article: When questions and conflicts arise in the relationships between sovereign nations, they are solved under the rules of public international law. This body of law consists of the treaties and legal decisions interpreting those treaties.  International law assumes that all the parties, as sovereign states, are equals. Conflicts arising under public international law can be settled either through diplomatic negotiations or in the International Court of Justice. This is the court of the United Nations. Fifteen judges, elected by the UN General Assembly, use international legal precedent to issue advisory opinions and solve legal disputes between governments.  The International Court of Justice has jurisdiction in two types of cases. The first is where the two countries agree to submit the conflict to the court. The second is when a treaty specifies the court as the legal authority over disputes. When citizens of different states have a legal dispute, there is often a question about what law applies. This choice of law question in civil issues, ranging from contracts to family law, is discussed in the Hague Conference on Private International Law. In general, courts will first defer to any contract or agreement clauses that identify what courts will have jurisdiction. In the absence of explicit choice of law language, the court will look to the overall circumstances of the contract, the behavior of the parties in creating the contract (called parol evidence) and if the parties can agree on jurisdiction. The customary international law is codified in the Vienna Convention on the Law of Treaties. Under this custom, states consistently adhere to certain practices out historical and legal obligation.

article: If you are experiencing the symptoms above you shouldn't waste time before booking an appointment with your eye doctor for a test. You can also, however, do some basic tests at home to try to measure your sight. Try by printing out the classic test page with letters of diminishing size from the internet.  After printing the test sheet, hang it at eye level in a well lit room. Stand ten-feet back and see how many letters you can read. Continue right to the bottom row, or as low as you can go, and write the number of the line where you could read most of the letters. Do this again, covering each eye at a time. The results vary by age, but older children and adults should be able to read the majority of the 20/20 line at the bottom. As well as printable test sheets, there are a number of tests that you can do directly on your computer. Again, these are not exactly perfect, but they can give you a basic indication of how your eyes are. You can find different tests for different eye problems, including colour blindness, and astigmatism.  They will involve you looking at different images and shapes on your computer screen, and following the instructions to test your eyes. Remember that these are vague guides, and should not be treated as a substitute for the real thing. Don't forget that if you are experiencing these symptoms you need to make an appointment with your eye specialist and have a full eye exam. Your optometrist or ophthalmologist will conduct a number of tests that will get to the bottom of your eye problems, and if you need glasses they will write you out a prescription. It might be intimidating or a little scary at first, but it's essential to caring for your eyes.  The eye doctor may use a number of instruments, aim bright lights into your eye, and have you try out a number of different lenses.  You will have to read out letters from a test sheet with while different lenses are held in front of your eyes. Ophthalmologists and optometrists are both qualified to conduct eye evaluations. After your eye exam you will be told if you need glasses or not. If so, you will be provided with a prescription. You can then take this to any optician's and choose which frames you want to get. Opticians are trained to help fit people for glasses. Once you have chosen your frames you will have to wait a week or two for the frames to be fitted before you can pick them up.

article:
Locate where the hoses connect on your vacuum and remove them by turning the ends counterclockwise. When both of the hose ends are loose, simply pull it off of your vacuum cleaner. Some hoses have small clips on them. If that’s the case for your vacuum, press down on the clip tab and pull it out from the port. If there’s a clog that you can see in either your hose or where the hose connects to the vacuum, try to reach in with a pair of needle nose pliers. Grab the blockage and pull it out from your vacuum so it doesn’t prevent any suction. Check your hose attachments and wand to see if there are any clogs in them that may prevent your vacuum from having full suction. Unravel a wire hanger so you have a long piece of metal that you can feed into the nozzles on your vacuum. Push one end of the wire hanger into the nozzles until you hit a clog. Push the wire up and down to try and break the blockage apart. When you’re finished, pull the hanger out of the vacuum cleaner.  You may also use a snake tool meant for cleaning vacuum cleaners. The tool may be found online. Be careful as you feed the hanger into your hose since the wire could puncture through it. Screw each end of the hose back onto the ports on your vacuum. As soon as they’re sealed, plug your vacuum in and test its suction. You should have full suction after removing all of the clogs.
