volume estimation of most agricultural products using mathematical methods is not accurate because of their irregular shape. an alternative method is image processing, which can be used in continuous sorting machines. the objective of this study is to find a practical method for volume estimation of potatoes using image processing. fifty potatoes (marfona variety) were selected as experimental ...

The de of Microstructure and magnetic properties of ferromagnetic Co9Pt nanowire arrays electrodeposited into self-assem anodic alumina templates have been investigated. X-ray diffraction shows that as-prepared Co–Pt nanowires a FCC polycrystalline structure. The nanowires with diameter do80nm are mainly of (1 1 1) preferred orientation th...

BACKGROUND AND PURPOSE Skull plain films of coiled aneurysms have been used in a limited role, including morphologic comparison of the coil mass. We aimed to evaluate the efficacy of skull plain films in patients treated with detachable coils by using quantitative assessment. MATERIALS AND METHODS In this retrospective study, 78 pairs of the initial and follow-up skull anteroposterior and lat...

OBJECTIVE To compare the intra- and interobserver agreement of three different methods of measuring lung area in fetuses with congenital diaphragmatic hernia (CDH). METHODS In 71 fetuses with isolated CDH at 21-33 weeks' gestation, the area of the contralateral lung was assessed by firstly, manual tracing of lung borders, secondly, multiplication of the longest diameter of the lung by its wid...

Cobalt nanowires with controlled diameters have been synthesized using electrochemical deposition in etched ion-track polycarbonate membranes. Structural characterization of these nanowires with diameter 70, 90, 120 nm and length 30 μm was performed by scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray diffraction techniques. The as-prepared wires show uni...

OBJECTIVE To establish reference intervals with gestation for the right and left lung areas and lung area to head circumference ratio (LHR). METHODS This was a cross-sectional study of 650 normal singleton pregnancies at 12-32 weeks of gestation. We measured the left and right lung areas on the cross-sectional plane of the thorax, used for examination of the four-chamber view of the heart, by...

We develop an analytical and quantitative theory of the tube model concept for entangled networks of semiflexible polymers. The absolute value of the tube diameter L perpendicular is derived as a function of the polymers' persistence length lp and mesh size xi of the network. To leading order, we find L perpendicular = 0.31xi 6/5 lp (-1/5) , which is consistent with known asymptotic scaling law...

The lattice dynamics in an array of 56 nm diameter Bi2Te3 nanowires embedded in a self-ordered amorphous alumina membrane were investigated microscopically using (125)Te nuclear inelastic scattering. The element specific density of phonon states is measured on nanowires in two perpendicular orientations and the speed of sound is extracted. Combined high energy synchrotron radiation diffraction ...

Methods Baseline data of 2,240 solid intermediate-sized nodules (volume 50-500mm) in 1,498 Dutch-Belgian NELSON trial participants were used. Extrapolated volume based on semi-automatic (SA) maximum diameter and mean of maximum transversal and perpendicular diameter were compared to SA volume measurements by Bland-Altman plots. Analyses were repeated by margin (smooth, lobulated, spiculated, an...
