Metamorphosis of Rubbish: Eduardo Paolozzi\u27s General Dynamic F.U.N.
This project incorporates the production of written materials that support a proposed art exhibit of curated selections from Eduarao Paolozzi\u27s General Dynamic F.U.N. print series, a holding in the Frances Young Tang Teaching Museum and Art Gallery\u27 s permanent collection. Included in this project are reproductions of the curated artwork, a catalog introduction, introductory wall text and exhibit labels, and four creative essays.
Eduardo Paolozzi was a forceful proponent in the 1950s-1960s of the appropriation of American pop cultural iconography for works of art. His work bridged formal Surrealism and the inception of the Pop Art movement in Britain. The exhibit labels and catalog introduction examine the historical, psychological, cultural, and philosophical contexts in which Paolozzi\u27s art developed. The essays were conceived as a means to lessen the distance between viewer and art by adding another layer of meaning to the exhibited prints
Acceleration Patterns During Standing and Running Tumbling Passes in Collegiate Cheerleading
Tumbling requirements and expectations of heightened difficulty of tumbling skills has grown to become a vital component in competitive collegiate cheerleading. Acceleration patterns during tumbling skills has been previously explored in gymnastics, with a floor routine being the most similar in nature, but not completely transferable considering differences in tumbling surface, execution strategy, and setting. Therefore, the purpose of this study was to investigate acceleration patterns during different tumbling passes in collegiate cheerleading athletes. Fifteen female collegiate cheerleaders (age = 19.6 + 1.50) participated in the study. Each participant completed a max of seven different tumbling passes (two standing, 5 running) with a tri-axial accelerometer attached via headband. Peak resultant linear acceleration (PRLA) and peak resultant rotational velocity (PRRV) were tracked and analyzed. Separate repeated measures ANOVAs were used to compare differences in PRLA across tumbling passes and between participant background, and PRRV across tumbling passes. For PRLA, there was a significant main effect for skill (p \u3c 0.001), and a significant skill by background interaction (p =0.045). For PRRV, there was a significant main effect for skill (p \u3c0.001). The hypothesis of the study was supported. The intermediate standing and running skills showed a significant lower PRLA and PRRV compared to advanced and elite standing and running skills. This supports previous research regarding contact hits from heading a soccer ball and non-contact acceleration patterns during gymnastic floor routines. The most common pattern in timing of PRLA and PRRV was during landing for standing tumbling skills, during the skill for intermediate running tumbling, and during the transition skill for advanced and elite running skills. The current study supported previous literature on task demand and acceleration patterns in tumbling, while expanding that literature to competitive cheerleading. Providing evidence that some skills generated less mechanical load on the body may assist with practice structure and safer injury management in competitive collegiate cheerleading. Future research should investigate acceleration patterns in competitive cheerleading at a larger scale involving multiple collegiate programs across the nation as well as expanding to youth cheerleading and all-star programs
Sonic levitation apparatus
A sonic levitation apparatus is disclosed which includes a sonic transducer which generates acoustical energy responsive to the level of an electrical amplifier. A duct communicates with an acoustical chamber to deliver an oscillatory motion of air to a plenum section which contains a collimated hole structure having a plurality of parallel orifices. The collimated hole structure converts the motion of the air to a pulsed. Unidirectional stream providing enough force to levitate a material specimen. Particular application to the production of microballoons in low gravity environment is discussed

Fine roots distribution, light conditions and yield in a tree-based intercrop system
Paper presented at the 13th North American Agroforesty Conference, which was held June 19-21, 2013 in Charlottetown, Prince Edward Island, Canada.In Poppy, L., Kort, J., Schroeder, B., Pollock, T., and Soolanayakanahally, R., eds. Agroforestry: Innovations in Agriculture. Proceedings, 13th North American Agroforestry Conference, Charlottetown, Prince Edward Island, Canada, June 19-21, 2013."In tree-based intercrop systems (TBI), trees are planted in widely spaced rows to allow agricultural activities to continue. These agroforestry systems are new in Qu_bec but well known in Europe, USA and China (Baldy et al., 1993; Rivest and Olivier, 2007). The integration of trees into an agroforestry system has the potential to enhance soil fertility, reduce erosion, improve water quality, increase biodiversity and aesthetics, and sequester carbon (Jose, 2009; Montagnini and Nair, 2004). However, the presence of trees also results in aboveground and belowground interspecific interactions with crop, which can include competition, facilitation or complementarity (Jose et al., 2004; Rivest and Olivier, 2007; Van Noordwijk et al., 1996). In theory, TBI systems can be more productive than the respective monocultures if trees have the capacity to take resources like water and nutrients in deeper soil layers than those used by crops (Cannell et al., 1996)."--Introduction.L�a Bouttier (1), Alain Paquette (2), Christian Messier (2) and Alain Cogliastro (1) ; 1.

Sustained expression of microRNA-155 in hematopoietic stem cells causes a myeloproliferative disorder
Mammalian microRNAs are emerging as key regulators of the development and function of the immune system. Here, we report a strong but transient induction of miR-155 in mouse bone marrow after injection of bacterial lipopolysaccharide (LPS) correlated with granulocyte/monocyte (GM) expansion. Demonstrating the sufficiency of miR-155 to drive GM expansion, enforced expression in mouse bone marrow cells caused GM proliferation in a manner reminiscent of LPS treatment. However, the miR-155–induced GM populations displayed pathological features characteristic of myeloid neoplasia. Of possible relevance to human disease, miR-155 was found to be overexpressed in the bone marrow of patients with certain subtypes of acute myeloid leukemia (AML). Furthermore, miR-155 repressed a subset of genes implicated in hematopoietic development and disease. These data implicate miR-155 as a contributor to physiological GM expansion during inflammation and to certain pathological features associated with AML, emphasizing the importance of proper miR-155 regulation in developing myeloid cells during times of inflammatory stress
