Chapter 4: Mastering Self-Management

I choose this chapter because I understand the importance of self-management. I am also aware self-management has been the skills that I have not been able to master while I know very well that I should. Everybody that is successful in every aspect of life has one thing in common, and that is excellent self-management skills. The core skills that a successful person should have included being able to manage one’s commitments and time. Generating the motivation and capacity to learn new things individually in support of whatever one is engaging in be it work or education. Self-management ultimately enables on to build a personal network.

I learned that working on something else when according to my schedule I should be engaging in some other piece of work no matter how important that thing I am working on is compared to what I have put aside is not ideal and erodes the value of the schedule. I learnt that planning is key to everything including being successful. Self-management is about being aware of my talents and putting them to good use. The opposite of self-management is being unorganized. Being unorganized involves being untidy.

I learnt that I am a huge procrastinator and that is the biggest enemy to good self-management. I learnt that not putting my papers and in a manner that is organized means I am poor in self-manage and I am an untidy person in that aspect. I also realized I had bad behaviors that I was not aware of and thought that was just part of life.

Self-management is a topic that allows students to identify the problems that hinder them from developing positive skills in daily life. Being able to plan well reduces unnecessary fatigue and enables a student to anticipate the next assignment. Self-management management can help a student juggle through all the important tasks in their life and ensure nothing is out of place. Being able to handle every crucial piece of work and on time is what translates to success.

Chapter 6: Gaining Self-Awareness

I choose this chapter because I feel it has been the most helpful and has allowed me to interact with my subconscious. It is very eye-opening to know that there are intentions that one does without being aware of them which led them to make choices that sabotage their success. This topic has also a great connection with Self-management as it also involves planning and taking effective actions.

I learnt that there are self-defeating habits in the subconscious that hinder the success of students with great potential. This is called self-sabotage and involves making choices that go against the objectives one has set and dreams. Learning that people can be their own greatest obstacle is very fascinating. I learnt that the first and most important thing is accepting self-responsibility. Learnt about the scripts that one should be aware of and rewrite them if some derail us from the course.

I learnt that I am lucky enough to be positive. I also became aware of my ability to empower myself and overcome outdated scripts that do not add to my life in a way that is positive. I also learnt that I do not take too much of my energy focusing on issues that pull me back and do not give such things space in my life which is a pretty amazing attribute.

By being aware of self-defeating habits, students are able to change the narrative and consequently their life for the better. Students can plan self-consciously by prioritizing time to research better habits and aspects that add to their lives.

I believe that I do pretty well in this area. However, I am the kind of person that believes in their being space for improvement in everything. Life is about getting better and better and since I am not yet where I should be I believe that I am still growing and improving in this area is crucial.

Adventures of Sherlock Holmes by Doyle, Arthur Conan

Introduction

The Adventures of Sherlock Holmes was written by Sir Arthur Conan Doyle in 1892. The first narrative, A Study in Scarlet, was published the in 1887. Doyle abandoned his career as a physician five years following the production of Sherlock Holmes. He wrote numerous short narratives and a few Sherlock Holmes books in forty years. Doctor Watson and Sherlock Holmes were created by Doyle in England, at a time he has legal problems.

BODY

The Adventures of Sherlock Holmes attracted numerous readers, since it was well written. During its era in The Strand, the people took pleasure in obtaining a new chapter of this book every week. Doyle is attached to Sherlock Holmes since he was also adventurous as well as a detective. The Adventures of Sherlock Holmes as a mystery novel brings out the covetousness that money grants to people.

Theme. Sherlock Holmes utilizes a peculiar category of technique in his work. This is a technique that distinguishes him from his occasional contemporaries in the police force, as well as from the ordinary man. He refers to this technique as deduction, and the utilization of deduction is a universal theme, running in every Sherlock Holmes narrative. In common sense, deduction is the conjecture of a conclusion from grounds such as the supposition of the actuality that Socrates is mortal. This is in regard to the knowledge that, Socrates is human, and that every human being is mortal. This technique is different from induction, which entails gathering separate facts or instances, and trying to draw normal conclusions from them that usually hold but that is not rationally expected to hold.

Conclusion. Sherlock Holmes is undoubtedly one of the most adored figures in the record of mystery fiction. The character’s legacy is timeless, since the book has been repeatedly featured even in other forms such as movies. In spite of the very specific geographic and temporal setting, the Holmes stories embrace eternal qualities that defer their anachronistic characteristics. Holmes is a figure is loved, and known by countless people, whether they have read the narratives or not. His mannerisms, dress code as well, as his character, have been emulated by numerous characters in similar stories. Holmes is known to arrive at his conclusions by means of the technique of scientific deduction. The author, readers, as well as the publishers played a role in the generation of Sherlock Holmes’ cultural phenomenon. It is essential to acknowledge that the context of the Holmes narratives requires that the author, readers, as well as, the publishers be understood.

Personal Thoughts of Book. Numerous sleuths have risen and disappeared into oblivion since Doyle’s Holmes narratives. However, Sherlock Holmes’ character continues to attract readers as well as movie producers. The majority of people think of Sherlock Holmes as a true historical figure, a legendary figure that would rank on the scale of legends such as King Arthur and Robin Hood. The Adventures of Sherlock Holmes would pass as an incredible literary accomplishment for a mere Victorian doctor who desired to change humanity with words, for which he ought to be given and must accept credit. 

SUMMARY

Sherlock Holmes as a cultural phenomenon has grown far outside the limitations of the sixty stories around the canon. Yet the ambiance of 19th century London, the meerschaum pipe, science of deduction, and the deerstalker cap have survived as symbols of a character that lived his existence in the now remote past. It is amazing given the ubiquitous nature of this cultural icon. He still stirs up passion and mystery a century following his creation.

Muammar Gaddafi, the Fallen Leader of Libya

Muammar Gaddafi is among the world’s leaders who have served the longest in their countries. He ruled Libya and eventually gained repute as the longest rulingf dictators among the African countries ruled by dictators. He ruled for four decades before his people had enough and organized large demonstrations and protests that eventually led to his capture, overthrowing of his government and death. Gaddafi was born a Bedouin tribesman and went to school at a military college. Immediately after college, the young Gaddafi set out to make plans of how to overthrow the then Libyan Leader Idris. He eventually accomplished his goals and took over the government in 1969 after a subtle coup. The leader was then only 27 years of age. He was a colonel then and in the early 1970s he developed some philosophical pretentions, which led to his publishing of a book known as the Green Book of Political Philosophy and Leading Libya in a path of Islamic Socialism. The young president managed to achieve this, and persuade his audience of his ‘good’ intentions with the African country while ruthlessly suppressing opposition and rebellion (Menon1).

In the 1980s, however, some other rulers were able to see through his intentions. One of these was the then US president Ronald Reagan who identified Gaddafi as the ‘mad dog’ posing as president in the Middle East. President Reagan then ordered the 1986 Tripoli bombings, which took the life of the Gaddafi’s daughter. Two, there was a bombing of a passenger airplane in Scotland, and it was thought that terrorists from Libya were involved. This lead to the international sanctions on the country and its president throughout the 1990s. In 2003, Libya eventually came clean and revealed that it was responsible for the bombings, something that led to easing of the sanctions and an improved relationship with the United States (Skynews). All through, Libya’s president remained rigidly in power and established a reputation of an eccentric and shrewd dictator. In 2011, protests and demonstrations occurred in the country and his shrewdness took on another level. He attacked his own people leading to an allied team from both the US and Arab world to launch attacks against the country. Rebel forces overrun the capital city late 2011 leading to the president to escape. However, the rebels were able to capture him two months later after he was wounded near his Sirte hometown. The dictator was wounded, and he later died of injuries (Menon1).

This paper is a discussion of this famous leader, who was largely known for his harsh ways of leadership and for his shrewdness and dictatorship. The paper will discuss his career as a ruler leading one of the world’s oil- rich countries, and show the happenings that eventually led to the overthrowing of his dictatorship and rule, highlighting some of the problems that led to the 2011 protests and how the late president dealt with them.

Libya’s fallen dictator and leader Muammar Gaddafi who had been president of the oil- rich African country for more than four decades was killed late 2011 in his hometown in Sirte after hiding for around two months. The NTC or the ruling National Transitional Council drove the 69 years of age leader and his forces out of the country’s capital city, Tripoli. The leader had organized and was leading resistance and rebellion against his enemies from an unknown place in Libya for those two months he had been in hiding. Earlier in the year, the international Criminal Court had directed that the president’s son, Saif al- Islam be arrested together with the nation’s intelligence chief, Abdullah al- Senussi. The two were being charged with crimes against the Libyan people. The two were accused of murdering and leading violations and criminal acts against the Libyan people who opposed the rule of Gaddafi.

In early February of 2011, the Libyan people motivated by the anti – government protests named the Arab Spring in a number of Arab countries, took to the streets in one of the largest cities in Libya, Benghazi, to voice their opposition and displeasure with their president who had developed a reputation of being independent in speech and actions (Schwartz).

The leader was in power for about 42 years one of the longest presidential terms in the world. During his rule, he provided the 6.5 million Libyan populations with the basic living amenities, but during this time won over the central tribesmen in the nation through power and money so as to ensure his dominance. When gradually misusing the nation’s vast wealth, Gaddafi was blamed for limiting and regulating the salaries and wages for his people, ignoring investments in infrastructure, and civil structure, and leaving unemployment rates extremely high. Muammar joined the Benghazi Military University, later joined the Libyan army in 1965 and was later sent for more training in 1966 to the British Royal Military Sandhurst (Yan 1- 3).

The rule of Muammar Gaddafi began in late 1969. During this time, the then young junior officer incited and led some of his colleagues in the FOM, Free Officers Movement, and organized a bloodless coup that overthrew the rule of the then leader of Libya, King Idris. The king was not present at the time as he was undergoing treatment in Turkey. After overthrowing the government, Gaddafi then set up the Libyan Arab Republic. As soon as he achieved this, he became the commander- in- chief of the Libyan armed forces, as well as, the Revolutionary Command Council chairperson. Between 1970 and 72, he served as the defense minister in the country and later became the prime minister. In 1977, he established himself as the Libyan Revolutionary leader, gave up all of his administrative roles in 1979, and retained the title as the revolutionary leader of the country (Yan 1- 3).

Starting from the 1970s, the leader became fed up with the earlier occupation by colonialists and the monarchial corruption and made the Libyan people the key beneficiaries of free health care, education and subsidized the costs of transport and housing, with the aid of the huge revenue the country was getting from its oil industry and the country’s relative small population. However, he also enacted a strict governance based on Islamic riles, banning such things as alcohol and gambling, and he implemented a system of Islamic morals. The main cities in the country like Tripoli began to boost of magnificent hotels and buildings, turning into a destination of choice for businesspersons and tourists from all over the world (Libya and Muammar Qaddafi, 40 years on).

However, all efforts Gaddafi was making were soon proved insufficient to diversify and quicken the growth of the country to a larger extent, as he was hung up to dominance and dictatorship, and, in this wake, he crippled the major civil unions and independent trade unions along with numerous budding political parties. He eventually crippled the state apparatus and started ruling his people with more power, power much more than that entrusted with a president (Libya and Muammar Qaddafi, 40 years on).

With time, the country’s pride in such social systems as health care was long gone. It was said that more and more individuals were seeking medical aid from health care systems of other countries such as Egypt, Jordan and Tunisia after realizing that the health system in their own country was both unreliable and inefficient. This countrywide distrust of the healthcare system was suspected to have stemmed from more than 500 wrongful HIV infections of young children from contaminated medical tools in Benghazi, in 1999 (Libya and Muammar Qaddafi, 40 years on).

When the people tried to hold protests and demonstrations against this injustice, they were met with unbelievable deviance. To the president, these protests were insignificant when compared to the numerous wars and planned assassinations he had survived over the years. His defiance continued to grow especially after the 1988 bombings of a plane in Scotland, an event where Libyan terrorists were implicated. The tragedy caused the deaths of 270 people 189 of whom were Americans. The attack was thought as among a number of violent responses in the 1980s between the states sponsored terrorist groups in the country and the United States. The Libyan leader refused to turn over the terrorists until 1999. Four years later, the president assumed responsibility of the bombings but never apologized for the deadly attacks. In 2009, the defiant president welcomed one of the suspects of the attacks at the airport once he was released from a Scottish prison, an act that once more angered the west (Yan 1- 3).

At times, however, the president assessed a number of situations and made compromises especially after being punished with years of sanctions by most western nations and the United Nations. To survive his political career, the leader was quick to dissociate himself from the September 2011 attacks by denouncing the attacks publicly. In 2003, he also announced that he and his country had abandoned its programs and projects of building and using weapons of mass destruction (Libya and Muammar Qaddafi, 40 years on).

Although the president usually set up official people’s committees, he practically gave them limited power. People who thought otherwise or who opposed him and his ideas were killed or sent to prison. Most of these political prisoners simply disappeared or were tortured for years. The media were no exception, as it was under tight control and watch by the colonel. His ideologies are presented and reflected by the ideas and arguments of his book, in which he establishes a mixture of socialism mixed with Islamic principles and capitalism (Bazzi 1). The president was also famous for having forty female soldiers for his bodyguards who he picked. He never wore suits instead opting for stylish clothes inspired by Arab designs with sunglasses. He always welcomed his guests in tents that were heavily guarded instead of palaces and state houses (‘Gaddafi: Africa’s king of kings’).

Although Muammar Gaddafi considered himself as an intellect person, most of his remarks and ideologies highlighted his intolerant and at times not so intellectual attitude, and this was one of his few constants during his rule. Some of his most outlandish claims and arguments included referring to the HIV as a peace virus, an arguing that people should not worry about the virus if they were straight. The president once cancelled all school vacations so that the young children could be educated of his ideologies when they were supposed to be enjoying their holiday. The president even believed that the 2008 H1N1 virus was some sort of mass destruction weapon that some foreign military had developed (‘Gaddafi: Africa’s king of kings’).

Muammar Gaddafi was married two times. He met one of his wives while admitted to a hospital. She was a nurse at the hospital. With the two wives, Muammar had eight children with only one being a daughter. Two of his eldest sons eventually became prominent politicians, and it was widely rumored that the two struggled on who would inherit the power after their father. He also had two other children whom he adopted one was claimed to have been killed in the US military attacks (‘Gaddafi: Africa’s king of kings’).

The president was also connected to numerous abominable acts. Besides being connected to numerous terrorist attacks and activities, Gaddafi was also accused of violating numerous basic human rights and freedoms. The Human Rights Watch argues that numerous people, in hundreds, were imprisoned and treated inhumanly for opposing the powerful leader, and some of these prisoners were even killed. Disappearances, deaths and abductions, were a common feature during Gaddafi’s rule (Salak 1). However, these crimes were nothing when compared to one of the worst crimes he ever committed during his rule, the murder of 270 people in the Scottish flight he was involved with the bombing (‘Gaddafi: Africa’s king of kings’).

Although the economy of Libya was opened up to investments from foreign nations and investors in the past, there was little done as reforms. Most of the Libyans believed that their president had used most of the resources of their nation to amerce wealth for himself, family and close allies. The country is one of the richest countries in oil resources in the world and its economy still remained like any other economy in a poor African state. All the resources the president acquired went directly to his pockets or those of his family or those he wanted to bribe for support (Libya and Muammar Qaddafi, 40 years on). Most Libyan people felt that they had not in any way benefited from the vast gas and oil resources in the country, with corruption rife and poor public services. Although the country is among the oil and gas- richest nations in the world, its people still remain poor and live under poor living conditions, with the larger proportion of his people living under excessive poverty. The people have not received half the wealth and riches that the president has accumulated for those forty years he has been in power. Experts have estimated that Muammar Gaddafi may have accumulated a fortune of more than 60 million dollars over the years he was president (‘Gaddafi: Africa’s king of kings’).

The dictator’s problems began with the unrest in Egypt and Tunisia. When the protests and demonstrations started in these two countries in the start of 2011 it was obvious that they would spread and consume other Arab countries like Libya. His defiance led him to believe that he protests that had spilled over to his turf would go away in a few days. However, having found that the demonstrators were unusually unrelenting and determined, the president resorted to force and dictatorship, and he launched indiscriminate attacks on his own people, which eventually claimed significant civilian lives. However, these violent clashes between the protestors and the Gaddafi forces simply sharpened and increased the antagonism and pushed the nation to the brink of a new age civil war (Blundy and Sicker 1-2).

When matters seemed difficult and people seemed determined to accomplish their goals some government officials stepped down, and picked up weapons, and joined up forces with the protestors and rebels to fight the regime of the dictator leader Muammar Gaddafi. Nevertheless, the rebel groups, with only a barren arsenal and without uniform, were no authority or rival to the government forces and soldiers. However, a resolution established by the UN in early 2011 won reprieve for the rebel troops. The UN resolution was proposed by Britain, Lebanon and France and was intended to protect the Libyan civilians. The resolution demanded an immediate truce, authorized the development of a no- fly zone over the nation, and strengthened the arms restriction. Yet, the resolution allowed for the legal foundation for intervention by the military in the domestic conflict of the troubled Libya (Blundy and Sicker 1-2).

As the Gaddafi forces failed and refused to observe and agree with the ceasefire, as it was announced, Britain, France and the United States began in early 2011 airstrikes that were meant to motivate Gaddafi to surrender. May 2011, NATO finally assumed command of the military operation in the country after its single Muslim member, Turkey, agreed with the action. Daily targeted raids eventually claimed the lives of the leader’s son Saif and three grandchildren, events that forced him to hide in a number of different places. In mid 2011, the NTC announced that they suspected that Khamis, another son of the leader, had been killed in the attacks. In addition to this, the Algerian government indicated that members of the family of the president including his wife, two sons and a pregnant daughter had fled to Algeria (Walt 1-2).

It was not long before the leader was captured somewhere near his hometown after he had sustained injuries after an attack. The chains of events that led to the death of the ousted Libyan dictator Muammar Gaddafi are still very much debatable and under dispute. However, numerous videos surfaced soon after that showed the leader alive on Thursday, a few hours after he was captured. Moments later, other videos came up showing pictures of the dead president and others showing him being tortured to death. It was said that the former Libyan leader was dragged by rebel troops from a drainpipe after an air strike by the NATO. In another video, he is seen wiping blood off his face in a daze as rebel troops surround him, firing guns in the air and shouting some slogans (Jaffe 1-2).

Conclusion

Muammar Gaddafi is among the world’s leaders who have served the longest in their countries, assuming leadership in Libya for more than 42 years and in the wake of his regime coining a reputation for himself as being a dictator, shrewd, arrogant and defiant. He led his country to a series of developments, all of which were overshadowed by his shrewd manner of governance, and the level of corruption he allowed the government offices to be run with. Eventually, the people had enough of his leadership and took to the streets emulating their Arab brothers in Tunisia and Egypt, events that led to the death of the leader. All in all a new page is expected to be unveiled in the Libyan history, yet it is not clear whether this page tells of an awful or delightful story. However, it is apparent that the proceedings that led to the terrible war will be cured with time and that the country will assume integrity and success.

Mulan Joins the Army

Mulan Joins the Army

Course

Mulan joins the Army is indeed a patriotic play that is based on a filial woman, Mulan who manages to save her country from barbarians’ attack. Mulan seems to believe in her abilities and she is further driven by the need to fight and die for her country. She finds courage to amazingly represent her sick father at the war front after Mu shu refuses to join the military. Mulan hides her gender identity and presents herself as a man just to fight for her country by resisting foreign invasion. Her quality job earns her a place after she is promoted to sergeant (Kwa & Idema, 2010).

Similarly for the sake of the country Liu who is a close friend of Mulan identifies her identity but goes ahead to hide. Mulan is actually transformed from a father’s sympathizer to a savior of her country. This story tends to remind us about soldiers who sacrifice everything just to save their nation. Mulan goes beyond the traditional women culture in China to take up an opportunity in the military. Fighting against a nation’s enemy as was the case in the play is a show of unity and patriotism especially when it is done at the expense of other things such as gender norms and abandonment of family (Kwa & Idema, 2010).

Mula joins the army further shows a sign of cultural transformation by introducing an aspect of female patriotism. New emphasis on patriotism is achieved by depicting Hua Mulan as a true patriot who is ready to risk her life for the sake of her country. Mulan says according to Kwa & Idema (2010), “I risk my life for the sake of the country” (p. 43). Mulan has further proved that women’s role is not only to care for their families back at home as was traditionally thought. Women, just like men can take active role in the military to save their country. It is really impressive and encouraging to see a woman sacrificing herself to go to war and even hides her identity just to accomplish her task.

Adverse reporting events in medication

Name:

Institution:

Adverse reporting events in medication may be explained as: “Any one of the many untoward medical occurrences in a patient or either a clinical investigation subject administered to a pharmaceutical product which never necessarily has to possess a causal relationship with treatment. In clinical trials, there is always a distinction between adverse events as well as serious adverse events. In general terms, any event that causes death, or permanent damage, requires hospitalization or causes birth defects is considered a serious adverse event. The results of the trials are usually included in the labeling of the medication in order to provide basic information for the patients, as well as prescribing physicians.

Adverse effects are always required by law to be reported, and also researched in all clinical trials and also included into the patient information that accompanies medical devices or drugs for sale to the public. Investigators specializing in human clinical trials are usually obligated to report the events in clinical study reports. Research is of the opinion that the events are usually inadequately reported in all publicly available reports. This is because of the lack of the data and the uncertainty about methods of synthesizing them, the individuals conducting systematic reviews as well as meta-analyses of all therapeutic interventions who unknowingly overemphasize the health benefit. To balance off the overemphasis on benefit, doctors and researchers have called for complete reporting of harm from the clinical trials.

There is the lack of certainty that the reported event was due to the product. Thus, it is not required that a causal relationship between product and event be proven, as reports do not usually contain enough detail to properly evaluate a particular event.

Advantages and limitations of ferrous materials in engineering applicationThe main component of ferrous metals is iron but it also contains other metals and elements though in small amounts. These metals are magnetic since they have a large iron content that attracts a magnetic field. There are several advantages of using ferrous materials in engineering applications these include; the raw materials for their production are found abundantly on the earth’s crust (Callister,2000).Secondly they can be produced easily through an economical extraction process, alloying, refining as well as fabrication techniques. Finally they are versatile when it comes to physical and mechanical properties. There are also some limitations when using these ferrous materials in engineering application and these are; the fact that they have a relative high density, they have a low corrosion resistance and hence they require coating and finally they have low thermal and electrical conduction properties.

1B.Advatages and limitations of non-ferrous alloys in engineering application

Non-ferrous metals are alloys with no iron in them. Their properties differ from those of ferrous metals. Their properties are a result of the metals that are not present in ferrous metals but are present in them. Some of their advantages when used in engineering applications are that they are easily fabricated, their ductile nature, they have a light weight, they are corrosion resistant and they are very strong at temperatures which are elevated (DeGarmo, Black &Kohser,1997).There are also some limitations to their use and they include a low modulus of elasticity, they are expensive when compared to iron and steel, they have a high density, they can be susceptible to corrosion in certain environments and their electrical and thermal conductivity is medium (Crook &Farmer, 2002).

1C.Advatages and limitations of polymers in engineering applicationThese are substances that are made up of a mixture of many compounds. Their properties are therefore dependent on the rate of loading as well as temperatures. Polymers have many properties due to the mechanical behavior that they posses. Therefore there exist different polymers each with different characteristics. Polymers are advantageous when it comes to engineering applications because they are light in weight, resistant to corrosion, formability, have a low energy content, versatility in design, range from soft to hard and they have optical properties. The limitation of using polymers is its low thermal conductivity.

1D.Advatages and limitations of using ceramics in engineering applicationCeramic are materials whose nature and properties is determined by they bonding that is found within the atoms. These are traditional materials made from substances that occur naturally as well as those which are highly refined or chemical, magnetic and electrical applications. Ceramics are advantageous in engineering application since some of them have high thermal conductivity while other have a low thermal conductivity. They are chemically stable in a wide range of temperatures. They resist high temperatures, high melting point and chemicals (Lahiri &Majumder, 2012). There exist ratios that are high between weight and strength. They also have a low rate of corrosion. When it comes to their limitations they posses low toughness as a small crack leads to their eventual fracture. It is quite difficult to make predictions of their strength of interfacial bond .they have a limited repair ability when damaged.

2A.Selection of ferrous metals in engineering applicationFerrous metals posses different properties that are put into use in various industries. They have different specifications when it comes to mechanical and physical properties. For instance iron mild steel is malleable and ductile and hence used for production of bolts, nuts and screws. Iron can also be used as tool steel since it is hard and very ductile hence used in producing shears, drills and hammer heads.

Alloy steels have high hardenabilty compared to plain carbon steels. This is because alloy steels are made up of many elements and hence they have improved properties. The alloy steels are stronger, resistant to erosion and have improved harden ability ( DeGarmo, Black &Kohser,1997).One the other hand carbon content in the plain carbon steel determines its strength since carbon content is inversely proportional to ductility. Therefore a low hardenability results from a decrease in plain carbon. This means that the quality of the steel go down through impairing in low and high temperatures resulting to a loss in embrittlement and strength. Therefore if other elements are added to steel then their hardenability will be improved (DeGarmo, Black &Kohser, 1997

2B.Non-ferous alloys in engineering applicationThe non-ferrous metals have many properties but there are some of the non-ferrous metals whose applications are more suitable than others. Aluminum is suitable in Aircraft industry, road signs, cooking utensils because it is light. Aluminum use is increased in motor vehicles, engine blocks where the low weight increase fuel economy. Copper is a good electrical conductor hence used in electrical wiring. Zinc is used in decorative articles since it is ductile and malleable in hot and cold temperatures. Lead is highly resistant to corrosion hence used in mild steel as a protective coating.tin can be used to coat mild steel hence put into use in canning industry (DeGarmo, Black &Kohser, 1997).

Non-ferrous alloys exist in both cast and raw forms. The principal behind the existence of these two forms is cast non-ferrous alloys need high temperatures to be melted and then the liquid is poured into a mould and cooled before other parts are added. These alloys are thus brittle and hence they can not be easily formed through deformation. Wrought non ferrous alloys are shaped through pressing and shaping and hence this makes them more tensile and stronger. They can thus go through mechanical deformation.

2C.Polymers used in engineering applicationPolymers have specific properties from their families like thermosets, thermoplastics and elastomers alongside general properties. Due to their characteristics they can be applied in materials which require moderate strength, low thermal and electrical conductivity, variety of colors are light in weight, and are easily fabricated. Their common use is household appliances such as containers. Those polymers that are pliable and soft can be used as materials for cushioning. Other can also be used for the insulation of electrical appliances.

There are two types of composite materials namely dispersion strengthening and fiber strengthening. The dispersion strengthening materials have a uniform dispersion of some substances that give motion of dislocations plastic in nature and hence reducing the plastic deformation in a solid. On the other hand fibers strengthening entail the inclusion of fibers with plastics and hence this combination has an influence on the strength and thermal conductivity dependent on their ration (Vernon, 1992).

2D.Ceramics in engineering applicationCeramics have many properties that can not be found in metals or plastics. They are used as non-reactive materials in chemicals erosive and corrosive fluids of low temperatures and corrosive gases and melts that have high temperatures. They can be used for thermal, optical, electrical and magnetic applications. They are used in mining and chemical engineering since they are non-reactive to erosive or corrosive fluids. They can also be used in heat engines and exchangers as they can resist thermal shock, corrosion and oxidation that involve high temperature (Richerson, 1988).

Ceramics are of two types industrial or engineering and domestic. Engineering ceramics is whereby ceramics are used for making materials in industries like automotive industry. On the other hand domestic ceramics are used for constructing as tiles for floors and walls in interior design.

3A.surface hardening treatmentsCarburizing is a treatment method for making metal surfaces hard using heat. Heating metals in presence of materials that contain carbon, leads to its absorption with the metals. Carburizing can lead to increase in the surface hardness, carbon content on the surface, wear resistance, tensile strengths and change its volume as well as making it gain growth (Vernon, 1992).

Nitriding on the other hand makes surfaces harder through spreading of nitrogen on surfaces of metals using heat. Nitriding results to increased surface hardness, wear resistance, yield limit and reducing density of surface and elongation, carburizing is more suitable as a method of hardening surfaces as compared to nitriding (Vernon, 1992).carburizing also results to greater depth and hardness as compared to nitriding .carburizing is applied in gears, and bearings while nitriding is applied in valve guides and seating’s.

3B.Hardening of steel surfacesSteel surfaces need to be carburized since it is a suitable method for some steels particularly a steel alloys that contain 0.5% carbon while quenching and re-heating is used for steel that 0.4-0.5% carbon and 0.4-0.8% cast iron.

3. C erosion corrosion

Metals undergo erosion corrosion when they are subjected to mechanical action like suspension of particles which are insoluble and hence they deteriorate as a result of the mechanical force. In instances where erosion factors hasten corrosion the attack is referred to as erosion corrosion (Schweitzer,2010).Erosion corrosion can be prevented by lowering flow rates of fluid path materials that contain high temperature fluids in them. Reduction in velocity, turbulence elimination and designing piping systems properly also reduce erosion corrosion (Schweitzer, 2010).

3D.Classes of stainless steel.Ferritic stainless steel can be either ductile or brittle nature when their temperatures are reduced. They are hence used in thin walls due to their brittle characteristic. Martensitic stainless steel is strong and resistance to corrosion. It can therefore it can be put into use in light weight structures. Austenitic stainless steel is used in all temperatures from low to high. At low temperatures they are very tough while at high temperatures they are resistant to oxidation. They can therefore be used as non-magnetic metals (DeGarmo, .Black &Kohser, 1997).

3E.Wear processesAdhesive process involves the deformation of plastics in very small fragments on the surface after a frictional contact. It frequently occurs sue to the shearing at a particular point of contact. Abrasive process involves removing materials from a surface by the use of hard particles which are forced and moving against the surface of solids. Erosive process occurs as a result of an impact of solid or liquid particles on the surface of an object. (DeGarmo, Black &Kohser, 1997).

3F.Mechanisms of abrasive processThere are several mechanisms involved in abrasive wear and they are micro-plouging whereby materials are cut by debris in the form of flakes and used of ductile materials. Micro-cutting involves wear debris being cut or removed using sharp grit .micro-fatigue results from cycling loading from friction whereby the surface is deformed by grits. Micro-cracking involves high load of grit moving across a surface resulting to the cracking of the surface (DeGarmo, Black &Kohser, 1997).

4A.stages of fatigue failure processCrack initiation is the first stage where a crack forms at a point of high stress .this is followed by crack propagation whereby the crack continues to grow at that area. The third stage is final failure whereby the crack reaches a critical size due to the continuous growth of crack.

4B.variables affecting fracture toughness and appearance of materialsTemperature increase results to dislocation of metals hence the yield strength is lowered. Surfaces of ductile metals thus appear dull and fibrous. Ductile brittle transitions appear cleavage or granular. Notch surety is another variable whereby is notch or cracks are present, a triaxial tension stress occurs adjacent to the notch or crack when a load is put. This results to formation of a brittle fracture incase there is prevention from plastic deformation. Thickness is a variable that is independent as the toughness of the fracture depends on how thick a material is. The materials thickness is inversely proportional to the toughness of the fracture (Callister, 2000).

4C.Selecvtion of creep resistant alloysSuper alloys have good properties like good mechanical strength as well as creep resistance and hence they have slow movements towards deformation when they are stressed. Therefore there are factors that should be considered when selecting super alloys and these are the cost, macinability, high tensile strength an high stress levels at high temperatures for periods that are extended.

5A.Conditions for underbead crackingUnderbead cracking occurs in welded steels as a result of various conditions which are existence of a heat affected zone crack forming adjacent to the fusion line. Another condition is presence of hydrogen in weld zone. This type of cracking occurs mostly in alloy steel.

5B.reasons for pre-heating and post heating welded steel component

The three reasons are slowing down of cooling rate, reduction of shrinkage stress and distortion of wells and finally the promotion of fusion and moisture removal.

5C.changes in HAZ of cold worked

A high dislocation is given by cold worked. The material is made brittle as a result of low temperatures. They are given a finer grain as well as a decrease in the amount of boundaries that are in existence between the grains found in their surfaces. Cold working is therefore a process whereby metals undergo plastic deformation below recrystallization (Huda, 2009).

Literature Review

Different engineering materials

The engineering materials available for use in different applications are wide in range. These materials all have particular properties and characteristics linked to them. There are also various advantages and disadvantages for each of the materials .there is a detailed discussion of the definition of these materials and structures

Metals are of two types ferrous and non-ferrous which can be put into application in different ways. Ferrous metals are widely used due to the large quantity of iron in the earth’s crust as well as their production in an economical extraction (Callister, 2000). The element iron is fourth most plentiful on the crust of the earth and for a very long time it has been used as a basic metal in engineering (DeGarmo, Black &Kohser, 1997). Nonferrous alloys are used for high resistance to particular wear apart from abrasion or resistance to wear in environments where corrosion is too high or beyond ferrous alloys service temperatures (Crook &Farmer.H, 2002).Nonferrous metals have an important role in modern technology due to their large number and their wide variety they provide a range that has no limit of properties to design engineers (DeGarmo, Black &Kohser, 1997).

Apart fro ferrous and non-ferrous metals there are also other engineering materials and these are ceramics and polymers. Ferroelectric liquid crystals that are stabilized by polymers are a representation of functional materials that can be applied in areas like privacy windows, optical shutters, photonics that can be switched on and dynamic holography (DeGarmo,Black &Kohser,1997).they are low in density, their tooling costs are low, resistance to corrosion, and versatile in design. Ceramics include both traditional materials from heating of substances occurring naturally and those materials that have undergone refining and synthesis for material’s that are used for modern mechanical, chemical, magnetic optical and electrical applications (Richerson,1988).It has good resistance to thermal shock as well as oxidation under high temperatures hence used in development of heat engines and exchangers( Richerson,D ,1988).domestic ceramics have been put into use in household products.

Abrasive materials are those materials that are hard and can cut or cause abrasion to other substances DeGarmo, Black &Kohser, 1997).abrasive systems involve flow of mineral ore through feed chute into upper portions of the zone for crushing which is made up of two plates one that is stationery while the other is in motion. Rock chunks make their way into the top and their sizes reduce every time there is cycling of jaws towards each other.

Chapter 3: Reality and Being

Chapter Three of the book “A Text with Readings,” discusses “Reality and Being,” it opens up by trying to answer the question regarding what is real. Therefore the discussion fall in the realm of metaphysics. To learn more on what is reality one has to understand metaphysics. Metaphysics is one of the branches of philosophy, and it tends to examine what reality is, as well as being, and also what matters most to individuals. Consequently, there exist some metaphysical outlooks which include analytical philosophy, materialism-idealism besides the reactions of pragmatism. Materialism considers reality as matter. Materialism observes matter as the decisive component of existence. Many individuals reality comprises of only physical objects while excluding nonphysical objects. Also, they regard what is real to be substantial, significant, matters make a difference and have to be attended to. According to Nozick, for something to be real, it must have some value, meaning, weight and also some importance. Horbes who is an early materialist also contended that only physical objects are real. Idealism is also used to explain more about reality in distinguishing whether it is material or nonmaterial. As illustrated, idealism holds that reality is immaterial for example things like one’s idea, spirit and also the mind.

Berkeley who is an absolute idealist challenged the concept whereby most individuals usually contemplate that the world around them is generally made up of solid stuff. He maintained that since individuals’ minds typically perceive their specific ideas, therefore only their minds, as well as their thoughts, can be real. However, his ideas face a lot of criticism from critics who argue that individuals never recognize their ideas or sensations and instead they tend to perceive the things that are around them and not the thoughts and perceptions in their heads. The critics further explain that idealism that Berkeley tends to incline to encourages an extraction from the actual world and is a haven from secular glitches. Therefore they claim that this idealism will result in individuals neglecting real as well as pressing social concerns. The two types of idealism are subjective and objective. Subjective idealism states that reality comprises of one’s mind together with its ideas.

On the other hand, objective idealism claims that reality comprises of an ultimate mind that generates an impartial world of thoughts that never depends on one’s mind although it typically depends on God’s mind. Therefore in general, idealists maintains that reality comprises of minds plus their ideas. All the discussed idealists are referred to as the Western philosophers. However, there exist other philosophers for example from India who believes in Eastern idealism. The Indian philosophy, for instance, has been seen as a home to several philosophers like Vasubandhu. Vasubandhu believed that all the individuals’ experiences of things involve only the sensations in an individual’s minds which disregard the existence of external objects. According to him the ostensible existence of the outer world is only an illusion just the same way as a dream. Also, he argues that when the meditation arouses the individuals, they will realize that the exterior world is an illusion in the similar way they know that a dream is only an illusion when they wake from their sleep. In some instances, Vasubandhu’s opinions regarding idealism are similar to Berkeley’s opinions but differ in other instances.

In the chapter, other issues are well discussed concerning reality and being. They include things like; Reality in pragmatism, reality plus reasonable positivisms and antirealism. Pragmatism seems to reject all the opinions that lack some practical consequences for individuals’ lives. Logical positivists typically base their arguments on the working of the language. They argue that metaphysics is grounded on the linguistic confusions. Moreover, the chapter explains more about reality by answering the questions; are freedom and time real?

Chapter 2: Class Activity 1-Deinstitusalization Discussion

What are the ethical issues of forced treatment and free choice?

Forced treatment and free choice is based on four principles; beneficence, respect for the patient’s autonomy, nonmaleficence and justice. Concept of informed consent is applied where the patient makes a decision on free will and in knowledge of benefits of proposed therapy. However, coercion treatment may be used when the principles of beneficence, nonmaleficence and justice contradict to patient’s will.

Discuss in groups, an example of both

Example of forced treatment; A patient, 65 years old, with acute inflammation of the gall bladder who after going through a successful surgery, tries to remove infusions with antibiotics and claims that she want to go home. In this case, coercion may be used since the nurses see it is not right for her to go home as it may lead to poor outcome.

Example of free choice; John, 45 years old, suffering from pneumonia understands that he needs treatment. In this case, he will agree to therapy with antibiotics but not to therapy with antipsychotics.

Does having a mental health issue remove the basic human rights of a person?

No. Unless there is prove that the individual has impaired judgment on treatment needed.
