 doing rocket science, but it's about diligence and teamwork for trying to complete the project successfully. And for that, we have the library part where we were getting weekly discussions and reports about the projects. Each student was reporting the amount of work that he did for the project and trying to come up with the plan for the upcoming weeks. So the next important part of my trip was to get some comments from Dr. Rodriguez for our prototypes because there were many small nuances that we couldn't understand as we don't have a medical experience. So for example, large modifications to the handle. Could we shortly just emphasizing that this comment came from a surgical practitioner and they are very important, very important details. For example, first one that there should be some slanted cut that would repeat the profile of the bone. You can see that here this part is removed. Another comment that was done that there should be some rounded end here that was also done and then this comes from my experience as a mechanical engineer in the field of machine tool design. Here I defined very close fits. Actually here the comment was that they don't fit close fits. They fit loser fits, which is better, which is less expensive from production point of view. Then as I mentioned they use x-rays during the surgery and the comment or suggestion was to make this part from that part from radio loosened material so that during the surgery it allows to see inside the leg. So this is not actual because we are just now are concentrated on the nails themselves. And then as I described there should be a special hammer but for inserting the nail and removing the nail when unfortunately there are cases that they need. It should be designed also. The important thing is to compare as we said and we compare the original part, Sintas model with our part through finite element analysis. So this is the model of the finite element analysis. We hold the bone. You see it is a bit transparent. You can see the nail and the screw, proximal screw within the bone. We hold the bone system from this part and we apply force from the tip of the heat and we see how it behaves. And we can see them separately. So this is the picture, the stress field in the bone and this is the stress field in the nail and screw. Of course here the models are simplified because it will take a lot of memory from computer too. And this is underway. We compare the models. One important aspect of comparison is related to so-called stress shield. The point is that the nail should not be too strong to take the complete load on itself. Something should be left also to bone for the bone not to degrade. And now this comparison, this red one is Sintas. Dependence of the stress over bone from stress over nail. This is this relation and this blue one is ours. So we see that they are closed but this is still underway. And as a conclusion, a couple words of conclusion. The first thing I want to mention that this is a nice experience of long term collaboration. I should say that we found some kind of fertile ground. Because the problem is a real problem because it's a very important problem for us. And because there are mutual willingness to do this problem, to complete it successfully. The next important thing that we have a good feeling, I cannot say still confidence. But it is a good feeling that the local production of this product is possible. Why not confidence yet? Because the real production should differ significantly from the production that have in our vision. A real production for consumers, for patients. So many things are done but much more still should be done. And many things are done within, as I said, these walls. But the project, if we to achieve the goal and the objective should have to go outside these walls. A lot of things to be done. And first of all, the weakest component in this project is the business component. Without market analysis, without business plan, we will not succeed. So that's it. If you have questions, then we will be happy to answer them. Questions or comments? I have two questions. I have two questions. One of them concerns, have you done any corrosion tests on the materials used or is it just on literature? My second question is, I am aware that there are some materials which may cause, I'm not sure if it's the correct term, there are allergic reactions or that type of reactions with some patients. Are there any guidelines to allow you to select which materials can be used, which could be used, or that's all? This is a well-known grade of titanium that is used in medical applications, particularly in this kind of implantation. So maybe Ara will give a more competent answer to this question. So as part of the first, as we followed the STM guidelines, STM specifies what kind of materials you cannot use in testing. And these materials are sort of manufactured and tested in those standards by the companies that basically develop them. So the titanium that we use here is a medical grade titanium. And also if we were to use stainless steel, what we use is also a medical grade that basically is applied, is gone to rigorous testing. So these are materials that have been tested. They are materials that are used for osteoporotic implants. And these are materials that have shown little biologic activity in the human body. So these are, this is something that the bridge has been crossed, so to speak, and we don't have to worry about. In terms of, it is also used? Student from our business school in doing the market research and the business football. I think we have capability here that we can train students to do the market research and beyond that can add value to your project. Thank you. So I applied two times to them with request to be involved in the project, but in the research as in format of capstone project, but unfortunately there is no response from them. I'm very sorry, you should have come to me. I don't know why they said no. So this is reality. Well, we can talk. Yeah, thank you. So maybe, I don't need the microphone, but can you make any comments about sort of EPIC and maybe next steps? Is there any interest or, I mean EPIC is a, not a group of people per se, do you as a project manager foresee kind of the gradual or quick motion towards EPIC? This part is machined on the exactly same machine tool that we have in our lab, since there is no someone who can...
