Wow. Escribiendo esto se me paran los pelos. Este articulo en español es dedicado a un nuevo concepto llamado realidad aumentada. La realidad aumentada consiste en un conjunto de dispositivos que añaden información virtual a la información física ya existente. Esta es la principal diferencia con la realidad virtual, puesto que no sustituye la realidad física, sino que sobreimprime los datos informáticos al mundo real. Los dispositivos de Realidad aumentada normalmente constan de un "headset" y un sistema de display para mostrar al usuario la información virtual que se añade a la real. El "headset" lleva incorporado sistemas de GPS, necesarios para poder localizar con precisión la situación del usuario. También incluye sistemas inerciales y ópticos que son capaces de medir características como son la aceleración, la orientación y el ángulo de inclinación. Los dos principales sistemas de "displays" empleados son la pantalla óptica transparente (Optical See-through Display) y la pantalla de mezcla de imágenes (Video-mixed Display). Tanto uno como el otro usan imágenes virtuales que se muestran al usuario mezcladas con la realidad o bien proyectadas directamente en la pantalla.

Este articulo fue escrito por mis estudiantes de las clases de web development de John Dewey College in Fajardo Puerto Rico. En la escuela superior Dr. Santiago Veve Calzada de Fajardo Puerto Rico, hay un grupo de estudiantes de cuarto año que estan abogando para que la agrupación de música electrónica compuesto por acordes disco, y balada rock con toques de funk, techno, house y synth Daft Punk se presente en Fajardo Puerto Rico.

Daft Punk es un dúo artístico originario de París, Francia; conformado por los músicos Thomas Bangalter y Guy-Manuel de Homem-Christo. El estilo de la agrupación es música electrónica compuesto por acordes disco, y balada rock con toques de funk, techno, house y synth.

 

No importa que tan buena sea su oferta de productos o servicios, eso solo representa la mitad de su negocio. Sus clientes forman la otra mitad. Y ellos esperan un servicio de alta calidad, continuidad en los servicios y sobre todo, que su compañía funcionen como una sola unidad. Nada irrita más a un cliente que tener que repetirle a un representane de servicio lo que le dijo a otro.

Es por eso que el uso de tecnología al manejar su cartera de negocios es esencial. Afortunadamente, independientemente del tamaño de su negocio, hay una solución apropriada para usted. Haga click sobre 'Read more...' aquí abajo para explorar estas opciones.

Linux is no harder to use than Windows, and has many more capabilities. It just takes minutes to get familiar with a distribution like Ubuntu or Fedora, which come with many programs installed. If you need commercial-quality software to work with business documents, Internet/networking, or multimedia and graphics, it's there right out of the box. Want more than that? Linux can do it; there are hundreds of free, high-quality applications you can find and install easily.

You shouldn't assume however, that Linux is a clone of Windows. To know what to expect when stepping into it, we can help you with the basics of switching to Linux. See the below video to learn how to install Linux in three minutes. The Dashway!

The medicines of today

Most medicines in the market are based on simple chemical compounds found in nature, or made in a laboratory out of simple compounds. They are generally known as small molecules.

The exception to these are antibiotics, which are produced by a living organism (like penicillin and erythromicim) or synthetized from substances produced by a living organism (claritromicin is made by performing some changes to the erythromicin molecule). While somewhat bigger, antibiotics are still considered to be in the group of small molecules.

Biotechnology is generally about producing extremely big and complex protein molecules which are only produced by living organisms. This size and complexity makes this molecule very delicate and difficult to process. Sometimes a biotechnology product which is succesfully made in a laboratory, is very challenging to produce in large scale.

The benefits of biotechnology therapy

In the past, the insulin aministered to diabetics was produced by animals. Given its source, the human body did not react to it very well. Thanks to biotechnology it has been possible to have bacteria generate human insulin out of human DNA. This human insulin is perfectly compatible with humans and thus, generally well accepted and effective.

Harnessing the abilities of the bacteria

Bacteria has two types of DNA. The regular one is in the nucleous. However the one that give it superpowers is outside the nucleous and is called Plasmid DNA. This DNA is very simple, in the shape of a ring, and can be transferred from one bacteria to other bacterias (even different type) by simple contact. This DNA stores the genetic code that gives the bacteria its adaptive abilities like antibiotic-resistance.

What the scientifics do is that they split this ring and insert in the middle a chunk of human DNA. Then they insert the ring back in the bacteria, and place the bacteria in liquid full of food for the bacteria to reproduce into a colony. Each of these bacteria will produce, among other things, the protein that the inserted human DNA was programmed to produce. However, the desired protein still inside the celular wall of the bacteria.The tricky part is opening the bacteria to extract its content, and then separating the desired protein from all the other substances inside the bacteria, without damaging it.

Notice that all this process must be performed in a perfectly sterile environment, as it is not possible to use heat or chemicals to kill viruses or other germs without damaging the desired protein. So, after the bacteria is opened, the desired protein is separated using different filter types (some of them are similar to the filters used to process beer). The rest of the process is to formulate the drug to correct concentration and package it. The final product is stored at very low temperatures to protect it from damage.

What else is to this industry?

Well, the process explained above is the core of the concept. However, this fall shorts of understanding the whole process for creating a new biotechnology drug. R&D departments in biotechnology companies dedicate millions of dollars to investigate and explore potential candidates for new drugs. This process is lead by biotechnology scientifics but is also supported by Information Technology analysts dedicated to bioinformatics. These bioinformatics professionals apply Data Mining techniques to the DNA sequences being analyzed to try to find patterns on the genoma associated to specific human conditions.

There is also huge crews of scientifics and supporting personnel dedicated to support phase one, two and three clinical trials. And, there are also other teams with scientifics and engineers dedicated to transform the laboratory process into a industial level factory that will produce exactly the same product developed in the laboratory.

Career opportunities

What I like about Bachelor degree programs in biotechnology like this one http://www.uprm.edu/biotech/ , is that after completing it you have the option to go directly to the labor market to work at a biotechnology manufacturing plant or continue graduate studies in Genetic Engineering, Sciences or Bioinformatics to support the R&D process.
