Use of Personal Protective Equipment 1. Purpose It is a requirement of the School of Chemistry and the University that appropriate personal protective equipment (PPE) be employed to minimise risks which may be present within a laboratory or workplace. This guideline discusses the various basic types of which are available to laboratory workers‚ briefly outlining their use‚ application and maintenance. 2. Scope This procedure applies to all personnel working in the School of Chemistry laboratories

positive charge to the sphere. 2. Laser Printer The core component of this system is the photoreceptor‚ typically a revolving drum or cylinder. The drum is positively charged by the charge corona wire‚ a wire with an electrical current running through it. As the drum revolves‚ the printer shines a tiny laser beam across the surface to discharge certain points. In this way‚ the laser "draws" the letters and images to be printed as a pattern of electrical charges

Glaucoma Glaucoma is a group of eye disorders that cause blindness by hurting the optic nerve‚ which is the large nerve that is responsible for vision. In glaucoma‚ the optic nerve damage is related to a change in the fluid pressure that circulates around the eyeball. In many cases‚ Glaucoma occurs when the eye’s fluid pressure is high‚ but it can also occur when the pressure is measured as normal. Fluid circulating inside the front portion of the eye is produced by a structure called the ciliary

refracted to a lesser angle‚ or a greater one. PROCEDURE: The materials that were needed for this experiment were: a table‚ a pencil‚ paper for notes‚ a laser‚ a platform‚ and a lens. The setup of the materials was as shown: Initially‚ before we began our experiment‚ we used the adjustment screws on the back of the laser to make sure that the laser-line went straight down the "normal" line on the platform. PART ONE: We aligned the flat

Pandora 16.1 This artifact was given the name Pandora because of the consequence of its mission. If any alien intelligent life acquired this artifact‚ they will acknowledge some important information about Earth including human race and our location in the galaxy. Then what is next? War or peaceful visit? Or it may never be discovered. I think the name is appropriate. The Number 16.1 represents its first model was designed in year 2016. The first prototype is made of aluminum alloy. Although titanium

If you ever wondered what is the most overlooked aspect of design craft‚ look no further – it’s user interfaces. Good or bad‚ user interfaces are everywhere: on websites‚ on mobile phones‚ televisions sets‚ wrist watches‚ airplanes and washing machines.Some user interfaces take two people to operate. Not my cup of tea.Whenever there is a user‚ there is user interface. Likewise‚ whenever there is a frustrated user‚ there’s usually a case of bad user interface.As graphic and web designers‚ our job
