STUDY DESIGN Radiographic evaluation of cadaveric cervical spine specimens. OBJECTIVE Assess reliability and reproducibility of foraminal dimensions obtained from cervical radiographs of varying obliquity and determine optimal angles for visualizing foramina at each cervical spine level. SUMMARY OF BACKGROUND DATA Oblique radiographs may be considered to assess cervical foraminal dimensions...
A consecutive series of 85 patients with Duchenne's muscular dystrophy who underwent spinal fusion over a period of 16 years was followed up with regard to the progression of the scoliosis and pelvic obliquity. Of 74 patients with adequate radiographic follow-up, 55 were instrumented with the Luque single-unit rod system and 19 with the Isola pedicle screw system; seven were instrumented to L3/...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
In this large retrospective review of a clinical case, Derby et al (1) again show that the contralateral oblique (CLO) view is safe and accurate. Loss of resistance cannot be expected before the ventral interlaminar line (VILL) and the needle may be passed with impunity to just before this line. As the interlaminar line is accessed, the loss of resistance should occur immediately or shortly the...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
The synchrotron radio maps of supernova remnants (SNRs) in uniform interstellar medium and interstellar magnetic field (ISMF) are analysed, allowing different ‘sensitivity’ of injection efficiency to the shock obliquity. The very-high energy γ-ray maps due to inverse Compton process are also synthesized. The properties of images in these different wavelength bands are compared, with particulr e...
STUDY DESIGN Retrospective review of radiographic data. OBJECTIVES This study sought to define interobserver and intraobserver variability to further delineate reliable means by which radiographs of patients with neuromuscular scoliosis can be examined. SUMMARY OF BACKGROUND DATA Previous studies analyzed the use of Cobb angles in the measurement of idiopathic and congenital scoliosis, but ...
We present the measured projected obliquity – the sky-projected angle between the stellar spin axis and orbital angular momentum – of the inner planet of the HAT-P-17 multi-planet system. We measure the sky-projected obliquity of the star to be λ = 19 −16 degrees by modeling the RossiterMcLaughlin (RM) effect in Keck/HIRES radial velocities (RVs). The anomalous RV time series shows an asymmetry...
the changes in todays world organization, to the extent that instability can be characterized with the most stable organizations called this afternoon. if you ever change management component, an additional value to the organization was considered, today, these elements become the foundation the organization is survival. the definition of the entrepreneur to identify opportunities to exploit a...
