Improved Functional Prediction Of Hypothetical Proteins From Listeria Monocytogenes 08-5578, Michael J. Lagier, Brittany Bowman, Kelsey Brend, Katherine Hobbs, Michael Foggia, Mark Mcdaniel

Journal of the Iowa Academy of Science: JIAS

Listeria monocytogenes is a foodborne human pathogen responsible for listerosis. The genomes of several L. monocytogenes strains have been recently sequenced. The genome of L. monocytogenes 08-5578, which was in part responsible for a significant listerosis outbreak in 2008, contains an unexpectedly high percentage of protein-encoding genes (1,927 out of 3,161; 60.96%) autonomously annotated as hypothetical proteins. The aim of this study was to test whether a manual annotation strategy could be used to assign more meaningful functional names to the hypothetical proteins of 08-5578. A holistic, manual gene annotation strategy that utilized sequence homology, cellular localization predictions, structure-based evidence, …


The Role Of An Urban Tallgrass Prairie Remnant In Conservation: A Case Study In Central Iowa (Usa), Jimmie D. Thompson, Deborah Q. Lewis, William R. Norris Jan 2014

The Role Of An Urban Tallgrass Prairie Remnant In Conservation: A Case Study In Central Iowa (Usa), Jimmie D. Thompson, Deborah Q. Lewis, William R. Norris

Journal of the Iowa Academy of Science: JIAS

Although more than 85% of Iowa (USA) was covered by tallgrass prairie at the time of settlement by Europeans in the early 19th century, less than 0.1% remains. The Richard W. Pohl State Preserve at Ames (IA) High School, surrounded on three sides by structures, roads, and other development, protects 4 ha of tallgrass prairie. The preserve, commonly referred to as Ames High Prairie (AHP), was grazed but never plowed under private ownership until its acquisition by the Ames School District in 1959.

Although considered for development as a parking lot or football field in the 1960s, the residents of …

An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez Jul 2013

An Ethnographic Study: Becoming A Physics Expert In A Biophysics Research Group, Idaykis Rodriguez

Idaykis Rodriguez

Expertise in physics has been traditionally studied in cognitive science, where physics expertise is understood through the difference between novice and expert problem solving skills. The cognitive perspective of physics experts only create a partial model of physics expertise and does not take into account the development of physics experts in the natural context of research. This dissertation takes a social and cultural perspective of learning through apprenticeship to model the development of physics expertise of physics graduate students in a research group. I use a qualitative methodological approach of an ethnographic case study to observe and video record the …

Degradation Of Algal Palynomorphs On 34-Yr-Old Microscope Slides, Lynn A. Brant Jan 2013

Degradation Of Algal Palynomorphs On 34-Yr-Old Microscope Slides, Lynn A. Brant

Journal of the Iowa Academy of Science: JIAS

Reexamination of 34-yr-old microscope slides of palynological preparations reveals the loss and degradation of algal palynomorphs, in particular the green alga Pediastrum and the desmid Pleurotaenium. Results from this study suggest that great caution should be used when referring co archived palynological slides.


A New Plant Record For Iowa: Lactuca Hirsuta (Asteraceae), Thomas L. Eddy Jan 2013

A New Plant Record For Iowa: Lactuca Hirsuta (Asteraceae), Thomas L. Eddy

Journal of the Iowa Academy of Science: JIAS

A new record of a native vascular plant, Lactuca hirsuta Muhlenberg ex Nuttall var. sanguinea (Bigelow) Fernald, is reported for Iowa. A specimen was collected in 1983 by the author during a study of the Swaledale railroad prairie in Cerro Gordo County, north central Iowa (Eddy 1988). The plant was inexplicably excluded in the species catalogue when a Swaledale railroad flora was published in 1988; thus, this “new” Iowa record in 2013 was collected 30 years prior. The voucher specimen was “re-discovered” by Dr. Neil A. Harriman at the University of Wisconsin-Oshkosh (OSH), and its identification verified.


Smaf: A Soil Health Assessment Tool, D. L. Karlen, C. D. Nance, D. L. Dinnes, D. W. Meek Jan 2013

Smaf: A Soil Health Assessment Tool, D. L. Karlen, C. D. Nance, D. L. Dinnes, D. W. Meek

Journal of the Iowa Academy of Science: JIAS

The Soil Management Assessment Framework (SMAF) was developed to help quantify soil quality/health effects of tillage, crop rotation, and other soil management practices. Our objective was to determine if the SMAF could detect soil health differences after growing a single winter triticale (X Triticosecale Wittmack) crop. Soil samples were collected from 0 to 7.5- and 7.5 to 15- cm depth increments during the 2003 – 2004 and 2004 – 2005 growing seasons near Ames and Lewis, IA, and analyzed for several potential soil quality indicators. The SMAF analysis showed higher soil quality ratings for surface than subsurface samples. It also …

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 2,300 soil …


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 …

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 …

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, the …


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) …

Flood Frequency Estimation By Neyman-Scott Rectangular Pulse Rainfall Model And Topmodel, Richard Bernatz Jan 2011

Flood Frequency Estimation By Neyman-Scott Rectangular Pulse Rainfall Model And Topmodel, Richard Bernatz

Journal of the Iowa Academy of Science: JIAS

A spatial-temporal Neyman-Scott Rectangular Pulse (NSRP) stochastic rainfall model is developed for seasonal-continuous simulation to project annual discharge probabilities from a relatively small watershed, the 1395 km2 Upper Iowa River watershed upstream from Decorah, Iowa. NSRP rainfall data is used as rainfall input to TOPMODEL, a conceptual, semidistributed rainfall runoff model, to calculate river discharge at a site common to the United States Geological Survey (USGS) gauging station in Decorah, Iowa. Annual peak flows based on simulated rainfall are used to fit a log-Pearson type III distribution to project 1 %-, 0.2%-, and 0.1 %-annual discharges. These results are compared …
