Protonated 1,4-benzodiazepines dissociate in the gas phase by the common pathway of CO elimination and by unique pathways dictated by the substituents; the latter typically differentiate one benzodiazepine from another. Protonated 3-dihydro-5-phenyl-1,4-benzodiazepin-2-one, the base diazepam devoid of substituents, dissociates by eliminating CO, HNCO, benzene, and benzonitrile. Mechanisms of th...

Image Compression is the application of Data Compression on digital image. The techniques used for the image compression are broadly divided into lossy and lossless compression techniques. One of the lossless compression techniques is Huffman encoding. In this paper, the new method MH Encoding (Median Filter + Huffman Encoding) is used to compress the images. Here the images are preprocessed us...

1002 several occasions as well. For instance, the unadorned wings of the most famous species in the genus, D. melanogaster, derive from a distant spotted ancestor. Prud’homme et al. took advantage of this chequered history to study the genetic basis for convergence. To validate their approach, they examined two spotted species that derive from the same spotted ancestor and whose spots would the...

583 syndrome: behavioural changes, decreased muscle strength, heart defects, annular pancreas, aganglionic megacolon, immune defects and placental vascular abnormalities. So Arron et al. looked for genes in the DSCR that could regulate NFATc. They identified DYRK1A, which encodes a kinase, and DSCR1, which encodes a known inhibitor of calcineurin. The DYRK1A and DSCR1 proteins acted synergistic...

Biodiesel is an alternative fuel derived from fatty acids in vegetable oils or animal fats. Because it contains almost no sulphur, it burns more cleanly than conventional diesel. However, the chemical reaction that breaks down the fatty acids into fuel relies on an aqueous alkali catalyst such as sodium hydroxide, making the product difficult to separate from the reaction mixture. Robert S. Wat...

iour’ to variation in the expression patterns of the receptors for two related signalling molecules, oxytocin and arginine vasopressin (vasopressin for short). These molecules are released in the brain after sex, and are also involved in other reproductionrelated behaviours and in unrelated functions such as water retention and stress. Notably, the vasopressin 1a receptor (V1aR) is expressed in...
