phenotypic and genotypic diversity as well as symbiotic effectiveness of twenty one symbionts isolated from nodules of four acacia species (acacia melanoxylon, a. mearnsii, a. saligna and acacia tortillis) grown in morocco were evaluated. growth in various media (yma, yma-bbt, yma-rc), colony morphology, tolerance to stress factors (temperature, ph, salt concentrations, various heavy metals) an...

The nuclear site of Sellafield in West Cumbria, North England, embarks on a long period decommissioning. Limited (SL), the government-owned company running site, is intent disentangling strong socioeconomic and affective relations with its host area view to making Cumbria less dependent SL, area’s major employer, as prepares for slow withdrawal. Comparing whale fall, habitat that comes into bei...

This paper addresses cooperative operation of symbiotic human-robot system. In order to implement cooperative operation, symbiotic human-robot system is modeled using frame-based knowledge representation. According to this knowledge model, the system is defined in the Software Platform of Agents and Knowledge Management (SPAK). With the support of SPAK, cooperative operation can be therefore ca...

Logic1 GLARF relations are generated from treebank and parses for English, Chinese and Japanese. We focus on evaluation of system output for both input types, often allowing for multiple correct answers.

We present and discuss a simple semantic approach to force step-indexed logical relations to be transitive.

We investigatea simple form of parametricity, based on adding \abstract" copies of pre-existing types. Connections are made with the Reynolds-Ma theory of parametricity by logical relations, with the theory of parametricity via dinaturality, and with the categorical notion of equivalence.

Since the Meiji Restoration, Japan and France have experienced a special relationship led by strong cultural economic ties. The present paper analyses their during second administration of former prime minister Japan, Abe Shinzō. focuses on respective security trends. Security is studied as a(n inter-)subjective dynamic process. For this reason, Copenhagen School’s ‘securitisation’ will serve t...

*Internet Systems Research Laboratories †Vice President, Central Research Laboratories This paper presents the concept of symbiotic evolution which aims to provide a better individual quality of life as well as an improved standard of work. Symbiotic evolution is a co-evolution process linking human activities and ubiquitous systems. We also discuss key technical challenges explaining three res...

Recent maser surveys have shown that many potential OH/IR stars have no OH masers in their circumstellar envelopes, despite the modest requirements which should be implicitly met by IRAS colour-selected candidates. It has been suggested that these OH/IR colour mimics must have a degenerate companion which dissociates OH molecules and disrupts the masing action, ie. that they are related to symb...

A Tnt1-insertion mutant population of Medicago truncatula ecotype R108 was screened for defects in nodulation and symbiotic nitrogen fixation. Primary screening of 9,300 mutant lines yielded 317 lines with putative defects in nodule development and/or nitrogen fixation. Of these, 230 lines were rescreened, and 156 lines were confirmed with defective symbiotic nitrogen fixation. Mutants were sor...
