Coastal Bio-shields and their Putative Role During Large Weather Related Disturbance Events IN: Bhalla, R.S, Ram, Sunita and Srinivas, V. (eds) Studies on Vulnerability and Habitat Restoration along the Coromandel Coast
Full text link[Extract] 4.1 Background
Even four years after the Indian Ocean tsunami, one of the most widely debated topics has been the role of coastal vegetation in mitigating impacts of the tsunami. Following the aftermath, several publications, both in scientific journals and popular media (Anonymous, 2005; Ganesan, 2005; Kar and Kar, 2005; Kathiresan and Rajendran, 2005; Kumar, 2005; Anonymous, 2006; Dahdouh-Guebas et al., 2006; Raghunathan, 2006; Vermaat and Thampanya, 2006; Olwig et al., 2007), staked claims on the positive and protective role coastal vegetation provided in the event of such large scale natural disasters (see Mukherjee et al., 2007b for a compilation). Piloted and supported by this, huge amounts of money was spent in creating bio-shields along coastal stretches to act as natural defences against events like the tsunami (Mukherjee et al., 2007b). While these modifications to coastal stretches were being implemented, a few studies indicated that coastal vegetation had very little or no protective role to play in the events like the tsunami (Kerr et al., 2006; Bhalla, 2007; Madhusudan et al., 2007; Mukherjee et al., 2007b) and suggest that the role of other coastal features like topography, near shore bathymetry, distance to continental shelf, etc. need to be considered as variables that explain the observed inundation distances
Physical properties of amorphous Al-Gd-transition metal alloys
No full textAmorphous alloys of the composition Al65Gd15Cu20 and Al1Gd1Fe1 have been prepared by rapid quenching from the melt. The alloys have been studied by X-ray diffraction, thermal analysis and SQUID magnetization methods. Thermal analysis results show crystallization temperatures of 647 and 945 K for Al-Gd-Cu and Al-Gd-Fe, respectively. For Al-Gd-Cu, magnetization measurements show Curie-like behaviour with a localized Gd magnetic moment of 8.0mu(B). Magnetic measurements of Al-Gd-Fe show conventional ferromagnetic behaviour. The Curie temperature is found to be 275 K and a saturation magnetization of 124 emu/g is measured at 4.2 K in an applied magnetic field of 1 T.PT: J; CR: DUNLAP RA, 1989, PHYS REV B, V39, P4808 DUNLAP RA, 1990, J PHYS CONDENS MATT, V2, P4315 DUNLAP RA, 1990, UNPUB HE Y, 1988, SCIENCE, V241, P1640 INOUE A, 1981, J MATER SCI, V16, P1989 INOUE A, 1988, JPN J APPL PHYS, V27, P1796 INOUE A, 1988, JPN J APPL PHYS, V27, L1579 INOUE A, 1988, JPN J APPL PHYS, V27, L479 OHANDLEY RC, 1991, HDB MAGNETIC MATERIA, V6, P453 SRINIVAS V, 1990, J APPL PHYS, V67, P5879 SUZUKI RO, 1985, J MATER SCI, V18, P1195 YEWONDWOSSEN M, 1990, THESIS DALHOUSIE U YEWONDWOSSEN M, 1992, J PHYS-CONDENS MAT, V4, P461; NR: 13; TC: 1; J9: J NON-CRYST SOLIDS; PN: Part 1; PG: 3; GA: LC964Source type: Electronic(1

Understanding the Evolution of Plant Growth-Promoting Rhizobacteria
Full text linkSoil is an integral part of the complicated natural environment which is
very much alive with complex ecosystem of microbes. Among them, the symbiotic
association of rhizobacteria with plants especially on agriculturally important crops
is very much advantageous in improving the soil and plant health. These plant
growth-promoting rhizobacteria (PGPR) have evolved over the years and involved
in many plant functions such as growth promotion, root development, colonization,
production of metabolites and in eliciting plant defence mechanism against abiotic
and biotic agents. The PGPR’s ability to fix the atmospheric nitrogen, solubilize
phosphate, potassium and zinc, produce siderophore along with wide variety of
phytohormones and secondary metabolites such as antibiotics have attributed to their
significance as biocontrol agents. These functions lead to their application as
biofertilizers, biopesticides, bioprotectants and phytostimulators. The employment
of these PGPR is very much important in agricultural fields as they reduce the burden
of chemical fertilizers and pesticides to the farmers and in turn promises an increased
crop yield. This chapter discusses the symbiotic association of PGPR with plants in
detail including their direct and indirect mechanisms and basis of their induced
systemic defence mechanism. It also highlights the use of bioinoculants and nanoformulations
of PGPR as an effective tool towards enhanced agricultural production
and to combat the plant diseases in an eco-friendly manner
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
