In one sentence, describe what the following article is about: Benzoyl peroxide is the active ingredient in many topical acne medications, such as Benzac and Acne 10 Gel, among others. Acne medication containing benzoyl peroxide comes in many different forms, such as gels, bar soaps, lotions and facial washes. Some of these medications are available over-the-counter, while others require a prescription. Make sure you read the active ingredients of the product to know if it contains benzoyl peroxide and what strength. Benzoyl peroxide works as an antimicrobial and exfoliative agent, helping to kill bacteria and to increase skin turnover. Benzoyl peroxide also helps to dry excess oil on the face. It also works to reduce inflammation where it is applied. It is known that 1 – 2% of people are allergic to benzoyl peroxide.  While most people will experience skin irritation, redness and scaling with the use of benzoyl peroxide, these side effects should subside with time. If you continue to experience redness and scaling even when using very low concentrations applied on alternate days, you may be experiencing an allergic reaction to the drug.  Irritation is extremely common during the first three weeks of use and should improve after four to six weeks.  Other possible signs of an allergic or negative reaction include peeling, sensitivity, and dryness.  If you experience signs of a severe allergic reaction, including a tightness in the throat, shortness of breath, wheezing, low blood pressure, fainting, or collapse, call emergency services immediately. Whenever you use an over-the-counter product containing benzoyl peroxide, you should use that product in accordance with all of the instructions on the label. If you acquired the medication with a prescription, it is critical that you use benzoyl peroxide products as directed by a medical professional. In severe cases of acne, it is common to combine using benzoyl peroxide with topical or oral antibiotics as well as tretinoin.  It should be noted, however, combining benzoyl peroxide with other irritants, other skin care products with benzoyl peroxide or exposing yourself to excessive sunlight can increase the risk of skin irritation in the area where benzoyl peroxide was applied. Make sure to limit exposure to other irritants so that you can effectively gauge the efficacy of benzoyl peroxide products in treating your acne. The side effects of combining other skin care products with benzoyl peroxide are similar to those that occur when you are having a genuine allergic reaction.
Summary: Know the uses of benzoyl peroxide. Know how benzoyl peroxide works. Identify the signs of an allergic reaction. Use only as directed. Limit exposure to other products.

Trace out a circle on 2" plywood and then cut it out with a jigsaw. A diameter of 12" is recommended. Trim three 2" diameter dowels rods to the height you want for your stool. More than 20" is not recommended for this particular design. Using a compass, draw a circle on the underside of your seat that is 9" across and centered. Divide the perimeter of the circle into thirds. Then drill 1 3/4" holes into the seat at an angle. The easiest way to do this is to place a 1" block underneath half of the seat so that it sits at an angle and then drill straight down. Adjust the height of the block to change the angle the legs will be at. Experimenting before making this stool is a good idea. Use a shaver, sandpaper, a router or other tool of your choice to trim the top 3" of the dowel down to 1.5" wide. Then, glue and insert them into the holes. Trim and sand down the pieces which stick above the surface of the seat until the top of the seat is flat and ready for sitting on. You can paint or stain your stool if you want to. Otherwise, it's ready for use!

Q: Break down the total duration of the class into the key topics to be covered, or units. Each one of these sections should account for a fundamental lesson to be learned at a specific interval of the term in order to fulfill the curriculum requirements. These unit plans should cover either a week or a month of study and together, form an organized sequence of learning for students.  For instance, in an introductory Anthropology course, you might plan a week-long unit entitled “The Agricultural Revolution” during which you will teach students about the origins and rise of farming. When planning the schedule, make a point of noting all upcoming events and conflicts that will interrupt a straight-forward, linear scheme of work. Look through a calendar to mark down statutory holidays, and through a school calendar to take note of any school breaks, examinations, or assemblies that will interrupt normal class time. Allow time for review and practice in the event that students have trouble grasping course material and need more time to absorb it. For example, a unit like WWII in a 20th century history course might be stretched over two weeks instead of one week to accommodate a statutory holiday, and allow for review to ensure that all students are well-versed in this important component of the class. Consult with colleagues to ensure that there are no major conflicts with your schedules. For example, avoid scheduling a major assignment on a day that your students will have a midterm exam in another class. Advise teachers of your prospective dates for exams and major projects.
A: Break down the duration of the course. Factor in scheduling interruptions. Work around other teachers' schedules.

Problem: Article: While in the shower, rub a piece of lemon or lime over the skin that most likely has deposits of vapors from cooking such as hands, face, and arms. The acidity in lime will help to break down the essential oils that cause the lingering curry smell. Finish by washing with soap and water as usual.  Be sure to avoid open cuts or wounds on the skin as this can cause painful stinging or burning. Avoid putting on any of the same clothing articles that were used while cooking, for instance a hat or sweater. You can try using air diffusers, air deodorizing sprays, plug-ins, or scented candles. Also of great use are air fresheners that allow you to spray on fabrics. Spray all items that are in the cooking vicinity until damp, such as the carpet, upholstery, drapes or walls.  A combination of many products will work well. Be sure to carefully read instructions on the packaging label to ensure proper use. Put two cups of water in a pot on the stove and bring it to a boil. Add fragrant materials such as Kewra (Screwpine) leaves or vanilla beans/extract, and turn the heat down to a simmer. Allow it to simmer for at least one hour. The smell emitted will mask the lingering curry odor.  Screwpine leaves are also known as pandan leaves and can be purchased at the local Asian grocer or specialty grocery store.  There are no set specifications on how much screwpine or vanilla you should add. Try a few sprigs to begin with and add as needed. You can also try boiling other fragrant ingredients you have to get rid of the smell, such as 3 cups (720 mL) of white vinegar, 1 cup (240 mL) of water, and 6 cinnamon sticks. Open the windows for a day or two to allow fresh air to permeate through the residence. You may also need to replace filters in your heating or cooling systems so they don’t circulate odorous air.
Summary:
Wash your face and hands with lemon or lime. Use air freshening products. Boil flowers or leaves that emit a pleasant fragrance. Allow fresh air into your home.
