Engineers from RMIT University have invented a protective coating for concrete pipes that could help drastically reduce the formation of fatbergs in sewers.
Fat, oil and grease (known as FOG) – infamous for solidifying inside pipes and concrete sewers – causes half of all sewer blockages in the United States and 40% in Australia. The cost of these blockages in terms of maintenance and rehabilitation is estimated at US$25 billion in the US and A$100 million in Australia per year.
Global carbon emissions from fossil fuels have reached a record high in 2024, according to new research by the Global Carbon Project science team.
The airflow from an indoor badminton court’s HVAC system and cross ventilation can affect the path of a birdie and have a significant role in play, but research published in Physics of Fluids proposes that different roof configurations could help mitigate wind drift. The authors recommend that important badminton games be played on courts with a barrel roof and a ventilation opening. The team modeled the airflow in a barrel roof stadium with different ventilation opening directions and tested this against a simulation of a flat roof to understand the roof effects.
Destructive winds during storms and cyclones often cause tree failures, especially through uprooting and stem breakage. However, how trees respond to wind under various forest configurations and weather conditions remains unclear. A recent study on Cryptomeria japonica plots shows that trees dissipate wind energy by switching between two swaying behaviors at specific wind speeds, offering insights that may help in improved forest management to minimize damage caused by storms.
