This master's thesis gives a thorough and pedagogical introduction to the Dijkgraaf-Vafa conjecture which tells us how to calculate the exact effective glueball superpotential in a wide range of N = 1 supersymmetric gauge theories in four space-time dimensions using a related matrix model. The introduction is purely field theoretical and reviews all the(More)
Female spotted hyenas (Crocuta crocuta) have an erectile peniform clitoris and a pseudoscrotum but no external vagina, all established by day 35 of a 110-day gestation. Recent studies indicate that these events are androgen-independent, although androgen secretion by fetal ovaries and testis was hypothesized previously to induce phallic development in both(More)
As modern business and financial institutions have come to rely more and more on large scale computers for management support, the magnitude of the risks and their potential consequences has increased correspondingly. In addition, large systems involving multiprocessing, resource sharing, and distributed processing have given rise to a new generation of(More)
The action of methotrexate, actinomycin D, bleomycin, vincristine and hydroxyurea on the production of human chorionic gonadotrophin (hCG) by a choriocarcinoma cell line (BeWo) has been studied. hCG production per unit of cell protein was increased, and this was a continuing process only halted by cell death. The proportion of hCG-producing cells in the(More)
Single cysteine mutants of calmodulin, Cam(S38C) and Cam(N111C), have been specifically labelled with Alexa488 maleimide to study the effects of calcium on the structural dynamics of calmodulin complexed with IQ3, IQ4 and IQ34 target peptide motifs of mouse unconventional myosin-V. Using phase fluorometry, the time-resolved anisotropy shows well-separated(More)
Forty-six undergraduate business school students and forty-eight middle-level management personnel from a large manufacturing company took part in a laboratory experiment designed to examine the impact of internal-external locus of control on the relationship between budgetary participation and performance. Results indicated that, as hypothesized,(More)
