The Empire of Charles V: Spain and the Holy Roman Empire
The Life of Charles V
Son of Philip the Handsome, Archduke of Austria (son of Holy Roman Emperor Maximilian I and Mary of Burgundy), and Joanna of Castile (daughter of King Ferdinand of Aragon and Queen Isabella I of Castile), Charles was born in Flanders.

E. coli Expression Systems: Host Selection, Vectors, and Industrial Titers
Escherichia coli Expression Systems
Advantages of Microbial Expression Systems
Bacterial and yeast systems share several advantages over mammalian expression systems:
- Higher growth rate and cell densities.
- Robustness at the cellular level.
- High expression levels.
- Simple cultivation and are easy to scale-up.
The selection of the appropriate expression system is determined by the characteristics of the target protein or product.

Energy & Power
• Energy: ability to do work; conserved; transforms among heat, chemical, mechanical, electrical, nuclear, etc.
• Power: rate of energy use; determines how fast work is done or energy is converted.
Units & Conversions
• calorie (cal): energy to raise 1 g water by 1 °C ~ Calorie (food Cal) = 1 kcal = 1 000 cal ~ joule (J): SI unit; 1 J = 1 kg·m²/s²
• kilowatt-hour (kWh): industrial/domestic unit; 1 kWh = 3.6 MJ ≈ 1 000 Cal
• household uses ~12 000 kWh/yr

Descriptive Measures: Center and Variability
Measures of Variation
- Standard Deviation (SD): The average measure of distance between data points and the mean (the square root of the variance). It indicates how far the data is, on average, from the mean.
- Calculation: Find the variance and take its square root.
- Coefficient of Variation (CV): Used to compare the standard deviation of two different data sets. Shown as a percentage, it measures variation relative to the mean.
- Formula: CV = (Standard Deviation
Economic Concentration Control and Capital Stock in Spanish Law
Economic Concentration Control in Spanish Law (LDC)
The Law on Defense of Competition (LDC) addresses the control of economic concentrations. The provision refers to any stable change of control of the whole or part of one or more companies resulting from a series of operations, such as a merger or the acquisition of control of the whole or part of another company.
Article 8 LDC delimits the scope of application of the Law to concentrations based on the presence of one of the two following circumstances:

Early Models of Industrial Organization
- Cournot (1838): Used mathematics to study economics, price formation with a single supplier (monopoly), and oligopoly with simultaneous quantity setting.
- Bertrand (1883): Analyzed oligopoly with simultaneous price setting.
- Stackelberg (1934): Studied sequential setting of quantities in an oligopoly.
- Hotelling (1929) and Chamberlin (1933): Introduced the concept of product differentiation.
