Contribution of nitrification and denitrification to N2O emissions from urine patches [PDF]

, 2007
Urine deposition by grazing livestock causes an immediate increase in nitrous oxide (N2O) emissions, but the responsible mechanisms are not well understood. A nitrogen-15 (15N) labelling study was conducted in an organic grass-clover sward to examine the

Methods for the determination of submicro quantities of total nitrogen, ammonia, amino nitrogen, amides, peptides, adenylic acid, and nitrates [PDF]

, 1939
In 1935 one of us described micromethods for ammonia, urea, total nitrogen, uric acid, creatinine, and allantoin (1). These methods are adapted for the analysis of 1 to 2 ml. aliquots of dilute solutions, e.g. 0.1 mg. per cent of ammonia or urea, and for

Comparative Proteomic Profiling of Clinical Klebsiella pneumoniae Strains and the Corresponding Outer Membrane Vesicles

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
ABSTRACT Klebsiella pneumoniae (K. pneumoniae) has become a global threat due to the convergence of carbapenem resistance and hypervirulence. Outer membrane vesicles (OMVs) play important roles in bacterial pathogenicity, yet their functional coordination with strains remains unclear.
