RISK: Health, Safety & Environment (1990-2002)

[Excerpt] "An unindexed journal is of little use over the long haul, and many libraries will not subscribe to it. [Of course, we plan to include at least an author and title index in the next issue, but that doesn't count.] Therefore, we were pleased to learn that Risk has been approved by the Indexing Periodical Literature Advisory Committee [One of the few which may not need nonexpert members!] of the American Association of Law Libraries. This means, for example, that Risk will be included in the Current Law Index, Legaltrac, and Legal Resources Index published by Information Access Company."

Public Accountability Of Advisory Committees, Sidney A. Shapiro Jun 1990

Public Accountability Of Advisory Committees, Sidney A. Shapiro

RISK: Health, Safety & Environment (1990-2002)

The final paper from the symposium on public participation in Risk management discusses existing procedures for ensuring the integrity of advisory committee recommendations. It concludes that they are inadequate and argues that accountability would be better served if nonexperts were included. It also suggests that, in any event, measures need to be taken to indicate, e.g., the bases for committee conclusions.

Journal of the Iowa Academy of Science: JIAS

Because their flowers can be cross- and/or self-pollinated Verbena stricta, V hastata and V urticifolia are facultatively xenogamous. We suggest the flowers can be cross-pollinated because I) the fruit set of caged plants was substantially lower than that of open-pollinated plants, i.e. pollinators were necessary for typical fruit set and 2) the flowers of each species attracted a diverse array of hymenopteran, dipteran and lepidopteran pollinators that were capable of moving pollen between plants. Self-pollination was low due to the spatial separation of anthers and stigmas and/or an angled corolla that decreased the likelihood of pollen dropping from the anthers …

Atmospheric Response To 1988 Drought Conditions And Future Climate Implications, Michael D. Mccorcle Jan 1990

Atmospheric Response To 1988 Drought Conditions And Future Climate Implications, Michael D. Mccorcle

Journal of the Iowa Academy of Science: JIAS

Plentiful precipitation in the central United States is one of the basic components of the successful agricultural industry in the Corn Belt. A combination of moisture, wind, and topographic factors creates an ideal condition for rainfall over most of the region during the late spring and early summer. In 1988, many ingredients necessary for wet weather were absent. The region experienced a drought unequalled since the 1930's. The drought of 1988 demonstrated chat the symptom of drought, namely, dry soils, can exacerbate and even perpetuate drought conditions by decreasing available moisture, altering circulation patterns vital to storm development, and increasing …


Impact Of Global Warming And Cooling On Midwestern Agriculture, Louis M. Thompson Jan 1990

Impact Of Global Warming And Cooling On Midwestern Agriculture, Louis M. Thompson

Journal of the Iowa Academy of Science: JIAS

The global warming since 1980 has been greater than it was during the warming trend from 1880 to 1940. This has caused concern that the very warm years of 1987 and 1988 might have been associated with greenhouse warming. However, the cooling trend from 1940 to 1980 occurred during a rapid buildup in greenhouse gases in the atmosphere. Although there may have been some greenhouse warming since 1880, the unusual warmth of 1987 and 1988 may have been caused by changes in the temperature of the equatorial Pacific Ocean, and changes in transparency of the atmosphere or ocher phenomena acting …


Population Estimates And Geographic Distribution Of The Yellow Mud Turtle (Kinosternon Flavescens) In Iowa, James L. Christiansen, Benny J. Gallaway, John W. Bickham Jan 1990

Population Estimates And Geographic Distribution Of The Yellow Mud Turtle (Kinosternon Flavescens) In Iowa, James L. Christiansen, Benny J. Gallaway, John W. Bickham

Journal of the Iowa Academy of Science: JIAS

The yellow mud turtle (Kinosternon flavescens) is an endangered species in Iowa known from six localities in the stare. The only large population is located on a private preserve on Big Sand Mound in Muscatine and Louisa Countries and is estimated to consist of 2,000 to 3,000 individuals. Following the removal of predators in 1979, density estimates have tripled as estimated by the Sequential Bayes Algorithm of mark-recapture data. Assuming the Big Sand Mound population was nor severely damaged by the drought of 1988, it is judged sufficiently large to serve as a source to enrich certain of Iowa's other …

Engineering Proteinase Inihibitor Genes For Plant Defense Against Predators, Clarence A. Ryan, Thomas Moloshok, Gregory Pearce, Gynhueng An, Robert W. Thornburg, Gerald Hall, Russell Johnson, Edward E. Farmer, Curtis Palm Jan 1990

Engineering Proteinase Inihibitor Genes For Plant Defense Against Predators, Clarence A. Ryan, Thomas Moloshok, Gregory Pearce, Gynhueng An, Robert W. Thornburg, Gerald Hall, Russell Johnson, Edward E. Farmer, Curtis Palm

Journal of the Iowa Academy of Science: JIAS

Small proteinaceous inhibitors (Mr<20,000) of the digestive serine proteinases of animals and microorganisms are found as moderately abundant proteins in storage organs and leaves of many plant genera. The proteins are powerful inhibitors of the digestive enzymes of plant predators and therefore are considered to be part of the array of defensive chemicals of plants. Proteinase inhibitor genes show excellent promise, using DNA technology, to manipulate plant genomes to express these biologically active proteins in order to improve natural defense systems. Members of two unrelated families of serine proteinase inhibitors found in tomato and potato plants, called Inhibitor I (monomer Mr 8000) and Inhibitor II (monomer Mr 12,300), are under both environmental and developmental regulation in different tissues of the plants. Genes coding for wound-inducible Inhibitors I and II have been isolated from both tomato and potato genomes and characterized. Tobacco plants have been transformed with the chimeric genes containing wound-inducible promoters fused with the reporter gene, chloramphenicol acetyl transferase, to assess promoter function and signal transmission. Transacting factors that regulate their expression in response to wounding are also being identified and purified. Intact genes are being employed to transform agriculturally important crop plants to determine their potential usefulness to enhance defensive capabilities of plants against herbivores and pathogens.

Comparison Of Methods For Purification Of Dna From Rice, Theresa L. Hines, Neela R. Patel, Daoud Abu-Diab, Michael Sikes, Alvan K. Karlin

Journal of the Arkansas Academy of Science

Three techniques were employed to purify genomic DNA from deomstic rice (Oryza sativa L). Following extraction, the DNA was electrophoresed through agarose to determine its integrity. We determined that spooling yielded better quality, through lower quantity DNA than either of the other two techniques.


Radon Measurements In Houses In Eastern And Central Iowa, C. V. Weiffenbach, T. J. Hart Jan 1990

Radon Measurements In Houses In Eastern And Central Iowa, C. V. Weiffenbach, T. J. Hart

Journal of the Iowa Academy of Science: JIAS

Radon concentrations in air in main floor areas of 213 houses in Central and Eastern Iowa were measured with alpha track detectors integrating over periods of five months to one year. Forty-two houses in Central Iowa had significantly higher radon concentrations (lognormal distribution with geometric mean 2.1 pCi/L, geometric standard deviation 2.2, and arithmetic mean 2.75 pCi/L) than 171 houses studied in Eastern Iowa (geometric mean 1.6 pCi/L, geometric standard deviation 2.2, arithmetic mean 2.1 pCi/L). Significant differences in radon levels were found among different categories of houses with regard to ventilation rate, basement construction, and cracks and openings in …


The Live Sheep Export Industry, Richard Norris, Barry Richards, Tony Higgs Jan 1990

The Live Sheep Export Industry, Richard Norris, Barry Richards, Tony Higgs

Journal of the Department of Agriculture, Western Australia, Series 4

Australia's live sheep trade to Middle Eastern countries is an important export industry. However, about 2 per cent of the sheep die, mainly during the sea voyage. The Western Australian Department of Agriculture has conducted a major research programme to improve the health and welfare of sheep during live export. The programme has'examined many aspects of the export sheep industry, and a substantial part of it has focused on why sheep die during sea transport.

Climate Trends In Iowa, Richard E. Carlson Jan 1990

Climate Trends In Iowa, Richard E. Carlson

Journal of the Iowa Academy of Science: JIAS

Long-term trends for various weather elements are presented for the period 1900-1988. Summer and winter season, and annual air temperature patterns are statistically weak because of large inrerannual variability, but trends are evident. There was a general warming from 1900 until the 40's, with a leveling or slight cooling following. Since the mid-70's, a warming trend seems to be taking place, but this cannot be confirmed. Spring season air temperatures showed no trend except that the most recent 4 years (1985-1988) were decidedly warmer than normal. Winter season air temperatures showed a change in trend in the 30's, but the …


Computed Normal Range Of Iowa Statewide July Precipitation, H. C. Vaughan, D. S. Sheets, G. R. White Jan 1990

Computed Normal Range Of Iowa Statewide July Precipitation, H. C. Vaughan, D. S. Sheets, G. R. White

Journal of the Iowa Academy of Science: JIAS

Iowa summer rainfall distributions are examined to identify small-scale anomalies. Examination of extremely wet and dry summer months shows that large rain amounts fall mainly in small, cellular areas for both extremely wet and dry months. These configurations result from individual rainfall events. Analysis of the distribution of mean July rainfall across the state reveals significant anomalous wet and dry regions that contrast with the background, east-west rainfall gradient. Because of the skewed nature of summer rainfall distributions, the median value is used to represent a more realistic expected rainfall amount for any given year. Some parts of the stare …

Bibliography Of The Natural And Cultural History Of The Loess Hills Of Iowa, Dean M. Roosa, Darwin D. Koenig Jan 1990

Bibliography Of The Natural And Cultural History Of The Loess Hills Of Iowa, Dean M. Roosa, Darwin D. Koenig

Journal of the Iowa Academy of Science: JIAS

A bibliography of literature on Iowa's Loess Hills includes references containing information on the cultural or natural history of chis western Iowa landform region. The bibliography is divided into six parts: general, archaeological, botanical, geological, historical, and zoological. Annotations are included only where necessary to clarify contents. Because of their rugged topography, the Loess Hills of western Iowa have resisted large-scale conversion to agriculture. This has permitted noteworthy persistence of native prairies and woodlands, along with their associated species. This bibliography complements two special issues of the Proceedings of the Iowa Academy of Science devoted to Iowa's Loess Hills.
