Total economic value (TEV) is a concept in cost–benefit analysis that refers to the value derived by people from a natural resource, a man-made heritage resource or an infrastructure system, compared to not having it. It appears in environmental economics as an aggregation of the (main function based) values provided by a given ecosystem.
The value of an ecosystem can be distinguished as:

Use Value – Can be split into Direct and Indirect use values:

Direct use value: Obtained through a removable product in nature (i.e. timber, fish, water).

Indirect use value: Obtained through a non-removable product in nature (i.e. sunset, waterfall).

Non-use value – Values for existence of the natural resource. For example, knowing that tigers are in the wild, even though you may never see them.

Option value: Placed on the potential future ability to use a resource even though it is not currently used and the likelihood of future use is very low. This reflects the willingness to preserve an option for potential future use.

There are two exceptions to the Law of Demand. Giffen and Veblen goods are exceptions to the Law of Demand. However, they are extreme cases and can be quite difficult to prove. But economists generally agree that there are rare cases where the Law of Demand is violated.

The Law of Demand states that the quantity demanded for a good or service rises as the price falls, ceteris paribus (or with all other things being equal). Therefore, the Law of Demand is an inverse relationship between price and quantity demanded

वास्तव में तो पानी की ही माँग की जाती है। ‘गुड़धानी’ शब्द तो इसके साथ जोड़ दिया गया है। पानी बरसेगा तभी खेतों में ईख और धान उत्पन्न होगा। ईख से गुड बनेगा और गड़धानी तैयार हो पाएगी।

‘गुड़धानी’ का अर्थ पाठ के संदर्भ में अनाज से है। बच्चे मेघों से पानी की माँग भी करते हैं। इसका कारण यह है कि बारिश से प्यास तो बुझती है पर पेट भरने के लिए अनाज की आवश्यकता होती है। अत: वे वर्षा के साथ गुड़धानी (अनाज) की भी माँग करते हैं।

When a medical student is awarded the degree after completing his studies, he has to take an oath that he will always try to save the life of his patients. That is why the medical profession is considered noble and doctors are widely respected. Unfortunately, in the present times, doctors seem to have forgotten their oath.

They look at their patients as a source of income. They subject them to needless expenses by advising unnecessary investigations. Often they conduct surgery which is not needed and make hefty sums of money. Child birth rarely takes place without surgery. Even heart procedures are done without any actual need.

The new description of doctors is that they are ‘greedy’. Their avarice has given rise to such malpractices as tricking patients into surgery and removing their kidneys for sale, *** determination of foetus and illegal abortions. We need to examine the situation seriously. Even though the entire society has become extremely greedy, doctors cannot afford to give up their noble ideals as they deal with human lives.

Andrew had no premonition that that night would influence his future in Blaenelly. That night he saved the life of Mrs Morgan and her baby ; this won him the eternal gratitude of Joe Morgan and L established him firmly in the good books of the villagers.After harsh labour, Mrs Joe Morgan delivered an almost lifeless child. Her own condition was critical. I Andrew had to work fast to save the baby and the mother. He handed the baby to the nurse and turned to the mother.

He gave her some injections and pumped her heart. Then he turned to the baby who had been given up for dead. He saw that the child had suffocated and was unconscious due to lack of oxygen. He tried some unconventional treatment. He immersed the baby alternately in hot and cold water. Then he tried to quicken the baby’s heart. Miraculously the baby responded and started breathing.

Dr. Andrew Mason respected the feelings of the Morgan family. He had gone there to assist Mrs. Morgan in childbirth. It was a difficult task because Mrs. Morgan was going to deliver her first baby after twenty years of marriage. She was no longer young. Therefore, Andrew understood that the baby was very precious to the family. He knew he would have to save both, the mother and the baby for the family’s happiness.

Dr. Andrew soon discovered how tough the task was. Mrs. Morgan started sinking and the child looked as if it was stillborn. He gave the baby to the midwife and concentrated on reviving the mother. When he had secured the mother’s life, he turned to save the child. Working with great dedication and bringing his experience and knowledge to the fore, he was able to revive the child.

After introducing two levels of mathematics papers for class 10 students, CBSE will now offer applied mathematics as an academic elective at the senior secondary level for those who do not want to take it up for higher studies or won't opt for engineering which require a broader understanding of the subject.

The elective subject aimed at developing an understanding of basic mathematical and statistical tools and their applications in the field of commerce and social science, will be offered as elective for class 11students from 2020 academic session and ultimately for class 12 students from the year after.

Students who had taken up basic mathematics in class 10 will be allowed to opt for applied mathematics at senior secondary level.

"Mathematics is widely used in higher studies — in the field of Economics, Commerce, Social Sciences and many others. It has been observed that the existing syllabus of mathematics aligns well with science subjects, but not so much with commerce or social science-based subjects in university education. Keeping this in mind, one more elective course in mathematics syllabus will be offered for senior secondary classes with an aim to provide students relevant experience in mathematics which can be used in the fields other than physical sciences," the Central Board of Secondary Education (CBSE) said in an official notification. According to CBSE officials, a course by this name was earlier designed as a skill subject.

There lies a great difference between text book medicine and the world of practising physician. Text book medicine is purely a Science whereas treating a patient is an art. The world of practising physician requires a different set of skills and knowledge. Text book medicine no doubt provides the conceptual framework for treatment but no doctor can treat a patient without the use of his or her intuitive practices. In the story Birth the way Andrew brings back life in the still born child is a testimony to this fact. The nurse at first dumps the child thinking it to be dead. But Andrews takes a chance and the miracle happens. He in the beginning applies his text book knowledge but the child does not recover. He doesnot lose heart. He applies his own intuitive method and the miracle then happened. Treatment is Science and beyond. It is both a science and an art. The story Birth is a realistic fiction. In other words, the elements of the story has been taken from real life experiences and woven in the fabric of fiction.

Crow needed the pot so that he can fill it with water, and then use that water to wash his beak.

Andrew felt very happy, contented and elated after he had successfully overcome the crisis.   His sincere endeavors to save the lifeless child and his weak mother had proved to be quite successful. He was able to save both the mother and the newly born child. This success had filled him with new energy and vigor. Though he was terribly tired, yet he was content. This saving of two lives filled him with ineffable exhilaration and sense of achievement. He had not felt so much of fulfillment and contentment earlier in his life.

a. Plate tectonics is the theory that states that Earth's outer shell is divided into several plates that glide over the mantle. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere. Plate tectonics is the modern version of continental drift. The plates consist of two principal types of material, oceanic crust, and continental crust. The earth is considered to have 15 major tectonic plates. Seven of which are primary plates and the rest are secondary plates. The primary plates are the African plate, the Antarctic plate, the Eurasian plate, the Indo-Australian plate, the North American plate, the Pacific plate, and the South American plate. The secondary plates are the Arabian plate, the Caribbean plate, the Cocos plate, the Juan de Fuca plate, the Indian plate, the Nazca plate, the Philippine Sea plate and the Scotia plate

According to the Theory of Plate Tectonics, the Earth's crust was initially a single, giant super-continent called Pangea. Its northern part was the Angara land and the southern part was the Gondwana land. The convectional currents split the crust into a number of pieces, thus leading to the drifting of the Indo- Australian plate after being separated from the Gondwana land, towards north. The northward drift resulted in the collision of the plate with the much larger Eurasian Plate.

Due to this collision, the sedimentary rocks which were accumulated in the geosyncline known as theTethys were folded to form the mountain system of western Asia and Himalaya.

How important was this evening’s work in the career of Dr Andrew at Blaenelly?
Answer:
This evening established his name as an efficient doctor because he brought back the baby from the point of death. It won him the goodwill of the villagers.

The room was a mess post the resuscitation of the baby. As Andrew handed the child to the nurse, he felt weak and dazed and around him the room lay in a shuddering litter. Blankets, towels, basins, soiled instruments, hypodermic syringe impaled by its point in the linoleum, the ewer knocked over, the kettle on its side in a puddle of water. The mother was still under the influence of anaesthesia on the huddled bed while the old woman still stood against the wall. Her hands were joined in together and her lips moved inaudibly in prayer.

The unexpected miracle that took place to turn Andrew’s desperation into joy was the newly born lifeless baby began breathing. The baby had been born lifeless; Andrew made his best efforts to revive the baby; his efforts bore fruit and the baby came back to life. This revival of the baby filled him with joy.

Nuclear Energy is the energy in the core of an atom. Where an atom is a tiny particle that constitutes every matter in the universe. Normally, the mass of an atom is concentrated at the centre of the nucleus. Neutrons and Protons are the two subatomic particles that comprehend the nucleus. There ex a st massive amount of energy in bonds that bind atoms together.

Nuclear Energy is discharged by nuclear reactions either by fission or fusion. In nuclear fusion, atoms combine to form a larger atom. In nuclear fission, the division of atoms takes place to form smaller atoms by releasing energy. Nuclear power plants produce energy using nuclear fission. Sun produces energy using mechanism of nuclear fusion.

In the story  Birthby A.J. Cronin, Dr. Andrew had delivered a stillborn baby that had suffered asphyxia, pallida, which is suffocation or unconscious condition caused by lack of oxygen and excess of carbon dioxide in the blood, accompanied by paleness of the skin, weak pulse, and loss of reflexes.

The child was a boy. He was perfectly formed. His limp warm body was white and soft. The cord was hastily slashed. The head lolled on the thin neck. The limbs seemed boneless. His whiteness showed that he suffered from ‘asphyxia pallida’. It meant lack of oxygen in the blood.

The nurse had given up the baby for dead and put it under the bed with sodden newspapers.

• Andrew faced a very difficult situation when his child was born.
• The child was not in good condition as you can say there were no chances of the baby to survive.
• His wife was also not in a good condition as she went through the critical delivery where baby was about to die.
• He got really confused at that time.
• He was in the conflicts between whether he should worry about his child or about his wife.

Andrew was aware of the fact that overwrought as he was he would not be able to snatch even an hour's sleep and this case was particularly demanding. A strange lethargy of spirit was overpowering him. Andrew was reflecting upon the bleakness of life and futility of forming human relationships, he was tired and exhausted from being overworked and felt emotionally drained. His thoughts were heavy and muddled, especially after the episode that he had witnessed at Cardiff station. He thought of the unhappy relationships in which his friends found themselves like Bramwell's foolish devotion to a deceitful woman, Edward Page unhappily bound to a woman and  Denny  living away from his wife. His reason told him that all these marriages were dismal failures and this made him wince. He wished to consider marriage as a state of idyllic happiness, driven by the image of Christine before him. Her eyes shining towards him but he felt conflicted at the thought of the future. His doubting mind and overflowing heart were at odds, making him resentful and confused. There was despondency in his demeanour and he remained in that state so long that all his thoughts became filled up with Christine. He stopped thinking of the issue at hand.

Andrew's thoughts were heavy and muddled because he was thinking of marriage as a failure and sacrifice, how people marry and they separate because of infidelity or other reasons.

Joe Morgan and his wife had been married nearly twenty years and were expecting their first child. At nearly midnight, Joe was worried and walked up and down, waiting for Andrew to reach Bryngower.
