Evaluation of certain new class of definite integrals

Abstract: Brychkov [Brychkov YuA Evaluation of some classes of definite and indefinite integrals Integral Transforms Spec Funct 2002;13:163–167] evaluated some interesting classes of definite and indefinite integrals involving various special functions and the logarithmic function Motivated essentially by Brychkov's work [Brychkov YuA Evaluation of some classes of definite and indefinite integrals Integral Transforms Spec Funct 2002;13:163–167], we aim at presenting several classes of definite integrals involving hypergeometric functions and the logarithmic functions, which are expressed explicitly in terms of Psi and generalized zeta functions Some interesting special cases of our main formulas are given Relevant connections of the results presented here with those earlier ones are also pointed out

DNA Barcoding: A Potential Tool for Invasive Species Identification

Abstract: Invasive alien species epitomize the group of nonindigenous species that invade a geographic area and impose detrimental effects environmentally, ecologically, and economically. The management of invasive species will be less complicated at the primary stage of invasion since their population will be represented by a few numbers of individuals. But the detection of these few individuals will be a strenuous task if they are cryptic and exhibit low detectability. Molecular diagnostic tools bestow favorable support for the precise and brisk detection of morphologically indefinite alien species. The more recent outbreak of DNA barcoding lends inspiration for the assessment of biodiversity in a more accurate and also in an inexpensive manner. This typical procedure stands out as a reliable toolkit for the detection of individual/bulk samples, forensic residues, and environmental DNA and enhances rapid response management. Several DNA barcodes, including mitochondrial COI gene, rbcL, matK, trnH-psbA, and ITS (nuclear internal transcribed spacer), have been extensively used as a global bioidentification system for detecting the alien species that invade different ecosystems. This chapter discusses invasive species and the implication of DNA barcoding in their identification as well as management process.

Clupeid fish hosts a Peniculus sp. (Pennellidae, Siphonostomatoida, Copepoda)—First report on new host and season dependent prevalence

Abstract: Pennellid copepod Peniculus fistula fistula (Nordmann, 1832) (Synonym: Peniculus fistula Nordmann, 1832, Aphia ID: 745880), a worldwide distributed species, has been recovered from at least 19 teleost families. The present paper reports for the first time from the Malabar coast (South India), not only the existence of a new host family, Clupeidae, hosting this parasitic copepod species (P. fistula fistula) but also their season dependent hosting. A total of 123 marine fish species, belonging to 77 genera and 38 families surveyed along the Malabar coast, only the clupeid, Anadontostoma chacunda (Hamilton, 1822) was shown to be infected by this copepod species; all the recovered (copepod) parasites were invariably found attached at the mid portion of the caudal fin lobes and lying parallel to the host body, indicating the strict site-specific parasitisation. There is a discrete seasonality in the prevalence (P<0.05) as the sign of infection was noticed during the period from September to May with relatively high prevalence during winter months (November–January). During the monsoon months (June–August), the host fish was found completely free from Peniculus infection. Interestingly, all the 229 recovered specimens (P. fistula fistula) were gravid females having paired uniserrate egg sacs with the length more than its own body length.

Plays and counterplays: an intertextual analysis of communist and anti-communist plays in malayalam theatre

Abstract: The current study, which is the first part of a larger project, undertakes how Communism, a political ideology with international ramifications, was represented through political theatre in the context of South India, especially, Kerala. This enquiry will look into both communist and anti-communist manifestations in Malayalam theatre. This project aims to shed some light on a rare series of political plays from Malayalam theatre which was moving parallel to the dominant political ideologies of the state. Sometimes Malayalam theatre favoured the communist movement while in some other cases it took anti-communist positions. This series of play texts includes Thoppil Bhasi’s Ningalenne Communistakki (You Made Me a Communist) (1952) as the source play and Jnanippakkammoonishtavum (I Will Become a Communist Now) (1953) by Kesava Dev, Vishavriksham (Poisonous Tree) (1958) by C. J. Thomas, Ningalaare Communistakki (Whom Did You Make a Communist) (1995) by Civic Chandran, Ningalenne Communistakki Indra Sadassil (You Made Me a Communist in Paradise) (2004) and Enum Ente Thambranum (Me and My Lord) (2008) by Thoppil Soman as counter plays.
