Plasmodium Gallinaceum Release from Chicken Erythrocytes by Ultrasound

2006-07-08T06:04:44Z

Plasmodium Gallinaceum Release from Chicken Erythrocytes by Ultrasound Prior, Richard B.; Kreier, Julius P. Erythrocytes of chickens with Plasmodium gallinaceum infection were exposed to ultrasound at frequencies between ',YA4 and N57 kHz. All frequencies studied caused erythrocytc disruption and release of free parasites if the intensity was great enough, although irradiation with IYM kHz appeared to cause more rapid crythrocytc disruption at comparable intensities than did irradiation at the other frequencies studied. Cellular disruption was slower in plasma than in saline, Alsevcr's solution, or phosphate buffer. Any intensity which caused cavitation caused disruption at a rate roughly proportional to the intensity. When cavitation was suppressed, disruption was almost stopped. The probable sequence of events during sonication of erythrocytes was local damage to the membrane resulting in distortion of the erythroeyte followed by subsequent hemolysis leaving the parasite and erythrocyte nucleus enclosed in the ghost. On further sonication the membrane disrupted and both parasite and nucleus were released. If the parasites were not removed from the ultrasonic field, they, in turn, were disrupted.

A New Genus, Tenuacia, New Subgenus, Rubacea and Two New Species of Gyponinae (Homoptera: Cicadellidae)

2006-07-07T06:10:33Z

A New Genus, Tenuacia, New Subgenus, Rubacea and Two New Species of Gyponinae (Homoptera: Cicadellidae) DeLong, Dwight M. Two species of Gyponinae from Peru and Central America with similar external characteristics were studied. They are placed in a new genus, Tenuacia, and one new subgenus, Rubacea. The new genus Tenuacia, species T. macera n. sp., subgenus Rubacea and species T. (R). rubera n. sp. Gyponinae are described. In both species the head is broadly rounded and strongly produced with the eyes partly surrounded by the crown. The aedeagus in Tenuacia bears parameres but does not in Rubacea.

Species Importance within a Virgin and a Timbered Beech-Maple Forest Ecosystem

2006-07-07T06:10:32Z

Species Importance within a Virgin and a Timbered Beech-Maple Forest Ecosystem Adams, Diana L.; Barrett, Gary W. A virgin forest, Hueston Woods in southwestern Ohio, and a selectivelycut forest, Lewis Woods in east central Indiana, were sampled by a modified pointquarter method in order to evaluate the impact of timbering on community structure. Timbering occurred in Lewis Woods in 1910, 1935, and 1955. Importance values were computed for each species encountered (> 1 inch diameter breast height) within each study area in order to determine the timbering impact on community structure. Hueston Woods was clearly dominated by sugar maple (Acer saccharum) and American beech (Fagus grandifolia) with importance values of 132.6 and 117.3, respectively. Lewis Woods was characterized by a more even importance distribution patterns, although sugar maple and American beech were still found to be of greatest importance with values of 120.8 and 76.8, respectively. Sixteen species were encountered in Lewis Woods as compared to 13 species for Hueston Woods. The significance of these differences is discussed.

Feeding of Tobacco Hornworm Larvae Under Different Light Conditions as Indicated by Fecal Evacuations

2006-07-07T06:10:32Z

Feeding of Tobacco Hornworm Larvae Under Different Light Conditions as Indicated by Fecal Evacuations Stewart, Paul A.; Nelson, L. A. The periodicity of fecal evacuations of tobacco hornworm larvae (Mandue a sexto) was monitored throughout the total larval phase in constant light, constant darkness, and a fall rhythm of light and darkness. By observation of feeding behavior and fecal evacuations of larvae, the time relationship of fecal evacuation and ingestion was recorded. The interval between initial ingestion and first evacuation averaged 3.75 hr. During the intervals between molts the larvae actively fed in periods averaging 14 min. The average length of feeding periods between molts was 58 hrs and the length of molting periods 22 hrs. The total larval phase covered 375 hrs in the fall light-dark cycle, 358 hrs in continuous darkness, and 407 hrs in continuous light. The total larval phase and the total numbers of fecal pellets evacuated in the different light regimes were not significantly different.

The Translocation of Radioactive Phosphorus by the Aquatic Vascular Plant Najas Minor

2006-07-07T06:10:31Z

The Translocation of Radioactive Phosphorus by the Aquatic Vascular Plant Najas Minor Seadler, Alan W.; Alldridge, Norman The translocation of phosphorus by the aquatic vascular plant Najas minor All. was examined using radiophosphorus (32P). Whole plants showed a lack of phosphorus translocation either from the root to the shoot or in the reciprocal direction. Autoradiographic experiments indicated that the lack of translocation may be due to a very slow movement of this nutrient in both the root and the shoot. Phosphorous was calculated to move 0.6 mm/hr in roots and 1.2 mm/hr in foliage presumably through cells rather than in the vascular system.

Infant Mortality and Socioeconomic Status Among Ohio Counties, 1969-1971

2006-07-07T06:10:31Z

Infant Mortality and Socioeconomic Status Among Ohio Counties, 1969-1971 Stockwell, Edward G.; Laidlaw, Karen A. Infant mortality rate as an index of levels of social and economic well being in Ohio was studied using the 1972 County and City Data Book (U.S. Bureau of Census, 1973) as the primary data source. Infant mortality rates were fairly high in counties with more than 100,000 people even though these counties were in the highest average income class. This was due, in part, to the large minority population of lower economic status found in metropolitan centers. The inverse relation found between infant mortality and income level was more pronounced in counties with 50,000 to 99,999 individuals than in counties with less than 50,000 population.

Gradient Analysis of Secondary Deciduous Forest Vegetation Occurring on a Slope of Fort Ancient, Southwestern Ohio

2006-07-07T06:10:30Z

Gradient Analysis of Secondary Deciduous Forest Vegetation Occurring on a Slope of Fort Ancient, Southwestern Ohio Antonio, Thomas M.; Vankat, John L. A gradient analysis was made of the woody vegetation of a secondary deciduous forest on a slope in southwestern Ohio. Coefficients of similarity showed greater variation in the vegetation between different slope eposures than between different slope elevations. Greatest vegetational differences between exposures were for the north-south comparison, while the west-south exposures had the highest similarity. Greatest elevational similarity was within the west exposure. This exposure supported a northern red oak community, while the north exposure supported a sugar maple-oak community, and the south exposure supported a chinkapin oak-northern red oak community. Individual species had different patterns of distribution, indicating a continuum in the distribution of plant communities. Author Institution: Department of Botany, Miami University

2006-07-08T06:04:43Z

An Algorithm for the Computer Evaluation of Quantitative Laboratory Unknowns Based on Accuracy and Precision Mottel, Edward A.; Gordon, Gilbert An algorithm for evaluating student laboratory results is presented in which both proximity to the true result (accuracy) and the reproducibility of these results (preeision) can be evaluated. The usefulness of such a scoring device and its pedagogical advantages are presented. The results are described in terms of a computer program LAB GRADE which is available from the authors upon request.

Ancient Disease in Ohio: The Eiden Population

2006-07-07T06:10:29Z

Ancient Disease in Ohio: The Eiden Population Lallo, John W.; Blank, John E. Skeletal material from a protohistoric (A.D. 1490±55 years) Amerindian population which lived in Lorain County provided information on one of Ohio's early Indian groups. The skeletal material indicated some categories of pathology and skeletal anomalies which were present. The frequency of occurrence of these skeletal lesions were then interpreted from an cpidemiological point of view. The analyses showed the presence of the following classes of skeletal lesions: developmental anomalies, infectious diseases, degenerative conditions, neoplastic lesions, fractures, and a possible nutritional disorder. The results suggest that the adults have significantly (p < .05) higher frequencies than the subadults for developmental anomalies, infectious diseases, and degenerative conditions. Also, the adult males have significantly higher frequencies than adult females for developmental anomalies and degenerative conditions.
