|In women, bone loss occurs rapidly in the perimenopausal years. It leads to osteoporosis this eventually progresses to bone damage or fractures without any pain or symptoms. Osteoporosis is a global health threat without prevention and treatment. In this case the bone becomes less dense, resulting in week bones. Calcium is considered to be the primary nutrient required for many of the body functions to run perfectly. Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is âself-archivingâ (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals. Open Access rises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
