The management and maintenance of second generation sand-filled synthetic sports pitches [PDF]

open access: yes, 2008
Synthetic sports surfaces have increased in popularity since their introduction into the United Kingdom in the early 1970's. In many sports, such as hockey and athletics, they have become the standard for play.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Determination of fundamental criteria in the selection of a construction system

open access: yes, 2020
There is a lack of an efficient systematic approach to the selection of appropriate construction methods for modern building systems. Identifying key criteria is necessary to help decision-makers in implementing the principles of this process.

One–parametric semigroups of diffeomorphisms and one‐sided vector fields

open access: yesMathematical Modelling and Analysis, 2010
The fractional generalization of dynamical systems is considered. For this purpose, the concepts of fractional phase semi‐flow, fractional autonomous system and the generalized exponent of the vector field are introduced.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

A polyoptimal catalogue of rolled profiles for a given class of spatial trusses

open access: yesComputer Assisted Methods in Engineering and Science, 2023
The purpose of this polyoptimization was to find optimal tubular cross section catalogues for the specified spatial trusses. Five different spans of trusses have been analyzed, starting from 24 x 24 m ending at 72 x 72 m, trusses supported at every ...
