Nitrogen Isotope Separation by Ion Exchange Chromatography
Enriched stable isotopes of many elements have been widely used in many aspects and such isotopes have been primarily used as the tracer for agricultural and biochemical studies and the availability of the isotopically labeled compounds have been now extensively increasing. Chemical exchange separation of isotopes is based on the equilibrium fractionation of isotopes between two phases, ion exc...
متن کاملNitrogen Transformations in the Tobacco Float Tobacco System
In order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of Urmia in 2010. The experiment was done as factorial trail based on randomized complete block design (CRBD) with four replications. The levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...

متن کاملSpeaker Separation and Tracking System
Replicating human hearing in electronics under the constraints of using only twomicrophones (even withmore than two speakers) and the user carrying the device at all times (i.e., mobile device weighing less than 100 g) is nontrivial. Our novel contribution in this area is a two-microphone system that incorporates both blind source separation and speaker tracking. This system handles more than t...
متن کاملFlow injection conductometric system with gas diffusion separation for the determination of Kjeldahl nitrogen in milk and chicken meat.
A simple flow injection (FI) conductometric system with gas diffusion separation was developed for the determination of Kjeldahl nitrogen (or proteins) in milk and chicken meat. The sample was digested according to the Kjeldahl standard method and the digest was diluted and directly injected into the donor stream consisting of 4M NaOH. In alkaline medium, ammonium was converted to ammonia, whic...
