espanolLa accesibilidad web es aquella caracteristica que permite que cualquier persona sin importar sus condiciones pueda acceder a los contenidos de los sitios web. El uso de validadores automaticos permite realizar un primer analisis acerca del nivel de accesibilidad de un sitio web. Sin embargo, la seleccion de estas herramientas tiende a no ser trivial, debido a las diferencias tecnicas que presenta cada validador. El objetivo de este trabajo fue realizar un analisis comparativo entre validadores automaticos de accesibilidad, buscando establecer criterios de seleccion a la hora de elegir un validador para realizar una evaluacion de accesibilidad. Se propuso una metodologia basada en tres etapas que permitieron seleccionar 14 validadores que fueron analizados bajo diferentes criterios. Ademas, permitio concluir que ninguno de los validadores analizados cumple con todas las caracteristicas, por lo que no seria suficiente seleccionar solo uno para realizar un proceso de evaluacion de accesibilidad. Por lo tanto, este proceso metodologico se constituye como una herramienta de gran utilidad para la seleccion de validadores de accesibilidad.

espanolLa Phytolacca americana es una especie de planta de la familia Phytolaccaceae nativa del Norte de America utilizada como tratamiento autoctono en enfermedades comunes y controversiales como el cancer, debido a sus propiedades analgesicas, antiinflamatorias y antimicoticas. El objeto de este estudio fue caracterizar a nivel fitoquimico los compuestos presentes en las hojas de esta planta y determinar su potencial antifungico. Para ello, se evaluaron tres condiciones de secado: temperatura ambiente (12 ± 2 °C), 22 °C y 40 °C; tecnica de infrarrojo con trasformada de Fourier (FTIR) y espectrofotometria UV/VIS donde se evidencio que las condiciones de secado no influyeron en la estabilidad de los grupos biosinteticos. Ademas, se identificaron metabolitos secundarios mediante screening fitoquimico como flavonoides, saponinas, cumarinas y taninos en extractos etanolicos que se analizaron mediante cromatografia de gases acoplada a espectrometria de masas con bombardeo electronico, en donde se reconocieron acidos esenciales con fines comerciales como el acido oleico. Finalmente, se evaluo el potencial antifungico de los extractos etanolicos con concentraciones de 60 a 300 mg/mL, en cuatro tipos de cepas: F. solani, A. brasiliensis, S. kudriavzevii y C. albicans, los resultados mostraron mayores diametros de inhibicion de 18 y 19 mm contra las cepas F. solani y C. albicans, respectivamente. EnglishPhytolacca americana is a species of the Phytolaccaceae family native to North America. P. americana is used as a folk medicine to treat inflammation, fungal infections, rashes and breast problems; moreover, recent publications support possible anticancer properties. The purpose of this study was to characterize and compare the phytochemical constituents of the leaves of P. americana, and determine their antifungal potential. For this, three temperatures were evaluated to dry the leaves: ambient temperature (12 ± 2 °C), 22 °C and 40 °C, then extracts of the leaves were obtained by ethanol extraction. FTIR and UV/VIS spectroscopy analysis of the extracts shows that the drying temperatures do not affect the stability of the biosynthetic groups. Main secondary metabolites such as flavonoids, saponins, coumarins and tannins were determined by phytochemical screening. Furthermore, extracts were analyzed by means of gas chromatography coupled to mass spectrometry (GC-MS), essential acids such as octadecanoic and some alcohols were identified. Finally, the antifungal potential of ethanolic extracts with concentrations of 60 to 300 mg/mL was evaluated in four types of strains: F. solani, A. brasiliensis, S. kudriavzevii and C. albicans. Results shows inhibition diameters of 18 and 19 mm for F. solani and C. albicans strains respectively.
美洲商陆是商陆科的一种植物,原产于北美,由于其镇痛、抗炎和抗真菌特性,被用作癌症等常见和有争议疾病的自调治疗。这项研究的目的是在植物化学水平上表征这种植物叶子中存在的化合物,并确定其抗真菌潜力。为此,评估了三种干燥条件:室温(12±2°C)、22°C和40°C;傅里叶变换红外技术(FTIR)和UV/VIS分光光度法,其中有证据表明干燥条件不会影响生物合成基团的稳定性。此外,还通过筛选乙醇提取物中的黄酮、皂甙、香豆素和单宁等植物化学物质来鉴定次要代谢物,并通过气相色谱-质谱-电子轰击法进行分析,在其中识别了油酸等商业用途的必需酸。最后,评估了浓度为60至300 mg/ml的乙醇提取物对四种菌株的抗真菌潜力:索拉尼、巴西A、库德里亚夫泽维和C。白色念珠菌,结果显示,对索拉尼和C菌株的抑制直径分别为18和19毫米。美洲商陆是商陆科的一种,原产于北美。P、 美国人被用作治疗炎症、真菌感染、搔痒和乳房问题的民间药物;此外,最近的出版物支持可能的抗癌药物。这项研究的目的是表征和比较美洲黄杨叶的植物化学成分,并确定其抗真菌潜力。为此,评估了三种温度来干燥叶子:环境温度(12±2°C)、22°C和40°C,然后通过乙醇提取获得叶子的提取物。对提取物的FTIR和UV/VIS光谱分析表明,干燥温度不影响生物合成基团的稳定性。通过植物化学筛选确定了黄酮类化合物、皂苷、香豆素和单宁等主要次生代谢产物。此外,通过气相色谱-质谱联用(GC-MS)分析提取物,确定了十八烷酸等基本酸和一些醇。最后,在四种类型的菌株中评估了浓度为60至300 mg/ml的乙醇提取物的抗真菌潜力:F.索拉尼,A.巴西,S.库德里亚夫泽维和C.白色念珠菌。结果显示,索拉尼和白色念珠菌株的抑制直径分别为18和19毫米。

The article presents a bibliographic review on alternatives of low environmental impact for the recycling of expanded polystyrene worldwide, based on the use of natural resources and the environmental impacts associated with them. The environmental impact of each technique was determined through the construction of an Excel matrix where the frequency of use of: (I) primary, secondary or tertiary techniques, (II) natural resources used and (III) environmental compartments affected. Primary sources that address the issue of expanded polystyrene treatment worldwide were consulted. It was found that the best techniques for the recycling of polystyrene are primary and tertiary specifically manual crushing and use of green solvents such as d-limonene and p-cymene, to leave the secondary and tertiary treatments in last positions, agglutination and generation methods of energy respectively.
本文根据自然资源的使用及其对环境的影响,对世界各地用于回收发泡聚苯乙烯的低环境影响替代品进行了文献综述。通过构建Excel矩阵来确定每种技术的环境影响,其中使用频率:(I)一级、二级或三级技术,(II)使用的自然资源和(III)受影响的环境分区。咨询了世界各地处理发泡聚苯乙烯问题的主要来源。研究发现,回收聚苯乙烯的最佳技术是一级和三级,特别是手动破碎和使用绿色溶剂,如d-柠檬烯和p-cymene,使二级和三次处理分别处于最后位置,凝集和能量产生方法。

Braking systems are undoubtedly the most important component for road safety, since it determines the total or partial stop of a vehicle and, therefore, guarantees the physical integrity of passengers. Normally, the front brake discs and the remaining percentage absorb 70% of the kinetic energy produced within a vehicle by the rear brake discs, which tend to have the formof a drum brake. These systems benefit from friction to stop a moving vehicle, under the umbrella of hydraulic pressure that pushes the brake pads against the iron-cast disk. In this document, concepts of famous authors around the world on analysis and evaluation of brake discs are provided, which are carried out using a descriptive methodology and an estimation of the characteristics of the brake disc. The review is carried out in computer assisted design through several existing CAD software in the industry, as the main methodology applied to the development of certain research projects, where different geometric characteristics of the brake discs are considered, as well as problems related to wear and corrosion. This research project has shown that it is vital to incorporate existing computer assisted design software to predict performance, improve components and optimize the functionality of the brake system. In this way, road traffic safety and systems efficiency are achieved, which are a matter of great importance for the industry. It is vital to analyze brake systems through Finite Element Analysis (FEA), with the intention of achieving a broader vision of its performance, since the information collected reveals that the geometric characteristics of the brake and cooling ducts influence the heat dissipation. It depends on the form, the type of material and the application, the heat generated between the pad and the brake. Therefore, the heat is dissipated rapidly according to the analysis performed mathematically by the researchers, which are compared with the made in computer assisted design software.
制动系统无疑是道路安全最重要的组成部分,因为它决定了车辆的完全或部分停车,从而保证了乘客的身体完整性。通常情况下,前制动盘和剩余百分比吸收车辆内由后制动盘产生的动能的70%,后制动盘往往具有鼓式制动器的形式。这些系统受益于摩擦,在液压的保护伞下,将制动片推到铸铁盘上,使行驶中的车辆停止。在本文件中,提供了世界各地著名作者关于制动盘分析和评估的概念,这些概念是使用描述性方法和对制动盘特性的估计进行的。该审查是通过行业中现有的几种CAD软件在计算机辅助设计中进行的,作为某些研究项目开发的主要方法,其中考虑了制动盘的不同几何特征以及与磨损和腐蚀有关的问题。该研究项目表明,结合现有的计算机辅助设计软件来预测制动系统的性能、改进部件和优化功能至关重要。通过这种方式,实现了道路交通安全和系统效率,这对行业来说非常重要。通过有限元分析(FEA)对制动系统进行分析是至关重要的,目的是实现对其性能的更广泛了解,因为收集的信息表明,制动和冷却管道的几何特性会影响散热。它取决于形式、材料类型和应用,以及制动片和制动器之间产生的热量。因此,根据研究人员进行的数学分析,热量会迅速消散,并与计算机辅助设计软件进行了比较。
