The Determination of Small Amounts of Trichloroethylene
In research studies on the extraction of soybean oil by trichloroethylene it became necessary to determine small amounts of the solvent in the oil. For amounts above 10 percent trichloroethylene the simplest and best method for control purposes is by means of a specific gravity determination. Measamer (3) has shown that the trichloroethylene may be steam-distilled from the oil and weighed or measured. Three percent trichloroethylene in soybean oil may be determined with a maximum error of 10 percent. Greater accuracy should be possible in solutions containing more of the solvent. For amounts above 10 percent the method is more time consuming and no more accurate than the specific gravity method
A Broadly Implementable Research Course in Phage Discovery and Genomics for First-Year Undergraduate Students
Engaging large numbers of undergraduates in authentic scientific discovery is desirable but difficult to achieve. We have developed a general model in which faculty and teaching assistants from diverse academic institutions are trained to teach a research course for first-year undergraduate students focused on bacteriophage discovery and genomics. The course is situated within a broader scientific context aimed at understanding viral diversity, such that faculty and students are collaborators with established researchers in the field. The Howard Hughes Medical Institute (HHMI) Science Education Alliance Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) course has been widely implemented and has been taken by over 4,800 students at 73 institutions. We show here that this alliance-sourced model not only substantially advances the field of phage genomics but also stimulates students’ interest in science, positively influences academic achievement, and enhances persistence in science, technology, engineering, and mathematics (STEM) disciplines. Broad application of this model by integrating other research areas with large numbers of early-career undergraduate students has the potential to be transformative in science education and research training

IMPORTANCE: Engagement of undergraduate students in scientific research at early stages in their careers presents an opportunity
to excite students about science, technology, engineering, and mathematics (STEM) disciplines and promote continued interests
in these areas. Many excellent course-based undergraduate research experiences have been developed, but scaling these to a
broader impact with larger numbers of students is challenging. The Howard Hughes Medical Institute (HHMI) Science Education
Alliance Phage Hunting Advancing Genomics and Evolutionary Science (SEA-PHAGES) program takes advantage of the
huge size and diversity of the bacteriophage population to engage students in discovery of new viruses, genome annotation, and
comparative genomics, with strong impacts on bacteriophage research, increased persistence in STEM fields, and student selfidentification
with learning gains, motivation, attitude, and career aspirations
