Continuous FN stimulating burr by means of the StimBurGard system is a safe and effective tool for FN stimulation and identification. The integrity of FC is preserved in most cases when the stimulation intensity is 1 mA.

This research aims to highlight the obstacles to green buildings and reveal the factors that can help in reducing these obstacles. It uses a qualitative approach and collects data from previous studies. The results highlight that the literature on green buildings mentions barriers and obstacles in different categories, including financial, governmental, organizational, management, operational, technical, and socio-cultural barriers. Most of these barriers, directly and indirectly, affect the development of green buildings. To overcome these barriers, there are some important factors to be considered, including the introduction of new government rules and regulations, offering incentives to industry to encourage businesses, creating a collaborative culture among stakeholders to spread awareness and knowledge, information regarding green building, ensuring the sharing of success factors, and sharing of critical cases to add knowledge to others. Emphasis on these factors or strategies can help in the development of green buildings, which will lead to sustainable development in Saudi Arabia. Project managers can consider these results as guidelines to ensure sustainable development.
