Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Ibo Island in the Quirimbas Archipelago. An Architectural Heritage Within a Natural Heritage
Conservation Science in Cultural Heritage, 2019 This paper presents the method adopted in the study of Ibo, a small island of the Quirimbas Archipelago in northern Mozambique. Ibo is part of a larger study, begun in 2004 which is still ongoing. In the first phase, the author's attention was focused on

FEBS Letters, EarlyView.LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Carbonatogenesis: microbial contribution to the conservation of monuments and artwork of stone
Conservation Science in Cultural Heritage, 2012 Over the last few decades there has been increasing global concern over the deterioration of historical monuments and stone works of art. It has posed a big challenge for the archaeologist, geobiologists and bioconservators and consequently encouraged ...

FEBS Letters, EarlyView.The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

A Conservative future ? Youth and the Conservative Party
Observatoire de la société britannique, 2007 Lors des élections législatives britanniques de 2005, environ 28 % des 18-24 ans qui ont participé au scrutin ont voté pour le Parti conservateur, contre 38 % pour le parti travailliste et 26 % pour le parti des libéraux démocrates. Clairement, le Parti conservateur n’était pas le premier choix de la plupart des jeunes électeurs, tout comme lors des ...

Truly Conserving with Conservative Remapping Methods
Geoscientific Model Development, 2023 Abstract. Conservative mapping of data from one horizontal grid to another should preserve certain integral or mean properties of the original data. This may be essential in some model applications, including ensuring realistic exchange of energy and mass between coupled model components.

Conservation Science in Cultural Heritage, 2018 The built heritage of the 1950s French colonial era represents the complexity of the hybrid cultural identity bequeathed by history but attracts minimal interest and consideration as an accepted local heritage. This research focuses on the opportunities

Discrete gradient methods have an energy conservation law [PDF]
arXiv, 2013 We show for a variety of classes of conservative PDEs that discrete gradient methods designed to have a conserved quantity (here called energy) also have a time-discrete conservation law. The discrete conservation law has the same conserved density as the continuous conservation law, while its flux is found by replacing all derivatives of the conserved

Conservative Integrators for Piecewise Smooth Systems with Transversal Dynamics [PDF]
arXiv, 2021 We introduce conservative integrators for long term integration of piecewise smooth systems with transversal dynamics and piecewise smooth conserved quantities. In essence, for a piecewise dynamical system with piecewise defined conserved quantities such that its trajectories cross transversally to its interface, we combine Mannshardt's transition ...
