Cosmological Beliefs About Origins Related To Science Achievement Among Junior High-School Students In South Bend, Indiana, J David Van Dyke 2010 Andrews University

Cosmological Beliefs About Origins Related To Science Achievement Among Junior High-School Students In South Bend, Indiana, J David Van Dyke

Dissertations

Problem. American high-school students score lower in science achievement tests than their peers in other developed nations. The Organization for Economic Cooperation and Development (OECD) ranked the scientific achievement of American high-school students as ―very low‖ in comparison to high-school students in other industrialized nations—only 29th out of 57 developed countries. Research has indicated that achievement declines as U.S. students progress to higher grades and take on more rigorous science courses. A variety of factors have been documented that may account for U.S. students‘ lower science achievement rankings. These include socioeconomic status, race, and gender. One area ...

Maria Sibylla Merian's Frogs, Kay Etheridge 2010 Gettysburg College

Maria Sibylla Merian's Frogs, Kay Etheridge

Biology Faculty Publications

Maria Sibylla Merian (German, 1647-1717) is best known for her magnificent 1705 publication, Metamorphosis insectorum surinamensium, although she published earlier works on insect metamorphosis. Merian wrote the text and painted all of the illustrations for her books, and for the early volumes she produced most of the engravings. Contemporary scholarship has focused primarily on Merian's detailed images of lepidopteran and host plant life cycles, but Merian's Surinam album also portrays anuram metamorphosis, including the first European depiction of Pipa pipa.


Dependency On De Novo Protein Synthesis And Proteomic Changes During Metamorphosis Of The Marine Bryozoan Bugula Neritina, Yue Him Wong, Shawn M. Arellano, Huoming Zhang, Timothy Ravasi, Pei-Yuan Qian 2010 Western Washington University

Dependency On De Novo Protein Synthesis And Proteomic Changes During Metamorphosis Of The Marine Bryozoan Bugula Neritina, Yue Him Wong, Shawn M. Arellano, Huoming Zhang, Timothy Ravasi, Pei-Yuan Qian

Shannon Point Marine Center Faculty Publications

Background: Metamorphosis in the bryozoan Bugula neritina (Linne) includes an initial phase of rapid morphological rearrangement followed by a gradual phase of morphogenesis. We hypothesized that the first phase may be independent of de novo synthesis of proteins and, instead, involves post-translational modifications of existing proteins, providing a simple mechanism to quickly initiate metamorphosis. To test our hypothesis, we challenged B. neritina larvae with transcription and translation inhibitors. Furthermore, we employed 2D gel electrophoresis to characterize changes in the phosphoproteome and proteome during early metamorphosis. Differentially expressed proteins were identified by liquid chromatography tandem mass spectrometry and their gene expression ...


Two Novel Approaches Used To Produce Biodiesel From Low-Cost Feedstocks, Xiaohu Fan, Xi Wang, Feng Chen 2010 Clemson University

Two Novel Approaches Used To Produce Biodiesel From Low-Cost Feedstocks, Xiaohu Fan, Xi Wang, Feng Chen

Publications

The price of feedstock is one of the most significant factors affecting the economic viability of biodiesel manufacturer. Many approaches were investigated to reduce the biodiesel production cost. The present work gave a preliminary study of two approaches to economically produce biodiesel from waste cooking oil (WCO) and flaked cottonseed. One was the use of ultrasound-assisted synthesis of biodiesel from WCO. The other was the application of in situ transesterification from flaked cottonseed. Gas chromatography (GC) and High performance liquid chromatography (HPLC) results demonstrated the feasibility of using both approaches to produce biodiesel from low-cost feedstock.

Publications

Harvested longan (Dimocarpus longan Lour.) fruit are susceptible to decay caused by both bacterial and fungal infections. Ochratoxin A (OTA) is a kind of mycotoxin produced by a number of fungi. In this study, OTA was extracted from longan fruit pulp by 80% methanol and then loaded on C-18 solid-phase extraction columns. The extract solution was then analyzed by high-performance liquid chromatography - fluorescence detection (HPLC-FD) and an electron spray ionization-mass spectrometry (ESI-MS), respectively. The HPLC-FD analysis showed that a compound similar to OTA might exist in longan fruit pulp, but further analysis by the ESI-MS method demonstrated that OTA was ...

Phosphorus For High Rainfall Pastures, Mike Bolland, Bill Russell, David Weaver 2010 Department of Agriculture and Food, Western Australia

Phosphorus For High Rainfall Pastures, Mike Bolland, Bill Russell, David Weaver

Bulletins 4000 -

Soil testing for phosphorus provides a reliable indication of when the level of phosphorus in a soil is likely to be adequate for pasture production in the next growing season. It is a waste of money to apply phosphorus fertiliser when soil testing indicates none is required, or to acidified soils, or to undergrazed pastures, or to pastures dominated by poorly productive species.

Legumes have higher phosphorus requirement than grasses.

Critical soil test phosphorus values do not change when nitrogen fertiliser is applied.


Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell 2010 Department of Agriculture and Food, Western Australia

Potassium For High Rainfall Pastures, Mike Bolland, Bill Russell

Bulletins 4000 -

Potassium plays a major role in plant growth. It maintains the solutions in plant cells at ionic strengths suitable for maintaining strong plant walls and for the proper functioning of leaf pores (stomata) and plant processes such as photosynthesis, transport of sugars and enzyme activation.

Potassium does not become a direct part of the plant structure but acts to regulate water balances, nutrient and sugar movement in plant tissue. Plants deficient in potassium cannot use other nutrients and water efficiently. They are less tolerant of stresses such as drought and waterlogging and are more susceptible to pests and diseases.


Riparian Conundra, David Weaver 2010 Department of Agriculture and Food, Western Australia

Riparian Conundra, David Weaver

Conference papers and presentations

Riparian vegetation is established or restored on the basis that it physically filters and traps hillslope derived particulate nutrients in surface runoff. Whilst many studies support this conventional model of riparian function, few test this models embedded assumptions. The assumptions are that catchments are surface runoff dominated, that most surface derived nutrients are transported in particulate form, and that riparian management targets locations that will result in the greatest change in water quality. This paper reviews studies in south west Western Australia that challenge these assumptions. Plots measuring leaching and runoff of nutrients showed that 20 times more water and ...

Bat Habitat Use And Roost Tree Selection For Northern Long-Eared Myotis (Myotis Septentrionalis) In North-Central Ohio, Timothy J. Krynak

Masters Theses

Understanding roosting behavior and habitat use of bats is an important component when unraveling life histories and their ecology. Ohio remains under-represented in published information of bats compared to surrounding states. This large scale survey in 2002–2003 and Myotis septentrionalis radio telemetry study in 2005 is one of the few conducted within the state and is the first in Ohio’s North-Central region. It is also the first study conducted where net sites were chosen randomly and spatially distributed to adequately survey bat populations within Cuyahoga Valley National Park and Cleveland Metroparks. This survey documented seven species (n = 668 ...

Increased Perfusion And Angiogenesis In A Hindlimb Ischemia Model With Plasmid Fgf-2 Delivered By Noninvasive Electroporation, B. Ferraro, Y. L. Cruz, M. Baldwin, D. Coppola, R. Heller

Bioelectrics Publications

Gene therapy approaches delivering fibroblast growth factor-2 (FGF-2) have shown promise as a potential treatment for increasing blood flow to ischemic limbs. Currently, effective noninvasive techniques to deliver plasmids encoding genes of therapeutic interest, such as FGF-2, are limited. We sought to determine if intradermal injection of plasmid DNA encoding FGF-2 (pFGF) followed by noninvasive cutaneous electroporation (pFGFE+) could increase blood flow and angiogenesis in a rat model of hindlimb ischemia. pFGFE+ or control treatments were administered on postoperative day 0. Compared to injection of pFGF alone (pFGFE-), delivery of pFGFE+ significantly increased FGF-2 expression for 10 days. Further, the ...


Shorebird Migration In Western Kentucky: Phenology, Habitat Use, And Possible Effects Of Prey Availability, Nicole Ann Ranalli 2010 Eastern Kentucky University

Shorebird Migration In Western Kentucky: Phenology, Habitat Use, And Possible Effects Of Prey Availability, Nicole Ann Ranalli

Online Theses and Dissertations

Staging areas along the coasts provide reliable food resources and shorebirds may use the same stopover locations every year. However, shorebirds use sites opportunistically in the interior of North America due to the transient nature of many habitats. Little is known, however, about the use of wetlands by migrating shorebirds in Kentucky. During 2004 and 2005, I examined the phenology of migration and habitat use of shorebirds using stopover habitats in Kentucky, and also examined possible relationships between prey availability and habitat selection by migrating shorebirds. To mitigate wetland loss, the Kentucky Department of Fish and Wildlife Resources (KDFWR) constructed ...


Electric Pulses To Prepare Feeder Cells For Sustaining And Culturing Of Undifferentiated Embryonic Stem Cells, Lauren M. Browning, Tao Huang, Xiao-Hong Nancy Xu 2010 Old Dominion University

Electric Pulses To Prepare Feeder Cells For Sustaining And Culturing Of Undifferentiated Embryonic Stem Cells, Lauren M. Browning, Tao Huang, Xiao-Hong Nancy Xu

Chemistry & Biochemistry Faculty Publications

Current challenges in embryonic-stem-cell (ESC) research include inability of sustaining and culturing of undifferentiated ESCs over time. Growth-arrested feeder cells are essential to the culture and sustaining of undifferentiated ESCs, and they are currently prepared using gammaradiation and chemical inactivation. Both techniques have severe limitations. In this study, we developed a new, simple and effective technique (pulsed-electric-fields, PEFs) to produce viable growth-arrested cells (RTS34st) and used them as high-quality feeder cells to culture and sustain undifferentiated zebrafish ESCs over time. The cells were exposed to 25 sequential 10- nanosecond-electric-pulses (10nsEPs) of 25, 40 and 150 kV/cm with 1s pulse ...

Effect Of Different Resistance Exercise Repetition Velocities On Excess Post-Exercise Oxygen Consumption And Energetic Expenditure, Ana Critine Barreto, Alex Souto Maior, Pedro Menzes, Jeffrey Willardson, Antonio Jose Silva, Victor Machado Reis, Roberto Simão, Jefferson Novaes

Jeffrey Willardson

The excess post-exercise oxygen consumption (EPOC) consists of the excess oxygen consumed above a resting state following exercise. Performance of resistance exercise can significantly disrupt the body’s homeostasis, with the EPOC being dependent on the specific combination of prescriptive variables. Presently, the effects of different repetition velocities on VO2 and caloric expenditure during and following resistance exercise bouts have not been completely elucidated. Objective: To examine the effect of different repetition velocities on EPOC and total energetic expenditure during and following resistance exercise bouts. Methods: Twenty women (34.6 ± 5.5 years; 159 ± 4.1 cm; 55.1 ± 3 ...

Barley Variety Trial Report, Heather Darby, Susan Monahan, Erica Cummings, Rosalie Madden, Amanda Gervais, Philip Halteman

Northwest Crops & Soils Program

There has been increasing interest in growing barley (Hordeum vulgare L.) for malting in Vermont and throughout New England to provide local grains for craft breweries and distilleries. Malting barley must meet specific quality characteristics such as high germination and low protein content. Both two-row and six-row barley can be used for malting, depending on the brewer’s preferences. The goal of this project was to evaluate yield and quality of publicly available malting barley varieties.

Sunflower Variety Trial Report, Heather Darby, Philip Halteman, Erica Cummings, Amanda Gervais, Rosalie Madden

Northwest Crops & Soils Program

Variety selection is one of the most important agronomic decisions that sunflower growers make about their crop each season, especially in Vermont where the relatively short growing season limits available choices. Sticking with a tried and true variety is often difficult because new varieties are released every year while familiar ones are discontinued, and seed companies release new traits that may or may not influence yield. To help area farmers make the best decisions, UVM Extension conducted replicated variety trials at Borderview Reseach Farm in Alburgh, VT during the 2010-growing season. The trial evaluated fourteen varieties with varying maturity dates ...
