Physicochemical and Genetic Analysis of an Endemic Rice Variety, Njavara (Oryza sativa L.), in Comparison to Two Popular South Indian Cultivars, Jyothi (PTB 39) and IR 64
No full textNjavara is a medicinal rice strain, endemic to Kerala, South India, bestowed with medicinal qualities.
Genetic variations and some of the physicochemical properties were studied using standard
molecular protocols and compared with those of nonmedicinal rice varieties: Jyothi and IR 64.
Njavara showed 11 unique positive and 36 unique negative markers to differentiate it from Jyothi
and IR 64. Genetic similarity coefficient studies showed two well-defined clusters separating Njavara
from Jyothi and IR 64. All the three varieties had waxy gene Wxa allele. Njavara had (CT)n repeats
at (CT)10, while Jyothi and IR 64 had repeats at (CT)11 in the 50-untranslated region of waxy gene.
Njavara showed a CGTG sequence, while Jyothi and IR 64 had a CGCG sequence at the 14th exon
of Sbe 1 gene. Njavara, Jyothi, and IR 64 have similar amylose equivalent (AE), which was
confirmed by microsatellite markers. The SSR primers for protein content and setback viscosity
primer (RM 4608) were observed to be polymorphic in case of Njavara. Njavara rice, with a distinct
gene pool and medicinal properties, can be exploited as a nutraceutical rice
Chitosan and Starch-Based Hydrogels Via Graft Copolymerization
No full textGraft copolymerization is an attractive method for surface functionalization of natural polymers and can be
initiated by chemical methods, radiation technique, and other systems. Polymer grafting onto
polysaccharides is an effective method for the synthesis of superabsorbents. Depending upon the type of
monomers and the conditions employed the properties of graft copolymers vary to a large extent. Chitosan
is a nontoxic, biocompatible polysaccharide, and starch is a natural hydrophilic biopolymer. Both these are
most abundant natural organic materials which are extensively investigated in the development of
biodegradable and environment-friendly materials. Their hydrogels are of utmost importance for wide use
in many fields including structural transplants, target drug delivery, tissue engineering, biosensors,
adsorbents, etc. In this chapter, the various techniques used for the synthesis of chitosan/starch graft
copolymers, their properties and possible applications are discussed in detail
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)

Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
