Thermal fields can be easily controlled by changing the electric current intensity, as well as by the spatial distribution of thermal insulating materials over the surface of conduits.
The thermal constants of conduit materials are summarized in Table 1 [10].
Thermal constants of materials Fig. 2.
Based on the results of numerical experiments, we offer some design and engineering solutions for providing thermal conditions needed to ensure the effective operation of elements of the MHD-pump at its start.

HfO2 has been identified as one of the most promising materials for high-k replacement of SiO2 in the next generation complementary metal-oxide-semiconductor devices [3].
The packing density calculated from the refractive index data of HfO2 films at l = 633 nm (with ns = 2.1 for bulk material and nv for dry voids) is 0.88, 0.90, 0.94, and 0.95, respectively.

The rib adopted the same material and thickness with the tube and its width was 20mm.
According to the Chinese National standard, Metallic materials-tensile testing at ambient temperature (GB/T 228-2002), mechanical properties of the steel plate and reinforcement bars were tested.
The material properties are collected in Table 2.
In the study, the key factor for reinforcement stiffeners is embedment depth.

Introduction Approximately for two decades mathematical models and engineering methods have been available for predicting shape and hydrodynamic loads of complicate and complex fishing gears.
Therefore engineering methods are still necessary which approximately consider the relevant features of fluid-structure interactions like Priour & Herrmann (2006) did to predict the shape of cod-ends by statistical models.
Test plant, model and measuring methods All tests were carried out in the Large Sub-Sonic Wind Tunnel of the Department of Mechanical Engineering and Marine Technology of the University of Rostock.

In order to investigate the facture mechanism of weld bonded joint, optical microscopy and scanning electronic microscopy are used to check the material structure and the facture surfaces respectively.
In order to reduce car weight, the challenge for engineers is to design light-weight car bodies by means of new materials and joining technologies [1].
Experiments Material Description.
To control the adhesive thickness, small glass balls with 0.3mm diameter are added into the adhesive, as adhesive thickness is a key factor to guarantee good strength of adhesive bonded joint [11].
In the HAZ, shown in Fig. 4 (b), the material is recystallized into a fine structure that consists of bainite and ferrite.
