To improve biofilter performance, the microbial community of a biofilter must be clearly defined. In this study, the performance of a lab-scale polyurethane biofilter for treating waste gas with low loads of nitrobenzene (NB) (< 20 g m-3 h-1) was investigated when using different empty bed residence times (EBRT) (64, 55.4 and 34 s, respectively). In addition, the variations of the bacterial com...

We investigate the gravitational instability of galactic discs, treating stars and cold interstellar gas as two distinct components, and taking into account the phenomenology of turbulence in the interstellar medium (ISM), i.e. the Larson-type scaling relations observed in the molecular and atomic gas. Besides deriving general properties of such systems, we analyse a large sample of galaxies fr...

This study evaluated the efficacy of polyvinyl alcohol (PVA)‐coated powdered activated carbon particles as a biofiltration medium. This material exhibited excellent properties as a biofiltration medium with a water holding capacity of 1.39 g H2O/g‐dry PVA; wet porosity of 0.53; and significantly lower pressure drop than that of commonly reported biofilter media such as compost. Bench‐scale biof...

308nm xenon-chloride excimer laser, a novel mode of phototherapy, is an ultraviolet b radiation system consisting of a noble gas and halide. the aim of this systematic review was to investigate the literature and summarize all the experiments, clinical trials and case reports on 308-nm excimer laser in dermatological disorders. 308-nm excimer laser has currently a verified efficacy in treating ...

The very low basicity and nucleophilicity of the phosphorus donor in phosphinines can be drastically increased by introducing strongly σ-donating Me3Si substituents to aromatic heterocycle. highest gas-phase was found for 2,3,5,6-tetrakis(trimethylsilyl)phosphinine, which is even more basic gas phase than pyridine. This finding led first quantitative synthesis a phosphinine selenide treating re...

Fine and colleagues’ article in this issue (1) adds an interesting variation on the “sore throat question.” Whether to treat or test patients with sore throat continues to generate differing opinions. International guidelines suggest 3 strategies: neither test nor treat anyone, test patients with a substantial probability of group A streptococcal (GAS) pharyngitis and treat those who test posit...
