Universal Precautions Universal precautions refers to the practice‚ in medicine‚ of avoiding contact with patients’ bodily fluids‚ by means of the wearing of nonporous articles such as medical gloves‚ goggles‚ and face shields. The practice was introduced in 1985–88.[1][2] In 1987‚ the practice of universal precautions was adjusted by a set of rules known as body substance isolation. In 1996‚ both practices were replaced by the latest approach known as standard precautions (health care). Nowadays

and successfully conducted. INTRODUCTION In fluid dynamics‚ Bernoulli’s principle is best explained in the application that involves in viscid flow‚ whereby the speed of the moving fluid is increased simultaneously whether with the depleting pressure or the potential energy relevant to the fluid itself. In various types of fluid flow‚ Bernoulli’s principle usually relates to Bernoulli’s equation. Technically‚ different types of fluid flow involve different forms of Bernoulli’s equation.

1.0 Introduction Water turbines are widely used throughout the world to generate power. By allowing fluid under pressure to strike the vanes of a turbine wheel‚ mechanical work can be produced. Rotational motion is then produced by the force generated as the jet strikes the vanes. One way of producing mechanical work from fluid under pressure is to use the pressure to accelerate the fluid to a high velocity in a jet. The jet is directed on to the vanes of a turbine wheel‚ which is rotated by

| What is Hydrocephalus and Why Does it Occur in Children? | | Dawn Sammler DeVry University | Abstract When having a child the main worry of a parent is that the child is healthy and has all 10 fingers and toes. But what happens when this is not the case? Hydrocephalus occurs in about 1 out of 500 children born. Parents are often unfamiliar with this disease and have trouble understanding what is going to happen with their child. Their dream of a healthy 10 fingers and toed child

Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping system.[1][2] Centrifugal pumps are used for large discharge through smaller
