Inhibition of quorum sensing virulente factors of Pseudomonas aeruginosa PAO1 by Ferulago macedonica and Echinophora sibthorpiana extracts and essential oils

This study was conducted to analyse extracts and essential oils of Ferulago macedonica and Echinophora sibthorpiana (Apiaceae) for anti–quorum sensing potential using Pseudomonas aerugonisa PAO1 as biomonitoring system. Anti–quorum sensing screening was carried out by tree different tests which showed that examined samples possessed significant effects in suppressing of some virulent determinants of PAO1. The essential oils of F. macedonica and E. sibthorpiana aerial parts reduced the growth and modified the appearance of P. aeruginosa colonies and flagella to a large extent in twitching and motility assay. In the presence of essential oil of E. sibthorpiana, diameter of the colony was 6.67 mm, the flagella were absent and the color of the colony was changed from green to white. In anti–biofilm assay, the inhibitory activity of E. sibthorpiana was more notable than of F. macedonica. Applied colorimetric test revealed that examined samples strongly reduced the production of pigment pyocyanin where the highest inhibition of its synthesis showed F. macedonica oil (5.22%), followed by E. sibthorpiana oil (10.69%), which was singnificantly bigger potential in comparison to used antibiotics (141.55%)

Collision processes in low-temperature hydrogen plasmas

Collision processes among the constituents of low-temperature hydrogen plasmas (e, H, H"+, H"-, H_2, H_2"+, H_3"+) play a key role in technical plasma applications as well as in the boundary regions of magnetically confined fusion plasmas. In this work a review of the current knowledge on their cross sections is presented. Collision processes of electronically and vibrationally excited species are also included in the present review. The energy range in which these processes are considered extends from thermal energies to several hundreds electronvolts (and to the keV region for some heavy-particle collision processes). The available experimental and theoretical cross section information is critically assessed and presented in form of analytic fit functions, convenient for use in plasma applications.

Collision processes of hydrocarbon species in hydrogen plasmas. II: The ethane and propane families

Cross sections and rate coefficients are provided for collision processes of electrons and protons with C_xH_y and C_xH_y"+ (x = 2, 3; 1 #<=# y #<=# 2x + 2) hydrocarbon species in a wide range of collision energies and plasma (gas) temperatures. The considered processes include: electron-impact ionization and dissociation of C_xH_y, dissociative excitation, ionization and recombination of C_xH_y"+ with electrons, and both charge transfer and atom exchange in proton channels are considered separately. Information is also provided for the energies of each individual reaction channel. The cross sections and rate coefficients are presented in compact analytic forms.

Collision processes of hydrocarbon species in hydrogen plasmas. Pt. 3. The Silane-family

Cross sections are provided for most important collision processes of the Silicon-Hydrides from the ''Silane-family'': SiH_y (y = 1 - 4) molecules and their ions SiH_y"+, with (plasma) electrons and protons. The processes include: electron impact ionization and dissociation of SiH_y, dissociative excitation, ionization and recombination of SiH_y"+ ions with electrons, and charge - and atom - exchange in proton collisions with SiH_y. All important channels of dissociative processes are considered. Information is also provided on the energetics (reactants/products energy loss / gain) of each individual reaction channel. Total and partial cross sections are presented in compact analytic forms. The critical assessment of data, derivation of new data and presentation of results follow closely the concepts of the recently published related databases for Carbon-Hydrides, namely for the Methane family, and for the Ethane- and the Propane families, respectively.

Supplementary material from "Teaching open and reproducible scholarship: a critical review of the evidence base for current pedagogical methods and their outcomes"

In recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergraduate and postgraduate research training. Specifically, a critical overview of the literature which investigates how integrating open and reproducible science may influence student outcomes is needed. In this paper, we provide the first critical review of literature surrounding the integration of open and reproducible scholarship into teaching and learning and its associated outcomes in students. Our review highlighted how embedding open and reproducible scholarship appears to be associated with (i) students' scientific literacies (i.e. students’ understanding of open research, consumption of science and the development of transferable skills); (ii) student engagement (i.e. motivation and engagement with learning, collaboration and engagement in open research) and (iii) students' attitudes towards science (i.e. trust in science and confidence in research findings). However, our review also identified a need for more robust and rigorous methods within pedagogical research, including more interventional and experimental evaluations of teaching practice. We discuss implications for teaching and learning scholarship
