The application of magnetic resonance spectroscopy at progressively smaller length scales may eventually permit 'chemical imaging' of spins at the surfaces of materials and biological complexes. In particular, the negatively charged nitrogen-vacancy (NV(-)) centre in diamond has been exploited as an optical transducer for nanoscale nuclear magnetic resonance. However, the spectra of detected sp...

Chemical studies of the blood and urine of four dogs following pyloric obstruction are reported. The observations of other workers that a fall in chlorides and a rise in CO(2)-combining power of the plasma occur, are confirmed. There is also a marked rise in the non-protein nitrogen of the blood, consisting mainly of urea nitrogen and undetermined nitrogen. The fall in chlorides is not due to t...

Background & Aim:Peppermint known for its healing properties is a plant from the Labiatae family. Currently, different rates of nitrogenous fertilizers are used in production of peppermint while there is no precise information available about how much of nitrogen fertilizer is the optimum rate for this plant. The main purpose of this research was to evaluate the response of pep...

In all of its known connections nitrogen retains a valence shell electron count of eight therefore satisfying the golden rule of chemistry - the octet rule. Despite the diversity of nitrogen chemistry (with oxidation states ranging from + 5 to -3), and despite numerous efforts, compounds containing nitrogen with a higher electron count (hypervalent nitrogen) remain elusive and are yet to be syn...

A study was conducted to evaluate the correlation between selected physico-chemical parameters of water and their effects on growth of Rainbow trout (Oncorhynchus mykiss) in raceway system in the area of Sarab Gerdu, Iran. The samples were collected from twenty raceways (270- day old fish, surface area 55m2 flow rate 150 ls-1 total production 15 T). Physico-chemical parameters were the fluctuat...

Trenholm for their supportive efforts throughout this learning experience. I give special thanks to Dr. Shober, my committee chair, for her encouragement, direction and commitment. I am also appreciative to Gitta Shurberg for her assistance in the field as well as laboratory. Abstract. Urban soils have highly variable chemical, physical, and biological properties compared to undisturbed natural...
