concentration test a test of renal function based on the patient's ability to concentrate urine; see also fishberg concentration test. Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health, Seventh Edition. © 2003 by Saunders, an imprint of Elsevier, Inc. All rights...
The strength of acid in an alkylation unit is controlled by a system using a signal corresponding to the anticipated demand on the acid by the reaction of olefin and isoparaffin in the presence of the acid. The reaction weakens the acid so that it is necessary to replace some of the ...
[translate] aIn contrast,the ionization of acetic acid is only 1 to 3 depending on the concentration of the acid,so it is a week acid 相反,乙酸的电离只是1到3根据酸的集中,因此它是星期酸[translate]
The hydronium ion concentration of an aqueous solution of 0.381 M caffeine (a weak base with the formula C8H10N4O2) is ... H3O+ = M. Weak Acid and Weak Base: Weak acids and weak bases different from strong acids and bases in that they d...
Higher concentration of essential fatty acids (PUFAs), eicosapentaenoic and docosahexaenoic acid are mostly found in seafoods which make them susceptible to lipid oxidation which lead to degradation in quality and undesirable off flavour and smell. Grape pomace phenolics were found effective on fish pro...
The N content was determined after sulfuric acid digestion using the Nessler colorimetric method; P by molecular absorption spectrophotometry; K by flame photometry; S by sulfate turbidimetry. The contents of Ca, Mg, Fe, Zn, Mn, and Cu were determined by atomic absorption spectrophotometry, and ...
Humic acid (HA) is a common contaminant in groundwater and surface water. Many efforts were made to use high efficiency low cost materials to remove HA from water. In this study, the effectiveness of using palygorskite to adsorb low concentrations of HA was investigated as a function of the...
46. Kumar and co-workers have previously reported the generation of 4–5 mers and 12–24 mers from lauric acid along a non-fibril formation pathway22. More importantly, using carbon chain lengths of C9-C12 fatty acids (FAs), they established that below (non-micellar), near (pseudo-...
"Activation" apparently involves appearance of new carrier proteins rather than gain in energy coupling to existing carriers, since studies of amino acid interaction during influx, heteroexchange and inhibi- tion of energy metabolism indicate a specific initial lack of rele- vant carriers. However "...
Sulfuric acid (12 mL, 98%, w/w) was added to the SSP solution (2 mL), which was then immediately cooled with ice water. Show abstract Effects of calcium treatment and low temperature storage on cell wall polysaccharide nanostructures and quality of postharvest apricot (Prunus armeniaca) 2017...
