Alternate Methods of Stabilizing Degrading Stream Channels in Western Iowa, Phase I, HR-208, 1980

Since the beginning of channel straightening at the turn of the century, the streams of western Iowa have degraded 1.5 to 5 times their original depth. This vertical degradation is often accompanied by increases in channel widths of 2 to 4 times the original widths. The deepening and widening of these streams has jeopardized the structural safety of many bridges by undercutting footings or pile caps, exposing considerable length of piling, and removing soil beneath and adjacent to abutments. Various types of flume and drop structures have been introduced in an effort to partially or totally stabilize these channels, protecting or replacing bridge structures. Although there has always been a need for economical grade stabilization structures to stop stream channel degradation and protect highway bridges and culverts, the problem is especially critical at the present time due to rapidly increasing construction costs and decreasing revenues. Benefits derived from stabilization extend beyond the transportation sector to the agricultural sector, and increased public interest and attention is needed.

Atipias de Células Escamosas de Significado Indeterminado (ASCUS): estudo de 208 Casos

Objetivos: avaliar aspectos clínicos, colposcópicos e acompanhamento citológico de quadros classificados como atipias de células escamosas de significado indeterminado (ASCUS). Métodos: foram analisados retrospectivamente 208 casos de ASCUS diagnosticados entre 1996 e 1998 e tabulados quanto a idade, queixas clínicas, colposcopia e seguimento. Resultados: a relação ASCUS:lesão intra-epitelial escamosa foi de 1:1,2, confirmando adequado controle de qualidade. Pacientes com menos de 35 anos corresponderam a 72,6% dos casos. Um grande número não tinha queixas clínicas (36,5%). Nos casos em que foi realizada colposcopia (n = 58), a zona de transformação atípica foi observada em 60%. A subclassificação das ASCUS em provavelmente displásico (D), provavelmente reativo (R) e não-determinado (U) indicou predominância do primeiro (65%). O acompanhamento de 86 pacientes mostrou que, após 3 a 6 meses (média de 4,5 meses), em 12,5% foi possível detectar citologicamente uma lesão intra-epitelial escamosa. Conclusão: com base nos resultados deste trabalho foi possível concluir que as ASCUS incidem em mulheres jovens, com queixas clínicas corriqueiras e apresentam correlação colposcópica positiva. Nestes casos o acompanhamento citológico se faz imprescindível para esclarecimento de lesão intra-epitelial escamosa subjacente ou subseqüente.

SEMICLASSICAL ESTIMATE OF THE COULOMB-EXCITATION OF THE GIANT-DIPOLE RESONANCE IN PB-208

A semiclassical approach to study pure Coulomb excitation of Pb-208 giant dipole isovector resonance is examined. We consider medium energy projectiles and assume the target excitation to be described by a simple Goldhaber-Teller model. It is shown that the main features concerning the angular distribution are obtained in the angular range described by the model and an estimate is made of the pure Coulomb dipole contribution to the measured cross sections.

Covenanters of South Carolina Collection - Accession 208 - M92 (118)

The Covenanters of South Carolina Collections consists of a "Sketch of the Covenanters of Rocky Creek, South carolina About 1750 to 1840" by Miss Mary Elder, 1886 as dictated to her by her father Mr. Matthew Elder, Yorkville, SC. Also included is an undated genealogical sketch of William Stinson (Stevenson) (1752-1809) who was a covenanter from Rocky Creek, SC and a "History of Fishing Creek Presbyterian Church by Mrs. Frank Hicklin" that was written ca. 1958. The Fishing Creek Presbyterian Church was organized ca. 1752.
