Federation of Petroleum and Chemical Workers ( IFPCW ) did not come about and after the IFPCW ceased to exist the ICF extended its activities to the energy sector , renaming itself International Federation of Chemical , Energy and General Workers ' Unions ( ICEF ) in 1976 ; associated with the International Confederation of Free Trade Unions ( ICFTU ) and became one of the largest International Trade Secretariats ( ITS ) ; in 1984 the membership of its affiliated unions surpassed six million workers , represented within the ICEF by separate sections for the energy , chemical , rubber , glass , ceramic , paper , cement and other industries ; coordinates the strategy and activities of affiliated unions in different countries ; tries to counter-balance the power of multinational companies , the importance of which was especially stressed by its general secretary Charles Levinson ; concerned with labour conditions , health and safety , industrial democracy and supports efforts of trade union organization in non-democratic countries . Engineered Processes and Material : The synthesis , characterization , and processing of metallic , ceramic , organic , and composite materials ; advanced materials and processes tailored for specific applications . Coverage of both fine and decorative art : painting , sculpture , drawings , prints , photographs , textiles , costumes , jewelry , ceramics , furniture , glass , books and manuscripts , archaeological finds , and more . Such support would have included production facilities for food , ceramics , and building materials ( gypsum mortar , stone , wood , and metal tools ) ; storage facilities for food , fuel , and other supplies ; and housing for workmen , their families , and priests responsible for services in pyramid temples . However , virus are much smaller than bacteria and would not be captured by a mechanical filter ( carbon block , ceramic , etc. ) . The selection may be performed at any stage of the design process from concept to detail ; and the materials may be from any class : metals , polymers , ceramics , natural materials and composites . In particular , Gordon focuses on so-called strong materials , such as metals , wood , ceramics , glass , and bone .
