Research has suggested the existence of a pathological dissociative taxon. However, relatively little is known about this taxon. This study examined the 2-month retest stability of this taxon--together with other measures of dissociation and the Big Five--in a sample of 465 undergraduates. Contrary to expectation, taxon scores were only modestly stable and were substantially less stable than th...

The purpose of this study was to investigate the antimicrobial properties of a conventionalpoly methyl methacrylate (PMMA) modified with hydrothermally synthesised titaniumdioxide nanotubes (TNTs). Minimum inhibitory concentration (MIC), minimum bactericidalconcentration (MBC), and minimum fungicidal concentrations (MFC) for planktonic cellsof the TiO2 nanotubes solution against Lactobacillus a...

Motivation We have little understanding of how communities respond to varying magnitudes and rates environmental perturbations across temporal scales. BioDeepTime harmonizes assemblage time series presence abundance data help facilitate investigations community dynamics timescales the response natural anthropogenic stressors. includes terrestrial aquatic assemblages spatial grain extent from pr...

It is well known among phylogeneticists that adding an extra taxon (e.g. species) to a data set can alter the structure of the optimal phylogenetic tree in surprising ways. However, little is known about this "rogue taxon" effect. In this paper we characterize the behavior of balanced minimum evolution (BME) phylogenetics on data sets of this type using tools from polyhedral geometry. First we ...

Bacterial infections cause 300 million cases of severe illness each year worldwide. Rapidly accelerating drug resistance further exacerbates this threat to human health. While dispersed (planktonic) bacteria represent a therapeutic challenge, bacterial biofilms present major hurdles for both diagnosis and treatment. Nanoparticles have emerged recently as tools for fighting drug-resistant plankt...

The present paper provides results of a study on heterotrophic bacteria occurrence and quantity in the biofilm and subsurface water of lake Jeziorak Maty. Degradation of several polycyclic aromatic hydrocarbons (PAH's) (anthracene, naphthalene) by neustonic and planktonic bacteria have been examined. It has been discovered that some aromatic hydrocarbons were better decomposed by neustonic bact...

A study on the occurrence and chitinolytic activity of planktonic, benthic and epiphytic bacteria was carried out in the Moty Bay of Lake Jeziorak near Ilawa. The greatest number of chitinolytic bacteria occurred on macrophytes. In terms of percentages, the chitinolytic bacteria share among heterotrophic bacteria was much greater in epiphytic and planktonic bacteria than in benthic ones. When c...

Abstract Globuligerina glinskikhae nov. sp. Gradstein & Waskowska and waskowskae are new species of Jurassic planktonic foraminifera from the Middle Dagestan Poland. G. with its remarkable ‘protoglobigerine’ test may be an early evolutionary offshoot oxfordiana (Grigelis). It index taxon for upper Bajocian through Bathonian strata in Eastern Europe Southwest Asia, might recognizable also th...
