Statement of Problem: Cephalometric findings are of high importance in making decision about orthodontic treatment plans and orthognathic surgeries. Natural head position (NHP) is considered as a useful and exact radiographic technique.Aim: The aim of the present study was to compare two techniques, namely Standard and NHP, in lateral cephalometry.Materials and Methods: In this cross- sectional...
Precise calculation of inlet pressure into sprinkler laterals is an important problem for proper distribution of uniformity. The adjusted average friction correction factor, FaAVG , provides the possibility of calculating the inlet pressure to mutli-outlet pressurized irrigation pipelines when the first outlet spacing from the pipe entrance is arbitrary. To investigate the effect of allowable h...
Conventional cephalometric analysis, based on intracranial reference line SN and Frankfurt plan, sometimes leads to incorrect diagnostic findings and unpleasant theraputic results, especially in orthosurgery patients, mainly due to the instability of the mentioned references. Natural head position (NHP) is the standardized orientation of the head that its record in lateral cephalometric radiogr...
Squalius janae, sp. nov., is described from the upper Dragonja River system in the Adriatic Sea basin in Slovenia. The new species is distinguished from other members of the S. cephalus species group by a combination of the following characters: a long head, head length, 29−32% SL, always markedly exceeding body depth; a pointed conical snout; a slightly subterminal mouth, with a clearly projec...
We assessed 70 hips at an average of 7.1 years after pinning for slipped upper femoral epiphysis to determine the frequency of remodelling, what factors influence it and its effect on the clinical outcome. Remodelling was defined by a new classification of the anterior femoral head-neck profile as seen on the lateral radiograph. Remodelling occurred in 50% of hips with a head-shaft angle of 30 ...
A new genus and species of Discocephalini, Acanthocephalonotum martinsnetoi gen. n. et sp. n. is described from Río Pichileufú, middle Eocene of Patagonia, Argentina at palaeolatitude ~ 46°S. The new species is the first fossil representative of the Discocephalinae. This taxon is extant in equatorial to subtropical America, and some species reach warm temperate latitudes (Buenos Aires province)...
A series of sled tests was performed using the Q3S anthropomorphic test device (ATD) and the ECE R44 sled buck to study CRS and pediatric occupant kinematics in far-side impacts. Using one model of convertible child restraint system (CRS), tests were performed using a 24 km/hr, 20 g pulse to compare ATD and CRS response to lateral loading in both forward-facing (FF) and rearward-facing (RF) con...
The present study was conducted to compare sperm motion characteristics of adult Malpura and Bharat Merino rams by the computer-aided sperm analysis (CASA) technique. Malpura is a hardy native sheep breed of the semi-arid tropical environment and Bharat Merino is a crossbred evolved in the same environment by crossing native sheep with exotic rams. Semen was collected from 8 donor rams of each ...
