摘要:
A compound of formula (I): ##STR1## where E is oxygen or sulphur; A is CR.sup.3 or N where R.sup.3 is hydrogen or hydrocarbyl; D completes a 5 or 6-membered non-aromatic heterocyclic ring which optionally contains additional heteroatoms selected from oxygen, nitrogen or sulphur and which is optionally substituted by an optionally substituted lower hydrocarbyl group, or an optionally substituted heteroaryl group; R.sup.1 and R.sup.2 are each independently hydrogen; optionally substituted lower hydrocarbyl, or optionally substituted heteroaryl, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are attached, form a heterocyclic ring; Z represents halogen optionally substituted lower hydrocarbyl, optionally substituted lower hydocarbyloxy, optionally substituted lower hydrocarbylthio, hydrocarbylsulphinyl or hydrocarbylsulphonyl, cyano, nitro, CHO, NHOH, ONR.sup.7' R.sup.7", SF.sub.5 ; CO (optionally substituted lower hydrocarbyl), acylamino, COOR.sup.7, SO.sub.2 NR.sup.8 R.sup.9, CONR.sup.10 R.sup.11, OR.sup.12 or NR.sup.13 R.sup.14 where R.sup.7, R.sup.7', R.sup.7", R.sup.8, R.sup.9, R.sup.10 and R.sup.11 are independently hydrogen or lower hydrocarbyl; R.sup.12 is hydrogen; SO.sub.2 lower hydrocarbyl or COR.sup.15 ; R.sup.13 and R.sup.14 are independently lower hydrocarbyl, lower hydrocarbyloxy or a group R.sup.12 ; R.sup.15 is OR.sup.16, NR.sup.17 R.sup.18, hydrogen or lower hydrocarbyl; R.sup.16 is lower hydrocarbyl; R.sup.17 and R.sup.18 are independently hydrogen or lower hydrocarbyl; provided that when there are two or more substituents Z, they may be the same or different; and m is 0 or an integer from 1 to 5.

摘要:
A process of selectively killing or severely damaging oats growing in cereal crops other than oats by applying to the crop area, in an amount sufficient to kill or severely damage the oats, but insufficient to damage the cereal crop substantially, a 4,4'-bipyridylium diquaternary salt.
摘要:
An object is examined by detecting properties of the object at different times within a space formed by spatial frequencies. This is done such that temporally consecutive recordings are made in overlapping regions of the spatial frequency space and also in regions of the spatial frequency space that differ from one another.
