Methodical fitting for mathematical models of rubber-like materials
(The Royal Society Publishing, 2017-02-08)
A great variety of models can describe the nonlinear response of rubber to uniaxial tension. Yet an in-depth understanding of the successive stages of large extension is still lacking. We show that the response can be ...
Ecological variation in response to mass-flowering oilseed rape and surrounding landscape composition by members of a cryptic bumblebee complex
(Public Library of Science, 2013-06-19)
The Bombus sensu stricto species complex is a widespread group of cryptic bumblebee species which are important pollinators of many crops and wild plants. These cryptic species have, until now, largely been grouped together ...
Bumblebee learning and memory is impaired by chronic exposure to a neonicotinoid pesticide.
(Nature Publishing Group, 2015-11-16)
Bumblebees are exposed to pesticides applied for crop protection while foraging on treated plants, with increasing evidence suggesting that this sublethal exposure has implications for pollinator declines. The challenges ...
Manipulation of intestinal epithelial cell function by the cell contact-dependent type III secretion systems of Vibrio parahaemolyticus
(Frontiers Media, 2014-01-10)
Vibrio parahaemolyticus elicits gastroenteritis by deploying Type III Secretion Systems (TTSS) to deliver effector proteins into epithelial cells of the human intestinal tract. The bacteria must adhere to the human cells ...
Applications of raman spectroscopy in biopharmaceutical manufacturing: A short review
(Sage Publications, 2017-05-23)
The production of active pharmaceutical ingredients (APIs) is currently undergoing its biggest transformation in a century.
The changes are based on the rapid and dramatic introduction of protein- and macromolecule-based ...
Response of farmland biodiversity to the introduction of bioenergy crops: effects of local factors and surrounding landscape context
(Wiley Open Access, 2013-07-19)
The recent growth in bioenergy crop cultivation, stimulated by the need to implement measures to reduce net CO2 emissions, is driving major land-use changes with consequences for biodiversity and ecosystem service provision. ...
Pollination ecology of Desmodium setigerum (Fabaceae) in Uganda; do big bees do it better?
(2016-09)
Explosive pollen release is documented in many plant families, including the Fabaceae. Desmodium setigerum E. Mey (Fabaceae) is a perennial herb with single trip explosive pollen release found in eastern Africa, and the ...
Molecular simulation of nanoparticle diffusion at fluid interfaces
(2010)
Using molecular dynamics simulations the transport properties of a model nanoparticle in solution are studied. In bulk solvent the translational diffusion coefficients are in good agreement with previous simulation and ...
A refinement of a conjecture of Quillen
(Elsevier ScienceDirect, 2015-09)
We present some new results on the cohomology of a large scope of SL2 groups in degrees above the virtual cohomological dimension, yielding some partial positive results for the Quillen conjecture in rank one. We combine ...
Ignition delay times, laminar flame speeds, and mechanism validation for natural gas/hydrogen blends at elevated pressures
(Elsevier, 2013-12-30)
New experimental ignition delay time data measured in both a shock tube and in a rapid compression machine were taken to determine the increase in reactivity due to the addition of hydrogen to mixtures of methane and natural ...
