In this paper, we report the effects of a N2 postmetallization annealing PMA on the reliability and charge-trapping characteristics of tungsten/La2O3/silicon structures. The samples are stressed with a constant-voltage stressing CVS with substrate injection. After the stressing we found that the flatband voltage VFB of the samples positively shifts, indicating a net negative charge trapped in t...

The precast segmental bridge has the advantages of fast construction speed, good economic performance, and small impact on surrounding environment. In order to study role temporary pre-stressing system in cantilever assembly process segment box girder bridge, ABAQUS was used simulate standard section a viaduct. Studying compressive stress relative sliding joint under action self-weight pre-stre...

Measuring mechanical implications of high current densities in microelectronic packaging interconnects has always been a challenging goal. Due to small interconnect size this task has typically been accomplished by measuring the change in electrical resistance of the joint. This measurement parameter is global and does not give local mechanical state information. Also, understanding strain evol...

Repairing and strengthening of existing aged steel-reinforced concrete structures is a major challenge. Today, much the repair work completed insufficient brittle. A promising new solution for tasks use iron-based shape memory alloy (Fe-SMA). The pre-strained Fe-SMA components enable pre-stressing building due to heat-triggered contraction steel. Thus, deflections can be reduced or even recover...

Pre-stressed members in various structures are gaining popularity among engineers many parts of the world because pre-stressed strands offer better stability, serviceability, economy, aesthetics, and structural efficiency. The profile strand greatly influences tensile strength concrete. force exerted by on concrete counterbalances internal forces. A construction engineer’s principal goal is to ...

In Heteroptera, the division of sex chromosomes is well defined as post-reductional for most of species, i.e., the first meiotic division is equational and the second is reductional. However, in some species pre-reductional division has been observed, whereby the first meiotic division is reductional and the second is equational. These include Anisops fieberi (Notonectidae), Ectrychotes dispara...

The kettlebell swing (KBS), emphasizing cyclical, explosive hip extension in the horizontal plane, aligns with movement- and velocity-specificity of sprinting. The present study examined the effect of an eight-week KBS intervention on sprinting in recreationally-active females, in comparison to an eight-week intervention using the stiff-legged deadlift (SDL). Following a pre-testing session mea...
