in this paper the factor of safety (fs) and critical line-segments slip surface obtained by the alternating variable local gradient (avlg) optimization method was presented as a new topic in 2d. results revealed that the percentage of reduction in the fs obtained by switching from a circular shape to line segments was higher with the avlg method than other methods. the 2d-avlg optimization meth...

Wall and Shortland (1991) have shown that afferent fibers entering the cord in thoracic and lumbar roots of adult rats have branches that may penetrate up to 11 segments caudally from the root entry zone. We have investigated the extent of branching and conduction velocities of ascending and descending branches of lumbar and thoracic primary afferents in isolated spinal cords of adult hamsters ...

Flame-retardant multilayer insulation materials act as effective thermal blankets of cryogenic containers that store flammable and explosive liquids. This study used standard static liquid nitrogen boil-off calorimetry to test the performance eight groups flame-retardant with different wrapping parameters. The effects four factors, namely layer density, seaming process, number reflector layer, ...

In non-destructive testing (NDT) it is important to have a high probability of detection (POD) and reliable characterization of each defect. This can be gained by using several techniques, which leads to an increase in cost and time for testing. Another option is to use several techniques combined into a single probe, in which case data fusion for the techniques is possible. A dual probe contai...

BACKGROUND Endogenous corticosteroids and endocannabinoids are both known to be involved in stress adaption and anti-inflammatory and immuneregulatory effects. The application of hair as retrospective specimen for long-term recording of corticosteroids and its association with stress-induced biochemical alterations was intensively examined. METHODS To evaluate the stability and correlation of...

The design of “smart” coatings and structural materials continue to offer immense promise in many emerging technologies ranging from self-healing coatings to stimuli-responsive drug delivery vehicles. Significant advances demand integration across length scales, ranging from non-covalent interactions and self-assembly at the nanometer dimension to the engineering and fabrication of functional d...
