The Ethical Treatment of Animals Essay Example for Free

The Ethical Treatment of Animals Essay Utilitarianism values equality of all interest parties. It is on the principle that when making a decision, thorough consideration on the consequent cost and benefit must be made, and it is on the basis of impartial consideration of all related interest parties that the final decision should be made. Rights-based ethics, however, value the right of individuals. It is more like individualism. It is on the principle that when making a decision, whether the right of individuals or groups will be upheld or violated should be evaluated, and it is on the basis of the benefit maximization of certain individuals or groups that the final decision should be made. The major conflict between utilitarian and rights-based moral reasoning lies in the conflict between the right of one party and the whole party. Utilitarian accepts and sometimes requires the sacrifice of the right of one individual or a small group for the well being of a bigger group. This is absolutely an absurd decision in rights-based moral reasoning. For example, in the spelunking case, a utilitarian would detonate the dynamite to save 19 lives at the sacrifice of the one stuck in the hole, while the decision made on rights-based moral reasoning will be not to detonate the dynamite. This is because according to utilitarianism the benefit of detonating the dynamite is way too higher than the cost, while in rights-based moral reasoning by detonating the dynamite the right of the one who got stuck will be violated. In my opinion, the â€Å"crime† of killing fighting dogs is acceptable in right-based moral reasoning but is unacceptable in Utilitarianism. According to the utilitarian moral reasoning, the sacrifice of the interest of a smaller group is acceptable for the good of a bigger group. However, in this case, if dogs count as one group, the sacrifice of the poorly performing dogs is no necessary requirement of the survival of other fighting dogs, nor of the livelihood of any human group. If they do not count as one group , the people who love dogs must count, the behavior of killing dogs would hurt their feelings, so when impartial consideration of all related interest parties is made, the cost of letting these dogs live must be less than the benefit. Therefore, the behavior of killing dogs is against the Utilitarianism values. Rights-based ethics, nevertheless, defends the right of any individual or group, and the  duty is not taken into consideration. Just like the defender’s said, the dogs are Vick’s property, and he can do what he like to them, despite the fact that he also has the duty to take good care of them. Even though there is no doubt the right to live is one of the most fundamental rights of any creature, the right-based moral reasoning are for the right of human, dogs, sadly, are not included. So when this right-based moral system is at work, any kind of disposal of one’s property is acceptable. That is why I say the â€Å"crime† of Vick the â€Å"crime† of killing fighting dogs is acceptable in right-based moral reasoning but is unacceptable in Utilitarianism.

Case study of bipolar disorder sufferer

Case study of bipolar disorder sufferer People with bipolar disorder have extreme mood swings (symptoms). They can go from feeling as if they are on top of the world, hyperactive, creative, and grandiose- mania to feeling very sad, despairing, helpless, worthless, and hopeless -depression. This disease is called bipolar disorder because the mood of a person with bipolar disorder can alternate between two completely opposite poles, euphoric happiness and extreme sadness. The extremes of mood usually occur in cycles, in between these mood swings, people with bipolar disorder are able to function normally, hold a job, and have a normal family life. The episodes of mood swings tend to become closer together with age. When a person is in the grip of this disease, chaos can occur. Bipolar disorder can cause major disruption of family and finances, loss of job, and marital problems. In Jims case he becomes completely dependant of his parents. Because of the extreme and risky behaviour that goes with bipolar disorder, it is very important that the disorder be identified. With proper and early diagnosis, this mental condition can be treated. Bipolar disorder is a long-term illness that will require proper management for the duration of a persons life. Jim is in his mid fifths and he still live with his parents, whose are in their late seventies. He is the only child and his parents overprotect him over the years owing to that he became completely de-skilled, dis-empowered and total dependant. He is not able to negotiate and he was not included in family discussions to show his opinion. The only way that he has to show that he is not happy is by screaming and crying. Jim definitely also suffers from Eternal child syndrome, also know as Peter Pan syndrome, and is to blame his parents who been treated him like a child all his life. Psychologists warn that overprotective parents can be responsible for this disorder as this prevents them from developing necessary skills to confront life. Jim chronologically grows older but in truth he has not grown up. Like Peter Pan he breaks societal norms to serve their own purposes and do not care much for the feelings and rights of his parents. He wants all the power but is not willing to share the responsibilities, not ready to sacrifice and reject moral structures which are part of mature adulthood. As the World Health Organization has not yet recognized Peter Pan Syndrome as a psychological disorder, the syndrome is not currently considered a psychopathology. Psychologists make a clear distinction between Peter Pan Syndrome and other, more serious, mental conditions involving adults who behave as children both emotionally and mentally. This is because it is often found that people suffering from Peter Pan Syndrome are mentally fully developed adults who often carry professional activities requiring strong intellectual skills. This syndrome is often associated with narcissism, although not in a negative way, self-centered sense. They are attracted to introspection in an attempt to find that imaginative comfort inside their own minds. On a positive sense this characteristic is seen as being in touch with the unbridled imaginational freedom of childhood. While succumbing to the prescribed order of things, most people forget all that they knew as an idealistic child, the eternal child is able to draw from their own raw, creative energy to remind us of how colorful life really is. Men suffering from the Peter Pan Syndrome display the following traits in their relationship with parents: Are obsessed with their mothers Have estranged relationship with the father They believe that it is not possible to obtain the fathers love and approval They have difficulty interacting with figures of authority Are not mature emotionally Exhibit silly behavior Hide their inner insecurity with macho attitude Males diagnosed with having this syndrome were found to exhibit the following psychological traits: Either exaggerated or paralyzed emotions Anger taking extreme form of rage Joy turning into hysteria Disappointment grows and develops into depression or self-pity As a result males diagnosed with this syndrome find it difficult to express love, refuse to share feelings, feel guilty and have difficulty relaxing. Men with Peter Pan Syndrome find it difficult to make genuine friends and as a result feel desperately alone. They dont feel sorry for inappropriate actions but blame others for their shortcoming. Males diagnosed with having this syndrome were found to exhibit the following psychological traits: Either exaggerated or paralyzed emotions Anger taking extreme form of rage Joy turning into hysteria Disappointment grows and develops into depression or self-pity As a result males diagnosed with this syndrome find it difficult to express love, refuse to share feelings, feel guilty and have difficulty relaxing and find difficult to make genuine friends and as a result feel desperately alone. This has a huge impact in Jims parents who are finding difficult to cope with all this matters, especially in during the winter. They are gradually worried about their ability to cope and what will happen with Jim when they die. They might feel a host of emotions: distress, vulnerability, anger, guilt and, surely they probably are exhausted. As an informal carer for several years, Jims parents revolved all their life on him, they devoted all their live to him. Like Jim who does not has friends (apart form his parents friends), some people that experienced the same condition as him generally have a very limited social network as well, and normally the people that they interact are mainly informal careers. 4 First of all Jims parents have take him to GP and if he is diagnosed with bipolar disorder, the GP will refer him to a psychiatrist (a medically qualified mental health specialist), psychotherapist and /or CPN. At his appointment he will be given an assessment. The psychiatrist will ask him a number of questions to determine whether or not he has bipolar disorder and, if he has, what treatments will be most suitable for you. He will be asked about his symptoms and when he first experienced them. The psychiatrist will also ask him, about how he, usually feel leading up to, and during, an episode of mania, or depression, and whether he has had thoughts about harming yourself or others. The psychiatrist will also want to find out about his medical background and his family history in order to determine whether any of your relatives has had bipolar disorder. If someone else in his family had the condition, the psychiatrist may wish to talk to them. After the assessment the psychiatrist will prescribe the right drugs and refer him to a psychotherapist. Psychotherapists work with individuals, couples, families and groups to help them overcome a range of psychological and emotional issues. With the client as an active participant, psychotherapists use personal treatment plans and a variety of non-medical-based treatments to: address the clients thought processes, feelings and behaviour; understand inner conflicts; find new ways to deal with, and alleviate, distress They take a variety of approaches according to the theoretical models they adopt and the therapy they practice. These talking therapies include: cognitive behavioural therapies; psychoanalytic and psychodynamic therapies; humanistic and integrative psychotherapies; systemic therapies; hypno-psychotherapy; experiential constructivist therapies. Community Psychiatric nurses (CPNs) would be helpful to Jim as they can visit him in his new house and provide him support through the difficult periods of his illness, they also will see him when is well to check that everything is okay and be the first point of contact if he becomes unwell again. The CPN will help Jim with his medication and make sure that he understands what he should be taking and when. They also help patients family (in this case Jims parents) and careers understand and cope with the illness. Jim and his parents would benefit of Occupational therapists (OTs) as well. An occupational therapist can have many different roles. They will help Jim and his parents (when he moves out of his parents house) to adapt to the new environment and to cope with their daily life .OTs may work in hospitals or in the community. They supervise and assess a persons ability to look after themselves, e.g. self-care, cooking and housework, I would like point out that Jim does not know how to cook, clean or do his laundry. . OTs work with both individuals and groups. They can set goals for individuals with depression to encourage them to achieve more than they have been able to do while ill. They might get patients involved in specific job-related training schemes to improve their decision making and planning about the future. Group work is often aimed at increasing peoples social interactions. OTs may use many different types of therapy on an individual or group basis, including cognitive behavi oural therapy and art and music therapy. They may also be involved in providing relaxation training to patients referred to them by the mental health team or GPs. Social workers are employed by social services rather than the health service. However, most mental health social workers are based in multidisciplinary community mental health teams. Social workers may see patients referred to the team by GPs. They are likely to be involved if patients have social problems, such as housing, money and work. They may provide counselling and advice or more specific therapies. They may control access to some services such as day centres, respite care, residential care and other community support services, eg home helps. A social worker will also provide Jim a supported tenancy service which will help and teach him how to gain his independence and improve his quality of life.

Causes of Brick Deterioration and Decay in Buildings

Causes of Brick Deterioration and Decay in Buildings Introduction Most parts of the building are built from the brick. Nowadays, the brickwork defects ware commonly founded in building. The problem was getting more serious and serious. Seriously of the brickwork defects may cause a lot of problems to the occupants. The main problem encountered in building with a traditional outside bearing wall of brickwork and concrete inside bearing structure is caused by differences in the temperature and moisture-induced movement. Crack maybe be discovered in walls and solutions have to be found. (L.G.W.Verhoef, 2001) Brickwork defect occurs in building has a variety of reasons. This is perhaps not surprising when one considers the wide range of differences bricks and technique in construction of building, differences in the construction sites and the varied occupational or owner used of the completed building. Brickwork will deteriorate and decay if not properly maintained. Such deterioration can be caused by a number of factors and can take various forms. The main signs that brickwork is suffering are surface growth and staining, efflorescence, loosed brick becoming dislodged, crack appears throw the bricks or mortar and etc (Moses Jenkins, 2007). In this sub chapter, the different types of the brickwork defect will be determined. This chapter gave an overview of various types of the brickwork defects and understanding the brickwork defects. To identify the different types of the brickwork defects will make easily for the occupants or owners to find out the causes of the defects and take the suitable remedies method in the right way. Define bricks Brick is the materials that commonly use to build the buildings wall. Clay bricks are the most common brick type. It is made from the sand and clay and uniformly burnt at temperatures between 800 °C and 1200 °C. Surface finishes are sometimes applied e.g. glazed bricks. Glazed bricks are still being produced in quantity and can be obtained from a major English brick manufacturer and supplier. Calcium Silicate bricks is manufactured from sand-lime (calcium silicate). The bricks are pressed under great pressure and steamed in an autoclave. The bricks are smooth, fine textured and light in colour. The brick colour is produced from material source, composition and firing temperature. The size of bricks over time has changed considerably. Some early medieval bricks were 13 inches by 6 inches by 2 inches. By the late 15th century a brick 9.5 inches by 4.5 inches by 2 inches became the norm and a charter in 1571 stipulated 9 inches by 4.5 inches by 2.25 inches. By the 18th century, 8.25 inches by 4 inches by 2.5 inches brick was introduced. Modern bricks are 8.5 inches by 4 inches by 2.5 inches which following metrication translated to 215mm by 102.5mm by 65mm. Modern bricks is the brick that most of the building using in nowadays. Defect of size Oversized bricks are caused by poor material selection and preparation or underfiring. Under size bricks are caused mainly by poor material preparation, faulty moulds and overfiring. Defect of shape The causes of these defects are many. These are including poor preparation of moulds or moulding technique, faults in stacking, rough handling and uneven drying. If the bricks are considerably over burnt, incipient fusion takes place and the bricks, called burrs, come out of the kiln or clamp stuck together. Burrs are suitable only for hardcore purposes. Defects of body Faults in the raw material body can give rise to defects such as cracking, bloating and laminations. Cracking and warping of bricks, causing incipient weakness, maybe due to exposure of green bricks to direct sunlight or rapid drying winds. Similar effects will be produced by putting green bricks into the kiln too soon. Large cracks maybe caused by rain getting onto hot bricks. Defect of Appearance These defects are caused primarily by faulty wires in the case of wire-cut bricks. Dark spots are caused by the presence of unevenly distributed iron sulphide in the clay. Brick wall settlement Any movement in a structural  brick wall which risks having broken the bond courses in the wall, and any movement in a  brick veneer wall which has broken or loosened the connections between the veneers to the underlying structure are potentially dangerous and risk collapsing masonry. Bulging brick wall This is likely to be a bond-brick or bond-course failure. This defect is potentially extremely dangerous and must be very urgent to take action. If not, it can causes the building suddenly collapse. Cracks and Bulges in brick walls Frost and earth loading can push a below-grade brick foundation wall inwards. The wall is often bulged inwards as well as showing horizontal and step cracking and loose bricks over the bulged area. The damage occurs from slightly above ground level to roughly the frost line. Cracks and loose bricks Normally, crack and loose bricks are cause by frost, settlement, expansion, diagonal and stair-stepped. Those defects often happen at building corners where roof spillage is concentrated. Loose bricks and missing or lost mortar This is the movement where mortar is severely washed-out by roof spillage or other water movement against the foundation. Loose and lost bricks may also occur where wood blocks, originally set into a wall to permit nailing of interior components, is damaged by insects or decay. Similarly, if wood joists are damaged and bend excessively or collapse (insect damage, rot, fire) the collapsing joist can, as its in-wall end moves, damage the foundation or building wall. Fire cuts on wood joists in brick walls were intended to minimize this damage source by angling the end of the joist where it was set into the wall pocket. Sand-blasted bricks   Which have been cleaned of old paint, algae, or stains using high pressure sand blasting or possibly even very high pressure water blasting can be permanently damaged by loss of the harder surface of the bricks which had been provided by their original firing. Once the softer internal brick has been exposed, the bricks will be more inclined to absorb water and to suffer water and frost damage. Sandblasting brick is considered a poor practice in building renovation and maintenance. Spalling bricks Spalling is caused by water and frost, such as water leaking into a brick structure at any entry point: a crack, a brick which has lost its hard surface, or at openings by window and door penetrations. But beware about caulking brick. Exfoliating-rust damage to brick   Masonry wall occur these defects when brick walls have been improperly caulked where caulking should have been omitted. The most common example of this defect is the damage that occurs to a brick wall when a steel lintel over a window or door is caulked tightly between the brick and the steel. Moisture penetrating the brick wall through cracks or mortar joints is trapped around the steel lintel. Rust developing on steel lintels has tremendous lifting power as the rusting exfoliating metal expands, sufficient to crack and damage bricks around lintel. Improper repair mortar  on brickwork During repair work, tuck pointing bricks, or re-pointing bricks can cause surface spalling of bricks if the mason uses a too hard mortar with high portland content mortar on soft brick in a climate exposed to freezing weather. The high portland content means that the mortar will be not only harder, but more waterproof than the surrounding brick. Water trapped around the hard mortar can freeze leading to surface spalling of the bricks. This is particularly likely to be seen when a wall has been tuck pointed using hard high-portland mortar where originally a soft high-lime mortar was used and where the original bricks were soft. Salts on brickwork Salts are a major cause of deterioration. Salt can enter bricks through contaminated water ingress. In coastal areas salt can come from the sea and, in winter, the nearby application of road salt is a constant threat. Salt is damaging because it creates a steady expansion of crystals within the bricks. This can eventually force the structure of the brick apart. The source of salt can occur from within the bricks themselves or from the application of contaminated mortars or renders. Brick lined chimney flues are also vulnerable as sulphates can be introduced when flu gasses condense. This is a common defect where a chimney has been sealed without adequate ventilation. Efflorescence on brickwork Efflorescence appears as a white powdery deposit on the brick. It is a phenomenon that soluble slats dissolved in water are carried, deposited and gradually accumulated on brick surfaces to form an unsightly scum. Without water efflorescence cannot occur. The soluble salts may be originated from the raw material of bricks. But in most cases, efflorescence is caused by salts from the external sources such as ground water, contaminated atmosphere, mortar ingredients and other materials in contacts with the bricks. To minimize the risk (it can never be completely avoided in brickwork exposed to weathering) the building detail should be designed, as far as is possible, to avoid saturation. In other words good overhangs, copings and sills with drips all need to be considered. Efflorescence can be helped on its way by sponging down the wall with clean water (avoiding substantial wetting) or dry brushing with soft brushes. Any other treatment should be avoided as it may disfigure the bricks .   Frost Attack on brickwork Frost attack often occurs when very cold weather immediately follows a very wet spell. When porous materials become saturated and the temperature drops below freezing the formation of ice causes stresses which some bricks cannot be resist and cracking or spalling occurs. Clay bricks are classified as frost resistant, moderately frost resistant, and not frost resistant. Calcium silicate bricks are not generally at risk although it is wise to specify bricks with a compressive strength. Thermal movement on brickwork Every materials expand or contracts as the temperature of the material changes, typically expanding as its temperature increases and contracting as its temperature decreases. Different materials expand and contract at different rates when they undergo similar changes in their temperatures. Brick veneer can expand and contract approximately. When determine the expansion or contraction of a brick veneer, it is important to remember the effects of the sun on materials. The energy from the suns rays raises the temperature of a material well above the air temperature. On a day when the air temperature is 32 ° F, the energy from the sun can raise a walls temperature to above 100 ° F Thermal expansion failures in structural or veneer brick walls A separate factor that can cause very large movements and extensive damage to brick structures or brick veneer walls is the thermal expansion which occurs across a long or tall brick wall when that wall is heated by sun exposure. The photographs show significant thermal expansion damage in a long brick structure. Significant breaks and gaps  at vertical brick mortar joints due to thermal expansion and perhaps some frost and water damage. Photograph of thermal expansion damage to a brick wallFigure1: Significant breaks Horizontal sliding breaks  in brick mortar joints,  exposing reinforcing wire to rust, exfoliation, and additional damage from those forces as the exfoliating wire produced still more pressure on the mortar joint.

Photograph of thermal expansion damage to a brick wallFigure3: Step cracking Cracks and broken bricks at the intersections of brick walls and openings. Photograph of thermal expansion damage to a brick wallFigure 4: Cracks and broken bricks (InspectApedia, 2007) Moisture movement on brickwork Moisture affects all porous masonry materials, including brick, mortar and concrete masonry units but in very different ways. These effects must be considered when a combination of these materials is used, such as when brick rests on a concrete foundation, brick veneer units are used with block back up, and when brick and architectural concrete products are used in the same wythe bands of precast concrete or architectural concrete block in a brick veneer. After their initial mixing or casting, mortar, poured-in-place concrete and concrete masonry units shrink as the curing of the Portland cement proceeds. This is an unavoidable consequence of the curing of concrete products and is accommodated in design. Sulphate attack on brickwork Most ordinary clay bricks contain sulphates of sodium, magnesium or calcium. These salts are soluble in water in water, calcium sulphate being less soluble than the other two. Normally, these sulphates are seen as the harmless efflorescence which affect appearance only and need simply to be brushed away. In theory, most brick walls with mortars based on OPC (Ordinary Portland Cement) are liable to sulphate attack. The most vulnerable walls are earth-retaining walls and parapet walls but sulphate attack is a problem also on rendered, and on facing brickwork. On rendered brickwork, sulphate attack is manifested by cracking of the rendering, the cracks being mainly horizontal and corresponding to the mortar joints below. The rendering may adhere quite well to the bricks early in the attack but areas are likely to become detached as the expansion of the underlying brickwork causes severance of the bond between the two material. (H.J.Eldridge,B.Sc.1976) Lime staining on brickwork Lime staining occurs when calcium hydroxide is deposited on the face of brickwork. Lime staining will quickly absorbs carbon dioxide from the air and becomes calcium carbonate. It is virtually insoluble and can only be removed by expert and costly treatment. The calcium hydroxide can come from three main sources: calcium hydroxide caused by the hydration of Portland cement from hydrated lime added to mortar from brickwork in contact with wet concrete Porosity on brick Porosity is an important characteristic of brick. In contrast to other moulded or pre-cast building materials, the porosity of brick is attributed to its fine capillaries. By virtue of the capillary effect, the rate of moisture transport in the brick is ten times faster than in other building materials. Moisture is released during day-time and re-absorbed during night-time. The ability to release and re-absorb moisture by capillary effect is one of the most useful properties of brick that helps to regulate the temperature and humidity of atmosphere in a building. This distinctive property makes brick an admirable building material, particularly suitable for buildings in the tropics. On the other hand, all porous materials are susceptible to chemical attacks and liable to contamination from weathering agents like rain, running water and polluted air. Crack in brick faces/firecracks The finished appearance of clay brick can vary greatly, this is because dependant on clay and the manufacturing process. Some products contain cracks of varying degree (sometimes referred to as firecracks) as an inherent feature. Firecracks are usually visible on the product as delivered. However, firecracks can be masked by the texture and surface sands used in the manufacturing process becoming visible after bricks are laid as a result of natural weathering of exposed brickwork. Dampness of the brick wall More or less permanent dampness showing more clearly on the internal wall surface from ground level up to a height of about 750mm, but may be higher in severe cases or if the outer face is covered with a non-porous finish. The decorations may be damp, blistered or discoloured, or, if dry, may have been pushed off the wall by a film or salts which will often be seen as a fluffy crystalline growth. The possible causes of dampness in the brick wall are lack of dpc (damp proof course), by-passing of the dpc, Failure of the dpc material. Brick growth and expansion gaps in brickwork Bricks undergo long-term permanent expansion over time. This expansion continues for the life of the brick, but the majority of the growth occurs early in its life. Most general purpose bricks have a coefficient of expansion in the range of 0.5-1.5mm/m (millimeters per meter) over fifteen years. Designers can use the values of the coefficient of expansion to accommodate for the growth of bricks by the size and spacing of the control joints. The provision of control gaps or articulation joints between parts of the structure during construction will accommodate movements within the structure over time. Numerous sources of movement exist and include: The change in size of building materials with temperature, loading conditions and moisture content The differential change in size of building materials (for example, cement products shrink over time, whilst clay bricks expand slowly over time) Foundation and footings movement Frame movement Frame shortening Temperature movement Internal horizontal and vertical movement Causes of the brickwork defects Introduction: Brickworks are used primarily in the construction of walls. To construct the brick wall required many skills, design, experience, selection of material, and technique. Lack of all expertise may cause the brickwork defects or failure of the building. The defects that occur in brickwork maybe the result of inherent faults, deficiencies in production, design, materials or workmanship, and attack by environmental agents. After the brickwork has been constructed, it maybe meets of various requirements, climate, loading, and occupational in use. It is not surprising that defects happened or occurs frequently. In this sub chapter, the causes of the brickwork defects will be list out. To find out the actual causes of the brickwork defects will be easily for the occupational to take the right remedies immediately and reduces the brickwork defects happen. Selection of bricks The choice of bricks is often influenced by the price but the quality required must also be carefully considered in order to avoid defects developing during the service life of the material. Therefore, the selection of suitable bricks for any particular purpose has often to be a trade-off between appearance and durability requirements on the one hand, and cost on the other. This is not always possible to assess the quality of bricks by the colour, variability of colour of bricks of the same source and method of production can often be an indication of strength and durability variations. Storage of bricks Bricks on site are rarely kept under adequate cover. Defects in the bricks resulting from the lack of adequate protection on the site are rarely apparent before use. However, bad weather conditions can be detrimental to bricks in that saturation by rain can be responsible for both subsequent efflorescence and decoration defects. Soluble Salts in Bricks Under burnt bricks contain a high salt content. The salts come from the raw clay from which the bricks are made, or are formed in the burning process. Most clay bricks contain some soluble salts, but the types and amounts vary appreciably. The effect of the soluble salts on both efflorescence and the more serious problem of disintegration of bricks themselves are largely governed by the strength and pores structure of the bricks. Sulphate attack Sulphates are salts which are naturally present in industrial waste, gypsum product, clay bricks, flue condensates and in some ground waters. In persistently damp conditions, sulphate will react slowly with tricalcium aluminate forming a compound called calcium sulphoaluminate. This reaction causes the cement mortar or render of the brickwork to expend and eventually disintegrate. Solar Radiation While drying out of soil by trees is the most common reason for cracking in brickwork, some clay are also very susceptible to drying out by direct solar radiation. The northern facing wall is the most likely to be affected and stepped diagonal cracking is the most common symptom, usually occurring at the north east and north west corner of the building. (Greg Loveder, 2000) Migration of moisture The movement of moisture beneath a building can produce the phenomenon known as long term dome and saucer effect. The dome effect is a slow heaving of the soil caused by movement of moisture from the perimeter of the house to its centre, and the saucer effect is moisture moving in the opposite direction, from the centre towards the perimeter. The dome effect causes the walls to tilt outwards and the restraining influence of the roof produces horizontal cracks on the outside wall. These will be wider on the outside surface rather than the inner. Planting of tree Some of the brickwork defects may cause by big trees roots that plant nearby the building area. When planning to plant trees, the idea to be considering is the strength of the footings under the house. If lack of strength, the roots of the trees maybe grow into the ground under the building and cause the brick wall settlement and cracking. Uneven settlement of foundations Where a particular heavy load is placed on the foundation such as a large column, movement may occur as moisture is squeezed out of the soil or the soil readjusts itself. This consolidation will stop when the soil has finally compacted enough to support the load. Brick wall or masonry wall may crack which may result from movement during compaction. Excessive vibration Damage caused by vibration from earth tremors, heavy traffic or pile driving is fairly rare, however if the vibration is great enough to actually cause the foundation to move, brickwork cracking or defect can occur. The crack will show up irregularly if the sources of the vibration cannot be removed. (Greg Loveder, 2000) Additional building Building an addition building onto a house or add more storey of houses can impose a load intensity on the soil different that which is there already and so cause differential settlement. Even if the loading intensities are similar, the difference in time between when the two settlements occurred can be enough to create the brick wall cracks. Approach of design Design of brick wall is very important. The designer must have the knowledge about the brick experience in chosen the types of brick to be used. The designer must be fully aware of the clients needs. Defects often occur because of a lack of understanding of the different types of bricks and the method of construct the brick wall. Lack experience of worker Workers in the masonry construction is not in strict accordance with the construction and standards, masonry mortar is not full, especially in vertical mortar joints are not full, and even produce dense seam, seam permeability. In addition, the dry brick on the wall, mortar in the brick water was absorbed, causing low strength of mortar, brick and mortar separation, so that the overall stiffness of masonry fell, gray mortar joints crack. Overloading Cracks of brickwork may result from overloading of the ground on which the building rests, or of the building itself or parts of it. Releasing the load does not necessary allow the masonry wall to revert to its original state since the overloading may have been partially accommodated by a permanent compaction of the bricks. The forces responsible for the overloading may be of external origin, such as excessive wind, or may be internal, such as those arising from the installation of excessively heavy equipment for which the masonry wall was not designed. A change of occupational may have same results. Lack of maintenance Maintenance must be taken for all the building to minimize the cost of repair work for seriously defects happen. Lack of maintenance will make a small cracks or defects on brickwork change to more serious and serious. Improper soil analysis and preparation When a builder chooses an area of land to build on, it is important to do some sort of soil analysis and preparation. The analysis will provide the developer and/or builder with enough information to choose the adequate soil preparation and construction strategy that should be used to develop the land. Improper soil analysis and preparations can be very damaging to a housing development. For example, a builder can discover that the land soil is made up of expansive soil. If this is the case, houses need to have a foundation that will be able to support the changing pressure and consistency of the soil. This is because expansive soil will swell when wet and then shrink once it dries. If one builds on this type of soil and is not aware of it, there will inevitably be issues to handle. There will be crack in the brick wall or masonry wall. The repair of this is very costly and very intrusive. Unfortunately, the reality is improper soil analysis and preparations happen all the time. Negligence of construction Negligent construction is an unfortunately common occurrence. A builder has to be very careful when choosing a contractor or subcontractor. A builder will sometimes use one contactor for various projects. A contractor may have skills to install floor tiles but not the know how to build a brick wall. The responsibility can fall on several parties when there is a defect, and thats up to your attorney to determine. Movement of the ground Mining subsidence, landslips, earthquakes, or moisture changes of shrinkable clay soil may cause the movement of the ground. The brick wall of the building will be crack because the wall of building has become displaced from the rest without any change in actual size of the materials. In theory, this is possible to reconnect the displace parts to bring the building back to its original condition but in practice this seldom can be done. Acid rain Acid rain is precipitation that is much more acidic than normal rainfall, and the acid rain is usually caused by pollution such as sulfur and nitrogen emissions. Several different mechanisms are operant in the deterioration of brick masonry through the action of acid rain. The bricks are susceptible to acid rain through the selective dissolution of their glassy phase. The mortar is affected mainly by the reaction of the calcareous components. The soluble salts resulting from these reactions, in solution with rain water or condensed moisture, will migrate through the porous matrix of the masonry. In the places where the water evaporates the salts will be deposited. Repeated dissolution and re-crystallization of these salts leads to the mechanical disruption of the masonry structure. Since the salts will concentrate in the more porous material, either the brick or the mortar will be more seriously affected, depending on their relative porosity. Environment Two aspects of the environment have been considerably which is wind and temperature. This is because they cause loading to be applied to the structure. The strong wind may cause the brick wall or the whole building move, this may cause cracking to the part of the building. The high temperature applied to the brickwork may cause spalling and brick prolong to high temperature can lead to surface vitrification. (A.M.Swoden, 1990) Remedies method of the brickwork defects in building Introduction: As known early, brickwork is one of the largest parts of most of the building. The strength, stability, and durability of brickwork are very important. If lack of all those factor, the brick wall or masonry wall maybe fall down or collapse suddenly. If the brickwork occurs any cracking or defects, the right method of remedies must be taken immediately. This is to ensure that the occupational or owner use the building under safety and healthy purposes. Brickwork will deteriorate and decay if not properly maintained. Such deterioration can be caused by a number of factors and can take various forms. The main signs that brickwork is suffering are surface growth and staining, efflorescence, loosed brick becoming dislodged, crack appears throw the bricks or mortar and etc. So, the right remedy must be taken to ensure the brickwork do not decay and deteriorate. (Moses Jenkins, 2007) In this sub chapter, the remedies method for various types of defects will be list out. This is to avoid the brickwork defect getting serious in building in construction industry. The defects of brickwork must be repair immediately, if not the defects will be more serious. For example, cracking can be due to expansion or shrinkage the clay brickwork itself. Remedies of efflorescence Efflorescence can be minimized by laying dry bricks and by speeding up the drying process after the bricks have been laid by providing good ventilation. The salts that cause efflorescence are soluble in water. Hosing with water will cause the salts to dissolve and be re-absorbed into the brickwork, and then reappear when the brick wall dries out again. Acid or alkaline treatments are not recommended as they increase the salt content of the wall. The best method is simply brush off the deposit with a stiff dry bristle brush after the wall has dried out. Then sponge the surface with a damp synthetic chamois or high suction sponge. Use very little water and rinse sponge frequently in fresh water. Remedies of sulphate attack The effects of sulphate attack manifest themselves as expansion of the jointing mortar. On rendered walls the signs are horizontal cracking of the rendering with portions falling off. Advanced stages of attack may make the structure unsafe. When rebuilding is necessary, the bricks use should be of low sulphate content and the mortar should be of a mix of 1:1:6 sulphate-resistance Portland cement: hydrated lime: sand. In addition, care should be taken to exclude all conditions of dampness. On rendered walls, the rendering should be removed and the brickwork allowed to dry before reapplying a weaker mix of sulphate-resistance cement, lime and sand. Tackling Decay Where decay has occurred, take action to rectify the damage will be necessary before this leads to greater problems. The use of chemical treatments to stabilize brick should only be considered with extreme caution. Whilst the defects may be effective initially, there has been insufficient research carried out on the possible long term damage such treatments could have. Chemical sealants can trap moisture within the brick just as effectively as the claims to keep water out. Cleaning Cleaning soiled brick buildings should be undertaken carefully. In the past, the use of inappropriate cleaning techniques has resulted in considerable damage being done. If considered essential small scale tests should be employed to assess the effectiveness and likely damage which could be caused before any large scale work is carried out. There are some guides when doing the cleaning works:- Do not re-clean brickwork with the same chemicals unless recommended by the cleani

The Search for Self and Identity in Jack Kerouac’s On The Road :: On The Road essays

Quest for Identity in On the Road In Jack Kerouac's novel On the Road, the author tries to convey to the audience that everybody is naturally dishonest and morally deceitful. Morals are defined by one's religion, the laws of the country, or some combination of the two. One's identity captures and plays out that individual’s moral. My morals follow the Christian beliefs, Texas state laws, and the laws of the United States. Although one's own morals can change, basic things such as stealing and murder are wrong and illegal by federal law. Numerous characters performed many acts proving this point such as Montana Slim, who says in order to get money, follow a man down an alley and rob him, or Dean, who never feels remorse for beating Mary Lou after a fight. These along with other characters display such actions that show that everyone is morally deceitful. In Part 1, Chapter 4, Sal tells Montana Slim that he only has enough money to buy some whiskey. Slim says to Sal, "I know where you can get some." "Where?" "Anywhere. You can always folly a man down an alley, can't you? ...I ain't beyond doing it when I really need some dough." (27) At this early point in the novel, Sal is still figuring out who he is and what life is like on the road. He seems like a young naive schoolboy being bullied by an older, wiser kid. Slim knows what he is talking about because he has been on the road for some time now. He has probably robbed quite a few people throughout his experience on the road. This act is, by law, wrong and dishonest. In Part 2, chapter 6, while Dean, Mary Lou, Ed Dunkel, and Sal stopped at a gas station on the way to New Orleans, Dunkel casually steals three packs of cigarettes. The way the narrator says it is that he stole them without even trying. He then justifies it by saying that they were fresh out (139). The language used is just so "non-chalant," as if stealing was no big deal. Stealing, like robbing, is illegal and morally wrong. The part that is most disturbing is that Dunkel feels that stealing cigarettes is okay, that it is necessary for survival just like food or water. Stealing food or water in order to survive can be justified, but not cigarettes.

The analysis conducted shows the importance of quantity production variability on the profit maximizing verge. A range of values is presented by four Regional Sales Managers; each region includes the minimum, most likely and maximum sales values of a random variable. The sample data is described as simple, limited, and somewhat scarce; therefore, given the grade of uncertainty, the most appropriate and suitable distribution to use is the Triangular distribution. The Monte Carlo Simulation from Microsoft Excel @Risk, will calculate â€Å"a model output value many times with different input values. The purpose is to get a complete range of all possible scenerios. †1 For the Region 1 the demand is generated from (3000, 4000, 8000) with a mean of 5000. One point of interest in the data is the variability of the values. According to the parameters of this data the coefficient of variability is 22%. The graph is right skewed, as we see the mean (5000) is right to the median (4875), and the median is right to the mode (4000); its peak represents the most likely value (4000). According to the input the total demand average generated for this region is 5000 jackets. For the Region 2 the demand is generated from (2000, 4000, 5000) with a mean of 3667. One point of interest in the data is the variability of the values. According to the parameters of this data the coefficient of variability is 17%. The graph is left skewed, as we see the mean (3667) is relatively close, but left to the median (3717), and the median is also close, and left to the mode (4013); its peak represents the most likely value (4000). According to the input the total demand average generated for this region is 3667 jackets. For the Region 3 the demand is generated from (1500, 2000, 3500) with a mean of 2333. One point of interest in the data is the variability of the values. According to the parameters of this data the coefficient of variability is 18%. The graph is left skewed, as we see the mean (2,333) is left to the median (2269), and the median left to the mode (2242); its peak represents the most likely value (2000). According to the input the total demand average generated for this region is 2333 jackets. For the Region 4 the demand is generated from (500, 1000, 1500) with a mean of 1000. One point of interest in the data is the variability of the values. According to the parameters of this data the coefficient of variability is 20%. The graph perfectly symmetric, the peak represents the most likely value (1000). According to the input the total demand average generated for this region is 1000 jackets. When the four Regional demands are summarize (5000, 3667, 2333, 1000) we totalize an estimate value of 12000 jackets. The four Regions have different means, standard deviation; the tendencies of the values are they decrease from Region 1 to Region 4. Beside the values provided by the four Regional Sales Managers, 12 Egress employees have independently estimated demand for the upcoming season. Using the same program described above, the sample data generated a mean of 11750, standard deviation 3678, and an IQR of 5039. The best distribution fit for the sample appears to be triangular. If compared to the Regional Manager’s demand, the mean generated from the employ ees’ estimate (11750) is very close to the total demand estimated by the triangular distribution (12000) from the manager’s data. The most appealing option, between the two demand estimates, is the Regional Manager’s demand as it leads to the possibility of generating triangular distribution estimates, easy to understand and visualize any effect of any changes, which will result in positive decision making. There are three different quantities of production levels projected for the upcoming season (7800, 12000, 14000). According to the previous demand estimates, the total quantity demanded is 12000. Therefore, the production level of 7800 jackets does not match the demand estimated; there is a demand shortage of 4200 jackets, which will result in disadvantage, explained as follows. When compared this quantity level of production with the 12000 production level, there is an $84,000 profit difference between both levels, which makes us determine that between both the most appealing alternative for profit maximization is the 12000 production level. On the other hand, the 14000 production level generated a total profit estimate of $40,000; his amount can be translated into a loss of $100,000 when compared to the 12000 production level. Meaning that, 2000 extra jackets produced over the estimated demand will be sold at $30 per unit instead of $100. However, if these 2000 extra jackets were to be sold at full price ($100 per unit) profits would increase by $40,000. Finally, when comparing all three production levels, we can conclude that the most suitable alternative, that comprises t he most benefits, in terms of profit maximization, is the 12000 quantity production level.
