General Isochronous Rhythm In Echolocation Calls And Social Vocalizations Of The BatSaccopteryx Bilineata, Lara S. Burchardt, Philipp Norton, Oliver Behr, Constance Scharff, Mirjam Knörnschild Jan 2019

General Isochronous Rhythm In Echolocation Calls And Social Vocalizations Of The BatSaccopteryx Bilineata, Lara S. Burchardt, Philipp Norton, Oliver Behr, Constance Scharff, Mirjam Knörnschild

KIP Articles

Rhythm is an essential component of human speech and music but very little is known about its evolutionary origin and its distribution in animal vocalizations. We found a regular rhythm in three multisyllabic vocalization types (echolocation call sequences, male territorial songs and pup isolation calls) of the neotropical bat Saccopteryx bilineata . The intervals between element onsets were used to fit the rhythm for each individual. For echolocation call sequences, we expected rhythm frequencies around 6–24 Hz, corresponding to the wingbeat in S. bilineata which is strongly coupled to echolocation calls during flight. Surprisingly, we found rhythm frequencies between 6 …

Phytochemical Investigation And Drug Interaction Potential Of Cyanotis Vaga, Ibrahim Almarabi Jan 2019

Phytochemical Investigation And Drug Interaction Potential Of Cyanotis Vaga, Ibrahim Almarabi

Electronic Theses and Dissertations

Cyanotis. vaga (Lour.) Schult, & Schult. f. (C. vaga) previously called Tradescantia vaga and Cyanotis barbata, is a perennial herb. It is native to Eastern Asia and Tropical Africa. It has been reported that its decoction reduces fever and enhances well-being. Recently, C. vaga has been used widely for its anabolic effects, due to its richness of ecdysteroids. Even though C. vaga is a commedicinal plant (dietary supplement), there are no reports about its effect on the drug metabolizing enzyme Cytochromes P450 to predict its interaction with concomitantly used medications. In this study, eight ecdysteroids were isolated …

"Remember Me, In Your Stories And In Your Songs": The Magical Journey To Celtic Cultural Resurrection And The Re-Discovery Of Self In Song Of The Sea, Wisarut Painark

Manusya, Journal of Humanities

This study examines the deployment of magical realism along with cinematic techniques in Song of the Sea. Analysing the animated film as a cultural text in light of magical realism, it argues that the film intermingles two different worlds, the mundane and the fantastic, to provide audiences with a more inclusive view of reality. The existence of Celtic mythical beings, selkies, brought to life by magical realism, becomes the cornerstone in the protagonists' healing process as their interactions with these mythical beings gradually reshape their conception of reality. A new "reality" is, thus, employed to vex the protagonists' mind and …

Development Of A Biosafety Level-2 Facility For Irradiation Of Biological Cells Using Mev Ions, Jay D. Diaz, Naresh T. Deoli, Deborah Rogers, Armin De Vera, Karen M. Smith, Robin Schmeider-Broussard, Harry J. Whitlow

Louisiana Accelerator Center

The development of a facility for irradiation of murice and primate tissue presents several challenges. First, extremely low fluences (10⁶-10¹¹ ions cm⁻²) are required to deliver doses of 1 mGy - 50 Gy using MeV proton. Second,the tissues, particularly from non-human primate, may be infectious to humans. Third, protection of irradiated tissue samples from contamination by mold and bacteria is critical. Here we present an ultra-low flux irradiation facility and associated fluence control for biological cell and tissue irradiation under sterile biosafety level 2 (BSL-2) conditions suitable for use with low energy (1-3.4 MeV) protons. The operation is demonstrated using …

Lighting The Way: The Johnson Amendment Stands Strong Against Dark Money In Politics, Whitney Untiedt Jan 2019

Lighting The Way: The Johnson Amendment Stands Strong Against Dark Money In Politics, Whitney Untiedt

Emory Business Law Review

Wrapping itself in the cloak of 'religious freedom,' the current administration, supported by many conservative members of Congress, has overtly pursued repeal of the Johnson Amendment, an oft-cited clause in the Internal Revenue Code that prohibits certain nonprofit organizations from endorsing political candidates or making campaign contributions. The consequences of deregulating the prohibition on tax-deductible political donations could imperil our country's traditions of electoral process.


Effects Of Grazing And Fire On Soil Microbial Communities And Hydrological Processes In The Northern Great Plains Grassland, Jacob Comer Jan 2019

Effects Of Grazing And Fire On Soil Microbial Communities And Hydrological Processes In The Northern Great Plains Grassland, Jacob Comer

Electronic Theses and Dissertations

Historic grazing and fire regimes have been altered with the development of the livestock industry in the Northern Great Plains and have resulted in a reduction of diversity across all scales. As alternative land surface disturbances are developed to combat the loss of diversity, their potential to serve as a sustainable land surface disturbance should be evaluated. To determine the ability of an alternative grazing strategy to serve as a sustainable land surface disturbance, the reaction of the soil microbial community and soil hydrological processes should be evaluated. Objectives of this study were to: 1) evaluate the impact of alternative …

The Tortoise (Wildfire) And The Hare (Heavy Winter Grazing) For Promoting Heterogeneity And Improving Ecosystem Services, Lucas W. Zilverberg Jan 2019

The Tortoise (Wildfire) And The Hare (Heavy Winter Grazing) For Promoting Heterogeneity And Improving Ecosystem Services, Lucas W. Zilverberg

Electronic Theses and Dissertations

The Northern Great Plains (NGP) mixed-grass prairie developed under fire, grazing, and periodic droughts, which created a heterogeneous landscape. Since European settlement, heterogeneous landscapes have declined due to fire suppression and the maximization of livestock production, leading to the need for an alternative management practice. Our overall project objective was to determine if heavy winter grazing could be used as an alternative to patch-burn grazing for promoting heterogeneity and improving ecosystem services in the NGP. Fire has been used very effectively in patch-burn grazing management to create heterogeneity in pastures in some areas, however burning is not readily adopted in …


The Effect Of Edge-Of-Field Nutrient Management Practices On Microbial Concentrations In Subsurface Drainage Water And The Associated Risk Of Antibiotic Resistance Dissemination, Sara Mardani Jan 2019

The Effect Of Edge-Of-Field Nutrient Management Practices On Microbial Concentrations In Subsurface Drainage Water And The Associated Risk Of Antibiotic Resistance Dissemination, Sara Mardani

Electronic Theses and Dissertations

Many in-field and edge-of-field management practices have been used to reduce nutrient loads from agricultural fields. The denitrification woodchip bioreactor (WB) is one edgeof- field management practice that has proven to be effective in removing nitrate from subsurface drainage water. The success in nitrate removal achieved with WBs has raised interest in expanding their capabilities for removing other agricultural pollutants, including phosphorus, by using other types of media like phosphorus-sorbing filters or combining these filters with woodchips to remove both nitrate and phosphorus as dual-nutrient removal systems. Despite the extensive research done on WBs and nutrient filter materials, little consideration …

Optimization Of Canola Co-Product Utilization In Swine, Jung Wook Lee Jan 2019

Optimization Of Canola Co-Product Utilization In Swine, Jung Wook Lee

Electronic Theses and Dissertations

Canola co-products have a high content of fiber and glucosinolates. Fiber reduces nutrient utilization in pigs, whereas glucosinolates are degraded to toxic products, which interfere with liver, kidney and thyroid functions. Negative effects of fiber can potentially be alleviated by fiber-degrading enzymes, whereas negative effects of glucosinolates in pigs can potentially be alleviated through reduction in hindgut pH. However, there is a lack of information on effects of supplemental fiberdegrading enzymes on digestion and fermentation characteristics of canola coproducts for pigs. Also, there is limited information on effects of reducing hindgut pH on toxicity of glucosinolates in pigs. Four experiments …

The rising awareness of chemical activities created immense need for sustainable development schemes and strategies that should address the environmental impact without compromising the yield. In the course of developing green extraction techniques, automation, alternative solvents, and selective extractions are the growing trend. This dissertation aligns with that progress by surveying green solvents, comparing their performance during oil extraction, examining a …


Direct And Indirect Effects Of Recent Gizzard Shad Introductions In Four South Dakota Small Impoundments, Brandon Vanderbush Jan 2019

Direct And Indirect Effects Of Recent Gizzard Shad Introductions In Four South Dakota Small Impoundments, Brandon Vanderbush

Electronic Theses and Dissertations

Managing fisheries requires balancing predators and prey. Prey stockings are often used when food sources may be limiting to support fish communities with multiple predators. Stocking of prey often results in increased predator size and could potentially lead to the consumption of nuisance species such as Black Bullheads Ameiurus melas. Gizzard Shad Dorosoma cepedianum are an often-stocked prey species and have been recently stocked into several small impoundments across South Dakota. One of the focuses of this study was to document the contribution of age-0 Gizzard Shad to predator fish food habits and growth. Gizzard Shad consumption varied between …


Abundance And Diversity Of Grasshoppers And Their Ectoparasitic Mites In South Dakota, Erica Anderson Jan 2019

Abundance And Diversity Of Grasshoppers And Their Ectoparasitic Mites In South Dakota, Erica Anderson

Electronic Theses and Dissertations

In South Dakota, grasshoppers (Orthoptera: Acrididae) are sporadic pests that can cause economic injury to rangeland and crops during outbreaks. It is important to know which grasshopper species are present as not all have the same potential to cause damage. USDA-APHIS conducts annual grasshopper surveys in western South Dakota rangelands, but the last published survey was in 1925. Of the potential biological control agents existing, grasshopper mites feed on grasshopper eggs and the larvae are ectoparasites of nymph and adult grasshoppers. Previous studies suggest that mite larvae reduce grasshopper fecundity and mobility, making them useful for integrated pest management of …

Tropical Forest Canopy Height And Aboveground Biomass Estimation Using Airborne Lidar And Landsat-8 Data, A Sensitivity Study With Respect To Landsat-8 Data Temporal Availability, In Mai Ndombe Province, Democratic Republic Of Congo, Herve B. Kashongwe

Electronic Theses and Dissertations

Tropical forests’ structure information, such as forest canopy height, is a key component in any estimate of carbon stock. Tropical rainforests constitute the most forested ecosystems that harbor the largest biodiversity on Earth and store more carbon (above and belowground biomass) than any other ecosystem in the world. However, estimates of forest canopy structure is lacking over most of the regions that host this ecosystem because of both the structure’s complexity of this ecosystems and the incomplete or lack of up-to-date national forest inventory data necessary to derive forest canopy height and aboveground biomass. This study explores the capability of …
