F.D.E. Fire Damage Investigation

F.D.E. Fire Damage Investigation

Steel structures may experience a temporary decrease in the performance of the steel material due to heating, which can lead to deformation under the applied loads.

When the scale of the fire is large and the temperature experienced by the structure is high, the concrete may lose strength due to heat, and gaps may form between the materials, causing separation between the rebar and the concrete.

Activity Project Manta

Activity Project Manta

Collect valuable data on manta rays, which have rarely been studied, and cooperate in building a foundation for long-term monitoring of their habitat.

Looking to the future, manta rays could become an excellent indicator species for monitoring environmental changes in the world's oceans and coral reefs due to their widespread distribution and easily recognizable appearance. Global warming has caused significant changes in the state of the Earth's oceans. All changes, such as variations in sea temperature, ocean current patterns, and ocean acidification, could have dramatic consequences for manta ray distribution, migration, and behavior, as well as for the coral reefs that support their lives. Investigating the relationship between manta ray distribution and migration and large-scale ocean changes will help researchers monitor and assess the health of the oceans on Earth.
