Expulsion of Carriers from the Double-Barrier Quantum Well and Investigation of Its Spectral and Transport Consequences

Description: In this work I investigate the expulsion of carriers from nanostructures using the double-barrier quantum well (DBQW) as an example and discuss manifestations of this effect in the spectrum of the DBQW in absence of bias, and in the tunneling current in presence of bias. Assuming equality of the Fermi energy in all regions of the considered system, I compute the relative density of carriers localized in the DBQW and conclude that a fraction of carriers is expelled from this nanostructure.

Perceptions of the Sudanese Professional Working in Saudi Arabia on Migration and Economic Development of the Sudan

Description: The brain drain emerged as a phenomenon in the Sudan in the early 1970's when a change in the political system was followed by a change in the economic situation. The oil price increases created a dynamic process that led to attractive employment conditions in the petroleum producing countries such as Saudi Arabia and to depressed economic conditions in the developing countries like the Sudan. The purposes of the study are to (a) obtain information on the Sudanese professionals working in Saudi… more

Prospective Memory and College Students: Validation of the Wood Prospective Memory Test

Description: This study provides information regarding the validity and reliability of the Wood Prospective Meory Test (WPMT), a newly developed test consisting of three main subscales intended to measure prospective memory. Subjects were 69 college students (50 female, 19 male, age range 18-24), who were administered several memory tasks including the WPMT.The results of this study suggest that the subscales of the WPMT do not have sufficient internal reliability (.50, .60, and .44), and therefore, would b… more

The Relationship of Adult Attachment Styles to Working Models and Behaviors in Marriage

Description: The relationship between adult attachment style and romantic relationship quality in marriage relationships was explored. Romantic relationship quality was measured at the working model (or perceptual) and the behavioral levels. No previous research had investigated romantic relationship quality as reflecting specific attachment related perceptions of self and spouse or as attachment related behaviors. Two hundred and six married subjects were recruited from university campuses, churches, and o… more
