Metabolic Regulation And Cryotolerance Of In Vitro-Produced Holstein Embryos, Melissa Ann Roberts
Metabolic Regulation And Cryotolerance Of In Vitro-Produced Holstein Embryos, Melissa Ann Roberts
Master's Theses
In vitro production and transfer of embryos has become a common practice within the dairy industry to efficiently breed superior animals and meet the consumption demand of the growing population. Cyropreservation is necessary for the application of commercialized embryo transfer, however, in vitro-produced embryos show morphological and physiological defects which negatively impact their ability to withstand cryopreservation in comparison to their in vivo counterparts. These artifacts result from culture conditions that cause stress to the embryo during development, leading to an accumulation of intracellular lipids, mitochondrial dysfunction, and ultimately poor ability to withstand freezing and thawing. The objective of …
Review: Interspecies Ethics By Cynthia Willett, Thomas E. Randall
Review: Interspecies Ethics By Cynthia Willett, Thomas E. Randall
Between the Species
This paper provides a review of Cynthia Willett's book Interspecies Ethics. Willett aims to outline the beginnings of biosocial eros ethics – an ethical outline that sketches the potentiality of a cross-species cosmopolitan ideal of compassion (agape), derived through acknowledging and emphasizing the existence of spontaneous, playful interaction between social animals. Though this book is recommended for offering an innovative framework from which to explore the possibility of non-anthropocentric cross-species ethic, readers should be wary of expecting to find a fully-fledged moral program detailing how this would work.

Food science knowledge and experience obtained through education, research, and professional development are the engines for innovative solutions that have historically solved key challenges in providing food for man since ancient times, and hold the key to meeting future needs of a growing global population. The systems in place that have been used to evolve our education programs conduct research and provide continuous learning opportunities that are essential to insuring a vibrant and widely available nutritious, safe, and wholesome food supply. This article provides an overview of the topics of the hierarchy related to food science education, research, and professional …
Automated Detection Of Deep-Sea Animals, Dallas J. Hollis, Duane Edgington, Danelle Cline
Automated Detection Of Deep-Sea Animals, Dallas J. Hollis, Duane Edgington, Danelle Cline
STAR Program Research Presentations
The Monterey Bay Aquarium Research Institute routinely deploys remotely operated underwater vehicles equipped with high definition cameras for use in scientific studies. Utilizing a video collection of over 22,000 hours and the Video Annotation and Reference System, we have set out to automate the detection and classification of deep-sea animals. This paper serves to explore the pitfalls of automation and suggest possible solutions to automated detection in diverse ecosystems with varying field conditions. Detection was tested using a saliency-based neuromorphic selective attention algorithm. The animals that were not detected were then used to tune saliency parameters. Once objects are detected, …
Design Of An Aquaponics System, Jesse Birsinger
Design Of An Aquaponics System, Jesse Birsinger
BioResource and Agricultural Engineering
This Senior Project discusses the design, cost analysis, and evaluation of an aquaponics system. The system incorporates aquaculture and hydroponics to create a source of fish protein and various crops. The system was sized based off a minimum requirement of pounds of fish available per week. The system designed is capable of generating 2080 pounds of catfish, and 16,000 pounds of produce annually. The first year of operation the system will operate at a loss due to the significant cost of the components of the system, however, the project is projected to generate a minimum stream of revenue of $10,600 …
Study Of Rehydration Properties Of Powder Produced From Chelated Skim Milk, Kristina Ellice Tan
Study Of Rehydration Properties Of Powder Produced From Chelated Skim Milk, Kristina Ellice Tan
Master's Theses
Poor rehydration properties of skim milk powder (SMP) can impact processing efficiency and functionality in finished product applications. Rehydration can be split into four stages: wettability, sinkability, dispersibility, and solubility. Previous work has suggested that chelator addition during SMP manufacture leads to higher solubility compared to SMP without chelators. This study focuses on the addition of ethylene diamine tetraacetic acid (EDTA) or sodium citrate dihydrate (SCD) at concentrations of 5, 10, and 15 mM to skim milk prior to evaporating and spray drying. The objective of this investigation was to determine the effects of the chelator additions on each SMP …
Comparison Of Foaming Properties Between Chelated Reconstituted Smp And Caseinates, Boya Liu
Comparison Of Foaming Properties Between Chelated Reconstituted Smp And Caseinates, Boya Liu
Master's Theses
Caseinate powders have been well accepted because of their foaming properties. In this study, 10% solution of reconstituted skim milk powder (SMP) chelated with sodium hexametaphosphate (SHMP) and trisodium citrate (TSC) at 1 mEq, 50 mEq, and 100 mEq were prepared to conduct a comparison with sodium caseinate, potassium caseinate, and calcium caseinate solutions. Foamability, foam stability as well as the preferential locations of αs-casein, β-casein and !-casein in their foams were analyzed. It was hypothesized that the foamability, foam stability and the preferential locations of these three caseins in the milk foams are different from treatment to treatment. Milk …
Separation And Characterization Of Reconstituted Skim Milk Powder Treated With Mineral Chelators, Amy Kringle
Separation And Characterization Of Reconstituted Skim Milk Powder Treated With Mineral Chelators, Amy Kringle
Master's Theses
The proteins found in milk are largely important in the functionality of many dairy products and dairy processes. The casein micelle system in milk is a complex and highly studied system. The micelle is thought to be a sponge like structure containing four caseins, αs1, αs2, β, and κ casein, and bound together with colloidal calcium phosphate. When a chelating agent such as a citrate, phosphate, or polyphosphate are added to milk systems, the CCP is bound to the chelator and removed from the micelle. It has been shown through past research that the use of …
Short Communication: Effect Of Storage Temperature On The Solubility Of Milk Protein Concentrate 80 (Mpc80) Treated With Nacl Or Kcl, V. Sikand, P.S. Tong, J. Walker, T. Wang, L.E. Rodriguez-Saona
Short Communication: Effect Of Storage Temperature On The Solubility Of Milk Protein Concentrate 80 (Mpc80) Treated With Nacl Or Kcl, V. Sikand, P.S. Tong, J. Walker, T. Wang, L.E. Rodriguez-Saona
Dairy Science
A previous study in our laboratory showed that addition of 150 mM NaCl or KCl into diafiltration water improved the solubility of freshly made milk protein concentrate 80 (MPC80). In the present study, the objectives were (1) to evaluate the solubility of NaCl- or KCl-treated MPC80 samples kept at varying temperatures and then stored for extensive periods at room temperature (21°C ± 1°C); and (2) to determine if MPC80 samples stored at different temperatures and protein conformation can be grouped or categorized together. Freshly manufactured MPC80 samples were untreated (control), processed with NaCl, or processed with KCl. One set …

Growth Rate Of Copepods In The San Francisco Bay, Brooke Bemowski, Wim Kimmerer, Toni Ignoffo
Growth Rate Of Copepods In The San Francisco Bay, Brooke Bemowski, Wim Kimmerer, Toni Ignoffo
STAR Program Research Presentations
The San Francisco Estuary is a complex ecosystem. A key part of the foodweb are zooplankton crustaceans, specifically copepods. Many fish, especially the endangered delta smelt, rely on copepods as a food source. Measuring the growth of copepods assists in predictions if enough food is available for delta smelt. Traditionally growth rate is measured through lengthy and involved processes. The objective of this research project is to develop an imaging process to analyze biomass of copepods more efficiently. For this research, field samples of copepods were collected and grown over three days. Subsamples were taken and preserved at three predetermined …
