Do you know someone who seems to deal with a stuffy nose all winter long? Is it you? Sometimes it seems like the winter months and a stuffed-up nose go hand-in-hand. Contrary to popular belief, cold weather itself doesn't cause a stuffy nose but rather, the conditions that come with cold weather often do. Here are a few reasons why you might have a stuffy nose this winter, and what you can do about it. When membranes inside the lining of the nose get swollen it results in difficulty moving air through the nose. This is the classic definition of a stuffy nose. Sometimes nasal drainage happens alongside a stuffy nose.

Being in a cold environment does not cause a stuffy nose. Rather, stuffiness in the winter is usually the result of getting lots of colds or more active allergies during wintertime. During the cold winter months, people spend more time inside, which means more exposure to dust, allergens, and cold germs. A runny nose might be more common in the winter months, but that too many not be directly related to the season.

If your stuffy nose persists for more than a month (even with medication), or if you have symptoms such as pain, pressure, or fever, see a doctor, as this could be a sign of sinus infection. Open / Comment

Hiccups can be annoying but they’re usually short-lived. However, some people may experience recurrent episodes of persistent hiccups.

At its most basic, a hiccup is a reflex. It happens when a sudden contraction of your diaphragm causes the muscles of your chest and abdomen to shake. Then, the glottis, or the part of your throat where your vocal cords are located, closes. This creates the noise of air expelled from your lungs, or the “hic” sound that feels involuntary with hiccups.

If you find yourself getting hiccups often, eating smaller meals and minimizing carbonated beverages and gassy foods might be helpful. Open / Comment

For most (if not all) people, their voice sounds a lot deeper when they've just woken, compared to how they sound during the day. This effect can easily last for a few hours, like for me today. What are the biological reasons for this? I've heard that it has something to do with relaxation of your muscles during sleep, but I'm not sure how that is supposed to work, and there might be other factors at work.
During sleep while we're in a horizontal position, a certain amount of fluid collects in our upper body (read from the neck up), so our vocal cords will swell and thicken slightly. It's why our eyes look more puffy first thing when we arise. During the night, we're not using our vocal cords either but while breathing, air is still passing over them. So while the tissues swell a little, their outer membrane dries a little. To counter the drying effect, the body secretes more mucous as a protective coat. This effect is much worse in people who are mouth breathers.
Another possible reason is what voice teachers and singers think happens, too. Vocal cords, being muscles, need to stretch and contract to vary the voice's pitch. Unused through the night, they're nit as limber and can't stretch as well as later. Vocal cords stretch to reach higher pitches. If that idea sounds far-fetched, just remember opera singers and other professional singers need to limber up before performing. They practice hours each day but before a performance, they need their voice to be at its best. Hence they'll practice singing notes up and down the scale. Open / Comment

As part of the front and/or rear axle assembly, the differential plays an integral role in how your car makes turns. The differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. This function provides proportional RPMs between the left and right wheels. If the inside tire rotates 15 RPM less in a turn than going straight, then, the outside tire will rotate 15 RPM more than going straight.
For example, when your vehicle goes around a corner, the wheel on the outside must travel faster than the wheel on the inside. The differential distributes equal amounts of torque to both wheels. This permits the wheels to react to resistance, or provide traction, to give the wheel more resistance to rotate less. The wheel with less resistance rotates faster.
Some vehicles, such as go-karts, are not equipped with a differential. In this case, both driving wheels are forced to rotate at the same speed, usually on a common axle driven by a simple chain-drive apparatus. Front wheel drive vehicles are designed differently in that the axle and differential assembly is located in the transmission axle assembly or transaxle. Open / Comment

A Musical Fountain, also known as a dancing fountain, is a type of animated fountain for entertainment purposes that creates an aesthetic design (including three-dimensional images). This is achieved by employing the effects of timed sound waves and timed light (including laser) against water particles. Modern day fountains employ a computer controlled pneumatic arrangements, essentially a pressurized cylinder of water with the provision of an expulsion mechanism(like a piston) and a nozzle at the outlet that are programmed to squirt water with a specific force for a specific duration while the computer also manages the audio output. The circulation system is also modernized with the help of pressure sensors and pumps to maintain continuity. Old school fountains used the principle of siphoning to maintain continuity where the water level was maintained slightly above the height of the canons that squirted water such that any drop in water level resulted in a siphoning suction being established at the canon's mouth.

Each time your engine oil heats up, it evaporates slightly over time, in turn the oil then leaves oil deposits & sludge which constrict the flow of oil throughout your engine making your engine work harder to move the remaining oil around.You can add ann engine flush is added into your engine oil just before an oil change. The flush dissolves sludge and deposits from inside the engine, then drained with the old oil, leaving much cleaner internals than left untreated.
Oil filters can be incredibly effective and can catch particles as small as 10 microns. That being said, there are still a lot of particles located in the engine’s oil stream which are smaller than this and even with a high-quality filter, these particles can’t be removed. Over time, they can build up and cause a noticeable drop in your engine’s performance. Sometimes, simply replacing an engine’s oil won’t get the job done, it is recommended that you change your filter every time you change your oil as this can ensure that your future oil remains cleaner for longer.

There are a lot of different components to an engine and a lot of them need to be properly lubricated when the engine is running. This is where engine oil comes into play.
Over time, your engine oil will begin to collect contaminants and while your oil filter will catch most of this, the oil can still remain contaminated. This results in the engine oil not being as effective, which can cause problems throughout your engine.
Rub your hands together. You’ll notice that your palms begin to get hot, this is due to friction. Now, if you add a few drops of oil (or hand wash) to your hands and do the same thing, less heat will be generated as friction is reduced. Following on from this, place some salt in the palms of your hand. Notice how even though your “oil” is still on your hands, friction is still being created. This is similar to how dirty oil reacts in a running engine. Open / Comment

Engine oils play a crucial part in your engine’s functionality. Without the oil, your engine can become damaged fairly quickly and so it’s in your best interest to make sure that the engine oil is up to par.
The oil in your engine makes sure that the all mechanical components are lubricated to reduce friction, wear and heat. The engine oil ensures that components don’t rub against each other and wear away. While it depends on how often you use your car, older engine oil doesn’t perform as well and so a regular change in engine oil is essential to the functionality of your car. Open / Comment

Biocrystallization is the formation of Crystals from organic macromolecules by Living organisms. This may be a stress response, a normal part of Metabolism such as processes that dispose of waste compounds, or a Pathology. Template mediated Crystallisation is qualitatively different from in vitro Crystallisation.
The main purpose of a Crystallisation in an organic chemistry procedure is to purify the desired compound. Crystallisation also may be used to isolate an solid organic compound from a mixture of compounds in a step in the work-up of a reaction mixture. Open / Comment
