    Poems for Artizein

    This is a collection of seven poems all of which have to do with being a teacher or an observer of artistic growth in children, one\u27s self, or the differently abled. I view the teaching of art as something of a spiritual quest for greater understanding of the self and the world. I hope to have conveyed a bit of the essence of what it means to unfold in this regard

    Gauging the Importance of Microhabitat in Qualitative Macroinvertebrate Sampling in an Effluent Dominated Stream

    In the past different sampling strategies have been used to relate macroinvertebrate assemblages with habitat quality in the Sangamon River, above and below the sanitary district effluent discharge in Decatur, IL. The standard 20 jab method of proportional sampling in multiple microhabitats, based on QHEI physical habitat score, sampled allowed for comparison between sites based on overall community composition. However, it oversampled fine sediments, which dominate the Sangamon, therefore potentially missing sensitive taxa in isolated quality habitats. In the fall of 2016 I tested an enhanced qualitative approach to better gauge the importance of microhabitat types to macroinvertebrate assemblages in the river. We sampled five different natural microhabitats (riffles, fine sediments, root wads, snags, leaf packs) and 2 artificial substrates (Hester Dendy samplers, artificial leaf packs) at seven different sites. Sampling a subset of specific microhabitats allow for comparisons between sites, capture of sensitive taxa, and identification of specific habitats important in reclamation efforts. Non-metric multidimensional scaling (NMDS) in conjunction with a PERMANOVA and two-factorial MANOVA tests showed there were significant differences in assemblages between microhabitat types and between upstream and downstream sampling sites. Results indicate that root wad microhabitats are distinct from other microhabitat\u27s assemblage structure because they harbor more sensitive taxa than any other microhabitat thus making it an ideal habitat to sample in this system. However, microhabitat assemblage structure was found to be heavily influenced by physical factors (QHEI and flow) overshadowing any potential effects of water quality alteration provided by the effluent. Ultimately, changing the flow patterns of the Sangamon to replicate a more temporal-based/natural regime, rather than the current altered one, would in turn minimize variation in physical factors between sampling sites

    Post-traumatic cilia remaining inert in the anterior chamber for 50 years: a case report

    <p>Abstract</p> <p>Introduction</p> <p>The present report concerns what is, to the best of our knowledge, the first case of post-traumatic cilia that has remained inert for approximately 50 years after its inoculation into the eye.</p> <p>Case presentation</p> <p>A 69-year-old Caucasian woman whose right eye had been struck by a dining fork approximately 50 years earlier was examined on presentation two years ago. In her right eye, both uncorrected and best-corrected visual acuities were 0.1 (in decimal notation). Along with a nuclear cataract, a straight linear extension was found extending beneath the iris at the nine o'clock position reaching the center of the pupil, which appeared to be a cilium measuring 7 mm. After the removal of the cilia, an uncomplicated phacoemulsification was performed and a posterior chamber intra-ocular lens was implanted. Her post-operative course was uneventful, and visual acuity remained 1.0 for the 22-month follow-up period.</p> <p>Conclusions</p> <p>Intra-ocular cilia can be tolerated for as long as 50 years without causing any ocular reaction.</p
