We use fully-resolved simulations to predict the force and torque acting on a long cylinder or fiber inclined with respect incoming flow. Results obtained in viscous regime are compared predictions of slender-body theory, possibly incorporating finite-inertia corrections. Numerical results used build approximate models for valid from creeping-flow conditions up upper limit stationary inertial r...

A new species of Bumba Pérez-Miles, Bonaldo & Miglio, 2014 is described and illustrated. This comprises the first record genus for Bolivia. paunaka sp. nov. differs from other in black longitudinal band on abdomen, long slender embolus palpal bulb thin subapical spine retrolateral branch tibial apophysis. Females additionally differ spermathecal morphology. Finally, a distribution map all known...

Classically, an abelian group $G$ is said to be slender if every homomorphism from the countable product $\mathbb Z^{\mathbb N}\mathbb N$ factors through projection some finite Z^n$. Various authors have proposed ge

African trypanosomes cause devastating disease in sub-Saharan Africa in humans and livestock. The parasite lives extracellularly within the bloodstream of mammalian hosts and is transmitted by blood-feeding tsetse flies. In the blood, trypanosomes exhibit two developmental forms: the slender form and the stumpy form. The slender form proliferates in the bloodstream, establishes the parasite num...
