Labor plastic 3

Here I present the first process I have chosen, "Extrusion"

This video explains how polymers are made by extrusion. Extrusion is a process in which plastic granules are introduced through a "funnel" and pressed with an auger to a nozzle with different molds. Hence, continuous pieces are obtained. Here are the machines that make the extrusion and the final piece.

This is the first slide that I, as Caesar commanded us to work, well, here the left:

I put this video because when I saw it I was freaking x'D, taught me and I thought people were this geek, I hang it and see what you think lol;)

Do The Symptoms Of Trich Come And Go

Greetings I Kings, this is my blog (obviously). I created it because the teacher has sent me ... -_- to see what it does this. Well I hope that from time to time from people because if I am not going to forget this password. Well, I'm do not know what else to write a greeting.

YEAR YEAR THIRD YEAR PHYSICAL

He biology syllabus of 5th year of the 2nd of Sciences, is structured in four units:

1) genetic continuity

2) The development as a process of differentiation and integration

3) Regulation at the individual level

4) Research Methodology.

This last point will be developed throughout the year, being a major objective the development of a science project. During the first period, students will be making the choice of the theme of work, library research and preliminary work. During the second period, made the experimental or field research, and drafting and completion of work, which has a high percentage within the assessment plan.

It will also update the scientific knowledge on these issues.

The main objective is to achieve a scientific attitude and training int egral, through the development and cultivation of a series of habits, attitudes and skills .

MARKOWNIKOFF RULE

In organic chemistry, Markownikoff Rule made by the Russian chemist Vladimir Vasilevich Markovnikov , said in a chemical reaction of adding a hidrórgeno halide (HX) and a double bond carbon-carbon (C = C) of an alkene asymmetric , the major product halogen is added to carbon double bond having the largest number of substituents opposite and carbon (the one with the least amount substituents) will receive the hydrogen . More specifically, the addition of the nucleophilic Markownikoff first added to the more substituted carbon, and then adding the electrophilic less substituted carbon.

Ex:
CH2 = CH-CH 3 (propene) + HCl (hydrogen chloride) ---> CH3-CHCl-CH3 (2-chloropropane)
CH2 = CH-CH2-CH3 (1-butene) + HBr (hydrogen bromide) ---> CH3-CHBr-CH2-CH3 (2-bromobutane)

ninth-grade biology of basic education, presents the objectives related to areas are specified in the national curriculum, that is, has three large blocks of study. A first part dedicated to the study of the cell, a second segment that includes ideas about heredity and third and last part referring to the study of the evolution of species.
The importance of this program is that it presents a balanced approach to each of the three units that constitute it and allow us to study each unit established school lapse.

All scheduled activities are theoretical and practical orientation.
S and hopes that in addition to proper study of the subject, students learn to acquire study habits science and especially the biological sciences.
