spec: Herbicide effect is enhanced when 1 ) Cirsium arvense roots are weakened during the growing season by herbicide treatment , crop competition , or frequent mowing or tilling ; and 2 ) new shoots are stimulated to grow . Pulled plants should be removed from site if at all possible , especially if flowers are present . '' There is no one industry experience from the past that quite fits the biosciences , so we need a kaleidoscopic view to mix and match from other fields , `` said Mack Center Research Director Paul Schoemaker . The flowers are pollinated by a wide variety of insects , including beetles , bees , and especially small flies . Just weeks ago , in late February , The Guardian newspaper said that Alec Jeffreys , a geneticist at Leicester University and the inventor of genetic fingerprinting , considered the study to be very poorly structured . A feature of the standards is the assignment of expiration dates as a way to define expectations as to how long a desktop system will be viable in regard to support of SITA-compliant systems . The former is actually more of a cooperative venture in which the college 's film and video collection is jointly housed with that of the state library . Rollins , the former Bain partner who signed on with Dell in 1996 and who became its president in 2001 , has played a major role in designing the strategies that the company has used to attain its position as the top computer manufacturer in the world . Sponge cakes are often turned upside-down to cool so that the air pockets do not collapse during cooling . Some of this spent fuel is so old that it is no longer `` self-protecting '' ( highly radioactive ) and thus poses a potential security risk . I then passed out for the rest of the weekend . Hand-cutting of individual plants or mowing of larger infestations should be conducted prior to seed set and must be repeated until the starch reserves in the roots are exhausted . However , even faults to well grounded transmission towers or substation structures can result in hazardous voltages . A. Basically a readability study is you take random samplings from a text and you look at how many words are in a sentence , how many syllables are in each word , and you plug them in , and they - - it 's a formula , and they spit it back to you , basically , on how - - what the level of the reading is , whether it 's a third-grade level , you know , fifth-grade level , twelfth-grade level . The goal of these standards is to define desktop computers that will be guaranteed , at any given time , to run any SITA-compliant system . Root fragments from a single young plant can produce over 900 shoots when the roots are cut into 10 cm fragments ( Nadeau and Vanden Born 1989 ) , as typically occurs with discing . P. Br. at 8-10 . However , this approach is not appropriate for all species . These roots are also more likely to be winterkilled , since disced fields accumulate less snow cover than undisced fields , and soil temperatures are lower ( Cirsium arvense roots are injured at -2 degrees C and killed at -8 degrees C ; Schimming and Messersmith 1988 ) .
