Back Extraction Clause Samples

Back Extraction. Organic acids, nitrogen-containing compounds, phenolic compounds, and amino acids were removed from ILs by back extraction with aqueous solutions, making the necessary pH adjustments and the ILs were then quantitatively recovered after neutralization and evaporation of the solvent. For example, neutral nitrogen-containing compounds were recovered from [Bmim][Cl] by back extraction using water or methanol (Xie et al, 2008) and a 94-98% recovery of ferulic acid from [Bmim][PF6] was achieved with a 0.02 M NaOH aqueous solution (▇▇ et al., 2007). In another case, 99% of phenols present were removed from [Bmim][PF6] after back extraction with 0.1 mol L-1 NaOH aqueous solution (Fan et al., 2008) and amino acids were recovered from AAILs by adjusting the pH of the solution to 7.0 with HCl, thus neutralizing the amino group (▇▇▇▇ et al., 2010).

  • INTERIM MAINTENANCE PERIOD During the interim maintenance period between obtaining of the completion certificate of such Project and formation and operationalization of the Association the Promoter shall through itself or through a facility management company to run, operate, manage and maintain the Common Areas. The Promoter shall endeavour that the committee responsible for the maintenance and operation of the Common Areas will be required to provide manpower for maintaining the Common Areas, wherever required, and to collect maintenance charges and also guest charges and the user charges for the utilities being provided on “pay by use” basis, if any. The maintenance and management of Common Areas by the committee will primarily include but not limited to maintenance of water works, common electrical installations, DG Sets, landscaping, driveways, parking areas, lobbies, lifts and staircases, AMC’s etc. It will also include safety and security of the Project such as fire detection and protection and management of general security control of the Project. The Rules/ Bye Laws to regulate the use and maintenance of the Common Areas shall during the interim maintenance period shall be framed by the Promoter with such restrictions as may be necessary for proper maintenance and all the Allottees are bound to follow the same. After the Common Areas of the Project are handed over to the Association, the Association may adopt the Rules and the Bye laws framed by the Promoter, with or without amendments, as may be deemed necessary by the Association.

  • Access Toll Connecting Trunk Group Architecture 9.2.1 If WCS chooses to subtend a Verizon access Tandem, WCS’s NPA/NXX must be assigned by WCS to subtend the same Verizon access Tandem that a Verizon NPA/NXX serving the same Rate Center Area subtends as identified in the LERG. 9.2.2 WCS shall establish Access Toll Connecting Trunks pursuant to applicable access Tariffs by which it will provide Switched Exchange Access Services to Interexchange Carriers to enable such Interexchange Carriers to originate and terminate traffic to and from WCS’s Customers. 9.2.3 The Access Toll Connecting Trunks shall be two-way trunks. Such trunks shall connect the End Office WCS utilizes to provide Telephone Exchange Service and Switched Exchange Access to its Customers in a given LATA to the access Tandem(s) Verizon utilizes to provide Exchange Access in such LATA. 9.2.4 Access Toll Connecting Trunks shall be used solely for the transmission and routing of Exchange Access to allow WCS’s Customers to connect to or be connected to the interexchange trunks of any Interexchange Carrier which is connected to a Verizon access Tandem.
