Geometric Design Of Rural Roads Engineering Essay Free Essays

It is a good known fact that route accidents in South Africa are serious causes of concern. Harmonizing to the latest accident statistics at that place has been an addition in the figure of human deaths. Harmonizing to the article on the Arrive Alive web site ( Road decease toll ‘unacceptable ‘ ) [ 1 ] dated 3 January 2010, Transport Minister Sibusiso Ndebele is disappointed with the route decease toll, stating that one human death on the state ‘s roads is one excessively many. We will write a custom essay sample on Geometric Design Of Rural Roads Engineering Essay or any similar topic only for you Order Now Preliminary statistics released by the section on 2 January 2010 revealed that 1050 people had died in route related incidents during December 2009. N3 Road safety is non merely a major concern for South Africa but so a concern that requires the immediate attending of other states worldwide. The Commission for Global Road Safety has during June 2006 presented a study titled â€Å" Make Roads Safe † [ 2 ] that could hold an consequence on the manner we approach route safety. The study aims to concentrate on political and public attending and relates to the planetary route traffic hurt epidemic that claims the lives of 1.2 million people and hurts around 50 million yearly.

South Africa is in this class. It is of import that the cognition gained by high income states be transferred and implemented in South Africa. The N3 path is a popular path during vacations and with high volumes of rider and cargo traffic on the roads, there is prone to be serious and fatal accidents. Road fury, velocity and driver behaviors are non the lone cause of these accidents. Holiday periods are by and large during the rainy season and route elements, particularly drainage, contribute to accidents. Superelevation There are changing point of views and sentiments among civil technology professionals on the use of superelevation values given in the TRH 17 [ 3 ] and SANRAL ‘s Geometric Design Guidelines [ 4 ] . The geometric design considerations need to be reviewed particularly when it relates to route surface drainage at points where the route has no crossfall during development of superelevation. Presently the SANRAL Drainage Manual, 5th Edition Final Revision, p5-2 [ 5 ] recommends that the flow deepness during a 1:5 twelvemonth storm should non transcend 6mm. This is in contrast to the Highway Drainage Manual ( FHWA-TS-79-225 ) [ 6 ] recommendation of 4mm. Harmonizing to Highway Surface Design ( Transit New Zealand ) Manual [ 7 ] , the critical deepness for aquaplaning scopes from 4mm to 10mm depending on Sur and paving surfacing. The surface H2O deepness hence, should be restricted to 4mm for all but particular state of affairss where superelevation produces long, curved flow waies. There are three common particular state of affairss where surface H2O deepness may go critical, viz. , horizontal alliance curvature, intersections and inclines and superelevation development. 2.2 Why is the research being undertaken? Standards for superelevation where steep perpendicular classs have a direct consequence on drainage on horizontal curves have non been developed harmonizing to the TRB [ 8 ] . Drain jobs associated with superelevation has resulted in an addition ( particularly at route broadenings ) in vehicular accidents and a thorough survey of the surface H2O flow waies on route surfaces due to superelevation demands need to be farther investigated, researched and analysed. The proposed analysis and context of the research proposal will place the factors such as velocity impacting the vehicle kineticss at crisp or decreased horizontal curves where flow waies of surface H2O are debatable and can take to aquaplaning. Driver behavior during aquaplaning in concurrence with the geometric design of the roadway are factors considered in the research. This survey will be done under heavy vehicular traffic conditions during inauspicious conditions conditions. ‘Context Sensitive Design ‘ ( CSD* ) [ 9 ] for the geometric design of safer roads will be addressed in the research survey. 2.3 How will the consequences add to the organic structure of cognition? The TRH 17 papers was compiled to be a design guideline for the geometric design of rural roads in penchant to criterions. An aim of the TRH 17 was to continuously amend the bill of exchange papers, through audience between the governments, treatment with practicians and ongoing research. This has non happened. It is common pattern by geometric interior decorators to utilize the TRH 17 papers for the design of rural roads without oppugning the values obtained in the tabular arraies and graphs. The cogency of the guidelines should be judged by the geometric interior decorator in each specific state of affairs every bit good as the effects of going from the values suggested. Similarly SANRAL ‘s Geometric Design Guidelines have been developed to help design advisers. The inceptions of the guidelines stem from AASHTO [ 10 ] . Currently there is no criterions developed for SA and these guidelines are authority specific. Literature reappraisal The literature reappraisal will depict the current province of cognition on the component and will be researched. Applicable literature listed hereunder have been identified. * † Context sensitive design ( CSD ) asks inquiries foremost about the demand and intent of the transit undertaking, and so every bit addresses safety, mobility, and the saving of scenic, aesthetic, historic, environmental, and other community values. CSD involves a collaborative, interdisciplinary attack in which citizens are portion of the design squad. † 3.1 Reference certification Refer to list of mentions ( 11.3 List of Mentions ) . How will the literature reappraisal nexus with the job statement and research aims? The literature reappraisal gives a background and base cognition to develop in this research survey. Case survey As portion of the on-going committedness towards route safety, convenience and mobility, N3TC conducted a comprehensive route safety audit in 2006 [ 11 ] which highlighted velocity as the chief cause of accidents at assorted locations along the N3 between Cedara and Heidelberg. Sections where velocity bounds are posted necessitates forbearance, appropriate decreases in velocity and full concentration on the portion of drivers. Accidents in these countries frequently occur because drivers lose control due to rushing, every bit good as the high velocity derived functions between heavy and light vehicles. Mist and inauspicious conditions conditions have a important impact of driver conditions. Van Reenen ‘s Pass is one of the most beautiful subdivisions of the N3 exceeding the escarpment between the Free State and Kwazulu-Natal renowned for its slippery and unstable roads ( peculiarly as a consequence of the frequent brumous conditions ) .The route is steep, really steep in topographic points, and turns and turns as it follows the cragged terrain. The conditions is risky at times with high air currents capable of blowing trains, light vehicles and light trucks onto their sides. Snow has on a figure of occasions wholly closed the Van Reenen ‘s Pass, whilst mist and rain on a regular basis cut down visibleness and render the route faithlessly unsafe. It is of peculiar involvement the visibleness of a figure of skid Markss on the route surfacing and guardrail replacing. Traffic, in peculiar heavy traffic, increases yearly as the economic system grows. Trucks unrelentingly ‘grind ‘ up and down Van Reenen ‘s Pass twenty-four hours and dark, while during extremum traffic periods every bit many as 3000 vehicles per hr use the base on balls. Using September 2004 to August 2006 statistics [ 12 ] , the day-to-day norm traffic was 9100 vehicles, of which 2600 were big trucks ( 5 axles or more ) , about a 3rd of all vehicles. During the month of December 2007 recorded at the Van Reenen ‘s Pass, the mean day-to-day traffic reached 11000. The velocity derived functions between trucks in low cogwheel and the powerful new coevals of light vehicles is highly awful, both up and down the base on balls. High velocity derived functions ( 76 % of drivers exceed the velocity bound on the base on balls ) and failure to accommodate velocity in relation to fortunes, have contributed to 70 % of all accidents on the base on balls over this period. Th e consequences do non portray a pretty image and from a route safety point of position, Van Reenen ‘s Pass is the individual most unsafe subdivision of the N3. N3TC has identified and addressed route safety on Van Reenen ‘s Base on balls from three points of position, viz. technology, instruction and enforcement [ 13 ] . N3TC has implemented intercessions to cut down the figure of accidents on the base on balls but presently the greatest causes of accidents is by vehicle softness ( inoperative brakes in peculiar ) , rear-end hits due to high velocity derived functions, unsafe inter-lane tactics and driver freak out in utmost conditions conditions. Elementss impacting safety at superelevation The drainage conditions of the roadway in relation to the vehicle kineticss need to be farther investigated as superelevation along crisp horizontal curves with decreased sight distances presents a important degree of driver concentration. The driver tends to rectify the vehicular way. The surface stormwater run-off flow way along the horizontal curve effects natural braking forces which in bend can take to seaplaning ( or aquaplaning ) . Aquaplaning occurs when H2O force per unit areas build up in forepart of a traveling Sur ensuing in an uplift force sufficient to divide the Sur from the paving. During high strength rainfall events, a H2O movie builds up on the surface on the route. The hazard of vehicle aquaplaning additions as the deepness of this movie increases. The loss of maneuvering and drag force produced during aquaplaning may so do the vehicle to lose control, particularly when a guidance Sur is involved. Rainfall strength is the most of import environmental factor in hydroplaning. The hazard of dynamic aquaplaning is straight relative to the deepness of H2O in the route surface. This deepness is affected by a broad scope of factors that are contributed to by the environment such as the geometric design, paving design, drainage design and care and by the status of the vehicle. The geometry of the route has a big consequence on the H2O deepness and is the factor over which the geometric interior decorator has the most control. The length of clip H2O is able to remain on the route will act upon the deepness it achieves. Longer flow waies intend more clip to roll up rainfall and consequence in higher movie deepnesss. Changes in superelevation, reduced horizontal alliance and droop curves are some of the job countries where the incline is low or where H2O has to flux a long manner over the paving before being intercepted by a drainage system or dispersing into the next terrain. Superelevation alterations can ensue in long curving flow waies which may be debatable. Steeper longitudinal inclines can besides increase the flow way length and ensuing deepness. The paving texture deepness effects the H2O deepness by leting some of this H2O to flux between the sum or in channels supplying flow waies to let H2O in forepart of the Sur to be forced out under force per unit area. Porosity can besides be considered as some pavings such as open-graded porous asphalt allow H2O to run out through them, taking it off from the surface. Wheel path depressions have a important consequence on the drainage patterns increasing H2O deepness and concentrating flow. The N3 has changing pavement surfacing of which an analysis will be done sing the flow way on these surfaces. Pavement drainage solutions is indispensable to guarantee that no H2O is able to pond on the trafficable route surface, peculiarly in sag countries. This is critical in order to cut down the aquaplaning hazard. Vehicle features and behaviors are besides of import factors in aquaplaning. The velocity at which a vehicle needs to go to get down aquaplaning is determined by H2O deepness but besides by the vehicle ‘s weight and Sur features. The vehicle weight determines how much uplift force is needed to bring on separation and it follows that a lighter vehicle will aquaplane at a lower velocity. Higher Sur force per unit areas increase the aquaplaning velocity by cut downing the contact country between Sur and route, increasing the vehicle ‘s weight to country ratio. Tyre pace deepness besides affects aquaplaning the same manner as pavement texture, with deeper pace traveling the H2O off from the country of contact more efficaciously. While minimal tyre pace deepness and maximal velocity are both specified by jurisprudence, minimal weight and Sur force per unit areas are non. These are vehicle maker recommendations specific. In drumhead, drainage demands versus vehicle kineticss are the cardinal factors to be considered in the development of superelevation standards at decreased horizontal curves to minimise aquaplaning on the N3. Practical considerations such as Sur deepness, paving features and drainage solutions will be evaluated along the path. The assorted literature reviewed amplifies the demand for safer roads and the N3 is considered to be the most traveled path in South Africa. Research background Significant roadway debasement such as shining of sums, hemorrhage of bitumen and rutting depletes the clash supply available for cornering. This depletion consequences from the usage of a part of the clash supply to supply the necessary braking force required to keep velocity on the downgrade. The velocity of the vehicles on the roadway and the vehicle kineticss will necessitate to be analysed as differing vehicles have different clash forces exerted on the roadway. It can non be assumed that the relevant design standards for a auto is similar to that of a truck or frailty versa. As the Independent Engineer, my old audit studies [ 14 ] on the N3 has indicated the assorted surfacing failures. Skid Markss are significantly prevailing and N3TC/SANRAL/DOT accident studies will necessitate to be investigated as portion of the research survey. It is noted from the TRH 17 that the design vehicle is a individual unit truck. This unwanted combination consequences in a important lessening in the border of safety ensuing from roadway class, particularly for heavy vehicles. On long or reasonably steep classs, drivers tend to go faster in the downgrade than in the upgrade way. Additionally, research has shown that the side clash demand is greater on both downgrades ( due to braking forces ) and steep ascents ( due to the grip forces ) . Downgrades on horizontal curves may be debatable, and that accommodation for it may be desirable in some instances. There are no guidelines as to how this accommodation should be made for two-lane or multilane divided or undivided roadways. Some accommodation in superelevation rates should be considered for classs steeper than 5 % . This accommodation is peculiarly of import on roadways with high truck volumes and on low-speed roadways with intermediate curves utilizing high degrees of side clash demand. The superelevation alteration proposition high spots that this accommodation be made by utilizing higher design velocities standards for the geometric design of the roadway. More unequivocal counsel on this accommodation, every bit good as accommodation for other elements of the horizontal curve, is needed. The design velocity versus minimal curve radii of horizontal curvature needs farther probe to guarantee safety on crisp horizontal curves taking the other related factors like superelevation, etc into consideration. The article published in the Pretoria News, â€Å" Wet conditions causes a spike in route accidents † [ 15 ] refers to the important addition in roadway accidents during showery conditions. The drainage demands and vehicle kineticss in relation to superelevation design of the roadway will be investigated and researched. I have consulted assorted professional applied scientists, engineers [ 16 ] and independent advisers [ 17 ] in the transit industry. The response received was favourable in footings of the demand for farther probes of superelevation in relation to drainage demands and vehicle kineticss for roadway geometric design. Research jobs and purposes I am presently the IE ( independent applied scientist ) and have audited the everyday route care points of the N3 for the past 3 old ages. As such, I have entree to some informations to analyze as portion of the survey. Assorted subdivisions of the N3 are presently being upgraded or rehabilitated to better the quality and lifetime of the route due to vehicular traffic additions. There is important freight motion. This has resulted in an addition in vehicular accidents. My point of view on the design considerations adopted on the N3 is subjective as driver safety factors and other extenuating hazards of vehicular accidents need to be farther investigated. From a geometric design analysis point of view, road-widening and general roadway rehabilitation are designed harmonizing to the bing roadway conditions and drainage jobs associated with superelevation is prevailing. Ponding has been recorded and ocular grounds is prevailing in certain countries. The general stormwater design standards should be viewed and analysed otherwise from the Kwazulu-Natal conditions as opposed to the Free-State and Gauteng conditions as the overflow rainfall strength and clip of concentration varies significantly. This survey will sketch and place the undermentioned conditions with specific superelevation standards development on the N3 path: Superelevation standards at steep gradients ( turn overing to cragged terrain ) with reduced/sharp horizontal curves ; Drain jobs associated with superelevation ; Flow waies on route surfaces due to superelevation ; and Speed and Vehicle kineticss at crisp horizontal curves. Steep classs at crisp horizontal curves presents a unsafe state of affairs for traffic. The two scenarios where this status is prevailing is at broken-back curves on cragged terrain ( Van Reenen ‘s Pass specifically and other identified countries ) with multi-lane, 2-way roads ( whether it is divided or undivided ) and/or high velocity downgrade at/before perpendicular droop curves. At these locations, the perplexing factors of vehicle â€Å" off-tracking † , pavement incline ( crossfall ) , and pavement clash tests the drivers ability to supply right vehicle positioning without compromising control of the vehicle. It has besides been recorded that air current has been a cause of accidents as the vehicles can non ‘grip ‘ onto the roadway ( particularly at ‘Windy Corner ‘ on the Van Reenen ‘s Pass. From old design considerations, accident-related jobs have arisen where, as a consequence of Reconstruction, bing main roads have been rebuilt utilizing the 8 % -10 % superelevation rates in conformity with current guidelines. The rate of superelevation development is nevertheless non reviewed or adjusted. Research methodological analysis The research attack has a both qualitative and quantitative attack. The theoretical research will consist of mathematical analysis with mold and simulation. The current geometric design guidelines for rural roads ( TRH 17 and SANRAL ‘s Geometric Guidelines ) will be used as base certification for values in the research input. Case survey subdivisions of the N3 will be decided upon and N3TC, SANRAL and the DoT ( both national and provincial ) will be informed of the research survey. Data aggregation and statistical information will be sourced from the relevant governments with anterior consent. This research would necessitate: the reappraisal of current design guidelines ; the development of an action program to accomplish the research objectives ; the aggregation of statistical informations ( from SANRAL, N3TC, etc ) and other relevant information ; elaborate ocular appraisal and rating of the roadway subdivision ; Falling Weight Deflection ( FWD ) measurings will be performed at 50m intervals instead on the left and right exterior wheel paths along the subdivision identified ; rut and siting quality measurings will be measured in both wheel waies every bit good as texture deepness along the outside wheel way as portion of the FWD measurings ; Measurements of the stormwater sheet flow overflow deepnesss will be measured utilizing conventional agencies ; vehicle kineticss will be physically and theoretically analysed ; the rating of the effects of assorted options contextualized in geometric design guidelines and campaigner standards taking into consideration the CSD attack ; and the readying of extenuating hazards, route safety steps and concluding geometric design standards for superelevation, drainage demands taking into consideration the velocity and vehicle kineticss at sharp/reduced horizontal curves. The accident studies sourced by SANRAL/N3TC/DoT ‘s archives will be of import for the research survey. The possible restrictions could be the hold in recovering these accident studies and ocular appraisals will be carried out as an option . Research aims The aim of this research is to: analyse the velocity and vehicle kineticss at crisp horizontal curves ; develop drainage criterias for flow waies or deepnesss on route surfaces due to superelevation ; develop superelevation standards for steep classs on crisp horizontal curves by placing and analysing drainage jobs associated ; design safe roads from a geometric design point of view by taking factors such as clip, cost, quality, CSD into consideration ; and develop an independent package tool to help geometric interior decorators and governments in the civil technology industry. It is noted that other standards associated with the design of horizontal curves such as tangent-to-curve passages, the demand for paving broadening, and minimal curve radii would besides be considered in the development of the standards. The standards will be based on quantitative informations obtained from theoretic considerations and simulations and verified by existent field observation. The identified countries for the existent field observations will be done by going the path and monitoring of the N3. Accident statistics will be indispensable as fact-finding mention for the background of the research survey. Plan of research activities Activity The activities to set about the research proposal will be to: expand literature survey ; collate statistical informations ; get permission for design informations from confer withing technology houses and SANRAL/N3TC/DoT archives ; coordinate with SANRAL/N3TC with regard to experimental countries identified ; analyse the design guidelines ( geometric and drainage ) for rural roads ; fix the roadway mold and simulation for the assorted superelevation standards taking into consideration the drainage demands and vehicle kineticss ; Analyse the sheet flow way ( hydraulic analysis ) for the drainage demands ( perpendicular class versus route width – at sharp/reduced horizontal curves ) – the Rational Method will be used ; Investigate the CSD of route rehabilitation undertakings in relation to geometric design considerations for future route rehabilitation and major building undertakings ( It is noted that the De Beer ‘s Pass will be constructed as an option to the Van Reenen ‘s Pass ) ; Analyse research findings and observations utilizing relevant package ; Synthesize the research findings, observations and consequences ; and Write the study. Timeframe This research would take 18 months to finish. Potential end products The possible end products for the research survey will be to: Reduce or increase the superelevation values or rates, dependent on research end products, with regard to vehicle kineticss and roadway breadths ; Analyse the drainage flow waies as superelevation rates or values in relation to the drainage demands and vehicle kineticss will find the standards to be adopted for safe driver conditions ; The velocity versus vehicle kineticss analysis at crisp or decreased horizontal curves will supply suited guidelines for future rehabilitation and road-widening undertakings ; CSD findings and observations to be adopted in future route rehabilitation and major Reconstruction undertakings ; and Produce an independent package plan which will be exhaustively researched, tested and developed as a tool for geometric interior decorators and governments in the civil technology industry. This package can be integrated utilizing current technology package utilised by confer withing technology service suppliers, authorities establishments and assorted organisations will be investigated. Research results The result of this research will help design advisers in finding a much easier and safer design attack to plan rehabilitation, road-widening and major building undertakings, by placing job countries and supplying appropriate design values. The recommended standards would be documented in the concluding study and besides presented in a signifier that could be used by assorted governments. Presentations will be made at national and international conferences, seminars or symposiums associating to geometric design of roads. Workshops and talks will be conducted or presented through educational institutes, CESA and other governments in the civil technology industry. The research survey will be published as an article in transit diaries and the research sum-up will be published in several magazines. I am of the sentiment that I envisage national acclamation for the research and part of the research outputs to constructing the cognition base in South Africa.

Compare the Red Room and Farthing House looking particularly at the ways in which they build tension Essay Example For Students

Compare the Red Room and Farthing House looking particularly at the ways in which they build tension Essay The Red Room and Farthing House are both ghost stories which use the setting of unfamiliar places, The Red Room in a castle, and Farthing House in a residential nursing home for the elderly, to introduce their concept of a ghost. While The Red Room was written in an earlier period, Farthing House is more contemporary, but both refer back to the past when telling the history of the castle and Farthing House, and of its former deceased inhabitants. However, while The Red Room introduces the presence of a ghost, which the character is there to confront; in Farthing House the character meets the ghost by accident or coincidence. In The Red Room the ghost seems to be a figment of the characters imagination induced by his fear, while in Farthing House the ghost seems very realistic, despite not being set in the past, with the powerful descriptions of the look of the ghost and how she moves and cries. Both The Red Room and Farthing House are typical ghost stories. They both successfully use the surroundings of an old castle and an old house, which have long histories with deceased former inhabitants, to provide the opportunity for the places to haunted. Although in Farthing House someone dies in Cedar Room, in The Red Room someone actually dies outside the room after falling downstairs which leaves the reader less convinced the room is haunted. In Farthing House a church graveyard, another place where ghosts are traditionally supposed to appear, is visited during the day to build the atmosphere. Both stories use unfamiliar surroundings so that both the characters telling the story are ill-at-ease in rooms that are not their own and this allows for the possibility of shadows to become something more, real or imagined. Shadows and statues are personified and lurk in corners, take steps and sprang back into place, as if they were human. There is an effective use of the contrast of darkness/lightness in both stories. Ghosts are traditionally supposed to appear in the dead of night so darkness and colours such as black and grey are frequently used. For example, in The Red Room the moon is slivery and the black of the room is sombre. There is rich imagery and personification of the flickering candlelight and firelight in The Red Room which are powerfully extinguished. In Farthing House the great red sun goes down on the horizon and the dull electric lamps are like dim candlelight and the dawn is grey which sets the atmosphere in Farthing House. Both use nature, particularly the wind, and the sound of birds and trees rustling in the night which echo and introduce eerie movement/stillness and noise/peace into the story. In The Red Room the silence echoes and in Farthing House the sobs of the ghost echo. The breeze from the wind also allow the introduction of changes in temperature so that the characters shiver, feel chills and draughts and tremble. But they also become hot with panic and are soaked in sweat or pant with breathlessness. Farthing House also introduces the sense of smell with antiseptic to alert another one of the readers senses. In The Red Room, there is initial tension which builds and grows to a climax when the narrator knocks himself unconscious. Repetition is used to increase the tension with phrases such as it is your own choosing to confront the ghost and this night of all nights to do so. .u4c3974516b5b5340671d01edf72fc600 , .u4c3974516b5b5340671d01edf72fc600 .postImageUrl , .u4c3974516b5b5340671d01edf72fc600 .centered-text-area { min-height: 80px; position: relative; } .u4c3974516b5b5340671d01edf72fc600 , .u4c3974516b5b5340671d01edf72fc600:hover , .u4c3974516b5b5340671d01edf72fc600:visited , .u4c3974516b5b5340671d01edf72fc600:active { border:0!important; } .u4c3974516b5b5340671d01edf72fc600 .clearfix:after { content: ""; display: table; clear: both; } .u4c3974516b5b5340671d01edf72fc600 { 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; } .u4c3974516b5b5340671d01edf72fc600:active , .u4c3974516b5b5340671d01edf72fc600:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u4c3974516b5b5340671d01edf72fc600 .centered-text-area { width: 100%; position: relative ; } .u4c3974516b5b5340671d01edf72fc600 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u4c3974516b5b5340671d01edf72fc600 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u4c3974516b5b5340671d01edf72fc600 .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; } .u4c3974516b5b5340671d01edf72fc600:hover .ctaButton { background-color: #34495E!important; } .u4c3974516b5b5340671d01edf72fc600 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u4c3974516b5b5340671d01edf72fc600 .u4c3974516b5b5340671d01edf72fc600-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u4c3974516b5b5340671d01edf72fc600:after { content: ""; display: block; clear: both; } READ: Stereotypical kind EssayThe elderly people who introduce him to the house are not welcoming and he describes their aging deformities and presence as if they were already ghosts from the past, their very existence was spectral. The tenseness builds up when he is left to enter the long hallways alone: the long, draughty, subterranean passage was chilly and dusty, and my candle flared and made the shadows cower and quiver. Upon entering the room the tenseness is increased with the fact the candle was a little tongue of light in its vastness, that failed to pierce the opposite end of the room and the sombre reds and blacks troubled me. The young man examines ever corner of the room closely as it is unfamiliar but still finds the remoter darkness of the place too stimulating for the imagination and, by this time I was in a state of considerable nervous tension. Later after the candles are suddenly extinguished he cries with terror and dashed at the alcove in desperation and was almost frantic with horror of the coming darkness and leapt panting and dishevelled from candle to candle, which demonstrated how afraid he was of the darkness as it was letting his imagination run wild. We as readers, are almost relieved when he hits his head and become unconsciousness abruptly because he is at last free of his fear of the dark or his perception of the existence of a ghost. In Farthing House the tension is not built up to a crescendo, but builds and falls intermittently. There is a tenseness of the unknown of the location as the road narrowed to a single track, between trees, I began to feel nervous. It was very quiet, very out of the way. There is also an evocative antiseptic smell. However, the tension falls away immediately once inside the house she is warmly greeted by a friendly matron. She is also reassured by how comfortable and warm the house is, as well as by spending the evening happily reminiscing with her aunt about familiar family and childhood days. When the woman is shown unexpectedly to the Cedar Room, where she has learned an elderly resident has recently died, we expect the ghost to be related to that person. The tension rises again when she is alone in the room, she is forced to acknowledge again what had been at the back of her mind all the time, almost like having a person at my shoulder, though just out of sight. She hears the cries of a baby along the corridor but dismisses it matter-of-factly as noise from the television, and is content reading a novel and comforted by how her aunt has settled in at the home. She gets to sleep and instead of the reader anticipating a bad dream she happily dreams of the past. Then she wakes suddenly and senses a presence in the room, but dismisses it as simply her dream and turns on the lamp to confirm this only to find the most profound melancholy of spirit that had overcome me on my arrival. The story becomes the most tense when she hears the ghost crying and follows her nervously to try and help her. The next morning she feels ill-at-ease and takes a walk and ends up in the church graveyard and discovers the gravestone of a women and her baby daughter who died in 1902 and had lived at Farthing House when it was a home for women with illegitimate children. This reveals to us that the unhappy ghost was not at rest because she was looking for her daughter. We as readers are glad the story has a happy ending for the ghost, when in the present a woman takes a baby from a pram. The mother and daughter are reunited and the ghost no longer haunts the area as she is now at peace. At the beginning of The Red Room, the young man who is the narrator is very confident it would take a very tangible ghost to frighten me but progressively became less confident about confronting the non-tangible ghost who he does not see, so cannot describe unlike the ghost in Farthing House. .uee5ace31e674cceecadc609a0a4e1aef , .uee5ace31e674cceecadc609a0a4e1aef .postImageUrl , .uee5ace31e674cceecadc609a0a4e1aef .centered-text-area { min-height: 80px; position: relative; } .uee5ace31e674cceecadc609a0a4e1aef , .uee5ace31e674cceecadc609a0a4e1aef:hover , .uee5ace31e674cceecadc609a0a4e1aef:visited , .uee5ace31e674cceecadc609a0a4e1aef:active { border:0!important; } .uee5ace31e674cceecadc609a0a4e1aef .clearfix:after { content: ""; display: table; clear: both; } .uee5ace31e674cceecadc609a0a4e1aef { 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; } .uee5ace31e674cceecadc609a0a4e1aef:active , .uee5ace31e674cceecadc609a0a4e1aef:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uee5ace31e674cceecadc609a0a4e1aef .centered-text-area { width: 100%; position: relative ; } .uee5ace31e674cceecadc609a0a4e1aef .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uee5ace31e674cceecadc609a0a4e1aef .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uee5ace31e674cceecadc609a0a4e1aef .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; } .uee5ace31e674cceecadc609a0a4e1aef:hover .ctaButton { background-color: #34495E!important; } .uee5ace31e674cceecadc609a0a4e1aef .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uee5ace31e674cceecadc609a0a4e1aef .uee5ace31e674cceecadc609a0a4e1aef-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uee5ace31e674cceecadc609a0a4e1aef:after { content: ""; display: block; clear: both; } READ: Compare the presentation of your chosen character in the play with the presentation of the same character in an adaptation of the play EssayThe reader is never really certain there is a ghost and it appears that it is fear of the shadows, darkness and the wind that has gripped him. In contrast in Farthing House, the character or narrator is anxious at first because she is not certain how her aunt is settling in at the home, and added to this feels guilty that she was not looking after her aunt herself. She does not like staying in hotel rooms and is apprehensive about the presence in Cedar Room. Nevertheless, instead of stabbing frantically at the shadows on the wall and re-lighting extinguished candles to reassure herself like the other character in The Red Room, she finds the confidence to go and follow the unhappy ghost to see if she can be of assistance in finding her lost baby. The character convinces us, too, that there is a real ghost and it is not just psychological or in her dreams by vividly describing a woman in old-fashioned clothes from the past. Both stories were well written and even if there was not a real ghost in The Red Room, we as readers feel as tense as the character in the story, and in Farthing House despite being set in modern times it was realistic that there was actually a ghost. In The Red Room it was pleasing that the elderly people came to rescue the young man after he injured himself even though they did not welcome his over-confident attitude at the beginning. In Farthing House it was comforting that the main character was able to also rescue the unhappy ghost and the story ended happily, despite the death of a much-loved aunt.

Cultural Miscommunication essays

Cultural Miscommunication essays America is a country that was founded on diversity. People from all over come to America and become part of the melting pot we call home. Unfortunately, with this blending there are often misunderstandings between cultures. One area that is often misunderstood between different cultures is humor. I have lived in Orange County for five years and over that entire span I have worked in restaurants. In every restaurant I have worked in or been a patron of there have been Mexican men working as the cooks. When I first started working in restaurants I found that the front of house staff (servers, managers) tended to keep to themselves and the back of the house staff (cooks, dishwashers) did as well. Well after awhile at the last place I worked, I began to try to start bridging the gap between the two cultures. I started trying to talk to the cooks at the restaurant because I knew that most of them knew a good deal of English. After a couple of weeks I started expressing my s! ense of humor by teasing them and others that we worked with. Im not sure if making fun of people you are fond of is an American trait or a universal one but we all laughed most of the time so I stuck with what worked. My friends and I would tease each other as one of our ways of entertaining ourselves. Humor in general, certainly is a universal connection-maker. Making those connections isnt always as easy as it seems. In trying to befriend the head cook Juan at my work one night I found out that what is socially acceptable for one to joke about is strongly defined by your culture. One night about three hours into my shift on a slow night myself and another Caucasian male server were in the kitchen at my work. We had been talking to some of the cooks all night and joking around with them. We tossed minor insults back and fourth trying to make each other laugh. Later into the night the cooks started to make jokes that were homosexual in...

Digital Media - Critical Perspectives Essay Example | Topics and Well Written Essays - 5000 words - 1

Digital Media - Critical Perspectives - Essay Example What then is information society? The most common definition of information society emphasizes on technological innovation. The term refers to society where the creation, distribution and use of information are the most important aspects of economic, cultural, technological, occupational and spatial activities. An information society idea can be contrasted in societies where economic strengths lie in industrial or agrarian base. The tools of information society are computers and telecommunications as opposed to ploughs showing that information societies represent highly industrialized societies (Webster, 2005:10). The concept of information society originated from the Japanese social sciences in the early 1960s. the Japanese version of the term (joho shakai or johoka shakai) came from a conversation between Kisho Kurokawa, a famous architect and Tudao Umesao, a renowned historian and anthropologist. The first debut of the term in a written text was in a study published in 1964 by Jiro Kamishima. Since then, the term has been widely used throughout the world. Therefore, it is important to understand the term information society from the five definitions including technological, economic, occupational, spatial and cultural aspects (Lyon, 1998:3). The technological definition of information society focuses on technological innovations and the effects that the innovations have on information technologies in different sectors of society. The major aspect here is that the cost of using computers has become cheap and helped in their application in different fields. This definition provides one important aspect of information society. Technological innovations are among the most visible indicators of new times and considered as an aspect representing the concept of information society. The technological innovations include personal computers,

WEEK 2 PERCPTION KEYS Assignment Example | Topics and Well Written Essays - 750 words

WEEK 2 PERCPTION KEYS - Assignment Example Impressionist majorly used asymmetrical balance in their paintings. This majorly helped them capture a good judgment on immediacy. They made their paintings in such a manner that one item visually balanced another item perfectly (Martin& Jacobus, 2011). Symmetry has been effectively used in Edouard Manet’s painting, ‘A Bar at the Folies-Bergere. It features in few images in the painting. For example, the woman at the counter. The effect puts the lady and her job as the major aim of the painting as other objects have not been clearly brought out. Asymmetry has been effectively used in Pierre-Auguste Renoir’s painting, ‘Luncheon of the Boating Party’. He focuses more on the people at the table but still visibly shows that the boat had a number of people. The aim of the painter might have been to show what was served on tables apart from people just being in a party mood. If I was to purchase one of the paintings, I would choose Claude Monet’s Impression Sunrise. This is because of the tranquil feeling it has to the observer. The choice of color is perfect enough to create a tranquil feeling or rather a feeling of tenderness. The painting is so simple but speaks volumes. Arguments that might support the views of critics that emphasize that documentary photographers have made interesting social documents compared to works of art are that the photos majorly footage people in their usual circumstances. They are devoted to presenting the way of life of the deprived or needy people. In addition to that, documentary photography is capable of motivating and enabling people to view the humankind and what happens around us. The photos keep one informed of a lot. On the other hand, documentary photographers also have made interesting artwork compared to social documents. Documentary photography as an artwork has been criticized by many. Some have apprehended upon the emotionless and substance aspects of the

Site visit report

Site visit report [1]Site Visit Report During the site visit, I have been introduced to a numbers of scaffolds that include suspended, aluminum, mobile and etc. that are currently commonly found on construction site or factory. As stipulated under the Factories (Scaffolds) Regulations, a scaffold is any temporary structure on and from which a person performs work in any factory, construction site or shipyard or; which enables a person to obtain access to work at that location or which enables materials to be taken to any place at which such work is performed. I have observed quite a few areas of the erected scaffolds that will lead to potential hazards to the workers getting injured by working on it and in worst case might lead to scaffold collapsing. Hazard (1) Scaffold leg was sitting on red brick, uneven ground, soft soil and different height and sizes of plank was use as base support. First of all, red brick is not strong enough to take the load of the scaffold. When worker start working on the scaffold, the increase load will just cause the red brick to give way cause the scaffold to collapse. 2nd, the uneven ground and the non-uniform block which the scaffold is erected on will definitely cause the weight distribution to be concentrate more on a side than the other. In the case where the scaffold is raise higher, the whole structure might start to sway and might just topple off the ground. Control measure Sole plate of the same height and good strength is being used. It provides better base foundation for soil and ground condition that is not that good. For event when the ground selected for erecting a scaffold has to be done on a uneven ground, Adjustable base plate are being use to cater for the height different, this will ensure that the weight of the scaffold are being evenly distributed among the legs. Base plate should be made of metal so as to carry the strength to hold the standards in it. Things to note that is that the base plate should not be placed protruding out of the sole plate cause the load will not be evenly spread on the sole board. Approved scaffold contractor should be around when the scaffold are being erected as under the FACTORIES (SCAFFOLDS) REGULATION, it is the duty of them to ensure the[2]requirement are being carried out. We can also increase scaffold stability by tying it to a supported structure. Hazard (2) The working platforms are also a problem cause some of it are seen with just a single timber plank or metal decking, Firstly timber planks were observed to have crack around it, a sign it might give way when excessive load is exerted on it. Metal decking also show sign of corrosion. Due to the lack of decking or planks, the working platform become having limited space to work or walk, which might led to worker falling down. Even for platform that are closely deck or plank, materials, debris and tools were notice to been place on it as a convenient way for the workers to work and storage their thing they might need for few task to prevent walking up and down the scaffold. Sometime more than the allowable workers were working on the same bay. All this is just creating more chances for worker to trip and fall, due to the item lying on the platform and also worker have lesser space to work around. It also cause the load and weight exerted on the platform to increase which mos t properly will exceed the amount of load that the platforms are able to hold. Decking or planks are also observed to just being laid over without being secure so it has the tendency to topple. The plank and metal decking consist of different thickness and length which create mismatch along the side of the decking or plank, which will cause the worker to trip. Control measure Metal decking and timber planks are used according to the same thickness and length to ensure the platform being laid will be flushed. In the event where it need to be overlay to the other, the overlapping area should be beveled or chamfer so that it wont be at right angle to avoid tripping by the workers. Metal decking with locking device and anti-skid surface are used to firmly secure the platform to the scaffold to prevent any tipping or uplift during usage, it also lower the chances of workers skidding happened at the platform. The Housekeeping shall be carried out regularly to clear off any debris (i.e. building material, concrete etc) waste, left on the platform to ensure safer walking or working. This process is a must based on factories regulation 13 so as to reduce the hazard of working in it and additional unwanted loads is being [3]reduced. Inspection have to be carried out on the platform periodically, so that plank that [4]have start to warp or crack and metal decking that have start to corrode or stiffener that are wearing out will be removed and replaced with a new one. In the event of repairing the damage scaffold, no one shall be allowed to on it except for the approving contractor who is carrying out the task. The numbers of worker working at any one time are restricted so as to prevent exceeding the working load limit. Not more than 3 workers with tools and materials should be allowed on the platform at any one time, also the platform should be at least be 500mm width so as to create the footing space under mom regulation. Hazard (3) No ladder or stair was installed in the scaffold, which indicated no proper mean of access to the higher level or travel to another scaffold. Workers will just climb the frame of the scaffold as the mean to get to the upper level or another scaffold. This will induce a potential case of workers falling off from it as there are no protections or anything to secure them. Control measure Ladder and stair are installed for scaffold erected above 2 meters. It is also built in a way that it does not run from the bottom to the top in great height as worker will mostly falls with fatal injury, instead it is level by level. It is also built within the scaffold. When stair and ladder are available, it provide a safe and easy mean of traveling up and down, thus reduce the intention of workers climbing as a mean of traveling between the scaffold. It should be installed on a firm base that is level ground Under Regulation (17), MOM makes it a must to have ladder or stair installed for scaffold but it should never be use on a bay to gain extra height. If the access bay is part of the working platform, a trap door is to be provided. Strict controls are to be implemented to ensure the trap door remains closed while working from the platform according COP 2009 AU. Hazard (4) Scaffold platform was not built with toe-guard and guard rail and the side are being exposed to open area. Worker working on the platform have a increased chance of falling off the platform. Tools, material and debris that are placed on the platform are likely to fell down the platform due to worker will just kick over it. Workers working or walking around the bottom of the scaffold area might get injured. [5]Control measure Toe guard are built at the sides of the platform to prevent item on the platform to fall down to the[6] ground. It should be built right from the bottom and no opening so as prevent even small object to fell through it. The height should not be too low as thing will still topple off it. The standard requirement is toe guard should not be less than 90mm in height. Guardrails are installed to prevent worker from falling off from the platform when stretching out to work. Guard rail height should not be less than a meter from the platform cause installing too low would not serve the purpose of minimizing worker from falling and Minimum of 2 guardrails is to be installed on any platform with opening above 2meter according to regulation 18. Hazard (5) Some scaffold come with tag to declare it serviceability to use but some did not have tag available attached to it. So one could not tell whether it is safe for using or not. Some tags only indicate with a tick or a cross. Even if we want to check when the scaffold will be repaired or whether the serviceable tag is still valid, there is no information on the company or the approved scaffold contractor/supervisor to follow up with. Some part of the scaffold was found to be tampered. Control Measure Ensuring that every scaffold must have a tag marked clearly attached at the designated entry point so every workers using can see it clearly before using. There should be detail like the company name and the supervisor who carried out the inspection to promote ownership in the site. Contact number should also be included to cater for any issue regarding the scaffold. It also good to include the date the last inspection was done and the next inspection due date. In case that the supervisor forgot to come and inspect, worker can base on the information at the tag to determine whether the scaffold can still be use for working. Usually at site consist of workers from different country, so if able to display in a language or signboard that are easily understood would be helpful to them and thus reduced unwanted assumption. There should also be at least one designated access onto the scaffold. Lastly to add on, the ensuring of approve scaffold supervisor after every inspec tion immediately place a notice on the scaffold to certified whether it safe to be use should be enforced. Regular inspection can also identify unauthorise tampering of the component of the scaffold. [7]Hazards (6) Scaffold erectors were working without any protective gear or safety harness. Some of them wore unsuitable PPE (incorrect size of gloves, boot, helmet etc.).This will affect their griping strength their ankle protection. In this situation, they become more prone to get into accident or suffer more serious injuries when thing were to strike them. Control measure Safety boot should be provided to prevent tools or material dropping on the workers leg and also it also can act as a protection for it ankle and anti slip surface against slippery area. Helmet should be worn to prevent object falling from the above to hit the head directly. Glove can protect from burns and chemicals. When working on scaffold from 2 meter height and above, erectors should always equip themselves with safety harness with shock absorber. With the hook, the erector will able to secure them to the structure of the scaffold to prevent them from falling down. In the case where the worker fall down the platform, he would be held by the harness which will prevent him from hitting the ground and the shock absorber will minimize the chances of them injuring their spine due to the impact of the fall. Correct sizing and the appropriate type of PPE related to their work area must be issue to the workers. Hazards (7) Overlay and screening net was not secure tightly and the anchored point are tied to the scaffold. In the event of strong wind and rain, it would not serve as a protection for the workers in the building. There are also chances that it will be blown away. If it dislodged and fly out of the site, it may cause injury to the passer-by. The dragging effect of unsecured netting will cause the scaffold to experience more stress and load to it. Scaffolds might collapse as a result. Some areas of the netting are torn with holes. Debris will be able to through the net and hit the people below and more dust will be exposed out to the environment. Counter measures The net or overlay shall be tied the building structure, the top of the building structure is preferred as a anchored point. As the structure of scaffold are not designed strong enough to hold this extra load. Building structure provides better strength to counter to the wind and rain and also able to withstand load on them. Secured netting also serves to enclose the scaffold when it properly tied. Damage screening net should be [8]repaired whenever reported by workers. Netting shall be installed as close to the scaffolds as possible for the maximum effect. It should only be installed and maintains by a qualified persons. If the area always experience strong wind, more tied point shall be imposed to strengthen and secure it. It a must to fit netting or overlay for any external scaffold under MOM regulation. Hazards (8) Scaffold consist of various components which are not from the same manufacturer. Although it might look compatible to use, but often the material strength, sizes will differ. Due to different manufacturer have their own design, having different manufacturer components will usually lead installation difficulties. Forcing to install it will lead to increase wear of the component, loading capacity might be reduced. For e.g. mixing of aluminum and steel component, by using a couple which is made of steel will tend to crush the aluminum component as their strength is different. It will cause the structure to be weakened. Counter measured Always try to buy the whole set of component from the same manufacturer as their own design will often created for easy installation and able to provide the adequate strength as promised. In the event of the need to use different manufacturer component, A Professional Engineer should certified that the sizes, fixing device are compatible and most important it does not lessen the strength, stability, rigidity or suitability of the scaffold under COP 2009.au From here I end my report, the below website or file is where I took reference from www.mom.gov.sg , www.gov.pe.ca/law/regulations/pdf/O01-01-2.pdf, app.wshc.gov.sg/cms/Portals/0/Technical Advisory for Scaffolds.pdf, COP 2009 AU.
