Tere jaisa yaar kahan
Kahan aisa yaarana
Yaad karegi duniya
Tera mera afsana 

Tere jaisa yaar kahan
Kahan aisa yaarana
Yaad karegi duniya
Tera mera afsana 

Meri zindagi sawaari
Mujhko gale lagake
Baitha diya falak pe
Mujhe khaat se oothake 

Meri zindagi sawaari
Mujhko gale lagake
Baitha diya falak pe
Mujhe khaat se oothake
Yaara teri yaari ko
Maine to khuda mana
Yaad karegi duniya
Tera mera afsana 

Mere dil ki yeh dua hai
Kabhi door tu na jaaye
Tere bina ho jeena
Woh din kabhi na aaye 

Mere dil ki yeh dua hai
Kabhi door tu na jaaye
Tere bina ho jeena
Woh din kabhi na aaye
Tere sung jeena yahan
Tere sung mar jaana
Yaad karegi duniya
Tera mera afsana 

Tere jaisa yaar kahan
Kahan aisa yaarana
Yaad karegi duniya
Tera mera afsana

Nanoelectronics

In 1965 Gordon Moore observed that silicon transistors were undergoing a continual process of scaling downward, an observation which was later codified as Moore's law. Since his observation transistor minimum feature sizes have decreased from 10 micrometers to the 28-22 nm range in 2011. The field of nanoelectronics aims to enable the continued realization of this law by using new methods and materials to build electronic devices with feature sizes on the nanoscale.
The volume of an object decreases as the third power of its linear dimensions, but the surface area only decreases as its second power. This somewhat subtle and unavoidable principle has huge ramifications. For example the power of a drill (or any other machine) is proportional to the volume, while the friction of the drill's bearings and gears is proportional to their surface area. For a normal-sized drill, the power of the device is enough to handily overcome any friction. However, scaling its length down by a factor of 1000, for example, decreases its power by 1000³ (a factor of a billion) while reducing the friction by only 1000² (a factor of "only" a million). Proportionally it has 1000 times less power per unit friction than the original drill. If the original friction-to-power ratio was, say, 1%, that implies the smaller drill will have 10 times as much friction as power. The drill is useless.
For this reason, while super-miniature electronic integrated circuits are fully functional, the same technology cannot be used to make working mechanical devices beyond the scales where frictional forces start to exceed the available power. So even though you may see microphotographs of delicately etched silicon gears, such devices are currently little more than curiosities with limited real world applications, for example, in moving mirrors and shutters.Surface tension increases in much the same way, thus magnifying the tendency for very small objects to stick together. This could possibly make any kind of "micro factory" impractical: even if robotic arms and hands could be scaled down, anything they pick up will tend to be impossible to put down. The above being said, molecular evolution has resulted in working cilia, flagella, muscle fibers and rotary motors in aqueous environments, all on the nanoscale. These machines exploit the increased frictional forces found at the micro or nanoscale. Unlike a paddle or a propeller which depends on normal frictional forces (the frictional forces perpendicular to the surface) to achieve propulsion, cilia develop motion from the exaggerated drag or laminar forces (frictional forces parallel to the surface) present at micro and nano dimensions. To build meaningful "machines" at the nanoscale, the relevant forces need to be considered. We are faced with the development and design of intrinsically pertinent machines rather than the simple reproductions of macroscopic ones.
All scaling issues therefore need to be assessed thoroughly when evaluating nanotechnology for practical applications.
Research is ongoing to use nanowires and other nanostructured materials with the hope to create cheaper and more efficient solar cells than are possible with conventional planar silicon solar cells^.It is believed that the invention of more efficient solar energy would have a great effect on satisfying global energy needs.
There is also research into energy production for devices that would operate in vivo, called bio-nano generators. A bio-nano generator is a nanoscale electrochemical device, like a fuel cell or galvanic cell, but drawing power from blood glucose in a living body, much the same as how the body generates energy from food. To achieve the effect, an enzyme is used that is capable of stripping glucose of its electrons, freeing them for use in electrical devices. The average person's body could, theoretically, generate 100 watts of electricity (about 2000 food calories per day) using a bio-nano generator^. However, this estimate is only true if all food was converted to electricity, and the human body needs some energy consistently, so possible power generated is likely much lower. The electricity generated by such a device could power devices embedded in the body (such as pacemakers), or sugar-fed nanorobots. Much of the research done on bio-nano generators is still experimental, with Panasonic's Nanotechnology Research Laboratory among those at the forefront.

har ek friend jaruri hota hai........................

Chai ke Liye jaise toast hota hai--Vaise har ek friend zaroori hota hai
Aise har ek friend zaroori hota hai

Koi subah paanch baje neend se jagaye

Koi raat ko teen baje jaan bachaye

Ek teri kadki mein sharing kare

Aur Ek tere budget mein sneak in kare

Koi nature se guest koi host hota hai

Par har ek friend zaroori hota hai


""Ek ghadi ghadi kaam aaye par kabhi kabhi call kare

Ek kabhi kabhi kaam aaye aur ghadi ghadi call kare""


Gossip ka koi ghoomta phirta satellite

Koi sath rahe toh kar de sab alright

Koi effortless koi forced hota hai

Lekin har ek friend zaroori hota hai

Chat Room friend koi classroom friend

Koi bike pe race wala vroom vroom friend

Shopping mall wala shopping friend

Koi Exam hall wala copying friend

Movie buddy groovy buddy

Hi buddy--Bye buddy ----Joke buddy Poke buddy
Gaana Buddy Shaana buddy ---Chaddi Buddy Yaar Buddy
Kutte --kamine---
Everybody---Sab buddy
A to Z

Gin din ke naam bheja Roast hota hai

Par har ek friend zaroori hota hai

Lekin har ek friend zaroori hota hai

Jindagi...yani kya
Ek dhundli si shaam..,
4 Frnds...
4 Cup chai..
1 Table..
Jindagi...yani kya
1 innova car,
7 Frnds, aur..
1khula lamba pahadi Rasta..
Jindagi...yani kya
1 dost ka ghar...
Halki si Baarish, 1 pkt cigarette, 1 bottle vodka...
aur dher saari baatein..
Jindagi...yani kya:
College ke dost,
Bunk Kiya hua Lecture.,
Two curting tea, I kachori 2 samose aur bil par hone wala jagada..
Jindagi...yani kya,
Phone utate hi padne wali dost ki meethi se gali..
aur
Sorry kahene par...1aur gaali .
Jindagi...yani kya
Kutch saalon baad...
Aachanak purane doston ki yaad... Ek sms...,
Dhundlee padi kuch bhigi yadein
aur...
Aankho me aaye hue aansoon !!!
Dedicated to all u friends... who have given me such Great Moments in life....!

Aapki dosti ki ek nazar chahiye,
Dil hai beghar usey ek ghar chahiye,
bas yuhin saath chalte raho e dost,
Yeh dosti humein umar bhar chahiye…

friends sahyari

Jaane Wale Aur Honge,
Hum To Yahi Reh Jaenge,
Paana Chahoge Hame Kabhi,
Aas Paas Mil Jaenge,
Aawaaz Doge Ek Baa,
...Kabr Se Bhi Uth Kar Aaenge,
Mehfil Sazaa Kar To Dekho Hamaare Bagair,
Joote Sar Par Tumhare Lagaenge,
Ik Dosti Nibhani Sikhi Yaara,
Is Daulat Ko Na U Gawaenge,
Rooth Jaenge Tere Saare Dost,
Kabhi Loveleen Ko Na Sang Apne Paenge,
Kar Shak Na Humpe Itna Tu,
Hum Roothe To Rab Bhi Na Mana Paenge …
