Cambios de color en diferentes condiciones de tratamiento de aceitunas verdes de la variedad Chalkidiki

Green table olives of Chalkidiki variety, which are subject to enzymatic browning during processing and preservation by the commercial method, were collected in different pickings and in two cultivating years. Then, they were treated with 1.5%, 1.7%, 2% and 2.3% NaOH. During the removal of bitterness, washing, fermentation and preservation the green olives were kept, as much as possible, away from any contact with air. The pH was kept at relatively low values (~4.0), mainly during the preservation of green olives. Besides, the concentration of brine was kept constant during the stage of fermentation and preservation (8-10%). The aforementioned precaution resulted in the protection of the colour of the flesh and of the skin from enzymatic browning to a very satisfactory degree. As for the texture of the fruits, the firmness was well presented.Aceitunas verdes de mesa de la variedad Chalkidiki, sometidas a ennegrecimiento enzimático durante su tratamiento y conservación por métodos comerciales, se recogieron en diferentes cosechas y en dos años distintos. Posteriormente, se trataron con un 1'5%, 17%, 2% y 2'3% de NaOH. Durante la eliminación del amargor, lavado, fermentación y conservación, las aceitunas verdes se guardaron, tanto como fue posible, libre de contacto con el aire. El pH se mantuvo a valores relativamente bajos (~4'0), principalmente durante la conservación de aceitunas verdes. Además, la concentración de salmuera se mantuvo constante durante la etapa de fermentación y conservación (8-10%). La precaución anteriormente señalada tuvo como resultado la protección del color de la pulpa y de la piel del ennegrecimiento enzimático a un nivel muy satisfactorio. En cuanto a la textura del fruto, la firmeza se conservó bien

On Λ-Fractional Derivative and Human Neural Network

Fractional derivatives can express anomalous diffusion in brain tissue. Various brain diseases such as Alzheimer’s disease, multiple sclerosis, and Parkinson’s disease are attributed to the accumulation of proteins in axons. Discrete swellings along the axons cause other neuro diseases. To model the propagation of voltage in axons with all those causes, a fractional cable geometry has been adopted. Although a fractional cable model has already been presented, the non-existence of fractional differential geometry based on the well-known fractional derivatives raises questions. These minute parts of the human neural system are modeled as cables that function with a non-uniform cross-section in the fractional realm based upon the Λ-fractional derivative (Λ-FD). That derivative is considered the unique fractional derivative generating differential geometry. Examples are presented so that fruitful conclusions can be made. The present work is going to help medical and bioengineering scientists in controlling various brain diseases
