In Ecuador, the need to introduce electronic money has been seen as a way to lighten the use of cash and renew the current financial system; however, this implementation has not yielded the desired result and instead has caused much more distrust on the part of Ecuadorians regarding the management of funds by the State; that is why this research show the use of a proprietary cryptocurrency as a new means of payment, in the Ecuadorian economy, leaving aside the current banking system and ensuring that any person, regardless of their income, can access this new financial transactional network . In order to adapt this system in the best way and according to the reality of the country, the theory behind the blockchain and, of course, the cryptocurrency has been studied, the legal environment currently in force in Ecuador, and it has been taken as a reference to Latin American countries that have already introduced these new means of payment in their financial system, analyzing their form of implementation, performance characteristics and results obtained in their economy.
在厄瓜多尔,引入电子货币的必要性被视为减少现金使用和更新当前金融体系的一种方式;但是,这种执行没有产生预期的结果,反而使厄瓜多尔人对国家管理资金产生了更多的不信任;这就是为什么这项研究表明,在厄瓜多尔经济中,使用专有加密货币作为一种新的支付手段,抛开当前的银行体系,确保任何人,无论其收入如何,都可以访问这种新的金融交易网络。为了适应这个系统最好的方法根据国家的现实,区块链背后的理论,当然,研究了cryptocurrency,当前法律环境在厄瓜多尔,它被作为参考的拉美国家已经提出了这些新的支付手段的金融体系,分析它们的形式实现,性能特点,在他们的经济结果。

It presents the results of the microstructural and morphological characterization of a natural Zeolite from the province of Chiriqui, Panama. By X-ray diffraction and Rietveld refinement, the presence of Zeolite Natural Analcima is determined, but with other related minerals, from the point of view of their geological formation, such as: Albite, Diopside and Sanidine mainly. The use of the Fourier Transform Infrared Spectroscopy (FTIR) technique confirms the presence of the Analcima. Combining thermal treatments to the Zeolite and studying the variation of its FTIR spectra, it is inferred that Analcima (and its other constituents) is stable up to 600 °C, since its absorption spectrum does not change significantly, while at higher temperatures absorption bands related crystalline water bonds, progressively decrease up to 1000 °C, where they disappear. The evaluation of the Scanning Electron Microscopy Analcime reveals a mixed morphology, consisting of structures in the form of columns, sheets and polygonal particles, as well as cavities of approximately 5 micrometers in diameter. A particular detail is that with the heat treatment of the Zeolite up to 1000 ° C, the morphology does not change significantly, which suggests the microstructural stability of the Zeolite.
本文介绍了一种来自巴拿马奇里基省的天然沸石的微观结构和形态表征结果。通过x射线衍射和Rietveld精化,确定了沸石天然Analcima的存在,但与其他相关矿物,从其地质构造的角度来看,主要有:钠长石、透辉石和Sanidine。利用傅里叶变换红外光谱(FTIR)技术证实了Analcima的存在。结合沸石的热处理,研究其FTIR光谱的变化,可以推断,Analcima(及其其他成分)在600℃以下是稳定的,因为它的吸收光谱没有明显的变化,而在更高的温度下,与结晶水键相关的吸收带逐渐减少,直到1000℃,它们消失。扫描电镜分析显示了混合形态,包括柱状、片状和多边形颗粒的结构,以及直径约5微米的空腔。一个特别的细节是,当沸石热处理到1000℃时,形貌没有明显变化,这表明沸石的微观结构是稳定的。

One of the most important parameters to define the performance of the steelmaking ladle furnace is the mixing time. The most popular method to determine the mixing time is through an immersed probe to measure changes in conductivity or pH in a single point. An alternative method to measure mixing time is through the experimental technique called Planar Laser-Induced Fluorescence (PLIF). This technique measures concentrations changes of a fluorescent tracer in a whole plane of the system in a non-intrusive way and it has not been reported before in the literature to measure mixing times in these systems. In this work, details on the use of PLIF in physical models of ladle furnaces are studied, such as the effect of the model scale and the effect of the kind of water employed to do the measurements.
决定炼钢钢包炉性能的最重要参数之一是搅拌时间。确定混合时间的最常用方法是通过浸入式探针测量单点的电导率或pH值的变化。测量混合时间的另一种方法是通过称为平面激光诱导荧光(PLIF)的实验技术。该技术以非侵入的方式测量荧光示踪剂在整个系统平面上的浓度变化,并且在文献中尚未报道过测量这些系统中的混合时间。在这项工作中,详细研究了PLIF在钢包炉物理模型中的应用,如模型比例的影响和用于测量的水的种类的影响。

This paper aims to determine the contribution of biotechnology to the graduate index in Chemical Engineering at the National University of Engineering and to analyze whether the number of subjects related to biotechnology in the current program of the Chemical Engineer, is sufficient in relation to the number of graduates obtained as an indirect measure of the demands of the student sector and the community of potential employers, considering that in most cases theses are chosen by students in relation to problems in the productive sector. For the realization of this work it was first defined a period of study between 1990 and 2018, gathering information on these carried out in that period, to finally determine in which areas of biotechnology these theses were being carried out and thus determine whether the career program was meeting the students' knowledge demands for the performance of these jobs. The results showed that, out of 322 thesis studies carried out, 59 of these have been on topics related to biotechnology (18.32 %) and have been carried out in areas of industrial biotechnology, environmental and bioengineering. This work showed the urgent need to make changes to the curriculum that will allow to equip the graduates with the biological tools they need to fulfill the expressed in the profile of the graduate of Chemical Engineering.

Pub Date : 2019-10-01 DOI: 10.1109/IESTEC46403.2019.00018
Ernesto Patricio Feijoo Calle, Cristian Andrés Flores Vera, B. Guevara
In this work the concept of "Granulometric Area" is introduced, which allows to establish a relationship between the granulometric curves and the compressive strength of the rock. After taking a series of rock samples, preparing them and executing crushing processes and evaluating the compressive strength of said materials, a relationship between these two parameters can be established and thus avoid permanently sending samples to the laboratory, allowing a significant savings in time and money. This relationship is presented in a graphic way, and easy to interpret in each study area, establishing the parameters for the identification of the rock treated and studied.
在这项工作中,引入了“颗粒面积”的概念,可以建立颗粒曲线与岩石抗压强度之间的关系。在采集一系列岩石样品,准备它们并执行破碎过程并评估所述材料的抗压强度之后,可以建立这两个参数之间的关系,从而避免将样品永久发送到实验室,从而节省大量的时间和金钱。这种关系以图形的方式呈现,并且在每个研究区域易于解释,为处理和研究的岩石的识别建立了参数。

Currently the function of collection of solid household waste presents considerable drawbacks, due to the deterioration of the state of the roads and the poor development of the Land Management Plan in the city of Villavicencio, especially in the neighborhoods of La Ceiba, Cedritos, La Desmotadora and Seis de Abril, where it is difficult for the collector vehicle to pass, causing a considerable increase in exercise time and dissatisfaction among the inhabitants of the sector. A modification was proposed in the micro route of collection that allowed to optimize the time of the activities making use of strategic points that have containers, where all the solid residues must be deposited, diminishing the distance covered by the vehicle. As a result of this optimization, of 8.86% of the costs reflected in $ 27,603,330 pesos per year.
目前,由于比亚维森西奥市的道路状况恶化和土地管理计划的发展不佳,特别是在La Ceiba、Cedritos、La Desmotadora和Seis de Abril等社区,收集固体家庭废物的功能存在相当大的缺陷,收集车辆难以通过,导致该地区居民的运动时间大大增加和不满。在收集的微路线上提出了一个修改,允许优化活动的时间,利用具有容器的战略点,所有固体残留物必须存放在那里,减少车辆覆盖的距离。由于这一优化,8.86%的成本反映在每年$ 27,603,330比索。

Research Mappings: Service Supply Chain versus Servitization 研究映射:服务供应链与服务化
Pub Date : 2019-10-01 DOI: 10.1109/IESTEC46403.2019.00077

Panama is considered as a service country, in which the Panama Canal contributes with more than $1.5 million per year to the state. Known as a logistic hub, Panama's economy depends on service industries. This happens in most of the countries around the world, the service sector represents more than the 50% of the GDP, increasing the importance of an efficient supply chain mangament for service industries. However, to adapt the supply chain management to service companies it most be understanded all the facts around services and the possibility of adapting an existing supply chain model. On the other hand, Servitization is a term referring to the integration of services to a manufacturing company which increased the importance of managing services. This strategy implies changes in the supply chain of manufacturing companies that can be used as a foundation for the service supply chain. Having two different terms that converge in the servitized supply chain, leads the research to the comparison in a statistically way of "servitization" and "service supply chain". The comparison of both topics is done with a bibliometric analysis, using maps done with the Vosviewer software. The bibliometric maps are based on the results of a systematic search, obtaining 211 articles for servitization and 72 for the service supply chain.

巴拿马被认为是一个服务型国家,巴拿马运河每年为国家贡献150多万美元。巴拿马被称为物流中心,其经济依赖于服务业。这种情况发生在世界上大多数国家,服务业占GDP的50%以上,这增加了有效的供应链管理对服务业的重要性。然而,要使供应链管理适应服务公司,最重要的是要了解围绕服务的所有事实以及适应现有供应链模型的可能性。另一方面,服务化是一个术语,指的是将服务集成到制造公司,这增加了管理服务的重要性。该策略意味着制造企业供应链中的变化,这些变化可以用作服务供应链的基础。服务化供应链中有两个不同的术语汇聚在一起,导致研究以统计的方式对“服务化”和“服务供应链”进行比较。这两个主题的比较是通过文献计量分析完成的,使用Vosviewer软件绘制的地图。文献计量图是基于系统检索的结果,获得211篇服务化文章和72篇服务供应链文章。本文最后对所得结果进行了讨论。
{"title":"Research Mappings: Service Supply Chain versus Servitization","authors":"Milena Gómez-Cedeño, D. Ng","doi":"10.1109/IESTEC46403.2019.00077","DOIUrl":"https://doi.org/10.1109/IESTEC46403.2019.00077","url":null,"abstract":"Panama is considered as a service country, in which the Panama Canal contributes with more than $1.5 million per year to the state. Known as a logistic hub, Panama's economy depends on service industries. This happens in most of the countries around the world, the service sector represents more than the 50% of the GDP, increasing the importance of an efficient supply chain mangament for service industries. However, to adapt the supply chain management to service companies it most be understanded all the facts around services and the possibility of adapting an existing supply chain model. On the other hand, Servitization is a term referring to the integration of services to a manufacturing company which increased the importance of managing services. This strategy implies changes in the supply chain of manufacturing companies that can be used as a foundation for the service supply chain. Having two different terms that converge in the servitized supply chain, leads the research to the comparison in a statistically way of \"servitization\" and \"service supply chain\". The comparison of both topics is done with a bibliometric analysis, using maps done with the Vosviewer software. The bibliometric maps are based on the results of a systematic search, obtaining 211 articles for servitization and 72 for the service supply chain.
