Microbubbles provide an effective and inexpensive method of detection for biofilm-based infections and other diseases such as cancer. The approach studied here examines the potential of targeted microbubbles, with specific antibodies covalently linked to their surfaces for use as ultrasound contrast agents and drug delivery vehicle. This work presents a novel numerical model for estimating the forces on microbubble conjugates in the vascular system. A full computational fluid dynamics simulation of biological fluid flow and the resulting forces on attached microbubbles is presented as well as comparisons with simplified analytical models. Both the computational and analytical predictions are compared with experimental measurements from Takalkar et al. and Schmidt et al., and these comparisons indicate stable microbubble attachment can be anticipated when the total hydrodynamic force on the microbubbl...

However, language anxiety will be experienced by students in learning speaking. The research is aimed to know students’ perception of language anxiety in speaking skill. The learners’ perception of language anxiety deserve a special mention as it is one of the parties directly involved in learning process. This study explores learners’ perceptions of language anxiety in speaking classes at one of the university in Cimahi. This study involved thirty five students from Indonesian Language Department as sample. To collect the data the researchers used numerical likert scale in the questionnaire by Dornyeiand Taguchi (2010: 150) with thirteen questions. From the results, most of students felt the various anxieties when they speak; for example being laugh at by other students when they make mistakes, and most of students feel ashamed if they got bad grades in English.
