Design is about people creating

solutions that help or improve

the lives of other people

Design is not an art although

there is art in it

Presentation Design is the proper arrangement in

space and time of images,

words and numbers

Wires not harnessed to prevent

contact with housing

Short circuit to ground created

where wire contacted housing

In summary, the detector failed because of a short-

circuit created by the abrasion of wire insulation

Systems with low herbivory (“top-down control”)

Primary production is mainly controlled by

nutrients availability

favourable climatic conditions (“bottom-up control”)

Examples

Lagoon of Venice and North Europe coastal zones

show macroalgae blooms

eutrophication

high concentrations of nutrients

Some systems have high nutrient concentrations in the water column

But other systems have low nutrient concentrations in the water column
