EXPLANATIONS

 

1.

With 46% N content, Urea is the most popular Nitrogenous fertilizer around the world. When Urea is applied to soil, it is first hydrolysed (i.e. broken by water)  into Ammonical form (Ammonium Ion i.e. NH4+) and then to nitrite (NO2-), followed by to nitrate (NO3-) forms by the process called nitrification. Here, we note that most crops use nitrate as source of nitrogen (A few crops such as Paddy prefer Ammonical form over nitrate.). Thus nitrification process is necessary for making nitrogen available to plants. However, if the process of nitrification is too rapid; nitrogen will escape to atmosphere and plants will not be able to recover it from Urea efficiently. Generally, the plants are able to recover a fraction of all Urea N  and this fraction is known as Nitrogen Use Efficiency (NUE). This NUE stands anywhere between 30 to 50%. Thus, two third of Urea Nitrogen escapes from the soil and is not used by the plants. Further, faster conversion of nitrate into Urea also results in accumulation of nitrates in soil / underground water. Once nitrate reaches underground water, it is most difficult to remove; and causes diseases such as blue baby syndrome. This implies that there is a need to regulate the urea hydrolysis and nitrification. This is done by some chemical / natural agents which are called Nitrification inhibitors. However, most of the nitrification inhibitors are costly chemicals (examples nitrapyrin, dicyandiamide and ammonium thiosulphate ) beyond reach of Indian farmers. Coating Urea with Neem oil or Neem cake has been proved to be an effective natural alternative to these chemicals. It has been scientifically established that Neem oil serves as an effective inhibitor if coated on Urea.  Thus, the benefits are as follows: Neem coating leads to more gradual release of urea, helping plants gain more nutrient and resulting in higher yields. Lower underground water contamination due to leaching of urea. Neem serves as a natural insecticide Collection of neem seeds is needed for manufacturing of neem coated urea. This would generate employments in rural areas. Neem-coating will help check heavily subsidized urea’s pilferage to chemical industry and other uses such as making of adulterated milk.

  • The Theosophical Society :
    • Theosophy is the wisdom underlying all religions when they are stripped of accretions and superstitions.
    • The Theosophical Society was founded by Madame Blavatsky and Col. Olcott in 1875 in New York.
    • It was only in 1879, that this ideology gained its roots in Indian culture and society. 
    • It was crystallised in the Madras Presidency with its headquarters in Adayar. 
    • The movement was popularised by Annie Besant in India.
    • Theosophy was based on three principles :
      • Universal brotherhood.
      • The study of comparative religion and philosophy.
      • Investigations into the natural laws which seek to understand the unexplained mystic laws.
    • The Society accepted the Hindu beliefs in reincarnation, Karma and drew inspi­ration from the philosophy of the Upanishads and Samkhya, Yoga, and Vedanta Schools of thought.
    • The movement aimed at the quest of Hindu spiritual wisdom through Western enlightenment.
    • The movement revived and strengthened faith in the ancient doctrines and philosophies of the Hindus.
    • Apart from the philosophical and spiritual discourse, which the Society carried on, its valuable contribution to the Hindu awakening came from its literary and research activities.
      • Hindu scriptures were published and translated.
    • The Society encouraged reforms and framed educational schemes to work them out.

Uranium deposits occur in the Dharwar rocks. Geographically, uranium ores are known to occur in several locations along the Singbhum Copper belt. It is also found in Udaipur, Alwarand Jhunjhunu districts of Rajasthan, Durg district of Chhattisgarh, Bhandara district of Maharashtra andKullu district of Himachal Pradesh.

Thorium is mainly obtained from monazite in the beach sands along the coast of Kerala and Tamil Nadu. World‘s richest monazite deposits occur in Palakkad and Kollam districts of Kerala, near Vishakhapatnam in Andhra Pradesh and Mahanadi river delta in Odisha.

The Red blood cells have a strong affinity for carbon monoxide and in the presence of carbon monoxide, they do not rapidly bind with oxygen. This reduces the transport and delivery of oxygen to the organs. It also reduces the transport of carbon dioxide but the harm is mainly caused by ineffective oxygen supply. It does not cause any damage to Red blood cells and cannot increase the transport of carbon dioxide.

5.

The Equator receives less insolation than the tropics because of the presence of clouds. At the same latitudes the insolation is more over the continent than oceans because clouds over the ocean reflect back the sunlight.

Insolation over continents and oceans at the same latitude

Insolation refers to the amount of solar radiation that reaches a specific area. It plays a significant role in determining the climate and weather patterns of a region. In this context, we are comparing the insolation over continents and oceans at the same latitude.

1. Oceans are cloudier:

- Oceans have a higher potential to be cloudier compared to continents. This is because water bodies have higher evaporation rates, leading to increased moisture content in the atmosphere.

- The presence of clouds can significantly affect the amount of solar radiation reaching the surface. Clouds can reflect or absorb solar radiation, reducing the amount that reaches the surface.

- Therefore, due to the higher likelihood of cloud cover over oceans, the insolation is generally lower compared to continents at the same latitude.

2. Continents have varied relief:

- Continents are characterized by varied relief features such as mountains, plateaus, and plains. These relief features can influence the distribution of solar radiation.

- Mountains, for example, can intercept the path of incoming solar radiation, causing shadows and reducing the amount of insolation reaching the surface. This phenomenon is known as the orographic effect.

- In contrast, plains and low-lying areas tend to receive more direct solar radiation as there are no significant barriers to block or divert the incoming solar radiation.

- Therefore, the varied relief of continents can lead to differences in the distribution of insolation at the same latitude compared to oceans.

· The 89th Constitutional Amendment Act of 2003, bifurcated the combined National Commission for Scheduled Castes (SCs) and Scheduled Tribes (STs) into two separate bodies, namely, the National Commission for Scheduled Castes (under Article 338) and the National Commission for Scheduled Tribes (under Article 338-A).

· The separate National Commission for Scheduled Castes came into existence in 2004. It consists of a Chairperson, a Vice-Chairperson and three other members. They are appointed by the President, by warrant under his hand and seal. Their conditions of service and tenure of office are also determined by the President.

· The Commission is vested with the power to regulate its own procedure.

· The Commission, while investigating any matter or inquiring into any complaint, has all the powers of a civil court.

The following matters are kept outside the functional jurisdiction of the UPSC. In other words, the UPSC is not consulted on the following matters:

·      While making reservations of appointments or posts in favor of any backward class of citizens.

·      While taking into consideration the claims of scheduled castes and scheduled tribes in making appointments to services and posts.

·      With regard to the selections for chairmanship or membership of commissions or tribunals, posts of the highest diplomatic nature and a bulk of group C and group D services.

·      With regard to the selection for temporary or officiating appointment to a post if the person appointed is not likely to hold the post for more than a year.

UPSC assists the states (if requested by two or more states to do so) in framing and operating schemes of joint recruitment for any services for which candidates possessing special qualifications are required.

  • The Isotherm Line,  which divides the India North-South into almost two equal parts in January is 20°C. 
    • Isotherms are the lines that connect points of equal temperature on weather maps, so at every point along a given isotherm, the temperature values are the same.
    • Isotherms help to visualize and to interpret the horizontal temperature distribution of an area by showing the patterns of temperature on a weather or oceanography map.
  • Constructing the map of isotherms is an elementary step in the temperature data analysis, and the process, in general, is known as contouring.
  • It can even be done for other parameters like barometric pressure (isobars), dew point temperature (isodrosotherms), geopotential height (isohypses), wind speed (isotachs), and salinity (isohalines). Isotherms are always smooth, labeled with the values, and mostly parallel to each other. 
  • The isotherm of 20°C runs roughly parallel to the Tropic of Cancer.

The ongoing extinction of the Earth''s flora and fauna due to human activities is termed as holocene extinction.

The main difference between the “Sixth Extinction” and the previous five extinctions is that the sixth extinction occurs faster. While all extinctions throughout Earth’s history have had varying causes and impacts, the current sixth extinction event, also known as the Holocene Extinction or Anthropocene Extinction, is characterized by its accelerated pace. This extinction event is primarily driven by human activities, such as habitat destruction, climate change, pollution, overexploitation of natural resources, and the introduction of invasive species. It is affecting a wide range of organisms, including both plants and animals, across various ecosystems worldwide. While island ecosystems can be particularly vulnerable to extinction, the sixth extinction is not solely limited to islands but is a global phenomenon.

Azolla forms a symbiotic relationship with the nitrogen-fixing cyanobacterium Anabaena. The small aquatic fern is its home, providing shelter and nutrients in specialized structures known as root pockets. This connection is advantageous to both parties – Azolla obtains fixed nitrogen from Anabaena, while the cyanobacterium gains a safe environment and nutrient supply within the root pockets of the fern.

The straits namely the Sunda and the Lombok are in the Indian Ocean. Sunda lies between the Indonesian islands of Java and Sumatra and links the Java Sea with the Indian Ocean. The strait is shallow and narrow, has heavy tidal waves, drilling platforms and tiny islands, all of which do not make it attractive for movement of large oil tankers. Lombok lies between the islands of Bali and Lombok, and is a possible alternative route to the Malacca Strait, but using it adds 1,600 km and over three days to journey time.

India was under Review of Significant Trade process for Red Sanders since 2004.

The removal of Red Sanders from RST process from India was unconditional.

The CITES Standing Committee has now decided to place India in Category 1 from Category 2.

https://pib.gov.in/PressReleasePage.aspx?PRID=1976624#:~:text=The%20Minister%20said%20India%20was,farmers%20who%20grow%20Red%20Sanders.

Red Sanders

Red sanders, classified as endangered by the IUCN, CITES (Appendix II), and Wildlife Protection Act (Schedule IV), are native to a specific region within the Eastern Ghats and are known for their unique flora. It is referred to as ‘the pride of Eastern Ghats’. These trees have a slow growth rate, taking 25 to 40 years to mature, and they display remarkable resistance to droughts.

The Red Sanders heartwood is valued for its wavy grain. Besides its use in furniture, the red dye (called ‘santalin’) extracted from the wood serves as a colouring agent for textiles, medicine, and food.

CITES

· CITES is an international agreement aimed to ensure that international trade in specimens of wild animals and plants does not threaten the survival of the species.

· Currently there are 184 Parties to CITES.

· It entered into force in 1975 and India became the 25th party, a state that voluntarily agrees to be bound by the Convention, in 1976.

· Although CITES is legally binding on States it is generally not self-executing.

· This means that it cannot be fully implemented until specific domestic measures have been adopted for that purpose.

· It is therefore essential that CITES Parties have legislation in place allowing them to implement and enforce all aspects of the Convention.

CITES National Legislation Programme:

· National laws must fulfill all these minimum requirements under CITES National Legislation programme:

· Designate a Management Authority and a Scientific Authority.

· Prohibit trade violating the Convention.

· Penalize such illicit trade.

· Confiscate illegally traded or possessed specimens.

After consulting the concerned Party, the CITES Secretariat assesses the national legislation concerning these criteria and categorizes it into one of three categories:

· Category 1: Legislation generally meeting CITES implementation requirements.

· Category 2: Legislation generally not meeting all CITES implementation requirements.

· Category 3: Legislation generally not meeting CITES implementation requirements.

The first newspaper to be printed in both the Indian subcontinent and Asia was the weekly newspaper Bengal Gazette started by James Augustus Hicky. The paper was published for two years, I.e., between 1780 and 1782, before the East India Company seized the newspaper''s types and printing press. Because he was a strong critic of Governor General Warren Hastings'' administration.

Hickey began publication for the newspaper on 29 January 1780 after printing a prospectus announcing the fact that he will print newspapers. One must realise that the idea of printing a newspaper in India had been floating around for more than 12 years before Hickey took it upon him to execute the idea of printing.

Hicky''s Bengal Gazette was known for its sarcastic and provocative writing style. Unlike many newspapers of its time, the newspaper discussed taboo topics proto-class consciousness, arguing for the rights of the poor and the right to taxation with representation

·      One of the important events during the tenure of Lord Hastings was abolition of Censorship. This was basically because of his dislike towards “unnecessary” imposition of restrictions on Press. But as a precaution, he issued some guidelines prohibiting company’s policies in the newspapers.

·      The result was that many fresh newspapers came up. India’s first Vernacular newspapers Samachar Darpan was started in 1818. However, some scholars note that “Bengal Gazetti” was published even prior to this Vernacular magazine by Ganga Kishore Bhattacharya.

·      Then in 1818 only “Calcutta Journal” was started by J S Buckingham.

·      3 years later Raja Ram Mohun Roy started national press in India. He published “Sambad Kaumudi” in 1821. This was one of the pre-reformist publications that had actively campaigned for “Abolition of Sati“.

·      There was a growing public outcry for Sati and it “inspired” Lord William Bentinck to abolish “Practice of Sati” in 1829.

·      However, this liberal policy of Lord Hastings could not continue further. The successors of Lord Hastings took harsh actions against the press people.

The term Nadukal mentioned in the Sangam literature means memorial stone.

Manulanar was a Brahmin caste member. Mamulanar has written about the Ganges'' destruction of the Pataliputra. Manulanar was a poet of the Sangam age who has referred to a Mauryan expedition against a Tamil chieftain The fire of Patalipura in the first century CE, on the other hand, was not mentioned. Mamulanar lived no later than the 1st century BCE, according to these findings. Some have concluded that the Podiyil hill, which adjoins the Tirunelveli and Madurai districts (Tamil Nadu) to the west, was the farthest limit of the Mauryan invasion in the south, based on references to Mauryas in Sangam literature (in five Sangam poems, three by Mamulanar).

With this edict, Akbar’s judgment was set above every legal and religious authority, so it was the promulgation of the doctrine of Imperial infallibility.

Gol Gumbaz: Bijapur (modern Vijayapura) was the capital of the Adil Shahi dynasty during1480-1686. It is famous for its magnificent buildings and dargahs. Gol Gumbaz (round dome) is the mausoleum of the seventh ruler of the dynasty Mohammad Adil Shah (1627-1656). Mohammad Adi Shah commissioned the mausoleum in his lifetime. Built of dark grey basalt and decorated plaster, the exterior of Gol Gumbaz is simple but beautiful. On the four corners of the bare walls are four doomed octagonal towers. Each tower has seven storeys and each storey has several windows which give the structure a striking look. The dome is the second largest in the world after St. Peter’s Basilica in Rome. The huge chamber of 135 ft each wall and 178 ft high contain an elevated platform on which five cenotaphs are placed. Those are of Muhammad Adil Shah, his wife Arus Bibi, a daughter, a grandson and his favourite mistress Rambha.

The structure is known for its acoustics, as a whisper on one side of the dome can be heard clearly on the other side, over 100 feet away.

·        Gol Gumbaz is situated in Bijapur, Karnataka.

·        Gol Gumbaz built by Mohammad Adil Shah is the largest masonry dome in the world.

Methane is a colorless, odorless gas that’s produced both by nature (such as in wetlands when plants decompose underwater) and in industry (for example, natural gas is mostly made of methane). It is widely regarded as the second most important greenhouse gas, after carbon dioxide (CO2). However, methane is about 200 times less abundant in the atmosphere and lasts there for only about a decade on average—while CO2 can last for centuries. To put it another way: methane does its damage quickly but soon fades away, while CO2 traps a smaller amount of heat consistently, decade after decade.

Termites eat wood and produce methane as a result of the breakdown of cellulose in their digestive tracts. They are thought to be responsible for 11% of the methane in the atmosphere (some estimates are as high as 20% - 40%). The clearing of the rain forests greatly impacts termite populations and in turn the methane content of the atmosphere. When a patch of rain forest is cleared, termite populations explode due to the ample food source that is left behind. Water vapor can vary from 4% in the steamy tropics to nearly nonexistent in the cold dry regions of the Antarctic. Water vapor is a good absorber of Earth''s outgoing radiation and thus is considered a greenhouse gas. When water vapor is converted to a liquid during condensation, clouds are formed.

Radio Transmission is possible due to Ionosphere.

The thickness of the ozone layer generally varies with the seasons and other geographical factors. According to reports, the ozone layer is approximately 20 to 30 kilometres above Earth, which is about 3 mm in thickness or about 300 Dobson Units. Every year, 16th of September is observed as the World Ozone Day. The ozone layer plays a very significant role both by protecting the planet earth and the lives existing on it. Therefore, we all should protect the ozone layer by limiting the use of CFCs – Chlorofluorocarbons, Chlorine, pesticides, nitrous oxide, halo-carbons and other harmful gases and help in the restoration of the Ozone layer.

Negative effects of thickening of Ozone layer

·  Climate change: Ozone is a greenhouse gas, and a thicker ozone layer could contribute to warming of the Earth''s atmosphere. This could potentially exacerbate climate change and its associated impacts, such as rising global temperatures and changing weather patterns.

·  Interference with atmospheric processes: Changes in the ozone layer thickness could disrupt atmospheric processes, such as the formation of weather patterns and the circulation of air masses. This could have unpredictable effects on regional and global climate systems.

Food preservatives prevent spoilage of food due to microbial growth. The most commonly used preservatives include table salt, sugar, vegetable oils and sodium benzoate, C6H5COONa. Sodium benzoate is used in limited quantities and is metabolised in the body. Salts of sorbic acid and propanoic acid are also used as preservatives.

·        The most common chemicals used to inhibit the growth of microorganisms are salts and edible oils. As a result, they are referred to as preservatives.

·        To prevent microbes from attacking pickles, we add salt or acid preservatives.

·        These are also used to prevent spoilage in jams and squashes. 

·        Common preservatives include sodium benzoate and sodium metabisulphite. 

·        Sodium benzoate is used as a food preservative because of its anti-fungal properties. This chemical compound enters each cell and balances the pH of the food, effectively increasing the acidity of the food and assisting in food preservation.

·        Many pharmaceutical formulations contain sodium metabisulphite as an antioxidant. It is widely used as a preservative and disinfectant in food.

The ordinance-making power is the most important legislative power of the President. It has been vested in him to deal with unforeseen or urgent matters. But, the exercise of this power is subject to the following four limitations: 

· He can promulgate an ordinance only when both the Houses of Parliament are not in session or when either of the two Houses of Parliament is not in session. An ordinance can also be issued when only one House is in session because a law can be passed by both the Houses and not by one House alone. 

· He can make an ordinance only when he is satisfied that the circumstances exist that render it necessary for him to take immediate action. In Cooper case, (1970), the Supreme Court held that the President‟s satisfaction can be questioned in a court on the ground of malafide. This means that the decision of the President to issue an ordinance can be questioned in a court on the ground that the President has prorogued one House or both Houses of Parliament deliberately with a view to promulgate an ordinance on a controversial subject, so as to bypass the parliamentary decision and thereby circumventing the authority of the Parliament. 

· His ordinance-making power is coextensive as regards all matters except duration, with the law-making powers of the Parliament. 

· Every ordinance issued by the President during the recess of Parliament must be laid before both the Houses of Parliament when it reassembles.

It was a result of both the major religious groups of farmers in Bengal, notably a farmer Haji Molla of Nischindipur said that he would rather beg than sow indigo. The farmers were in no possession of any type of arms and had no proper organization and discipline. Hem Chandra Kar was one of the prominent leaders of the rebellious ryots.

The key objective of the Indigo Revolt of 1859-60 was to stop the forced cultivation of indigo by European planters, who oppressed the peasants. The Revolt was a success because by 1860, most of the indigo factories were shut down and the ryots won the freedom to sow the crop of their choice in their fields.

Hindu-Muslim-Christian unity – Hindus and Muslims fought shoulder – to shoulder, whereas missionaries extended active support to the ryots.

Sashanka, the Gauda ruler, believed to have ruled between 590 and 625 CE, is considered the first prominent king of ancient Bengal. After the fall of the Gauda kingdom, there was no central authority, which led to recurring wars between petty chieftains. So, in 750 CE, a group of chiefs met and decided on a “Kshatriya chief ” named Gopala to be their ruler. There is a story that Gopala was elected because of his ability to kill a “demoness” that had killed those who were previously elected like him. Though Gopala did not have royal antecedents, he succeeded in acquiring a kingdom. Gopala’s political authority was soon recognised by several independent chiefs. His original kingdom was in Vanga or East Bengal.

Pala Rulers

Gopala I was succeeded by his son Dharmapala (770–815 CE) who made the Pala kingdom a force to reckon with. Bengal and Bihar were directly ruled by him. Kanauj was ruled by his nominee. The rulers of the Punjab, Rajaputana, Malwa and Berar accepted his suzerainty. He assumed titles like Paramesvara, Parambhattaraka and Maharajadhiraja.

Dharmapala proved to be a great patron of Buddhism. He founded the Vikaramasila monastery in Bhagalpur district in Bihar, which developed into a great centre of Buddhist learning and culture. He built a grand vihara at Somapura in modern Paharapura (present-day Bangladesh). Dharmapala also built a monastery at Odantapuri in Bihar. He patronised Harisbhadra, a Buddhist writer.

Dharmapala’s son Devapala extended Pala control eastwards up to Kamarupa (Assam). He defeated Amoghavarsha, the Rashtrakuta ruler, by allying with all the states that regarded the Rashtrakutas as their common enemy. Devapala was also a great patron of Buddhism. He granted five villages to Balaputradeva, the king of the Sailendra dynasty of Suvarnadipa (Sumatra), to maintain a monastery built by him at Nalanda. Nalanda continued to flourish as the chief seat of Buddhist learning even during the Pala reign.

Devapala was succeeded by Vigramapala, who abdicated his throne after ruling for a few years and went to lead an ascetic life. Narayanapala, son of Vigramapala, was also a man of pacific and religious disposition. The Rashtrakutas and the Pratiharas took advantage of Narayanapala’s disposition and defeated the Palas. The rise of the Pratiharas in Jalore under Mihira Bhoja and the advance of the Rashtrakutas into Pala territories inevitably brought about the decline of the Palas. The petty chiefs, who formerly owed allegiance to the Palas, also started asserting their independence.

The slide of the Pala dynasty was accelerated during the rule of his three successors – Rajyapala, Gopala III and Vigramapala II. The fortunes of the dynasty, however, were revived by Mahipala I, son of Vigramapala II. The most important event of his period was the invasion of northern India by Rajendra Chola sometime between 1020 and 1025 CE. However, the advance of the Cholas beyond the Ganges was checked by Mahipala I.

After 15 years of Mahipala’s rule, four insignificant rulers followed. Ramapala was the last ruler who tried to recover the lost glory of the dynasty. He ruled for about 53 years and after his death, the presence of Pala dynasty was confined to only a portion of Magadha (Bihar) and continued to exist only for a short period. Vijayasena of the Sena dynasty who had become powerful by then in northern Bengal expelled the last ruler Madanapala (1130–1150 CE) from Bengal and established his dynastic rule.

Religion - The Palas were great patrons of Mahayana Buddhism. The Buddhist philosopher Haribhadra was the spiritual preceptor of Dharmapala, the founder of the Pala kingdom. Bengal remained one of the few places where Buddhist monasteries continued to exist. The kingdom as well as Buddhism soon suffered decline because of large-scale conversion of merchants and artisans to Islam.

Art and Architecture - Two artists of this period were Dhiman and his son Vitapala. They were great painters, sculptors and bronze statue makers. The Pala school of sculptural art was influenced by the Gupta art. Mahipala I constructed and repaired several sacred structures at Saranath, Nalanda and Bodh Gaya. Gopala founded the famous monastery at Odantapura (Bihar). Dharmapala established the Vikramashila and the Somapura Mahaviharas (Bangladesh).

Literature - The prominent Buddhist scholars of Vikramashila and Nalanda universities were Atisha, Saraha, Tilopa, Dansheel, Dansree, Jinamitra, Muktimitra, Padmanava, Virachan and Silabhadra. The notable Pala texts on philosophy include Agama Shastra by Gaudapada, and Nyaya Kundali by Sridhar Bhatta. Many texts on medicine were compiled by Chakrapani Datta, Sureshwar Gadadhara Vaidya and Jimutavahana. The Palas also patronised Sanskrit scholars. Many Buddhist tantric works were authored and translated into Sanskrit. The original tantric works comprise a varied group of Indian and Tibetan texts. The “Mahipalageet” (songs on Mahipala), a set of folk songs, are still popular in the rural areas of Bengal. Sandhyakar Nandi’s epic Ramacharitam, a biography of a later Pala ruler Ramapala, describes how forest chiefs were brought into their alliance through lavish gifts.

Unlike crude oil and crude-derived liquid fuels, LNG spills do not require any remediation of soil, groundwater or surface waters because it evaporates immediately and dissipates quickly into the atmosphere.

Petroleum / Mineral oil

Natural Gas

  1. Found in sedimentary rocks of marine origin
  2. Formed by decomposition of tiny marine creatures, plants & vegetation under mud, silt & sand. Over the years, it undergoes chemical changes to form crude oil & natural gas under the action of heat & pressure.
  3. 20 % of India’s crude oil & gas demand is produced domestically & 80 % is imported from (UAE, Saudi, Iran, Russia).
  4. Jamnagar Refineries of Reliance industries is world largest refinery complex.
  5. HPCL is a Navratna company. It has 2 refineries - Mumbai and Vishakhapatnam.
  1. NG is odorless, colorless gas made of variety of compounds but methane is the most imp. It is found in association with mineral oil (75% is in Bombay High and Bassein).
  2. NG gas 70-90% Methane, Ethane, Propane and Butane (0-20% combined), CO2, Oxygen, Nitrogen, H2S and Trace gases like (A, He, Ne, Xe).
  3. 40% Goes to Chemical fertilizers, 30% (Power generation) and 10% LPG.

Compressed Natural Gas

Liquified Natural Gas

  • CNG is obtained by compressing NG under high pressureReduces its volume.
  • Advantages
    • Viable alternative fuel (Storage cylinders)
    • Cheaper and reduce emissions.
    • Versatile and low storage costs.
    • Cleaner solution from diesel
  • Disadvantages
    • Explosion ka risk.
    • Infra support needed.
  • Applications: Buses, Trucks.
  • >90% is Methane and 3-4% is Ethane.
  • CNG is also very light, so if there is a leak, it will dissipate rapidly into air but LPG will settle on ground. This makes CNG a safer choice over LNG. CNG releases less GHGs.

Hydrogen Enriched Compressed Natural Gas (H-CNG)

  • The blending of hydrogen with CNG provides a blended gas termed as HCNG. HCNG combines the advantages of both hydrogen and methane.
  • Delhi - the first city in the country to roll out HCNG buses for public transport from November 2020.

This is a step towards combating air pollution.

  • LNG is produced by cooling NG to - 162 degree C in Cryogenic stage through LiquifactionKept in liquid form to increase quantities of NG that can be stored in tanks.
  • Advantages
    1. Easy to transport.
    2. Helps in electrification.
    3. Clean burning fuel, smoke free, less CO2 than Coal, no black carbon.
  • Disadvantages: Explosion and Infra.
  • Application: Business, Industry, Power generation, Cooking.
  • LNG takes less storage space than CNG.

LPG

is a byproduct derived while extracting crude petroleum. It has Propane and Butane. It produces CO2, NOx and CO and is much cleaner than Gasoline. Heavier than air hence it will settle down on leakage.

Coming together federation

Holding together federation

In this type of federation, separate sovereign states connect together to become a greater government.

In this type of federation, a broad force or country agrees to split its powers between the constituent states and the central government.

Individual States combine their sovereign rights and assets to form a stronger nation.

There is no pooling of authority and retention of nationality in such a federation.

In this federation, the individual states have sole authority. The ultimate result is a more stable nation.

In this federation, the central government has more authority than the states.

Examples are the USA, Australia, Switzerland

Examples are India, Spain, Belgium
