All About Like
All About Like All About Like All About Like By Mark Nichol Like is one of the most versatile of words, with senses encompassing multiple parts of speech. Hereââ¬â¢s a review of its various meanings and uses. As a verb, like means ââ¬Å"enjoy,â⬠ââ¬Å"feel affection for,â⬠ââ¬Å"regard favorably,â⬠ââ¬Å"thrive in,â⬠or ââ¬Å"wish to have.â⬠It can also mean ââ¬Å"approveâ⬠or ââ¬Å"prefer.â⬠The noun like refers to preference or something that one likes. In recent years, it has acquired the sense of ââ¬Å"an acknowledgment given online in approval of content another person has posted.â⬠The word appears as a noun in idiomatic phrases such as those in ââ¬Å"We havenââ¬â¢t seen the likes of him for a long timeâ⬠(meaning ââ¬Å"Someone resembling him hasnââ¬â¢t been seen for a long timeâ⬠) and ââ¬Å"Sheââ¬â¢s partial to lavender and the likeâ⬠(meaning ââ¬Å"Sheââ¬â¢s partial to lavender and things that are similar to itâ⬠). As an adjective, like means ââ¬Å"possessing the same or similar characteristics or qualities,â⬠as in ââ¬Å"They finally admitted that they did not have enough like interests to sustain a relationship.â⬠As a suffix, it has an adjectival function. Treatment depends on what precedes it. Most words with the suffix are closed, with no hyphenation, as in ââ¬Å"birdlike movements.â⬠However, if the base word ends with l (ââ¬Å"the cell-like roomâ⬠) or is a proper noun (ââ¬Å"a Christ-like bearingâ⬠), employ a hyphen. The adverb like, stands in for approximately or nearly, as in ââ¬Å"It was more like a dark orange than a pale red.â⬠When informally referring to measurements, the adverb is sometimes used interjectionally: ââ¬Å"It was, like, as long as my armâ⬠or ââ¬Å"He seems to come around every few years, like.â⬠Similarly, it is parenthetically employed in conversational English for emphasis (ââ¬Å"I was, like, astonishedâ⬠) or, paradoxically, to suggest an offhandedness (ââ¬Å"They were, like, hoping somebody would offer them a rideâ⬠). Casually, it can also mean probably, as in ââ¬Å"Iââ¬â¢ll be there in time, like enough.â⬠The preposition like means ââ¬Å"comparable,â⬠ââ¬Å"similar,â⬠or ââ¬Å"typicalâ⬠; thatââ¬â¢s the part of speech that is essential in a simile such as ââ¬Å"The grass, ruffled by the wind, looked like a rolling wave.â⬠As a conjunction, like means ââ¬Å"the same asâ⬠or appears in place of ââ¬Å"as ifâ⬠(ââ¬Å"She looked like she was about to cryâ⬠). Informally, it is employed similarly to the casual adverb to introduce a quotation, paraphrase, or thought (ââ¬Å"Heââ¬â¢s like ââ¬ËDonââ¬â¢t even think about leaving nowââ¬â¢Ã¢â¬ ) or, following itââ¬â¢s, to express a widely held opinion (ââ¬Å"Itââ¬â¢s like, itââ¬â¢s not going to make any difference.â⬠) As a preposition, like is often considered inferior to or even improper as a substitute for ââ¬Å"such as,â⬠but as with some other supposedly undesirable usages, this is acceptable in even formal prose. The adjective like derives from the Old English term gelic, meaning ââ¬Å"similar.â⬠Most of the other parts of speech derived from this usage, but the verb stems from lician, which means ââ¬Å"pleaseâ⬠or ââ¬Å"be pleasing or sufficientâ⬠; the connection is perhaps that to be sufficient is to be suitable, which is to be similar. Words based on the root like include the following: alike: similar likeable: agreeable likelihood: probability likely: seeming to be right, suitable, or true, or very probable; also, promising or attractive liken: compare likeness: similarity likes: preferences likewise: in the same manner liking: the action or feeling of enjoying a person, place, or thing Want to improve your English in five minutes a day?

The Predators of Sea Turtles
The Predators of Sea Turtles Sea turtles have hard shells (called carapaces) that help protect them, but they still have predators. They are also more vulnerable than land turtles because unlike land turtles, sea turtles are unable to retract their heads or flippers into their shell. Predators of Sea Turtle Eggs and Hatchlings There are some predators of sea turtles as adults, but these marine reptiles are most vulnerable when in the egg and as hatchlings (small turtles recently emerged from the egg). Predators of eggs and hatchlings include dogs, cats, raccoons, boars, and ghost crabs. These animals may dig up a sea turtle nest to get to the eggs, even if the nest is 2 feet below the surface of the sand. As hatchlings start to emerge, there is a scent of egg that still is on their bodies, plus the smell of wet sand. These scents can be detected by predators even from a distance. According to the Georgia Sea Turtle Center, threats to turtles in Georgia include the above, plus feral hogs and fire ants, which can threaten both eggs and hatchlings. Once hatchlings emerge from the egg, they need to get to the water. At this point, birds such as gulls and night herons can become an additional threat. According to the Sea Turtle Conservancy, as few as one in 10,000 sea turtle eggs reach adulthood. Olive ridley turtles nest in huge groups called arribadas. These arribadas can attract animals such as vultures, coatis, coyotes, jaguars, and raccoons, who may gather near the beach even before the arribada begins. These animals dig up nests and eat eggs and prey on nesting adults. Predators of Adult Sea Turtles Once turtles make their way to the water, both juveniles and adults can be prey for other ocean animals, including sharks (especially tiger sharks), orcas (killer whales), and large fish, such as grouper. Sea turtles are built for life in the water, not on land. So adults can also be vulnerable to predators such as dogs and coyotes when they go up upon beaches to nest. Sea Turtles and Humans If turtles survive their natural predators, they still face threats from humans. Harvest for meat, oil, scutes, skin, and eggs decimated turtle populations in some areas. Sea turtles face development on their natural nesting beaches, which means they have to contend with such things as artificial light, and loss of habitat and nesting sites due to construction and beach erosion. Hatchlings find their way to the sea using natural light, the slope of the shore, and the sounds of the ocean and coastal development can interrupt these cues and make hatchlings crawl in the wrong direction. Turtles may also be caught as bycatchà in fishing gear, which was such a problem that turtle excluder devices were developed, although their use is not always enforced.à Pollution such as marine debris is another threat. Discarded balloons, plastic bags, wrappers, discarded fishing line, and other trash may be mistaken by a turtle for food and be accidentally ingested, or the turtle may become entangled. Turtles may also be struck by boats. How to Help Sea Turtles A sea turtles life may be fraught with danger. How can you help? If you live in a coastal area: Dont feel wildlife - you may attract turtle predators.Dont let your dog or cat run loose.Watch for sea turtles when boating.Do not disturb or shine lights near nesting sea turtles.Turn off outside, ocean-facing lights during sea turtle nesting season.Pick up litter on the beach. Wherever you live: Dispose of trash responsibly, and keep a lid on your trash when its outside. Trash even far from the ocean can make its way there eventually.Never release balloons - always pop them and dispose of them in the trash. Use balloon alternatives whenever possible during your celebrations.If you eat seafood, research what you eat and eat seafood that is caught without threatening turtles.Support sea turtle conservation/rehabilitation organizations, even international ones. Sea turtles are highly migratory, so recovery of turtle populations depends on protection in all their habitats. References and Further Information: Network for Endangered Sea Turtles.

Marketing of nuclear power Essay Example | Topics and Well Written Essays - 2500 words
Marketing of nuclear power - Essay Example Now looking at the future of the world energy market is to consider trends in energy consumption at the end use sector level. With the exception of the transportation sector which is almost universally dominated by petroleum products at present, the mix of energy use in residential and business sector (commercial & industrial) can vary worldwide from country to country depending on the combination regional factors such as the availability of the energy resources, the level of economic development and political, social and demographic factors. Now the worldwide energy market is expected to increase on an average by 2% per year over the forecast period from 2002 to 2025, slightly lower than the 2.2% average annual growth rate from 1970 to 2002. Total energy use is projected to grow from 412 quadri billion British thermal unit(Btu) in 2002 to 645 quadri billion Btu in 2025. Emerging economies account for much of the projected growth in marketed energy consumption over the next two decades with energy use in this group be more than double by 2025.Economic activity as measured by gross domestic product (GDP) is purchasing power parity terms, is expected to expand 5.1% per year in the emerging economies as... s expected to expand 5.1% per year in the emerging economies as compared with 2.5% per year in mature market and 4.4% in transitional market economies. On the basis of consumption: Domestic or Residential sector: The residential sector is defined by the energy consumed in household excluding transportation uses. The type of energy used by household varies from country to country depending on income levels, natural resources and available energy infrastructures. Households in mature market economies use energy more intensive than those in less developed economies primarily because of higher income level. In Mexico, country's residential energy consumption projected to increase by 3.4% per year in USA it is 1.6% while in Western Europe it is expected to increase by 0.4% per year from 2002 to 2025.Residential electricity use in transitional economies is projected to grow nearly double in the projected period of 2002 to 2025. Household energy use is projected to increase most rapidly in the emerging economies in the coming decades. In this region the population growth and urbanization will increase and create a larger demand for residential energy services. As a result the emerging economies in 2025 are projected to nearly equal the mature market economies in residential energy use. Business segment: a. Commercial sector: Often referred as the services sector or the services and institutional sector, consists of business organization that provides services. Due to slow rate of population growth in mature market as a whole expected demand in this region projected to grow by 1.9% per year from 2002 to 2025. Many countries in transitional economies expected to see their population decline during the period 2002 to 2025; commercial sector electricity consumption is projected

Setting a Home Network Term Paper Example | Topics and Well Written Essays - 2000 words
Setting a Home Network - Term Paper Example Besides the easy handling of the XP ICS, by the XP computer as the ICS host the other benefit is using the internet connection Firewall. 3. Choice of a network technology The commonly available choices are the Ethernet and wireless LANs. When using an Ethernet LAN its essential to have the network interface card, or the NIC that ought to be fitted in each computer and then run the cabling between the computers. Just in case you donââ¬â¢t find the idea of opening the computer to fit/or to install the network card good for you, then get yourself a USB adaptor to assist you. Considering the size of the network, you may also find it necessary to have a network hub or router to provide interconnection between the PCs on the LAN. Two PCs can get by using an RJ-45 crossover cable; three or more computers require a hub or a multi ââ¬â speed hub (also called a switch). For high ââ¬â speed internet connection, a high ââ¬â speed router is a good option. If you decide to have a wi reless LAN as your choice, you may also need an NIC for each and every PC (although there are versions that use USB adaptors as well) the major advantage of home environments is that a wireless LAN eliminates the need for cabling. Although on the contrary wireless LANs tend to be slower, less robust and most likely more expensive than the traditional Ethernet LANs. Wireless LANs particularly do not live up to their stated working range and you may encounter factors such as your construction and design in your home, in addition to interference from other devices which affect the performance of your wireless LAN. You may also need to add an expensive Access point to be able to extend the range of the LAN and more so it may not be sufficient. What is essential here is that if you make a choice of going wireless route, then ensure that the store will refund your money if the LAN will proof not to be reliable in performance within the range specified. 4. Make a list of hardware needed Co me up with a list that outlines the hardware you need for each computer, without forgetting any cabling, and purchase them. If you find it a little dazzling to make an appropriate choice and the configurations, then consider purchasing a networking kit. This kind of kits contain all that is needed to set up a two or three Pc network. If itââ¬â¢s possible, then look up for hardware that contains the Windows XP logo that indicates its fully compatible with XP. 5. Install the adaptors. Make an installation of the network adaptors and also install your modem on the ICS host computer(you may also let the computers connect to the internet independently by installing modems on each one of them) 6. Cable the computers Physically cable the computers and hubs or routers together, as usual you may not need to undertake this if you have decided to use the wireless option. When installing an Ethernet network and you have a lot of cabling work to be done then its preferable that you get a prof essional to come in and do this kind of work for you. It may not be cheap but to ensure that the work is perfectly done with minimal damage done to the walls, ceilings and the floors. 7. Switch it on Power all computers, printers and other peripherals. 8. Connect the ICS host Get to the ICS host computer and ensure itââ¬â¢s connected to the internet. 9. Run the network setup Wizard on

Mortality Rate Research Paper Example | Topics and Well Written Essays - 500 words
Mortality Rate - Research Paper Example Adjusting the mortality rates is important if we have to compare populations of age-sex groups or belonging to different time periods. ââ¬Å"In order to avoid errors in interpretation, mortality rates must be adjusted to a common population with a known age structureâ⬠(Hispanic Health Homepage, 2001). Thus, we standardize the mortality rates. This also called adjustment to calculate mortality rate and its significance is seen when we observe that there are many diseases that occur at different rates in different ages. For examples, cancer occurs most often in elder people while physical injuries happen to younger age group within the same population. So, when we age-adjust the statistics, we can tell what health conditions the population is suffering from and what are the mortality rates when compared with other populations (Department of Health, 1999). If we use unadjusted mortality rates, then this comparison is not possible and it also becomes difficult to interpret the dif ferences between the mortality rates of different populations or different time periods. Question2 Adjusted and unadjusted mortality rates are useful for healthcare organizations in decision making process in that when a speedy result is required in making comparisons of health conditions or mortality, then crude or unadjusted rates are sufficient.

Orbids of the Skull
Orbids of the Skull Sarah Ferreira 1.INTRODUCTION The orbits of a human skull is the space in which the eye and itââ¬â¢s appendages are located. The two orbits in the human skull are conical ââ¬Å"holesâ⬠that opens into the midline of the face and point back into the head. Each orbit includes an apex, four walls and a base. The functions of these orbits is firstly to keep the eye ââ¬Å"safeâ⬠from any mechanical injury and secondly to supply an entrance for the optic nerve(that transports visual information from the eyeââ¬â¢s retina to the vision centers in the brain through electrical impulses) to the brain. A thorough understanding of the anatomy of the orbits of the human skull is very important to any doctor in order to comprehend any disorders that patients might experience that are related to the eye socket itself, as well as to understand the surgical management of this region in the human skull. 2.The orbit of the skull 2.1The general location of the orbits in the human skull: The orbit in the human skull lies anterior to the temporal fossa (laterally) and anterior to the middle cranial fossa (medially). Itââ¬â¢s also situated superior to the maxillary air sinus, lateral to the nasal space as well as below the anterior cranial fossa. 2.2The shape of the orbit of the skull: The shape of the orbit in the human skull looks like a pyramid that has four distinctive sides (ââ¬Å"wallsâ⬠), but as one moves posterior, it becomes three sided( toward the apex). The most posterior portion of the pyramid shaped orbit is the apex (of the orbit) and itââ¬â¢s positioned at the craniofacial junction. ( The apex is also where the optic canal (that contains the central retina vein, ophthalmic artery, symphathetic nerve and optic nerve) opens into the posterior part of the orbit and it forms the tip of this pyramid shaped ââ¬Å"cavityâ⬠or structure.) 2.3The bones of the orbit of the skull and their bone classification: There are seven bones that make up the orbit namely the: 1)The Maxillary bone(that is also classified an irregular bone) 2)The orbital plate of the Frontal bone(that is also classified as an irregular bone) 3)The Zygomatic bone(that is also classified as a flat bone) 4)The Ethmoidal bone(that is also classified as an irregular bone) 5)The Lacrimal bone(that is also classified as a flat bone) 6) The Palative bone (that is also classified as an irregular bone) 7) The Sphenoid bone (that is also classified as an irregular bone) All of the above mentioned bones also form part of the human skull. The orbit also contains fissures and fossae where various blood vessels and nerves pass through. 2.4The walls of the orbit The orbit as mentioned earlier consist of four sides or ââ¬Å"wallsâ⬠. The facial and cranial bones that forms the structure of the orbits also forms these four walls. The walls of the orbit of the skull are as follows: 1)The superior wall/ ââ¬Å"roofâ⬠2)The lateral wall 3)The inferior wall/ ââ¬Å"floorâ⬠4)The medial wall. 3Introduction to the bones of the orbit and the orbital walls that they form: The superior margin and most of the roof of the orbit are formed by the frontal bones of the orbital plate. The inferomedial margin and the floor of the orbit is also formed by the maxilla bone. The anterior part of the lateral wall and the inferolateral margin of the orbit is also formed by the zygomatic bone. Much of the medial wall of the orbit is also formed by the lateral mass of the ethmoid bone. There are also a number of ways in which the sphenoid bone contributes to the structure of the orbit: Firstly, the lateral wall posterior to the Zygomatic bone is constituted by the greater wing of the sphenoid bone and secondly the posterior margin of the roof (or superior wall) is formed by the lesser wing of the sphenoid bone.Thirdly the optic canal (that provide a passage for the optic canal and the optic nerve into the orbital space) which is in the apex of the orbit, is also framed by the roots of the lesser wing of the sphenoid bone.( Thisâ⬠rootsâ⬠of the lesser wing a lso connects it to the body of the sphenoid bone.) The medial wall of the orbit( that is between the frontal process of the maxilla and the lateral mass of the ethmoid is completed by the small, curved , lacrimal bone. The posterior angle of the floor or inferior wall is completed by the orbital process of the palatine bone that is insinuated behind the maxilla and underneath the ethmoid bone. 3.1The superior wall or ââ¬Å"roofâ⬠The lesser wing of the sphenoid bone constitutes/forms the posterior margin of the superior wall and also surrounds the optic canal( that ââ¬Å"acâ⬠as a channel for the optic nerve and ophthalmic artery). Thus the optic canal is situated posteriorly in the wing of the sphenoid bone that is smaller i.e. the lesser wing and this canal also communicates with the middle cranial fossa. (A fossa is a hollow or a shallow depression.) The superior margin of the bony cavity that contains the human eyeball are formed by the orbital plate of the frontal bone and this bone forms almost everything of the superior wall of the orbit except the posterior extremity of the superior wall. This specific part (the posterior extremity) is formed by the lesser wing of the sphenoid bone. The superior orbital fissure is also situated posteriorly between the greater wing of the sphenoid bone and the lesser wing of the sphenoid bone. (This fissure also communicates with the middle cranial fossa and also provides a passage for the frontal nerve, lacrimal nerve, oculomotor nerve, trochlear nerve, abducent nerve, nasociliary nerve and lastly the superior ophthalmic vein). A fossa for the lacrimal gland is made by the roof that rises laterally above the level of the rim of the orbit. The superior orbitals marginââ¬â¢s contour is laterally sharp and medially round. The supraorbital notch also leads from the orbit onto the face at the point of transition. On the frontal bones maxillary process, a small trochlear fossa that is in the anterior medial angle of the orbit gives an attachment to the trochlea. 3.2The Medial wall The medial wall consists of 4 bones namely: the sphenoid bone, ethmoid bone, lacrimal bone and maxillary bone. Thus the frontal process of the maxilla largely constitutes the medial margin of the orbit. The shorter maxillary process of the frontal bone are also met by the rising of the frontal process of the maxilla. The maxilla itself contributes little more than the rim to the medial orbital wall. The lacrimal bone, that has an irregular shape, articulates vertically with the frontal process of the maxilla within the orbit. The lacrimal sacââ¬â¢s fossa are framed or formed by both of these bones. The bony nasolacrimal canal is also continuous with the fossa which also proceed into the inferior nasal meatus below( that is the gap(space) covered by the inferior nasal concha. Posteriorly the fossa is bounded by a vertical ridge (that is named the lacrimal crest) and from this the orbital surface of the lacrimal bone increases posteriorly to meet the lateral mass of the ethmoid bone. The upper part of the nasal cavity are separated from the orbit by the lateral mass of the ethmoid bone. The lateral mass of the ethmoid is pneumatized extensively by the ethmoid air cells and in many skulls this gives the medial wall the appearance or likeness of an unviolated honeycomb. The thinnest part of the wall is the lamina papyracea which means a ââ¬Å"layer as thin as paperâ⬠The frontoethmoidal suture is where the medial wall and the roof of the orbit mets. Across this boundary, the ethmoid air cells of the lateral mass extend upward into the overlying frontal bone.The anterior and posterior ethmoidal foramina open out of the orbit along the suture line into canals that pass horizontally between adjacent air cells. The first leads onto the upper surface of the cribriform plate, the second into the posterior ethmoidal and sphenoid air sinuses. 3.3The Lateral wall The Zygomatic bone forms the lateral margin and wall of the orbit and the greater wing of the sphenoid bone, completes this lateral wall The greater wing of the sphenoid also does not articulate with the lesser wing of the sphenoid or the maxilla bone and because of this there is two gaps posteriorly. The first ââ¬Å"gapâ⬠is the superior orbital fissure that is located between the lateral wall and the superior wall and the secondâ⬠gapâ⬠is the inferior orbital fissure that located between the floor( also called the inferior wall ) and the lateral wall. These 2 fissures converge in the apex of the orbit of the skull that is just lateral to he optic canal. The inferior orbital fissure is roughly in line with the zygomatico-orbital foramen that opens in the orbital surface of the zygomatic bone.h This Zygomatic orbital foramen can be doubled or multiple or it may be so hidden as to be virtually missed by the human eye. 3.4The floor or inferior wall The maxilla(medially) and the Zygomatic bone(laterally) forms the inferior margin of the orbit that is also named the floor. The floor is also the shortest of all the orbitââ¬â¢s walls) The whole of the orbit floor is also virtually formed by the maxilla bone and the Zygomatic bone. The maxilla bone constitutes almost all of the surface of the floor except the extreme lateral angle.The roof of the maxillary air sinus is also formed by the bone of the floor that is very thin. The floor is completed in front of the apex by the small orbital process of the palatine bone.The inferior orbital fissure is left by the prominent infraorbital groove and this prominent infraorbital groove runs directly forward on the surface of the maxilla.This groove (halfway across the floor of the orbit) becomes continuous with the infraorbital canal( thus the infraorbital groove (and canal) is located in the inferior wall of the orbit and in the maxillaââ¬â¢s orbital plate and it ââ¬Å"transferâ⬠the blood vessels and the infraorbital nerve) , which eventually ends in the infraorbital foramen ( on the anterior surface of the maxilla below the orbital margin. 4The neurovascular portals in the orbitââ¬â¢s walls and in the apex( some of them ( the nerves and arteries that go through passages in the orbit and apex) are discussed below.): 4.1The apex From the middle cranial fossa the optic canal opens directly into the apex of the orbit. The ophthalmic branch of the internal carotid artery as well as the optic nerve(thatââ¬â¢s covered by all meningeal layers) goes through the optic canal. Between the orbit and the middle cranial fossa the main passageway is the superior orbital fissure. 4.2The Medial wall The anterior and posterior ethmoidal branches of the nasociliary nerve are transmitted by the anterior and posterior ethmoidel foramina. Corresponding branches of the ophthalmic artery and veins draining to the superior ophthalmic vein also accompanies them. 4.3The Roof The supraorbital nerve and vessels are transmitted by the supraorbital notch( or foramen) onto the forehead. The supraorbital nerve is the larger extension of the frontal nerve and the artery is from the ophthalmic artery. 4.4Floor The infraorbital and zygomatic nerves and vessels are ââ¬Å"transferredâ⬠by the inferior orbital fissure. The infraorbital nerve and vessels are carried from the inferior orbital fissure to the infra orbital foramen(through this foramen they appear onto the face) , by the infraorbital canal and the infraorbital groove. 4.5Lateral wall The zygomatic orbital foramen transmits the zygomatic vessels and the zygomatic nerves into the zygomaric bone( this happens beyond the lateral end of the inferior orbital fissure) The Zygomatoc facial foramen is the passageway through which the zygomatico facial nerve and vessel appear on to the head. It may happen that there are two foramens rather than one and this is not unusual. The zygomaticotemporal foramen is also the passageway through which the zygomaticotemporal nerve and vessels emerge into the temporal fossa. Picture of the orbits 5Possible clinical application in Radiography In Radiography(orbital Radiogrpahy) injury to they eye or trauma to the eye are detected by orbital x rays. ( Orbital x-rays are x-ray images of the left and right eye sockets in the human skull. It also includes the frontal sinuses and maxillary sinuses). Orbital x-rays are also used to detect changes in the structure of the eye, which may lead to various diseases, as well as to detect foreign bodies in the eye that a opthalmoscope( thatââ¬â¢s an instrument that detect foreign bodies in the eye) cannot ââ¬Å"spotâ⬠In the Radiography department there is going to be patients who have fractures and diseases of the orbitals. Some of the fractures encountered could be a fracture of the zygomatic arch, displacement of the zygomatico-frontal suture, infraorbital fractures, etc. It will be expected of every qualified Radiographer to take orbital x-ray images of these patients orbitals. To be able to do this a Radiographer must be familiar with complex anatomy of the orbits in the skull and it associated soft tissue . For example if a patients thatââ¬â¢s been in a car accident has fractured his orbitals and this resulted in a fracture of the zygomatic arch, then it would be expected of a radiographer to know where this zygomatic arch is located in order to take an orbital x-ray image of that area. A Radiographer must also have sufficient knowledge to be able take an orbital x ray image in the correct angle or to discern when to take several x-rays (from different angles) in order to show the fractur e to the zygomatic arch more clearly. It may happen in serious emergency cases that the Radiographer must firstly look for any damage on the patients face(before he/she can take an x-ray) , and if this radiographer doesnââ¬â¢t know where the facial bones or orbital bones is located then it wouldnââ¬â¢t help taking an image of the wrong facial bone, because that would be of no usage to the doctors seeing the orbital x-rays, because they want to see the fracture in order to make a diagnosis. A doctor may also ask a radiographer if she can see anything abnormal on the x-ray and then again this radiographer must be able to identify the bones and the location of the fractures. Thus it is very important for a radiographer to know where the orbitals lie and of what bones it consists. 6CONCLUSION From the above mentioned research I conclude that it is very necessary for a radiographer to know the orbits of the eye in order to take valuable x-ray orbital images of this area. The orbitals of the human skull is also of utmost importance , because of the fact that it contains the eye, ( a vital organ that is used in almost every activity of a human being ex. from reading the newspaper to crossing the street) and thus patients that has any damage to this area need to be helped swiftly before a minor orbital injury could proceed to a life threatening injury and results in the patient losing his eye. A Radiographer also pays an important role in ââ¬Å"helpingâ⬠these patients and must know the anatomy of the orbits in order to supply the doctors with the needed medical information that would help doctors to make a diagnosis.

Edgar Allan Poe :: essays research papers fc
Edgar Allan Poe 1809-1849 In personal appearance, Poe was a quiet, shy-looking but handsome man; he was slightly built, and was five feet, eight inches in height. His mouth was considered beautiful. His eyes, with long dark lashes, were hazel-gray. Edgar Poe was born in 1809 in Boston. It was in Richmond that Poe grew up, married, and first gained a national literary reputation. Many of the places in Richmond associated with Poe have been lost, but several still remain. Family Father: David Poe, an actor Mother: Elizabeth Poe, an actress Foster parents: John Allan, Tobacco merchant and his wife, Frances Allan, cared for Poe while he was young, but never legally adopted him. Wife: Poe married his cousin Virginia Clemm Occupations â⬠¢ Soldier â⬠¢ Editor and literary critic â⬠¢ Author Chronology Edgar Poe is the second of the three children of David Poe and Elizabeth (Arnold) Poe, both of whom were professional actors and members of a touring theatrical company. Mr. Placideââ¬â¢s Theatre Company in Boston employed Poeââ¬â¢s natural parents, David and Elizabeth Arnold Poe. They had been married in Richmond while on tour in 1806. Edgar Allan Poe was born January 19, 1809 in Boston, Massachusetts, but he considered Richmond his home, and called himself "a Virginian," where his mother had been employed as an actress. David Poe, unknown due to his more famous wife, his own promising career ruined by alcoholism, Edgarââ¬â¢s father, deserted the family when Edgar was still an infant; nothing conclusive is known of his life thereafter. While appearing professionally in Richmond, Virginia, Poe's mother became ill and died on December 8, 1811, in Richmond at the age of twenty-four. Poe's mother, Elizabeth, was buried in the churchyard of St. John's Episcopal Church where her memorial stone may be seen. St. John's is the oldest church in Richmond and is famous as the site of Patrick Henry's rousing "liberty or death" oration shortly before the Revolutionary War. The Richmond Theatre where Edgar Poe's mother had performed burned to the ground on December 26, 1811, only eighteen days after her death. The fire took the lives of many Richmonders including the Governor of Virginia, George Smith and his wife. At the site of the tragedy on East Broad Street, Monumental Episcopal Church was erected as a memorial to the victims. Her three children, who would maintain contact with one another throughout their lives, were sent to live with different foster families. Richmond families took in the other two children who were Rosalie, only eleven months old, by William and Jane Scott Mackenzie.
