| Abstract | A novel method for micro bubble manipulation by ultrasonic waves is proposed. This method uses seed bubbles in order to manipulate the target bubbles. First, if the seed bubbles are introduced into an incident ultrasonic wave field, they start to oscillate, radiating secondary ultrasonic waves around them. These waves produce Bjerknes force between the bubbles. This produces seed bubble aggregation with a certain size. Then, the target bubbles are introduced, the Bjerknes force between the aggregated seed bubbles and the target bubbles trap the target bubbles, producing a bi-layer bubble mass of (inner layer: seed bubbles, outer layer: target bubbles). Experiments are carried out using bubbles with PVC shells. It is observed that the target bubbles, which are not trapped when they flow into the ultrasonic wave field, are trapped as a bi-layer bubble mass by the proposed method. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
