Problem: Article: A conduit channel might sound like something a professional electrician has to install, but it's actually just a cover made to disguise electrical cords. Conduit channels, also called raceways, can be installed along the floor or down a wall, then painted to blend in perfectly with your color scheme. If you have long wires connecting your speaker system, keep them off the floor by running them along your baseboards and over your door frames. You can attach them by using nail-in cable clips, which you can get at a hardware store. To completely camouflage wires, drill a hole in your wall or your floor near your speakers, then drill another one close to your power outlet. Feed the wires into the first hole, then fish the wires through the second hole. If you're buying new floorstanding speakers, you don't necessarily have to deal with wires at all. There are a number of wireless speakers available on the market, and the models range from basic speakers to high-end acoustics.
Summary: Hide cords in plain sight with a conduit channel. Hide long wires along your baseboards and around doors. Run the wires under your flooring or in your wall for an invisible look. Go wireless to avoid the issue altogether.

INPUT ARTICLE: Article: Bake them at 160 C for 25 minutes. The time may vary depending on the thickness of your slices. You may serve it with a healthy meal or to accompany your burger.

In one sentence, describe what the following article is about: If you suspect your rabbit has heat stroke, you need to immediately cool him down. Start by bringing him out of the heat into a cooler environment. For example, if your rabbit is in a room with full sun, move him into a shady air-conditioned room. While you may think you should rush to the vet right away, start cooling your rabbit down before you take him. Use a fan to blow cool air over his fur, paying attention to his ears. This will help lower your rabbit's body temperature. You can also dampen his fur with cool water before blowing air over it to cool your rabbit more effectively. Don't apply ice or ice-water because the extreme temperature change could send your rabbit into shock. Give your water plenty of fresh cool drinking water. Place the bottle water dropper beside him so he doesn't have to move far to drink. You may also set out a bowl of water so your rabbit can choose between it and the bottle water dropper. The main thing is to keep your rabbit hydrated. You can also put ice cubes in the water to keep the water chilly. At the first sign of heat stroke (as soon as you recognize symptoms), move the rabbit to a cooler area and contact the veterinarian. Since heat stroke can become lethal very quickly, your rabbit needs immediate veterinary care. In extreme cases, the vet may put your rabbit onto intravenous fluids which can cool his blood and support organ function.
Summary: Remove your rabbit from the heat. Cool your rabbit's fur. Offer water to drink. Know when to get medical attention.

Carbon dioxide, or CO2, can safely and effectively lower and stabilize your pool's pH. A variety of CO2 systems for pools are available, some of which can automatically analyze your pool's pH and adjust their output accordingly. These devices are available through specialty pool and spa supply stores. Some CO2 systems are fully automated, while others have to be controlled manually. Consult a specialist at a pool supply store to determine what type of CO2 system is best for your pool. These systems can be expensive, ranging in price from $300-$10,000 USD. However, a CO2 system may ultimately save you money, since it minimizes the need for frequent pH and chlorine adjustments. Unless you have a lot of experience installing pool equipment, it is probably best to have a pool technician install the CO2 system for you. Consider consulting a professional before you purchase a CO2 system, so that they can help you determine whether the system is a good fit for your pool. Since CO2 can raise your pool's total alkalinity, it is best not to use a CO2 system if your water already has a high total alkalinity (i.e., if water tests reveal it is over 125 ppm). CO2 is also less effective at lowering pH if your water is hard. Consult a pool technician to determine if your water conditions are right for a CO2 system.
