High intensity focused ultrasound (HIFU) is a noninvasive treatment technique to induce thermal or mechanical bioeffects.Characterising the wave field is essential for reliable and reproducible transducer operation in clinical use.This paper presents a schlieren technique to visualise and quantify transducer wave fields.The technique is based on th
Abstract Bacterial adherence to the intestinal epithelium plays a role in niche establishment in the gut lumen.Through sampling natural populations of Caenorhabditis, we discovered several bacterial species that adhere to the intestinal epithelium via polar, intimate association, best described as attachment.These bacteria had varying effects on 5.
