Timber-based hybrid structures provide a prospective solution for utilizing environmentally friendly timber material in the construction of midrise or high-rise structures. This study mainly focuses on structural damage evaluation type timber–steel structure that incorporates prefabricated light wood-frame shear walls into steel moment-resisting frames (SMRFs). The such was evaluated through sh...

This paper proposes an alternative to data integration from heterogeneous sources or databases. In some cases, inconsistencies may occur, and in others, the schema lacks of any attribute or entity to store the data. Some inconsistencies are consequence of using a language different with the one employed in the schema definition; others are due to the use of distinct units of measure. The object...

We predicted that, in Soberania National Park in central Panama, the proportion of experimental seedlings damaged by litterfall would be higher at forest edges than in the forest interior. Over a 16-week period during the rainy season, 41% of 1260 experimental seedlings...
