Hi there I'm John Bond from Riverwinds Consulting and this is Publishing Defined.

Today I'm going to talk about institutional repositories. An

institutional repository is an archive for collecting preserving and

disseminating digital copies of the intellectual output of an institution

These archives exist to provide ready access to institutional research output

by self archiving in an open access fashion and to give global visibility to

an institution's scholarly research as well as to preserve its digital assets

Institutional repositories might include monographs scholarly journal articles

both as preprints or post prints theses dissertations conference proceedings

research to digital assets such as datasets learning objectives and many

other formats. The material might be text-based

video or other formats.In my opinion an institutional repository should be

focused institution wide instead of topic specific. Institutions operating

a repository are committing to the long term preservation of all materials for

future generations. Institutions gain obvious benefits from maintaining such

an archive both internal as well as to the wider community. All institutional

repositories should be registered with ROAR or the registry of open access

repositories which is a searchable international database indexing the

location of open access repositories and their contents the Confederation of Open

Access Repositories or COAR has discussed the importance of connecting

and tying together repositories an important part of this is achieved by

using a common open standards such as OAIPMH or the open archives

initiative protocol for metadata harvesting also many institutional

repositories are using a common platform namely BePress Digital Commons Bepress

was recently acquired by Elsevier. Institutions many times have

internal rules governing them such as mandatory depositing of specific

materials in a set period of time institutional repositories play a

valuable role in the archiving and dissemination of scholarly communication

and research as the world moves more toward an open knowledge approach as

opposed to a subscription-based one these repositories should only grow in

importance and prominence. Well that's it I'm a publishing consultant and work

The Van Allen Belts Are Lethal, This Is How Astronauts Fly Through Them - Duration: 3:26.

There's an invisible, magnetic force field surrounding our planet, protecting us from

harmful solar wind that could annihilate Earth.

But, this protective blanket is also a swirling ring full of deadly radiation.

And to leave Earth's atmosphere, astronauts have to pass through it.

The Van Allen belts are rings of energetically charged particles that have been captured

by Earth's magnetic field.

They got their name from this physicist, James Van Allen.

Back in the 1950s, Van Allen launched a rockoon, a rocket lifted by a balloon above the atmosphere,

and it detected the first hint of radiation at higher altitudes.

Then, Explorer 1, the first American satellite to orbit Earth, launched in January 13, 1958.

Explorer 1 confirmed that Earth's magnetosphere was trapping the subatomic particles.

The Van Allen belts were the first major scientific discovery of the early Space Age, and they

posed a serious challenge for space travel.

High speed subatomic particles can tear through DNA, increasing the risks of cancer and other

diseases.

So sending astronauts through these particles is not ideal, and even though they're flying

in a shielded spacecraft, doses of radiation can still seep through.

But there's no way around the Van Allen belts.

In order to reach space, astronauts have to travel through the inner belt, which is comprised

of protons, and then through the outer belt, which has mostly high energy-electrons.

One solution, proposed by Mr. Van Allen himself, suggested detonating a nuclear bomb in the

inner belt to clear out radiation.

While Van Allen's plan wasn't executed, in 1962, the United States did carry out a

nuclear test in space, dubbed Starfish Prime.

They wanted to see if detonating a 1.4 megaton bomb in low-Earth orbit could augment and

expand the Van Allen Belts, but the explosion actually ended up adding more radiation around

our planet.

So, for the Apollo missions, NASA had to create a radiation barrier within the spacecraft

and figure out a trajectory that avoided the thickest, most radioactive part of the belts

while traveling as fast as possible.

Scientists determined that if the speed of the apollo spacecraft was about 25,000 kilometers

per hour, it would take a spacecraft about 52.8 minutes to pass through the belts.

Scientists found that the radiation dose received during that amount of time would be, at most,

11.4 rads and that's without the protection of a spacecraft.

A lethal radiation dosage for a human is 300 rads in one hour, so NASA deemed the missions

a go.

After all that, it turned out, that during the Apollo missions, the average radiation

doses on the skin of the astronauts came out to be 0.38 rad which is about the same radiation

you would receive getting two CT scans of your head.

So while the Van Allen belts are lethal, they could really only kill an astronaut if they

were to spend several days in their radioactive vicinity.

And despite the challenges the belts create when leaving Earth, we should actually be

thanking them for protecting life on our planet from utter annihilation.
