Immunotaxonomic studies have largely been based
on serology in which either one of two parameters has
been used for establishing relationships: (1) the number
of precipitin arcs formed on Ouehterlony plates, or
(2) the total amount of precipitin resulting from
reactions with a standard antiserum.
Recognizing the restrictions of both...
In this study, I seek to examine undergraduate STEM majors’ beliefs about and attitude towards mistakes in the context of counting. This is a particularly fruitful setting for such an investigation both because combinatorics is widely applicable to various fields such as physics, biology, chemistry, and computer science (Kapur, 1970),...
Combinatorics is a field of mathematics that concerns enumeration and existence, and its most notable applications are in computer science and statistics. Most students are introduced to combinatorics through counting problems, where they are tasked with determining the cardinality of a set of outcomes. Such problems are well-known for being...
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...
Counting problems are rich in opportunities for students to make meaningful mathematical connections and develop non-algorithmic thinking; their accessible nature and applications to computer science make counting problems a valuable part of mathematics curricula. However, students struggle in various ways with counting, and while previous studies have indicated that listing...
The feasibility of fluidized bed combustion of coal for commercial
and industrial steam power generation has been established
and reported in the literature. Satisfactory removal of sulfur
oxides from the combustion product gases has also been reported.
In this experiment various heat exchanger tube patterns,
of commercial size tubes, were...
