Union General William Tecumseh Shermans Carolina Campaign...

Union General William Tecumseh Sherman’s Carolina campaign during the American Civil War led to the capital of South Carolina in the city of Columbia in early 1865. Sherman was employing a new military strategy of total war, in which he considered the civilian population and their property as military targets. Upon hearing of Sherman’s march toward Columbia, the Confederate cavalry General Wade Hampton faced the reality that Columbia would be lost to Sherman. The question for Hampton was how to prepare for the invasion of Columbia with a focus on the disposition of supplies ranging from cotton, food, and alcohol, to military-related supplies such as ammunition, rifles, and cannons. It was both obvious and imperative to the Confederacy that the Union could not take possession of these supplies, since this would simultaneously help the Union and seriously hurt the Confederacy. Additionally, the presence of the cotton would make the potential of fire a real danger for the citizenry and the buildings in which they lived, worked, gathered, and prayed. Confederate General Wade Hampton unsuccessfully employed the tenants of the current U.S. Army mission command philosophy during the Union General Sherman’s campaign through South Carolina. Hampton’s failure to follow the yet to be written philosophy of mission command both before and during Sherman’s occupation of Columbia directly destroyed what little chance of winning the war the South may have clung to.

Before a response can be formulated, a discussion needs to be made. This involves whether to immediately pursue the attacker or protect the organization. Having a protocol in advance with management can establish priorities and expedite a decision. It is important to have a set of responses prepared in advance. Allowing the attacker to continue provides evidence on the attack. The most common response is to stop the attack as quickly as possible. Pg 309 How do you collect data?

Pg 61 Governance, Risk management, and Compliance (GRC) and Enterprise Risk Management (ERM) both to control risk. ERM takes a broad look at risk, while GRC is technology focused. GRC top three best frameworks are ISO 27000 series, COBIT, COSO. Pg 197 Incident severity classification: * Severity 4 – small number of system probes or scans detected. An isolated instance of a virus. Event handled by automated controls. No unauthorized activity detected. * Severity 3 – significant probes or scans. Widespread virus activity. Event requires manual intervention. No unauthorized activity detected. * Severity 2 – DOS detected with limited impact. automated controls failed to prevent event. No unauthorized activity detected. * Severity 1 – successful penetration or DOS attack with significant disruption. Or unauthorized activity detected. Pg 308 To measure the effectiveness include IRT charter goals and analytics. Metrics are: * Number of incidents * Number of repeat incidents (signifies lack of training) * Time to contain per incident (every incident is diff, least important) * Financial impact to the organization (most important to management) Glossary terms Bolt-on refers to adding information security as a distinct layer of control after the fact.

Great Gatsby Point of View Analysis Essay Example For Students

Great Gatsby Point of View Analysis Essay Outline1 The Main Peculiarities of Narration in the Great Gatsby2 Point of View in Fitzgerald’s Novel3 Nick Caraway as the Narrator4 Conclusion The Main Peculiarities of Narration in the Great Gatsby It is apparent that the point of view plays an important role in any novel as it influences the way readers understand and interpret the whole story. Point of view is usually expressed through a certain type of narration. A narrator in the novel is the one who tells the story, and it is defined by how the author chooses to portray information and opinions. Sometimes, the narrator provides insight into how the author views events and characters and reveals his/her personal opinions. In other cases, the narrator remains unprejudiced and does not provide any evaluations or visions. In The Great Gatsby, the narrator is Nick Caraway, one of the main characters of the story, who is present at almost every major event throughout the novel. Fitzgerald makes him a peripheral first-person narrator, and such a choice is not accidental. The matter is that even though Caraway is an important figure in the novel, he does not show his personal opinions and feelings vividly. As a result, in the story, he seems to be partially removed. Point of View in Fitzgerald’s Novel The readers see all the events through the prism of Caraway’s vision, and his point of view influences the readers’ interpretation of events. Such a technique is extremely effective in case of Great Gatsby’s tale because it helps to keep the readers in suspense from the beginning to the end. The matter is that the narrator is ignorant of any events and thoughts beyond what is told to him, and it makes the readers intrigued. Point of view is essential in The Great Gatsby. Although the readers perceive the events through the vision of Nick Caraway, the author does not impose his personal opinions on readers. Fitzgerald ensures that his character gives nothing away. As a result, the readers have to make conclusions themselves. Due to such a technique, the novel is very effective in entertaining readers and keeping them interested throughout the whole story. The manner of narration leaves the readers curious about what the characters of the story think and feel and gives an opportunity to make own conclusions and interpret the text differently. For example, at the end of the novel, the author tells about one gentleman’s statement concerning Gatsby’s death. This gentleman told that Gatsby got what he deserved. This statement makes readers think of how they feel about his death, whether they agree with the gentleman or pity Gatsby. Nick Caraway as the Narrator In The Great Gatsby, the character of Nick Caraway can be viewed as a kind of vehicle used to gather information about Gatsby. His character is particularly effective in describing all the â€Å"true colors† of Gatsby and his actions comprehensively. The matter is that he is a narrator and an innocent bystander simultaneously. At the same time, besides being extremely important for revealing the events in the novel, Nick Caraway is also a unique personality. He is different from all the other characters, who are primarily reckless people who do not care about others. Because of the fact that Nick’s values and behavior differ from his friends’ life principles and actions, he is an outsider in this society. Nevertheless, he is present at all most important events and turning points in the story. He witnesses the key scenes that help tell the readers everything about Gatsby from his point of view. .u8824e56c6ca4c9430bedaf64cba73f45 , .u8824e56c6ca4c9430bedaf64cba73f45 .postImageUrl , .u8824e56c6ca4c9430bedaf64cba73f45 .centered-text-area { min-height: 80px; position: relative; } .u8824e56c6ca4c9430bedaf64cba73f45 , .u8824e56c6ca4c9430bedaf64cba73f45:hover , .u8824e56c6ca4c9430bedaf64cba73f45:visited , .u8824e56c6ca4c9430bedaf64cba73f45:active { border:0!important; } .u8824e56c6ca4c9430bedaf64cba73f45 .clearfix:after { content: ""; display: table; clear: both; } .u8824e56c6ca4c9430bedaf64cba73f45 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u8824e56c6ca4c9430bedaf64cba73f45:active , .u8824e56c6ca4c9430bedaf64cba73f45:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u8824e56c6ca4c9430bedaf64cba73f45 .centered-text-area { width: 100%; position: relative ; } .u8824e56c6ca4c9430bedaf64cba73f45 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u8824e56c6ca4c9430bedaf64cba73f45 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u8824e56c6ca4c9430bedaf64cba73f45 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u8824e56c6ca4c9430bedaf64cba73f45:hover .ctaButton { background-color: #34495E!important; } .u8824e56c6ca4c9430bedaf64cba73f45 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u8824e56c6ca4c9430bedaf64cba73f45 .u8824e56c6ca4c9430bedaf64cba73f45-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u8824e56c6ca4c9430bedaf64cba73f45:after { content: ""; display: block; clear: both; } READ: The quiet american EssayNick is shown as an ever-present yet aloof narrator who describes everything in a logical and cool manner. He does not judge other people or impose his thoughts and values on readers. For example, he does not judge Gatsby for his immoral principles and actions. At the same time, he provides important details concerning the settings in which the key events occur as well as some general information and background regarding other characters. Being a present yet rather distanced narrator, Nick ensures that the readers have freedom in choosing their attitudes and forming personal opinions about characters and events. For instance, one of the most importa nt descriptions given by Nick Caraway is presented in an episode where Tom Buchanan hits Myrtle at the Manhattan apartment. He tells the readers what happens and remains logical and cool about what he witnesses. Finally, he simply leaves the apartment, and it emphasizes once more Nick’s being an aloof character. He is able to distance himself and his feelings from what is happening to give the readers an objective picture. Such a unique character as Nick Caraway makes the novel special and effective. As a narrator, he is aloof and ignorant of other characters’ hidden thoughts or motives. As a result, a reader is able to comprehend the events together with him Conclusion In his novel, Fitzgerald uses a specific type of narration. A narrator is a character of the story, Nick Caraway. He is an ever-present yet distant character, and he reveals all the important information about other characters to readers. Due to the fact that he does not reveal his personal opinions and doe not judge others, the readers are able to interpret the text according to their personal thoughts. As a result, the novel is intriguing and keeps readers in suspense from the beginning to the end. Point of view plays an extremely important role in Fitzgerald’s novel as the readers see the events from the narrators point of view. At the same time, Fitzgerald makes it possible for readers to develop personal points of view as the narrator remains unprejudiced and logical in his descriptions. In other words, readers are able to view each character from an objective and comprehensive perspective. At the same time, what is particularly significant is that the narrator is ignorant of the hidden subtexts and motives of actions as well as of other characters feelings and thoughts. It makes readers believe him and stay curious developing own assumptions.

Endocrine Lab Report Sample

Endocrine Lab Report Paper Smooth muscles are typically under control of the autonomic nervous system, and do not contract voluntarily. Smooth muscle contracts slowly, and does not exhibit the characteristic twitch seen in skeletal muscle. In addition, smooth muscle is not prone to muscle fatigue, making it an ideal component of sphincter muscles. Smooth muscle is found in the gastrointestinal tract of many animals, and is responsible for peristaltic movements. Smooth muscle is also present in the walls of arteries and arterioles, where it helps to regulate blood pressure and flow. Smooth muscle contractions are affected by calcium and potassium ions. Calcium ion influx into the smooth muscle cell initiates a contraction. Potassium ion concentration in the extracurricular medium affects the resting membrane potential of the cell, bringing it closer to or farther away from its threshold voltage. Neurotransmitters affect different types of smooth muscle differently, depending on the association of the smooth muscle with excitable cells. In general, acetylenes increases the muscle cells permeability to calcium, while epinephrine decreases the cells permeability to calcium. The earthworm (Limericks SSP. ) gut can be dissected and examined in vitro sing an organ bath and force transducer. This preparation is robust; it can remain active for several hours. In this experiment, you will measure the rate and force of contractions in the in vitro earthworm gut, and examine its response to changes in extracurricular ion concentration and to the presence of neurotransmitters.

A new blank data file will open after a few moments. This file should have one channel, labeled Force. 7. Click the Force channel function pop-up menu and select Bridge Pod. The Bridge Pod dialog box will open. 8. Observe the signal in the dialog box. Zero this signal by turning the knob on the front of the Bridge Pod (figure). If you cannot zero the Bridge Pod, contact your instructor for assistance. B. Earthworm dissection Refer to the diagrams in your earthworm dissection guide for assistance. Anesthetizing 1. Fill a fingernail halfway with 15% ethanol. 2. Obtain a large earthworm and rinse it under tap water to remove excess dirt. 3. Place the earthworm in the fingernail for five minutes; the earthworm should stop moving. Dissection: exposing the gut 1 . Remove the earthworm from the ethanol and place it on a dissection tray. 2. Pin the earthworm to the tray using one pin on either end of the worm. 3. Moisten the earthworm with room temperature earthworm saline. You must keep the worm moist at all times during the dissection. Locate the cellulite (copulation organ); this structure is closest to the anterior of the earthworm. 5. Using fine pointed scissors, carefully make a shallow incision in the cellulite. Make this incision to the side of the midlines; this techniques will prevent you from cutting into the gut. NOTE: It is essential not to cut deeply during the dissection; you will damage the gut t issue. If you tear the gut, obtain another earthworm and start over. 6. Continue cutting the skin of the earthworm towards the anterior end. It is best to use an upward-pointing direction with the scissors. As you cut the skin, in back the skin to expose the gut. 7. When you have successfully opened the earthworm, inspect the gut and moisten the worm with earthworm saline. If the gut is not damaged, continue with the next step. Dissection: removing the gut 1 . With the gut exposed, use a blunt probe to dissect away the septa that connect the underside of the gut to the body wall. You only need to expose 3-5 CM of the anterior gut. 2. When the gut is loosened from the body wall, again check to make sure it is not torn. 3. Tie a 20 CM piece of strong thread to the gut anterior to the pharynx and another piece 3-5 CM posterior to the pharynx. You should have 10-15 CM of loose thread available after you tie off the gut so that you can attach the gut to the organ bath and force transducer. 4. Using scissors, carefully remove the gut section from the earthworm. Mounting the gut in the organ bath 1 . Tie the posterior end of the earthworm gut to the mounting hook and mount the hook on the ring stand so the gut is in the organ bath. The distal end of the intestine should be 1 CM from the glass hook. Be sure to hold on to the thread on the anterior end. 2. Lower the force transducer on the microdensitometer its lowest position. 3. Tie the thread on the anterior end of the gut (pharynx end) to the force transducer. The gut should be slack. 4. Carefully raise the micrometeorites by turning the adjustment knob until the gut is under slight tension. NOTE: Be extremely careful not to overstretch the gut during this step. The gut is very delicate and could tear easily. 5. Make sure the drain stopcock on the organ bath is closed. Fill the organ bath with normal earthworm saline. The gut should now be completely submerged. If the gut is not completely submerged, you may need to re-tie the lower thread to the hook. [pica] Figure 1.

Executive Decision Making Essay Example | Topics and Well Written Essays - 6000 words

Executive Decision Making - Essay Example   It would be necessary before constructing a contract to determine whether the supplier will want such advances and then weigh this against operational costs of the business model. Furthermore, if the agreement between the supplier and the distributor is not going to be long-lived, contracts may ask for some variety of reimbursement related to the tooling costs to meet the distributor’s demand. This could be non-beneficial for a smaller organization that might be struggling to achieve profit. Any and all expenses must be considered before seeking foreign sourcing opportunities. If the supplier is chosen will be a partner for a multi-year relationship, then issues of potential pricing must be weighed before making this decision. Costs of manufacturing are influenced by changing labor wage rates and fluctuating prices of raw materials in the global supply chain. It can be difficult to establish an appropriate pricing agreement under a long duration contract as it is not easy to predict what costs will be incurred in the future. The vendor could, in the future, demand a higher price (which can be rejected by the distributor) which could terminate the contract. This would have disadvantages as it takes time for supplier partners to understand the needs of their client and alter manufacturing to fit distributor needs. Hence, in a price dispute, it could lead to further costs in identifying an alternative supplier. Additionally, product liability is a major concern for companies seeking overseas sourcing. There is a substantial risk that consumers purchasing products made in a foreign nation could have personal injuries as a result of using the foreign-made product or property damage if the product happens to be.

Reading with Awareness Essay Example | Topics and Well Written Essays - 750 words

Reading with Awareness - Essay Example As a freshman, I was afraid that this would prove to be an insurmountable obstacle in my pursuit of academic excellence. However, I have been very fortunate in overcoming this handicap, and making great strides in improving my command of the English language, in quite a short period of time. Of course, I have put in a lot of hard work, and can take credit for being an A student. But this would never have been possible without the strengthening of my English comprehension and writing skills. I am deeply aware that my success is in large part due to my enrollment in the Introduction to College Level Reading and Writing course. The factors which facilitated my improvement are the gradual progression from simple texts to more complex ones, the application of critical thinking, the adoption of thesis-based writing techniques, and the awareness of my learning processes. The gradual progression from simple texts to more complex ones has been a great facilitator in my path to the mastery of the English language, particularly in my writing of the essay, â€Å"The Stories Can Save Us†. If I had been plunged into a complex essay, such as Heroes, in the very beginning, I would definitely have been tempted to throw up my hands! My confidence would have been eroded, and it would have made the course very stressful. Beginning with the simpler essays, such as the Advertisement, was a great way to gradually lead me into deeper waters. This gave me the breathing space to consolidate the gains I have made in English, to gradually add to my vocabulary, and to take time to absorb the significance of my reading material. What is even more important to me, this gradual progression has helped me to learn to enjoy English writing, without it becoming a tedious classroom chore. The application of critical thinking to my reading followed from my growing confidence. What at first appeared to be just straightforward stories, changed contour with repeated reading. I have learned not to take any writing at face value: just as the story of The Emperor’s New Clothes cautions people to think for themselves. My instructor’s guidance has made me understand that there are several messages the writer conveys through a story, and an in-depth study is necessary to make these messages evident. I have learnt to ask questions regarding what the author is trying to say, the motives behind the writing, different shades of meaning, the importance of things left unsaid, and the use of different writing techniques to achieve the desired effect in a story. In short, I have learnt to ask the question, â€Å"Why?† when I read. This has made my reading a much richer experience than it was before I started this course. The adoption of thesis-based writing techniques has been a major gain for me. Earlier, I have been accustomed to putting down my thoughts on paper, as and how these occurred to me. Writing within the framework of a thesis has given my essays and re search papers a clarity that has lifted them to the next level. I continue to be amazed at the difference that can be made by adhering to the simple structure of an introductory paragraph with a clear thesis, body paragraphs, and the conclusion. This structure has given coherence to my writing, helped me to write logically, and taught me how to build up and substantiate my point of view. This was my main strength in writing the essay, â€Å"The Stories Can Save Us†. I must acknowledge that the awareness of my learning process was made possible only through my continuous interaction with my instructor. Although I was conscious, in a very general way, of the great improvement I was making

Ethical Issues Inherent with Workplace Stress Term Paper

Ethical Issues Inherent with Workplace Stress - Term Paper Example Solutions for each problem are also mentioned with short implementation strategies. Conclusions are drawn at the end of the paper. Ethical Issues Inherent with Workplace Stress Introduction Due to the rapid changes in the market and industry the levels of stress at workplace are increasing every day and the staff and workers are being pushed hard to meet the targets. Stress has now become part and parcel of the life of each and every individual regardless of the profession. Constantly changing deadlines, long working hours, assignments beyond the capacity of workers are a few issues that the employees have to deal with at workplace. In addition to these most of the time the employees and staff members do not get the expected recognition and encouragement from the authorities. Some of the employees do not get the required health care options and their firms do not offer any stress management programs. Some individuals despite working very hard do not get the opportunity to grow in the organization and achieve higher positions, this adds to the stress they are carrying. The working environment is another important factor in determining the levels of workplace stress in individuals and workplace harassment is a major cause of stress in some organizations. Conflicts between colleagues are very likely to occur in a stressed working environment resulting in more stress. ... Ethics in a society depends upon the feelings of the individuals that form the society. Therefore the workplace ethics of a particular company or firm depend upon the society, the workplace environment, the cultural aspects of the region of company’s existence or the region in which the company does business and also on the organizational structure and employees’ development in a company. The Ethical Issues The various issues that can be classified as ethical issues inherent with workplace stress are: 1. Lack of encouragement and recognition 2. Insufficient health care facilities and lack of stress management programs for the employees 3. Conflicts between colleagues over work distribution and allocation 4. Harassment at workplace 5. Immoral workplace practices These issues will be discussed in detail in the following pages. Lack of Encouragement and Recognition This is the most common cause of workplace stress. It is the moral as well as professional responsibility of the employer to encourage, recognize and reward his employees for their efforts. Recognition is very important and serves as the motivational force which increases the productivity and efficiency of employees and at the same time it makes them own the company. When the employees are recognized and rewarded for their efforts through promotions, salary increments and performance certificates, a sense of growth is felt by the employees. As a result they work more enthusiastically because they start deeming the progress of company as their own progress. On the other hand if employees are not recognized and rewarded for their efforts this greatly affects their performance because when an employee gets a

Study On Use Of Pile Foundation Engineering Essay

Study On Use Of Pile Foundation Engineering Essay Piles and pile foundations have been in use since prehistoric times. Pile is commonly described as a columnar element of a building foundation. Its function is to transfer the load from a superstructure to the hard layer in the soil, or on to the rocks. The objective of this project is to identify piles and its uses in the construction industry, based on its types and suitability. This report is based on the three main types of piles, which are large displacement piles, small displacement piles and replacement piles. Figure 1. Pile Construction This report also contains research materials done by several authors have published various journals on the aforementioned topic, and numerous engineering books on pile, pile engineering, soil types, etc have been referred to assist this report. Many journals were consulted during the inception of this research. Topics like Efficiency of Pile groups installed in cohensionless soil using artificial neural networks, Experimental study on pile-end post-grouting piles for super large bridge pile foundations, etc were consulted. From these journals, it has been concluded an Artificial Intelligence application can be made to predict the efficiency of the pile. Based on the results, a pile cap can be created, or even grouting works can be performed to improve the load bearing of the structure. The commonest function of piles is to transfer a load that cannot be adequately supported at shallow depths to a depth where adequate support becomes available, also against uplift forces which cause cracks and other damages on superstructure. A bearing pile is described as a pile which can pass through weak material, whilst its tip get across a narrow distance, which in turn leads to a layer of improved bearing capacity. When piles are installed onto a layer with minimal ability to support, and the bearing capacity is being carried by friction which is acting on the sides of the pile, they are called friction piles. Many times, the load-carrying capacity of piles results from a combination of point resistance and skin friction. The load taken by a single pile can be determined by a static load test. The allowable load is obtained by applying a factor of safety to the failure load. Types of Piles Piles are of various types. These piles are classified based on the scope of construction and soil type. Figure 3. Common Driven Pile Types Concrete Piles Precast concrete piles can be either reinforced concrete piles or prestressed concrete piles. Concrete is adaptable for a wide range of pile types. It can be used in precast form in driven piles, or as insertion units in bore piles. Dense well-compacted good- quality concrete can withstand fairly hard driving and it is resistant to attack by aggressive substances in the soil, or in seawater or ground water. However, concrete is precast piles is liable to damage (possibly unseen) in hard driving conditions. Weak, honeycombed concrete in cast-in-situ piles is liable to disintegration when aggressive substances are precast in soils or in ground water. Cast In Place Concrete Piles Closed-ended hollow tubular sections of reinforced concrete or steel which are first driven into the ground and then filled with in-situ concrete. Cast-in-place concrete piles with their shell driven with mandrel are typically 50 to 80 ft (15 to 24 m) long and can specifically be designed for a wide range of loads. Typical loads that these piles can carry are 50 to 120 kips (222 to 534 kN) provided the maximum stress in concrete, is not more than 33% of 28-day strength. Figure 4. Cast-in-Situ Concrete Piles The main disadvantages are that these piles are difficult to splice after concreting, their thin shells can be damaged during driving, and redriving is not recommended. Not the most economical solution, limited span length and requires formwork support. Generally, stress in steel should not exceed 0.35 x yield strength of steel. Figure 5. Cast-in-Situ Concrete Piles The advantages are tht they have low initial cost, and tapered sections can provide higher-bearing resistance in granular stratum. These piles are best suited as medium-load friction piles in granular soils. Absolute minimum depth, no deck joints and aesthetic for small stream crossings. Precast Concrete Piles Manufacturing of pre-cast concrete piles are done within the range of 250mm 450mm. Mostly, the maximum section length can go up to 20m. There are various shapes of pile sections (eg. H-shaped, triangular-shaped, hexagonal-shaped, etc). Figure 6. Precast Reinforced Concrete Pile The construction of pre-cast concrete piles are done either in-situ or factory. Production and construction process widely affects the quality of the pile. A pile shoe should be fixed to the pile, in case the soil deposits contain a lot of boulders. This protects the pile while performing hard driving. For prestressed sections the maximum stresses should not exceed (0.33Æ’c 0.27 pe); where pe = effective prestress stress on the section. The main disadvantages of these piles are that they are difficult to handle without damage unless prestressed. They have a high initial cost, and prestressed piles are difficult to splice. It is also difficult to manufacture, subject to longitudinal and transverse cracking, not appropriate for curved or flared structures, complicated for skews. The advantages of these pile types include high load capacities, corrosion resistance, and resistance to hard driving. Absolute minimum depth of precast bridge for short and intermediate spans. Expedites stage construction. Drilled Shafts Drilled shafts are also known as caissons or piers or bored piles. This is often known to be a cost effective solution which is practiced worldwide. This is a widely used type of deep-foundation. Drilled Shafts are widely used in the construction of bridges and large buildings. This technique is used in construction areas where large loads along with lateral resistance are key factors. Figure 7.1. Drilled Shaft The main advantages are that it is economical, it could minimize pile need for pile cap, slightly less noise and reduced vibrations, adapts easily to varying site conditions and has high axial and lateral loading capacity. The main disadvantages are that it is extremely sensitive to construction procedures, not ideal for contaminated sites, and lack of qualified inspectors. Figure 7.2. Drilled Shaft A Drilled Pile is made of concrete or grout and cast or poured, in a plastic state, into a drilled hole in the earth. Augercast, Drilled Shafts, Drilled Cast-in-situ and, their variations are all forms of drilled piles. Completed drilled piles cannot be easily inspected after installation and can be difficult to install in very soft or loose soils, wet, and marine conditions. A Drilled Pile removes soil from the ground and the resulting round hole is filled with concrete or grout. Steel Piles These are more expensive then timber or concrete but this disadvantage may be outweighed by the ease of handling of steel piles, by their ability to withstand hard driving, by their resilience and strength in bending, and their capability to carry heavy loads. Steel piles can be driven in very long lengths and cause little ground displacement. They are liable to corrosion above the soil line and in disturbed ground, and they require cathodic protection of a tong life is desired in marine structures. Long steel piles of slender section may suffer damage by buckling if they deviate from their true alignment during driving. Figure 8. Steel Piles Steel piles are strong, lightweight to handle, and capable ofcarrying heavy loads to deeper bearing stratum. They can be extended to any length since splicing is relatively easy, and these can also be readily cut to any required length. This makes steel piles suitable for areas where the depth of bearing strata are variable. Various types of steel piles in common use include pipe piles, H-section piles, box section piles, and tapered and fluted tubes. Pipe piles and H-section piles are the most commonly used steel piles in engineering practice. Steel pipe piles can either be driven open ended or closed ended. Open-ended piles will experience less driving resistance and can be drilled through obstructions such as boulders and bedrock. The piles are generally economical in the range of 40 to 80 ft (12 to 24 m) and can carry loads as high as about 250 kips (1115 kN). Pipe piles are most suited where overburden is soft clays, silts, and loose-to-medium dense sand and is underlain by dense-bearing granular material. H-Piles A form of Steel pile is known as H-Pile. These are wide-flanged sections made of steel. The biggest advantage of this pile is that the displacement of soil becomes very less, when compared against other soil displacement methods practiced in the world. The H-pile falls under small displacement category. Figure 9. H-Piles Timber piles cannot be driven through hard ground. Steel H-piles are essentially end-bearing piles. Due to limited perimeter area, H-piles cannot generate much frictional resistance. Corrosion is a major problem for steel H-piles. The corrosion is controlled by adding copper into steel. H-piles are easily spliced. They are ideal for highly variable soil conditions. H-piles can bend under very hard ground conditions. This is known as dog legging, and the pile installation supervisor needs to make sure that the piles are not out of plumb. H-piles can get plugged during the driving process. If the H-pile is plugged, end bearing may increase due to larger area. On the other hand, skin frictionmay become smaller due to smaller wall area. When H-piles are driven, both analyses should be done (unplugged and plugged) and the lower value should be used for design. Unplugged: Low end bearing, high skin friction. Plugged: Low skin friction, high end bearing. Advantages are that H-pile is available in various lengths and sizes easy to splice high capacity low soil displacement many penetrate larger obstructions with driving shoes. The disadvantages are that it is vulnerable to corrosion, hence not recommended as friction piles in granular soils may force the h-pile to bend on the weaker axis, during the pile-driving process. Due to this, there is a high chance of curvature, which may result when the piles are driven into a larger depth. Cylindrical Cylindrical piles have a high axial compressive strength for high bearing capacities; they have high moments of inertia and therefore can serve well as both a column and a foundation pile under high vertical and lateral loads. Figure 10. Cylinder Piles Cylinder piles are often used in nearshore applications where smaller foundation piles would require cofferdam construction and other costly measures. Drilled shafts have similar load bearing properties and capabilities, however, they are generally more costly than piles installed by impact driving. Timber Piles Untreated timber piles may be used for temporary construction, revetments, fenders and similar work; and in permanent construction where the cutoff elevation of the pile is below the permanent ground water table and where the piles are not exposed to marine borers. They are also sometimes used for trestle construction, although treated piles are preferred. Timber piles are difficult to extend, hard to anchor into the footing to resist uplift, and subject to damage if not driven carefully. Timber piles also have a maximum allowable bearing capacity of 45 Tons, whereas most structure piles are designed for at least 70 Tons. These piles are mostly installed by driving and are best suited as friction piles in granular material. Figure 11. Timber Piles The main advantages of timber piles are that they have low initial cost, are easy to handle, and resist decay when they are permanently submerged. The main disadvantages are that it is tough to splice, are vulnerable to damage in hard driving, and are susceptible to decay unless treated. Treatment becomes necessary when these piles are intermittently submerged. Composite Piles Materials may be used in combination in piles and the most common example is the use of steel and concrete. This may be by using driven steel casings of various types filled with a structural core of concrete, or a steel pile protected externally by concrete casing; the latter is normally only possible for exposed lengths of piles such as would be encountered in a jetty structure. There are, however, forms of steel pile, which have grout pipes throughout their length, which are used for forming a protective outer casing after driving. Figure 12. Composite Piles The maximum stresses in timber, steel and concrete should not exceed the values specified above for various materials. The main disadvantage of these piles is that it is difficult to attain good joint between two materials. The main advantage is that considerable length can be provided at comparatively low cost. High capacity may be possible depending on materials. use of piles in construction There are two types of piles used for construction: Displacement Piles Non-Displacement Piles DisplacemeNt Pile The type of pile, which is rammed into the ground, which does not remove the soil, but displaces the soil downwards and sidewise. This type of pile foundation is called displacement pile. Figure 13. Displacement Piles This method piles displace soil during their installation, such as driving, jacking, or vibration, into the ground. Examples of these types of piles are timber, precast concrete, prestressed concrete, close-ended steel pipe, and fluted and tapered steel tube piles. The advantages of displacement piles are: Material forming pile can be inspected for quality. Soundness before driving. Not liable to squeezing or necking. Construction operation not affected by ground water. Projection above ground level advantageous to marine structures. Can be driven in the very long lengths. The disadvantages of displacement piles are: May break during driving, necessitation replacement pile. Unseen damages may occurring thus decreasing the carrying capacity. Noise pollution may be caused during hammering. Vibration caused during the hammering process may pose a threat to nearby structures. Non-DisplacemeNt Pile These Piles do not displace soil during their installation. These piles are formed by first removing the soil by boring and then placing prefabricated or cast-in-place pile into the hole from which an equal volume of soil was removed. Their placement causes little or no change in lateral ground stress, and, consequently, such piles develop less shaft friction than displacement piles of the same size and shape. Piling operation is done by such methods, as augering (drilling, rotary boring) or by grabbing (percussion boring). Most common types of no displacement piles are bored and cast-in-place concrete piles. The advantages of non displacement piles are: Material forming pile is not governed by handling or driving stresses. Can be installed in very long lengths. No ground heaves. Can be installed in conditions of low headroom. Figure 14. Non Displacement Piles The disadvantages of non displacement piles are: Concreting in water-bearing soils require special techniques. Inspection of concrete cannot be done after installation. Cannot be extended above ground level without special adoption. LITERATURE REVIEW Description of Journals This section contains the description paragraph for the 5 technical journals which has been chosen to support the main topic of research. Adel M. Hanna, George Morcous, and Mary Helmy (2004) Efficiency of Pile Groups Installed in Cohensionless Soil Using Artificial Neural Networks. Adel M.Hanna, George Morcous and Mary Helmy evaluated the efficiency of pile groups installed in cohension-less soil subjected to axial loading. The authors feel that a resistance to the column load may result in a major difference between the total capacity of the individual piles and the group piles. This could lead to destruction of the building. The authors have developed an ANN (Artificial Neural Network) model to assist the research. They have found that the ANN model is nearly 80% accurate to the predicted value. The predictions are very accurate, even with low tolerance values. They have also made an ANN model which can be easily updated when new data are obtained from laboratory and field tests. Kevin J.Bentley and M.Hesham El Naggar (2000). Numerical Analysis of Kinematic Response of Single Piles Kevin and Hesham have done a research on single piles, after anticipating the catastrophic losses in terms of human life and economic assets due to the earthquakes. They wanted to develop a model which evaluates the effects of ground motion on piles. Their aim was to develop a finite element model that can accurately model the kinematic soil-structure interaction of piles, accounting for non linear behavior of soil, discontinuity at the pile soil interface, energy dissipation and wave propagation. They found that the effect of the response of piles in elastic soil was slightly amplified in terms of accelerations and Fourier amplitudes. The authors have taken a good amount of information from previous researches made. They have found that the previous studies had its own drawbacks, which were concluded that interaction effects on kinematic loading are not significant at low frequencies but are significant for pile head loading. The authors used finite element program, ANSYS to analyze the full 3D transient method. They have found that the deflections obtained in the study were slightly greater than those from other tests. The authors concluded that the effect of soil layer overlaying the bedrock was to amplify the bedrock motion, which results in a higher free-field motion for the soil parameters used in the analysis. Increased Fourier amplitudes at the predominant frequency was an effect of soil plasticity. It slightly decreased the maximum acceleration amplitudes. Jinoh Won and Fred H. Kulhawy (2009) Reduction of Pile Head Displacement for Restrained Head Single Pile. The authors conducted a study on the effect of pile head fixity on the displacement of laterally loaded pile groups using analytical methods. It was found that the soil parameters have a major influence on the reduction factor, while the pile property influence is relatively minor. The rationale behind the problem is described as most pile foundations have pile cap that reduces the lateral displacement because of restraining effect on the pile heads. The authors learned that the previous researches which were done were for small-scale tests only. The authors have performed numerous tests, from which they found that there is a variation of reduction factor with soil properties for the drained cohensionless model. The authors have done a quantitative analysis to investigate the effect of pile head restraint on the displacement using an analytical method. Their design chart is matched reasonably well with the experimental and numerical data. Ling-gang Kong and Li-min Zhang (2007). Effect of Pile-cap Connection on Behaviour of Torsionally Loaded Pile Groups Evaluation of the responses, under torsion, of fixed as well as pinned pile cap was done by the authors. They have researched that, the torsional capacity of the pile group is significantly influenced by the pile-cap. The same applies with the pile-groups torque assignment. The authors claim that grouped piles are usually used as foundations for offshore platform, bridge bents and tall buildings. Due to natural disturbances like wind and wave actions, ship impacts or high-speed vehicles, the grouped piles may be exposed to significant torsional loads, leading to destruction and catastrophic effects on them. The authors have found that the lateral ad torsional resistance of the individual piles is mobilized by a pile group which is subjected to torsion. This could thrust up to 50% of the applied force, whilst the pile-cap foundation is fixed. From the research it has been noted that under loose sand the pile bend a minimal degree. Whereas under dense sand, and the same load, the pile bend less than the loose sand. They have modeled nonlinear soil response and major pile-soil-pile interactions and coupling effect in a pile group. Weiming Gong, Guoliang Dai and Haowen Zhang (2009) Experimental Study on pile-end post-grouting piles for super-large bridge pile foundations. The authors made an experimental study on pile-end and post-grouting piles for very large bridge-pile foundations. Before the after-grouting works were evaluated, the authors wanted to analyze the bearing capacity, bearing characteristics and displacement. The authors introduced 21 test piles to perform the experiment. The technique was implemented to increase the capacity as well as decrease settlement. The author has done a lot of background researches, across various bridges. From the research it has been found that the capacities are greatly enhanced after pile-base grouting. The Q-s curve before grouting decrease sharply under small loads and have great deviations from existed geological values, which attributes to long term interval between drilling and grouting. So the authors have proved that, by grouting, they have steadily increase the bearing capacity of a bridge.

Addition of Introductory and Concluding Sentences Pile is commonly described as a columnar element of a building foundation. Its function is to transfer the load from a superstructure to the hard layer in the soil, or on to the rocks. Kevin and Hesham have done a research on single piles, after anticipating the catastrophic losses in terms of human life and economic assets due to the earthquakes. They wanted to develop a model which evaluates the effects of ground motion on piles. Their aim was to develop a finite element model that can accurately model the kinematic soil-structure interaction of piles, accounting for non linear behavior of soil, discontinuity at the pile soil interface, energy dissipation and wave propagation. They found that the effect of the response of piles in elastic soil was slightly amplified in terms of accelerations and Fourier amplitudes.

Increased Fourier amplitudes at the predominant frequency was an effect of soil plasticity. It slightly decreased the maximum acceleration amplitudes. The type of soil is an important entity while fixing piles. The authors conducted a study on the effect of pile head fixity on the displacement of laterally loaded pile groups using analytical methods. It was found that the soil parameters have a major influence on the reduction factor, while the pile property influence is relatively minor. The rationale behind the problem is described as most pile foundations have pile cap that reduces the lateral displacement because of restraining effect on the pile heads.

The authors have done a quantitative analysis to investigate the effect of pile head restraint on the displacement using an analytical method. Their design chart is matched reasonably well with the experimental and nu merical data. The frictional resistance of the pile is directly proportional to the soil cohesiveness, which means if the soil is cohesive, it will have a better contact with the area of the side pile. The pile cap distributes the load from the pillars, or piers, to the piles. The authors studied the reaction of the two pile caps (fixed and pinned) cap under torsion. They have researched that, the torsional capacity of the pile group is significantly influenced by the pile-cap. The same applies with the pile-groups torque assignment. The authors claim that grouped piles are usually used as foundations for offshore platform, bridge bents and tall buildings. Due to natural disturbances like wind and wave actions, ship impacts or high-speed vehicles, the grouped piles may be exposed to significant torsional loads, leading to destruction and catastrophic effects on them. The authors have found that a pile group subjected to torsion simultaneously mobilizes lateral and torsional resistance of the individual piles and the torsional resistance could thrust up to 50% of the applied force, whilst the pile-cap foundation is fixed. From the research it has been noted that under loose sand the pile bend a minimal degree. Where as under dense sand, and the same load, the pile bend less than the loose sand. They have modeled nonlinear soil response and major pile-soil-pile interactions and coupling effect in a pile group. An Artificial Intelligence based application need to be created which would perform tests based on experimental values. Adel M.Hanna, George Morcous and Mary Helmy evaluated the efficiency of pile groups installed in cohension-less soil subjected to axial loading. The authors feel that a resistance to the column load may result in a major difference between the total capacity of the individual

Free Hamlet Essays - Hamlet as a Love Story :: GCSE English Literature Coursework

Hamlet as a Love Story    The part of Hamlet that I would like to discuss is the love story theme. I think that it is very romantic how even in today's society we do not view the other aspects of Hamlet like revenge, delay, and madness but view Hamlet as a love story. I like the part of the love story when Hamlet writes that letter to Ophelia. The poem that Hamlet wrote to Ophelia, "'Doubt thou the stars are fire, doubt that the sun doth move; Doubt truth to be a liar; But never doubt our love."' I really like this quote because it is very romantic. -Marka Jones The aspect of Hamlet that I find interesting is the appearance of the ghost that Hamlet suspects may be the ghost of his father. Hamlet does not know if the ghost is actually of his father or if it is a demon taking on his father's appearance. How will he know what decision to make if he does not know what the ghost actually is? Also, now I'm wondering if Hamlet makes the wrong decision, will his decision lead to his death? This is the second play of Shakespeare's that I have read that has the appearance of ghosts. Macbeth also had apparitions appear in it. Shakespeare seems to have a method of placing ghosts into his writings, and in Macbeth these ghosts led to the downfall of Macbeth. -Keisha McWhorter "Something is rotten in the state of Denmark." "antic disposition." Hamlet states this after he discovers Claudius killed his father. If indeed Hamlet was mad, the fact that Claudius killed his father could have been a cause; however it seems that by the second quote he decided to pretend he is crazy. I do not think that the death of his father drove him mad. -Matthew Kilgore Act 1, Scene 2, Line 66 KING. How is it that the clouds still hang on you? HAM. Not so, my lord. I am too much in the sun. QUEEN. Good Hamlet. Cast thy nighted color off, And let thine eye look like a friend on Denmark. Do not for ever with thy vailed lids Seek for thy noble father in the dust. Thou know'st 'tis common - all that lives must die, Passing through nature to eternity. In the above conversation the Queen and the King both feel Hamlet meant what he said.
