When the trance came, it was Slytherin that the Ink pulled from his mind...
...lies and deception -- when the truth was too dangerous; ruthless decisions -- painfully made but rightly decided ; fearful glances from those around -- when complacency might have been fatal; strength that came when only despair was possible ; and beyond all, the might of a dark power that thrived in the deepest shadows of the night.
This time his thoughts shaped a darker image -- an emerald snake full of deadly grace and patient plans, hypnotic in its calculating coldness, and brutal in its will to survive -- a symbol of endurance, and a banner for Dark things.
To this standard alone would the broken and downtrodden come -- those who were too damaged to trust in hope anymore -- and for whom bright joy was a strange language they no longer understood . But Harry understood -- and with that part of himself that had always been Slytherin, he could still touch them, and they would see themselves in him, and allow his protection.
In darkness, he could find the lost and despairing -- and in darkness he would gather them home.
I Love That sleepy face of yours ... Amor de mis amores

Equalize Pitty
Sometimes if I get distracted If I do not watch over an instant I transfer myself over to you 've seen that can not be so Me soon come loose
What is that smell from you to me a perfect flow
As you talk and kiss me At the same time I see Its colors in your eye, so close Me rocking slowly How you swoon me when
easy rolling rhythm seems to have been tested
And I think I really like you Well the way you are I will equalize you a frequency that only we know I turned you in this song, Before you write to me
I love this guy his sleep And the sound of his voice What keeps telling me things so crazy And that almost kills me to laugh When tries to convince me that I only stayed here Because we're both equal It seems that you had My manual Because you decipher my dreams Because you know what I like And because when you hold me The world spins slowly
And time is just my And no one records the scene From suddenly turns into a movie All in slow motion
And I think I really like you Well the way you are I will equalize you a frequency that only people I know
transformed in this song, Before you write to me (2x)
Equalize Pitty
If I sometimes get distracted If I'm not careful for a second I transport my self closer to you I just can't be left on my own That smell soon comes to me That comes from you to me In a perfect flux

I love that sleepy face of yours And the tone of your voice That tells me really crazy things And nearly makes me laugh to death When you try to convince me That I only stayed here Because we're both one of a kind
It's like you've already had My manual of instructions Because you decipher my dreams Because you know what I like And because when you hold me The world spins slowly And time goes by so fast And nobody captures the scene Suddenly it turns into a Whole slow motion movie And I think I really like you Just the way you are I'm going to equalize you In a frequency only know by us I turned you into this song So I can record you on me
But it's the best I can do My gift is my song And this one’s for you

Sat on the roof And I kicked off the moss Well some of these verses Well they, they got me quite cross
But the sun’s been kind When I wrote this song It’s for people like you that Keep it turned on
So excuse me forgetting But these things I do You see I’ve forgotten if They’re green or they’re blue
Anyway the thing is What I really mean Yours are the sweetest eyes I’ve ever seen

Do not let it go away This feeling has got to stay Don't let it go away This feeling has got to stay And I can't believe I've had this chance now Don't let it go away
New, you're so new You, you're new And I never had this taste in the past New, you're so new
My normal hesitation is gone And I really gravitate to your will Are you here to fetch me out? 'Cause I've never had this taste in my mouth
Oh you're not old And you're not familiar Recently discovered and I'm learning about you
New, you're so new You, you're new
And you're consuming me violently And your reverence shamelessly tempting me Who sent this maniac? 'Cause I never had this taste in the past
Oh you're different, you're different from the former Like a fresh battery, I'm energized by you
Don't let it go away This feeling has got to stay Don't let it go away This feeling has got to stay And I can't believe I've had this chance now Don't let it go away
Why am I so curious? This territory is dangerous I'll probably end up at the start I'll be back in line with my broken heart New, you're so new You, you're new And I never had this taste in the past
Don't let it go away This feeling has got to stay Don't let it go away This feeling has got to stay And I can't believe I've had this chance now Don't let it go away

The art of losing isn't hard to master; so many things seem filled with the intent to be lost that their loss is no disaster.
Lose something every day. Accept the fluster of lost door keys, the hour badly spent. The art of losing isn't hard to master.
Then practice losing farther, losing faster: places, and names, and where it was you meant to travel. None of these will bring disaster.
I lost my mother's watch. And look! my last, or next-to-last, of three loved houses went. The art of losing isn't hard to master.
I lost two cities, lovely ones. And, vaster, some realms I owned, two rivers, a continent. I miss them, but it wasn't a disaster.
---Even losing you (the joking voice, a gesture I love) I shan't have lied. It's evident the art of losing's not too hard to master though it may look like (Write it!) like disaster.
-- Elizabeth Bishop
I carry your heart
I carry your heart with me (I carry it in my heart) I am never without it (anywhere I go you go, my dear; and whatever is done by only me is your doing, my darling). I fear not fate (for you are my fate, my sweet) I want no world (for beautiful you are my world, my true) and it's you are whatever a moon has always meant and whatever a sun will always sing is you.
Here is the deepest secret nobody knows (here is the root of the root and the bud of the bud and the sky of the sky of a tree called life; which grows higher than soul can hope or mind can hide). And this is the wonder that's keeping the stars apart.
Peace is a gift from God, but an arduous duty to be conquered every day by dint of superhuman grace and love. Torment is all the more cruel because it is great love that gives, understanding that love and expectation, hope and commitment that we take an experience. The basis of true peace is not to circumvent any of the consequences of our experience, not to worry because it is neither frightened because it fails. Forgiveness does not mean forgetting, but remember without pain. Forgiveness means taking away the emotional charge to the memory, to understand and assimilate an experience and that, if we hurt less.
What is repeated is not repaired, and repaired, we have the intensity of our experiences, because the passion to stimulate reflection. Servicing is required to avoid repeating the error because understanding the past is essential to building the future truth. Fix to avoid duplication, and that sometimes involves radical changes that these pains will become someone else. To remove the emotional pain is impossible, as it is to remove it to love. Pain and love are emotions, so you can not remove the essence of what it is.
sure there is more behind every black day. There is something else behind every dead heart.
Usually, the man believes that health, happiness and freedom are gifts from heaven, or at least elements of nature required, however, deserve it costs a lot of pain and conquer. Peace is a gift from God, but an arduous duty to be conquered every day by dint of superhuman grace and love. In these times, man knows many things but does not know himself, so you'll forget that without a minimum of pain can not build the great states of consciousness, personal and collective life that always renewed pain.
Because if not internalized, if you meditate, is impoverished. Within the rhythm that we printed daily life is more than necessary to try two things: limit the binary clock and spirit that will inevitably kill spiritualization human force. It is important to rescue the restraint and patience.
Suppose that our life is difficult, we suffer pain. A torment is all the more cruel because it is great love that gives, understanding that love as the expectation, hope and commitment with which we assume a experience. However, a man really good escape misfortune. Is it bad that happens to us prevents us from being just, magnanimous, temperate, prudent, modest and free?. Suppose we hurt others, how can it prevent our mind be pure, wise, sober and righteous?.
often forgotten that pain teaches us all, we are all equal and we are all redeemed. is the only element that is right at us with compassion. And similarly, it ignores the hidden vein of joy, at least in line, which carries with it the toughest setback, the most terrible adversity. And it is that existence is a total mystery, kept in check by the habit and custom. However, the basis of true peace is not to circumvent any of the consequences of our experience, not to worry because you are, or frightened because it fails.
Life is not a novel that's life. And life is like: front side of glory, back pain. The reverse forget this is what leads to personal and social catastrophes. Human beings know that welfare should be shared among everyone. But we must also share the pain, look where it exists, drink the drink that each person we touch, and be able to find in their feces, the source of peace.
To find it, we need to locate and assimilate the memories that shake, content or hurt the heart, a fact that not infrequently requires forgiveness. Forgiveness does not mean forgetting, but remember without pain. Forgive means taking away the emotional charge to the memory, to understand and assimilate an experience and that, if we hurt less.
Another way to face life's Resignation ... Resign ... Reframing ... The assimilation and adaptation imply humility, receive life and experience without prejudice to resignify experiences, because everything has resumed to grow, that is, accept to respond, first of all with peace and free will.
Die to the past to locate in this, that's the only life. The existence requires converting the fault liability. What is repeated is not repaired, and repaired, we have the intensity of our experiences, because the passion to stimulate reflection.
First, pain is the necessary antecedent of the action. The added value of learning, before the action, far exceeds the cost of unpleasant surprise. repair is necessary to avoid repeating the error because understanding the past is essential to building the future truth.
And if you do not want to be wise, nor fair, and pure, or mild? What if you just do not want to live this pain away? And when someone just wants to be human, their miseries and vulnerabilities? Why accept a pain that transforms you when you do not want to be different from what you are? Because you say truth that action is needed, not to repeat repair, and that sometimes involves radical changes that these pains will become someone else. to remove the emotional pain is impossible, as it is to remove the love. Pain and love are emotions, so you can not remove the essence of what it is. Here in God's world, we are not saints and ascetics, we are human we cried and laughed, which hurt us and try to forget the pain by changing an interior that is not ours. There are times when peace becomes the utopia we all want in and that the same pain that life gives to "redeem? are those who deny and obscure. However, sure there is something more behind every black day. There is something else behind every dead heart. find if difficult task, but surely there.
Valley Artists Exhibition "Fish Town" in New Literary Cafe Parque Bustamante raulí
Next Tuesday 5 August 2009, at 18:30. my new exhibition opens "Fish Town" in the newly opened Literary Cafe Parque Bustamante, Baquedano subway steps.
The works in the exhibition "Fish City" are sculptures of welded iron and stainless steel, which hung from the balcony that faces the pool of water. Also be exposed several unpublished prints.
I am very happy because it is the first art exhibition of the Café, which has already been integrated into the cultural circuit of our community must Providence, with more than 800 visits a day, excellent collection of books, free wi fi and cafeteria.
The exhibition will be on display until 12 September, and all works are for sale.
is a dinosaur "type rex rusty iron, welded to the bow for me, can by can, cut and perforated. It measures 4.10 meters
. high, 2 meters wide and 3.40 meters long.
was created by me in 2001, during a course of Bachelor of Arts, Catholic University.
He lived in the courtyard of my house until February 2004, when we changed, and given that not fit in the new site was donated and moved to Interactive Museum MIM Mirador .
Throughout the year 2004 I worked in the workshop of the MIM, using machinery spaces and they provided me. Reinforce its structure and apply products to protect from excessive rust.
On May 4, 2005 "B raulí" was officially opened, being set in gardens of MIM, permanently.
In this lab we will remember as much volume as the use of the scale. We will also check the decomposition of hydrogen peroxide (H 2 or 2), catalyzed by potassium iodide (KI). The decomposition of hydrogen peroxide is: 2H 2 O 2 (aq) -> 2H 2 O (l) + O 2 (g)
potassium iodide (KI) is a catalyst because it only increases the reaction rate is not spent as a reagent. However, a small part if it reacts, becoming iodine. The presence of iodine is shown by the brown color in parts of the product. The iodine stain. The reaction is performed in a graduated cylinder rather high, since the product formed vertically upwards and out quickly. That and its texture is called "toothpaste." As hydrogen peroxide is a very strong oxidizer must protect hands with gloves. In addition, the reaction is very fast, it is advisable to wear safety goggles. MATERIAL
PROCEDURE 1. Put the plastic on the table to prevent staining. 2. Weighing in the watch glass 15 g of potassium iodide (KI) and put them in the absorber. 3. Add the minimum amount of water needed to dissolve. Shake until dissolved completely. 4. Put on rubber gloves and measures 40 ml of 30% hydrogen peroxide in 100 ml graduated cylinder and pour into the cylinder of 250 ml. 5. Add about 20 ml of liquid detergent and removed (by swirling) until the hydrogen peroxide and detergent mix. 6. If you like, add a little coloring in some parts of the mouth of the specimen so that the leaves striped toothpaste. 7. Add the potassium iodide solution to the tube and hand away quickly. Stand back a little of the specimen. 8. You can bring a stick fire to the mouth of the tube and see what happens.
Today I will speak of hydrogen and a practice we do from this item. Hydrogen is a colorless, odorless tasteless. Like most gaseous elements, hydrogen is diatomic molecules containing two atoms (H 2 ), but dissociates into free atoms at high temperatures. There are three known isotopes of hydrogen. The nucleus of each ordinary hydrogen atom contains a single proton. Deuterium (about 0.02% in natural hydrogen) contains one proton and one neutron in the nucleus, with atomic mass of two. Tritium (a radioactive isotope unstable) contains one proton and two neutrons in the nucleus and has an atomic mass of tres.A ordinary temperatures hydrogen is very reactive.
not react with oxygen at low temperatures, but it does so violently if the temperature rises above 700 º C or any solid catalyst such as palladium or platinum finely divided, yielding water as a product of this reaction. When hydrogen is mixed with air or oxygen is turned on, the mixture explodes to form H2O, as the reaction
H 2 + O 2 -> H 2 O
This property is used in the practical process to identify the gas produced as hydrogen. Acts as a reducing agent for metal oxides such as copper oxide, removing the oxygen and leaving the metal free state. Hydrogen can combine with oxygen from oxides of other elements and reducing this character is used in metallurgy for metals with a high degree of purity such as tungsten filaments for electric lamps. Reacts with many non-metals. Combines with nitrogen in the presence of a catalyst to form ammonia NH3, with sulfur to form hydrogen sulfide H2S and chlorine to form hydrogen chloride, HCl. Also combined with more active metals like sodium, lithium and calcium, to form hydrides (NaH, LiH and CaH2). It also reacts with unsaturated organic compounds to form the corresponding saturated compounds.
There are many methods for obtaining hydrogen. Industrially it is usually obtained from water by electrolysis, or recovering from natural gas. In the laboratory, to obtain small amounts of hydrogen, zinc is usually treated with dilute hydrochloric acid, a process in which zinc chloride is formed and hydrogen follows: 2HCl + Zn
-> ZnCl 2 + H 2
hydrogen Globe
MATERIAL
beaker, filter flask, plug, globe, funnel, fine wire (1 meter), lighter, rod 1 meter sail. Products: Hydrochloric acid (HCl), granules of zinc or zinc powder, soap, glycerin.
PROCEDURE Enter settling tube a plug holes. Before, Rub with glycerin to keep from sticking. Enter plug in the vacuum flask. Full half the funnel with hydrochloric acid. Put the shot zinc in the filter flask. Place a balloon on the tube of the filter flask, tying with a rubber to prevent leakage. If the pressure is not strong enough, will not swell. Under the supervision of your teacher, key opens the funnel with care, since it is dangerous. When the balloon is inflated enough, tie it with thread. Notes that rises upwards. Ata the candle to the stick. Turn it on. Stand in an open and under the supervision of your teacher, about the candle to the globe and see what happens e.
Chromatography is a separation technique based on the different mobility which have different solutes contained in the same solvent. The means by which they move is called stationary phase and the solvent through which solutes move is called the mobile phase. This solvent can be a gas or liquid, although we only deal with the mobile phase liquid chromatography and solid stationary phase. Practice we do on this occasion is:
Chromatography of spinach extract
MATERIAL
2 beakers, a square piece of cardboard used as a cover, filter paper , dropper, mortar. Products: Alcohol, sand, spinach.
PROCEDURE
Chop the spinach in a mortar with a little sand. Add alcohol and stir until you see the color of spinach has absorbed the alcohol let it stand. Go the solution to a beaker. Prepare a filter paper strip 4 cm wide and 10 cm in length. Fill the dropper with the solution of the dye of spinach. Make a small spot about 4 cm from one end of the dropper on the strip of paper. Wait to dry the stain and repeat the process 3 or 4 times so that the stain is more concentrated.
Insert it into a beaker with alcohol 've previously covered with cardboard (1cm high alcohol) without stain touch the eluent.
After some time distinguish you a dark green line corresponds to chlorophyll b, the other light green of chlorophyll a, one more yellow xanthophyll orange and yellow carotenoids.
Magnesium is the least active of the alkali metals. It is ductile, malleable and, although white, is easily coated with a layer of white oxide (MgO) which gives the gray metal that we normally see. It is widely used by lightweight alloys for aircraft. Burns easily react with oxygen and nitrogen from the air, why is widely used in fireworks because it creates in the combustion a very intense white light of short wavelength.
Mg + O 2 -> MgO 3 Mg + N 2 -> Mg 3 N 2
We will conduct two practices relating to magnesium
Cut 2 cm of magnesium ribbon. Please scratch this off with a spatula and examines the color and brightness that appears. Turn it on with the help of crucible tongs.
reaction of magnesium with hydrochloric acid-2 MATERIAL
halfway into a crystallizer. Full exhaust tube with water almost completely, and add 5 ml of concentrated hydrochloric acid (pour making sliding down the wall of the tube gases, fume cupboard and under the supervision of your teacher).
Finish filling the tube with water so that the meniscus beyond the edge of the tube, but not dripping. cover the tube with the bottle, turn it over and insert it in the crystallizer so that it is as follows: weighs 2 cm of magnesium ribbon and insert it quickly into the gas tube. expected to complete the reaction and record the volume of gas evolved. Back cap the gas pipe and remove it from the water. With the tube still blocked on a call and he removes the tube. See what happens.
The next practice we will take measurements of volume with the probe and the pipette while we make a fun experience.
start from a known volume of tap water and do a trick "magic." Consist of changing the water glass and appear to be transformed into wine. To move the contents to a third vessel, appear to be transformed into C oca-Cola. In the first conversion, which occurs is that potassium permanganate, which is deep violet, dissolved in water. In the second conversion, hydrogen peroxide reduces the permanganate ion (violet color) to MnO 2 , yellowish solid that remains in suspension. In addition, oxygen is evolved gas. This oxygen, which is responsible for the bubbles, is essential in combustion and that is why if we bring a small flame to an atmosphere rich in this gas, it will burn more vivacity. The chemical reaction that takes place is:
2 KMnO 4 + 2 H 2 O 2 -> 2 MnO 2 + 2 KOH + 2 H 2 O + 2 O 2 -
MATERIAL
Three beakers, graduated cylinder, 100 ml, 2 ml pipette, pear security filter paper. Products: Potassium permanganate (KMnO 4 ), concentrated hydrogen peroxide (H 2 O 2). PROCEDURE
Make a small stick about 10 cm long wrapped with filter paper. Leave it ready. Leave the first glass clean. Put a few pieces of solid potassium permanganate in the second beaker. Measured 4 ml of hydrogen peroxide with a pipette and pour into the third beaker. Measure 100 ml of water with the specimen and Transfer it to the first beaker.
water passes first to the second vessel. Observe and record what happens. Repeat the process content from the second to the third glass. Observe and record what happens. Turns cane and Bring it to the beaker near the bubbles. You must hurry and do this before the end of the reaction and hence bubbles are exhausted Observe and record what happens.
