Insulation systems must have a number of special properties when used on construction sites located in the zone significant negative temperatures, wind load, and associated air filtration through building struc-tures, under influence coastal environment that forms salts tech-nical facilities with production transportation petro-leum products. Firstly, high operational stability, including influ...

Bangladesh is one of the largest exporters of jute which is commonly processed with mineral Jute Batching Oil (JBO). JBO-processed jute products (especially food grade packaging item) have poor acceptability worldwide mainly due to their unpleasant odor, texture and the possible presence of carcinogenic compounds Foreign market has demanded replacement of mineral JBO and it is high time not to ...

The mass concentration, chemical composition and sources of quasi-ultrafine (quasi-UFP, PM0.25), accumulation (PM0.25−2.5) and coarse mode (PM2.5−10) particles were determined in indoor and outdoor air at 39 schools in Barcelona (Spain). Quasi-UFP mass concentrations measured (25.6 μg m−3 outdoors, 23.4 μg m−3 indoors) are significantly higher than those reported in other studies, and character...

Synergistic relations between organic molecules and mineral precursors regulate biogenic mineralization. Given the remarkable material properties of the egg shell as a biogenic ceramic, it serves as an important model to elucidate biomineral growth. With established roles of complex anionic biopolymers and a heterogeneous organic scaffold in egg shell mineralization, the present study explores ...

If life ever existed, or still exists, on Mars, its record is likely to be found in minerals formed by, or in association with, microorganisms. An important concept regarding interpretation of the mineralogical record for evidence of life is that, broadly defined, life perturbs disequilibria that arise due to kinetic barriers and can impart unexpected structure to an abiotic system. Many featur...
