During the steel continuous casting, submerged entry nozzle (SEN) plays a crucial role in fluid characteristic of steel, which further affects slab quality. In this paper, model is developed to study influences inclination, area ratio, and side hole aspect ratio on steel. The results show that when angle increased from 10° 20°, impact points narrow surface were 0.402 m, 0.476 0.554 m away menis...

PURPOSE The purpose of this analysis was to determine whether dynamic measures of vision, such as dynamic acuity and motion threshold, are independently associated with self-reported difficulty in activities involving vision. METHODS Data were used from the third round of the Salisbury Eye Evaluation (n = 1198), a longitudinal, population-based study of older adults. Multiple measures of visu...

We assessed the appropriate geographic scale to apply an area deprivation index (ADI), which reflects a geographic area's level of socioeconomic deprivation and is associated with health outcomes, to identify and screen patients for social determinants of health. We estimated the relative strength of the association between the ADI at various geographic levels and a range of hospitalization rat...

The Q-depth relation in the earth's mantle has been estimated for long-period P waves from two deep-focus and three intermediate earthquakes. The amplitude spectrums of the first P waves from 114 seismograms at recording stations inthe distance range between 15 and 103 degrees, have been corrected for the crustal structure and the instrument and used to measure the effects of attenuation ver th...

BACKGROUND Modeling studies using hypothetical polygenic risk data can be an efficient tool for investigating the effectiveness of downstream applications such as targeting interventions to risk groups to justify whether empirical investigation is warranted. We investigated the assumptions underlying a method that simulates risk data for specific values of the area under the receiver operating ...

BACKGROUND In Switzerland, as in other developed countries, the prevalence of overweight and obesity has increased substantially since the early 1990s. Most of the analyses so far have been based on sporadic surveys or self-reported data and did not offer potential for small-area analyses. The goal of this study was to investigate spatial variation and determinants of obesity among young Swiss ...
