Effect of Hand Dominance on Rate of Learning and Bilateral Transfer.
People generally have a dominant and a nondominant hand. Dominance refers to the ability to perform a task better with a particular hand [Hand preference does not necessarily mean hand dominance] (Rigal, 1974). For example, a child may show tendencies to be left hand dominant; however, his parents …

On rate capacity and signature sequence adaptation in downlink of MC-CDMA system
This dissertation addresses two topics in the MC-CDMA system: rate capacity and adaptation of users' signature sequences. Both of them are studied for the downlink communication scenario with multi-code scheme. The purpose of studying rate capacity is to understand the potential of applying MC-CDMA …

The Influence of Stand Density on Rate of Carbon Sequestration in Loblolly Pine Plantations on Mined Lands in East Texas
<p>The State of Texas emits more carbon dioxide (C02) into the atmosphere than any other state in the United States. With environmental concerns escalating, the U.S. may be forced to reduce its emissions of greenhouse gases. The first target of these reductions will likely be utility companies that …

The Effects of Extinction on Human Performance Following Exposure to Fixed Ratio Schedules of Reinforcement
This experiment examined the effects of extinction on rate of responding and several topographical and temporal measures in adult humans. Three college students were trained to type the sequence 1•5•3 on a numeric keypad on a computer. The subjects were exposed to different fixed-ratio schedules of …

Bioinspired Catalysts for Phosphoryl Transfer Reactions
Phosphoryl transfer reactions are ubiquitous in biology and are usually catalyzed by metalloenzymes. For a number of phosphoryltransfer enzymes, including the exonuclease subunit of DNA polymerase I, a mechanism involving two metal ions and double Lewis-acid activation of the substrate, combined …

A study of several factors incident to the absorption of choline from the small intestine of the albino rat
<p>The substance choline, one of the quaternary nitrogen bases, has been the subject of a number of reviews and investigations. It has been described as a cholinergic agent, an inotropic agent, a vitamin, and perhaps in other ways. In spite of the interest shown in its action and uses, there is as …

High Pressure Effects on the Dynamics and Kinetics of Two Model Biochemical Systems
Pressure effects on rate constants for hydrogen exchange between N-methylacetamide (NMA) and water were measured at pressures up to 5 kbar at three different pH values and temperatures using proton/nitrogen-14 decoupled NMR inversion transfer, and the apparent activation volumes of exchange …

Robust regression methods for insurance risk classification
Risk classification is an important actuarial process for insurance companies. It allows for the underwriting of the best risks, through an appropriate choice of classification variables, and helps set fair premiums in rate-making. Currently, insurance companies mainly use ad-hoc methods for risk …

Variation in leaf attributes and their effects on physiological processes in Leucospermum conocarpodendron L. Buek
Two subspecies of Leucospermum conocarpodendron with considerable variation in leaf traits occur along the Cape Peninsula along clearly delimited geographical distributions. We attempted to quantify the difference in leaf trait dimensions between green (L. conocarpodendron ssp. viridum) and grey …

Factors affecting growth of the conceptus in lactating dairy cows and non-lactating dairy heifers
Embryonic loss in dairy cows continues during the fifth and sixth weeks of pregnancy in lactating dairy cows. There is an association between smaller embryos and pregnancy loss during this period. The objective was to examine the potential factors that affect embryonic growth from day 33 to 45 of …

Indentation vs. Uniaxial Power-law Creep of Sn-based Solder Material: A Numerical Assessment
… creep behavior of Pb-free solder alloys in electronic packaging. Typical service environments are between 298 and 373K. The thermal mismatch induced stresses acting on solder joints result in extensive rate-dependent plastic deformation. The solder alloy is potentially the weakest component in the …
