			<content:encoded><![CDATA[<p>The symbol of a gun behind held to the side in a threatening manner is iconic of many “gangster” groups existing throughout the world today, with a large number of aspiring music artists particularly in the rap genre taking on this image to establish themselves in the eyes of their followers. While this may seem to be a well-established trend amongst many individuals the fact of the matter is that is not in fact an effective way of utilizing a gun at all – in fact it is dangerous, inaccurate and otherwise un-recommended by any effective shooter in virtually any situation.</p>
<p>The popularity of the sideways gun hold can actually be tracked back to Hollywood, with the 1993 movie Menace II Society showing this grip in the opening scene and poularizing it with viewers at that time. Before then it appeared in a number of other movies as well, including the Clint Eastwood western “The Good, The Bad and the Ugly” – most likely to allow camera operators to get the best view of both the gun and the character’s face in the same frame without obstructing any views.</p>
<p>In terms of actual functionality the sideways grip both reduces overall accuracy and makes the weapon more dangerous to both innocent bystanders and the actual operator him or herself. With accuracy in mind the sideways angle makes the weapon extremely difficult to aim, causing the standard “iron sights” at the top of the gun normally used for aligning the aim to become effectively useless. This position, in turn, makes the gun a danger to all individuals who may be in front of it at the time (which isn’t necessary for most shooters in gun fights as studies show that roughly 60% of all modern-day gunfighters never aim while shooting). Interestingly enough, however, this hold IS used by law enforcement officers holding shields as the sideways aim actually allows them to have greater accuracy while behind a shield, bringing the sights into their line of sight better than if held regularly.</p>
<p>Additionally when this position is used with most semi-automatic pistols today the ejection chamber is located on the right side of the gun. If used by a right-handed wielder and rotated counter-clockwise the ejection chamber rotates upwards, ejecting hot bullet casings out of the weapon and many times directly at the face of the wielder – making it extremely dangerous for individuals to hold the gun like this for even the shooter unless they feel like dodging hit metal every time they take a shot.</p>

			<content:encoded><![CDATA[<p>Laughter is one of the most basic forms of communication that human beings (and even some animals, in a sense) use to communicate their current emotional or mental state to others around them at a subconscious level. This is a form of communication that is also purely occurring at a subconscious level, with consciously produced &#8220;forced laughter&#8221; registering as insincere or grossly unrealistic to listeners. On the other hand, however, this urge to respond to external stimuli can be suppressed by a conscious effort to do so &#8211; though depending on the situation this may be a difficult task to accomplish at best.</p>
<p>Through years of study into human laughter scenarios scientists have concluded that the causal effect of laughter is not necessarily from a funny situation and instead stems from our root desire to communicate with others in a way that allows them to interpret humor, pleasure or an otherwise positive response to a statement. This stems back to approximately 3.5 to 4 months of age when most people first develop the ability to laugh in addition to cry as one of the primary forms of communication with their parents and the world around them &#8211; well before conscious language development takes place.</p>
<p>The development of laughter to effectively communicate in a non-verbal manner with others should not be mistaken purely as a way of expressing humor alone, however. In fact, laughter has been seen instead to act as a form of social bonding rather than purely for individual expression. Analysis of when people laugh the most, for instance, has shown that individuals are more likely to talk to themselves while alone than laugh while alone and join in with other laughter should they be in a social situation where the majority of individuals are laughing (and as such the term &#8220;infectious laughter&#8221; has come about).</p>
<p>Researchers have further noted that laughter is also both used in positive and negative social bonding experiences, with people &#8220;laughing with&#8221; and &#8220;laughing at&#8221; someone or something in order to both develop a group bond as well as either force another individual into group conformity or to exclude them from the primary group &#8211; a survival instinct where large numbers matter most. This is particularly common in relaxed social atmospheres and becomes less common as people mature and &#8220;play&#8221; less, with children approximately 5 and 6 years old laughing the most with each other and adults laughing the least.</p>

			<content:encoded><![CDATA[<p>Many animals in the world are known to develop a glassy “glare” of various colors at night should a light be shined into their eyes, with some of the most common examples of these being cats, dogs, deer and other animals living a highly nocturnal life. This glare in generated from a layer located within the eye itself known as the tapetum ludicum that acts as an organic mirror of sorts to reflect light waves back out of the eyes – thus generating the glare seen when a light is shown into the eyes of these animals when it is dark and not at other times.</p>
<p>The purpose of the tapetum ludicum is to reflect light waves that filter entirely through the eye back out of the eye in order to allow for a second chance at detection by visual receptors. This process increases the overall effectiveness of eyes in low-light settings and thus enables animals to remain more functional in nocturnal environments.</p>
<p>Unlike these animals, however, human beings do not possess a tapetum ludicum within their eyes, thus no light is generated when a standard light bounces into a human’s eyes in a low-light environment. A high-intensity camera flash, on the other hand, is a different matter. Generating a powerful-enough burst of energy and capturing the resulting light waves in an aperture immediately after the light is generated creates a reflection to be generated off of the standard pupil of the eye. The resulting reflection is what is captured in a photograph, with the red color coming from the reflection of blood vessels within the eye.</p>
<p>Because the “red eye” of humans is generated by a reflection of blood vessels within  the pupil necessary for eye function the red-eye reduction capabilities of modern portable cameras works to reduce this by taking pictures with a double-burst of light. The first flash generates a strong enough light source to cause a contraction of the pupil and thus significantly reduce the overall possibility of reflection from occurring, while the second burst is used to provide luminescence for taking the photo itself. Alternatively flashes can be bounced off of nearby walls or light generated from an alternative angle as well in order to cause the reflection to move away from the camera rather than be returned directly into the camera’s lens, thus removing the glare from human eyes (though unfortunately not that of many animals possessing a highly reflective tapetum ludicum as this will return light from virtually any angle in a dark setting).</p>

			<content:encoded><![CDATA[<p>Whether due to hunger or at any other time during the day, a human stomach can make any number of different noises with virtually no warning and in some cases potentially embarrassing side effects. The reason for these sounds to occur in the form of a growl, roar, whine or however else the side might be emitted at the time and generally accompanied by a rumbling sensation in the chest lies in basic human biology.</p>
<p>The stomach is one of the key parts of the human digestive tract, or essentially one large channel beginning at the mouth and ending at the anus that is used to digest and process nutrients throughout our days in order to provide fuel for the rest of our body to function. When hearing (and often feeling) a &#8220;rumble&#8221; this is the result of an action taking place within the stomach and generally the first part of the small intestine as well.</p>
<p>Beginning a few hours after the stomach has emptied itself of food a signal is sent to the brain to prepare the body for additional food intake and initiate a &#8220;hungry&#8221; sensation. To do this a series of muscles throughout the digestive tract activate in order to clear out any residual food that may be remaining within the stomach and intestine to prepare for new food to be processed. This forces any air, liquid or other solid matter deeper into the digestive tract for processing though a series of quick muscle movements generating the &#8220;rumbling&#8221; sensation felt when a growl occurs and generating sound from the propulsion of the matter through the digestive system.</p>
<p>The muscle contractions have a secondary effect on the body as well aside from simply preparing the body for additional food intake. By rapidly contracting the muscles around the stomach the body activates another base signal to generate hunger and the desire to consume additional food. For this reason the strong desire to eat something &#8211; even just a small snack &#8211; will always come on strong right after growl is heard or felt.</p>
<p>Sometimes, however, these vibrations are not the result of hunger alone but a byproduct of the body&#8217;s processing of gasses trapped within the stomach. As the gas bubbles pass from one chamber to the next the regularly contracting muscles of the stomach cause a sound to be generated and additional muscle spasms to occur. For this reason preventing hunger alone may not be the only way to prevent these sounds from creeping up on you at any time and avoiding particularly gassy foods (such as carbonated beverages) may be a good idea desirable as well.</p>

This forces any air, liquid or other solid matter deeper into the digestive tract for processing though a series of quick muscle movements generating the &#8220;rumbling&#8221; sensation felt when a growl occurs and generating sound from the propulsion of the matter through the digestive system.</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">The muscle contractions have a secondary effect on the body as well aside from simply preparing the body for additional food intake. By rapidly contracting the muscles around the stomach the body activates another base signal to generate hunger and the desire to consume additional food. For this reason the strong desire to eat something &#8211; even just a small snack &#8211; will always come on strong right after growl is heard or felt.</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">Sometimes, however, these vibrations are not the result of hunger alone but a byproduct of the body&#8217;s processing of gasses trapped within the stomach. As the gas bubbles pass from one chamber to the next the regularly contracting muscles of the stomach cause a sound to be generated and additional muscle spasms to occur. For this reason preventing hunger alone may not be the only way to prevent these sounds from creeping up on you at any time and avoiding particularly gassy foods (such as carbonated beverages) may be a good idea desirable as well.</span></p>

			<content:encoded><![CDATA[<p>Whether tennis, table tennis, baseball, football or golf, all of these sports share one common feature among them: when hit with enough force in a certain way the balls used in them can adjust their trajectory mid-air and fly in any number of curved paths between their point of origin and their destination. This is due to a number of physical features that exist within the balls and can, in many ways, be controlled to your advantage both in these sports and others like them.</p>
<p>The primary reason for this adjustment in direction is due to the fact that the ball&#8217;s spin, as it flies through the air, creates a pocket of air with an adjusted density in one particular direction. A ball with a high backwards spin, for instance, creates a pocket of lower density sir above it that allows it to appear to even hover at times as the velocity allows for the air above it to be displaced and create an upward lift. Even at relatively low velocities this can occur, and can be seen even when tossing a small fruit in their air with a slight spin on it.</p>
<p>In many ways this is the same way that modern airplanes function, with wings specially designed to increase the speed of airflow over them while maintaining a set natural speed below in order to create a lifting force that allows for flight. By applying enough force to a ball and generating enough rotation speed in the process this effect can be quite pronounced even over short distances.</p>
<p>By the same function this effect can be used for more than just lift, however. By adjusting the rotation of the ball to either side the pocket of lower density air created by the high speed rotation can be forced to shift in any particular function, thus forcing the ball to travel in any number of desired ways.</p>
<p>Baseball pitchers are particularly accustomed to this phenomenon and actively apply it to many of their throwing styles in order to create varying degrees of curves in each of their throws and thus confuse a batter. Much in the same way do tennis players adjust the spin on the ball they hit in order to add a level of control to the court and confuse their opponent as well as prevent many successful returns from being completed due to the increased difficulty presented through the spin of the ball.</p>

			<content:encoded><![CDATA[<p>The dawn of my academic career was spent in Madagascar. Although I was completely take aback by the intrinsic beauty of the small island nation, my goal was to study the island&#8217;s significant chameleon population. The island is home to about half the world&#8217;s 150+ chameleon sub-species and provided an ideal environment to answer an age-old riddle that puzzled generations of the world&#8217;s great thinkers: what colour does a chameleon turn when sitting in a mirrored box? </p>
<p>After returning to a provincial university and presenting my results to much acclaim amongst my peers, I spent a prolonged period in the United States. I travelled extensively through all 36 states that use the lethal injection as a method of execution, studying all prior execution cases and autopsy reports. An extensive work was presented to the Royal Society at the end of my American sojourn. Our ground-breaking study concluded that not a single executed inmate showed any signs of fresh infection from hepatitis B, hepatitis C, tetanus or human immunodeficiency virus, and so using clean needles for future executions might not be necessary and could potentially save the conscientious, tax-paying men and women of the United States several dollars annually. </p>
<p>Riding the tide of achievement, I then focused my attention on some of the great historical conundrums, particularly why Kamikaze pilots wore helmets. There can be no greater deterrent to a young Kamikaze pilot than frostbite to the tips of the ears. Hurtling in to 20 000 tons of 8-inch armoured plated steel at 400+ mph with frost-bitten ears was a prospect few, if any, of Japan&#8217;s finest airmen could countenance. Mindful of this problem, and anxious to pamper the nation&#8217;s finest, the Japanese Naval Air Fleet commissioned Italian fashion house Innuendi to design a series of haute-couture, fur-lined helmets for kamikaze pilots. The tailors of Milan were grateful for the work and hastily delivered the luxury headgear much to the delight of young kamikazes and their naval commanders.  </p>
<p>Twistleton-Moncrieff and Hoffman (1993) suggest the reason was pecuniary rather than related to pilot comfort. They studied documents recently released by famed insurers Lloyds of London. Lloyds underwrote the Japanese Air Force throughout World War II. Small print of the documents signed by Chuichi Nagumo of the Japanese Naval Air Fleet show a health and safety rider added by Lloyds stating individual claims can be nullified if the pilot is not “wearing a helmet that comports with recognized standards”. </p>
<p>The TMH findings coincide with later Innuendi order dockets which show headgear shipped after January 1945 were strengthened to comply with Japanese Air Fleet standards. A third suggestion was that towards the end of the Pacific conflict, having seen many of their colleagues needlessly puree&#8217;d and scraped off of the upper decks of US destroyers, pilots were getting a little jittery about confronting the same fate. Small ear-pieces were then discreetly fitted in to later revisions of the Innuendi helmets. Through these ear-pieces, Naval Fleet commanders ensured pilots did not fall short of their targets. </p>
<p>The real reason? Well, we&#8217;ve yet to conclude our full survey on the matter, but a conclusive paper should be put forward for peer review by the end of the summer.</p>

			<content:encoded><![CDATA[<p>With the 2010 World Cup under way, one country sure to stand out through both orange-vested players on the field, and multitudes of orange-clad followers in the stadiums is the Netherlands. Perhaps no greater association between country and colour exists. But what is the origin of the association between the colour orange and Dutch national pride? </p>
<p>To answer this question we must cast back the years to the turbulent days of 16th century Europe. The old established orders of continental Europe were being challenged, neighbourly disputes between individual nations were common and the rise of England as an overseas contender under the tutelage of the Tudor dynasty all contributed to the flux of chaos on the European continent. To add to the mix, religious reform, and in particular the rise of protestantism was being aggressively persecuted by Catholics who ruled much of Europe. Many in the Netherlands believed the positions of power should be transferred from foreign, mostly Spanish, Catholics to Dutch nobility and that the increasing persecution of Protestants had to be arrested.<br />
By 1566, Protestant groups mounted a backlash against Catholic persecution, destroying statues and holy figures, and eventually leading the then governor, Margaret of Parma, to agree nominally to the petitions of the unhappy parties. </p>
<p>One such party was a large confederacy of lesser noblemen, the so-called Confederacy of Noblemen. Many of these were devout Catholics who also harboured a deep commitment to religious freedom for all peoples. Among the many noblemen of the confederacy were German-born William Prince of Orange (also known as William the Silent) and his brother Louis.<br />
The Governor&#8217;s promises to the confederacy were never fulfilled and as a result of much further violence, many Protestants, particularly Calvinists, fled the country. After supporting the works of the confederacy financially for many years, William and many noblemen found it necessary to flee.<br />
The ruling classes then summoned a council, the Council of Blood, whose judgement was to declare William of Orange and other noblemen as outlaws. </p>
<p>In exile, William raised an army and after a series of alliances and subsequent battles, collectively named the Eighty Years War, managed to successfully overthrow Spanish rule and establish an independent Dutch state.<br />
William&#8217;s eminent place in Dutch history was sealed, as was the place of his dynasty, the House of Oranje-Nassau, also called simply the House of Orange; so much so that the people of the Netherlands adopted orange as their colour, and their nation&#8217;s colour, associating it with Dutch national pride for ever more. On important dates in the royal calendar, such as birthdays, the red, white and blue of the Dutch flag is accompanied by an orange pennant. On Queen&#8217;s Day (Koninginnedag), which occurs on April 30th) each year, much of the country, but especially the capital Amsterdam, turns completely orange as the Dutch celebrate a day of national unity to honour the queen. The Dutch national football team are nicknamed the Oranje. </p>
<p>Members of the House of Oranje continue to play a major role in the nation&#8217;s modern democratic government.</p>

			<content:encoded><![CDATA[<p>The nose is a highly complicated structure that servers a number of purposes for our body, ranging from assisting with the identification of food to helping to protect our body from harmful substances such as foreign objects and various viruses or bacteria. For this reason our nose has a habit of producing copious amounts of liquid known as mucus in any number of cases, ranging from it simply being too cold outside to even working as part of your body to combat an infection. In fact the human nose and sinus cavities produce an average of 1 quart (or approximately 946mL) of mucus each day, not counting other days when our nose goes into &#8220;overdrive&#8221; to protect our body.</p>
<p>For most people the most common causes of a runny nose on a typical day is due to either foreign objects irritating their sinus cavities (such as in the case of allergies) or due to an infection currently being fought off within the body itself. When this happens due to allergies the nasal cavity becomes stimulated by the various pollens in the air, causing the mucus production glands to activate in order to trap any foreign material that may enter into your body and protect your lungs from damage. This mucus may either run out of the nose itself or become trapped in the sinus cavities found throughout your face, resulting in a &#8220;stuffy&#8221; feeling. In similar ways the same happens when we fall ill with a cold &#8211; the mucus activates to fight off any additional bacteria or viruses that may attempt to enter our body in order to allow our body a greater ability to combat the disease and prevent us from falling even more ill.</p>
<p>Aside from simply fighting off foreign objects and bacteria our nose&#8217;s ability to protect our lungs by heating up the external air temperature is also a cause for our nose to run in winter time. When the outside air drops to a sufficient enough level our body activates additional blood vessels in the nose that allow for it to heat up air as it enters our body and protect our lungs from direct exposure. As these vessels expand our mucus production glands activate, causing an excess amount of liquid to drain from our nostrils than we may experience otherwise. For this reason if you wish to avoid having an excessively active nose in the middle of a cold winter be sure to keep your face well insulated, or otherwise be sure to pack additional tissues in order to help keep your sinus cavities clear of any excess mucus buildups.</p>

			<content:encoded><![CDATA[<p>On January 12th 2010, the small Caribbean nation the Republic of Haiti was rocked by a 7.0 magnitude earthquake. It resulted in an estimated 250 000 fatalities and focused much of the world&#8217;s media on the small island nation. A little over a month later, Chile was struck by a huge 8.8 magnitude earthquake, at first giving rise to fears of a tsunami in the Pacific, but later downplayed. The quake resulted in a reported 250 or more deaths. Indeed, every month this year has seen at least one earthquake in the region of magnitude 7.0. The increased media attention has prompted people to ponder the question: why have there been so many earthquakes recently? </p>
<p>One reason for the apparent increase is in our increased use of technology to detect and record earthquakes. Both the United States and Europe now have sophisticated global stations in place to record even the faintest of earth tremors. The European-Mediterranean Seismological Centre detected 52 earthquakes in the vicinity of the Mediterranean Sea on 17th June 2010. Likewise, the National Earthquake Information Centre, a part of the US Geological Survey, now detects between 12 000 and 14 000 earthquakes annually. So clearly, our ability to detect earthquakes has increased many fold.  </p>
<p>Similarly, the sheer number of detecting stations has increased dramatically. In 1931, there were around 350 station worldwide; today, there are in excess of 4000 stations. The US Geological Survey indicates that there have been, in fact, fewer high magnitude earthquakes than expected in recent years. In any given year, long-term measurements suggest an average of 18 major (magnitude 7.0 to 7.9) earthquakes and one great (magnitude 8.0 or higher) quake. Few years in the last 25 have exceeded this expected figure, and in no year in the 21st century has this average figure been met; only in 1992, 1995, 1996 and 1997 was this figure reached or exceeded. </p>
<p>Another reason for the apparent increase in quakes may be that increasing global populations put more people in known quake regions. Greater populations in quake zones leads to greater human cost, which, in turn, assures greater media coverage. At the time of writing, the devastating Haiti quake is only the equal sixth largest quake by magnitude for the year 2010. The other five, of respective magnitudes of 8.8, 7.8, 7.7, 7.2 and 7.1, resulted in far fewer, and in most cases no, reported fatalities and consequently did not make the front pages of the newspapers or new web sites – most probably went unnoticed by all bar those directly involved. </p>
<p>Statistical analysis indicates that earthquakes generally occur in clusters. Again, when clusters occur they are often reported in the media and gain widespread attention. Similarly, sequences of small events, often causally linked, are common in some places, particularly geothermal regions; also, larger quakes can often trigger secondary quakes. When the opposite occurs, and we experience a period of reduced global seismic activity, are we all to sit back and ponder: hey, why no catastrophic earthquakes lately?</p>

			<content:encoded><![CDATA[<p>The Kardashians are an Armenian American family, based in Los Angeles, California. Although the younger members of the family are now household names in the United States, it was the late father, attorney Robert Kardashian, who first appeared regularly on our television screens owing to his long friendship with disgraced football ace O. J. Simpson. </p>
<p>Robert Kardashian was a friend of Simpson&#8217;s since the 1970s and stood by Simpson throughout his high profile murder trial. Although Kardashian let his license to practice lapse prior to the Simpson murder case in the mid-90s, he re-enabled it to work as a voluntary member of Simpson&#8217;s legal team, and was often seen sitting by Simpson&#8217;s side during court proceedings. Kardashian also, notably, read a letter to waiting media following when Simpson failed to turn himself in, in 1994.<br />
The tremors emanating from the high profile court case continued in the media but eventually petered out. Robert Kardashian passed away in 2003, aged 59, following a battle against oesophageal cancer. </p>
<p>Following an amicable split in 1991, Kardashian&#8217;s former wife, Kris Houghton, married former Olympic decathlete Bruce Jenner. By 2007, the Kardashian offspring were busy establishing their media careers. It was eldest daughter and long-time friend of socialite Paris Hilton, Kim, who next came to the attention of the world&#8217;s media. In 2007, a tape showing her having sex with California-based rap star Ray J first appeared on the Internet. The ensuing melee between Kardashian and the porn-house Vivid Entertainment over the ownership of the tape assured much media and Internet exposure. Eventually, it is said, Kardashian agreed to settle out of court for a sum of around $5 million.<br />
Later that year, on 14th October, American TV station E! premièred “Keeping Up with the Kardashians”, a reality TV series following the lives of the Kardashian-Jenner family. The first season featured 8 Sunday night shows and reportedly raked in 13 million viewers within its first month on air. The show documents the lives of the Kardashian-Jenner family as they deal with the ups and downs of daily living, along with numerous scares and surprises. Following the success of the opening season, E! Aired the 10-show season two in 2008, season three in the spring of 2009 and season four between November 2008 and February 2010. </p>
<p>In addition to Keeping Up with the Kardashians, Kim has put her intrinsic talents to good use in other areas. She posed nude for the December 2007 issue of Playboy magazine, and clinched several modelling deals, notably for Bongo Jeans. In 2008, she continued her acting career in Disaster Movie and later appeared in long-running television series, How I Met Your Mother. She also appeared in the 2008 ABC reality show Dancing With the Stars, finishing a commendable 11th.  In 2009, Kim made a guest appearance in the popular crime show CSI:NY. </p>
<p>Like her sisters, Kim is also involved in numerous other ventures, including a workout video and a perfume named Kim Kardashian. The Kardashian sisters are co-owners of D-A-S-H boutique in Calabasas, California.</p>
