article: Inspect the floor carefully for deep cracks, gouges, and places that have sunken due to continual wear. Fill in these areas by slathering a small amount of patching compound directly over the problem area using a hand trowel. Smooth the compound with the flat side of the trowel and use the edge to work it further into deep openings. Allow the patching compound to cure completely before proceeding. This may take 1-4 hours, depending on the exact product you use. You can find pre-mixed patching compound at any hardware store or home improvement center. Unless your floor is severely damaged, you'll most likely only need a small bucket. with an electric buffer or sander to make sure it's level. Switch on your polisher and guide it over the surface of the concrete in tight, overlapping circles. Work your way gradually from one end of the room to the other, focusing on areas that are marred by obvious imperfections, such as divots and uneven textures, as well as the places you filled in with patching compound. Polishing may not be necessary if your concrete floor is relatively new. However, it's a good idea to go ahead with the process if the concrete shows any paint splotches, oil stains, or similar residue. If you're staining a concrete floor that was previously covered with tile, you'll need to use a floor grinder equipped with diamond bits to remove stubborn scraps of dried mortar from the floor. You may need to use an extension cord to polish large rooms like foyers or galleries. Go over the entire surface using a powerful Shop-Vac to suck up the dust generated by polishing. Try to get up as much lingering debris as possible. Don't forget to suction the corners and the area around the baseboards, as well. If you don't have a Shop-Vac on hand, sweep up as much dust as you can with a heavy push broom and dustpan, then go over the area again using a standard household vacuum with a floor attachment. Squeeze some grease-cutting liquid dish soap into a large bucket, then fill the bucket with warm water. Stir the soap and water together until they form a sudsy solution. Mop the floor from corner to corner, or scrub it using a stiff-bristled broom or thick handcloth. After cleaning the floor, go over it with a squeegee to remove as much standing water as possible. If your floor is especially grimy or oily, you may need to apply a small amount of trisodium phosphate (TSP) or a similar degreaser to lift away heavy residue. Concrete stains tend to stick better to floors that have been chemically etched prior to application. If you want to etch your floor, pick up a bottle of etching acid and follow the specific instructions laid out on the label. Most types of chemical etching agents need to be mixed with warm water and scrubbed onto the floor using a rigid brush. Not all concrete stains require the surface to be etchedin fact, some products advise against it. Be sure to read the recommended uses of the stain you're working with before you attempt to etch your floor. When applied correctly, the etching acid will create tiny imperfections in the smooth concrete, making it easier for substances like stains to permeate the surface. Stretch a roll of painter's tape along the perimeter of the room where the lower part of the wall meets the floor. This will prevent the stain from getting anywhere it's not supposed to be. You can also cover any parts of the floor you plan on leaving exposed. Take your time and work carefully to make sure everything is properly protected. Concrete stain can be extremely difficult to remove once it's been applied.

article: A bachelor's degree is required for all PhD program applications and a master's degree may be required for some PhD programs. GRE (Graduate Record Examination) scores are often required for admittance into PhD programs in the US, so it is a good idea to take the GRE before you can apply. It takes a couple of months to get your scores back, so make sure that you take the GRE well in advance of beginning the application process. Taking the GRE three to six months in advance is a good idea. You may even want to take it about year before you plan to apply, just in case you do not get a good score and you need to retake it. If you are from a country where English is not the official language, then you will have to take the TOEFL (Test of English as Foreign Language or IELTS (International English Language Testing System). These tests assess your English language skills and help schools determine whether or not you are equipped to attend graduate school at an English language university. Like the GRE, you should take one of these tests well in advance of starting the applications. Score requirements vary by university, so check with each university to learn the score requirements before you apply. For TOEFL, you need to have at least a 600 on the paper-based test OR above a 95 to 100 on the internet-based test. For IELTS, you need to have above a 7.0 to 7.5. Fees for international student PhD applications can be quite high, such as around $100 US dollars per application. Since you will likely need to apply to several schools in order to have a chance at a job, make sure that you can afford the fees before you start the process. For example, if you plan to apply to 20 different programs, then you will need to ensure that you have about $2,000 for the application fees. Keep in mind that the fees may vary drastically among schools. More prestigious schools may charge higher application fees than less prestigious schools. Each school will have its own application process and some schools also have special requirements. For the best chance of getting an acceptance letter, make sure that you carefully read the application instructions for each school that you plan to apply to. Identify any special requirements that you will have to fulfill before you apply. For example, some programs require applicants to answer a specific question or set of questions in the statement of purpose. Having a few glowing letters of recommendation from professors and/or higher education administrators will improve your chances of getting accepted to a PhD program as well. Ask professors who know you well and who can evaluate your ability to do doctoral work. For example, it would be better to ask a professor in your discipline than someone who taught an elective class that you enjoyed. Having one letter of recommendation from an administrator or employer can be helpful to show a different perspective of your academic goals. For example, you might ask your department's chairperson, one of the university's deans, or a current or former boss. As with the professors you ask, the administrator who recommends you should be someone who will give you a glowing recommendation. Transcripts are required for your application, so make sure that you know the procedure for requesting them from your university and put in your requests as soon as possible. Since your applications will be traveling via international mail, it is important to allow plenty of time for them to arrive. Keep in mind that most schools require official transcripts. Sending transcripts may or may not require you to pay fees, depending on your university's policies. Some types of programs require applicants to submit a writing sample as part of the application. This sample should be something that reflects your research interests and demonstrates your writing and research abilities. Choose something that you are proud of. If you have a piece that has been published, then this is an especially great choice for the writing sample, but unpublished pieces are fine as well.

article:
These two tabs, located next to the power plug, will probably need to be popped at the same time (they can be done one at a time but this is more difficult). This is when you will want to take advantage of the second small screwdriver. Using both of these or the case opening tool, pop the tabs and start to pry the shell open. At the other end of that side, you will see five more of these tabs. Pop them one at a time, keeping constant pressure as you open the shell, or use the case tool to open them all at once. Flip the 360 around to look at the front end, find the clip at the end near the DVD drive. This can be easily opened with your fingernail or a flathead screwdriver and a good deal of prying. There should be four tabs on this side, which you can take one at a time. With the shell removed, you should be able to see the inner casing now. Open this by unscrewing the cover panel. Flip the Xbox onto the opposite side and pull off the remaining shell to reveal the inner components.
