Adhesive and Cohesive Strength in FeB/Fe2B Systems
(2018-05-01)In this work, FeB/Fe2B systems were evaluated by the scratch test. The powder-pack boriding process was performed on the surface of AISI M2 steel. The mechanical parameters, such as yield stress and Young’s modulus of the ... -
Polyestyrene and Low Density Polyethylene Oregano´s Essential Oil Functionalization for Possible Antimicrobial Active Packaging Applications
(2018-09-24)Low density polyethylene (LDPE) and polystyrene (PS) samples were functionalized with oregano´s essential oil (OEO) for possible antimicrobial packing applications. Different concentrations of OEO were used (0.5-1.5 % ... -
Automated detection of parenchymal changes of ischemic stroke in non-contrast computer tomography: A fuzzy approach
(2018-06-05)The detection of ischemic changes is a primary task in the interpretation of brain Computer Tomography (CT) of patients suffering from neurological disorders. Although CT can easily show these lesions, their interpretation ... -
Influence of Sintering Temperature on AlCoCrFeNiMo(Tix, x=0,1) High Entropy Alloys
(2018-08-01)In several reported investigations related to powder metallurgy, the manufacture of consolidated specimens by advanced sintering techniques such as hot pressing and spark plasma sintering is preferred, since denser products ... -
Effect on Microstructure and Nanoindentation of a AlCoFeMoNi High Entropy Alloy
(2018-08-01)In this work, elemental powders supplied by Alfa Aesar with purity higher than 99.5% in weight Al, Co, Fe, Mo and Ni were initially weighed and mixed. The MA was performed in a high-energy ball mill (SPEX-8000M) for 10 h ... -
Chitosan–Starch–Keratin Composites: Improving Thermo-Mechanical and Degradation Properties Through Chemical Modification
(2018-05-01)Chitosan–starch polymers are reinforced with different keratin materials obtained from chicken feather. Keratin materials are treated with sodium hydroxide; the modified surfaces are rougher in comparison with untreated ... -
Synthesis of ag2s quantum dots and their biomedical applications

Analysis of mechanical and electrical imperfect contacts in piezoelectric composites
(2018-10-01)The problem of a heterogeneous piezoelectric composite with mechanical and electrical imperfect contact conditions is studied by means of the asymptotic homogenization method. As an illustrative example, in order to provide ... -
Ergo-environmental variables that affect the job satisfaction of the staff of two institutions of higher education
(2018-10-10)A research on ergonomics related to ergo-environmental factors and its impact on job satisfaction of academic staff of two Mexican universities is presented. A validated questionnaire with .94 reliability is applied in the ... -
Structural model to assess the relationship of manufacturing practices to delivery time in supply chains
(2018-12-10)he literature suggests that companies today evaluate the delivery time of their products/services to improve their performance in supply chains, which has great importance due to the global competition and trends in the ... -
A generalization of multiplication modules
(2019-01-31)We are extended definition of multiplication modules to M-multiplication modules when M is a sigma[M]-module. Then we are extended results to this class of modules, especially in case when M is a semiprime Goldie module. -

Predictive model of burnout and labor satisfaction
(2018-10-10)The purpose of this study was to determine the relationship between burnout syndrome and job satisfaction in full-time professors of a Mexican university. The sample consisted of 230 randomly selected teachers, of whom 139 ... -
On Properties of Torsional Metric Spaces
(2018-08-09)We apply general tensor calculus to arbitrary nonrelativistic classical Lagrangian systems and derive general relationships between the torsion tensor and other quantities associated with the coordinate configuration space, ... -
Heuristic mechanism for drone swarm auto-organization
(2018-02-01)Current technology used for fires are: meteorological stations and satellite image and satellites. This last is a great option, but, from space, the fire detection is until it is large enough to be seen from orbital altitude. ... -
