Wide spread penetration of IT has become a part of our social, business and economic fabric. Today, information is at present as equal or more important as roti, kapra aur Makan (bread, cloth and house). Therefore, value of information using new technology serve better to organization as well users than before. Literature survey of ERP models practically implemented & used at present by various...

Spectropolarimetry of intact plant leaves allows to probe the molecular architecture of vegetation photosynthesis in a non-invasive and non-destructive way and, as such, can offer a wealth of physiological information. In addition to the molecular signals due to the photosynthetic machinery, the cell structure and its arrangement within a leaf can create and modify polarization signals. Using M...

Switchable and tunable chiral metamaterial response is numerically demonstrated here in different uniaxial chiral metamaterial structures operating in the THz regime. The structures are based on the bi-layer conductor design and the tunable/switchable response is achieved by replacing parts of the metallic components of the structures by photoconducting Si, which can be transformed from an insu...

In this paper, the author will discuss two popular terms, i.e. organized civil society and global governance and their relations. The paper is mainly about organized civil society (international non-governmental organizations) and democracy in global governance. First, the author will provide a few related definitions. These terms, although are highly contested, need to be identified to avoid c...

This paper focuses on the role of information management models and information and communication technology (ICT) applications in facilitating implementation of social responsibility and sustainable practices in contemporary organizations. On the one hand, the fields of corporate social responsibility and sustainability have grown exponentially in the last decade. Both include three dimensions...

The circular hydraulic jump exhibits behavior quite different from that commonly observed in planar jumps. Here we examine experimentally some of the causes and consequences of those differences. We suggest that surface tension plays a dominant role in establishing the shape of the circular jump for impinging jets. The importance of surface tension is a direct result of the thinness of the liqu...

Metallo-dielectric electromagnetic bandgap (EBG) structures are studied in the millimeter regime with a finite difference time domain (FDTD) simulator. Several EBG waveguiding structures are considered for millimeter-wave power splitting, switching and filtering operations. It is demonstrated that triangular EBG structures lend themselves naturally to the design of Y-power splitters. Square EBG...

There are competing conceptions of democracy. In particular, the terms “democracy” and “democratic” have been defined by political philosophers and political scientists in many different ways. Which one is right? How should one choose among the proposed definitions? A democracy is perhaps always a State, but the adjective “democratic” is often applied to other entities as well; for example, org...

We design an ultra-thin multi-band polarization-insensitive metamaterial absorber (MMA) using a single circular sector resonator (CSR) structure in the microwave region. Simulated results show that the proposed MMA has three distinctive absorption peaks at 3.35 GHz, 8.65 GHz, and 12.44 GHz, with absorbance of 98.8%, 99.7%, and 98.3%, respectively, which agree well with an experiment. Simulated ...
