E-Procurement Implementation: Critical Analysis of Success Factors' Impact on Project Outcome

Abstract: The 21st century has seen migration of many governance functions and services to Internet. The terms like e-Governance and m-Governance are no more unfamiliar words but are political reality. The adoption of e-procurement by government entities to optimise and economise public procurements has been the buzzword of transparent governance. In fact e-procurement has been touted as panacea for corruption and bureaucratic red-tapism. Literature is replete with studies which underline numerous benefits of migration of procurement functions to Internet. However, e-Government procurement has not taken off in India through it is an Integrated Mission Mode Project as a part of National e-Governance Project (NeGP) launched by Govt of India in 2006. A recent review of the e-procurement implementation by DIT, Ministry of Communication & IT brought out that the progress e-procurement project implementation has been dismal. In this backdrop, we undertook study of contemporary research literature to identify Critical Success Factors for e-procurement project implementation. The research methodology followed included analysis based on an elaborate study of e-procurement literature, pertinent government orders and multinational/ international agreements to identify Critical Success Factors. The study concludes that existing literature indicates flat nature of CSF i.e. there is no relation with the stage of e-GP implementation vs significance of a CSF. Therefore, existing CSFs and their study models do not aid managerial decision making by project managers. Finally, the paper brings out research gaps and suggests direction for future research for making e-GP a success in India.

How severe acute respiratory syndrome coronavirus-2 aerosol propagates through the age-specific upper airways.

Abstract: The recent outbreak of the COVID-19 causes significant respirational health problems, including high mortality rates worldwide. The deadly corona virus-containing aerosol enters the atmospheric air through sneezing, exhalation, or talking, assembling with the particulate matter, and subsequently transferring to the respiratory system. This recent outbreak illustrates that the severe acute respiratory syndrome (SARS) coronavirus-2 is deadlier for aged people than for other age groups. It is evident that the airway diameter reduces with age, and an accurate understanding of SARS aerosol transport through different elderly people's airways could potentially help the overall respiratory health assessment, which is currently lacking in the literature. This first-ever study investigates SARS COVID-2 aerosol transport in age-specific airway systems. A highly asymmetric age-specific airway model and fluent solver (ANSYS 19.2) are used for the investigation. The computational fluid dynamics measurement predicts higher SARS COVID-2 aerosol concentration in the airway wall for older adults than for younger people. The numerical study reports that the smaller SARS coronavirus-2 aerosol deposition rate in the right lung is higher than that in the left lung, and the opposite scenario occurs for the larger SARS coronavirus-2 aerosol rate. The numerical results show a fluctuating trend of pressure at different generations of the age-specific model. The findings of this study would improve the knowledge of SARS coronavirus-2 aerosol transportation to the upper airways which would thus ameliorate the targeted aerosol drug delivery system.

Identification of trees and their trunks from mobile laser scanning data of roadway scenes

Abstract: Trees along the roads are important assets, which need continuous assessment and maintenance. The mobile laser scanning (MLS) has been adopted as mainstream mapping technique for three-dimensional ...

Dynamics and mechanism of the Crystal II → smecticG phase transition in TB7A by a temperature‐dependent micro‐Raman study and DFT calculations

Abstract: The solid to smecticG (SmG) phase transition in a Schiff base liquid crystalline compound, terepthal-bis-heptylaniline (TB7A), is monitored in situ by temperature-dependent Raman microspectroscopy, using the band of a CH in-plane bending mode as a marker. Contrary to the earlier report of a sudden wavenumber shift, the in situ measurement shows very clearly that a new Raman band at ∼1160 cm−1 appears at the Crystal II SmG transition. The dynamics of this phase transition is discussed in terms of a triple well potential below 210 K and a double well potential above 210 K. The phase transition essentially takes place as a result of intra-molecular rotation about the long molecular axis. The optimization energy at various fixed dihedral angles, (CCCN) are calculated using density functional theory (DFT) at the B3LYP/6-31G* level of theory. The relative energy at each dihedral angle is calculated relative to optimization energy obtained without any constraints and plotted as a function of dihedral angle (Φ) between the adjacent phenyl ring planes, which also shows a double well potential at room temperature.
