Several methods have been described in the literature to both evaluate and document progression in keratoconus,but there is no consistent or clear definition of ectasia *** authors describe how modern corneal tomography,including both anterior and posterior elevation and pachymetric data can be used to screen for ectatic progression,and how software programs such as the Enhanced Reference Surface and the Belin-Ambrosio Enhanced Ectasia Display(BAD)can be employed to detect earlier ***,in order to describe specific quantitative values that can be used as progression determinants,the normal noise measurement of the three parameters(corneal thickness at the thinnest point,anterior and posterior radius of curvature(ARC,PRC)taken from the 3.0 mm optical zone centered on the thinnest point),was *** values were obtained by imaging five normal patients using three different technicians on three separate *** 95%and 80%one-sided confidence intervals for all three parameters were surprisingly small(7.88/4.03μm for corneal thickness,0.024/0.012 mm for ARC,and 0.083/0.042 mm for PRC),suggesting that they may perform well as progression determinants.

Boiling and fouling are taken as typical examples of new phase formation process to be analyzed and discussed in this paper. The process dynamics of nucleate boiling is analyzed and its mechanism is discussed from the view point of self-organization. Fouling, which is a more complicated phenomenon of new phase formation, involves series of underlying processes. The morphology and fractal analysis of fouling on low-energy surface and that with fouling inhibitors are studied and discussed. It is suggested that considering the process dynamics, fractal analysis and self-organization, a new avenue of research should be found.

Objective： To present our experience in treatment of difficult ununited long bone fractures with locking plate. Methods： Retrospective evaluation of locking plate fixation in 10 difficult nonunions of long bone fractures was done. Fixation was done with locking plate for femoral shaft fracture （3 patients）, supracondylar fracture of femur （gap nonunion）, fracture of clavicle, fracture of both forearm bones （radius and ulna） fracture of ulna, fracture of shaft of humerus, fracture of tibial diaphysis and supracondylar frac- ture of humerus （one patient each）. Five fractures had more than one previous failed internal fixation. One patient had infected nonunion which was managed by debridement with cast immobilization followed by fixation with locking plate at six weeks. Seven fractures were atrophic, two were oligotrophic, and one was hypertrophic. Fibular autograft was used in 2 cases and iliac crest cancellous bone graft used in all the patients. Results： Minimum follow-up was 6 months （range, 6 months to 2.5 years）. Average time for union was 3.4 months （range 2.5 to 6 months）. None of the patients had plate- related complications or postoperative wound infections. Conclusion： Along with achieving stability with locking compression plate, meticulous soft tissue dissection, acceptable reduction, good fixation technique and bone grafting can help achieve union in difficult nonunion cases. Though locking plate does not by itself ensure bony union, we have found it to be another useful addition to our armamentarium for treating difficult fracture nonunions.

Effect of pre-induced twinning on the microstructure evolution and mechanical properties of extruded Mg-9.26Gd-2.08Y-0.36Zr(Gw92K)alloy have been investigated during multi-direction forging with large strains at decreasing temperature from 400℃ to 300℃.The results showed that,whether there pre-induced twinning existing in the initial microstructure by pre-deformation or not,a mixed microstructure of residual coarse grains and notably refined grains formed under both conditions,combing with some residual coarse grains with less deformation inside grains and lots of dispersed nano-precipitates distributed along refined grain ***,a significant improvement with the tensile ductility was obtained by the pre-induced twinning in the former *** was suggested that,the pre-induced twinning largely contributed to the grain refinement and lead to an increase in the ratio of fine grain structure which would be responsible for the better ***,during subsequent forging deformation in the pre-deformed sample,the grain refinement mechanism by gradual grain orientation rotation around the surface section in residual coarse-grains was a little different from that by the macro-shear deformation in the as-extruded condition.

Phantom tumor of the lung is an infrequent presentation of volume overload in congestive heart failure. This finding is often mistaken for a lung mass that leads to extensive workup and unnecessary treatments. A 75-year-old male was evaluated for a right lower lobe rounded opacity. A transthoracic echocardiogram showed normal left ventricular function. Biopsy of the mass was unremarkable. Patient was managed with diuretics, and subsequent lung imaging revealed resolution of the opacity.
