Scalable and efficient broadcast is essential to the large-scale computing infrastructures such as PlanetLab and Grids. By exploiting the greedy routing mechanisms of Distributed Hash Table (DHT), existing DHTbased broadcast algorithms suffer from the limitations of scalability and load balancing, incurring high construction and maintenance overhead for a distributed broadcast tree (DBT). This ...

the effect of ca, zn and b foliar application (five g l-1) and their mixed applications as well as two harvest dates (1st and 15st of august) on ppo activity of two commercial asian pears (‘ks’9 and ‘ks’13) fruits at the time of harvest and during storage were investigated. results showed that the ppo activity increased from harvest time to three months after storage and then decreased. during ...

'!he results obtained so far in this 3 year study have shown that the plots with poisoned bait feeder stations suffered significantly less tree girdling than the plots treated with the fall broadcast application of 2% zinc phosphide. Similar timings were also observed in number of voles per plot, however, the vole population was much lower than the previous year. Cbnsiderable interest has been ...

abstract- the effects of iron (fe) and zinc (zn) treatments on the growth and nutrient composition of chickpea were studied in a greenhouse experiment arranged in a completely randomized design. while the application of fe decreased mean shoot dry weight of chickpea, that of zn had no significant effect on chickpea shoot dry weight. increasing fe levels drastically decreased mn concentration an...

Little attention has been paid to the diagnosis of deficiencies of micronutrients such as zinc (Zn) and boron (B) and secondary nutrient such as sulphur (S) in rainfed systems. We evaluated Zn, B and S status of 1617 farmers’ fields in 14 districts of the semi-arid tropical India. Results showed that most of the soil samples were low to medium in organic carbon contents. Results also revealed t...

We explore in this paper the problem of generating hierarchical broadcast programs with the data access frequencies and the number of broadcast disks in a broadcast disk array given. Specifically, we first transform the problem of generating hierarchical broadcast programs into the one of constructing a channel allocation tree with variant-fanout. By exploiting the feature of tree generation wi...

nitrate and ammonium forms of nitrogen are being applied to improve plant growth and uptake of other nutrients. given that the effect of application of different nitrate to ammonium ratios accompanied by other fertilizers (i.e. fe, mn and zn) has not been studied on wheat growth as well as uptake of fe, mn and zn, three glasshouse pot studies were conducted with factorial arrangement of treatme...

Wireless sensor networks (WSNs) have been the focal point of research over the last several years. Broadcast communication is a key requirement for WSNs since many tasks in the network depend on broadcasting, including critical tasks like querying. Consequently, securing broadcast communication over sensor networks has become an important research challenge. Typically, broadcast communication i...
