      • Indus Script:

        Nisha Yadav,M. N. Vahia 훈민정음학회 2011 Scripta Vol.0 No.3

        The Indus script is an undeciphered script of the ancient world. In spite of numerous attempts over several decades, the script has defied universally acceptable decipherment. In a recent series of papers (Yadav et al. 2010; Rao et al. 2009a, b; Yadav et al. 2008a, b) we have analysed the sequences of Indus signs which demonstrate presence of a rich syntax and logic in its structure. Here we focus on the structural design of individual signs of the Indus script. Our study is based on the sign list given in the concordance of Mahadevan (1977) which consists of 417 distinct signs. We analyse the structure of all signs in the sign list of Indus script and visually identify three types of design elements of Indus signs namely basic signs, provisional basic signs and modifiers. These elements combine in a variety of ways to generate the entire set of Indus signs. By comparing the environment of compound signs with all possible sequences of constituent basic signs, we show that sign compounding (ligaturing) and sign modification seem to change the meaning or add value to basic signs rather than save writing space. The study aims to provide an understanding of the general makeup and mechanics of design of Indus signs.

      • Sensitivity of Indus Script to Site and Type of Object

        Nisha Yadav 훈민정음학회 2013 Scripta Vol.0 No.5

        The Indus valley civilisation (2600 to 1900 BCE) left behind its undeciphered script on several small, inscribed objects. In our earlier work, we have investigated the structural aspects of the Indus script, the design of its signs and the nature of the inscribed patterns on these objects. Here we study these inscribed objects with respect to their type and the sites where they were found. The distribution of the text lengths and the usage of signs on these objects indicate subtle variations in the context of their site of occurrence and type. Some signs have affinity to specific sites or types of objects. By comparing the text length distributions and the usage of signs on these inscribed objects, we cluster the sites of occurrence and the types of objects based on their level of similarity. The study provides an understanding of the sensitivity of the Indus script to different sites and types of objects.

        Patient Knowledge, Attitude and Perceptions towards Botulinum Toxin Treatment for Movement Disorders in India

        Thavasimuthu Nisha Mol,Nitish Kamble,Vikram V. Holla,Rohan Mahale,Pramod Kumar Pal,Ravi Yadav 대한파킨슨병및이상운동질환학회 2021 Journal Of Movement Disorders Vol.14 No.2

        ObjectiveaaThere is limited literature on the knowledge, attitude, and perceptions (KAP) of botulinum toxin (BoNT) treatmentamong patients and caregivers. The objective of this study was to assess the KAP in patients undergoing BoNT treatment for movementdisorders. MethodsaaOne hundred patients with movement disorders from National Institute of Mental Health and Neurosciences Hospitalin Bengaluru, South India, were recruited. The patients underwent demographic, clinical, and Patient Knowledge Questionnaireon Botulinum Toxin Use in Movement Disorders (PKQ-BMD)-based evaluations. ResultsaaThe mean age of patients at the time of presentation was 47.97 ± 14.19 years (range, 12–79). Of all the patients, 26 (28%)patients were anxious, and 86% of these patients were reassured after appropriate counseling. There were 83 (89%) patients whofound BoNT to be a costlier option. Education and previous Internet searches influenced positive performance in the “knowledge”domain and overall PKQ-BMD scores. The “number of injections” was also positively correlated with KAP performance. ConclusionaaThis study showed that knowledge and perceptions about BoNT treatment need to be further improved. Wideravailability of the Internet has provided a positive impact on patients’ and carers’ KAP. Internet-based information, higher educationalqualifications of the patients, and a higher number of BoNT injection sessions are the most important predictors of satisfactoryKAP related to BoNT injection treatment in patients with movement disorders

        Assessment of Bioremediation Potential of Cellulosimicrobium sp. for Treatment of Multiple Heavy Metals

        Bhati, Tushar,Gupta, Rahul,Yadav, Nisha,Singh, Ruhi,Fuloria, Antra,Waziri, Aafrin,Chatterjee, Sayan,Purty, Ram Singh The Korean Society for Microbiology and Biotechnol 2019 한국미생물·생명공학회지 Vol.47 No.2

        In the present study, we have studied the bioremediating capability of bacterial strain against six heavy metals. The strain was isolated from river Yamuna, New Delhi which is a very rich repository of bioremediating flora and fauna. The strain was found to be Gram positive as indicated by Gram staining. The strain was characterized using 16s rRNA gene sequencing and the BlastN result showed its close resemblance with the Cellulosimicrobium sp. As each treatment has its own toxicity eliciting expression of different factors, we observed varied growth characteristics of the bacterial isolate and its protein content in response to different heavy metals. The assessment of its bioremediation capability showed that the strain Cellulosimicrobium sp. has potential to consume or sequester the six heavy metals in this study in the following order iron > lead > zinc > cooper > nickel > cadmium. Thus, the strain Cellulosimicrobium sp. isolated in the present study can be a good model system to understand the molecular mechanism behind its bioremediating capabilities under multiple stress conditions.
