What is ESD?

ESD (Electrostatic Discharge) is the accumulation of electric charge on a surface. For a person to feel an ESD, it's necessary to accumulate 3000V of static electricity.

How to Prevent ESD

• Save all components in static-safe bags.
• Use grounded pads.
• Use grounded floor mats.
• Use an antistatic wrist strap when working with computers.

Types of Power Changes

• Total Blackout: Complete power outage.
• Partial Blackout: A reduction in voltage.
• Noise: Interference on the power line.
• Peak Voltage: A sudden, sharp increase in voltage.
• Overvoltage: A prolonged increase in voltage.

What is a Database?

A database is a structured data support system that allows us to store and process data quickly, safely, and efficiently.

A database consists of fields, records, and files. We define:

• Field: Each of the elements that make up a record, such as name, address, town, and telephone.
• Record: A set of interrelated fields, such as personal data belonging to a shareholder of a video store.
• File: Consists of the union of multiple records.

What is a Relational Database?

Using relational databases is useful when multiple records of a database are related to the same record in another database. A simple and intuitive way of structuring data is using tables, i.e., arranged in rows and columns. The relational model uses the table structure for...

The crowd, also called a mass, is characterized by a group of more than 50 individuals, with little connection between them and whose purposes are not always clear. Feelings and beliefs are dormant and emotions are transmitted quickly. Example can be a big camp.

The band: Formed by a few individuals with a search for similarities between them. The similarity is the basis of... Continue reading "Concept of education" »

Accounting and Its Function

Accounting serves to collect and quantify economic-financial information generated within a business. This information is then communicated to end-users so that, once verified and analyzed, it can influence decision-making.

Accounting Information

Key components of accounting information include:

1. Mandatory accounting books
2. The annual accounts (balance sheet and profit and loss account)
3. The accounting mechanics

Required Accounting Books

• Accounting-General Plan: Mandatory annual accounts for small companies:
  • Balance sheet
  • Income statement
  • Statement of changes in equity
  • Notes
• Commercial Code:
  • Book inventory and annual accounts
  • General ledger

Functions of the European Parliament

Legislative Role

Parliament participates alongside the Council in the legislative process. The standard procedure for approving legislation is codecision, where Parliament and the Council are on equal footing and adopt standards using this procedure. Parliament has limited powers in drafting legislation.

Budgetary Function

This function gives Parliament significant power because it can modify and change the spending approved by the Council. Parliament must approve the EU budget jointly with the Council and may make modifications. Parliament's budgetary control committee monitors how the budget is spent.

Democratic Role

Parliament exercises a supervisory role over the Commission. When appointing a new Commission,... Continue reading "Understanding the EU: Parliament, Council, and Commission" »

Product Characteristics

• Packaging: Facilitates transport, storage, and preservation.
• Expanded Product: Includes additional services like home delivery and technical support.

Pricing Methods

1. Cost-Based: Add desired

Multi-Circuit: Intermittent Power Supply

This electronic circuit provides intermittent power and can be supplemented with a device that detects malfunctions by placing two additional transistors.

Veri.Mani: Pilot Testing and Reverse Voltage

Pilot testing began with a system that does not function in reverse voltage to current.

Fuel Level Sensors: Analog and Digital Indicators

Fuel level sensors are responsible for displaying the amount of liquid in a deposit. These can be analog or digital and are based on the principle of a float or rheostat.

Oil Pressure Monitoring: Lamp and Monocontacto

Quality Product Criteria

A quality product achieves its desired objective at the lowest possible cost.

Quality Healthcare Professionals

Quality healthcare professionals require suitable facilities, advanced technology, and adequate training.

Detecting Quality: Manager's View

Effectiveness is the most detectable quality characteristic for managers. It means achieving objectives efficiently, allowing resource allocation to other needs.

User Perspective on Quality Healthcare

Users value proper personal care, effective treatments, continuity, and efficiency.

Scientific-Technical Quality vs. User Efficiency

Scientific-technical quality is often overlooked by users, especially in public health systems where the cost-benefit relationship isn't direct.

Respiratory System

The respiratory system is formed by the ducts through which air circulates, and by small cavities called alveoli, which are capable of entering the bloodstream. At the same time, blood circulates CO2 through the tubes of the respiratory system.

Upper Respiratory Tract

• Nose and nostrils: Two cavities located in the center of the face. Function: To warm and moisten the air.
• Pharynx: Connects the mouth with the larynx and nasal passages. It also communicates through the auditory tube. It forms part of the respiratory and digestive tracts.
• Larynx: Formed by cartilage and bone, it connects the pharynx with the trachea. It contains the vocal cords, which vibrate with airflow to produce the voice.

Lower Respiratory Tract

• Trachea: A tube

Substantial Changes in Working Conditions

When justified by economic, technical, organizational, or production reasons, a company may modify working conditions such as daily hours, shift work, compensation, work systems, and performance features, provided the change exceeds functional mobility limits.

These changes must be communicated to the worker and their legal representatives at least one month in advance. If the worker disagrees, they may appeal to a labor court. Collective changes require a consultation period of at least 15 days with the workers' legal representatives before the company can notify the changes to the workers.
