while weeds in sugar beet farming reduce crop yield and quality, they also lead to higher labor and material losses. in recent years, in order to eliminate or reduce the damage caused by weeds in sugar beet farming, weed control has gained importance. to this end, various studies have been conducted on robotic weed control by detecting weeds using image processing algorithms and hoeing or spray...

We consider definably compact groups in an o-minimal expansion of a real closed field. It is known that to each such group G is associated a natural exact sequence 1→ G00 → G → G/G00 → 1 where G00 is the “infinitesimal subgroup” of G and G/G00 is a compact real Lie group. We show that given a connected open subset U of G/G00 there is a canonical isomorphism between the fundamental group of U an...

This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...
