Hide right sidebar on specifik blog.

Hi, I’ve two blogs using the same theme and theme files.
But I want to remove the right sidebar in one blog.

Something like this..

<?php
                //Show sidebar
	        <div id="sidebar-right" class="right">
		      <?php include 'sidebar_ads.php'; ?>
	        </div>
		}
		elseif(BLOG_NAME == 'moa') {
                //If blogname "moa", then dont show.
		?>
