Geometric rule learning by pigeons
(2007-05-15)
In a series of four experiments using an open field search task, pigeons were trained to find a goal located at the midpoint of the hypothetical line connecting two discrete landmarks positioned in a linear array. Pigeons ...
A Study on the Adsorption Properties of Quaternized Cellulose
(2005-12-15)
The aims of this investigation explore an efficient way to remove the anionic dye for textile wastewater, and characterize surface thermodynamics of quaternized cellulose fiber by inverse gas chromatography (IGC) using ...
Yolk androgen deposition in two passerine species: Do females play favorites?
(2005-12-15)
Eggs of oviparous species contain variable amounts of androgens, such as testosterone (T), dihydrotestosterone (DHT), and androstenedione (A4). Previous studies in birds show that yolk androgens of maternal origin have ...
Forage quality, animal performences, and carcass traits of steers finished on winter annual ryegrass (Lolium multiflorum Lam.) pasture with varying levels of corn supplementation
(2005-12-15)
Crossbred steers (n=72) from E.V. Smith Beef Research Unit resident herd were selected to study forage based finishing systems using winter annual ryegrass (Lolium multiflorum Lam.) with varying levels of supplementation. ...
The Efficacy of DL-Methionine Methylsulfonium Chloride on Performance Characteristics and Intestinal Tract Integrity in Broilers
(2007-05-15)
DL-methionine methylsulfonium chloride (MMSC) is a methionine derivative previously shown to modulate the immune system and to protect intestinal membrane cells in humans and swine. It has also been shown to improve body ...
Effects of the soy phytoestrogen genistein on the reproductive development of immature female broiler chickens
(2007-05-15)
Developmentally inappropriate exposures to estrogenic compounds are known to alter morphology and function of the reproductive tract in various species. Chickens are continually exposed to the relatively potent estrogenic ...
Design and Characterization of Nonwoven Fabrics for Gas Diffusion Layer in Polymer Electrolyte Membrane Fuel Cell
(2007-05-15)
The aim of this research is to develop and evaluate materials for polymer electrolyte membrane fuel cells. Gas diffusion layer (GDL) is a part of membrane electrode assembly (MEA) that is the locomotive of polymer electrolyte ...
Comparative Stability of Aspirin in CSP Technologies Active-VialTM and Owens- Illinois L-8 Prescription Vials
(2007-05-15)
The traditional way of drug packaging includes a desiccant pouch along with the drug. The desiccant in the vial helps in preventing the drug degradation due to moisture in surrounding environment. This traditional packaging ...
Therapeutic effects of aniracetam on cognitive deficits induced by ethanol teratogenicity: A novel treatment approach through synaptic AMPA receptor modulation
(2007-05-15)
Ethanol exposure during fetal development can adversely affect the outcome of the offspring. Numerous mechanisms are likely to contribute to these damaging effects of ethanol on the fetus and particularly the developing ...
Phosphorylation of fetuin-A, a physiological inhibitor of insulin action, regulated by insulin and leptin
(2007-05-15)
Fetuin-A, a liver secreted phosphoprotein and rat homologue of human a2-HS-glycoprotein (AHSG), is a physiological inhibitor of insulin action. Fetuin-A-null mice exhibit improved glucose tolerance and resistance to weight ...
Models for Thermo-Mechanical Reliability Trade-offs for Ball Grid Array and Flip Chip Packages in Extreme Environments
(2007-05-15)
In the current work, decision-support models for deployment of various ball grid array devices and flip chip electronics under various harsh thermal environments have been presented. The current work is targeted towards ...
Modeling and Validation of Hitched Loading Effects on Tractor Yaw Dynamics
(2007-05-15)
This thesis develops a yaw dynamic model for a farm tractor with a hitched
implement, which can be used to understand the effect of tractor handling characteristics
for design applications as well as for new automated ...
Construction Technique and Strength of Connected Regolith Bag Structures
(2007-05-15)
Masonry Arches have been used from a long time in construction of bridges, domes and other structures. They are constructed out of voussoirs and their stability is determined by drawing a funicular polygon representing ...
Damage Prediction of Lead Free Ball Grid Array Packages Under Shock and Drop Environment
(2007-05-15)
The fatigue and damage of solder joints and also the potential for interface failure within BGA packages are caused by thermal cycling. In case of portable electronic products, fatigue is caused by repetitive drop and shock ...
Characterization and Dynamic Analysis of Damping Effects in Composite Materials for High-Speed Flywheel Applications
(2007-05-15)
The directional mechanical properties of carbon fiber reinforced composite
materials make them suitable for components of flywheel energy storage systems.
Particularly the hub-rim interface is a component where fiber ...
Development of Striae Distensae - A Mechanochemical Model
(2007-05-15)
Striae distensae, otherwise known as stretch marks, are common skin lesions found
in a variety of clinical settings. They occur frequently during adolescence or pregnancy
when there is rapid tissue expansion, but may ...
A novel finite element discretization of domains with spheroidal geometry
(2007-05-15)
We describe and analyze a new finite element discretizations for domains with spheroidal
geometry. In particular, we describe how the method can be used to approximate solutions
as well as eigenvalues and eigenfunctions ...
Hamilton Decompositions of Graphs with Primitive Complements
(2007-05-15)
A graph G is a pair (V, E) where V is the set of vertices(or nodes) and E is the set of edges connecting the vertices. A graph is called k-regular, if all of its vertices are incident with k edges. A k-factor of a graph G ...
