Madrid’s Evolution: From Fortress to Modern Metropolis
The Origin of Madrid

Franco State Creation
The Francoist regime centralized power in Franco, with ideological components such as anti-communism (anti-Reds), anti-parliamentarism (democracy equated with Marxism), nacionalcatolicismo (strong Church presence), and traditionalism (exalting Castilian symbols and history). Francoist propaganda labeled regional autonomy as anti-Spanish. The military regime exhibited several fascist traits.
The dictatorship restored the oligarchy’s hegemony, supported

Plato (428 – 347 BC)
Ser = Immutability
The Foundation of Metaphysics: 1st and 2nd Navigation
Metaphysics (also called first philosophy by Aristotle) deals with realities beyond the physical and tangible. It asks about the Ente, the first principle of knowledge: what cannot be simply demonstrated but becomes the basis of all knowledge, unifying all human understanding.
For Plato, metaphysics is linked to what he called the 2nd navigation. The first, “driven by the winds” (naturalist philosophers), failed

Hume’s Treatise on Human Nature: Book One Summary
This text analyzes the principle of causality, which Hume denies. It delves into epistemology, basing human knowledge on the origin of ideas. Hume advocates for a radical empiricism, asserting that true ideas originate from sensory experience. He argues that all material is formed by perceptions, the mind’s basic elements of knowledge.
Perceptions: Impressions and Ideas
- Impressions: Primary, sensitive elements.
- Feelings: From external experience.

1. Water: A Scarce Resource
1.1. Concepts
- Watershed: Land and water aquifers providing a river’s course.
- Ephemeral River: A river with intermittent flow.
- Fluvial: Variation of river flow.
- Flood: Maximum river flow period.
- Low Flow: Minimum river flow.
1.2. Slopes and Watersheds

Understanding Fascism and Authoritarian Regimes: Origins, Rise, and Characteristics
Derex Fascism and its Authoritarian Features:
- Rejection of the Bourgeois World: After the war, many claimed a community spirit, camaraderie, heroism, and solidarity. There was nostalgia for past hierarchical societies.
- Disdain for Liberal Politics: They rejected parliamentary democracy and considered it a weak political system, unable to stop social revolution and ineffective in establishing an economic and social alternative. They held liberalism and democracy responsible for national defeat and
Exploring Oceania: Society, Control, and Rebellion in 1984
Setting the Scene: London, Oceania
The story unfolds in London, a city within the totalitarian state of Oceania. Oceania emerged after a revolution against capitalism, now ruled by the Party, led by the enigmatic Big Brother, and guided by the ideology of Ingsoc (English Socialism).
The Iron Grip of Ingsoc
Oceania operates without explicit laws, yet citizens instinctively know what actions are permissible and the consequences of transgression. The Party enforces its control through various means:

Origins of Political Power: Exploring Social Contract Philosophies
Theories of the Social Contract
The theories of contract are schools of thought using a hypothetical contract to explain the origin and legitimacy of state political power. This social contract arises from a supposed state of nature prior to social order. In a free state, autonomous individuals agree to organize a society. They decide the ruler’s functions and powers. Power’s legitimacy comes from the community members’ recognition of the contract. The contract is hypothetical; the state of nature

SRT (Shortest Remaining Time)
The next process to enter the processor is the one with the shortest remaining runtime. When a new process arrives with a shorter runtime than the currently running process, the latter is evicted from the CPU, and the shorter process begins execution. It’s a preemptive variant of the Shortest Job Next (SJN) algorithm.
Features:
- Variation of SJN.
- Preemptive policy.
- Very efficient.
- Possibility to assign priorities, where the system adjusts runtime based on priority (multiplying
Steam Power and Internal Combustion Engines: Principles and Operation
Cycle of Steam
The majority of installations for power generation from burning fuel (thermal) are steam-based, and these plants work according to variations of the Rankine thermodynamic cycle.
Plants usually utilize water steam as the working fluid and operate by burning solid, liquid, or gaseous fuel. Its main components are illustrated in Figure 3.1, where one can identify:
- Steam turbine
- Condenser
- Feed pump
- Boiler (steam generator)
- Chimney
- Electric Generator
- Cooling System (cooling tower)
As seen in Figure
