Corrosion under insulation has become more critical in the industry for a number of reasons. For one, the industry as a whole has become more complex. Chemical, petroleum and food processing facilities, to name a few, require more sophisticated equipment, instruments and piping arrangements (see figure 4). Piping and equipment are more difficult to insulate, requiring highly skilled professionals. Corporations are reducing their staff and their budgets. Cost cutting is putting inspections and maintenance in jeopardy. These events can lead to a premature wet insulation system and eventually external corrosion to the pipe or equipment. Detecting corrosion under insulation (CUI) prior to serious damage or failure to the process system is imperative. With the current strict environmental laws, a process spill or failure can lead to legal ramifications. A close-up of the surface of a steel pipeline showing indications of stress corrosion cracking (two clusters of small black lines) revealed by magnetic particle inspection. Stress Corrosion Cracking (SCC) Stress corrosion cracking requires three components for it to attack As a result stainless steels do not normally suffer from this form of corrosion, but contact with galvanized steel can cause bimetallic corrosion to the zinc coating. Each year millions of dollars is spent in correcting the failure of pipe and equipment as the result of external CUI (see figure 15). This situation shouldn’t be surprising, since 95 percent of the failures go undetected until the product begins to seep through the insulation system into the ground or floor. Reviewing Corrosion’s Principles Before we discuss the inspection process of corrosion, it’s necessary to review corrosion’s basic principles. There’s no formula that will tell us actually the corrosion rate under insulation, but we do know that wet insulation systems accelerate the process. Uninsulated carbon steel and austenitic stainless steel can be exposed for years to all kinds of weather with only a noticeable film of surface corrosion on the substrate. Field testing to measure corrosion rate of various metals has been performed around the world under all types of environmental conditions. This information will tell us what materials corrode least under certain conditions, but they don’t tell us what happens under insulation in the same environment. Insulation systems provide the perfect environment for corrosion promotion. The physical characteristics of insulation materials can vary widely. Some insulation materials contain a leachable inhibitor to neutralize the Ph in the water. Some insulation types may not be hygroscopic. All of these features should be considered when selecting an insulation material for a specific project. However, this may only delay the inevitable corrosive process if no periodic inspection and corrective action is taken. After a number of years investigating corrosion failures under insulation, it’s apparent that no insulation or insulation system is exempt from external corrosion to the substrate. Fireproofing’s Contributions Fireproofing materials must be included as a contributor to a wet environment that promotes corrosion. Fireproofing materials also function in part as insulation between the critical structural steel and a potential fire. Not only is fireproofing applied to structural steel on buildings, but also on support legs and skirts of vessels and tanks. The same consideration must be made for the wet carbon steel surface under the fireproofing material and corrosion prevention. Moisture can enter a fire proofing system just as it does with insulation systems. Several years ago, we removed fireproofing from structural steel columns on a building located near an ocean. We found that the steel columns facing the ocean had actually corroded so badly that removing pieces of rusted scale left unsafe supports. It only took a few years for the salt (sodium chloride) in the atmosphere to cause this catastrophic condition (see figure 16). It must be assumed that every insulation and fireproofing system is subject to failure and thereby can promote corrosion. There are certain conditions that must be present. The insulation system must be exposed to moisture. The moisture may be created on a cold operating system by condensed vapor or it may simply be exposed to the weather.

I didn't change the cards, I changed the MEANING of the cards to what I wanted them to be. Here's a link to what I did: As you can see, I rigged who had the Tome to characters that were involved from a previous campaign so they could smoothly connect. After that, I removed the choices I didn't like and replaced them with choices I preferred, including interesting characters more then once to stack the deck in their favor. Then I wrote new descriptions that connected them to the cards. It struck the perfect balance that I wanted between randomness and direction, and removed the stupid joke options. Here's another option: Have the players draw the Tarokka cards themselves in session 0. Tell them that their choices will influence the game, but don't tell them what they mean yet. Then, once they get to the card reading in game, you know what the results are and can roleplay it far more dramatically. Of course, in between that time you can change the meanings of the cards however you want, and can flash the pages of the CoS book with all the readings if anyone tries to call you on stacking the deck. Has a lot of good discussion on that topic. This info I thought was very useful and is close to the stacking I've used. My solution for my group is that I am going to tell the players: this reading is EXTREMELY random and it can increase or decrease the difficulty of the campaign substantially. I (Madame Eva) will present them with the deck and offer them a choice: if they wish, they can choose to take what the fates have offered to them (in other words, what I pre-picked out as being fair choices and have stacked on the top of the deck); or, if they want luck to be the only master of their fates, they can shuffle the deck. For the pre-stacking, my choices for a fair but even campaign are: Tome: Master of Glyphs - Castle Chapel Holy Symbol: 8 of Coins - Vistani treasure wagon in Vallaki Sunsword: 2 of Glyphs - in the garden at the Abbey Ally: Mists - Ezmerelda Final fight: Broken One - Sergei's Tomb Here is my reasoning: The tome being in the castle makes sense (why would he have lost it somewhere else?). I am running the trial version of Adobe Acrobat. Adobe Acrobat Pro XI - Adding Javascript. Browse other questions tagged javascript pdf adobe acrobat. Jan 14, 2013 I have a form I am creating in Adobe Acrobat X. Content tagged with acrobat_x_javascript. What about a pop-up trigger by a checkbox? Here's a live demo using your ID names: I'll be honest with you, I didn't know you could embed HTML into a PDF like this! I actually meant the form code, that's my fault. I'm on a Mac and don't have Acrobat Reader, so I can see the form but not the code. The code you copy+pasted looks like it should work (other than the fact that there's a missing; after Totalclaimed2), but without knowing how 'event' is set, how FSA1 is set, etc I can't really help out. Know that if you want get the checked state of a checkbox with, say, ID 'Test' this won't work: if(Test.checked == 1) You first need to do this: Test = document.getElementByID('Test'); if(Test.checked == 1) That would work. I see your code. I had to change FSA to caps, so it recognized my fields. And the last line, I changed fsatotal.value to event.value. Var claim1 = parseInt(this.getField('TotalClaimed1').value), claim2 = parseInt(this.getField('TotalClaimed1').value), fsabox = parseInt(this.getField('FSA_Total').value); if( this.getField('FSA1').value == 'Yes') fsabox += claim1; if( this.getField('FSA2').value == 'Yes') fsabox += claim2; event.value = fsabox; Something is causing it to add every time the box is checked. Like the checking off of the box is what causes the addition. Its almost reading the code as 'When the box is checked, add the value to the total', so each time the box gets checked, it adds to the total again. And it should be 'IF the box is checked, add the value to the total' so if there is a value in the field, and the box is checked, that value is passed on to the total; and if the box is not checked, the value is ignored. Does this make sense? • A button can activate a single action or a series of actions. • A button can change appearance in response to mouse actions. • A button can be easily copied across many pages. • Mouse actions can activate different button actions. For example, Mouse Down (a click), Mouse Up (releasing after a click), Mouse Enter (moving the pointer over the button), and Mouse Exit (moving the pointer away from the button) can all start a different action for the same button. Buttons are an easy, intuitive way to let users initiate an action in PDF documents. Buttons can have a combination of labels and icons to lead users through a series of actions or events by changing as the mouse is moved. For example, you can create buttons with “Play,” “Pause,” and “Stop” labels and appropriate icons. Mame2003 / mame4all / FBA - unique roms.

Systems Community Reference Site Title Search Title: System: Region: MESS Emulator Tutorial by Tim 'Tooth Protector' Warner (timandsusan2002 at earthlink dot net) Table of Contents • • • • Introduction This tutorial will get you up and running in no time flat, playing games from a variety of different gaming platforms on your Microsoft Windows-based computer by using the outstanding (MESS) emulator. In this tutorial, we are going to focus on learning to play GCE Vectrex games by using MESS. However, the procedures outlined in this tutorial apply to any of the game platforms that are supported by MESS. Part One: Obtaining the Necessary Files To play GTE Vectrex games on your PC by using MESS, you'll need the following files: • MESS: As of this writing, the most recent version of MESS is 0.81. • Vectrex BIOS ROM: This file is required to play Vectrex games with the MESS emulator. • Vectrex Game ROMs: Vectrex game ROMs have the extension.GAM or.BIN. • Vectrex Screen Overlays: Vectrex screen overlays have the extensions.PNG and.ART. Visit the following Web site to download the latest version of MESS: Visit the following Web site to obtain Vectrex (and other) MESS BIOS ROMs: Note that you must have the appropriate BIOS ROM image for any game system that you want to access with MESS. Visit the following Web site to download Vectrex screen overlays: Visit the following Web site to download Vectrex game ROMs: Of course, judicious use of Google or one of the myriad peer-to-peer file-sharing applications should get you where you need to be as regards obtaining BIOS ROMs and game ROMs. Your first step is to use or some other ZIP file-management utility to unpack all of your files. Begin by creating a folder named MESS on your hard drive and unpacking the MESS emulator files into it. After the file extraction your MESS folder should look something like the following: Next, you'll want to place your ZIPPED Vectrex BIOS ROM in the MESS BIOS folder. Note that the actual BIOS ROM (which in the case of Vectrex is actually called SYSTEM.IMG) must remain in your VECTREX.ZIP archive file. Place your overlay files into the MESS ARTWORK folder. The VECTREX.ZIP overlay archive file that you downloaded earlier should remain zipped and placed, whole and entire, into the appropriate folder. Finally, place your Vectrex game ROMs into the MESS SOFTWARE folder. Part Two: Configuring MESS To begin, open your MESS folder and double-click MESSGUI.EXE to start up MESS. If you are wondering: Where are my systems? Where are my game ROMs? Then don't worry about it too much. We have to instruct MESS as to where everything is. That's what we will do now. First, let's point MESS to the location of our ROM BIOS files. From MESS, click Options => Directories. In the Directories dialog box, select BIOSses from the Show directories for: drop-down list box. Although there may already be an entry in the Directories list named BIOS, I tend to favor manually selecting the appropriate folder anyway. Therefore, select whatever entry appears beneath Directories and then click Browse. In the Browse for Folder dialog box, browse to the location of your MESS BIOS folder and click OK. You should now have a valid path configured for the BIOSes section of the Directories dialog box. Click OK in the Directories dialog box to return to MESS. In the left-most pane, click Available to display your list of available emulators. You should see an entry called Vectrex. If not, then click All Systems in the left-most pane and select Vectrex in the System pane.
