Development Of A Soil Carbon Index For Iowa Mineral Soils, M. M. Al-Kaisi, T. E. Fenton, J. G. Guzman, B. R. O'Neal Jan 2012

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 ...


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 Jan 2012

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 ...


Harlan's Ground Sloth (Paramylodon Harlant) (Xenarthra: Mylodontidae) From The Late Pleistocene (Rancholabrean) Of Iowa, H. Gregory Mcdonald Jan 2012

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) individuals ...


Effects Of Berberine, Chelerythrine, And Sanguinarine On Proliferation In Four Human Immortalized Cell Lines, David S. Senchina, Nisarg B. Shah, Marc G. Busch Jan 2012

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 rates ...


Perspectives: Developing And Defining Both Science And Science Education As Disciplines, Robert E. Yager Jan 2012

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 ...

Comparing Middle School Students' Learning And Attitudes In Face-To-Face And Online Mathematics Lessons, Clayton M. Edwards Jan 2012

Comparing Middle School Students' Learning And Attitudes In Face-To-Face And Online Mathematics Lessons, Clayton M. Edwards

Theses and Dissertations @ UNI

Online learning has become a staple within education for college students, and has started to enter high schools. While this instructional delivery system has been shown to work for older students, few studies have involved middle school students. If this trend toward online teaching of younger students continues, online learning could become a large part of education for middle school students, making research in this area important.

Multiple positive and negative aspects have been identified for online learning. Positive characteristics include individualized pacing; electronic resources, and the opportunity for rapid or personalized feedback, while negative aspects address increased student responsibility ...


The Inverted Classroom : A Literature Review, Jennie Kies Jan 2012

The Inverted Classroom : A Literature Review, Jennie Kies

Graduate Research Papers

Teachers struggle to thoroughly educate students in science, technology, engineering and math (STEM) related fields. This literature review examines the current research on STEM education, learning theories, and the effects of an inverted classroom on student learning in STEM classes in order to determine the possible benefits of implementation at pre-collegiate levels. Lacking research at the high school level, this paper focuses on articles describing inverted, college level STEM classes. This study indicates that further research is needed at both the high school and college level to prove that inverted classes result in improved learning and student retention; it also ...


Comparing Fossil Instruction With And Without Analogy Use For Gifted Middle-School Students, Tabatha J. Klopp Jan 2012

Comparing Fossil Instruction With And Without Analogy Use For Gifted Middle-School Students, Tabatha J. Klopp

Graduate Research Papers

Twenty-eight identified gifted elementary to middle school students (n=28) (16 female, 12 male; 26 Caucasian, 1 Hispanic, and 1 Native American), participated in the study of Iowa fossils through form and function analogy compared to self-research of information on the Internet, and practiced new concepts through technology-rich or hands-on craft projects. This study compared using analogical thinking skills along with technology skills to determine the effects on science learning in the elementary gifted classroom. Analogical thinking or teaching is a method recognized as a valuable source of new ideas, a way to transfer previous knowledge to solve new problems ...
