CECD decrease rates differ among patients, with some exhibiting rapid CECD decrease after corneal transplantation. Recently, we noticed a rapid postoperative CECD decrease in patient's eyes with severe preexisting iris atrophy after corneal transplantation, whereas patients with a healthy iris showed minimal decrease in CECD ().This suggests that the fate of CECD is, to an …

Nanofibers (NF) were isolated from bleached bagasse and rice straw pulps. The pulps were refined using high-shear ultrafine grinder and then homogenized using high-pressure homogenizer. The efficiency of the used isolation processes was studied by optical microscopy (OM), transmission electron microscopy (TEM), atomic force microscopy (AFM), and testing …

Development of high performance diamond impregnated wire is the key of application for fixed-abrasive wire sawing technology. In this paper, some experimental studies were done for development of electroplated diamond wire saw by employing the bright nickel bath. The wire saw electroplating process was developed, the effects of cathode current density and time at tack …

Introduction. The function of nitric oxide (NO) as a signaling molecule in animals has been intensively studied (Schmidt and Walter 1994).Increasing lines of evidence have also revealed its roles in plants (Delledonne et al. 1998).NO is involved in seed germination, de-etiolation, hypocotyl elongation, and stomatal closure (Beligni and Lamattina 2000; Guo et al. …

The CNC grinding process is shown in Fig. 6.The form-trued diamond grinding wheel shown in Fig. 2 was employed to perform a CNC grinding in the same grinder. Initially, the grinding wheel diameter and width were 200 mm and 13 mm, respectively.In grinding, a ceramic-bonded SiC block of 110×30×50 mm was chosen as the workpiece.The grinding parameters …

1 Introduction. For large earthquakes, per event displacement and dated recurrence from paleoseismic studies show that recurrence is quasiperiodic [Schwartz and Coppersmith, 1984].Similarly, stress drops and recurrence times from some instrumented intermediate and small earthquakes are highly regular [Ellsworth, 1995; Nadeau and Johnson, 1998].The spatial …

ESSG-based grinding method. A curve in the plane XOY, a quadratic curve for instance, rotates around the axis Y to generate a revolving aspheric or spherical surface in the workpiece coordinate system O-XYZ, as displayed in Fig. 1.The curve is called the generating line or generatrix of the surface, and axis Y is the rotation axis of the surface.

An electrolytic in-process dressing method, an electrolytic in-process dressing grinding apparatus, and an electrolytic in-process dressing grindstone, for grinding workpiece as the grindstone is being subjected to electrolytic in-process dressing, are provided, in which the grindstone is made of abrasive grains and a binding material which is capable of forming a uniform and fine …

Mandibular reconstruction using a titanium mesh tray and autologous bone is a common procedure in oral and maxillofacial surgery. However, there can be material problems—such as broken titanium mesh trays—which may undermine long-term functionality. This study was designed to investigate the optimal conditions for a titanium mesh tray with an ideal …
