Formation of Tumor Spheroids by Spontaneous Cellular Aggregation in Incubation: Effect of Agarose as a Compaction Agent
(Springer, 2019-10-01)Tumor spheroids is a 3D culture of cancer cells. This type of cell culture is a great tool for the evaluation of novel nanomedicine systems and in other areas of biomedical engineering. The main advantage over monolayer ... -
Resistencia de la unión eje/cubo mediante un modelo por elementos finitos
(Tecnológico Nacional de México, 2019-11)The present work describes a finite element model of a shaft/hub joint with an interference fit of Ø20H7/s6; which aims to evaluate and analyze the axial strength of the joint according to the surface roughness of the parts ... -
Energy Harvesting from Fingers Motions Using a Wearable System: An Experimental Analysis
(Springer, 2019-10-02)An experimental analysis is presented in order to assess the best conditions for energy harvesting from the movement of the fingers using a glove-shape wearable system. Polyvinylidene Fluoride (PVDF) piezofilms were used ... -
Impact of carbon nanotubes in a CrFeMnNiTi alloy proposed as a potential candidate for stainless-steel substitution
(2019-11-01)In the steel industry, the fabrication of sintered products includes the use of graphite as an alloying element and lubricant. This study explores the idea that a sintered alloy with increased properties can be produced ... -
On the Equivalence between Abstract Dialectical Frameworks and Logic Programs
(2019-09-01)Abstract Dialectical Frameworks (ADFs) are argumentation frameworks where each node is associated with an acceptance condition. This allows us to model different types of dependencies as supports and attacks. Previous ... -
Graphite to Graphene: Green Synthesis Using Opuntia ficus-indica
(2019-03-15)Green synthesis promotes partial or total substitution of chemicals that are potentially harmful to the environment with more friendly ones and is also concerned with decreasing energy consumption. In this study, commercial ... -
