- Methylglyoxal Effects on Cell Division of Scenedesmus quadricauda (Scenedesmaceae)
- 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 inoculated with high cell numbers were less sensitive, but still showed high specific growth rates in logarithmic phase. Cell division in cultures which had low cell numbers was inhibited by 0.5 mM methylglyoxal treatment. Both specific activity of Glyoxalase I and the ratio of Glyoxalase I to Glyoxalase II of methylgloxal-treated cultures were higher than those of controls (1.3 and 2.1- fold, respectively). Pyruvate concentration in treated cultures was increased after methylglyoxal treatment.
- Comparative Labor Policy in the Hashemite Kingdom of Jordan, 1961-1987
- It is increasingly recognized that manpower planning and policies are a major component of a country's development efforts. The purpose of this study is to examine the labor market in Jordan and to identify the main determinants of employment (labor force) during the period from 1961 to 1987 in order to advise policy makers as to the best course of action to achieve full employment. This period was divided into two periods: 1961 to 1972 and 1973 to 1987 for comparative purposes. The socio-economic and political framework of the labor market, as well as the labor policies during the period were examined in an effort to determine the determinants affecting the labor market in the two periods. The findings of this study reveal that Jordan's labor market and policies over the last three decades have been influenced by changes and events not only in Jordan, but by changes and events in the entire region. The study also indicates that factors influencing the labor market differ under different conditions. The impact of the independent variables tested in this study differ between the two periods, 1961 to 1972 and 1973 to 1987. Policy which may serve the country's best interest during the time of instability and crisis may not be in the country's best interest in time of stability and peace.
- Mark Twain: "Cradle Skeptic"
- 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 reform and institutions were products of his family heritage, his social environment, and his early reading. Chapter 1 introduces the major premises of the study, and Chapter 2 reviews the critical background. Chapter 3 discusses the family and hometown influences: on Twain's skeptical thought, and Chapter A discusses Twain's early literary and philosophical influences. Chapter 5 examines Twain's early writings in letters and frontier tales and sketches, showing the development of his anti-religious attitudes. Chapter 6 concludes the study.
