Paintball is a safe, simple yet challenging and strategic sport that is played usually by two teams, each with at least two players. Adults and kids alike enjoy this sport as they often refer to it as an advanced or improvised game of tag.
Tournaments attract many spectators of all ages, as it is a very exciting game to watch.
Paintball games are of various types, however, the most popular game often played is called "capture the flag". The object or the goal of this game is for teams to advance to the opponent’s base, move the other team’s flag to its destined location, at the same time guarding your own flag.
The paintball field has many obstacles such as tires, forts, old cars, hay and the newest are “inflatables” that are constructed as a refuge for team players; making the game all the more exciting, as if participating in an actual game of war in videos.
When one is hit, it can hurt briefly and at times give players bruises. Players are typically required to be in long sleeves shirt and pants, making sure that the colour is not identical as that of the judge and complete paintball gear such as mask, helmet and goggles for safety.
The sport of paintball has a distinct and accurate set of rules that are strictly followed. The producer of the tournament is the absolute authority in regard to either an alteration or addition to the rules; marshals oversee the event, and their decision is always final. No dispute on the paintball field is accommodated or entertained.
A military approach to paintball is useless, as that knowledge is recognized and understood by the teams. A team’s tactic should be carefully planned; your team’s line of attack will not be known by the opposing team, and there should be a quick switch of plans in case something goes wrong.
There must be a lot of teamwork involved, as everyone moves through the field. As a team member moves, there should be others to guard and keep watch and give off covering shots when necessary. A team that moves together with a common objective will have a great chance of succeeding in this game.
Communication in the field is also very important. A team-mate can shout the position of the opponent. The moment that a player is seen, the game for that player is up; so there is no reason for you to keep quiet; instead, inform the others the location of the enemy.
The excitement of this game concludes when you are seen and eliminated - a situation that all team players struggle to avoid.
Autopilots The first self-steering gear was introduced in the 1920s to control model yachts but it was not until 1948 that the principle was applied to full-scale yachts. Standing at the helm for lengthy periods, monitoring instruments and keeping a good lookout can be very tiring. An autopilot relieves the helmsman from steering the correct course leaving him free to maintain a proper watch. The autopilot can be set to either steer a compass course or a course relative to the wind. A fluxgate compass or electronic wind indicator feeds information to a microprocessor which then makes the necessary rudder movements to return the vessel to it's required course. The mechanical power is applied to the rudder by either electric linear activators, hydraulic pumps or rotary drives. GPS/Chart
plotters can be used to input navigational instructions to the autopilot.
Battery Chargers will keep batteries fully charged thereby extending their working life.
Chart Plotters Typically a chart plotter consists of an antenna, mounted high on the boat, to track GPS signals and a display unit sited either at the at the navigation station or the helm of the vessel. The vessels position is sent from the antenna to the display unit which in turn shows it graphically on the chart. The Chart itself will look similar to its paper equivalent and show depth, land mass, navigational aids such as buoys and potential dangers in the form of wrecks and obstructions. The user can add waypoints to the chart and zoom in and out of the display. Chart plotters can be connected to drive an autopilot and/or send GPS data to a fish finder or radar. They can also interface with a laptop enabling complex passage planning to be done away from the boat and then entered into the chart plotter after arriving at the boat.
Magnetic Transmitting Compasses work like traditional compasses using magnets to determine the vessels orientation to the earth's magnetic field they then transmit the boats heading to an electronic display. They make steering easier than with conventional compasses because they display steadier headings and do not suffer from the "lag" that occurs when making a turn. They can interface with chart plotters, autopilots and radar. Fluxgate Compasses consist of two pieces of readily saturated magnetic material with coils wound around them in opposing directions. AC current is passed through the coils and the material is saturated in one direction and then the other. The earth's magnetic field affects slightly the time at which saturation occurs, earlier in one coil and later in the other. The difference is then calculated giving an output proportional to the earth's magnetic field. They are accurate to 0.1 of a degree. Their output can be displayed digitally to the helmsman or they can interface with autopilots, chart plotters and radar.
Echo Sounders work on the same principle as sonar. A transducer emits a narrow beam of high-frequency sound. This is reflected by any solid objects and the time between transmission and receipt of the echo is measured. The speed of sound through water is known and so the range or distance to the seabed can be calculated. That is then displayed in meters. Forward-Looking Sonar (FLS) enables you to see the underwater hazards before you're actually on top of them. A typical range for an FLS is 150 meters.
An Emergency Position Indicating Radio Beacon (EPIRB) is a piece of equipment designed to float free of a vessel in distress. It then sends a radio signal that can be detected by Search and Rescue Satellite Aided Tracking (SARSAT) satellites. They relay a message to a ground station that in turn can instigate a search and rescue operation.
Fish Finders use the same technology as sonar. A narrow beam of high-frequency sound is transmitted by a transducer, this is reflected by solid objects such as the seabed. By developing this technology fishfinders provide displays that show where the fish are and they can differentiate between baitfish and larger species
Global Positioning System (GPS Receivers) - This system was originally designed for military purposes and is owned and operated by the United States Department of Defence. 24 satellites are arranged in a "birdcage" around the globe, they are positioned in such a way that at any place on the earth's surface a direct line of sight can be established to a minimum of 4 satellites. A fix is obtained by measuring accurately the distance between a satellite and the GPS receiver at a precise time. Because the exact position of the satellite is known, these distances provide position lines which are converted by a microprocessor within the GPS receiver to readouts of latitude and longitude.
The log is used to measure the boats speed through the water. A paddle wheel or impeller, mounted below the waterline is turned by the flow of water, this generates electrical impulses that are fed to a microprocessor that displays both speed and distance run.
Inverters - On most boats today you will find domestic equipment of one sort or another. For onboard entertainment, there are televisions and stereo systems. With the popularity of chart plotters comes the PC or laptop. Maintenance often requires the use of power tools. Liveaboards might have a washing machine, dishwasher or microwave. Can take 12v, 24v or 48v supply and convert it to a stable 110 v or 220v AC supply.
Navtex can perhaps best be described as a continuously updated telex service providing navigation and weather information within specified areas. An onboard receiver, tuned to 518kHz, the worldwide Navtex frequency, if left turned on will either print out or display the latest messages sent from a local station. The service is available up to 400 miles from the coast.
Radar enables you to see what otherwise would be invisible. They offer the greatest benefit at night and in fog or rain and are of particular value when close to shore or in busy shipping lanes. They consist of an antenna and a display. The antenna sends out a stream of RF energy which is reflected back off hard objects. When this energy is bounced back it is converted to a signal which displayed to the user. The antenna rotates every few seconds, the display continuously calculates the direction of the antenna and so a precise bearing to the target is calculated. The time is measured for the energy to be reflected and so the distance of the target is also displayed.
Satellite Phones consist of an antenna, a modem and a normal handset. They are powered by an iridium battery. Their range is anywhere covered by in Inmarsat Mini-M satellite. Voice, fax, email and data can be transmitted.
Satellite TV requires an antenna and of course a television. Reception is available within a "footprint" which is based on EIRP (Effective Isotropic Radiated Power) of a transmitting satellite. The EUTELSAT together with the two ASTRA satellites covers Europe. NILESAT and the two ARABSATs cover Africa and the Middle East. Good coverage is also available in North, Central and Southern America.
SSB Radio has a range of several thousand miles. You will need an FFC license or the equivalent in whichever country you plan to operate it. Power consumption is a consideration. Up to 100 Watts may be required for transmission. SSB radio requires several items of equipment. A transceiver capable of SSB operation, An antenna, this must be 8 metres long and in practice, most boats use a backstay or shroud for the purpose having fitted the necessary insulators. An antenna tuner matched to the transceiver model. If you want to send an email you will also need and radio modem and computer.
VHF Radio The power required to transmit is minimal, all sets have the option of transmitting on either 1 Watt or 25 Watts and the lower power should be used whenever possible. Unlike telephones that allow you to both talks and hear at the same time, most VHF sets require you to press a transmit button prior to talking. This is known as simplex. Duplex sets are available but are much more expensive. VHF radio waves travel in straight lines so the aerial should be mounted as high as possible, preferably at the masthead.
For centuries astronomers have speculated about the famous Star of Bethlehem, which the three Magi (the three wise men/the three kings) followed to the place of Christ's birth. Of course, the star may defy scientific explanation altogether, and be viewed as a miracle. Nevertheless, various astronomical theories have been proposed, including that the star may have been a comet, or a supernova (an exploding star), or a "planetary conjunction" (a gathering of planets in one part of the sky). In this column, we'll examine two of today's most popular theories, both of which hold that the planet Jupiter played a key role.
First, though, it's useful to recall what the Bible says about the most famous star in history:
"After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem and asked, "Where is the one who has been born king of the Jews? We saw his star when it rose and have come to worship him." When King Herod heard this he was disturbed, and all Jerusalem with him. When he had called together all the people's chief priests and teachers of the law, he asked them where the Messiah was to be born. "In Bethlehem in Judea," they replied, "for this is what the prophet has written: "'But you, Bethlehem, in the land of Judah, are by no means least among the rulers of Judah; for out of you will come to a ruler who will shepherd my people Israel."
Then Herod called the Magi secretly and found out from them the exact time the star had appeared. He sent them to Bethlehem and said, "Go and search carefully for the child. As soon as you find him, report to me, so that I too may go and worship him." After they had heard the king, they went on their way, and the star they had seen when it rose went ahead of them until it stopped over the place where the child was. When they saw the star, they were overjoyed. On coming to the house, they saw the child with his mother Mary, and they bowed down and worshipped him. Then they opened their treasures and presented him with gifts of gold, frankincense and myrrh. And having been warned in a dream not to go back to Herod, they returned to their country by another route." Matthew 2:1-12
If you Google "Star of Bethlehem," the Web site of a best selling DVD, The Star of Bethlehem, ranks at the very top. The DVD features American attorney, Sunday school teacher, and amateur astronomer Rick Larson, who has conducted extensive research into the scientific, historical and theological aspects of the Star of Bethlehem.
After a careful review of scripture, Larson identifies nine characteristics of the star that, he believes, any scientific theory of the star must meet in order to be compliant with Christian belief. For example, we can see from Matthew 2:1-12 that the star signified the birth of a king, that it was associated with the Jewish nation, and that, "it stopped over the place where the child was" - Bethlehem.
Larson then draws on his study of ancient history to address the all-important issue of the year that King Herod died. According to Matthew 2, after the birth of Jesus, an angel appeared to Joseph in a dream, urging Joseph to flee Israel and take Mary and the infant Jesus to Egypt so as to avoid the wrath of Herod, who had issued orders that all male children in his realm under the age of two be executed. Later in Matthew 2, an angel informs Joseph that Herod has died and that it is safe to return to Israel. So the argument goes that we should subtract two years from the year of Herod's death to estimate the year Jesus was born. Knowing Jesus' estimated year of birth allows astronomers to run computer simulations of the positions of the stars and planets as they appeared in the night sky during the approximate time frame of Jesus' birth.
Most historians and biblical scholars put Herod's death at around the year 4 BC, meaning Jesus would have been born sometime around 6 BC. But Larson points to recent historical research arguing that Herod died in 1 BC, which would place Jesus' birth year around 3 BC.
Using modern astronomical software, Larson then runs computer simulations of the night sky over the Middle East in 3 and 2 BC and reaches two remarkable results - both involving the planet Jupiter.
Viewing the night sky from Jerusalem in mid-September of 3 BC, an observer could see Jupiter, known as the "King Planet" (from classical mythology) in conjunction with (i.e., close to) the star "Regulus," known as the "King Star. Furthermore, Regulus is in the constellation (area of the night sky) "Leo," which represents a lion, which was the symbol of Judah.
Furthermore, Larson notes, the planets in the night sky move relative to the 'fixed' stars: If you note the position of, say, Jupiter relative to stars such as Regulus from night to night, then you'll note that Jupiter generally moves eastward across successive night skies. However, occasionally, Jupiter will seemingly halt its eastward movement, and begin moving westward across successive night skies. (This is an optical effect - called "retrograde motion" - resulting from the fact that Earth's orbit around the sun lies within Jupiter's orbit around the sun. Jupiter, Saturn and other planets outside Earth's orbit demonstrate the same retrograde motion as we view those planets from Earth, which itself is in motion in its orbit about the sun. Our planet's orbital motion combined with the orbital motions of the outer planets cause the retrograde motion optical effect.) As Jupiter switches from moving eastward to moving westward (or vice versa), Jupiter appears to be stationary relative to the stars. In this way, Jupiter appeared to stop "over the place where the child was," as we read in Matthew 2.
But, Larson argues, this conjunction of Leo with Regulus may have marked the conception of Jesus. If we run the computer simulation of Jerusalem's night sky forward nine months into June of 2 BC, we find that Jupiter and the planet Venus - two of the brightest planets in the night sky - come into extremely close conjunction, so much so that the two planets appear together as one, very bright 'star' in the night sky!
So the conjunction of Jupiter with Regulus in 3 BC, and/or the conjunction of Jupiter with Venus nine months later in 2 BC, may very well have been the star the Magi followed.
If we return to the Google search results for "Star of Bethlehem," we find the Web site of professional astronomer Michael Molnar, who takes a different approach to the star of Bethlehem. In his book, The Star of Bethlehem: The Legacy of the Magi, Molnar explores not only the Biblical account of the star but also the point of view of the Magi, whom Molnar argues were astrologers/astronomers: In the ancient Roman world, astrology and astronomy were indistinguishable. The Magi were held in high esteem in Roman culture and were considered to be very knowledgeable, indeed, wise men.
Molnar, who does not believe in astrology, nevertheless has extensively researched the astrological beliefs prevalent in the Roman world. He argues that modern astronomers who think about the Star of Bethlehem make a mistake by focusing on what spectacular displays may have appeared in the night sky around the time of Jesus' birth, such as the appearance of a very bright star. The focus on amazing heavenly displays is a bias of relatively modern astronomers, Molnar argues. The Magi of ancient Rome, Molnar explains, were primarily concerned with the logic of their astrological system, which placed primary emphasis on the locations and arrangements of the planets in the night sky - the sequence of planets in the night sky, what constellations they were in, how far above the horizon they appeared at sunrise, etc.
So, for example, the fact that Jupiter and Venus were so close to one another that they appeared as one, very bright star would not necessarily be significant to the Magi. Rather, the Magi would be much more interested in knowing whether Jupiter was to the east of Venus or to the west of Venus, the constellation(s) in which the two planets were located, and how high above the horizon the two planets appeared at sunrise.
Accepting the consensus view of most scholars that Herod likely died in 4 BC, Molnar considers the positions of the planets in the night sky two years earlier - in 6 BC - and finds a particular arrangement of the planets Jupiter, Saturn, Venus, Mars and Mercury, together with the Moon and Sun, that would have been of great astrological significance to the Magi, indicating that a king was being born. Furthermore, the centring of this particular planetary arrangement in and around the constellation Aries was significant, in part because in Roman-era astrology Aries was the sign of Judea. So to the Magi, the arrangement of the stars and planets in 6 BC led them to believe that a great king was born in Judea. Moreover, we should bear in mind Jupiter's retrograde motion, as well as the spirit of revolution in the air at the time - the notion that a messiah would soon lead the Jewish people in revolt against the Roman Empire. All of these factors combined, then, would naturally have induced the Magi to travel to Jerusalem - the capitol city of Judea - to inquire as to the whereabouts of the newborn king.
So whether we take the more Biblically-oriented analysis of Larson or the more astrologically-oriented analysis of Molnar, we find compelling scenarios that support the notion that the Star of Bethlehem was a real, historical event.

The brain is a fascinating and complex unit of our anatomy. The brain is responsible for so many things. It stores our short term and long term memories. The ability to learn is from our brain as well. Our emotions and triggers are stored in our brain. The brain is a source of information on everything we do and about who we are.
The anatomy of the brain shows us just how complex it truly is. There is so much about brain science and the medical field have not yet uncovered. However, there is a great deal we have learned about the brain by studying the physical features of it. We have also learned from the neurological aspects of the brain. We have the ability to perform brain surgery and remove tumours as well as install plates for those who have neurological damage. This is a fascinating area of science and medicine that can be overwhelming to learn about in detail.
There are six main areas of the brain to learn about. The parietal lobe helps us understand written language as well as communicate with others. Our sensory cortex is located here, controlling the sensations we get with touching and amounts of pressure. This is also an area of judgment for size, weight and distance.
The occipital lobe is located at the rear of the brain. This is where visual information is processed. It helps users to recognize shapes and colours. The cerebellum helps us with coordination including balance and muscle movement that help you walk, talk, eat, and routine tasks involved in caring for ourselves.
The brainstem is a very important part of the brain. It is connected to the spinal cord. This portion of the brain helps with required body functions including breathing, digesting, the regulation of the heart rate, blood pressure and being alert while awake.
The temporal lobe is how we smell. This is surprising information for most of us who think only the nose is responsible for our sense of smell. This region is also used for short-term memory processing.
The frontal lobe is a very important portion of the brain. It is responsible for planning, organizing, problem-solving, paying attention to details, behaviour, and emotions. This is the area of our brain we use the most in our daily routines and decisions.
Since the brain performs so many features, it is obvious why a brain injury can be so serious. It can result in death if areas such as the brainstem are affected. Brain injuries can affect how other areas of the body are able to function. Ironically, we only use about 10% of our brain!
Okanagan is a mountain range that runs through valleys close to three mountain ranges. During the summer this is the perfect place to do some camping, but when winter hits you will have great skiing weather and conditions. There are small resorts that are scattered throughout the area. The climate here will make for great skiing down the slopes and through the trails.
These scattered resorts are very quiet and peaceful. Lifts are available, but they are limited to specific times and dates. These resorts have great skiing around them, even though they are small. This area of mountains offers the most consistent weather conditions, and the resort offers to lodge for everyone that cares to stay - at a reasonable price.
The mountain ranges offer different trails and skill levels, but most of all they provide you with the skiing vacation of your dreams. During the winter, temperatures in the Okanogan range often drop to zero degrees. The items you bring will need to keep you warm at all times and safe no matter which trail you may choose to ski.
When you buy a radio-controlled plane for the first time, you may have some difficulty choosing the plane that will introduce you to the remote-controlled hobby. You will want something that will be fairly cheap to purchase and will give you a chance to learn how to fly remote-controlled planes before you move onto more advanced planes. If you buy the first plane that you see, you could end up having a very bad experience for your first time, and be completely turned away from the hobby. This is why it is very important to know that there are many different characteristics that you can look for. In this article, I will go over most of them. So read on to find out about what you need to look for to have the best experience possible when you fly a radio-controlled plane for the first time.
First, you need to assess your own building skills. You can buy airplane kits that require you to build the entire thing from scraps of wood, or you can buy kits that just require you to snap a few parts together. If you want to make a huge, prolonged project out of your radio controlled plane, then you can buy one that requires full assembly. However, you should always be sure that your building skills are up for it. If you don’t want to spend the time required to do this, or if you don’t have the prowess to build it, then you can buy a plane that does not require any assembly at all. You just pull it out of the box, and you’re ready to go flying for the afternoon.
Next, you will want to look for something that has stability for people without are flying for the first time. It may not seem like it, but to fly a radio-controlled plane you need at least some skill. But, if you search for the right item you can find something that is more geared towards beginners. Slow flying speed is always a benefit, just as driving slow is a good way to learn how to control a car for the first time. You will want a light plane with larger wings that can catch the wind better. This will make takeoff easier. You will also want to look for planes that have flat bottoms, and wings mounted high on the body. If you get a plane that has all of these features, your maiden flight will be as smooth as possible.
Next, you need to consider the model of the airplane you are going to buy. You can get model replicas of almost any type of plane, from the first Wright Brothers’ plane to modern military jets. If you are buying a model plane, you are probably already interested in planes, to begin with. Think of what plane you are most intrigued by when you look through plane books and see if you can find a kit that is modeled after that plane. This will give you a personal interest in the model that you are getting. When you fly it for the first time, it will be almost like being in the cockpit of the actual plane.
After you have decided on these issues when picking your plane, the rest is just up to personal preference. But if you pay close attention to these and pick your plane carefully, you will find that radio controlled flying is a great way to spend your time. It is a very rewarding hobby, and it can last you a lifetime if you choose planes that are compliant with your level of skill. After all, you don’t want to go out on your first flight and then crash your plane directly into the ground or a tree. So choose your first plane carefully, and you can avoid being immensely frustrated in the future.
New York City offers a virtual treasure chest of fun things to do for teenagers. This age group is generally the most difficult to please and appease while vacationing. They are too old for the kid stuff and too young to appreciate some of the more 'grown-up' entertainment and of course, they don't want to look like they're having too much fun. From amusement parks to cyber cafes, from bookstores to malls and video arcades, to sporting events and sporting complexes New York City is a city that was almost made for teens to enjoy.
The trick to enjoying your New York City vacation while ensuring that your teen enjoys his or her time in the city is compromised. Agree to go watch the skateboarding in the park if he or she will suffer through a museum with you. You just might find that you each find something to enjoy about the other's activities. There are so many wonderful things to do and see in New York. You don't have to pay a lot of money in order to have a good time as many of these wonderful events are offered free or for very little cost. You can also purchase passes that allow free entrance to certain city attractions for one low fee. You will find that of the freebie offerings there is usually something that will appeal to various members of your family including your teens.
Compromise is a good idea on any vacation with friends or family and it teaches your teens an important lesson-their opinion matters to you. They also learn to compromise, to share time and experiences, and to think critically. They are forced to weight all the things they would like to do and select the things that matter most to them to do. This is a very good thing for people to learn as early as possible and will be an invaluable lesson, as they grow older and eventually begin making their own decisions in life as well. I even try to offer the younger children a voice in what's going on. I offer age-appropriate choices and allow them to select the one that matters most to them.
Teens are often very hard to please or predict and their wants can change between the time it takes to open a pack of pop tarts and the time it takes to actually drop them in the toaster. Be aware of this when making plans with teens and go with the flow. You do not have to let your teen rule your vacation but by allowing him or her a voice in the decision-making process you might all learn some important and interesting things about each other.
Girl teens are often easily distracted by shopping-while New York City has some of the trendiest boutiques you may want to see if you can talk her into some of them any consignment or secondhand stores that abound. You can call it 'vintage clothing' if you must in order to get her in the doors but you can score some awesome deals on clothes that look barely worn if that and she'll have some nice additions to her wardrobe for a fraction of their costs if new. There are also some wonderful outlet malls in NYC as well. The trick with shopping any of these stores is to know the prices of things. Some things are excellent bargains while others are not so much.
Teen boys will have a grand time at places such as Game Time Nation where they can play video games for endless hours. You can even try playing games together if you're brave enough. Fair warning offered here, teens are brutal in their victories and you will never live down your failures in the video game arena with them so study up beforehand.
The most important thing to remember about vacationing with your teen is that you'd like them to have some fond memories of your time together, even during their teen years. Take care that you are including them in your plans rather than making their plans for them. It is time they are let into the decision making process to some degree even if it's allowing either or options or asking them to list a few things they'd like to do and you selecting from those. If you're having fun it is quite likely that they will eventually join in.48
It is thought, by some, that the foundation American Quarter Horse stock has at its roots Arabian, Turk, and Barb breeds. Others believe that the breed began with the acquisition of Chickasaw horses which were likely of Spanish extraction. Their history seems to begin around 1690, when horses exported from England were bred with native horses in America. The result of this cross was a small, stocky horse which was extremely fast in the quarter-mile sprint which the colonists loved to participate in during their off-time. Even when pitted against Thoroughbreds, this little horse came in first more often than not. Thus, the horse became known as the Quarter Horse.
In the 1800s, when the pioneers began to move west, they wanted a horse that could endure the rigors and was always willing to work. Their horse of choice was the Quarter Horse. They quickly found that the breed was excellent to use when working with cattle. Cattlemen soon preferred this animal because it seemed to know ahead of time what the cattle would do, and naturally moved to direct the herd where the cowboys wanted them to go. Even after the automobile was invented, Quarter Horses were still used almost exclusively on many ranches.
In 1940, the American Quarter Horse Association (AQHA) was formed. From that year until the present, Quarter Horse breeders have worked diligently to perfect the bloodlines. The Association has set forth strict guidelines with regard to registration of American Quarter Horses. AQHs are allowed to have limited white markings on their faces and below their knees. If there are white patches or spots anywhere else on the horse, it is considered to not be a true Quarter Horse.
The AQHA recognizes 13 colors as acceptable for the breed. The most dominant color is sorrel, which is a reddish-brown. The other colors are bay, black, brown, buckskin, dun, gray, grullo, palomino, red roan, and blue roan. What is called a gray is what most of us perceive as white. But, there are no "white" Quarter Horses.
There are two main body types which are acceptable for registration as Quarter Horses. The "stock" type, which is shorter, more compact, stockier, and well-muscled, yet agile. The "running" type is lighter and is bred and trained for sprinting.
Because this breed is very versatile, bloodlines are built with specific tasks in mind when producing the offspring. For AQH's shown "at halter", the line is bred to have a heavier body appearance, because these horses are incredibly muscled. For horses used as "reiners" and "cutters", the build is usually smaller and the horses possess cat-like quicker movement and powerful hindquarters. Those bred for Western pleasure riding have a level "topline" and smoother gaits. Those which will be used for racing have longer legs and a leaner body build and those bred as show hunters have a similar build to the runners, but their bloodlines will include traits which are suited to horses used for hunting purposes. The whole Quarter Horse breed possesses speed, stamina, power, and an inherent willingness to please.
This horse is usually 14 to 16 hands (56 to 64 inches, or 142.24 to 162.56 centimeters) at the shoulder. The weight can vary drastically, depending on the purpose for which the horse was bred.
The American Quarter Horse is the most popular breed in the United States. And there are approximately 3.7 million registered American Quarter Horses worldwide, making it one of the most populous breeds in modern history.
Dauphin Island, Alabama is a barrier island at the Mouth of Mobile Bay. It is a tourist attraction, the home of around 1,200 people, the site of the Estuarium marine sciences laboratory and a164-acre Audubon Bird Sanctuary. It’s a pleasant, pretty and useful place that receives most of its income from tourism. On the face of it, one could hardly guess that Dauphin Island bore the name “Massacre Island” for 8 years, or that it was occupied by every major European power in American history at one time or another.
The earliest records of human activity on Dauphin Island are the burial sites of the Native Americans known as the Mound Builders. The Serpentine shell middens on Dauphin’s northern shore suggest that this culture had been using the island for 1,000 years before the 1st Europeans arrived in the Americas, possibly occupying it on a seasonal basis, and definitely using it as sacred ground for the honored dead.
Spain got the jump on the rest of the Old World when it came to America’s. Since we attribute the continents “discovery” to that country (even if Columbus is to be taken at his word that he was, in fact, Italian) it is only fitting that Spanish explorer Alonzo Pineda was the 1st European to map the Dauphin Island in 1519. By standards of the time, his work is considered incredibly detailed and accurate.
It wasn’t until 80 years after Pineda made his map that the next great European colonial power arrived on Dauphin’s shores. In 1699 French explorer Pierre Le Moyne, sir d’Iberville, future architect of French Louisiana, was beginning his exploration of the mouth of the Mississippi. He and his men anchored on Dauphin Island and, in a textbook European misreading of Native American culture, mistook the human remains he found there as the aftermath of some savage (or savages’) battle or atrocity. Thus the Island received the name “Massacre Island”.
Bones or no bones, d’Iberville liked what he saw. Under the French Massacre Island became a settlement, trading-post and, for a time, the capitol of the Louisiana Territory, a.k.a. 2/3rd’s of the continental United States. As such, “Massacre Island” began to seem an inappropriate name. In 1707 the island was renamed Dauphin Island in honor of the “Dauphin” of France, the title given to the prince who is the heir to the French throne.
Later events would suggest “Massacre Island” was a more appropriate name after all. In 1711 pirates raided Dauphin Island, with all the attendant murder, rape and pillage one might expect. In 1717 a massive Hurricane very nearly leveled every structure on the island. Then, horror of horrors, the British arrived.
For the better part of 100 years, Dauphin Island was a microcosm of colonial European conflict in the Gulf of Mexico. Great Britain took it from France. Spain took it back from Great Britain. Virtually the only players on the North American field who didn’t reclaim it was the Indians. Back and forth it went until 1813 when a still green United States acquired the entirety of Mobile Bay, Dauphin included. The British took the Island one last time, for old times sake, during the War of 1812 (or actually a few months after; communications were very slow in the early 19th century), but after that Dauphin Island has remained thoroughly Alabaman until the present.
Dauphin has seen a great deal of American history unfold, from cultures of the 1st immigrants who came via the Bering Strait, to the earliest efforts of the conquistadors, to the western European scrum over valuable New World real estate. All in all, that’s not too shabby for a little strip of land off the edge of Alabama.
The snowmobiling industry has enjoyed a rich history that has made it possible to travel easily through the thick snow that often falls in Canada and the northern regions of the United States. For decades, snowmobiles have continually improved to meet the needs of residents who enjoy living in the colder climates and experiencing the winter months to their full potential. As with any major invention, however, the snowmobile industry was popularized by high-performance models and sports enthusiasts who have found ways to race the machines and compete against other snowmobilers in a variety of events. This industry has come a long way since the early purpose of the snowmobile as being merely a means of traveling through the snow with less difficulty.
The first patent for the snowmobile was issued in 1927 to Carl J. Eliason of Sayner, WI. His idea of a machine that traveled easily through the snow was simply called a “snow machine.” He used parts from a bicycle, a pair of skis, and some parts from an old Model-T Ford to create his first machine. It was a functional contraption, but it had its drawbacks and disadvantages. Eliason’s “snow machine” was more or less a great concept that was not perfected in a way to reach the full potential of the idea.
It was not until 1958 when Joseph-Armand Bombardier of Canada created and patented the machine that we know today as a snowmobile. Not only did Bombardier create and manufacture the first modern-day snowmobile, but he was also the first person to successfully market the machines to people throughout North America. His most popular model – the B7 Snowmobile – began being mass produced for sale in North America before introducing the more popular Ski-Doo model. The Ski-Doo was a more popular model of snowmobile because it was smaller and less expensive. Soon, the Ski-Doo replaced dog teams as a means to quickly travel across the snowy landscape.
By the 1970s, less than 20 years after Bombardier received his patent for the first modern-day snowmobile, there were already 250 snowmobile races that were sanctioned across North America. The United States Snowmobile Association became the forerunner in snowmobile organizations. It began and continues to sponsor one of the more popular snowmobile races – a 650-mile marathon that begins in Winnipeg, Canada and ends in Minneapolis, Minnesota. It was also one of the organizations that helped to get the Snocross snowmobiling event added to the Aspen X Games in 1998, which has created the largest increase in popularity for the snowmobile industry.
One of the reasons that snowmobiles have become so popular in North American society is because of their ease of use. Inexperienced users can learn how to ride a snowmobile in a very short time and begin experiencing the fun of speeding across the snowy trails. Many of the resorts in the snowy regions of the United States and Canada, including Utah, Michigan, and Alberta cater to the specific needs of vacationing snowmobilers. Winter vacation resorts commonly keep updated information on snowmobiling trails in the area along with lessons and clubs that snowmobilers of any experience level can take advantage of.
Along with enjoying the fun that snowmobiles can provide is the responsibility of using the machines safely. When snowmobiling along trails or for long distances, it is a good idea to go with another rider and to let others know where you plan on riding to in case of emergency. Always bring extra food along with a first aid kit and the proper safety gear in the event that you get stranded. Before riding, inspect the equipment to make sure all of the parts are properly tightened and in proper working condition. Also, check the dangers of an avalanche occurring before leaving and try to avoid those areas.
The snowmobile industry has made a huge deal of progress in the technology and popularity of the machines. Beginning as merely a means to travel across the snowy lands with less difficulty, the industry has enjoyed a surge of popularity due to the many recent racing events and competitions. Now, snowmobiles are popular among all age groups and they can be thoroughly enjoyed as recreational vehicles when proper safety precautions are followed.
Shatranj is the direct descendant of Chaturanga and had become popular in the Middle East and Persia for almost 1000 years. More so, the modern chess is also
believed to have gradually developed from Shatranj.
The term Shatranj was derived from the Sanskrit Chaturanga, where chatu means four and anga means arm. The game also came to Persia from India during the early centuries of the Christian era. One of the earliest references to chess found in Persia is the book "Karnamak-i Artaxshir-i Papakan", which was written around the 3rd to 7th century.
The game Shatranj adapted much of the rules of Chaturanga, including the basic sixteen piece structure. However, in later variants of the game, the darker squares were eventually engraved. The Shatranj also spread westward and achieved popularity and body of literature on game strategy and tactics from the 8th century and onwards.
The Rules of Shatranj
Initially, the setup of the game is the same as modern chess, although the position of the king of white shah, on the left or right side, was not entirely established. Shatranj is played using pieces, such as:
the king or shah,
the rukh or rook,
the fers or counselor,
the pill or elephant,
the faras or horse
and the baidak or pawns.
Almost all the movements of the Shatranj pieces are similar to modern chess with the exception of the two square movements of the pawn during the first move. There are also other differences of Shatranj compared to modern chess, such as: the castling, which was not allowed but later invented. In the event of stalemating, the opposing king will result in a win.
More so, if a player captures the entire opponent’s pieces apart from the king, that player will normally be declared the winner. However, if the opponent could
capture the last piece on the next move, the game will result in a draw.
The gameplay of Shatranj includes the openings. These were usually called tabbiyya or battle array when translated. However, due to the slow piece progress in the game, the precise sequence of moves was unimportant. Instead, the players aimed to reach a specific position, mostly ignoring the play of their opponent.
Additionally, the pieces used for Shatranj had values, which used a monetary system. Such values include:
one dirhem for the rook,
two-third dirhem for the knight,
one-fourth dirhem for the alfil,
one-third to three-eighth dirhem for the fers,
one-fourth dirhem for the central pawn,
one-sixth to one-fifth dirhem for the alfil’s or knight’s pawn
and one-eighth dirhem for the rook’s pawn.
These values were established and estimated by as-Suli, who was the strongest Shantranj player during the reign of the al-Muktafi caliph, and al-Adli.
Early Beginnings of Shatranj
There are several works written about Shatranj during the Golden Age of Arabic. These recorded the analysis of opening games, knight’s tour, chess problems and
other subjects that are commonly found in modern chess books.
Shatranj players who have the highest class were also called grandees or aliyat. There were only a few players that fell under this category and the most well known are: Abun-Naam, Rabrab, and Jabir al-Kulfi, who were the three aliyat players during the al-Ma’mun caliph rule; Al-Lajlaj who was a great master of Shatranj; and Ar-Razi who won 847 games against powerful Shatranj opponents.
I’ll bet that you have any idea about fly fishing, aren’t you? So, what really is fly fishing? Why bother asking this question? Well, it is relevant to answer the question given that fly fishing has been a matter of public policy. Definitely, this is the most obvious in the implication of certain fishing waters or organisms as clear to the phrase “Fly Fishing Only”. Some can perhaps assume that this is a reasonable current phenomenon. Nevertheless, some waters of the United States have been ignored for “flies only” as recent as 1903.
Probably the Atlantic salmon is the most ancient case of aquatic species being chosen as a prey to be captured with flies only. In the North America region, the existing defacto regulation states that this game fish can be sought only with that is called an “unweighted fly”. This phrase means that the shedding is done by means of fly fishing line as well as leader wherein no extra weight was affixed. This was the definition and the basic idea of fly fishing s suggested by some states such as New Hampshire.
To understand a meaning of fly fishing in a discreet manner you should initially observe what can make fishing with the use of a flying rod, an experience distinct from, for instance, an aid of a lightweight in a weight circling outfit. This article, therefore, suggests the following distinctions:
1.A particular fluid elegance in casting, the fishing rod line unrolling plainly from either a tight or open loop.
2.The efficiency to false-cast, whether to dry the fly line which is fed out or not to make sure of proper placement.
3.A chance of sensitive delivery of a fly and the drift with a little drag.
The prerequisites remarked brought them no ethical and moral requirements. The usage of a flying rod does not assign one on a much higher ground compared to the bait fishermen who exercises usual courtesy to his quarry. All we can complain about fly fishing is the base technical aspects, given that various environments past diverse constraints aside from those mentioned. Nonetheless, if one acknowledges any fact to the first proposition, subsequently, someone running on to a fly from a vessel may not seem to fly fish like the “chuck-n-duck” in fast water is not considered as fly fishing. Finally, acknowledging proposition number 3 would suggest the use of slinkies, lead and some hazardous methods best left cautiously to the circling rod.
It is factual that most states include, during the past 20 years changing their fishing regulations to permit the use of leader as well as on line in “fly fishing only” regions and still refer it as fly fishing. This has been known for the reason that a sudden dramatic change in the character of the “sport” itself.
Several candid longstanding fishermen were also mumbling for the definition loosening comprising those fishermen that had been working fervidly few years prior to the announcement of “Fly Fishing only” places.
Finally, with your own definition, fly fishing is pretty much like the ancient “free verse versus sonnet” cliché. Do you compose a poetry masterpiece within the terms of a certain style for simply the pleasure and elegance it affords, or do decide to work without considerations and strive to convince yourself and other people that it is still pure poetry? Regarding your fly fishing definition, was it sufficient? Well, I suppose so.
Visualize if George Jetson had his own microbrewery; what would it be like? Would the look be lustrous and space-like? How much superior and rapid could it would it operate? How about the formidable S.S. Enterprise? Can you just comprehend Captain Kirk or Captain Picard enjoying a pint of their own galactic beverage? As well as what would provide power to the machine making such incredible homebrews? Hydrogen cells are creating waves and news as well as the whole lot in between on a planet where shortages of energy are not about economical folklore.
What exactly is a hydrogen cell? What does home brewing have in common with energy conservation anyway? Hydrogen cells are a class of fuel cell, which is, on the whole, an energy conservation device. Fuel cells deliver their own energy, almost always wit the service of a specific source of fuel and an oxidant. Hydrogen acts as the primary source of fuel and oxygen act as the oxidant.
Breweries want engine capacity to manufacture their ales and lagers, and in reality cannot be lacking power at any time. That is where hydrogen fuel cells play an important role; they keep the energy flowing. And being able to "make" energy at home is pretty darn cool. It also helps you being both energy conscious and pretty cost conscious. You might even grace the covers of some magazines.
What can hydrogen cells be used for? Currently, they can be looked at as especially useful support generators of sorts. Scores of companies, including several respected breweries are looking to fuel cells as a means to be extra self-sufficient as far as energy is concerned. This could be excellent news for the future of making beer as a hobby; home breweries running on hydrogen cells. There would be significant reductions in energy usage.
Can hydrogen cells help home breweries? The hope for persons investigating fuel cells is that every individual will be able to exploit most of the advantages that this invention has to offer. You would be able to provide electricity to so much, from your microbrewery to each electrical device in your home by reducing your energy consumption.
There is a general shortage of information on the likely applications of hydrogen fuel cells. Even as some are using fuel cells, the level of what they have got to offer is still being studied. The Sierra Nevada Brewery is using molten carbonate fuel cells and is projecting a reduction of more than $400,000 a year in energy expenditure.
New York City might be a jungle according to many but the animals can be found in its many zoos. If you'd like to check out one or more of the many zoos in New York City I highly recommend purchasing a city pass that will allow you free admission to many of the area zoos. Keep in mind that some of the attractions inside the zoo will cost extra so you should expect to pay something for your day at the zoo(s) but every little bit you can save along the way helps and you will be surprised at how quickly you can recover the cost of your pass.
Bronx Zoo
The Bronx Zoo is the largest urban zoo in the U. S. and is open 365 days a year. Those that have city passes can enjoy free admission to this zoo. Once you've had your fill of the award-winning exhibits the Bronx Zoo has to offer you should check out the New York Botanical Garden, which is located nearby and offers great fun and many activities for children to avoid (this experience is another that can be enjoyed for no additional charge with the New York pass). Also nearby are Wave Hill, the Brooklyn Museum of Art, and Van Cortlandt House Museum. All of these activities are free with the New York pass and are all very much suited for family members of all ages.
Central Park Zoo
The Central Park Zoo offers a view of animals in their natural habitat rather than in cages. While this is becoming more and more of the norm as far as American zoos are concerned the Central Park Zoo was a relative pioneer in this particular process. Today the Central Park Zoo boasts an indoor rainforest; a chilled penguin house along with a pool for the polar bears while also being home to breeding programs for certain endangered species. While you're there be sure to have lunch in the Leaping Frog Café, which offers kid-friendly fare that is surprisingly health oriented (such as trans-fat-free French fries). If you walk through this 6.5-acre zoo wasn't enough exercise for your day be sure to stop by the bike rental area of Central Park, which is located nearby.
New York Aquarium
The New York Aquarium while not exactly a zoo is another great place for the family to experience animal life. This happens to be one of the highlights of many trips to New York. Young and old alike will enjoy watching the marine animals play and frolic while learning important lessons about our marine friends. The aquarium is located at Coney Island and is near Astroland Amusement park if you want to make a day of it. The New York Aquarium offers free admission to holders of the New York Pass and Astroland offers discounts for these holders as well.
Prospect Park Zoo
Prospect Park Zoo offers a unique experience for children to have interactive contact with more animals. This increased interaction makes the trip much more enjoyable for youngsters than many larger zoos which allow little interaction with animals or a very limited number of animals to interact with. The Prospect Park Zoo hosts more than 400 animals representing over 80 species. This zoo is located near the Brooklyn Children's Museum, the Brooklyn Botanic Garden, and the Brooklyn Museum of Art-all of which allow free admission for The New York Pass holders.
Queens Zoo
The Queens Zoo offers a unique experience for visitors in that it is less like a zoo and more like a prairie home for the animals it houses. This 12-acre park is home to 70 animals that live in very authentic habitats. If you choose to visit this particular zoo, be sure that you take the time to visit the barnyard area so that your little ones can feed some of the friendlier creatures. This zoo is located fairly near the Queens Museum of Art, the New York Hall of Science, and the American Museum of the Moving Image. These attractions are all free with the New York Pass.
If you are a true animal lover, then New York City has you covered for opportunities to get your fill. Who would have thought that a city this full of skyscrapers and commerce was also the home to some of the most beautiful and exotic wildlife in the world? (2007)
Achromatic telescope made by Dollond with handle by Hooke - Photo: Wikimedia
In 1733, an Englishman, Chester Moore Hall, created the Achromatic refracting lens. His design limited the color aberrations by using two pieces of glass that were both ground and polished. These lenses usually were employed to see red and blue light. However, the design does not block out all of the rainbow of color around the images.
Achromatic lenses are made from a convex and a concave lens. The concave lens is usually made out of Flint glass, and the convex from Crown glass. They form a weak lens together and can bring two wavelengths of light into a single focus.
Apochromatic refracting lenses are made to view red, green, and blue light wavelengths. The first ones were designed by the German physicist, Abbe.
Some type of fluorite or extra-low dispersion glass is also used and the ending result is a crisp clear image free of the rainbow of color around it. These types of refracting lenses are more expensive than achromatic lenses.
Apochromatic lenses require lenses that can handle three color crossings. They are usually made from expensive fluoro-crown glass, abnormal flint glass, or transparent liquids that are used in the space between the glass. These newer designs allowed for the objects to be free of color around the edges, and they produced way fewer aberrations than achromatic lenses.
Prices on these types of refracting lenses can run high depending on the size aperture you need. Two to three-inch apertures for Achromatic refractors can run between $250 to $1000. Three to five-inch apertures for Apochromatic refractors can run between $2000 to $10,000. Decide which kind you will be using before you buy one. You may just want to look at the night sky or you may want to gaze into the next galaxy.
Chart Plotters Typically a chart plotter consists of an antenna, mounted high on the boat, to track GPS signals and a display unit sited either at the at the navigation station or the helm of the vessel. The vessels position is sent from the antenna to the display unit which in turn shows it graphically on the chart. The Chart itself will look similar to its paper equivalent and show depth, land mass, navigational aids such as buoys and potential dangers in the form of wrecks and obstructions. The user can add waypoints to the chart and zoom in and out of the display. Chart plotters can be connected to drive an autopilot and/or send GPS data to a fish finder or radar. They can also interface with a laptop enabling complex passage planning to be done away from the boat and then entered into the chart plotter after arriving at the boat.
