Furniture Design And Product Development Principles Considering End-Of-Life Options And Design For Environment Strategies, Mesut Uysal

Open Access Theses

During last decades, environmental issues come into prominence and some governmental or organizational regulations are legislated to reduce environmental impacts of products within their life cycle. At the same time, costumers consider not only price, quality, branding, uniqueness, availability but also environmental impact, safety, and overall sustainability of products they select. Therefore, producers are addressing environmental impact of products they are producing and also making changes to their production process. This project is addressing End-of-Life (EoL) Options of wooden furniture. ^ Although wood is eco-friendly and natural material, its technological process, use and disposal might have ecological problem and challenge. …

Field To Flight: A Techno-Economic Analysis Of Stover To Aviation Biofuels Supply Chain, Amanda C. Bittner

Open Access Theses

Greenhouse gas emissions have been a growing concern. The transportation sector contributes to one-third of GHG emissions in the United States from fossil fuel burning. The Renewable Fuel Standard set a requirement for 16 billion gallons (ethanol equivalent) of cellulosic biofuels to be used in the market. Aviation biofuels can help to meet both of these problems as well as improve U.S. energy security.

Investment in the biofuel industry carries a lot of risk. The biofuel industry is run by the private sector, but can be incentivized by government. Cellulosic biofuels carry even more risk than first generation biofuels, because …

Price Impacts Of Increased Peruvian Table Grape Supply, Jacob W. Iest

Open Access Theses

In the last decade, Peru has begun to structure its economy and complete infrastructure projects to promote agricultural export growth. Bolstered by the signing of the Peru Trade Promotion Agreement (PTPA) with the U.S., table grape production has increased significantly since 2006. Peru has a climatic advantage for a quality harvest from November to March, which overlaps the end of the U.S. growing season. With this supply increase expected to continue, U.S. producers and marketers question the effect Peru will have on "late-season" table grape prices in North America.

This thesis is a study of the effects of an increase …

Essays On Productivity Growth In Agriculture, Uris Lantz Caldo Baldos

Open Access Dissertations

This dissertation aims to explore the current trends in agricultural productivity and analyse its impact on the global farm and food system. Chapter 2 in this dissertation looks at the current trends in agricultural productivity in India—one most of the populous country in the world. In this chapter, productivity trends in Indian agriculture are examined by looking at changes in Total Factor Productivity—a measure which takes into account all farm outputs and inputs. Estimates in this chapter suggest that TFP growth for the 10-year period—between 1999-2000 and 2009-2010—steadily grew at the national level. Looking at the 5-year estimates, TFP growth …

Functional Genomics Of Maize Endosperm Maturation And Protein Quality, Lingling Yuan

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Maize is one of the most important cereal crops and widely cultivated throughout the world. The study on maize kernel development including protein quality improvement is essential for removing dietary protein deficiency because of the lack of essential amino acids, especially lysine and tryptophan, in maize kernel. Quality Protein Maize (QPM) is a hard kernel variant of the high-lysine mutant, opaque-2. We created opaque QPM variants to identify opaque-2 modifier genes and to investigate deletion mutagenesis combined with Illumina sequencing as a maize functional genomics tool. A K0326Y-QPM deletion mutant, line 107, was null for the 27- and 50-kD …

The Ecological Impact Of Casitas On Caribbean Spiny Lobster (Panulirus Argus) Populations In The Florida Keys, Fl, (Usa), Benjamin C. Gutzler

Biological Sciences Theses & Dissertations

Casitas are artificial structures placed on the seabed by fishermen to aggregate Caribbean spiny lobsters (Panulirus argus) for ease of capture. Some researchers suggest that they may also enhance lobster populations in shelter-limited environments. Conversely, aggregation of lobsters within casitas may be detrimental to the population if the nutritional condition or mortality of lobsters is poorer in casitas than in natural shelters. Small juvenile lobsters may be at particular risk because their foraging range is smaller and they are more readily preyed upon than larger lobsters. If so, then casitas placed in lobster nurseries may function as "ecological traps"; wherein …

Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores

Honors College Theses

The human has caused a far greater impact on the planet's biodiversity than any other species in existence, due to the impact of population, afflluence, and technology. This thesis will argue the importance of biological diversity and how affluent populations are reducing biodiversity through the consumption of meat, electronics, and motor vehicles. Aldo Leopold's "The Land Ethic" and Herman Daly's "The Impossibility Theorem", among others, create a rubric evaluating human activities and provide alternative views on economic impossibilities. Consumption is reviewed from an ecocentric perspective, a holistic outlook placing emphasis on the ecosystem. The reader will become cognizant of their …

Characterization Of Water-Solid Interactions In Crystalline Ingredients And Development Of Deliquescence Measurement Recommendations, Matthew C. Allan

Open Access Theses

There are five major mechanisms of water-solid interactions. The primary focus of this thesis was on two of these: deliquescence and hydrate formation. Many crystalline food ingredients are deliquescent compounds (e.g., NaCl, sucrose, and ascorbic acid) and some are both deliquescent and hydrate formers (e.g., glucose, thiamine HCl, citric acid). Deliquescence is the first order phase transformation of a crystalline solid to a solution above a critical relative humidity (RH) known as the deliquescence point (RH0). A crystalline hydrate is a pseudo-polymorph in which water is incorporated into the crystal structure, altering the molecular formula and the physical properties.^ To …

An Overview Of The Gene Regulatory Network Controlling Trichome Development In The Model Plant, Arabidopsis, Sitakanta Pattanaik, Barunava Patra, Sanjay Kumar Singh, Ling Yuan

Kentucky Tobacco Research and Development Center Faculty Publications

Trichomes are specialized epidermal cells located on aerial parts of plants and are associated with a wide array of biological processes. Trichomes protect plants from adverse conditions including UV light and herbivore attack and are also an important source of a number of phytochemicals. The simple unicellular trichomes of Arabidopsis serve as an excellent model to study molecular mechanism of cell differentiation and pattern formation in plants. The emerging picture suggests that the developmental process is controlled by a transcriptional network involving three major groups of transcription factors (TFs): the R2R3 MYB, basic helix-loop-helix (bHLH), and WD40 repeat (WDR) protein. …

Development Of Genetic Ssr Markers In Blumeria Graminis F. Sp. Hordei And Application To Isolates From Australia, Madeline Tucker, C S. Moffat, Simon R. Ellwood, K C. Tan, Kithsiri Jayasena, Richard P. Oliver

Biosecurity Research Articles

The barley powdery mildew pathogen, Blumeria graminis f. sp. hordei (Bgh), exists in numerous haplotypes and displays significant differences in fungicide sensitivity. It causes considerable yield losses throughout the world. Microsatellite SSRs are useful tools to study the population level and biogeographic aspects of intraspecific diversity, but so far none have been defined for Bgh. Here, eight polymorphic microsatellite loci were identified and characterized. Primer pairs amplifying the loci were then applied to 111 isolates of Bgh from Australia. The number of alleles per locus ranged from 4 to 13, and Nei's genetic diversity ranged from 0·25 to 0·76. The …

A Systematic Revision Of North American Tolypella A. Braun (Charophyceae, Charophyta), William Perez

Dissertations, Theses, and Capstone Projects

Charophyta comprises the algal classes Mesostigmatophyceae, Chlorokybophyceae, Klebsormidiophyceae, Coleochaetophyceae and Zygnematophyceae and the land plants. However, the precise phylogenetic position of these algal classes with respect to land plants is unresolved as are the phylogenetic relationships among genera in Charophyceae (Characeae). Characeae contains two tribes with six genera: tribe Chareae (Chara, Lamprothamnium, Lychnothamnus and Nitellopsis) and tribe Nitelleae (Nitella and Tolypella). Tolypella was considered the third most species-rich genus but, in the most comprehensive taxonomic treatment of Characeae, 16 Tolypella species were consolidated into two species, T. nidifica and T. intricata in sections Rothia …
