in order to determine probable effects of sowing dates on partitioning coefficient of dry matter to different organs (leaf, stem and reproductive organs) in different wheat varieties (koohdasht, zagros and tajan) an experiment with crbd design and four replications was conducted. 5 sowing dates were included (29 december, 2007, 30 january, 2 march, 27 march, 1may, 2008). in order to quantify pa...

The bioaccumulation of estrone by Daphnia magna was determined. Direct uptake via the aqueous medium occurred within the first 16 h. A bioconcentration factor of 228 was established over all temporal periods. Ingestion via Chlorella vulgaris gave a partitioning factor of 24, which may approximate to a biomagnification factor assuming steady state conditions. These preliminary results indicate t...

Given d-dimensional N data items and a maximum branching factor Bfmax, packing is partitioning Bfmax amount of data and storing it in a disk page. The range query performance of packing is highly dependent on the methods by which data is partitioned. Thus, partitioning data is the main problem tackled in our work. We suggest two extreme cases of partitioning methods: grid-like balanced and onio...

We consider the problem of NON-UNIFORM GRAPH PARTITIONING, where the input is an edge-weighted undirected graph G = (V,E) and k capacities n1, . . . , nk, and the goal is to find a partition {S1, S2, . . . , Sk} of V satisfying |Sj | ≤ nj for all 1 ≤ j ≤ k, that minimizes the total weight of edges crossing between different parts. This natural graph partitioning problem arises in practical scen...

In this paper we present a pilot implementation of the Meta-Partitioner, a partitioning framework that automatically selects, configures, and invokes suitable partitioning algorithms for Structured Adaptive Mesh Refinement (SAMR) applications. Efficient use of SAMR on parallel computers requires that the dynamic grid hierarchy is repeatedly repartitioned and redistributed. The partitioning proc...

Processing a federated query in Linked Data is challenging because it needs to consider the number of sources, the source locations as well as heterogeneous system such as hardware, software and data structure and distribution. In this work, we investigate the relationship between the data distribution and the communication cost in a federated SPARQL query framework. We introduce the spreading ...

this experiment aimed to investigate the effect of (zero, 20, 40 and 60 mg/kg atriplex forage) malva sylvestris on digestibility and microbial fermentation of atriplex in one-humped camel. fermentation parameters by gas production technique and in vitro digestibility by two-stage digestion were measured by two years old female fistulated camels. addition 40 and 60 mg/kg malva sylvestris increas...
