Measuring drag without a force transducer: a terminal velocity assay
1. Organisms live surrounded by air or water, which exert drag on an organism when moving. These forces are significant ecologically because they can affect organisms’ distribution, behaviour or dispersal. 2. Appropriate techniques for measuring or estimating these forces vary greatly depending on the magnitude of the forces and the flow pattern of the moving fluid (air or water; both gases and...
متن کاملHow Terminal Is Terminal Velocity?
Several years ago the authors of the present piece wrote a MONTHLY article [1] describing the velocity dependence of aerodynamic drag. Recently, a science reporter for the Guardian newspaper, who found this reference, solicited our help in writing an article about how a 102-year-old woman from Turin could fall out of a fourth floor window and survive [2]. In particular, the reporter wanted to k...
متن کاملWind dispersal capacity of pine seeds and the evolution of different seed dispersal modes in pines
Pine seed mass is isometrically related to samara shape among smaller seeded pines (< 165 mg), but not when larger seeds are included (putative bird-dispersed pines excluded). Among the largest pine seeds samara length declines with increases in seed mass. Consequently, disc-loading increases and dispersal capacity declines at an accelerating rate with increases in seed mass. The acceleration i...

15 صفحه اولThe essential light chain N-terminal extension alters force and fiber kinetics in mouse cardiac muscle.
The functional significance of the actin-binding region at the N terminus of the cardiac myosin essential light chain (ELC) remains elusive. In a previous experiment, the endogenous ventricular ELC was replaced with a protein containing a 10-amino acid deletion at positions 5-14 (ELC1vDelta5-14, referred to as 1vDelta5-14), a region that interacts with actin. 1vDelta5-14 mice showed no discerna...
