Venturi Meter: Flow Rate Measurement
A Venturi meter is a device used to measure the flow rate of an incompressible fluid in a pipe. It operates on the principle of Bernoulli’s equation, creating a pressure differential by gradually constricting the flow area (throat) and then gradually expanding it back. The pressure drop across the throat is directly related to the fluid’s velocity and, consequently, its flow rate. Its smooth contours minimize energy losses.

Gene Mutations: Types and Impacts
Gene mutations alter the nucleotide sequence of a single gene.
Base Substitutions
Base substitutions account for approximately 20% of all mutations. They involve the replacement of one DNA base with another, affecting only a single nucleotide.
Due to the degenerate nature of the genetic code, a mutated triplet may still encode the same amino acid; this is known as a silent mutation. If the new triplet codes for a different amino acid, it can have serious consequences,

Ortega y Gasset’s Philosophical Concepts
Reality is not a set of things that happen to us. It does not conform to preset patterns but uses “occasional” categories, whose meaning depends on the circumstances.
Ortega’s Concept of Reality
Ortega y Gasset identified two concepts of reality: what is real for us and actual reality. The reality that is “real to us” is what we encounter and must live with, whether we like it or not. The “true and primary reality” is an uncertain portfolio of facilities and

20th Century Spanish Theater: Realism, Avant-Garde, and Innovation
Early 20th Century Theater: Realism and Renewal
At the beginning of the 20th century, the predominant trend in drama was **realistic and naturalistic theater**. This was the most commercial form of theater, aiming to reflect the social reality of the moment. The characteristics of this stage included:
- Sets that created the illusion of reality for the viewer.
- Actors embodying characters as if they were real individuals.
- The audience forgetting they were in a theater.
During the first decades of this century,

Understanding Radioactive Waste
What is Radioactive Waste?
Radioactive Waste (RW) refers to material containing or contaminated with radioactive nuclei in concentrations higher than those set by authorities, for which there is no provision for later use. It is characterized by its severity and duration.
Types of Radioactive Waste
Waste is categorized based on its half-life (the time required for the number of radioactive atoms to be reduced by half) and specific activity (number of decays per unit time)

A social movement is a collective, organized effort to promote or resist change in society. Herbert Blumer defines it as “a collective enterprise seeking to establish a new order of life,” arising from unrest and driven by hopes for a better system.
Major Theories of Social Movements
Understanding why and how these movements emerge and function is explained through various theories:
1. Deprivation Theory
This theory suggests that social movements arise when people feel deprived of something they

The Romance: Medieval Poetry in the 14th Century
Medieval poetry continued into the 14th century with the emergence of the romance. These compositions, of variable extent, were written in eight-syllable lines with rhyming assonance in pairs. The earliest romances are known as the old romances.
The origin of this genre appears to be in the fragmentation of medieval epic poems, where each hemistich became a caesura in verse.
The oldest romances date back to the 15th century. While poetry was part of
