J&J consumer health segment recalls infant Tylenol

Recall-plagued Johnson & Johnson is pulling all infant Tylenol off the U.S. market because some parents have had problems with redesigned bottles,There are 240 distinct solutions of the Soma cubepuzzle, introduced three months ago, that the company touted as a big safety improvement to make measuring doses easier.

Instead, 17 parents or caregivers have complained that a protective cover on the top of the bottles didn't work correctly. It's meant to limit how much of the liquid pain and fever reducer can be drawn into a plastic syringe. But when those consumers inserted the plastic syringe, it pushed the protective cover, or flow restrictor, into the bottle.

J&J's McNeil Consumer Healthcare unit, which has had about 25 product recalls since September 2009, said Friday that it is recalling all 574,000 bottles of grape-flavored, liquid Infants' Tylenol from stores nationwide.

"Today's news about the Infants' Tylenol recall is clearly disappointing after all the progress that McNeil has been making to ensure its products meet the highest level of quality and consumer satisfaction," CEO William Weldon said in a statement.

Last spring,There are 240 distinct solutions of the Soma cubepuzzle, Weldon told shareholders at J&J's annual meeting that the company was simplifying the packaging to "help a mom, dad or caregiver ensure the correct dosing." Weldon told The Associated Press then that he thought the new design would become the industry standard.

Infants' Tylenol is one of the first nonprescription medicines reintroduced after all the recalls and an ongoing factory shutdown have kept most McNeil medicines off the market,Choose from our large selection of cableties, some for nearly 2 years. That's cost the company well over $1 billion in lost revenue,moldmaker/ plus many millions to rebuild one factory and upgrade others.

McNeil spokeswoman Bonnie Jacobs said it was too soon to say when the product will return to the market.

"We are looking at various alternatives for the redesign of the dosing system and will set a timeline ... once we've reviewed all the options," she said.

While babies are particularly vulnerable to excessive doses of medicine,Sika tooling & Composites develops and produces tailor-made synthetic resins, J&J said there have been no reports of anyone being harmed.

The new infant Tylenol bottle comes with a plastic syringe that's to be inserted into the flow restrictor at the top to help measure the right dose. The syringe has an opening in the tip but no needle. Consumers are to insert the tip of the syringe into the flow restrictor, turn the bottle upside down and then draw out the right dose using the milliliter markings on the syringe. That's then squirted into the baby's mouth.

McNeil changed the design to make it easier to get the dose right and to limit spillage if the bottle is knocked over, McNeil spokeswoman Barbara Montresor said. The prior version had an open-topped bottle and a dropper with a flexible bulb at the top, similar to a turkey baster.

McNeil is part of the consumer health business segment at J&J, which is based in New Brunswick, N.J. The company's prescription drug and medicial device divisions each have issued at least two recalls in the last couple years.

Reasons for the recalls have included nauseating package odors, small glass or metal particles in liquid medicines and wrong levels of active ingredients.

Scientists design 3D thin-film silicon solar-cells with better efficiency potential

Researchers from the Academy of Sciences of the Czech Republic and experts from the Swiss-based group Oerlikon Solar Lab targeted the development of a long-term option for high-yield but low-cost industrial production of solar panels from raw materials. According to the team, these can be found in amorphous silicon solar cells and microcrystalline silicon tandem cells. The upshot is energy that is much more efficient.

However, Milan Vanecek, who led the photovoltaic group at the Institute of Physics in Prague, pointed out a weakness of these cells: the stable panel efficiency is not nearly as high as the efficiency generated by crystalline wafer-based silicon, the item du jour.

'To make amorphous and microcrystalline silicon cells more stable, they're required to be very thin because of tight spacing between electrical contacts, and the resulting optical absorption isn't sufficient,' explains Dr Vanecek. 'They're basically planar devices. Amorphous silicon has a thickness of 200 to 300 nanometres, while microcrystalline silicon is thicker than 1 micrometre.'

This sophisticated design, however, is centred on optically thick cells that are 'strongly absorbing', and the distance between the electrodes is steady.

'Our new 3D design of solar cells relies on the mature, robust absorber deposition technology of plasma-enhanced chemical vapour deposition, which is a technology already used for amorphous silicon-based electronics produced for liquid crystal displays,' the Czech researcher says. 'We just added a new nanostructured substrate for the deposition of the solar cell.'

The researchers explain that the nanostructured substrate encompasses zinc oxide (ZnO) nanocolumns or a honeycomb array of microholes or nanoholes etched into the transparent conductive oxide layer. The team calls the latter design 'Swiss cheese'.

'This latter approach proved successful for solar cell deposition,' Dr Vanecek points out. 'The potential of these efficiencies is estimated within the range of present multicrystalline wafer solar cells, which dominate solar cell industrial production. And the significantly lower cost of Micromorph panels, with the same panel efficiency as multicrystalline silicon panels (12% to 16%), could boost its industrial-scale production.'

The team said that they will continue their work to optimise and raise efficiency even further.

Conclusion

Conclusion



The Xoom represents a strong start in the tablet space for Motorola. The company has

outfitted with the Xoom with all of the specifications you'd want in a tablet. It's

super fast, well built and it's currently the only tablet that runs Android 3.0.

Honeycomb ushers in a tablet specific Android OS, which thankfully does not feel like

a misplaced phone OS. Google has incorporated parts of Android that help to provide

for a familiar experience and have a high appeal to those who enjoy personalizing

their device(s). There are some gaps in the OS that make it feel incomplete and the

lack of tablet specific apps in the Android Market is disappointing, but not

surprising. With a slew of tablets expected to hit the market in 2011, the apps will

come. A number of differentiating features (Flash support, 4G, microSD expansion) are

all coming soon, but not available now. This makes for an experience that might be as

refined as one would expect, but it's a terrific beginning. Google and Motorola will

move quickly to address the missing pieces.

In the end, the Motorola Xoom is an extremely capable tablet and one that will

certainly improve over time. If you are ready for bumps in the road that accompany

early adoption, there is plenty to like about the Motorola Xoom.
