Pterygium is characterized by an elastic degeneration of the conjunctiva that extends across the limbos and invades the cornea. The recurrence rate is varied from 25-80% after primary closure to 6% with free conjunctival and Iimbal grafts. Several adjunctive therapies have been investigated for recurrent pte¬rygium. This article presents a 52-year-old athletic man who was seen for evaluation of...

Equilibrium-tension lysimeters were used to evaluate and compare dissolved reactive phosphorus (DRP) leaching from a prairie and fertilized no-tillage and chisel-plowed corn agroecosystems on Plano silt loam (fine-silty, mixed, superactive, mesic Typic Argiudolls) in south central Wisconsin during four monitoring periods, March through April 1996, 1997, and 1998, and from January 1999 through S...

This work performs the analysis and simulation investigations of penetration behaviors of chisel-shape projectile. In analysis, the projectile is assumed to be a rigid body and the target plate is elastic-plastic material. By introducing the velocity potential function, the velocity field in target is first obtained. Then, the momentum equation is solved for determining the pressure and stress ...

Graphical description techniques are especially useful in the early development phases like requirements engineering. There, often a trail-and-error approach is applied to develop a first system specification. However, even there a precise meaning of those description techniques is necessary, especially in trial-anderror phases based on a service-oriented description of the requirements to chec...

The turning process is one of the machining processes for producing machine components. Where lathe included in that uses a chisel. quality cut surface depends on cutting conditions, example low with large feed and depth will result rough so on. This study aims to determine what effect angle length use chisel, where chisel used an HSS In this using experimental research methods aim knowing time...

in order to determine the effect of different tillage methods on grain yield and yield components of two wheat cultivars an experiment was conducted in sanandaj in during 2005 and 2006-2007. experiment was carried out in a split plot design based on rcbd with four replications. the three methods of tillage, including moldboard plow, chisel plow and no tillage were arranged as main plots, and tw...

Abstract Aims Cracks and biopores in compacted soil such as plough pans could aid deep rooting, mitigating constraints to seasonal upland use of paddy fields for rice production. This research investigated how macropores through a simulated pan affects root growth contrasting shallow rooting genotypes. Methods Deep Black Gora IR64 varieties were grown packed cores unsaturated controlled greenho...

With the current ever-increasing demand for performance, hardware developers find themselves turning ever-more towards construction of application-specific accelerators to achieve higher performance and lower energy consumption. In order meet ever-shortening time constraints, both development verification tools need be improved. Chisel, as a language, tackles this problem by speeding up digital...
