The present versions of Bernoulli’s method use quotients of successive sums of powers of the roots to extract dominant roots. These algorithms can be ameliorated considerably through two new basic results, namely, a recursion formula for the quotients just mentioned and a representation of the minimal absolute value of the roots only using the quotients calculated earlier. In the case of (nearl...

The aims of this study were to investigate genotypic variations in root traits at phytomer level of wheat varieties and for recommending a few root traits as selection parameters in future breeding programs. Two separate experiments were conducted to measure their root traits for hydroponically grown wheat plants. In Experiment 1, main axis length, root hair density and diameter differed from p...

INTRODUCTION The aim of this in vitro study was to identify the root and canal morphology of maxillary first and second molars in Iranian population by taking and analyzing cone-beam computed tomography (CBCT) scans. METHODS AND MATERIALS Extracted maxillary first (n=125) and second (n=125) molars were collected from native Iranians and scanned by using a CBCT scanner. The number of roots and...

8 Group 1.1c Crenarchaeota are the predominating archaeal group in acidic boreal forest soils. In this 9 study we show that the detection frequency of 1.1c crenarchaeotal 16S rRNA genes increased in the 10 rhizospheres of the boreal forest trees following colonisation by the ectomycorrhizal fungus Paxillus 11 involutus. This effect was very clear in the fine roots of Pinus sylvestris, Picea abi...

Objective: To evaluate root canal configuration and morphology of premolar teeth among Saudi subpopulations using cone beam computed tomography (CBCT). Material Methods: In this retrospective cross-sectional study, CBCT images 314 patients comprising 346 maxillary 412 mandibular first (FPM) teeth, 298 387 second (SPM) were analyzed to the number roots, morphology, based on Vertucci's classifica...
