C(2)H(4)/CO/H(2) reaction is investigated on Rh/SiO(2) model catalyst surfaces. Kinetic reactivity and infrared spectroscopic measurements are investigated as a function of Rh particle size under near atmospheric reaction conditions. Results show that propionaldehyde turnover frequency (TOF) (CO insertion pathway) exhibits a maximum activity near = 2.5 nm. Polarization modulation infrare...

Clinicians sometimes are confronted with the challenge of transfusing haemorrhaging Rhesus (Rh) D negative patients with Rh D positive blood to save their lives. There are concerns about alloimmunization and future haemolytic disease of the newborn in women of the reproductive age. Another fear is transfusion reaction if they receive another Rh D positive blood in future. We present a 32-year-o...

Using a small-core single-mode fiber (SCSMF), a novel relative humidity (RH) sensor based on an SMF28-SCSMF-SMF28 fiber structure was proposed in this paper. By depositing a humidity sensitive material, such as poly (ethylene oxide) (PEO) on the bare SCSMF fiber, the proposed structure can act as an RH sensor with high sensitivity. Experiments demonstrated that the proposed RH sensor with PEO c...

By ALEXANDER S. WIENER, M.D., F.A.C.P., RAFFAELE NAPPI, M.D. AND EVE B. GORDON I N THE PRECEDING PAPER’ our methods for performing Rh antibody titrations were described in detail, with special reference to the precautions taken to insure objective and reproducible results. Using these technics, it was shown that pregnancies with Rh-negative fetuses and the birth of Rh-negative babies have no si...

In fall of 2009, several mass strandings of Humboldt squid (Dosidicus gigas) occurred on Vancouver Island (49°7 60N 125°54 0W). Morphological dissections coupled with DNA barcoding of stomach contents revealed Sardinops sagax (PaciWc sardine) and Clupea pallasii (PaciWc herring) as their primary prey. Plastic nurdles, Wshing line, bull kelp, eelgrass, and a guillemot feather were also discovere...

98 Mexican Indians were tested for the blood properties A-B-O, A(1)-A(2), M-N, P, Rh'-Rh''-Rh(0)-rh, and Hr. Of the 98 Indians, 90.8 per cent belonged to group 0, 6.1 per cent belonged to A(1), and 3.1 per cent to group B. There were 61.2 per cent of type M, 3.1 per cent of type N, and 35.7 per cent of type MN. Of the 95 Mexican Indians tested with anti-P serum, 21.1 per cent were found to lack...

We, NMFS, have completed a comprehensive status review of the Southeast Alaska Distinct Population Segment (DPS) of Pacific herring (Clupea pallasii) under the Endangered Species Act (ESA). Based upon the best scientific and commercial data available, we conclude that listing the Southeast Alaska DPS of Pacific herring is not warranted at this time. We also announce the availability of the stat...

The physiological mechanism of functional constipation (FC) includes defecatory disorders and delayed colon transit. About 18% to 68% constipated patients may have rectal hyposensitivity (RH). We performed this study to investigate the association between RH and functional defecatory disorder (FDD) as well as that between RH and delayed colon transit in FC patients.A total of 218 FC patients we...

Red blood cell deficiency of Rh proteins is associated with morphologic and functional abnormalities of erythrocytes and with a chronic hemolytic anemia of varying severity. Rh-deficiency may be the result of homozygosity either for a silent allele at the RH locus (Rhnull amorph type) or for a recessive inhibitor gene(s) at an autosomal locus unlinked to RH locus (Rhnull regulator and Rhmod). I...
