Moura Photovoltaic Power Station a capacity of producing 24 MW of solar panels annually. Moura Photovoltaic Power Station The Moura Photovoltaic Power Station (also known as Amareleja Photovoltaic Power Station) is a large photovoltaic power station in Amareleja, in the municipality of Moura, Portugal. It is one of the largest power stations of its kind, and is built in one of the sunniest regions in Europe. Its construction involved two stages: stage 1 was completed in 2008 after 13 months, and stage 2 was completed in 2010. The entire project topped a total cost of €250 million. Stage 2 of the project involved the
Injective module proved a useful result, usually known as Baer's Criterion, for checking whether a module is injective: a left "R"-module "Q" is injective if and only if any homomorphism "g" : "I" → "Q" defined on a left ideal "I" of "R" can be extended to all of "R". Using this criterion, one can show that Q is an injective abelian group (i.e. an injective module over Z). More generally, an abelian group is injective if and only if it is divisible. More generally still: a module over a principal ideal domain is injective if and only if it is divisible
