Lubuntu is an official release of the Ubuntu project that is “less resources and energy efficiency,” using the LXDE desktop manager

Lubuntu is an official release of the Ubuntu project that is “less resources and energy efficiency,” using the LXDE desktop manager.

The name is a combination Lubuntu LXDE and Ubuntu.

The manager LXDE uses Openbox window manager and try to be an operating system that requires few resources RAM, CPU and other components, specially designed for laptops with limited resources electronic cigarettes like netbooks, mobile devices and old computers. With this ideal development scheme that has, is presented as a competition Xubuntu.

LXDE desktop for Ubuntu will be available as an optional package since version 8.10.

In February 2009 Mark Shuttleworth was invited to join LXDE as a joint project with the Ubuntu community, in order to lead a new operating system called Ubuntu from Lubuntu.2 6

In March 2009, the project was created in Launchpad Lubuntu by Mario Behling, including an early version of the logo. In addition, the project was announced in the Container Store official Ubuntu includes the list of applications, packages and components including the system operativo.3 7

Students Kepler exoplanet Cordoba and 22b

I have all week in my hometown, Córdoba, and as usual when I come here I have little free time. As you see, is so small that it might take more than two weeks without putting a new story here. So here’s a quickie.

On Wednesday, December 7, I had to give talks in schools in Córdoba Astronomy. Earlier I was in college Trinitarians (where, incidentally, will be a preschool) and 1 pm beginning my talk at the Salesians , which is the place where I studied from 1 st GBS to COU, and that, by tradition, have given talks on astronomy every year without interruption since he was in 1 st BUP. For these lectures I used a new presentation, titled A tour of the Cosmos: Planets, stars and galaxies in an evolving universe . Although for this presentation I created new slides with recent astronomical images and videos of course also contained many old slides, including some classic use for more than a decade. Anyway, as I have the bad habit of putting much more of what I know I have time to tell me why I bring the kids questions to go with more depth some issue or another. Honestly, I love having this contact with the students, who make many interesting and intelligent questions that show curiosity and interest they have on the topics of astronomy. Personally, I was still surprised to be able to payday loan endure, with good behavior, a guy talking about stars and galaxies for nearly two hours. Okay, try to make it entertaining and I keep asking questions to think a little, but one thing does not remove the other.

As expected, both schools received many questions about the controversial definition of a planet and the many exoplanets are now encountering. In particular, sure most of you have heard or seen that early in the week the news became public that the planet Kepler 22b , with has a size of about 2.4 Earth diameters (a super-Earth ) but located at 587 years light of us, toward the constellation Cygnus lies within the zone of habitability of the star Kepler 22. This star is slightly smaller and cooler than the Sun, but stable. This would indicate that about this exoplanet rock could have liquid water, and if so Kepler 22b could even be a habitable world and life.

The sizes of the planets with each other to scale, although the size custom t shirts of the planet Kepler 22b is not precisely known, but is estimated to be about twice Unlock iPhone that of Earth. Credit: NASA / Ames / JPL-Caltech .

However, as it says astronomer Daniel Marín in his blog, Kepler 22b is not the first confirmed exoplanet in the habitable zone of its star , in effect, had already confirmed that the exoplanet Gliese 581 d and HD 85512 b are Also in this privileged area around its star. Of course, Kepler 22b it is the first exoplanet discovered with these characteristics for the mission Kepler , whose main objective is precisely to discover planets around other stars habitable. In fact, Kepler 22b is one of 54 potentially habitable exoplanets announced in February 2011 by the Kepler mission scientists, so hopefully in the coming months we have new confirmations of exoplanets. Possibly, these new findings also will cause a media frenzy similar to what has led to the confirmation of Kepler Criminal Defense Attorney Chicago exoplanet 22b as in the habitable zone of its star, so be careful with what you say and comparisons. To help understand this, Daniel Marin also blogged the story FAQ about the new planet Kepler 22b , which I highly recommend taking into account now and for future confirmations.

Total Lunar Eclipse

The Moon will be completely wrapped in red light
Awakening before sunrise can be difficult, especially during the weekend. On Saturday, December 10, possibly taste you have. During the early morning in western North America, you can see a total lunar eclipse.

The event will start around 4:45 am (Pacific Standard Time) when the big red shadow of the Earth falls on the lunar disk. At about 6:05 am (Pacific Standard Time), the Moon will be completely wrapped in red light. This event (the last total lunar eclipse until 2014) will be visible from the Pacific side of North America across the Pacific Ocean to Asia and Eastern Europe.

This photograph, taken by Jens Hackman, Weikersheim, Germany, during a total lunar eclipse that took place in March 2007, shows the periphery of turquoise and red engagement ring nucleus of the Earth’s shadow across the face of the moon.
For those who inhabit the western United States, the eclipse will be most intense just before local sunrise. Look west to see the red moon sinking on the horizon as the sun rises behind him. It’s a strange way to start the day.

The moon will not only be beautifully red, but will corporate clothing also be extended by the Moon Illusion. For reasons that astronomers or psychologists still do not fully understand, the Moon at low altitude appears larger than normal when seen through the trees, buildings and other objects found at the bottom. In fact, a cna certification low moon is not bigger than any other moon (the cameras prove), engagement rings but the human brain insists otherwise. For observers located in the Western United States, therefore, the eclipse will be large.

But atmospheric scientist Richard Keen, University of Colorado, you might also know. For years he has studied lunar eclipses as a means to monitor conditions at the top of the Earth’s atmosphere and has become an expert in forecasting these eventos.Podría seem puzzling that the moon becomes red as it enters the shadow of the Earth, is not it supposed that the shadows are dark? In this case, the delicate layer of dusty air surrounding our planet reddens and redirects the sunlight, thus filling the darkness that lies behind Earth with a bright reddish color like a sunset Sun The exact shade (anyone going from bright orange to blood red is possible) depends on the unpredictable state of the atmosphere at the time in which the eclipse occurs. As he loved to tell Jack Horkheimer (1938-2010), the Space Transit Planetarium Miami (Miami Space Transit Planetarium, in English): “Only the shadow knows.”

“Probably this eclipse is bright orange, or copper-colored, with a possible touch of turquoise on the edges,” he predicts.

The Earth’s stratosphere is the key: “During a lunar eclipse, most of the light illuminating the moon passes through the stratosphere, where it is reddened by scattering,” says Keen. “If the stratosphere is full of dust that comes from volcanic eruptions, the eclipse will be dark, a clean stratosphere, on the other hand, produces a brighter eclipse. At this time, the stratosphere is almost clean, with little input of dust from volcanoes Recent “.

That explains the brightness of the eclipse, but what about the Bankruptcy “touch of turquoise”?

“The light that passes through the upper stratosphere penetrates the ozone layer, which absorbs red light and, in fact, makes the beam of light that passes by it becomes more blue. This can be seen as a soft blue margin around the red center of the Earth’s shadow. ”

Look for electronic cigarette review the turquoise near the beginning of eclipse, when the edge of the Earth’s shadow sweep the lunar terrain, advises Richard Keen.

A great eclipse of the moon, bright red and turquoise with a touch of soft, will be held Saturday December 10. Wake up and enjoy the show.

 

The cell cultures: their future

The cell cultures are the future, they are one of the stars of biotechnology through them can opterse any plant product, so natural barta
PART ONE

We started growing plants about 10,000 years ago and since then has not pay day loans stopped evolving the way of culture, media and technology advance, increasing their production, evidently in the early years, progress was slow, as the knowledge of man were practically nil, or at least advancing very slowly, we could say that non-existent.

As in all fields of human knowledge, with increasing technology, new advances and increased practical knowledge, that, increases the technical and scientific progress exponentially, this always the case in all branches of human knowledge, knowledge are different techniques to grow and progress.

Clearly, in recent years, scientific advances and knowledge stored, have fired the progress of agriculture, have increased in a manner so obvious that they have been taken from the routine of traditional culture.

In its early days, the men began to select most productive plants in short, our ancestors began to make very early genetic manipulation, a manipulation that was to select the cultivars more productive, higher quality and disease resistance.

At the same time also selected the most productive land and had to spend a few thousand years, to be able to select some tasks more convenient, genetic selection began, before the selection of land and labor practices.

At present, this is much faster, not many years ago, maybe thirty, maybe some more, we learned to do without the earth began to develop hydroponics, plant them dispensed soil, which produced several benefits, first, get rid of soil parasites, including fungi and insects, so the bacteria.

Everything was relatively easy, just did not need to make a nutrient solution, with the sixteen essential nutrients and their proper proportions, of course, conductivity and pH suitable for denver martial arts the roots, free and floating in the fluid, it must also contain the proper mixture of gases such as oxygen, carbon dioxide and other gases in the soil and are essential for normal root growth.

We had already dispensed with the soil and its drawbacks, some time before, had dispensed with the weather incidents such as temperature, humidity and even the gaseous contents of the atmosphere surrounding the plants, as the proportions of carbon dioxide and contents of moisture.

At the beginning of life, had only cells, unicellular organisms
It’s time to control another crucial factor in the cycle of plants, light, sun, our only light, but also managed to replace, even fool the plant by altering its cycles, lengthening the day or night annotating, creating springs or simulating autumn, which we must complete with temperature control.

Now the time has come to dispense with the plant without its leaves, its roots and trunks and therefore, apart from the air conditions, we do not have limitations, we have no land, no water, no weather or light cycle; only have cells, back to the beginning of life.

At the beginning of life, had only cells, unicellular organisms that produced everything they needed.

Only culture cells, we will introduce in boats, floating in a known way and ideal, absent from all parasites and controlled all the factors, light, temperature, nutrients, gases, hormones, and therefore cycles, with continuous production and unlimited.

To cultivate cells and control all these parameters, we need a proper technique and a suitable means, that’s obvious, but certainly not using this technique we just get rid of the auto insurance quotes parasites of the soil and air, we look for something else; that’s true, we seek continuous production, industrial production, unrestricted and unfettered, as can pests, diseases and weather.

In cell cultures, we got rid of most of the enemies who have attacked our crops from the early days of homo sapiens, since the insects, fungi, parasites and viruses, dismantled, destroyed our crops, the only was to survive.

Now in our time, things have changed, our interests have changed in many of our crops, we have ceased to interest the ripe, and we are only interested flavors, juices, extracts and other products we get from them, which we call secondary metabolites.

Among secondary metabolites, we can distinguish some really Denver Divorce Attorney interesting for us, or therapeutic interest in the economic Relevant Life Policy interest, some of them, as some anti-cancer products or for the manufacture of perfumes or antibiotics, but also creates numerous insecticides and fungicides, some of them can even be used as biological insecticides or fungicides.

Many times, investment in cell culture, are even smaller, cheaper, than investing in traditional culture, we must bear in mind that investment in biotechnology is certainly the future, essentially in a holding cell cultures is the laboratory, which will have the means to isolate, reproduce and grow the cells we are interested, this will explain it in full in the next chapter, now I will explain the scientific basis, all this project is based on a plant, any plant capable of producing a given active substance (drug, insecticide, fungicide, perfume etc.) only produces this substance, in a small number of cells and only in very specific moments of your cycle, so that in these cells and these cycles focus wedding ring our crops.

The cell cultures (Part Two)

Are some of the techniques of cell cultures fermentedores describing the selection of strains and in nitrogen consevación Lequan

Cell cultures: The future

PART TWO

 

To start a cell culture, we must Cell Phone Accessories choose a healthy silver, Nutrisystem Coupon Code disinfect it and select the cells that produce the metabolite (product) that we want, then isolate a group of these cells, which initiate cultures in Petri dishes.

We will ensure, to bring into cultivation, enough plates, tailor made suits ten at least, so that we can then reject all contaminated and select the strains showing healthy, clean and sufficient.

Using techniques of subculture, and again sow a new petri dishes, and go discarding contaminated by bacteria or fungi, which is normal to happen, using living plant material and although we will make the seed sown under sterile hood washing after using the proper techniques, the explant to use for planting.

Of these, we subcultures, over and over again, and we will select the most vigorous and healthy, to obtain pure cultures and with great capacity for replication and growth.

For example, if we get essence of rosemary, the explant, we will get a strong plant smell, mesocarp of a healthy leaf in a healthy plant.

Later, we will begin to give them the right conditions of production, nutritional level of the medium, temperature, lighting period and free auto insurance quotes hormonal balance, in this way, we can begin to control metabolite production capacity of each strain or culture.

After choosing the most productive strains, either as explant or “street” or “cell suspension”, this will depend on the type of cell, a plant chosen and bring to the fermenter and other liquid nitrogen container.

The fermenter should suit the type of crop and conditions maintain the basic server monitoring parameters: temperature, medium, nutrients, pH, conductivity, hormonal balance, automated and constant which will lead to the first cells to reproduce and grow exponentially, then when reaching the stationary phase, began to produce the metabolite continuously.

In the liquid nitrogen container, we can keep almost indefinitely, a remnant life insurance quotes online of strains, prepared to replace the producers, to renew the crops remain productive over time, almost indefinitely, while maintaining the productive capacities and quality of the metabolites obtained.

The fermenter should suit the type of crop
There are different ways to extract the metabolite (product), depending on the physicochemical characteristics of this, in the case of an oil can be decanted, if it is a gas or a liquid easily sublimable, simply raise the temperature the medium to its sublimation temperature and get to the top of the fermenter, in the case of soluble, a electronic cigarette separation of the medium, causing its precipitation, in short, depending on the nature of the metabolite, study and find the way remove it.

It is very important to keep strains in reserve to allow for a continuous renewal thereof, to remain productive and is best kept frozen at -198 ° C, ie in liquid nitrogen, as this is the only way that guarantees proper conservation, almost indefinitely.

Fermenters should be chosen with care, since the amount of medium, the gaseous contents and other factors are limiting and dependent on many factors including the type of cell, which also imposes limits on the size of the fermenters .

As for the limitations imposed on us to get products, metabolites that we are interested in a plant, virtually no limits, you can get anything, any metabolite, web hosting any product obtained from a plant, can be obtained by this system obviously have to fine-tune the methods, you should outline details, but can be obtained oils, perfumes, flavors and so on.

In fact, today, you get oils, perfumes, flavors, which are sold around the world are available carbohydrates, proteins and fats are also obtained hormones, anabolic steroids and all without the dangers of outdoors, without parasites or viruses; is available from the tomato flavor to nicotine or hormone you to imagine, drugs such as taxol and all derived from plants, lower cost and without losing a apex of quality.

The fermenters in which products are obtained, they can have very different sizes, depending on the needs or the capacity of each company, also of market demand, existing in industrial operations, five-liter fermentors, fifty, one thousand, fifty thousand to five hundred thousand, only depends on the market, the actions which each product, but also the needs of the crop limiting factors exist, especially when the metabolites that can be obtained, are toxic, this limits the size Medifast coupon code of the medium, also when impair cell growth, but this is controlled by different systems, from continuous extraction to complete change of culture medium.

The methods of extraction are very important, as the size of these means limited to the fermenter and its systems, are also involved in production capacity.

We should note that in no way disturbs the quality of the laser hair removal resulting products, metabolites, are even more pure than those obtained from traditional and certainly much more in demand by industry, medicine or any type of customer; also lower their cost of production.

Production by cell cultures allows us to leave it less well technologically companies, traditional products, producing apples, melons, beets, potatoes, etc.. In companies or countries that can afford a cheaper labor, but European farmers can not compete with that, we must go to produce otherwise.

Scientists at the University of Texas discovered liquid water in the basement of a moon of Jupiter

Scientists at the University of Texas at Austin (USA) have discovered water in the crust of Europa, a moon of Jupiter, a finding that has been published in Nature

Scientists at the University of Texas at Austin (USA) have discovered water in the crust of Europa, a moon of Jupiter, a finding that has been published in ‘Nature’ and that, according to experts, would be a step ” significant “for the search for life beyond Earth. Thus, he has found what appears to be a body of liquid water with a volume similar to the Great Lakes of North America, enclosed within the icy crust of the moon Europa . According to lead author, Britney Schmidt, a professor at the Institute of Geophysics of the University of Texas, the water could represent a STD Testing potential habitat for life How to lose weight and there may be many more lakes in the shallow regions of the crust of Europa.
In addition, the newly discovered lake is covered by floating ice shelves appear to be collapsing with each other, providing a mechanism for the transfer of nutrients and energy between the surface and the vast ocean under the ice.

“One of the views of the scientific community has been that if the ice is thick, this would prevent the surface to communicate with the underlying ocean,” says Schmidt, while warning that is now before the evidence that, although the ice is thick, it allows the flow of energy, which could make Europe and its ocean “most livable places.”

A puzzling ice.

In addition, the scientists focused on the pictures, taken by the Galileo spacecraft, two circular areas on the surface of Europe, called ‘chaos’. Based on similar processes that occur on Earth, where ice shelves and glaciers on volcanoes in, the researchers developed a four-step model to analyze the terrain in Europe. Upon analysis, there were several contradictory observations: some seemed to indicate that the Discount Judaica products ice is thick and others are thin.

“I read the document and immediately thought, yes, that is, it makes sense,” said Robert Pappalardo, a research scientist in the Department of Planetary Sciences at NASA , which indicates that it is the “one model fits all range of observations. ”

In addition, scientists have good reason to believe that their model is correct, scrabble word finder based on observations of Europe’s Galileo spacecraft. However, because the lakes are located car shipping several kilometers below the surface, the only real confirmation of its presence will come after a future mission spacecraft denver personal injury lawyer designed to explore this layer of ice that mission has been ranked as the second priority, according to the latest ‘Planetary Science Decadal Survey ‘, and is currently being studied by NASA .

“This new information on Europe would not have been possible without the observations collected during the last 20 years about the layers of Earth’s ice,” said Don Blankenship, a co-author and research scientist at the Institute of Geophysics, University of Texas.

Jupiter is the fifth planet of locksmiths the Solar System. It is part of the so-called gaseous outer planets. Named after the Roman god Jupiter (Zeus in Greek mythology).

It is the planet that offers higher brightness along the year depending on its phase. It is also after the Sun, the largest celestial body in the solar system with a mass almost two and half times that of the other planets combined (with dui lawyer chicago a mass 318 times that of Earth and 3 times higher than that of Saturn ).

Jupiter is a gaseous body mass, composed mainly of hydrogen and helium, lacking a defined inner surface. Among the details highlighted weathering the Great Red Spot, a huge anticyclone located in the tropical latitudes of the southern hemisphere, the banded cloud structure bright and dark areas, and the dynamics determined by intense global atmospheric zonal winds alternating in latitude and speed up to 140 m / s (504 km / h).

Jupiter is the most hcg diet plan massive planet in the solar system: equivalent to about 2, 48 times the sum of the masses of all the other planets combined. However, it is the most massive planet known: more than a hundred extrasolar planets have been discovered have masses similar to or higher than that of Jupiter. Jupiter also has the fastest rotation speed of the planets of the Solar System tour in less than 10 hours on its axis. This speed is deduced from measurements of the planet’s magnetic field. The atmosphere is divided into regions with strong zonal winds with rotation periods ranging from 9h 50m 30s, in the equatorial zone, 9h 55m 40s for the rest of the planet.

The planet is known for a great training weather, the Great Red Spot readily visible to amateur astronomers because of its large size, larger than the Earth. Its atmosphere is permanently covered by clouds that can plot the atmospheric dynamics and show a high degree of turbulence.
