ZLD (zero liquid discharge): A life saving initiative

Everyone knows the importance of water. Because thirst can kill. But then we tend to use it recklessly just as the smokers smoke knowing it's repercussions.

I won't go on to elaborate the stastistics as frequent news of death tolls serves adequately as an alarm for not too much of it is left for drinking.

With saving water campaigns falling flat the situation seems even worse. To this very problem has come a solution which ensures zero water discharge i.e. the system eliminates solid and wastes dissolved in the given liquid and yields distilled water in the process. The system is called Zero liquid discharge abbreviated as 'ZLD'.

With numerous recycling processes already in work what gives this process an edge over the rest is it's higher efficacy. For instance, for the first time in India this system is being deployed in jamshedpur, a small city in the state of jharkhand known for it's sprawling steel industries as well state of the art civic management system for which it's been lauded in the past. The city has a private municipality JUSCO(Jamshedpur utility and service corporation limited) which has been relentlessly working towards making life of the people of the city as comfortable, modern and healthy as possible. The JUSCO in this effort has taken a new step by incorporating ZLD which is likely to start working by the end of this year. "We will be processing waste and sewage water and the system is expected to yield 40 million water per day for industrial use" said the DGM(water management) of JUSCO.

This is the high time the rest of the states should take away the best from this experiment and do their part in saving as much of water as possible as the potable amount of it is limited and believe me it's too less to serve the coming generation.

Right to Internet access: a beginning as India soon to get an annual internet subscription for 100 rupee.

  Data Wind a Canadian company which caught the eye with it's  Aakash tablets selling at throwaway prices that came out of nowhere and jolted the Indian smartphone industry is all set for yet another foray in the telecom industry with it's plan to provide Internet service for 99 per annum.

   Suneet Tuli, CEO of the company said that it has already applied for VIRTUAL NETWORK OPERATOR licence and will soon be able to take this service to every nook and cranny of the country. "We are primarily focused towards making internet available to the 100 crore rural population of India who still don't have access to it owing to the skyrocketing costs of data. Furthermore, we will be using existing infrastructure and thus reducing installation cost. Also, it usually takes about 1-2 minutes for a page to load on  a regular 2g network whereas our patented technology is capable of loading it in 6-7 sec. a considerable edge over the former" he added.

  VNOs (virtual network operrators) are retailers of telecom services who buy bulk minutes from telecom operators and sell them under a different brand. They don't own any network.

    Guys, This could well be seen as the beginning of a much needed change in the Indian telecom industry challenging the unabashed and wilful market trend set by the existing Indian telecom companies and therefore would surely create price rigidity. 
   
  Also, this is the advent of right to internet access in India and that we should welcome this initiative wholeheartedly taking into account the revolutionary catalysis this technology could trigger as it's been seen in countries like Sweden and Estonia.

  Yeah I know! What's going on in your mind. When can we leverage? right?

   Guys, we are gonna have to wait until the end of this year.  

If you can't see, surely you can see through now.

                                               

Our body is made up of anxiety to ple organs,each equipped with unique functions essential for our body to work properly. One such organ is eye which lets us observe the world visually. Moreover every organs performing observational tasks has an emotional response attached to it. For instance, a child with his mother has a feeling of care which he observes phonetically, visually and physically as he listens to the bed time stories, sees her smiling and being cuddled respectively. Therefore the significance of any of the organs can not be compared with the other.

But what if you don't have one. What if you are not able to read what I have written here. What if you are blind. Things become challenging right! The affected begin to develop their own way of dealing with such challenges. One such revolutionary solution was developed for reading texts on paper was Braille that zapped the inability of a visually impaired person to read.

Adding to this a Microsoft employee has developed something which could prove to be boon for the unsighted, a sun-glass which can read for you, watch for you, stare for you and can sometime even stalk for you.

Yeah I understand you are anxious to know about its working. Therefore to make things easier I have got a video for you. Watch it and possibly let those people know about it who are in need of this device.

How ANALOG COMPUTERS work?

An analog computers, works by measuring voltages and currents rather than by the process of counting. An analog computers works on supply of continuous electrical signals and display outputs continuously. Side rule is an example analog device in which numbered as expressed as distances. Another example of analog computers is a speedometer of an automobile which continuously displays outputs in the form of speed of the vehicle as it receives continuous signals. On the other hand milometer (displaying distance covered by the vehicle) is a digital device. Thus, an analog computer works by establishing analogy between two quantities one of which is essentially continuous like electrical signals or electrical pulses. The machine has a very limited memory and can perform only a certain types of calculations, which makes it specialized machine suitable for engineering and scientific calculations. An analog computer is basically a device for solving ordinary differential equations and can be used in solution of those problem which can be converted to a differential equation. The accuracy of these machines are low although these are faster in speed as compared to digital machines because all the tasks performed in this machine are in parallel.

Thus, we conclude an analog computer is a special purpose computer capable of solving any physical operation which can be represented as an ordinary differential equation. This computer is faster than a digital computer but can give an accuracy of not more than 99%.

Since analog computer is a special purpose device, so most of the computer are digital.In fact the word COMPUTER has become synonym of a digital computer.
