Semiconductor Properties, Types, and Applications in Electronics
Intrinsic Semiconductors: Semiconductors whose electrical properties are due to their own nature, that is, the atoms such as composition (electronic configuration) and its crystal structure.
Extrinsic Semiconductors: Semiconductors in which impurities, either givers or acceptors, are added. The number of electrons and holes (charge carriers that are normally equal in intrinsic semiconductors) are different, so we can talk about majority carriers (electrons or holes).
N-type Extrinsic Semiconductor:

Globalization: A Critical Standpoint
Key Considerations
Economic Impacts
The general opening of markets for goods and capital suggests the end of trading blocs, regional treaties, and economic independence of countries. It also facilitates the ability to solve economic needs local players have been unable to satisfy. The increasing privatization of economic sectors, with the rise of multinational corporations and the decline of state and national influence, is evident. Increased competition enhances
Read MoreComputer Fundamentals: Components, Operation, and Data Storage
What is a Computer? A computer is an electronic machine used to process digital information. Digital information is expressed in terms of 0 and 1, i.e., in binary numbering.
Basic Operation
- We provide input data to the computer in digital format.
- The computer processes these inputs according to the program instructions being executed. This is mainly carried out by the microprocessor (CPU), but also involves:
- RAM: Temporarily storing data and instructions.
- Graphics Card: With its own processor and RAM.
Franco’s Spain: Dictatorship, Economy, and International Relations
Overview: Franco’s regime established a military dictatorship characterized by authoritarianism, social conservatism, and the suppression of political freedoms. The Catholic Church and Spanish nationalism played paramount roles.
Social Protection: The regime protected four major groups: the military, the Catholic Church, Falangists, and Monarchists. Franco aimed to maintain a balance of power without consolidating absolute authority. Social protection extended to large landowners, financial-industrial

DYNAMIC EARTH
The Earth is not a static layer of rock but is in continuous transformation.
A) The Earth’s Crust
- The continental crust has a thickness of 35-40 km, with a varied mineral composition (outer granitic and basaltic layers).
- Continents extend hundreds of kilometers under the oceans in the so-called continental shelf, ending in a slope called the continental slope.
- The oceanic crust has a homogeneous thickness of about 7 km, with a basaltic composition and young rocks. It occupies more than

Understanding Reinstatement and Termination of Employment
Reinstatement to Work and Duration of Suspension

This period is not determined in general by the Act but shall be a reasonable period after the removal of the cause of the suspension (the day following the suspension sanction, or when the time allowed in the case of force majeure runs out, or after medical discharge). In some cases, the law
