ABUJA Ronald Jones II Womens Jersey , May 14 (Xinhua) -- At least 11 people were feared dead in a suicide bomb attack near a military base in Nigeria's northeastern state of Borno on Wednesday, a military source said Thursday, less than 24 hours after the incident.

The suicide attack, by a female member of Boko Haram, heralded an attempted invasion of Maiduguri Ali Marpet Womens Jersey , capital of the northern Borno State, by the terror group, according to the military source, who was among troops deployed to repel the attack at dusk on Wednesday.

Youth vigilante group members and Nigerian soldiers were among those feared dead, the source said Donovan Smith Womens Jersey , adding a heavy shooting followed the explosion. Residents said they heard explosions and deafening sounds from high caliber weapons before security operatives arrived and cordoned off the area late Wednesday.

While fleeing as Nigerian forces tried hard to repel the attack, the Boko Haram members used their female fighters as shield, leaving some of them behind as they fled from the battlefield, said another security source not authorized to speak to the media on the development.

HOUSTON, Dec. 2 (Xinhua) -- Humble aluminum's plasmonic properties may make it far more valuable than gold and silver for certain applications Vernon Hargreaves III Womens Jersey , reckons a new research done by scientists with Rice University of the United States.

Because aluminum, as nanoparticles or nanostructures, displays optical resonances across a much broader region of the spectrum than either gold or silver, it may be a good candidate for harvesting solar energy and for other large-area optical devices and materials that would be too expensive to produce with coinage metals, said the university based in Houston Chris Godwin Womens Jersey , a city in the U.S. state of Texas, in a press release to announce the latest research result Monday.

Until recently, aluminum had not yet been seen as useful for plasmonic applications for several reasons: It naturally oxidizes, and some studies have shown dramatic discrepancies between the resonant color of fabricated nanostructured aluminum and theoretical predictions.

The combined work of two Rice labs has addressed each of those hurdles in their new publications.

The research by Rice scientists Naomi Halas and Peter Nordlander demonstrates that the color of aluminum nanoparticles depends not only on the size and shape, but also critically on the oxide content. They have shown that the color of an aluminum nanoparticle provides direct evidence of the amount of oxidation of the aluminum material itself.

The labs also characterized the weakening effect of naturally occurring but self-passivating oxidation on aluminum surfaces. " For iron Justin Evans Womens Jersey , rust goes right through," Nordlander said. "But for pure aluminum, the oxide is so hard and impermeable that once you form a three-nanometer sheet of oxide, the process stops." To prove it, the researchers left their disks exposed to the open air for three weeks before testing again and found their response unchanged.

"The reason we use gold and silver in nanoscience is that they don't oxidize. But finally O. J. Howard Womens Jersey , with aluminum, nature has given us something we can exploit," Nordlander said. "In addition to being a cheap and tunable material, aluminum exhibits quantum mechanical effects at larger, more accessible and more precise ranges than gold or silver."

The new findings appeared in the American Chemical Society (ACS) journal ACS Nano.

Cord blood contains almost 10 times as many blood-producing cells so less is needed for a successful transplant. Transplant recipients are less likely to reject a cord blood stem cell transplant than a bone marrow transplant. Cord blood may eventually be used to treat a wider variety of auto-immune and degenerative diseases than is currently being done. Cord blood is donated in advance for anyone who might need it in the future. All routine testing is completed and the unit is stored frozen Carlton Davis Womens Jersey , ready to use. Confirmatory HLA typing and any special testing required is usually completed within 5 days. There is no need to take time to locate a possible volunteer and then determine whether he or she is still willing and able to donate. Cord blood is also less likely to transmit certain common viruses like Epstein-Barr virus and cytomegalovirus, potentially lethal infections for transplant recipients. Cord blood transplantation exposes the patient to one of the rare genetic disorders of the immune system or blood. The quantity of stem cells for transplantation is less than that in peripheral blood or bone marrow. This problem is greater for adults and adolescents as they need comparatively more quantity of stem cells for transplant. The stem cells found in umbilical-cord blood have the ability to turn into red or white blood cells or blood-clotting cells. Stem cells have been shown to grow new blood vessels around narrowed or damaged arteries in the limbs and restore impaired blood flow. Cord blood is also less likely to transmit certain common viruses, like Epstein-Barr virus (EBV) and cytomegalovirus, potentially lethal infections for transplant recipients. Cord blood stem cells have a lower risk of graft versus host disease when compared to bone marrow transplants therefore allowing for a greater range of finding a donorrecipient. Umbilical cord blood stem cells can be used in transplants to treat a variety of pediatric disorders including leukemia, sickle cell disease Vita Vea Womens Jersey , and metabolic disorders. Cord blood has been used in the treatment of more than 80 different diseases so far. The most common disease category has been leukemia. Cord blood stem cells are younger, they have better proliferative properties - they are able to regenerate more and faster than bone marrow stem cells. The use of umbilical cord blood stem cells to treat previously identified familial illness in a first degree relative provides a primary indication for collection and banking, the procedure and storage is c.
