Ship demolition activity

The association between demolition activity and children's blood lead levels.

Urban renewal efforts are a priority for many American cities. As efforts to reconstitute urban centers increase, the demolition of old, deteriorated structures has accelerated. Recent studies have identified demolitions as a potential source of environmental lead exposure. We conducted a study examining the relationship between demolition activity and blood lead levels of children residing in ...

Caspases: cellular demolition experts.

Apoptosis is co-ordinated by a family of cysteine proteases, the caspases, that dismantle the cell by targeting a panoply of proteins for limited proteolysis. The mammalian caspase family contains 14 members, a subset of which participates in apoptosis, with the remainder likely to be involved in the processing of pro-inflammatory cytokines. Apical caspase activation events are typically initia...

Interactive Structural Demolition

We present a method for a structural simulation of destructible 3-dimensional metal frame buildings at interactive frame rates. Beams, floor slabs, and wall sections are simulated as rigid bodies and joined together by rigid constraints. Each constraint is given a set of breaking thresholds for the force and torque around each axis, allowing them to fail if the structure is overloaded or damage...

Construction and demolition waste indicators.

The construction industry is one of the biggest and most active sectors of the European Union (EU), consuming more raw materials and energy than any other economic activity. Furthermore, construction waste is the commonest waste produced in the EU. Current EU legislation sets out to implement construction and demolition waste (CDW) prevention and recycling measures. However it lacks tools to ac...
