Mundkur Memorial Award Lecture - Integrated management of potato Sclerotium wilt caused by Sclerotium rolfsii
K.H. ANAHOSUR
Indian Phytopathology , 2012,
Abstract: At the outset I offer my gratitude to the Indian Phytopathological Society for having given me this opportunity to deliver the Mundkur Memorial Lecture. I consider it both a privilege and honour. My teachers during my graduating programme in early sixties in Plant Pathology courses narrated the great contributions of Dr. Mundkur for the development of Plant Pathology in India. Also, I was taken to the place near Dharwad where Dr. Mundkur worked as Assistant mycologist in Cotton Research Station and his contributions were so impressive that I decided to opt for post graduate programme in Plant Pathology. I was very much impressed by his work pertaining to practical aspect and location specific problems of farmers. I salute Dr. Balachandra Bhavanishankar Mundkur whose work on plant pathology very much impressed and thus inspired me to take plant pathology as a career. Therefore, now I have choosen to talk on a topic which is location specific, problem of the farmers and economically significant. Also this approach of IDM for a soil borne polyphagous and pleurivorus pathogen would be an inspiration to the young scientists to develop similar IDM to solve the different problems. The topic is "Integrated Management of the Potato Sclerotium wilt caused by Sclerotium rolfsii " .
Accessibility of most frequently used physical parameters of soil structure, reliability of measured values, lack of replicates and ways out of this dilemma
Hartge K.H.
International Agrophysics , 1997,
Abstract: Assessment of soil structure and still more its changes is impeded by peculiarities of sampling and measurement. Unavoidable local destructions tend to advance use of small numbers of replicates, samples or sampling locations. Ways out of this dilemma are discussed using the results which were obtained in the project 'Qualitative and quantitative assessment of soil structure functions for the sustainable agricultural plant production'. Bulk density(BD) and saturated hydraulic conductivity (CSAT) are the most frequently used primary parameters of soil structure. The stastistical behaviour of these both is most different. High variability of CSAT usually precludes measurement at a sufficient number of replicates for statistic analysis - particularity at soil depths below topsoil. BD has smaller variability but much smaller sensitivity as well. For measurements at greater depths in soils it is preferable nevertheless owing to the lower number of necessary replicates. A two-level outflanking procedure might facilitate sampling problems by first applying an easy-going nondestructive, unspecific method to create a narrow grid of values as a first step which might help to rationalize choice of sampling locations for destructive samplings and in-situ measurements.

Towards Unifying Structures in Higher Spin Gauge Symmetry
Anders K.H. Bengtsson
Symmetry, Integrability and Geometry : Methods and Applications , 2008,
Abstract: This article is expository in nature, outlining some of the many still incompletely understood features of higher spin field theory. We are mainly considering higher spin gauge fields in their own right as free-standing theoretical constructs and not circumstances where they occur as part of another system. Considering the problem of introducing interactions among higher spin gauge fields, there has historically been two broad avenues of approach. One approach entails gauging a non-Abelian global symmetry algebra, in the process making it local. The other approach entails deforming an already local but Abelian gauge algebra, in the process making it non-Abelian. In cases where both avenues have been explored, such as for spin 1 and 2 gauge fields, the results agree (barring conceptual and technical issues) with Yang-Mills theory and Einstein gravity. In the case of an infinite tower of higher spin gauge fields, the first approach has been thoroughly developed and explored by M. Vasiliev, whereas the second approach, after having lain dormant for a long time, has received new attention by several authors lately. In the present paper we briefly review some aspects of the history of higher spin gauge fields as a backdrop to an attempt at comparing the gauging vs. deforming approaches. A common unifying structure of strongly homotopy Lie algebras underlying both approaches will be discussed. The modern deformation approach, using BRST-BV methods, will be described as far as it is developed at the present time. The first steps of a formulation in the categorical language of operads will be outlined. A few aspects of the subject that seems not to have been thoroughly investigated are pointed out.
Domestic and supranational political opportunities: European protest in selected countries 1980-1995
Uwe K.H. Reising
European Integration Online Papers , 1998,
Abstract: This paper attempts to explain the rates of European protest in three core countries of the EEC/EU the Belgium, France, and Germany over a sixteen-year period from 1980 to 1995 based on their institutional differences as suggested by the literature on political opportunity structures. First, the findings support the notion of a Europeanization of protest that is spurred by the changing constellation of national vs. supranational powers in the wake of European integration. The Europeanization of protest occurs, displaying systematic cross-national differences. These differences are, as the results suggest, related to the differential between the constraints of the actors' domestic environments and the common-to-all evolving opportunities on the level of European politics. Secondly, the findings suggest that the rates of protest in cross-national perspective are not simply random. The macro-political structure plays a (statistically) significant, logically consistent, and visible role in the explanatory bundle leading to occurrence or absence of protest actions.
