Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, Richard Ramsundar 2015 Fordham University

Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, Richard Ramsundar

Student Theses 2015-Present

This thesis compares and explains the advantages aquaponics farming has over modern industrial intensive farming. Through a comparison natural capital usage, conservation, recycling and cost, the thesis advocates for the expansion of aquaponics usage in urban settings. The thesis also explains the history of intensive farming and aquaponics in America, the science of how aquaponics operates, the economic and environmental costs of modern intensive farming versus aquaponics farming, and the social implications of aquaponics. Lastly, I propose a policy that reallocates farm subsidies by modifying the Farm Bill. Then I propose policies that support creating a new standard of farm ...


Characterization Of A Novel Clade Of Transporters In Phytophthora, Stephanie Padula, Paul F. Morris Dr, Howard Casey Cromwell Dr., Menaka Ariyaratne, Andrew Wagner 2015 Bowling Green State University - Main Campus

Characterization Of A Novel Clade Of Transporters In Phytophthora, Stephanie Padula, Paul F. Morris Dr, Howard Casey Cromwell Dr., Menaka Ariyaratne, Andrew Wagner

Honors Projects

The oomycete Phytophthora parasitica has a worldwide distribution and is an economically important pathogen of more than 100 species4. RNA-seq analysis showed that one gene, PPTG_16698 has the 5th highest level of expression of all transport proteins in the zoospore stage, and is highly conserved throughout Phytophthora species. This project attempts to characterize the important biological role that PPTG_16698 plays in P. parasitica and other oomycetes. Three strategies have been implemented to accomplish this goal: growth analysis by heterologous expression in yeast, metabolite analysis in yeast, and construction of a GFP fusion protein to enable localization of the ...


Accessing Chilling Conditions For Perennial Fruit Crop Production In Kentucky, Yao Xue 2015 Western Kentucky University

Accessing Chilling Conditions For Perennial Fruit Crop Production In Kentucky, Yao Xue

Masters Theses & Specialist Projects

Temperate Region fruit and nut trees, and many other perennial plants, require cool winter temperatures (chilling hours) to ensure leaf and flower bud production in the following season. Temperate Regions are characterized by variable winter and spring temperatures. Failure of meeting sufficient chilling requirement results in deformed fruits, unequal maturation, and other plant deformities, thereby reducing quality and yields. Chilling requirements are expressed as number of accumulated hours within a range of approximately 32º to 45ºF or 0º to 7.2ºC. These requirements are specific for level of temperature, length of temperature period, and species and cultivar of plants. Information ...


Impact Of Wet Distillers Grains Plus Solubles And Antioxidants On A Basic Mechanism Of Beef Tenderization, Michael D. Chao 2015 University of Nebraska-Lincoln

Impact Of Wet Distillers Grains Plus Solubles And Antioxidants On A Basic Mechanism Of Beef Tenderization, Michael D. Chao

Theses and Dissertations in Animal Science

Feeding high levels of wet distillers grains plus solubles (WDGS) increases polyunsaturated fatty acid (PUFA) levels in beef. Perhaps, WDGS in feedlot diets increases PUFA concentration in the SR membrane, thereby altering membrane integrity, resulting in more rapid calcium leakage and improved tenderness. Feeding antioxidants may mitigate such effects. In the first study, effects of feeding 50 % WDGS on SR membrane composition, free calcium concentration and tenderness were studied. The SR membrane from steers fed WDGS were more tender, had higher free calcium concentration, had more PUFA, more phosphatidylcholine (PC), less phosphatidylethanolamine (PE) and less total phospholipids when compared to ...

The Influence Of The Bovine Fecal Microbiota On The Shedding Of Shiga Toxin-Producing Escherichia Coli (Stec) By Beef Cattle, Nirosh D. Aluthge 2015 University of Nebraska-Lincoln

The Influence Of The Bovine Fecal Microbiota On The Shedding Of Shiga Toxin-Producing Escherichia Coli (Stec) By Beef Cattle, Nirosh D. Aluthge

Dissertations & Theses in Food Science and Technology

During the past three decades, Shiga toxin-producing E.coli (STEC) have emerged as an important food safety concern. Although initially E. coli O157 was the main focus, recent outbreaks and resulting investigations have shown that certain non-O157 STEC are as much a threat to food safety as their O157 counterparts. To the beef industry, STEC have been of particular concern due to the frequent association of beef and beef products as vehicles of STEC infection. As a result, along with E. coli O157, six non-O157 STEC serogroups (known as the ‘big six’) are now regulated as adulterants in certain raw ...


Assessment Of Workers Exposure To Ammonia In Animal Facilities At Walter C. Todd Agricultural Research Center, Nacogdoches, Texas, Ahmad F. Nasser, Sheryll B. Jerez 2015 Stephen F Austin State University, Arthur Temple College of Forestry and Agriculture

Assessment Of Workers Exposure To Ammonia In Animal Facilities At Walter C. Todd Agricultural Research Center, Nacogdoches, Texas, Ahmad F. Nasser, Sheryll B. Jerez

Bright Ideas Conference

Poultry, swine, and equine animal facilities are all considered as Concentrated Animal Feeding Operations (CAFOs). All these CAFOs are emission sources of gases and other pollutants which have negative impacts on the environment, human health, and animal health as well. One of those gases is Ammonia (NH3), which is a colorless, highly irritating gas with a pungent, suffocating odor, and if inhaled in high concentrations, it may cause harm to the human body and the function of lungs. Personal exposure to ammonia was assessed for six workers in the three animal facilities: poultry, swine, and equine. Two workers from each ...

Relationship Between Temperament And Performance Traits In Yearling Cattle, Courtney R. Branton, C. J. Koffskey, E. O. Warden, E. G. Brown

Bright Ideas Conference

To examine relationships between exit velocity (EV, objective measure of temperament) and performance traits, calves were weighed 14 days prior to weaning, at weaning, 128 days post weaning, and at time of carcass measurements. Exit velocity obtained on day -14 and carcass ultrasound measurements (n = 6) obtained on day 208 and carcass harvest measurements (n = 12) obtained on day 349 were used to determine correlations between EV, performance and carcass measurements. Exit velocity showed a tendency to be negatively correlated (P < 0.15) with weaning weight (r = -0.40), but not correlated (P > 0.05) with average daily gain post 128 days. Exit velocity was not correlated (P > 0.05) with carcass ...

Impact Of Arbuscular Mycorrhizal Fungi On The Physiology Of Maize Genotypes Under Variable Nitrogen And Phosphorus Levels, Roberto Crespo 2015 University of Nebraska-Lincoln

Impact Of Arbuscular Mycorrhizal Fungi On The Physiology Of Maize Genotypes Under Variable Nitrogen And Phosphorus Levels, Roberto Crespo

Theses, Dissertations, and Student Research in Agronomy and Horticulture

It is important to increase our understanding of AM fungal and maize genotype interactions, the impact of N and P fertilization and water condition on the symbiosis, and on the physiology and nutritional status of maize plants. In two greenhouse experiments AM inoculated plants exhibited root colonization values around 70% which was confirmed by the presence of the AM lipid biomarker (C16:1cis11). Nitrogen fertilization increased AM root colonization, but only compared to unfertilized plants. Root colonization and biomarker concentration in root and soil were similar among inoculated maize genotypes across conventional and drought tolerant hybrids. Mycorrhizal inoculation had a ...

Producing Quality Barley For The Malting Industry, Haley H. Oser Dph

Doctoral Documents from Doctor of Plant Health Program

The University of Nebraska – Lincoln Doctor of Plant Health program requires each student to fulfill a professional internship over the last summer of the program. For my internship, I worked as a Barley Scientist Intern for MillerCoors and Golden Malting in Golden, Colorado. During this internship I gained a fundamental understanding of malting barley production with a significant emphasis on grain quality. Barley produced for malting must fulfill strict industry quality standards before it is accepted by the head maltsters. These quality standards include: a high germination rate, low moisture content, protein content within an acceptable range and the grain ...

Evaluation Of Supplemental Energy Source For Grazing Stocker Cattle, L. W. Lomas, J. K. Farney, J. L. Moyer

Kansas Agricultural Experiment Station Research Reports

Thirty-six steers grazing smooth bromegrass pastures were used to evaluate the effects of a supplemental energy source on available forage, grazing gains, subsequent finishing gains, and carcass characteristics. Supplementation treatments evaluated were: no supplement, a supplement with starch as the primary source of energy, and a supplement with fat as the primary source of energy. Supplements were formulated to provide the same quantity of protein and energy per head daily. Supplementation with the starchbased or fat-based supplement during the grazing phase resulted in higher (P < 0.05) grazing gains than feeding no supplement. Supplementation during the grazing phase had no effect (P > 0.05) on finishing gain, feed intake, and feed:gain. Steers supplemented with the ...
