Many-multiplet (MM) method [1] applied to Keck/HIRES quasar absorption spectra gives a shift in the value of the fine-structure constant of ∆α/α = (−5.4±1.2)×10−6 [2]. Theoretical models of the fundamental physical interactions predict in this case a shift in the protonto-electron mass ratio (μ = mp/me) of about ∆μ/μ ∼ −2× 10−4. We used VLT/UVES high-resolution observations of molecular hydroge...

A wide variety of chemicals are shipped in bulk world-wide, raising concerns regarding the ecological and human health risks of spills of hazardous materials. A screening analysis was performed, using the chemical spill model CHEMMAP to estimate the expected fate and concentrations of chemical in water resulting from a spill into a large estuary and the potential ecological hazards to aquatic b...

The structure of Mth677, a hypothetical protein from Methanobacterium thermoautotrophicum (Mth), has been determined by using heteronuclear nuclear magnetic resonance (NMR) methods on a double-labeled N-C sample. Mth677 adopts a novel + fold, consisting of two -helices (one N terminal and one C terminal) packed on the same side of a central -hairpin. This structure is likely shared by its three...

Every user appreciates the security of their data irrespective of its sensitivity. At the same time, user does not want to be held up with the legacy systems, which may be strongly secured but not with fantasy. Network travelled many phases of its own such as internet, intranet, wireless network, sensor network, Ad-hoc network, Mobile network, Blue-tooth, Cloud and IoT, the most popular techniq...

HI1506 is a 128-residue hypothetical protein of unknown function from Haemophilus influenzae. It was originally annotated as a shorter 85-residue protein, but a more detailed sequence analysis conducted in our laboratory revealed that the full-length protein has an additional 43 residues on the C terminus, corresponding with a region initially ascribed to HI1507. As part of a larger effort to u...
