Evaluación Del Efecto Antimicrobiano Del Polvo Y Extracto Acuoso Liofilizado De Hojas De Moringa Oleífera En Un Derivado Cárnico (Chorizo Crudo), Natalia Ximena Munevar, Erika Paola Zambrano Orozco

Ingeniería de Alimentos

El interés en la búsqueda de extractos vegetales que tengan poder antibacteriano frente a microorganismos patógenos, ha permitido que el presente trabajó de investigación tenga como propósito evaluar la actividad antimicrobiana de la extracción acuosa liofilizada y el polvo de las hojas deshidratadas de la especie vegetal Moringa oleífera frente al crecimiento de Staphylococcus aureus. El extracto acuoso se obtuvo por el método de cocción a partir de las hojas deshidratadas, para posteriormente ser sometido a liofilización. El polvo se consiguió moliendo las hojas deshidratadas para disminuir el tamaño de partícula. Se evaluó la actividad antimicrobiana del extracto acuoso liofilizado …

The Effect Of Behavioral Traits And Background On Engineering Students’ Decision-Making Process Compared To Business Students, Joe Scott

Williams Honors College, Honors Research Projects

This paper looks to narrow down the reasons that students undertake new credentials, specifically in sales fields. With a focus on character traits and upbringing, the goal is to ensure that there is a better understanding of the reasons that people undertake these credentials. The different benefits of credentials will be analyzed to determine the most influential reason that people would be willing to move forward. The combination of these factors will be used to provide recommendations of the best way to reach and influence the decision of the engineering students.

The motivation of this study is to investigate the size dependent properties of Gadolinium silicide nanoparticles and their potential applications in Biomedicine. We use two approaches in our investigation - size dependence and possible exchange interaction in a core-shell structure. Past results showed Gd₅Si₄ NPs exhibit significantly reduced echo time compared to superparamagnetic iron oxide nanoparticles (SPION) when measured in a 7 T magnetic resonance imaging (MRI) system. This indicates potential use of Gd₅Si₄ ferromagnetic nanoparticles as T2 contrast agents for MRI.

Until recently most contrast agents (CA) that are used in Magnetic Resonance …
