Oxidation is the main problem in preserving food products during storage. A relatively novel strategy use of antioxidant-enriched edible films. Antioxidants hinder reactive oxygen species, which mainly affect fats and proteins food. At present, these films have been improved by addition micro- nanoliposomes coated with carbohydrate polymers, are not hazardous for human health can be ingested without risk. The liposomes loaded different antioxidants, their effects observed as a longer storage...
The growing need for skilled personnel within the Federal Electricity Commission (CFE) has highlighted importance of developing innovative and resource-efficient training tools. This project aimed to design construct a prototype electric load simulator using recycled materials address demand supplementary methods. methodology included selecting integrating reused components, followed by rigorous testing validate simulator's functionality under laboratory conditions. project's scope extended...
Worldwide, the shortage of fresh water has increased exponentially due to population growth and contamination available water, especially in tables that provide for general consumption. One main pollutants is arsenic (As), present environment most mining/metallurgical processes, which a major health risk, as carcinogen. In region Matehuala, San Luis Potosi (SLP), Mexico, highly productive mining area, concentrations 138.1 mg/kg have been found soils—6.2 times higher than what allowed...
In this work is presented the complete thermal analysis of polyols by direct methods such as simultaneous thermogravimetric and differential analyzer (TGA-DTA), scanning calorimetry (DSC), modulated DSC (MDSC), supercooling MDSC. The different events in temperature range 113⁻553 K were identified for glycerol (GL), ethylene glycol (EG), propylene (PG). Boiling (TB) decreased GL > EG PG, but increased with heating rate. showed a complex event at 191⁻199 K, glass transition (Tg)...
Liposomes are microstructures containing lipid and aqueous phases employed in the encapsulation delivery of bioactive agents. Quercetin-loaded liposomes (QLLs) were coated with three different polysaccharides then tested as radical scavengers. Lactose (LCQLL), chitosan (CCQLL), inulin (ICQLL) coating materials. Particle size determined by light scattering, showed primary 200 nm for all samples, while a secondary particle 600 was observed CCQLL. Scanning electron microscopy (SEM) evidenced...
This paper presents the design and simulation of an exoskeleton based on kinematics human arm intended to be used in robot-assisted rehabilitation upper limb. The meets kinematic characteristics so that allows movement its full range motion. We co-simulation considering a model limb developed Opensim, Solidworks mechanical structure Matlab construct dynamic model. system motion was simulated Simmechanics using predictive dynamics compute independent joint trajectories obtained by modelling...
This work presents the design of a new breast prosthesis using biomimetic technique for cases complete mastectomy to address problem increasing number women diagnosed with cancer in Mexico who are candidates mastectomy. The designed considers morphology real regarding its internal structure obtain authentic mobility and feel. In order accomplish this, model was obtained 3D CAD coordinate measuring machine (CMM) that can be scalable without losing qualities, which used any type patient;...
This work presents the development of a methodology that, through use coordinate transformation method, identifies ideal modal parameters that should be used during balancing process as well allows eliminating computational modes generated rotor response diagram extraction process. There is currently wide variety methods for structures allow extracting limited parameters, such as: previous knowledge number modes, adjustment or spurious close mode identification problems, and others. However,...
Flow boiling into micro-channels is a good option of cooling solutions for electronic devices. Numerical simulations allow designing correctly before manufacturing. In this paper, the results steady-state one-dimensional simulation are presented single horizontal circular 1-mm tube. Through refrigerant flows, two regions distinguished: subcooled liquid flow and two-phase flow. Typical equations correlations have been used flow; while one theoretical model has The here those by using...
The use of electric vehicles and their various configurations is seen as a major alternative in efforts towards reducing pollutant emissions from motor that continue to fossil fuels. Electric transport technology presents more efficient means energy conversion vehicles: (EV), hybrid (VH), (HEV) vehicles. For example, the storage system latter can be made up ultracapacitors (UCs), batteries (Bs), fuel cells. This work focuses on HEVs powered by ultracapacitors. In particular, multiple...
The rheological characterization of fluids using a rheometer is an essential task in food processing, materials, healthcare or even industrial engineering; some cases, the high cost and issues related to possibility developing both electrorheological magnetorheological tests same instrument have be overcome. With that mind, this study designed constructed low-cost rotational with capacity adapt electro- magneto-rheological tests. design team used method continuous improvement through Quality...
In Mexico the development of remote laboratories is incipient, in 2020 National Council Humanities, Sciences, and Technologies (CONAHCYT) created a network virtual with nine its public research centers order to create space that enables experimental activities distance modality. However, access limited only members, platforms are still under development. With this motivation, article presents multi-institutional project for design, development, implementation pico-hydraulic system...
Gyroscopic systems and their properties have been extensively studied as Angular Momentum Devices (AMD), Control Moment Gyros (CMG) or Gyroscopes for various applications such structure control, stability energy storage. However, most of the works that done are theoretical do not present experimental implementation. In this work we performed an study a gyroscope beam system (gyroelastic beam) focused on deflection cantilever beams control flexural stresses. We first used simple two-degree...
This work presents an analytical and numerical methodology that allows determining stress distribution during the functioning of a screw conveyor utilized for conveying granular material. Different operating conditions were studied analytically numerically. Initially, reactions generated when mechanism was fully braced with four supports along longitudinal axis shaft estimated. In addition, system analyzed typical fault in one central supports. The faults occur primarily due to empirical...
