Pelvic Injuries

The purpose of this report is the determination of the diagnostic reliability of routine radiologic and CT examinations for pelvic injuries in children. The comparative analysis of these examinations and postmortem morphologic studies of pelvic spesimens was performed in 10 children, aged 2-12 years. It was shown that the X-ray method allowed to diagnose only 47.37% and CT method - 76.32% of all real pelvic injuries (by morphological data) in those children. However, the detectability of damage of the structures that formed the anterior pelvic semi-ring was 50% by radiologic examination, and 60% by CT examination, while for the structures forming posterior pelvic semi-ring it was 44.44% and 94.44%, respectively.

The work evaluates the stress deformed state of the section of the interfield gas collecting main, running in permanently frozen grounds. The object of research is a section of a pipeline with an arched discharge formed as a result of loss of stability as a result of thermal erosion of permanently frozen grounds to disturbance of the vegetation cover. The determination of stresses was carried out by the X-ray method using portable equipment. The experimental data were analyzed with the calculated. The calculated data were obtained by measuring the spatial position of the gas pipeline section. The obtained values of the acting stresses and the estimates of the critical indicators of the gas pipeline monitoring section made it possible to reasonably estimate the stress state. The methodology for determining the acting stresses of pipelines using portable X-ray equipment can be successfully applied to estimate the stressed-deformed state of pipeline systems running in the zone of permafrost.

Good Agreement

A method is presented for the determination of carbon in solid hydrocarbons using the intensity ratio of incoherent to coherent scattering of x-rays. The method is very rapid with precision at the 95% confidence level of about ±0.3%. The minimum sample weight necessary is 0 2 g. Analysis of samples by the x-ray method shows good agreement with values obtained by microcombustion. Finally a general comparison between different methods for carbon determination in solid hydrocarbons is discussed.

The Difference

SummaryThree new analyses of kalsilite are given, with optical and X-ray data; two (K/(K + Na) = 0·95. 0·98) are from rocks where it is closely associated with nepheline. An analysis of one of the nephelines is also given (K/(K + Na) = 0·31). The cell dimensions vary appreciably with sodium content, and the composition of kalsilite may be determined from the equation:100 K/(K + Na) = 100−227·27(Δ 6·264),where Δ is the difference, in degrees, between the diffraction angles 2ϑ for 102 and 101, using Cu-Kα radiation.
