This study documents a series of time゛veraged gas species measurements made along the centerline of a 30 cm methanol pool fire steadily burning in a quiescent environment. All gas species measurements were obtained using a gas chromatograph/mass spectrometer system (GC/MS). Measurements were made...
The values for WISOM were also similar to those of the methanol soluble organic matter in other locations of southeast Asia, which ranged from 3 to 104,23,58,59,60. The AAE values of HP-WSOM from this study should have large uncertainty. From the wavelength of 300 nm to onward, the ...
17). The core structure of PnGH1 contained eight parallelβ-strands surrounded by eight helices forming the (β/α)8barrel fold as a substrate-binding pocket (Fig.3c). In addition, several salt bridges between Asp/Glu residues and Lys/Arg...
Methylamine is a weak Lewis base. It is also known as methanamine, MeNH2, methyl ammonia, methyl amine, and aminomethane. Methylamine is most commonly encountered in pure form as a colorless gas, although it's also found as a liquid in solution with ethanol, methanol, water, or tetrahydrofur...
Each glycolipid preparation was dissolved in HPLC grade methanol (Merck, Gillingham, UK) at a concentration of 1 mg mL−1. The conditions of operation for the HPLC-MS were set as follows: Mobile phase A for the LC device was Elga HPLC grade water (Merck, Gillingham, UK) whereas mobile...
The mobile phase consisted of two components: solvent A, acetonitrile:methanol:tris buffer (0.1 M, pH 8) (83:2:15, v:v:v), and solvent B, methanol:ethyl acetate (68:32, v:v). The pigments were eluted using a linear gradient from 100% A to 100% B for the first 7 min, ...

for dairy protein ingredients (Glass and Hedrick, 1977;Herwig et al., 2011). The calcium content is expected to be low in LAC-P as a consequence of the selective precipitation approach used to enrich α-lac in WPC, as calcium-binding salts are often added to modify α-lac structure from...
gamboges and is therefore an ideal chemical marker for quality control. However, during the isolation and purification processes, gambogic acid can be transformed by the nucleophilic addition of methanol to the olefinic bond at C-10 when stored in methanol solution at room temperature (Figure3) [...
