| 1 | EXPERIMENTAL AND FIELD STUDY ON MINING-PIT MIGRATION显示文摘Rivers are one of the most essential sources of sand and gravel supply for civil works. However, undesirable effects of irregular in-stream mining have been reported on natural sources, environment and infrastructures close to rivers. Therefore, it is necessary to find the effects of mining on rivers in more details. This research concentrates on mining-pit migration phenomenon and its effects on the channel bed. This paper reports an experimental study on the migration of rectangular mining pits and variation of longitudinal profile in the channel bed composed of rather uniform sediments. Different values of widths and lengths were used for pit while pit depths and flow variables were kept constant. The results show that the migration speed changes with the length/width ratio of the pit. The migration speed in convection period is higher than that in diffusion period. In addition, by increasing the length or width, filling rate of pit increases, where the effect of width is more important than the effect of the length. Also is reported in this paper a field study on the changes of three pits excavated at different locations of a river. Some similarities between the pit migration in the straight reach of the river and that of the experimental work is realized and presented. | S.Ali Akbar Salehi NEYSHABOURI Ali FARHADZADEH Ata AMINI | 2002 | International Journal of Sediment Research2002，17，4： | 9 |
| 2 | Evaluation of early results of quick-chop phacoemulsification in the patients with high myopic cataract显示文摘AIM:To assess the early surgical outcomes of quickchop phacoemulsification technique in patients with high myopia.METHODS:The data of patients with high myopia who underwent quick-chop phacoemulsification were reviewed retrospectively. There were 42 eyes of 31 patients. The axial length was more than 26 mm in all eyes. All eyes underwent quick-chop phacoemulsification surgery with the placement of an intraocular lens(IOL) in the capsular bag. Postoperative visits were performed at 1, 3d; 2wk,1mo. Early postoperative best corrected visual acuity(BCVA), preoperative and postoperative corneal endothelial cell density(ECD), central corneal thickness(CCT) and postoperative complications were assessed.Paired sample t-test or Wilcoxon tests were used to compare data between preoperative and postoperative data.· RESULTS:There was no statistically significant difference between preoperative and postoperative ECD and CCT. Retinal detachment was developed in one eye at postoperative first day. There was an iris prolapsus from side port insicion.· CONCLUSION:Quick-chop phacoemulsification technique is a safe surgical technique. However we can encounter some complications in high myopic eyes due to histopathological differences. Both side port and clear corneal tunnel insicion size is crucial for preventing postoperative complications. If any persistent leakage is noticed, suture should be placed. | Ali Akal Tugba Goncu Sevin Soker Cakmak Isa Yuvaci Mustafa Atas Süleyman Demircan Omer Faruk Yilmaz | 2014 | International Journal of Ophthalmology(English edition)2014，7，5： | 4 |
