TL;DR: Six bacterial strains were isolated from a damaged medieval wall painting by a polyphasic approach, including analysis of respiratory isoprenoid quinones, polar lipids, fatty acids, polyamines, cell wall diamino acids and sugars from whole cell hydrolysates, and partial 16S rDNA sequence analysis.

TL;DR: The first half of 2015, when Psychological Science gave authors the opportunity to signal open data and materials if they qualified for badges that accompanied published articles, showed an increase of more than an order of magnitude from baseline as discussed by the authors.
Abstract: Beginning January 2014, Psychological Science gave authors the opportunity to signal open data and materials if they qualified for badges that accompanied published articles. Before badges, less than 3% of Psychological Science articles reported open data. After badges, 23% reported open data, with an accelerating trend; 39% reported open data in the first half of 2015, an increase of more than an order of magnitude from baseline. There was no change over time in the low rates of data sharing among comparison journals. Moreover, reporting openness does not guarantee openness. When badges were earned, reportedly available data were more likely to be actually available, correct, usable, and complete than when badges were not earned. Open materials also increased to a weaker degree, and there was more variability among comparison journals. Badges are simple, effective signals to promote open practices and improve preservation of data and materials by using independent repositories.

RCTs with Introduction a follow-up of <6 months and with a substantial number of patients in urinary retention preoperatively were For decades TURP was the undisputed gold standard of therapy for patients with LUTS due to BPH; however, excluded. within the past 10 years this role has increasingly been challenged by the development of medical (5a reductase The current morbidity of TURP inhibitors, a1-receptor blockers) and less invasive interventional alternatives [1–8].

TL;DR: In this paper, the role of magnetized matter circulation between the gaseous disk and the surrounding galactic halo is investigated using a 3D MHD code with adaptive mesh refinement developed for this purpose.
Abstract: In star forming disk galaxies, matter circulation between stars and the interstellar gas, and, in particular the energy input by random and clustered supernova explosions, determine the dynamical and chemical evolution of the ISM, and hence of the galaxy as a whole. Using a 3D MHD code with adaptive mesh refinement developed for this purpose, we have investigated the role of magnetized matter circulation between the gaseous disk and the surrounding galactic halo. Special emphasis has been put on the effect of the magnetic field with respect to the volume and mass fractions of the different ISM “phases”, the relative importance of ram, thermal and magnetic pressures, and whether the field can prevent matter transport from the disk into the halo. The simulations were performed on a grid with an area of 1 kpc2 , centered on the solar circle, extending ± 10 kpc perpendicular to the galactic disk with a resolution as high as 1.25 pc. The simulations were run for a time scale of 400 Myr, sufficiently long to avoid memory effects of the initial setup, and to allow for a global dynamical equilibrium to be reached in case of a constant energy input rate. The main results of our simulations are: (i) The K gas is mainly concentrated in shock compressed layers, exhibiting the presence of high density clouds with sizes of a few parsecs and K. These structures are formed in regions where several large scale streams of convergent flow (driven by SNe) occur. They have lifetimes of a few free-fall times, are filamentary in structure, tend to be aligned with the local field and are associated with the highest field strengths; (ii) the magnetic field has a high variability and it is largely uncorrelated with the density , suggesting that it is driven by superalfvenic inertial motions; (iii) ram pressure controls the flow for K. For K magnetic pressure dominates, while the hot gas ( K) in contrast is controlled by the thermal pressure, since magnetic field lines are swept towards the dense compressed walls; (iv) up to of the mass in the disk is concentrated in the classical thermally unstable regime K with ∼ 65% of the warm neutral medium (WNM) mass enclosed in the K gas, consistent with recent observations; (v) the volume filling factors of the different temperature regimes depend sensitively on the existence of the duty cycle between the disk and halo, acting as a pressure release mechanism for the hot phase in the disk. We find that in general gas transport into the halo in 3D is not prevented by an initial disk parallel magnetic field, but only delayed initially, for as long as it is needed to punch holes into the thick magnetized gas disk. The mean volume filling factor of the hot phase in the disk is similar in HD and MHD (the latter with a total field strength of 4.4 μ G) runs, amounting to 17-21% for the Galactic supernova rate.

TL;DR: The effects of an accelerated UV-aging procedure on polystyrene microplastics, which are used in products such as skin cleaners and foams, are investigated and it is shown that aging led to significant surface oxidation and minor localized microcrack formation.
