How A Pull-down Projection Screen Works

Project seedlings on bark

A quick update on an experiment carried out on some plants still in early November.
It was some small phalaenopsis, unfortunately the rating, the continuous ripicchiettagi, is a bit 'going to hell so now I will refer to them as generic phalaenopsis. Ripicchiettate were two pots in a sterile environment with a mix of bark, moss, charcoal and fertilizer, sealed and sterilized in a pressure cooker.
The first, pictured above, is still sealed. The phenomenal growth does not appear, but the plants are doing well and the roots, slowly, are expanding. No sign of mold or contamination whatsoever.

The second one, which had been placed in the ventilation system, but in the end was still open in early December. Again, these plants seem not to have any problems, indeed, perhaps the growth is slightly more substantial than the still sealed. The only problem is that the substrate, since the jar inside the "greenhouse" where there are heated and lit the cans with sowing on agar, tends to dry out relatively quickly that you need frequent spraying d ' water. In contrast, the roots, seeking moisture, have taken to develop creep down between moss and bark, as opposed to planting gelatin whose roots are a bit 'where they want, often in the air.
For the moment I'm using simple tap water at room temperature but I think it's better to be short does not saturate with distilled water to the small environment of limestone and salt. In addition we must begin to monitor the humidity of the small home-made emissions so that air does not dry out too much.
In any case we can say that the test to make the transition from acting to the external environment less traumatic to the plants, it would seem to have succeeded. There is always a nuisance that must be sterilized substrate and everything, but I think that will replicate for future transplants.

The meaning of Memorial Day, January 27, 2010








The meaning of Memorial Day



Renzo Gattegna, President of Union of Italian Jewish Communities

Sixty years ago, January 27, 1945, were opened the gates of Auschwitz. The images that appeared in the eyes of Soviet soldiers who liberated the camp, have impressed on our collective memory. At Auschwitz, as in many other concentration camps and extermination camps established by Nazi Germany, were committed crimes of unbelievable cruelty. These crimes were committed not only against the Jewish people and other oppressed peoples and groups, but against all humanity, marking a kind of tipping point in history.

Modern man, with his great wealth of knowledge, in the heart of the continent's most civilized and advanced, had fallen into an abyss. He used his knowledge for criminal purposes, transforming those scientific and technological achievements, of which Europe was then undisputed leader in tools to annihilate and destroy entire populations, first of all the Jews of Europe.

From that trauma Europe and the world woke up very upset. They wondered how it was possible that the Holocaust occurred. And most importantly, what behaviors and actions put in place to prevent that happening again.

awareness of the crimes which the Nazis had spotted was born in 1948 the Universal Declaration of Human Rights, promulgated by the United Nations for the purpose of international recognition of the inalienable rights of all people in every nation.

awareness of what was Auschwitz was one of the key elements for the building, even before the legal identity of the future Europe united.

wrote the philosopher Theodor Adorno that after Auschwitz would be "impossible to write poetry," meaning the idea of \u200b\u200bmaking such radical implications involved to take responsibility in the years of reconstruction and the emergence of a united Europe.

was essential to establish exactly what Europe would not have been. At the root of the ideal setup is the European Union respect for human dignity and the rejection of what had happened, both before and during the war, because of racist ideas and freedom. Auschwitz is the negation of the principles underpinning Europe cohesive, economically, socially and culturally advanced as we know it today.

On January 27, 2010 Memorial Day is celebrated in Italy for the tenth time. Ten years have passed since it was called the Union of Italian Jewish Communities to participate in the implementation of the initiatives promoted by the Italian state institutions and in particular by the Ministry of Education, which would characterize the course of this day. Today, Memorial Day has become a crucial opportunity for schools to form a great many young people through teaching and research.

Since then, the Italian Jewry was repeatedly questioned on how to propose a reflection that not be emptied of its deepest meanings, reduced to mere celebration. Beyond the right and necessary items on the Shoah and Memory, we believe that we must seek to perpetuate the true meaning of this day.

Many have been in recent years, studies, articles, discussions, publications of scholars and intellectuals who have tried to constantly define and redefine the meaning of Remembrance.

fact, there is an issue of the relationship between History and Memory. The Holocaust is now consigned to history books, along with other events of the past. A few witnesses were telling us about their experiences. It could be considered a memory crystallized in the books as an important event but far away in time, to be studied like any other chapter in a textbook, with the risk of making away the meaning and the real reason why Memorial Day was established by law.

Humanity demands that what happened does not happen again, anywhere and at any time. E 'of paramount importance that new and future generations to do just that in teaching more lively and participatory as possible, stimulating debate, questions, "because" essential for the understanding of these tragic events.

wrote the philosopher Hannah Arendt, that evil has neither depth nor demonic dimension. May hold the whole world and destroy it, precisely because it spreads like a fungus on its surface. It 's a challenge to thought, because thought he wants to go down, try to get to the roots of things, and when that is interested in evil is frustrated, because there is nothing. This is the banality. Only the good has depth and can be radical.

The philosopher who, perhaps more deeply studied the aberrations of Nazism, coining the now famous phrase "the banality of evil", referring to one of the main perpetrators of the Holocaust, provides a definition of neutrality and gloomy sloth who does not think , who does not reflect, to those who have own ideas, who does not value and feedback to their actions and their consequences. Arendt links the "right" to direct thought, a vital source of understanding of the world.

encouraging us in a lively discussion guys, maybe we will make the best possible service to this day that, to be lived in the most authentic, it needs a thought is not static, not notional.

be provided to the new generation of tools, including empirical, to think about what humanity has been able to do because it never happens again.

This is perhaps the truest sense of the Holocaust Memorial Day, and is a valuable asset for all.
