In this paper, a multi label variant of CLUBAS [1] algorithm, ML-CLUBAS (Multi Label-Classification of software Bugs Using Bug Attribute Similarity) is presented. CLUBAS is a hybrid algorithm, and is designed by using text clustering, frequent term calculations and taxonomic terms mapping techniques, and is an example of classification using clustering technique. CLUBAS is a single label algorithm, where one bug cluster is exactly mapped to a single bug category. However a bug cluster can be mapped into the more than one bug category in case of cluster label matches with the more than one category term, for this purpose ML-CLUBAS a multi label variant of CLUBAS is presented in this work. The designed algorithm is evaluated using the performance parameters F-measures and accuracy, number of clusters and purity. These parameters are compared with the CLUBAS and other multi label text clustering algorithms.

The particle flow pattern, mixing and granule segregation in a tapered fluidized bed have been studied along with the hydrodynamics. At first the bed of varying total mass and granule fractions is fluidized then the bed is defluidized to freeze the composition, the bed is sectioned to layers and the composition in each layer is determined by sieving. Materials used in the present study are dolomite and glass beads with different B.S.S Sizes. A series of unsteady, three fluid CFD simulations were performed using FLUENTTM 6.2. Simulation parameters viz. solution technique, grid, maximum packing fraction and operating conditions like gas velocity were investigated for relative effects on particle mixing and segregation. Good arrangement of solid volume fraction profile was obtained between the experimental results and simulation results for regular particles.

To enhance the antifungal response of litchi, transferring rice chitinase gene under a maize-ubiquitin promoter along with its first intron into the zygotic embryos via Agrobacterium tumefaciens-mediated transformation generated transgenic plants. After co-cultivation for 2 days with recombinant Agrobacterium, zygotic embryos were transferred onto Murashige and Skoog (MS) medium consisted of MS salts and Gamborg (B5) vitamins with 2 mgl-1 2, 4-dichlorophenoxyacetic acid (2, 4-D), 50 gl-1 sucrose and 8 gl-1 agar supplemented with 25 mgl-1 hygromycin and 400 mgl-1 cefotaxime. Embryos were selected passing through a series of MS modified media and the antibiotic resistant transgenic plantlets were analyzed. The integration and stability of the transgene was confirmed by PCR, RT-PCR, Southern blotting and by Western blot analyses. The transgenic plants exhibited higher chitinase activity than the non-transformed plants. The chitinase activity was also examined using the native polyacrylamide in-gel assay. These analyses indicated that the foreign gene was translated into the protein of expected molecular weight that showed chitinase activity. Following in-vitro inoculation of die-back, leaf spots and blight pathogen (Phomopsis sp.), the transgenic plants showed delayed onset of the disease and smaller lesions. The transgenic plants were adapted to the greenhouse and did not show any phenotypic alterations.

Recently in [1] Goyal and Agarwal interpreted a generalized basic series as a generating function for a colour partition function and a weighted lattice path function. This led to an infinite family of combinatorial identities. Using Frobenius partitions, we in this paper extend the result of [1] and obtain an infinite family of 3-way combinatorial identities. We illustrate by an example that our main result has a potential of yielding Rogers-Ramanujan-MacMahon type identities with convolution property.

This paper presents a record of radiolarian species from the sections (1H1-1H2) Leg 119 Site 738B of Southern Ocean region. Well diversified taxa of typical Antarctic assemblage are present in the sections. Thirty species were identified and illustrated from twenty-nine samples. On the basis of appearance, disappearance and abundance of taxa, viz. Omega and Psi zones are established and systematics of stratigraphically important species is described. These zones are equivalent to NR1 and NR2 of Upper Quaternary.

At least six major genotypes of Hepatitis C virus （HCV） cause liver diseases worldwide. The efficacy rates with current standard of care are about 50% against genotype 1, the most prevalent strain in the United States, Europe and Japan. Therefore more effective pan-genotypic therapies are needed. HCV RNA replication provides a number of validated targets for virus-specific and potentially pan-genotypic inhibitors. In vitro assays capturing the different steps of RNA synthesis are needed not only to identify new inhibitors, but also to examine their mechanisms of action. This review attempts to provide a comprehensive summary of the biochemical, cell-based and animal model systems to assess HCV polymerase activity and HCV RNA replication that should be useful for both basic research and applied studies.

This study investigated the monthly variation of water quality in the Amman-Zarqa and Balqa regions in Jordan in terms of pH, ammonium, nitrate and conductivity. During 2004 there was no monthly variation in water quality for most of the tested parameters. All readings were above the accepted range except for pH, indicating that land use does have an impact on water quality irrespective of urban, industrial or agricultural usage. The water quality remained for the most part below the maximum levels for drinking standards in Jordan, but these standards are often below the WHO recommendations. The pH was found to fluctuate through the year. Nitrate levels were highly seasonal in irrigated lands but remained stable over basin covered by other land uses. Ammonium levels were high in areas of urbanisation and intensive animal husbandry as a consequence of effluent infiltration, peaking during the wet season due to increased infiltration. These results indicate that, over an annual cycle, the variation in water quality remains constant;however the continued drawdown of the aquifer system will inevitably lead to deterioration in the parameters investigated.

It is reasonably well established that the Earth has substantially cooled from the Archean to the pre-sent and hence the sites, rates and pro- cesses of crust formation must have changed through geo-logic time. Archean and Proterozoic granitic rocks are the principal record of such changes. Massif-type charnockites in the Eastern Ghats granulite belt, India, of Archean and Proterozoic ages mirror the changing conditions and/or processes of continental crust for- mation. Though both can be explained by dehydration melting of mafic rocks, the conditions differ. Potasium and rubidium rich Proterozoic charnockites have significant negative Eu ano- maly indicating melting at shallow depths in the stability field of plagioclase. In contrast, sodium and strontium rich Archean charnockites with less LREE enrichment and less depletion in Eu indicate melting at greater depths in the stability field of garnet or amphibole.

Electric and magnetic fields in time and frequency domain due to return stroke-lateral corona (RS-LC) system and re- cently discovered red sprites have been calculated. It has been found that the electric and magnetic fields due to return stroke and lateral corona system radiate in the very low frequency (VLF) region while due to sprites radiate in the ex- tremely low frequency (ELF) range. A comparison has been made between the radiations emitted due to RS-LC system and sprites in ELF (0 - 200 Hz) region. It has been found that the electric field i.e. radiation power generated due to sprites dominates in the ELF range and thus it is concluded that the red sprites as compared to the RS-LC system are the prominent source for the excitation of Schumann resonances in the earth-ionosphere waveguide.
