A general theory of flooding implementing the cuspoid catastrophe

Creator:: Lafi, Abd Y.
Abstract:: The flooding phenomenon can be defined as the maximum attainable flow condition beyond which the well defined countercurrent flow pattern can no longer exist. Thus the countercurrent flow limit (CCFL) or the flooding limit may be thought of as the flow condition at which the strong interaction between the two...

A role for maize ROP2 GTPase in the male gametophyte

Creator:: Carroll, Kirstin Arthur
Abstract:: ROP GTPases are crucial regulators of pollen tube growth. The Rop GTPase family in maize consists of nine known rop genes, ropl-rop9. A subset of these genes (rop2, rop8, and rop9) are expressed in pollen. The rop2 and rop9 genes are a highly conserved duplicate gene pair of ancient origin....

A study of El Niño/southern oscillation : numerical experiments and data analysis

Creator:: Ahn, Joong Bae
Abstract:: For the purpose of investigating the fundamental nature of the interannual oscillation observed in the tropical Pacific in conjunction with El Nino/Southern Oscillation (ENSO), the Comprehensive Ocean Atmosphere Data Set was analyzed. Based upon this analysis, an "intermediate" tropical atmosphere-ocean coupled model was developed. For reason of their particular importance...

A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

Creator:: Park, Heeyong
Abstract:: The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...

Analysis and modeling of electrically long MESFETS and coupled schottky lines

Creator:: Mohammed, Ahmed Sarhan
Abstract:: The properties of linear active coupled lines consisting of electrically long GaAs MESFET structures are investigated for possible applications as traveling-wave broad-band amplifiers. In addition, the nonlinear coupled Schottky lines are studied for applications as voltage tunable circuit elements. The analysis of the general active asymmetric coupled transmission lines in...

Characteristics of two noncarotenogenic light sensitive mutants of Scenedesmus obliquus strain D₃

Creator:: Harvey, Geoffrey W.
Abstract:: Two light sensitive mutants of the green alga Scenedesmus obliquus strain D₃ have been characterized. The photodynamic nature of their sensitivity has been established, the subchloroplast site of photodamage has been investigated, and their noncarotenogenic character has been verified. The two mutants possess several similarities, although mutant L. S. -41...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

Crimes Against Rhinoceros: Exploring Attitudes and Perceptions of Stakeholders in South Africa

Creator:: Kuchy, Andréa L.
Abstract:: African rhinoceros, once abundant across Africa, face threats to their long-term survival primarily due to the syndicated poaching of their horns for Traditional Asian Medicine and as status symbols in Asia. Most studies focusing on the human dimensions of rhinoceros poaching have been limited to examining a few aspects of...
