Hydroelectric plant

Another conventional source of energy is the kinetic energy of flowing water or the state energy of water at a height. In a hydro power plant, the potential energy of the falling water is converted into electrical energy. Which can be used as a source of static energy. Since the number of such water-falls is very low, hydro power plants have been associated with dams. Many dams have been built around the world in the last century. A quarter of our energy demand is supplied by hydro power plants.

High dams are built on the river to collect water in large reservoirs by blocking the flow of water to generate hydroelectricity. The water level rises and in this process the kinetic energy of the flowing water is carried through the energy to the turbine at the bottom of the dam through pipes. Every time the reservoir is replenished with water due to rain (hydroelectricity is a recoverable source) Thus, we do not have to worry about the destruction of hydroelectric sources like fossil fuels that are going to be destroyed one day. But, many difficulties with the construction of large dams

Is involved. Dams can be built in certain areas, especially in hilly areas.

Due to the construction of dams, a lot of arable land and human habitats are destroyed due to submergence, vegetation etc. are submerged in water. The construction of dams also raises problems of satisfactory rehabilitation and compensation of the displaced. Opposition to the construction of the Tehri Dam on the Ganges and the construction of the Sardar Sarovar Dam on the Narmada River was due to similar problems.

SELF DEVELOPMENT

With out a plan nobody can reach their destination. As Bob (2010), described that “Personal development refers to activities that improve self-knowledge and identity, develop talents and potential, build human capital and employability, enhance quality of life and contribute to the realization of dreams and aspirations. The concept is not limited to self-development but includes formal and informal activities for developing others, in roles such as teacher, guide, counsellor, manager, coach, or mentor.

STATUE OF UNITY

Sure, numbers don’t lie but just numbers didn’t really give us an idea about how big the Statue of Unity really is. To understand their true meaning we had to feel them. We knew that the Statue of Unity, standing at 182 metres is now the world’s tallest statue. But not until we stood next to it, dwarfed even by the feet of the Iron Man of India, did we grasp the full enormity of this statue. Statue of Unity, Kevadia, Gujarat, India What is the Statue of Unity? The Statue of Unity is the statue of Sardar Vallabhai Patel. He is popularly referred to as the Iron Man of India. Post India’s independence in 1947, he played a pivotal role in bringing all the then-disjointed princely states into the Union of India. As a tribute to his towering personality, the statue, the tallest statue in the world, is rightly called the Statue of Unity. The enigma of this visit to the Statue of Unity starts with its story. In 2013 kits were sent to nearly 169000 villages of India to collect soil and iro...

HORMONES IN ANIMALS

How are chemicals or stimuli used in animals as a serpent of instruction? Take some animals like squirrels. What does he experience when he is in a hostile situation? He prepares his body to fight or to flee. Both are very complex tasks that require a lot of energy to control. Many different types of different tissues are used and their aggregated (aggregated) functions come together to function. Like fighting or running, two alternating actions are very different from each other. Thus, here is a condition in which some common preparations are beneficial to the body. These preparations ideally facilitate any action in the near future. How can all this happen? If the squirrel's anatomy is based solely on electrical impulses through the neurons, the scope of the tissue ready to perform the next action will be limited. On the other hand, if even a chemical signal could be sent, it could reach all the cells of the body...

O MURDER MOST FOUL

1. “I do not have words to express myself”, I quote Rajnath Singh, speaking in the Lok Sabha, while participating in the debate held yesterday, on the murder in Hyderabad of a young lady. I am afraid I am in the same predicament. The angst and the anguish that I feel are so pronounced and deep seated that it is painful to even breathe. 2. I wonder, if my father would even have begun to imagine that is would be the state of the country, when I was brought into this world? How have we so conveniently forgotten our ‘sanskriti’, our value system that we learnt at the knees of our grandparents and our parents? How have we forgotten that ladies were respected and even venerated in the Vedic times when India was not the India of the present, but a medley of kingdoms within the geographical expanse of the sub-continent? The Veds and the Upanishads are replete with examples of women philosophers, brahmavdinis, teachers and saints. They also clearly indicate the elevated status ...

A STRUGLE OF ARUNIMA SINHA

Arunima Sinha was a national level volleyball player. When she was travelling on a train, some thugs tried to snatch her golden chain. She fought back but was thrown out of the speeding train, and lost her left leg. This happened when she was 24. However this accident never affected her spirit. At All India Institute of Medical Sciences, Delhi an artificial leg was fitted. A year later, she was retrained as a mountaineer and became the first female with an artificial leg to scale Mt. Everest. This is her unforgettable story ofhope, courage and inspiration. Let's read four scenes of her life, narrated in her own words. I had started dozing. My eyes were closed but my mind was awake. I remember someone saying that Bareilly would come after some time. I was in deep thought when I felt a hand tugging at my gold chain. A girl's sixth sense is always her best companion. I instinctively opened my eyes and saw four or five young men around me. Their drunken looks and behaviour gave me...

ATTACK OF DRIVER ANTS

In this clip from the BBC’s Natural World: Ant Attack, we see central and east Africa’s powerful dorylus or driver ants hard at work. Watch as construction and ground workers begin to move up to 80 pounds of soil from the base of a fallen tree. It will become their new home in just a few days. Previous soil residents, beware! Plus, note how their sizes vary greatly, dependant on their role in the colony. A few fascinating facts: Seasonally, when food supplies become short, they leave the hill and form marching columns of up to 50,000,000 ants, which are considered a menace to people, though they can be easily avoided; a column can only ...

CHANDRAYAAN-2

22 જુલાઈ 2019 ચંદ્રયાન 2ની લાંન્ચિંગ થઈ. ભારતનું ચંદ્ર પર જવાનું મિશન ચંદ્રયાન-2 22 જુલાઈ 2019ના બપોરે 2.43 વાગ્યે લૉન્ચ થયું હતું. એક અઠવાડિયા પહેલા તે લાંચ થવાનુ હતુ પણ ટેકનિકલ કારણસર ચંદ્રયાન લૉન્ચ થઈ શક્યું નહોતું. ઈસરોના એક પૂર્વ વૈજ્ઞાનિકે જણાવ્યા અનુસાર, " 9 જુલાઈથી 16 જુલાઈ વચ્ચેનો સમય મિશન લૉન્ચ કરવા માટે આદર્શ હતો." "સોમવારે વૈજ્ઞાનિકો પાસે યાન લૉન્ચ કરવા માટે માત્ર જૂજ મિનિટોની તક હશે, જેમાં અતિશય ચોકસાઈ સાથે કામ કરવું પડશે. આ વખતે મોડું કરવાનો સમય નહીં હોય તેથી જ બધી જ તૈયારીઓ સાથે સજ્જ રહેવું" 16 જુલાઈના રોજ સવારે લૉન્ચ કરવાના બે કલાક પહેલાં વૈજ્ઞાનિકોને હિલિયમની ગૅસ ચૅમ્બરમાં દબાણ ઘટતું જણાતા આ મિશન રોકી દેવાયું હતું. વિલંબ છતાં આ યાન 6 સપ્ટેમ્બરે જ ચંદ્ર પર પહોંચશે, હવે તેનો માર્ગ બદલવામાં આવ્યો છે. ચંદ્રયાન-1 એ ચંદ્રની સપાટી પર પાણીના અવશેષોના પુરાવા આપ્યા હતા, તેથી વિશ્વના વૈજ્ઞાનિકોની નજર ચંદ્રયાન-2 પર છે. ભારતીય અંતરિક્ષ મિશન હેઠળ મીલનો પત્થર માનવામાં આવતા મિશન ચંદ્રયાન-2ની લોંચિંગ થવામાં હજુ બસ થોડાક જ કલાક રહી ગયા હતા. બધી તૈયારીઓ...
