Nano-sized batteries to power mobiles.....

  

WASHINGTON: An Indian-origin scientist-led team in the US has packaged lithium ion batteries into single nano wire, which they claim could soon be a rechargeable power source for new generations microelectronics.
Prof Pulickel Ajayan and colleagues at Rice University claim their creation is as small as such devices can possibly get, in their research published in American Chemical Society journal 'Nano Letters'.

In their research, the scientists tested two versions of their battery.

The first is a sandwich with nickel or tin anode, polyethylene oxide electrolyte and polyaniline cathode layers; it was built as proof that lithium ions would move efficiently through anode to electrolyte and then to supercapacitor-like cathode that gives the device ability to charge and discharge.

MICROSOFT WINDOWS 8

Let's begin to the future

                  At the D9 Conference,Microsoft demonstrated the next generation of Windows, internally code-named “Windows 8,” for the first time. Windows 8 is a reimagining of Windows, from the chip to the interface. A Windows 8-based PC is really a new kind of device, one that scales from touch-only small screens through to large screens, with or without a keyboard and mouse. 
                           The demo showed some of the ways we’ve reimagined the interface for a new generation of touch-centric hardware. Fast, fluid and dynamic, the experience has been transformed while keeping the power, flexibility and connectivity of Windows intact. 
Here are a few aspects of the new interface we showed today:
 •
Fast launching of apps from a tile-based Start screen, which replaces the Windows Start menu with a customizable, scalable full-screen view of apps.
Live tiles with notifications, showing always up-to-date information from your apps.
Fluid, natural switching between running apps.
Convenient ability to snap and resize an app to the side of the screen, so you can really multitask using the capabilities of Windows.
Web-connected and Web-powered apps built using HTML5 and JavaScript that have access to the full power of the PC.
Fully touch-optimized browsing, with all the power of hardware-accelerated Internet Explorer 10.


          And  also showed effortless movement between existing Windows programs and new Windows 8 apps. The full capabilities of Windows continue to be available to you, including the windows Explorer and Desktop, as does compatibility with all Windows 7 logo PCs, software and peripherals.





                Although the new user interface is designed and optimized for touch, it works equally well with a mouse and keyboard. Our approach means no compromises — you get to use whatever kind of device you prefer, with peripherals you choose, to run the apps you love. This is sure to inspire a new generation of hardware and software development, improving the experience for PC users around the world.

             Windows 8 apps use the power of HTML5, tapping into the native capabilities of Windows using standard JavaScript and HTML to deliver new kinds of experiences. These new Windows 8 apps are full-screen and touch-optimized, and they easily integrate with the capabilities of the new Windows user interface.

The Last freedom countary ....

THE WORLD'S NEWEST NATION 
"SOUTH SUDAN"
                      The Republic of South Sudan is at the tail end of economic development. All the indices of human welfare put its citizens at the bottom of all humanity. The independence we are now celebrating transfers the responsibility for our destiny and reversing the tide underdevelopment to our own hands. The challenges are great but we must begin the task of nation building immediately.
       
The African Union (AU) has admitted South Sudan as its 54th member, marking another recognition for the world’s newest nation.
The African Union said it received the requisite number of written communications, including from Sudan, supporting the admission of South Sudan to the continental body as the 54th AU Member State.
South Sudan got its independence from Sudan on July 9 following decades of conflict that left millions dead.
Its sovereignty officially broke Africa’s largest nation into two, the result of a January referendum overwhelmingly approved by voters.
South Sudan is the latest addition to the AU since Eritrea joined in 1993 following its split from Ethiopia.
South Sudan became the 193rd member of the United Nations on July 14.

       Flag of the Republic of South Sudan flying high in the sky.
                One of the economic sectors we must prioritize is agriculture. Our country has vast fertile arable land and several months of rainfall every year. We have the potential to become the breadbasket of the region. We should never import basic food commodities we are capable to produce locally. Let us be ready to make our hands dirty but fill our lives.


               We will also pursue investment in other sectors such as tourism, hydroelectricity generation, physical infrastructure development, social services and amenities, hospitality, mining, forest resources, food processing and sports, to mention but a few.


                     The eyes of the world are on us. Everyone is watching us closely to see whether our first steps in nationhood are steady and confident. We must rise to the occasion and prove that we are capable of playing our honest part in the international community of nations. What are you doing for your country today?

South Sudan's first female car mechanics

          The culture of Sudan makes women  subject to men in many ways. Women even have to kneel at the feet of their husbands when then they bring water to them.


            Three young women are trying to break through the barriers of their culture by training to become mechanics. Once they graduate they will be the first women to work in this trade in Sudan's history. 

                   The Nilotic peoples — the Dinka, Nuer, Shilluk and others — first entered South Sudan sometime before the 10th century. During the period from the 15th century to the 19th century, tribal migrations, largely from the area of Bahr el Ghazal, brought these peoples to their modern locations. The non-Nilotic Azande people, who entered South Sudan in the 16th century, established the region's largest state. The Azande are the third largest ethnic group in South Sudan. They are found in the Maridi, Yambio, and Tambura districts in the tropical rainforest belt of Western Equatoria and Western Bahr el Ghazal. In the 18th century, the Avungara people entered and quickly imposed their authority over the Azande. Avungara power remained largely unchallenged until the arrival of the British at the end of the 19th century. Geographical barriers prevented the spread of Islam to the southerners, thus enabling them to retain their social and cultural heritage as well as their political and religious institutions.
