Written at on English with a size of 2.7 KB.

The Waste Land by T.S. Eliot

1. Sections and Summaries

This poem comprises five sections:

  • The Burial of the Dead

    Part I conveys a sense of apprehension and incomprehension among various characters in different situations. Madame Sosostris, a fortune-teller, adds to the confusion with enigmatic pronouncements that only gain clarity later in the poem. The city, particularly London, is depicted as a grim place inhabited by people unable to live fully or escape their deadness.

  • A Game of Chess

    Part II presents two scenes showcasing the desolation of people's lives. The first depicts a richly decorated room where a wealthy lady's constant questions reveal her anxiety and lack of control. The second scene unfolds in a London pub, where two women discuss

The Reign of Isabel II (1833-1868)

The reign of Isabel II can be divided into two main phases: her minority, with two regencies (her mother, Maria Cristina of Naples, who was soon confronted by the Carlist Wars, and General Espartero), and her majority, which went through three stages: the Moderate Decade, the Progressive Biennium, and the Liberal Union.

Regency of Maria Cristina (1833-1840)

Maria Cristina faced two major problems: war and the institutional organization of the liberal regime.

Sebastian F. Ramallo Asensio (Universidad de Murcia)

Militum deinde quod eos non conlaudavit virtutem eruptio hostium, non altitudo moenium, Stagni inexplorata non vada, non castellum in high Tumulo situm, non munitissima arx deterruisset quo minus transcenderent omnia perrumperentque.

(T. Livy, XXVI, 48, 4)

This text of the History of Rome Livy clearly expresses components of the defensive apparatus of the city founded by Hasdrubal: the height of its walls, the shallow lagoon unexplored, the fortress located on high hill and the well-defended fortress components, all of which, coupled with the excellent conditions of its harbor and its strategic position in the communication routes to Africa and Italy through the Balearic Islands (Appian,

Synthesis and Sources of Aromatic Hydrocarbons

Classified in Chemistry

Written at on English with a size of 3.14 KB.

Preparation of Naphthalene

Naphthalene is a fused-ring aromatic hydrocarbon with two benzene rings. It can be prepared via the following methods:

  • From Coal Tar: Coal tar, a by-product of coal processing, is a major source of naphthalene. It is extracted and purified using distillation followed by crystallization.
  • Synthesis from Benzene: Benzene undergoes a series of reactions to form naphthalene:
    • Alkylation: Benzene reacts with alkyl halides (like methyl chloride) to form methylbenzene (toluene).
    • Cyclization: Toluene undergoes further reaction with chlorine and heat to form naphthalene.

Preparation of Anthracene

Anthracene is a tricyclic aromatic hydrocarbon consisting of three fused benzene rings. It is mainly obtained from coal tar but can also... Continue reading "Synthesis and Sources of Aromatic Hydrocarbons" »

Insect Defenses Against Predators

Three Plant Mechanisms to Defend Against Insects

  • Physical: Thick walls
  • Chemical: Phytochemicals that kill insects
  • Entrapment: Pitcher plants

How Insects Overcome Physical Defenses

  • Specialized mandibles
  • Evolution
  • Immunity to phytochemicals
  • Specialization to survive the digestive liquid of pitcher plants

Insect Parasitism

Endoparasites

Approximately 20% of insect orders include endoparasites. Some orders that include endoparasites are:

  • Hymenoptera
  • Diptera
  • Strepsiptera

Ectoparasites

Some orders that include ectoparasites are:

  • Anoplura
  • Mallophaga
  • Siphonaptera

Three Challenges Faced by Endoparasites

  • Respiration
  • Excretion/getting rid of toxic nitrogenous waste without killing the host
  • Avoiding the host's endocrine system
