El cultivo del amaranto tiene gran impor­tancia histórico-cultural y alimentaria, pues fue utilizado por distintas culturas mesoamericanas como alimento y en rituales relacionados con sus deidades. El amaranto ha estado presente en la región central de México desde el año 5000 a. C.; allí se ubica el estado de Tlaxcala, que se encuentra entre los principales productores de la gramínea, donde el municipio de Natívitas destaca por ser su mayor productor local. Actualmente, la producción de amaranto se encuentra en riesgo debido al incremento del precio de los insumos, a la escasez de mano de obra y a la excesiva intermediación. Esta inves­tigación, desarrollada en 2018, evalúa las posibilidades de la cadena agroalimentaria del amaranto como eje de una propuesta de agroturismo municipal a partir de su revalo­ración cultural y productiva. Los resultados indican que existen condiciones favorables para que el agroturismo genere ingresos complementarios que permitan incrementar la rentabilidad del cultivo. La metodología comprendió recorridos de campo, análisis de la cadena agroalimentaria del amaranto y de la situación turística, y fue complemen­tada por entrevistas a los actores locales.

The today human being is part of the technological and scientific development dominated by information as a both raw material and base of knowledge.The easy and open accesses to information thrust forward the frontiers of development and communication, enlarge the development's paths and generate amazing changes, faster than ever happened. The way that data bases increase its volume becomes the most actual and complex problem.The ability to extract and process the knowledge and the speed of its processing represent unknown and provocative challenges for business profit and the intelligent society success. Their extraction from the informational noise and the ability to react and rapidly communicate are also important to be accurately customized and harmonised with the social elements.This paper demonstrates the usefulness of neuroscience, neuro-technologies and cognitive computing in finding innovative and customized solutions for solving complex problems in business.The conclusion of our study is that, in order to have an advanced and competitive European Union, it is absolutely necessary to develop innovative solutions for Competitive Intelligence that would include the fundamental elements of neuro-technologies and advanced Artificial Intelligence as Cognitive Business profitable keys.

The paper assesses the importance of the models used to determine the efficiency and the environmental impact of the heating products like heating pumps (HP). An appropriate model of evaluation may help identifying the presence of greenhouse gases and reducing their influence. The paper's novelty resides in the way the hidden sides linked to greenhouse gases' presence, are identified, and eliminated. The research methodology considers an environmental model linked both to the Global Emission Model for Integrated Systems on energy efficiency indicators and to the break-even analysis for greenhouse gases. The model gives hints on reducing the high costs to upgrade the living conditions in residential buildings. The results illustrate the environmental and societal impact and the social potential and highlight the technical implications for such operating systems. They incite optimizing the Heat Hybrid Pumps' design within decentralized energy systems to strengthen energy networks' flexibility and the environmental convenience. The research straightens out the understanding of heat pumps mechanisms, delineates the efficiency of their increasing use through the block-chain technology outlining its future potential for people and society's health and benefit.

The electrospun nanosystems containing poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and 1 wt% Fe doped ZnO nanoparticles (NPs) (with the content of dopant in the range of 0–1 wt% Fe) deposited onto polylactic acid (PLA) film were prepared for food packaging application. They were investigated by scanning electron microscopy (SEM), energy dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), antimicrobial analysis, and X-ray photoelectron spectrometry (XPS) techniques. Migration studies conducted in acetic acid 3% (wt/wt) and ethanol 10% (v/v) food simulants as well as by the use of treated ashes with 3% HNO(3) solution reveal that the migration of Zn and Fe falls into the specific limits imposed by the legislation in force. Results indicated that the PLA/PHBV/ZnO:Fex electrospun nanosystems exhibit excellent antibacterial activity against the Pseudomonas aeruginosa (ATCC-27853) due to the generation of a larger amount of perhydroxyl (˙OOH) radicals as assessed using electron paramagnetic resonance (EPR) spectroscopy coupled with a spin trapping method.

Purpose – The present paper substantiates that the concepts of competitive intelligence and academic entrepreneurship are genuinely connected to the modern society and, through their perpetual and versatile evolution, have an important role in moving the development on the right way. Design/methodology/approach – Their evolutive is completed by a comparative analysis as appropriate method to point out similarities and differences and identify the way their application may serve innovation as a tool for those activating in the related domains of education, within our highly dynamic world. Findings – The development of the concepts is meant to link and accelerate the technological and operational innovation to a highly competitive academic environment, business-oriented, as a contribution to its wide potential for profit. Originality/value – The correlation between the two concepts provides an innovative tool able to serve as a platform helping the competitive intelligence, as design and functions, for any academic entrepreneurship business-oriented.
