CARACAS, Venezuela –The Brazilian President Luiz Inácio Lula da Silva met the Venezuelan President Hugo Chavez on February 14, 2005 in Caracas, Venezuela. Brazil and Venezuela signed agreements of cooperation on many areas. According to the Brazilian government this was a strategical encounteur. This meeting is the first of three meetings that President Lula will have with South American Presidents in three days. The scheduled meetings are with the presidents of: Venezuela (February, 14), Guiana (February, 15) and Suriname (February, 16).

President Lula was accompanied by the following comitiva: the Minister of Development, Industry, and External Trade Luiz Fernando Furlan, the Minister of Finance Antônio Palocci, the Minister of Foreign Relations Celso Amorim, the Minister of Health Humberto Costa, the Minister of Mines and Energy Dilma Roussef, the Minister of Tourism Walfrido Mares Guia, the President of Petrobras José Eduardo Dutra, the President of National Economic and Social Development Bank (BNDES) Guido Mantega, the President of Eletrobrás Silas Rondeau Cavalcante Silva and the Special Secretary for Aquaculture and Fisheries José Fritsch. In addition a delegation of executives representing enterprises from Brazil accompanied the President.

The Brazilian Ministry of External Relations told the trip aims the construction of a strategical alliance and commercial integration between both countries. The Brazilian Presidential Advisor Marco Aurélio Garcia said:”With this gesture, Brazil will consolidate one of its major political goals, which is the constitution of a South American community of nations”. He added: “These agreements with Venezuela are strategical. We want this agreement as a model for other agreements in the region.”

According to President Lula the integration of the Latin America is the priority number one of his government. Days before the arrival in Venezuela and commenting about the trip Lula said: “We’re going to do the same thing in Colombia and in other countries in which integration is no longer a campaign speech but part of the way we deal with real things, day to day”.

The integration of the Latin America is the politics repeatedly proposed by Lula during the meetings of the Foro de São Paulo. According to him and the others members of the Foro there must be a integration among all the left parties and governments of Latin America. The union aims to be an alternative and opposing force to the politics and influence of the richest countries, mainly the United States. Among the organizations which are usually participants of the Foro de São Paulo are: Communist Party of Cuba, Colombian Communist Party, Communist Party of Bolivia, Communist Party of Brazil, Workers’ Party, Paraguayan Communist Party, Peruvian Communist Party, Socialist Party of Peru, National Liberation Army, Revolutionary Armed Forces of Colombia, Farabundo Martí National Liberation Front, Guatemalan National Revolutionary Unity, Tupamaros.

On December 4, 2001 during the 10th edition of the Foro de São Paulo in Havana Lula said:”A shoal of small fish may mean the finishing of the hungry in our countries, in out continent. We should not think as the History ended on our journey by the Earth. Even it happens just once, or with one gesture, let’s effectively contribute to the improve the life of millions of human beings who live socially excluded by this neoliberal model.”[1]

In Venezuela, once again, he brought out the integration wish: “This is the biggest dream I am carrying, that we can negotiate collectively, not like one country, but like a set of countries so we can do that our people may have the chance to conquer the full citizenship.”

The combined efforts of agents from the Afghan Commandos and Coalition forces have led to the discovery and destruction of two-and-a-half tonnes of marijuana in an abandoned school in the southern Afghan province of Kandahar on Friday.

Kandah?r province or Qandahar (??????,{??????) is one of the largest of the thirty-four provinces of Afghanistan. It is located in southern Afghanistan, between Helamand, Oruzgan and Zabul provinces. Its capital is the city of Kandah?r, also spelled Qandah?r, (?????? or ??????), the second largest city in Afghanistan, with a population of 450,300 (2006 estimate). Kandahar City is located on the Arghandab River. The province has a population of nearly 890,000, with more than 300,000 living in its capital city. The main inhabitants of Kandahar province are the Pashtun people.

An improvised explosive device and an unexploded mortar round, both 100-meters away from the school, also were destroyed.Foot patrol by the combined forces yielded tips which led to the drug discovery. A Commando also discovered a large room filled with marijuana seeds. The marijuana was placed in two-foot-tall (0.6-meter) stacks that filled multiple 12ft-by-12ft rooms. Rust on the furniture suggests the Afghan schoolhouse may not have been used as such for a long period of time. No students or faculty were around at the time of the drug bust.

U.S. Forces Afghanistan spokesperson, Col. Jerry O’Hara said that “using drugs to fund insurgent activity is bad enough; using a school as a drug warehouse is an attack on the future of all Afghanistan.”

Xinhua has reported that “according to a recent U.N. report, Afghanistan produces over 90 percent of the world’s opium as Taliban militants will benefit nearly 500 million U.S. dollars from opium trade in 2008.”

Meanwhile, coalition troops have killed four militants in Zabul Province. They also detained five suspects on Saturday. Adm. Mike Mullen, chair of the Joint Chiefs of Staff, said that “the United States would send between 20,000 and 30,000 more forces to Afghanistan by summer.” “Those forces will primarily move into the country’s south, where the insurgency is the most entrenched,” he added.

22-year-old Dutch native Joran van der Sloot was charged yesterday with the murder of Peruvian Stephany Flores. Stephany Tatiana Flores Ramírez, the 21-year-old daughter of a former Peruvian presidential candidate, was found beaten to death in Van der Sloot’s hotel room on May 30, 2010. The two appeared to have met only hours before while playing poker at a nearby casino. Flores was found four days later by an employee of the Hotel Tac in the Miraflores District of Lima. Van der Sloot had previously requested that no hotel staff enter his room.

As Flores was being buried by her family, Van der Sloot was arrested in Chile after trying to escape from Peru. Van der Sloot, who lives in Aruba, was extradited to Peru on June 4. At first, he told police there that, while he had met Flores, he had not killed her, but late last week, he confessed to murdering her. Van der Sloot claimed that he only killed Flores after he found her looking through personal files on his computer.

Joran van der Sloot is the only suspect in the 2005 disappearance of Alabama teenager Natalee Holloway during her school trip on Aruba. Holloway was last seen on May 30, 2005, exactly five years before Flores’ death. Van der Sloot, however, was never charged in connection with the disappearance.

Van der Sloot will be held in solitary confinement for the next few months “for his own safety.”

Western Australian Master Builders Association (MBA) yesterday demanded the Carpenter Government call an emergency cabinet meeting to avoid a “state of emergency” over the energy crisis gripping WA. A MBA spokesperson said that hundreds of workers have already been stood down, many without pay, and that the cost of building material is soaring.

The Minister for Energy, Fran Logan has admitted that the gas shortage caused by Tuesday’s fire is damaging the economy as mining, manufacturing and construction industries wind back operations. Western Australia’s two major brick producing companies have shut operations and Wesbeam’s $A100 million Neerabup pine production facility has been closed, their 130 employees have been stood down.

Wesbeam chief executive James Malone said, “It’s an industrial tsunami in my view. It’s a little ripple that has very quickly had a huge multiplying effect on the whole community”.

Michael McLean, Master Building Association director said “It’s a worst-nightmare scenario, and not one we could have imagined in our wildest dreams,” building supplies are expected to start running out by the middle of next week.

Premier Carpenter has announced a meeting of ministers and industry representatives to take place on Sunday to discuss solutions to the growing crisis. Tim Wall, managing director of Apache Corporation has said Apache is conducting a worldwide search for the parts need to repair the pipeline.

Major mining companies and Apache partners BHP Billiton and Rio Tinto have already reported they are suffering with the loss of gas supply; the Chamber of Minerals and Energy has talked down the effect saying that they don’t expect the crisis to take the heat off the booming mining industry.

Opposition leader Troy Buswell has describe the performance of Fran Logan as “absolutely dismal” noting that Mr Logan had experienced a similar incident in January this year, when a fire at Woodsides Karratha operations had a similar effect.

Today, United States Senator Ted Kennedy underwent surgery for a brain tumor at Duke University Medical Center. Kennedy, 76, was diagnosed with malignant glioma, a common but dangerous form of cancer, after suffering a seizure on May 17.

Kennedy has met repeatedly with friend and medical advisor Dr. Lawrence C. Horowitz to plan a course of treatment. The first, of the major phases of that treatment has now been completed, and it is expected that chemotherapy and radiotherapy will follow.

“I am pleased to report that Senator Kennedy’s surgery was successful and accomplished our goals,” said Dr. Allan Friedman, the chief of neurosurgery at Duke, who performed the surgery. “After a brief recuperation, he will begin targeted radiation at Massachusetts General Hospital and chemotherapy treatment,” Friedman added.

In talks with the press, the senator has focused on his future beyond surgery. In a prepared statement issued by his office, Kennedy stated, “after completing treatment, I look forward to returning to the United States Senate and to doing everything I can to help elect Barack Obama as our next president.”

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10^-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube ¹/₆₄ inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.

People rallied in 300 locations across Australia today to protest the Federal Government’s proposed changes to industrial relations laws, WorkChoices. According to police, around 150,000 people congregated in Melbourne, from where speeches were broadcast throughout the country. In Sydney, thirty thousand gathered in Belmore Park and Martin Place to watch the broadcast before marching to Chifley Square.

Sharan Burrow, President of the Australian Council of Trade Unions (ACTU), said that under the changes many working conditions would be under threat, including “penalty rates, public holidays, overtime pay, control over rostered hours, shift penalties, even 4 weeks annual leave.” The government has claimed, despite various expert assesment to the contrary, and opposition from major Australian religious and charity organisations and some concern from its own backbench, that the IR changes will improve the economy and ultimately benefit workers, and dismissed the protests as having “little effect”.
