Methylglyoxal Effects on Cell Division of Scenedesmus quadricauda (Scenedesmaceae)

Description: Cell division of ggeneflesmus quadricauda (Turp.) Breb. (Scenedesmaceae) is enhanced by methylglyoxal, a general inhibitor of cell division, at threshold concentration in conjunction with treatment timing related to growth stage of batch cultures. At 0.5 mM methylglyoxal concentration, cell division was significantly enhanced in algae treated in the logarithmic phase. Specific growth rates of methylglyoxal-treated cultures were rapidly increased at the beginning of logarithmic phase. Cultures i… more

Comparative Labor Policy in the Hashemite Kingdom of Jordan, 1961-1987

Description: It is increasingly recognized that manpower planning and policies are a major component of a country's development efforts.

Consistency in Lattices

Description: Let L be a lattice. For x ∈ L, we say x is a consistent join-irreducible if x V y is a join-irreducible of the lattice [y,1] for all y in L. We say L is consistent if every join-irreducible of L is consistent. In this dissertation, we study the notion of consistent elements in semimodular lattices.

Children's Cognitive and Moral Reasoning: Expressive Versus Receptive Cognitive Skills

Description: Past research has shown that there are differences between children's ability to express verbally moral judgment or social cognitive principles (cognitive-expression) and their ability to understand and utilize these principles when making evaluations about others (cognitive-reception). This study investigated these differences.

Mark Twain: "Cradle Skeptic"

Description: Critics discussing Mark Twain's early skepticism have, to date, confined their explorations to short studies (articles or book chapters), brief references in passing, or buried their insights in discussions on other topics. Other critics ignore Twain's atheistic statements and see his beliefs as theistic or deterministic. Others ascribe his attitudes in the "dark writings" to late life disappointments. This study demonstrates that Twain's later attitudes towards religion, determinism, social re… more
