Stereospecific Cross-Coupling Reactions Of Enantioenriched Secondary Alkyltricyclohexyltin Nucleophiles, Meruyert Binayeva

Dissertations, Theses, and Capstone Projects

Transition metal-catalyzed cross-coupling reactions have evolved into a remarkable instrument for the formation of new bonds, and have significantly impacted how we approach to access complex organic molecules. Palladium is currently one of the most popular elements for catalytic applications due to its ability to facilitate powerful carbon-carbon and carbon-heteroatom couplings. Traditional Pd-catalyzed cross-coupling reactions have primarily concentrated on C(sp2)-C(sp2) cross-couplings, yielding planar products. Considering the use of C(sp3) nucleophiles would offer a viable control of the three dimensional arrangement in molecules. Herein, the first chapter details the history and development of Pd-catalyzed Stille cross-coupling reactions. The use of configurationally …

The Microscopical Evidence Traces Analysis Of Household Dust And Its Statistical Significance As A Definitive Identification Technique, Stephanie Polifroni

Dissertations, Theses, and Capstone Projects

Evidence found at crime scenes is used to assist in creating a link the suspect, the victim, and the scene. As stated by the Locard’s Principle, every contact leaves a trace, that evidence can be used to link together an investigation. Traces are collected in hopes that they can be identified and associated to an individual or individuals to help solve that particular crime. However, the strongest conclusion for evidence traces is an association to a source, and unless a physical match of some kind is found, an individualization cannot be established even when known sample is available. However, having …

Approach To Dual Base And Sugar Modification Of Adenosine, Cross-Dehydrogenative Coupling Reactions Of Quinazolinones, And A Novel Entry To Carbazolones And Indolones, Dellamol Sebastian

Dissertations, Theses, and Capstone Projects

Analogues of purine nucleosides are of interest due to their antiviral, antibacterial, and anticancer properties. Although there are large number of reports on C6-modification of 6-chloropurine nucleosides with alkyl amines via the S_NAr reaction pathway, there are fewer reports on comparable reactions with aryl amines. Notably, S_NAr reactions of 6-chloropurine nucleosides with electron-deficient aryl amines is a relatively understudied area. A simple method has been developed for the S_NAr reactions of 6-chloropurine ribonucleosides with electron-deficient-, electron-rich-, and electronically neutral aryl amines. Under the developed conditions, S_NAr reactions of 2’,3’,5’-O-(tert …

Anatomy And Physiology Preparatory Course Textbook (2nd Edition), Carlos Liachovitzky

Open Educational Resources

The goal of this preparatory textbook is to give students a chance to become familiar with some terms and some basic concepts they will find later on in the Anatomy and Physiology course, especially during the first few weeks of the course.

Organization and functioning of the human organism are generally presented starting from the simplest building blocks, and then moving into levels of increasing complexity. This textbook follows the same presentation. It begins introducing the concept of homeostasis, then covers the chemical level, and later on a basic introduction to cellular level, organ level, and organ system level. This …

Water-Responsive, Peptide-Based Crystals, Roxana Piotrowska

Dissertations, Theses, and Capstone Projects

Water-responsive (WR) materials  that exert significant forces in response to changing hydration levels are receiving growing interest due to their potential applications, including use as actuators for energy harvesting devices, artificial muscles, and soft robotics. Reported examples include biological and synthetic materials with abilities to efficiently convert the chemical potential of water into mechanical actuations. However, these systems are typically complex, and consequently, their WR mechanisms are not well-understood thus preventing rational design and optimization. This thesis demonstrates the design and development of WR peptide crystals that mimic and enhance understanding of natural WR systems. The peptide crystals, with intrinsic …

Cultural Competence: Issues And Benefits In Healthcare Delivery, Tetiana Soloviova, Amina Shahbaz, Fahaneda Hassan, Zoya Vinokur

Publications and Research

The extreme growth of New York State population causes to bring more challenges and opportunities for healthcare organization to provide culturally competent service to meet the need of diverse population. According to data from the US Census Bureau, minority groups are projected to make up nearly 50% of the population by the year 2050 compared with 30% in 2000. Outside of ethnicity, there are also many cultural and social groups with which people identify that may affect how they view or receive healthcare. It is very difficult to provide quality service for a diverse population due to language barriers, health …

Evaluation Of A Direct Pcr Method And The Qiagen Investigator 24plex Go! Kit For Typing Blood, Saliva And Touch Dna On Multiple Substrates, Angelita Pierre-Noel

Student Theses

In forensic DNA typing, omitting the DNA extraction procedure and adding the sample directly to the polymerase chain reaction (direct PCR) mixture has several advantages. Without extraction and purification, there is less of a risk of sample loss, sample mix up, or contamination. This study tested the feasibility of direct PCR using the Qiagen® Investigator® 24plex GO! Kit, a megaplex kit that amplifies 22 polymorphic STR markers and the Amelogenin sex determination alleles. Test samples included blood, saliva and skin cells on porous substrates, specifically denim, white cotton, polyester fabric, and paper tissue. Glass slides were used to represent non-porous …

Gosnell Studies And Communicates Ecological Concerns, Aldemaro Romero Jr.

Publications and Research

Scientists who study environmental problems know that the more you work in the field, the more insight you gain into how to solve problems. In other words, the more field experience you have, the deeper your understanding of nature.

One scientist who has had a lot of field experience is Dr. Stephen Gosnell, and his interest in the environment began when he was still a child. “I had interest really early. I grew up in rural South Carolina in a very small town called Landrum. I was outside on a regular basis, playing in the streams and creeks around me,” …

Beyond The Obvious: Emerging Contaminants And Biogeochemistry As A Cause And Solution For Nitrogen Pollution, Stephanie L. Devries

Dissertations, Theses, and Capstone Projects

Following a comprehensive review of the occurrence and impacts of antibiotics and related pharmaceutical compounds on the terrestrial N-cycle, three experiments were performed to explore the topic of biogeochemistry as a source or a sink for N-pollution. The first of these experiments addresses the question of whether environmentally relevant concentrations of antibiotics (µg·kg^-1) have a significant effect on denitrification or N₂O production, a question that has not been well addressed in previous studies. Having determined that there is a significant shift, the second study aims to comprehensively follow changes to soil N pools and N_{2 …}

Comparative Phylogeography In The Atlantic Forest And Brazilian Savannas: Pleistocene Fluctuations And Dispersal Shape Spatial Patterns In Two Bumblebees, Elaine Françoso, Alexander Rizzo Zuntini, Ana Carolina Carnaval, Maria Cristina Arias

Publications and Research

Background: Bombus morio and B. pauloensis are sympatric widespread bumblebee species that occupy two major Brazilian biomes, the Atlantic forest and the savannas of the Cerrado. Differences in dispersion capacity, which is greater in B. morio, likely influence their phylogeographic patterns. This study asks which processes best explain the patterns of genetic variation observed in B. morio and B. pauloensis, shedding light on the phenomena that shaped the range of local populations and the spatial distribution of intra-specific lineages.

Results: Results suggest that Pleistocene climatic oscillations directly influenced the population structure of both species. Correlative species distribution models predict that …

Botanical Therapeutics In The Modern World, Vyacheslav Dushenkov, Brittany L. Graf, Mary Ann Lila

Publications and Research

Plants are the source of a broad spectrum of biologically active phytochemicals. For effective defense against pathogens and abiotic stress, plants have developed complicated chemical strategies with different mechanisms of action. By harnessing these phytochemicals, humans have used plants for medicinal purposes for over 30,000 years, and they remain a valuable source for the development of modern therapeutics. Plant-derived materials are utilized as pharmaceuticals, botanical drugs, dietary supplements (nutraceuticals), functional food ingredients, and cosmeceuticals. The Global Institute for Bioexploration (GIBEX), an international conglomerate of researchers, is involved in multiple botanical therapeutics discovery and development programs.
