A method for characterizing pigmented bacteria based on the numerical analysis of their carotenoid absorption spectra was examined. To achieve this, some non-phototrophic pigmented bacteria that were isolated from various environments and closely related types of species were used. Bacterial carotenoid pigments were extracted with an acetone:methanol (7:2) mixture and the absorption spectra wer...

cry genes encoding cry proteins toxic to lepidoptera, coleoptera and diptera species were studied in thirty seven b. thuringiensis strains isolated from twelve naturally infested heliothis armigera larvae. to further confirm the isolates, two groups of species-indicative biochemical tests were applied while discriminative biochemical tests being employed to figure out the repetitive strains. a ...

Piezocone penetration tests with dissipation phases are particularly useful for geotechnical site characterization. They also provide three independent readings with depth from a single sounding as well as time-rate information. In past investigations, only silty sands with specific silt content have been tested and complete sets of tests have not been conducted to evaluate the influence of dif...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...

This article contains information related to a recent study "Performance-based interpretation of in-plane cyclic tests on RC frames with strong masonry infills" (Morandi et al., 2017 [1]). Motivated by the necessity to improve the knowledge of the in-plane seismic response of rigid strong masonry infills, a wide experimental campaign based on in-plane cyclic tests on full-scale RC infilled fram...

Minitek (BBL Microbiology Systems, Cockeysville, Md.) substrate disks were evaluated as alternatives to conventional tests for the characterization of Bacillus species. Results were compared for 10 reference isolates and 87 isolates from food sources. The overall agreement of results between the Minitek and conventional tests was 92% for reference strains and 86% for food isolates.

The mechanical behaviour of laminated glass is strongly affected by the polymeric interlayer placed between layers. In general, this a viscoelastic material, and therefore it may experience creep stress relaxation when subjected for an extended period to constant or strain respectively. study, seven different commercial materials (EVALAM, EVASAFE, PVB BG-R20, Saflex DG-41, ES, SentryGlas, TPU) ...
