Glucose Transport and Transporters in the Endomembranes [PDF]

International Journal of Molecular Sciences, 2019
Glucose is a basic nutrient in most of the creatures; its transport through biological membranes is an absolute requirement of life. This role is fulfilled by glucose transporters, mediating the transport of glucose by facilitated diffusion or by secondary active transport.

A study into urban roadworks with shuttle-lane operation [PDF]

, 1998
In urban areas where roadworks are required, single lane shuttle operation is applied, especially where there is limited road space. There are operational problems relating to the site such as site geometry, visibility, length of roadworks zone ...

Under which conditions is carrier cooperation possible? A case study in a Seville marketplace [PDF]

, 2018
The high volume of traffic originates two well-known problems in many cities: congestion and pollution. In recent years, a social phenomenon is emerging cooperation.

Transport and transporters in the endoplasmic reticulum

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2007
Enzyme activities localized in the luminal compartment of the endoplasmic reticulum are integrated into the cellular metabolism by transmembrane fluxes of their substrates, products and/or cofactors. Most compounds involved are bulky, polar or even charged; hence, they cannot be expected to diffuse through lipid bilayers.

London 2012: changing delivery patterns in response to the impact of the Games on traffic flows [PDF]

, 2014
The paper addresses road freight transport operations during the London Olympic and Paralympic Games in 2012. It presents work carried out prior to the Games to understand pre-Games patterns of freight deliveries in London (for both light and heavy goods

Lighting for cycling in the UK : a review [PDF]

, 2015
While UK governments have recently sought to increase cycling activity, it remains a minority interest. One reason for this is the perceived danger of cycling on roads filled with traffic.

Nitrate transporters and peptide transporters

FEBS Letters, 2007
In higher plants, two types of nitrate transporters, NRT1 and NRT2, have been identified. In Arabidopsis, there are 53 NRT1 genes and 7 NRT2 genes. NRT2 are high‐affinity nitrate transporters, while most members of the NRT1 family are low‐affinity nitrate transporters.

A simple reactive-transport model of calcite precipitation in soils and other porous media [PDF]

, 2015
Calcite formation in soils and other porous media generally occurs around a localised source of reactants, such as a plant root or soil macro-pore, and the rate depends on the transport of reactants to and from the precipitation zone as well as the ...

Transport Dynamics in a Glutamate Transporter Homologue [PDF]

Biophysical Journal, 2013
Glutamate transporters are integral membrane proteins that catalyse neurotransmitter uptake from the synaptic cleft into the cytoplasm of glial cells and neurons. Their mechanism of action involves transitions between extracellular (outward)-facing and intracellular (inward)-facing conformations, whereby substrate binding sites become accessible to ...
