• Reserves and undistributed profits (self-financing):
  • From enrichment: Legal Reserve, Statutory Reserve, and Voluntary Reserve
  • Maintenance: Depreciation and provisions

External Financing

• Based on Term:
  1. Short Term: Commercial loans, factoring, discounting of bills, financial credits, and bank loans.
  2. Long Term: Loans, leasing, renting, loans for fixed assets, bonds or obligations.
• Based on Origin:
  1. Internal Funding: Reserves or undistributed assets.
  2. External Funding: Other sources.
• Other External Funding:
  1. Grants and aid: Economic quantities that governments provide to entrepreneurs who meet

Karl Marx's Core Ideas and Critique

Karl Marx's most important influences on contemporary anthropological thought come from German idealist philosophy, especially Hegel, the materialism of Feuerbach, French utopian socialism, and great capitalist economic theorists such as David Ricardo and Adam Smith.

Major Works by Karl Marx

His extensive body of work includes: The Holy Family, The German Ideology, The Communist Manifesto, and Capital.

Materialist Philosophy vs. Idealism

Against idealist philosophy, which he saw as speculative, merely theoretical, or false ideology, Marx proclaimed a materialist philosophy: one that is useful, responsible, efficient, and committed to changing the world.

Marx's thought stems from a critical attitude towards a reality... Continue reading "Karl Marx's Influences, Philosophy, and Critique" »

Production: Definition and Objectives

Production is the process by which certain significant items, work, machines, working people, or knowledge are transformed into consumer products, goods, or services.

Production Goals

• Ensure that delivered products or provided services are requested, both in the amounts and on the dates agreed upon with the customer.
• Ensure that these products or services are manufactured or provided within the expected costs, and that these costs are minimal, for greater profit.

Description of Output

This is to determine in detail the procedure to be followed and the means employed to produce the products or services.

Stages of the description of the production:

• Define the parameters of the production process
• Determine the necessary

Gases, Vapors, and Associated Risks

A gas is matter neither liquid nor solid at room temperature and normal atmospheric pressure, expanding to fill any container. A vapor is the gaseous state of a substance typically solid or liquid. Fumes result from volatilization or sublimation. Gases and vapors diffuse freely, remaining mixed with air.

Lead Poisoning

Metabolism

Inhaled lead is 40-60% retained in the lungs, entering circulation. Ingested lead absorption is about 10%. Blood lead distributes to liver, kidneys, brain, and bone. Elimination occurs via respiratory tract, gastrointestinal system (bile, feces), urine, and generalized discharges (colic).

Pathological Effects

• Hematologic: Altered metabolism via enzyme changes and metabolite accumulation.

Core Computer Architecture Components

CPU Registers Explained

CPU registers are small, high-speed storage locations within the central processing unit (CPU) that hold data and instructions for immediate processing.

Accumulator Register

The Accumulator Register stores the results of executed operations. It connects to input registers for feedback in chained operations and also connects to the data bus for sending results to main memory or the control unit.

Program Counter (PC)

The Program Counter (PC) stores the memory address of the next instruction to be executed.

Instruction Register (IR)

The Instruction Register (IR) contains the instruction currently being executed.

Understanding Computer Buses

A bus is a channel or set of parallel connections that... Continue reading "Computer Architecture Fundamentals: CPU, Memory, Buses, and Addressing" »

The Enlightenment and Pre-Romanticism

The eighteenth century began under the influence of the Enlightenment, a rationalist movement that posed a critical review of ideas and values in force until then. It is also known as the Age of Reason.

Moreover, in the second half of the eighteenth century, pre-Romanticism began in some European countries. This movement, a reaction against rationalism, reached its peak in the nineteenth century.

18th Century Society & Culture

Eighteenth-century society underwent profound social and political transformations, culminating in two significant historical events: the independence of the United States of America and the French Revolution (1789).

In most European countries, absolute monarchs and ecclesiastical... Continue reading "The Enlightenment Era: Society, Thought, and Transformations" »

Electronic Display Technologies

1. Seven-Segment Display

Comprised of seven LEDs arranged to produce the idealized representation of a number. An optional eighth LED can serve as a decimal point. The number of management-control signals for each display is N = segments + DP. In multiplexed mode, the number of necessary control signals is N = segments + DP + viewers.

Variants

Alphanumeric seven-segment displays add extra segments to represent alphanumeric characters. These have largely been replaced by LED matrix displays.

2. LED Matrix Display

An array of LEDs that can generate characters, symbols, and pictures. The number of control signals required for each display is N = rows + columns.

3. Vacuum Fluorescent Display (VFD)

Composed of filaments,... Continue reading "Electronic Display Technologies: A Comprehensive Overview" »

Observation: Concepts and Features

Observation is an inherent part of human nature, integrated into our psychology in relation to everyday events. It involves the perception of a phenomenon that is selected and recorded without manipulation, making the observer a passive witness of what has occurred.

Observation can vary in its degree of systematization, ranging from casual observation to those that adhere to strict methodological criteria.

Observation becomes a scientific technique when it meets the following criteria:

• It is part of an objective investigation.
• It is stated and recorded systematically.
• It is subject to checks and controls regarding validity and reliability.

Types of Observation

Self-Observation

Self-observation occurs when the observer... Continue reading "Understanding Observation: Types and Techniques" »

Active Directory provides a method to design a directory structure that meets the needs of any organization. It has many advantages, such as system scalability and ease in locating resources throughout a network.

• Active Directory allows a single point of management for all public resources, which may include files, peripheral devices, connections to databases, web access, users, services, etc.
• It uses the Internet DNS as the location service.
• Active Directory components are used to build a directory structure reflecting the needs of an organization.

Logical Structure

The logical structure of the organization is represented by domains, organizational units, trees, and forests.

• Domain: The central unit of the logical structure of Active Directory is

Lifeguard Surveillance: Core Principles

Monitoring is the task that occupies most of a lifeguard's time. Throughout their shift, many minutes are spent near the water, with the rescuer alert to any eventuality that may require intervention. When establishing a monitoring system, it must adhere to several key aspects to ensure maximum effectiveness:

• Number of lifeguards
• Location of the lifeguard station
• Static or dynamic monitoring
• Strategies for area control
• Surveillance shifts

Lifeguard Staffing: Determining Optimal Numbers

Lifeguard numbers should be determined based on:

• Configuration and size of the swimming area to cover (e.g., number of pools, their layout)
• Number of users
• Available equipment (e.g., high chairs, first aid stations)
• Activities taking
