The Norwegian government awarded UMaine and the Norwegian University of Science and Technology (NTNU) about $292,000, or approximately 3 million Norwegian krone, to develop new, collaborative learning and research opportunities between both the institutions in the area of offshore wind. This 4-year grant was allocated through the UTFORSK program, which is funded by the Norwegian Ministry of Education and Research and administered by the Norwegian Directorate for Higher Education and Skills. The project award will be shared equally among both the institutions.
Through the collaborative project with NTNU scientists, UMaine researchers also plan to revamp five courses and create two new ones that includes a course on floating offshore wind turbines and one course on Marine Operations. Additionally, the multi-institutional team plans to establish four virtual summer intensive classes taught by faculty from both universities.
Researchers from both institutions also aim to prepare two externally funded project proposals and publish more than 10 international research articles together as part of this joint effort. They also plan to establish monthly virtual online seminars with guest lectures and panel discussions starting in January 2023, and two joint seminars held during conferences in 2024 and 2026.
Verma says part of the rationale behind the collaborative project is that the offshore wind industry is rapidly growing worldwide and is recognized as one of the most important strategic areas by Norway and the U.S. Both NTNU and UMaine have a wide range of common research and educational activities in the area of offshore wind technology, thereby formulating a sound basis for a partnership that will advance the growth of next-generation offshore wind infrastructures.
For Verma, the joint effort between his current home institution and his alma mater will be crucial, as this will allow him to work with students and his previous colleagues at NTNU while advancing the research goals of his Wind Energy and Marine Operations (WEMO) Lab.
Verma holds his PhD (Business Administration) and MS (Engineering) from University of Utah (USA) and his bachelor of technology from Indian Institute of Technology, Kanpur (India). He has published over 75 articles in prestigious academic journals and has also written numerous reports for the industry audience. He regularly presents his research, participates in invited panel discussions, and delivers keynote addresses at major industry and academic conferences around the world.
Dr. Verma has more than three decades of experience in programmatic research and evaluation in the area of family planning and reproductive health, gender mainstreaming and HIV/AIDS in India and countries throughout Asia.
He has significant experience and background in social sciences and social demography, which enables him to understand the micro and macro dimensions on the issues of men and masculinities, reproductive health, family planning, gender-based violence, HIV/AIDS and economic development. This unique combination of skills in research, as well as designing and evaluating innovative models, allows him to bring to ICRW critical aspects of examining norms that are deeply embedded in human behavior and social phenomenon. He particularly enjoys mentoring and nurturing a team of young aspiring researchers.

Following a stroke, a surge of ATP is released from compromised brain cells. This surge, in turn, triggers a cascade of events, including the activation of neurons and microglial purinergic receptor P2X4 (P2X4R). This activation facilitates rapid excitatory neurotransmission through the influx of cations. However, excessive activation of P2X4R can lead to the release of several pro-inflammatory cytokines during the initial stages of ischemic injury. Interestingly, the effects of acute activation stand in contrast to those observed with chronic inhibition or the absence of this receptor. In fact, prolonged inhibition or the lack of P2X4R might hinder the process of stroke recovery. Thus, acknowledging the dual role of P2X4R in different phases of ischemic injury, we are currently engaged in a systematic exploration of its potential as a therapeutic target for enhancing post-stroke recovery. In essence, our research endeavors revolve around deciphering the intricate role of P2X4R, recognizing its potential as a double-edged sword in stroke-induced processes. Through a comprehensive understanding of its temporal dynamics, we aim to pave the way for innovative therapeutic interventions that can tip the balance in favor of improved recovery outcomes.

Tonsillectomy is a major surgical procedure in terms of volume in the general otolaryngological practice. It is a 3000-year-old surgical operation, referred in Hindu medicine. There has been a conceptual change in the indications and surgical technique in the last 40 years. A comparative study between the various methods of tonsillectomy was done. The study was carried out in the single institutional set up by the same surgeon but using different techniques. The study aimed at comparing the intra-operative factors (blood loss, time taken for surgery), postoperative results (pain, bleeding, dehydration, time taken for complete healing), and other complications like vomiting and hospitalization time between different groups of surgical methods. This study was done in 2500 patients undergoing tonsillectomy with or without adenoid removal in a period of 35 years (1979-2013). The majority of the patients (approximately 41%) in the first half of this period underwent cold steel tonsillectomy whereas 39% underwent microdebrider assisted tonsillectomy. Microdebrider assisted tonsil surgery was done as day care procedure in 90%. In 21% of the patients, other methods viz coblation, radio frequency and laser were used. Microdebrider intracapsular tonsillectomy is associated with lower mortality and morbidity as compared to cold steel, coblation, electrodissection, laser and radio frequency.
