Incidents of nuclear and radiological smuggling in the Indian Ocean are a matter of concern. Attempts to smuggle nuclear material within India have also been reported as recently as 2021. Indian security agencies previously have also seized natural uranium in coastal states such as Gujarat, Maharashtra and Bengal indicating how vulnerable the Indian coast is to radiological and nuclear smuggling. The Nuclear Security Index has also consistently ranked India below China and Pakistan despite their poor record on nuclear non-proliferation. These facts highlight concerns regarding the possible misuse of nuclear and radiological material by criminal and terrorist networks. Since India is targeted by terrorist groups and lies in the vicinity of countries and routes that see frequent nuclear and radiological trafficking, there are inevitable implications for the Indian coastal security system. This article identifies and analyses these security implications and argues for a beefing up of India's coastal security. [ABSTRACT FROM AUTHOR]

This article assesses mainstream sociolinguistic theory and methods in the context of world Englishes. Despite its obvious applicability, sociolinguistic theory has not always been the primary analytic model for world Englishes. The multilingual and sometimes mobile circumstances of world Englishes contexts do not always fit the usual definition of a Labovian speech community. This article extends classic sociolinguistic theory and method to studies of Outer Circle English situations to test their validity and scope. Predictions for class, gender, age, peer effects and identity are assessed, all initially developed in monolingual urban Western contexts. Methodological constructs such as apparent time, the sociolinguistics interview and social network metrics are also critically evaluated. The discussion shows that, although these new contexts challenge claims of universality, they often also uphold the original insights. A falsifiable theory of sociolinguistic variation and associated methods remain crucial for a principled understanding of variation and change in world Englishes. [ABSTRACT FROM AUTHOR]

Amoebic liver abscess (ALA) is commonly seen in tropical countries and diagnosis of ALA relies mainly on non-specific serological and imaging techniques as well as PCR from pus. This study evaluated the potential of using cell free DNA (cfDNA) from serum and urine for diagnosing ALA. We prospectively evaluated quantitative PCR (qPCR) for detection of cf DNA in serum and urine sample in all liver abscess patients. The samples were collected from patients reporting to emergency ward of Postgraduate Institute of Medical Education and Research, Chandigarh, India with symptoms suggestive of liver abscess. Real time PCR was done to detect cf DNA in serum and urine by targeting 99-bp unit of small subunit rRNA of Entamoeba histolytica and conventional PCR for pus. A total 113 samples (serum and urine) and 100 pus samples were analysed. A total of 62 ALA patients were confirmed; with maximum 57 patients detected by qPCR for cfDNA in the serum, 55 patients by PCR on pus aspirate and 50 ALA patients by qPCR for cfDNA in urine sample. Therefore, the sensitivity of qPCR for detection of cf DNA in serum was 91.94% and for urine was 80.65%. A total of 11.2% of ALA patients were diagnosed only through detection of E. histolytica cf DNA in their serum and urine. Detection of cfDNA from serum, urine of ALA has a potential role in future especially for developing countries as it is a rapid, sensitive and patient friendly diagnostic approach.

Stable nonnative varieties of English acquired and used in the absence of native English input can diverge systematically from native varieties over time (Cheshire, 1991; Kachru, 1983; Platt, Weber, & Ho, 1984). Focusing on Indian English article use, this study asks the following question: If divergence is indeed occurring, do new features derive primarily from first language (L1) transfer or from universal principles? Natural conversational speech is assessed in relation to four hypotheses relating to L1 transfer and language universals, and a multivariate regression analysis evaluates the relative strength of each factor. The new article system is not found to be identical to the L1 article system. Although L1 transfer appears to be operative when an overt form (the specific indefinite article) exists in the L1, when a gap occurs in the L1 (no definite article), speakers do not completely omit the definite article in their second language English. Using Prince's (1981) taxonomy of assumed familiarity, it is shown that the absence of a L1 model for definite articles permits the intervention of universally available discourse knowledge, such that speakers apply an economical, disambiguating principle to the use of overt articles, reserving them mainly for new (less given or inferable) information and omitting them in more redundant contexts.

Examines a case of dialectal variation in a subpart of the tense-modality aspect system of Indian English. Focuses on functions associated with an existing form: the use of the pluperfect "had" + V-"ed" construction. Contrasts this usage with that of British and American English. (Author/VWL)
