This article describes the work carried out to investigate behavior of concrete by adding interlocking steel fibers in different proportions (0%, 1%, 1.5%, 2% and 2.5%) for rigid pavements, said addition was made percentage as an concrete. With f'c 280 kg/cm2 standard concrete, tests were determine its resistance compression 28 days, flexion diametral traction days. It obtained results that optimal test reaching a 350 at 2.5%, best The value tensile 2.5% finally ASTM C944 it result is all...
Ascorbic acid is a beneficial component for health, but it degraded during the thermal pasteurization of food products. The aim this research was to determine influence temperature on degradation ascorbic in peach nectar at 75, 85 and 95 °C, evaluating effect 0, 30, 60, 90 120 minutes. follows first order reaction model with rate constants that vary between 5.5 10.9 x 10-3 min-1. D-Values ranged from 211.28 418.73 min, while Z value 69.4 oC. values free energy inactivation 112.63 117.17...
The aim of this work was to assess the terms associated with mass transfer in lycopene recovery from waste a tomato canning plant. Moringa oleifera Lam oil employed as solvent. An ultrasonic extraction carried out on skin and seeds. operational variables were temperature (skin: 45, 60, 75, 90 ºC; seed: 75 ºC), matrix/solvent ratio (m/v) (1:20, 1:25, 1:30), particle size < 1, 1-2, > 3.15 mm; 2 mm) extract separation method (filtration centrifugation). Kinetic constant, concentration...
The aim of this work was to study the convective drying tomato skin as by-product processing industry and influence operation on lycopene content extracted with Moringa oleifera oil. effect combining air temperatures (40, 55 70 °C) velocities (1, 2 3 m/s) kinetics were studied. Diffusional empirical models fitted experimental data. conditions determined from its extraction in moringa Temperature velocity combination had a significantly (p > 0.05) kinetic. This can promote reduction...
Se compararon tres dietas basadas en ensilaje de yerba estrella formuladas para contener 20, 26 y 32% fibra detergente neutro (FDN) evaluar su efecto sobre el potencial consumo materia seca (MS) producción leche vacas Holstein a media lactancia (110 días). Las se asignaron tratamientos acuerdo con un diseño cuadrados latinos 3 x 3, replicado cuatro veces. Los no tuvieron MS base del porcentaje peso vivo (PV) la vaca; los promedios generales fueron 15.4 kg/vaca/día 3.06% PV, respectivamente....
