Article: When used correctly and consistently, condoms can help prevent pregnancy while still enjoying sex. There are a variety of colours, flavours, and textures available to use. You can buy them at a drugstore or get them for free at health clinics. Female condoms are also available to be worn. Just like condoms for penises, female condoms collect pre-ejaculate fluid and semen. However, they are less effective than male condoms. When used and applied directly, condoms are an effective method to prevent pregnancies. It's important you learn how to wear a condom, read the expiration date, and inspect that the condom is in working order. However, 18 out of 100 women have a chance of getting pregnant with condom use alone. Spermicide is a gel, foam, or film that is applied to a condom and works by blocking the entrance of the uterus with a sperm-killing chemical. They can be purchased at drugstores, pharmacies, and retailers or can be found already applied to certain brands and types of condoms. When used alone, vaginal spermicides are only 78% effective but if combined with a condom, the effectiveness increases to 95% or greater. For added protection, women may consider spermicides. Women should lie on their back briefly after engaging in intercourse to ensure the spermicide stays against the cervix. Spermicide can cause infections in both the vagina and penis and cause irritation to develop. Consult your health care provider if irritation or discomfort arises after using spermicide. The contraceptive sponge is a small, donut-shaped sponge that contains a spermicide and is placed within the vagina and along the cervix. You and your partner should not be able to feel the sponge if it is inserted correctly. The sponge is not as widely available as condoms and spermicides and they are often more expensive. Talk to your pharmacist if you cannot find one. To use a contraceptive sponge: First, wet the sponge with 2 tablespoons (30 mL) of water to activate the spermicide. Squeeze out the excess water. Insert the sponge into the vagina by sliding the sponge along the back wall until the reaches the cervix. The dimpled or concave side should face your cervix and the loop should face away for easy removal afterwards. Leave the sponge in for a total of 24 hours. You should leave it in for at least 6 hours after you have vaginal intercourse. Take out the sponge by washing your hands and taking a hold of the loop and then pulling it out of the vagina carefully. Make sure the sponge is in one piece after you have removed it. A diaphragm works similarly like a contraceptive sponge. Instead, the diaphragm is made of rubber with a flexible rim. Unlike the contraceptive sponge, diaphragms come in different sizes. Your doctor will measure your pelvis and order a diaphragm that you can insert before any sexual activity to prevent pregnancy. You can remove the diaphragm 6 hours after intercourse or after a 24 hour period. Note that diaphragms do not protect you from STIs.

Problem: Article: There are pros and cons to using Windows, Mac OS X, Linux, Chrome OS, etc. Visit each operating system's website to familiarize yourself with its features. Then, search the web for blogs that cater specifically to users of those operating systems. Reading user blogs is a great way to discover how people use their computers. Windows is pre-installed on most PCs and is used by businesses as both servers and workstations. Windows is also popular with home users and gamers who love tinkering with hardware. Mac OSX is known to be sleek and aesthetically pleasing. Made popular by artists, Mac OSX almost always runs on Apple hardware (although it can be installed on modern desktops) and has a familiar design that is gaining in popularity. Linux a free (usually) flavor of "Unix" used by more advanced computer users. It's highly customizable, secure, can be used on basically any type of hardware to perform any type of function. Chrome OS is a simple operating system found on Google Chromebooks. It's geared toward people who are more interested in using the web (and web applications) than anything else. To be a well-rounded computer genius, you should have experience using all operating systems and a wide variety of software. You can find Windows PCs at public libraries. Most college campuses have both PCs and Macs available for student use. Alternatively, you can ask a friend or a relative if you can try using their computer. Try doing the same sort of task (like browsing the web) on a Windows, Linux, or Mac computer and notice the differences. Both Macs and Windows have built-in System panels that provide details about the computer. Try to explore a new area of the Control Panel (Windows) or System Preferences (Mac) every day. Just poking around and clicking to view the different options will add necessary information to your budding genius brain. To open the Control Panel in Windows, press Win+S to launch the search, then type control panel. Click "Control Panel" in the search results, then browse through the various panels. To view System Preferences on your Mac: Click the Apple menu at the top-left corner of the screen, then click "System Preferences." If it's your first time, start with something easy, like a new web browser. If you're at a more advanced level, try installing Linux. Linux is a free operating system popular with the geeks (your team!) that can be installed on lots of different hardware configurations. Because Linux is so popular with people who love computers, there's an entire community of Linux users active on chats and forums. Learning Linux is bound to make you new friends, perhaps even a mentor.
Summary: Learn the differences between different operating systems. Use every opportunity to play with operating systems other than the one you use. Explore the operating system you use on your own computer. Install new software.

Use a spading fork to very carefully break up the compacted topsoil between the surface roots. Take care not to damage the roots themselves, and go no deeper than 1 inch (2.5 cm). Add garden soil to your newly broken-up topsoil layer, being very careful not to layer on more than 2 inches (5 cm) of new soil. If you add too much new soil, your tree's roots will suffocate, and the tree will eventually die. While you may need to replenish the new soil each year, do not add more than 2 inches (5 cm) of soil to the base of your tree per year. Adding some fertilizer will help keep your tree healthy and prevent the ground cover plants from using up too many valuable nutrients. Following the package directions, sprinkle a little 15-5-10 or 13-13-13 NPK fertilizer over the exposed root area. Pick a hearty plant that doesn't need a lot of sunlight or moisture. In general, the best times to plant ground cover plants are early spring and late fall. A few good options include: Wild violets Ajuga Periwinkle (vinca) Asiatic jasmine Monkey grass
