Nutrient requirements increase during periods of growth and development such as pregnancy and lactation. In response, many clinicians recommend dietary supplements during these important periods of the life cycle. Although there exist some recommendations concerning the need for a limited number of nutrients in supplemental form (eg, iron, folic acid, and iodine), there is a relative paucity of...

Shed dinosaur teeth are commonly collected microvertebrate remains that have been used for interpretations of dinosaur feeding behaviors, paleoecology, and population studies. However, such interpretations may be biased by taphonomic processes such as fluvial sorting influenced by tooth shape: shed teeth, removed from the skull during life, and teeth possessing roots, removed from the skull aft...

We examined the effect of seed dispersal by Purplish Jays (Cyanocorax cyanomelas; pulp consumers) and the Chestnut-eared Araçari (Pteroglossus castanotis; "legitimate" seed dispersers) on population growth of the small tree Guettarda viburnoides (Rubiaceae) in northeastern Bolivian savannas. Because each bird species differs with respect to feeding and post-feeding behavior, we hypothesized tha...

16S ribosomal DNA terminal restriction fragment patterns from rat fecal samples were analyzed to track the dynamics of Lactobacillus acidophilus NCFM and discern bacterial populations that changed during feeding with NCFM. Lactobacillus johnsonii and Ruminococcus flavefaciens were tentatively identified as such bacterial populations. The presence of L. johnsonii was confirmed by isolation from ...

Title: INDUCIBLE PLANT RESPONSES LINKING ABOVEAND BELOW-GROUND HERBIVORY: ECOLOGICAL SIGNIFICANCE AND UNDERLYING MECHANISMS Ian Kaplan, Doctor of Philosophy, 2007 Directed By: Professor Robert F. Denno, Department of Entomology Aboveand below-ground organisms can indirectly affect one another via several recently-described mechanisms, one such mechanism being herbivore-induced plant responses. ...

The structure and dynamics of food webs are largely dependent upon interactions among consumers and their resources. However, interspecific interactions such as intraguild predation and interference competition can also play a significant role in the stability of communities. The role of antagonistic/synergistic interactions among predators has been largely ignored in food web theory. These mec...

Flexible Multibody System Dynamics (FMSD) is a simulation technique that can be used to study the behavior of the mechanical systems that consists of one or more deformable bodies. A deformable body can be modeled using a number of approaches while the floating frame of reference formulation is a widely used approach. In that approach, flexibility within Multibody System Dynamics (MSD) is descr...

This study seeks to investigate the effect of restricted feeding regimes at different rate on growth performance of Clarias gariepinus using static and flow through system. Fingerlings were divided into six batches for each systems with the first and second batch fed at 5% body weight (BW) every day and every other day respectively, the third and fourth batch were fed 10% BW every day and every...

Experimental data were obtained on the effect of feeding a phytonutrient based Hungarian sainfoin biochemical, hematological parameters blood, natural resistance and dynamics live weight heifers. As result sainfoin, blood heifers experimental groups higher than those control group. There was also better development compared to

BACKGROUND Despite the nutritional, physiological and emotional benefits of breastfeeding, HIV-positive mothers cannot practise exclusive breastfeeding for six months because of a range of influences on their feeding choice - thereby creating a caveat for morbidity in infants. AIM This study explored factors influencing the infant feeding choice of HIV-positive mothers at a peri-urban hospita...
