Hi, Chi:<br /><br />Please see attached for the&nbsp;final edited document. Thank you for allowing&nbsp;me some extra time. You have, I believe, a very nice paper, but please proofread carefully. &nbsp;Although I tried not to change the content -- only the flow -- sometimes a material change does occur.<br /><br />Now, I'll have a cup of coffee and then start on your second paper.<br /><br />I hope my revisions help.<br /><br />MS Word includes tracked changes by default. Before sharing this document, please consider running Inspect Document. To do this, click File/Info/Check for Issues/Inspect Document on the Microsoft Word menu bar.<br /><br />Best wishes - George<br /><br />I am usually available for editing between 6:00 am and 10:30 pm (EST). If my status says 'unavailable', you can still reach me via Editor World.
