Sir,?In reply to your correspondent Adolphe Passanha, M. A., who asks if it is usual to obtain a green colour when dispensing Antipyrin and Sp. Eth. Nit. together, I may perhaps be allowed to state such is the usual result, unless the Sp. Eth. Nit. is freely diluted and added last, which even then will not always prevent this characteristic colour. See Squire, 15th Edition, p. 73. Tests.?The aq...

The optical charge pumping method (OCPM) for extracting the spatial distribution of the interface state density (Nit) is proposed. By combining the concept of local threshold voltage in CPM and the drain current generated by the trapped electrons excited from the interface states to the conduction band by incident photons, the Nit is successfully extracted in the SONOS-type flash memory cell tr...

S. typhimurium nit mutants are defective in nitrogen assimilation, despite having normal levels of assimilatory enzymes. Complementation, enzyme assays, and genetic mapping show that nit is nadE. We present evidence that ammonia, not glutamine, is the physiological substrate for eubacterial NAD synthetases and that low activity completely accounts for the mutant phenotype.

This thesis has assessed the prevalence of spontaneous tinnitus (ST), noiseinduced tinnitus (NIT) and temporary threshold shift (TTS) in children and adolescents as well as investigated some of the audiometric, medical and psychological characteristics of young subjects with tinnitus. Additionally, long-term effects of noise exposure were examined in relation to ST, NIT and TTS. The methods emp...

Vegetative compatibility groups (VCGs) are determined for many fungi to test for the ability of fungal isolates to undergo heterokaryon formation. In several fungal plant pathogens, isolates belonging to a VCG have been shown to share significantly higher genetic similarity than those of different VCGs. In this study we sought to examine the relationship between VCG and genetic similarity of an...

Abstract Nitrification is a major pathway of N 2 O production in aerobic soils. Measurements and model simulations nitrification associated emission are challenging. Here we innovatively integrated data mining machine learning to predict rate ( R <mml...

Organic and inorganic nitrogen play important roles in plant nutrition. However, how the coapplication of organic affects root growth, metabolism, soil content is still unclear. Plant shoot uptake were studied maize (Zea mays L.) through pot experiments with different treatments, including NH4+ -N (Amm), NO3− (Nit), + (Amm Nit), glutamate-N Nit Glu), glycine-N Gly). The results show that treate...
