Direction: In many of the process control applications, the purpose of control system is to keep the output (controlled variable) almost constant in spite of changes in load. Mostly in continuous processes the set point remains constant for longer time. Such an operation is called 'Regulator Operation'. The set point generated, and the actual values from sensors are given to a controller. The controller compares both the signals, generates error signal which is utilized to generate a final signal as controller output. The controller output is finally utilized to physically change the values of manipulated variable to achieve stability. The above action is achieved with the help of final control elements. They are operatable either with electrical, pneumatic or with hydraulic signals. The system that serves good for servo operation will generally not be the best for regulator operation. Large capacity or inertia helps to minimize error here, whereas it makes the system sluggish in case of servo operation.
Q. How is the constant value maintained ?

Direction: The term " inform" has been derived from the Latin word "informare ", which means giving shape to something. Information adds something new to our awareness and removes the vagueness of our ideas. It equips us with necessary knowledge to help us in our pursuits be it material or spiritual ! This can be a handy tool in bringing transparency and accountability in public life thus serving a larger interest. According to transparency international report, ours is one of the most corrupt nations of the world. One way to take this problem is to equip citizens with right to information. The Right to Information has, in fact, received judicial recognition as a part of the international rights to free speech and expression. The Supreme Court, for instance, had in a judgement in 1975 observed; in a government of responsibility like ours, where all the agents of the public must be responsible for their conduct, there can be but few secrets.

Direction: Donkeys stood sleeping in the middle of the street, impervious to car buses and motor bikes weaving around them. It was our first visit to this town after moving to our farm. I remembered my childhood dream of having a donkey for pet, while Ram remembered numerous stories of rabid donkeys biting people in Kenya. “That’s Kenys. There are no rabid donkeys here.” I retorted. “ if they can get rabies in Kenya, so can the ones here,” replied Ram serenely.

Direction: When the rains come, discussing weather stops qualifying as small talk. There are little signs everywhere and even if you usually sit with your bedroom windows tightly shut and your browsers wide open, there is no escaping the monsoon. You didn’t step outside today? No problem. If you scroll down the glowing screen of that laptop you have been staring at for the last three hours, there’ll be enough pictures and status updates to prove that it thundered and showered out in the non-digital world.

Direction: Slums are not caused by the poor but by the government denying people the right to own and exchange property. When people own their own property they have incentives to invest time, money and energy to improve it because they know that they will be able to benefit from any such improvements, i.e., the ability to obtain mortgage etc. In short, property rights beget capital, which begets innovation, which begets wealth. Sadly, the poor typically do not have a secure title to their land as there are bureaucratic restrictions on transferring title or there is no clear system for titling. Without legal deeds they live in constant fear of being evicted by municipal officials or landlords. Illiteracy is a major reason why the poor people often choose not to seek the protection of local courts.

Direction: Since birds don’t have houses where do they store food? In their throat. Yes, birds have a bulge below their throat called the ‘storage bag.’ Food stays there and can be coughed up for chicks to eat. Amazing isn’t it? Not having teeth is not an obstacle for birds. They have a special grinding organ called a Gizzard. Food is crushed by the muscles as it sloshes around the gizzard. Some birds swallow grit and small stones, these stay in the gizzard and help to grind the food.
Q. Where do the birds store food ?
