چکیده

Grain size and shape are important factors for yield quality. The difference in grain phenotypic characteristics the same maize hybrid is related to its position ear. This study aimed clarify distribution of morphological ear provide guidance research phenotype kernel effects. Three hybrids were used experiment, namely, Denghai 618 (DH618), KX3564, Xianyu 335 (XY335), number per row 40, 36, respectively. X-ray μCT was applied obtain five indicators, including length, width, thickness, volume, surface area. sphericity, length-width ratio, specific area, volume coefficient further calculated. results showed that there three types indicators trends: area parabolic; thickness sphericity inverted length-to-width ratio irregular. at different parts ear, namely relation between determined. average value middle grains taken select kernels representing stable variety. Within range 5% deviation from mean part accounted 26.39% total about 10 extending 14th base top. 10% deviation, 47.22%, 18 12th found greatly positions change rules as extend top Therefore, coefficients And representative sampling on determined based comprehensive analysis indexes variation grain.

Assessment of geometrical characteristics of dental endodontic micro-instruments utilizing X-ray micro computed tomography

OBJECTIVE The aim of this study was to quantify the surface area, volume and specific surface area of endodontic files employing quantitative X-ray micro computed tomography (mXCT). MATERIAL AND METHODS Three sets (six files each) of the Flex-Master Ni-Ti system (Nº 20, 25 and 30, taper .04) were utilized in this study. The files were scanned by mXCT. The surface area and volume of all files ...

Impact of Photon Spectra on the Sensitivity of Polymer Gel Dosimetry by X-Ray Computed Tomography

Introduction: The purpose of the current study was to investigate the effect of X-ray spectra on the sensitivity of a polymer gel dosimeter imaged with a conventional computed tomography (CT) scanner. Material and Methods: The whole process of CT imaging of an irradiated polymer gel was simulated by MCNPX Monte Carlo (MC) code. The imaging of polyacrylamide gel was accomplished by means of a co...

Morphological Characterisation of Unstained and Intact Tissue Micro-architecture by X-ray Computed Micro- and Nano-Tomography

Characterisation and quantification of tissue structures is limited by sectioning-induced artefacts and by the difficulties of visualising and segmenting 3D volumes. Here we demonstrate that, even in the absence of X-ray contrast agents, X-ray computed microtomography (microCT) and nanotomography (nanoCT) can circumvent these problems by rapidly resolving compositionally discrete 3D tissue regi...
