Extensive research shows temperature to be the primary environmental factor controlling the phyllochron, or rate of leaf appearance, of wheat (Triticum aestivum L.). Experimental results suggest that soil temperature at crown depth, rather than air temperature above the canopy, would better predict wheat leaf appearance rates. To test this hypothesis, leaf appearance in spring wheat ('Nordic') ...

The aim of this study was to define the imaging of the retrotympanum precisely by means of high-resolution CT. Based on 66 scans of petrous bones performed in 49 patients observed in an otologic department, several retrotympanic structures were studied: the pyramidal eminence, ponticulus, subiculum, chordal ridge, tympanic sinus of Proctor, sinus tympani and recess of the facial n. The variatio...

The internal structure of a sunflower leaf could be reconstructed by applying RET reverse engineering techniques on measurements from terahertz time-domain probing (Time Domain Spectroscopy TDS). This new and non-destructive method allows us to follow the evolution this in time during process dehydration. paper is synthesis our previous work.

introduction frontal sinus mucoceles are the commonest among all paranasal mucoceles. with introduction of functional endoscopic sinus surgery, surgeons prefer endoscopic management of sinus mucoceles, but lesions that appear in the lateral part of the frontal sinus can be difficult to access and often need external approaches. case presentation we described a lateral frontal sinus mucocele wit...

As part of the multidisciplinary National Fire and Fire Surrogate study, we used drift fences with pitfall traps from May to September 2003 and 2004 to determine how three fuel reduction techniques affected shrews in the Southern Appalachian Mountains of North Carolina. Grounddwelling macroarthropods also were collected from a subset of pitfall traps to assess relative prey availability among t...

We investigated for the first time the occurrence of dimethylsulfoniopropionate (DMSP) in the leaves of Posidonia oceanica and we report its variability during 4 sampling periods covering the seasonal cycle (February, June, August and November) and along a gradient from 10 m to 30 m depth. The P. oceanica leaf DMSP content expressed per mass of dry weight (dw) ranged from 0.1 to 33.9 mol gdw−1 ...

Definition 3 A decision tree is a binary tree T. Each internal node of T is labeled with a variable xi and each leaf is labeled with a value −1 or 1. Given an input x ∈ {−1, 1}n, the tree is evaluated as follows. Start at the root; if this is a leaf then stop. Otherwise, query the value of the variable xi. If xi = −1 then recursively evaluate the left subtree, if xi = 1 then recursively evaluat...

OBJECTIVES This study aimed to investigate the anatomy of the intraorbital structures regarding to endoscopic sinus surgery and external frontal sinus surgery analyzing computer tomography (CT) scans. METHODS The CT scans of 100 patients were retrospectively evaluated. The anatomic relationships between the intraorbital structures and paranasal structures were measured using multiplanar recon...
