SN2 , SN1 , E2 , & E1: Substitution and Elimination Reactions
2), acetonitrile ( CH 3 CN ) o Protic solvents (e g H 2 O or ROH) deactivate nucleophile by hydrogen bonding but can be used in some case • Nucleophilic Substitution Reactions (SN2 and SN1) replace a eav inggroup wth anucleophile ( Nu:or -) • Elimination Reactions (E2 and E1) generate a double bond by loss of " A+ " and " B: - "
Hazard Control using the “Hierarchy of Control”
1 Elimination ↓ 2 Substitution ↓ 3 Isolation ↓ 4 Engineering ↓ 5 Administration ↓ 6 Personal Protective Equipment (PPE) Elimination As the title suggests, this control measure involves eliminating or removing the risk in its entirety For example: • Risk: High levels of manual handling when loading and unloading glassware onto
Notes:’Solving’Systems’using’Elimination’
Elimination ’ To solve a system using elimination: Step 1 ) Look at each variable Both coefficients in front of x OR y need to be the same, one positive and one negative If this is not the case, you need to use multiplication to make the coefficients the same Step 2 ) Add the systems together (One letter should disappear/eliminate) Step 3 )
Elimination with Matrices - MIT OpenCourseWare
Elimination with matrices Method of Elimination Elimination is the technique most commonly used by computer software to solve systems of linear equations It finds a solution x to Ax = b whenever the matrix A is invertible In the example used in class, ⎡ ⎤ ⎡ ⎤ 1 2 1 2 A = ⎣ 3 8 1 ⎦ and b = ⎣ 12 ⎦ 0 4 1 2
OFFICER ELIMINATIONS: THE LEGAL PROCESS
III Reasons for Elimination (AR 600- 8-24, para 4-2) a Substandard performance of duty b Misconduct, moral or professional dereliction, or in the interest of national security c Derogatory information contained in the officer’s records combined with other known deficiencies IV

Solve each system by elimination 1) −4 x − 2y = −12 4x + 8y = −24 2) 4x + 8y = 20 −4x + 2y = −30 3) x − y = 11 2x + y = 19 4) −6x + 5y = 1 6x + 4y
Lecture 2: Dominated strategies and their elimination
Lecture 2: Dominated strategies and their elimination Let us consider a 2-player game, the players being named Robert (the Row player) and Collin (the Column player) Each of the players has a number of strategies at his disposal In the examples in lecture 1 the number and the nature of strategies were the
NTC Module 4 Digestion and Elimination
2 Secretion–Water, acid, buffers, enzymes 3 Mixing/Propulsion–Moving the food through the GI tract ateanddescribe the testpoints for theDigestionFunctional Evaluation 4 Digestion– Breakdown of food 5 6 Absorption– Passage of nutrients into the blood and lymph Defecation– Elimination of the “leftovers”
Two Compartment Body Model and Vd Terms
2 The point of equilibrium is unique in that there is one overall elimination rate constant, ke, just as we saw in the one-compartment model This k e may be written in terms of the microconstants (k 10, k 12, k 21) used in the two compartment model This allows us to write vd drw
