Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal

Journal of the Iowa Academy of Science: JIAS

A carbon index (Cl) is one of many soil quality indicators that depends on organic carbon concentration. One of the values of a soil carbon index is in determining the impact of agriculture practices (i.e., tillage, crop rotation, N management, etc.) on soil organic matter status of mineral soils. Interactions of climate, parent material, topography, time, and organisms including human activities influence soil organic carbon (SOC). This study developed a soil carbon index for mineral soil map units in Iowa using data collected by the Iowa Cooperative Soil Survey Laboratory and the USDA Soil Survey Laboratory for over 2,300 soil …

Perspectives: Developing And Defining Both Science And Science Education As Disciplines, Robert E. Yager

Journal of the Iowa Academy of Science: JIAS

The six "domains" have been identified as features for the "doing" of science. These six are: Concept, Process, Creativity, Attitude, Application, and Worldview. They are offered to affect teaching, student learning, as well as a new way of defining science. Concepts and Processes often are the only two typically used to define school and college science content; Creativity and Positive Attitudes are added as two "enabling" domains; a fifth Domain is offered as a focus on the Application of typical concepts and process skills. It is the Domain where and how most people live and operate! The sixth Domain is …

Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch

Journal of the Iowa Academy of Science: JIAS

Bloodroot (Sanguinaria canadensis L., Papaveraceae) is a plant rich in benzophenanchridine (isoquinoline) alkaloids such as sanguinarine and chelerychrine. Both isolated alkaloids and whole-tissue rhizome extracts have demonstrated in vitro anticarcinogenic (antiproliferacive) activity in limited immortalized cell culture models, but the relative contribution of various alkaloid constituents to whole-tissue extract activity, and whether or not various alkaloids may act synergistically, has not been investigated. We challenged four immortalized cell lines (Jurkat, K562, Ramos, U937) with various doses of chelerythrine, sanguinarine, and berberine (a structurally and functionally similar alkaloid absent from bloodroot), alone and in all possible combinations, and measured proliferation …

Evidence From Detrital Zircon Ages For Middle Pennsylvanian Uplift And Drainage In The Source Area Of The Chariton Conglomerate And Marmaton Group Sandstones, Southern Iowa And Northern Missouri, Scott Mcfadden, Steven H. Emerman, Jane Pedrick Dawson, Kevin A. Rey, Tracy Kemp Anderson

Journal of the Iowa Academy of Science: JIAS

The Chariton Conglomerate is a quartz/limestone conglomerate of Middle Pennsylvanian age sparsely exposed in southern Iowa and northern Missouri. In Iowa it is characterized by quartz granules and rounded crinoid columnals. The objective of this study was to use detrital zircon ages to determine the provenance of the Chariton Conglomerate and possibly associated Marmaton Group sandstone beds. Detrital zircon ages were obtained for five conglomerate and two sandstone beds of the Chariton Conglomerate in Iowa, three conglomerate beds of the Chariton Conglomerate in Missouri, and two sandstone beds of the Marmaton Group in Iowa. According to the Kolmogorov-Smirnoff Test, the …

Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald

Journal of the Iowa Academy of Science: JIAS

Harlan's ground sloth, Paramylodon harlani, is documented for the first time from Iowa. The record is based on a fifth metacarpal recovered from a gravel bar within West Tarkio Creek, Page County. While the specimen was not found in situ, and could not be radiocarbon dated, the local geology suggests that it was probably derived from sediments that post-date Peorian loess deposition and is late Wisconsinan in age. This specimen extends the range of Paramylodon 350 km ro the northeast of the closest previously known locality. Its size is slightly larger than average for other late Pleisrocene (Rancholabrean) …
