Article: Be on your absolute best behavior, especially for the first few weeks of school.  Sit quietly.  Don’t pass notes.  Keep your phone silent and in your bag.  Always raise your hand before speaking.  Put your lab equipment away properly.  Ignore the lovebirds whispering sweet nothings to each other behind you. Don’t test the rules to see what you can get away with.  Let some other kid do that.  Focus on impressing your teacher with your knowledge of and adherence to the classroom rules.  This demonstrates maturity, respect, and diligence. Don’t let yourself think that others’ conversations or hijinks give you license to do the same.  Keep your primary goal — learning — in mind.  Brush aside distractions, and never become a classroom distraction yourself. You will be a distraction, and you won’t be ready to learn, if you show up late to class.  Do everything you can to make it to class on time, if not early.  Unless you have a truly legitimate reason for being late, don’t try to make excuses.  Be as discreet and quiet as possible as you take your place in class, and give an apologetic look to your teacher. attentively to your teacher.  How do you know when it is important to pay attention?  It’s a trick question:  it’s always important — if you want to make a good impression!  Having to ask the teacher to repeat something can be embarrassing and indicates that you don’t care enough to give your best effort. If you’re having trouble keeping focused during class, ask to be moved to the front row.  This is especially helpful if other students are distracting you, or if you have any kind of hearing or vision difficulties.  Talk to your teacher about other possible solutions if necessary. Nobody wants to be the kid who tells the teacher about every little thing other students do wrong — this is the easy way to get labeled the ”teacher’s pet” or a “snitch” by your classmates.  So, yes, use your judgment in deciding what to report and what to let slide.  But, when you know something disruptive or otherwise wrong is going on, report it quietly to your teacher. Don’t raise your hand and blurt out “Mrs. Magowan, Sam and Max are talking instead of paying attention.”  Instead, wait until after class and discreetly voice your concerns about the distraction they are causing you and others.  If, however, Sam and Max are playing around recklessly with the Bunsen burner, inform your teacher right away.

Problem: Article: Many electric motor failures are caused by bearing failures.  The bearings allow the shaft or rotor assembly to turn freely and smoothly in the frame.  Bearings are located at both ends of the motor which are sometimes called "bell housings" or "end bells". There are several types of bearings used.  Two popular types are brass sleeve bearings and steel ball bearings.  Many have fittings for lubrication while others are permanently lubricated or "maintenance free". To perform a cursory check of the bearings, place the motor on a solid surface and place one hand on the top of the motor, spin the shaft/rotor with the other hand. Closely watch, feel, and listen for any indication of rubbing, scraping, or unevenness of the spinning rotor. The rotor should spin quietly, freely and evenly. A small amount of movement in and out (most household fractional horsepower types should be less than 1/8" or so) is permitted, but the closer to "none" the better. A motor that has bearing-related issues when run will be loud, overheat the bearings, and potentially fail catastrophically.
Summary: Begin to check the bearings of the motor. Perform a check of the bearings. Next, push and pull the shaft in and out of the frame.

There are family cord blood banks in countries throughout the world. You can ask your doctor or hospital to direct you to a private bank with a good reputation, or you can look on a directory of private blood banks and do your own research on those you find.  The Parent's Guide to Cord Blood Foundation has a worldwide directory of family cord blood banks, which you can browse for free.  Note that cost is not necessarily an indication of quality. Some less expensive blood banks might be cutting corners in potentially unsafe manners, but others might have lower costs simply because they spend less on marketing. Reputation is usually a better indication than anything else. You should also check on the qualifications and experience of those running the blood bank, as well as the company's viability, stability, and storage technology.  Shop around. If one blood bank can't offer you a discount, call another. It may take awhile to find the best rates for your financial situation. Once you find a private blood bank you want to work with, you should contact them and make arrangements. You should also make sure that your doctor and hospital are aware of these arrangements at least one month before your baby is born, if not sooner.  The company you've chosen to bank with should send you a collection kit. You must give this kit to the hospital or birthing center at the time of delivery. Even though the hospital will not receive the kit until delivery, you should still make them aware of your intentions beforehand.  Make sure that cord blood is collected after delivery. Doctors and nurses should collect the blood from your baby's umbilical cord within a few minutes after the birth of your child. Each private blood bank has its own procedures, but when your family needs the cord blood stored at the bank, you should be able to notify the bank and have the blood delivered to your hospital for a transfusion. You may need medical authorization from a doctor to show the blood is presently needed. The cord blood will be tested to see whether or not it's a match for the patient.
