Comparative Ultrastructural Study between Young and Adult forms of Trypanosoma Lewisi

Comparative Ultrastructural Study between Young and Adult forms of Trypanosoma Lewisi

Date: August 1973
Creator: Abdul-Salam, Jasem M.
Description: The purpose of this study was to examine the ultrastructure of both young (dividing form) and adult (stationary form) of Trypanosoma lewisi. Changes observed between the two forms of the organism were related directly to data obtained from previous comparative biochemical studies conducted on these forms of Trypanosoma lewisi.

Jacques-Antoine-Hippolyte, comte de Guibert: Father of the Grande Armée

Jacques-Antoine-Hippolyte, comte de Guibert: Father of the Grande Armée

Date: May 2011
Creator: Abel, Jonathan
Description: The eighteenth century was a time of intense upheaval in France. The death of Louis XIV in 1715 and the subsequent reign of Louis XV saw the end of French political and martial hegemony on the continent. While French culture and language remained dominant in Europe, Louis XV's disinterested rule and military stagnation led to the disastrous defeat of the French army at the hands of Frederick the Great of Prussia in the Seven Years War (1756-1763). The battle of Rossbach marked the nadir of the French army in the Seven Years War. Frederick's army routed the French infantry that had bumbled its way into massed Prussian cavalry. Following the war, two reformist elements emerged in the army. Reformers within the government, chiefly Etienne François, duc de Choiseul, sought to rectify the army's poor performance and reconstitute France's military establishment. Outside the traditional army structure, military thinkers looked to military theory to reinvigorate the army from within and without. Foremost among the latter was a young officer named Jacques-Antoine-Hippolyte de Guibert, whose 1772 Essai général de tactique quickly became the most celebrated work of theory in European military circles. The Essai provided a new military constitution for France, proposing wholesale ...

Factors Affecting Academic Interest and Self Perception of Adolescent Hispanic Females

Factors Affecting Academic Interest and Self Perception of Adolescent Hispanic Females

Date: August 2007
Creator: Abel, Karen
Description: This investigation identifies deterrents to the educational, social, and cultural success of Latina adolescent females. Across the nation, and especially in states such as Texas and California, the Hispanic population is fast becoming the largest minority in society. Because the adolescent Hispanic population within the United States today will comprise much of America's future economic and social base, identifying and addressing educational, cultural, and social deterrents to their success becomes important not only for personal well-being, but for the well-being of future society as a whole. A second purpose was that of determining the efficacy of group-centered psychoeducational therapy in improving self-esteem and decreasing anxiety and depression symptoms in adolescent female Hispanic high school students. The experimental groups consisted of one group of seven female Hispanic adolescents who received computer and internet training and psychoeducational group counseling twice a week for five weeks. and a second group of five female Hispanic adolescents who received computer and internet training and psychoeducational group counseling twice a week for five weeks. The control group consisted of fourteen female Hispanic students who received no treatments. The Beck Depression Inventory was used to measure pre and post test levels of depression, the Beck Anxiety Inventory ...

A Study of the Relationship Between the Levels of Self-Awareness within Students Enrolled in Counseling Practicum and the Measurements of Their Counseling Effectiveness

A Study of the Relationship Between the Levels of Self-Awareness within Students Enrolled in Counseling Practicum and the Measurements of Their Counseling Effectiveness

Date: August 2002
Creator: Abney, Paul C.
Description: Counselor self-awareness is considered an important aspect of counseling effectiveness according to the American Counseling Association and the American Psychological Association and in numerous studies and articles within the counseling literature. With the effort to improve the effectiveness of counseling practicum students comes the need to understand the relationship between effectiveness ratings and the levels of counselor self-awareness. Gestalt Therapy literature, and the development of the Personal Orientation Inventory (Shostrom, 1963) provided the working definition of self-awareness in this study. Research and evaluation are means for improving the correlation between students' characteristics in counselor training programs and their effectiveness as perceived by faculty and doctoral supervisors. The purpose of this study was to determine the effects of practicum students' ages and their levels of self-awareness upon counseling effectiveness as measured by faculty and doctoral supervisors in a university clinic setting. Twenty-nine students who were enrolled in four practicum classes were administered the Personal Orientation Instrument. Four faculty supervisors and eight doctoral supervisors were administered the Counselor Effectiveness Rating Scale (Myrick & Kelley, 1971). The instruments were administered in the tenth week of the counseling practicum semester. Analyses of the data revealed a statistically significant interaction between the older practicum students' ...

Finitness and Verb-Raising in Second Language Acquisition of French by Native Speakers of Moroccan Arabic

Finitness and Verb-Raising in Second Language Acquisition of French by Native Speakers of Moroccan Arabic

Date: August 1996
Creator: Aboutaj, Heidi H. (Heidi Huttar)
Description: In this thesis, the three hypotheses on the nature of early L2 acquisition (the Full Transfer/Full Access view of Schwartz and Sprouse (e.g., 1996), the Minimal Trees view of Vainikka and Young-Scholten (e.g., 1996), and the Valueless Features view of Eubank (e.g., 1996)), are discussed. Analysis of the early French production by two native speakers of Moroccan Arabic is done to determine if the L1 grammar is transferred onto the L2 grammar. In particular, the phenomena of verb-raising (as determined by the verb's position vis-a-vis negation) and finiteness are examined. The results of this study indicate that the relevant structures of Moroccan Arabic do not transfer onto the emerging French grammar.

Ultrafast Laser Sampling of a Plant Tissue and ion Conductivity Measurement for Investigation of Light Stress Generation Mechanisms

Ultrafast Laser Sampling of a Plant Tissue and ion Conductivity Measurement for Investigation of Light Stress Generation Mechanisms

Date: August 2010
Creator: Abtahi, Seyed Ali
Description: In this study we applied ultra-short laser pulses on a biological sample (Arabidopsis), in order to cut it precisely in a square pattern and subsequently use it for studying stress generation mechanisms. For this purpose, we utilized femtosecond laser pulses at 100 fs pulse width and 80 MHz repetition rate. We took two processing parameters into consideration such as laser power, laser exposure time which is related to the stage speed. Therefore, we were able to find the laser optimum conditions for ablation of biological tissues. The mutant and wildtype (control) obtained from laser cutting with a size of 500 µm × 500 µm were directly transferred (in-situ with laser cutting) into a microfabricated chamber containing ~500 nanoliters deionized water for measuring ion conductivity. The ion conductivity is a signature of cell-death mechanisms caused by various stresses. A light with intensity of 100 µmol was exposed to the samples for 2 hours and 20 minutes as a source of stress. A quantitative electrical analysis with high accuracy was assured by utilizing a microchamber, which enables a measurement in nanoliter volume. We measured the impedance which is reciprocal of conductivity using a lock-in amplifier and a precise current source at frequency ...
