Abstract Three experiments were done with different particle sizes of corn feed on its zootechnical performance, passing rate and apparent digestibility juvenile tambaqui (Colossoma macropomum). In the first, 200 juveniles used distributed in 20 tanks (220 L), 10 fish per unit (four replicates). The experimental system to record passage time was composed five incubators L. second, 75 55 days (t...

Corn, wheat, and soybean meal (SBM) have been primarily used as feedstuffs in animal feeding programs. However, it is necessary to explore evaluate alternative deal with variable costs the supply of these conventional feedstuffs. This study determined nutrient composition macadamia nut cake (MNC) its effect on growth performance broiler chickens fed at graded levels. A total 180 d-old chicks we...

If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations of creatures, what statement would contain the most information in the fewest words? I believe it is the atomic hypothesis (or the atomic fact, or whatever you wish to call it) that all things are made of atoms—little particles that move around in perpetual motion, at...

Background The prevalence of depressive affect is not well defined in the incident hemodialysis (HD) population. We investigated the prevalence of and associated risk factors and hospitalization rates for depressive affect in incident HD patients. Methods We performed a prospective investigation using the Patient Health Questionnaire 2 (PHQ2) depressive affect assessment. From January to July...

Drosophila, Wnt, FGF, Jak/Stat, Rho, Rac, RhoGEF, Pebble, Naked Cuticle The site for the latest installment of the Fly Meeting (March 7–11) was downtown Philadelphia. The conference offered an illustration of all that is great about the Drosophila field bringing together evolutionary biologists, immunologists and everyone in between. Here I will provide a small sample of several advances from t...

We show that the oscillatory driving of crystal surfaces can induce pattern formation or smoothening. Depending on driving conditions, step bunching and meandering, mound formation, or surface smoothening may be seen in the presence of a kinetic asymmetry at the steps or kinks. We employ a step model to calculate the induced mass flux along misoriented surfaces, which accounts for surface dynam...

background:  a great number of premature neonates do not tolerate sufficient milk during the early neonatal period.   objective: to evaluate the effect of oral erythromycin on enhancement of feeding tolerance in preterm newborns.   methods: sixty preterm neonates intolerant to milk of >75 ml/kg/day during 5 days after the start of feedings, were randomized into a treatment and a control groups....
