Since the beginning of the century, many cities around the world adopt the bus rapid transit (BRT) system to fulfill their need of mass transportation system. The system features with platform-level boarding, bus lanes in the central verge of the road, off-vehicle fare collection, and physically protected busway. So far, these criteria are considered to be the most important aspects with respec...

Soil organic carbon (SOC) sequestration through the application of amendments (OAs) is considered an important strategy to offset anthropogenic CO2 emissions while simultaneously enhancing soil quality and food security. The efficiency SOC sequestration, however, depends on priming effect which influenced by interactions OA composition with microbial response variables (MRVs). Yet, there remain...

Efforts to renew marine ecosystem monitoring include advanced technology and cost-effective methods have been repeatedly called for. The current environmental legislation in European Union (EU) requires also beyond the scope of conventional sampling strategies. Despite several studies showing benefits new methods, progress adopt national programmes under legal requirements has slow. In this stu...
