Characterization of Ultrasonic Precursor Solution Spraying for Battery Material Synthesis
The effects of various conditions on the operation of an ultrasonic atomizer for battery material precursor solution spraying were investigated. The diameter of the droplets formed from this device was expected to roughly match that of the orifices from which they originated; however, two distinct modes of operation were observed for ejection from arrays of 17 ÎĽm and 55 ÎĽm orifices: 1) orifice-size dependent jetting and 2) generation of a mist of small droplets (\u3c 10 ÎĽm), the size of which was frequency independent. Experiments were conducted at the first and second half-wave resonances of a 1.2 mm high chamber (0.63 and 1.05 MHz respectively), though extensive characterization was limited to the second resonance. In most cases, the flow rate was proportional to applied voltage on the piezoelectric drive, after a threshold amplitude was exceeded. The ability to generate sub-10 ÎĽm droplets from larger orifices was not expected, but this capability should prove advantageous for the production of atypical battery materials by spray pyrolysis
Barley Culture in South Dakota
1. Barley ranks fourth in total production among the cereal crops in South Dakota. 2. Experiments upon which statements in this bulletin are based were conducted at the state college experiment farms at Brookings, Cottonwood, Eureka and Highmore and the U. S. Department of Agriculture experiment farm at Newell. 3. In general, barley has proved to be the highest producing small grain crop, though there have been some notable exceptions. 4. No advantage has been found in growing barley in mixtures with oats or emmer. 5. Odessa S. D. 182 gives good results in all parts of the state where tried and is recommended as the general purpose barley for the state as a whole. Other varieties are recommended for special conditions. 6. Using the best seed obtainable is good practice. Poor seed means poor stands and low yields. 7. Rust, smut, ergot, stripe disease and blight are among the important barley diseases. Control measures include early seeding, seed disinfection and grading and the rotation of crops. 8. Barley responds readily to good rotation methods. 9. The seed bed for barley should be firm with a shallow mulch at the surface. 10. Early seeding is very important. Six pecks per acre is generally the best rate of seeding. The proper depth of seeding is about 2 inches. Seeding with a drill is recommended. 11. Barley can be grown as· a cultivated crop to good advantage in sections where corn is not a highly profitable crop. 12. Careful shocking and stacking is strongly recommended in order to secure grain of good market quality
The Indianapolis Foundation Library Partners
In 1989 an anonymous bequest of nearly 25 million and producing approximately 16 million in grants to Marion County libraries. This resource in turn fostered a
collaborative environment among the libraries and librarians in Marion County that is also unique. In this article we describe the history of The Indianapolis
Foundation Library Partners, its current programs, and its growth over the years
Translanguaging and Bilingual Learners: A Study of How Translanguaging Promotes Literacy Skills in Bilingual Students
This study was conducted in order to research the impact that the use of translanguaging strategies has on bilingual learners and discovered whether or not these strategies supports their English language development. Data was collected during lessons taught, interviews with students and teachers, questionnaire feedback, and participation in a collegial circle. Findings revealed that translanguaging did promote the growth of students’ English language development. Findings also showed that teachers use various translanguaging strategies in their classrooms, but only some are confident about the positive effects of these strategies. Implications from this study indicated that teachers need to be formally trained in using translanguaging, and supported in their use of these strategies in alignment with current language policies and programs

Modeling of bone conduction of sound in the human head using hp-finite elements: Code design and verification
We focus on the development of a reliable numerical model for investigating the bone-conduction of sound in the human head. The main challenge of the problem is the lack of fundamental knowledge regarding the transmission of acoustic energy through non-airborne pathways to the cochlea. A fully coupled model based on the acoustic/elastic interaction problem with a detailed resolution of the cochlea region and its interface with the skull and the air pathways, should provide an insight into this fundamental, long standing research problem. To this aim we have developed a 3D hp-finite element code that supports elements of all shapes (tetrahedra, prisms and pyramids) to better capture the geometrical features of the head. We have tested the code on a multilayered sphere and employed it to solve an idealized model of head. In the future we hope to attack a model with a more realistic geometry
Expression and function of ryanodine receptor related pathways in PCB tolerant Atlantic killifish (Fundulus heteroclitus) from New Bedford Harbor, MA, USA

The definitive version was published in Aquatic Toxicology 159 (2015): 156-166, doi:10.1016/j.aquatox.2014.12.017.Atlantic killifish (Fundulus heteroclitus) thrive in New Bedford Harbor (NBH), MA, highly contaminated with polychlorinated biphenyls (PCBs). Resident killifish have evolved tolerance to dioxin-like (DL) PCBs, whose toxic effects through the aryl hydrocarbon receptor (AhR) are well studied. In NBH, non-dioxin like PCBs (NDL PCBs), which lack activity toward the AhR, vastly exceed levels of DL congeners yet how killifish counter NDL toxic effects has not been explored. In mammals and fish, NDL PCBs are potent activators of ryanodine receptors (RyR), Ca2+ release channels necessary for a vast array of physiological processes. In the current study we compared the expression and function of RyR related pathways in NBH killifish with killifish from the reference site at Scorton Creek (SC, MA). Relative to the SC fish, adults from NBH displayed increased levels of skeletal muscle RyR1 protein, and increased levels of FK506-binding protein 12 kDa (FKBP12), an accessory protein essential for NDL PCB-triggered changes in RyR channel function. In accordance with increased RyR1 levels, NBH killifish displayed increased maximal ligand binding, increased maximal response to Ca2+ activation and increased maximal response to activation by the NDL PCB congener PCB 95. Compared to SC, NBH embryos and larvae had increased levels of mtor and ryr2 transcripts at multiple stages of development, and generations, while levels of serca2 were decreased at 9 days post-fertilization in the F1 and F2 generations. These findings suggest that there are compensatory and heritable changes in RyR mediated Ca2+ signaling proteins or potential signaling partners in NBH killifish.Funding was provided through the NIEHS Superfund Research Program
