Desempenho motor. Um estudo normativo e criterial em crianças da Região Autónom...
Afonso, G.H.; Freitas, D.L.; Carmo, José M.; Lefevre, J.A.; Almeida, M.J.; Lopes, Vítor P.; Neves, A.C.; Rodrigues, A.J.; Antunes, A.M.; Esteves, C.M.O objectivo central do presente estudo foi construir valores de referência para os ‘skills’ locomotores e de controlo dos objectos em crianças da Região Autónoma da Madeira, Portugal. A amostra envolveu 853 sujeitos, 426 rapazes e 427 raparigas, que participaram na pesquisa ‘Crescer com Saúde na Região Autónoma da Madeira’. Os ‘skills’ motores fundamentais foram avaliados através do ‘Test of Gross Motor Develop...
The effects of geometry and operational conditions on gas holdup, liquid circul...
Gouveia,E.R.; Hokka,C.O.; Badino-Jr,A.C.In airlift reactors transport phenomena are achieved by pneumatic agitation and circulation occurs in a defined cyclic pattern through a loop. In the present work, the effect of geometrical relations on gas holdup and liquid velocity, and consequently on the gas-liquid mass transfer coefficient, was studied in a 6-liter airlift bioreactor with A D/A R = 0.63; A D, downcomer cross-sectional area, and A R, riser ...
Phenomenological model of the clavulanic acid production process utilizing Stre...
Baptista-Neto,A.; Gouveia,E.R.; Badino-Jr,A.C.; Hokka,C.O.The kinetics of clavulanic acid production process by Streptomyces clavuligerus NRRL 3585 was studied. Experiments were carried out in a 4 liters bioreactor, utilizing 2 complex media containing glycerol as the carbon and energy source, and peptone or Samprosoy 90NB (soybean protein) as nitrogen source. Temperature was kept at 28°C and the dissolved oxygen was controlled automatically at 40 % saturation value. ...
Studies on the rheology and oxygen mass transfer in the clavulanic acid product...
Gouveia,E. R.; Baptista-Neto,A.; Hokka,C.O.; Badino Jr.,A.C.In the present work rheological characteristics and volumetric oxygen transfer coefficient (kLa) were investigated during batch cultivations of Streptomyces clavuligerus NRRL 3585 for production of clavulanic acid. The experimental rheological data could be adequately described in terms of the power law model and logistic equation. Significant changes in the rheological parameters consistency index (K) and flow...
