Read the perlre manpage to help you decide which of / s and / m ( or both ) you might want to use : / s allows dot to include newline , and / m allows caret and dollar to match next to a newline , not just at the end of the string . Airline flows may very well be a prime example of transnational inter-city relations , but no amount of data manipulation can prevent that such statistics have a fairly limited conceptual relation to world city – formation ( see , for instance , Beaverstock et al ., 2000a , b and Derudder and Witlox , 2005b ) . These subjects were exposed at 0 and 25 mg / m ( 3 ) VOC-contaminated air . Offices with smoking occupants show a range of average nicotine concentrations similar to that of residences ( 2 to 10 ug / m ( 3 ) ) , but with considerably higher maximum values . Three hetus are sobhana ( beautiful ) ; they are : alobha ( greedlessness or generosity ) , adosa ( non-hate or lovingkindness ) and amoha ( panna or wisdom ) . Grade 12 uses many of the concepts developed in grades 9 , 10 , and 11 : worldview ( 9 ) ( 11 ) ; paradigms ( 9 ) ( 10 ) ; social contract ( 10 ) ; ideology ( 10 ) ( 11 ) ; and integration ( 11 ) are some of the more important examples . ETS-RSP concentrations in offices with smoking occupants on average appear to be about the same as residences ( 18 to 95 ug / m ( 3 ) ) . ETS-nicotine exposures of the average worker appear to be of the order of 5 to 10 micrograms per cubic meter ( ug / m ( 3 ) ) , and for the most-exposed workers , 50 to 100 ug / m ( 3 ) ) . These include latency ( very important in on-line gaming ) ; burstiness ( important for file-sharing applications ) ; mobility and the ability to interwork with other platforms .
