  • The Postal Service Is Amending Mailing Standards of the United
    This document is scheduled to be published in the Federal Register on 10/11/2018 and available online at https://federalregister.gov/d/2018-22107 , and on govinfo.gov 7710-12 POSTAL SERVICE 39 CFR Part 111 POSTNET Barcode AGENCY: Postal Service™. ACTION: Final rule. SUMMARY: The Postal Service is amending Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM®) to remove all references to the POSTNET™ barcode. DATES: Effective Date: [INSERT DATE PUBLISHED IN THE FEDERAL REGISTER]. FOR FURTHER INFORMATION CONTACT: Lizbeth Dobbins at (202) 268-3789 or Garry Rodriguez at (202) 268-7261. SUPPLEMENTARY INFORMATION: The Postal Service published a notice of proposed rulemaking on July 23, 2018, (83 FR 34806–07) to amend the DMM to remove all references to the POSTNET barcode. This decision was based on the limited use of the POSTNET barcode and the need to simplify the standards in regard to barcoding letter-size and flat-size mailpieces. The Postal Service received 1 formal response which was in agreement with the removal of POSTNET barcodes in the DMM. The Postal Service will remove all references to the POSTNET barcode from the DMM. The Postal Service will continue to process mailpieces with a POSTNET barcode to accommodate customers who may have preprinted stock bearing a POSTNET barcode. List of Subjects in 39 CFR Part 111 Administrative practice and procedure, Postal Service. The Postal Service adopts the following changes to Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM), incorporated by reference in the Code of Federal Regulations.

JOVANOVI]# and MILICA MI[I]-VUKOVI]# Department of Organic Chemistry, Faculty of Technology and Metallurgy, University of Belgrade, Karnegijeva 4, P. O. Box 3503, 11120 Belgrade, Serbia and Montenegro (e-mail: [email protected]) (Received 14 May, revised 26 July 2004) Abstract: Rate constants for the reaction of diazodiphenylmethane with isomeric pyridine carboxylic acids were determined in chosen protic and aprotic solvents at 30 °C, using the well known UV spectrophotometric method. The values of the rate constants of the investigated acids in protic solvents were higher than those in aprotic solvents. The second order rate constants were correlated with solvent pa- rameters using the Kamlet-Taft solvatochromic equation in the form: log k =logk0 + sp*+aa + bb. The correlation of the obtained kinetic data were performed by means of multiple linear regression analysis taking appropriate solvent parameters. The signs of the equation coefficients were in agreement with the postulated reaction mechanism. The mode of the influence of the solvent on the reaction rate in all the investigated acids are discussed on the basis of the correlation results. Keywords: pyridine carboxylic acids, diazodiphenylmethane, rate constants, solvent parameters, protic and aprotic solvents. INTRODUCTION The relationship between the structure of carboxylic acids and their reactivity with diazodiphenylmethane (DDM) has been studied by many authors,1,2 with particular regard to the influence of the solvent.
