Oral presentation

Transcription:

Hello everybody, I’m Víctor Rosillo and I’m going to talk about my research project. The topic is anemia.

I choose this topic because is on the scientific area, that I am and I would be the next year. Because I would like to study an engineer.
Moerover, I choose this topic and no other cientific topic because on my famili there are some people who suffer the disease. On specific Iron deficiency anemia. And I thought that it could be a good idea learnt some thing about it to help their of the best way as possible.

My objectives are: the study of anemia, the study of the iron deficiency anemia, and the determination of iron on a medicine against the illnes on the laboratory by two techniques.

The theory part of my project is about the anemia in general.
Anemia is a blood’s disiease that decrease in number of red blood cells. On this situation the hemoglobin, one of the most importants components of the red blood cells, can’t do it his main function which consist on: carry oxygen from the lungs to the tissues.


The main cause of anemia may be classified as impaired red blood cell (RBC) production, increased RBC destruction and the blood loss.

To treat the disease, first you’ll have to know what kind of anemia is, the cause and the seriousness of it. Then the doctors will chose the best treatment.
The objective of the treatment is increase the quantity of oxygen that the blood can carry.

To fulfill the objective, first the patient will change his diet. If the change don’t found he’ll have to use some medicines. On an extreme situation the surgery can be the last solution.

When I finished the theory part, I did the practical part. To realize them, first I use the spectrophotometry. Consist on the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.

First, I prepared solutions of different concentration. Of 2,4, 6, 8 and 9 milligram per liter. Then I determinate the absorbance of the solution and with them I made the king straight. Finally I determinate the absorbance of the problem solution and I fix the quantity of iron on a medicine against anemia.

The result it was very good. We determinate 102,6 in front of the 105 milligrams determinate by the prospect of the medicine. This small difference can be causes by a red layer that cover the pill, or because of the bad and imprecise quality of the laboratory’s material.




Afterwards, I used the redox tritation. are based on a redox reaction between an oxidizing agent and a reducing agent( the iron)

The result of iron on a pill that I determinate was 96,9 milligrams. I suppose that this error could be cause another time by a bad material.

Finalized the research project, I can say that I fulfill my objectives. And I didn’t suffer any setback. Moreover, I think that the experience is very positive because of now I can say what is anemia, and I have learnt to use two different technical of determination, but overcoat I learn to use the laboratory’s elements.

I think that the research Project helped me a lot to consolidate some aspects of chemistry that I did in class, and to learned a lot of new things.

Finally, I can say that the project give me a small idea about the laboratory‘s chemist, which can be very useful on my imminent future if I decide to do an chemistry engineer the next year.


Opinion:

This is my second oral presentation of the year. Because of that I hope that everybody could saw an improvement. I used a lot of resources: A PowerPoint, and a lot of pictures which helps to me to do a better presentation.
As you can see on the video, I was very nervous like the other time, but I think that I was looked all the time at the audience and I didn’t read my notes because I wanted to hold the attention on my topic and not on me.

I can say that the structure of the exposition it was the correct because was very important to me on my research project. The ideas were in order and correctly links. I say that some of the audience was interested on my topic, anemia. I believe that I used a rich and scientific vocabulary because it was very necessary to talk about the disease.

In spite of that, I think that the pronunciation was very bad because of I was very nervous, and because If I am realist I don’t know talk well in English. I would like to improve my pronunciation but I think that is very difficult for me If I won’t go to England or similar.

Finally, I have to put my own mark. At difference of the other presentation that I think that I deserved a low mark, on this time I believe that I get a 7,5. I will improve the next time a littler more.
