It took some time for U.S. law and politics to connect itself to the global economy. For years, the country was divided over whether those connections were necessary, and, then, which government agency has the obligation to maintain the connection. It came down to the US Supreme Court, who made conclusions that influence international economics to the present day. We'll take a look at the key cases, all of which are still controversial decades later. Since the U.S. dollar remains the currency of choice for world business today, quite a few of America's international business partners know these ageing Supreme Court rulings backwards-and-forwards as well. Knowledge is power, especially when billions of dollars are at stake around the world.... Continue reading "The Influence of Military Power on Foreign Policy and International Economics" »

ATP and Cellular Work

ATP energy helps cells perform three types of work:

1. Chemical: Assists chemical reactions.
2. Transport: Performs transport work.
3. Mechanical: Moves muscle fibers, for example.

Enzyme Assistance

How do enzymes assist in chemical reactions?

1. Enzymes provide an active site specific to a substrate

The following examples demonstrate complex SQL techniques using conditional logic (IF, CASE), subqueries, variable assignment, and string manipulation to analyze geographical and economic data stored in tables like Pais (Country), Ciudad (City), and LenguaPais (Country Language).

1. Independence Year Formatting for African Countries

This query retrieves the name of countries in Africa and formats their independence year (AnyIndep) to display whether it was B.C. (a.C.) or A.D. (d.C.).

        CONCAT(AnyIndep,' d.C'),
        IF(AnyIndep < 0,
            CONCAT(ABS(AnyIndep),' a.C'),
            'N/A')) AS 'Año de Independencia'
