Research Design & Methods Literature Review

Question: Discuss about theResearch Design Methodsfor Literature Review. Answer: Introduction The present research is undertaken to evaluate and examine the use of nano materials in concrete. Nano materials can be described as the smallest particle of nano-scale dimensions produced by nanotechnology. The materials are used in preparation of concrete with the increasing development in nano-science. In this context, the present research addresses the significance of nonmaterial for construction industry with special reference to concrete. The literature review addresses the past, present and future developments with reference to use of nano-materials in concrete industry. Discussion of Literature Use of Nano-Materials in Concrete Industry As per the views of Chakraborty and Kim (2014) the construction industry is emphasizing on the use of nano-materials for concrete making. Nano-particles can be defined as engineered particles comprising of size 1-100nm developed with the use of nanotechnology. The construction industry of any country contributes heavily to the growth of its GDP (Gross Domestic Product) through providing employment and also energy resources. The construction industry is incorporating the use of nanotechnology materials largely for extending the lifetime of the constructional structures. According to Joharia, Ahmadb and Maslehuddinc (2014) the nano-materials also prevent the occurrence of various hazards such as fire, corrosion, fractures and cracks by incorporating in the concrete. The use of concrete in development of cement results in its better generation by making it more durable and strong. The most important nano-materials being used in the formation of concrete are nano alumina, nano-titania and nano-silica. Nano-Alumina is increasing the mechanical properties of cement through increasing its strength and activating its hydraulic properties. Also, nano-alumina makes cement to settle faster and decreases its temperature by acting like flux. In the opinion of Chuah et al (2014) nano-titania particles are used in development of concrete as it is known to have properties of increasing the stability, anti-corrosiveness and photo-catalytic characteristics of the cement. Also, nano-titania is believed to possess self-cleaning properties and thus makes concrete pollution cleansing and self disinfecting. The use of nano-titania also extends the design life of concrete by disintegrating the organic pollutants into harmless carbon dioxide and water in the presence of sunlight. Thus, buildings encompassing the use of nano-titania stay clean and beautiful for longer duration of time. Spiesz and Brouwers (2014) have stated that Nano-silica is also being largely used in concrete development due to its large tensile strength and large surface area. Also, it is known to have properties of preventing silicosis and reduces the occurrence of pollution when it is being mixed in concrete. The particles of silica also reduce the alkaline properties of concrete and enhance its resistance against the attack of chemical agents. Thus, it can be said that the use of nano-materials plays an important role in decreasing the environment pollution and also increases the durability of concrete. Therefore, it can be said that incorporation of nano-materials is extremely useful for sustainable development of concrete industry. Past, Present and Future use of Nano-Materials in Concrete According to Patil and Pendharkar (2016) nano-materials have extensive potential to be used in the development of construction industry materials. They are providing various advantages to the construction industry through increasing the strength and workability of concrete. The resistance power of concrete gets increased through the incorporation of nano-materials and thus infrastructure developed stays durable and beautiful for longer period of time. The evolution of nano-sconce in the past has caused the development of nano-materials and their use in construction industry. The achievement of better outcomes through their utilization has resulted in their greater use in present days in concrete. They have been used in past to develop germ-free laboratories, hospitals, waterproof buildings and for environment protection. The nano-materials are also used largely in present for preventing the occurrence of environment pollution and increasing the design life of concrete. Yu et al. (2014) have stated that the realization of numerous advantages of nano-materials has caused the RD researchers to examine and analyze their use in concrete in future context. The research and development scientists are actively involved in analyzing the various properties of nano-materials for examining their future potential in concrete development. The scientists have argued that though nano-materials have various potential benefits to be used in construction industry there are also some serious limitations for their use in concrete. The major drawback associated with the use of nano-materials is the occurrence of various health issues with their use as they are smallest particles that can easily enter the respiratory systems of human beings. Also, the high cost involved in the use of nano-materials in concrete making may restrict its extensive use in construction industry. The nano-products are very expensive to be used due to use of high technology devices for producing them. Thus, manufacturers are not adopting the use of nano-materials in development of concrete. The lack of awareness among the manufacturers is also a major factor involved in restricting the use of nano-products in concrete. Research Methodology used in Literature Review The literature review has incorporated the use of qualitative research method to explore and examine the various facts related to use of nano-materials in concrete with reference to past, present and future. The qualitative research method involves collecting information from various academic sources related to the research topic and extracting the key facts from them. Summary of Key Issues and Findings Thus, it can be summarized form the overall literature review carried out nano-materials use in construction industry is very beneficial for supporting its growth and development. Nano-materials increases the design life of concrete thus enhancing the sustainability of infrastructure developed. The use of nanotechnology has caused the development f various new building projects. Thus, nano-science cause large scale changes in the construction industry by providing it various economic benefits. The implications for the future researchers as analyzed from reviewing the literary source related t the topic exist finding the mechanisms by which nano-materials impacts the flow properties of concrete. There is high need to investigate the properties of concrete comprising of varying percentages of nano-materials as partial replacement of cement. References Chuah, S., Pan, Z., Sanjayan, J.

Premarital Counseling and Its Effects on the Longevity of a Marraige E

In the United States of America, less than 50 percent of marriages are considered to be successful marriages; which means that more than half of them fail. (Phillips, Willmoth, we have a seriously growing problem. The dwindling of our marriages result in a deteriorating of our families, and if the families flop our society fails. What can we do to protect our society from utter ruin? Believe it or not, it all starts with saving our marriages. It is the belief of trusted psychologists, therapists, and members of the clergy that premarital counseling could be the resolve to this growing epidemic. We hear this all the time, but does it really work? Is it sincerely worth going through? The research set forth in this work will give a brief examination of the following: what a Marriage is, the definition of pre-marital Counseling and its Purpose. It will also observe the methods and styles of Pre-Marital Counseling. Finally, we will actually gaze into some of the effects it may have on a marriage. So then, what is a marriage? This question is often asked by many who are peripatetic around the idea of getting married. (Smith, 2008) In truth, a marriage is a collaborating relationship between individuals who have agreed to come together with governmental, social, or religious recognition, based on a fervent bond. (Cunningham, 1999) We have come to identify and understand marriage as a legally recognized union of a male and a female party either by ceremony or common law. (Smith, 2008) Due to the changes of the course of time, marriage now entails dissimilar meanings. (Cunningham, 1999) Marriage is now identified, in some people?s minds, as a loving relationship between two people in which they overtly promise to remain together ?for better or worse, for richer or poorer, in sickness and in health until death?. (Cunningham, 1999) However, little emphasis is placed on the commitment of marriage. (Cunningham, 1999) The focus of young couples aspiring to be married is love and emotional disposition. (Cunningham, 1999) Marianne Moore describes a marriage as an enterprise used as a tool by which the self-deceived naively hope in the effectiveness of what she called, ?public promises? to fulfill a ?private obligation? (Holley, 1987) Moore goes further to say,? psychology which explains everything explains nothing,? which implies that many simply have a lack of understanding of what marriage really is. It sounds logical, but yet it does not make sense. (Holley, 1987) If that were not interesting enough, she takes it to another level by making mention of the first marriage between Adam and Eve. Their marriage is placed into a very rigid perspective with which she describes their marriage as uncomfortable and a troubling inconvenience. (Holley, 1987) The poem ?Marriage? is often viewed as an attack on marriage, due to Marianne?s use of metaphoric language to explain in detail the very serious, and sometimes harsh, realities of marriage. (Holley, 1987) However, marriage is no fairytale, and it is very little happy endings in life. She speaks very bluntly about two people who are self-absorbed and self-centered. (Holley, 1987) Their main concern is their own needs, likes, dislikes, and opinions. (Holley, 1987) On the contraire, marriage is an agreement to be utterly concerned with the other person. Just look at the vows taken by both parties; ?I, (your name), take you (spouse?s name), to be my (wife/husband), to have and behold from this day on, for better or for worse, for richer, for poorer, in sickness and in health, to love and to cherish; until death do us part.? (Unknown, 2013) These vows do not express any form of selfishness. They present the idea that my new passion in life is to behold, love, and cherish this wonderful human being I have taken as my spouse. (unknown, 2013) As wonderful as this might sound, this is not as wonderful to do. This level of commitment can be seriously painful to do at times. Just think, it is greatly challenging to make someone else the sole concern of one?s

Happy Feet Movie Quotes

'Happy Feet' Movie Quotes Live your life to the fullest. Dont be afraid to be yourself, no matter who you are. These are the heart-warming lessons you learn through the song-and-dance animated movie Happy Feet. The movie takes place in Antarctica in the home of the emperor penguins. Each penguin sings a heartsong to attract a mate, but young Mumble is a terrible singer. Mumble can tap dance though, and he eventually wins over his heartthrob with his clever footwork. George Miller, the writer-director of Happy Feet, used sophisticated computer animation to create this visual treat. The voice-overs by Nicole Kidman, Hugh Jackman, Robin Williams and Elijah Wood are part of why Happy Feet won the 2006 Academy Award for Best Animated Feature. For Penguin lovers, here is a collection of memorable Happy Feet quotes. Ramon Just a moment... I hear people wanting something... ME! We got  personality  with a capital Y. Why? Because were hot! I like big tails and I cant deny! Oh, hes leaving! Oh, no! That was his face! I dont care where you come from, that has got to hurt! STOP! Lemme tell something to  joo...

Dependent Variable Definition and Examples

Dependent Variable Definition and Examples A dependent variable is the variable being tested in a scientific experiment. The dependent variable is dependent on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded. When you take data in an experiment, the dependent variable is the one being measured. Common Misspellings: dependant variable Dependent Variable Examples A scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off. The independent variable is the amount of light and the moths reaction is the dependent variable.  A change in the independent variable (amount of light) directly causes a change in the dependent variable (moth behavior).You are interested in learning which kind of chicken produces the largest eggs. The size of the eggs depends on the breed of chicken, so breed is the independent variable and egg size is the dependent variable.You want to know whether or not stress affects heart rate. Your independent variable is the stress, while the dependent variable would be the heart rate. To perform an experiment, you would provide stress and measure the subjects heartbeat. Note in a good experiment, youd want to choose a stress you could control and quantify. Your choice could lead you to perform additional experiments since it might turn out the change in heart rate after exposure to a decrease in temperature 40 degrees (physical stress) might be different from the heart rate after failing a test (psychological stress). Even though your independent variable might be a number that you measure, its one you control, so its not dependent. Distinguishing Between Dependent and Independent Variables Sometimes its easy to tell the two types of variables apart, but if you get confused, here are tips to help keep them straight: If you change one variable, which is affected? If youre studying the rate of growth of plants using different fertilizers, can you identify the variables? Start by thinking about what you are controlling and what you will be measuring. The type of fertilizer is the independent variable. The rate of growth is the dependent variable. So, to perform an experiment, you would fertilize plants with one fertilizer and measure the change in height of the plant over time, then switch fertilizers and measure the height of plants over the same span of time. You might be tempted to identify time or height as your variable, not the rate of growth (distance per time). It may help to look at your hypothesis or purpose to remember your goal.Write out your variables as a sentence stating cause and effect. The (independent variable) causes a change in the (dependent variable). Usually, the sentence wont make sense if you get them wrong. For example:(Taking vitamins) affects the numbers of (birth defec ts). makes sense(Birth defects) affects the number of (vitamins). probably not so much Graphing the Dependent Variable When you graph data, the independent variable is on the x-axis, while the dependent variable is on the y-axis. You can use the DRY MIX acronym to remember this: D - dependent variableR - responds to changeY - Y-axis M - manipulated variable (one you change)I - independent variableX - X-axis

Answer question - Essay Example y, orders used to circulate from the customers to the hands of brokers to went to the floor desk to the order desk to the executing broker to the runner and then back again, and therefore errors used to be common(Sykes, 1983). In reality, this errors cannot have an impact on the capital today. The moment an error is discovered, and as well the market is still open, it is just the role of the order desk to get out the error and finally, need to determine the fault. However, determining fault is usually easy. Perhaps, double-checks in the system should be there, primarily composed of the telephone recordings as well as duplicate orders that will tell the story. In addition, it should not have absolutely impact on capital because the moment it was determined that the broker-agent, or customer, or even the floor broker was the one at fault, they could ate the error. Also, incase the error happened at any other place in the process, and then the clearing firm needed to swallow the loss (Jackwerth& Rubinstein, 1996). The function that insurance can perform in reducing the capital impact of operational loss of a firm is highly significant. Transferring a certain risk to an insurance firm can lead to a better performance hence covering diverse losses and prevent critical situation. It has been approved that insurance can be applied as a mechanism to minimize the impact of operational losses for firms like banks, and this means that a specific insurance against risks can result to a low level of minimum capital that is allocated to a given risk category (MacMinn & Richard, 2005). In hard economic moment, organization tend not be affected as such. With the financial crisis, it has been reported on ways firms employ strategies in order to cope up with the difficulties that inevitably follow crisis in economic (Douglas& Browne, 2011 ). Scenario analysis is a strategise tool in making decision. However, it has been applied for most decades in different disciplines, that

Law7 ass1 - Essay Example The opinion basically cites the common law protection against unreasonable charge while at the same time encouraging the values of free trade. Hotels are public accommodations and can only exercise their right to admission to a certain level. The hotels may not refuse accommodation to guests for reasons that are deemed discriminatory. They however have the right to regulate the use of their facilities other than the basic by allowing a certain section of their clientele access to some of their facilities and withholding the privileges so long as the selection criteria does not amount to discrimination by reason of race, origin, nationality, color, religion or Condition. The mode of dressing does not make one a minority. The Unruh Civil Rights aims to protect minority customers from discrimination on the basis of factors such as religion, age, gender, color, ancestry, nationality, disability, medical condition, marital status, or sexual orientation. The hotels in California can therefore legally refuse accommodation to a person dressed in a peculiar manner for instance when the mode of dressing may be offensive to other guests. The same applies to other states and cannot be viewed as discrimination. However, hotels in California and other states may not refuse accommodation to a person on the basis of their dressing if the same boils down to discrimination. An example is when the clothes worn indicate adherence to a certain
