The seminal papers in the field of root-discriminant bounds are those of Odlyzko and Martinet.
A mean relative absolute error of 5% for field capacity of surface layer, 10% for field capacity of root zone, 15% for wilting point of surface layer and root zone, and 20% for soil depth can be obtained in favorable conditions.
For simplification, the growth field of the root apex was considered here as a one dimensional vector field (the main axis) due to the slenderness of the root and the anisotropy of its growth and to the lack of shear growth (this is similar to the rod approximation in the beam theory of solid mechanics [ 24]).
a, Bright-field microscopy of root cross-sections of an early phloem marker (PEAR1), a marker of differentiating phloem expressed in phloem-companion cells (APL), an early xylem marker (AtHB8) and a marker specific to differentiating xylem vessels (VND6) at different times after secondary growth activation.
This is an important field of study, rooted in the efficient market hypothesis (EMH), which stresses that prices should incorporate all available information and former prices cannot be used to predict returns (Malkiel and Fama, 1970).
This paper presents a modelling approach to assess the field level impact of root exudates on crop PUE.
The initial approach followed a sun-drenched trail through aspen groves and fields of balsam root, past views of snowy spires, until we climbed a couple of thousand feet and the trail all but disappeared, turning into a dirt-and-boulder-strewn slope, and it was time to scramble.
This was assumed to be a box whose volume is the average of the ones calculated for each field (cubic root of the product of the volume of each field).
Examples are familiar one-syllable words in the field of scatology (Greek root skat, "dung") describing disposal of bodily wastes, now most often expressed in a shout after stubbing your toe in the dark.
None of the dentists reported using rubber dam routinely to isolate the field of operation during root canal therapy.
Most games are sold out largely because Wrigley is an old-fashioned "field of dreams" for fans who root, root, root for the "Cubbies".
