My plans for New Year

To finish the year my plans are to finish school with good grades, to go home and be with my family, and see my friends.

And to start the year, I intend to study more, read, exercise, have better grades, but one of my wishes for next year is that my family come live with me, I miss my sisters and talk to my mom, that is something I want very much and I hope will be fulfilled.

Christmas celebrations around the world

Albert Eistein

Albert Einstein was born at Ulm, in Württemberg, Germany, on March 14, 1879. Six weeks later the family moved to Munich, where he later on began his schooling at the Luitpold Gymnasium. Later, they moved to Italy and Albert continued his education at Aarau, Switzerland and in 1896 he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. In 1901, the year he gained his diploma, he acquired Swiss citizenship and, as he was unable to find a teaching post, he accepted a position as technical assistant in the Swiss Patent Office. In 1905 he obtained his doctor's degree.

Einstein always appeared to have a clear view of the problems of physics and the determination to solve them. He had a strategy of his own and was able to visualize the main stages on the way to his goal. He regarded his major achievements as mere stepping-stones for the next advance.

At the start of his scientific work, Einstein realized the inadequacies of Newtonian mechanics and his special theory of relativity stemmed from an attempt to reconcile the laws of mechanics with the laws of the electromagnetic field. He dealt with classical problems of statistical mechanics and problems in which they were merged with quantum theory: this led to an explanation of the Brownian movement of molecules. He investigated the thermal properties of light with a low radiation density and his observations laid the foundation of the photon theory of light.

In his early days in Berlin, Einstein postulated that the correct interpretation of the special theory of relativity must also furnish a theory of gravitation and in 1916 he published his paper on the general theory of relativity. During this time he also contributed to the problems of the theory of radiation and statistical mechanics.

Albert Einstein received honorary doctorate degrees in science, medicine and philosophy from many European and American universities. During the 1920's he lectured in Europe, America and the Far East and he was awarded Fellowships or Memberships of all the leading scientific academies throughout the world. He gained numerous awards in recognition of his work, including the Copley Medal of the Royal Society of London in 1925, and the Franklin Medal of the Franklin Institute in 1935.

Einstein's gifts inevitably resulted in his dwelling much in intellectual solitude and, for relaxation, music played an important part in his life. He married Mileva Maric in 1903 and they had a daughter and two sons; their marriage was dissolved in 1919 and in the same year he married his cousin, Elsa Löwenthal, who died in 1936. He died on April 18, 1955 at Princeton, New Jersey.

Fashion

The fashion indicates in his widest meaning an election or, rather, a regulatory mechanism of elections, realized according to a few criteria of taste.

Those repetitive tendencies are the fashion, be already of clothes, accessories, life styles and ways of behaving, that mark or modify the conduct of a person. The fashion in terms of clothes, defines as those tendencies and genres in mass that the people adopt or die. The fashion refers to the customs that mark some epoch or place specific, especially those related with dressing or adorning. All the persons it has different pleasures of dressing, some of them use more reserved clothes, other extroverts, more elegant, etc., although everything is always going to go per epochs and in every epoch they go away to define different types of fashions as them earlier mentioned.

Ecotourism

The term ecotourism started being used it does next to thirty years, and has been a subject of big debate as for his definition. At present the authentic ecotourism represents a viable option of conservation of the natural and cultural patrimony of the peoples, encouraging at the same time the notion of economic development sustentable.

In 1983, Héctor Ceballos Lascuráin, architect and author, defined to the ecotourism (or ecological tourism) as a form of responsible tourism.

The cloning

What is cloning?

What is the process to cloning ADN?

What is the next step in clonation?

What the scientist think about the human clonation?

What are some aplication of cloning?

What do you think about cloning?

If you could cloning people would you do?

Why?

Cloning can be defined as the process by which identical copies are already developed a body, so asexual. These two features are important:

§ It is part of an animal and developed because cloning responds to an interest in obtaining copies of a specific animal that interests us, and only when adults know their characteristics.

§ On the other hand, it is asexually. Sexual reproduction allows us to get identical copies, as this type of reproduction by its very nature generates diversity.

REPRODUCTIVE CLONING

Reproductive cloning aims at obtaining adult. As we have explained, reproductive cloning has been successfully tested in various mammals. Human reproductive cloning has sparked strong opposition by almost the entire scientific community and institutions in the world. Only a few scientists (Dr. Davos in the U.S. and Dr. Antinori in Italy) were in favor of obtaining adult human beings by cloning, despite harsh criticism from all areas.Just as U.S. sect, led by Rael, were interested in cloning 'the messiah', child of 10 months and cryopreserved died years ago and say they have already raised enough funds to begin cloning a human being.

Ethical issues of cloning

The donation raises interesting expectations, and ethical issues in society and in the scientific community, where there are areas for the use of these techniques and sectors against. In Spain, scientists of the Expert Committee on Bioethics and Cloning, expect for a few more years will not be possible to implement safe techniques of donation, and discard, for the time being any possibility of donation of human beings, limit the use of these techniques to the treatment and cure of genetic diseases, the creation of new drugs, thanks to transgenic animals, and the conduct of xenotransplantation, ie transplantation in humans of organs from animals with a very similar genetic makeup, asthe pig. In this forum we discuss the irresponsibility that would currently applying these methods of donation in humans. It is certain that children could be developed through these techniques presented deformations, such as two heads, two hearts, no hands or feet or an abnormal number of limbs. Themselves "fathers" of Dolly the sheep suggest the chained series of genetic disorders that might arise: genetic codes that identify serious disorders, how, premature aging, cancer and neurological diseases about which there is, today, accurate knowledge.

Ethical problems arise around the issue of accessibility to these techniques by influential people with large ECO3 nomic resources, which could use this scientific instrument as a tool for its own perpetuation. In the case of animals, has raised the possibility of creating populations that although humanity may offer higher quality products would be completely homogeneous and could die very easily to an epidemic.Currently used in transgenic animals, thanks to the techniques of donation, would be an inexhaustible source of organs for human transplantation. On the other hand, although their achievement is fictional, these species could be used to treat many diseases in humans.

Animal cell organelles

Cell Wall: A coating of the cell, composed of carbohydrates and proteins, present mainly in bacteria (prokaryotes).

Plasma membrane: is a thin elastic structure. Its basic structure is a thin film of two lipid molecules thick, which acts as a barrier to the passage of water and soluble substances between extracellular fluid and intracellular fluid. Floating in the lipid bilayer, are protein molecules.

Microtubules: They are part of the cytoskeleton, responsible for intracellular transport.

Golgi apparatus: Membranous organelle consisting of a series of flattened sacs, their functions are: protein secretion, maturation of proteins, glycosylation (sulfation, sulfate groups and carboxylation pastes, sugar paste, carbon groups).

Vacuole: vacuoles segregate waste products of plant cells and remove salts and other solutes whose concentration increases gradually over the life of the cell. Sometimes some solutes crystallize inside the vacuoles, found primarily in plants and have large animals are less frequent and smaller.

Mitochondria (eukaryotes only): Its functions are: cell respiration and ATP production, have two membranes, one internal and one external, has its own genetic material has respiratory enzymes.

Lysosome (eukaryotes only animals): Are spherical sacs containing hydrolytic enzymes (digestive) and digest organic matter. When the cell dies, these bags are broken and released enzymes, digest cellular components.

Endoplasmic reticulum (R.E.): This can be divided into smooth and rough endoplasmic reticulum, and their functions are: to serve irítracelular transport. And the special functions are: smooth endoplasmic reticulum, is involved in lipid synthesis. Rough endoplasmic reticulum, ribosomes have to be responsible for the synthesis of proteins.

Ribosomes: They are not membranous cell components. Aisladpso can be found in the rough endoplasmic reticulum, its role in both cases is the synthesis of proteins.
