BACKGROUND Bone density at the interradicular area plays an important role during orthodontic treatment. In view of this fact, the study was designed to quantitatively evaluate the bone density at the interradicular areas of the alveolar and basal bones of maxilla and mandible by computed tomography. METHODS One hundred and nine computed tomographic images were randomly selected, and bone den...

In this paper strong limits on the accuracy of real-world physical computation are established. First it is proven that there cannot be a physical computer C to which one can pose any and all computational tasks concerning the physical universe. Next it is proven that no physical computer C can correctly carry out any computational task in the subset of such tasks that can be posed to C. This m...

Carcinoembryonic antigen and some liver function tests (alkaline phosphatase, gamma-glutamyltranspeptidase, lactic dehydrogenase and cholinesterase) were evaluated in patients with primary colorectal cancer in order to define their role in the pre-operative detection of liver metastases. The records of 278 consecutive patients admitted to the Istituto Nazionale Tumori of Milan between January 1...

Precise reconstruction of the morphological structure soybean canopy and acquisition plant traits have great theoretical significance practical value for variety selection, scientific cultivation, fine management. Since it is difficult to obtain all-around information on living plants with traditional single or binocular machine vision, this paper proposes a three-dimensional (3D) method recons...

a factorial pot experiment based on randomized complete blocks design with fourreplications was carried out in order to evaluate salt tolerance of four sugar beet cultivarsincluding madison (british origin) and three iranian cultivars (7233-p12, 7233-p21 and7233-p29) using carbon isotope discrimination (δ). plants were grown in sand culturemedium in greenhouse conditions. sugar beet cultivars w...
