LMFBRs are considered to have the potentiality of transmuting the TRU nuclides effectively because of their hard neutron spectrum(’TRU’ means eventually minor actinide(MA) in the present study). Since MA Ioadkg considerably affects not only core characteristics but fuel material properties, it is necessary to investigate MA loading method taking into account the influence upon core characterist...

In mixed buildings of steel and concrete an economical design depends on intelligent solutions for steel-to-concrete joints. The verification joints is challenging, as the structural behaviour properties different materials have to be considered. Large forces often transferred in localized areas, e.g. bridge bearings, various failure modes may occur due load concentrations. An imposed preventin...

The experimental method of caustics was used for the evaluation of the stress-singularities created by concentrated oblique load applied at the apex of a wedge or on the horizontal straight boundary of a half-plane. The wedge was considered to be elastic, isotropic and under generalized plane stress conditions. According to the method of caustics, the light rays impinging normally at the thin p...

Lodgepole wood chips were pretreated by sulfite pretreatment to overcome recalcitrance of lignocelluloses (SPORL) at 25% solids loading and 180 °C for 20 min with sulfuric acid and sodium bisulfite charges of 2.2 and 8 wt/wt% on an oven-dry wood basis, respectively. The pretreated wood chips were disk-milled with pretreatment spent liquor and water, and the solid fraction was separated from the...

today, corrosion in reinforcements is an important issue in many structures, especially those made in off-shore, resulting of reduction of the structural capacity under gravitational and lateral loads. using frp polymer can reduce this effect to some extents. a numerical and experimental investigation has been conducted on three different concrete beams to find out the effect of replacing steel...

in this paper, exact solution for two-plane transverse vibration analysis of axial-loaded multi-step timoshenko rotor carrying concentrated masses is presented. each attached element is considered to have both translational and rotational inertia. forward and backward frequencies and corresponding modes are obtained using transfer matrix method (tmm). the effect of the angular velocity of spin,...

We examine the question of whether living in a disadvantaged neighborhood damages health, over and above the impact of personal socioeconomic characteristics. We hypothesize that (1) health correlates negatively with neighborhood disadvantage adjusting for personal disadvantage, and that (2) neighborhood disorder mediates the association, (3) partly because disorder and the fear associated with...

In order to increase the accuracy of evaluating seismic response of structures, it is critical to conduct dynamic analyses based upon precise nonlinear models being as consistent as possible with the real conditions of corresponding structures. The concentrated plasticity model including one elastic element and two nonlinear spring elements at both ends has been considered within the research c...
