Different Types of Isolines in Geography

Different Types of Isolines in Geography Topographic maps use a wide variety of symbols to represent human and physical features, including isolines, which are often used on maps to represent points of equal value. The Basics of Isolines and Contour Lines Isolines, also referred to as contour lines, can be used to represent elevation on a map by connecting points of equal elevation, for instance. These imaginary lines provide a good visual representation of  the terrain. As with all isolines, when contour lines lie close together, they represent a steep slope; lines far apart represent a gradual slope. But isolines can also be used to show other variables on a map besides terrain, and in other themes of study. For example, the first map of Paris used isolines to depict population distribution in that city, rather than physical geography. Maps using isolines and their variations have been used by astronomer Edmond Halley (of Halleys comet) and by doctor John Snow to better understand an 1854 cholera epidemic in England. This is a list of some common (as well as obscure) types of isolines used on maps to represent different features of the terrain, such as elevation and atmosphere,  distances, magnetism and other visual representations not easily shown on a two-dimensional depiction. The prefix iso- means equal. Isobar A line representing points of equal atmospheric pressure. Isobath A line representing points of equal depth under water. Isobathytherm A line representing depths of water with equal temperature. Isochasm A line representing points of equal recurrence of auroras. Isocheim A line representing points of equal mean winter temperature. Isochrone A line representing points of equal time-distance from a point, such as the transportation time from a particular point. Isodapane A line representing points of equal transport costs for products from production to markets. Isodose A line representing points of equal intensity of radiation. Isodrosotherm A line representing points of equal dew point. Isogeotherm A line representing points of equal mean temperature. Isogloss A line separating linguistic features. Isogonal A line representing points of equal magnetic declination. Isohaline A line representing points of equal salinity in the ocean. Isohel A line representing points receiving equal amounts of sunshine. Isohume A line representing points of equal humidity. Isohyet A line representing points of equal precipitation. Isoneph A line representing points of equal amounts of cloud cover. Isopectic A line representing points where ice begins to form at the same time each fall or winter. Isophene A line representing points where biological events occur at the same time, such as crops flowering. Isoplat A line representing points of equal acidity, as in acid precipitation. Isopleth A line representing points of equal numerical value, such as population. Isopor A line representing points of equal annual change in magnetic declination. Isostere A line representing points of equal atmospheric density. Isotac A line representing points where ice begins to melt at the same time each spring. Isotach A line representing points of equal wind speed. Isothere A line representing points of equal mean summer temperature. Isotherm A line representing points of equal temperature. Isotim A line representing points of equal transport costs from the source of a raw material.

Critique and conclusion of context & rationale paper Essay - 1

Critique and conclusion of context & rationale paper - Essay Example It is imperative to keep in mind that effective utilisation of water is the key to reduce droughts and floods at the same time. What comes to the rescue is effective design of methods that cater to the immediate requirement of a particular region. One of the best examples is the use of LifeStraw as a water purification method. â€Å"Lifestraw was created by Danish inventor Torben Vestergaard Feandsen. The product could be a lifesaver† (Fridell 58). It is nothing but a tube that one can use to suck water. The water gets purified when it passes through the levels of filtration. This kind of wonderful design is so portable and convenient to use that people do not actually have to set up any complex infrastructure for the same. Thomas Dickson in his book ‘Dansk Design’ has described the implications of LifeStraw on the formidable task of preventing water borne diseases. He says that this product helps in preventing diseases that include typhoid and cholera which result in the deaths of millions every year. Dickson has also presented an interesting point about the lifespan of the product. â€Å"The lifespan of one straw is about 700 litres of water, so with a consumption of two litres a day, the straw can last about a year† (Dickson 550). drained without even considering a reuse plan. Considering the damaging impact that a country can face due to a shortage of water, it becomes imperative to understand the importance of saving every drop of water that can be saved. And in doing so, it is an interesting fact to notice the diversities in different regions. If some places need to conserve water due to less rainfall, some have to do that to prevent water loss. Over the years, several designs have evolved which are tailor made for the particular environment. ‘Raincatch’ is one such example that serves as an easy water harvesting method. It resembles a raincoat with an enhanced

Clausewitz, Jomini, WWII and Operation Overlord Essay

Clausewitz, Jomini, WWII and Operation Overlord - Essay Example The paper tells that Jomini served in the Russian and French armies in the 19th century during the Napoleonic wars. He contributed largely on the terms used in modern U.S theory and doctrine. Jomini believed that war was a science and with careful study on rules one could discover its conduct. According to Jomini he depicted strategy as art of war upon the map, which comprehended the entire theater of war. â€Å"The main tactic being posting troops in accordance with the accidents of the ground, of placing them into battle, and art of fighting upon the ground, in contradiction to planning upon a map†. Jomini further stated that a defensive war had its advantages when wisely conducted. He depicted passive defense as being pernicious and the active on the other side accomplishing greater success. Jomini’s principle on political war was that the cause of defensive war is to protect the countryside that was being threatened by the enemy, and all operations to be designed to retard his enemy’s progress. This is to be achieved by increasing difficulties and obstacles in the enemy’s way, however taking care not to compromise one’s own army. The idea behind it was that for one to invade, he does so with intention of superiority. The defense on the other hand desires delay till the adversary is weakened by fatigues, marches and sending off detachments to his progress. These ideas by Jomini are important as they are the only ones that were worth considering when it comes to modern war, especially the strategy of exhaustion used to eventually strangle the Confederacy. (Archer 130). Williams in his book Lincoln and his Generals found that most of Jomini’s ideas were seen as misleading and isolated, in many cases would lead to high casualties, uncertain battles, and a war that drug on for so long (Williams 204). Clausewitz ideas on war According to Clausewitz war was a tragic and complex enterprise, always threatening to break away from human control (Archer 126). Bartholomees in his article states that much of what Clausewitz purported was either ordinary or 19th century specific with an exception of three ideas (Bartholomeees 21). First his encouragement of seeking battle. In his book he states that â€Å"†¦ pursuit makes up the second act of the victory and in most cases is more important than the first† (Clausewitz 267). According to his view, he sees war as a nonlinear phenomenon that is naturally unpredictable through analytical means (Bayerchen 86). The second idea that Clausewitz gave was attacking the enemy’s centre of gravity. This was to be achieved by attacking the enemy’s army then followed by seizing his capital and attacking his alliances. The final idea is the â€Å"how to†, which is a concept of the culminating point. Clausewitz defines culminating point as strategic attacks that lead to the point where the remaining potency is just enough to sustain a cover an d wait for peace. Past that point then tables turn and the reaction follows with force that is usually a lot stronger compared to the original attack (Clausewitz 82). Difference between the two theorists There are a lot of differences between the two theorists and their ideas but with only one that can be considered over the others. Their difference mostly came in because: Clausewitz theories mainly dealt with how to win the war unlike Jomini’s which emphasized on teaching the leaders how to fight their battles. Conclusion Jomini’

Interview vs interrogation techniques Essay Example for Free

Interview vs interrogation techniques Essay While this may be an interrogation, the problem in this scenario is that it works under the assumption that Jacob is already guilty of the offense committed. It is the constitutional right of every person to be presumed innocent until proven guilty even if the person is caught in the act of committing a crime. By confronting the suspect or culprit, the police will not be able to elicit the information that is required. The questions that are being propounded by the police investigator do not allow Jacob the chance to answer the real questions which tend to deal with his commission of the offense. Being bombarded with such probing questions, in this case, the stacking questions will only serve to confuse Jacob and cause him to be defensive, thus nullifying any chance that the police will actually be able to get a confession from him. This is also an example of a loaded question which also serves to confuse Jacob. If I were the detective, I would ask open ended questions first to make the suspect feel at ease and allow him to answer the questions then ask closed ended questions that would help narrow down his interrogation to more specific items. This method works best in these situations because it adds a structure and a flow to the questioning and it leads to a desired outcome. Unlike the example in this scenario where there is no clear purpose as to the questioning. The detective should first determine the exact information that he wants to elicit from the suspect. Irrelevant questions such as the reaction of the parents should be avoided by the detective. The issue of motive should be approached differently instead of asking why the suspect committed a stupid act, the detective should instead take a neutral stance first and ask the suspect what exactly happened from his point of view then introduce evidence that may rebut his testimony to attempt to steer the suspect into telling the truth or even confessing.

Infinite Virtue :: William Shakespeare Antony Cleopatra Essays

Infinite Virtue IV.viii of Shakespeare's Antony and Cleopatra is a short scene, less than 40 lines, and an entirely unexpected one. The preceding scenes of Act IV, such as Hercules' departure and Enobarbus' desertion, heavily foreshadow Antony's defeat. When Antony wins his battle against Caesar and returns to Cleopatra in IV.viii, the joy of their reunion contrasts with the despair of Act IV. Antony's victory is a strike against fate and a tribute, albeit short-lived, to the power of Egypt. The association of royalty and divinity was a common tradition not limited to the Elizabethans' world picture. In this scene, Antony portrays Cleopatra as a goddess, revealing her connection not only to the macrocosm but also to the more specific functions of the love goddess Isis. Cleopatra is a "great fairy" (IV.viii.12), able to "bless" (IV.viii.13) soldiers with her speech. As the "day o'th'world" (IV.viii.13) who will "ride" (IV.viii.16) in Antony's heart, she more particularly resembles a sun deity, pictured by the Egyptians as riding in a barge and by the Romans as in a chariot. Cleopatra's association with the day continues up until her death; Charmian recognizes that "the bright day is done/and we are for the dark" (V.ii.192-3) and Cleopatra sees that her "lamp is spent" (IV.xv.89). In Act V, the connection is morbid, but here it is vibrant and positive. Yet in both death and life, the close relationship of Cleopatra and Egypt to fire and the higher elements is omnipresent; Antony swears "by the fire/that quickens Nilus' slime" (I.iii.69-70); Cleopatra before her death is "fire and air" (V.2.288); "your serpent of Egypt is bred...by the operation of your sun" (II.vii.26-7) That fire should so often be linked to life is unsurprising, given the common connection between heat and sex, just as the heart where Cleopatra will ride has long been a "bellows" (I.i.9). Also present is an idea of "vital heat", as when Cleopatra invites Iras to "take the last warmth" (V.ii.290) of her lips before her suicide. Whether fortunate or not, Cleopatra is a spirit of vitality. Even Antony gets a taste of residual divinity, perhaps from Cleopatra's having dressed him; he is "infinite virtue" (IV.viii.17) and "lord of lords" (IV.viii.16), echoing the prophecy that "the Lamb shall overcome [the ten kings], for he is Lord of lords and King of kings" (Revelation 17:14). In fighting for Egypt Antony momentarily wrests conquering fate from Octavius, whose statement that "the time of universal peace is near.

Heart Dissection Report Essay

Introduction/Purpose In this lab experiment, I examined a pig’s heart and compared it to a human’s heart. The pig’s heart is very similar to a human’s heart by having the same structures, veins, valves, and chambers. I was unable to perform hands on examination on a human heart so I examined a pig’s heart. I was able to identify major areas of the heart and dissect it to examine the inside chambers and valves. This experiment helped me have a better understanding of the heart and how it functions. Materials and Methods In order to dissect the heart, I used many different instruments. I used a dissecting tray, biohazard bag, a probe, forceps, scissors, and a scalpel. The procedure follows: 1) Rinse the heart to remove as much of the preservative as possible. 2) Locate and identify different areas of the outside of the heart. Identify the coronary artery, great cardiac vein, aorta, pulmonary trunk, superior vena cava, auricles, visceral pericardium, right and left atrium, and the right and left ventricles. 3) Use the probe to figure out where the vena cava, aorta, and pulmonary arteries enter or exit the heart. 4) Locate and dissect the great cardiac vein. Use the scalpel to slice on both sides of the great cardiac vein and across the top. Use the forceps to pull out the vein to examine it closer. 5) Use the scalpel to perform a frontal dissection on the heart. 6) Identify the right and left atrium, right and left ventricles, the tricuspid valve, the mitral valve, chordae tendineae, and the papillary muscles. 7) Use the scalpel or scissors to make a sagittal dissection of the heart. 8) Examine the tricuspid valve and mitral valve closer. 9) Dispose the heart into the biohazard bags. Rinse and clean the trays. Data and Results I was able to acquire a better understanding of how the heart functions by doing this lab. I was able to identify all of the structures, veins, arteries, valves and chambers. I was able to see how the left ventricle was a lot larger and thicker than the right ventricle. I also got a better understanding of how the blood flows through the heart and through the arteries and veins. Discussion or Analysis The pig’s heart was very similar to the human heart and made it easy to identify all of the structures. I was able to pull out the great cardiac vein and view how small it was. This is the vein that if it is clogged, you have a heart attack. Conclusion In conclusion, this experiment was a great learning tool to better understand the heart. I was able to hold the heart and look at it at many different angles to understand it better. The pig’s heart was similar to the human heart so it was almost like I was looking at the human heart.
