Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches
Chemistry – A European Journal, EarlyView.We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system
Deep Underground Science and Engineering, EarlyView.The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

Multiple-cracked fatigue crack growth by BEM
Computational Mechanics, 1995The dual boundary element method is applied to the two-dimensional linear elastic analysis of fatigue problem of multiple-cracked body. For each crack, the traction integral equation is applied on one surface of the crack, while the usual displacement integral equation is used simultaneously on the other. General multiple crack growth problem is solved

Fatigue in materials subjected to repeated cyclic loading can be defined as a progressive failure due to crack initiation (stage I), crack growth (stage II), and crack propagation (stage III) or instability stage. For instance, crack initiation of crack-free solids may be characterized by fatigue crack nuclei due to dislocation motion, which generates ...

A fatigue crack growth threshold
Engineering Fracture Mechanics, 1992Abstract Fatigue crack growth (FCG) threshold has been determined on Ti6A14V, Al 7475-T7351, quenched and tempered steel 24CrMo4 as well as on the Ni-base alloys Inconel 617 and Nicrofer 5219 Nb. The main objective of the studies was to prove the transferability of the experimentally determined FCG threshold to service type fatigue loading.

As discussed in Chapter 2, the traditional approach to estimate the total life of a structural part is to use the S—N diagram (alternating stress, S, versus the total number of cycles to failure, N). This diagram can be constructed by conducting several laboratory tests on standard specimens subjected to low amplitude fluctuating loads simulating the ...
