A practical and versatile instrument has been developed both to
optimize the chemistry of bio- and chemiluminescence reactions and to
measure ultra-trace quantities of associated analytes. The instrument
consists of a pneumatic flow injection system linked to a detection cell and a
signal processing and readout system. The disk-like cell...
A high-spectral resolution laser-excited molecular fluorescence
system was developed that utilizes a pulsed supersonic expansion to
simplify the fluorescence excitation spectra of large, gas-phase
aromatic molecules diluted in an excess of a monatomic gas. A
microcomputer was used to control and synchronize the instrumental
components, which included a Chromatix CMX-4...
This paper describes the design and implementation of
COLAN V, a High Performance Local Area Network for
Communications and Control utilizing a Communications Coprocessor.
The main objective of this thesis is to improve upon
the performance of previous COLANs in speed, switching
techniques and error detection techniques. This was
possible...
This study was to determine the common competencies needed in
physical education graduate curricula as perceived by physical
education teachers and other physical educators in Thailand, to
determine if differences existed among three groups of physical
educators on the Importance of Content and Level of Learning of
the selected competencies,...
Generalisation is a key component of mathematical activity. Mathematicians often seek general formulae or wonder if a rule that holds in a particular dimension also holds in dimension n. However, generalisation is not limited to professional mathematicians; kindergarteners engage in generalisation when they seek patterns and algebra is sometimes described...
Sediments on the inner portion of the Oregon continental shelf
consist of clean, well-sorted, detrital sand. This sand has an average
median diameter of 2.53Φ (. 173 mm) and is both positively and
negatively skewed. Deposits with median diameters in the coarse
sand and gravel classes occur at depths of...
