Fluid filtration during oil drilling is a technical anomaly resulting in losses due to inadequate extraction and displacement of oil within the well; currently, there are several filtration controllers, although they are quite expensive. In recent years, cassava starch (Manihot esculetum) has been used for its physicalchemical properties, resulting in a sustainable alternative. Therefore, this research aimed to obtain and evaluate a filtering controller for oil well drilling fluids based on cassava starch. For this purpose, filtrate and rheology control tests were carried out using fermented native cassava starch as treatment. These were 1 Universidad UTE.

This paper provides a numerical assessment of the ductile fracture of the AA6101 and AISI 4340 alloys using the Lemaitre and Gurson models.The simulations were carried out to verify the evolution of the accumulated plastic strain at fracture, assuming the high range of the triaxiality ratio, applying monotonic tensile loads on smooth and notched cylindrical specimens. The numerical strategy was structured for the Lemaitre and Gurson models, from establishing a non-linear system of equations using an implicit integration algorithm and solving the non-linear equation system using the Newton-Raphson method. When assessing the numerical and experimental results, it was observed that the cumulative plastic strain at the fracture decreases with the increasing levels of the triaxiality ratio for both alloys and models. On the one hand, the Lemaitre model was more optimistic than the experimental results. On the other hand, Gurson’s model proved to be more conservative in its prediction of ductile fracture. Regarding determining the fracture onset, in general, both models showed good predictive capacity. However, the numerical results for the aluminum alloy presented more in agreement with experimental data than for the AISI 4340 alloy. In the end, assuming the determination of the level of displacement at fracture, the Gurson’s model has the best performance. In this sense, for a high level of triaxiality ratio, the Gurson porous material can be recommended to describe the mechanical behavior of the material at fracture.

This paper presents a State Estimation Algorithm for Distribution Networks based on the Unscented Kalman Filter (UKF). Instead of nodal voltages, this method uses nodal active and reactive power as state variables in the dynamic model. Different demand forecast algorithms to assist the prediction step were tested and compared. In addition, the algorithm includes the software package OpenDSS as a calculation engine. We used the 13-node IEEE distribution network to test the methodology by simulating several scenarios of measurement generation. These simulations were based on the measured values of a local energy distribution company. The results exposed different performance levels depending on the nature of the scenario and the selected forecast method.

Desde hace varios años el Grupo de Investigación en Solidos Porosos y Calorimetría del Departamento de Química de la Universidad de los Andes (Colombia), ha venido desarrollando una serie de actividades en las cuales han participado distinguidos investigadores a nivel internacional, en áreas como adsorción, catálisis y calorimetría aplicada. Éstas se desarrollaron inicialmente como seminarios y se convirtieron en lo que hace siete años se denominó I jornadas de Adsorción y Materiales porosos que se planificó inicialmente como una actividad nacional y la cual contó con la participación de seis profesores invitados, entre ellos cuatro internacionales. En este sentido se propuso dar continuidad a este evento gracias al apoyo irrestricto del Departamento de Química y la Facultad de Ciencias de la Universidad de los Andes, de esta manera se organizaron el II y III Workshop on Adsorption, Catalysis and Porous Material (II y III WACPM) cuyo objetivo fundamental continuó siendo reunir a profesores e investigadores de prestigio internacional para compartir sus experiencias y conocimientos con los participantes del evento, además crear espacios de colaboración y continuidad con las existentes.En esta ocasión, se realizará el IV WACPM, en colaboración con la Universidad de América, Universidad de la Guajira, Universidad Libre de Barranquilla, Universidad Nacional de Colombia, y Universidad del Rosario para promover el espacio de investigación formativa y un encuentro entre científicos, colegas, amigos y estudiantes.
