Effective support for information users Coursework

Effective support for information users - Coursework Example Over the years, effective strategies have been devised by researchers to provide the end-users with efficient resolutions to their problems. Some of the strategies have been discussed below: Physical Aspects Technology Used for Help Desk The foremost consideration that needs to be made to improve the help desk service is to analyze the type of technology that has been adopted in the respective department. Hoffman (1996) stated that the technology should not be too advanced or complicated for the personnel; the technology should facilitate their operations to become efficient, rather than complex. Complicated operations might prove to increase the service time for every customer. Ergonomics The ergonomics, i.e. layout of a help desk center also plays an important role in its effectiveness and management. Bayan (2003) explained that the layout and design should be able to facilitate team work; the employees should be able to communicate with each other in case of any query since every employee possesses his own areas of expertise. An employee might need help in resolving an issue in an unfamiliar area of expertise. Although, the distance between the help desk representatives’ workstations should not be so less that they are not able to hear their clients clearly. Working Environment The representatives need to be provided with a comfortable and healthy environment. If the help desk resources are not satisfied with their working conditions then they will not be able to communicate with the clients in a positive manner. Appropriate chairs and headsets should be provided to the representatives to help them offer a commendable service to the clients. Management Aspects Defined Goals The management should identify their goals and then communicate them at all levels of the help desk employees. Bayan (2004) pointed out that the presence of defined goals enables the management to direct the employees towards certain goals and conduct employee trainings in an accor ding manner. Performance management can also be performed with respect to the defined goals and expectations. Understand the Customer with a Positive Attitude Bayan (2004) quoted statements of a CEO of a company, who stated that the help desk representatives should be able to understand their clients and their respective environments. The issue might be very trivial or very complex; in both cases, the representative should listen to the customer carefully and understand that he is experiencing distress due to the matter. The attitude of the representative should be comforting and helpful so that the customer also cooperates in answering the questions. The representatives should be trained to convince the clients that they are on the clients’ side and everything shall be done in their power to resolve the matter. Suitable Performance Measures Bayan (2004) provided an interesting categorization of different types of help desk representatives; the comprehension of the categoriza tion is relevant so that appropriate attributes can be chosen to analyze the performance of each type of employee. Knowledge workers are representatives who have extensive knowledge about the products and prove to be very effective at resolving complex problems. Process workers are repre

Business Entity Regulations Paper - Essay Example Next comes the most important part. If it is in the form of sole proprietorship or general partnership, the entity might not require registrations but if it in the form of Corporations, LLCs or LLPs or limited partnerships, it requires business filings with the Kansas Secretary of State. Also, if the business is in the form of partnership (limited or limited liability), non-profit, limited liability company or an corporation, the entity has to be registered with the State of Kansas. The business entity is granted an Employer Identification Number (EIN) which is a federal tax identification number. It is essential for the employers to have EIN before they hire any person. Apart from these mandatory factors, the entity also has to be registered for the state taxes and try and obtain businesses licenses and permits from the state as well as the local governments to function legally. Last but not the least, for the start-ups, guidance are provided to hire the employees at the first place. The annual filling report can be obtained electronically or online. At the outset, the name of the business entity and the identification number of business identification as per Secretary of State’s record has to be entered. The business entity (Lario Oil and Natural Gas in this case) should have delinquent and active status to file online. Also the business entity must possess credit card facility and checking account. As the Lario Oil and Gas Company is a profit entity, it has to pay a flat fee of USD 50. The due date for the annual report can be found by conducting a business entity search or contacting the office of the Secretary of State. The other important aspect of the procedure is that the online option is applicable only to the companies having addresses at the United States and Canada. If the company has address in any of the other nations, it has to mail the annual report in paper document to the

Determination of Dissolved Oxygen In a Water Essay Example for Free

Determination of Dissolved Oxygen In a Water Essay INTRODUCTION In an alkaline solution, dissolved oxygen will oxidize manganese(II) to the trivalent state. 8OH-(aq) + 4Mn2+(aq) + 2H2O(l) ï ¼ Ã¯ ¼ Ã¯ ¼Å¾ 4Mn(OH)3(s) The analysis is completed by titrating the iodine produced from potassium iodide by manganese(III) hydroxide. 2Mn(OH)3(s) + 2I-(aq) + 6 H+(aq) ï ¼ Ã¯ ¼ Ã¯ ¼Å¾ 2Mn2+(aq) + I2(aq) + 6H2O(l) Sodium thiosulphate is used as the titrant. Success of the method is critically dependent upon the manner in which the sample is manipulated. At all stages, every method must be made to assure that oxygen is neither introduced to nor lost from the sample. Furthermore, the sample must be free of any solutes that will oxidize iodide or reduce iodine. Chemicals: Manganese(II) sulphate solution – prepared by dissolving 48 g of MnSO4.4H2O in water to five 100 cm3 solution; alkaline potassium iodide solution—prepared by dissolving 15 g of KI in about 25 cm3 of water, adding 66 cm3 of 50% NaOH, and diluting to 100 cm3; concentrated sulphuriv(VI) acid; 0.0125 M sodium thiosulphate solution; starch solution (freshly prepared). Apparatus: 250 cm3 volumetric flask, 250 cm3 conical flask, measuring cylinders, titration apparatus, magnetic stirrer Procedure: 1.Use a 250 cm3 volumetric flask to collect water sample. Fill the flask completely with water without trapping any air bubbles. 2.Add 1 cm3 of manganese(II) sulphate solution to the sample using a pipette. Discharge the solution well below the surface (some overflow will occur). 3.Similarity introduce 1 cm3 of alkaline potassium iodide solution. Be sure that no air becomes entrapped. Invert the bottle to distribute the precipitate uniformly. [Hazard Warning: Care should be taken to avoid exposure to any overflow, as the solution is quite alkaline.] 4.When the precipitate has  settled at least 3 cm below the stopper, introduce 1 cm3 of concentrated sulphuric acid well below the surface. Replace the stopper and carefully mix until the precipitate disappears. A magnetic stirrer is helpful here. 5.Allow the mixture to stand for 5 minutes and then withdraw 100cm3 of the acidified sample into a 250 cm3 conical flask. 6.Titrate with 0.0125M sodium thiosulphate until the iodine colour bec omes faint. Then add 1 cm3 of starch solution and continue adding the thiosulphate solution until the blue colour disappears. 7.Record the volume of thiosulphate solution used and calculate the dissolved oxygen content in the sample in mg dm-3. Remarks 1.If the water sample has a low DO value, it is recommended to withdraw 200 cm3 of the acidified sample into a 500 cm3 flask for the titration describe in step 5. 2.This experiment can be further developed into a project to study the extent of water pollution. (a)The water sample under investigation is divided into two portions. One portion of the sample is immediately analysed for dissolving oxygen using the Winkler method. The other portion is stored in the dark for five days. (b)Repeat the analysis with the water sample that has been stored in the dark for five days. The difference between the two measurements is the five-day biochemical oxygen demand (BOD5), measured in mg dm-3.

Reactions to The Birth of a Nation

Reactions to The Birth of a Nation Mohammad A. Mian The Emergence of Modern America It can be argued that no other film in American history has been as controversial as D.W. Griffiths silent epic film, The Birth of a Nation. The Birth of a Nation, which first premiered on February 8th, 1915, and was based on Thomas Dixons novel and play The Clansmen.[1] The film is set in the American Civil War and the period of Reconstruction during the 19th century, and chronicles the lives of two families, the Stonemans and the Camerons.[2] The Stonemans are an abolitionist Unionist family from the North, whereas the Camerons are a Southern family loyal to the Confederate cause during the American Civil War.[3] Throughout The Birth of a Nation, African Americans are portrayed as being savages, violent thugs, sexual predators, ill mannered brutes, and ballot stuffers. For this reason, despite the films positive reception among the American public and news outlets at the time of its release; The Birth of a Nation received a negative response from African Americans and the National Association for the Advancement of Colored People, both of which protested against the films premiere across American cities. Despite the criticism, the film was defended by various news outlets and Griffith himself. Many contemporary film critics and historians regard The Birth of a Nation as Americas first great cinematic feature, despite its controversial portrayal of African Americans. The focal point of The Birth of a Nation are two juxtaposed families, the Stonemans and the Camerons. Members of the Stoneman household are Austin Stoneman, an American legislator and abolitionist, his sons Phil and Todd, and his daughter Elsie.[4] The Cameron family consists of Dr. Cameron, a Southern physician and staunch Confederate after the outbreak of the Civil War, his wife Mrs. Cameron, his two daughters, Margaret and Flora, and his three sons, Benjamin, Wade, and Duke.[5] At the beginning of the film, Phil and Todd visiting the Cameron family estate in South Carolina.[6] Upon immediately seeing Margaret, Phil falls in love with her, whereas Benjamin is awestruck by a picture of Elsie.[7] A few months later, the American Civil War erupts, and the Cameron sons enlist in the Confederate Army, while Phil and Todd uphold their loyalty to the Union by joining the army of general Ulysses S. Grant.[8] During the war, Black militiamen attack and ransack the Cameron estate, but the wo men of the household are saved by a Confederate contingent which routs the militia.[9] The portrayal of African American soldiers as brutes and savages strongly correlates with the stereotypical portrayal of Blacks the filmmakers envisioned. By the conclusion of the war, Todd, Wade, and Duke are killed in the conflict, while Benjamin is captured and taken to a hospital in Washington D.C.[10] At the hospital, Benjamin meets Elsie, with whom he develops a romantic relationship. The deaths of Todd, Wade, and Duke were emotionally appealed to the films audience, many of whom likely lost relatives in the Civil War. During his stay at the hospital, Benjamin is informed that he is to be executed by hanging due his associations with the Confederate guerillas.[11] In order to seek a pardon for Benjamin, Elsie and Mrs. Stoneman meet with Abraham Lincoln, and both of them manage to convince the President to pardon him.[12] After President Lincolns assassination, Austin Stoneman and his fellow republicans impose harsh measures on wealthy White Southerners, such as land confiscation, ushering in the Reconstruction period in American history.[13] Austin Stoneman travels to the South Carolina to oversee the implementation of the reconstruction policies of the Republicans.[14] He is accompanied by a Mulatto governor, Silas Lynch.[15] Lynch is portrayed as having psychotic characteristics, a common stereotype of African Americans among White Americans in the late 19th and early 20th centuries.[16] In the Southern cities visited by Stoneman and Lynch, African American soldiers are seen harassing Whites, while triumphantly parading on the streets.[17] In these particular scenes, Black militias are portrayed as being ill mannered and brutish in comparison to the naÃÆ'Â ¯ve and gentle White Southerners.[18] During the regional elections, Whites are shown as being barred from voting, whereas African Americans cast multiple votes without any issue.[19] After the elections, the African Americans who are elected to South Carolinas legislature are portrayed as being ill mannered, as the film once again highlights seeks to portray them as being brutish.[20] Laws in favour of African Americans are also enacted, which require Whites to respect Black soldiers in their cities, and mixed marriages are also legalized.[21] All of these factors, culminate in Benjamins founding of the Ku Klux Klan to counter the ever increasing power of African Americans in the South.[22] After Elsie hears about the activities perpetrated by Benjamins organization against African Americans in the South, she abruptly ends their relationship.[23] Meanwhile, Bens sister, Flora commits suicide after being pursued by Gus, a Black freedman who seeks a romantic relationship with her.[24] Gus incontrollable carnal desires are meant to portray him as a sexual predator, a common stereotype associated with African American men during the late 1800s and early to mid 1900s.[25] After personally witnessing his sisters demise, Benjamin has Gus lynched by his fellow Klan members, and places his corpse in front of Lynchs house.[26] Lynch immediately issues orders to suppress the activities of the Klan, and in the process Benjamins father is arrested for being associated with the organization.[27] He is, however, ironically rescued by his loyal Black servants with Phil Stonemans aid.[28] After hearing of the imprisonment of Mr. Cameron, Elsie attempts to convince Lynch to stop his crac kdown on the Klan.[29] Lynch refuses and attempts to rape Elsie, but she is saved by Benjamin and other Klan members who also manage to capture Lynch.[30] The capture of Lynch by the Klan is meant to emphasize the heroicness of the Ku Klux Klan as defenders of White Americans, and stereotype African Americans as savages. In the following election day, Black voters are stopped from voting by members of the Ku Klux Klan, and Margaret and Phil, and Elsie and Benjamin are married.[31] The film concludes with the title Dare we dream of a golden day when the bestial War shall rule no more? But instead the gentle Prince in the Hall of Brotherly Love in the City of Peace.[32] Following its release in 1915, The Birth of a Nation was praised by American film critics writing for various news outlets during the following few decades, without any mention of the films racial stereotypes of African Americans. One notable review of the film is Seymour Sterns article BIRTHDAY OF A CLASSIC: The Twentieth Anniversary of Birth of a Nation Recalls Its Significance in The New York Times, which was published on March 24th, 1935. Despite their being a twenty-year gap between the films release and Sterns review, he reflected the view Americans had of the film upon its initial release. Stern wrote It appeared twenty years ago as an unforeseen and unprecedented phenomenon in the old fashioned movie world of the day. With it the cinema became one stroke of art, and its first masterpiece was acclaimed by the critics. Simultaneously was once and for all delivered from the gaudy dominion of the vaude-ville show, which at the time had a stranglehold upon it-and David Wark Griffith entered into the long and magnificent reign as the kin of directors.[33] Stern further praised the films impressive photography by stating The picture is so remarkable from such a variety of important aspects that it is not easy immediately to select any given one. Griffith introduced a multitude of technical innovations that have since become the part and parcel of filmcraft. Here for the first time he used night photography, self-focus photography, moving camera shots, lap dissolves, the split screen and acute camera angles. The low-angle shots of mounted clansmen looming over the frightened Negroes are unforgettable. His subtle use of the iris in this film marks the fruition of that device.[34] From both of these statements, it is evident that Stern had high regard for the film. In fact, he had such high regard for the film that he described it as one which innovated and transformed the entire motion picture industry. Sterns review of the film also showcase the prejudiced White Americans had towards African Americans, as he did not once mention the films controversial portrayal of Blacks as a hindrance to the films visual magnificence.[35] Furthermore, Sterns referral to African Americans as Negroes further suggest that he largely agreed with their portrayal in the film, which is not surprising considering the fact that African Americans continued to be stereotyped in American media until after the Second World War. While Stern had nothing but praise for the film, the National Association for the Advancement of Colored People protested against the film, as did African American veterans of the First World War. In the year of and years following The Birth of a Nations release, many African Americans protested against its release in theatres. While the National Association for the Advancement of Colored People opposed the film immediately upon its initial release, they did not take direct court action against it until after the First World War. The NAACP launched its court case against the film in the State of New York in 1921, and it was covered by The New York Times in an article titled FOES OF KLAN FIGHT BIRTH OF A NATION: Ask Motion Picture Board to Forbid Revival Here-Griffith and Dixon Defend Film. The article, published on December 3rd, 1922, stated Demands that a revival showing of The Birth of a Nation be prohibited in this state as a glorification of the Klu Klux Klan and part of a local drive by Rev. Oscar Haywood to increase membership of the Klan were made yesterday at a hearing before the motion picture commission of the State of New York by Walter F. White, Assistant Executive Secretary for the Advancement of Colored People; Henry W. Shields, Senator Elect from the 21st District; and Alderman George W. Harris.[36] The NAACPs protests were carried out against a rescreening of the film in the State of New York in 1921.[37] Many of those involved were influential members of the African American community, and they were displeased by their portrayal in the film.[38] Eventually the protest resulted in a court case against the film, in which D.W. Griffith was also present.[39] Unfortunately for the NAACP, the judge of the case ruled in favour of the films screening by stating that it did not, in any way, promote the Ku Klux Klan, but rather, was a reflection of post-Civil War America.[40] The protests showcased the racial tensions present in the United States during the early 20th century, and they also reflected upon the desire of African Americans to see the film have its theatre permits revoked. For many African Americans, the film added to their negative image among many White Americans, an image which they sought eradicate. To make matters worse, the judicial authorities did not support the ple as of the NAACP. However, opposition to the film existed even before the official involvement of the NAACP, as in May 1921, African American war veterans protested against the films screening in front of the Capitol Theatre in New York.[41] In May 1921, African American veterans of the First World War and their wives protested against the screening of The Birth of a Nation in Capitol Theatre in New York. On May 21st, 1921, Negroes Oppose Film was published in The New York Times, and it covered these protests. The article reflected the opinions of the war veterans on the film by stating Negro ex-servicemen in uniform, flanked by negro women, gathered in front of the Capital to protest against the revival of The Birth of a Nation. Some of the pickets carried placards which read We represented America in France, why should The Birth of a Nation misrepresent us here? Others distributed circulars published by the Nation Association for the Advancement of Colored People which demanded, Stop the Klu Klux Klan propaganda in New York.[42] Ultimately, these protests did not result in a victory for the picketers, as five of their organizers were arrested by the police, including three women, although, they would all be released within a few days.[43] The failure of the protests evidenced the lack of regard the American political establishment had for African American war veterans and the stereotypical portrayal of their community in the film. In fact, D.W. Griffith continued to defend the film, and after the May protests, he was quoted by The New York Times as saying It is a source of regret to me that purely advised people are endeavoring to stir up animosity against The Birth of a Nation. The opposition is misguided, and was misproven and laid away many years ago. The leading villain in the story is a white man, who leads a misguided following into conflicts which do not reflect upon the negro. It there were the slightest ground for protest against the film it seems to me that white men would have claim to it than negroes. I shall be quite willing, however, to submit the matter under oath to the consideration of the court.[44] Griffiths comments are not surprising considering the popular attitude towards African Americans at the time. However, his assertion that African Americans were not the leading villains in the film has no justifiable ground considering the films stereotypical portrayal of them. It is also interesting to note that Griffith was open to take the matter to court. Considering the lack of regard American courts had for African Americans at the time, this is also not surprising. The lack of sympathy for African Americans among American courts is further evidenced by lack of intervention by federal courts against the film. For this reason, despite a ban on the film in three states and a few cities upon its initial release in 1915, it seemed that the film would continue to be screened in American theatres due to its popularity among the White populace.[45] Indeed, the NAACP continued to protest against the film up to the 1950s, as the film was continuously revived in American theatres. In 1950, picketers rallied against the revival of The Birth of a Nation outside the Beverly Theatre at 823 Third Avenue.[46] The protesters were upset the controversial film was being screened in the New York once again, despite it being 35 years since its initial release. The President of the NAACPs branch in New York, Lindsey H. White, led the protests, which was covered by The New York Times article FILM REVIVAL PROTESTED: N.A.A.C.P. Pickets Birth of a Nation at Beverly Theatre.[47] According to the article The revival of D.W. Griffiths silent-film classic The Birth of a Nation, was protested yesterday by Lindsey H. White, president of the New York branch, National Association for the Advancement of Colored People. Mr. White stated that the film, now being shown at the Beverly Theatre, 823 Third Avenue, distorts the historical truths of Negro and White in the reconstruction governments that were set up in various at the close of the Civil War. The NAACP has been picketing at the theatre since Saturday.[48] The article reflects upon the frustration among African Americans to have the films screening in the Beverly Theatre stopped. It also showcases that while it had been three decades since the films release, American attitudes towards the films content largely remained the same. Despite this, the popularity of the film had largely declined, as Americans became more interested in the Western genre of films in the 1950s and 1960s. With the decline of the film, it has become common knowledge that the film is no longer as popular, nor as widely viewed as it once was since the 1970s. For contemporary film historians from the 1990s onwards, the film is still regarded as one which transformed the American film industry. Perhaps no lines from a contemporary critics review of The Birth of a Nation better capture the films legacy on American cinema than these from Molly Haskells article In The Birth of a Nation,: The Birth of Serious Film in The New York Times The defining moment for the motion picture as a mass medium, an art form and a disturbingly powerful social force occurred on a bitterly cold night on March 3, 1915, at the Liberty Theatre in New York. It was the world premiere of D.W. Griffiths The Birth of a Nation, an event of such cultural magnitude that 80 years later, controversies still rage about the film among film scholars about its racially charged images.[49] Throughout her review, Molly praises the film for its ground-breaking innovations, vivid, imagery, and ability to keep an audience engaged, which is remarkable for a film 2 hour and 40 minutes long silent film produced in the early 20th century.[50] She is, however, critical of the films content, especially its negative portrayal of African Americans, as she does not agree with their stereotypical mannerisms in the film.[51] Nevertheless, she concludes her review by stating In Griffiths masterpiece sublimity of expressed was marred by melodramatic racism. Yet The Birth of a Nation, warts and all, remains a milestone: the movie that catapulted the medium from its 19th-century peep-show origins into its status as the great new art form of the 20th century.[52] Thus, it can be said that, while The Birth of a Nation remains a controversial film among, there is no doubt it transformed the film industry into a corporate giant. Upon its initial release in 1915, The Birth of a Nation was positively received by the American public and news outlets alike. However, the film was staunchly opposed by Africans Americans for its stereotypical portrayal of their community. Furthermore, the film reflected the tensions which existed between African Americans and White Americans from the late 19th to mid 20th century. The National Association for the Advancement of Colored Peoples was at the forefront of the opposition to the film, and remained so until the 1950s, after which the film declined in popularity. Almost all film historians agree that the film innovated the American film industry. However, they have criticized the film for its discriminatory portrayal of African Americans.

Lady Macbeth Responsible For Duncans Death Essay -- essays research pa

ohn Keating English Honors Lady Macbeth Must Take Some Blame for Her Husband’s Destruction In Macbeth, a play written by Shakespeare, Lady Macbeth is partially responsible for the destruction of her husband. Lady Macbeth is not a monster without feelings, however she is tricky and cunning when she influences Macbeth to kill Duncan. Lady Macbeth’s ability to influence her husband leads the audience to believe that she is the primary cause for the destruction of Macbeth. The audience is also led to believe that Lady Macbeth is responsible because she makes up the details of the plan to kill Duncan, while Macbeth was considering not even going through with the murder. Although Macbeth had the thought of killing Duncan, he would not have acted on that thought unless Lady Macbeth persuaded him. Lady Macbeth is sly person, able to manipulate her husband, and this ability to manipulate Macbeth makes her partially responsible for the destruction of Macbeth. Lady Macbeth knows that her husband is too kind to kill Duncan without her help she fears â€Å"thy nature; / It is too full o’th’ milk of human kindness / to catch the nearest way† (I.v.16-18). She is very much aware of the fact that she needs to push Macbeth to kill Duncan or else he will not do it. We see Macbeth’s hesitance to murder the king when he lists reasons not to kill Duncan in Act 1, when he says, â€Å"He’s here in double trust: / First, as I am his kinsman and his subject, / Strong both against the deed; then, as his host, /...

From their perspective: Children dealing with divorce Essay -- Social

The decision between a husband and wife to end their marriage due to irreconcilable differences has become an issue of epidemic proportions in the world today. Divorce is affecting people of all ages from the oldest to the youngest, tearing families apart. While the husband and wife getting the divorce are putting an end to what many of them once thought would be the best thing that would ever happened to them, it is their children who reap the most severe consequences. Children who were once looked after by both parents must adjust to living with one parent or moving back and forth between the two along with numerous other adjustments. The effects of divorce are not limited to practical adjustments alone, but research also indicates that children who go through the divorce of their parents experience physical and psychological troubles as well. According to recent research if current divorce rates remain steady, one in four children will go through the divorce of their parents befor e they are sixteen (Doweling & Gorell-Barnes, 1999). Another statistic shows that between 1972 and 1997 more than a million young children were involved in divorce each year (Zinsmeister, 1997). It is imperative in our society that is experiencing divorce so rampantly that we understand through research and observation the effects divorce has on children. The effects of divorce on children has been an issue of great controversy among professionals and parents alike. Research is inconclusive in many areas but enough evidence has been gathered to conclude that divorce does indeed have an impact on children. The effects of divorce, how much a child is impacted and how long the impact of divorce lasts, hinges largely on the age of the child when they ex... ...hat a child may experience after a family breakup (Jost & Robinson, 1991). Though the research presented here has focused on the negative effects divorce has on children there are instances where children hardly experience any ill effects from divorce. This is usually the case when the child’s parents are in abusive relationships or they are able to continue healthy relationships with both their parents. Sadly this is the exception and not the rule for children dealing with divorce. Despite the fact that there are several different opinions concerning the effects divorce has on children the majority of researchers agree that having married parents offers many benefits to children. These include but are not limited to, a higher standard of living, exposure to effective parenting, less stress overall and are more likely to succeed in school (McGuiness, 2006).

The Practice Of Concrete Repair Health And Social Care Essay

Concrete fix can be defined as the act of regenerating, reconstructing, or replacing of any concrete or concrete surfaces after initial arrangement ( Smoak et al, 2002 ) . In general, the demand for concrete fix can originate from different causes which may change from minor concrete holes or cracks- such as ensuing from minor imperfectnesss due to snap-tie holes or she-bolt holes, to major amendss ensuing from external factors or structural failures. In pattern, it is found that the bulk of the defects can be repaired or made good, while in some instances it is frequently found that the rebuilding of the single member or construction is frequently economical ( Allen et al, 2005 ) . It is agreed in general that the protection and the fix of the concretes are complex undertakings which requires particular attending and incorporate cognition of different specializer Fieldss. Due to the explosive growing of economic systems around the universe and due to the increased investing in substructures ( particularly in footings of care, Restoration and fix ) in the recent old ages, the fix and protection of concrete constructions has become a major subject of both scientific and economic involvement. As a consequence, the building industry has faced many challenges and demands. Underneath these demands lies the fact that the concrete construction deteriorate over clip at unbearable rates. As such, it is extremely necessary to develop the ways by which the life of the concrete constructions can be increased. There is besides a demand for appropriate tools and techniques to transport out the undertaking of fix and care of the concrete constructions within the limited budgets available. It is besides of import to see the importance of environmental conditions to which the concrete constructions are exposed while sing the tools and techniques employed for the fix of the constructions. The field of concrete fix calls for the integrated cognition ( expertness ) of different scientific Fieldss. The basic thought behind this fact is that the edifices or the concretes are confronting different environmental or external conditions and around the universes, the field pose many challenges to both the academe and the practicians likewise. Added to this, the fact that many edifices have their ain history and nature, it becomes necessary to develop and implement single schemes and solutions for the protection, fix and care of concretes. As a consequence of these complications, different basic schemes and solutions has been developed of the fix of the concrete constructions ( Raupach, cited in Alexander et Al, 2009 ) . This highlights the fact that this country requires knowledge from different Fieldss and that the sphere of the topic is more of interdisciplinary in nature.2.2.1 The pattern of concrete Repair:There are different criterions to which the pattern of fix of the c oncrete should be carried out. EN 1504 provides 43 methods to mend and protect the concrete constructions which are based on 11 different rules. However, it is by and large recommended that the interior decorator can take the appropriate solution depending on different conditions like the economical and proficient considerations ( Alexander et al, 2009 ) . It has besides been recommended in the old surveies that while choosing the optimum methods for different state of affairss, the interior decorator should look into in item the particular inquiries such as the needed degree of care, lastingness, and the sustainability ( ibid ) . Many writers have based their plants on the subject of concrete fixs ( Wall and Shrive, 1998 ; Kuhlmann, 1990 ; Plum, 1990, etc ) . Though there are many methods or criterions sing the concrete fixs, it can besides be noted that there is no standard design specification for the fix of the concretes. It can be argued from an beginning that a proper apprehension of why the spots fail could perchance cut down the figure of failures. However, due to the absence of standard design process for the fix of the concretes and the deficiency of apprehension, many research workers have now concentrated their attempts towards understanding the lastingness of fix spots.2.3 Adhesion between the concretes:In the field of concrete research, the adhesion between the concrete is one among the largely researched subjects. This has been argued to be an of import facet that influences the lastingness and the dependability of the spot up or the fix works ( Czarnecki et al, 2007 ) . In general, adhesion which can be considered as a basic issue in the fix of the concretes can be defined as the attachment of two stuffs in contact ( Czarnecki, cited in Alexander, M. G. , et Al, 2009 ) . The EN 1504-10 criterions ( European Standards ) used the term ‘bond ‘ to bespeak the adhesion that takes topographic point between the old concrete and the new concrete. As such, it is an of import factor that can besides find the effectivity of the fix. Fiebrich ( 1994 ) divided the adhesion mechanisms into three types ; mechanical interaction, chemical bonding and thermodynamic mechanisms. The European Standards, EN 1504 provides two ways of look of the formulated bond degree consequences of the adhesion ( Czarnecki, cited in Alexander, M. G. , et Al, 2009 ) . Threshold value in MPa ; towards structural fix ( EN 1504-3 ) : & gt ; 2,0MPa ( Class R4 ) , & gt ; 1,5 MPa ( Class R3 ) ; Pass/fail standards towards structural bonding ( EN1504-4 ) e.g. hardened concrete-to-hardened concrete or fresh concrete-to-hardened concrete: the trial shall ensue in break in the concrete. Once the bond is formed between the concretes, the bond can so be said to be effectual merely if the freshly formed bond ensures an even distribution of the emphasiss and an effectual transportation of burden without failure. Specifically, it has been found that the addition in adhesion, consequences in higher tolerance on non-compatibility belongings of both the old concrete and the new covering stuff ( Czarnecki et al, 2007 ) .2.4 Factors impacting Adhesion:There are many basic theories on adhesion that describe the mechanisms of the attachment between the old concrete and the new sheathing stuff. The chief theories pointed by different writers on the subject are the soaking up theories and the mechanical blocking theories ( Emmons et Al, 1994 ; Santos et Al, 2007 ; Maerz et Al, 2001 ) . Briefly, in the first theory associating to the thermodynamic surface assimilation the intermolecular forces or the Van der waal forces, the chemical linkage through the interface and the H affair increases the bond between the old and the new concrete. The 2nd theory of mechanical blocking can be broken down at two degrees foremost macroscopic in which the raggedness of surface creates mechanical blockings between shea thing and concrete and secondly at microscopic degree, the surface porousness at the interface substrate, comparable to a micro-roughness, facilitates grounding by tangle of hydrates, Bouksani et Al ( 2010 ) . Czarnecki ( 2009 ) in his research about the adhesive facets of the concrete bonds gave a important decision. He concluded that there are many factors impacting the adhesive strengths. These included: The belongingss of the fix stuffs: this included, viscousness, shrinking during puting, surface tenseness, weirdo, etc. Old concrete ( concrete substrate ) : strength of the stuff, presence of drosss, clefts present on the surface and the micro clefts, porousness of the stuff, the raggedness of the surface, etc, . The consequence of the environment: the degree of temperature- the alteration and the rate of alteration, presence of moisture- humidness degree and the alteration of humidness degree, the phenomenon of transportation- suction due to capillary consequence, the loading-mechanical burden, ageing, consequence of corrosion etc, . All these factors mentioned supra could act upon the bond between the concretes. Many of the factors could increase the bonds between the concretes but, in most of the instances, these grounds cause devastation in concrete bonds. Due to these grounds, it is obvious there is still a demand for the High Adhesive Repair Materials to be used in the fix patterns in order to turn to these issues. It has been identified that adhesion will depend on many factors. These are chiefly due to the phenomena that take topographic point at the interface country of the concretes ( Slater, 2001 ) . The chief phenomena includes, raggedness of the stuff surface, presence of wet on the surface, the humidness degrees of the external environment, external burden, wetability of the surface, the belongingss or the influence of the linear stuffs, etc, . The importance of surface raggedness, wet status and bring arounding status is frequently highlighted in many researches. It has been said that the first measure in fix or the care of the concrete after taking the method is to fix the surface of the bing concrete on to which the concrete is to be laid. This may include the remotion of the bing deteriorated concrete bed so that this can be replaced by the new stuff. The strength will depend on the grade of attachment of the new stuff on to the bing stuff. However, the influence of the raggedness and the wet of the surface besides contribute to the overall bond between the old and the new concrete. Therefore, it is really of import to guarantee that the wet and the roughness quality of the surface is achieved to the needed degree before the new concrete is laid on to the bing concrete ( Courard, 2000 ) . The difference in the consequence of the researches carried out by different research workers could be observed on ; the status under which the hardening is carried out ; the humidness status ; the bonding agents used in the experiment ; the temperature at which the trial is carried out ; the age of the specimen ; the type of the trial employed ; the design/setup of the specimen, etc. To this point, Julio et Al ( 2004 ) argued the importance of different trial parametric quantities to be considered while comparing the consequences. They noted that these differences produced contradictory consequences and as such, there is no consensus in the findings. Therefore it is by and large agreed that the comparing of findings appear to be hard. But, to acquire an overview of the current cognition and substantial findings some of the major factors that affect the adhesion between concretes are discussed below.2.4.1 A individual survey sing assorted factors:Wall et Al ( 1988 ) investigated the factors impacting the bond between the old and the new concrete in concrete fixs. The experiment was carried out to research the effects on the bonds based on different parametric quantities. These parametric quantities included the thickness of the bed of the bonds, the ratio of the cement and H2O used in fixing the howitzer, the influence of different conditions under which the hardening procedure was carried out, the influence of wetting the surface of the old concrete onto which the new concrete is laid, the influence of the hold between blending the copolymer PVA bonding agent and its application to the old concrete. The major difference that can be noted from the survey carried out by Wall et Al ( 1988 ) and other researches is the difference in the bonding strength of the specimens incorporating the Portland cement to the specimens that contained Copolymer PVA agents. It was observed in their survey that the specimens that contained Portland cement howitzer were stronger than the PVA agent 1s. Major differences were besides found in the trials associating to the thickness of the new concrete bed or the repair stuff applied to the older concretes. It was found that the strength increased when the thickness reduced ( 1/8 in and 3/16 in proved stronger than the 1/4 in bed ) . However, the writers do non give farther account sing this phenomenon. Notably, the research did non supply clear account about the affect of cement to H2O ratio. The compressive strengths for different H2O to cement ratios were found to be different. Ultimate compressive emphasis for a H2O cement ratio of 0.32 was found to be lower ( 1870 pounds per square inch lower ) than the one which had a H2O cement ratio of 0.40 by this observation, Wall et Al ( 1988 ) concluded that the bond strength between the two concretes decreased as the H2O cement ratio besides decreased. One another determination was about the surface status of the substrate concrete before the application of the new bed. It was found that the pre-wetting of the substrate before the application of the new bed resulted in bettering the strength of the bond. In instances when the PVA bonding agents dried before the application of the fix stuff to the surface, it was found that the compressive strength of the bonds decreased by 10 % . However, it was besides found that the howitzers with PVA modified cements produced higher bond strength. One other of import facet found was the influence of the bring arounding status on the strength of the bonds. Different specimens were cured under different hardening conditions. It was found to impact the ultimate strength. Though it was found that the specimens that were cured under high humidness conditions ( 100 % ) had greater strengths than the 1s cured in less humid conditions, the differences were non considerable. Hence it was concluded that the grade of influence was little when sing other parametric quantities.2.3.2 Influence of Material for the Repair:Though there are many methods that can be followed while mending the concretes, it is advised that proper attention should besides be taken while sing the fix stuff. Once these have been selected, the following of import measure is to clearly understand the conditions that the concrete will see over its life. Some of the cardinal factors are the conditions conditions, chemical exposures, the scope of temperature, the magnitu de of the burden and the continuance to which the concrete is exposed to the burden, the nature of the spot ( aesthetic or structural ) , etc. It is of import to see these facts because different researches in to the field of the concretes have shown that the public presentation of the spot stuff varies under different conditions. It can be argued that proper attention should be taken while choosing the spot stuffs by giving proper consideration to the stuff belongingss of the substrate concrete and the old concrete and the conditions to which the concrete will be exposed over its life. It could be recommended that the stuffs with different belongingss could be selected merely if the bond strengths are non affected and further it does non do any lastingness jobs ( Wipf et al, 2004 ) . However, it is critical to guarantee that the internal emphasiss do non transcend the tensile emphasiss of the substrate ( Wipf et al, 2004 ) .Influence of Adulthood:The bond between the substrate and the new concrete has besides been linked with the adulthood of the sheathing. This was pointed by Delatte et Al ( 2000 ) . To lucubrate over this subject, they linked the adulthood of the sheathing to the bond strength, which in bend was related to the overall strength of the stuff ( interface ) . It was concluded in their research that the early- age strength of the concrete had important consequence on the bond strength and the tensile strength of the stuff. These groups of researches have besides highlighted that sheathing or the interface as one of the major zones of the break. Therefore, harmonizing to Beushausen and Alexander ( 2008 ) , mechanisms of bond failures in relation to the parametric quantities of stuff and the location of failure will necessitate farther research.2.3.3 Influence of Test Method:It has been argued in the old diaries that the quality of the bond strength can be influenced by a scope of parametric quantities associating to the stuff and the conditions o f the environment ( Alexander and Beushausen, 2008 ) . Another of import factor is the trial method used. There are assorted test methods proposed to measure bond belongingss and public presentation of fix stuffs in general. They include the tensile bond, slant-shear, twist-off, flexural and patch trial etc. , However each trial is influenced by different combinations of factors and can non give entirely a full image ( Austin et al,1999 ) . For case, Momayez et Al ( 2005 ) reported in their survey that in few instances bond strength from some trials were upto eight times higher than those obtained from other type of trials. Additionally, it is of import to observe that the mechanical adhesion in tenseness varies well from that in shear ( Alexander and Beushausen, 2008 ) . Therefore, it can be argued that the positions of different writers ‘ will besides depend on the pick of the methods used in finding the bond strength.2.3.4 Condition of the surface of the interface:The bond strength besides depends on the general status of the surface like cleanliness. There is besides particular industry criterions to which the cleansing and preparing of the concrete surface should be carried out before the fix is carried out ( Charles and Scott, 1997 ) . In add-ons to these criterions, there are besides many standard recommendations provided by different makers of the fix material merchandises. The more normally known industry criterions are: ASTM D 4258 Surface Cleaning Concrete for Coating ; ASTM D 4259 Abrading Concrete ; ASTM Standards for Cleaning, Surface Preparation, and Testing ; ASTM D 4285 Indicating Oil of Water in Compressed Air, etc. One of the major points to be considered while cleaning the surface is the presence of the surface contaminations. This can be in the signifier of liquids or solids. There is a possible menace that these contaminations could jobs for the application of the stuff, hardening, adhesion or other things which are critical for organizing the bond between the two concrete beds ( Wipf et al, 2004 ) . It is noted that the presence of dust and unsound concretes are besides a major barrier for organizing a strong bond between concretes. It is recommended that the usage of the doodly-squat cock be avoided when covering with the damaged concretes. Alternatively, the usage of the chisel and cock can guarantee that the structural belongingss of the concretes are non affected ( Ibid ) .2.3.5 Influence of Roughness:The influence of the raggedness to the bond strength between the concretes has been argued by many writers. It has been argued in the old surveies that the add-on of the ordinary concrete on to the interface that is unsmooth green goods better consequences than the 1 that was laid on to the smooth interface ( Garbacz et al, 2006 ) . These findings are similar to the 1s investigated by other writers excessively. Matana et Al ( 2005 ) identified in their research that the bonds between the concretes provided good bond strength when the stuff had unsmooth interface. Similar consequences were besides given by Courard ( 2006 ) . Roughness of the substrate surface is frequently presented as the most of import factor to accomplish a good bond. This betterment is chiefly assigned to the addition of the contact surface ( Talbot et al 94, Santos et al 07 ) . On the other manus through the survey done by Perez et Al ( 2009 ) , while analyzing about the correlativity between the raggedness of substrate surface and debonding hazard, they interpreted by their consequences that increasing of raggedness does non heighten the bond strength. The argument over the influence of raggedness is still an on-going issue and as such, the consequence of the raggedness of the concrete surface over adhesion procedure is non really clear ( Austin et al, 1995 ; Czarnecki, et Al, 2003 ) . Some research workers have argued that there is influence of surface sums on the degree of adhesion that take topographic point at the interface. A seeable sum of ratios between 30 to forty per centums provided better consequences ( Fiebrich, 1994 ) . Fukuzawa et Al ( 2001 ) , argued the being of correlativity between roughness parametric quantities of the material surface and the adhesion strength. Though the raggedness of the stuff is an of import factor, some writers ( Silfwerbrand, 1990 ) have besides pointed the affect of micro clefts that are produced on the surface of the concrete when the surface is treated by different methods to accomplish the raggedness. These sorts of micro clefts are found to deteriorate the quality of the bonds that is formed between the concretes ( Garbacz et al, 2005 ) .2.3.6 Influence of wet:With respects to the presence of wet, recent surveies provide a better apprehension to the subject of influence of the wet on the strength of the bond. Bouksani et Al ( 2010 ) , in their survey on the influence of the raggedness and wet of the substrate surface on the bond between the old and the new concrete, suggest that the incursion of the sheathing stuff into the substrate concrete is chiefly dependent on quality readying of the substrate surface. They besides suggested that the surface of the substrate should be saturated with dry surface- which means that the surface of the substrate is non stagnated with H2O, so that it ensures that a good micro raggedness and a better thermodynamic surface assimilation is achieved. They suggest that the stagnancy of the H2O on the substrate surface can forestall the pores from absorbing the sheathing stuff which can ensue in a weak adhesion procedure. The overall consequence of over stagnancy is that, it will stand as a barrier in the interface zone cut downing the attachment procedure. On the other manus if the substrate stuff surface is dry with really low wet or no wet, this will ensue in the interface absorbing more H2O from the freshly laid stuff. Such a procedure will besides cut down the overall adhesion procedure as this could ensue in higher opportunity of uncomplete hydration of the cement. Therefore, it can be concluded that the wet needs to be present merely to a optimal degree. Excessively much wet or excessively small presence of wet will ensue in a weak adhesion procedure. Similarly, Xu ( 1999 ) besides studied bond strength utilizing oven dry, air dry and concentrated surface dry status of substrate. He reported that prewetting the surface of concrete substrate reduced the bond strength of the specimens used in his experiment from 0.64 to 0.12 MPa However, Saucier and Pigeon ( 1991 ) did n't happen any noteworthy difference between the bond strength of lab dried surface and pre-wetted surfaces in slant shear trial. In another survey, Austin et Al. ( 1995 ) did work on happening bond strength utilizing substrates with concentrated surface prohibitionist, saturated surface moisture and air dry wet conditions. They besides reported no important difference in bond strengths ( about 2.77 to 2.98 MPa ) due to the different wet status of substrate.2.3.7 Influence of Bring arounding Condition:There are a few researches carried out refering the affect of bring arounding status on the shear bond strength. Yee and Ibrahim ( 2010 ) in their survey on shear capacity of precast slabs investigated the difference in consequences for H2O cured samples and air cured samples. The consequences they got were changing with similar raggedness feature of surface but different bring arounding status. For case, a unsmooth surface produced higher shear capacity than a smooth one in air cured status whereas a smooth surface produced 16 to 18 % higher shear capacity in H2O cured conditions. Another noteworthy point was the influence of bring arounding status on the interface strength which was highly variable, as such it decreased by 30 % in smooth and unsmooth surface in H2O cured status where as for the air cured status it increased by 40 % between smooth and unsmooth surface.2.3.6 Influence of Bond Coat:It is common that some external agents are used in the mix to accomplish a higher degree of adhesion. Many writers have different sentiment sing this, chiefly the bond coats like polymer complexs. Some writers ( Silfwerbrand, 1998 ) argue that the bond coats can ensue in creative activity of an excess plane of failing. As a consequence, it has been advised to avo id the bond coats. Further, the bond coats could besides take to the decrease of the meshing consequence ensuing in an overall negative consequence ( Garbacz et al, 2005 ) . On the other manus these statements have been questioned by some other writers. Interestingly, harmonizing to some other writers ( Austin et al, 1995 ; Pretorius and Kruger, 2001 ) , the presence of the bond coats could increase the adhesion procedure between the two concretes. To this point, Garbacz et Al ( 2005 ) conducted a survey to look into the influence of surface intervention of the concretes on the adhesion mechanism between the concrete beds. Different surface intervention methods were used in order to accomplish different qualities of surface on the concrete stuff surface. Additionally, a fix howitzer with coat was applied to the old concrete and the adhesion was measured. The consequences showed that, in the instance of the sheathings applied without the bond coats, the adhesion procedure was influenced by the raggedness of the concrete substrate. Form this, it was concluded that the good bond strength belongingss can be achieved from the howitzer ( repair howitzer ) and the bond coat belongingss. It was further concluded that the belongingss of the bond coats and the howitzer helped in bridging the micro clefts and concrete pieces, and besides filled the surface abnormalities. Therefore, it can be concluded on the recent plants on influence of the surface on the adhesion between the surfaces the roughness status of the surface can be regarded as one of the contributing or act uponing factor in the fix of the concretes. From these treatments on the different factors impacting the bond it can be concluded that the consequences are non ever in consensus and there is still need for surveies to be carried out in this country for deriving farther penetration of the existent behavior of bond with regard to alterations in factors impacting it.2.4 Surface Roughening Technique:There are different ways in which the surface of the stuffs can be prepared to accomplish different raggedness conditions. However, the chief purpose of executing the surface intervention on the substrate is to the brand sure that the unwanted beds that might cut down the adhesion procedure are removed before the new beds of concretes are laid on to the surface. In add-on, this besides ensures that the entire country of surface contact is increased to the maximal degree. The forms and feelings achieved on the surface will depend upon the energy applied and chosen techniques. Roughening Techniques which does non deteriorate the mechanical unity of the substrate stuff must be used. It is of import to see the local status of the concrete under consideration. Consequently, common techniques like chisel and cocks, sandblasting, hydro-jetting, needle gunning, crunching or milling, hammering etc, may be used ( Garbacz et al, 2005 ) .2.4.2 Measurement of Roughness:The raggedness is by and large assessed qualitatively. But, placing the fact that this sort of raggedness rating leads to subjectiveness of consequences, there have been some efforts made to quantify the raggedness. For, case mechanical profilometry was used to distinguish polished and sandblasted concrete surfaces ( Courard 1998, Courard and Nelis 2003 & A ; Courard and Garbacz 2004 ) . Due to some defects of this procedure like viability with lone short surfaces etc. , another method of optical analysis was developed ( Perez et al 2003 ) in order to analyze big surfaces. Subsequently on, these two ab ove mentioned techniques were compared by Courard et Al ( 2006 ) and they concluded that with the combination of these two methods it is possible to acquire a really good description of â€Å" raggedness † at all graduated tables. They besides pointed out some restrictions of these methods sing the form of stylus which would do it impossible to take measurings on really unsmooth surfaces and other restrictions being really clip devouring etc. , In another survey by Courard et Al ( 2004 ) a point which is concluded is that a parametric quantity Xa which is the arithmetic mean of the going of the raggedness profile from the average line is the major discriminating parametric quantity for the comparing of surface readying techniques. In a new method for measuring the surface raggedness Abu Tair et Al ( 2000 ) , studied five different sorts of raggedness including needle gunning. They used a different attack for quantifying the raggedness by associating the sum of raggedness to Roughness Gradient of the raggedness profile obtained. They concluded that the raggedness gradient parametric quantity can give a proper indicant of the chapped surfaces. In this survey an effort is made to happen out a similar sort of parametric quantity to which the sum of raggedness can be related and the chapped surfaces can appropriately be categorized.
