If we think of the graph as modeling a network, the vulnerability measure the resistance of the network to disruption of operation after the failure of certain stations or communication links. Many graph theoretical parameters have been used to describe the vulnerability of communication networks, including connectivity, integrity, toughness, binding number and tenacity.In this paper we discuss...

Plasmids were constructed which contained a large portion of each of the four nonstructural genes of Sindbis virus fused to the N-terminal two-thirds of the trpE gene of Escherichia coli. The large quantity of fusion protein induced from cells containing these plasmids was subsequently used as an antigen to generate polyclonal antisera in rabbits. Each antiserum was specific for the correspondi...

In order to increase our understanding of the assembly of the capsid proteins of AHSV, for the development of subunit vaccines and to study viral morphogenesis, it is necessary to investigate the interaction of the four major structural proteins of AHSV in the absence of other AHSV proteins and the viral genome. To investigate particle formation it was necessary to synthesise the proteins of in...

The study investigated the effect of Community-Based Paid Extension (CPE) on vulnerability reduction of smallholder dairy farmers. Randomly sampled 255 farmers were interviewed together with 15 key informants’ interview. Both statistical analysis and thematic approach were employed to achieve triangulation. In about 68 % of cases, CPE reduced vulnerability to a degree experienced as ‘moderate’,...

In this work, a new methodology to estimate the functional vulnerability of road network city Catania (Italy) is developed with purpose improve resilience urban transport during critical events. While traditional approach for estimation based on topological data, proposed spatial-temporal mobility profiles obtained floating car data (FCD). The algorithm combines properties patterns from FCD eva...
