The ribosomal stalk protein L12 is essential for events dependent on the GTP-binding translation factors. It has been recently shown that ribosomes from Thermus thermophilus contain a heptameric complex L10.(L12)2.(L12)2.(L12)2, rather than the conventional pentameric complex L10.(L12)2.(L12)2. Here we describe the reconstitution of the heptameric complex from purified L10 and L12 and the chara...

We prove a sharp l10(L10) decoupling for the moment curve in ℝ3. The proof involves two-step combined with new incidence estimates planks, tubes and plates.

The purpose of this study was to begin to describe the neural circuit within the abdominal ganglion that modulates renal functioning in Aplysia. We found that the previously described cholinergic neuron L10 and peptidergic left upper quadrant (LUQ) neurons have important roles in the control of the kidney. Cell L10 and a subset of the LUQ cells branch extensively within the kidney and send majo...

Type I interferons (IFNs) are essential components of the innate immune system. This study characterized the distinct IFN sensitivities of two closely related Semliki Forest virus (SFV) strains in cell culture. The virulent L10 strain was derived from the original virus isolate by propagation in mice. In contrast, the avirulent SFV strain, designated V42, was derived from an earlier passage of ...

The DNA of the transducing phage lambdarifd18 contains, among others, the genes for the ribosomal proteins L11, L1, L10, and L12 and the beta and beta' subunits of RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6). In a coupled in vitro protein-synthesis system, lambdarifd18 DNA directs the synthesis of about four to five molecules of L12 per molecule of L10. This i...

We describe x-ray diffraction and magnetic measurements of annealed MnPt and NiMn spin valves as a function of MnPt ~NiMn! film thickness. Thin films (&5 – 10 nm) are not chemically ordered and hence not antiferromagnetic, which explains the lack of exchange coupling in these films. With increasing thickness, the L10 chemical order develops ~through coexistence between fcc and L10 phases! and t...

Tetrataenite (L10-FeNi) is a promising candidate for use as permanent magnet free of rare-earth elements because its favorable properties such high magnetic anisotropy and coercivity. We report on structural Fe49Ni49Ti2 alloy after severe plastic deformation (SPD) by pressure torsion (HPT) technique. The main characteristics bulk HPT materials were determined. As result deformation, all samples...

We describe structural and magnetic measurements of polycrystalline, L10 chemical-ordered Fe(55-60)Pt(45-40) lms as a function of lm thickness (from 3 to 13 nm) and growth temperature (270 370 C). With increasing lm thickness, the coercivity increases from about 1 kOe up to 11 kOe (growth at 400C), while for increasing growth temperature, the coercivity grows from 0.2 to 6 kOe for 4.3 nm thick ...

Chemically ordered hard magnetic L10-FeNi phase of higher grade than cosmic meteorites is produced artificially. Present alloy design shortens the formation time from hundreds of millions of years for natural meteorites to less than 300 hours. Electron diffraction detects four-fold 110 superlattice reflections and a high chemical order parameter (S  0.8) for the developed L10-FeNi phase. The ma...

Titanium trialuminide coating on L10-type titanium aluminide alloys represents a valuable mean to improve oxidation resistance. Selection of L12-type titanium trialuminide alloys containing Mn as a coating material is particularly attractive because of its good ductility at room temperature and good oxidation resistance at high temperature of 1273 K. However, stability of the coated titanium tr...
