The hands-on exposure was most beneficial to CSIR-IMMT Bhubaneswar (13th - 14th June 2019) ~20 research scholars who attended the workshop. Ore & Minerals Analysis (OMA) Workshop is an annual event which is hosted periodically by M/s Malvern Panalyti- cal in different countries. The 14th OMA Workshop was jointly organized by M/s Malvern Panalytical and CSIR- IMMT, Bhubaneswar during 13th-14th June 2019 and for the first time, the workshop was held in Asia. The theme of the workshop was “Latest developments in X-ray tech- niques for minerals, metals, and materials”. A total of 74 participants from industry, academia, and R&D attended the workshop. Overseas experts from The Netherlands, Australia, Indian faculties from CSIR-IMMT, Institute of Physics, ICT-Mumbai and from the Malvern Panalytical provided both theoretical insights and practical demon- Intellectual Property Rights (IPR) A workshop on Intellectual Property Rights (IPR) Aware- ness was organized on 25th April 2019 (14:00 – 17:30) by the Department of Business Development of CSIR-IMMT. The resource persons were Dr. S.K. Kar and Dr. P. Karthigeyan of Intellectual Property Facilitation Centre (IPFC), Central Tool Room & Training Centre (CTTC). Head of Business Development Shri Santosh Mishra, Chief Scientist welcomed the gathering and explained the objec- tives of the program. A brief introduction on IPFC activities and IPR was presented by Dr. Kar, Head of IPFC. Subse- quently Dr. Karthigeyan explained in detail about different IPR concepts such as Patent, Industrial Design, Trademark, GI, Copy Rights. Later he presented on prior art Search, Patent drafting, Filing procedure and Fees (a case study), PCT filing, Technology Licensing, FTO analysis. The pro- gram winded up with a vote of thanks by Dr. A K Sahoo, Chief Scientist. Utkal Diwas Every financial year in CSIR-IMMT starts with a vibrant atmosphere due to “Utkal Diwas”, the Odisha state for- mation day on 1st April. Like earlier years, IMMT-Staff Club celebrated the Utkal Diwas of 2019 with great enthusiasm. Shri Trilochan Kanungo, an eminent educationist, econo- mist and ex-member of parliament from Odisha was the Chief guest on this occasion. The event was started in the traditional way by the lightening of the lamp and recitation of Odisha state song, “Bande Utkala Janani”. The director of the institute, Prof. S. Basu welcomed all the staffs & guests present in the function and narrated the history of the first instance of formation of provinces (Orissa and Sindh) based on language before independence.
