Nickel -based catalysts were prepared by impregnation and subsequent calcination at a concentration of 10 % by weight on the following substrates : clay , Ti02 , Si02 and Al 203 . These were reduced in a stream of 20 % hydrogen / nitrogen at a temperature of 350 ° C for 2 hours and were characterized by X-ray diffraction with activity measurements determined that the different supports affects performance . The increasing order of performance of the catalysts with different supports in oil hydrogenation process is as follows: clay > Ti02 > at 20 3> Si02 . Activity results show that the clay has a good performance in the hydrogenation process reaching iodine decrease of sunflower oil from 150 076 to the value of 56.77 to a temperature of 280 ° C

The psychoeducational intellectual work of Lev Vygotsky (1896-1943) provides a theoretical and sociohistorical meaning that allows you to see from a contextualized perspective the higher forms of self- regulation, conscious control and forms of self-governance. This contribution to the theory of the psychology of education is clearly consistent with the conclusions of the interaction approaches that have been developed by the sociology of the Chicago School (George Mead, 1863-1931), proposing the concept of “Symbolic Interactionism” (Herbert Blumer, 1900-1987), to explain the essentially social nature of the person and his actions, which were consolidated in the field of criminology. From the recognition of the pedagogical-educational purpose that is assigned to the process and juvenile criminal sanction, the present essay aims to use the socio- historical theoretical (Vygotsky) and ...

This article comprehensively reviews the implementation and impacts of Lean Manufacturing in the plastics industry, with the aim of synthesizing and evaluating how the adoption of these methodologies has contributed to improving efficiency, reducing costs and optimizing production processes. Using a systematic review methodology, 97 relevant articles were selected. The main results of the review indicate that Lean not only improves operational efficiency and reduces waste significantly, but also encourages the integration of advanced technologies such as Industry 4.0. In addition, a strong focus on sustainability is observed, with Lean facilitating practices that support environmental conservation and carbon footprint reduction. In conclusion, while Lean Manufacturing has proven to be an effective tool for improving operations, its effective implementation requires tailored approaches th...

Ultrasound is used for the non-destructive testing of materials. It is applied to know the inner of a material or components when processing the trajectory of the propagation of sound waves. It is know that propagation of waves inside the piece depends on the discotinuities of the material examined, which allows to evaluate the discontinuity about its form, size, direction, since these offer a resistance known as acoustic impedance. When knowing the propagation of the sound waves, its speed and therefore the property of materials are determined.

The research results obtained on the effect that occurs on the properties of the synthesis gas obtained as a result of a biomass downdraft gasification process is presents in this paper, working with a cogeneration system internal to the reactor. A study of the previous related works was carried out, from which the dependent and independent variables necessary to evaluate the final quality of the process in the presence and absence of cogeneration were determined. For this, an experimental statistical design of four levels of type 4n was implemented, which allowed the performance of a comparative statistical analysis of the working states of the gasifier. On the other hand, an energy and exergy analysis of both states is presented where the potential of the gasification process to reuse thermal energy can be verified by incorporating a cogeneration system.

Expert opinion is a technique used in different areas of scientific research, which, in some way, guarantees its social and methodological validity. This method is also used as an instrument to make long-term predictions, with different types of solutions to obtain a concise answer that is achieved with the help of experts who exchange information, cultures and experiences to provide solutions to the relevant and timely problems that may arise. The purpose of this article is to review the quality literature regarding experts' opinion of different applications. This research resulted in an extensive relationship with the topics of technology, technology foresight, and especially education.

Fluorine is a chemical element, it plays a very important role in the oral cavity, bone formation in the first years of life, and it is a fundamental part in the appearance of enamel crystals. It works in the demineralization and re-mineralization processes that occur in the oral cavity, these are found in different types of food that are consumed every day, their main source of consumption is drinking water, fluorinated supplements, formula milk, toothpaste, Oral gum should be consumed with measure in its application for a good dental brushing since excess fluoride can cause a pathology called dental fluorosis, which is why the supervision of adults is recommended at the time of oral hygiene in children. The objective of this literature review is to sensitize parents and health professionals about application protocols and their appropriate use of fluorine compounds, helping to preven...

The research was carried out in an industrial production and packaging export company of Concholepas concholepas located in the city of Tacna, Peru. Two quality variables that have relevance in the final product were determined, the volume of the container and the percentage proportion of proteins in the unit. After that, the means end analisys diagram was finished, for the variable volume in 452,356 g as average of the process, with upper control limits of 454,514 g and lower limit of 450,198 g. In regard to its range, the central line or average of the range was established at 3.74167 g with an upper control limit of 7.91171 g and a lower limit of 0.0 g. For the proportion of proteins, an average proportion of 15.24% was observed with upper and lower control limits of 16.40% and 14.08. Concerning its range diagram, an average range of 2.0% was found, with an upper control limit of 4.25...

In the field of engineering, the most required mechanisms are those in charge of the transfer of information, between the different components of the equipment or system, as well as the exchange of information between the equipment and the different control or management systems is required, that it is required to know the status of the equipment. These requirements are important to be able to measure the performance of the equipment and we need to have the information, one of the protocols that we have available is the serial communication port, through the RS-232 protocol and with the DB9 serial connector and now the USB, in The present work presents a method to exploit this data that we can export through this port as well as the description of an application made in Labview to connect to the equipment by configuring a virtual port "COM3", from which we can receive the information and...

Worldwide more than 7 billion tons of lignocellulosic biomass will be produced by 2025. In Colombia, these residues are mainly disposed of in rivers and open fields, and only 10% is reused and recycled. Non-centrifugal sugarcane bagasse (SCB) is a residue obtained after sugarcane juice extraction during the manufacturing process of panela and is mostly used as fuel for boilers at sugar mills. Wheat bran (WB) is the main waste from wheat flour production. Nonetheless, the chemical composition of these by-products makes them suitable for use as substrates for hemicellulolytic enzyme production from fungi. Here, a whole process for production in a solid-state fermentation system, recovery, and ultrafiltration process for concentration of xylanases by Penicillium sp. Pn004 is presented. The higher productivity (26.7 ± 1.59 U gds-1 day-1) was reached on the fifth day of fermentation with an ...
