Diseño y construcción de una planta piloto para la producción de biodisel de manera continua
This work develops a pilot system for biodiesel production and its future implementation at regional or national level. In this research, the most important parameters in the production and quality of biodiesel were determined preliminarily and they turned out to be the alcohol-oil molar relation and the necessary amount of catalyst. Once these values were obtained, the pilot plant was built and greater scale production and quality test took place. These tests produced satisfactory results concerning power, torque, consumption and polluting emissions, and are very related to the results that have been obtained in other works with biodiesel at national and international level.Este trabajo desarrolla un sistema piloto para producción de biodiesel y su futura implementación a nivel regional y nacional.

CIC-Erosión: herramienta computacional para la predicción del desgate erosivo en líneas de producción y transporte de hidrocarburos
La presencia de daño mecánico por erosión en la pared de la tubería, daño debido al impacto de partículas sólidas, puede afectar gradualmente la integridad de los componentes que conforman los sistemas de producción y transporte de hidrocarburos. La implementación de métodos o modelos para predecir el desgate erosivo es una actividad de interés para la industria del petróleo, debido a que sus resultados son usados para el estudio, valoración y seguimiento de los procesos erosivos, además de ser considerados en el dimensionamiento de las líneas y determinación de velocidades máximas de flujo, con el fin de mitigar y controlar la erosión. En este sentido, considerando la necesidad de mejorar la implementación de modelos, y análisis e interpretación de resultados de erosión, se presenta en este trabajo una metodología de cálculo, estructurada y de carácter selectivo, para predecir el desgaste erosivo en líneas de producción y transporte de hidrocarburos. Para conducir la metodología hasta un estado operativo práctico, se desarrolló una herramienta computacional (CIC-Erosion), usando el lenguaje de programación C#. En la fase de desarrollo y aseguramiento de la funcionalidad operativa de la herramienta se realizaron las siguientes subfases: a) definición de la arquitectura del software; b) codificación de los fundamentos teóricos de la metodología de cálculo y de la interfaz del usuario, y c) diagnóstico de la funcionalidad operativa del software usando datos experimentales de tasa de erosión reportados en la literatura e información de casos de estudio hipotéticos. Finalmente, se evaluó el comportamiento predictivo de la metodología de cálculo de erosión usando información de un caso de estudio asociado a un campo de producción de petróleo crudo ubicado en Colombia.

The implementation of methods or models to monitor and predict erosive wear is an important tool for the oil industry. The results from simulations and prediction models can aid in the calculation and determination of line sizes and maximum flow velocities to control and regulated wall erosion. In this work, we present a structured and selective calculation methodology to improve the implementation of models and the analysis and interpretation of erosion data for the prediction of erosive wear in transport pipelines. A computational tool (CIC-Erosion) written in C# programming language was developed to bring the methodology to a practical operational state. To develop and assure the operational functionality of the CICErosion tool, the following activities were performed: a) definition of software architecture, b) programming of the user interface and theoretical foundations, c) evaluation of the software operational functionality; using experimental erosion rate data reported in the literature and information from hypothetical case studies. Finally, the capacity to predict the behavior of the erosion calculation methodology was assessed using experimental data from case studies identified in the crude oil production of a field located in Colombia. When the predictive capacity of the software was evaluated, a good agreement between results obtained with the erosion calculation methodology and the experimental data was observed. Therefore, the CIC-Erosion computational tool can be considered an efficient and reliable alternative for the prediction of erosive wear in infrastructure used in the hydrocarbon industry
Conductive Cellulose Composites with Low Percolation Threshold for 3D Printed Electronics
We are reporting a 3D printable composite paste having strong thixotropic rheology. The composite has been designed and investigated with highly conductive silver nanowires. The optimized electrical percolation threshold from both simulation and experiment is shown from 0.7 vol. % of silver nanowires which is significantly lower than other composites using conductive nano-materials. Reliable conductivity of 1.19 × 102 S/cm has been achieved from the demonstrated 3D printable composite with 1.9 vol. % loading of silver nanowires. Utilizing the high conductivity of the printable composites, 3D printing of designed battery electrode pastes is demonstrated. Rheology study shows superior printability of the electrode pastes aided by the cellulose\u27s strong thixotropic rheology. The designed anode, electrolyte, and cathode pastes are sequentially printed to form a three-layered lithium battery for the demonstration of a charging profile. This study opens opportunities of 3D printable conductive materials to create printed electronics with the next generation additive manufacturing process

Beliefs and Attitudes of Residents in Queensland, Australia, about Managing Dog and Cat Impacts on Native Wildlife
Many humans have created close relationships with wildlife and companion species. Notwithstanding that companion species were at some point themselves wild, some wild (i.e., feral) and domesticated (owned) dogs and cats now have significant impacts on wildlife. Many strategies exist to control the impact of dogs and cats on wildlife, but the successful implementation of management initiatives is tied to public opinions and the degree of acceptability of these measures. This paper reports the findings of a survey assessing the beliefs of residents in Queensland, Australia, about dog and cat impacts on wildlife, and their attitudes towards various strategies and options for controlling wild (i.e., feral) and domesticated (owned) dogs and cats. The responses of 590 participants were analysed. Our respondents collectively grouped strategies into those that directly cause wild dog and cat deaths and those that allow wild dogs and cats to live a ‘natural’ life, which is a variation on past research where respondents grouped strategies into lethal and non-lethal methods. Community acceptability of strategies that directly cause wild dog and cat deaths (each assessed using five-category Likert scores) was lower amongst females and respondents aged 34 years or less. Gender expectations in most places and cultures still predominately suggest that women are more ‘caring’, supportive of animal welfare, and perhaps cognizant that wild dogs and cats are also sentient creatures and appreciate the problematic tension between controlling wild and companion species. Age-related differences may reflect the changing social values of communities at different points in time. There was high support for regulations that enforce responsible pet ownership but not for the importance of pet-free suburbs, which the majority of respondents considered unimportant. These important variations in beliefs and attitudes require careful management within each community for the success of any program to control wild dogs or cats
