E NG. 2 MODULE 1.2: INTRODUCTION TO CONTROLS • Introductory topics on control systems • Focus on distributed control systems – particularly relevant to industrial automation. • More lectures on control systems will follow. • Learning outcomes for Module 1.2: Introduction to Controls • Describe the components of a control system. • Define three types of variables associated with a control...
Glycolipids are least abundant lipids with a backbone made of sphingosine and contains two tails usually both saturated and heads with polar sugar groups ALWAYS found on the non-cytosolic leaflet (signaling and recognition using these happens in extracellular) Sterols are Second most abundant lipids with a rigid ring structured backbone with one short tail and a small head group that is found on both leaflets unsym. distribution of these different types of lipids in the biological bilayer (PS with
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
2. Impurities in Water

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
