Biofield And Fungicide Seed Treatment Influences On Soybean Productivity, Seed Quality And Weed Community, A.W. Lenssen Dec 2012

Biofield And Fungicide Seed Treatment Influences On Soybean Productivity, Seed Quality And Weed Community, A.W. Lenssen

Mahendra Kumar Trivedi

Soybean production in Iowa USA is among the most productive for rainfed regions in the world. Despite generally having excellent soils, growing season temperatures and rainfall, soybean yields are decreased by weed interference and inadequate available soil water at key stages of crop development. A field study was conducted at two locations in Iowa in 2012 to determine if seed-applied fungicide or biofield treatments influenced weed community, soil volumetric water concentration and soybean yield and quality. Application of biofield treatment resulted in lower density of tall waterhemp density, greater soybean stand density at R8 stage and greater seed pod–1 compared …

The 2008 Crisis From The Neurofinance Perspective: Investor Humor And Market Sentiment, Armando F. Rocha Dec 2012

The 2008 Crisis From The Neurofinance Perspective: Investor Humor And Market Sentiment, Armando F. Rocha

Armando F Rocha

The world is still facing a financial crisis that started in mid 2007 and up to moment it is unsolved. Stock markets around the world reacted badly and the real time news has never played such an important role to investors as seen in previous crises. The impact of the media deepened the bear dynamics of markets around the world amplifying their volatility. Neurofinances is a new field of inquiring that has the purpose of studying decision making taking into consideration the role played by emotion. Here, we use these notions to develop a neurofinance modelling of the Brazilian stock …


Comparative Genome Analysis Of Spiroplasma Melliferum Ipmb4a, A Honeybee-Associated Bacterium, Wen-Sui Lo, Ling-Ling Chen, Wan-Chia Chung, Gail E. Gasparich, Chih-Horng Kuo Dec 2012

Comparative Genome Analysis Of Spiroplasma Melliferum Ipmb4a, A Honeybee-Associated Bacterium, Wen-Sui Lo, Ling-Ling Chen, Wan-Chia Chung, Gail E. Gasparich, Chih-Horng Kuo

Gail Gasparich

Background: The genus Spiroplasma contains a group of helical, motile, and wall-less bacteria in the class
Mollicutes. Similar to other members of this class, such as the animal-pathogenic Mycoplasma and the
plant-pathogenic ‘Candidatus Phytoplasma’, all characterized Spiroplasma species were found to be associated with
eukaryotic hosts. While most of the Spiroplasma species appeared to be harmless commensals of insects, a small
number of species have evolved pathogenicity toward various arthropods and plants. In this study, we isolated a
novel strain of honeybee-associated S. melliferum and investigated its genetic composition and evolutionary history
by whole-genome shotgun sequencing and comparative analysis with …

Master Mentor: Robert Schuellein '44 Leaves A Lasting Impression, Maureen E. Schlangen Dec 2012

Master Mentor: Robert Schuellein '44 Leaves A Lasting Impression, Maureen E. Schlangen

Maureen E. Schlangen

Robert Schuellein left the University of Dayton for the National Institutes of Health in 1963. But he never forgot UD and the legacy he started here: With his faculty colleague and fellow Marianist Paul Machowicz ’41, Schuellein helped create the first master’s program in the College of Arts and Sciences. When Schuellein died in 2011 at the age of 91, he added to that legacy — with a bequest totaling $2.5 million for a faculty research endowment in biology.


The Type Localities Of The Mule Deer, Odocoileus Hemionus (Rafinesque, 1817), And The Kansas White-Tailed Deer, Odocoileus Virginianus Macrourus (Rafinesque, 1817), Are Not Where We Thought They, Neal Woodman Dec 2012

The Type Localities Of The Mule Deer, Odocoileus Hemionus (Rafinesque, 1817), And The Kansas White-Tailed Deer, Odocoileus Virginianus Macrourus (Rafinesque, 1817), Are Not Where We Thought They, Neal Woodman

Neal Woodman

Among the iconic mammals of the North American West is the mule deer (Odocoileus hemionus). This species and a western subspecies of the white-tailed deer (Odocoileus virginianus macrourus) were two of seven mammals originally named and described as new species in 1817 by Constantine S. Rafinesque. Rafinesque never saw the animals that he named. Instead, he followed the then-acceptable practice of basing his new species on animals characterized in another published work, in this case the putative journal of Charles Le Raye, a French Canadian fur trader who was said to have traversed the upper Missouri River region before the …


Morphological Distinctiveness Of Javan Tupaia Hypochrysa (Scandentia, Tupaiidae), Eric J. Sargis, Neal Woodman, Natalie Morningstar, Aspen Reese, Link E. Olson Dec 2012

Morphological Distinctiveness Of Javan Tupaia Hypochrysa (Scandentia, Tupaiidae), Eric J. Sargis, Neal Woodman, Natalie Morningstar, Aspen Reese, Link E. Olson

Neal Woodman

The common treeshrew, Tupaia glis, represents a species complex with a complicated taxonomic history. It is distributed mostly south of the Isthmus of Kra on the Malay Peninsula and surrounding islands. In our recent revision of a portion of this species complex, we did not fully assess the population from Java (T. ‘‘glis’’ hypochrysa) because of our limited sample. Herein, we revisit this taxon using multivariate analyses in comparisons with T. glis, T. chrysogaster of the Mentawai Islands, and T. ferruginea from Sumatra. Analyses of both the manus and skull of Javan T. ‘‘glis’’ hypochrysa show it to be most …

Varying-Smoother Models For Functional Responses, Philip T. Reiss, Lei Huang, Huaihou Chen, Stan Colcombe Dec 2012

Varying-Smoother Models For Functional Responses, Philip T. Reiss, Lei Huang, Huaihou Chen, Stan Colcombe

Philip T. Reiss

This paper studies estimation of a smooth function f(x,v) when we are given functional responses of the form f(x, ·) + error, but scientific interest centers on the collection of functions f(·,v) for different v. The motivation comes from studies of human brain development, in which x denotes age whereas v refers to brain locations. Analogously to varying-coefficient models, in which the mean response is linear in x, the “varying-smoother” models that we consider exhibit nonlinear dependence on x that varies smoothly with v. We discuss three approaches to estimating varying-smoother models: (a) methods that employ a tensor product penalty; …

A Critical Examination Of Food Technology, Innovation And Teacher Education : A Technacy Genre Theory Perspective, Angela Frances Turner Dec 2012

A Critical Examination Of Food Technology, Innovation And Teacher Education : A Technacy Genre Theory Perspective, Angela Frances Turner

Dr Angela Turner

There are many and varied forces that shape food technology curriculum, but two that emerge as significant and of specific interest to this research are the perceptions of food technology education and economic trends that influence food technology. The broad goal was to examine the extent to which food technology in secondary schooling is well placed to meet emerging policy and economic demand for food innovation expertise in the industry. With both the school sector and the professional sector each asserting that their respective perceptions of Food Technology was correct, a method for clarifying and classifying the nature of the …

An Assessment Of Fecal Indicator And Other Bacteria From An Urbanized Coastal Lagoon In The City Of Los Angeles, California, Usa., Victor D. Carmona Dec 2012

An Assessment Of Fecal Indicator And Other Bacteria From An Urbanized Coastal Lagoon In The City Of Los Angeles, California, Usa., Victor D. Carmona

Victor D. Carmona-Galindo

A study was performed in Del Rey Lagoon, City of Los Angeles, to determine if the lagoon was as a source or sink for fecal indicator bacteria (FIB: total coliforms, Escherichia coli, enterococci) and to screen for the presence of other potentially pathogenic bacteria. The lagoon receives tidal flows from the adjacent Ballona Estuary whose water usually is contaminated with FIB originating from the highly urbanized Ballona Creek Watershed. During 16 sampling events from February 2008 through March 2009, replicate water samples (n = 3) were collected 1 h prior to the high tide and 1 h prior to the …


The Impact Of Invasive Species Management Strategies On The Population Dynamics Of Castor Bean (Ricinus Communis L., Euphorbiaceae) At Two Southern California Costal Habitats, Victor D. Carmona Dec 2012

The Impact Of Invasive Species Management Strategies On The Population Dynamics Of Castor Bean (Ricinus Communis L., Euphorbiaceae) At Two Southern California Costal Habitats, Victor D. Carmona

Victor D. Carmona-Galindo

The diverse uses of Ricinus communis L. (Castor bean) in herbalism, agriculture, and horticulture have facilitated the worldwide dispersal of this r-selected species. Management strategies to eradicate R. communis in southern California have largely relied on manual labor, which in turn is limited by budget. This study assesses how two different invasive species management strategies in southern California impact the survivorship and fecundity of naturalized R. communis populations. Our findings suggest that documenting patterns of survival and reproduction serve as a tool for the adaptive management of invasive species eradication efforts.


Cycling Of The Signaling Protein Phospholipase D Through Cilia Requires The Bbsome Only For The Export Phase, Jason Brown Dec 2012

Cycling Of The Signaling Protein Phospholipase D Through Cilia Requires The Bbsome Only For The Export Phase, Jason Brown

Jason Brown

The BBSome is a complex of seven proteins, including BBS4, that is cycled through cilia by intraflagellar transport (IFT). Previous work has shown that the membrane-associated signaling protein phospholipase D (PLD) accumulates abnormally in cilia of Chlamydomonas reinhardtii bbs mutants. Here we show that PLD is a component of wild-type cilia but is enriched ∼150-fold in bbs4 cilia; this accumulation occurs progressively over time and results in altered ciliary lipid composition. When wild-type BBSomes were introduced into bbs cells, PLD was rapidly removed from the mutant cilia, indicating the presence of an efficient BBSome-dependent mechanism for exporting ciliary PLD. This …
