Plot

  • The Village by the Sea is set in a small village called Thul in Western India(14 kilometres from bombay) and focuses on a family trying to make ends meet. The main protagonists are Lila, the eldest child who is 13 years old, and her 12-year-old brother Hari.
    They also have two younger sisters, Bela and Kamal. They live with their mother, who has been chronically ill and is bed-ridden. Their father is an alcoholic, which forces Hari and Lila to manage the family (as surrogate parents). There is much stress on them due to the constant demand of meeting the need of money. Although their father was earning money, he used to spend it to buy alcoholic materials.
    With two younger sisters to take care of, life for Lila and Hari is too hard. Hari decides that he has had enough and leaves for Bombay to find work. Lila is left alone to take care of her family, and struggles to do so. Help comes from an unexpected source, the rich De Silvas who have a bunglow or summerhouse- Mon Repos next to their hut.
    Meanwhile, Hari is new in the great city of Bombay and all alone. A kind restaurant proprietor, Jagu, takes pity on him and welcomes him to work in his restaurant. There, Hari builds a strong friendship with Mr. Panwallah, the lovable watch repairer whose shop is just beside Jagu’s. Through his experience with Mr. Panwallah and Jagu and the chain of events that take place in Bombay, Hari realizes that he could actually make a career as a watchmaker.
    Meanwhile, Lila, Bela and Kamal admit their sick mother in town hospital through the help of the De Silvas. Their father turns over a new leaf, and accompanies their mother throughout her 7-month treatment. When Hari returns to the village soon-after, he finds the environment of his home totally changed. As Hari reunites with his sisters, they all begin sharing stories with each other detailing the changes that took place after Hari left. Hari also explains the watch repair skills he learned in Bombay and reveals his plans to start a small repair shop in the village. Together; Lila, Hari, Bela, and Kamal all form a plan to use Hari's saved money (which he made and brought back from Bombay) to start a small chicken farm as a start up business for the family and financial support base for Hari's future repair shop. As Hari goes to the village to buy chicken netting fence and tools to build a chicken pen, a traveler converses with him and marvels at Hari upon learning his plans. As the novel ends, the traveler highlights Hari and his sister's resolve to adapt and change in a growing and ever developing world.
    Anita Desai has explicitly described in her very own style of writing,and she shows how Hari in the dilapidated conditions of the Sri Krishna Eating House finds warmth and affection through Mr Panwallah-owner and watch mender of the Ding-Dong watch shop. Mr Panwallah instills confidence in Hari and comforts him when he is terribly home sick. He even gives Hari a vivid and inspiring future and teaches him watch mending. This shows that even in one of the busiest, rickety and ramshackle cities such as Bombay there is still hope, love and affection He also goes back to Thul with the help of Mr panwallah and Jagu insisting to buy the bus ticket. Jagu's generosity by giving him some extra money to be brought back to his family.

Jane Eyre

                                         Jane Eyre

                                                      Jane Eyre title page.jpg
  • Introduction
    Jane Eyre is a first-person narrative of the title character. The novel goes through five distinct stages: Jane's childhood at Gateshead, where she is emotionally and physically abused by her aunt and cousins; her education at Lowood School, where she acquires friends and role models but also suffers privations and oppression; her time as the governess of Thornfield Hall, where she falls in love with her Byronic employer, Edward Rochester; her time with the Rivers family, during which her earnest but cold clergyman cousin, St John Rivers, proposes to her; and the finale with her reunion with, and marriage to, her beloved Rochester. During these sections the novel provides perspectives on a number of important social issues and ideas, many of which are critical of the status quo (see the Themes section below). Literary critic Jerome Beaty notes that the close first person perspective leaves the reader "too uncritically accepting of her worldview" and often leads reading and conversation about the novel towards supporting Jane, irregardless of how irregular her ideas or perspectives.[5]
    Jane Eyre is divided into 38 chapters and most editions are at least 400 pages long. The original publication was in three volumes, comprising chapters 1 to 15, 16 to 26, and 27 to 38; this was a common publishing format during the 19th century (see three-volume novel).
    Brontë dedicated the novel's second edition to William Makepeace Thackeray.

    [edit]Jane's Childhood

    Young Jane argues with her guardian Mrs. Reed of Gateshead. Illustration by F. H. Townsend.
    The novel begins with the titular character Jane Eyre living with her maternal uncle's family, the Reeds, as her uncle's dying wish. The novel starts when Jane is ten years old and several years after her parents died of typhus. Mr. Reed was the only one in the Reed family to be kind to Jane. Jane’s aunt Sarah Reed does not like her, treats her worse than a servant and discourages and, at times, forbids her children from associating with Jane. Mrs. Reed and her three children are abusive to Jane, both physically and emotionally. The servant Bessie proves to be Jane's only ally in the household even though Bessie sometimes harshly scolds Jane. Excluded from the family activities, Jane is incredibly unhappy with only a doll to find solace. One day, Jane is locked in the red room, where her uncle died, and panics after seeing visions of him. She is finally rescued when she is allowed to attend Lowood School for Girls, after the physician Mr. Lloyd convinces Mrs. Reed to send Jane away. Before Jane leaves, she confronts Mrs. Reed and declares that she'll never call her "aunt" again, that Mrs. Reed and her daughters, Georgiana, and Eliza are deceitful and that she'd tell everyone at Lowood how cruelly Mrs. Reed treated her.

    [edit]Lowood

    Jane arrives at Lowood Institution, a charity school, the head of which (Brocklehurst) has been told that she is deceitful. During an inspection, Jane accidentally breaks her slate, and Mr. Brocklehurst, the self-righteous clergyman who runs the school, brands her a liar and shames her before the entire assembly. Jane is comforted by her friend, Helen Burns. Miss Temple, a caring teacher, facilitates Jane's self-defense and writes to Mr. Lloyd, whose reply agrees with Jane's. Ultimately, Jane is publicly cleared of Mr. Brocklehurst's accusations.
    The eighty pupils at Lowood are subjected to cold rooms, poor meals, and thin clothing. Many students fall ill when a typhus epidemic strikes. Jane's friend Helen dies of consumption in her arms. When Mr. Brocklehurst's neglect and dishonesty are discovered, several benefactors erect a new building and conditions at the school improve dramatically.

    [edit]Thornfield Hall

    After six years as a student and two as a teacher, Jane decides to leave Lowood, like her friend and confidante Miss Temple. She advertises her services as a governess, and receives one reply. It is from Alice Fairfax, the housekeeper at Thornfield Hall. She takes the position, teaching Adele Varens, a young French girl. While Jane is walking one night to a nearby town, a horseman passes her. The horse slips on ice and throws the rider. She helps him to the horse. Later, back at the mansion she learns that this man is Edward Rochester, master of the house. He teases her, asking whether she bewitched his horse to make him fall. Adele is his ward, left in Mr. Rochester's care when her mother died. Mr. Rochester and Jane enjoy each other's company and spend many hours together.
    Odd things start to happen at the house, such as a strange laugh, a mysterious fire in Mr. Rochester's room, on which Jane throws water, and an attack on Rochester's house guest, Mr. Mason. Jane receives word that her aunt was calling for her, after being in much grief because her son has died. She returns to Gateshead and remains there for a month caring for her dying aunt. Mrs. Reed gives Jane a letter from Jane's paternal uncle, Mr John Eyre, asking for her to live with him. Mrs. Reed admits to telling her uncle that Jane had died of fever at Lowood. Soon after, Jane's aunt dies, and she returns to Thornfield. Jane begins to communicate to her uncle John Eyre.
    St. John Rivers admits Jane to Moor House.
    After returning to Thornfield, Jane broods over Mr. Rochester's impending marriage to Blanche Ingram. But on a midsummer evening, he proclaims his love for Jane and proposes. As she prepares for her wedding, Jane's forebodings arise when a strange, savage-looking woman sneaks into her room one night and rips her wedding veil in two. As with the previous mysterious events, Mr. Rochester attributes the incident to drunkenness on the part of Grace Poole, one of his servants. During the wedding ceremony, Mr. Mason and a lawyer declare that Mr. Rochester cannot marry because he is still married to Mr. Mason’s sister Bertha. Mr. Rochester admits this is true, but explains that his father tricked him into the marriage for her money. Once they were united, he discovered that she was rapidly descending into madness and eventually locked her away in Thornfield, hiring Grace Poole as a nurse to look after her. When Grace gets drunk, his wife escapes, and causes the strange happenings at Thornfield. Jane learns that her own letter to her uncle John Eyre, which happened to be seen by Mr. Mason, who knew John Eyre and was there, was how Mr. Mason found out about the bigamous marriage. Mr. Rochester asks Jane to go with him to the south of France, and live as husband and wife, even though they cannot be married. Refusing to go against her principles, and despite her love for him, Jane leaves Thornfield in the middle of the night.

    [edit]Other employment

    Jane travels through England using the little money she had saved. She accidentally leaves her bundle of possessions on a coach and has to sleep on the moor, trying to trade her scarf and gloves for food. Exhausted, she makes her way to the home of Diana and Mary Rivers, but is turned away by the housekeeper. She faints on the doorstep, preparing for her death. St. John Rivers, Diana and Mary's brother and a clergyman, saves her. After she regains her health, St. John finds her a teaching position at a nearby charity school. Jane becomes good friends with the sisters, but St. John remains reserved.
    The sisters leave for governess jobs and St. John becomes closer with Jane. St. John discovers Jane's true identity, and astounds her by showing her a letter stating that her uncle John Eyre has died and left her his entire fortune of 20,000 pounds (equivalent to over £1.3 million in 2011, calculated using the RPI[6]). When Jane questions him further, St. John reveals that John is also his and his sisters' uncle. They had once hoped for a share of the inheritance, but have since resigned themselves to nothing. Jane, overjoyed by finding her family, insists on sharing the money equally with her cousins, and Diana and Mary come to Moor House to stay.

    [edit]Proposals

    Thinking she will make a suitable missionary's wife, St. John asks Jane to marry him and to go with him to India, not out of love, but out of duty. Jane initially accepts going to India, but rejects the marriage proposal, suggesting they travel as brother and sister. As soon as Jane's resolve against marriage to St. John begins to weaken, she mysteriously hears Mr. Rochester's voice calling her name. Jane then returns to Thornfield to find only blackened ruins. She learns that Mr. Rochester's wife set the house on fire and committed suicide by jumping from the roof. In his rescue attempts, Mr. Rochester lost a hand and his eyesight. Jane reunites with him, but he fears that she will be repulsed by his condition. When Jane assures him of her love and tells him that she will never leave him, Mr. Rochester again proposes and they are married. He eventually recovers enough sight to see their first-born son.

    [edit]Characters

    • Jane Eyre: The protagonist of the novel and the title character. Orphaned as a baby, she struggles through her nearly loveless childhood and becomes governess at Thornfield Hall. Jane is passionate and opinionated, and values freedom and independence. She also has a strong conscience and is a determined Christian.
    • Mr. Reed: Jane's maternal uncle, who adopts Jane when her parents die. According to Mrs. Reed, he pitied Jane and often cared for her more than for his own children. Before his own death, he makes his wife promise to care for Jane.
    • Mrs. Sarah Reed: Jane's aunt by marriage, who adopts Jane on her husband's wishes, but abuses and neglects her. She eventually disowns her and sends her to Lowood School.
    • John Reed: Jane's cousin, who as a child bullies Jane constantly, sometimes in his mother's presence. He ruins himself as an adult by drinking and gambling and is thought to have committed suicide.
    • Eliza Reed: Jane's cousin. Bitter because she is not as attractive as her sister, she devotes herself self-righteously to religion. She leaves for a nunnery near Lisle after her mother's death, determined to estrange herself from her sister.
    • Georgiana Reed: Jane's cousin. Although beautiful and indulged, she is insolent and spiteful. Her sister Eliza foils her marriage to the wealthy Lord Edwin Vere, when they were about to elope. She also becomes a friend of Jane's towards the end of the novel and eventually marries a wealthy man.[7]
    • Bessie Lee: The plain-spoken nursemaid at Gateshead. She often treats Jane kindly, telling her stories and singing her songs. Later she marries Robert Leaven.
    • Robert Leaven: The coachman at Gateshead, who brings Jane the news of John Reed's death, which brought on Mrs. Reed's stroke.
    • Mr. Lloyd: A compassionate apothecary who recommends that Jane be sent to school. Later, he writes a letter to Miss Temple confirming Jane's account of her childhood and thereby clearing Jane of Mrs. Reed's charge of lying.
    • Mr. Brocklehurst: The clergyman, headmaster and treasurer of Lowood School, whose maltreatment of the students is eventually exposed. A religious traditionalist, he advocates for his charges the most harsh, plain, and disciplined possible lifestyle—but not, hypocritically, for himself and his own family. His second daughter Augusta hereby states: "Oh, my dear papa, how quiet and plain all the girls at Lowood look... they look at my dress and mama's, as if they never seen a silk gown before."
    • Miss Maria Temple: The kind superintendent of Lowood School, who treats the students with respect and compassion. She helps clear Jane of Mr. Brocklehurst's false accusation of deceit, and cares for Helen in her last days. Eventually she marries Reverend Naysmith.
    • Miss Scatcherd: A sour and vicious teacher at Lowood.
    • Helen Burns: Jane's best friend at Lowood School. She refuses to hate those who abuse her, trusting in God and praying for peace one day in heaven. She teaches Jane to trust Christianity, and dies of consumption in Jane's arms. Elizabeth Gaskell, in her biography of the Brontë sisters, wrote that Helen Burns was 'an exact transcript' of Maria Brontë, who died of consumption at age 11.[8]
    • Edward Fairfax Rochester: The master of Thornfield Manor. A Byronic hero, he is tricked into making an unfortunate first marriage to Bertha Mason many years before he meets Jane, with whom he falls madly in love.
    • Bertha Antoinetta Mason: The violently insane first wife of Edward Rochester; moved to Thornfield and locked in the attic and eventually commits suicide by burning down Thornfield Hall.
    • Adèle Varens: An excitable French child to whom Jane is governess at Thornfield. She has been Mr. Rochester's ward since the death of her mother, Rochester's mistress.

    • Leah: The young, pretty and kind housemaid at Thornfield, with an occasional excitable nature.
    • Blanche Ingram: A socialite whom Mr. Rochester temporarily courts in order to make Jane jealous. She is described as having great beauty, but displays callous behaviour and avaricious intent.
    • Richard Mason: An Englishman from the West Indies, whose sister is Mr. Rochester's first wife. He took part in tricking Mr. Rochester into marrying Bertha, earning both of their anger. He still, however, cares for his sister's well-being.
    • Grace Poole: Bertha Mason's caretaker. Mr. Rochester pays her a very high salary to keep Bertha hidden and quiet, and she is often used as an explanation for odd happenings. She has a weakness for drink that occasionally allows Bertha to escape.
    • St. John Eyre Rivers: A clergyman who befriends Jane and turns out to be her cousin. He is thoroughly practical and suppresses all his human passions and emotions in favour of piety. He is determined to go to India as a missionary, even if it means losing his love, Rosamond.
    • Diana and Mary Rivers: St. John's sisters and (as it turns out) Jane's cousins. They are poor, intelligent, and kind-hearted, and want St. John to stay in England.
    • Rosamond Oliver: A beautiful, wealthy young woman, the patron of the village school where Jane teaches. She falls in love with St. John, only to be rejected because she will not make a good missionary's wife.
    • Alice Wood: Jane's maid when she is mistress of the girls' charity school in Morton.

Rocket

                                       Rocket

                                       
  • rocket is a missilespacecraftaircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellants carried within the rocket before use.[Rocket engines work by action and reaction. Rocket engines push rockets forward simply by throwing their exhaust backwards extremely fast.
  • While comparatively inefficient for low speed use, rockets are relatively lightweight and powerful, capable of generating large accelerations and of attaining extremely high speeds with reasonable efficiency. Rockets are not reliant on the atmosphere and work very well in space.
  • Rockets for military and recreational uses date back to at least 13th century China. Significant scientific, interplanetary and industrial use did not occur until the 20th century, when rocketry was the enabling technology of the Space Age, including setting foot on the moon. Rockets are now used for fireworks,weaponryejection seatslaunch vehicles for artificial satellites,human spaceflight, and space exploration.
  • Chemical rockets are the most common type of rocket and they typically create their exhaust by the combustion of rocket propellant. Chemical rockets store a large amount of energy in an easily released form, and can be very dangerous. However, careful design, testing, construction and use minimizes risks

History of the rocket

                                           
  • The availability of black powder (gunpowder) to propel projectiles was a precursor to experiments as weapons such as bombscannon, incendiary fire arrows and rocket-propelled fire arrows.[nb 1][nb 2] The discovery of gunpowder was probably the product of centuries of alchemical experimentation in whichTaoist alchemists were trying to create an elixir of immortality that would allow the person ingesting it to become physically immortal.
    Exactly when the first flights of rockets occurred is contested. A problem is that Chinese fire arrows can be either arrows with explosives attached, or arrows propelled by gunpowder. There were reports of fire arrows and 'iron pots' that could be heard for 5 leagues (25 km, or 15 miles) when they exploded, causing devastation for a radius of 600 meters (2,000 feet), apparently due to shrapnel.A common claim is that the first recorded use of a rocket in battle was by the Chinese in 1232 against the Mongol hordes at Kai Feng Fu.However, the lowering of iron pots there may have been a way for a besieged army to blow up invaders.[nb 3] A scholarly reference occurs in the Ko Chieh Ching Yuan (The Mirror of Research), states that in 998 AD a man named Tang Fu invented a fire arrow of a new kind having an iron head.
    Less controversially, one of the earliest devices recorded that used internal-combustion rocket propulsion, was the 'ground-rat,' a type of firework recorded in 1264 as having frightened the Empress-Mother Kung Sheng at a feast held in her honor by her son the Emperor Lizong.
    Subsequently, one of the earliest texts to mention the use of rockets was the Huolongjing, written by the Chinese artillery officer Jiao Yu in the mid-14th century. This text also mentioned the use of the first known multistage rocket, the 'fire-dragon issuing from the water' (huo long chu shui), used mostly by the Chinese navy

Plant cell

                                       Plant cell

                                    

Cell type

  • Parenchyma cells are living cells that have diverse functions ranging from storage and support tophotosynthesis and phloem loading (transfer cells). Apart from the xylem and phloem in their vascular bundles, leaves are composed mainly of parenchyma cells. Some parenchyma cells, as in the epidermis, are specialized for light penetration and focusing or regulation of gas exchange, but others are among the least specialized cells in plant tissue, and may remain totipotent, capable of dividing to produce new populations of undifferentiated cells, throughout their lives. Parenchyma cells have thin, permeable primary walls enabling the transport of small molecules between them, and their cytoplasm is responsible for a wide range of biochemical functions such as nectar secretion, or the manufacture of secondary products that discourage herbivory. Parenchyma cells that contain many chloroplasts and are concerned primarily with photosynthesis are calledchlorenchyma cells. Others, such as the majority of the parenchyma cells in potato tubers and the seedcotyledons of legumes, have a storage function.
    • Collenchyma cells – collenchyma cells are alive at maturity and have only a primary wall. These cells mature from meristem derivatives that initially resemble parenchyma, but differences quickly become apparent. Plastids do not develop, and the secretory apparatus (ER and Golgi) proliferates to secrete additional primary wall. The wall is most commonly thickest at the corners, where three or more cells come in contact, and thinnest where only two cells come in contact, though other arrangements of the wall thickening are possible.[13]
    Pectin and hemicellulose are the dominant constituents of collenchyma cell walls of dicotyledon angiosperms, which may contain as little as 20% of cellulose in Petasites.[14] Collenchyma cells are typically quite elongated, and may divide transversely to give a septate appearance. The role of this cell type is to support the plant in axes still growing in length, and to confer flexibility and tensile strength on tissues. The primary wall lacks lignin that would make it tough and rigid, so this cell type provides what could be called plastic support – support that can hold a young stem or petiole into the air, but in cells that can be stretched as the cells around them elongate. Stretchable support (without elastic snap-back) is a good way to describe what collenchyma does. Parts of the strings in celery are collenchyma.
    • Sclerenchyma cells – Sclerenchyma cells (from the Greek skleroshard) are hard and tough cells with a function in mechanical support. They are of two broad types – sclereids or stone cells and fibres. The cells develop an extensive secondary cell wall that is laid down on the inside of the primary cell wall. The secondary wall is impregnated with lignin, making it hard and impermeable to water. Thus, these cells cannot survive for long' as they cannot exchange sufficient material to maintain active metabolism. Sclerenchyma cells are typically dead at functional maturity, and the cytoplasm is missing, leaving an empty central cavity.
    Functions for sclereid cells (hard cells that give leaves or fruits a gritty texture) include discouraging herbivory, by damaging digestive passages in small insect larval stages, and physical protection (a solid tissue of hard sclereid cells form the pit wall in a peach and many other fruits). Functions of fibres include provision of load-bearing support and tensile strength to the leaves and stems of herbaceous plants.[13] Sclerenchyma fibres are not involved in conduction, either of water and nutrients (as in the xylem) or of carbon compounds (as in the phloem), but it is likely that they may have evolved as modifications of xylem and phloem initials in early land plants.

    Tissue type

                                

  • The major classes of cells differentiate from undifferentiatedmeristematic cells (analogous to the stem cells of animals) to form the tissue structures of rootsstemsleavesflowers, and reproductive structures.
    Xylem cells[15] are elongated cells with lignified secondary thickening of the cell walls. Xylem cells are specialised for conduction of water, and first appeared in plants during their transition to land in the Silurianperiod more than 425 million years ago (see Cooksonia). The possession of xylem defines the vascular plants or Tracheophytes. Xylem tracheids are pointed, elongated xylem cells, the simplest of which have continuous primary cell walls and lignified secondary wall thickenings in the form of rings, hoops, or reticulate networks. More complex tracheids with valve-like perforations called bordered pits characterise the gymnosperms. The ferns and other pteridophytes and the gymnosperms have only xylem tracheids, while the angiosperms also have xylem vessels. Vessel members are hollow xylem cells aligned end-to-end, without end walls that are assembled into long continuous tubes. The bryophytes lack true xylem cells, but their sporophytes have a water-conducting tissue known as the hydrome that is composed of elongated cells of simpler construction.
    Phloem is a specialised tissue for food conduction in higher plants. The conduction of food is a complex process that is carried in the plant with the help of special cell called phloem cells. These cells conduct inter- and intra-cellular fluid (food – proteins and other essential elements required by the plant for its metabolism) through the process of osmosis. This phenomenon is called ascent of sap in plants. Phloem consists of two cell types, thesieve tubes and the intimately-associated companion cells. The sieve tube elements lack nuclei and ribosomes, and their metabolism and functions are regulated by the adjacent nucleate companion cells. Sieve tubes are joined end-to-end with perforate end-plates between known as sieve plates, which allow transport of photosynthate between the sieve elements. The companion cells, connected to the sieve tubes via plasmodesmata, are responsible for loading the phloem with sugars. The bryophytes lack phloem, but moss sporophytes have a simpler tissue with analogous function known as the leptome.
    Plant epidermal cells are specialised parenchyma cells covering the external surfaces of leaves, stems and roots. The epidermal cells of aerial organs arise from the superficial layer of cells known as the tunica (L1 and L2 layers) that covers the plant shoot apex,[13] whereas the cortex and vascular tissues arise from innermost layer of the shoot apex known as the corpus (L3 layer). The epidermis of roots originates from the layer of cells immediately beneath the root cap.
    The epidermis of all aerial organs, but not roots, is covered with a cuticle made of the polyester cutin with a superficial layer of waxes. The epidermal cells of the primary shoot are thought to be the only plant cells with the biochemical capacity to synthesize cutin.[16] Several cell types may be present in the epidermis. Notable among these are the stomatal guard cells, glandular and clothing hairs or trichomes, and the root hairs of primary roots. In the shoot epidermis of most plants, only the guard cells have chloroplasts.
