We present and describe the fairy shrimp Streptocephalus sahyadriensis sp. nov. from the Western Ghats of India. This species is most similar to S. simplex Gurney, 1906 and S. dichotomus Baird, 1860 sharing similar basic antennal appendage morphology. However, S. sahyadriensis sp. nov. differs in the form of the ornamentation on the peduncle and the arrangement and form of spines on the antennal appendage. The three species also have different egg surface morphologies. The Asian species of Streptocephalus are discussed and a key to species is provided. Copyright © 2014 Magnolia Press.

Quantum radiation properties of nonstationary Kerr–de Sitter (KdS) black hole is investigated using the method of generalized tortoise coordinate transformation. The locations of horizons and the temperature of the thermal radiation as well as the maximum energy of the nonthermal radiation are derived. It is found that the surface gravity and the Hawking temperature depend on both time and different angles. An extra coupling effect is obtained in the thermal radiation spectrum of Maxwell’s electromagnetic field equations which is absent in the thermal radiation spectrum of scalar particles. Further, the chemical potential derived from the thermal radiation spectrum of scalar particle has been found to be equal to the highest energy of the negative energy state of the scalar particle in the nonthermal radiation for KdS black hole. It is also shown that the generalized tortoise coordinate transformation produces a constant term in the expression of the surface gravity and Hawking temperature. © 2016 World Scientific Publishing Company

The study is described in which the ethanol and methanol extracts from Acacia nilotica L. bark were evaluated for their possible antibacterial and antioxidant activity. Preliminary phytochemical analysis of ethanolic and methanolic extracts was carried out by using simple chemical tests. Total phenolic content of both the extracts was determined by Folin-Lowry method. Ethanolic extract of Acacia nilotica L. was found to contain 307.54 ± 2.67 mg GAE/gm dry weight of phenolics and 496.42 ± 6.89 mg QE/gm dry weight of flavonoids. Antioxidant activity of both the extracts was evaluated by phosphomolybdenum method and DPPH radical scavenging method. Ethanolic extract demonstrated the highest DPPH radical scavenging activity of 71.8 ± 0.18 % at 1000μg/ml concentration. Both the extracts showed broad spectrum antibacterial activity. The study suggests that the plant has promising applications in the development of phytomedicines with antibacterial and antioxidant properties.

Megymenum distanti, a new species of the dinidorid subfamily Megymeninae, is described from India and is compared with M. affine and M. brevicorne. It is the sixth species of this genus known from India. Remarks on the habitat, where the type material was collected, photographs of the host plant and a brief description of all instars are provided. This species is of a different color as an adult and as nymphs, a situation which is unusual. Copyright © 2012 Magnolia Press.

An updated inventory of large branchiopods of the Western Maharashtra state, India is presented for the first time. Employing current identification keys, we have detailed the egg morphology of Eulimnadia indocylindrova, which shares some similarities with E. geayi from South America and E. alluaudi from Madagascar, based on these egg characters. A thorough re-description of few morphological traits of the same species is also presented. We also have described the female of a Cyzicus species seen rarely from the studied region. Distributional comments on few species are also reported. Copyright © 2015 Magnolia Press.
