Such compounds have the general formula OnE(OH)m, and include sulfuric acid, O2S(OH)2, sulfurous acid, OS(OH)2, nitric acid, O2NOH, perchloric acid, O3ClOH, aluminum hydroxide, Al(OH)3, calcium hydroxide, Ca(OH)2, and potassium hydroxide, KOH: If the central atom, E, has a low...
For two series X1 and X2, with respective arithmetic means X¯1 and X¯1 and respective numbers of observations n1 and n2, the arithmetic mean X¯ of the series X that is the union of X1 and X2 is given by the following formula: X¯=n1X¯1+n2X¯2n1+n2. 3. The arith...
SNA15896. Based on their HR-MS data, the molecular formulae of the SW-163 derivatives were determined (3: C52H60N10O14S2;8) 4: C53H62N10O14S2; 5: C54H64N10O14S2;8) 6: C55H66N10O14S2; 7: C56H68- N10O14S2). These data show that the difference among these homologs ...
to the presence of these new products, in particular aluminum oxides and layered double zinc–aluminum hydroxides (ZnAl–LDH) with general formula ZnxAly(A)m(OH)n⋅zH2O (where A is an anion, in studies of atmospheric corrosion often it is carbonate) [1], [2], [3], [4], [15]. ...
reported a positive, non-linear relationship of kidney function with 24 h urinary Ca in a subgroup of 319 nephropathic patients with glomerular filtration ranging from <15 to ≥90 mL/min × 1.73 m2 as assessed by creatinine clearance predicted using the Cockcroft-Gault formula [3]. In 2019,...
For the degummed SF, we calculated the value ofIc=0.86 from FTIR, as compared with 0.66 [24], 0.72, and 0.84 for Mulberry silk, regenerated SF film [43], and electrospun SF mats, respectively [44]. The average molar mass that we calculated from the viscosity of SF aqueous solutions in...
Body mass index (BMI) was calculated from the average of height and weight measurements using the formula: weight in kilograms divided by height in meters squared. 2.3. EAT5 Food Frequency Questionnaire The EAT5 FFQ was designed to be quantitative, interviewer administered and to rank 5-year ...
The correlation between quantitation of proteins by label-free LC-MS/MS (variable LF) and peak intensities of proteins observed by MALDI-MSI (variable MSI) was calculated using the formula: Correlation index (LF,MSI) = ∑(LF−LF) ∑(LF−LF)2 (MSI−MSI) ∑(MSI−MSI )2 . ...
the tip leakage mass flow rate in BSSS was higher, while the BSSM cases were lower than the BRSS case; (2) The deviations of the BSSS and BSSM cases from the BRSS case both increased when the rotation rate increased; (3) The experimental data for BSSM was better than that for BSSS...
[19,35]. In general, the crystalline phases obtained from clinoptilolite through solid-state transformations have often revealed compositions that deviate from the ideal formulae [36,37]. Due to the scarce quantity of POL in the materials, the refinement of its Cs-occupancy was not allowed ...
