Introduction to the ECHR

The European Convention on Human Rights (ECHR) is an international treaty adopted in 1950 under the framework of the Council of Europe. It entered into force in 1953 and currently applies to 46 member states. The ECHR establishes a catalog of fundamental rights and freedoms, including the right to life, prohibition of torture, freedom of expression, and the right to a fair trial. It is based on key principles such as the rule of law, democracy, and the protection of human dignity.

The European Court of Human Rights (ECtHR), located in Strasbourg, is responsible for interpreting and enforcing the Convention, ensuring that states comply with their obligations. Through its case law, the ECtHR has developed crucial legal... Continue reading "Analyzing ECHR Violations: A Framework for Legal Cases" »

The Alhambra: Nasrid Architectural Masterpieces

Courtyard of the Lions

The Courtyard of the Lions features a criss-cross water channel system connecting the courtyard to the surrounding rooms, forming a cruciform compositional axis. The courtyard is surrounded by slender columns and porticos.

• Fountain of the Lions: Features 12 lion sculptures. The design evokes the image of an oasis, characterized by small, provisional-looking columns adorned with vegetation carvings.

Hall of the Two Sisters

This was the most important room, serving as the residence of the King and the main hall. It features its own fountain and represents the beginning of the complex's design philosophy.

• Architecture: Main hall with a dome, repetition of geometric patterns (geopatterns)

Renaissance Concepts and Classical Revival

• Renewed Interest in Antiquity: Manifested early in literature and poetry through figures like Dante, Petrarch, and Boccaccio.
• Classical Texts: Significant revival and rediscovery of ancient writings.
• Vitruvius's Treatise (1414): The rediscovery of De Architectura was profoundly influential for subsequent generations of architects.

The Rise of Architectural Patronage

The emergence of wealthy patrons promoted new forms of art and architecture. Key examples include:

• The Medici Family: Including Giovanni di Averardo, Cosimo de' Medici (il Vecchio), and Lorenzo de' Medici (il Magnifico).

Humanism and Anthropocentrism

• Humanism posits that the human being contains the perfect proportions of the universe, famously

Santa Maria degli Angeli (Florence)

(Demolished after 3 years)

• Blended integration and relation of elements.
• Centralized floorplan: Representing an aesthetic ideal and an expression of the order of the universe – absolute symmetry.
• Surrounded by a world of well-proportioned beauty.
• Relation with Villa Rotonda; centralized building as a key urban form.

Michelozzo: Palazzo Medici (Florence)

• An urban palace where the facade is an important aspect.
• The wall treatment softens and smooths in the upper levels, representing the wealth of the Medici family.
• Exterior conveys solemnity, giving higher status to the city as well.
• Features a very heavy cornice at the top.

Leon Battista Alberti: Theory and Practice

• Had extensive contact with Florentine Humanists; friend

Performance Metrics

• Elapsed Time: Represents overall system performance. It is the total time taken to complete a task.
• User CPU Time: Indicates CPU performance. It is the time the task actively runs on the CPU, excluding idle time.
• CPU Time: The time the CPU spends executing instructions, either from the task or the operating system, excluding idle time.
• Clock Speed: 1 MHz equals 1 million clock cycles per second. 1 GHz equals 1 billion clock cycles per second.
• Response Time: Equivalent to execution time.
• Throughput: Equivalent to bandwidth.
• Performance Comparison: (PerfA) / (PerfB) = (ExecTimeB) / (ExecTimeA) = n

Impact of Processor Upgrades

• Replacing a processor with a faster one decreases response time and increases throughput.
• Adding an additional

Early Hominid Origins and Evolution

Definition of Hominid

• Bipedal: Walking on two feet.
• Non-honing Dentition: While humans have non-honing chewing, primates such as gorillas have a honing complex, in which their very large canines cut food. The upper canines are sharpened against the lower third premolars.

Skeletal Evidence for Bipedalism

Foramen magnum, pelvis, knees, feet: seven steps, position of the foramen magnum, shape of the spine, shape of the pelvis, length of the leg, valgus knee, longitudinal foot arch, opposable big toe.

Behavioral Advantages of Bipedalism

This helps to identify what species they were because not many can be bipedal.

Pre-Australopithecines (7-5 mya)

Example: "Ardi"

They have provided critically important information about... Continue reading "Early Hominid and Homo Evolution: A Deep Dive" »

Implementação da Transposição de Matriz 4x4 em C

Este programa em C demonstra como calcular e exibir a matriz transposta (B) de uma matriz quadrada de ordem 4 (A). A transposição é realizada trocando as linhas pelas colunas, ou seja, o elemento na posição A[i][j] é copiado para B[j][i].

Código Fonte em C para Transposição de Matriz

O código utiliza as bibliotecas padrão stdio.h para entrada/saída e conio.h (comum em ambientes legados) para controle de console.

#include <stdio.h>
#include <conio.h>

int main()
{
    int i, j, A[4][4], B[4][4];

    // 1. Entrada de Dados
    printf("Insira os elementos da Matriz A (4x4):\n");
    for(i = 0; i < 4; i++)
    {
        for(j = 0; j < 4; j++)
        {
            printf(

Scientific knowledge (Overview and Basic Concepts)

Common sense knowledge is important, is generalized. Scientific knowledge has many steps that must be applied to determine if the hypothesis is true or situción. Do not generalize from one case.

Knowing is an intellectual process by which a relationship between the knower (actor) and the known object (reality).

There are glances of psychology:

1) Positivists: You must show, watch for it to be valid, measure, quantify, and so on. (It is science based on evidence).

a) Post-positivist Probalan is added, it may be or not. Deductive (general to particular).

2) Phenomenology: Is the experience, emotions, phenomena. Study what is not necessarily observable. Inductive method (particular to general)

Atherosclerosis: Pathogenesis & Complications

A chronic inflammatory disease of medium and large arteries, caused by endothelial injury and lipid accumulation.

Key Risk Factors:

• Hypertension
• Hyperlipidemia
• Smoking
• Diabetes

Lesions evolve from fatty streaks → fibrous plaques → complicated plaques.

Common Complications:

• Myocardial Infarction (MI)
• Stroke
• Aneurysm
• Peripheral Artery Disease

Histologically, it shows lipid cores, calcification, and fibrous caps.

Hypertensive Disease: Organ Damage & Malignant Forms

Chronic blood pressure (BP) elevation causes vascular and organ damage.

Consequences Include:

• Arteriolosclerosis
• Left Ventricular (LV) hypertrophy
• Stroke
• Chronic Kidney Disease

Malignant hypertension (diastolic BP >120 mmHg) causes fibrinoid necrosis... Continue reading "Essential Pathology Topics: Systemic Diseases & Neoplasms" »
