Delay Tolerant Networks (DTNs) are characterized by large delays, frequent disruptions and lack of contemporaneous paths between nodes. Moreover, nodes may have limited computational power, storage, and battery capacity. Despite these challenges, DTNs have found applications in areas such as animal tracking, surveillance and facilitating education in remote areas. In these applications, a criti...

Cowpea (Vigna unguiculata (L.) Walp.) is one of the most important grain legumes in sub-Saharian regions. It contributes to man food security by providing a protein-rich diet. However, its production is limited by abiotic stresses such as salinity. This study aims to evaluate the salt tolerance of 15 cowpea cultivars, at germination stage. The seed germination process consisted of sowing them i...

In a resource constrained network such as Delay Tolerant Networks (DTN), efficient utilization of resources such as energy is important for optimum network performance. However, due to nodes mobility, frequency of encounters and message transmission, most of node’s energy in this type of network is continuously depleted. A node’s energy in DTN plays an important role in the success of deliverin...

salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

selection and use of tolerant grapevine as rootstock or own-rooted vines and finding indexes for screening of resistant genotypes have especial importance. to identify the salt tolerant grapevine genotypes, effects of nacl concentrations (0, 50, 100 and 150 mm) on root length, root and shoot dry weight, prolin, total soluble solid, rwc, level of salt injury, leaf concentration of k, na, cl and ...

Maize is moderately sensitive to salt stress; therefore, soil salinity is a serious threat to its production worldwide. Here, excellent salt-tolerant maize inbred line TL1317 and extremely salt-sensitive maize inbred line SL1303 were screened to understand the maize response to salt stress and its tolerance mechanisms. Relative water content, membrane stability index, stomatal conductance, chlo...

In this paper, we study cost efficient multi-copy spraying algorithm for routing in Delay Tolerant Networks (DTN) in which source-to-destination path does not exist most of the time. We present a novel idea and the corresponding algorithm for achieving the average minimum cost of packet transmission while maintaining the desired delivery rate by the given deadline. The number of message copies ...

Salt-tolerant alkaliphilic actinomycetes are difficult to isolate as their natural environments are much more different and hostile than laboratory conditions. Due to these limitations, majority of the microbial population remain uncultivated. During the recent years, development and application of molecular techniques, such as; DGGE, TGGE, RFLP and DNADNA hybridization have proved quite valuab...

I have selected salt-tolerant cell lines from salt-sensitive cell cultures to identify genes that can contribute to longt e m increased salt tolerance in alfalfa (Medicago sativa L.). Comparisons of differential gene expression in response to salt within the same genetic background allowed me to identify gene products that showed salt-induced expression in those cells with acquired salt toleran...
