In a constriction

For a surface containing area in pores which possess constrictions leading into wide inner bodies, one can approximate the ratio of the adsorption rates of the more accessible parts of the surface and the portion of the surface in the wide inner body. If the adsorption potential in a constriction is 2 kcal more than that on an open surface, the ratio of adsorption rates at liquid-nitrogen temperature, assuming the same preexponential value A, will be... 

A modified read-out structure is shown in GB-A-2201834 where each semiconductor strip branches into two parts separated from each other by a slot. This narrowing of the drift path results in a constriction of the bias current and so introduces a higher electric field which increases both the drift velocity and the sensitivity of the device. 

In a constriction of a metal with nanometer dimensions, called a nanowire, the ballistic transport of electrons occurs in conductive chaimels. The number of channels is proportional to the width of the nanowire. The conductance of such nanowire is described by Landauer s formula [2] ... 

If a boiling solution of mass flux, L, is partially expanded in a constriction by experiencing a differential pressure drop dp, the solution is cooled by AT and expansion vapor of flow rate AD is generated (expansion evaporation under isenthalpic throttling at boiling conditions). A heat balance over the constriction with steam separator gives... 

Dielectric materials always display an elastic deformation when stressed by an electric field due to displacements of ions within the crystal lattice. The mechanism of polarization, i.e., the shifting of ions in the direction of an applied field, results in a constriction of surrounding ions in the atomic lattice, as restoring forces between atoms seek to balance the system. This behavior is called electrostriction and is common to all crystals endowed with a center... 

Alkyl mercury is much more dangerous - methyl mercury is an example. It causes irreversible damage to the brain, resulting in a constriction of visual fields, disturbance of speech, deafness and inco-ordination of movement. Most of it (90%) is excreted without change, slowly in the faeces.
