Nutrition And Health Status Of Hemodialysis Patients In Dhaka, Bangladesh, Tanjina Rahman

Wayne State University Dissertations

Methods to identify patients at risk for End stage renal disease (ESRD) are a high priority in Bangladesh, where kidney transplants/dialysis options are limited and costly. Every year, 35,000 to 40,000 people reach ESRD in Bangladesh, but currently available facilities can hardly accommodate only 9000 to 10,000 new patients with twice weekly dialysis and the remaining 66% have no access to any kind of renal replacement therapy (RRT) in the form of dialysis or transplantation. Nutrition is an important factor in maintaining good health of hemodialysis patients. However, data on nutritional status of Bangladeshi dialysis patients is limited and is …

Managing Forest Disturbances: Effects On Mule Deer And Plant Communities In Montana's Northern Forests, Teagan Ann Hayes

Graduate Student Theses, Dissertations, & Professional Papers

Mule deer (Odocoileus hemionus) are frequently the focus of population and habitat management in the western United States. Land and wildlife managers use disturbance to reset forests to earlier successional stages and improve the quality and quantity of forage available to mule deer. However, the effects of management practices on nutrition and selection vary widely, so the implementation of management practices raises ecological as well as management-related concerns. This work investigated how disturbance from wildfire, prescribed fire, and timber harvest influences the spatial and temporal distribution of nutritional resources in mule deer summer range, and therefore, how the …

Home Is Where The Food Is: Causes And Consequences Of Partial Migration In Elk, Kristin Jennifer Barker

Graduate Student Theses, Dissertations, & Professional Papers

Migratory and non-migratory ungulates often coexist in partially migratory populations, but the mechanisms that drive and maintain different migratory behaviors within the same herd are poorly understood. In western North America, increasing numbers of elk (Cervus canadensis) reside on low-elevation winter range year-round. These residents can cause issues associated with crop damage, potential for disease transmission to livestock, and reduced effectiveness of harvest management strategies. Because migrants transfer nutrients, alter carnivore distributions, and structure vegetative communities across seasonal ranges, reductions in migratory behavior raise ecological as well as management-related concerns. This work investigated the factors affecting migratory behavior …

Water Management Efficiency In The Food And Beverage Industry, Maria Del C Reyes Torres

Walden Dissertations and Doctoral Studies

Water is critical for food production, food security, and health. Water quality management influences freshwater sustainability, land, and energy administration. Global agriculture accounts for more than 70% of all water consumption; the fertilizer, manure, and pesticide overspills are chief sources of water pollution worldwide. On a global scale, food-related waste directly impacts local food production and water resource management. The purpose of this multiple-case study on the food and beverage (FB) industry in the State of Georgia was to identify successful strategies for improving water management efficiency. The concepts of systems thinking, adaptive resource management, and integrated water resource management …

Feasibility Of Using Biofuel By-Products As A Sustainable Nutritional Resource For Aquaculture Production Of Litopenaeus Vannamei, Erik David Demicco

HCNSO Student Theses and Dissertations

Many different algal species can provide an acceptable protein ingredient, with good digestibility, for shrimp feeds. Compared to fish meal, similar protein, carbohydrate, and lipid levels can be found in select algal species. Traditional shrimp diets in aquaculture rely on fish meal and fish oil from pelagic fish fisheries. A reduction or elimination of these ingredients would reduce the dependency of shrimp aquaculture on offshore fisheries and increase economic competiveness. Biofuel production produces algal by-products of potential use to aquaculturists that might reduce or eliminate the need for fisheries products in shrimp feed. Established uses for by-products from biofuel production …

Growing Roots: Gardening As A Means To Mitigate Urban Poverty And Its Symptoms, Maeve Bassett

2014 Student Theses

Urban gardening has become a very popular trend in the last few years in both affluent neighborhoods as a form of relaxation and in impoverished areas as a form of hunger relief. In impoverished areas, urban gardens are usually exclusively advertised as a solution to limited food access; however, there is a naïve belief that these gardens are effective forms of mass food production. Presently, these gardens are not productive enough to globally effect food production and the environment. However, to the communities surrounding the gardens, the effects are immense. Urban gardens are cheap and effective solutions for many of …

"Planting Wholesome Seeds": Organic Farming And Community Supported Agriculture At Sweetwater Organic Community Farm, Philip R. Mcnab

USF Tampa Graduate Theses and Dissertations

Sweetwater Organic Community Farm is an organic farm and environmental education center located in Tampa, Florida. The farm employs the community supported agriculture (CSA) model, in which members pay a single fee before the growing season begins and receive a weekly or biweekly share of the ongoing harvest in return. Using multiple ethnographic methods, this research aimed to understand the daily operations at Sweetwater as well as the perceptions of staff and CSA members. Findings indicated that there were myriad perceived advantages of organic agriculture but also imposing challenges that needed to be overcome. Moreover, staff members acknowledged the challenges …

The Homestead: Revisited, Christopher William Kramer

Masters Theses, 2010-2019

This paper discusses ideas for harmony on 100 acres in mid-eastern New York. Problems leading to this research include the depletion of resources from irresponsible energy use and profit-driven industrial agriculture; dependency on fossil fuels and centralized energy; and lack of connection between people within communities, with their environment, and with sources of food and water. It is feared that sustainable, resilience building practices that nourished generations throughout history are being neglected. This specific application provides depth and concreteness to the discussion and planning process. Resources including books, maps, reports, and periodicals were integrated to select the site and plan …

Measurement Of Nutrient Availability In Feedstuffs For Florida Pompano And Development Of Formulated Diets For Pompano Aquaculture, Craig Gothreaux

LSU Master's Theses

Consistently high market demand combined with low commercial catches have made Florida pompano, Trachinotus carolinus, one of the highest valued finfish from the Gulf of Mexico. Economic incentive has spurred interest in pompano culture since the 1950s, yet the body of nutritional research on pompano is still sparse. This study was conducted to measure the apparent digestibility of nutrients among a selection of common feed ingredients, and determine the optimum dietary protein level for juvenile Florida pompano at a fixed protein-to-energy ratio, in order to formulate nutritionally complete, cost-effective diets. The four ingredients tested in the digestibility trial were soybean …

Humic And Fulvic Acids: Effects On Plant Nutrition And Growth, Jason Tew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humic substances are reported to improve plant growth and nutrient uptake, with iron the most studied nutrient. The most common forms of iron in soils are iron oxides, which are stable under aerobic conditions and unavailable for plant uptake. Iron deficient plants become chlorotic, which reduces growth and yield. To determine if humic substances can reduce iron chlorosis, five commercially available organic acids were tested on maize grown in sand columns at high pH. The dry granular humic acid from Aldrich Chemical Company applied at 84.4 g/liter of sand by volume (5% by mass) and 1 g/liter added with irrigation …

Planning For Basic Needs In India: A Supplement., Monoj Kumar Panda Dr.

Doctoral Theses

Problems of economic development have received a great deal of attention in the last four decades. This has led to the evolution of several development goals like growth, redistribution, poverty alleviation and basic needs satiafac- tion. Initially, development atrategies e eared to were achieve maximum feasible growth rates. It was generally felt that the benefits of growth would spread widely to different sections of the population and in particular would percolate to the lower income groups. Judged by growth in national income, the development efforts have been successful, though to varying ext ent in different countries. But the percola- tion …

Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

Nutrition Of Sheep Grazing Foothill Big Game Range In Spring, Kurt J. Kotter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sheep with esophageal fistulas were used to determine the daily intake, nutritive content and digestibility of forage at three periods and two stocking intensities during the spring of 1972 on a typical foothill range in northern Utah.

Heavy grazing under a season-long regime did not influence the concentrations of dietary chemical components when compared to moderate grazing; however, it did depress the digestibility of cellulose and organic matter. There was a significant decline in the dietary chemical components due to forage maturation. Digestibility of organic matter and cellulose were significantly higher in the early spring as compared to late spring. …

Such tongue pigmentation does not seem to have been reported for any population, human or otherwise.Tongue pigmentation be usually found on the upper surface or borders …

Growth And Nutrition Of Plants As Affected By Different Osmotic Concentrations Of Calcium Chloride And Sodium Chloride In The Substrate, Mumtaz Ali Khan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Considerable experimental evidence supports the concept that the growth of plants generally decreases progressively as the salt concentration of the substrate increases, but certain relationships between plant and substrate are still not fully understood. The chemistry of salt toxicity to plants involves many interactions both as to the quantity and kind of ions presented to the roots and those accumulated in the plants. Many plant species have shown sensitivity to excess accumulation of specific salts frequently encountered in saline soils. Thus Eaton (1942), Wadleigh, Hayward, and Ayers (1951) have shown most of the fruit trees to be susceptible to injury …
