Crown

A former coin in the United Kingdom equal in value to five shillings, or 1/4 of one British pound. The last crown was minted in 1965. Following decimalization in 1971, a 25-pence coin was minted to replace the crown. Informally, crowns were called dollars, recalling the time when one pound was worth four U.S. dollars.

Summary of variance analysis of plant height (H), stem diameter (SD), leaf dry mass (LDM), stem dry mass (SDM), shoot dry mass (SHDM), principal root dry mass (PRDM), secondary root dry mass (SRDM), total root dry mass (TRDM), total dry mass (TDM), shoot height: diameter ratio (SHDR), shoot: root ratio (SRR) and quality index of Dickson (DQI) of mangosteen seedlings grown on different substrates at 240 DAP.
Short dental roots resulting in unfavorable crown to root ratios can affect the prognosis of teeth (Holtta et al, 2004) and increases the periapical stress.
Shoot to root ratios were arcsine transformed before analysis; Tukey's studentized range test (HSD) was used to determine significant differences between means when compared by population and by treatment at P < 0.05 in SYSTAT v.10.2 (Wilkinson, 2001).
Increased retention and stability of the overden- ture can be achieved by lengthening the vertical wall contact between abutment teeth and the denture base but in periodontally compromised teeth it is not possible because only by preparing the abutment into dome shaped can improve the crown root ratio which will reduce mobility.
Even though the crown root ratio was unfavorable, a decision was made to retain the coronal fragment.
Significantly the higher shoot and root length, their fresh and dry weights, shoot: root ratio, total plant biomass was obtained when 100 and 150 mg kg-1 Si applied from Ca-silicate.
2, the square root ratio of the respective maximum out-of-band gains given in decibels is [(89 dB/71 dB).sup.1/2] [approximately equal to] 1.12, which is close to the observed 1.22 factor of increase in NGD.
