In this paper, we describe a visual feedback system using a stereoscopic microscope. The system controls a micromanipulator so that a needle head may pierce a target as much length as desired. The tip position of the needle head and the target under the microscope are measured three dimensionally with two CCD cameras that are set to the eyepieces of the microscope. However, the visual feedback ...
OBJECTIVE The aim of this study was to identify the risk factors associated with the prognosis of a subchondral insufficiency fracture of the femoral head (SIF). METHODS Between June 2002 and July 2009, 25 patients diagnosed with SIF were included in this study. Sequential radiographs were evaluated for the progression of collapse. Clinical profiles, including age, body mass index, follow-up ...
Fourteen different morphological traits in 169 and 131 cattle of Oulmes-Zaer and Tidili, respectively were recorded and analyzed using a multivariate approach. The characters measured included heart girth, wither height, rump height, rump length, rump width, chest depth, body length, neck length, cannon circumference, ear length, ear width, head length, horn length and tail length. Breed signif...
BACKGROUND Case-control studies have found increased head growth during the first year of life in children with autism spectrum disorder. Length and weight have not been as extensively studied, and there are few studies of population-based samples. METHODS The study was conducted in a sample of 106,082 children from the population-based Norwegian Mother and Child Cohort. The children were bor...
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...
