda. En el Perú, debido al COVID 19 el gobierno estableció medidas para aminorar las consecuencias del virus, lo que dejó a un grupo extenso de personas sin trabajo, afectando al sector transporte cuyo servicio se realiza en su mayoría de forma tradicional “no digitalizado o sistematizado”, de esta forma los diferentes negocios o rubros fueron sufriendo una transformación tecnológica forzosa para poder continuar sobreviviendo en el mercado. El objetivo principal es analizar la viabilidad del desarrollo de un sistema de información haciendo uso de laarquitectura REST para los servicios de transporte en Lima - Perú, teniendo en cuenta que este se aplica principalmente al traslado de personas y bienes. Durante el desarrollo se ana...

This article presents an investment project to maintain, renovate and modernize the Metro STC rolling stock. This research is focused on alleviating public transportation precariousness, poor quality, and inadequacy in the Mexico City Metropolitan Area. The results suggest that the project is feasible in terms of economic and social impact. Socially, the following variables will be reduced: generalized travel and maintenance costs, CO2 emissions, and catastrophic risk. In financial terms, the net present value is positive, and the benefit/cost ratio is greater than 6. This project is of utmost importance in the present context and considering the recent tragic incident on line 12 of the Mexico City subway.

The use of artificial intelligence nowadays has many applications. This paper proposes the use of artificial intelligence based facial recognition using machine learning to identify through Python language, people who are missing, abducted or have committed crimes. The Jetson Nano development platform identifies and sends an alert via SMS text message to the monitoring and information control units for decision making and response. This device is based on the Ubuntu operating system, which can work standalone, is small, and allows easy accessibility in confined spaces. The tool can also predict people’s moods through gestures made on the face with the application of the Viola-Jones algorithm.

The graphene, since 2004, had show some exceptional mechanical, thermal and electronic properties in se- veral configurations such as optical modulators, transistors, gas detectors, electrocromic devices, electrodes, thermal dissipaters and integrated circuits. There is an inconvenient in the atom by atom manipulation for obtain the specific properties for each function in each proposed device. We account between them, the disorder in the graphene structure and the intercalation of impurities in the hexagonal structure and the imperfections of the substrate that incorporate ripples in the graphene structure. Nevertheless, these do not modify the cones of the valence and conduction bands. The Dirac point remains. Other options has been suggested to induce a gap between the K and K′ symmetry points where lay the Dirac points in which converge the two charge carrier cones, electrons and h...
