However, nitrous oxide emissions were deduced from the electron balance, cathode
coulumbic efficiency and Tafel plots. Bioelectrochemical evolution of the biocathode was related to the denitrification nature (sequential reaction steps from NO3- to N-2, through NO2- and N2O as stable intermediates) and was supported by the Tafel plots.
CONCLUSIONThe bioremediation of nitrate-polluted groundwater with a MFC biocathode is feasible. (c) 2012 Society of Chemical Industry”
“Objective-To assess the diagnostic utility of transurethral cystoscopic biopsy in dogs with histologically confirmed transitional cell carcinoma (TCC) of the urinary bladder and urethra.
Design-Retrospective case series.
Animals-92 dogs
with histologically confirmed TCC.
Procedures-Information on sex, breed, neuter status, buy 3-MA body weight, tumor location, biopsy method, number of biopsy procedures, experience level of clinician performing biopsy, and quality of biopsy sample was obtained from medical records. The association of variables with likelihood of achieving a diagnostic-quality biopsy sample was evaluated by use of logistic regression.
Results-If used as the initial biopsy method, cystoscopic biopsy samples were of diagnostic quality in 65% of male dogs and 96% of female dogs with histologically confirmed TCC. Cystoscopic biopsy samples were significantly more likely to be of diagnostic quality in female dogs than in male dogs.
Conclusions and Clinical Relevance-Cystoscopic biopsy Temsirolimus molecular weight is an effective method
to obtain biopsy samples in dogs with TCC of the bladder and urethra. Cystoscopy is more find more likely to produce a diagnostic-quality biopsy sample in female dogs with TCC than in male dogs with TCC. Cystoscopy should be considered as a primary means of biopsy in male and female dogs with masses of the urinary bladder or urethra. (J Am Vet Med Assoc 2011;239:350-356)”
“Interlayer exchange couplings were examined for Co2FeAl0.5Si0.5 (CFAS)/Cr/CFAS trilayered films grown on MgO (001) single crystal and thermally oxidized Si substrates. The films were (001) epitaxial on MgO and (110) textured polycrystalline on SiO2.Strong exchange couplings were observed for the films with the 1.5 nm thick Cr spacer layer. A 90 degrees coupling is dominant in the (001) epitaxial film. In contrast, an antiparallel coupling exists in the polycrystalline one. The relationship of interlayer couplings with the structure is discussed. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3072018]“
“BACKGROUNDIn this work, photochemical treatment (UV/H2O2) of a municipal secondary effluent was studied to assess its suitability for preparing water for reuse. Ten water reuse criteria obtained from the legislation of eight countries were used as indicators of water quality.
