Heart rates of 46 breast-fed and formula-fed infants were monitored continuously for approximately 18 h at 1 or 4 months of age. Heart rate differed significantly by age (1 month greater than 4 months; p less than 0.001) and feeding mode (breast-fed less than formula-fed; p less than 0.001). Approximately 58% of the variability in heart rate could be attributed to feeding mode, sex, and age. He...

OBJECTIVE To evaluate the effectiveness of the peer counselling (PC) programme on breast-feeding initiation among participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Missouri, and to identify factors that facilitate breast-feeding initiation. DESIGN We used the data from the 2006 Missouri Pregnancy Nutrition Surveillance System, Missouri Live B...

We studied the effects of inorganic turbidity on the efficiency of perch (Perca fluviatilis) feeding on the cladoceran Sida crystallina attached to floating macrophyte leaves together with the effects of the floating leaves on the light environment. We expected feeding efficiency to decrease constantly along an increasing turbidity gradient without an enhancement in moderate turbidity values, a...

The fermentation rate of rumen microorganisms obtained from a sheep fed on hay was determined at different hours after feeding. The highest rate of fermentation was obtained immediately after feeding whereas the lowest rate was always before feeding. The effect of adding glucose, sucrose, and starch alone or in combination with urea, sodium citrate, or succinic acid on the maximal fermentation ...

Laser-based additive manufacturing (LBAM) requires precise control over the metal, ceramic, or carbide powder added to the molten pool. The feeding rate of the powder must be very consistent, and it must respond rapidly to commands to change the feeding rate. LBAM also requires feeding rates as low as one gram per minute. Currently, commercially available powder feeders are optimized for such t...

We investigated one causal explanation for geographic variation in clutch size and aggregative feeding of the pipevine swallowtail, Battus philenor. Populations in California lay larger clutches than those in Texas, and larger feeding aggregations grow at an accelerated rate on the California host plant. Using reciprocal transplant experiments with larvae from California and Texas populations, ...

The food responses of Drosophila larvae offer an excellent opportunity to study the genetic and neural regulation of feeding behavior. Compared with fed larvae, hungry larvae are more likely to display aggressive foraging, rapid food intake, compensatory feeding, and stress-resistant food procurement. Behavioral assays have been developed to quantitatively assess particular aspects of the hunge...

We evaluated the effects of membrane surface area (cm2), female density, and container/cage size on feeding response in laboratory-reared Aedes aegypti. Female density did not affect feeding rates at low surface areas, but higher density did significantly increase feeding as surface area increased. Females in large, cloth cages fed less compared to those in large, plastic cups. The rate of feed...

background: the protein hormone granulocyte colony-stimulating factor (gcsf) stimulates the production of white blood cells and plays an important role in medical treatment of cancer patients. methods: an efficient process was developed for heterologous expression of human gcsf in e. coli bl21 (de3). the feeding rate was adjusted to achieve the maximum attainable specific growth rate under crit...
