The genes encoding the enzymes of IMP biosynthesis in Bacillus subtilis constitute the pur operon, whereas the genes encoding GMP biosynthetic enzymes, guaA (GMP synthetase) and guaB (IMP dehydrogenase), and the purA gene encoding adenylosuccinate (sAMP) synthetase all occur as single units. The purB gene encodes an enzyme involved in both IMP and AMP biosynthesis and is located in the pur oper...

The studies were carried out to isolate the mango quick decline fungi from mango bark beetle, Hypocryphalus mangiferae S. collected from mango orchards of Nawab pur, Lutfabad and Faiz pur bhatian, Multan, Pakistan. Different life stages of H. mangiferae were collected from diseased mango trees and fungal isolations were carried out from each stage as well as from different body parts (head, tho...

The effects of adding an extra layer within a sandwich panel and two different core types in top and bottom cores on low velocity impact loadings are studied experimentally in this paper. The panel includes polymer composite laminated sheets for faces and the internal laminated sheet called extra layer sheet, and two types of crushable foams are selected as the core material. Low velocity impac...

[JRB] The first part of Bloedel's target article reviews evidence for the organization of the cerebellum into sagittal zones and suggests that the functioning of the cerebellum is through sagittally organized units of cells. Bloedel proposes that Pur

This study identified the role of milling and parboiling on arsenic (As) content its species in large numbers rice samples. Total As contents were 108 ± 33 μg/kg polished grains (PR), 159 46 unpolished (UR), 145 42 parboiled (PPR) 44 (PUR). The percentages inorganic (iAs) 66% 8% PR from 72% to 77% other grain categories. polishing process reduced grains, removing outer part UR with high amount ...

Epoxy resins are widely used in composite materials for aircraft applications. However, they difficult to recycle, thus posing an increasing challenge the aviation sector. By contrast, polyurethane (PUR) can be easily chemically recycled by solvolysis, but structural parts made of carbon fibre-reinforced polyurethanes (CF-PURs) currently not use This is due a lack knowledge about properties CF-...
