Growing Rice Grain With Controlled Cadmium Concentrations, Urszula Kukier, Rufus L. Chaney

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Two solution studies were conducted a) to investigate the uptake of zinc (Zn) and cadmium (Cd) by rice plants (Oryza sativa L.) and interaction between these elements, and b) to determine experimental conditions for growing rice grain with desired Cd concentration for an animal feeding study. In both studies, free metal activities of cadmium and cationic microelements were buffered by an excess of chelating agents. The first study was a factorial design with two Zn levels (1.0 and 3.89 μM) and four Cd levels (0.81, 1.44, 2.56 and 4.55 μM) in the solution. In the second study, rice was …

Use Of Nonsettable Eggs To Evaluate Turkey Hen Fertility, M. R. Bakst, S. Mcgary, I. Estevez, T. Knapp

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The use of nonsettable eggs (checked, cracked) to perform fresh egg breakouts to estimate true fertility and to assess the rate of sperm penetration of the perivitelline layer overlying the germinal disc was evaluated. Germinal discs and the perivitelline layer overlying the germinal disc were accessible for assessments. The stage of blastodermal development positively correlated (r = 0.65, P < 0.0001) with eggshell thickness. It was also determined that the perivitelline layer of nonsettable eggs could be isolated and stained to determine the presence or absence of sperm holes. True fertility of nonsettable eggs (checked and cracked only) and settable eggs was 90 and 95%, respectively. It was concluded that checked and cracked eggs could be used to estimate the true fertility of a flock.

Phenotypic Traits As Reliable Indicators Of Fertility In Male Broiler Breeders, S. Mcgary, I. Estevez, M. R. Bakst, D. L. Pollock

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Genetic selection procedures applied to improve broiler performance may negatively impact the subsequent reproductive efficiency of breeders, particularly in males. Identification of traits that reliably indicate individual male fertility would facilitate selection for reproduction. We hypothesized that physical traits, such as comb area, relative testicular weight, and testicular weight asymmetry, may correlate with fertility in two male-selected primary broiler breeder strains (A and B). Thirty males per strain, individually housed with an average of 10 females, were evaluated at five age periods within the 30-to-50-wk breeding cycle. Flock fertility by candling eggs at Day 19 of incubation and sample fertility …

Mineralization Of N In Swine Manure Amended Soils As A Function Of Soil Temperature, Moisture, And Texture, Brian J. Wienhold, Bahman Eghball

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Manure can serve as an effective fertilizer source if used properly or can lead to environmental contamination if used improperly. Proper use of manure requires some know ledge of the availability of nutrients contained in the manure. To better understand how soil and environmental variables effect N mineralization in manure amended soils a laboratory study was conducted to measure N-mineralization rates as a function of soil texture, water regime, and temperature. This study is part of a national effort to develop a model to predict nutrient availability from various manure sources across a range of soil and environmental conditions. There …

A Personal Account Of Creating The Sterile Insect Technique To Eradicate The Screwworm From Curacao, Florida And The Southeastern United States, Alfred H. Baumhover

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The history is recounted of developing the sterile insect technique to eradicate the screwworm, Cochliomyia hominivorax (Coquerel), from the Caribbean island of Curacao, Florida and the southeastern U.S. Observations of screwworm biology and challenges faced in conducting these eradication projects are described by the author who worked on all aspects of the research and field operations. Eradication was first demonstrated on Curacao, essentially a 170 mi² outdoor laboratory. The population dynamics of the wild screwworm was determined and overflooding ratios and dispersal patterns essential for population suppression were defined. Eradication was achieved with minimal resources by attacking the pest …

Threat Of Foreign Arthropod-Borne Pathogens To Livestock In The United States, Ralph A. Bram, John E. George, Robert E. Reichard, Walter J. Tabachnick

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

There are many exotic animal pathogens throughout the world that, if introduced into the United States, could have a significant detrimental impact on the health of livestock, agricultural economy, the environment, and public health. Many of these pathogens are arthropod-borne and potential vectors are readily available in the United States. A number of these arthropod-borne pathogens are discussed here as examples that illustrate the potential risk and the consequences of inadvertent introductions. Several International agencies have a role in global surveillance and in controlling animal diseases should they begin to expand their range. The risk to the United States is …

Wetlands Replacement Practices And Procedures For Indiana Highway Projects, James E. Alleman, Steve M. Graves

JTRP Technical Reports

It is estimated that Indiana has already lost more than 80% of its original, native wetlands, and concerns have been expressed that some fraction, and perhaps even a sizable fraction, of these losses can be historically linked to highway construction associated with INDOT-related activities. These wetlands are important for several reasons, in that they help keep ground water and surface water clean, serve as reservoirs for floodwaters, help recharge groundwater, provide habitats for many species of animals, and serve as recreational areas. This underlying concern behind this accusation, therefore, is that the construction of state and federal roads historically carried …

Academic Achievement As A Function Of Attributions Of Success And Failure And Socio-Cultural Variables In Mexican-American Students, Mary Alice Reyes

Theses and Dissertations - UTB/UTPA

The purpose of this research was to examine Mexican-American 8th grade students' attributions of success and failure in school-related contexts. The relationship between and among these attributions, socio-cultural variables and academic achievement was also explored and analyzed. Attribution theory formed the theoretical foundation for the study.

The study utilized three instruments as the primary sources of self-reported data: the Texas Assessment of Academic Skills (TAAS ), Student Achievement Responsibility Survey ( SARS ) (Ryckman, 1985), and the Short Acculturation Scale for Hispanic Youth ( SASH-Y ) (Barona & Miller, 1994). Other data including gender and migrant status were obtained from …

When Legislatures Delegate Death: The Troubling Paradox Behind State Uses Of Electocution And Lethal Injection And What It Says About Us, Deborah W. Denno

Faculty Scholarship

This article discusses the paradoxical motivations and problems behind legislative changes from one method of execution to the next, and particularly moves from electrocution to lethal injection. This article first examines the constitutionality of electrocution, contending that a modern Eighth Amendment analysis of a range of factors, such as legislative trends toward lethal injection, indicates that electrocution is cruel and unusual. It then provides an Eighth Amendment review of lethal injection, demonstrating that injection also involves unnecessary pain, the risk of such pain, and a loss of dignity. The article next presents the author's study of the most current protocols …

A Look At Crab Monitoring In The Elkhorn Slough, Jennifer Everly

Capstone Projects and Master's Theses

Crabs play an important role in Elkhorn Slough. The three main species found in the slough, that are native to it, and that I will be looking at are Pachygrapsus crassipes, the striped shore crab, Hemigrapsus oregonensis, the yellow shore crab, and Cancer antennarius, the Pacific Rock Crab. There is one non native species of crab that is found in the slough, the European green crab, Carcinus maenas. Not much is known about the population sizes of any of these four crab species. The goal of my project was to create and implement a long term monitoring program that could …

The Effect Of Toxic Microcystis Aeruginosa On Four Different Populations Of Daphnia, Melanie L. Blanchette, James F. Haney

Center for Freshwater Biology

Cyanobacteria reduce the fitness of many Daphnia species, and blooms in eutrophic lakes may place strong selective pressure upon these primary consumers. This study examines the ability of daphnids to resist the deleterious effects of toxic Microcystis and determine if this resistance is related to the trophic conditions of their native lakes. Three populations of Daphnia pulex/pulicaria were examined; D. pulicaria from eutrophic Klamath Lake in Oregon, D. pulex from eutrophic Old Durham Reservoir in New Hampshire, and D. pulicaria from oligotrophic Russell Pond in New Hampshire. D. carinata from meso-oligotrophic Lake Rotoaira in New Zealand was used as a …

Theistic Activism And The Euthyphro Dilemma, David Baggett

Faculty Dissertations

My dissertation focuses on the Euthyphro question, from one of the Socratic dialogues, understood in terms of the following dilemma posed against theistic ethics: (1) Either what is good/right is moral because God commands it, or it is not. (2) If what is good/right is moral because God commands it, then the good/right is arbitrary and vacuous. (3) If what is good/right is moral for reasons other than that God commands it, then God is superfluous from the standpoint of morality. (4) So, either the good/right is arbitrary and vacuous or God is superfluous to morality.

The dilemma is really …
