10 Geography Facts About Florida

10 Geography Facts About Florida Capital: Tallahassee Populace: 18,537,969 (July 2009 gauge) Biggest Cities: Jacksonville, Miami, Tampa, St. Petersburg, Hialeah, and Orlando Region: 53,927 square miles (139,671 sq km) Most noteworthy Point: Britton Hill at 345 feet (105 m) Floridaâ is a state situated in the southeastern United States. It is flanked by Alabama and Georgia toward the north, while the remainder of the state is a landmass that is circumscribed by the Gulf of Mexico toward the west, the Strait of Florida toward the south, and the Atlantic Ocean toward the east. As a result of its warm subtropical atmosphere, Florida is known as the daylight state. Florida Geography Facts Florida is a well known vacationer goal for its numerous sea shores, untamed life in regions like the Everglades, huge urban communities, for example, Miami, and amusement parks like Walt Disney World. Find 10 more topography realities about Florida. 1. Numerous Native Americans Lived Here Florida was first occupied by various diverse Native American clans a large number of years preceding any European investigation of the locale. The biggest known clans in Florida were the Seminole, Apalachee, Ais, Calusa, Timucua, and Tocabago. 2. It Was Discovered in 1513 On April 2, 1513, Juan Ponce de Leã ³n was one of the main Europeans to find Florida. He named it as the Spanish expression for bloomed land. Following Ponce de Leã ³ns revelation of Florida, both the Spanish and the French started to fabricate settlements in the locale. In 1559, Spanish Pensacola was built up as the primary lasting European settlement in what might turn into the United States. 3. Its the 27th State Florida formally entered the U.S. on March 3, 1845, as the 27th state. As the state developed, pilgrims started to drive out the Seminole clan. This brought about the Third Seminole War, which kept going from 1855 to 1858 and brought about a large portion of the clan being moved to different states, (for example, Oklahoma and Mississippi). 4. The travel industry Drives the Economy Floridas economy depends for the most part on administrations identified with the travel industry, money related administrations, exchange, transportation, open utilities, assembling, and development. The travel industry is the biggest area of Floridas economy. 5. The State Relies on Fishing Angling is likewise an enormous industry in Florida. In 2009, the state made $6 billion and utilized 60,000 Floridians. A huge oil slick in the Gulf of Mexico in April 2010 compromised both the angling and the travel industry enterprises in the state. 6. Its Low-Lying The vast majority of Floridas land zone is based on a huge promontory between the Gulf of Mexico and the Atlantic Ocean. Since Florida is encircled by water, quite a bit of it is low-lying and level. Its most elevated point, Britton Hill, is just 345 feet (105 m) above ocean level. This makes it the least high purpose of any U.S. state. Northern Florida has an increasingly differed geology, with delicately moving slopes. Be that as it may, it additionally has generally low rises. 7. It Rains Year-Round Floridas atmosphere is profoundly influenced by its sea area just as its southern U.S. scope. The northern pieces of the state have an atmosphere that is viewed as moist subtropical, while the southern parts (counting the Florida Keys) are tropical. Jacksonville, in northern Florida, has a normal January low temperature of 45.6 degrees F (7.5 degrees C) and a July high of 89.3 degrees F (32 degrees C). Miami, then again, has a January low of 59 degrees F (15 degrees C) and a July high of 76 degrees F (24 degrees C). Downpour is basic all year in Florida. The state is additionally inclined to tropical storms. 8. It Has Rich Biodiversity Wetlands like the Everglades are basic all through Florida and subsequently, the state is wealthy in biodiversity. It is home to many jeopardized species and marine warm blooded creatures like the bottlenose dolphin and the manatee, reptiles like the gator and ocean turtles, huge land vertebrates like the Florida puma, just as aâ plethora of flying creatures, plants, and creepy crawlies. Numerous species additionally breed in Florida because of its gentle atmosphere and warm waters. 9. The People Are Diverse, Too Florida has the fourth most elevated populace of any state in the U.S. what's more, it is one of the countrys quickest developing. An enormous bit of Floridas populace is viewed as Hispanic, yet most of the state is Caucasian. South Florida likewise has huge populaces of individuals from Cuba, Haiti, and Jamaica. Furthermore, Florida is known for its huge retirement networks. 10. It Has Many Higher Education Options Notwithstanding its biodiversity, huge urban areas, and acclaimed amusement parks, Florida is additionally known for its all around created college framework. There are various enormous state funded colleges in the state, for example, Florida State University and the University of Florida, just as numerous huge private colleges and junior colleges.

Journal 1 – The Metamorphosis

The initial passage of this short story starts with the presentation of Gregor Samsa as a recently changed bug. The storyteller's aim with respect to this abrupt expressing of Gregor's new physical shape, is maybe to pass on Gregor's own amazed and befuddled sentiments into the peruser's psyche. The storyteller appears to envision what the peruser is thinking, as he quickly expresses that Gregor is changed, and what shape he presently has. The storyteller pushes his depiction to unfurling the specific forms of Gregor's body. He takes the point of view of Gregor, looking down on his own body, maybe to elevate the striking quality and merciless mental stun of the primary vision of his â€Å"numerous legs, which were miserably meager contrasted with the remainder of his mass, waved vulnerably before his eyes. † The peruser is along these lines empowered, through this first-individual perspective, to picture that exact picture, which innately enables the peruser to more readily comprehend the impact of the change through Gregor's point of view. The passage specifying Gregor's transformation is trailed by a depiction of his room and of his non-bug life. The peruser sees that where the principal passage was inclining towards structure and a cognizant and exact portrayal of Gregor, this section appears to comprise of more irregular considerations than all else. Maybe Gregor's psyche is meandering about his room, attempting to revamp his human character, though the past section had totally broken his idea of mankind. We can find in the accompanying statement exactly how decided Gregor is to re-discover his mankind, † What has transpired? he thought. It was no fantasy. His room, a customary human room, just rather excessively little, lay calm between the four natural dividers. † Firstly, the way that Gregor states obviously that he lived in a decent, human room appears to be odd, as he wants to qualify the ordinariness of his place of habitation through it's ‘human' bid, rather than, state its ‘roomy' or ‘comfortable' advance. Moreover, the depiction of his room proceeds in its idiosyncrasy, as Gregor feels constrained to additionally harden the commonplace ness of his room through its ‘four recognizable dividers'. It appears that Gregor feels additionally constrained to make his room typical by portraying it as being of regular measurements, henceforth the four dividers, which are natural †a complexity maybe to his recently obtained awkward sentiment of not having a place, of being odd †thus the bug like shape. The apparently xenophobic characteristics of his new character truly struggle with the individual he used to cause himself to be. As he states, â€Å"Above the table on which an assortment of material examples was unloaded and spread out †Samsa was a business explorer †(†¦ † The position he held, assumedly still has, of being a business voyager would persuade that Gregor was not withdrawn at all, in truth the peruser could expect that Gregor filled in as a voyager as a result of his partiality with individuals. However the way where he presently portrays his room maybe recommends that a more profound change had happened, one that influenced his fearlessne ss and his character. Lead by loner like remarks, for example, the â€Å"four recognizable walls†, one can see that Gregor may now discover asylum in the closeness of these dividers, instead of looking for the open universe of a voyager. This response is somewhat obvious, as one could accept that any individual would feel crippled subsequent to being changed into a tremendous bug. However where a few people might be influenced just genuinely, this change appears to have influenced Gregor's mind also. Ultimately, the end-portrayal of the woman, â€Å"sitting upstanding and holding out to the observer an enormous hide muff into which the entire of her lower arm had evaporated! † appears to be odd, as Gregor's response to the gigantic hide muff by one way or another appears to be disconnected, similar to it was the first occasion when he had seen it done. Unexpectedly, Gregor tells the peruser that he had as of late confined the image and had set it over his work area, which would persuade that he had taken a gander at the image before hanging it. In addition, his response to the vanishing lower arm might be identified with the way that he no longer has any, which would along these lines clarify his stunned response; the way that a human is being depicted in some light other than a typical one is both startling and horrifying to Gregor, a thought that is clarified again through his response to the image, and maybe in this manner to his physical state.

Splash 2018

Splash 2018 Heyo everyone! Its Mimi again! I recently became a member of MITs Educational Studies Program, a student group that runs a variety of educational events such as Splash, Spark, Cascade, and several others! The program Im focusing on is Splash. If you dont know, Splash is basically MIT students teaching high schoolers about any topic they want. To give you a sense of the range, when I did Splash 2017 (as a senior and before I got accepted to MIT, how time flies!) I did a game design class, early solar system, basic Japanese, partial differential equations (I dont know multivariable calc, I just thought it would be interesting), quaternions, a queer event (oh look, shes being gay again), and a few others that I cant recall at the moment. But seriously, the breadth is absolutely astonishing! There are already over 400 classes! And they all take place on November 17 to 18! There is really one more reason I wanted to talk about Splash: Im gonna teach a class! So basically, I was kind of disappointed by the game design/dev class because it was spoiled with technical issues and bugs that made it rather frustrating. I wanted to correct those issues and also teach about something new and interesting. My class is called Intro to Game Development with Love 3. As the title suggests, the class is about making games using a framework called Love. One of the things that isnt suggested is that its also an intro to programming course, so no real experience is required! One of the reasons I wanted to teach about Love is that it was my primary game framework in both middle school and high school! While I didnt do anything worth while in middle school (except for some dumb game about passing bills in congress and stuff), Im somewhat fond of my high school work. I mean, its still highly amateurish, but kind of charming. One that I made during sophomore year is called Bullet Helloween (There will be a link here to the source code in the future, once I have scrubbed it). You played as a witch who had to shoot down a variety of different monsters (pumpkins, weird skellys, and evil candy corn). One of my favorite aspects of the game is the different effects that the different weapons you use have on the enemies. The ghost ray shoots much faster than all the other weapons, is much stronger against the pumpkin enemies, but causes the skeleton dudes to go much faster. The candy corn weapon travels in an arc and is super effect against candy corn (a slight ref erence to Megaman 2s Metal Man), but causes the pumpkins to gain health and stop moving. Here is a video of it in action: Bullet-Helloween So yeah, come check out Splash. Come take my class :D If you cant make it to MIT, many other schools have Splashes as well. I highly recommend checking them out and trying to go to one if you can! Thats about all I have to say,

Being an Audience Free Essays

The play entitled â€Å"Arsenic and Old Lace† is about the story of comedy towards tragedy and dilemma. It emphasized the main product of the play, which is the elderberry wine that the main characters used to kill and bury people who had no family. Despite of its tragic complexity, the characters build widespread comic elements to lighten the effect of the story. We will write a custom essay sample on Being an Audience or any similar topic only for you Order Now Being an audience is actually a good but hard task. It enables you to understand fully the story and the implications of its resolution but having extra sensitive to the actions, words, the setting of the play in order to incorporate your ideas and imagination towards the whole situations, and sometimes may apply to the reality. The audience will determine whether an event, play or movie is good, better, or best for they could see the whole actions, that they are outside the frame of acting – they are the judge in the court. The original title of this play is Bodies in the Cellar. It began as a stage play opening on January 10, 1941. Arsenic and Old Lace play 1,444 performances on Broadway and 1,332 in London’s West End. The non-musical play conquered stages around the world in many languages – â€Å"Aresnico e Vecchi Merletti – in Italian. In 1944, Arsenic and Old Lace secured its place in the human consciousness with film direct by Frank Capra. The venue of the play in Ohio Theater House Square is an encouraging place to watch. The seats are comfortable and the ambiance is good as if it attracts its audience to participate in the play. Before the beginning of the play, people are talking to their friends and companions regarding their expectations in the story – the characters, the music, and the story as a whole. Some of the audiences observed the scenario of the place in order to be familiarized with the concept of the play. The audiences were approximately 150 to 200 people who are in higher and middle class, mostly whites. Even if there are blacks in the venue, only few of them exist. They sat at the right side of the stage where almost all of them are together. The dress of the audiences in the play manifests to their social status. A group of friends or family who are in the higher status wears dresses that are more beautiful while people in middle class, dress just like the same as going to school or church. They were also excited while chattering and laughing at their friends and family. The audience started to pay attention when the host went to the stage to introduce and orient the audience about the Indian’s game status and play that we are going to watch. After his remarks, lights dimmed. Some of the audiences yelled in excitement but most of us (including me), gazed at the beauty of the stage as the curtain opens. As I notice while watching the play, people at front part and at my both sides are amazed by the characters. Because the characters played very well, they encouraged the audience to become participative through their laughs and yells. The movements of the character are like dances. As the music come along, the actions of their bodies also went through the beat along with their voices and facial expressions. The history of the play did not result any negativities towards the audience but a standing ovation also because of the pure and unique performances of the characters as well as the setting of the play where audience may think that it is true. After the play, the audience made a significant applause to all the characters and the makers of the play. This kind of play is not easy for they need to build extra grave to bury all the bodies that the main characters killed. Aside from this, the plot, characterization, and resolution of the story merged as one to bring the comic tradition of tragedy, fallacy, and curiosity. The impact of the play to the audience made a distinct action throughout the story. The audience remained at their seats without talking to one another. As the twist of the story revealed, almost everyone in the audience reacted as if they were part of the play. As a whole, being an audience in this kind of event is grateful and unbelievable experience. It brings new life to the tradition of old culture where actors and actresses played their roles without the camera but all bare to the naked eyes. That is why it can be said that they are better than those in the television and movies for there are no director’s cut and editor’s cut – all is true and realistic in a fictional setting and environment.

The Asphalt History

Introduction The composition of crude oil is infinitely varied and complex. This is because of the several components that can be derived from crude oil after the separation process of distillation. However, the components derived from crude oil vary with the original location of the crude oil (Barth, 1962, p. 56).Advertising We will write a custom research paper sample on The Asphalt History specifically for you for only $16.05 $11/page Learn More For instance, crude oil found in West Virginia and Pennsylvania has a lot of wax, which may not be found in crude oils found in other regions. On the other hand, crude oil found in California is known to exhibit a lot of asphalt. Among the various components that can be separated from crude oil include lubricating oil, wax, heavy fuel oil, naphtha, tar, and asphalt just to mention a few. In this section, the production, history, and uses of asphalt will be discussed. â€Å"Asphalt is a semi-solid or highly vi scous substance that could be found as natural deposits or could be manufactured from crude oil. Asphalt is black in colour and very sticky given its high viscosity† (Freemantle, 2013, p.1). It is important to note that asphalt is something that we see and step on almost every day. Indeed, asphalt is the core substance in the construction of roads and airplane runways. It is because of the presence of asphalt that roads and runways are black. With this in mind, it can be deduced that asphalt is heavily used globally. For instance, the United States of America alone uses about 70 billion lb of asphalt yearly. However, this usage is expected to increase in future given the high rate of development. A big percentage of the asphalt used today is derived from the distillation process of crude oil. In fact, asphalt happens to be the residual product of crude oil distillation. â€Å"As such, asphalt comprises of saturated and unsaturated compounds as well as aromatic compounds whose composition differs with the source of crude oil† (Barth, 1962, p.56). However, most aliphatic compounds contain sulphur, nitrogen, heteroatoms, and oxygen among other compounds. â€Å"Typical asphalt will be made up of 80% carbon, 10% hydrogen, 6% sulphur, and small quantities of nitrogen and oxygen† (Freemantle, 2013, p.1).Trace elements such as iron, vanadium, and nickel will also be found in asphalt. Most of the aliphatic components have a high polarity, thus easily dissolving in polar substances such as hexane and heptanes. Aliphatic compounds exhibit high polarity due to the presence of functional groups such as amine, alcohol, and carboxyl in their structure. Nevertheless, asphalt is said to be thermoplastic in nature given its polymer network. Above all, asphalt is hard and able to withstand harsh temperature changes and forces hence its use in road construction. Below is an image showing an asphalt particle.Advertising Looking for research paper on geolog y? Let's see if we can help you! Get your first paper with 15% OFF Learn More Fig. 1 (Barth, 1962, p.67) History of Asphalt Asphalt has been in existence for the longest time in history since 4000 B.C. Asphalt was first realized as deposits that occurred naturally on earth. It was thought that these deposits were as a result of ancient remains of living things such as microscopic algae and other diatoms. These remains were found at sea beds, lake bottoms, and mud, which were inhabitants of living things. Having been found in the ancient times, asphalt had several uses including being used in binding of bricks, cementing carvings, waterproofing, and ship caulking among other uses. â€Å"The bible indicates that the Tower of Babel was constructed using asphalt as a binding substance for the bricks† (McNichol, 2005, p.104). This therefore shows that asphalt is as old as the bible. The Dead Sea commonly known as the Palus Asphaltites (Asphalt Lake) by the Romans was the major source of asphalt for the Egyptians. Asphalt air blowing unit Upon distillation, crude oil is bound to recover various products including gases, heavy fuels, naphtha, wax, and asphalt. As mentioned earlier in the paper, asphalt is the residue of crude oil distillation thus being the lowest substance in the distillation unit as depicted in the figure below. Advertising We will write a custom research paper sample on The Asphalt History specifically for you for only $16.05 $11/page Learn More Fig. 2 (McNichol, 2005, p. 107) Crude oil distillation involves two stages of atmospheric and vacuum distillations. Atmospheric distillation entails heating the oil at temperatures above atmospheric pressure thus recovering gases and light density substances such as gasoline, jet fuel, and heating oil. Vacuum distillation is conducted at pressures that are absolute as well as under vacuum conditions of 10-40 mmHg. This stage is meant to recover heavy fuel oil as shown in the diagram below. Fig. 3 (Volodin et al., 2003, p. 213) As depicted in the above diagram, once the distillation process is over, oil with asphalt is extracted and de-asphalted before it goes through the air blowing process. The air blowing process of asphalt entails the use of an air compressor that is sued to blow air through the liquid asphalt that remains after distillation. This process takes place at temperature ranges of 235 to 290 0C (Volodin et al., 2003, p. 213). Asphalt is heated until it attains this temperature range and then held in the blowing tower. Hot air is injected in the blowing tower for a predestined period. The high heated air is introduced into the blowing column through the bottom part of the column. This air is normally meant to agitate mixing of the heated asphalt in a bid to increase the surface area for intended reaction. The air blowing process is carefully conducted to avoid any instances of asphalt combustion. As such, the temperatures a re normally below the asphalt flash point just to avoid the possibility of combustion.Advertising Looking for research paper on geology? Let's see if we can help you! Get your first paper with 15% OFF Learn More The air blowing process involves exothermic reactions since heat is produced. It is important to note that oxygen in the air used in the process causes the asphalt to oxidize. On the other hand, the asphalt is dehydrogenized thus making it increase in molecular size. Several factors affect the reaction rate in the blowing column. These include the temperature used, residence time, the air-to feed ratio, as well as the viscosity and origin of the asphalt fed. Asphalt emulsifying process After the air blowing process, the extracted asphalt undergoes an emulsification process to come up with an asphalt emulsion. The emulsifying process essentially entails mixing of the asphalt with water at reduced melting point temperatures. An emulsion can be simply defined as the dispersion of one liquid’s droplets in another liquid of different densities. Most often than not, emulsions are either oil in water or water in oil mixtures. Common examples of emulsions include butter, creams, and mayonnaise among others. â€Å"An emulsion of asphalt ideally contains 70% asphalt with the rest being water and chemical additives† (Freemantle, 2013, p.1). This is because the emulsion is prepared by mixing asphalt with water in addition to emulsifying agents. The emulsifying agent function is to disperse the asphalt globules thus making them far from each other. This helps in space creation in between the globules for water globules to bind hence forming an emulsion. Through the application of mechanical energy adequate to break down the asphalt into small particles, the emulsion process sets on. The aim of the mechanical energy is to lower the viscosity of asphalt and make it miscible with water and other substances. The reason behind the emulsification of asphalt is to make it workable at different temperatures given the fact that asphalt is normally very hard at low temperatures. Before emulsification, asphalt is of brown colour, which significantly changes to black upo n emulsification. This turning of colour is an indication that the emulsion is broken after the evaporation of the water. It should be noted that the time taken for the water used in emulsification to evaporate and set is dependent on the emulsion type. Below is a typical diagram showing the emulsification process of asphalt. Fig. 4 (Volodin et al., 2003, p. 213) The blending process â€Å"Upon emulsification, asphalt becomes miscible with each other as well as with other liquids in different proportions† (Freemantle, 2013, p.1). This then makes it possible to produce different blends of asphalt that are of different characteristics. The blending process of asphalt is determined by the softening and penetration points of the asphalt hence the need for blending charts. The charts show the softening and penetration points of the asphalts intended to be blended. The meeting point of the two line graphs on the chart is then used during blending. The softening points are determin ed by measuring the viscosity of asphalt using a viscoliner and a graph similar to the one below derived. Fig. 5 Use of asphalt viscosity blending chart (Volodin et al., 2003, p. 215) Examples of asphalt blends Asphalt/wax blends In this type of blend, paraffin wax is blended with asphalt. The fact that paraffin wax has a low melting point of about 600C when blended with asphalt, the outcome product has a lower viscosity than the original asphalt. This blend also has a reduced tackiness especially during low temperatures. Asphalt/ Petroleum oil blends These are commonly referred to as cutbacks. These blends are made from petroleum oil products such as gas oil, kerosene, and naphtha among others. When blended, the product is normally softer than the original asphalt. Types and grades of asphalt produced There are different types and grades of asphalt produced during processing. These types differ in terms of composition, physical characteristics, and appearance. Some of the common t ypes and grades of asphalt include the following: Mastic asphalt: This is commonly known as sheet asphalt. It has a low percentage of asphalt. â€Å"It is mostly used in road construction as well as footpath construction. Some of it is used in flooring and roofing† (Freemantle, 2013, p.1). This is mainly because of its slippery characteristic, which makes it hard to absorb water. Cut-back asphalt: This type is made by blending asphalt with kerosene and then mixing it with aggregate. This makes it environmental unfriendly since it causes pollution. As such, it has been rendered illegal in most parts of the world. As time goes by, the asphalt becomes hard due to the loss of kerosene through evaporation. Hot Mix Asphalt (HMAC): As the name suggest, this type of asphalt is produced at high temperatures of about 1600C. This means that this asphalt is of low viscosity and with less moisture thus very durable. As such, this type of asphalt is preferred for use in highways, airport runways and other areas of high traffic (Volodin et al., 2003, p.214). Warm mix asphalt: The temperatures in this type of asphalt are relatively low, thus allowing the addition of wax and other substances to form emulsions. The process of making this asphalt is deemed environmental friendly because of reduced emission and low consumption of fuel. The only problem is that the warm mix asphalt is not as durable as hot mix asphalt. As such, it is used in areas of low traffic or used to patch damaged hot mix asphalt concrete. Specification and properties of each type of asphalt produced (high penetration, low penetration, etc) Grading of asphalt according to its penetration abilities is a system that began as early as in the 1900s. Penetration of asphalt is determined using a needle of 100 grams, which is inserted in the asphalt at a temperature of 250C. Using this test, the standard needle will penetrate deeper in less viscous asphalt, which is then graded as high penetration asphalt. In low penetration asphalt, the needle will not penetrate or have a shallow penetration. Penetration grading is important in determining the type of asphalt to be used in different climatic regions. In that case, the low penetration asphalt is used in regions of high temperature while the high penetration asphalt used in cold climatic regions. Nevertheless, this method has attracted much controversy with the critics arguing that the method is not ideal, as it does not test fundamental parameters such as viscosity. Uses and application of different types of asphalt Asphalt is mostly used in making asphaltic concrete that is a material for road construction. â€Å"The consumption of petroleum asphalt on asphaltic concrete is approximated at 80% of all petroleum asphalt used in the U.S. It is normally used as glue holding together crushed stones, sand, slag, gravel, and other materials† (McNichol, 2005, p. 67). For instance, rolled asphaltic concrete has the asphaltic binder an d aggregate, cutback asphalt has petroleum solvents, asphalt emulsions contain chemical additives and asphalt, and mastic has less aggregate than rolled asphaltic concrete. Secondly, asphalt is used in roofing shingles, which account for about a fifth of all asphalt used in the U.S. Roofing materials made of asphalt are actually the dominant roofing material in the U.S (McNichol, 2005, p. 34). In China and Japan, asphalt is incorporated in ceramics thus making them waterproof. In France, asphalt is embedded in photography and art where it used to make photographic films that are fitted in cameras. Asphalt is also used in paving of parking lots for vehicles and runways in airports. In addition to this, it is also used in making dam facings, canals, and reservoir linings. Asphalt has also been used in making battery casings and floor tiles. Due to its waterproofing property, asphalt is used to waterproof materials like fabrics. It can also be used in making cattle sprays and treating wooden objects and materials like wooden fence posts. Overall, the usefulness of asphalt comes as a result of its binding property and its waterproofing property. These properties work together to ensure that materials with asphalt are tough, hard, and durable. Conclusion From the above discussion on asphalt, it can be deduced that asphalt is indeed an important component despite being the residue product in crude oil distillation. Asphalt is the product that remains after distillation of crude oil although it could also be found as natural deposits in sea and lakebeds. In order to be rendered appropriate for use, asphalt undergoes various processes such as air blowing, emulsification and blending among others (Barth, 1962, p. 68). Additionally, asphalts are of different types with the main differences being physical properties and applications. Common types include mastic, hot mix, warm mix, and cut back asphalts. Asphalt is the core product in the construction of roads and airport runways (Volodin et al., 2003, p. 214). Other uses of asphalt mentioned in the paper include roofing, flooring, waterproofing and binding just to mention a few. Despite having several uses, asphalt has proven to have significant health impacts especially after prolonged contact with the substance. Asphalt fumes whose common way of exposure is through inhalation, pose health dangers to the respiratory system of a human being. Some of the immediate respiratory problems felt after exposure include cough and through irritation. If not immediately treated, lung cancer could arise. Asphalt fumes have also been depicted to bring about skin rashes, irritation of eye, headache, and fatigue among other minor ailments. Being carcinogenic, asphalt fumes could lead to different types of cancers such as stomach and throat cancer in cases of prolonged exposure. Reference List Barth, E. (1962).
