Water Hardness

Hard water is water that contains appreciable amounts of dissolved calcium and magnesium compounds. These compounds form insoluble precipitates with soap. Ion exchangers are used to remove the hardness.

Temporary Hardness

Temporary hardness is caused by the presence of calcium and magnesium bicarbonates. It can be eliminated by heating the water to precipitate the calcium carbonate:

Ca(HCO₃)₂ → CaCO₃↓ + CO₂ + H₂O

Permanent Hardness

Permanent hardness refers to the remaining calcium and magnesium salts (not bicarbonates). It requires the addition of chemicals for removal, for example:

Na₂CO₃ + CaCl₂ → CaCO₃↓ + 2NaCl

Love of Jesus and Discipleship

The life of Jesus is the most perfect expression of love for God, and the disciple should strive to follow the same way: "Love one another as I have loved you." These words of Jesus are clear: they speak of a total, concrete, and real love, a love characteristic of true lives as children of God and brothers. Loving others is the sign of the love of God; you cannot love God without loving others, and vice versa. It is the characteristic of the disciples of Jesus: "By this everyone will know that you are my disciples, if you love one another."

Jesus brought to the world the Kingdom of God — a kingdom of peace, love, justice, and fraternity. This kingdom is now established in the world as a seed called to grow. Our

Selectivity in Chemical Analysis

A reaction used in chemical analysis is selective when the reaction is characteristic of few substances, showing a preference for some of these. When the reaction is carried out only on a particular substance, it is specific.

Limit of Detection (LOD)

Refers to the minimum amount of a substance that can be detected in a trial.

Sensitivity of Analytical Methods

The ability of a method to discriminate a change in concentration caused by a variation in the measurement of the analytical signal.

Qualitative vs. Quantitative Analysis

The science that studies the principles and techniques of chemical analysis. It is divided into:

• Qualitative analysis: Its purpose is the identification of the constituents of a sample (organic

Lung Cancer Classification and Characteristics

Small Cell Lung Cancer (SCLC)

• Usually originates in a central location.
• High risk of lymph node metastases.
• Most patients present with metastases at diagnosis.

Non-Small Cell Lung Carcinoma (NSCLC)

• Adenocarcinoma

  • Usually peripheral.
  • More frequent in nonsmokers and women.
  • High risk of lymph node invasion and distant metastases.

• Squamous Cell Carcinoma

  • The most common of all lung cancers.
  • Normally affects the bronchi.
  • High risk of nodal involvement.

• Large Cell Carcinoma

Other Lung Tumors

• Carcinoid Tumors

Oncological Treatment for Lung Cancer

Treatment for Stages I and II Lung Cancer

Codes

Communication codes are legion: the languages of mankind, color codes, writing, and language.

Parameters

• Amplitude: The maximum variation of the signal about the value zero.
• Period: The time lag between two consecutive steps by maximum wave value.
• Frequency: The number of oscillations that occur during

Need for Achievement (nAch)

• nAch = Need for achievement
• Motives of individuals or groups to seek challenging goals.
• Correlation between nAch and success:
  • + nAch → + success
  • (-) nAch → + failure

• Education, independence, self-confidence, self-esteem (people with high nAch features).
• Competitive society — media can perpetuate the value of achievement.
