A procedure for evaluating the precision of atomic absorption
measurements is presented and applied to 21 elements under varying
instrumental conditions. The experimental relative standard deviations
(RSD's) in absorbance obtained from repetitive measurements made
with a high resolution voltmeter and on-line computer, are compared
to those predicted by a recently...
Whole body vibration (WBV) is widely used as a mechanical stimulus for neuromuscular training, and to a lesser extent, in the treatment of patients undergoing physical rehabilitation. PURPOSE: To quantify any beneficial and/or synergistic effects associated with the longitudinal administration of WBV and progressive resistance (PRE) exercise on lower extremity...
The purpose of this study was to apply instructional system theory to the
process of developing authentic English as a foreign language (ESL) materials
for Indonesian pre-departure scholars. The researcher established a theoretical
framework for the process through an intensive review of instructional system
literature and selected an applied process...
The purpose of this study was to develop and test a model in which
video materials are effectively used to develop students' listening
communication ability. In order to reach this goal, the researcher
designed the study procedure. In phase one, literature was reviewed to
establish the theoretical framework for the...
During his lifetime C. S. Lewis chose to speak to Christians in plain and simple language that they could understand. Lewis taught and defended truths that he felt were discernible through reason. Morality, free will, and the divinity of Jesus Christ were fundamental to his core beliefs and teachings. His...
Purpose of the Study:
The purpose of this study was to analyze, in the mathematics
classrooms, career-oriented verbal mathematics problems on the
achievement and attitude of the vocational mathematics student.
These career-oriented mathematics problems, used as advanced
organizers, were contrasted with mathematics word problems of a
more abstract and generalized...
This research presents the Colorado River basin as a social-ecological
system. Utilizing event data on cooperative and conflictive interactions over fresh water, the system is decomposed to look for evidence of outcomes of resilience enhancement. The Animas-La Plata Project in the upper San Juan basin is presented as a case...
In 1952, at the height of the McCarthy era, Franz Kallmann, a Jewish psychiatrist and eugenicist who fled the National Socialist regime in Germany, published a study, in which he claimed to have found a one hundred percent concordance rate for homosexuality among forty pairs of identical twins. From this...
Basalts of both Eocene and Miocene age from several groups
along the Oregon and Washington coasts have been analyzed for some
major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed
in these samples are used for comparisons within the groups studied...
