Development Of A Novel Vertebrate Pesticide For The Invasive Small Indian Mongoose, Carmen Antaky, Steven C. Hess, Israel Leinbach, Robert T. T. Sugihara, Emily W. Ruell, Shane Siers

United States Department of Agriculture Wildlife Services: Staff Publications

Small Indian mongooses are detrimental introduced predators in the United States, where they depredate native species, serve as vector of disease, and threaten public safety. Due to the risk of accidental introduction to mongoose-free islands, high cost and limitations to trapping, and no national (Section 3) Environmental Protection Agency (EPA)-registered toxicants for mongoose control, there is a need for an efficacious toxic bait for mongooses for use in conservation areas and at points of entry in the United States. Over the last five years, the National Wildlife Research Center (NWRC) worked to develop a toxic bait for mongooses for registration …


The Chemistry Laboratory Experience Of El Camino Students While In Emergency Remote Teaching Due To The Covid-19 Pandemic, Shaun A. Cook Jan 2022

The Chemistry Laboratory Experience Of El Camino Students While In Emergency Remote Teaching Due To The Covid-19 Pandemic, Shaun A. Cook

Theses and Dissertations

Future college environments, including those in chemistry, will entail flexible formats. The pandemic spurred appreciation of the need, and though it has largely passed, adaptability to multiple formats in the future has been a critical part of planning for a rapidly changing future. Experiences during the pandemic will guide pedagogical changes and practices in the future. At El Camino College in Southern California, the chemistry department provided varied laboratory instruction to students during Emergency Remote Teaching. Understanding the experience students had during this extraordinary time is essential. Students who took courses that had an online laboratory course completed a mixed-methods …


Heterogeneous Oxidation Of Multi-Component Aqueous Organic Aerosols: The Effect Of Transport Phenomena And Reaction Compartment On Reaction Kinetics., Tadini Wenyika Masaya Jan 2022

Heterogeneous Oxidation Of Multi-Component Aqueous Organic Aerosols: The Effect Of Transport Phenomena And Reaction Compartment On Reaction Kinetics., Tadini Wenyika Masaya

Graduate Theses, Dissertations, and Problem Reports (ETD)

The surface-bulk partitioning of small organic molecules in aqueous droplets was investigated using molecular dynamics. The air-particle interface was modeled using a 80-Å cubic water box containing series of organic molecules and surrounded by gaseous OH radicals. The properties of the organic solutes within the interface and the water-bulk were examined at a molecular-level using density profiles and radial pair distribution functions. Molecules containing only polar functional groups such as urea and glucose are found predominantly in the water bulk, forming an exclusion layer near the water surface. Substitution of a single polar group by an alkyl group in sugars …
