Determination of petroleum-degrading bacteria isolated from crude oil-contaminated soil in Turkey

In order to establish an experimental basis for bioremediation of soil  contaminated with crude oil, 33 strains of bacteria with hydrocarbon-degrading ability were isolated from the contaminated soil in Adana, Batman and Adiyaman, Turkey. The strains were identified as Pseudomons spp.,  Paucimonas lemoignei, Stenotrophomonas maltophilia, Eschericha spp.,  Enterobacter spp. Citrobacter koseri, Acinetobacter spp., Aeromonas caviae,  Sphingobacterium multivorum, Klebsiella pneumoniae. Pseudomons  aeruginosa, Pseudomonas putida biotype A, Citrobacter amalonaticus GC subgroup A and Acinetobacter genomospecies, respectively. The ability to utilize crude oil as carbon source for their growth was ascertained. These bacterial isolates obtained in this study have catabolic capabilities for the biodegradation of petroleum hydrocarbons. Further study under soil conditions may be necessary to determine biodegradation potential of bacterial mixture tested in contaminated soil.Key words: Soil, crude oil, soil pollution, bacteria, biodegradation

Compressed representation of a partially defined integer function over multiple arguments

In OLAP (OnLine Analitical Processing) data are analysed in an n-dimensional cube. The cube may be represented as a partially defined function over n arguments. Considering that often the function is not defined everywhere, we ask: is there a known way of representing the function or the points in which it is defined, in a more compact manner than the trivial one

Study of Vector Boson Scattering and Search for New Physics in Events with Two Same-Sign Leptons and Two Jets

A study of vector boson scattering in pp collisions at a center-of-mass energy of 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.4 fb(-1) collected with the CMS detector. Candidate events are selected with exactly two leptons of the same charge, two jets with large rapidity separation and high dijet mass, and moderate missing transverse energy. The signal region is expected to be dominated by electroweak same-sign W-boson pair production. The observation agrees with the standard model prediction. The observed significance is 2.0 standard deviations, where a significance of 3.1 standard deviations is expected based on the standard model. Cross section measurements for (WW +/-)-W-+/- and WZ processes in the fiducial region are reported. Bounds on the structure of quartic vector-boson interactions are given in the framework of dimension-eight effective field theory operators, as well as limits on the production of doubly charged Higgs bosons
