Winning research project enhances reservoir water quality in Oman
Dr. Mohammad Nikoo mentioned that in arid locations such as the Sultanate of Oman, improving the quality of water released from reservoirs is a challenge.
This study, focused on Wadi Dayqah Dam, aimed to develop reliable operational guidelines for releasing water that meets downstream quality and quantity requirements.
Dr. Mohammad and his research team aimed to improve reservoir water quality, identify vulnerable outlets and optimal release strategies, and enhance resilience to climate change impacts.
Using a combination of multi-objective optimisation (NSGA-II), the CE-QUAL-W2 model, and Artificial Neural Networks (ANN), the research team simulated and optimised water withdrawal strategies.
A Robust Decision-Making (RDM) framework identified vulnerable outlets and water release ratios under various climate change scenarios.
The findings of the study revealed that activating multiple reservoir outlets reduces pollutant concentration and improves water quality.
Also, water released from low and mid-level outlets is more vulnerable to pollutants compared to surface outlets, and a strategic release of smaller volumes from lower outlets and larger volumes from upper outlets enhances operational stability and robustness.
Through this study, Dr. Mohammad recommended adopting flexible and optimised water release strategies under changing climate conditions to ensure reliable water delivery. The study was published in the Journal of Hydrology in 2024 with an impact factor of 6.4.
The research team consist of Dr. Mohammad Reza Nikoo, Ms. Nafiseh Bahrami, Prof. Kaveh Madani, Dr. Ghazi Al Rawas, Dr. Sadegh Vanda, and Prof. Rouzbeh Nazari.
Regarding his win, Dr. Mohammad Nikoo stated that 'winning the National Research Award is a significant honour that highlights the relevance and impact of our research. It inspires me and my team to continue working on innovative solutions that address critical water and environmental management challenges. It is also a recognition of our collective efforts and encourages us to contribute further to science and society.'

Oman to produce medical diagnostic machines locally
A strategic Memorandum of Understanding (MoU) was signed by Dr Mohammad Mahmoodi, CEO of Carbon Technologies, and Dr Frank Vitzthum, Board Member and CTO of R-Biopharm, Germany, in the presence of Dr Rahma bint Ibrahim al Mahrouqiyah, Minister of Higher Education, Research and Innovation, on Tuesday. Under the MoU, advanced diagnostic manufacturing will be localised in Oman, supporting technology transfer and enhancing the country's health innovation ecosystem. The partnership will enable integration of state-of-the-art assay technologies into its local production lines, supporting both national and regional healthcare priorities. 'It is a milestone MoU in Oman's journey towards eliminating tuberculosis and other diseases from the country, and both communicable diseases and NCDs,' said Dr Rahma bint Ibrahim al Mahrouqiyah, Minister of Higher Education, Research and Innovation. 'I'm optimistic and this will pave the way for various scientific advancements in the country, especially when it is located near SQU and within the Innovation Park Muscat. We have begun, and we look forward to having an international consortium to eradicate both communicable and non-communicable diseases. We look forward to collaborating with regional, national and international partners so that we can cooperate with the leading players,' she added. Speaking to the Observer, Dr Mohammad Mahmoudi, Chief Executive Officer of Carbon Technologies, said that this collaboration is a testament to Oman's growing capacity in innovation-driven industries and its strategic openness to global partnerships. 'Together with R-Biopharm, we aim to elevate diagnostic standards, nurture Omani talent and contribute to national healthcare resilience,' Dr Mohammad added. Aligned with the objectives of Oman Vision 2040, the MoU supports national goals in biotechnology, scientific research and industrial innovation. Speaking on the sidelines of the signing ceremony, Eng Said bin Nasser al Salmi, Board Member of Carbon Technologies, said that the MoU would open up more opportunities to leverage Carbon Technologies as a leading Omani company and expand local R&D capabilities to serve both domestic and international markets in the healthcare industry and position Oman among the leading innovation hubs in such sectors. Dr Dirk Dressler, Head of Business Development at R-Biopharm AG, said, 'We are honoured to partner with Oman's Carbon Technologies. This collaboration reflects our confidence in Oman's capabilities and our shared commitment to delivering high-quality, accessible diagnostics across the region."

Forum in Muscat trains students in advanced research methods
Muscat – The fourth edition of the Research Skills Forum began on Sunday at Arab Open University Muscat bringing together chosen postgraduate students from across Oman for two weeks of training in advanced research methods. Organised by Ministry of Higher Education, Scientific Research and Innovation, in cooperation with Arab Open University, the event will run till August 21. It is aimed at enhancing the research capacity of students from universities and science colleges. Haitham bin Saleh al Yarubi, Research and Innovation Capacity Building Specialist at the ministry, said the forum is part of ongoing efforts 'to develop the research skills of graduate students and empower them with modern scientific research tools and methods, in line with Oman's efforts to enhance the research and innovation environment'. He said this year's programme focuses on 'mixed research', an approach that combines quantitative and qualitative methods. 'We received 220 applications from researchers in various institutions,' he said. 'After screening according to specific criteria, 80 participants were selected and divided into two groups of 40 each.' The ministry plans to expand the scope of the forum in future editions to include broader fields and a larger pool of researchers. Dr Hamad bin Hilal al Yahmadi, Dean of the College of Education at the Arab Open University, said hosting the event was part of the university's commitment 'to create a stimulating environment for researchers and provide the academic support necessary for the success of such events, in partnership with the ministry'. Over the two weeks, participants will attend seminars and interactive sessions on the applied aspects of hybrid research, including study design, research management, data collection and analysis, and the publication of scientific results.
