Undergrad (Sonicator) - Research Paper Example The production of methanol was done through the distillation of wood. Methanol today is industrially synthesized from a nonstoichiometric mixture of carbon monoxide, hydrogen and carbon dioxide over Cu/ZnO/AL203 catalysts. Methanol is an industrial chemical used as raw material in the manufacture of solvents such as formaldehyde and producing acids, for example, acetic acid through hydroformylation. Synthesis of methanol is crucial due to wide usage of methanol in industries. Sonicator (Ultrasonic) is one method used to manufacture methanol (Eta, Valerie, 71). Ultrasonic is a phenomenon used in reactive chemical whereby ultrasound energy of approximate 20 kHz is used to agitate the reactants. This method is efficient because necessary temperature and energy are generated by ultrasonic machine. Methanol is a short chain alcohol that is immiscible. The use of the sonicator or ultrasonic is to synthesize methanol in a reaction entitled as transesterification. Catalytic functional group in methanol is methoxide (CH3O-) which is formed when methanol reacts with a strong base or when metals like potassium react with anhydrous methanol (Arutyunov, Vladimir, 95). Mechanism of ultrasonic effect on esterification was illustrated experimentally using bubble- dynamic model where ultrasound energy and micro bubbles in the reactor increased the interface formed between the triglyceride and methanol emulsion, thus considered a physical reaction and not a chemical reaction (Eta, Valerie, 103). There seems to be the best use of the sonicator and why it is mainly used for the production of methanol. The use of Sonification is good as it has led to the production of more methanol and carbon while using less energy. The use of Sonification makes it possible for synthesis of methanol via the use of carbon dioxide and hydrogen, which leads to the water-gas shift formation and surface morphology effects. However, because the use of carbon dioxide and hydrogen is a two-way step,

Potential conflicts Essay Example for Free

Potential conflicts Essay Every State has three inherent powers which are all necessary and indispensable for its continued existence. These powers may exist even without an express constitutional grant. Among these powers are Police Power, Power of Eminent Domain, and the Power of Taxation On the other hand, citizens in a democracy enjoy certain rights and freedom. These rights serve as safeguard for the protection of the people against excessive and unnecessary exercise of these three powers mentioned. The beauty of a democracy lies in the proper balance between the civil rights and liberties of the people and the fundamental powers of the State. An over-concentration of power in the government will lead to dictatorship or authoritarianism. An over emphasis in freedom and liberty will result to anarchy and mob rule. Analysis of the USA Patriot Act Consider the enactment of the USA Patriot Act as our country’s response to international terrorism. Pres. Bush upon signing the Patriot Act into law emphasized that this law will provide law enforcement officials with sufficient weapons and tools to fight terrorism. â€Å"Remarks by President Bush at Signing of USA Patriot Act of 2001†) He emphasized that we need this law for the protection of our country and for our protection as well. Despite the highly publicized importance of the Patriot Act to protecting our national security and territory, civil rights advocates however fear that the said law may have severe repercussions to our individual liberties. This law which should protect us from terrorists may even be used against us. Some of the provisions of the said law will give the law enforcement authorities unlimited power to search our physical property and seize them, monitor our electronic communication and bank accounts, library records and even our medical records. Last January 2006, The Association of American Physicians and Surgeons and the American Civil Liberties Union joined together in calling for the amendment of Section 501 of the Patriot Act which gives sufficient authority for government officials to seize any â€Å"tangible things† (Jeanne Lenzer)  Under Section 501, â€Å"(a)(1) The Director of the Federal Bureau of Investigation or a designee of the Director†¦may make an application for an order requiring the production of any tangible things (including books, records, papers, documents, and other items) for an investigation to protect against international terrorism or clandestine intelligence activities, provided that such investigation of a United States person is not con ducted solely upon the basis of activities protected by the first amendment to the Constitution. † (Sec 501) It is because of this reason that in a number of medical center’s privacy policy there is already a statement informing their patients that they are authorized to disclose any medical information about the patient to authorized federal officials. Personal information about our health conditions, our sickness, the doctor treating us, the medicines we are taking and any other personal information, which we consider as confidential may now be discovered by the government, placed in a database together with all other personal information taken from other people, and this information could be transferred from one government agency to another. Conclusion I am a Libertarian. I do not think we need to sacrifice our liberty for the purpose of protecting ourselves from terrorism. Our civil liberty, such as our right to privacy, is our treasured rights. For some that is all they have. If the government will take this away from them they will be worse than the terrorists. There is only one solution to this problem and that is for the public to call for the amendment of this provision so that section 501 may finally be deleted from the Patriot Act. Although the said provision may also be useful for any criminal investigation, I believe however, that no government official should be given unbridled discretion to seize our medical records. As a rule, seizure of medical records should not be allowed subject to certain exceptions such as if a suit has been filed against the person whose medical record is being seized or if the person is a suspected terrorist who has confirmed affiliations with terrorists organizations.

KFC Leadership Style | Analysis

KFC Leadership Style | Analysis Employees never work along in the organizations, there must be some kind of teamwork involve in the working process, both formal and informal. Leadership acts as an important factor that strongly influences employees performance, motivation and attitude. It has been argued that differences between success and failure, whether in business, war or football, leadership is largely attributable to success. 1.1 Definition Of Literature Review A literature review is defined as target to show important facts regarding approaches on a topic in the methodological method. It also means they are not primary sources because it is not original or new work. 1.2 Definition Of Leadership Leadership is become very much on every managers mind today in organizations. Originations are struggling due to the increasingly dynamic environment. As the challenges of leading and managing increase, leaders of organizations need to understand process, skills and knowledge to perform leader functions effectively. 1.3 Definition Of Motivation Motivation is the willingness to exert high levels of effort to reach organizational goals, conditioned by the efforts ability to satisfy some individual need (Belasen Frank, 2008). Motivating employees are one of the continual challenges of managerial behaviour, that are also managers fundamental reasons for engaging in various activities and work. 1.4 Introduction Of KFC Kentucky Fried Chicken (KFC), as we all know is one of the popular fast food outlets worldwide with the theme Its finger lickin good. The first KFC outlet in Malaysia was opened on 1st January 1973 at Jalan Tunku Abdul Rahman, Kuala Lumpur. Today there are more than 390 KFC outlets nationwide and are still counting. Great tasting chicken has become synonymous with KFC and has been enjoyed by Malaysians ever since. The KFC we will be talking about is in Nilai, Negeri Sembilan. 2.0 Literature Review 2.1 Defining Leadership Leadership can be defined as the process whereby one individual influence other group members towards attaining defined group or organizational goals (Orlando, 2008). More important, successful organizations need effective leadership, who are capable of increasing an organizations employee motivation; in turn improve the overall performance and organizational productivity (Richard, 2007). In addition, Drucker in his The Leader of the Future sums up leadership as The only definition of a leader is someone who has followers. It is said that many of the worlds best leaders do not have the integrity as well as certain values which wont be discussed in the modern days. In my opinion, leadership is different from management. Managers have subordinates which are below them while leaders have people who follow them. Managers will normally utilize their position of power in order to do things. In the process of work, managers orders his or her employees while they will follow because of the reward given which is the minimum of their salary. Looking at the other way round, leaders gives up their authoritarian control, due to their followers which follows them in a voluntary way. 2.2 Leadership Theories Terry (2000) has highlighted that leadership is an influence relationship between leaders and followers who intend real changes and outcomes that reflect their shared purposes. Block (2002) has noted that as a process, leadership is, ideally the use of non-coercive influence to shape the groups or organizations goals, motivate behavior towards the achievement of those goals and help define group or organizational culture. Effective Leadership Russell, (2000) defined effective leader as those leaders who are able to improve organization productivities, in turn develop distinctive competitive advantages for organizations. In other words, effective leaders usually have an inspiring vision; they will try to form a group of people to work as a team, making them into a powerful team which utilizes as a competitive advantage. Effective leaders know how to make people function according to what they are good at, and how to motivate them to excel their performance. Leaders need to understand the balance technique in any individual team members quest with the objective of creating synergy. Leaders need his or her members in their team to forego the goal for the individual best coherent with the effort of the whole team. 2.3 Leadership Style Autocratic vs. Democratic vs. Laissez-faire leadership style Taggart (1989) defined that, broad classification of leadership style consists of authoritarian (or autocratic) style, democratic style and laissez-faire (genuine) style. The definition of autocratic style is: It is where the focus of power is with the manager, and all interactions within the group move towards the manager. The manager alone exercises decision-making and authority for determining policy, procedures for achieving goals. Work tasks and relationships, control of rewards or punishments. Kotter (1990) expressed Democratic leadership style takes wishes and suggestions of employees into consideration. It is more a human relations approach, in which all members of the group are seen as equal, and they are all important contributors to the final decision. Laissez-faire leadership style involves limited control or influence of leaders over his or her group members. A member is given a goal and mostly left alone to decide how to achieve it. The leaders function as one of the group member, and he only provide direction and suggestions when necessary. Task Orientation and People Oriented Leader Behavior Another way of looking at different leadership styles is in terms of dimension of leader behavior. As early as 1950s, a large body of research at University of Michigan and Ohio State University suggested that leaders differ greatly along the dimensions; at the high end of two dimensions is task orientation versus people orientation. Task Orientation leader behavior is more concern about the production and primarily focus on getting the job done. Whereas the People Orientation leader behavior reflects how much a leader is concerned for the people around him, providing support and encouragement for them. There is no hundred percent right or wrong in using which leader behavior, it depends on the situation and organizations nature business. 2.4 Situational Factors Path-goal Theory Different organization has different business environment, we must take the situational factors into the consideration to analyze and evaluate the effectiveness of the leadership. Bartram Casimir (2007) cited in Houses path-goal theory argued that the primary function of a leaders job is to coach and guide workers to choose the best path for reaching their goals, in the mean time to make valued rewards available in the work place. In short, the leader should clearly know the paths to achieve goals. As showed in the path-goal framework, the path-goal theory contends that employees tend to listen to leaders who are play an helping role in their works, in other words, effective leaders clarifying what employees need to do to get to where they should be, and they help the employees to do so. Moreover, Stone Russell (2004) argued that the theory suggests job satisfaction, motivation, and actual performance are enhanced. In addition, path-goal theory also states four types of leadership behaviors to help their employees accomplishing tasks. (1) Directive leadership, which is an approach focused on providing specific guide and on planning work rules and schedules. (2) The supportive leadership mainly focuses on build good relations with employees and fulfills their needs and wants. (3) The participative leadership, whereby the leader allow employees to get involved in the decision making process. (4) The achievement oriented leadership is talking about the company leader who sets challenges and expects employees improve performances. Furthermore, the environmental characteristics include three factors like task structure, authority system and work group. Directive leadership style does not match with high task structure. It is not necessarily for leaders to repeatedly tell employees the requirement of some routine works. The authority system is another important characteristic that will affect the leadership styles. The higher degree of formality the less effective of employees performances will show. Source: House, R.J. Mitchell, T.R. 1994, Path-goal theory of leadership, Journal of Contemporary Business, vol. 3, pp. 21-36. 3.0 Conclusion and Recommendation In sum, developing an effective leadership in organizations is the most essential, yet the most difficult tasks for organization management. Great leadership is the combinations of individual traits, leading skills and of course the situational contexts. As we have discussed above, effective leadership is require both intrapersonal and interpersonal skills. The intrapersonal skills are of paramount important, as it is logical and obvious that success or great leader all start from within. Only with personal inside strong desire to excel, passion, enthusiasm, determination, commitment, faith and effective personal values can a person become a true leader for others. A great leader among the people always starts as a great leader of his own. Then, interpersonal skills come into place, where the ability and skills to network, communicate and interact with the other people come into place. The effective leaders can guide companies through many different channels. Because of this, it is i mportant to know which leadership qualities motivate employees the best. Throughout the analysis and evaluation, there have been many leadership style theories identified. As we have found that, the autocratic leadership style has gone out of fashion in recent years, though certain situations, such as emergencies situations. Therefore, effective leaders must adjust the leadership style to various situations. In that sense, there is no one leadership style is appropriate for every occasion or situation. The most effective style to use depends upon the situation and whether the group members are willing and able to take on the responsibility. To be effective as a leader, its important to know your group in terms of knowledge, ability, desire and willingness, and be ready to adapt your style to suit the dynamic environment. An important task in the coming years will be the training and testing of future leaders. Further more, organizations have to have a bigger picture of long term success, that is strengthening leadership competencies will improve organizational effectiveness. When subordinates trusted their leaders leadership, and they deem it is equitable for them to obtain satisfactory rewards and outcomes when they made the greatest efforts. Therefore, effective leadership leads to a positive motivation and motivated employees will satisfy the customers of the organizations. In a long-term, it will help organization creating or maintaining a sustainable organizational competitive advantage. References Svensson, G Wood, G. (2007).

Do Creationism and Intelligent Design Have a Place in the Classroom? Es

Surveys show that fifty percent of adults in Turkey, forty percent in the USA and fifteen percent in the UK reject the theory of evolution and believe that life on Earth came into existence as described in the religious texts (Jones and Reiss, 2007; Miller; Scott and Okamoto, 2006; Lawes, 2009). President G. W. Bush commented as follow: Both sides ought to be taught properly...so people can understand what the debate is about....Part of education is to expose people to different schools of thoughts....You’re asking me whether or not people ought to be exposed to different ideas, and the answer is yes (Baker and Slevin, 2005). However other views have been reported in the literature. Pennock (2007: 72) summarizes his position as follows: What should be educators’ and citizens’ response when IDC’s lobby in Kansas and elsewhere to ‘teach the controversy’? We should respond with a slogan of our own: Teach only real science in science classes, not creationist pseudoscience. Jackson in his essay â€Å"The Personal and the Professional in the Teaching of Evolution† shares similar opinions (2007). In 2006, The Times published an article by Halpin reporting the inclusion of creationism in a new biology syllabus produced by the OCR exam board. James Williams, science course leader at Sussex University's School of Education, told the Times Educational Supplement: "This opens a legitimate gate for the inclusion of creationism or intelligent design in science classes as if they were legitimate theories on a par with evolution fact and theory.† The OCR exam board argued that the aim of the syllabus was to make students aware of scientific controversy in accordance to the QCA guidelines (QCA, 2007: 37): Students should be taught how scientif... ...theory and the notion of an old Earth/universe are supported by a mass and evidence and fully accepted by the scientific community (DCSF, 2007). It seems unreasonable to say that creationist explanations and beliefs lie outside the science classroom and will not be addressed without any further discussion (Anderson, 2007; Smith, Siegel and McInerney, 1995). Addressing the validity of evolution or issues about creationism and intelligent design in science lessons could be valuable when illustrating the aspects of how science works such as how scientific knowledge and scientific ideas evolve and how the scientific community invalidates those changes. The role of effective teaching is surely to help students learn about the theory of evolution and appreciate the ways of science, its limitations and how scientific knowledge might differ from other forms of knowledge.

Performance and Safety of Hydraulic Turbines

Research Paper M.V. Sai Ram AP17110020010 Branch: ECEHYDRAULIC TURBINES:Abstract: The first part of the paper contains the choice of small turbines for run of the river power plants. Then a discussion is given on the optimization of the performance of different types of large turbines. Finally a discussion on the safety and necessary maintenance of turbines is given with special attention to bolt connections.A set of empirical equations has been developed which defines the peak efficiency and shape of the efficiency curve for hydraulic turbines as a function commissioning date for the unit, rated head, rated flow, runner speed, and runner throat or impulse turbine jet diameter. The aim of this investigation was to develop an environmentally friendly nano -hydraulic turbine utilizing waterfalls. A model of an impulse type hydraulic turbine constructed and tested with an indoor type waterfall to arrive at an optimum installation condition. Effects of an installation parameter, namely distance between the rotor and the waterfall on the power performance were studied. The flow field around the rotor was examined visually to clarify influences of installation conditions on the flow field. The flow visualization showed differences of flow pattern around the rotor by the change of flow rate and rotational speed of the rotor.Every single turbine is custom-designed specifically to meet the requirements of a hydroelectric power plant. Performance of a designed turbine is validated, to some extent, by computational fluid dynamics simulations. Field performance testing of hydraulic turbines is undertaken to define the head-power-discharge relationship that identifies the peak operating point of the turbine. This relationship is essential for the efficient operation of a hydraulic turbine. The art of hydraulic turbine design never stands still but always progresses. In recent years major emphasis has been on the materials of construction and on such features of design as will reduce maintenance work and costly outages in the field.LimitationsHydro power plant or we can say that hydraulic turbines are widely used from the last decades.

Multi User Operating Systems Essay

An operating system is a set of software programs, which manage computer hardware in a controlled fashion. The operating system controls the file-system, process management, memory management and peripherals. Multi-user operating systems are used on large mainframe computers. A mainframe computer system has one very powerful processing unit, which may contain many microprocessors. Many users will all share this processing unit. They use terminals (a keyboard and a monitor) to access the mainframe computer. A multi-user operating system lets more that one user work on a mainframe computer at the same time. Features of a MUOS The main features of multi user operating systems are resource sharing, multi tasking and background processing.  · Using resource sharing in a multi-user operating system allocates the CPU time of the mainframe computer between the different users. Each user in turn is given a small time slice of the CPU time. Because these time slices are very small the users believe that they are all using the mainframe at the same time. Resource sharing also lets users share peripherals such as printers or hard drives and also lets users share files on a network.  · Multi-tasking lets the operating system run more than one program at a time. One example of a multi tasking could be editing a word document while browsing the Internet. The way this is done is by the processor using time slicing.  · Background processing is a term which means when commands are not processed straight away but rather executed â€Å"in the background†, often while other programs are interfacing with the system in real time. Types of MUOS There are three main types of multi user operating system. These are distributed systems, time sliced systems and multi processor systems.  · In a distributed system, to the user it appears to be a single computer system but in fact is made up from a number of different host computers, which are connected together. This is completely hidden from the user. All decisions about what computer each user will connect to would be taken by the distributed system’s operating system. Each individual host within such a distributed could be any type of computer at all.  · Time sliced systems split each users time of use of the system to fairly allocate each user a fair amount of time of use. These time slices are so small that it appears to the user that their programs are running continuously when in fact the CPU is jumping from user to user. Each time slice is milliseconds long so each user is actually given several time slices every second. The more each user tries to do the slower their programs will run as their time slice has to split between their different tasks.  · Multi processor systems use more than one processor in a single computer to make themselves much more powerful and relieve the load of sharing the operating system and CPU. Users will again be distributed time slices but since there will be more than one processor there will be more allocation of time to each user rather than if there were only one processor. Main Components of a MUOS There are many components that are needed to run a multi user operating system. These include the processor, memory, data storage devices, terminals and input/output devices.  · The processor, also known as CPU or central processing unit In  terms of computing power, the CPU is the most important element of a computer system. The CPU is the brains of the computer. Sometimes referred to simply as the processor or central processor, the CPU is where most calculations take place. On large machines, CPUs require one or more printed circuit boards. On personal computers and small workstations, the CPU is housed in a single chip called a microprocessor.  · Memory refers to the physical memory that is internal to the computer. Sometimes mistaken for mass storage devices such as hard drives the word ‘main’ is used to differentiate it from this. Memory is usual known as RAM or Random Access Memory. The computer can only manipulate data that is in main memory, therefore, every program that you execute and every file that you access must be copied from a storage device such as a hard drive into main memory. The amount of main memory on a computer is crucial because it determines how many programs can be run at one time and how much data can be readily available to a program.  · There is a couple of data storage devices used in multi user operating systems. The term usually refers to mass storage devices such as hard disk drives or tape drives. Large amounts of data such as the operating system itself and any other programs that are installed on the computer are all kept on such devices so that can be accessed by the RAM and then processed to be used by the user. The main types of storage are: – o Hard disk drives: The most common type of mass data storage used on a computer because of the large amounts of data which can be held and the speed it can be accessed at. o Floppy disks: Much slower than hard drives and hold very little data but are easy portable and inexpensive. o Optical disks: This method uses lasers to read and write data. Optical drives hold a large capacity but are not as fast as hard drives but are as portable as floppy disks and with the right equipment (CD Writer) can be used to read and write data. o Tapes: Not too expensive and hold large amounts of data but do not permit random access of data.  · There are two main types of terminal used to access multi user operating systems. One is a dumb terminal, which just consists of a computer and a keyboard, but practically no processing power. They allow a user to carry out work on the remote server, minicomputer or mainframe. Smart terminals provide additional resources to perform local editing and simple processing. Basically, smart terminals are low cost PC platforms with no external storage like hard drives booting from a network.  · Input/Output devices refers to devices with allow the user to put data and receive data to and from the computer system. For instance an input device may be a keyboard or a mouse and output devices can be things such as monitors and printers. Software Components of a MUOS The main software components of a multi user operating system are the kernel, device handlers, spoolers and the user interface.  · The kernel of an operating system is the most protected and privileged layer of the operating system and acts as a timekeeper and regulator for the system, controlling any time slicing for multi user or multi tasking functions. This ensures fairness in the way resources are allocated and used, and dealing with interrupts having different priorities, which arrive to signal internal and external events.  · A device handler is a small program, which controls a particular type of device connected to a computer. There are device drivers for every hardware component on a computer. If a complex device is added to the machine then a device handler must be added to the operating software because this will contain the code needed to communicate with the device.  · A spooler puts jobs on a queue and takes them off one at a time. Most operating systems come with one or more spoolers, such as a print spooler for spooling documents. In addition, some applications include spoolers. Many word processors, for example, include their own print spooler. A good print spooler should allow you to change the order of documents in the queue and to cancel specific print jobs. Acronym for simultaneous peripheral operations on-line, spooling refers to putting jobs in a buffer, a special area in memory or on a disk where a device can access them when it is ready. Spooling is useful because devices access data at different rates. The buffer provides a waiting station where data can rest while the slower device catches up.  · The user interface is the junction between a user and a computer program. An interface is a set of commands or menus through which a user communicates with a program. A command-driven interface is one in which you enter commands. A menu-driven interface is one in which you select command choices from various menus displayed on the screen. The user interface is one of the most important parts of any program because it determines how easily you can make the program do what you want.

Frankenstein - Dr.Frankenstein was the real monster essays We have all heard or seen the story of Frankenstein one time or another, whether it be the recent horror movie version Mary Shelleys Frankenstein or the classic comedy version of Young Frankenstein.
