Hi-Tech Helmet Heads Off Stroke Damage
A helmet placed on the head of a stroke victim sends low-intensity microwaves through the brain to quickly determine whether a blockage or hemorrhage is taking place, making faster treatment possible. Wayt Gibbs reports

When a person suffers a stroke quick treatment is crucial. But there are two very different kinds of strokes: some result from blood clots that block circulation within the brain, others are caused by ruptured vessels that spill blood into surrounding tissue. The use of clot-busting drugs when a hemorrhage is happening can cause additional injury or death. So doctors lose precious time waiting for stroke victims to get MRIs or CAT scans before they start treatment.

But soon EMT’s might be able to quickly tell whether patients have a blockage or a bleed—by having them wear a high-tech helmet.

Researchers at Chalmers University of Technology in Gothenburg, Sweden developed the prototype helmet and tested it on 45 stroke patients.

The gadget covers the head with a patchwork of antennas. As each antenna beams low-intensity microwaves through the head in sequence, the other antennas detect how the waves scatter. Any pooling blood from a hemorrhage causes deflections easily spotted on an attached computer. The research is in the IEEE Transactions on Biomedical Engineering. [Mikael Perrson et al, Microwave-based stroke diagnosis making global pre-hospital thrombolytic treatment possible]

Trials using mobile stroke helmets in ambulances are scheduled to start in the fall. As with proper treatment, the sooner the better.

the 3D tech may play a important role in near future.

main idea---60% is enough
2 eg:
football&basketball--better until 60%--overlap
comparison:
baseball--- the more the better----speicalized


main idea---ice are increasingly scouring, altering a lot of species
reason: temperature rise---shallow--invertebrate animals comes out to hurt native---cannot recover/some invert monopoly


main idea: explain the 1910 flu
reason: young didn't exposed to such flu, so they are vulnerable
further study: russia flu led some people to have immumme, so they cannt infect with spanish flu

mian idea: 1910 flu is related to the 1900 seasonal flu
structure:
significance: help future study
BG: seasonal flu may domainate 10 years
explaination: birds move--- people get flu

attitude: hopeful
reason: gather together to develop a universal vaccine to treat with all kinds of flu

main idea: 3D models help are&pal a lot
stucture:
Question about if the tech can make it same?
Answer is yes
advantageous about tech in arche:
1. preserve site
2. save time& money
worries:
1. lose in the museum---online more
2. data theft---international rules
attitude: optimistic&hopeful

Speed:

The flu in 1800s, the disease became pandemic because of less exposure, so the new vaccine should let the people at the appropriate age get exposure.

Obstacle: 3 D technology to collect artefact data and solve the mastery fast and effective.

Examples:

China’s terracotta-ears and faces
Ancestor foot print

3D- advantage faster, affordable, available

time 2   1:19
It is not always the good thing to have elites as more as possible.
Researchs suggest that having 60% elites will be better for the team.

time 3   1:07
the huge influence that the scouring icebergs have on the sea floor

time 4   1:17
Scientists have found the reason why health young people was vulnerable in the 1918 flu.

time 5   1:32
Unlike old people,the youngs had not been exposed to flu strains more closely related to the 1918 flu, offering some immunity.

time 6   1:21
current situation of flu treatment
scientists are looking for a universal vaccine to protect all kinds of viruses.

quick treatment to stroke is important ,bur there are different kind of
strokes.some...others...can cause..even death,doctors don't have enough
time for...a technique EMT used...the theory of the technique and its
affection.

time 2 (240 works)1'22"
more elite players in a team ,better performance will be .only if the
proportion of the elite players in a team is no less that 75%.but there
is a limit to the proportion of the elite players in a team.For basketball
team,the ideal proportion is ....for soccer team, the proportion is ...and
the difference between those two is that elite players will compete to get
a point in a soccer team while elite players in basketball team is specialized.
so the idea of a coach that more elite players will improve the performance may
turn out wrong.

time 3 (219 words)1'34"
the color of WAP was used to be different ,because as winter come, there will
be a fast ice .however as the climate change day by day ,the fast ice becomes
more shadow,so the color of WAP change as well.Furthermore , with the change
of climate,animals are becoming endangered except one called...which will in turn
make the ice more vulnerable.


time 4 [235 words]1'17"
scientists announced on Monday that they had figured out the reason of flu in 1918,
which mostly killed young adults--older people born had suffered from similar flu,
so that they were immune to the 1918 flu.
in short ,"it is just a problem of timing."

time 5[284 words]1'45"
the flu in 1918 can date back to the 1907 flu.flu are seasonal.
doctors should use vaccine from people who survive from flus to protect
others from seasonal flu.

time 6[257 words]1'34"
the speed of flu  is different in different species.
if the flu in 1918 is seasonal, vaccine can be made to protect people who
have not been injected.but if the 1918 flu is unique in the ...chain,then
it is out of luck to survive from another flu.

passage 7 [910 words]
3D technology is becoming more and more popular  to collect and analyse
information,especially for  historic site.For example. the terra-cotta warriors
and the footprint many years ago.
the strength of the 3D technology are :cheap and easy to access.
the weakness of 3D technology is that some people may duplicate cultural relic
through the information provided by the 3D
all in all ,the wide application of 3D is just a matter of time.


maybe I should conclude more brief.
