The study deals with the Scientometric study on the publication of "Geochemistry". The records are collected from Web of Science Databases for the period of 1989-2020. A total of 2603 papers were identified in Web of Science database. The study reveals that, most of the researchers preferred to publish their research results in journal and more numbers of articles were published in the year 2019. The authorship trend shows that, out of total 2603 literature published, 92.5% of the publication published under the joint author. Four thousand three hundred and eighty nine authors have contributed the total of 2603 articles. Further this study also identified to analyses coverage growth rates, relative growth rate, doubling time, most prolific authors, Degree of collaboration, Areas of research concentration, Price's Square Root Law and Pareto Principle and citation analysis is also noted [ABSTRACT FROM AUTHOR]

The Study examines the Biodiversity in India as revealed in the database of web of science in the year of 1991-2017. It was seen that the analysis included author productivity, authorship pattern, degrees of collaboration, year wise Cited references, Relative growth rate, and doubling time. This study also verified Lotka's Inverse square law of author productivity, Price's Square root law, Pareto Principle (80*20 Rule). [ABSTRACT FROM AUTHOR]

This study analyses the Indian Scientists contributions of research papers related to the topic in Data Mining was undertaken from Web of Science Databases has been used to retrieve the data for 22 years (1999-2020) by the searching the keyword "Data Mining". The study reveals that, most of the researchers preferred to publish their research results in journals; as such 88.59% of articles were published in journals. More numbers of articles were published in the year 2019. The authorship trend shows that, out of total 1096 literature published, 95.53 % of the publication published under the joint author. It is observed that author productivity is not in agreement with Lotka's law, but productivity distribution data partially fits the law when the value of Chi-square to 25212.62. Further this study also identified to analyses source wise. Degree of collaboration, Areas of research concentration, word frequency, Geographical distribution of the literature and citation analysis is also noted. [ABSTRACT FROM AUTHOR]

Total Factor Productivity (TFP) measures the growth in output which is not accounted for by inputs. Data Envelopment Analysis which forms the basis for the computation of Malmquist TFP index is used in this paper to study the performance of different river basins in Andhra Pradesh state, India. The results indicated that average technical efficiency of all the basins is only 66%. In all the basins there was a decline in growth of agricultural output during the first two decades, viz., 1979-1980 to 1988-1989 and it had picked in the last decade (1999-2000). All the river basins have TFP change greater than 1 indicating progress in agricultural productivity. Out of the 40 river basins, 14 river basins have technical efficiency change less than 1 indicating decline in TFP growth whereas all the basins have technical changes greater than 1 implying that there is shift in production frontier over years. In general, within the TFP, technical change contributed more than technical efficiency change. Looking at the future options for increasing the agricultural output in the river basins, it is important to focus on improving the TFP growth compared to increasing the quantities of physical inputs.

There has been a rapid increase in the number of firms undertaking business-to-business (B2B) electronic commerce (e-commerce) initiatives. Although there are various benefits to B2B e-commerce, there are also inhibitors to its deployment. This study empirically investigates the inhibitors for deploying Web-based B2B e-commerce applications in organizations. A field survey of senior IT executives was conducted to examine the key problems that inhibit the deployment of Web-based B2B e-commerce. A comprehensive list of inhibitors was derived from an extensive review of the literature and pretested with senior IT executives. Data from 249 firms were factor analyzed to yield the underlying structural dimensions of inhibitors impacting the deployment of Web-based B2B e-commerce. Univariate t-test and multivariate discriminant analysis were carried out on the resulting ten dimensions to compare B2B (i.e., firms who have deployed B2B) and non-B2B firms (i.e., firms who have not deployed B2B). The results suggest that key inhibitors in B2B deployment are the lack of top management support, unresolved technical issues, the lack of e-commerce strategy, and the difficulties in cost-benefit assessment of e-commerce investments. Implications of the results for researchers and IT/engineering management executives are discussed. [ABSTRACT FROM AUTHOR]

Statistical uniformity of discharge variation is an important parameter in designing drip irrigation laterals. A simple analytical equation is derived to determine the coefficient of variation of discharge. This equation is used to determine the coefficient of variation of discharge for a numerical problem. The result is compared with the energy gradient line approach. Both the methods give the same result. For any required coefficient of variation of discharge, the diameter of a lateral can be designed directly for a known lateral length, slope, emitter discharge exponent, pressure head at the start of the lateral, and discharge rate through the lateral, by writing the analytical equation in quadratic form.
