BACKGROUND Except for the ribosomal protein L12 (rplL), ribosomal proteins are present as one copy per ribosome; L12 (rplL) is unusual because it is present as four copies per ribosome. Thus, the strategies used by Mycobacterium fortuitum to regulate ribosomal protein synthesis were investigated, including evaluations of the rates of chain elongations of 16S rRNA, rplL and ribosomal protein S12...

The commercial steel was processed by three different Q&P heat treatments and kinds of steels with microstructures mechanical properties were obtained. Among them, two samples contain bainite ferrite matrix, fresh martensite retained austenite, while the other possesses tempered austenite. Comparing content austenite in these samples, highest volume fraction obtained sample matrix a higher ...

We have recently shown that in monkey passive extraocular muscles the force induced by a stretch does not depend on the entire length history, but to a great extent is only a function of the last elongation applied. This led us to conclude that Fung's quasi-linear viscoelastic (QLV) model, and more general nonlinear models based on a single convolution integral, cannot faithfully mimic passive ...

Inconel 718 was successfully processed by multi-pass high-pressure sliding (MP-HPS) for production of ultrafine-grained structures in rods with upsized dimensions. An (UFG) structure an average grain size ~ 140 nm developed through rotation 45°. Tensile testing at 1073 K initial strain rate 2x10-2 s−1 led to superplastic elongations more than 400%. A relation is established between hardness and...

A novel variable temperature rolling (VTR) and annealing process was conducted on a metastable austenitic stainless steel. Strain softening occurred during tensile straining in both cold rolled cryogenic rolled-annealed steels, leading to low uniform elongations of only 2-3%. In contrast, thanks the dual-phase heterogeneous lamellar structure achieved via VTR process, ultra-high strength over 1...

Sarcomere lengths have been a crucial outcome measure for understanding and explaining basic muscle properties and muscle function. Sarcomere lengths for a given muscle are typically measured at a single spot, often in the mid-belly of the muscle, and at a given muscle length. It is then assumed implicitly that the sarcomere length measured at this single spot represents the sarcomere lengths a...

We present a detailed theoretical investigation of the electronic structure and optical properties of InAs nanocrystals at the transition from spheres to rods. Using a semiempirical pseudopotential approach, we predict that, despite the qualitative similarity of both intra- and inter-band optical spectra, for NCs with R>15 Å even slight elongations should result in shifts of the order of hundre...
