Beam Induced Fluorescence Monitor Due to the high beam power expected for FAIR, novel methods for non-intersecting beam diagnostics for the High Energy Beam Transport Lines must be considered. We investigate the detection of fluorescence photons from the excited states of the residual gas N2 with a Beam Induced Fluorescence (BIF) Monitor [1]. This method was successfully applied for high curren...
Using a multiple alignment of 175 cytochrome P450 (CYP) family 2 sequences, 20 conserved sequence motifs (CSMs) were identified with the program PCPMer. Functional importance of the CSM in CYP2B enzymes was assessed from available data on site-directed mutants and genetic variants. These analyses suggested an important role of the CSM 8, which corresponds to(187)RFDYKD(192) in CYP2B4. Further a...
BACKGROUND AND PURPOSE Carotid intima-media thickness (IMT) progression rates are increasingly used as an intermediate outcome for vascular risk. The carotid bifurcation (BIF) and internal carotid artery (ICA) are predilection sites for atherosclerosis. IMT measures from these sites may be a better estimate of atherosclerosis than common carotid artery (CCA) IMT. The study aim was to evaluate s...
Non-intercepting Beam Induced Fluorescence (BIF) monitors measure transversal beam profiles by observation of fluorescence light originating from excited residual gas molecules. Thus they are an alternative to conventional intercepting devices. Single photon counting is performed using an image intensified digital CCD camera. We investigated the BIF process in the energy range of 7.7 keV/u to 7...
Monodisperse orthorhombic-phase BiF(3) nanocrystals with various shapes were prepared easily by a novel solvent extraction approach using an acid-base-coupled extractant. More importantly, the extractant used in this route can be recycled after synthesis. Our results show great promise for further extending the method to the preparation of other metal-fluoride nanoparticles.
Background Body experience is an important facet of psychosocial functioning and health. However, to date no test exists measure body in adults with mild intellectual disability borderline (MID-BIF). We therefore adapted the Experience Questionnaire (BEQ) this group, resulting BEQ-mb, evaluated its usability, comprehensibility, reliability.Method The BEQ-mb was developed five stages: concept de...
Twenty-four composite samples of the fine-grained matrix glacial diamictites deposited from Mesoarchaean to Palaeozoic have been analysed for their silicon isotope composition and used establish, first time, long-term secular Si record compositional evolution upper continental crust (UCC). Diamictites with Archaean Palaeoproterozoic Nd model ages show greater heterogeneity than those younger (i...
Banded iron formations (BIFs) are enigmatic chemical sedimentary rocks that chronicle the geochemical and microbial cycling of carbon in Precambrian. However, formation pathways Fe carbonate, namely siderite, remain disputed. Here, we provide photomicrographs, Fe, C O isotope organic whole rock from ~2.52 Ga Dagushan BIF Anshan area, China, to discuss origin siderite. There small magnetite grai...
In this study, in vitro and vivo genotoxic effects of Bifenthrin (BIF), an important insecticide used agricultural production, storage processing, were investigated. The genoprotective properties purslane (Portulaca oleracea L.) against the BIF also determined by using methanol (POmet) extract plant. experiments performed with somatic mutation recombination test (SMART) Drosophila melanogaster....
