Before buying a cosmetic product, most of us tend to swoop down on the counter at the store where we get to try on the testers. However, after we have tied them out, more often than not we end up feeling guilty for three reasons, two of them being that the tester didn’t match out skin tone or texture and we couldn’t apply it well. However, what we overlook is the question as to how hygienic the tester really is. Although it is obvious that we don’t feel satisfied to buy products without trying them out, we certainly would think twice or thrice before trying on eye shadows or lip lipsticks which have been used before. In fact, according to statistics, half of the testers have been discovered to be crammed with Strep and E. Coli bacteria, having been heavily contaminated due to the heavily varied use. One can even get pink eye or a virus like hepatitis. Listed below are some tips before trying testers:
• Be safe, try personal: Popular stores would be ready to prepare personal testers for their customers, especially for products such as lipsticks, going in from dipping and spraying the shade with alcohol. Alcohol Sanitizer wipes are also available these days, with which one could scrape off the top most layer of the product, the used part, and use the unused one below. Trying products with disposable or brushes is also recommended. Sharpening the top layer is also good enough as all the contamination are deposited on the surface layer.
• Don’t try anything open: Don’t try anything or everything that comes in an open pot or jar. Most people out of fascination dip their own fingers into the product and try it out on their faces, such as face lotions, lip gloss or loose powdered eye shadow. Disposable cotton bud or pads are good to go.
• The trying areas: For the cheeks products like foundation, blush or face glitter, always use the back of your palm as the testing place and now your cheeks or the jawline. Don’t try any eye makeup either, such as pencil eyeliners or kajal – use the back of your hand for that too. This area also helps you identify how soft the bristles are by just drawing fine lines on your skin. If you really want to try on eye products, sanitize the tip with clinical alcohol. Unless and until the sale staff offers you clean fresh sample testers, do not indulge in putting anything on your face. Chances of infections such as zits is very high.
• Days of the week: Try visiting cosmetic stores on weekdays because weekends are too crowded for the staff to be paying complete attention to what kind of testers they’re giving you.
Be smart and follow these tips to stay safe from infections from testers.

History of mathematical symbols
Read moreThe history of mathematical notation includes its commencement, progress and further cultural diffusion. There were conflict of methods of notations. The history includes multicultural and lingual including Roman, Greek, Hebrew, German, Hindu, Arabic and German alphabets. These host of mathematical symbols were developed in the due course of centuries. The ones that gained popularity are the ones you see in today’s world (original notations might still be used in the native grounds that they originated from).
The development of mathematical notations can be divided into stages that have been listed below.
Rhetorical stage
The rhetorical stage is where calculations were performed by words and there were no use of symbols. The rhetorical stage had mathematical notations that were based on distinctive features like symbols having local as well as intrinsic values. The mathematical notations originated from the real world problems even before the underlying rules and concepts were identified and defined as abstract structures. Geometry, for example, has its origin from calculating the distances and areas in the world. The Egyptians had symbols for basic operations. Legs going forward represented addition, and legs going backward meant subtraction. People from Mesopotamian had symbols for each power of ten. They are one of those cultures that wrote their numbers just like it is written in the modern times. For example, instead of having symbols for higher notation of a degree of number, they would just put the coefficient of that number. By the year 800 BC, they had created a symbol for zero and it acted as a placeholder.Syncopated stage
Plato’s work has been strong especially in the field of mathematics. His work helped distinguish between pure and applied mathematics. The Greek mathematics refined the methods by introducing deductive reasoning and expanded the subject matter of mathematics.The Milesian numeration
The Greeks employed a mathematical numeration which was based on system of the Egyptian. It was later adapted by Romans. The Greek numerals denoted four as four vertical lines. The symbol to denote number five was the symbol (pi) for the Greeks. Ten was represented by a triangle and the word for ten was Deca (hence the name decimal). -
Pneumonia – Causes, signs and treatments
Read morePneumonia is a bacterial infection that takes place in the lungs. Various symptoms of Pneumonia are visible and may even require immediate hospitalization so that the patient may be treated under intense and appropriate medical care. Yet, for many people, the condition may be treated at home if the bacteria have not progressed to a great degree at the time of diagnosis. The condition is known to clear within a few weeks, but it may give rise to complications for those who are already suffering from other diseases.
There are many causes of pneumonia. The top reason is exposure to very low temperatures. Let us find out more about causes of Pneumonia along with the measures that may be taken for diagnosis and treatment.
• Causes of the bacterial infection: Pneumonia is a bacterial infection which is caused by the bacteria known as pneumonia. When we breathe in germs which enter our lungs, this bacteria gets activated. This happens during extremely low or cold temperatures when we do not have enough of protective layers of clothing on us. This leads us to start breathing from the mouth, which clears the way for germs to enter into the lungs. It may also happen when a person already has had a cold and flu. This can trigger the growth of the pneumonia bacteria, which can lead to the infection as well.
• Implications: Pneumonia can leave your immunity in a bad condition and therefore, you will not be in the state to fight the onset of further infections. Also, for those who are already suffering from chronic diseases like diabetes, cancer, and heart disease, the condition may get worse. Further, patients who are suffering from such kind of chronic diseases are at a far greater risk of contracting the disease as their immunity is already at an all-time low.
• Symptoms: Pneumonia comes with a number of symptoms. One of the earliest signs of the infection is a persistent, racking cough. Also, the patient will experience chills and accelerated heartbeat. Nausea, vomiting as well as loose motions will be experienced by the patient. The patient will also feel a lot of fatigue. Chest pain is also another common symptom that comes along with the coughing.
• Diagnosis: The diagnosis will be conducted with the help of an X-Ray and other tests like complete blood count or CBC. The mucus from the lungs may also be extracted and tested in order to determine the existence of the disease.
• Treatment: There are many measures that will be taken in order to treat the infection. To begin with, the doctor will prescribe antibiotics that must be taken regularly. Also, it is imperative that one should not stop taking them but finish the full course. Not completing the course of antibiotics may lead to a relapse of the condition. Further, the patient will need to take complete rest and get lots of sleep so that the body’s energy may get replenished. Also, a proper diet with plenty of hot liquids is be prescribed for the patient.
