Sri Lanka Natural Sciences Rankings 2024

Agriculture and Forestry, Art, Design and Architecture, Business and Management, Economics and Econometrics, Education, Engineering and Technology, History, Philosophy, Theology, Law, Medicine and Health Sciences, Natural Sciences and Social Sciences and their 256 sub-branches can analyse the world, countries and regions. You can also analyse them according to i10 index and citation numbers. *Jul 17, 2024 According to Total H Index. BETA VERSION. Subject field ranking in world, region, country and university is beta version since subject field 'others' (652.491) scientists profile whose branch cannot be determined, not yet edited or determined) is excluded, so the ranking will change as the others fields are edited.
