Recent Diatoms Reported From The Central United States: Register Of Taxa And Synonyms, Mark E. Eberle Dec 2016

Recent Diatoms Reported From The Central United States: Register Of Taxa And Synonyms, Mark E. Eberle

Biological Sciences Faculty Publications

This list of diatoms summarizes information for more than 1000 taxa and synonyms reported in published accounts of collections made in the central United States, principally within the states of Kansas, Nebraska, and Oklahoma, but also including adjacent areas in eastern Colorado and western Missouri. The objective was to provide people working on diatom projects in this region with a base reference to help them assess the results of their research. Records from Master’s theses and references focused on fossil diatoms were not incorporated into this list. Specimens were not examined, so taxa presented here are those reported in the …


Aquatic Exercise For Better Living On Land: Impact Of Shallow-Water Exercise On Older Japanese Women For Performance Of Activities Of Daily Living (Adl), Mary E. Sanders, Mohammod M. Islam, Aiko Naruse, Nobuo Takeshima, Michael E. Rogers Dec 2016

Aquatic Exercise For Better Living On Land: Impact Of Shallow-Water Exercise On Older Japanese Women For Performance Of Activities Of Daily Living (Adl), Mary E. Sanders, Mohammod M. Islam, Aiko Naruse, Nobuo Takeshima, Michael E. Rogers

International Journal of Aquatic Research and Education

Twenty-six Japanese women (70.5 yr) self-selected water exercise (WEX) (n=13), or control (CON) (n=13) for 12 weeks. WEX was performed 60-minutes/day, 3 days/week with warm-up, cool-down stretch, ADL exercises, and cardiovascular/muscular endurance in 30°C water at a xiphoid level depth. CON continued their current activity/nutrition patterns. Compared to CON, WEX improved (p<.05) functional fitness and balance measures including arm curl (22%), chair stand (21%), 8-feet up & go (13%), chair sit/reach (50%), and 12-min walk (15%). No significant changes in sway velocity (SV) or limits of stability (LOS) were seen for either group. This shallow water exercise improved land-based ADL for older women but not balance. ADL tasks associated with balance did improve which may have indicated enhanced motor control.

Faculty Publications, Biological Sciences

Background Acanthamoebidae is a “family” level amoebozoan group composed of the genera Acanthamoeba, Protacanthamoeba, and very recently Luapeleamoeba. This clade of amoebozoans has received considerable attention from the broader scientific community as Acanthamoeba spp. represent both model organisms and human pathogens. While the classical composition of the group (Acanthamoeba + Protacanthamoeba) has been well accepted due to the morphological and ultrastructural similarities of its members, the Acanthamoebidae has never been highly statistically supported in single gene phylogenetic reconstructions of Amoebozoa either by maximum likelihood (ML) or Bayesian analyses. Results Here we show using a phylogenomic approach that the Acanthamoebidae is …

Natal Host Plants Can Alter Herbivore Competition, Huipeng Pan, Evan L. Preisser, Qi Su, Xiaoguo Jiao, Wen Xie, Shaoli Wang, Qingjun Wu, Youjun Zhang

Biological Sciences Faculty Publications

Interspecific competition between herbivores is widely recognized as an important determinant of community structure. Although researchers have identified a number of factors capable of altering competitive interactions, few studies have addressed the influence of neighboring plant species. If adaptation to/ epigenetic effects of an herbivore's natal host plant alter its performance on other host plants, then interspecific herbivore interactions may play out differently in heterogeneous and homogenous plant communities. We tested wether the natal host plant of a whitefly population affected interactions between the Middleeast Asia Minor 1 (MEAM1) and Mediterranean (MED) cryptic species of the whitefly Bemisia tabaci by …

Cytochrome C Can Form A Well-Defined Binding Pocket For Hydrocarbons, Levi J. Mcclelland, Harmen B. Steele, Frank G. Whitby, Tung-Chung Mou, David Holley, J B. Ross, Stephen R. Sprang, Bruce E. Bowler

Biological Sciences Faculty Publications

Cytochrome c can acquire peroxidase activity when it binds to cardiolipin in mitochondrial membranes. The resulting oxygenation of cardiolipin by cytochrome c provides an early signal for the onset of apoptosis. The structure of this enzyme-substrate complex is a matter of considerable debate. We present three structures at 1.7-2.0 Å resolution of a domain-swapped dimer of yeast iso-1-cytochrome c with the detergents, CYMAL-5, CYMAL-6, and ω-undecylenyl-β-d-maltopyranoside, bound in a channel that places the hydrocarbon moieties of these detergents next to the heme. The heme is poised for peroxidase activity with water bound in place of Met80, which serves as the …

A Slic-Basedsuperpixel Segmentation Method By Using Local Texture Features For Granular Image, Li Xiaoyu, Zhang Qiuju Dec 2016

A Slic-Basedsuperpixel Segmentation Method By Using Local Texture Features For Granular Image, Li Xiaoyu, Zhang Qiuju

Food and Machinery

This paper adopts SLIC-based superpixel segmentation method in the granular image detection. SLIC method segments the granular image into superpixel block which will reduce the complexity of the subsequent image processing. As SLIC superpixel segmentation method doesn’t use the texture feature in the distance calculation, the detail of the outline for the granular object is lost. This paper adopts the CRLBP local texture operator as the texture feature to improve the SLIC segmentation’s distance calculation and searches the similar pixel in circle neighborhood pixels to guarantee the processing speed. The test on cotton seed image shows that the improved SLIC …

An Stm Study On The Structure Of Pt(100)/Ionic Liquid Omipf6 Interface, Jin Peng, Mian-Gang Li, Li-Qiang Xie, Jia-Wei Yan, Bing-Wei Mao

Journal of Electrochemistry

Potential-dependent structures of Pt(100)/ionic liquid 1-methyl-3-octylimidazolium hexafluorophosphate (OMIPF6) interface have been studied by electrochemical scanning tunneling microscopy (ECSTM). The cation OMI+ forms ordered structure on Pt(100) surface, which exists in a potential region of about 1.2 V. When the potential is more negative than -0.6 V, it can be seen that the ordered structure transforms to disordered structure. When the potential shifts positively to +0.6 V, the desorption of cations OMI+ occurs, which indicates that strong electrostatic repulsion is needed to overcome chemical interaction between OMIPF6 and Pt(100) surface, leading to the desorption. The above results …
