Tidal air

The term "tidal air" refers to the air that moves in and out of the lungs with each breath in a normal restive mode. It is the air that is involved in the normal breathing process, where the lungs expand during inhalation and contract during exhalation.

Characteristics of Tidal Air
- Tidal air is the air that is exchanged during normal, quiet breathing.
- It represents the volume of air involved in the respiratory cycle under resting conditions.
- Tidal air does not include the residual volume of air that remains in the lungs after maximum exhalation.

Importance of Tidal Air
- Tidal air plays a crucial role in providing the body with oxygen and removing carbon dioxide, which are essential for cellular respiration.
- It helps maintain the balance of gases in the blood, ensuring proper oxygenation of tissues and organs.

Measurement of Tidal Air
- Tidal air can be measured using a spirometer, a device that records the volume of air inspired and expired by the lungs.
- The tidal volume is typically around 500 mL in healthy adults during normal breathing.

In conclusion, tidal air is the term used to describe the air that moves in and out of the lungs during normal breathing. It is an essential component of the respiratory cycle, ensuring that the body receives an adequate supply of oxygen and removes waste carbon dioxide.

Direction: Read the case study given below and answer the questions that follow:Ralegan Siddhi is a small village in the district of Ahmednagar, Maharashtra. It has become an example for watershed development throughout the country.In 1975, this village was caught in a web of poverty and illicit liquor trade. The transformation took place when a retired army personnel, settled down in the village and took up the task of watered development. He convinced villagers about the importance of family planning and voluntary labour; preventing open grazing, felling trees, and liquor prohibition.Voluntary labour was necessary to ensure minimum dependence on the government for financial aids. “It socialised the costs of the projects”, explained the activist. Even those who were working outside the village contributed to the development by committing a month’s salary every year. Work began with the percolation tank constructed in the village. In 1975, the tank could not hold water. The embankment wall leaked. People voluntarily repaired the embankment. The seven wells below it swelled with water in summer for the first time in the living memory of the people. The people reposed their faith in him and his visions.A youth group called Tarun Mandal was formed. The group worked to ban the dowry system, caste discrimination and untouchability. Liquor distilling units were removed and prohibition imposed. Open grazing was completely banned with a new emphasis on stall-feeding. The cultivation of water intensive crops like sugarcane was banned. Crops such as pulses, oil seeds and certain cash crops with low water requirements were encouraged. All elections to local bodies began to be held on the basis of consensus. “It made the community leaders complete representatives of the people.” A system of Nyay Panchayats (informal courts) were also set up. Since then, no case has been referred to the police. A Rs. 22 lakh school building was constructed using only the resources of the village. No donations were taken. Money, if needed, was borrowed and paid back. The villagers took pride in this self-reliance. A new system of sharing labour grew out of this infusion of pride and voluntary spirit. People volunteered to help each other in agricultural operation. Landless labourers also gained employment. Today the village plans to buy land for them in adjoining villages. At present, water is adequate; agriculture is flourishing, though the use of fertilizers and pesticides is very high. The prosperity also brings the question of ability of the present generation to carry on the work after the leader of the movement who declared that, “The process of Ralegan’s evolution to an ideal village will not stop. With changing times, people tend to evolve new ways. In future, Ralegan might present a different model to the country.”The term Nyaya Panchayats refers to

Read the following case and answer the questions that follows:International Organizations (IOs) are formal institutional structures transcending national boundaries which are created by multilateral agreement among nation-states. Their purpose is to foster international cooperation in areas such as: security, law, economic, social matters and diplomacy. IOs are subdivided between Intergovernmental Organizations (IGOs) and Non-Governmental Organizations (NGOs); Intergovernmental Organizations are entities created with sufficient organizational structure and autonomy to provide formal, ongoing, multilateral processes of decision making between states, along with the capacity to execute the collective of their member (states). NGOs are non-state voluntary organizations formed by individuals to achieve a common purpose, often oriented beyond themselves or to the public good. The development and expansion of these large representative bodies date back to the end of the World War II, where there was a need for world reconstruction through International Relations. Since then, there has been an incremental rise of organizations that work on different socio-political and economic aspects with various and specific aims in approaching states, societies, groups and individuals. Based on these key definitions, it is an attempt to explain how important are IOs and the extent to which they have an impact on global politics and international relations through an analysis of two main IR scholar theories namely Realism and Liberalism. Moreover, to understand the impact of IOs, these theories will be explored and analysed through contexts of different and conflicting realist and liberalists thinkers upon their view on these institutional structures. It will also distinguish and compare the two theories and determine which is more relevant to the contemporary world international relations.Q. Where can we find the development and expansion of these organisations?

Read the following passage carefully and answer the questions that follow:In the broadest sense of the term, development conveys the ideas of improvement, progress, well-being and an aspiration for a better life. Through its notion of development, a society articulates what constitutes its vision for the society as a whole and how best to achieve it. However, the term development is also often used in a narrower sense to refer to more limited goals such as increasing the rate of economic growth, or modernising the society. Development has unfortunately often come to be identified with achieving pre-set targets, or completing projects like dams, or factories, hospitals, rather than with realising the broader vision of development which the society upholds. In the process, some sections of society may have benefited while others may have had to suffer loss of their homes, or lands, or way of life, without any compensatory gains.Q. When is the term 'development' used in the narrower sense?
