  • Random amplified polymorphic DNA (RAPD-PCR) analysis of 56 animals of four different genetic groups of dwarf cattle in Kerala was done as a single step analysis. Bandsharing (BS) values were calculated for animals of each group and between groups as an analytical tool to find out genetic variation among animals. The different factors affecting BS values were estimated using Harvey''s Least squares analysis. The effects of genetic group, Guanine-cytosine (GC) content of primer and gel on BS values were found significant. Bandsharing values of Kasargode-Highrange dwarf animals were significantly different from Vechur, Vatakara and their combinations. The Vechur, Vatakara and Vechur-Vatakara combinations were found to be more uniform (high BS value) compared with other combinations. The bandsharing value was lowest with primers of GC content 90% and highest with 80% GC content. The effect of gel on BS value points to the need of adjustments of gel factor for calculation of BS values.

  • Calamus andamanicus Kurz is one of the commercially important solitary rattans endemic to Andaman and Nicobar islands. The habitat suitability modeling program, MaxEnt, was used to predict the potential ecological niches of this species, based on bioclimatic variables. The study revealed high potential distribution of C. andamanicus across both Andaman and Nicobar islands. Of the 33 spatially unique points, 21 points were recorded from South and North Andamans and 12 from Great Nicobar Islands. The islands like Little Andaman, North Sentinel, Little Nicobar, Tllangchong, Teressa were also predicted positive even though this rattan is not recorded from these islands. Mean diurnal range, higher precipitation in the wettest month of the year, annual precipitation and precipitation in the driest month are the main predictors of this species distribution.

  • Kerala, a southern-west state of India, has been vigorously studied due to its unique development status. Indeed, Kerala shows such a high level of social development as Human Development Index indicates, yet it is suffering from the low level of economic. As a result, scholars have examined a broad range of rationales to understand the 'Kerala Development Model' as discussing historical contexts, social welfare policies, land reforms by Communist Party of India, and so on. Among them, scholars agree that education is one of the most critical factors that led to social development of Kerala. Despite the consensus, there has been lack of research that deeply look into how education has been delivered, what impacts it has on people, and why it contributes to social development in Kerala. This research, thus, would discuss the meanings, values and impacts of education with the capability approach that is originally termed by Amartya Sen. The approach criticize the dominant paradigm of 'development' that is materialistic oriented, instead it emphasizes expanding a range of capabilities of people to reach 'development' that people can act upon what they value and cherish. Based on Sen's perspective, we believe that dimensions of education can be re-defined and expanded in a relation to development.

  • Very recently, Mubeen, et al. [6] have obtained fifteen contiguous function relations for k-hypergeometric functions with one parameter by the same technique developed by Gauss. The aim of this paper is to obtain seventy-two new and interesting contiguous function relations for k-hypergeometric functions with two parameters. Obviously, for $k{\rightarrow}1$ we recover the results obtained by Cho, et al. [2] and Rakha, et al. [8].

  • Caloglossa species occurs in freshwater streams around Southest Asia. We report it from 2 different riverine sites in Kerala, India. Tetrasporangiate plants were observed in field collections from the Periyar River and Chalakkudy River. The Chalakkudy isolate did not reproduce in culture but the Periyar isolate developed abundant tetrasporangial sori in culture. Many spores were discharged and most were abortive, but some germinated normally, sporelings forming male gametophytes with numerous spermatangial sori and females with many procarps, viable carposporophytes and some nonfunctional (no carpospores) pseudocystocarps. Some carpospores germinated forming new tetrasporophytes. Molecular evidence (28S rDNA and rbcL) placed the Indian specimens close to C. beccarii and C. fluviatilis. Considering the freshwater habitat and morphology of vegetative thalli (blade shape, rhizoid arrangement, and number of rhizoid filament per cell), the Indian specimens should be assigned to C. beccarii.

  • The objective of this paper is to present 87 recurrence relations for the Jacobi polynomials $P_n^{({\alpha},{\beta})}(x)$. The results presented here most of which are presumably new are obtained with the help of Gauss's fifteen contiguous function relations and some other identities recently recorded in the literature.

  • We consider an extended version of a logarithmic series distribution and discuss the estimation of its parameters by the method of moments and the method of maximum likelihood. Test procedures are suggested to test the significance of the additional parameter of this distribution and all procedures are illustrated with the help of real life data sets. In addition, a simulation study is conducted to assess the performance of the estimators.
