Been burning the candle at both ends like Effie? (Picture: Channel 4) ItБs a day of the week so weБre feeling a little fatigued. And weБre already battling those pesky dark shadows under our eyes. But why do we get dark circles under our eyes when weБre knackered? First up, itБs important to note that dark circles and eye-bags are two separate things, although they often appear in tandem. Dark circles Dark circles are down to genes as much as lack of sleep. The skin underneath your eyes is thin and covers muscles, fatty tissue and blood vessels. Dark circles are the result of light being reflected back from blood vessels sitting just below the skinБs surface. How dark that area is has a lot to do with skin colour and thickness. As to why theyБre more prominent when youБre tired, itБs
There are a number of different types of plate boundary. A destructive plate boundary is sometimes called a convergent or tensional plate margin. This occurs when oceanic and continental plates move together. The oceanic plate is forced under the lighter continental plate A section of the crust that makes up the Earth's landmasses. Friction causes melting of the oceanic plate and may trigger earthquakes. Magma rises up through cracks and erupts onto the surface. An example of a destructive plate boundary is where the Nazca plate is forced under the South American Plate. ...
Imagine you are trying to find out how much an elephant weighs. You are pretty sure it weighs a lot, but you don't know the exact number. So you ask your teacher, and she tells you an elephant weighs the same as three hippopotamuses. Well that's nice to know, but how much does a hippopotamus weigh? Again, you ask your teacher, and she tells you a hippopotamus weighs the same as five alligators. That's a cool fact to know, but you still don't understand how much an elephant weighs because comparing elephants to alligators can be confusing. To avoid confusion when measuring, scientists use a shared system of measurement, called the International System of Units (SI). 'Unit' is the word used to describe how something is measured. ...
Salt enhances flavors. The magic of salt is that it unlocks already-present flavors, making them stand out. In essence, it makes food taste more like itself. This is why we put it in pretty much everything we eat, including sweet things. Some people find that a touch of salt will bring out interesting flavor notes you wouldnвt otherwise notice in your morning cupвalthough sometimes, those characteristics may only serve to make you realize that you need to buy better coffee. Salt improves the water. People are fond of saying that your coffee is only going to be as good as your water. If you have hard water or the water you are using to brew coffee is less-than-fresh because itвs been sitting in your coffee makerвs reservoir all night, your coffee might end up being subpar. However, if you
There are a lot of wonders in the world and among them are wildlife species, such as bears, mountain goats, wolves, elk, and deer. Most people think that there is an abundance of wildlife species in the world, but the truth is, their numbers are dwindling and if nothing is done about it, these species might become endangered and extinct. Animals become endangered all the time and people are not aware about it. Thankfully, more and more preservation programs have been established to ensure that these animals are protected, bred, and well-taken care of. These preservation programs motivate and increase the awareness of the public regarding the proper management of natural resources. What Is Wildlife Conservation? Wildlife conservation is the attempt to protect endangered animal and plant
БThe war is over. Б Б Secretary of Defense Donald Rumsfeld in Afghanistan (April 2002) БI believe victory is closer than ever before. Б Б Vice President Mike Pence in Afghanistan (December 2017) WASHINGTON Б With metronomic regularity, every thousand days or so, Americans should give some thought to the longest war in their nationБs history. , which is becoming one of the longest in world history, reaches its 6,000th day on Monday, when it will have ground on for substantially more than four times longer than US involvement in World War II from Pearl Harbor to V-J Day (1,346 days). America went to war in Afghanistan because that not-really-governed nation was the safe haven from which al Qaeda planned the 9/11 attacks. It was not mission creep but mission gallop that turned the
Fingernails are made by living skin cells in your fingers. So a skin condition such as may lead to fingernail ridges. can also cause these ridges. If your body is low in protein, or vitamin A, a deficiency can sometimes be revealed by ridges in your fingernails. Vertical ridges are furrows that run from the tip of your fingernail down to the cuticle. They are sometimes called longitudinal striations or bands. Slight vertical ridges in fingernails often develop in older adults, possibly due to a slowing of cell turnover. This is when new skin cells produced below the surface of your skin rise up to take the place of dead cells that are discarded from the surface. If you experience other symptoms like color or texture changes in your nails, it may be caused by a medical condition. ...
In a paper published in 1894, it was formally proposed to add chlorine to water to render it "germ-free". Two other authorities endorsed this proposal and published it in many other papers in 1895. Early attempts at implementing water chlorination at a water treatment plant were made in 1893 in, Germany. In 1897 the town of, England was the first to have its entire water supply treated with chlorine. Permanent water chlorination began in 1905, when a faulty and a contaminated water supply caused a serious typhoid fever epidemic in, England. Dr. Alexander Cruickshank Houston used chlorination of the water to stop the epidemic. His installation fed a concentrated solution of so-called chloride of lime to the water being treated. This was not simply modern calcium chloride, but contained
The most scientifically backed theory about why we yawn is brain temperature regulation. A published in Physiology Behavior looked at the yawning habits of 120 people and found that yawning occurred less during the winter. If the brainБs temperature gets too far outside of the norm, inhaling air can help cool it down. You may also find yourself yawning more if you get migraines. During a migraine, your blood clots in your brain. Yawning helps to cool your brain down from that clotting. Another reason you may yawn is because the body wants to wake itself up. The motion helps stretch the lungs and their tissues, and it allows the body to flex its muscles and joints. It may also force blood toward your face and brain to increase alertness. Mark A. W. Andrews, associate professor of
Praise and Worship - A Natural Desire Praise and worship seems to be universal. Have you ever heard of an explorer finding a new tribe or culture that doesn t worship? Worship is a natural instinct and a basic need for every person. A simple definition of worship is to regard with great devotion or to honor as a divine being. Take a second to think about what you are most devoted to in this life and ask yourself, "Is it worthy of my devotion; do I worship a divine being? " We don t all worship the same God, but everyone worships something or someone. Since we all worship, we should question the reason for this desire. The most logical conclusion is that we were created by a higher being for the very purpose of worship. The ongoing quest of man is to find answers to the fundamental
