On a whale shark, Rhincodon typus Smith, landed at Dakti Dahanu and Gungwada, Thane, Maharashtra

On 21st December 1999, a whale shark Rhincodon typus Smith (Male) got entangled in a nylon gill net (locally called wagrajal) at about 0400 hrs., at a depth of 40M. was landed at Dakti Dahanu & Gangwada

Bumper catch of sea bass, Lates calcarifer (Bloch, 1790) by gill netters in Mumbai waters

Lates calcarifer is commonly called as giant sea bass, sea perch or giant brackish water perch and in Maharastra, locally known as ‘Khajura’ (Waghmare and Sawant, 1994). Sea bass is considered as a valuable seafood delicacy with good demand in market. They are found in coastal waters, estuaries and lagoons usually at a depth of 40 m and mainly feed on fishes and crustaceans

Performance Evaluation of Vanilla, Residual, and Dense 2D U-Net Architectures for Skull Stripping of Augmented 3D T1-weighted MRI Head Scans

Skull Stripping is a requisite preliminary step in most diagnostic neuroimaging applications. Manual Skull Stripping methods define the gold standard for the domain but are time-consuming and challenging to integrate into processing pipelines with a high number of data samples. Automated methods are an active area of research for head MRI segmentation, especially deep learning methods such as U-Net architecture implementations. This study compares Vanilla, Residual, and Dense 2D U-Net architectures for Skull Stripping. The Dense 2D U-Net architecture outperforms the Vanilla and Residual counterparts by achieving an accuracy of 99.75% on a test dataset. It is observed that dense interconnections in a U-Net encourage feature reuse across layers of the architecture and allow for shallower models with the strengths of a deeper network.Comment: Research Article submitted to the 2nd International Conference on Biomedical Engineering Science and Technology: Roadway from Laboratory to Market, at the National Institute of Technology Raipur, Chhattisgarh, Indi

Involvement of a periplasmic protein kinase in DNA strand break repair and homologous recombination in Escherichia coli

The involvement of signal transduction in the repair of radiation-induced damage to DNA has been known in eukaryotes but remains understudied in bacteria. This article for the first time demonstrates a role for the periplasmic lipoprotein (YfgL) with protein kinase activity transducing a signal for DNA strand break repair in Escherichia coli. Purified YfgL protein showed physical as well as functional interaction with pyrroloquinoline-quinone in solution; the protein kinase activity of YfgL was strongly stimulated in the presence of pyrroloquinoline-quinone. Transgenic E. coli cells producing Deinococcus radiodurans pyrroloquinoline-quinone synthase showed nearly four log cycle improvement in UVC dark survival, 0-fold increases in gamma radiation resistance as compared with untransformed cells. Pyrroloquinoline-quinone enhanced the UV resistance of E. coli through the YfgL protein; required the active recombination repair proteins. The yfgL mutant showed higher sensitivity to UVC, mitomycin C, gamma radiation as compared with wild-type cells, showed a strong impairment in homologous DNA recombination. The mutant expressing an active YfgL in trans recovered the lost phenotypes to nearly wild-type levels. The results strongly suggest that the periplasmic phosphoquinolipoprotein kinase YfgL plays an important role in radiation-induced DNA strand break repair, homologous recombination in E. coli

Temperature induced biochemical changes and antioxidant activity in mature avocado (persea americana Mill.) fruit during storage

The present study was carried out to determine the effect of different storage temperatures (5oC, 9oC, 12oC and room temperature (26-32oC) on biochemical and antioxidant properties of two avocado accessions (CHES-HA-I/I and CHES-HA-VII/I). The result showed that titratable acidity, total soluble solids, and protein content decreased, while, fat content increased with the advancement of storage. The higher antioxidant activity was recorded in fruits stored at 9oC in both the accessions. At 5oC, fruits exhibited signs of chilling injury and lower antioxidant activity. Significantly higher phenolic content was found in fruits stored at room temperature. It was observed that both antioxidants and total phenolic content of avocado fruits increased irrespective of storage temperatures. It is, therefore, concluded that unlike other tropical fruits, as the ripening progressed, avocado fruits exhibited major change in biochemical and antioxidant activity

Trends in the landings of Sepia aculeata and Sepia prashadi at Mumbai, Maharashtra.

Cephalopod landing by trawlers in Mumbai consist of L.duvauceli, S.aculeata, S. inermis, S. pharaonis and Octopus spp. They are landed almost throughout the year at New Ferry Wharf and Sasoon Dock, Mumbai. A comparative study was made on the landings of S. aculeata and S. prashadi at New Ferry Wharf during September to December, 2001-2004

N-4-{Acetyl}-5-(4-fluorophenyl)-4,5-dihydro-1,3,4-thiadiazol-2-ylacetamide

The title molecule, C12H12FN3O2S, shows a short intramolecular SO contact of 2.682 (18) A˚ . The dihedral angle between the thiadiazole ring and the benzene ring is 86.82 (11). In the crystal, N—HO and C—HO hydrogen bonds generate an R2 1 (6) graph-set motif between adjacent molecules. Pairs of futher C—HO hydrogen bonds form inversion dimers with R2 2 (8) ring motifs. These combine to generate a three-dimensional network and stack the molecules along the b axis

Interaction Between The Broad-lined Type Ic Supernova 2012ap and Carriers of Diffuse Interstellar Bands

The diffuse interstellar bands (DIBs) are absorption features observed in optical and near-infrared spectra that are thought to be associated with carbon-rich polyatomic molecules in interstellar gas. However, because the central wavelengths of these bands do not correspond with electronic transitions of any known atomic or molecular species, their nature has remained uncertain since their discovery almost a century ago. Here we report on unusually strong DIBs in optical spectra of the broad-lined Type Ic supernova SN 2012ap that exhibit changes in equivalent width over short (~30 days) timescales. The 4428 and 6283 Angstrom DIB features get weaker with time, whereas the 5780 Angstrom feature shows a marginal increase. These nonuniform changes suggest that the supernova is interacting with a nearby source of the DIBs and that the DIB carriers possess high ionization potentials, such as small cations or charged fullerenes. We conclude that moderate-resolution spectra of supernovae with DIB absorptions obtained within weeks of outburst could reveal unique information about the mass-loss environment of their progenitor systems and provide new constraints on the properties of DIB carriers.Comment: 6 pages, 3 figures, accepted for publication in ApJ
