Kenmotsu Manifolds

In the present article, we have investigated pointwise pseudo-slant submanifolds of Kenmotsu manifolds and have sought conditions under which these submanifolds are warped products. To this end first, it is shown that these submanifolds can not be expressed as non-trivial doubly warped product submanifolds. However, as there exist non-trivial (single) warped product submanifolds of a Kenmotsu manifold, we have worked out characterizations in terms of a canonical structure T and the shape operator under which a pointwise pseudo slant submanifold of a Kenmotsu manifold reduces to a warped product submanifold.

AbstractIn this paper, we have investigated the homogeneous and anisotropic Bianchi type–I cosmological model with a time-varying Newtonian and cosmological constant. We have analytically solved Einstein’s field equations (EFEs) in the presence of a stiff-perfect fluid. We show that the analytical solution for the average scale factor for the generalized Friedman equation involves the hyper-geometric function. We have studied the physical and kinematical quantities of the model, and it is found that the universe becomes isotropic at late times.

The Difference

<p>In elementary chemistry courses students often demonstrate difficulty with real understanding of Resonance Theory i.e. canonical structure vs. real molecule difference, so unanswered puerile questions during lecture made the subject boring. Particularly students unable to understand the difference between a real microscopic moiety and it’s proposed sketch or model at early stages of their learning. In such situations use of suitable analogy other than the subject area make the teaching more effective. Using an analogy from the daily life act as a powerful tool to explain curious questions efficiently to develop the interest of the students in subject. Sharing of personal experiences and analogies among scientific community is an effective way to spread scientific knowledge magnificently.<br></p>

Activity Domain

The alignment of business and knowledge strategies necessarily includes the individual and the organizational perspectives. A major problem in this context is to reconcile these perspectives into a common framework for alignment. To this end, an intermediate level is introduced–the activity domain. The activity domain is a canonical structure comprising all kinds of organizational units, irrespective of size and organizational level. The organization is regarded as a constellation of activity domains, each having a capability to produce an outcome that the organization needs in order to fulfill its goals. Alignment is defined as the management of dependencies between capabilities such that these capabilities fit the business’s strategic intents. As a consequence, business and knowledge strategies can be linked to the same target–the activity domain. Practical guidelines and alignment targets for these strategies are suggested.
