We experimentally investigate an optical clock based on Yb (I = 1/2) atoms confined in an optical lattice. We have evaluated all known frequency shifts to the clock transition, including a densitydependent collision shift, with a fractional uncertainty of 3.4 × 10, limited principally by uncertainty in the blackbody radiation Stark shift. We measured the absolute clock transition frequency rela...

The methane and digestate production from biowaste (BW, 95% food waste 5% garden based on fresh mass) grease trap sludge (GTS) co-digestion at the Grossache-Nord WWTP (Austria) as a basis for cost-benefit analysis was determined using two approaches: first one to determine specific yields (SMY) total solids (TS) removals (%) of used substrates in biomethane potential (BMP) tests. In second, ful...

Recently, putative viral agents responsible for human non-A to E hepatitis have been independently reported by two groups of investigators and designated GB virus C (GBV-C) and hepatitis G virus (HGV), respectively. The entire nucleotide sequences were determined for two viral genomes isolated from Japanese blood donors with GBV-C RNA. One of them (GT230) had a total genomic length of 9390 nucl...

BACKGROUND In this experiment, abdominal cavity of 518 Iranian Sistani cattle and 498 Brahman cattle were inspected for the presence of Setaria spp. from April 2012 - May 2013. METHODS The species were determined by microscopic examination of the morphological characteristics of the anterior and posterior parts of the parasites and authentic guidelines. RESULTS The overall prevalence of Set...

The aim of this study was to investigate the feasibility of using layer-by-layer polymer coated gold nanoparticles (AuNP) as a carrier for topical iontophoretic delivery of imatinib mesylate (IM). AuNP were prepared by the Turkevich method and were stabilized and functionalized using polyvinylpyrrolidone and polyethylene imine. The functionalized AuNP were then sequentially coated with anionic ...

suppose $t$ and $s$ are moore-penrose invertible operators betweenhilbert c*-module. some necessary and sufficient conditions are given for thereverse order law $(ts)^{ dag} =s^{ dag} t^{ dag}$ to hold.in particular, we show that the equality holds if and only if $ran(t^{*}ts) subseteq ran(s)$ and $ran(ss^{*}t^{*}) subseteq ran(t^{*}),$ which was studied first by greville [{it siam rev. 8 (1966...
