Black holes can be defined as the set of events from which it is not possible to escape to a large distance. To understand how a black hole might be formed, one first needs to have an understanding of the life cycle of a star. A star is formed when a large amount of gas, mostly hydrogen, starts to collapse in on itself due to its gravitational attraction. As it contracts, the atoms of the gas collide with each other more and more frequently, and at greater and greater speeds.Full Text

The riverbank erosion mechanism is very complex, and sediment particles on the riverbank are subjected to a number of forces. Among those forces, the force of cohesion between the particles plays a very significant role. Also important is the viscous force coming into play due to the presence of water-bridge between each pair of particles. Frequency of bank failure is proportional to the erosion rate and bank failure causes flood. Every particle is surrounded by a family of similar particles, and all are bound together under this force of cohesion. In this paper, a recently published analytical model named the ''Truncated Pyramid Model'' for the arrangement of particles has been used, and the general equations for the impending acceleration, as well as the escape velocity, of a particle have been modified to accommodate the viscous force. The effect of the forces on a soil particle is presented graphically for pure water. The graphs depict the deviation from results of the previously published research work due to the consideration of the viscous force. The escape velocity of a particle is the key to determining the other parameters related to riverbank erosion, such as the entrainment rate and the volumetric rate of bank erosion.Keywords

This paper focuses on business environment aspects and strategic choices and their interrelation that have a bearing on the operation of enterprise owners in an industrial cluster. Environmental issues are reflected in the labour, machinery and other input condition, access to finance, competition from substitute products, marketability based on easy transport etc. While strategic choices focus on the direction that a firm nurtures in mind and through which the goals are expected to be achieved. This study is based on primary survey covering sixty bell metal enterprises in the Nadia district of West Bengal in India. Likert scaling has been used for capturing the environmental and strategic perception of the entrepreneurs. Factor analysis based on principal axis factoring with varimax rotation has been used to analyse the impact of multiple perceived environmental and strategic variables. Further canonical correlation analysis has been used to find the degree of correlation between the set of business environmental variables and that of strategic components. The study helps isolate major variables that have a bearing on perceived environmental and strategic components. The analysis suggests that choice of strategic variables by enterprise owners is usually in coherence with the environmental aspects affecting the business.Keywords

This paper seeks to analyse the impact of relational capital components on the performance of clay tiles clustered firms in Murlu, Saltora region of Bankura district, in the state of West Bengal in India. It is based on an assemblage of relational capital for assessing and determining the importance of relationships in the perspective of firm performance level. The study considered eight relational capital indicators for eliciting firm responses to the level of relational capital. A survey was conducted on 60 firms in the cluster. Cronbach’s alpha has been used to test the reliability of a series of individual components of relational capital. Principal component method was applied to derive the relational capital index based on all the indicator components. It is found to be strongly related to profitability performance. Overall, regression of the profitability figures carried out on individual relational capital components has yielded a significant outcome and some of the components are also found to have a significant impact on firm performance level. Based on the analysis, concrete suggestion is provided for spotting areas of relational capital, which, if handled and cultivated proficiently and deftly, can play a significant role in influencing firm performance level.Keywords
