(2007-05-15)
Learning outcomes for students with mild learning and behavioral disabilities
(SWD) are receiving national attention as a result of educational reform focusing on
student achievement. This educational reform is the No ...
Transition Outcomes of Students with High Incidence Disabilities in Alabama
(2007-05-15)
This study examined factors associated with the engagement of former students with high incidence disabilities in Alabama from rural and nonrural school systems. The investigation was conducted using 119 students with ...
Use of Elemental and Configural Coding in Timing of Compound Stimuli
(2007-05-15)
The timing of a compound stimulus could provide important information regarding elemental and configural processing. After training with either an elemental (in which the focus was on the individual features of a stimulus ...
The Effects of Static Magnetic Fields on Directionality in Humans
(2007-05-15)
Earth produces a dipole static magnetic field that is sufficiently stable to allow derivation of directional cues in a variety of species. This ability, known as magnetoreception, has been studied primarily in birds and ...
Development of a Recombinant Noncytopathic Bovine Viral Diarrhea Virus Stably Expressing Enhanced Green Fluorescent Protein
(2005-08-15)
Noncytopathic (NCP) type-I bovine viral diarrhea virus (BVDV) strain SD1 was originally isolated from a persistently infected heifer with fatal mucosal disease (MD) and represents the only reported nucleotide sequence of ...
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
