SPECIFIC INJURIES
Hip injuries
Overview and approach — Hip injuries are less common in runners than
injuries to the lower extremity and they can be difficult to diagnose.
Nevertheless, during jogging, the hip joint is subjected to loads up to
eight times body weight and both acute and chronic injuries can occur [55].
In runners, the differential diagnosis of hip pain includes gluteus medius
tendinopathy, piriformis syndrome, stress fracture of the femoral neck,
labral tear, a... 阅读全帖

想学wc style mogul skiing很久了,迟迟没有起步是因为其他要提高的太多,总觉得
没有ready,这是我滑雪以来进步最快的一个雪季,但这个计划外的camp给我带来了最

BARCELONA, Spain — Few opponents are able to slow down Barcelona's squad of
stars, but Nike may have inadvertently managed to do just that — with
shirts that absorb too much sweat.
The Spanish champion says it has recently met with Nike officials to
complain about the first team's new shirts absorbing so much moisture that
they take on added weight over the course of a game.

It really depends on what kind of control you want and what kind of power

There are three factors affect control:
1. the dwell time - how long the ball stay contacting the string bed. the
longer the better for those hit flat or simply ding the ball back.
2. the deformation of the string bed. this factor matters when the ball is
hit off centered so it bounces unevenly. the smaller the racquet head, the

La Mer has two types of eye cream. I forgot the names. One of them is light
green, the other is creamy white.
The lighg green is better because it is less oily and can be easily absorbed
. The creamy white is too rich (my opinion) and you need to message it to be
absorbed.
Both do no wonder.
I would recommend La Praire (the caviar series), although it is double the
price. It will last at least three months.

For detection of protein peak you can use UV absorbance at 260nm. Most
protein has intrinsic absorbance at this wavelength.
For the column, since your protein is big, you can use either Sephedex G-100
(usable for proteins of 40~150kD) or Sephedex G-150 (usable range up to
300kD)or any gel filtration column that can fit your protein.
Since you are not familiar with the chromatophraphy, I suggest you to
collaborate with a protein lab and ask them to do it for you, or at least
assist you to do it.

More than 99.99% of light is reflected. The rest goes into tissue and gets
absorbed. A very tiny is able to penetrate through, depending on the
thickness and composition of the tissue. Water is a major absorber. In
medial optics, the 600-900nm range is employed because water has weak
absorption and light is able to go deeper in the tissue. It is called "

Titanium
dioxide is a photocatalyst that generates reactive oxygen species (ROS), but
it requires ultraviolet light. Lead sulfide (PbS) quantum dots have a
narrow band
gap, allowing them to tune the absorbed wavelengths of the nanotubes to the
near infrared. To ensure singlet oxygen generation, the photoreactive NO
donor

Sure. many other possible functional groups absorb where S-C absorbs. so be
very careful...

Human's digestive system cannot absorb vitamin C together with its so-called
"其他成分有机地结合成(一个)整体". Even if you eat fruits and vegetable,
the vitamin C molecule absorbed in guts is no different from that coming
from a pill.

There had been an ongoing controversy over health effects of electromagnetic
fields (EMF) for years (e.g., extremely low frequency radiation and the
Navy's Project Seafarer; emissions of high power lines and video display
terminals; radar and other military and industrial sources of radio
frequencies and micr... 阅读全帖

Yes!
Definitely, graphene and CNT have wide applications.
In my field: passively mode locking fiber lasers,several companies have used
CNT to mode lock fiber lasers and generate high power fs pulses.
CNT based saturable absorber has become commercialized.
Moreover,similiar to CNT, graphene could also be used as ultra-fast
universial saturable absorber which could mode lock lasers at any wavelength.
If you feel interested, you could visit wiki website of graphene:

Glass's band gap is about 9 eV. The energy of visible lights range from 1 eV
to 4 eV and they can not be absorbed by glass. Other materials' band gap
and phonon spectrum are very small and then those lights will be absorbed
in this case.

The correct answer should be 10. We have three states here and the
transition matrix is:
4/5 1/5 0
0 4/5 1/5
0 0 1
with the third state an absorbing state.
Let Q=[4/5 1/5; 0 4/5], inv(I-Q)=[5 5; 0 5]. And we start from the first
state, so the expectation time that we arrive at the absorbing state is 5+5=

Use Markov Chain, 15-20 are absorbing states, calculate the absorbing
probabilities.
