All investigations were based on 10 concrete mixture designs containing variable volume fractions and maximum sizes of natural coarse aggregate for maximum exposure period of 170 days.
The immunosensor design involves the covalent immobilization of the antigen onto carboxylic-modified magnetic beads (HOOC-MBs) activated with N- 3-dimethylaminopropyl -N′-ethylcarbodiimide (EDC) and N-hydroxysulfosuccinimide (sulfo-NHS), and further incubation in a mixture solution containing variable concentrations of the antigen and a fixed concentration of an HRP-labeled detection antibody.
The swelling properties of so-called 'balanced' microgel particles (i.e. containing the same number of positive and negative monomers in the initial mixture), but containing variable amounts of the crosslinking monomer, have been investigated as a function of ionic strength using photon correlation spectroscopy.
Mixtures of NH4NO3Ca(NO3)2 with a molar ratio 0.844/0.156 containing variable amounts of water (from 0 to 1.2 moles per mol of salt) were used as a solvent.
To check the accuracy of the proposed method, several synthetic mixtures containing the analytes in variable amounts were prepared and analyzed in triplicate using the HPLC-RI method.
In this study, total deformation of each sample was calculated using a newly developed equation containing variables of mixture characteristics.
The reaction mixture (300 μl) contained variable concentrations of Pyr2C, 50 mM Tris HCl buffer, pH 7.6, 0.16 mM NAD(P H, and enzyme.
These differences likely reflect the fact that malignant tissue samples contain variable mixtures of both normal and transformed cells while normal samples contain only normal cells.
Although 5XFAD dystrophic neurites generally could be classified as either Type I or Type II, we observed that some dystrophies contained variable mixtures of vesicular structures found in both subtypes, suggesting that a continuum of neuritic morphologies might exist between Type I and Type II neurites.
Nevertheless, some form of Ld/ Lo coexistence appears to be a general feature of mixtures containing equimolar amounts of SM and Chol, with variable amounts of PC (Fig. 1, dashed line).
