Chemical and Physical Analyses of Synthesized Silver Nanoparticles
No full textAlthough silver has long been used as an antimicrobial agent, it is not used often due to economical and environmental concerns. However, silver nanoparticles (AgNPs) have the same properties as elemental silver and can be synthesized on a considerably more economical level. The objective of this study was to synthesize AgNPs and analyze their physical, chemical, and antimicrobial properties. The first portion of this study consisted of synthesizing AgNPs of 5nm, 35nm, 40nm, and 60nm lengths, using diluted lab solutions and sterile techniques. The physical analysis of the AgNPs was performed through visual color comparisons of their varied sizes, which confirmed their successful synthesis. A chemical analysis was then conducted using ultraviolet-visible spectroscopy, which measured their absorbance at a 635nm wavelength. Finally, the antimicrobial property of the AgNPs was investigated by inoculating a strain of Staphylococcus aureus with titrated concentrations of varied nanoparticle size. This titration allowed for the analysis of the relationship between the size of AgNPs and level of inhibition of S. aureus. The results of the bacterial inhibition were quantified using a colorimeter, which determined the density of the bacteria and the consequent level of inhibition. The results were analyzed using an ANOVA test, which determined that at a 95% significance level, AgNPs were successfully able to inhibit the growth of S. aureus. However, the results of an ensuing series of t-tests indicated that there was not a consistent relationship between the size of the nanoparticles and the level of bacterial inhibition
Héritages de Mallarmé. Paul Morin et René Chopin
Get PDFHéritages de Mallarmé. Paul Morin et René Chopin
Cette communication s’appuie sur un constat : contrairement aux poèmes de Baudelaire et de Rimbaud, l’œuvre de Mallarmé ne semble pas avoir exercé un ascendant significatif sur les poètes canadiens-français qui, au début du XXe siècle, ont contribué au développement de la modernité littéraire. Faut-il conclure pour autant que l’auteur du « Coup de dés » n’a pas été lu? Certainement pas, puisque les poètes associés à la revue Le Nigog (1918), dont quelques-uns seront qualifiés d’ « exotiques » en raison de leur opposition au régionalisme, s’y réfèrent parfois explicitement. Tel sera l’objet principal de cette communication, qui tentera de mettre en lumière l’héritage direct et indirect de Mallarmé chez deux poètes de cette génération, soit Paul Morin (1889-1963) et René Chopin (1885-1953). Il s’agira d’évaluer dans quelle mesure le lexique qu’ils emploient et l’esthétique qu’ils élaborent révèlent l’existence d’une filiation mallarméenne au Québec. À défaut de conclure que Mallarmé a eu une influence déterminante dans l’histoire de la modernité québécoise, il sera possible de voir comment son héritage est perceptible dans certains poèmes de Morin et de Chopin qui seront commentés brièvement
A Survey of the Phenomenological Research of Listening to Preaching
No full textThe preaching literature overflows with normative definitions of preaching – preachers ought to do this, because this is what Paul, or Jesus did. The listener has been understood as a constant, whom the preacher sought to educate and persuade. Against this backdrop an interest developed in what listeners “do” with sermons. A new vein of homiletical research followed – namely the phenomenological study of what listeners “do” when hearing sermons. Within this vein is the Dutch/German practical theological research, highlighting how sermon themes, life situation, the preacher’s connectedness to the congregation, or how listeners’ personality type affect engagement with the sermon. Conversely there arose American liberal arts driven homiletics, utilizing communication or rhetorical frameworks to understand what listeners are doing. This paper reviews all the phenomenological research from both fronts, and attempts to summarize, highlight the recurring themes, and clarify the points of tension and difference therein
