Biodegradable Cellulose Films As Alternatives To Plastics, Cecilia Wambui Wanjuu
Biodegradable Cellulose Films As Alternatives To Plastics, Cecilia Wambui Wanjuu
Electronic Theses and Dissertations
Plastics are versatile and have desirable packaging characteristics such as flexibility, durability, and affordability. The production of plastics has increased over the years resulting in concerns about their single-usage and disposal. Since plastics are nonbiodegradable, they have been associated with detrimental health impacts due to the leaching chemicals from the landfills and their accumulation in the natural and marine environment. Cellulose obtained from agricultural residues is a viable substitute because of its low density, biocompatibility, biodegradability, low toxicity, and a strong and stiff structure. However, the extraction of cellulose has been less exploited because of its insolubility in water and …

Biodegradable Biomaterials As Suitable Alternatives To Water Treatment Technologies, Most Farzana Yesmin
Electronic Theses and Dissertations
Nitrates and phosphates are essential nutrients for plants growth. Their excess presence in water, however, could cause eutrophication affecting the water quality and altering the aquatic ecosystem. Algal blooms and the presence of toxins such as microcystin in freshwater bodies are hazardous to humans, animals, and wildlife. Conventional technologies such as ion exchange, distillation, reverse osmosis, and bioreactors aid immensely to remove nutrients; however, they are expensive. Furthermore, building new nitrate and phosphate treatment units, maintenance and post-disposal are costly too. In this regard, there exists an unmet need for alternative processes that are renewable and cost-effective to treat contaminated …

Functional Analysis Of Squamosa-Promoter Binding Protein Like 13 In Controlling Flowering Time, Plant Architecture, Grain Size, And Grain Number In Wheat, Ajay Gupta
Electronic Theses and Dissertations
Higher and stable yield is always a major objective of wheat genetic improvement programs. The SQUAMOSA-promoter binding protein-like (SPL) genes constitute a small family of plant-specific transcription factors with diverse functions in plant development and growth and have great potential in improving yield and other major agronomic traits. However, the functional characterization of the SPL gene family in wheat is far behind other cereal crops such as rice. Using phylogenetic analysis, we identified 56 wheat orthologues of rice SPL genes belonging to 19 homoeologous groups. Among these 19 orthologous TaSPL genes, nine harbor the micro RNA 156 recognition element (MRE) …

Profiling Transcription And Retrotransposition Of Mouse L1 Subfamilies, Lingqi Kong
Electronic Theses and Dissertations
Transposable elements, also called jumping genes, comprise almost 45% of the human genome. In contrast, only 1% of the human genome is protein-coding sequences. The function and advantages of maintaining such massive copies of transposable elements in the human genome are still unclear. Long interspersed element 1 (L1), the most substantial group and the only active autonomous transposable element in the human genome, has revealed its unique roles in many diseases. The insertional mutagenesis induced by L1 retrotransposition events could threaten human genomic stability and generate unexpected mutations. L1 overexpression has been documented in both somatic and germline cells and, …

Evaluation Of Processing Variables To Increase The Solids Of Milk Protein Concentrates Prior To Drying, Achyut Mishra
Evaluation Of Processing Variables To Increase The Solids Of Milk Protein Concentrates Prior To Drying, Achyut Mishra
Electronic Theses and Dissertations
It is a common practice in dairy industries to nanofilter milk protein concentrate (MPC) to increase the solids and further drying efficiency. Increasing protein and solids in MPC increases viscosity and resist feed-flow in membrane filtration. Previous research proved that increased temperature and hydrodynamic cavitation (HC) have significantly reduced the viscosity of MPC which can potentially increase the level of solids by reducing concentration polarization during nanofiltration (NF). We utilized plate and frame filtration (PF) as an alternate method to reduce the viscosity of MPC. In first objective, we studied the application of HC or elevated temperature (50˚C) or both …
