Scientists worry about Space Junk

August 9, 2011 1 comment

space debris, satellite, science, astronomy, nasaSpace junk refers to man-made trash floating in space including spent rocket stages, malfunctioning satellites, spanners, nuts, bolts, and small parts of spacecraft.

The United Nations Committee on the Peaceful Uses of Outer Space defines space debris as “all man-made objects, including fragments and elements thereof, in Earth orbit or re-entering the atmosphere, that are non-functional”.

More than 17,000 objects of a size greater than 10cm reside in Earth’s orbit.

New research identifies more than 60 objects at a height of about 850km from earth, and two thirds of those weigh more than three tonnes each and moving at speeds of up to 7.5km/s.

More satellites in orbit tend to breed more space junk, as illustrated by the 2009 collision of a defunct weather satellite and an Iridium telecom satellite, which left thousands of additional junk pieces of debris in orbit.

NASA researchers say there could be a relatively cheap solution for dealing with this “space junk”: aim a medium-powered laser into space and push any objects on a collision course out of harm’s way.

“Spacecraft are supposed to have enough ‘gas’ in their tanks to propel them downward toward the atmosphere when their life cycle is concluded,” say Stanford researchers Lawrence Wein and Andrew Bradley. “But international compliance, while perhaps greater than 50 percent, is not extremely high.”

“It appears that if full compliance of the 25-year spacecraft de-orbiting guidelines can be achieved within the next few decades, then the lifetime risk from space debris may be sustainable at a tolerable level,” write the authors. They call for focusing future policy on achieving full compliance with rules to get equipment out of orbit, and making it taboo to intentionally blow up equipment already in orbit.

Debate about the most appropriate method to deal with space debris is ongoing on many science forums. Space junk is of growing concern but the good news is that scientists are working on solutions to reduce the debris in space so that International Space Station and useful satellites are not destroyed accidentally.

Sony Ericsson posts losses in second quarter, 2011

July 15, 2011 Leave a comment

Sony Ericsson post losses 2011, mobile phone industry Sony Ericsson has declared its financial results for the last quarter (April – June 2011), blaming poor performance on a shortage of components in the aftermath of the earthquake, tsunami and nuclear disaster in Japan in March.

The company sold 7.6 million handsets in the 3 month period, but it had expected to sell between eight and eleven million.

But it’s not all bad news, with Sony Ericsson managers insisting that the hard times are behind it, and forecasting bigger sales for the second half of the year.

Chief executive Bert Nordberg said, “There might be some minor spillover. In our planning this shortage is behind us.”

Sony Ericsson expected big things of 2011, unveiling a strong line up of smartphones at this year’s Mobile World Congress, including the Sony Ericsson Xperia Arc and the long-awaited Xperia Play PlayStation phone.

Murdoch’s Clout should be reduced, Media Tycoon

July 13, 2011 Leave a comment

To avoid another News of the World crisis, media influence should be limited, a media tycoon has been quoted as saying.

Rupert Murdoch’s News Corp media empire has become too powerful and regulators should reduce its influence and prevent it from taking over British pay TV operator BSkyB , Russian tycoon Alexander Lebedev said on Tuesday.

“I don’t think it should be that big because then it has too much influence and too much money,” Lebedev, the Russian former spy who now owns several British newspapers including the Independent and London’s Evening Standard, which have been critical of Murdoch since the scandal broke.

“I don’t think he needs more,” Lebedev said, referring to whether Murdoch’s News Corp should be allowed to bid for the 61 percent of BSkyB it does not already own. “I don’t see the point; I think it is contrary to the public interest, that is what I think.”

Murdoch was fighting to contain the crisis engulfing his media empire on Tuesday after allegations surfaced that journalists at several of his News Corp papers had targeted former British Prime Minister Gordon Brown.

“I don’t think mankind gains anything from living under huge financial or media empires: they start to rule the world, they become stronger than the regulators,” Lebedev said, adding regulators should make “more Murdochs”.

When asked if that meant Murdoch’s media empire should be split up he said: “Limiting its influence in the British media, limiting and reducing.”

SEO News post Google Panda Update

June 7, 2011 Leave a comment

Google Panda update seo newsGoogle has always stated that their search algorithms are set out to favor websites with useful content.

But what is useful content?

Google uses certain parameters to determine whether content on a site is useful or not. The problem Google has been dealing with over the years is how to identify websites that appear on top of their search results yet they don’t have useful or original content.

The February Panda update was meant to eliminate this non-useful websites from top search results.

Google identifies poor websites as sites with:
•    Excessive ad-to-content ratios
•    Poor external links (from bad websites)
•    Duplicate content

Content that generally does not add value to the web community.

But this is not news.

Nofollow and Noindex Tags

What is new in the Panda update is that use of nofollow and noindex tags will have negative effect on a website ranking.

What Google is implying is that if you don’t want some content to be seen by search engines, then don’t publish it. If you don’t want bots to follow a certain link, then don’t link to that web page, else your site will be demoted.

Search engine optimization is never easy. What was standard seo practice last year will lead to drop in web page position when applied today.

To beat the panda update, write good original content and don’t be sneaky.

Smartphones Dominating the Mobile Phones Market in 2011

May 8, 2011 Leave a comment

Smartphones Mobile Phones Market statistics 2011The latest mobile phone data study conducted by the International Data Corporation (IDC) shows a very significant growth in 2011. The contributing factor for this large growth for a span of just a year was the introduction of the smartphones in the mobile phone market . The International Data Corporation Worldwide Mobile Phone Tracker data showed that almost a 20% growth was made in over a year. An estimate of 371 million mobile phones sales last year.

Although the smartphones are what’s in demand nowadays, mobile phone experts concluded that other types of phones will not become obsolete in the near future since there are still demands of it from all over the world. Smartphones’ contribution became the more significant growth but other types of phones have contributed as well.

The studies showed that many mobile markets have contributed to this sudden growth. They mentioned particular countries where the growth was most significant. And these countries were a big help in this change. It is said that the shared markets are most likely to gain from the sudden growth.

The reason for the sudden demand in smartphones may be due to its affordability and the larger number of consumers from a wider range. This made smartphone producers to step up and grab the opportunity to increase their sales.

IDC’s Kevin Restivo explained that growth in mobile market is not just mainly because of the top companies but as well as the companies outside this cluster. It is still too soon to say that market growth is because of these shared gains.

Companies should not claim this success as a sole contribution because all companies, big or small have a contribution in this growth.

In conclusion, IDC stated that smartphones has a bright future in the mobile phone market and may become the main factor in contributing to the market growth worldwide. The makers of other types of phones may now have the tendency to go with the same trend to cope up with this fast growth.

The ICT Sustainability Index was just released by the IDC. It ranks the capacity of the group of 20 nations to minimize the emission of carbon dioxide with the usage of Information and Communication Technologies.
