Francisco's article

Hi everybody. I will write an article about the origin of mitochondria and how their genome has evolved over the time. I'm interested in this topic because I've been working with mitochondria for a long time. Mitochondrion is an organelle that can be found in almost all eukaryotic cells (like mammalian cells). It is called the powerhouse of the cell because it produces most of the energy that cells need to live. However, almost 1 billions years ago, the mitochondrion was a free-living organism that was eaten by another unicellular organism and established a relationship where both parts got some advantages, what we call a symbiosis. I will describe the most important theories that explain the origin of mitochondria, the identity of the ancient organism that participated in the symbiosis, and finally what happened with the genetic information that the mitochondrion’s ancestor possessed.

Jairo´s essay

Hello everyone!! My article it´s going to be about what I am doing for my thesis work, this concerns with analytical chemistry and it is about selective separation of nitro polycyclic aromatic hydrocarbons, this are carcinogenic pollutants that are found on the ambient air, the work is focused on the separations of this compounds from a complex environmental matrix using solid phase extraction for its subsequent analysis with gas chromatography coupled to mass spectrometry, for me it is an interesting topic because is related to what I would like to do ahead as a job or in my master degree.

Brenda's Essay

I'm going to write about "Mexican Women in Art", specially I will develop the period in XIX century when women couldn't be part of the "Academia de San Carlos". I think it's interesting to know the process that female had to live in order to be accepted in a discipline in wich men were the only one who could develop it.
I choose that subjet because this historical period is part of the age known as "Romanticism" and I have been interested in that topic for a long time, so I will present an introduction, a cultural context (in order to understand that age), the subjet develop and finally a conclussion.

Itzel's Essay

A modern Mexican Petrochemical Industry, integrated, profitable and competitived, meeting the internal demand, increasing its participation in national market, reducing imbalance in the comercial scales, exploiting and controlling the comparative advantages of Mexico.

Create others dynamics from oil sector, providing value, generating high quality jobs on a sustained and sustainable way.

For this research paper I'm planning to give a petrochemical industry's diagnosis and propose a series of actions and projects to promote its development.

Efratah's essay

The subject of my research paper is about a type of distillation which generally uses water steam to separate essential oils from solids. The research paper will contain a general background about distillation, the process analysis of this method, the necessary materials, the results of the experiment, the analysis of the results and conclusions.

Isidro´s essay

I'll talk about materials that are used to capture cabon dioxide.

As we now, climate change is one of the most worryng mundial problems. So, materials science has made its aportation during some years to developing new materials which have the capability to capture CO2. Some have more advantages than others in propierties.
In this essay, Global warming is described with its consequences and some solution alternatives. It's explained how materials science have made developments to asume this problem; polymers, ceramics, composites are described with some ways to CO2 is captured.

Also, perspectives and future against CO2 are explained.

It's a very interesting topic for me besides the environmental aspect, for the development and resarch in materials science.

Mily´s Essay

The topic of my reseach paper is "Flow of a Generalized Second Grade Fluid due an oscillating plate". It is about how a specific type of fluid (Second Grade Fluid) moves due the movement of a plate that supports the fuid. Basically, the idea is to give a process analysis about how t o obtain a mathematical expression that describes a physical phenomena (Second Grade Fluid's flow).

Most of the fluids that people know are called Newtonian Fluids, such air and water, they have a well-known behaivor and they have been studied for many years. However, there are other type of fluids, with different features, that have been gaining importance due their applications, such polymers, gels, emulsions, etc. The Second Grade fluid (SGF) could be used to describe the behavior of some polymers (often called viscoelastic fluids); however, that model has some restrictions for describing properly certain flows. In order to extend the applications of SGF model, there are some authors that have developed techniques to "Generalize" the model (improve its reults). One of those techniques is to modify the equation by replacing a derivative of an integer order by a Fractional Derivative (from Fractional Calculus, a specif area of Mathematics).
