  • Solo List and Reccomended List for 02-03-04 Ver 3
    Please read this before using this recommended guide! The following pages are being uploaded to the OSSAA webpage STRICTLY AS A GUIDE TO SOLO AND ENSEMBLE LITERATURE. In 1999 there was a desire to have a required list of solo and ensemble literature, similar to the PML that large groups are required to perform. Many hours were spent creating the following document to provide “graded lists” of literature for every instrument and voice part. The theory was a student who made a superior rating on a solo would be required to move up the list the next year, to a more challenging solo. After 2 years of debating the issue, the music advisory committee voted NOT to continue with the solo/ensemble required list because there was simply too much music written to confine a person to perform from such a limited list. In 2001 the music advisor committee voted NOT to proceed with the required list, but rather use it as “Recommended Literature” for each instrument or voice part. Any reference to “required lists” or “no exceptions” in this document need to be ignored, as it has not been updated since 2001. If you have any questions as to the rules and regulations governing solo and ensemble events, please refer back to the OSSAA Rules and Regulation Manual for the current year, or contact the music administrator at the OSSAA. 105 SOLO ENSEMBLE REGULATIONS 1. Pianos - It is recommended that you use digital pianos when accoustic pianos are not available or if it is most cost effective to use a digital piano.

Growth Trends and Projections The City is projected to grow to a population of about 6,000 by 2040, an increase of about 20% from 2020. However, there are concerns that such growth will not happen unless more land is made available for development and the community invests in its school facilities. The CET and Council identified investment in the schools as critical to continued private investment and growth in Columbus. They then paused the Roadmap 2050 process to allow the community to focus on a School District referendum to invest $30 million in school facilities.

  • Manual for Standard Pneumatic Shear Machine
    OPERATING MANUAL HM-381 & HM-381F Standard Pneumatic Direct Shear Machine INTRODUCTION The Gilson HM-381 Standard Pneumatic Direct Shear Machine is a tabletop unit that provides direct or di- rect/residual shear values for evaluating the strength and stability of soils. Manufactured in cooperation with Karol-Warner, this device utilizes a pneumatic loading piston for applying the vertical load to the sample. A calibration chart is included for setting the high load or the low load via the Fairchild Regulator while a built-in digital readout displays the vertical load in psi. This Direct Shear Unit has a strain rate of 0.0001 – HM-381 0.3 in/min (0.0025 – 7.62 mm/min) with a maximum shear displacement of 0.8in (20.3mm) and the travel Direct Shear Boxes & Accessories speed is set with the thumbwheels on the left side of Porous Description Shear Box Cutters Extruders Stones the unit. The residual shear force is determined by a Round Direct Shear Boxes load cell while real time load settings and peak load 50mm (1.97in) Diameter HMA-733M HMA-743M HMA-763M GSA-208 are displayed on the digital readout.

  • Josh Frankel Re 2016 Revaluation
    From: Josh Frankel < [email protected] > Sent: Thursday, August 18, 2016 2:37 PM To: Mayor Subject: Follow up to reval question Mayor Mark: I just sent the email below to Ms. Albanese, and hope that I might get the answer that proved so elusive last night. I do not consider this item closed by any stretch. Beyond that, I found Ryan's inability to address Michael Levine's questions (during both of his visits to the mic) extremely troubling. "The ends justify the means" is not how a reval should be done. Equally troubling was his claim that, apparently, no intermediate work product was ever retained, which defies common sense and probably USPAP and IAAO standards and guidelines. I hope you are as troubled by the substantive issues that were not closed out last night as I am. And I do not posit that rhetorically. Thanks for holding the meeting and getting Ryan to appear. If nothing else, perhaps it was a bit cathartic. Regards, Josh Sent from my iPad Begin forwarded message: From: Josh Frankel < [email protected] > Date: August 18, 2016 at 2:29:10 PM EDT To: Nanette Albanese < [email protected] > Subject: Follow up to reval meeting Nanette: I confess that I am a bit taken aback that you think I would disrespect you in any way. That is not, and has never been, the way I operate. I am trying to understand what happened with this reval and, frankly, I am more confused now than I was before I stepped to the microphone last night.
