    MAIN.HTM 10/13/2006 06:42 PM +1. INTRODUCTION These are comments to "Additional Cyrillic Characters In Unicode: A Preliminary Proposal". I'm examining each section of that document, as well as adding some extra notes (marked "+" in titles). Below I use standard Russian Cyrillic characters; please be sure that you have appropriate fonts installed. If everything is OK, the following two lines must look similarly (encoding CP-1251): (sample Cyrillic letters) АабВЕеЗКкМНОопРрСсТуХхЧЬ (Latin letters and digits) Aa6BEe3KkMHOonPpCcTyXx4b 2. CYRILLIC LETTER RUMANIAN YN In the late Cyrillic semi-uncial Rumanian/Moldavian editions, the shape of YN was very similar to inverted PSI, see the following sample from the Ноул Тестамент (New Testament) of 1818, Neamt/Нямец, folio 542 v.: file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 1 of 28 MAIN.HTM 10/13/2006 06:42 PM Here you can see YN and PSI in both upper- and lowercase forms. Note that the upper part of YN is not a sharp arrowhead, but something horizontally cut even with kind of serif (in the uppercase form). Thus, the shape of the letter in modern-style fonts (like Times or Arial) may look somewhat similar to Cyrillic "Л"/"л" with the central vertical stem looking like in lowercase "ф" drawn from the middle of upper horizontal line downwards, with regular serif at the bottom (horizontal, not slanted): Compare also with the proposed shape of PSI (Section 36). 3. CYRILLIC LETTER IOTIFIED A file:///Users/everson/Documents/Eudora%20Folder/Attachments%20Folder/Addons/MAIN.HTM Page 2 of 28 MAIN.HTM 10/13/2006 06:42 PM I support the idea that "IA" must be separated from "Я".

Abstract The response of flexible pavement is largely influenced by the resilient modulus of the pavement profile. Different methods/approaches have been adopted in order to estimate or measure the resilient modulus of each layer assuming an average modulus within the layer. In order to account for the variation in the modulus of elasticity with depth within a layer in elastic pavement analysis, which is due to temperature or moisture variation with depth, the layer should be divided into several sublayers and the modulus should be gradually varied between the layers. A powerful and innovative computer program has been developed for elastic pavement analysis that overcomes the limitations of the existing pavement analysis programs.

  • Orion 3A Manual
    Orion-3A Pneumatic Pressure Controller Part #55287, Patent No. 4.698.998 SPECIAL FEATURES: • Orion 3A is a variable volume pressure controller with on operating pressure from vacuum to 10,000 psi. It consists of two low torque, fine micro-metering valves with positive shut-off, adjustable stop and soft seat. The pressure valve controls the inlet pressure and the other valve vents to atmosphere. • The vernier is located at the center of the controller and allows the operator a very fine pressure adjustment (approx. ±5% point max.) without using the pressure or vent valve. • Selecting the appropriate O-ring material may extend the wide range of gas applications. • There is one inlet, one outlet, and two test ports. One test port may be used to connect a pressure transducer or pressure gage standard; the other test port may be used to connect the unit under test. OPERATION: The pressure valve will begin to open when it is turned counter clockwise approximately 15 degrees. Full open position of the valves is achieved with a maximum of 3 1/2 turns from the closed position. Use the pressure/vent valves to achieve ±95% of the target pressure. The pressure and vent valves must be closed before operating the vernier. The vernier is a piston and cylinder configuration, which generates ±5% pressure, or vacuum of the indicated pressure. The vernier has a fine adjustment sensitivity of .005 psi. Very low torque is required to turn the vernier... FINGERTIP ADJUSTMENT EVEN AT 10,000 psi!!!!! SPECIFICATIONS: • Pressure Range: 0-10,000 psi and Vacuum • Proof Pressure: 15,000 psi Precision Precision Pneumatic Controller • Pressure & Vent Valve Orifice: .032 • CV: .007 • Mechanical Rotation: 3 1/2 turns (nom.) • Torque: Fingertip adjust (even at 10,000 psi) • Vernier Volume: .4 cubic inch (nom.) • Mechanical Rotation: 15 turns (nom.) • Adjustable sensitivity: .005 psi • Construction: 300 Series stainless steel body, aluminum knobs, black anodize.

HOWARD A. ZUCKER COMMISSIONER OF HEALTH TO: NEW YORK STATE CEMETERY BOARD FROM: LEWIS A. POLISHOOK, Director CC: ANTONIO MILILLO, Counsel DATE: JULY 22, 2020 RE: PINELAWN MEMORIAL PARK, NO. 52-044 INSTALLATION OF LAWN CRYPTS By application dated July 8, 2020, Pinelawn Memorial Park (the Cemetery) seeks confirmation that the New York State Cemetery Board does not object to its application to develop additional lawn crypts adjacent to a section of lawn crypts approved by the New York State Cemetery Board on December 11, 2018. The Cemetery is the largest regulated cemetery in New York. It consists of 786 acres spanning Wellwood Avenue, and is located in the Town of Babylon, in Suffolk County. It has a series of mausoleum buildings, but is primarily a memorial park, although it also has lawn crypt sections and sections with upright markers. The cemetery appears to be in compliance with all Division regulations; the cemetery is consistently well-maintained and generates few lot owner complaints. The Cemetery maintains a conflict of interest policy. No related parties are involved in this transaction. An excerpt from the Cemetery’s most recent 990 showing compensation is included as an exhibit. Summary of Recommendation The Division recommends approval of the project. The cemetery has a demonstrated track record of selling such burial spaces profitably, and has built them before, so it is familiar with the additional engineering requirements of lawn crypts.

I greatly appreciate his patience and the encouragement he provided to help me focus on the work. I would also like to thank my thesis committee members Dr. Mihai Marasteanu, Dr. Henryk K. Stolarski, and Dr. Douglas M. Hawkins for their help and valuable feedback on this dissertation. The financial support provided by the Minnesota Department of Transportation and the Federal Highway Administration (FHWA) Transportation Pooled Fund Study TPF-5(149) ―Design and Construction Guidelines for Thermally Insulated Concrete Pavements‖ is deeply acknowledged. Special thanks to all my fellow students for making memories that I will cherish forever. Last but not the least, I am most grateful to my husband, Amit for his love and support during this time. I am forever thankful to my loving family. i To my parents ii ABSTRACT An asphalt concrete (AC) overlay of a jointed plain concrete pavement (JPCP) is intended to extend the service life of the existing pavement structure. Also known as composite pavements, such pavements exhibit features of both rigid and flexible pavements. While behavior of rigid pavements is mainly elastic, behavior of asphalt layer is load-duration dependent.
