Abstract Advanced antimicrobial biomaterials for wound healing applications are an active field of research their potential in addressing severe and infected wounds overcoming the threat resistance. Beta-glucans have been used preparation these materials bioactive properties, but very little progress has made so far producing biomedical devices entirely beta-glucans integration with effective a...

martindale proved that under some conditions every multiplicative isomorphism between two rings is additive. in this paper, we extend this theorem to a larger class of mappings and conclude that every multiplicative $(alpha, beta)-$derivation is additive.

Parallel to the experimental work on the study of nuclear decay schemes and other problems in nuclear spectroscopy, continuous work has been devoted to the perfection of the spectroscopic instruments. Much of the earlier experimental investigations could be performed with rather simple and sometimes even crude techniques but such cases are becoming increasingly rare. The remaining problems gene...

The assignments of the 1H, 15N, 13CO and 13C resonances of recombinant human basic fibroblast growth factor (FGF-2), a protein comprising of 154 residues and with a molecular mass of 17.2 kDa, is presented based on a series of three-dimensional triple-resonance heteronuclear NMR experiments. These studies employ uniformly labeled 15N- and 15N-/13C-labeled FGF-2 with an isotope incorporation > 9...

Current estimates of the normalized accretion rates quasars (L/L_Edd), rely on measuring velocity widths broad optical-UV emission lines (e.g., H$\beta$ and Mg II $\lambda2800$). However, such tend to be weak or inaccessible in most distant quasars, leading increasing uncertainty L/L_Edd at $z > 6$. Utilizing a carefully selected sample 53 radio-quiet that have C IV $\lambda1549$ spectroscopy a...

Miscut surfaces of layered crystals can exhibit a stair-like sequence terraces having periodic variation in their atomic structure. For hexagonal close-packed and related crystal structures with an {\alpha}{\beta}{\alpha}{\beta} stacking sequence, there have been long-standing questions regarding how the differences adatom attachment kinetics at steps separating affect fractional coverage {\alp...

We review the work carried out in the X13 R&D Straight Section of the NSLS X-Ray Ring on small gap in-vacuum undulators (IVUNs). Then we discuss: (1) plans to replace the pure permanent magnet undulator in X13 by a hybrid design providing stronger magnetic fields, enhancing the tunability of the device; (2) plans to install hybrid IVUNs in the two RF straights of the X-Ray Ring, increasing the ...

The procedure followed by the Nuclear Metrology Laboratory (LMN), at the Nuclear and Energy Research Institute (IPEN), for the primary standardization of (177)Lu is described. This radionuclide is widely used in radiopharmacy due to its convenient half-life and emitted beta ray energies. The (177)Lu solution was supplied during an international comparison sponsored by BIPM in 2009 and the prima...
