Studio "Salute degli anziani del territorio" – (SAT), efficacia dell'attività fisica adattata (APA – salute in movimento), nel miglioramento delle performance motorie e delle competenze cognitive in risposta alla cronicità

I risultati ottenuti dimostrano come un programma di attivit\ue0 motoria in dual-task combinato con training cognitivo adattato alle abilit\ue0 dei partecipanti possa contribuire a preservare la funzionalit\ue0 ecologica e le competenze cognitive che concorrono ad una migliore autonomia e conseguente qualit\ue0 della vita dell\u2019anziano. Il risultato pi\uf9 innovativo dello studio \ue8 stato il miglioramento delle capacit\ue0 cognitive riscontrato dopo il periodo di allenamento, in entrambi i Gruppi, ma con un\u2019evidenza significativa maggiore per il gruppo sperimentale, che evidenzia l\u2019importanza di comprendere, in un programma di APA, esercizi di educazione respiratoria e routine di esercizi motori e cognitivi combinati, con particolare riferimento alla fluidit\ue0 verbale, alla capacit\ue0 attentiva nonch\ue9 le abilit\ue0 prassiche spesso legate a deficit cognitivi nelle ADL. Tutto questo potrebbe avere effetti neuro protettivi che possono aiutare a rallentare il declino cognitivo in et\ue0 avanzata. Risulta quindi importante promuovere iniziative per favorire l\u2019APA tra la popolazione anziana

Extending ontological categorization through a dual process conceptual architecture

In this work we present a hybrid knowledge representation system aiming at extending the representational and reasoning capabilities of classical ontologies by taking into account the theories of typicality in conceptual processing. The system adopts a categorization process inspired to the dual process theories and, from a representational perspective, is equipped with a heterogeneous knowledge base that couples conceptual spaces and ontological formalisms. The system has been experimentally assessed in a conceptual categorization task where common sense linguistic descriptions were given in input, and the corresponding target concepts had to be identified. The results show that the proposed solution substantially improves the representational and reasoning \ue2\u80\u9cconceptual\ue2\u80\u9d capabilities of standard ontology-based systems

Efecto del formulado comercial de Trichoderma harzianum en semillas de trigo

Wheat is one of the most important cereals in the world for human consumption therefore fungal diseases and its control represents a great challenge. This experiment was carried out with the objective of looking for an alternative biological control agent, it was undertaken evaluating the effects of different doses of the commercially formulated Trichoderma harzianum Rifai (1969), fungal base, on quality physiological and sanitary selected wheat seeds. Two different planting methods were employed: in the Blotter test, sowing in seedbed, using a completely random array, applying five treatments with eight repetitions of 50 seeds, reaching a total of 400 seeds, with three different doses of the product (100, 200, 300 mL/100 kg seeds), including the absolute test subject and the chemical composition (Carbendazin + Thiram). The results were subjected to the ANAVA and the Tukey test allowing for a 5 % error margin. The fungal genera identified in the wheat seeds were Rhizopus spp. and Aspergillus flavus, in the control subject, The Rhizopus spp. genus fungi prevailed, while the application of different doses of T. harzianum resulted in a decrease of these colonies. According to the level of control, the three doses of the commercial formula applied were satisfactory, in addition to positively influencing the germination percentage of the seeds in relation to the control and the higher index of growth speed was observed after applying T. harzianum at a 300 mL/100 kg of seed dosage. T. harzianum can be used as a biostimulant in plants with a good antagonistic capability against phytopathogens that cause disease in wheat seeds.El trigo es uno de los cereales de mayor importancia en el mundo para el consumo humano y las enfermedades fúngicas y su control representa un gran desafío. Buscando alternativas de control biológico, este experimento se realizó con el objetivo de evaluar los efectos de diferentes dosis del formulado comercial a base de Trichoderma harzianum Rifai (1969), sobre la calidad fisiológica y sanitaria de las semillas. Se utilizó dos métodos de siembra: en Blotter test y siembra en almácigo, empleándose un diseño completamente al azar, compuesto con cinco tratamientos y ocho repeticiones de 50 semillas, totalizando 400 semillas, con tres diferentes dosis del producto (100, 200, 300 mL/100 kg de semilla), más el testigo absoluto y el químico (Carbendazin + Thiram). Los resultados fueron sometidos al ANAVA y al test de Tukey al 5 % de error. Los géneros de hongos identificados en las semillas de trigo fueron Rhizopus spp. y Aspergillus flavus, en el testigo prevalecieron hongos del género Rhizopus spp., mientras las aplicaciones de diferentes dosis de T. harzianum permitieron la disminución de sus colonias. Según el nivel de control, fueron satisfactoria las tres dosis del formulado comercial utilizado, además de influenciar positivamente en el porcentaje de germinación de las semillas con relación al testigo y el mayor índice de velocidad de emergencia fue observado con la aplicación de T. harzianum a una dosis de 300 mL/100 kg de semilla. T. harzianum puede ser utilizado como bioestimulantes de las plantas con buena capacidad antagónica contra los fitopatógenos que desarrollan enfermedades en semillas de trigo
