A Wheatstone bridge type thermal conductivity sample gas detector. A sensing element comprising one arm of the bridge is disposed in a constant temperature oven. A variable resistor, which functions as a reference element, and two fixed resistances comprise the second, third, and fourth arms of ...
where Kij is the hydraulic conductivity of the porous blocks, h is the hydraulic head, Ss is the specific storage, and q is the external source of fluid due, for example, to injection wells. Flow in each individual fracture can be reduced, under certain simplifying assumptions to give (8.2...
the test animals had to complete two sessions of ten trials each day, in which they each had to solve five addition and five subtraction tasks. Stimulus cards (stingrays) were laminated and measured 21.0 × 29.7 cm in size (A4). ...
One-dimensional (1D) nanomaterials have sparked widespread research interest owing to their fascinating physicochemical properties, however, the direct self-assembly of 1D porous nanomaterials and control over their porosity still presents a grand challe
One-piece cast, high-temperature resistant, thin-walled structures, the walls of which are connected with a cast-in connecting element with higher thermal ... One-piece cast, high-temperature resistant, thin-walled structures, the walls of which are connected with a cast-in connecting element ...
Furthermore, each control volume boundary, ∂KΩ, can be split into a finite number of faces σ⊂∂KΩ, such that σ=KΩ∩LΩ, with LΩ denoting a neighboring control volume. Integrating Eq. (3.11) over a control volume KΩ and applying the Gauss divergence theorem on Numerical ...
By measuring the low-temperature thermal conductivity, we conclude that Ta3Pd3Te14 is very likely a dirty s-wave superconductor. The emergence of superconductivity in Ta3Pd3Te14 with a lower Tc, compared to that of Ta4Pd3Te16, may be attributed to the lower density of states....
Graphene nanosheets have opened a new avenue for utilizing 2D carbon materials as catalyst support due to the high conductivity, huge specific surface area, and low fabrication cost11–13. One of popular methods for synthes- izing graphene supported metal NPs catalysts is the chemical reduction of...
where Z is the width of each element (shown between brackets). Another alternative embodiment is shown in FIG. 16. Compared with the circuit arrangement of FIG. 12, the transistor T3has been dispensed with, thus resulting in higher integration desnity. The condition to be satisfied in regard ...
A porphyrin ring-fusion polymer which consists of two or more Zn(II)-porphyrin rings fused in a single direction and in which any two porphyrin rings adjacent to each oth
