This paper deals with an analytical model of a rigid rotor supported by hydrodynamic journal bearings where the plane separation technique together with the Artificial Neural Network (ANN) is used to predict the location and magnitude of the correction masses…

, Oxidative enzymes are responsible for changes in flavor, texture, color and also in some nutritive properties of several fruits and vegetables processed in industries. The present investigation aimed to study the activity of Peroxidase (E.C. 1.11.1.7) and Polyphenoloxidase (E.C.…

The intention of this work was to evaluate the growth of Pseudomonas aeruginosa (C1 LBPVMA-UFAL) on lubricant oil and verify the production of rhamnolipid biosurfactant. Tests in solid medium containing lubricant oil supplemented with different sources of nitrogen were used…

Hemicellulose consists of non-cellulosic polysaccharides, with xylans and mannans as their main examples. In nature, xylan can be first degraded to xylooligosaccharides and finally to xylose by certain microorganisms. White-rot fungi basidiomycetes Pleurotus sp. BCCB068 and Pleurotus tailandia were used…

This work aimed to produce jellies with the collagen extracted from chicken feet. Jelly samples were prepared with flavors of pineapple (GAB) and white chocolate (GCB). Using a hedonic scale, 30 untrained tasters evaluated sensory acceptance and willingness to consume…

, We investigate how it is possible to obtain different diffusive regimes from the Continuous Time Random Walk (CTRW) approach performing suitable changes for the waiting time and jumping distributions in order to get two or more regimes for the…

This paper concerns the domination numbers (Pk × Pn) for the
complete Pk × Pn grid graph for k = 7; 8; 9 and for all n ≥ 1.
These numbers were previously established [2] , [4] :
Here we…

The essential oil from the bark of Croton cajucara Bentham, popularly known as sacaca or cajuçara, was obtained by hydrodistillation, yielding 1.28% of the former bark mass, and analyzed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry…

, The Dirac equation have been solved for the q-deformed hyperbolic Scarf potential coupled to a Coulomb-like tensor potential under the spin symmetry. The parametric generalization of the Nikiforov-Uvarov method is used to obtain the energy eigenvalues equation and the…

Drying of agricultural products at high temperatures can be simulated by mathematical models, which intend to describe the drying process close to commercial patterns. They are based on simultaneous heat and mass transfer between the product that is losing moisture,…
