Studies on Lake Erie's littoral algae; Host specificity and temporal periodicity of epiphytic diatoms

Substratum specificity and temporal periodicity of the attached diatom flora upon three aquatic vascular plants and an artificial substratum were examined in three Lake Erie marshes. No qualitative or quantitative specificity for substrata was observed. Variability of diatom assemblage structure within replicate samples of a particular substratum type was as great as, or greater than, variability between substrata. Diatom assemblages upon dowel rod displayed a mid to late summer density maximum. Variability of density maxima upon natural substrata was attributed to different growth rates of the host macrophytes. Diatom assemblages within each sampling site possessed a distinct temporal periodicity indicating that factors affecting diatom growth are heterogeneous in distribution throughout Lake Erie's littoral zone.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42923/1/10750_2004_Article_BF00013712.pd

Collection on women in Alabama, W.0005

Abstract: A variety of materials related to several Alabama women, some of whom we well-known in Alabama and the nation, while others were simple women going about their daily lives. This is also the affirmative side of a debate speech presented by Benjamin F. Eborn at Southern University in Greensboro, Alabama, on the question "Is Woman Really Better Than Man?"Scope and Content Note: The collection includes letters, diaries, and one speech related to individual Alabama women. Several of the letters relate to the life of Mrs. Robert Douglas Johnston, the founder of the Alabama Boys Industrial School. There are also two letters written by Dixie B. Graves, the wife of Alabama governor Bibb Graves. Other notable items include the notebook of a Blocton woman documenting the actions of her abusive husband; a letter from Sue S. White of the National Women's Party discussing the failed suffrage ratification attempts in Alabama; a letter written by Angeline M. Krecker in 1853 describing life in Mobile; and the transcript of a speech delivered by B. F. Eborn in the late nineteenth-century, debating the question, "Is woman really better than man?"Biographical/Historical Note

On the binding energy values and excited states of some a ≧ 10 hypernuclei

New binding energy values for the hypernuclei 10ΛBe and 14ΛC have been determined while those of 13ΛC and 15ΛN have been reassessed. The existence of a narrow particle-unstable state of 12gLC is affirmed but the previously quoted evidence for the existence of a narrow state of the 14ΛN hypernucleus is shown to be invalid. © 1974.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

High Thermoelectric Power Factor Organic Thin Films through Combination of Nanotube Multilayer Assembly and Electrochemical Polymerization

In an effort to produce effective thermoelectric nanocomposites with multiwalled carbon nanotubes (MWCNT), layer-by-layer assembly was combined with electrochemical polymerization to create synergy that would produce a high power factor. Nanolayers of MWCNT stabilized with poly­(diallyldimethylammonium chloride) or sodium deoxycholate were alternately deposited from water. Poly­(3,4-ethylene dioxythiophene) [PEDOT] was then synthesized electrochemically by using this MWCNT-based multilayer thin film as the working electrode. Microscopic images show a homogeneous distribution of PEDOT around the MWCNT. The electrical resistance, conductivity (σ) and Seebeck coefficient (<i>S</i>) were measured before and after the PEDOT polymerization. A 30 bilayer MWCNT film (<1 μm thick) infused with PEDOT is shown to achieve a power factor (PF = <i>S</i>²σ) of 155 μW/m K², which is the highest value ever reported for a completely organic MWCNT-based material and competitive with lead telluride at room temperature. The ability of this MWCNT-PEDOT film to generate power was demonstrated with a cylindrical thermoelectric generator that produced 5.5 μW with a 30 K temperature differential. This unique nanocomposite, prepared from water with relatively inexpensive ingredients, should open up new opportunities to recycle waste heat in portable/wearable electronics and other applications where low weight and mechanical flexibility are needed

Overview and Preliminary Findings 1

An earlier version of this paper was presented at the Meetings of the American Sociological Association, Miami Beach, Florida, August 1993. The opinions expressed herein are those The Wisconsin Longitudinal Survey (WLS) is a long-term study of more than 10,000 women and men who graduated from Wisconsin high schools in 1957 and who have been followed for 36 years, to ages 53-54. We briefly review the design, history, and purposes of the WLS, focusing on the design and content of the 1992-93 follow-up surveys. Using preliminary data, we describe the lives of the 1992-93 respondents, with particular emphasis on health and well-being at mid-life. Using data from earlier rounds of th
