This study presents an innovative design of a microtab system for aerodynamic load control on horizontal-axis wind-turbine rotors. Microtabs are small devices located near the trailing edge of the rotor blades and enable a rapid increase or decrease of the lift force through deployment of the tabs on the pressure or suction side of the airfoil, respectively. The new system has been designed to ...
Vascular homoeostasis, development and disease critically depend on the regulation of endothelial cell-cell junctions. Here we uncover a new role for the F-BAR protein pacsin2 in the control of VE-cadherin-based endothelial adhesion. Pacsin2 concentrates at focal adherens junctions (FAJs) that are experiencing unbalanced actomyosin-based pulling. FAJs move in response to differences in local cy...
High resolution OVRO CO 1-0 observations of the inner kpc of the M51-companion NGC 5195 reveal the presence of a kpc-sized bar, or possibly an inclined disk with a two armed spiral, at the center of the optical bar. The molecular mass of the feature is 2.7 × 10 M⊙, half of which is within a radius of 250 pc. The resulting gas surface density of 10 M⊙ pc −2 is typical for starbursts. However, th...
ANALYSIS OF SPHERICAL FIVE-BAR HINGED MANIPULATOR WITH TWO DEGREES OF FREEDOM AND DWELLS OF OUTPUT LINK. N. Davitashvili. “Problems of Mechanics”. Tbilisi, 2015, No 1(58), pp. 5-11, (Engl.). Is stated the kinematic study of spherical five-bar manipulator with two degrees of freedom. Are determined the positions, velocities and accelerations of output links, their points and gripper. The manipul...
We have performed for the first time in the literature a 2D structural analysis on the barred lenticular and face–on galaxies NGC 4608 and NGC 5701. The results indicate that these galaxies either have never had large disks or their disks were almost completely destroyed by their strong bars, due to secular evolution processes. We discuss these surprising conclusions checking for signs of secul...
Membrane scission is essential for intracellular trafficking. While BAR domain proteins such as endophilin have been reported in dynamin-independent scission of tubular membrane necks, the cutting mechanism has yet to be deciphered. Here, we combine a theoretical model, in vitro, and in vivo experiments revealing how protein scaffolds may cut tubular membranes. We demonstrate that the protein s...
In kinematics, a framework is called overconstrained if its continuous flexibility is caused by particular dimensions; in the generic case, a framework of this type is rigid. Famous examples of overconstrained structures are the Bricard octahedra, the Bennett isogram, the Grünbaum framework, Bottema's 16-bar mechanism, Chasles' body-bar framework, Burmester's focal mechanism or flexible quad me...
