Different modified atmosphere conditions with various CO2 concentrations on microbial load (psychrophile, mesophile aerobic and anaerobic bacteria) and physico-chemical properties of barramundi (Lates calcarifer Bloch) fillets stored at 8°C were compared to determine the best packaging conditions. The gas conditions evaluated were 100% CO2 (M1), 75% CO2/25% N2 (M2), 50% CO2/50% N2 (M3), 25% CO...
A multiple-unit floating drug delivery system based on gas formation technique was developed, in order to prolong the gastric residence time and to increase the overall bioavailability of the dosage form. The floating bead formulations were prepared by dispersing nevirapine together with calcium carbonate in a mixture of sodium alginate and hydroxypropyl methylcellulose solution and then drippi...
We present our preliminary BIMA CO(1-0) images of II Zw 96 which show huge molecular gas concentrations outside the merging disks. The dominant extra-disk CO concentrations in II Zw 96 correspond to the two star-forming “knots” hidden by dust, whereas the others are associated with the two spiral disks. The unique huge CO concentrations, > ∼5 kpc away from the merging nuclei, account for > ∼50%...
How galaxies form from, and are fueled by, gas from the intergalactic medium (IGM) remains one of the major unsolved problems in galaxy formation. While the classical Cold Dark Matter paradigm posits galaxies forming from cooling virialized gas, recent theory and numerical simulations have highlighted the importance of cold accretion flows—relatively cool (T ∼ few × 104 K) unshocked gas streami...
Post-starburst galaxies, or E+A galaxies, are characterized by optical spectra showing strong Balmer absorption lines, indicating a young stellar population, and little or no emission lines, implying no active star formation. These galaxies are interpreted as a transitional population between star-forming, disc-dominated galaxies and spheroidal quiescent, non-star-forming galaxies. Here, we pre...
We report on single-dish radio CO observations towards the inter-galactic medium (IGM) of the Stephan’s Quintet (hereafter SQ) compact group of galaxies. Extremely bright mid-IR H2 rotational line emission (L(H2) ≈ 1035 W) from warm (102−3 K) molecular gas has been detected by the Spitzer satellite in the kpcscale shock created by a collision between a galaxy, NGC 7318b, and NGC 7319’s tidal ar...
The largest galaxies in the universe reside in galaxy clusters. Using sensitive observations of carbon monoxide, we show that the Spiderweb galaxy-a massive galaxy in a distant protocluster-is forming from a large reservoir of molecular gas. Most of this molecular gas lies between the protocluster galaxies and has low velocity dispersion, indicating that it is part of an enriched intergalactic ...
It has become increasingly apparent that Bacillus cereus can cause a severe and devastating form of endophthalmitis following penetrating trauma by a metallic object. B. cereus is an uncommon aetiological agent in non-clostridial gas-forming infections. The patient studied in this single case report showed evidence of intraocular gas mimicking gas gangrene infection. The physiology of non-clost...
