The phrase "and number of shells" is correct and usable in written English.
It can be used when discussing quantities or counts related to shells, such as in a scientific or descriptive context.
Example: "The study focused on the size and number of shells collected from the beach."
Alternatives: "and quantity of shells" or "and count of shells".
Topics covered include minimum approach in a heat exchanger, design targets, the problem table algorithm, composite curves, the pinch and its significance, minimum-utility design, network simplification, temperature cross, heat load loops and paths, number-of-shells and network area targets, and super targeting.
By carefully designing the size and number of the shells in the multilayered inclusions, the band gaps can be extended and lowered.
Then, the minimum temperature difference (ΔTmin) and the number of shells and tubes are optimized based on pinch technology.
The diameter of the ZnO hollow spheres is in the range of 0.5 to 4 μm and the number of shells in the range of 1 to 3. Figures 4d, h and5d display SEM and TEM images of the as-prepared ZnO nanoparticles. Figure 5f, g shows a high-resolution TEM (HRTEM) image recorded from the outer shell of one hollow sphere and single-shelled hollow sphere.
The cross-sectional area of the nanotube can be calculated as follows: ACNT = π/4D2 − (D − Nδ 2 where D is the difference between the external and internal tube diameter, and N is the number of shells composing the MWCNT.
Thenceforth by describing and classifying a large number of shells collected from the Italian lands, I have made all efforts to compare them with living species, mainly with those that dwell in the Adriatic and the Mediterranean and, whenever I could, I have always paralleled fossil and marine conchology.
A small number of shells and tracer bullets fired from Taliban positions arced high over the valley before hitting alliance-held positions below.
The correction factors take into account aspects of the real design, such as TEMA standards, FT correction factors, number of shells, and changes in overall heat transfer coefficients.
Throughout that time in Bosnia, the observers, who were all military officers, produced detailed daily reports, with precise counts of the exact number of shells launched and shots fired in violation of United Nations-brokered cease-fires.
Only a few wood carvings and a small number of shell and bone carvings are known.
