John Batts Banbury, Oxfordshire Andrew MacGregor (Letters, 15 March) raises the question of loose-bottomed baking tins when calculating quantities with water rather than mathematics.
Computer software packages are also becoming more available that can assist in calculating quantities, such as crystal sizes, vessel volumes, energy dissipation and flow patterns, supersaturation and temperature profiles, as wll as power input.
Mathematics plays a role in many aspects of life, such as cooking (ratios and proportions), sports (scorekeeping), home upkeep (calculating quantities of building materials and paint, budgeting), and others.
The deformation overlap, which is a numerically calculated quantity through displacement analysis at the initial contact, is defined as the piled region of a contact tooth pair due to the elastic deformation.
With this as background, our study used molecular markers to analyse the mating system and to calculate quantity of effective N. alpina donors in a clonal seed orchard.
For the pseudo-second-order kinetic, there was close agreement between the calculated quantity adsorbed at equilibrium (q cal), and experimentally determined quantity adsorbed at equilibrium (q exp), across the initial RhB concentrations considered (Table 3).
(D) if said calculated quantity does not exceed a prescribed minimum quantity of successfully received e-mails, repeating steps (A -(C) until said calculated quantity exceeds said prescribed minimum quantity.
This method uses standard curves of known starting material concentrations to calculate quantity of cDNA.
Absorbance was read at 260 nm to calculate quantity and the 260 280 nm ratio was measured to calculate purity.
Nevertheless, we also wish to demonstrate how optimisation can be considered and so also calculate the total expected mortality in primary and secondary affected regions as a simply described and calculated quantity for optimisation.
Appropriate suspensions (with calculated quantity of graphene (0.024 0.484 g) in THF (7.5 cm) were obtained in the process of sonication at 50 °C for 30 min in ELMASONIC P ultrasonic bath at a frequency of 80 kHz.
