Grunge Rubber Stamp Effect Step 1: Open up a stock image in Photoshop of any size and/or format. The best results for this tutorial usually involve large photographic images with effective color separation. Since the overall grunge effect will come out of this source image‚ it is best to select a photo with lots of vertical lines and straight edges going off at different angles. Rounded objects (especially ’natural’ objects) do not work very well. From personal experience I can say that construction-yard

If you were to go to the library and look in the science fiction section you would find an amazing novel called The Scorch Trials. This is a sequel to The Maze Runner also by James Dashner. In my opinion the major universal theme in this book is survival because the Gladers are tested to see if they can survive the harsh conditions of the Scorch. The novel is trying to inform people that in life you have to work hard for your goals‚ in this case the cure to a disease called the Flare. (“Thomas went

Date Learning Goals To visualize the interplay between the voltage‚ resistance‚ current and temperature in a conductor Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? The flow of current (+) is opposite to the flow of the electrons. ; note if toward or away from + terminal of the battery. The electrons move due to voltage of the battery‚so the battery causes an electric field which make the electrons

HVDC LIGHT TECHNOLOGY ABSTRACT [pic] Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC
