Success Pattern Finding With Regards To Textual Content Exploration

Various algorithms such as Object Rank and PageRank, the latter created by Larry Page and used in Google Search Engine, were highly expensive as they required a PageRank style iterative computation over the full graph. BinRank, a hybrid algorithm proposed uses an index of pre computed results for some/or all keywords being used by the user Dynamic authority based online keyword search algorithms, such as Object rank and personalized page rank leverage semantic link in formation to provide high quality, high  recall search in databases and the web Conceptually, these  algorithms require a query time  page rank style iterative computation over the full graph. This computation is too  expensive for large graphs and not feasible at query time . Alternatively, building an index of pre computed results for some  or all keywords involves very expensive processing. We introduce  BinRank,a system that approximates ObjectRank results by utilizing a hybrid approach inspired by materialize d views in traditional query processing. The issue addressed in this paper is would like to provide an approach which intends to provide an approximation to BinRank by integrating it with Hubrank and parallelize i.e execute the activities simultaneously to reduce query execution time and also increase the relevance of the results. Bin Rank system which  approximates Object Rank results by utilizing a hybrid approach inspired by materialized views in traditional query  processing

Impact of diesel vehicular emissions on ambient black carbon concentration at an urban location in India

Vehicular emissions in the urban areas are known to contribute significantly to aerosol black carbon (BC) loading to the atmosphere. Quantification of BC emissions is important from the climate research point of view, as the BC aerosols strongly absorb solar radiation. A case study has been carried out in an urban area, Hyderabad, to assess the impact of emissions associated with truck transport on ambient BC concentration. The study was carried out during the recent nationwide truck strike of April 2003. The results indicate a significant reduction in the BC loading associated with withdrawal of the trucks. The decrease was gradual, while the recovery was almost immediate

REMP software to introduce a screening REstriction site in site-directed Mutagenesis Primer

Insertion of silent mutations allowing for restriction site modification aids in the screening of successful mutants during site directed mutagenesis. Introducing a new restriction site requires the analysis of degenerate sequences within mutant primer. As the total number of degenerate codons increases, the analysis becomes increasingly laborious, time-consuming and prone to errors. Towards this, a software named as ‘REMP’ (for REstriction site in Mutant Primer) was developed and described here. From the input sequence, REMP instantaneously generates degenerate sequences having restriction sites that are 6–8 base pairs in length. The output sequences are arranged based on the number of bases changed compared to the input sequence. REMP software can be installed and run as a stand-alone program on different operating systems. Any user of REMP can edit the list of restriction sites to be considered by the software, without a need for writing a computer code or knowing a program language. © 202

Downregulation of RWA genes in hybrid aspen affects xylan acetylation and wood saccharification

High acetylation of angiosperm wood hinders its conversion to sugars by glycoside hydrolases, subsequent ethanol fermentation and (hence) its use for biofuel production. We studied the REDUCED WALL ACETYLATION (RWA) gene family of the hardwood model Populus to evaluate its potential for improving saccharification. The family has two clades, AB and CD, containing two genes each. All four genes are expressed in developing wood but only RWA-A and -B are activated by master switches of the secondary cell wall PtNST1 and PtMYB21. Histochemical analysis of promoter:: GUS lines in hybrid aspen (Populus tremula x tremuloides) showed activation of RWA-A and -B promoters in the secondary wall formation zone, while RWA-C and -D promoter activity was diffuse. Ectopic downregulation of either clade reduced wood xylan and xyloglucan acetylation. Suppressing both clades simultaneously using the wood-specific promoter reduced wood acetylation by 25% and decreased acetylation at position 2 of Xylp in the dimethyl sulfoxide-extracted xylan. This did not affect plant growth but decreased xylose and increased glucose contents in the noncellulosic monosaccharide fraction, and increased glucose and xylose yields of wood enzymatic hydrolysis without pretreatment. Both RWA clades regulate wood xylan acetylation in aspen and are promising targets to improve wood saccharification.Peer reviewe

RIGHT NUCLEUS IN GENERALIZED RIGHT ALTERNATIVE RINGS

Some properties of the right nucleus in generalized right alternative rings have been presented in this paper. In a generalized right alternative ring R which is finitely generated or free of locally nilpotent ideals, the right nucleus Nr equals the center C. Also, if R is prime and Nr  C, then the associator ideal of R is locally nilpotent. Seong Nam [5] studied the properties of the right nucleus in right alternative algebra. He showed that if R is a prime right alternative algebra of char. ≠ 2 and Right nucleus Nr is not equal to the center C, then the associator ideal of R is locally nilpotent. But the problem arises when it come with the study of generalized right alternative ring as the ring dose not absorb the right alternative identity. In this paper we consider our ring to be generalized right alternative ring and try to prove the results of Seong Nam [5]. At the end of this paper we give an example to show that the generalized right alternative ring is not right alternative

Effect of aerosols on erythemal ultraviolet radiation

56-61The present study reports, for the first time, on seasonal variation of UV erythema (UVery) and its relation with aerosols over a typical urban environment of Hyderabad, India during 2001-2003. Drastic reduction in UV intensities has been observed during periods of high aerosol loading. Comparison of UVery intensities with aerosol optical depth on normal summer day and a day after heavy rainfall suggests ~45% increase in UVery intensities because of scavenging of particles in the atmosphere. Total columnar ozone showed negative correlation with UVery. The results are discussed in the paper

Parametric finite element analyses of geocellsupported embankments

This paper presents the results from parametric finite element analyses of geocell-supported embankments constructed on weak foundation soils. A composite model is used to numerically simulate the improvement in the strength and stiffness of the soil as a result of geocell confinement. The shear strength of the geocell-encased soil is obtained as a function of the additional confining pressure due to the geocell encasement considering it as a thin cylinder subjected to internal pressure. The stiffness of the geocell-encased soil is obtained from the stiffness of the unreinforced soil and the tensile modulus of the geocell material using an empirical equation. The validity of the model is verified by simulating the laboratory experiments on model geocell-supported embankments. Parametric finite element analyses of the geocell-supported embankments are carried out by varying the dimensions of the geocell layer, the tensile strength of the material used for fabricating the geocell layer, the properties of the infill soil, and the depth of the foundation layer. Some important guidelines for selecting the geocell reinforcement to support embankments on weak foundation soils are established through these numerical studies
