The paper is one of the most used elements in modern society, despite the fact that its invention dates back to ancient times. The paper is used for different domestic, labor and industrial purposes. Its manufacture is made from cellulose pulp and vegetable fibers, which have had a significant environmental impact in recent years. This work proposes the analysis of the production of paper from the use of residues of the banana plant, which could offer a better use of natural resources and a lower impact on nature. In addition, the natural fiber of bananas is resistant and is easily obtained in Latin American countries such as Ecuador, which has a high production of it. The results found show that it is possible to make paper with fiber from banana residues and that it is possible to commercialize and make good use of resources. Keywords: Organic paper, banana waste, environmental protection. References [1]A.

This article presents an approach to the problem of ceramic types adhesion, applying energy and matter balance to the established control volume (cyclone) with the use of mathematical formulas that are interrelated to develop mathematical calculations and establish a new mathematical model The first results are obtained by operating the energy balance considering the collision of particles, using the principle of conservation of energy, the first law of thermodynamics, in order to obtain information that allows describing the phenomena of thermoplasticity and creep, in the formation of adhesions, from a physicochemical and kinetic point of view, which will serve as the basis for understanding their effect. As a result, an energy value of 660 kJ / mol was obtained, sufficient energy to start the transformation of the solid particles to a state of thermo-flow that allows the adhesion phenomenon to be started.

Education has undergone evolutionary changes necessary to be able to generate the necessary contributions for each era, thus creating spaces for discussion that produce new methodologies and new paradigms for teaching. The case of engineering is very particular in these times, and university education should make its best efforts to offer future engineers the necessary skills to face the challenges of modern industry. In this work a literature review is made to analyze the new educational proposals that will be necessary for the training of the engineer in times of industrial digitization. The results show that an adaptation to the teaching processes is necessary, such that an appropriate engineering training is feasible, which assists and meets the requirements of the industry of the future. Keywords: Educational methodologies, modern industry, teaching processes. References [1]La importancia de las letras, «La historia de la educación,» 2010. [Online].

In this work, a mathematical model is developed for the automatic predisposition of the flow of lime and HRD during the primary steeling process in HEA of the steel mill of Sidor, C.A. Model that was possible through an intelligent dynamic process control system, under a descriptive field research profile; considering a sample of 46 commercial grade steel castings (ASTM A 1018). The system consists of two simulation modules that ensure the ideal thermodynamic condition (steel temperature between 1535 to 1575 ° C, ITHD indicator less than 1,5% and a binary base index of the slag between 2 to 2,6 ) for the protection of refractory material and dephosphorization of steel. Having as a result, a reduction of the Tap To Tap of 7,08%; reduction of lime consumption by 5,28% and an increase in productivity of 7,51%.

The analysis of a research work developed in the company C.V.G CARBONORCA of Venezuela is presented, which has two gas purification plants for the cooking area, designed to purify the gas that comes from the cooking ovens. Each plant is made up of solenoid valves, pneumatic valves, transmitters, process mimic panel and a supervisory system. All these elements are governed by a SIEMENS S5-115U PLC which is in a state of obsolescence, which is why the replacement of these automata by ALLEN BRADLEY ContolLogix automata was designed, in order to guarantee continuity in operations in plant. The research was done with a descriptive design of the field experimental type. A code for each gas treatment plant was obtained in RSLOGIX 5000 v17.00.00 and the update of the database of the supervisory system. The operation of the program was also verified through a simulation of the plant in a supervisory system, the deployment of which was designed for this purpose.

The era of the technological revolution increasingly encourages the development of technologies that facilitate in one way or another people's daily activities, thus generating a great advance in information processing. The purpose of this work is to implement a neural network that allows classifying the emotional states of a person based on the different human gestures. A database is used with information on students from the PUCE-E School of Computer Science and Engineering. Said information are images that express the gestures of the students and with which the comparative analysis with the input data is carried out. The environment in which this work converges proposes that the implementation of this project be carried out under the programming of a multilayer neuralnetwork. Multilayer feeding neural networks possess a number of properties that make them particularly suitable for complex pattern classification problems [8]. Back-Propagation [4], which is a backpropagation algorithm used in the Feedforward neural network, was taken into consideration to solve the classification of emotions.

The analysis of a research work developed in the company C.V.G CARBONORCA of Venezuela is presented, which has two gas purification plants for the cooking area, designed to purify the gas that comes from the cooking ovens. Each plant is made up of solenoid valves, pneumatic valves, transmitters, process mimic panel and a supervisory system. All these elements are governed by a SIEMENS S5-115U PLC which is in a state of obsolescence, which is why the replacement of these automata by ALLEN BRADLEY ContolLogix automata was designed, in order to guarantee continuity in operations in plant. The research was done with a descriptive design of the field experimental type. A code for each gas treatment plant was obtained in RSLOGIX 5000 v17.00.00 and the update of the database of the supervisory system. The operation of the program was also verified through a simulation of the plant in a supervisory system, the deployment of which was designed for this purpose.
