Young's Modulus $[Y] = [ML^{-1}T^{-2}]$.
- Force $[F] = [MLT^{-2}] \implies M = F L^{-1} T^2$
- Velocity $[V] = [LT^{-1}]$ and Acceleration $[A] = [LT^{-2}]$
- Solving for $L$ and $T$: $T = V/A$ and $L = V^2/A$.
- Substituting these into the formula for $Y$ yields $V^{-4}A^2F$.
The 'Cohabitation' in the French political system refers to:
Cohabitation occurs when the President and the Prime Minister belong to opposing political parties.
A patient is receiving heparin infusion for DVT. The nurse notes signs of overdose. Which antidote should be prepared?
Antidotes for anticoagulants:
| Anticoagulant | Antidote |
|---|---|
| Heparin (unfractionated) | Protamine sulfate |
| Warfarin | Vitamin K (phytonadione) / Fresh Frozen Plasma |
| Dabigatran (novel oral anticoagulant) | Idarucizumab |
| Rivaroxaban/Apixaban | Andexanet alfa |
Protamine sulfate is a positively charged protein that binds and neutralizes negatively charged heparin. Signs of heparin overdose: unusual bleeding, hematuria, petechiae, prolonged aPTT. Monitoring: aPTT should be 1.5–2.5 times the control value for therapeutic heparin.
Max velocity reached: $v_{\max} = \alpha t_1$
Distance in acceleration phase: $s_1 = \dfrac{1}{2}\alpha t_1^2$
Distance in deceleration phase: $s_2 = \dfrac{1}{2}v_{\max}\,t_2 = \dfrac{1}{2}\alpha t_1 t_2$
Ratio: $\dfrac{s_1}{s_2} = \dfrac{\frac{1}{2}\alpha t_1^2}{\frac{1}{2}\alpha t_1 t_2} = \mathbf{\dfrac{t_1}{t_2}}$
