چکیده
Como a cor é um dos atributos organolépticos que influenciam o uso das madeiras para os diversos fins, objetivo deste trabalho foi caracterizar índices colorimétricos qualificação da madeira juvenil de E. saligna. As avaliadas foram obtidas plantio experimental com sete anos. Foram amostradas três árvores as avaliações. Estas seccionadas em toras, sendo primeira tora (tora base), comprimento 2,0 metros. Para caracterização cor, obtidos corpos prova nas dimensões 150 mm x 50 mm. avaliações feitas apenas cerne. Os parâmetros avaliados utilizando espectrofotômetro, valores luminosidade (L*), coordenadas cromáticas faixas verde vermelho (a*) e amarelo azul (b*), saturação cores (C*) ângulo matiz/tinta (h*). apresentaram seguintes médios coloriméricos: Luminosidade (L*) = 70,07; a* 8,89; b* 18,52; 20,56; tinta (h*) 64,30º. A saligna pode ser caracterizada como possuindo coloração rosa-acinzentada. Tal observação responsável pela indicação múltiplos usos dessas peças sólidas.

متن کاملRooting depth explains [CO2] x drought interaction in Eucalyptus saligna.
Elevated atmospheric [CO(2)] (eC(a)) often decreases stomatal conductance, which may delay the start of drought, as well as alleviate the effect of dry soil on plant water use and carbon uptake. We studied the interaction between drought and eC(a) in a whole-tree chamber experiment with Eucalyptus saligna. Trees were grown for 18 months in their C(a) treatments before a 4-month dry-down. Trees ...

This paper presents a mechanism, denoted Neural-PIM, for proactive index management based on the use of artificial neural networks. Neural-PIM is DBMS-independent, runs continuously and with no DBA intervention. Additionally, Neural-PIM is based on a four steps approach: (1) monitoring the workload submitted to DBMS, (2) identifying a set of time consuming queries and discovery the more appropr...
