One equation turbulence model account for the history effects such as turbulent energy, diffusion and convection.

One equation turbulence model account for the history effects such as turbulent energy, diffusion and convection. Correct Answer False

One equation turbulence model only solves one turbulent transport equation mostly the kinetic energy. It is the two equation turbulent model that accounts for the history effects such as turbulent energy, diffusion and convection.

In a survey conducted over a group of people, it was found that 65% of them have a Facebook account, 40% of them have an Instagram account and 25% of them have a Twitter account. It was also concluded that 20% have an account on both Facebook and Instagram, 12% have an account on both Instagram and Twitter and 14% have an account on both Facebook and Twitter. If 8% of the people had an account on all the three websites, what percentage of the people do not have an account on any of the three websites?
S1: Mr. Ford, it is commonly reported, once declared that history was "bunk".
P: Yet the American, generally speaking, is by no means ignorant of history or uninfluenced by his knowledge of it.
Q: This remarkable utterance of his, if indeed he made it, was in itself an outcome of history.
R: The Americans know more about our history than we know about theirs, though I hope that will soon be remedied.
S: Such contempt for all things past, and such engaging frankness in expressing it were themselves the outcome of the social history of the United States in the 19th century.
S6: And the American's conception of his own country as the representative of freedom and of democracy is the product of history as popularly taught and conceived over there.

The Weberian model of bureaucracy has been criticised from a variety of stand points.
Consider the following points in this regard:
1. The Weberian model appears to be a 'machine theory' and a closed system model taking little account of organisational interactions with the environment.
2. The structural features of bureaucracy as laid down by Weber might be suitable for routine and repetitive tasks but these would produce dysfunctional consequences in terms of human behaviour if the jobs would involve innovation and creativity.
3. Weberian model has not been found to respond adequately to the tasks of socioeconomic transformation in the developing countries. These tasks require quick changes whereas the capacity of the Weberian model for adaptation to change is rather slow.
4. Weber's model is confined to the study of formal bureaucratic structure and fails to take notice of the informal structure of bureauracy such as informal relations, informal norms and values, an informal power hierarchy and informal power struggles.
Which of the above points make a valid criticism of the Weberian model? Select the correct answer from below:
User level threads are threads that are visible to the programmer and are unknown to the kernel. The operating system kernel supports and manages kernel level threads. Three different types of models relate user and kernel level threads. Which of the following statements is/are true ? (a) (i) The Many - to - one model maps many user threads to one kernel thread (ii) The one - to - one model maps one user thread to one kernel thread (iii) The many - to - many model maps many user threads to smaller or equal kernel threads (b) (i) Many - to - one model maps many kernel threads to one user thread (ii) One - to - one model maps one kernel thread to one user thread (iii) Many - to- many model maps many kernel threads to smaller or equal user threads
Consider the following statements regarding the importance of diffusion and choose the correct answer:
1. The exchange of gases takes place by the principle of dependent diffusion
2. The process of diffusion is involved in transpiration of water vapours
3. The ions are absorbed by the simple diffusion during passive salt uptake
4. Diffusion is an effective means of transport of substances over a very short distance and helps in the translocation of food materials

The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. S1: History is a subject that is so little valued today that it is almost impossible to win world fame as a historian, yet that is exactly what Toynbee was able to. S6: Among the civilizations that he studied was that of India. P: We usually think of history as a chronological account of the development of various states and empires under the ruler. Q: Toynbee’s view of history was different. R: He tries to find the pattern behind the birth, growth and decay of civilization. S: Though he used the recorded history of mankind, he was interested not merely in the chronology of single states or group but in the rise and fall of whole civilizations. The correct sequence should be

Modern civilization is completely dependent on energy, which has therefore to be abundant and also economical. About 85% of the world's energy is supplied by oil, coal and natural gas while nuclear, hydro, wind and solar power and biomass supply the rest. Coal, nuclear and hydro are used primarily to generate electricity while natural gas is widely used for heating. Biomass is used both for heating and cooking. The wind and solar power is the future's hope as they are sustainable energy sources. Oil powers almost all machines that move and that makes oil uniquely versatile. Oil powered airplanes carry 500 people across the widest oceans at nearly the speed of sound. Oil powered machines produce and transport food. Oil powered machines are ubiquitous. Clearly, we live in the age of oil but it is drawing to a close. According to data available if oil production remains constant until it's gone, there is enough to last 42 years. Oil wells will produce less as they become depleted, which will make it impossible to keep production constant. Similarly natural gas and coal will last another 61 years and 133 years respectively. Naturally, as they become scarce, they become expensive, leading to a worldwide energy crisis. If we are to survive on this planet, we have to make a transition to sustainable energy sources. The transition may be willy-nilly or planned - the choice is ours. The dawning era of limited and expensive energy will be very difficult for everyone on earth but will be even more difficult if it is not anticipated. It is of utmost importance that the public and policymakers understand the global energy crisis and act in tandem to ensure that the species 'homo sapiens' does not become extinct.
