5 Most Common Maple Varieties in North America

5 Most Common Maple Varieties in North America Acer  sp. is the  genus of trees or shrubs commonly known as the maples. Maples are classified in a family of their own, the Aceraceae, and  there are approximately 125 species worldwide. The word Acer is derived from a Latin word meaning sharp, and the name refers to the characteristic points on the leaf lobes. The maple tree is the national arboreal emblem of Canada.   There are actually twelve native maples found in North America, but only five are commonly seen across most of the continent. The other seven that occur regionally are black maple, mountain maple, striped maple, bigleaf maple, chalk maple, canyon maple, Rocky Mountain  maple, vine maple, and Florida maple. Your chances of seeing a native maple are good in both the urban landscape and in the forest. With few exceptions (Norway and Japanese maples are exotics) you will find these native maples and their cultivars in profusion. Common North American Maple Species Sugar maple  or Acer saccharum.  The star of eastern North American fall foliage viewing and principle source of maple syrup. It normally grows 80 to 110 feet in height, but 150-foot specimens have been known. Compared to other maples, sugar maples color unevenly in the fall; sometimes yellows, oranges, and reds are all seen at the same time.  Red maple  or Acer rubrum. The most widespread maple in eastern North America and ubiquitous  in both the urban and forest landscape. It normally grows to a mature height of about 50 feet. It is a very popular landscape tree but is considered invasive in some forests, where it crowds out native oaks. The upper side of the leaves is green, with the lower side silverish in color. In older trees, the bark is very dark. Fall color is usually a deep red, though some trees may exhibit orange or yellow.  Silver maple  or Acer  saccharinum.  A fast-growing maple used largely as a shade tree, but with problems. This maple is brittle an d subject to breakage. The roots shallow and can cause property damage. At maturity, it may be 80 feet tall. The underside of the leaves is a soft silver in color; fall color is usually a pale yellow.   Boxelder  or Acer negundo  - The most common maple sp. in mid-western North America, and the only maple with pinnately compound leaves. Boxelder has the largest range of all North American maples. It is a fast-growing but short-lived maple, and in favorable conditions, it may grow as much as 80 feet in height. Leaves turn yellow in the fall.  Bigleaf  or Acer macrophyllum.  Restricted to the Pacific Coast, this tree is the most massive of North American maples. It can grow to be 150 feet tall or more, but more typically tops out at 50 to 65 feet in height. In fall, the leaves turn golden yellow.   General Identification Tips The deciduous leaves on all maples are arranged on stems  opposite  each other. The leaves are simple and palmate shaped on most species, with three or five main veins radiating from the leafstalk. The leafstalks are long and often as long a the leaf itself. The boxelder alone has compound leaves, with multiple leaves radiating from the leafstalk.   Maples have small flowers that are not very showy and form in droopy clusters. The fruit is winged key seeds (called  double  samaras) and develops early in the spring. Very visible are the redbuds and new red stems on red maple. Maples have bark that is generally gray but variable in form. Good identifiers of maples in dormancy are: Crescent-shaped leaf scars with three bundle scarsA terminal bud that is egg-shaped and slightly larger than the lateral buds on the branchStipule scars are absent  Opposite leaf and twigs

Hipparchus the Astronomer, Geographer, Mathematician

Hipparchus the Astronomer, Geographer, Mathematician If youve studied math at a high school level, you probably have experience with trigonometry. Its a fascinating branch of mathematics, and it all came about through the genius of Hipparchus of Rhodes. Hipparchus was a Greek scholar considered the greatest astronomical observer in early human history. He made many advances in geography and mathematics, specifically in trigonometry, which he used to construct models to predict solar eclipses. Because math is  the language of science, his contributions are particularly important.   Early Life Hipparchus was born around 190 BCE in Nicaea, Bithynia (now known as now Iznik, Turkey). His early life is mostly a mystery, but what we do know about him comes from Ptolemys Almagest. He  is mentioned in other writings as well. Strabo, a Greek geographer and historian who lived around 64 BCE to 24 AD called Hipparchus one of the famous men of Bithynia. His image, usually depicted sitting and looking at a globe, has been found on many coins minted between 138 AD and 253 AD. In ancient terms, thats a pretty important acknowledgment of importance. Hipparchus apparently traveled and wrote extensively. There are records of observations he made in his native Bithynia as well as from the  island of Rhodes and the Egyptian city of Alexandria. The only example of his writing that  still exists is his Commentary on Aratus and Eudoxus. Its  not one of his major writings, but its still important because it gives us an insight into his work. Life Achievements Hipparchuss major love was mathematics and he pioneered a number of ideas we take for granted today: the division of a circle into 360 degrees and the creation of one of the first trigonometric tables for solving triangles. In fact, he very likely invented the precepts of trigonometry. As an astronomer, Hipparchus was curious about using his knowledge of the Sun and stars to calculate important values. For example, he derived the length of the year to within 6.5 minutes. He also discovered the precession of the equinoxes, with a value of 46 degrees, which is fairly close to our modern number of 50.26 degrees. Three hundred years later, Ptolemy only came up with a figure of 36. The precession of the equinoxes refers to the gradual shift in Earths rotation axis. Our planet wobbles like a top as it spins, and over time, this means that the poles of our planet slowly shift the direction in which they point in space. Its why our north star changes throughout a 26,000-year cycle. Right now the north pole of our planet points to Polaris, but in the past, it has pointed to Thuban and Beta Ursae Majoris. Gamma Cepheii will become our pole star in a few thousand years. In 10,000 years, it will be Deneb, in Cygnus, all due to the precession of the equinoxes. Hipparchuss calculations were the first scientific effort to explain the phenomenon. Hipparchus also charted the stars in the sky seen with the naked eye. While his star catalog does not survive today, it is believed that his charts included around 850 stars. He also made a careful study of the motions of the Moon. Its unfortunate that more of his writings do not survive. It seems clear that the work of many who followed was developed using the groundwork laid by Hipparchus. Although little else is known about him, it is probable that he died around 120 BC most likely in Rhodes, Greece. Recognition In honor of Hipparchuss efforts to measure the sky and his work in mathematics and geography, the European Space Agency named their HIPPARCOS satellite in reference to his accomplishments. It was the first mission to focus exclusively on astrometry, which is the accurate measurement of stars and other celestial objects in the sky. It was launched in 1989 and spent four years on orbit. Data from the mission have been used in many areas of astronomy and cosmology (the study of the origin and evolution of the universe).   Edited and updated by Carolyn Collins Petersen.

The destruction of communism has made the business climate in Bulgaria more suitable for the American business tycoon Coke. Earlier the communist regime looked suspiciously at the intrusion of the products and organizations from the capitalist countries. On the other hand, Spain had no such political obstacles for the entry of Coke in their market. Spain traditionally a close ally of America and American products never faced many barriers in Spain. This report analyses the macro-environmental analysis of Coca Cola product in Bulgaria and Spain. Coca Cola is currently marketing across different countries and different cultures. One of the major characteristics of Coke’s international marketing strategy is the custom made marketing strategies for each country and region where Coke operates. Coke knows that different countries may have different social, political, economical environmental, legal, cultural and communal factors and each country needs marketing strategies suitable to their characteristics. Even though Coca Cola is marketing same products all over the world, they have realized that even for same product, different marketing techniques needed in different countries. Since 1990, Bulgaria has embraced parliamentary democracy as communism failed to fulfil the needs of the people. Spain on the other hand is a parliamentary representative democratic constitutional monarchy since 1975. In short both these countries are under democratic administration at present which is a good sign for Coke’s business hopes in these countries. Historically, communist countries were reluctant in allowing American companies to function in their soil because of suspected spy work. But the current political systems in Spain and Bulgaria offers less resistance to

Megacities in Asia Essay Example | Topics and Well Written Essays - 250 words

Megacities in Asia - Essay Example Oxidation causes arseno-pyrite minerals to release arsenic. Further, when the water table is lowered by over exploiting groundwater in irrigation procedures, more arsenic is released (Karim, 2000). The most likely remediation strategy to be implemented is the use of innovative alternative drinking water sources. Although restoring the natural flow of rivers and level of ground water would have been the ideal situation, the time implications in achieving such goals are not practical. Examples would include harvesting rainwater, pond sand filters, Ranney wells and infiltration galleries. These methods are recommended because they are less costly than most of the proposed solutions. Secondly, they have the potential of providing drinking water for longer terms than the rest of the proposals. For example, harvesting rain water may incur an initial cost of putting up the structures, but once that is done, no more expenses are expected. The same applies for ponds, which require minimum
