"It is so rewarding to see science so valued and enjoyed by both the teachers and the students." | For more information on Phiz Labs, go to www.ogdentrust.com/school-partnerships/phiz-labs Details of their P3L
programme for this year will be coming soon.
When connecting P point perpendicularly to line H, the intersecting point was designated as PH (P1H, P2H, P3H, P4H and P5H); the horizontal perpendicular line connecting P point to line L created an intersection point PL (P1L, P2L, P3L
, P4L and P5L) (Fig.
A subsequent study described both early P3E and late P3L
in response to correct deviance detection in frontal and parietal cortical areas in rats .
The analyzed samples have [summation][C.sub.27]-[C.sub.29] regular steranes/[summation][C.sub.29]-[C.sub.33] 17[alpha]-hopanes ratios from 0.33 to 0.85 and gammacerane/[C.sub.30] 17[alpha], 21[beta]-hopane ratios from 0.12 to 0.37 with slightly higher values in P3l
source rocks (Table 3).
Table 10 shows how the model-predictions change when the most sensitive parameter, p3l
in the entrapment function, is varied by [+ or -]5% from its reference value of 3.20 X [10.sup.-4].
