[Solved] conflict between Jquerys

I find the solution .The solution is to use noConflict function like that :

<script>
var jq172 = jQuery.noConflict();
jq172(document).ready(function()
{
   var jQueryTabs1Opts =
   {
      event: 'click',
      collapsible: false
   };
   jq172("#jQueryTabs1").tabs(jQueryTabs1Opts);
}); 
</script>
