Popocatepetl

The popocatepetl is the most important volcano in México.

The Popocatepetl has a huge maximun height of 5458 meter above sea level.

This volcano was inactive for the last 2 years but in this moment the volcano is very dangerous for the people they live in  around the volcano.



Popocatepetl has been one of the most active volcanoes in México.


Popocatepetl was a brave warrior who loved the maiden Iztaccihuatl.

Mexican invents


1.- A new solution rehidratica: Alejandro Hernandez invented a new solution that can rehydrate rehidatica unidentifiable corpses almost like they just die. This solution could be used with mummified bodies and even, could be one of the greatest inventions of all time, because it could be the fountain of youth ... I saw on the news, and it's really amazing ... in a few hours completely hand engangrenada rehydrate and until it was clear the mark on the ring.

2.- Pill: Luis Ernesto Miramontes was the synthesis of norethindrone, a compound active base of the first synthetic oral contraceptive. Miramontes appeared included in the USA Inventors Hall of Fame Along with men like Newton.



3.-Color TV: Guillermo Gonzalez Camarena invented in 1940 a system for transmitting color TV, Trichromatic System Field Sequential. Later he created a simpler system to create color, bicolor Simplified System. We may also note that television is one of the most used appliances in the world.



4.- Translucent concrete: walls can lift almost transparent, more durable than traditional concrete and has the ability to be cast under water and be 30% lighter than concrete so far known.



 5.- Quality protein maize (QPM Ingés for short): Evangelina Villegas created a double maize quality protein and 10% more degrono. This new product is an instrument in the fight against hunger in the world.



6.-Book on-demand technology: Victor Celorio invented a new printing InstaBook quick call, which publishes a book in 17 seconds, where you can choose the most appropriate design and even the writers without a publisher can print copies.



7.-Mousepad: Armando M. Fernandez resieño for commercial use or mousepad mouse pad in 1979, based on knowledge engineering cost reduction, quality, reliability, characterization and specification of components and systems.


8.-Google and Oracle: The Mexican professor at Stanford University Hector Garcia Molina was who advised and coordinated the doctoral thesis of the students and then Google founders Larry Page and Sergey Brin, and is an advisor to Yahoo!.


 9.- Project GNOME (GNU Network Model Environment): It came in August 1997 as a graphical development environment for operating systems Unix / Linux, composed of free software, creation of the Mexican Miguel de Icaza and Federico Mena.


10.- Piles of control: Due to the complex characteristics of the subsoil of Mexico City with these you can control the movements of the building which is able to continue to the ground during the sinking of the city.


11.-The Rocket Belt (belt flying) a device placed in the back and thanks to the type of motor carrier can fly and has appeared in films like James Bond. Rocket Belt was also the inspiration for the Jet Pack.


12.- System that avoids waste of cold water in the shower that Smart called the Basin.
The operation of this device in the IPN is very simple, as well as their installation. It consists of a valve which is placed before the shower pan. This valve is assembled to a polyethylene tube (PVC), through which the cold water to be stored in a tank of acrylic, once the water is at the desired temperature the valve is closed and the hot water exiting the shower.


13.-  SOLID RAIN TO COMBAT DROUGHT
Jesus The Mexican engineer Sergio Rico developed an irrigation system called "strong rain" that rises almost 20 times the crop yield in arid areas.

14.- Students of the Center for Science and Technology 9 "Juan de Dios Batiz," developed the Triba (garbage disposal), a prototype intelligent garbage that has two compartments: one for organic waste and the other for inorganic, which are independent mechanisms designed to shred organic waste through blades, and reduce the volume of cans, bottles or cardboard, with a plate compactor.

15.- Guillermo González Camarena worked at the radio station of the Secretariat of Public Education (Mexico), while experimenting in his laboratory, until in 1934 produced his own television camera, was 17 years old. Began to improve your TV set, and the latent idea to add color, developed a Trichromatic System Sequential Fields, who won the patent to see that it was possible to adapt the system of white and black. When he was 23 he was granted patent number 40235, for that system, which started from the primary colors.


16.- Tortilla machine
Invented in 1904 by Everardo Rodriguez Arce and Luis Romero, was a head and a rolled roller conveyor chain reached a tortilla comal and produced 16.000 per day. In 1947 Fausto Celorio created the first automatic tortilla machine.


17.- The 'floating automatic shutter' prevents the waste of water in toilets, water tanks and cisterns. It was invented in 1790 by the theologian, historian and journalist José Antonio de Alzate (1737-1799).


18.- Sponge iron

Hylsa development company in 1957 the first efficient process for the direct reduction of iron, through which to obtain the 'iron sponge', a porous material free of impurities, easy to transport and handling.
19.- Indelible ink

 This substance is impregnated in the cells of the skin and stays up to 24 hours. Created by engineer Filiberto Davila Vazquez, Nacionas School of Biological Sciences, IPN, was first used in the vote of 1994 in Mexico.

20.- Propeller Anahuac
Designed in 1916 by engineer and aviator Vilalsana John William (1891-1997), the wooden propeller favored increasing the speed of the aircraft engines. He got such a success that was exported to several countries.

Build an electric motor C. C.



Material to be used.
1 magnet
2 Insurance
1 Battery
1 meter magnet wire
insulating tape
Development

1.- Create a coil of 6 turns with magnet wire. Leaving 5 cm on each side.




2. - Peel each end of the coil.

3. - Put insurance on each end of the stack. Paste them withelectrical tape.

4. - Place the coil into the holes of insurance.


5. - Place the magnet on the stack.




The DC motor is a machine that converts electrical energy into mechanical continuously, causing a rocking motion.








Ammeter:
An ammeter is an instrument used to measure the current that is flowing through an electrical circuit. A microammeter is calibrated in millionths of an ampere and a milliammeter in thousandths of an ampere.

Thin-cutting pliers
Allow you to make very fine cuts and close. The diagonal cutting pliers are very good but you need is to make a court almost glued to a PCB these tweezers are your solution. They have spring for easy operation.


Electric Battery
A battery is a device that converts chemical energy into electricity through a chemical process transition, after which it goes out of business and have to renew their constituents, since these features are altered during the year.

 Electric Alligators
Alligators: cable to generate a short circuit or the circuit where the tips have an alligator for grip.

DIFERENCES PRESENT PERFECT AND PRESENT PERFEC CONTINUOS


DIFERENCES PRESENT PERFECT AND PRESENT PERFEC CONTINUOS

In the Present Perfect: Used to discuss actions that began to happen in the past and are still in this, In the Present Perfect Continuous: It is a time that is used primarily to refer to actions that were initiated in the past and at present are still developing (or just completed).

In the Present Perfect order is: Simple Present of the verb TO HAVE (have, have) + participle of the verb Principal, and the Present Perfect Continuous your order is: auxiliary verb "to be" in the form of "present perfect" (have / has been), plus the gerund (ING finished form) the main verb


In the Present Perfect accompanying adverbs are: Just, Yet, Already, For and Sice, Present Perfect Continuous The accompanying adverbs are: Yet, Always, Never, Ever, Just and Ready


In the Present Perfect is the negative form: the negation "not" between the auxiliary and main verb, the Present Perfect Continuous in the negative is the "present perfect" of the auxiliary verb in its ne
