Kinetic of water diffusion and color stability of a resin composite as a function of the curing tip distance

The influence of curing tip distance and storage time in the kinetics of water diffusion (water sorption-W SP, solubility-W SB, and net water uptake) and color stability of a composite were evaluated. Composite samples were polymerized at different distances (5, 10, and 15 mm) and compared to a control group (0 mm). After desiccation, the specimens were stored in distilled water to evaluate the water diffusion over a 120-day period. Net water uptake was calculated (sum of WSP and WSB). The color stability after immersion in a grape juice was compared to distilled water. Data were submitted to three-way ANOVA/Tukey's test (α = 5%). The higher distances caused higher net water uptake (p < 0.05). The immersion in the juice caused significantly higher color change as a function of curing tip distance and the time (p < 0.05). The distance of photoactivation and storage time provide the color alteration and increased net water uptake of the resin composite tested.

Magnetic color-flavor-locked stars

Using the solutions of the gap equations of the magnetic-color-flavor-locked (MCFL) phase of paired quark matter in a magnetic field, and taking into consideration the separation between the longitudinal and transverse pressures due to the field-induced breaking of the spatial rotational symmetry, the equation of state (EoS) of the MCFL phase is self-consistently determined. Implications for stellar models of magnetized (self-bound) strange stars and hybrid (MCFL core) stars are discussed.

Efecto del color del sustrato en el comportamiento de fijación del caballito de mar de hocico corto (Hippocampus hippocampus)

El caballito de mar (Hippocampus hippocampus) presenta una fase planctónica durante los primeros días de su vida. Cuando cambia a la fase bentónica ha de fijarse en un sustrato adecuado con su cola prensil. Este estudio, realizando recuentos diarios de la distribución de los caballitos en el acuario, ha obtenido como resultado que no existe una preferencia entre el color rojo y azul del sustrato a la hora de la fijación, no obstante, se observó una adaptación progresiva de los peces al sustrato artificial.The seahorse (Hippocampus hippocampus) presents a planktonic phase during the first days of life. During settlement, it fixes to a suitable substratum using its prehensile tail. This study, through a daily counts of the seahorse distribution in the aquarium, established that juveniles seahorse do not show a preference between the red or blue fixation substrates. However, it was observed a progressive adaptation of the fish to the artificial handmade substratum.

Estudio de la selección por el color del alimento en la tortuga boba Caretta caretta tras la eclosión

The behavior of newborn pups of loggerhead turtles (Caretta caretta) towards a potential food after hatching and before eating food for the first time was studied. There was no significant time trend approach and bite of potentially edible objects based on their color or size. However, a clear trend was observed for those objects that are transparent, white or red, independently the sex of the animal. Furthermore, it was verified that the turtles do not have a biting behavior to feed from first contact with water, but it comes after 3 or 4 days. There is also a learning process that determines the choice of targets of further attacks.
