One such project at the laboratory required a complicated turbine design for mixing chemicals . There must be ' <' and '> ' ordering operators having the same left and right input datatypes as the mergejoinable operator itself . These operators must be named ' <' and '> ' ; you do not have any choice in the matter , since there is no provision for specifying them explicitly . She designed systems from the initial determination of the system type and size to the selection and specification of each of the system components and the system layout . The over-pressurization helps prevent infiltration and protects the occupants in the event of a chemical release and possible air contamination . Then , the functions must all have distinct C names but they can be declared with the same SQL names ( as long as their argument types differ , of course ) . Fluor Corporation is now one of the world 's largest , publicly owned engineering , procurement , construction , and maintenance services organizations .
