Egypt’s top courts suspend work in protest at Mursi

Egypt’s Cassation Court and the country’s most important appeals court said on Wednesday they would suspend their work pending a ruling on the constitutionality of President Mohamed Mursi’s decree granting him immunity from judicial review. (from yahoo.com)

“The Cassation Court will suspend its work starting today,” the court’s vice chairman, Abdel Nasser Abu al-Wafa, said after a meeting of the court’s top officials.

Khaled Abdellah, a judge in the Cairo and Giza Appeals Court, said after a similar meeting that his court would also suspend its work “except in cases related to corruption and personal laws”.

There were chaotic scenes in both meetings as judges, divided over the Constitutional Court’s latest statement, argued over what to do.

A spokesman for the Supreme Constitutional Court, which declared the Islamist-led parliament void earlier this year, said on Wednesday that it felt under attack by the president.

“We did not find the Constitutional Court’s statement of simply condemning President Mursi’s decree enough,” Abu al-Wafa told Reuters after the meeting. “We are deciding on the next step after suspending work.”

Egypt court sentences 8 to death over prophet film

An Egyptian court convicted in absentia Wednesday seven Egyptian Coptic Christians and a Florida-based American pastor, sentencing them to death on charges linked to an anti-Islam film that had sparked riots in parts of the Muslim world. (from yahoo.com)

The case was seen as largely symbolic because the defendants, most of whom live in the United States, are all outside Egypt and are thus unlikely to ever face the sentence. The charges were brought in September during a wave of public outrage in Egypt over the amateur film, which was produced by an Egyptian-American Copt. The low-budget “Innocence of Muslims,” parts of which were made available online, portrays the Prophet Muhammad as a fraud, womanizer and buffoon.

Egypt’s official news agency said the court found the defendants guilty of harming national unity, insulting and publicly attacking Islam and spreading false information — charges that carry the death sentence. Maximum sentences are common in cases tried in absentia in Egypt. Capital punishment decisions are reviewed by the country’s chief religious authority, who must approve or reject the sentence. A final verdict is scheduled on Jan. 29.

The man behind the film, Mark Basseley Youssef, was among those convicted. He was sentenced in a California court earlier this month to one year in federal prison for probation violations in an unrelated matter. Youssef, 55, admitted that he had used several false names in violation of his probation order and obtained a driver’s license under a false name. He was on probation for a bank fraud case. Multiple calls to Youssef’s attorney in Southern California, Steve Seiden, were not returned Wednesday.

Florida-based Terry Jones, another of those sentenced, is the pastor of Dove World Outreach, a church of less than 50 members in Gainesville, Fla., not far from the University of Florida. He has said he was contacted by the filmmaker to promote the film, as well as Morris Sadek, a conservative Coptic Christian in the U.S. who posted the video clips on his website. In a telephone interview Wednesday, Jones said the ruling “shows the true face of Islam” — one that he views as intolerant of dissent and opposed to basic freedoms of speech and religion. “We can speak out here in America,” Jones said. “That freedom means that we criticize government leadership, religion even at times. Islam is not a religion that tolerates any type of criticism.”

In a statement sent to The Associated Press Wednesday, Sadek, who fled Egypt 10 years ago and is now a Coptic activist living in Chantilly, Virginia., denied any role in the creation, production or financing of the film. He said the verdict “shows the world that the Muslim Brotherhood regime wants to shut up all the Coptic activists, so no one can demand Copts’ rights in Egypt.” Coptic Christians make up most of Egypt’s Christian minority, around 10 percent of the country’s 83 million. They complain of state discrimination. Violent clashes break out occasionally over land disputes, worshipping rights and love affairs between Muslims and Christians.

The connection to the film of the other five sentenced by the court was not immediately clear. They include two who work with Sadek at a radical Coptic group in the U.S. that has called for an independent Coptic state, a priest who hosts TV programs from the U.S. and a lawyer living in Canada who has previously sued the Egyptian state over riots in 2000 that left 21 Christians dead. In a phone interview, one of the men sentenced who works with Sadek, Fikry Zaklama, said he had nothing to do with the film and hadn’t even seen it. “When I went to look at it (on the Internet), they told me it had been taken down,” said Zaklama, 65, a Coptic activist and retired physician who practiced in Jersey City, N.J. “I’m not interested. I’m not a clergyman. I’m a political guy.”

Nader Fawzy, a 53-year old jewelry store manager (sic! 6/66) and president of an international Coptic rights organization from Toronto, Canada, said he planned to file a lawsuit against the Egyptian government in Canada for what he said was a wrongful prosecution. He said he’s terrified of being kidnapped and spirited to Egypt. Fawzy, who came to Canada in 2002 from Sweden and lost his Egyptian citizenship in 1992, denied any involvement in the film. He said the Egyptian government has long been out to get him because of his Coptic Christian activism. “Of course, I’m worried about this death penalty,” Fawzy said, adding that the verdict has limited his ability to travel freely. “Who will give me guarantees that the Egyptian government will not try to kidnap me, to take me to Egypt?”

The other person is a woman who converted to Christianity and is a staunch critic of Islam. The official news agency report said that during the trial, the court reviewed a video of some defendants calling for an independent Coptic state in Egypt, and another of Jones burning the Quran, Islam’s holy book. The prosecutor asked for the maximum sentence, accusing those charged of seeking to divide Egypt and incite sedition. All the defendants, except Jones, hold Egyptian nationality, the agency added. Some Christians and human rights groups worry that prosecutions for insulting religion, which existed to a degree under the secular-leaning regime of deposed President Hosni Mubarak, will increase with the ascent of Islamists to power in Egypt.

M23 Rebels Enter Eastern Congo City

The rebel group M23 has entered the city of Goma in eastern Democratic Republic of Congo, continuing their advance against government and United Nations troops. The rebels say they have taken the airport and witnesses say they are near the city center. (from voanews.com)

After days of fighting, M23 rebels have succeeded in their drive against the Congolese army and U.N. peacekeepers and advanced into the capital of North Kivu province.

While the exact situation in Goma is fluid, all accounts say that the rebels are gaining ground.

M23 making advances

Some residents and several journalists confirm M23’s claim to have taken the airport, on the eastern side of the town. Journalists say the rebels also have captured one of the two main border crossings from Goma to Rwanda, also on the eastern side of town.

Congo analyst Thierry Vircoulon of the International Crisis Group said the situation is taking a dire turn for the worse.

“My feeling is that the city is about to fall and we’ll know that during the course of the day, that’s for sure,” said Vircoulon. “And there have been exchanges of fire between Rwanda and the DRC, which means we may not be very far from an open conflict between the two countries.”

UN launches aerial attack on rebels in east Congo

U.N. attack helicopters targeted M23 rebels in eastern Congo on Saturday after fighting resumed following a monthslong lull in violence, a local official said. Two army officers and 151 rebels were killed in a battle beginning Thursday that the U.N. called the worst clash between the M23 group and the military since July. Attack helicopters for the U.N. mission in Congo, known as MONUSCO, had been on standby. (from yahoo.com)

‘‘MONUSCO helicopters this morning bombarded the M23 positions in the city of Kibumba,’’ said North Kivu governor Julien Paluku. He said the Congolese army had earlier retreated from Kibumba, which is 30 kilometers (19 miles) north of Goma, after thousands of Rwandans, who he says were backing the rebels, attacked early Saturday.

‘‘The fighting was very violent between the Congolese military and the M23 rebels backed by the Rwandan army,’’ he said. ‘‘Rwandan forces bombarded our positions in Kibumba since early this morning and an estimated 3,500 crossed the border to attack us.’’

Reports by United Nations experts have accused Rwanda and Uganda of supporting the rebels. Both countries strongly deny any involvement and Uganda said if the charges continue it will pull its peacekeeping troops out of Somalia, where they are playing an important role in pushing out the Islamist extremist rebels.

At U.N. headquarters in New York, peacekeeping chief Herve Ladsous said the rebels were very well-equipped, including with night vision equipment, which allowed them to attack at 4 a.m. However, he said that UN officials did not know who was supplying the M23. ‘‘At this stage we are not in a position to confirm whether or not Rwanda was directly involved in those attacks.’’

Earlier on Saturday, Secretary-General Ban Ki-Moon had called Rwandan President Paul Kagame ‘‘to request that he use his influence on the M23 to help calm the situation and restrain M23 from continuing their attack,’’ Ladsous said.

The U.N. Security Council called for an immediate stop to the violence following a two-hour, closed-door emergency meeting. The council said it would add sanctions against M23 rebels and demanded that rebels immediately stop their advance toward the provincial capital of Goma.

‘‘We must stop the M23’’ because Goma’s fall ‘‘would, inevitably, turn into a humanitarian crisis,’’ said France’s UN Ambassador, Gerard Araud. He added that U.N. officials would decide in the coming days which M23 leaders to target for additional sanctions.

Bosco Ntaganda, who also is thought to be leading the M23 rebellion, is under an International Criminal Court arrest warrant for similar war crimes.

The council also warned that any attempts to ‘‘undermine’’ the U.N. forces’ mandate, which includes protecting civilians, ‘‘will not be tolerated.’’

The IAEA spreads the science for harnessing the world´s aquifers.

We know water is essential for life. Less known is that there may be enough freshwater for everyone — if the world´s resources are well understood and responsibly managed.

Water is key to achieving socio-economic development. It is also a crucial element of poverty reduction efforts. In the Millennium Declaration, UN Member States resolved “to halve by the year 2015 the proportion of people who are unable to reach, or to afford, safe drinking water” and “to stop the unsustainable exploitation of water resources, by developing water management strategies at the regional, national and local levels, which promote both equitable access and adequate supplies.” (from iaea.org Bulletin 47/1)

Nearly half of all freshwater used for drinking and irrigation worldwide is groundwater, linking the sustainability of groundwater resources to sustainable human development.

The steady increase in global demand for freshwater, coupled with rapid industrial and agricultural development, is threatening the availability and quality of fresh water supplies. Today, a large part of the world population particularly in regions of water scarcity suffers from the lack of sufficient water supply. Mahatma Gandhi put it aptly more than 60 years ago when he said “there is enough water for human need, but not enough for human greed.” According to the report of the UN Secretary General to the 2002 World Summit on Sustainable Development in Johannesburg, the global water crisis also is a crisis of governance.

In Africa, for instance, inadequate access to water and sanitation is considered both a cause and consequence of poverty. Although there are abundant water resourceson the continent — about 17 large rivers and 160 lakes greater than 27 km2 — most of these resources are located in the humid and sub-humid region around the equator. The surface runoff in Africa, on average, is much lower than average precipitation as a result of high evaporation and evapo-transpiration. This results in endemic drought in parts of the continent.

That is why for Africa groundwater — the underground ponds and lakes of aquifer systems — is a critical resource. It provides nearly two-thirds of all drinking water on the continent, and an even greater proportion to the peoples of northern Africa. Similarly, water resources in South America approximate 3 million km3 and only the equivalent of one-tenth of the total amount of water contributed by precipitation is used every year. The major problems these countries face are sustainable groundwater use and prevention of contamination of the available resources.

Groundwater Lifelines

Globally, groundwater represents about 90% of available freshwater resources, excluding the resources locked in polar ice. Nearly half of all freshwater used for drinking and irrigation worldwide is groundwater, linking the sustainability of groundwater resources to sustainable human development.

About 20% of irrigation worldwide, producing 40% of the food supply, is dependent upon groundwater. It is estimated that nearly 10% of global food production may be dependent upon irrigation water extracted from fossil or non-renewable aquifers. According to the Food and Agriculture Organization (FAO), the use of groundwater for irrigation over the last several decades probably has delayed the next food crisis.

The Science of Isotope Hydrology

Despite the importance of groundwater for many societies, there is a lack of corresponding public concern about its protection, perhaps because the extent and availability of groundwater are not easily measured. The impact of the increasing degree of temporal and special climatic variability on the water resources also is an important consideration. Groundwater, to some extent, provides an opportunity to mitigate the impacts of climate change.

To develop sustainable management and policy frameworks, it is necessary to have sound hydrological information on the quality and quantity of water resources. Making such information available requires a substantial amount of time and financial resources, and generally cannot be achieved on the short time scale at which societal demands for water supply have to be met.

Nuclear and isotope methodologies provide powerful tools for hydrologists to rapidly assess and manage water resources at a vastly lower cost. Stable and radioactive environmental isotopes have now been used for more than four decades to study hydrological systems and have proved particularly useful for understanding groundwater systems.

Applications of isotopes in hydrology are based on the general concept of “tracing”, in which either intentionally introduced isotopes or naturally occurring (environmental) isotopes are employed. Environmental isotopes (either radioactive or stable) have the distinct advantage over injected (artificial) tracers in that they facilitate the study of various hydrological processes on a much larger temporal and spatial scale through their natural distribution in a hydrological system. Thus, environmental isotope methodologies are unique in regional studies of water resources to obtain time and space integrated characteristics of groundwater systems. The use of artificial tracers generally is effective for site-specific, local applications.

The most frequently used environmental isotopes include those of the water molecule, hydrogen (namely deuterium, and tritium) and oxygen (oxygen-18 as well as carbon-13 and carbon-14) occurring in water as constituents of dissolved inorganic and organic carbon compounds. Deuterium, carbon-13 and oxygen-18 are stable isotopes of the respective elements whereas tritium and carbon-14 are radioactive isotopes.

Among the most important areas where isotopes are useful in groundwater applications include aquifer recharge and discharge processes, flow and interconnections between aquifers, and the sources, fate and transport of pollutants. In particular, under arid and semi-arid climatic conditions, isotope techniques constitute virtually the only approach for identification and quantification of groundwater recharge.

Pollution of shallow aquifers and of deeper aquifers due to the over-exploitation of shallow aquifers, by anthropogenic contaminants is one of the central problems in the management of water resources. Environmental isotopes can be used to trace the pathways and predict the spatial distribution and temporal changes in pollution patterns for assessing pollution migration scenarios and planning for aquifer remediation.

Global Maps of the World´s Aquifers

The IAEA´s Water Resources Programme aims to develop isotope techniques for water resources management and assist scientists to use these techniques correctly. A substantial part of the programme focuses on groundwater. Estimates of the world´s groundwater resources are generally weak and reliable information on the proportion of renewable or non-renewable groundwater is sketchy. The IAEA, together with the United Nations Education and Cultural Organization (UNESCO) and International Association of Hydrologists (IAH), is working to improve the understanding of the global distribution and amounts of non-renewable or fossil groundwater. The investigations rely on the use of the labeling properties of isotope data collected from groundwater aquifers worldwide.

Most of the isotope data for global mapping of aquifers were collected over the last four decades as part of the IAEA´s technical cooperation projects. These projects built substantial national and regional scientific capacity and infrastructure while helping to solve practical issues in surface water or groundwater management. At present, there are over 80 operational technical cooperation projects dealing with isotope hydrology in Africa, Asia, and Latin American regions, for an adjusted budget of about US$7 million.

Over the past years, the IAEA has been working very closely with its Member States to bring isotope hydrology into the mainstream of national and international water resource related programmes resulting in a wider use of isotope techniques for water resources management. In central Morocco, isotope results were used to improve a groundwater management model for the Tadla Plain, an important region for agriculture. In Yemen, isotope investigation of groundwater in the Sana´a Basin clearly identified the nature and source of recharge to the shallow groundwater systems. The work advanced understanding of the efficacy of artificial recharge measures, potentially leading to the use of a deeper, fossil aquifer for drinking purposes only.

Of late, the IAEA´s technical cooperation projects in water resources have focused more sharply on partnerships with other development agencies. In Uganda, a project implemented in cooperation with the Austrian Development Cooperation led to the delineation of recharge areas of Chuho springs, near Kisoro town. These springs are being developed as the source of freshwater in the entire southwestern townships. The results of isotope investigations provided unique information critical for the sustainability of the new source of water.

Most of the isotope data for global mapping of aquifers were collected over the last four decades as part of the IAEA´s technical cooperation projects.

In Bangladesh, the IAEA worked in cooperation with the World Bank and the government to help develop sustainable alternatives for safe drinking water supplies. At present, a large part of domestic water supply is obtained from shallow tube wells tapping an aquifer that is contaminated with arsenic. Isotope investigations helped to determine the extent and renewability of a deeper aquifer.

Three technical cooperation projects related to aquifer systems shared by several countries in Africa were recently initiated in collaboration with the Global Environment Facility (GEF), the United Nations Development Programme, and the United Nations Environment Programme. These projects focus on isotope hydrological investigations of the:

  • Nubian Aquifer System shared by Chad, Egypt, Libya and Sudan;
  • Northwestern Sahara Aquifer System shared by Algeria, Libya and Tunisia;
  • Iullemeden Aquifer System shared by Mail, Niger and Nigeria.

Advancing Knowledge about the Nubian Aquifer

The Nubian aquifer, shared by Chad, Egypt, Libya and Sudan, is of significant importance as a source of drinking water and for irrigation. The ancient waters of the Nubian stretch approximately two million square kilometers beneath these four countries of northeast Africa. The aquifer is a significant source of drinking water and irrigation and is the only source of freshwater in Egypt´s western desert, which covers about 67% of the country´s total land area.

Since 2003, the IAEA has been helping the Nubian countries use isotope techniques for mapping water resources. What is known so far is that under present climatic conditions, the Nubian´s groundwater is sparsely recharged by Nile water seepage in a few areas, by precipitation in some mountain regions, and by groundwater influx from the Blue Nile/Main Nile Rift system.

The aim of the IAEA project is to expand and consolidate the scientific knowledge and database on the Nubian and develop a groundwater management plan based on a monitoring network for the aquifer. Setting up a management framework for the aquifer will be an important contribution to the region´s development and eventually lead to sustainable production of drinking water and improved agricultural production.

The IAEA entered into a partnership with Global Environment Facility (GEF) in 2003 to develop a framework for sustainable management of the Nubian Aquifer, using isotope hydrology. The IAEA´s work to help the Nubian countries study and manage shared groundwater supplies recently received a matching grant of $1 million from the GEF, based in Washington, D.C. The grant is being provided via the United Nations Development Program. The GEF funding will extend the scope of the IAEA-supported cooperative programme and will enable the countries that use the aquifer to develop an effective groundwater management plan.

Through these and other channels, the science and applications of isotope hydrology are advancing the world´s knowledge of aquifer systems. With the right information in hand, the right decisions can be made to protect and preserve groundwater resources for generations to come.

Single atom transistor gets precise position on chip

The basic unit of matter could become the basic unit of computing. A lone atom of phosphorus embedded in a sheet of silicon has been made to act as a transistor. (from newscientist1.blogspot.de)
It is not the first single-atom transistor, but it can be much more precisely positioned than its predecessors, potentially making it a lot more useful.
“It’s an absolutely fantastic piece of engineering,” says physicist Bruce Kane at the University of Maryland, who was not involved in the work.
Elaborate production methods would initially prevent single-atom phosphorus transistors from being a worthwhile addition to traditional computers, but they may be necessary one day. The devices could also find an application in futuristic, super-speedy quantum computers.
A transistor is essentially a lump of conducting material sitting between two electrodes that acts as a switch. A pulse of voltage is supplied by a further electrode,”opening” the switch and allowing current to flow through the transistor.

Wiggling atom

Combining transistors on a chip produces logic circuits that can carry out computations. A goal shared by computer chip makers is to keep shrinking the transistor: squeeze ever more onto a single chip and you increase its computational power.
To dictate the exact position of their single atom, Michelle Simmons at the University of New South Wales, Australia, and colleagues started by covering a silicon sheet with a layer of hydrogen. Then they used the tip of a scanning tunnelling microscope to remove hydrogen atoms according to a precise pattern. They exposed two perpendicular pairs of exposed silicon strips plus a tiny rectangle made of just six silicon atoms that sat at the junction between these strips (see diagram, right).
Adding phosphine gas (PH3) and heating caused phosphorus atoms, which are conducting, to bind to these exposed areas of silicon. In the case of the rectangle only one atom inserted itself into the silicon network.
The result was four phosphorus electrodes and a single phosphorus atom.

Boutique operation

One pair of electrodes was separated by a 108-nanometre gap. Creating a voltage between them allowed current to flow between the two perpendicular electrodes – separated from each other by just 20 nanometres, through the single phosphorus atom, which acted as a transistor.
Kane points out that the atomic transistor works at temperatures below 1 kelvin and that fabrication is difficult. “It’s a very slow, boutique operation to make one of these,” he says.
Simmons agrees, but counters that the traditional computer makers may be forced to adopt this technology if they want to make ever smaller chips. “This is one of the only techniques that allows you to make single atom devices,” she says.
Physicist Jeremy Levy of the University of Pittsburgh in Pennsylvania reckons the future of single atom transistors lies in quantum computers. The spin of the electrons in isolated phosphorus atoms could serve as qubits, the quantum equivalent of the bits in today’s computers. Controlling the interaction between qubits requires knowing the exact location of each one. Now that the location of individual atoms can be controlled, the next challenge is to link two of these transistors, Levy says.
