Pseudomonas stutzeri KC is an aquifer isolate capable of denitrification and cometabolic transformation of carbon tetrachloride (CT) under anoxic conditions. Capillary experiments established that strain KC is chemotactic toward nitrate. A model aquifer column was used to evaluate the effects of motility in the presence of groundwater flow, and a second column was used to isolate motility in th...

A nonparametric Bayesian approach to co-clustering ensembles is presented. Similar to clustering ensembles, coclustering ensembles combine various base co-clustering results to obtain a more robust consensus co-clustering. To avoid pre-specifying the number of co-clusters, we specify independent Dirichlet process priors for the row and column clusters. Thus, the numbers of rowand column-cluster...

Abstract—Image or document encryption is needed through egovernment data base. Really in this paper we introduce two matrices images, one is the public, and the second is the secret (original). The analyses of each matrix is achieved using the transformation of singular values decomposition. So each matrix is transformed or analyzed to three matrices say row orthogonal basis, column orthogonal ...

Nerve cells and spontaneous coordinated behavior first appeared near the base of animal evolution in the common ancestor of cnidarians and bilaterians. Experiments on the cnidarian Hydra have demonstrated that nerve cells are essential for this behavior, although nerve cells in Hydra are organized in a diffuse network and do not form ganglia. Here we show that the gap junction protein innexin-2...

Lisfranc fracture dislocations are an often misdiagnosed injury pattern, which if left unreduced can lead to signifi cant disability (1-5). The articulation between the bases of the 5 metatarsals, cuneiforms, and cuboid has been termed the Lisfranc joint (6, 7). Lisfranc joint represents a junction between the forefoot and the midfoot. Three functional columns make up the tarsometatarsal area, ...

Superiorly – Skull base Inferiorly – Greater cornu of hyoid and Submandibular gland fascia Laterally – Ascending ramus of mandible Medially – Superior constrictor muscle and pharyngobasilar fascia with tonsillar fossa Anteriorly – Interpterygoids and buccinators fascia, tail of Submandibular gland Posteriorly – Vertebral column, paravertebral muscles. Posterolaterally – Parotid fascia, posterio...

We have developed a method for predicting the common secondary structure of large RNA multiple alignments using only the information in the alignment. It uses a series of progressively more sensitive searches of the data in an iterative manner to discover regions of base pairing; the first pass examines the entire multiple alignment. The searching uses two methods to find base pairings. Mutual ...

frasnian - famennian boundary in the kal-e-sardar section (east of tabas, central iran) is investigated on the basis of conodonts. distribution of thirty-three species and subspecies in the stratigraphic column enables us to recognize a barren interval and five biozones; upper rhenana, upper part of upper rhenana - linguiformis, lower to middle triangularis, upper triangularis, lower crepida. b...
