Working Bodies: A Photo Essay On Tulare County Citrus Workers, Isamar Hernandez-Ramos

Agricultural Education and Communication

Many a times, when people think about their food, they think about origins. Where did it come from? Was it hygienic? Were the animals treated humanely? They seldom include the workers in their thought process, though the workers of the Ag industry provide what is arguably a vital part of the Ag industry. They do back-breaking labor in often lethal conditions for little pay (NFWM). The families of these workers often suffer economically, physically, and emotionally. In Tulare County, one of the top Agricultural counties in the country, the agricultural worker is often below the poverty line (Taylor, 2015). They …

Pink And Dude Chefs: Efficacy Of An Online Train-The-Trainer Mechanism And Student Program Outcomes, Jacqueline Chen

Master's Theses

Background: The rate of overweight and obesity among adolescents aged 12-19 years has quadrupled since 1980. Reducing obesity is a key public health priority, as obesity is associated with individual and population-level health and economic consequences. Afterschool-based obesity prevention programs that aim to develop nutrition and culinary self-efficacy have shown promise. However, the level of aptitude among program instructors is directly correlated with student success, suggesting the importance of effective train-the-trainer (TTT) mechanisms for implementing and scaling up these strategies.

Pink and Dude Chefs (PDC) is an afterschool nutrition education and culinary skills program for middle-school adolescents aged between 11-14 …

Multi-Criteria Flow-Shop Scheduling Optimization, Raviteja Arikati

Industrial and Manufacturing Engineering

A flow-shop is a type of manufacturing job shop where similar jobs follow a similar, linear sequence through the shop. Every day, flow-shops receive several different orders and it is up to the scheduler to plan the daily schedule. This schedule should be designed to prevent bottlenecks in the shop, to have on-time delivery of products, and satisfy several other requirements. Often, schedulers perform subjective scheduling and utilize simple heuristics or just intuition to schedule the jobs. With computer-based scheduling, schedulers can now create schedules and determine quantitatively what sorts of schedules work best. Currently, much of the computer-based schedules …

Influence Of Silver Nanoparticle Surface Charge On Cytotoxic Efficacy Against Cancer Cells, Elliot Christian Frey

Materials Engineering

Silver and silver-based products are known to cause cytotoxic effects to both microbes and eukaryotic cells. Because of this property, silver nanoparticles (AgNPs) are being studied for their potential in targeted tumor treatments. Previous studies with microbes suggest that AgNPs with cationic capping agents possess enhanced cytotoxicity by virtue of Coulombic attraction between the nanoparticle and the negatively-charged cell wall. Since animal cells possess similar negatively-charged plasma membranes, this research hypothesized that human cells would be more susceptible to positively-charged AgNPs than to negatively-charged AgNPs. To investigate this theory, cancerous cervical cells (HeLa) and healthy fibroblast cells (3T3) were subjected …

Characterization Of The 15-5 Stainless Steel Electric Discharge Machining Recast Layer, Julian R. Lohser, Rhys W. Gilmore

Materials Engineering

Electric discharge machining (EDM) is a non-conventional machining process that is used for tough, hard materials or materials that require no tool force. Wire EDM produces a recast layer and heat-affected zone as a result of rapid melting and quenching at the surface of the cut. A secondary machining operation has been required to remove this layer. Previous estimates of the depth of the recast layer are likely too conservative due to improvements in the technology; therefore, the goal of this study is to characterize and more accurately investigate the size of the layer. Two EDM machine parameters, voltage and …

Eighteenth Century Women And The Business Of Making Glass Music, Kate M. Hepworth

History

During the relatively short period from the mid-to-late eighteenth century when glass musical instruments were manufactured and gained popularity, several women made names for themselves in the realm of avant-garde musical performance. The lives of three female glass instrument players: Anne Ford, Marianne Davies, and Marianne Kirchgassner, show how these successful performer-entrepreneurs operated in an age of emerging feminine public identity. Their journeys reveal much about the gender dimensions of the age, the role of music in the modern era, the consumption of it, and their approach to business. The financial opportunities presented to women looking to challenge the limitations …

Inkjet Printing Of Nano-Silver Conductive Ink On Pet Substrate, Skyler Jiang

Materials Engineering

Printing of conductive ink traditionally uses copper-based ink and was used on high temperature metal substrates due to the high curing and sintering temperature of copper. In this experiment, however, Metalon JS-B25P nano-silver conductive ink was printed using an Epson Stylus C88+ inkjet printer on polyethylene terephthalate (PET) based Novele printing media made for low temperature applications. With silver’s lower sintering temperature, the nano-silver particles in this ink are desired to be able to sinter at a low enough temperature to be used on the PET substrate. The printed ink traces were cured with a temperature-controlled hotplate at 100℃, 120℃, …
