The paper attempts to scrutinize the results retrieved from Web of Science in this topic under Open Access category. Bibliometric techniques has been made to analyse the characteristics of the research output in Green Propulsion and the required data were downloaded from Web of Science from 2000 to 2014 (15 years). This study investigates the growth pattern, year-wise, institution-wise, country-wise distribution of articles. The authorship pattern and Degree of collaboration has been calculated. The prolific authors along with the H-index and the obtained citations have been tabulated. The fitness of Lotka’s law has been tested.

Annual reports of the University of Kerala from 1980 to 1999 (20 years) have been taken as a source to collect the publication data of faculty members working in the science departments of the University of Kerala. A total number of 1542 articles were produced during the period under study. The study shows that the mean year taken to bring out one article by a lecturer is 0.915, reader is 0.906 and professor is 0.471. Female members need more time than male members to publish journal articles.

Thomson Reuters Web of Knowledge is a premier research platform, helping to find, analyze, and share information in the sciences, social sciences, arts, and humanities. The data for the present analysis has been retrieved for a period of 14 years during 1999 to 2012 from this database. This study aims to analyse the Indian contribution in the subject area. The study also analyses year-wise, language-wise, document type-wise distribution and also the country-wise analysis which provides the percentage of Indian share to this subject. The analysis also includes institution-wise categorization; Degree of Collaboration and also verifies the fitness of Bradford's Law of Scattering.

It is published by American Institute of Aeronautics and Astronautics. This paper presents bibliometric analysis of the journal during 2006-2010 which includes 780 papers and 15648 references. The analysis covers various parameters like growth pattern, authorship patterns, and distributions with regard to subject, year, institution and geographical area. The citing pattern of authors is also analysed from the reference provided for each article. It is also analysed to know the most productive year. Length-wise analysis of articles is also carried out. The study also reveals the degree of collaboration among the authors and Lotka‟s law is also applied to find the author productivity. The major finding of the study is that universities are the most productive sector and that the most productive country is USA.

Publication productivity is expressed by the number of papers published by a selected unit in a given time. In Kerala, although higher education and research have much wider importance and the publication productivity is also increasing, no systematic attempt has been made to analyze the pattern of this literature productivity. In this context, it is relevant to examine the productivity patterns of the faculty members of the universities. Materials and Methods: This study is based on the data collected from the publications of teachers pertaining to physics department of the three universities of Kerala that is,

Authorship pattern, Degree of Collaboration, the appropriateness of Lotka’s Inverse Square Law and year-wise and designation-wise distributions have been studied. The year-wise distribution of publications indicates that there is a growth in the number of publications. It is found that multi-authorship dominates among university teachers and there is no statistically significant difference between the experience and productivity. Designation-wise Degree of Collaboration shows that Professors are having a high Degree of Collaboration which indicates that increase in the age and experience results in more collaborative papers. The Lotka’s inverse square law seems to be rejected for the present data set

University of Kerala is one of the premier higher education institutes which cater the educational needs of the Kerala. The present study evaluates the research productivity of University of Kerala based on the data collected from Web of Science over a period of thirteen years from 2000 to 2012. This study attempts to analyse the overall performance of the faculty members of Science Departments of University of Kerala in research productivity. The parameters such as form-wise, year-wise, subject-wise classification of published papers, most productive authors and the most preferred journals, etc. are considered for the study. The impact factor and the citation received were also analysed. The study reveals that Chemistry is the subject which produces more number of papers while the multi-authorship also possesses a lead role in this subject. Indian journals are the most preferred journals to publish the articles which are followed by UK. Collaborative Coefficient varies from subject to subject. The result shows that the research productivity of the University of Kerala is much recognised at international level.
