Comparative performance of Vanaraja, Srinidhi and Desi chicken under traditional system among tribal community of Assam
No full textA study was conducted covering a total of one hundred chicken farmers in tribal dominated Boko Block of Kamrup district in Assam to assess different productive and reproductive traits of Desi, Vanaraja and Srinidhi birds under field condition. Information was obtained on mean body weight at various ages, age at first egg, annual egg production, fertility and hatchability and mortality rate. Body weight, egg production and egg weight were significantly (P£0.05) higher in Vanaraja and Srinidhi birds compared to Desi chicken. The age at first egg was significantly (P£0.05) higher in Desi chicken while compared with Vanaraja and Srinidhi under traditional system of management. However no significant (P£0.05) difference was found between Vanaraja and Srinidhi in their body weight and egg production at various ages. Higher mortality percent in Vanaraja (12.23±1.62) and Srinidhi (11.34±1.23) were recorded during 0 to 5 week. No significant (P£0.05) differences were found among all three groups of birds in fertility and hatchability.</jats:p
Patterns of electro-magnetic response in topological semi-metals
Get PDFTopological semimetals are gapless states of matter which have robust and unique electromagnetic responses and surface states. In this thesis, we consider semimetals which have point like Fermi surfaces in various spatial dimensions which naturally occur in the transition between th order weak topological insulators and a trivial insulating phase. These semimetals include those of Dirac and Weyl type. We construct these phases by layering strong topological insulator phases in lower dimensions. This perspective helps us understand their effective response field theory, which is generally characterized by a -form which represents a source of Lorentz violation and can be read off from the location of the singular points in momentum space and the helicities/chiralities of the singularities. We motivate and derive effective response actions for the 2D and 3D Dirac semi-metals, the Weyl semimetal, the 3D line node semi-metal and the 3D mirror protected topological crystalline insulator.Submission original under an indefinite embargo labeled 'Open Access'.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Determination of Methods for Improved Reprogramming of Various Cell Types to Functional Beta-like Cells
No full textUniversity of Minnesota M.S. thesis. December 2016. Major: Stem Cell Biology. Advisor: James Dutton. 1 computer file (PDF); vii, 45 pages.Reprogramming is the process of converting a somatic cell into a different cell type in a controlled manner without an intermediate pluripotent state, usually by expression of exogenous transcription factors. Here, 3 transcription factors, (Pdx1, Ngn3 and MafA) incorporated in a polycistronic adenoviral vector system (Ad-PNM) was used to directly reprogram cells to beta-like cells that produce insulin in vitro. In addition, the role of innate immunity activation and open chromatin structure during reprogramming is studied to improve overall reprogramming efficiency while using the Ad-PNM adenoviral vector.Sripathy Rao, Srinidhi Rao.

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
