A process for the estimation of mass concentration of iodine in table salt supplemented by potassium iodate comprises the preparation of aqueous solution of table salt supplemented by potassium iodate. Then iodate-ion is reduced with sodium thiosulphate to ion iodide. Iodide-ions are oxidized with ...
The mass-spring model was first proposed for the earthquake response analysis of immersed tunnels based on shaking table model tests and earthquake observations of an immersed tunnel in Japan (Okamoto & Tamura, 1973). It relies on the assumptions that (1) the natural period of the ground is ...

What is the mass in grams of a single molecule of water, H2O? A cube of NaCl has a mass of 135 g. This salt was dissoved in 1 Liter of water. How much is the salt concentration, in grams per milliliter (g/mL)? What is the molarity of a solution that contains 130 grams of C...
(feeding on materials such as clay and chalk). For example, the seasonal mass migration of Mormon crickets (Anabrus simplex) across western North America in search of two nutrients: protein and salt. Researchers have shown that the crickets stop walking once their demand for protein is met (...
c, d, Agarose-gel-electrophoretic characterization of the self-cleavage reaction of a pseudogene using the DNAzyme cassette architecture shown in b; c, self-cleavage at different salt concentrations at 37 °C; d, self-cleavage at different temperatures at salt concentrations of 5 mM MgCl2 ...
The Enrichment Factor (EF) solution (Lawson and Winchester, 1979; Sturges, 1989) is a variant of the Tracer solution that compares ratios of chemical concentrations in the atmosphere to the same ratios in a reference material, such as average crustal composition or sea salt for a region. These...
We used supercritical carbon dioxide as the mobile phase because it has low polarity and is effective for the analysis of hydrophobic compounds9,10. Multiple reaction monitoring (MRM) transitions were selected based on a charged fragment corresponding to diacylglycerol (DAG) (Supplementary Table 1)....
(Fig.1; Table3) (a literature search was conducted using general search terms including Imaging Mass Spectrometry, Mass Spectrometric Imaging, Mass Spectrometry Imaging and Plant Imaging, results were then filtered for plant based articles). A dramatic acceleration (doubling) in the rate of ...
