Stock Valuation, Market Mechanics, and Risk Management
Understanding Stock Valuation
A stock is worth the present value of its expected future income. Using the dividend growth model, that future income is primarily future dividends. The formula is: Stock Value = Present Value of Future Dividends.
Calculating Total Return
A stock provides returns in two ways:
- Dividend Yield: Cash paid by the company while you own the stock.
- Capital Gains Yield: Profit earned if the stock price increases.
Total Return = Dividend Yield + Capital Gains Yield
Example: If the beginning

Understanding Coronaviruses
A coronavirus is not just one single bug; it is actually a large family of viruses. They get their name because under a microscope, they look like they are wearing a spiked crown—“corona” means crown in Latin. While many coronaviruses only cause mild illnesses like the common cold, a few rare types can jump from animals to humans and cause severe respiratory infections.
Key Types of Coronaviruses
Most of the time, humans contract mild “community” coronaviruses that cause

Diagnosis (Adults)
- First-line tests:
- Blood eosinophils OR FeNO
- Diagnostic thresholds:
- FeNO ≥ 50 ppb OR raised eosinophils → asthma diagnosed
- If unclear:
- Bronchodilator reversibility (BDR)
- ↑ FEV1 ≥ 12%
- Bronchodilator reversibility (BDR)
- If still unclear:
- PEF variability (2 weeks)
- If still suspected but tests negative:
- Bronchial challenge test (specialist)
Severity (Acute Asthma)
- Severe:
- PEFR 33–50%
- RR > 25
- Pulse > 110
- Unable to complete sentences
- Life-threatening:
- PEFR < 33%
- Confusion
- Exhaustion

Database Normalization and Management Principles
Database Normalization and 3rd Normal Form
Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. It divides large tables into smaller related tables.
Objectives of Normalization
- Remove duplicate data.
- Eliminate insertion anomalies.
- Eliminate deletion anomalies.
- Eliminate update anomalies.
- Improve data consistency.
3rd Normal Form (3NF)
A table is in 3NF if:
- It is already in 2NF.
- No transitive dependency exists.
- Non-key attributes depend only on the primary
