21. Eminences vary in size in different individuals, are occasionally unsymmetrical , and are especially prominent in young skulls. 22. Ordinary boxplots do not fare well with skew distributions, since they label the longer unsymmetrical tails as outliers. 23. Either a second fender panel must be contacted or the fender cannot compress to much in an unsymmetrical fashion. 24. Mixed ( or unsymmetrical ) acid anhydrides, such as acetic formic anhydride ( see below ), are known. 25. It is a two-stage launch vehicle with storable propellants, consisting of Nitrogen Tetroxide and Unsymmetrical Dimethyl Hydrazine. 26. The Bodva flows on the eastern edge of a karstic rock system, therefore it has an unsymmetrical drainage pattern. 27. Palladium-Catalyzed Cross-Coupling of Aryl Chlorides and Triflates with Sodium Cyanate : A Practical Synthesis of Unsymmetrical Ureas 28. If both alkyl groups in a ketone are the same then the ketone is said to be symmetrical, otherwise unsymmetrical . 29. Like other members of the Universal Rocket family, the Proton-K was fuelled by Unsymmetrical dimethylhydrazine and nitrogen tetroxide. 30. There are four symmetrical isomers of DBT which can be made, or ten isomers in total if unsymmetrical substitution is used.
