Numerical Methods for Solving Equations

1.1 Solving an Algebraic System

This code defines a function f(V) and then solves the system f([x,y,z]) = [x,y,z] to find its fixed points using the algsys command.

faux(x,y,z) := [(x^2)/2 + 1/3, x+y+z/4, x^2-y^2+(z^2)/4];
f(V) := faux(V[1], V[2], V[3]);

ecus : f([x,y,z]) - [x,y,z];
algsys(ecus, [x,y,z]), numer;

1.2 Fixed-Point Iteration Method

This block implements the fixed-point iteration method. It starts with an initial guess (seed) and iteratively applies the function f until the norm of the difference between successive iterations is smaller than a given tolerance (10-14).

nor(V) := sqrt(V.V);
fpprec:100;

Leptin and Adipose Tissue

Leptin is released from adipose tissue when mass is high. It travels through the blood to the arcuate nucleus, binds to neuronal cells, and activates the JAK-STAT pathway. This increases gene expression of POMC, which produces alpha-MSH (a neurotransmitter). Alpha-MSH reaches neurons connected to adipose tissue, releasing norepinephrine. Norepinephrine binds to beta-adrenergic receptors on adipose tissue, promoting an increase (via the G-protein coupled receptor pathway and activation of PKA). This leads to upregulation of UCP1 expression and... Continue reading "Metabolic Pathways and Liposome Drug Delivery" »

Chemical Equilibrium & Enthalpy Changes

Le Chatelier's Principle & Equilibrium Constant (Kc)

  • If a reaction is endothermic, an increase in temperature will shift the equilibrium to the right-hand side (products) to decrease the temperature.
  • Position of Equilibrium: Describes how far a reaction has proceeded and the proportion of products to reactants in the mixture.
  • Equilibrium Constant (Kc): The constant for an equilibrium system, expressed in terms of concentrations (mol dm-3) at a given temperature.
  • Kc Formula: Kc = [Products] / [Reactants]
    • Example (Haber Process): N2(g) + 3H2(g) ⇌ 2NH3(g)
    • Units for Haber Process Kc: (mol dm-3)-2 or mol-2 dm6
  • Temperature Effects on Kc/Kp:
    • For an exothermic reaction, an increase in temperature decreases Kc/

Allegra Byron's Early Life in Venice

Allegra Byron lived with her father, Lord Byron, in a large house called the Palazzo Mocenigo. However, Lord Byron eventually realized that it was not a suitable home for a child. He entrusted Allegra to an English family in Venice. Allegra stayed in Venice for eight months with different families. When Allegra was four years old, Byron sent her to a convent school near Ravenna. Allegra was often cold and lonely there.
