Q: If the recruitment page on the department’s website offers an online application, complete it there. Otherwise, contact the department to find out how to apply, since the process varies. Some may ask you to complete an application before doing anything else. Others may have you fill one out and take the entrance exam on the same day. Either way, set aside plenty of time to fill out the application, since it is far longer than most.  Fill your application out honestly, since a very extensive background check will ensue. You may also have to submit to a polygraph test later on. To apply, you generally need to be at least 21 years old, a U.S. citizen, and a high school graduate. Study beforehand for the civil service exam. Expect sections that will test job-specific skills, such as your ability to read maps, write reports, and accurately recall in detail observations that you’ve made. Also concentrate on sections that test your verbal skills, since these are arguably one of the most important skills for a police officer to have, whether they’re interacting with citizens, communicating information in a crisis, or testifying in court. Expect your speed, endurance, and agility to be challenged. Tests vary from one department to another, but prepare to run either a short distance with maximum speed, a long distance at a consistent pace, or both. Perform simulations of real-life possibilities, such as climbing, moving a dummy/body, completing an obstacle course, or pushing a car. Depending on the department, physical fitness tests may be administered on the same day as your entrance exam. Answer questions presented by police officers in an interview-setting. Expect questions that are normal to job interviews (such as “Why are you interested in this job?”) as well as questions designed to test your ability to remain composed in a high-pressure situation. Answer all questions truthfully. Remain calm. Prove both your honesty and your ability to keep a level head under intense scrutiny.  Since the oral board may come after the background check, any discrepancies between its results and your job application may come to light now. If you were trying to hide any misdemeanors or such from your past, confess to them now, since your honesty is also being evaluated. Remember the Kobayashi Maru from Star Trek. There is often no correct answer to the question you’ve been asked. The focus here is primarily to see how you handle yourself in uncertainty. For the psychological test, complete a written test and be interviewed by a psychologist assigned by the department. For the physical test, provide blood and urine samples for testing. Submit to a physical. Depending on the department’s resources, this may be a standard procedure on par with those performed for eligibility in high school sports, or they may be more extensive, incorporating more high-tech tests. Face further questioning by even higher ranking officers than those on the oral board. Be confident in that you’ve made it this far, since so many other candidates will have been eliminated by now. However, this is your last opportunity to convince them that you are the most ideal candidate, so present your best self. If your department requires you to attend its own police academy after the hiring process, complete the course. Afterward, begin training with a field training officer. Receive verbal instruction and modeled behavior from the FTO before entering the field. Then observe the FTO in action in the field. Expect this period to last anywhere from three to twelve months before receiving the FTO’s endorsement for you to become a full-time officer in your own right.
A: Fill out an application. Take the entrance exam. Complete the physical fitness test. Face the oral board. Submit to psychological and physical examinations. Complete the executive interview. Attend the academy and train in the field.

Q: If your pimple is especially large and painful, or won’t go away with home treatments, see your doctor. She can diagnose any underlying causes and may be able to provide you treatment to more effectively reduce the pimple. You can see your regular doctor or a dermatologist for the pimple. Your doctor may suggest a cortisone injection for a large or painful pimple. This can quickly reduce inflammation and promote healing.  A cortisone shot may cause some pain or discomfort. Your doctor can use a local anesthetic to numb the area before he injects the pimple.  You may notice a dramatic and immediate reduction of the size of your pimple following a cortisone shot. Large pimples that are closed, or under the skin, are difficult to remove without the help of a doctor. A recent study showed that a simple surgical procedure to remove the pimple at its base using medical cautery and forceps can effectively reduce or remove a large pimple. You will need to visit your doctor for this procedure, which may cause some pain and healing time. This is done only rarely for severe or stubborn cases.
A: See your doctor. Inject cortisone into the pimple. Undergo surgical extraction.

Q: Mortar and pestles are usually made in a matching set. The mortar is a small bowl and the pestle is a wand with a curve that's perfectly shaped to grind smoothly against the mortar. The instrument may be made from wood, stone or ceramic, and you'll want to choose your material based on your culinary needs and personal preferences.  Ceramic mortar and pestles are capable of grinding spices very finely, but they're also more fragile than other types.  Wood mortar and pestles are durable, but they're also slightly porous, and subject to stains. It's also possible for the flavor of one spice to stay present in the mortar between uses, tainting the flavor of the next spice you grind. Stone mortar and pestles also grind very finely, but unless they're conditioned properly, fine particles of stone can get ground into the spices. Do you want to crush large amounts of spices, seeds, and nuts, or only small amounts? You will find varying sizes from palm size to bowl size, and it may even be handy to have two different sizes if you have the space and budget for it. If you plan to grind a very large amount of spices, getting a spice grinder may be more suitable for your needs. A mortar and pestle is best for just enough spices to create whatever dish or spice mix you immediately want to use.
A: Pick the right material for your needs. Choose the size you want.

Q: If you have 3 microtubes, you could create 3 balance tubes and situate the 3 pairs across from one another. Alternately, balance the centrifuge without using balance tubes by positioning the 3 microtubes at 2 o’clock, 6 o’clock, and 10 o’clock. The clock positions work well when balancing a 12-hole centrifuge. Other common sizes include centrifuges with 24 and 30 holes. To balance the centrifuge using 5 microtubes, first fill 1 balance tube with water. Then position 3 tubes at 11, 12, and 1 o’clock. Position the other 3 tubes at 5, 6, and 7 o’clock. The balance tube can be located in any of these positions. Balance the centrifuge with 6 microtubes using the same configuration, but swap out the balance tube for a sample-filled microtube. Place 2 sets of 4 microtubes in a way that the sets will counterbalance one another and center the weight in the centrifuge. Place 4 microtubes (including the balance tube) at 11, 12, 1, and 2 o’clock. Then place 4 more microtubes at 5, 6, 7, and 8 o’clock. You can balance a centrifuge using 8 microtubes in the same configuration. Just replace one of the microtubes with a sample-filled tube.
A:
Balance 3 microtubes by placing tubes at even intervals. Position 5 microtubes with 1 balance tube. Situate 7 microtubes and 1 balance tube in the centrifuge.
