Research Article - Speech or Presentation Example Additionally, the research has a number of strengths in the research data collection and computation. The research uses the cluster sampling technique known for its cost effectiveness in the identification of the research participants. An effective selection of the research participants gives an effective representation of the research target audience thus authenticating the claims of the new information. The cluster sampling techniques groups similar respondents together thereby making them easily accessible to the researcher. Additionally, the research employs the three different data collection techniques a feature that pools together the strengths of the three techniques thus making the research more effective. The use of a sample representation gains its validity from the impossibility of investigating every member of the public targeted by the research, the researcher therefore defines the research title and formulates a scope of the study. With these, he or she therefore devis es ways of accessing the respondents and using their responses to allude to the rest of similar population. Additionally, the research uses graphical presentation of its finding. This does not only make the research more presentable but also makes the interpretation of the research. ...This develops the information need that the researcher therefore seeks to satisfy by conducting the research. Through the elaborative background, the researcher provides a link between Neurogenic Bowel in spinal cord injuries and the quality of life that such member of the society lead. This descriptive introduction gains relevance for the research and the different methodologies that the researcher uses in developing his arguments in the conclusion. The research had a number of weaknesses too key among which included cluster sampling methodology. Despite being cost effective, the sampling technology hastily generalizes the respondents a feature that makes the research less relevant to the target popu lation. Additionally, the use of the three data gathering techniques is also redundant and makes the research repetitive thus time consuming. The use of questionnaires is largely similar to the use of interview in most cases, the researcher employs the two concurrently which makes the research process more costly and more repetitive. However, the descriptive research methodology that the researcher employs has a number of weaknesses all of which influence the effectiveness of the research findings thus the efficacy of the conclusion statement. This research structure is normally more theoretical in the description of the effects of the research variables in which case are the Neurogenic Bowel in spinal cord injuries and the quality of life. Both of the concepts in this research that constitute the variables are abstract and the researcher does not interpret these into effective mathematically computable variables. The failure by the researcher to achieve this makes the research proc ess less legitimate, the researcher

Tobacco Mosaic Virus Essay Example for Free

Tobacco Mosaic Virus Essay Hosts for Tomatoe Mosaic Virus include tobacco, tomato, and other solanaceous plants. TMV enters the plant cell through minor wounds. The virus can also contaminate seed coats, and the plants germinating from these seeds can become infected. Once TMV enters the cell, the virus particles disassemble in an organized manner to expose the TMV RNA. The virus RNA is positive-sense, or + sense, and serves directly as a messenger RNA (mRNA) that is translated using host ribosomes. Translation of the replicase-associated proteins (RP) than begins. As soon as these proteins have been synthesized, the replicase associates with the 3 end of the + sense TMV RNA for the production of a negative sense RNA. The sense RNA is the template to produce both full-length genomic + sense RNA as well as the + sense subgenomic RNAs (sgRNAs). The sgRNAs are translated by the host ribosomes to produce the movement protein (MP) (30 kDa) and the coat protein (CP). These virus particles are very stable and, at some point when the cells are broken or the leaf dries up, they are released to infect new plants. Alternatively, the + sense TMV RNA is wrapped in a movement protein, and this can infect adjacent cells. TMV uses its movement protein to spread from cell-to-cell through plasmodesmata, which connect plant cells. Normally, the plasmodesmata are too small for passage of intact TMV particles. The movement protein (probably with some unknown assistance) enlarges the plasmodesmatal openings so that TMV RNA can move to the adjacent cells, release the movement protein and host proteins, and initiate a new round of infection. As the virus moves from cell to cell, it eventually reaches the plants vascular system (veins) for rapid systemic spread through the phloem to the roots and tips of the growing plant.

Julius Caesar: The Use Of Suspense :: essays research papers

Julius Caesar: The Use of Suspense Suspense can be defined as the uncertainties the reader feels about what will happen next in a story, or in this case, a play. William Shakespeare incorporated in Julius Caesar three very suspenseful events on which the whole play depends. The first suspenseful event of this play occurs when the conspirators join and discuss their reasons for assassination. Cassius feels that he is equal to Caesar, if not even better that him. Shakespeare builds suspense by using this statement made by Cassius: "I was born free as Caesar†¦/we both have fed as well, and we can both / endure the winter's cold as well as he." Then cassius tries to persuade Brutes to join in on the conspiracy by telling him that it would be honorable to assassinate Caesar. Cassius tells Brutes that the fate of Rome is in trouble with Caesar in power, which helps build suspense early in the play. To convince Brutes conclusively, cassius forged letters and threw them into Brutus's window where he was sure to find them. Shakespeare wrote this statement: "we will awake him and be sure of him. This is a very powerful statement that builds suspense because the reader most likely feels that Brutes will join in and want to assassinate Caesar, yet the reader is uncertain as to whether or not the plan will work. These events are very suspenseful as they lead up to the assassination of Caesar. The next series of suspenseful events that foreshadow Caesar's assassination happen on a very unusual night. One night before Caesar's death there were many strange occurrences the foreshadows darkness in the future. A lioness gave birth in the streets, the dead rose from their graves, fiery worriers fought in the clouds so fiercely that blood drizzled upon the capitol, horses neighed, dying men groaned, and ghosts shrieked and squealed along the streets; all events of this strange night that Shakespeare makes so suspenseful. Also on this unusual nigh, Calpurnia had a very frightening dream that was very suspenseful. The dream was of Caesar's statue emitting blood and many Romans were bathing in it. When the reader reads this he is "on the edge of his seat" finding that he cannot wait to find out what this dream foreshadows. Calpurnia was so frightened by these strange occurrences that she begged Caesar not to leave the house. Shakespeare created suspense by having Caesar speak these words: "and these does she apply for warnings and portents / and evils imminent, and on her knee / hath begged that I will stay at home today.

Key Principles of Management and Leadership

Unit 1 – Key principles of management and leadership Activity 1 a) Though the two terms seem similar on the surface, in reality they are quite different. A great manager does not necessarily make a great leader, and a great leader does not necessarily make a great manager. Management controls or directs people/resources in a group according to principles or values that have already been established. Leadership is setting a new direction or vision for a group that they follow, i. e. : a leader is the spearhead for that new direction.The manager uses a formal, rational method whilst the leader uses passion and stirs emotions. People naturally and willingly follow leaders due to their charisma and personality traits, whereas a manager is obeyed due to the formal authority vested in him/her. As a result, people tend to be more loyal towards leaders rather than managers. Managers supervise employees. They make plans, delegate responsibilities, and coordinate activities. Their goal is to create something that is definable and repeatable. Leaders are focused on bringing about innovation and change for the company.Their primary role is to inspire people and to motivate employees. They are focused on change. They create a sense of vision, hope, and alignment among employees. An organisation cannot thrive without a manager, and it cannot thrive without a leader. Leadership and management must go hand in hand to be successful – both in corporate and casual settings. They are linked, and complimentary to one another. Managers will:Leaders will: AdministrateInnovate MaintainDevelop Focus on systems and/or structuresFocus on people Rely on their controlInspire trust in people Hold short range viewsHave a longer range perspectiveAsk ‘how’ and ‘when’Ask ‘what’ and ‘why’ Keep an eye on the bottom lineKeep an eye on the horizon ImitateOriginate Accept the status quoChallenge it Be a classic good soldierBe his/her own person Accept realityInvestigate it b) Management encompasses 5 functions which are planning, organising, staffing, directing and controlling. Planning – Planning gives management the ability to logically come up with different strategies to make sure that the project ends in success. The term for generating plans of action can be for immediate, short term, medium term and long term periods.If management does not implement a plan the only plan that he can guarantee is a poor performance. Organising – In order to make sure that the plan is a success management have to make sure things within the company and the plan are properly organised. This is where management can divide, coordinate and control the task and information within the organisation. Assigning work and granting authority are 2 important elements of organising. Staffing – Now that the structure is properly put together, management needs to have employee's to carry out the plan. This is also known as human resource management.In this concept management will be devoted to properly acquiring, training, appraising, and compensating their employee's. Employees are what give a company a competitive edge. Management must ensure that the right number of and kind of employees are placed at the right places and at the right time when the organisation is in need of them. Directing – This is the ability to get employee's to achieve the goals of the company in the most effective and optimal way. Leading, motivating, communication and coordination are the elements that come under directing.Directing is about guiding and leading the people in an organisation. Controlling – This is the process that ensures whether the resources are obtained and used efficiently in achieving the organisational objectives. This function will be the last task that management will do. This will allow the ability to check the performance of the employee's to make sure it correlates with the input (plan) and output (performance). For this reason, that is why controlling function of management is closely linked with the planning function. ) It is the requirement of a team leader to achieve objectives set by management for a team. However, since the team leader cannot meet these objectives on their own, it will be required for the team leader to lead or manage a team to achieve success using the skills of the team. The team’s objectives will be those of the team leader. The team will consist of a number of individuals each working to achieve their own objectives, based on each individual’s particular skills, knowledge and expertise. This breaking down into specific tasks will contribute to the overall achievement of the objectives of the team.With this in mind a team leader must know their staff, but it is equally important that the staff know the team leader. A leader must know how to build and nurture such a team. A good leader knows when to be a leader and when to be a follower. Good leaders are good followers when that's what is needed. Other skills that the team leader will need to possess are: Integrity. Having strong internal guiding principles that one does not compromise. It means treating others as you would wish to be treated. Integrity promotes trust, and not much is accomplished without trust.Leading by example. Innovation and vision. Welcoming new tasks and new ways of doing things. Having a clear idea where his or her organisation and/or unit are going in the long term. Communication. Leaders need to learn to be proficient in both the communication that informs and seeks out information and the communication that connects interpersonally with others. Being able to listen well, explain things clearly, ask questions and be aware of what people really think and feel (not what they may say). Relationships.A leader who likes dealing with people issues, who can initiate and deepen relationships with others, has a great leadership ad vantage. This is a leader who can build a team and achieve impressive results. This can help with the ability to motivate others. Getting people to do things because they want to and not because they are told to. Persuasion. The ability to influence others and cause them to move in a particular direction is a highly important skill in leadership. A leaders ability to be persuasive is directly related to how much people trust you and how good your communication and relationships are.Adaptability. Adaptability and flexibility in not being bound by a plan are important success factors. A leader must move easily from one set of circumstances (the plan) to the next (the plan is not going as expected) and take them all in stride, even when the circumstances are unexpected. A good leader has to embrace change and see it as opportunity. Coaching and self-development. Developing others is an important role for a leader. Encouraging others to expand their capabilities and take on additional a ssignments is part of a leader’s responsibility.Leaders who feel threatened by the capabilities of others are generally challenged in this area. This coincides with being interested in what people think and feel. Self-development and expanding one’s own capabilities inspires trust and respect from the team which also goes hand in hand in developing others. Decision-making. A leader must be able to wade through information, comprehend what’s relevant, make a well-considered decision, and take action based on that decision. Making decisions too quickly or too slowly will impede leadership effectiveness. Planning.Planning involves making certain assumptions about the future and taking actions in the present to positively influence that future. Planning means to focus more strategically. Although important for guidance and focus, plans are rarely rigid. d) My job as a Senior Support Worker is to provide support to the Registered Manager and lead a small team of supp ort staff in the day to day running of the unit in line with the company’s objectives.

If you look closely at matters involving leadership, there are always three elements or variables: * the leader – qualities of personality and character * the situation – partly constant, partly varying the group – the followers: their needs and values. There are three areas of overlapping need which are centrally important which are related to task, group maintenance and the individual. Task – The reason a group of people come together to perform a task is because the task is too big for one person. A range of knowledge and skills are required and these will not be found in one person. Group maintenance – Many of the fo rmal or informal rules and procedures of the group are designed to promote unity and to maintain cohesiveness at all costs.There is a feeling that good relationships are essential towards a shared goal. This need to create and promote group cohesiveness is called group maintenance. Individual – Individuals bring into groups their own needs, for eg, recognition; a sense of fulfilment, status, and what Adair terms as the deeper needs to give to and receive from other people in a working situation. Adair believes that these individual needs are more profound than we sometimes realise. These needs may attract us or repel us from any given group.The three areas of need overlap and influence one another. If the common task is achieved, then that tends to build the team and to satisfy personal human needs in the individual. If there is a lack of cohesiveness in the team circle, a failure of team maintenance, then clearly performance in the task area will be impaired and the satisfac tion of individual members reduced. In order to achieve the common task and to maintain teamwork, certain functions have to be performed. Adair's three circles model emphasises the importance of distinguishing the individual from the group.It is fundamental that each of the circles must always be seen in relation to the other two. A leader must always be aware of what is happening in relation to the team in terms of the three circles. In 1993 Charles Handy pointed out that it is unlikely that there will ever be a situation where there is a perfect match between the need of the individual, the group and the task. The leader's job is to be aware of the tension and to manage it. A leader must maintain some distance, as they are responsible and accountable for: * Achievement of the common task Ensuring the group work as a team * Facilitating the development of the individuals Leaders need to interact with others whose support they need in order to accomplish goals. To gain their support , leaders must be able to understand and motivate them. To understand and motivate people, leaders must know human nature. Human nature is the common qualities of all human beings. People behave according to certain principles of human nature. Human needs are an important part of human nature and leaders must understand these needs because they can be powerful motivators.In 1970 Maslow felt that human needs were arranged in a hierarchical order and that the basic needs must be met before the higher order needs in the form of 5 levels: 5. Self-actualization — knows exactly who you are, where you are going, and what you want to accomplish. A state of well-being. 4. Esteem — feeling of moving up in world, recognition, few doubts about self. 3. Belongingness and love — belong to a group, close friends to confide with. 2. Safety — feels free from immediate danger. 1. Physiological — food, water, shelter, sex.Maslow deemed that people want and are foreve r striving to meet various goals. Because the lower level needs are more immediate and urgent, then they come into play as the source and direction of a person's goal if they are not satisfied. A need higher in the hierarchy will become a motive of behaviour as long as the needs below it have been satisfied. Unsatisfied lower needs will dominate unsatisfied higher needs and must be satisfied before the person can climb up the hierarchy. Leaders knowing where a person is located on the pyramid will aid in determining effective motivators.Almost no one stays in one particular hierarchy for an extended period. We constantly strive to move up, while at the same time various forces outside our control try to push us down. The goal as a leader is to help people obtain the skills and knowledge that will push them up the hierarchy on a more permanent basis. People who have their basic needs met become much better workers as they are able to concentrate on fulfilling the visions put forth to them, rather than consistently struggling to make ends meet.

Crime Causation and Diversion Paper

Crime Causation and Diversion Paper University of Phoenix Online Juvenile Justice Systems and Processes CJA/473 LeDetra Jones October 01, 2012 Crime Causation and Diversion Paper Today the public became more concern about youth crime rising within the community. The public also believes that some of juvenile delinquents do not belong behind bars whereas others do. In the concern of the juveniles who do not belong behind bars the public started creating community outreach programs, intervention, and prevention programs.These programs create an environment for the youth to understand the consequences of their actions, responsibility, and help. This paper will be examining two juvenile diversions, interventions, and prevention programs, which are Island Girl Power and Inafa' Maolek. The following will be addressed in the paper: How do they work to reduce juvenile crime (Based on analysis). Programs major goals, objectives, and core beliefs? Who are the key participants? Services provide d?Which program is most effective at reducing crime and why? How programs reduce juvenile crime and major goal, objectives, and core beliefs The Inafa'Maolek is Guam's only organization that dedicates exclusively to peacemaking, especially in settling disputes such as mediation, restorative justice, and conflict resolution training of all ages (Inafa'Maolek, 2010). The trainings conducted by Inafa'Maolek helps establish peer mediation programs in more than 30 public schools ranging from elementary to high schools.These special programs currently in schools include Date Rape Workshops, Bullying Workshops, and Hate Crimes Workshops. The organization provides programs to all sectors in the community, including senior citizens (Manamko) as well as DYA families. The heart and souls of its work focuses on mediating conflicts, many referred by Superior Court Judges (Inafa'Maolek). Island Girl Power is a program on Guam that works to Empower, Encourage, and Inspire young ladies to make posi tive lifestyle choices. This program believes that if the island works together to empower, ncourage, and inspire the young ladies of Guam to make a positive lifestyle choice by promoting positive male and female role models it helps to prevent the abuse and neglect in the families for generations to come (Blaz, 2009). Island Girl Power is a local program, taken, and expanded from a national program Girl Power. Its prevention program focuses on offering young ladies a variety of classes, activities in hopes of expanding their goals. It is a safe place where people can volunteer at their leisure and is expanding into the community through volunteers and center willing to offer classes (Blas, 2009).This program is a clubhouse more like and located in Dededo, GU. Their hours of operations are from Monday through Friday 8a. m. -5p. m. , and Saturdays 9a. m. -3p. m. This clubhouse offers many activities such as dancing, self-defense, and big sister club, etc. The reason this club focuses on young ladies is that it helps them to gain self pride, become wiser, and make smarter choices in life. Young ladies are usually self conscious about themselves and rebellious than males. They are more vulnerable to the outside world once they step into it.While the two organizations/clubs works in many ways of preventing and interventions juvenile delinquency, here are the clubs/organizations major goals, objectives, and core beliefs of what it can provide for the community as well as juveniles. The mission statement for the Inafa'Maolek is a conflict resolution organization dedicated to reducing violence related litigations and foster peace and harmony in schools, Workplaces, and communities (Inafa'Maolek, 2009). The vision statement for the Inafa'Maolek is that it will enhance peacemaking and reduce violence related litigation through advocacy, mediation, and education (Inafa'Maolek, 2009).The mission statement for the Island Girl power is that we want the girls to know just h ow special they are here at Island Girl Power! We believe that each girl can create a positive change in her life. If every girl makes it her goal to do her best, how can go wrong? We want to give girls ages seven to 14 a safe and enjoyable place to learn and play (Blas, 2010). By making the girls wiser to the world around them girls will make smarter choices in life- and maybe even help a friend. By accepting all girls, regardless of the income or status, we help bridge the gap between the haves and the have-nots (Blas, 2010).When a girl joins a club it means so much to them, the acceptance, and the pride they feel when they are part of a group is irreplaceable. We as an organization help girls understand the importance of community service by showing them the example of the wonderful people who volunteer to create a place just for them (Blas, 2010). The clubhouse goal is to decrease the incidence of teenage pregnancy, suicide, sexual, and substance abuse. These problems are the mo st serious challenges facing our girls today. We know that we cannot change the island overnight, but we can make it better -One girl at a time! Blas, 2010). The two organizations help juvenile delinquents/youths in the community to improve themselves to make wiser decisions and to give a sense of direction to where they should be in the future. Knowing that the organizations/clubs are do their best to provide the community with the proper services to help the children to become better helps the people to get over that there are other outlets for their teens. With major goals, objectives, and core beliefs here are the key participants of the programs and the services the programs provide.The key participants of these programs and services provided The key participants of these programs are teens in intervention, juvenile delinquents, teens in prevention (joining so they do not commit the crime), and teen volunteers. These key participants help the organizations to better understand teens nowadays. Juvenile delinquents in the early days probably have committed more serious crimes than teens today. There was not enough services provided to the teen besides, juvenile correction facilities. The community is very limited on the help needed for their children, and some are forced to look elsewhere that type of help.Because the key participants are teens whether trouble or just interested in the program, there are services that the programs for them. The services that Inafa'Maolek provides are one, peace theater- where teens perform a situation and how to bring instead of conflict. Second, mediation- where two parties meet privately to work out a solution. Third, restorative justice- RJ sessions provide a context within which people can take responsibility for their actions, restitution are made to victims, offenders are reintegrated, and harmony are restored to a community. Fourth, conflict coaching (Inafa'Maolek, 2009).These are the main services that this program provides, other services include; volunteering in schools, socializing with other teens, restore the community, and helping others who need help. The services that Island Girl Power provides are encouraging girls on their personalities, social skills, looks, and abilities to please other rather than develop their own interests and aspirations. Island style dance classes so that they can learn about who they are and where they come from. Self-defense classes so that young ladies have that skill to protect themselves or another against harm.Occasional classes in Gef Pago as well as the big sister service where an older girl will help guide the younger ones. Of the services provided by the two programs the most effective program to reduce juvenile crime would be Inafa'Maolek. Most effective program The reason for this decision is the Inafa'Maolek provides services and outcomes used to for schools and became very popular to teens, the government, other programs. It also provides more se rvices than other treatment programs or organizations on the island. There are no other program that provides these services than Inafa'Maolek.It has shown that when teens take these sessions it guides them into becoming better person not only them but for his or her families. Conclusion In conclusion, as the community starts to see more troubled teens/delinquents these organizations/programs are ready to fight these behaviors to make them a better person. These programs were created to help the children because they are the future leaders and so forth. By understanding what drives them to commit these crimes is a mystery and why these programs try to bring all teens and their families to help one another.

Free Essays on Chess and Computers

Chess is a very versatile game that can be related to or compared with many other things. Such as philosophy, war, film, etc. But the topic that I have chosen to research on is â€Å"chess and computers†. Since the birth of the technology i.e. Computer, chess players are being compared to artificial intelligence. Researchers are trying to find out who can play better chess. Humans or Artificial Intelligence. At present computers can only use the intelligence that is load in it. But it can have many more moves than human chess player can think. Such as computer chess program â€Å"Deep Blue†, which has beaten few chess grand masters. However, when computer plays chess, it does not think about the move it makes but performs a series of calculations to make the right move. This all based on the positions of the pieces on the board. Human chess players use their skills, judgment and previous experiences to decide about the moves they are going to make. Many chess computers can play at high levels due to fast calculations, but at this speed the computer has an advantage over human chess player because human brain cannot perform calculations at the speed a computer can. Despite this all, a human chess player can also have the advantage of thought and the abilities, which he had gained from his previous experience. If a human chess player made some unusual chess moves, which computer cannot predict because all computer intelligence is based on algorithms and any unusual move can throw computer off guard and that gives the human chess player advantage over the computer in the chess game. So the question here is, â€Å"Is the artificial intelligence is at level of human intelligence or not?† According to Boden, â€Å"The human brain is the most complex part of the human body if not the most complex subject known to human kind.

Chemical Composition of Table Salt

Chemical Composition of Table Salt Table salt is one of the most common household chemicals. Table salt is 97 percent to 99 percent  sodium chloride, NaCl.  Pure sodium chloride is an ionic crystal solid. However, other compounds are present in table salt, depending on its source or additives that may be included before packaging.  In its pure form, sodium chloride is white. Table salt may be white or may have a faint purple or blue tinge from impurities. Sea salt may be dull brown or gray. Unpurified rock salt may occur in any color, depending on its chemistry. Where Does Salt Come From? One of the main sources of table salt is the mineral halite or rock salt. Halite is mined. The minerals in mined salt give it a chemical composition and flavor unique to its origin. Rock salt commonly is purified, since halite occurs with other minerals, including some that are considered toxic. Native rock salt is sold for human consumption, but the chemical composition is not constant and there may be health risks from some of the impurities, which can be up to 15 percent of the mass of the product. Another common source of table salt is evaporated sea water. Sea salt consists mainly of sodium chloride, with trace amounts of magnesium and calcium chlorides and sulfates, algae, sediments, and bacteria. These substances impart a complex flavor to sea salt. Depending on its source, sea salt may contain pollutants found associated with the water source. Also, additives may be mixed in with sea salt, mainly to make it flow more freely. Whether the salt source is halite or the sea, the products contain comparable amounts of sodium, by weight. In other words, one cannot be used in place of the other to lower dietary sodium. Additives to Salt Natural salt already contains a variety of chemicals. When it is processed into table salt, it may also contain additives. One of the most common additives is  iodine in the form of potassium iodide, sodium iodide, or sodium iodate. Iodized salt may contain dextrose (a sugar) to stabilize the iodine. Iodine deficiency is considered the biggest preventable cause of mental retardation. Salt is iodized to help prevent cretinism in children as well as hypothyroidism and goiter in adults. In some countries, iodine is routinely added to salt (iodized salt) and products that do not contain this additive may be labeled uniodized salt, Uniodized salt has not had any chemicals removed from it; rather, this means supplemental iodine has not been added. Another common additive to table salt is sodium fluoride. Fluoride is added to help prevent tooth decay. This additive is more common in countries that dont fluoridate water. Doubly-fortified salt contains iron salts and iodide. Ferrous fumarate is the usual source of iron, which is added to help prevent iron-deficiency  anemia. Another additive may be folic acid (vitamin B9). Folic acid or folicin is added to help prevent neural tube defects and anemia in developing infants. This type of salt may be used by pregnant women to help prevent common birth defects. Folicin-enriched salt has a yellowish color from the vitamin. Anti-caking agents may be added to salt to prevent the grains from sticking together. Any of the following chemicals are common: Calcium aluminosilicateCalcium carbonateCalcium silicateFatty acid salts (acid salts)Magnesium carbonateMagnesium oxideSilicon dioxideSodium aluminosilicateSodium ferrocyanide or yellow prussiate of sodaTricalcium phosphate
