One does not have to walk long in the hallways of schools to see that something is very wrong. We search in our students for the passion and enthusiasm for learning that they possessed before entering school. Instead, we find idle bystanders content to remain distant from formal instruction and from their hearts. Too often they remain dazed, passive consumers window shopping the mall of educati...

The current study presents the results of the aerodynamic noise prediction of the flow field around a NACA 0012 airfoil at a chord-based Reynolds number of 100,000 and at 8.4 degree angle of attack. An incompressible Large Eddy Simulation (LES) turbulence model is applied to obtain the instantaneous turbulent flow field. The noise prediction is performed by the Ffowcs Williams and Hawkings (FW-...

the present article focuses on the evaluation of a first-moment closure model applicable to film cooling flow and heat transfer computations. the present first-moment closure model consists of a higher level of turbulent heat flux modeling in which two additional transport equations for temperature variance kθ and its dissipation rate εθ are considered. it not only employs a time scale that is ...

BACKGROUND Because beliefs about the soul after death affect the dying experience, patients and survivors may want to discuss those beliefs with their healthcare provider; however, almost no medical research describes such beliefs, leaving healthcare professionals ill prepared to respond. This exploratory study begins the descriptive process. METHODS Assuming that culture is key, we asked old...

in the evolution of muslim’s philosophical thought, it was sadr al-motaallehin who overcame many of complexities in philosophical studies on the soul and presented a new outlook. it is clear that mulla sadra’s philosophical psychology has been depended upon his special principals. the present research, therefore, is to explain the effect of sadra’s theory of substantial movement, as one of his ...

in the fourth verse of the chapter tariq, human soul has been known to have a guard. commentators, however, have presented different views knowing human soul and its guard respectively as: 1- human spirit and divine angles, 2- all creatures and god, 3- animal power and human spirit. as one of the fundamental causes for disagreement lies in the philosophical tendencies of the commentators, this ...

BACKGROUND Although diverse definitions have been construed for burnout syndrome, most authors consider it to be a single phenomenon, the result of chronic work-related stress. However, in order to enable specific intervention strategies to be adopted, it is first necessary to establish different profiles for the syndrome. In this respect, have been proposed three burnout types ("frenetic", "un...

the design and optimization of hydrocyclones using cfd techniques are gaining popularity and the key to a successful simulation lies with the accurate description of the high turbulent swirling behavior of the flow. this paper presents a detailed comparison between the omega rsm and the rng k–e turbulence model, which are both derived specially for modeling swirling or rotational flow, in the s...

The energy equation for turbulent flow of fiber suspensions was derived in terms of second order correlation tensors. Fiber motion of turbulent energy including the correlation between pressure fluctuations and velocity fluctuations was discussed at two points of flow field, at which the correlation tensors were the functions of space coordinates, distance between two points, and time.
