Iron is a vital element for plant and microbial growth; yet, the major portion of iron in soils form (oxi-)hydroxides with limited bioavailability, resulting decreased crop yield quality. In response to deficiency, soil microorganisms produce siderophores that transform insoluble into soluble plants can use. The abundance activity siderophore-producing bacteria (SPB) might be used as biological...

Abstract The potential for aggression is inherent in social interaction, and strategies to reduce the costs of are ubiquitous among group-living animals. One strategy employed by lower-ranking individuals a variety species production subordination signals, which formal signals that communicate signaler’s inferior status relative recipient signal. Here, we report results our investigations into ...

The study was undertaken to determine the potential of general cross combinations in sugarcane, obtained by open pollinating the female parents, to generate variants for Brix (percent total soluble solids) content and frequency distribution pattern of variants, hence generated. Using Brix (an indicator of sucrose content) as selection criterion, 819 ratooned seedlings raised from five general c...

Phage P22 produces antirepressor protein early after infection from a transcript initiated at the Pant promoter. After the first few minutes of infection, transcription from Pant is repressed by a protein encoded by the arc gene. Antirepressor is not produced late in infection, even though the antirepressor gene, ant, is transcribed from the late operon promoter Plate. We describe the isolation...

We recorded 'pant-hoot' vocalizations from male chimpanzees, Pan troglodytes, housed in two captive facilities in the U.S.A., Lion Country Safari and North Carolina Zoological Park. Acoustic analysis revealed significant differences between the two groups in the temporal patterning of the calls. Because the captive males within each group are from diverse origins, within-group similarity in pan...

BACKGROUND The purpose of this study was to investigate the validity and reliability evidences of the Omron BI pedometer, which could count steps taken even when worn at different locations on the body. METHODS Forty (20 males and 20 females) adults were recruited to walk wearing 5 sets, 1 set at a time, of 10 BI pedometers during testing, 1 each at 10 different locations. For comparison, the...

Birdsong is a prime example of acoustically sophisticated vocal behaviour, but its complexity has evolved mainly through sexual selection to attract mates and repel sexual rivals. In contrast, non-human primate calls often mediate complex social interactions, but are generally regarded as acoustically simple. Here, we examine arguably the most complex call in great ape vocal communication, the ...

Scoring 895 out of a possible 1000 points, the Campanile, Rice yearbook, has won All American Honor rating, the highest honor attainable by college or university yearbooks. This ra t ing was given by the scholastic editor of the Department of Journalism a t the University of Minnesota, a f t e r an analysis of the Campanile of 1928. Four other rat ings are given on this method of scoring. They ...
