These studies have illuminated the nature of interactions between DNA and proteins, the constraints within which the cellular machinery operates, and the forces created by DNA-dependent motors. The physical properties of the DNA double helix are unlike those of any other natural or synthetic polymer...
The ratio of the applied forces was taken to be Fx:Fy = 1:−1. The coefficient of friction between the side of the gauge section of the specimen and the compression platen was 0.05. The material was assumed to follow the von Mises yield criterion with the work-hardening characteristics ...
The predicted applied loads and horizontal compression forces against central joints presented in Fig. 7.27 reveal the beneficial impact of additional bottom and top reinforcement in respective EMJ-B-1.48/0.59 and EMJ-B-1.19/0.89 to the enhancement of CAA capacities in comparison with EMJ-B-1.19/...

How is a graph of voltage versus time obtained on the oscilloscope screen? What is meant by a power diagram? How do you calculate % difference for work and energy? Write the equation definition of Translational Equilibrium. How do you calculate the actual mechanical advantage of a lever?
To raise the pole from the position shown, the tension {eq}T {/eq} in the cable must supply a moment about {eq}O {/eq} of {eq}72 \ kNm. {/eq} Determine the magnitude of {eq}T {/eq}. Torque of a Force: By app...

However, during evaporation of water from a biofilm, these same physical surface–air interface forces will likely work in favour of the biofilm, forming a protective, concentrating physical force around the biofilm rather than a disruptive force. As with microbial metabolic studies in general, the...
Fig. 1. a) R/FRC cross section; b) strain profile; c) stress diagram in FRC, internal forces, and external bending moment. The NtcFRC in Fig. 1c represents the total tensile capacity of the FRC, including the component corresponding to the tension-stiffening effect of the FRC under the...
