0:00:08i wanted to talk about the research project more
0:00:13we
0:00:15that the
0:00:16on the scale
0:00:18the humorous known here
0:00:21we also a fever
0:00:25which is fine
0:00:27e o is
0:00:29have traditionally been measured using e
0:00:33the old fashioned the calibre i asked you met
0:00:38no major i met your
0:00:43some aspects of shape but in order to be able to see internal structure
0:00:50you have to actually do extracted analysis
0:00:54traditional
0:00:57i project university of tennessee
0:01:00we're we did c t scans of the contrast on a scale collection which
0:01:06a collection of modern humans
0:01:09people have deleted the results to study the actually decompose and i outside around or
0:01:17research facility
0:01:19a natural conditions so whenever at a rate
0:01:25the so everything is affecting these skeletons some of them are very but what we
0:01:32end up with
0:01:34are
0:01:35set of a remains skeletal remains that
0:01:38can be a
0:01:41and that sort of backwards fast so we know
0:01:46there are we there are sex their column huh
0:01:54we can kind of backwards to see what are able to tell about that things
0:01:59are was interested by
0:02:01so what about l one
0:02:06relies we may not know where the despite our problems are constantly changing shape
0:02:11and they change due to repetitive motions or practice and that way but not just
0:02:17the joint actually can change the shape the shaft
0:02:21and
0:02:23for forces you putting on a compressed for so that was really like praat using
0:02:29compressive force on the bones has would be had weights for or body
0:02:39you need to increase the boundary area portable structure and syllables have to constantly remarkably
0:02:45in order to attach to are changing a have a sterilised
0:02:50and so
0:02:52what i think that we can do we can look at internal structure we see
0:02:56how strong that cross section it how much surface area there is it actually tells
0:03:01us how probable the sweet more backwards if we were friends the case we have
0:03:10a scale that's
0:03:11that we find in what we want to find out
0:03:14this person what's so as far as the rest joe who is using a program
0:03:20called amir a
0:03:22we have access to this impressive database that c t stands that are very high
0:03:28resolution and we're using this program that is able to create three dimensional
0:03:35a circus models of the bones but we're doing extra sentences and internal sources so
0:03:40we can see that cross section at any point or without having about
0:03:44and a
0:03:46i'm here it is
0:03:47harper very robust analyses but it is comparable but it so if there any potential
0:03:52donors that there we are looking for work is still working on a free trial
0:03:58version a mere
0:04:00and it's a lecturer show how this program is what we are able to do
0:04:04with
0:04:05so you're using a program for your
0:04:09what is it takes
0:04:11c d c and slices lancelot so we can look at all it conceivable so
0:04:19what i with all it is
0:04:22i will like it out you can see structure inside and out from their arrival
0:04:28three people
0:04:31to switch phones i want
0:04:34from their computer will comply
0:04:37all sources speech
0:04:40and i just three model you can be just any that you want to
0:04:47and
0:04:48observe any changes in the bone
0:04:52any formally safer stress on the ball from here what we can you is
0:05:01manager
0:05:03the link
0:05:06of the ball
0:05:08and we can also find here from each slice
0:05:13c t scan
0:05:15and that will help us
0:05:17understand the density of nicole slice by slice so we can look at and understand
0:05:24how the sum here as
0:05:27from this we can understand
0:05:30what has and affecting the bonn
0:05:34what are not manage problems with say or person is we orders so from that
0:05:41we're using that to do about forty it's got all remains in your looking
0:05:48just the body mass index our least it's
