Four aspartic acids, distributed in different putative membrane-spanning segments of the NH2-terminal domain of melibiose (mel) permease (D31 in helix I, D51 and D55 in helix II, and D120 in helix IV) were individually replaced by either Asn or Cys using site-directed mutagenesis. mel permease with either neutral residues at position 51, 55, or 120 or permease with a Cys in place of D31 does no...

I perioden fra 2008 til 2017 har en ny arbejdsform – innovation kaldet hverdagsrehabilitering spredt sig blandt danske kommuner. Vi viser, at udviklingen er et eksempel på, hvordan New Public Governance (NPG) strategier supplerer og i nogen grad erstatter Management (NPM) strategier, undersøger spredningsmønsteret med udgangspunkt hypoteser diffusion-of-innovations-litteraturen. finder en, forh...

Çalışmada, 31 Lactobacillus delbrueckii subsp. bulgaricus ve 34 Streptococcus thermophilus bakteri kültürlerinde, o-nitrofenil-beta-D-galaktosit (o-NPG) substrat olarak kullanılarak, β-galaktosidaz enzim spesifik aktiviteleri taranmıştır. L. suşları 0.186-6.500 U/mg arasında aktivite gösterirken, S. 0.172-5.064 göstermiştir. ZN541 (6.500 U/mg) Z1052 (5.064 suşlarının yüksek yeteneğine sahip old...

In the context of sparse recovery, it is known that most of existing regularizers such as `1 suffer from some bias incurred by some leading entries (in magnitude) of the associated vector. To neutralize this bias, we propose a class of models with partial regularizers for recovering a sparse solution of a linear system. We show that every local minimizer of these models is sufficiently sparse o...

Plasmonic metal nanostructures have shown great potential in sensing, photovoltaics, imaging and biomedicine, principally due to the enhancement of local electric field by light-excited surface plasmons, i.e., collective oscillation of conduction band electrons. Thin films of nanoporous gold have received a great deal of interest due to the unique 3-dimensional bicontinuous nanostructures with ...

We report single molecule fluorescence studies on nanoporous gold films. We observed dramatically enhanced intensities in individual immobilized fluorophores and reduced effective observation volumes in the nanopores. The enhanced localized plasmon field existing in the "nanovoid" regions can be visualized from the overlaid mapping image derived from surface reflectance and fluorescence emission.

"Even when NPM (New Public Management) was not fully implemented in continental Europe, it became clear that applying systematically performance driven market-type-mechanisms the public sector really matching its administrative law framed system. Also, our future society and will need a combined effort to ensure an inclusive service delivery, effective crises governance, functional innovation. ...

Abstract Under specific conditions, peritectic alloys can form microstructures that behave similar to regular eutectic alloys, with two solid phases growing in a coupled manner directly from the melt. This so-called couple growth (PCG) is significantly affected by convection. Thus, Bridgman-type experiments were performed onboard International Space Station using transparent alloy, tris(hydroxy...
