A lumped venous reservoir stores blood at a pressure determined by its volume and vascular compliance. If its inflow and outflow are $Q_{\mathrm{in}}$, $Q_{\mathrm{out}}$, the constant-compliance approximation gives $C_v{\dot{p}}_v=Q_{\mathrm{in}}-Q_{\mathrm{out}}$. It forms the filling side of a three-compartment ventricular circulation model.

Let $K$ be a convex set in a real Banach space, and let $A:K\to X^{\ast }$ be a strongly monotone operator. If $u,w\in K$ both satisfy the displayed variational inequality, testing with $v=w$ and $v=u$ respectively and adding yields $⟨Au-Aw,u-w⟩\le 0$. Strong monotonicity gives $m\Vert u-w{\Vert }^2\le 0$, hence $u=w$. This proves uniqueness whenever a solution exists.

The dense fibrous membrane separating superficial and deeper perineal structures; corresponds to the inferior layer of older triangular-ligament descriptions.

Historical anatomical model of perineal muscle and fascia; it should not be read as a universally uniform muscular sheet between two identical fascial layers.

Excess leukocytes in urine; this finding does not by itself prove bacterial infection or localise all lesions.
