FLOATING SIPHON WITH A CONSTANT HEAD

A floating prosthesis for radial-head fractures.

We report our experience over seven years with a floating radial-head prosthesis for acute fractures of the radial head and the complications which may result from such injury. The prosthesis has an integrated articulation which allows change of position during movement of the elbow. We present the results in 12 patients with a minimum follow-up of two years. Five prostheses had been implanted ...

Constant time Floating Point Adder Circuits

Floating point unit is commonly used in computers. However, the arithmetic logic unit (ALU) for floating point operations such as addition or subtraction is complicated. Moreover, many floating point ALUs are designed to operate in many clock cycles. Thus, its speed are varied depend on the number of clock cycle. However, in many field, circuits with fix delay time are preferred. This work prop...

PENE1RATING HEAD INJURY WITH A KNIFE-A CASE REPORT

A case of a transcranial stab wound is presented in which the patient was stabbed in the left temporal bone with a knife which, after traversing the tentorium, passed through the occipital squama and its tip reached the upper cervical area. The subject underwent surgery and was discharged without neurological sequelae. The fundamental principles of management in this specific type of head ...

Approximate discharge for constant head test with recharging boundary.

The calculation of the discharge to a constant drawdown well or tunnel in the presence of an infinite linear constant head boundary in an ideal confined aquifer usually relies on the numerical inversion of a Laplace transform solution. Such a solution is used to interpret constant head tests in wells or to roughly estimate ground water inflow into tunnels. In this paper, a simple approximate so...
