Prolongación ascendente y descendente de campos potenciales en el dominio frecuencial

En el presente trabajo se investigan las posibilidades de uso de la prolongación de campos potenciales en el deminio frecuencial como método de filtrado operando tanto con datos areales como en secciones. Se analizan los errores del método utilizando la FFT: digitalización, aliasing y periodicidad y se señalan las normas básicas para minimizar su influencia en los resultados. Por último se efectúa un análisis comparativo preliminar de los resultados obtenidos al efectuar prolongaciones de campos potenciales en los deminios frecuencial y espacial.In the present paper, the posibilities of using the oontinuation of potential field data in the frequeney demain as a filtering method are investigated. The errors of the FFT method: digitization, aliasing and periodicity are analized and sane rules to minimize its influence on the results are pointed. Finally, a preliminary comparative study between the continuation of potential field data in both frequency and spatial domain is perfomed.Asociación Argentina de Geofísicos y Geodesta

Coffee proteins: Functional food ingredients with molecular effects for sustainable health

There is a growing demand for new alternative protein sources to those of animal origin. Coffee and coffee by-products are potential sources for obtaining alternative plant-based proteins. Their application contributes to their upcycling and to the sustainability of the coffee industry, diversifying and reducing its environmental impact. This chapter presents a current literature review of the potential of green coffee beans and coffee by-products as a nutritious, safe, and sustainable source of proteins for human consumption. Green coffee beans and most of the coffee by-products (cascara, silverskin, and spent coffee grounds [SCGs]) are potential sources of proteins, essential amino acids, and bioactive peptides. In addition, coffee derivatives possess compounds of nutritional interest, such as dietary fiber. Novel ingredients obtained based on coffee proteins would be sustainable and hypoallergenic and suitable for all populations including those with special diets for health (celiac) or ideological (vegans) reasons.Peer reviewe
