Scanning Electron Microscopy Of Styrene-Methylethylketone Casts Of The Airway And The Arterial System Of The Lung, Teruyuki Hojo
Scanning Electron Microscopy Of Styrene-Methylethylketone Casts Of The Airway And The Arterial System Of The Lung, Teruyuki Hojo
Scanning Microscopy
The method of making casts of airways and the pulmonary arterial system using a styrene polymer resin is described. A human and a dog were used as models. The viscosity of this resin ranges between 40 and 60 dPa/s at 24°C. The elastic rubber tube used for resin injection allows a constant perfusion pressure, i.e., 44 mm Hg and 110 mm Hg for airway and vascular filling, respectively. The casts obtained using this method are suitable both for macro- and microscopic analysis. Shrinkage during polymerization is minimal. Moreover, a preceding lavage is not necessary. Scanning electron microscopy (SEM) of cast …

The Pleistocene Glacial Record At Two Quarries In Decatur County, Iowa, Keith E. Schilling, Robert A. Stewart
The Pleistocene Glacial Record At Two Quarries In Decatur County, Iowa, Keith E. Schilling, Robert A. Stewart
Journal of the Iowa Academy of Science: JIAS
The Pleistocene stratigraphy and sedimentology of two quarry exposures near Grand River and Decatur City in Decatur County, Iowa document a sequence of Pleistocene sediments overlying striated Pennsylvanian limestone which represent at least two pre-Illinoian glacial advances into the ancestral Grand River valley. Two pre-Illinoian diarnictons separated by a clast pavement were observed at the Decatur City quarry; a single diarnicton was present at the Grand River quarry. At both quarries, the diarnictons exhibit comparable lithologic properties and are genetically interpreted as basal tills. The pre-Illinoian tills are tentatively correlated with the Alburnett Formation in eastern Iowa, primarily on the …
Competitive Abilities Of Oat And Barley Varieties, B. D. Mcbratney, K. J. Frey
Competitive Abilities Of Oat And Barley Varieties, B. D. Mcbratney, K. J. Frey
Journal of the Iowa Academy of Science: JIAS
Competitive ability of a plant genotype reflects its capacity to yield well and compete successfully for light, moisture, and nutrients when grown with similar or dissimilar genotypes. This trait is important to plant breeding because most breeding populations are propagated in mixed or competitive stands. The objective of this study was to assess the competitive abilities of oat and barley genotypes.
Two sets of oat and barley genotypes were evaluated for competitive ability. Set I consisted of five oat varieties, and Set II consisted of two barley and three oat varieties. Neither set, when averaged, showed over- or under-compensation with …
The Early History And Recent Trends In Iowa Herpetology, Reeve M. Bailey, James L. Christiansen
The Early History And Recent Trends In Iowa Herpetology, Reeve M. Bailey, James L. Christiansen
Journal of the Iowa Academy of Science: JIAS
Herpetological exploration of Iowa began in 1823 with Long's expedition to the Rocky Mountains. From that time until an 1892 publication by Osborn based on Iowa specimens, herpetological research in the state was minor and incidental. Several significant reports appeared after that date involving analysis of Iowa specimens and from 1938 to 1944 a major base-line collection of the amphibians and reptiles of Iowa was established. Studies after that time have added a few species to Iowa’s known herpetofauna but recently have concentrated not only on composition of the fauna and distribution, but emphasized population changes, ecological relationships, and better …
Some Significant Iowa Plant Records From The Herbarium Of University Of Nebraska At Omaha, Barbara L. Wilson
Some Significant Iowa Plant Records From The Herbarium Of University Of Nebraska At Omaha, Barbara L. Wilson
Journal of the Iowa Academy of Science: JIAS
Though the herbarium of University of Nebraska at Omaha (OMA) lies outside the state boundaries, it contains a number of interesting western Iowa records. Publicizing these and other little-known Iowa plant records is especially important at this time, since a checklist of Iowa's vascular plants, compiled by Eilers and Roosa, is nearing completion.
Assessing Animal Well-Being: Common Sense, Uncommon Science, David Fraser
Assessing Animal Well-Being: Common Sense, Uncommon Science, David Fraser
Assessment of Animal Welfare Collection
The scientific assessment of the well-being of an animal involves finding indicators of three broad criteria: 1) a high level of biological functioning; 2) freedom from suffering in the sense of prolonged fear, pain, and other negative experiences; and 3) positive experiences such as comfort and contentment. The tools available to assess animal wellbeing include a mixture of common sense and cutting-edge science. Measures of animal productivity can help to assess an animal’s level of biological functioning, but they need to be used with care. Among veterinary approaches, pathology detects breakdown in biological functioning, while epidemiology identifies the circumstances under …

Community Dynamics Of Phytoplankton In A Typical Navigation Pool In The Upper Mississippi River, Theodore R. Lange, Ronald G. Rada
Community Dynamics Of Phytoplankton In A Typical Navigation Pool In The Upper Mississippi River, Theodore R. Lange, Ronald G. Rada
Journal of the Iowa Academy of Science: JIAS
In 1986 we studied phytoplankton in the mid-reaches of Pool 8, which is a typical navigation pool of the Upper Mississippi River. During years of normal discharge, the areas studied usually become distinctly different from each other (ranging from free-flowing river to stagnant marsh) as the ice-free season progresses. These differences among sites did not occur during our study because the discharge into Pool 8 during 1986 was about 85% greater than the 10-yr mean discharge (1972-1982). Moreover, differences among areas were not observed with respect to physical and chemical characteristics such as photic zone depth, temperature, dissolved nitrogen and …

Habitat And Distribution Of Plants Special To Iowa's Driftless Area, William P. Pusateri, Dean M. Roosa, Donald R. Farrar
Habitat And Distribution Of Plants Special To Iowa's Driftless Area, William P. Pusateri, Dean M. Roosa, Donald R. Farrar
Journal of the Iowa Academy of Science: JIAS
A portion of the Upper Midwest escaped glaciation during the two most recent glacial epochs. This "Driftless Area", also known in Iowa as the "Paleozoic Plateau", comprises some 39,000 square kilometers (15,000 square miles) in the states of Illinois, Iowa, Minnesota, and Wisconsin. Today the highly dissected terrain provides a variety of habitats supporting a rich and diverse flora including many plants special to the area, i.e., principally, in Iowa, restricted to the Driftless Area. These special plants have received much attention, often having been discussed as possible relicts from past floras. However, distribution data for these species beyond the …

Review Of The Origins Of Agriculture And Settled Life By Richard S. Macneish. Norman And London: University Of Oklahoma Press, 1992. 433 Pages., Alan J. Osborn
Review Of The Origins Of Agriculture And Settled Life By Richard S. Macneish. Norman And London: University Of Oklahoma Press, 1992. 433 Pages., Alan J. Osborn
Department of Anthropology: Faculty Publications
Excerpt:
Following a brief review of the "environmentalist's" (e. g., Ratzel, de Candolle, Childe, Braidwood, and Flannery) and the "materialist's" (e. g., Marx, Vavilov, D. Harris, Binford, and Cohen) accounts, MacNeish presents his "trilinear theory." It consists of "three hypothetical models and three hypotheticaI sets of causes" for the development of plant domestication and sedentism. This "trilinear theory" is a world culture history similar to the multilinear developmental frameworks proposed "by Julian Steward (The Theory of Culture Chtange: The Methodology of Multilinear Evolution, 1955). MacNeish's multilinear scheme is cross-cut by three developmental stages, i. e., food collectors, transitional …
Mass Selection For Adaptation In Antigua Maize (Zea Mays L.) Composite, F. M. San Vicente, A. R. Hallauer
Mass Selection For Adaptation In Antigua Maize (Zea Mays L.) Composite, F. M. San Vicente, A. R. Hallauer
Journal of the Iowa Academy of Science: JIAS
Tropical maize (Zea mays L.) germplasm has had limited use in temperate areas because of photoperiod sensitivity. Antigua germplasm from the island Antigua was introduced co Iowa because of its resistance to important pests of maize and its heterosis exposed m crosses with ocher tropical varieties. Mass selection procedures were used to adapt the Antigua Composite germplasm co Iowa conditions. After. Six cycles of mass selection for earlier silk emergence, the selected Antigua Composite flowered 17 days earlier than the original composite. Grain yield and ocher agronomic traits of the adapted scram of Antigua were similar co chose of adapted …

Evaluation Of Passive Integrated Transponders As A Marking Technique For Turkey Poults, Dewaine H. Jackson, William H. Bunger
Evaluation Of Passive Integrated Transponders As A Marking Technique For Turkey Poults, Dewaine H. Jackson, William H. Bunger
Journal of the Iowa Academy of Science: JIAS
Injectable, passive integrated transponders (PITs) were evaluated as a marking technique for newly hatched wild turkey (Meleagris gallopavo Linnaeus) poults. Seven of 12, 3-day-old domestic turkey poults received a PIT implant and a wing tag. A control group of five poults received only a wing tag. Two subcutaneous implant sites were evaluated, along the right side of the neck and in the area between the right inner thigh and breast. One of7 PITs failed or was expelled during the first week. Four scanning errors, in which the PIT was present yet not detected during the initial scanning attempt, occurred in …
Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore
Range Expansion Of The Great-Tailed Grackle In The 1900s, James J. Dinsmore, Stephen J. Dinsmore
Journal of the Iowa Academy of Science: JIAS
In 1900, the range of the Great-tailed Grackle extended north of the Mexican border only into Texas. Since then, it has expanded its range greatly. It now nests in 14 states and has strayed to an additional eight states and three Canadian provinces. Much of this expansion has occurred since 1960. Great-tails often stray far from their normal range, especially in spring. Most of these strays are single individuals. In states where they have nested, breeding birds typically reach the state a few years after the first reports of the species. Great-tailed Grackles do well in a variety of human …
