Rh is one of the most important noble metals for industrial applications. A major fraction of Rh is used as a catalyst for emission control in automotive catalytic converters because of its unparalleled activity toward NOx reduction. However, Rh is a rare and extremely expensive element; thus, the development of Rh alternative composed of abundant elements is desirable. Pd and Ru are located at...

The layer-averaged magnetic moments of Co and Rh have been measured in sputter deposited Co/Rh ~001! multilayer thin films using the x-ray magnetic circular dichroism. The Rh moments were measured at both the L and M absorption edges, where we find that the Rh moment decreases as a function of increasing Rh layer thickness (tRh). The decline of the layer-averaged Rh moment is well described in ...

Red blood cell (RBC) transfusion is a key treatment of patients with sickle cell disease (SCD) but remains complicated by RBC immunization. In the present study, we evaluated the effects of antigen matching for Rh D, C, and E, and K and transfusion from African American donors in 182 patients with SCD. Overall, 71 (58%) chronic and 9 (15%) episodically transfused patients were alloimmunized. Fi...

The effects of various chemical and enzymatic treatments on the biological activity of porcine luteinizing hormone-releasing hormone (LH-RH) are described. This experiment was performed before the elucidation of the structure of LH-RH. LH-RH activity was abolished by the following endopeptidases: chymotrypsin, subtilisin, papain, and thermolysin, but not by pepsin or trypsin. Exopeptidases d...

The Merrifield solid-phase peptide synthesis technique has been adapted to the synthesis of homo- and heterometallic metal−organic complex arrays (MOCAs). A terpyridine-appended and Fmoc-protected L-tyrosine derivative was metalated with Pt(II), Rh(III), or Ru(II) ions in solution and sequentially coupled at the surface of functionalized polymeric resin to give a metal complex triad (Rh−Pt−Ru),...

1. The theory of six allelic genes is reviewed, using the new improved nomenclature, and data are summarized regarding the distributions of the eight Rh types among white and negro individuals in New York City. 2. Results are presented of tests for property Hr in a series of 239 white individuals and 49 negroes. Statistical analysis of these data yields results supporting Race and Taylor's hypo...

The title compound, [Rh(C(5)H(7)O(2))(C(20)H(32)NP)(CO)], features an acetyl-acetonate-chelated Rh(I) cation coordinated by one P [Rh-P = 2.2525 (7) Å], one carbonyl C [Rh-C = 1.792 (3) Å] and two O [Rh-O = 2.0582 (17) and 2.0912 (18) Å] atoms in a slightly distorted square-planar geometry. Mol-ecules are packed in positions of least steric hindrance, with the phosphane ligands positioned above...

Billingham et al.' reported that mice and chickens injected as embryos with cells from other strains acquired a persistent tolerance to later skin grafts from the donor strains. It seemed possible to us that a similar, but naturally acquired, tolerance might be in part responsible for the variation in response of Rh-negative persons exposed to the Rh antigens.2 The hypothesis to be tested was t...

Patients with right hemisphere (RH) lesions often display a spatial bias in attention towards the ipsilesional hemifield. The behavioural manifestations of this spatial bias are typically interpreted as reflecting increased or enhanced attention for stimuli within the 'intact' ipsilesional field, and impaired attentional functioning within the contralesional field. In the healthy brain, goal-dr...

Increasing dependence on Information and Communication Technologies (ICT) especially the Internet in Industrial Control Systems (ICS) has made these systems primary target of cyber-attacks. As ICS are extensively used Critical Infrastructures (CI), this makes CI more vulnerable to cyber-attacks their protection becomes an important issue. On other hand, cyberattacks can exploit not only softwar...
