Purpose: The aim of our study was to assess the variations in fusion and stereopsis before and after refractive surgery. Methods: We conducted a retrospective study. 140 patients (78 M, 62 F) were selected, aged 20 - 59 years (mean age 36 ± 10 DS). All patients received a comprehensive ophtalmological and orthoptic examination. Surgery was performed using a MEL-80 excimer laser (Carl Zeiss Meditec, jena, Germany). Results: Fusional convergence amplitudes after refractive eye surgery range from at near 18 - 20 PD in 42 (30%) patients;25 - 30 PD in 56 (40%) patients;35 - 40 PD in 42 (30%) patients, at far 20 - 25 PD in 84 (60%) patients;30 - 40 PD in 56 (40%) patients, fusional divergence at near after refractive eye surgery range from at near 6 - 8 PD in 108 (75.7%) patients;10 - 12 PD in 52 (37.1%), at far 6 - 8 PD in 126 (90%) patients;10 - 12 PD in 14 (10%) patients. None of the patients developed any ocular deviations. NCP, on average, decreases from 9.4 ± 1.5 cm to 9.1 ± 0.9 cm after. None of these patients with a normal NCP before surgery developed an abnormal NCP after refractive surgery. Eighteen patients (12.8%) had a stereopsis higher than 60 s of arch before surgical intervention. Of these, in 2 cases (2.8%) stereopsis increased from 200 to 40 s of arch after surgery. In the rest of patients stereopsis remained unchanged. Conclusion: The increase in fusion at near appears to be considerably interesting, whereas there is no worsening of stereopsis. A careful pre-surgery orthoptic evaluation is extremely revelant for a safe refractive surgery, this reducing the risk of complications associated with fusion and stereopsis.

Integrated Mineralogical Characterisation of Banded Iron Ores of Orissa and Its Implications on Beneficiation

Journal of Minerals and Materials Characterization and Engineering 2012年第12期11卷 1133-1142页

Iron is a primary raw material for steel industry. Increase in demand for steel puts pressure on iron resources of India in respect of its grade and reserve. With increase in demand for good grade of ore vis-a-vis its limited reserve, the utilization of low to medium grade iron ores is the order of the day with adoption of advanced beneficiation techniques. In order to find out the effective way of utilization, an in depth mineralogical study is essential as it throws light on the mineralogical peculiarities associated with the ores which affect the resultant beneficiation technique as well as the final product. In order to have a detail insight into the different mineralogical attributes, various characterisation studies megascopic, microscopic (both optical & electron), XRD, mossbauer and VSM are undertaken on the iron ores from different iron ore formations of Orissa. Importance of integrated mineralogical characterisation in beneficiation of iron ores is discussed.

jena及其同事一开始便坚信，防御性医疗比比皆是。但是，很明显的事实是，他们所援引的医生调查并未能坐实这一论断。防御性医疗或许只是医生践行“资源密集型医学”的一个原因而已。例如，那些肯定宽泛使用剖宫产手术可以减少临床围产儿灾难性事件的产科医生，可能自认为这是在采取防范手段，然而，对医疗事故诉讼的同等恐惧也许才是此举背后的真实动因。现实政策看重的是医生能否在低危诉讼情况下节约更多的有限医疗资源，至少在一种临床情境下可以选择“不”就是很好的例证。
