Figure 5 Dried After treatment, filtrate on Aluminium foil The results indicate a drastic decrease in the mass percentage vanadium loading in the recovered filtrate. The corresponding values highlighted in red show vanadium loading in the untreated solution (Figure 1) and the after-treatment filtrate (Figure 5). Analysis indicates Vanadium sorbed to coffee surface in Figure 4 and none in Figure 3. Conclusion(s) or Summary: The results indicate the strong potential for spent coffee grounds to act as an inexpensive sorbent to remove Vanadium from wastewater with no pH adjustment. Thus, sustainable feedstock could be the solution to an imminent global water scarcity problem.

Latin America's Musical origins and its Influence on "Suite Suramericana," an Original Composition
Brandon Bernal Mentor: Daniel Pardo Department of Music Abstract Latin-American music is a manifestation of the cultural merge of European forms, along with harmonic development, with the richness of African and Middle Eastern rhythms. This mixture of cultures resulted in the creation of new sounds and traditions in different geographical regions. This consideration goes beyond boundaries set by countries. In some instances, music styles are shared, as seen in Venezuela and Colombia's plains with Joropo and Musica Llanera, or the Andean music covering the mountain range from Chile and Bolivia, through Peru, Ecuador, and Colombia. There are other cases where geographical divisions kept the development of music styles within a specific country, but with branches so distinct that they become recognizable to the trained ear. That is the case of music from Brazil, where within its large territory, Samba and Choro have evolved differently throughout the country. This composition aims to create a work for two instrumental voices, inspired by the joining of musical genres from several regions and countries in Latin America with a modern approach to harmony and sound design. To accomplish this, we use traditional composition and forms and electronic composition Page practices 117 such as of 3
