Homoploid Hybrid Speciation In A Rare Endemic Castilleja From Idaho (Castilleja Christii, Orobanchaceae), Danielle Leigh Clay

Boise State University Theses and Dissertations

Evidence to support the origins of a putative hybrid species with certainty must be determined using several lines of evidence: the presence of genetic additivity of parental marker alleles in a putative hybrid species, along with ecological or niche separation. Novel or transgressive morphological traits obtained through chromosomal rearrangements during hybridization may facilitate niche separation of the hybrid species from progenitor habitats. These evolutionary processes together enforce reproductive isolation and promote an independent evolutionary trajectory in hybrid species. By studying these evolutionary processes in putative hybrid species, researchers may identify hybrid species with confidence.

We employed multiple lines of evidence …

Remote Explosive Scent Tracing Rest, Gichd

Global CWD Repository

Remote Explosive Scent Tracing (REST) is essentially a survey methodology based on using dogs and rats to remotely detect landmines and explosive remnants of war (ERW). Systems similar to REST have been used in technical survey and mine clearance operations for 20 years, and have been subject to a study conducted by the Geneva International Centre for Humanitarian Demining (GICHD) since 2000.

At that time, REST was considered one of the most promising avenues for speeding up demining operations and making them more cost-efficient, very much in the spirit of the land release concept. The GICHD got involved in the …

Ferritin Diversity: Mechanistic Studies, Disease Implications, And Materials Chemistry, Robert Joseph Hilton

Theses and Dissertations

The study of ferritin includes a rich history of discoveries and scientific progress. Initially, the composition of ferritin was determined. Soon, it was shown that ferritin is a spherical, hollow protein. Eventually, over several decades of research, the structure and some function of this interesting protein was elucidated. However, the ferritin field was not completely satisfied. Today, for example, researchers are interested in refining the details of ferritin function, in discovering the role of ferritin in a variety of diseases, and in using ferritin for materials chemistry applications. The work presented in this dissertation highlights the progress that we have …

Polyanhydride Microparticles Enhance Dendritic Cell Antigen Presentation And Activation, Maria P. Torres, Jennifer H. Wilson-Welder, Senja K. Lopac, Yashdeep Phanse, Brenda Carillo-Conde, Amanda E. Ramer-Tait, Bryan H. Bellaire, Michael J. Wannemeuhler, Balaji Narasimhan

Department of Food Science and Technology: Faculty Publications

The present studies were designed to evaluate the adjuvant activity of polyanhydride microparticles prepared in the absence of additional stabilizers, excipients, or immune modulators. Microparticles composed of varying ratios of either 1,6-bis(p-carboxyphenoxy)hexane (CPH) and sebacic acid (SA) or 1,8-bis(p-carboxyphenoxy)-3,6-dioxaoctane (CPTEG) and CPH were added to in vitro cultures of bone marrow-derived dendritic cells (DCs). Microparticles were efficiently and rapidly phagocytosed by DCs in the absence of opsonization and without centrifugation or agitation. Within 2 h, internalized particles were rapidly localized to an acidic, phagolysosomal compartment. By 48 h, only a minor reduction in microparticle size was …

The Effectiveness Of Process Oriented Guided Inquiry Learning To Reduce Alternate Conceptions In Secondary Chemistry, Michelle Jones Barthlow

Doctoral Dissertations and Projects

A nonequivalent, control group, pretest-posttest design was used to investigate student achievement in secondary chemistry. This study investigated the effect of process oriented guided inquiry learning (POGIL) in high school chemistry to reduce alternate conceptions related to the particulate nature of matter versus traditional lecture pedagogy. Data were collected from chemistry students in four large high schools and analyzed using ANCOVA. The results show that POGIL pedagogy, as opposed to traditional lecture pedagogy, resulted in fewer alternate conceptions related to the particulate nature of matter. Male and female students in the POGIL group posted better posttest scores than their traditional …

Effect Of Freshman Chemistry On Student Performance In Sophomore Engineering Courses, Michael A. Collura, Shannon Ciston, Nancy Ortins Savage

Chemistry and Chemical Engineering Faculty Publications

The role of first year chemistry courses in engineering programs varies somewhat across programs and disciplines. Clearly most engineering majors will encounter chemistry topics of a general nature in some of their upper-level course work. The purpose of requiring chemistry in the first year, however, goes well beyond learning chemical concepts. As a quantitative science, chemistry requires the use of math, principally algebra, on a regular basis in solving various problems. Students should gain an appreciation of the importance of units in solving problems should come to understand the difference between implicit and explicit properties and should develop other quantitative …

The Hemocompatibility Of A Nitric Oxide Generating Polymer That Catalyzes S-Nitrosothiol Decomposition In An Extracorporeal Circulation Model, Terry C. Major, David O. Brant, Charles P. Burney, Kagya Amoako, Gail M. Annich, Mark E. Meyerhoff, Hitesh Handa, Robert E. Bartlett

Mechanical and Industrial Engineering Faculty Publications

Nitric oxide (NO) generating (NOGen) materials have been shown previously to create localized increases in NO concentration by the catalytic decomposition of blood S-nitrosothiols (RSNO) via copper (Cu)-containing polymer coatings and may improve extracorporeal circulation (ECC) hemocompatibility. In this work, a NOGen polymeric coating composed of a Cuo-nanoparticle (80 nm)-containing hydrophilic polyurethane (SP-60D-60) combined with the intravenous infusion of an RSNO, S- nitroso-N-acetylpenicillamine (SNAP), is evaluated in a 4 h rabbit thrombogenicity model and the anti-thrombotic mechanism is investigated. Polymer films containing 10 wt.% Cuo-nanoparticles coated on the inner walls of ECC circuits are employed concomitantly with systemic SNAP administration …

A Topological Approach To Molecular Chirality, Erica Flapan

Pomona Faculty Publications and Research

Topology is the study of deformations of geometric figures. Chemistry is the study of molecular structures. At first glance these fields seem to have nothing in common. But let’s take a closer look to see how these fields come together in the study of molecular symmetries.

Multiple Benzene-Formation Paths In A Fuel-Rich Cyclohexane Flame, Wenjun Li, Matthew Law, Phillip Westmoreland, Tina Kasper, Nils Hansen, Katharina Kohse-Höinghaus

United States Department of Energy: Publications

Detailed data and modeling of cyclohexane flames establish that a mixture of pathways contributes to benzene formation and that this mixture changes with stoichiometry. Mole-fraction profiles are mapped for more than 40 species in a fuel-rich, premixed flat flame (Φ = 2.0, cyclohexane/O₂/30% Ar, 30 Torr, 50.0 cm/s) using molecular-beam mass spectrometry with VUV-photoionization at the Advanced Light Source of the Lawrence Berkeley National Laboratory. The use of a newly constructed set of reactions leads to an excellent simulation of this flame and an earlier stoichiometric flame (M.E. Law et al., Proc. Combust. Inst. 31 (2007) 565–573), …

Prehistoric Plant Procurement, Food Production, And Land Use In Southwestern Tamaulipas, Mexico, John Hanselka

All Theses and Dissertations (ETDs)

In this dissertation, I examine plant use, food production, and land use in the Ocampo region of southwestern Tamaulipas, northeastern Mexico. In the early 1950s Richard S. MacNeish excavated in a series of dry cave sites within the study area and discovered evidence for the local adoption of domesticated plants and the subsequent development of a mixed foraging-farming economy that persisted for millennia, before culminating in the establishment of settled farming villages. This research remains central to discussions of early Mesoamerican agriculture. However, the spectrum of land use and wild plant utilization over the prehistoric sequence remains poorly understood, as …

New Synthetic Methodologies For The Construction And Optimization Of Natural Products, Amir E. Wahba

Electronic Theses and Dissertations

Toxicity associated with bioactive natural products is considered as a major obstacle in the process of drug discovery. Manzamine A (MA) is one such candidate that requires optimization to overcome the toxicity problem. The manzamine alkaloids represents a unique class of natural products that have shown a diverse range of bioactivities including antimicrobial, antiparasitic, cytotoxicity, anti-inflammatory, pesticidial, and was shown to possess activity against HIV-1 and AIDS opportunistic infections. The greatest potential for the manzamine alkaloids appears to be against malaria and neuroinflammation. Experimental and modeling studies suggested that the planer ?-carboline moiety can act as DNA intercalator and hence …

Synthesis Of Molecular Containers Based On Modifications Of Resorcin(4)Arene And Calix(4)Arene, Anupama Makineni

Masters Theses

This research work was mainly focused on the synthesis of molecular containers based on modifications ofresorcin[4]arene and calix[4]arene.

The modifications of resorcin[ 4 ]arene include the attempts to attach a phthalimide featured linker onto the phenol hydroxyl groups of resorcin[4]arene. A few halogen leaving groups were used, including fluorine, chlorine, and bromine. The substitution with tetraflorophthalimide resulted in a mixture of regio-isomeric products, whereas for 4,5-dichloro- and 4,5-dibromophthalimides, no desired substitution product was formed. It was, however, discovered that both 4,5-dichloro- and 4,5-dibromophthalimides forms monoclinic crystals. The second modification of resorcin[4]arene focused on functionalizations of both upper and lower rims …

Evaluating Methods For Optimizing Classification Success From Otolith Tracers For Spotted Seatrout (Cynoscion Nebulosus) In The Chesapeake Bay, Stacy Kavita Beharry

OES Theses and Dissertations

Identifying the natal sources of fish is an important step in understanding its population dynamics. Adult recruits are often sourced from multiple nursery areas, with good quality locations contributing disproportionately more fish to the adult stock. Because population persistence is strongly influenced by nursery habitat, methods that correctly identify the source of recruits are necessary for effective management. Within the last decade, otolith chemistry signatures have been increasingly used as a natural marker to delineate fish from a mixture of nursery sources. Despite the widespread use of otolith trace element and stable isotope ratios as habitat markers, the statistical approaches …
