The dinitroaniline herbicides (particularly trifluralin) have been globally used in many crops for selective grass weed control. Consequently, trifluralin resistance has been documented in several important crop weed species and has recently reached a level of concern in Australian Lolium rigidum populations. Here, we report novel mutations in the L. rigidum α-tubulin gene which confer resistan...

We have obtained long-slit spectra of NGC 253 in the J, H, K, and N bands, broadband images in the J, H, and K s bands, narrowband images centered at the wavelengths of Brγ and H 2 (1,0)S(1), and imaging spectroscopy centered on [Ne II](12.8µm). We have subtracted a composite stellar spectrum from the galaxy spectrum to measure faint emission lines which otherwise would be buried in the complic...

Here, we report the isolation of 31 Acinetobacter baumannii strains producing OXA-253 in a single large Brazilian city. These strains belonged to five different sequence types (STs), including 4 STs not previously associated with blaOXA-253 In all strains, the blaOXA-253 gene was located in a plasmid within a genetic environment similar to what was found previously in Brazil and Italy. The repo...

Abstract Effect leachate on soil quality in Jos is expected because the disposal sites continues to be major route of infiltration as it affects area. Six selected and normal were collected local auger at depth range 1.5 3.0 m with distances 1.0, 1.5,3.0m. The study aim identifies effect, using PAST statistical software excel analyze results. Particle size sand has higher percentage increase po...

Our objective was to alter the substrate specificity of purine nucleoside phosphorylase such that it would catalyse the phosphorolysis of 6-aminopurine nucleosides. We modified both Asn-243 and Lys-244 in order to promote the acceptance of the C6-amino group of adenosine. The Asn-243-Asp substitution resulted in an 8-fold increase in K(m) for inosine from 58 to 484 microM and a 1000-fold decrea...

We enumerate three classes of non-medial quasigroups of order 243 = 3 up to isomorphism. There are 17004 non-medial trimedial quasigroups of order 243 (extending the work of Kepka, Bénéteau and Lacaze), 92 non-medial distributive quasigroups of order 243 (extending the work of Kepka and Němec), and 6 non-medial distributive Mendelsohn quasigroups of order 243 (extending the work of Donovan, Gri...

were accepted as indicative of definite acute myocardial infarction (AMI). ST-T changes regardless of characteristics were not accepted as evidence of AMI. Operative mortality was 11% (27/253) with 59% (10/17) of those autopsied having AMI. Autopsy findings showed no false positives by ECG. Of survivors, 15% (33/220) had AMI. Another 2% (five) developed leftbundle conduction abnormalities and w...
