Morphometric comparisons of two populations each of Races 1 and 2 of Meloidogyne arenaria from tobacco, peanut, and soybean in different localities in Florida showed no significant differences in any characters measured by light microscopy. Thirteen morphometric characters of females, 22 of males, and 21 of infective second-stage juveniles were measured for each population. The stylet length in...

Ontogenetic studies of vertebrate feeding performance can help address questions relevant to foraging ecology. Feeding morphology and performance can either limit access to food resources or open up new trophic niches in both aquatic and terrestrial systems. Loggerhead sea turtles are long-lived vertebrates with complex life histories that are marked by an ontogenetic shift from an oceanic habi...

A long-standing hypothesis for the adaptive radiation of macrostomatan snakes is that their enlarged gape--compared to both lizards and basal snakes--enables them to consume "large" prey. At first glance, this hypothesis seems plausible, or even likely, given the wealth of studies showing a tight match between maximum consumed prey mass and head size in snakes. However, this hypothesis has neve...

DR. MARQUARDT It does seem to occur throughout nature in many biologic systems, including flowers and the leaf divergence from a stem in plants, and particularly in humans. For example, the width of the nose to the width of the mouth is a ratio of 1:1.618 in a beautiful face. In an ideal dentition, the width of the maxillary central incisor is 1.618 times the width of the maxillary lateral inci...

The objectives of this study were to estimate the maxillary arch measurements, to assess the validity of Pont's & Korkhaus' Indices; to determine the relationship between maxillary arch form with head form; and to estimate the cephalic index (CI) of the study population. A cross-sectional study was conducted on 85 mature Malay students, 28 male students (32.98%), 57 females (67.02%) attending T...

This thesis gives an overview of the research of a system that generates a 3D model of a human head from 2D images. The location and size of the eyes, eyebrows, nose and mouth in 2D orthogonal images are detected using skin color detection, template matching, value detection and a anthropometric model. The results of these detections are combined for more robust results. Manual initialization i...

BACKGROUND The treatment of the condylar fractures is difficult. Factors that result in the fractures are complex. The objective of this morphometric study was to investigate the relationship between condylar fracture patterns and condylar morphological characteristics. METHODS We conducted a retrospective analysis of 107 patients admitted to the West China Hospital of Stomatology for bilater...

in order to study the gene actions and heritability of the physical and chemical characteristics associated with appearance and cooking quality of rice grain, generation mean analysis was performed using a cross between two iranian rice cultivars, deylamani and sepidroud, having different quality characters. seeds of the parental lines and f1, f2, bc1 and bc2 generations were grown in randomize...
