Generational Views On Cars and Public Transportation

In an America where cars reign supreme, it may be a surprise to learn that some people dislike driving. Cars have long represented the American dream and our cultural values of individualism and freedom; for some, they are a social status symbol representative of wealth or personality (Griffith and Marion 2020, 310). In this research project, we set out to explore how older and younger people in our community perceive cars and public transportation in order to try to determine if this cultural value, and the role that cars play in America\u27s cultural heritage, are changing

Detailed Analysis of a Contiguous 22-Mb Region of the Maize Genome

Most of our understanding of plant genome structure and evolution has come from the careful annotation of small (e.g., 100 kb) sequenced genomic regions or from automated annotation of complete genome sequences. Here, we sequenced and carefully annotated a contiguous 22 Mb region of maize chromosome 4 using an improved pseudomolecule for annotation. The sequence segment was comprehensively ordered, oriented, and confirmed using the maize optical map. Nearly 84% of the sequence is composed of transposable elements (TEs) that are mostly nested within each other, of which most families are low-copy. We identified 544 gene models using multiple levels of evidence, as well as five miRNA genes. Gene fragments, many captured by TEs, are prevalent within this region. Elimination of gene redundancy from a tetraploid maize ancestor that originated a few million years ago is responsible in this region for most disruptions of synteny with sorghum and rice. Consistent with other sub-genomic analyses in maize, small RNA mapping showed that many small RNAs match TEs and that most TEs match small RNAs. These results, performed on ∼1% of the maize genome, demonstrate the feasibility of refining the B73 RefGen_v1 genome assembly by incorporating optical map, high-resolution genetic map, and comparative genomic data sets. Such improvements, along with those of gene and repeat annotation, will serve to promote future functional genomic and phylogenomic research in maize and other grasses

Angle Iron Profile Rotator

Design and validate a system that can rotate various angle iron profiles in a conveyor system. Angle irons are initially positioned with their longest leg resting on the conveyor system. It is needed to rotate it certain degrees until it forms the ^ shape. That is, the ends of the legs touch the conveyor system. The angle irons can be of different lengths (10’ to 40’). The design and validation must be done through engineering calculations (e.g., dynamical analysis and/or finite element analysis). Finally, a small-scale proof of concept is needed as a deliverable, in addition to the design and validation explained above
