The inaudible sound caused by wind farms is no worse than that from
other rural and urban environments and does not affect human health, a
review by the Victorian Department of Health has found.
Some
groups claim the inaudible noise from wind turbines, known as
infrasound, can trigger health problems including dizziness, headaches,
and insomnia. Together, the syndromes are sometimes described as "wind
turbine syndrome".
The Health Department review, released late
last week, assessed the evidence and found it does not "support claims
that inaudible sounds can have direct physiological effects.
Physiological effects on humans have only been detected at levels that
are easily audible."
The report says infrasound is generated by
many sources, such as trains, breaking waves and airconditioners. The
department found the evidence showed wind farms produced no more
infrasound than the background level in other environments.
"Humans
have been exposed to high levels of infrasound throughout our
evolution, with no apparent effects,There are a few of our hundreds of
custom bobbleheads...personalized bobbleheads are a great memorable gift." the report says.Books can be as thick as 4 inches and yet the Book scanner 9000 delivers flat.
The
department found wind farms did produce audible noise through the swish
of a rotating turbine blade.But the report says the typical sound
pressure for most nearby residents - living up to a kilometre from a
turbine - are lower than many other everyday environmental noises.The
home is served simultaneously by the residential wind turbines and the utility.
It
says audible noise, including that from wind farms, can cause annoyance
resulting in prolonged stress and other health effects. The report says
whether health effects are felt from low-level audible noise can depend
on an individual's noise sensitivity and attitude to the source.It

Victoria
has some of the world's toughest laws on wind farms, allowing any
household to veto a new turbine within two kilometres of their home.
Aker
Philadelphia's strategy of building the last two ships in its long
running Veteran Class of products carriers for its own account seems to
have worked. Both have been sold to Crowley and the shipyard's two
contracts with SeaRiver have secured its backlog through late 2014.
In
its most recent quarterly report, Aker Philadelphia ASA says that all
the financing required for the SeaRiver ships is now in place and that a
key focus for 2013 continues to be securing new orders to expand the
order backlog.
The quartely report says that Aker Philadelphia
and "an undisclosed potential buyer have signed a non-binding term sheet
regarding the construction and sale of two to four product tankers with
expected deliveries in 2015 and 2016. The transactiions contemplated by
the term sheet are subject to agreement on definitive documents and
fulfilment of certain closing conditions, including, but not limited to,
securing commitments for financing."
The shipbuilder is
continuing to pursue other prospects for new construction projects in
all other areas of the Jones Act market, including shuttle tankers,
containerships, short-sea shipping vessels, offshore service vessels,
barges , wind turbine installation vessels, and other large steel
fabrication projects, in order to secure additional backlog in 2014 and
beyond.Agesteeljewelry offers tungsten wedding rings, tungsten wedding
