The phrase “law at the edge of empire,” used by historian Peter Hoffer, really shows how messy and complicated the treaties between the British and Indigenous peoples were during colonization. Hoffer meant that these treaties sat in a space where British law met Indigenous law, and neither side saw things the same way. The British wanted treaties to bring Indigenous nations into their legal system, but Indigenous peoples already had their own laws, customs, and governments. Because of that,
Problem checks: SAT ∈ NP because a Boolean assignment is a polynomial-size certificate and we can evaluate the formula in polynomial time.
Reduction (construction):
Given a circuit made only of NAND gates (each gate has two inputs which are either an input wire, a constant T/F, or an earlier gate output), make one Boolean variable for each circuit input and one variable for the output of each gate. For each gate z = NAND(a,b) add CNF clauses that force z to equal ¬(a ∧
Lectures:
Lecture 7: Economic Frameworks to Study the World Food Problem - Demand, Supply, Elasticity. The Demand Curve follows the Law of Demand: as price falls, quantity demanded rises, causing a downward slope. This is due to Diminishing Marginal Utility (less satisfaction from extra units) and Heterogeneity in Demand (different people have different willingness to pay). The entire demand curve can shift based on changes in consumer incomes, tastes, or the prices of other goods. The Supply Curve...
💧 WATER CHEMISTRY CHEAT
1. Sources of Water
Source Description Characteristics
Surface Water Rivers, lakes, ponds, reservoirs Contains suspended, colloidal & dissolved impurities
Ground Water Wells, springs, borewells Contains dissolved salts (hardness) but less organic matter
Rain Water Condensed atmospheric water vapour Purest natural form but may contain dissolved gases like CO₂, SO₂
Sea Water Oceanic water Contains ~3.5% salts; not fit for domestic use

how nutrients generally move among organisms, origin of mineral N: Atmospheric N₂ is converted into mineral forms (NH₄⁺, NO₃⁻) by: Biological fixation (by bacteria in roots or soil) Lightning fixation Industrial fixation (fertilizers); N cycling: i. Plant uptake and incorporation (mineral → organic N) ii. Resorption before leaf fall (retranslocating nutrients) iii. Decomposition of litterfall (organic → mineral N)
importance of nutrient resorption: Plants withdraw nutrients (like
Unit 1. Q 1: Difference between speculation, investment, and gambling. Describe the process of investment management. Also tell about difference between financial investments versus real investments. Also, first of all meanings of investments.
Investment plays a crucial role in the economic development of a country as well as in the personal financial growth of individuals. Every person or business aims to utilize their funds efficiently to earn future returns. In simple terms, investment
CHAPTER 4 OVERVIEW – Protein Structure & Function
Proteins are at the center of all biological processes.
They catalyze reactions, regulate pathways, transport molecules, and form most of the structural framework of cells.
Core Principle: Structure → Function.
Key Historical Milestones:
