Redundant mechanisms for anaphase chromosome movements: crane-fly spermatocyte spindles normally use actin filaments but also can function without them

Protoplasma, 2005
Actin inhibitors block or slow anaphase chromosome movements in crane-fly spermatocytes, but stopping of movement is only temporary; we assumed that cells adapt to loss of actin by switching to mechanism(s) involving only microtubules. To test this, we produced actin-filament-free spindles: we added latrunculin B during prometaphase, 9-80 min before ...

Experimental study of wear of gears of the portal crane movement mechanism

Hoisting and transport equipment
Portal cranes play a crucial role in transshipment activities within maritime and riverine environments. As an essential component of the operational chain, the efficiency of port operations is closely tied to their dependable and uninterrupted functioning.

PARAMETRIC OPTIMIZATION OF FREQUENCY-CONTROLLED START-UP OF DYNAMIC SYSTEM "TROLLEY-LOAD" OF TOWER CRANE TROLLEY MOVEMENT MECHANISM

Naukovì Dopovìdì Nacìonalʹnogo Unìversitetu Bìoresursiv ì Prirodokoristuvannâ Ukraïni
In the scientific article, a scientific and applied problem is solved, which allows to minimize the dynamic and energy parameters of the frequency-controlled drive of the dynamic "cart-load" system of the tower crane flight change mechanism during the transient start-up mode.
