zte nubia z5

The Nubia Z5 runs on Android 4.1, and it's powered by a 1.5GHz quad-core processor and a 2,300mAh battery.

The handset comes in black or white, and has a 5-inch 1080p touch screen with a 1,920x1,080-pixel resolution and 443ppi. The display is manufactured by Sharp. Its aluminum uni-body design measures 5.43-inches tall, 2.71-inches wide, and has a thin, 0.3-inch profile. And at 4.44 ounces, it's more lightweight than most standard 5-inch smartphones. On the back there is a 13-megapixel camera with LED flash, and it includes features like panoramic and continuous shooting. On the front is a 2-megapixel camera. Inspite of great features it also includes 2GB of memory, 32GB of storage space, Dolby sound technology, and free backup to a private cloud service. The device costs about $554.26 (3,456 yuan) and is ZTE's flagship phone for the season. Ahh ,i think that would make it a beast in the high end mobile market to win the hearts of the people. wait friends thier's anothe…

ipad 5 coming in march 2013

iPad 5 rumored to launch in march 2013
finally  the rumors of the fifth-generation iPad (iPad 5) and iPad Mini 2 have surfaced in china. the leaks are to be believed, the iPad 5 will be thinner and lighter, and also feature a new design that’s similar to the iPad Mini . 
The iPad Mini 2 will keep the same 7.9-inch display, but make the jump to Retina resolution (2048×1536) and also move to the A6X SoC (currently in the iPad 4).
The new fifth-generation iPad will be 4mm shorter, 16mm narrower, and 2mm thinner than the fourth-gen iPad — in other words, it’ll look a lot like the iPad Mini, with its narrower portrait bezel. By decresing 2mm in depth, the iPad 5 would be just 7.4mm.  This size reduction will reduce the weight of the iPad 5, but it might also impact battery life, unless Apple has a new technology hidden to give the users with more power in minimum possible size.

The iPad Mini 2 is probably a more exciting proposition. If the rumors are correct, this diminutive iPad …

Reservoirs can make local flooding worse, says study

Researchers say that large man-made reservoirs can increase the intensity of rainfall and could affect flood defences.

The scientists found that rain patterns around bodies of water in Chile were much higher than in similar areas without them. This "lake effect" could overwhelm flood defences which are often built without taking it into account. The study has been accepted for publication in the journal Hydrology. Stormy edge
Previousresearchin this field has focused on the impact of dams on local climates. There is evidence that standing bodies like reservoirs and lakes can alter rain patterns by increasing the amount of water that evaporates.
Some experts believe that you also get circulating air patterns in the atmosphere above the boundary between the water and the land and this can initiate thunderstorms and showers. “” The impact can be significant. One study showed that extreme precipitation increased by 4% per year after dams were built. In this latest work, researc…

Fish attracted to same-sex flirts

Female fish are attracted to males that "flirt" with other males, a study has found. Scientists in Germany studied the behaviour of tropical fish Poecilia mexicana, known as Atlantic mollies. The female fish are known to "mate copy" - preferring to mate with males they have seen interacting sexually with other fish. Researchers found that females still took an interest in males when their flirtations were with the same sex. Dr David Bierbach from the University of Frankfurt, Germany, led the research that is published in the Royal Society journal Biology Letters. In the paper, researchers refer to homosexual behaviour in the animal kingdom as a "conundrum". "Male homosexual behaviour can be found in most extant classes across the animal kingdom, but represents a Darwinian puzzle as same-sex mating should decrease male reproductive fitness," they wrote. However, many animals that engage in homosexual behaviour have also been observed mating with…
Microcontroller Basics

• A microcontroller is a small, low-cost computer-on-a-chip which usually
– An 8 or 16 bit microprocessor (CPU).
– A small amount of RAM.
– Programmable ROM and/or flash memory.
– Parallel and/or serial I/O.
– Timers and signal generators.
– Analog to Digital (A/D) and/or Digital to Analog (D/A) conversion.
• Often used to run dedicated code that controls one or more tasks in the
operation of a device or a system.
• Also called embedded controllers, because the microcontroller and support
circuits are often built into, or embedded in, the devices they control.
• Devices that utilize microcontrollers include car engines, consumer electronics
(VCRs, microwaves, cameras, pagers, cell phones .. ), computer peripherals
(keyboards, printers, modems.. ), test/measurement equipment (signal
generators, multimeters, oscilloscopes …).
• Microcontrollers usually must have low-power requirements (~. 05 - 1 W as
opposed to ~10 - 50 W for general purpose desktop CPUs) since many devic…


In order to escape from a metal being bombarded by
light, an electron requires an amount of energy qF
and emits an energy hn. The work function F, is the
minimum amount of energy needed to cause an
electron to leave the metal. It is a constant for each
metal. Tungsten: 4.5 eV.
           E = hv - qF  (must know)
Em = maximum energy of emitted electrons [J]
h = Planck's constant, 6.63×10-34 J-s
v= (nu) frequency [Hz]
q = electron charge 1.6022 × 10-19 [c]
qf = (phee) the work function of the metal [eV]

Have Venusian volcanoes been caught in the act?

Have Venusian volcanoes been caught in the act?

Six years of observations by ESA's Venus Express have shown large changes in the sulphur dioxide content of the planet's atmosphere, and one intriguing possible explanation is volcanic eruptions.
