Management of business process reengineering projects: a case study

Business process reengineering (BPR) projects are undertaken by outward-looking companies that are looking for significant change in their performance and wanting radical changes in the chosen parameters. Generally, these companies are trendsetters in their respective industries. BPR projects take longer time for completion and may require significant capital inflows as well. This paper discusses BPR, special requirements/considerations for BPR project management and, through a case analysis, seeks to identify and emphasise the critical success factors for the implementation of a BPR projec

Constructing a database of alien plants in the Himalaya to test patterns structuring diversity

Differences in the number of alien plant species in different locations may reflect climatic and other controls that similarly affect native species and/or propagule pressure accompanied with delayed spread from the point of introduction. We set out to examine these alternatives for Himalayan plants, in a phylogenetic framework. We build a database of alien plant distributions for the Himalaya. Focusing on the well-documented regions of Jammu & Kashmir (west) and Bhutan (east) we compare alien and native species for (1) richness patterns, (2) degree of phylogenetic clustering, (3) the extent to which species-poor regions are subsets of species-rich regions and (4) continental and climatic affinities/source. We document 1470 alien species (at least 600 naturalised), which comprise ~14% of the vascular plants known from the Himalaya. Alien plant species with tropical affinities decline in richness with elevation and species at high elevations form a subset of those at lower elevations, supporting location of introduction as an important driver of alien plant richness patterns. Separately, elevations which are especially rich in native plant species are also rich in alien plant species, suggesting an important role for climate (high productivity) in determining both native and alien richness. We find no support for the proposition that variance in human disturbance or numbers of native species correlate with alien distributions. Results imply an ongoing expansion of alien species from low elevation sources, some of which are highly invasive

Unified Angular Momentum of Dyons

Unified quaternionic angular momentum for the fields of dyons and gravito-dyons has been developed and the commutation relations for dynamical variables are obtained in compact and consistent manner. Demonstrating the quaternion forms of unified fields of dyons (electromagnetic fields) and gravito-dyons (gravito-Heavisidian fields of linear gravity), corresponding quantum equations are reformulated in compact, simpler and manifestly covariant way

LANDSLIDE HAZARD ZONATION IN AND AROUND KEDARNATH REGION AND ITS VALIDATION BASED ON REAL TIME KEDARNATH DISASTER USING GEOSPATIAL TECHNIQUES

Landslides are one of the frequently happening disasters in this hilly state of Uttarakhand which accounts to the loss of lives and property every year especially during the rainy season which lead to affect the families. With the development of satellite observation technique, advanced data analysis tool and new modeling techniques landslide hazard zonation map can be prepared.In the present study, Landslide Hazard Zonation (LHZ) for Kedarnath to Augustmuni region of Rudraprayag district of Uttarakhand state was carried out using Remote Sensing and GIS technique. For the preparation of LHZ map, year 2010 high resolution satellite data have been used. After preprocessing of the data various thematic layers are prepared in GIS environment. The weighted-rating system technique were used for the LHZ map showing the five zones, namely “very low hazard”, “low hazard”, “moderate hazard”, “high hazard” and “very high hazard” . This map has been validated after the tragedy of Kedarnath in Uttarakhand, Total no. of 224 Landslides has been marked from Kedarnath to Augustmuni region just after the kedarnath tragedy in year 2013. When this landslides thematic layer is overlaid on LHZ, the study shows that approximately 50% landslides was there where in LHZ map high and very high hazard zones have been identified. After the tragedy our team workers have gone to the field, with the help of DGPS around 40 ground control points have been taken to validate our result. So by using this geospatial technique around 50% people’s life can be saved.</p

Ethnopharmacology of Some Important Medicinal Plants of Nanda Devi National Park (NDNP) Uttarakhand, India

Abstract: Ethnopharmacology deals with the applied aspects of plants and has been emerged as an important discipline of traditional botany with modern sciences. With the increasing demands of vegetational resources in developing world, it has been attracted much attention in recent past. The paper presents few of the important medicinal plants present in alpine and sub alpine regions of core and buffer zone of Nanda Devi National Park (NDNP), district Chamoli, Uttarakhand. Since inhabitants and tribal communities have strong faith and belief in Indigenous Health Care system, they have been interviewed along with herbal practitioners, priests and shepherds during the entire study. Establishing small scale industry on medicinal plants may be helpful in capacity building of unprivileged inhabitants of this remote region. [Nature and Science 2010;8(11):9-14]. (ISSN: 1545-0740). Key words: medicinal plants; folk recipes; NDNP, U.K. Introduction The Nanda Devi National Park is the first and foremost highly valued core of the Nanda Devi Biosphere Reserve. It has an area of 624.6 sq. km. and has an average altitude exceeding 4500 m asl surrounded by high mountain ridges and peaks on all sides. Some of the important peaks encircling the National Park are Dunagiri (7066 m), Rishi Pahar (6992 m), Mangraon (6765 m), Nanda Khat (6631 m), Maiktoli (6803 m), Mrigthuni (6655 m), Trishul I-II (7120-6319m), Nanda Devi (7817 m), Devisthan I-II (6529 -6678 m) and Hanuman Peaks (6070 m), situated in the park. The park is situated in the form of a cup, with lush-green meadows, cluttering white water falls, and rich wild flora and fauna Ethno-medicinal plants, as a group, comprise approximately 8000 species and account for about 50% of all the higher flowering plant species in India. A large number of the country&apos;s rural population depends on medicinal plants for treating various illnesse

Quaternion Gravi-Electromagnetism

Defining the generalized charge, potential, current and generalized fields as complex quantities where real and imaginary parts represent gravitation and electromagnetism respectively, corresponding field equation, equation of motion and other quantum equations are derived in manifestly covariant manner. It has been shown that the field equations are invariant under Lorentz as well as duality transformations. It has been shown that the quaternionic formulation presented here remains invariant under quaternion transformations.Comment: Key Words: Quaternion, dyons, gravito-dyons, gravi-electromagnetism.

Generalized Gravi-Electromagnetism

A self consistant and manifestly covariant theory for the dynamics of four charges (masses) (namely electric, magnetic, gravitational, Heavisidian) has been developed in simple, compact and consistent manner. Starting with an invariant Lagrangian density and its quaternionic representation, we have obtained the consistent field equation for the dynamics of four charges. It has been shown that the present reformulation reproduces the dynamics of individual charges (masses) in the absence of other charge (masses) as well as the generalized theory of dyons (gravito - dyons) in the absence gravito - dyons (dyons). key words: dyons, gravito - dyons, quaternion PACS NO: 14.80H
