Structural Performance Of Lightweight Concrete

Structural Performance Of Lightweight Concrete The Romans reportedly first used lightweight concrete during the eighteenth centuries. The application on the The Pantheon where it uses pumice aggregate in the construction of cast in-situ concrete, according to Hjh Kamsiah Mohd Ismail, Mohamad Shazli Fathi and Norpadzlihatun bte Manaf (2003), all with the Universiti Teknologi Malaysia Institutional Repository, confirms the Romans use of lightweight concrete. In the journal article, Study of lightweight concrete behavior, Ismail, Fathi and Manaf recount that during the late nineteenth century, American and English builders used clinker, a form of lightweight concrete in their construction projects like the British Museum as well as in low cost housing. DAnnunzio (2003) reports: Lightweight concrete can achieve similar strengths as standard concrete, and it produces a more efficient strength-to-weight ratio in structural elements (p. 2). During the research paper which investigates the structural performance of lightweight concrete, the author asserts: When the builder or developer uses lightweight concrete, then à ¢Ã¢â€š ¬Ã‚ ¦ completing hypothesisà ¢Ã¢â€š ¬Ã‚ ¦ the rest is just to show progressà ¢Ã¢â€š ¬Ã‚ ¦. DAnnunzio (2003), reports the use of lightweight concrete as a roof decking and insulation system has expanded in the past five years. Increased usage can be attributed to the recent industry-wide insulation shortages and delamination deficiencies (p. 1). The increase can also be attributed to the economic and environmental advantages that lightweight insulating concrete (LWIC) provides in roof assemblies. Lightweight insulating concrete (LWIC) provides The reported recent industry-wide insulation shortages and delamination deficiencies. The increase can also be attributed to the economic and environmental advantages that in roof assemblies. lightweight concrete as a roof decking and insulation system has expanded in the past five years. Increased usage can be attributed to The lightweight concrete was also used in construction during the First World War. The United States used mainly for shipbuilding and concrete blocks. The foamed blast furnace-slag and pumice aggregate for block making were introduced in England and Sweden around 1930s. Nowadays with the advancement of technology, lightweight concrete expands its uses. For example, in the form of perlite with its outstanding insulating characteristics. It is widely used as loose-fill insulation in masonry construction where it enhances fire ratings, reduces noise transmission, does not rot and termite resistant. It is also used for vessels, roof decks and other applications. Figure 5 shows some examples of lightweight concrete used in different forms. Lightweight insulating concrete (LWIC) provides The reported recent industry-wide insulation shortages and delamination deficiencies. The increase can also be attributed to the economic and environmental advantages that in roof assemblies. lightweight concrete as a roof decking and insulation system has expanded in the past five years. Increased usage can be attributed to Lightweight concrete can achieve similar strengths as standard concrete, and it produces a more efficient strength-to-weight ratio in structural elements DAnnunzio (2007, p. 2). John A. DAnnunzio (2003), president of IRT Inc., asserts in the article, New Lightweight Concrete Technology, as with all site installed materials, the quality of the finished product is based on the skill level of the applicator. Structural lightweight concrete, made with accumulation of lightweitght concrete aggregate, has been used in the United States for approximately 50 years. The article, Concrete in practice, what, why and how?, (2003) explains structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115lb/ft3 (1440 to 1840 kg/m3) compared to normal weight concrete with a density in the range of 140 lb to 150lb/ft3 (2240 to 2400kg/m3) (p. 1). Lightweight aggregates, such as clay, shale or slate materials, are typically used to make structural lightweight concrete. These lightweight aggregates are fired in a rotary kiln to cause this type concrete to have a porous structure. Air-cooled blast furnace slag may also be used to create lightweight concrete aggregates. There are other classes of non-structural lightweight concretes with lower density made with other aggregate materials and higher air voids in the cement paste matrix, such as in cellular concrete (Concrete in practiceà ¢Ã¢â€š ¬Ã‚ ¦, 2003, p. 1). This type of concrete is typically used for insulation properties only. Lightweight concrete may be produced by injecting air in to the composition, by leaving out the finer sizes of the aggregate or by replacing the aggregate with hollow or porous aggregate. Hjh Kamsiah Mohd Ismail, Mohamad Shazli Fathi and Norpadzlihatun bte Manaf (2003), all with the Universiti Teknologi Malaysia Institutional Repository, purport in the journal article, Study of lightweight concrete behavior, particularly, lightweight concrete can be categorized into three groups: No-fines concrete Lightweight aggregate concrete Aerated/Foamed concrete (p. 5). No-fines concrete may be defined as lightweigh concrete that is created by combining cement and fine aggregate. This type of concrete has evenly spaced holes throughout it. Strucural lightweight concrete is mainly used to minimize the dead load of a structure that is made out of concrete. This allows the designer to decrease the size of columns and footings, or other load bearing essential features. Structural lightweight concrete mixtures can be designed to achieve similar strengths as normal weight concrete. The same is true for other mechanical and durability performance requirements (Concrete in practiceà ¢Ã¢â€š ¬Ã‚ ¦, 2003, p. 1). Strucutral lightweight concrete also produces a better strength to weight ratio for structural materials. Although lightweight concrete is more expensive than traditional concrete, the cost is offset because of the reduced volume of lightweight concrete, allowing designers to use less, which turns out to be less cost. When builders and developers choose to use structural lightweight concrete, the construction costs are lower and the building is much more durable. The researcher will purport the: Advantages and disadvantages of lightweight concrete; High Performance Fiber Reinforced Lightweight Concrete Proper Mixing Methods Volcanic Pumice Offer Conclusions Advantages of Lightweight Concrete Two of the distincitive features of lightweight concrete are its low density and thermal conductivity. Ismail, Fathi and Manaf (2003), explain advantages are that there is a reduction of dead load, faster building rates in construction and lower haulage and handling costs. Lightweight concrete maintains its large voids and not forming laitance layers or cement films when placed on the wall (p. 1). A great example of the durability of lightweight concrete is The Pantheon in Rome, which was built over 18 centuries ago. Sructural lightweight concrete is in high demand for use in construction because of its lower density which results in designers ability to have a smaller foundation due to the use of smaller load bearing elements or cross sections. Harun Tanyildizi and Ahmet Coskun (2008), both with the Department of construction education, Firat University Elazig, Turkey, explain in the journal article, The effect of high temperature on compressive strength and splitting tensile strength of structural lightweight concrete containing fly ash, lightweight aggregates are broadly classified in to two types-natural (pumice, diatomite, volcanic cinders, etc.) and artificial (perlite, expanded shale, clay, slate, sintered PFA, etc.). Lightweight concrete can easily be produced by utilizing natural lightweight aggregate i.e., pumice or perlite aggregate ( ¶ 2). The main advantages to using structural lightweight concrete are increased strength, more flexible and less coefficient of thermal expansion. Disadvantages of Lightweight Concrete Lightweight concrete applications do have certain disadvantages and liabilities, typically having to do with the cabability of the contractor istalling it. John A. DAnnunzio (2003), president of IRT Inc., asserts in the article, New Lightweight Concrete Technology, as with all site installed materials, the quality of the finished product is based on the skill level of the applicator. Lightweight concrete has additional constraints because the success of the system is based on the proper mix ratio (p. 2). One of the major problems with lightweight concrete is if the lightweight concrete is not mixed properly, it may have empty spaces that can lead to deficient strength. The compressive strength of lightweight concrete come from a foam additive, when it is mixed correctly, this additive molds around the cement which serves as an aggregtae. If the foam additive is not properly mixed, there is a probability of foam collapse, which weakens the products compressive strength (DAnnunzio, 2003, p. 2). One of the factors that leads to lightweight concrete failing is the mixing process is typically done at a jobsite, which may lead to human errors. Concrecel USA has developed pumping equipment that percisley weighs the ingredients and accurately mixes the foam and cement, to elimante the problem of human error. Table 1 depicts the advantages and disadvantages of lightweight concrete. Table 1: Lightweight Concrete Advantages/Disadvantages(Ismail, Fathi Manaf, 2003, p. 8). Advantages of Lightweight Concrete Disadvantages of Lightweight Concrete Quick and relatively simple construction Very sensitive with water content in the mixtures Economical in terms of transportation as well as reduction in manpower Difficult to place and finish because of the porosity and angularity of the aggregate. In some mixes the cement mortar may separate the aggregate and float towards the surface. Significant reduction of overall weight in saving structural frames, footing or piles High Performance Fiber Reinforced Lightweight Concrete Typical lightweight concrete is weaker than traditional weight concrete. It is critical to improve the strength of lightweight concrete in order to promote it for use for structural applications. Bengi Arisoy, Department of Civil Engineering, Faculty of Engineering, Ege University, Bornova, Turkey and Hwai-Chung Wu (2008), Advanced Infrastructure Materials Laboratory, Department of Civil and Environmental Engineering, Wayne State University, Milwakee, explain in the journal article, Material characteristics of high performance lightweight concrete reinforced with PVA, with a much higher ductility high performance fiber reinforced lightweight concrete (HPFRLWC) becomes superior to regular concrete because of elimination of sudden catastrophic failure of otherwise brittle concrete. Ductility results from imposed crack resistance due to bridging fibers (Theoretical background section,  ¶ 1). The researchers found that fiber reinforced lightweight concrete, when made with lightweigh ag gregates and air entraining agent, displays strain hardening by the addition of 1.5% fiber volume fraction. By adding about 10-20% fine cement substitute such as fly ash and silica fume, it improves both ductility and flexural strength. Improvement of high performance FRLWC may be summarized as follows: 50-150 times (5000-15000%) increase in flexural displacement (ductility) at ultimate load than plain lightweight concrete, 50-250% increase in ultimate flexural strength than plain lightweight concrete, 30-65% decrease in weight than normal weight concrete (Arisoy Wu, 2003, Conclusion section,  ¶ 1). Proper Mixing Methods The concrete mixture design, especially for lightweight concrete, has stressed compressive strength, and also the durability of the concrete. Chao-Lung Hwang Department of Construction Engineering, National Taiwan University of Science and Technology, Taiwan and Meng-Feng Hung (2005), Department of Civil Engineering, National Taiwan University of Science and Technology, Taiwan assert in the journal article, Durability design and performance of self-consolidating lightweight concrete, ACI 318 structure code stresses both the maximum w/cm ratio to highlight the usage of pozzolanic material, and the minimum 28-day compressive strength to guarantee construction safety while considering durability of normal weight concrete ( ¶ 2). If a concrete structure cracks or become porous, it is more sustable to be subjective to harsh outside elements, such as acid rain and seawater, that may lead to its deterioration and the quality of a structure. Lightweight aggregate has a porous feature, because of that its compressive strength is typically low and the capacity it has for absorpution is fairly high. Hence, it needs large amount of cement paste to achieve suitable workability and designed compressive strength. This may violate the durability requirement of normal weight concrete as mentioned ( ¶ 4). Because the porous aggregate reduces the density of the lightweight aggregate concrete (LWC) and because it fractures easily when mixed, it is critical to design the LWC with increased strength and durability. In various field conditions, lightweigh concretes, in regards to carbonation performance, have typically performed adequately. T.Y. Lo, W.C. Tang and A. Nadeem (2008), all with the Department of Building and Construction, City University of Hong Kong, Kowloon, Hong Kong, explain in the journal article, Comparison of carbonation of lightweight concrete with normal weight concrete at similar strength levels, some field investigations on the carbonation performance of LWC in ships and bridges at exposure age from 15 to 43 years, compressive strength from 23 to 35 MPa and density from 1650 to 1820 kg/m3 have been reported (Carbonation of lightweightà ¢Ã¢â€š ¬Ã‚ ¦section,  ¶ 1). The depth of carbonation in these structures varied in regards to exposure conditions, density and strength, and was typically less than 10 mm. What effect moisture content, porosity and cement to water ratio have on the limits of carbonation, have been studied by researchers. For example, Swenson and Sereda, prominent researchers found that the moisture content in lightweight concrete, whether high or low, was not favorable to rapid carbonation. Swamy and Jiang found that carbonation was higher for concrete with higher total porosity at a given water to cement ratio. Bilodeau et al. attributed the low carbonation in high strength LWC to low water to cement ratio (Lo, Tang Nadeem, 2008, Carbonation of lightweightà ¢Ã¢â€š ¬Ã‚ ¦section,  ¶ 2). Finally, Gunduz and Ugur analysed the carbonation of pumice aggregate lightweight concrete and expressed the carbonation was lessened when the aggregate to cement ratio of lowered. Volcanic Pumice This one is way over my head need to add a little from 8-next page 80 in raw research Pumice, a natural material, comes from volcanos when gases are released and the lava solidifies. Khandaker M. A. Hossain, Associate Professor in the Department of Civil Engineering at Ryerson University, Toronto, Canada and Mohamed Lachemi (2007), a Canada Research Chair in Sustainable Construction and a Professor in the Department of Civil Engineering at Ryerson University, both ACI members, assert in the journal publication, Mixture Design, Strength, Durability, and Fire Resistance of Lightweight Pumice Concrete, world pumice production was 14.4 million metric tones Mt in 2004. Globally, Italy remains the dominant producer of pumice, with production estimated to be 4.6 Mt per year ( ¶ 3). Pumice is mainly used an an aggregate in lightweight building block and other building products. Volcanic pumice (VP) has been utlizied as an aggregate in producing lightweight concrete. Pumice has been used for builing over 2000 years, especially in Rome and Europe where many pumice structures are still standing to this day. Lightweight concrete made with pumice and pozzolanic cement with volcanic ash/lime (developed in Mexico by the Totonacas) has survived more than 2000 years and provides an example of a low strength concrete and very long-term performance (Hossain Lachemi, 2007,  ¶ 4). Using pumice and perlite as additives has been found to supply increased resistance to the freezing and thawing of concrete, cement pastes and mortar.

Philosophy of Education: Herbert Marcuse

Philosophy of Education: Herbert Marcuse Joseph Cunningham Praxis Exiled: Herbert Marcuse and the One Dimensional University,  Journal of Philosophy of Education Vol 47 No 4 2013 Cunninghams exploration of Herbert Marcuse positions him at the centre of the revolutionary student movements of the 1960s. Higher education could at that time be seen as a place which was shielded to some extent from the pacifying tendencies within advanced capitalist labour. Of all the theories which emerged out of the influential Frankfurt School, Marcuses was perhaps the one theory which could more easily beapplied in practice because it narrowed Marxist critique to analyse the extent to which advanced capitalisms influence penetrated inwardly. Cunningham encapsulates this by stating, gendered rhetoric aside, One Dimensional Man, is about you and your life. However, Cunningham argues that it was never Marcuses intention to develop his theory, whilst navel gazing inside an ivory tower. Rather critical theory in education should move students to pierce through the institutional walls and function as actualised praxis, the congruence of theory and action. Cunningham uses Marcuses own words from 1968, By its own inner dynamic, education thus leads beyond the classroom, beyond the university, into the political dimension and in to the moral, instinctual dimension (his italics). An inner revolution is a precursor to outer revolution and dialectical critique is the key to the liberation which will nurture that inner revolution. Marcuse looked beyond labour itself to find the causes of what he thought was creating a one dimensional society: he argued that technology, the media and a converging standardisation of values coupled with an unending stream of must have commodities combine to attack an individuals authenticity. Reason is usurped by technological rationality and our critical senses are dulled, making us, as Marcuse argued, disinterested in or even hostile to dissent. Cunningham carefully traces how the ripe revolutionary potential of the 1960s has come under the control of capital, as Marcuse predicted might be the case. I can see how the growing corporatisation of higher education, of which Marcuse was aware in 1960, has indeed spread tentacles across the sector. The perceived waste of human capital in the liberal arts has been either recycled into more useful courses or disposed of. Cunninghams view is that, as Marcuse predicted, the drive to develop online education can arguably be seen as another route to seal the packaging of educational content as a product for students as consumers, so much so that the consumer and campus culture are indistinguishable. The halcyon days of free education have been replaced by a narrowing of access due to lack of means. Cunninghams conclusion is bleak but understandable: even though critical theory is still taught, it is largely devoid of praxis and often delivered online in digitally standardised curricula. Marcuse would find it empty of the dynamic which he felt it had the potential to bring to student life. Like Marcuse, however, Cunningham sees some evidence of counterculture: citing the Occupy Movement as one candle in the darkness of the pervasive atmosphere which is antithetical to critical thought. Self-exile beckons for those who, like Marcuse before them, seek to step outside to look within with fresh eyes. There are indicators everywhere we look of the dominant capitalist culture which makes us so wrapped up in our daily existence and desire for material goods that we fail to see the possibility of any other existence. Indeed, we are led to crave the same dimension. Marcuses One Dimension flattens our capacity for imagining another kind of existence and suppresses our instinctive desires. Whether it is the subliminal appeal of an advertising jingle or the promise of a higher salary if we put all our energies into STEM, we are persuaded that our present should be used to build our future. However the vision is as narrow as a tunnel. The light at the end is that of unexamined material prosperity: there are few unexpected rays lighting the corners of our imagination to help us to reach out to change our perspective. After all, evidence of a different light source might encourage us to look for another way out. Word count: 663 References Brookfield, S. (2005).

Kanes Blasted Essay -- Theater Play Analysis

â€Å"I’ve only ever written to escape from hell-and it’s never worked-but at the other end of it when you sit there and watch something and think that’s the most perfect expression of the hell that I felt then maybe it was worth it. (Sarah Kane, Royal Holloway College, London, 3 November 1998).† (Saunders. 2002: 1). Both representative and reflected in this statement made by the British playwright Sarah Kane (1971-1999) (Sierz. 2001: 90-91) is the state of being human. In its literal sense the state of being human could be illustrated as an expression of existence. That of the individual and characteristics and traits experienced through the life of mortal man. (Oxford English Dictionary. 2006: 61 & 366). In addition to this, the associated meaning with the word ‘tested’ suggests ‘a difficult situation that reveals the strength or quality of someone or something.’ (Oxford English Dictionary. 2006: 785). When defined in t hese terms, this then opens up the question to how an expression of human-existence is revealed under pressure in Sarah Kane’s play Blasted (1995). The twentieth century British playwright Sarah Kane’s (1971-1999) first and sensational drama Blasted opened in the Royal Court Theatre Upstairs, London, in January 1995. (Saunders. 2002: 2). From the outset Kane’s play stirred much controversy within the media.

Indigenous Health Case Study Essay example -- Healthcare Culture

Introduction Health is known as a state where an individual is socially, mentally and emotionally stable without the presence of any illness, disease or infirmity (Carson, 2007). Jenny, an indigenous woman is 34 weeks pregnant, she has been complaining about her abdominal pains and after seeing the flying doctor, she was asked to fly back with him as she might be in an early labour. Jenny is concerned about her family; she wonders how they will manage without her. Her mother-in-law lives with her sister-in-law and she wonders if she will be able to come and help as her mother has a diabetic leg ulcer and needs treatment so cannot travel. This essay will discuss about the health issues before colonization and after colonization, Jenny’s situation and how she faces the culture clash and dispossession, it will also look at the models of health and theories and how that affects Jenny’s life. Culture clash and indigenous dispossession at the time of colonization. Culture clash is how people behave, whether or not people recognise each other as human beings and if they share what they believe, have similar values and beliefs (Eckermann, Dowd, Chong, Nixon, Gray, & Johnson, 2006). The process of colonization is when a nation imposes itself economically, politically and socially upon another nation (Germov, 2009). People belong to different cultures; every culture has its own customs and beliefs that everyone has to follow. Culture clash can occur when people look at different cultures as not to be a part of their culture and different people as not their people (Eckermann et al., 2006).

Arrow of Time: Towards a New Epistemology of Science :: Scientific Philosophy Philosophical Papers

Arrow of Time: Towards a New Epistemology of Science ABSTRACT: Humanity has tried to comprehend two fundamental events since time immemorial: the birth of the universe and the emergence of life. Recently, it is claimed that these events can be understood comprehensively by means of a metaphor: the 'arrow of time.' The purpose of the present paper is twofold: (1) to build an epistemological structure that underlies the principle of time's arrow; and (2) to pursue the unity of science in a novel fashion. (A) WHAT IS AN ARROW OF TIME? The events which we see in the universe are classified into two categories: the reversible and the irreversible. The arrow of time is relevant to the latter than the former. It is alongwith the reversible-irreversible syndrome that a major light can be thrown on the notion of time's arrow. Concept of Reversibility The reversible events are those which occur regularly and repeatedly, the cycles of seasons, harvesting , pendulum swinging in a frictionless medium , the motion of earth and the moon , are some of the examples. Reversibility is an idealized concept . A process is said to be reversible if and only if the system which undergoes that process together with all parts of its environment which are affected, can be restored reproducibly to their original states. In short, in the reversible process all relevant parts of the universe must be capable of being put back to how they were! Time is not so considered to be an important ingredient in this system. The entire Newtonian Science is of this sort. Newton's laws , Maxwell's equations, Einstein's general relativity and even quantum mechanics- all remain effectively unaltered if we reverse the direction of time ( Replace the ' t ' which represents time by '-t' ). Even in life and the social sciences, time is not considered to be important com ponent in these system of knowledge. The notion of time's arrow is very important in the context of irreversible processes. Irreversibility defined Irreversibility is the negation of reversibility. It is a realistic notion. Moreover, it is the one-way time evolution of the system, giving rise to the non-repetitive , non-cyclic processes or events. The examples are , mixing a milk in the coffee, transfer of heat from a hotter body to a cooler one, chemical changes, the state of turbulence and chaos, rhythms, non-equilibrium systems, metabolism etc. Irreversibility is an open system in the sense that it interacts with its surrounding area and evolves simultaneously.

The Flynn Effecct

Coupled with the given assumption, I do agree that human being is getting smarter. The reason of the growth in humans intelligent is affected by several factor. The factor that took Into consideration is shown as below: – 1. 1. 1 Technology: The conveniences that technology brought to this society, not only bringing conveniences to our daily. It also shift the human Intelligent paradigm to towards the right. Therefore the Intelligence Quotient (IQ) score are rising at the rate of 3 IQ points Increased per decade. 1. 1.Right to education: In the olden days, education could only affordable for the royalty and the rich. However, civil revolution has brought the awareness of the Importance of education. After World War II (1945), education system has embark the education system across some national(s). At the global level, Article 13 of the United Nations (1966), under the department of International Covenant on Economic, Social and Cultural Rights recognizes the right of everyone to an education. This recognition has strengthen the right for everyone to learn, having the opportunity for education, human intelligent end to continually increase as well. . 1. 3 Individual Psychology Behavior towards Media Influence (Media Psychology): Media psychology studies how media as a factor influence how people perceive, interpret, respond and interact in this cutting-edge century. To be able to perform as a media user, language abilities and reading is important. The increase of this awareness, indirectly influence human eager to learn and speak for their voice. Having this unaware awareness, it also helped in the human intelligent paradigm shift. This factor may not appear as an obvious factor UT it is a grey area to be studied further. 1. Which of the factors explaining the Flynn effect do you accept? Drawing upon the understanding towards the given case, the Education factor and Test-taking as'. N. Y factor are the main drives towards the growth in human intelligent . 1. 2. 1 Education: Students today are better educated than their ancestors, and education leads to higher test scores. 1. 2. 2 Test-taking save,y: Today's children have been tested so often that they are test-savvy. They know how to take tests and how to do well on them. 1. 3 If the Flynn effect is true, does this undermine the theory that IQ is most inherited?Why or why not? Based on the background study and understanding towards IQ, human intelligence Is not only difficult to measure; it is also difficult to define. Intelligence Is a combination of what we know (Knowledge), skills and ability to understand and reason – that Is the cognitive abilities continue to grow throughout our lives, rather than being set at birth. To answer this question In precise, IQ has only small percentage Is Inherited, biology Is only part of the Intelligence package; other factors Including our dally bobtail, what we eat to where we live, can also affect our Intelligence.

Moral Courage Essay

Moral courage is a concept means doing the right thing, it means listening to conscience that what does it saying. Standing on what believe. Moral courage has three major elements witch are principle, endurance and danger. it means moral courage and doing right things make us in the risk, we may face fear and danger for example with losing o job and security, reputation or etc. But falling in the risk is not matter because we follow our conscience and it is important because I believe that conscience is based on values and show us the way to be human. Moral courage is standing up for values such as honesty, fairness, compassion, respect and responsibility but just having these values are not enough we have to try to put them into practice and we have to commitment to moral principles as well, so in the practice we may face with danger and we have to confidence to endure hardship, suffer and sacrifice. In this sense we can see moral courage in action. According to Kennedy (1956) moral courage is â€Å"the Basis of All Human Morality.† he mentioned that Courageous men do as they do because they love themselves, they respect themselves and their reputation for integrity and their personal standard of their ethics all are more important than their popularity with others or desire to maintain their offices. For having these all values they have to fall in the risk as it done with senator George Norris, with Nelson Mandela and Malala Youssafzai, that all of them stood on what they believed and what they knew that is right. They struggled for higher purpose and having greater values such as human rights and for justice and they found these straggle as their duty to fulfill their obligation. So as consequence we saw that all of them faced with challenges and danger and they endured hardship situation but they could to have significant acheivement. for World War 1 that was started in 1914, US government declared that they would remain neutral but in reality it was not like this and US supported England by carrying guns through Armed Merchant ships and was against German so after German submarines sank three American Merchant Ships in 1917, president Wilson declared for entering into WW1 and asked for congressional approval. Senator Norris was opposing of US entre into World Ward 1 so he filibustered the Armed merchant Ship bill and he faced with very hardship situation and condemned by American press but he didn’t gave up and he believed on the rightness of his course, he was not care about holding his office he just listened to his conscience and tried to say truth to people. So finally he did and informed people about the reality that is behind of this policy he said that these ships used for carrying war supplier to England and country try to enter in the war because of financial benefits of a certain groups of people. Senator Norris did a moral courage action because he said the truth to the people he knew about the terrible result of involving in the WW1 and he believed that war brings no prosperity to great mass of people so his consciences made him to make judgment although his political career was under risk but he pursued justice. Regarding Nelson Mandela, I have to say that he struggled against apartheid and racial discrimination and inequality. Many movements and protests were raised with his leadership against Apartheid and he also joint to Afghan National Congress and tried to provide equality for the black people and give them their rights but he understood that these kind of nonviolent protests or movements do not work in the society that is commanded by group of people who doesn’t follow their conscience so he decided to involve in sabotage and planned for armed struggle. When he arrested by state, he and his fellows didn’t deny his involvement in sabotage and armed struggle he said the truth and he indicted state for discrimination, for inequality, for abuse of black people’s right and freedom. He said that state should feel guilty. Mandela wanted a light future for black people and the basic rights which were neglected by state. He wanted a society that all people can live together in a peace and harmony. In the court he spoke up with integrity and truth as a result he could bring prosperity for black people. He suffered and endured 27 years of his life in prison for his vision and when he was elected as a president, he focused on fostering racial reconciliation and forgiving his oppressors in Apartheid regime. Above all show his moral courage struggle and even after he came to power as president. Malala Youssafzai also was another example who stood on women right for education as it was banded by Talban regime.
