Management of the Prevention of Risks in the Enterprise

Management has changed throughout history with the changes in the ways of understanding work and has influenced such important factors as:

• The economic cost of damage and injury accidents.
• The industrial action of the union movement.

Remember that the management of risk prevention should be characterized as scientific, interdisciplinary, comprehensive, integrated, and participatory. The obligation of any manager is to manage resources, both material and human, for economic and social benefits, so they generate satisfactory working conditions.

Methods to Assess Occupational Risks

These methods allow to assess and rank their degree of danger, to facilitate its correction. Some methods, such as... Continue reading "Occupational Risk Prevention and Management in the Workplace" »

Types of Industrial Agitators and Mixers

The most commonly used agitators are the rotary type. Other types include pendulous, bubbling, flow mixers, centrifugal pumps, colloid mills, and ultrasonic vibrators.

Rotary agitators are classified according to the shape of the runner (impeller) and their speed:

High-Speed Rotary Agitators (High Revolution)

These agitators allow mixing in a shorter time. However, due to the increased energy supply provided to the product, it may undergo thermal degradation.

• Propeller (Helix) Agitators

  The impeller consists of a helix of two, three, or four blades. They work at high speeds, creating significant turbulence in the area near the impeller.

• Turbine Agitators

  These are centrifugal pump impellers working without a

Water Safety: Accident Prevention

Speaking about the prevention of water rescue, one must refer to actions that are in place to prevent the occurrence of accidents. Fortunately, these actions are much more common than lifesaving.

Causes of Aquatic Accidents

In general, accidents can be attributed to:

• Access to risk.
• Ignorance, neglect, or underestimation of risk.
• Lack of resources for prevention and intervention (lifeguard, signs, information boards, etc.).
• Inability to cope with the difficulties encountered.

Principles of Aquatic Accident Prevention

Establishing an effective prevention system in a particular aquatic environment involves the proper development of the following principles:

• Identification of risks.
• Control of risks.
• Elimination of risks.

Securities Market Act and the National Securities Market

The Securities Market Law regulates primary and secondary markets of securities. It lays down the principles of its organization and operation, the rules governing the activities of those involved in them, and the monitoring regime.

The issuance of securities should be reported to the National Commission for Securities Market, which is the body designated by the Securities Market Law for that matter.

The National Securities Market

The LMV requires the existence of a public law entity with legal personality and capacity to exercise the functions assigned to it by law and the Ministry of Finance in monitoring and inspection of the securities markets and a few people involved in them.

The CNMV... Continue reading "Securities Market Act: Regulation and Investment" »

Software Validation and Verification Fundamentals

Objectives of Validation and Verification

• Detect and correct defects as soon as possible.
• Reduce risks of budget and timetable deviations.
• Improve software quality and reliability.
• Improve development process management visibility.
• Quickly assess proposed changes.

Philosophy of Software Testing

Recommendations by G.J. Myers:

• Each test case should define the expected output.
• Programmers must avoid testing their own programs.
• Thoroughly inspect test results to identify possible symptoms of defects.
• Test case generation should include valid, invalid, and unexpected inputs.
• Prove that the software performs as intended and avoids unintended actions.
• Test plans should always assume the presence of defects to avoid

Wage Slip

With a wage, the employer is obligated to provide the employee a document known as a wage slip, also known as a payroll slip, specifying individual earnings as well as deductions.

Contribution Base

The contribution base is an amount calculated in relation to workers' salaries, on which tax rates apply for contributions to be deducted from the payroll.

Perceptions (Non-Wage Benefits)

Transport is of great importance in Spain, particularly in its more developed cities. It is a system that facilitates the movement of people and goods through interconnected infrastructure networks, including roads, ports, airports, and railways.

Characteristics of the Spanish Transport System

The Spanish transport system exhibits several distinct characteristics:

• Influence of the Natural Environment: The challenging relief necessitates the construction of expensive bridges and tunnels, increasing infrastructure costs.
• Radial Network Centered in Madrid: The network, particularly roads and railways, is predominantly radial with Madrid as the central hub. This radial structure also significantly impacts air transport, as Madrid hosts numerous domestic

Ecological Reserves

An ecological reserve is a natural area, either virgin or semi-virgin, where numerous animal and plant species coexist alongside abiotic factors such as water, soil, and sunlight. The role of an ecological reserve is to protect a natural area in its current state to maintain its unmodified condition. Many ecological reserves exist worldwide, including Shark Island in Sonora, Calakmul in Quintana Roo, and the Centla Swamps biosphere reserve in Tabasco, among others.

National Parks and Nature Reserves

National parks and nature reserves are areas selected by governments or private organizations for special protection against deterioration and environmental degradation. Selection criteria vary, encompassing natural beauty, scientific... Continue reading "Ecological Reserves and National Parks" »
