From the invisible to the visible world and back.

Nanoparticles and nanotechnology are part of an almost complete new world and to know that it can be aplied to human's health makes it more interesting.
Reading (just before writing) about this topic I found information about a nanoparticle called "solid lipid nanoparticles" (SLN) like it's name said is composed of solid lipids and it's function is to carry.
In pharmaceutical area is used to transportate drugs and protect the active principle in order to arrive complete and be more effective in the organ where is needed.
Thanks to this function the use of drugs have better results because the drug doesn't dissolve in the way (for example, the stomach environment) and it's use have better results.
Besides this, it have more advantages like:
- Decreases the frequency of dosing.
- Reduces drug toxicity.
- Increases drug bioavailability.
All this advantages directly affect patient health and that is the reason this topic caught my attention and because it relates with drugs and pharmacy.

Before to write this post I didn't know so much about nanoparticles, but now I can see a part of their uses, functions, and that this can be applied in a lot of areas. I think that is necessary to develop this technologies for people, science, environment and maybe we can have a better future.

The most enjoyable subject thus far.

From the beginning of this year I knew that at least for four semesters I was gonna have leveling subjects and they are okay, but between these there is one that is called "Chemical laboratory techniques" this subject is so exciting for me because I didn't have chemical laboratories in school so I only learned theoretical chemistry there.

This class is divided in two sections. The first is theoretical and after that we have the practical part. In laboratory we are divided in groups from A to D and each group is formed by about 18 members. We have done different activities and the first classes were about basic things we needed to know like use different types of balance, measure volume with different instruments and more, learn this was important to be ready for more advanced techniques. 

I like this subject because I like to see how the things that we have learned in the theoretical class happen in the lab and simply because is funny, I feel that is similar with cooking that is one of my favourite hobbies. Besides of this reasons I like the environment that forms, the attitude of teachers is ideal because they are willing to answer all your questions and in this type of subjects where your mistake is not just a wrong answer in a paper the disposition of teachers and their assistants is very important.

And this is just my first semester! I hope to discover many subjects that I can enjoy as much as working in laboratory.

Marya Sklodowska.

There are so many scientists throughout history and almost all of them are men but among them is this outstanding physicist and chemist, Marya Sklodowska better known as Marie Curie.

Marie Curie was a polish nationalized french scientist. She was born in November 7, 1867 and passed away in July 4, 1934. She was married with Pierre Curie who was scientist too.
She studied in Sorbonne University, institution where later she became in teacher being the first woman in this position.

Marie Curie

In 1898 along with her husband announced the discovery of two elements: Plonium and Radium thanks to this they won in 1903 the Nobel Prize in Physics and in 1911 she won the Nobel Prize in Chemistry.

I like her because she is one of them most recongnised woman in the science history. There must be others, of course, but I have heard most about her. I like the fact that she excelled in an area commonly dominated for men and that she was the first in some of her achievements, that makes me think she was not interested in what other people could say about her because she was not like the women of her time. Maybe she was the motivation for other women to become interested in science.

About pets, love and friendship...

The truth is, I'm not a pet lover, we have a dog and we have had others and a hamster years ago but that's all.
My dog is called Aldonza, my sister, my mother and I named it and for my sister and I the name was for Pascualina's sister (is a character from a diary) and for my mom was for the character in "El Quijote" (is the real name of Dulcinea).
Aldonza is the daughter of my aunt's dog and I remember that it was with almost all their brothers when we met it, it was so cute with it little dog's face.
We have it since 2006, it is a Cocker Spaniel.
About the hamster we had it during 2005 and his name was Eugenio, rare name for a hamster but is for a story that I'm not gonna tell now and maybe never.
The first pet that I remember is "Fifí" it was a dog, a Cocker too but I don't remember it so much because it was a long time ago .

As you can see this is not a topic that excites me, so I'm done.

A photograph I like

One of the photos that I like was taken by _____ (I will find out because I don't know), and lucky me! the capture date appears in it. It was in 1999 I was three years old by then.

As you can see is a photo of five people. From left to right: a boy (Juan José), a girl (Javiera), a younger girl (Rocío), an old woman (Adriana) and a little girl (as I said in the first post, I'm the youngest sibling). They are my two sisters, my brother and my grandmother.

I like this photo because it makes me feel happy and that's the thing, makes me feel. I think a photo is not complete if it doesn't  makes you feel something and if this feeling is happiness, so much better. Also I like because my grandmother appears, I don't have many memories with her and whit my grandparents in general because all of them died when I was so young, and I'm not sure but is the only picture with one of them that I can remember.

Now I read the previous paragraph it sounds sad, but that's not what I want to transmit! I mean, look this photo! The people in it are happy, maybe their smiles are not so big, but believe me, they are.

And just in case that you ask to where I'm looking at, my mom was in that direction obviously saying "look at the camera" but guess what.

Human evolution timeline.

1.       What's been the role of climate change in the development of humans?

Climate change has given humans the need of adaptation to the different weather, causing the changes needed to survive in their new enviroment.

2.       In your opinion, what is the most significant milestone for the human evolution? Why?

I think that the control of some plants and animals because it allows humans to become sedentary and start civilizations.

Homo habilis.

4.        Who were the first human species to travel to and live in Europe? When?

Homo heidelbergensis. About 700.000 to 200.000 years ago.

5.       Which species survived for the longest time? For how long?

Homo erectus. For more tan nine times as long as our own specie.

About books and films.

When I think in favourites things like food, music, books, places to visit or anything I believe that this must be things that I would like to share with other people, recommend and that I could eat/ read/ watch/go again and again. So whit this thought I have choose these book and film.

I haven't read many books, not because I don't like to read but because I'm a slow reader, I can take almost 6 months and more to finish a book. So between that ones that I've read there is "Papelucho" but ¿WHY? . Is not for the story, is not for the writer and is not because of the characters. Is my favourite for what represents to me, it was the first book that I buy with own money and one of the first that I didn't read for school. I'm gratefull to this book for show me how funny can be reading and the good friend that a book can be.

Unlike books I have seen lots of films so it's difficult to choose one so I just will write about one of the many that I like. 

"Little miss sunshine" is one of my favourites I don't remember when I exactly watched it but its premiere was in 2007 so I suposse that I saw it for the first time in a nearly date to that, but I have seen again since that time. 

This movie is about a family and their trip to carry their little girl to a beauty contest. But is not just the mother and father going with her, also they go with their brother (who has vow of silence), grandfather (the creator of the presentations of his granddaughter) and an auncle (who has just left a psychiatric hospital) all this personalities reunited in a van for a long trip. 

I like it because is not a typical movie of a family trip, every actor and actress make a really good job and because they show how this adventure change their perspectives and fortify their relation.

This is the trailer :)

Also I would like to add that I really enjoy animation films and romantic comedies, I think that are light movies that you can see in any time. Lot of love to Disney and their musical.
