Q: Do this by clicking on its shortcut icon from your desktop or the app dock (if you're using a Mac). Click on "Safari" at the top-left corner of the menu bar and select "Preferences" from the drop-down list to open Safari's Preferences window. Click the gear icon on the right side of the Preference window to view the advanced settings of Safari. Now you can begin adding or editing any current proxies used within the browser. Select the kind of proxy you're about to use from the list of options available under the "Select a protocol to configure" list. Ask your firm's IT personnel if you're unsure what kind of protocol the proxy server you're about to connect to is. If you're just using a basic proxy server to connect to the internet, you can just select "Web Proxy (HTTP)" from the list. Do this on the respective text fields. Contact your firm's IT personnel if you don't know the IP address and port number of the proxy server you want to connect to. Click "OK" to save the changes made on Safari's proxy server setting. Enter the web address of the server you want to connect to on the address bar of Safari to test the connection.
A: Launch your Safari web browser. Go to Preferences. Go to Advanced Settings. Click the "Change Settings" button. Select a proxy. Enter the IP/HTTP address and port number of the proxy server you want to connect to. Save. Test the connection.

Article: Use a pipette to flood the bacteria sample with several drops of crystal violet dye, sometimes called gentian violet. Wait thirty to sixty seconds. Crystal violet (CV) dissociates in aqueous solutions into CV+ and chloride (Cl) ions. These ions penetrate through the cell wall and cell membrane of both gram-positive and gram-negative cells. The CV+ ion interacts with negatively charged components of bacterial cells to stain the cells purple. Many laboratories use "Hucker's" crystal violet, which adds ammonium oxalate to prevent precipitation. Tilt the slide and use a wash bottle to squirt a small stream of distilled or tap water over the top of the slide. The water should run down over the surface of the smear, but not be aimed directly at it. Do not rinse excessively, which might remove the stain from Gram positive bacteria. Use a pipette to cover the smear with iodine. Let it sit for at least 60 seconds, then rinse off with the same careful method. Iodine, in the form of negatively charged ions, interacts with CV+ to form large complexes of crystal violet and iodine (CVI complexes) within the inner and outer layers of the cell. This will trap the purple crystal violet colour in the cell, wherever it has stained. Iodine is corrosive. Avoid inhalation, ingestion, or skin contact. A 1:1 mix of acetone and ethanol is typically used for this critical step, which must be timed carefully. Hold the slide at an angle, then add the decoloriser until no more violet colour is visible in the draining runoff. This typically takes under 10 seconds, or even less time if the decoloriser contains higher concentrations of acetone. Stop immediately, or the decoloriser will remove the crystal violet stain from both gram-positive and negative cells, and the stain will have to be repeated. Immediately rinse off excess decoloriser, using the earlier technique. Pure (95%+) acetone can be used instead. The more acetone there is, the faster the decoloriser will work, requiring more precise timing. If you are having trouble timing this step, consider adding the decoloriser drop by drop. A counterstain, typically safranin or fuchsin, is used to add extra contrast between gram-negative and gram-positive bacteria, by staining decolorised (gram-negative) bacteria pink or red. Leave it on for at least 45 seconds, then rinse off. Fuchsin will stain many gram-negative bacteria more intensely, such as haemophilus spp and legionella spp. This may make it a better option for beginners. You may allow the slide to air dry, or blot it dry using bibulous paper sold for this purpose. The Gram stain is complete.
Question: What is a summary of what this article is about?
Flood the smear with crystal violet. Rinse off the crystal violet gently. Flood the smear with iodine, then rinse. Add a decoloriser, then rinse quickly. Flood the smear with counterstain, then rinse. Dry the slide.

Q: Place your aluminum piece on a sheet of aluminum foil with the shiny side facing away from the aluminum piece. Fold the foil over so it covers the aluminum piece but is not sealed. The aluminum foil creates distortions as well as a rainbow pattern on the aluminum due to the heat and chemical reaction. Keep the open ends of the aluminum foil facing upwards so that the water can run down into the package. Stack your pieces in the dish rack of the washer. Add powdered dishwashing detergent, like Cascade Complete or Finish Dishwasher Powder, to the dispenser. Then, add 1 teaspoon of trisodium phosphate (TSP) to the dispenser. TSP can be found at your local hardware or home improvement store. Age the aluminum by running the dishwasher on the pots and pans cycle. Turn on the drying cycle as well. After the cycle is complete, carefully remove the aluminum pieces from the dishwasher. Use caution, as they may be hot. Remove the foil around the aluminum. If you want to add more patina or increase the aged look of the aluminum, wrap the pieces in aluminum foil at a different orientation and run them through the dishwashing cycle again.
A:
Wrap your aluminum piece in aluminum foil. Load your aluminum pieces in the dishwasher. Fill the dispenser with powdered dishwashing detergent and TSP. Run the pots and pans cycle. Remove the pieces from the dishwasher. Repeat the process to add more patina.
